Description

  The present invention relates to a water stop structure and a fitting, and more specifically, a water stop structure that is provided at an end of a frame member having a hollow portion to prevent intrusion of water or the like from a small opening of the hollow portion, and the water stop structure. It relates to the fittings provided.

  Conventionally, as a water-stopping structure (watertight structure) of a joint portion of a frame material in a window frame, a small cap (vertical frame cap) that closes a small opening that opens at the upper and lower ends of a vertical frame having a hollow portion (hollow portion), A structure including a back-up material (backer) provided on the inner side of the hollow portion than the small cap and a wet seal material (caulking material) filled between them has been proposed (see, for example, Patent Document 1). ).

Utility Model Registration No. 2595501

  However, in the conventional water stop structure described in Patent Document 1, the backup material is pushed into the hollow portion of the frame material and the position thereof is held by the elasticity, and the sealing material extends from above the backup material to the vicinity of the edge of the frame material. Since the small cap is attached while pressing the sealing material before solidifying, the sealing material pressed against the small cap may overflow from the small opening. For this reason, the overflowing sealing material forms a film on the outer surface of the frame material, and this film reduces the adhesive force of the external seal that seals the building opening and the frame material, and impairs the waterproof performance of the joinery. There is a fear. In addition, since the push-in distance (holding position) when pushing the backup material into the hollow part is indefinite, for example, if the holding position is too shallow, the thickness of the sealing material is insufficient, or the backup material has a small cap. In any case, the water stoppage performance will be reduced, such as making a water supply.

  The objective of this invention is providing the water stop structure and fittings which can ensure the water stop performance in the small edge position in the frame material which has a hollow part.

  The water stop structure of the present invention is a water stop structure provided at an end of a frame member having a hollow portion, and a small cap that closes the small opening of the hollow portion, and on the inner side of the hollow portion than the small cap. A backup material provided, and a sealing material filled between the small cap and the backup material, and a sliding contact member made of an elastic material is attached to the inside of the hollow portion of the small cap, The sliding contact member is provided in a state of being pressed against the inner surface of the hollow portion, and the small contact cap is attached to the frame member while the sliding contact member is in contact with the filled sealing material.

  According to the present invention described above, the sliding contact member made of an elastic material attached to the small cap is brought into sliding contact with the inner surface of the hollow portion (hollow portion), so that the sliding contact member functions as a piston and the small cap is attached. At this time, the sealing material can be pushed into the inside of the hollow portion by the sliding contact member, and the sealing material can be prevented from overflowing from the edge of the frame material. Therefore, there is no possibility of causing a decrease in water stoppage between the building opening and the frame member due to the overflowing sealing material, and water stop performance can be ensured.

At this time, in the water stop structure of the present invention, the sliding contact member is provided between the small cap and the hollow portion of the frame member, and has a protruding portion that closes the gap between the small cap and the hollow portion. Is preferred.
According to such a configuration, the gap between the small cap and the hollow portion (hollow portion) can be closed by the protrusion of the sliding contact member, and water can be prevented from entering from the gap between the small cap and the hollow portion. it can.
In particular, when the fore edge cap and frame material are made of metal such as an aluminum profile, the metal touch part where the fore edge cap and the hollow part of the frame material come into direct contact with each other when the end edge cap (small edge) is fitted into the edge of the frame material It becomes. A minute gap is easily formed in the metal touch part, and when the external seal (an enclosure seal) for sealing the building opening and the frame material is provided on the small cap, the gap of the metal touch part becomes water. There is a risk that water may enter the indoor side from the outdoor side of the external seal.
On the other hand, according to the present invention, the gap between the small cap and the hollow portion is closed by the protruding portion of the sliding contact member made of an elastic material. It is possible to prevent water from entering the indoor side.

Furthermore, in the water stop structure of the present invention, the hollow portion of the frame member includes two prospective surfaces facing each other and two finding surfaces facing each other, and the small cap is disposed apart in the finding direction. It is preferable that the two slidable contact members are attached, and the protrusions of the slidable contact members block the gap between the small cap and the prospective surface of the hollow portion.
According to such a configuration, the hollow portion (hollow portion) of the frame member has a rectangular cross-sectional shape, and includes two prospective surfaces and a finding surface. Then, two sliding contact members are attached to the small cap, and the gap between the small cap and each prospective surface of the hollow portion is closed by the projection of each sliding contact member. In various window frames and the like having different width dimensions (finding dimensions) of the hollow portion of the frame material, the width dimension of the fore cap needs to be matched to the width dimension of the hollow portion. On the other hand, if the slidable contact member is composed of two members, the slidable contact member can be arranged apart in the width direction (finding direction) of the fore cap, so the same part is used regardless of the difference in the width dimension of the hollow portion. be able to. For this reason, it is not necessary to manufacture the sliding contact member from which a width dimension differs according to the width dimension of a fore edge cap, and can reduce the kind of sliding contact member and can improve manufacturing efficiency.

Under the present circumstances, in the water stop structure of this invention, it is preferable that the said backup material is press-fit in the state which can be slidably contacted with the inner surface of the said hollow part.
According to such a configuration, since the backup material is not fixed to the inside of the hollow portion by the fixing tool or the like, the pressure of the sealing material can be increased by strongly pressing the sealing material into the inside of the hollow portion by the sliding contact member. Backup material can also be pushed in. Therefore, for example, even when the holding position of the backup material is too shallow or when the sealing material is filled too much, the backup material is pushed through the sealing material into the inside of the hollow portion and moved. The distance between the cap and the backup material can be appropriately secured. This ensures the thickness of the sealing material and prevents the small cap and the backup material from coming into direct contact with each other. A decrease in water performance can be prevented.

Furthermore, in the water stop structure of the present invention, it is preferable that an escape portion for allowing the seal material to escape to the inside of the hollow portion is formed in the backup material.
According to such a configuration, as described above, even when the sealing material is excessively filled, the sealing material is released from the escape portion of the backup material to the inner side of the hollow portion, so that the gap between the small cap and the backup material is reduced. The amount of the sealing material can be adjusted, and the excess sealing material can be reliably prevented from overflowing from the small opening.

Further, in the water stop structure of the present invention, the backup material is fixed to a predetermined position inside the hollow portion with a fixing tool, and the back-up material has an escape portion for allowing the sealing material to escape to the inside of the hollow portion. May be formed.
According to such a configuration, by fixing the backup material at a predetermined position inside the hollow portion, the distance between the backup material and the fore edge cap can be set according to the set value, and the thickness dimension of the seal material can be set to a predetermined value. The water stop performance can be secured as a value. Even when the backup material is fixed inside the hollow part, the back-up material has a relief part that allows the seal material to escape, so even if the seal material is filled too much, excess sealing material overflows from the small opening. It can be surely prevented from taking out.

On the other hand, the joinery of the present invention is characterized by including a frame member and any one of the water stop structures provided at an end of the frame member.
According to such a joinery of the present invention, substantially the same effect as the water stop structure described above, that is, the water stop structure prevents water and the like from entering the hollow portion of the frame member, and the frame member has a small edge when built. By preventing the sealing material from overflowing, the adhesive force of the external seal between the frame material and the building opening can be surely exhibited, and the waterproof performance as a fitting can be ensured.

  As the water stop structure 10 of this embodiment, the same structure is provided in the upper-lower end part of the vertical frame 4, respectively, However, the water stop structure 10 provided in the upper end part of the vertical frame 4 is demonstrated in detail below. Here, as shown in FIG. 4, the upper frame 2 and the vertical frame 4 are in a state in which the longitudinal edge 2A of the upper frame 2 is in contact with the inner surface in the direction of finding of the prospective surface portion 41 of the vertical frame 4. The vertical frame 4 is joined by screwing a screw 4 </ b> A penetrating from the outside in the direction of finding into the screw hole 2 </ b> B of the upper frame 2. Further, the screw 4A is inserted into an insertion hole 44A formed in the second prospective surface 44 of the hollow portion 42 so as to penetrate the first prospective surface 43. The adhesive seal 44B is attached to the insertion hole 44A. It is attached and blocked.

  The water stop structure 10 includes a small cap 11 that closes the small opening 42A of the hollow portion 42, a backup material 12 that is provided on the inner side of the hollow portion 42 than the small cap 11 (the back side in the insertion direction of the small cap 11), and these A sealing material 13 filled between the small cap 11 and the backup material 12, and a sliding contact member 14 provided on the inner side (the sealing material 13 side) of the hollow portion 42 in the small cap 11. Yes.

  The forehead cap 11 is a short member made of an aluminum shape member, and has a closed surface 21 provided flat with the edge of the forehead 42A in the mounted state, and a rising piece 22 rising from the indoor side end of the closed surface 21. An extension piece 23 that slightly rises from the outdoor side end of the blocking surface 21 and extends to the outdoor side, and a pair of latches that extend from the indoor side and outdoor side ends of the blocking surface 21 to the inside of the hollow portion 42, respectively. And a piece 24. At the tip of the pair of locking pieces 24, a pair of holding pieces 25 extending in a direction approaching each other and holding the sliding contact member 14, and a pair of sliding contact portions 26 projecting in the opposite direction to the holding pieces 25. And the slidable contact portion 26 is in slidable contact with the first and second finding surfaces 45 and 46 in a pressed state so that the small cap 11 is locked to the small lip 42A of the hollow portion 42. It has become. In addition, a stepped portion 27 formed in a stepped shape with respect to the closing surface 21 is formed at the proximal end portion of the rising piece 22 in the small cap 11, similarly to the extended piece 23, and these extended pieces 23 and the stepped portion 27 can come into contact with upper end edges of the first and second finding surfaces 45 and 46, respectively. Further, the pair of sliding contact portions 26, the extending piece 23, and the stepped portion 27 are respectively continuous in the width direction of the fore edge cap 11 (the direction in which the vertical frame 4 is found and the depth direction in FIG. 2A). It is formed over the entire width of the fore edge cap 11 and is configured to be able to abut the substantially entire length of the first and second finding surfaces 45 and 46.

  The slidable contact member 14 held by the pair of holding pieces 25 is made of an elastic material made of foamed resin, and is attached in close contact with the closing surface 21 of the forehead cap 11. The sliding contact member 14 has a width in a direction in which it can be slidably contacted with the first and second prospective surfaces 43 and 44 of the hollow portion 42 in a pressed state, that is, in a state before being attached to the small opening 42A. It is formed with a width dimension slightly larger than the distance between the first and second prospective surfaces 43 and 44, and is configured to be able to come into close contact with the first and second prospective surfaces 43 and 44 when attached to the fore edge 42A. Has been.

  The backup material 12 is formed of an elastic material made of foamed resin, and is separated from the first and second prospective surfaces 43 and 44 that are recessed from the main body 121 and pressed into the hollow portion 42. And a pair of recessed portions (relief portions) 122 provided. This backup material 12 is press-fitted in a non-fixed state into the hollow portion 42 without using a fixing tool such as a screw, that is, the main body portion 121 has the first and second prospective surfaces 43 and 44 and the first and second finding. While being in sliding contact with the surfaces 45, 46, it is pushed into the inside of the hollow portion 42 from the small opening 42 </ b> A, and a frictional force is generated between the hollow portion 42 due to its elasticity, so that the inside of the hollow portion 42. It is supposed to be retained.

  The sealing material 13 is a wet water-stopping material supplied by a caulking gun G or the like. Then, the small opening 42A is closed by the small cap 11 and the sliding contact member 14, so that the backup material 12, the small cap 11 and the sliding contact member 14 are filled. Then, the sealing material 13 is solidified and becomes an elastic body after filling, so that the inside of the hollow portion 42 is sealed and water is stopped. As shown in FIG. 2, the sealing material 13 enters the recess 122 of the backup material 12 and bulges by attaching the small cap 11 and the sliding contact member 14 and pressing the sealing material 13 before solidifying. By forming the portion 13 </ b> A, it is possible to escape to the inside of the hollow portion 42, that is, the escape portion is constituted by the recess 122.

  As the construction procedure of the water stop structure 10 described above, first, the upper frame 2 and the vertical frame 4 are joined with screws 4A, and the insertion member 44A of the hollow portion 42 is closed with the adhesive seal 44B. It press-fits into the hollow part 42 from the small opening 42A, and pushes it to such an extent that the upper surface of the backup material 12 is located inside the hollow part 42 from the head of the screw 4A. At this time, one recess 122 of the backup material 12 passes through the head of the screw 4A, so that the backup material 12 is not caught by the screw 4A during the press-fitting. Next, the sealing material 13 is injected on the upper side of the backup material 12, and the injection is terminated when the upper surface of the sealing material 13 rises to a position slightly lower than the small opening 42A so as not to overflow from the small opening 42A. At this time, the sealing material 13 does not enter (or is difficult to enter) the recess 122 of the backup material 12 due to its viscosity.

  Next, the forehead cap 11 to which the sliding contact member 14 is attached is attached to the forehead 42A. At this time, the air between the upper surface of the seal member 13 and the sliding contact member 14 escapes from the hollow portion 42 through a fine gap between the sliding contact portion 26 and the first and second finding surfaces 45 and 46. However, the sealing material 13 having viscosity does not pass through the clearance between the sliding contact portion 26 and the sliding contact member 14 and the inner surface of the hollow portion 42, and the sliding contact portion 26 and the sliding contact member 14 function as a piston. The sealing material 13 is pushed toward the backup material 12 in a compressed state. A part of the sealing material 13 pushed in this way enters the recess 122 as the bulging portion 13A, so that the pressure of the sealing material 13 does not increase too much so that the sealing material 13 does not overflow to the small opening 42A side. It has become. By attaching the respective members as described above, the sealing material 13 is filled between the small cap 11 and the sliding contact member 14 and the backup material 12 without excessive air entering. The inside of 42 is sealed. Further, in the state where the small cap 11 is attached, the screw 4A is located between the backup material 12 and the sliding contact member 14 (that is, located facing the space filled with the seal material 13). 12, the sliding contact member 14, and the fore edge cap 11 do not interfere with the screw 4 </ b> A, and adverse effects caused by the interference (for example, water entering the upper frame 2 through the screw hole) can be prevented.

  According to the above embodiment, the sliding contact portion 26 and the sliding contact member 14 of the small cap 11 are made to function as a piston, and the sealing material 13 is pushed into the backup material 12 in a compressed state. The sealing material 13 can be prevented from overflowing from 42 </ b> A, and the inside of the hollow portion 42 can be sealed with the sealing material 13, so that the water stop performance of the water stop structure 10 can be enhanced. Further, by preventing the sealing material 13 from overflowing, the trouble of wiping off the overflowing sealing material 13 can be omitted, and the adhesion between the external seal S and the window frame 5 can be improved, and the sliding window 1 as a whole. As a result, the water stop performance can be secured.

  In addition, the form of the sliding contact member 14 in this embodiment is not limited to the above-described one, and as shown in FIG. 5, the contact piece 141 that extends to the inside of the hollow portion 42 and can contact the backup material 12 is provided. You may have. If such a contact piece 141 is formed on the sliding contact member 14, even if the holding position of the backup material 12 press-fitted into the hollow portion 42 is shallower than a predetermined depth, the small cap 11 and the sliding contact member 14. When attaching the backup material 12, the contact piece 141 can further push the backup material 12 into the hollow portion 42. Therefore, the backup material 12 and the sliding contact portion 26 of the small cap 11 can be prevented from coming into direct contact with each other, and the sliding contact portion 26 can be prevented from entering rainwater and the like as water. Further, by pushing the backup material 12 into the hollow portion 42 and moving it, the distance between the small cap 11 and the sliding contact member 14 and the backup material 12 can be appropriately secured, and the thickness of the sealing material 13 It is possible to ensure the water stop performance by ensuring the dimensions.

[Second Embodiment]
The water stop structure 10A according to the second embodiment of the present invention is different in that the backup material 15 is used instead of the backup material 12 of the water stop structure 10 in the first embodiment. This is substantially the same as the embodiment. Hereinafter, the difference will be described in detail with reference to FIGS.
The backup material 15 is a hard member made of metal or resin, and includes a fixed piece portion 151 along the first prospective surface 43 of the hollow portion 42 and a bottom surface portion extending from the fixed piece portion 151 toward the second prospective surface 44 side. 152, and is formed in an overall L-shape. The fixing piece 151 is formed with a locking hole 153 through which the shaft of the screw 4A can be inserted and can be locked to the head of the screw 4A. An escape hole 154 is formed as an escape portion for escape on the inner side of 42.

  As a construction procedure of such a water stop structure 10A, first, when the upper frame 2 and the vertical frame 4 are joined with the screw 4A, the locking hole 153 of the backup material 15 is hooked on the head of the screw 4A. By tightening the screw 4 </ b> A, the backup material 15 is fixed to the first prospective surface 43 of the hollow portion 42. Thereafter, the construction procedure is substantially the same as in the first embodiment. After the insertion hole 44A of the hollow portion 42 is closed with the adhesive seal 44B, the sealing material 13 is injected into the hollow portion 42, and the sliding contact member 14 is fixed. The attached forehead cap 11 is attached to the forehead 42A. At this time, the slidable contact portion 26 and the slidable contact member 14 of the small cap 11 function as a piston, and a part of the sealing material 13 pressed thereby is formed as a bulging portion 13A from the escape hole 154 to the inside of the hollow portion 42. By escaping, the pressure of the sealing material 13 does not become too high and does not overflow to the small opening 42A side. Also with the water stop structure 10A of the second embodiment, it is possible to obtain substantially the same function and effect as the first embodiment. Further, the mounting position of the backup material 15 can be always fixed by being fixed to the screw 4A connecting the upper frame 2 and the vertical frame 4.

[Third Embodiment]
The water stop structure 10B according to the third embodiment of the present invention is different in that the slide contact member 50 is used instead of the slide contact member 14 of the water stop structure 10 in the first embodiment. This is substantially the same as the first embodiment. Hereinafter, the difference will be described in detail with reference to FIGS.

  The sliding contact member 50 is an elastic member made of synthetic resin such as PVC (polyvinyl chloride), and is manufactured by extrusion molding. As shown in FIG. 10, the sliding contact member 50 includes a flat surface 51 that is in contact with the closing surface 21 of the forehead cap 11, a protruding portion 52 that protrudes from an edge of the flat surface 51, and a side surface 53 that is continuous with the protruding portion 52. The fin portion 54 projecting from the side surface 53, the holding surface 55 facing the holding piece 25, the projecting portion 56 projecting from the retaining surface 55, and the projecting portion 56 are continuous from the proximal end portion of the fin portion 54. And an end surface 58 that connects the inclined surface 57 and the flat surface 51.

The sliding contact member 50 is attached from the side surface of the fore edge cap 11. That is, the tip end surface 58 side of the sliding contact member 50 is pushed in from the side surface opened between the closing surface 21 and the holding piece 25 and attached. At this time, the height dimension of the front end surface 58 is made smaller than the opening height dimension between the closing surface 21 and the holding piece 25. For this reason, when the sliding contact member 50 is inserted into the side opening of the fore cap 11, the inclined surface 57 is guided in contact with the holding piece 25, so that the sliding contact member 50 can be inserted smoothly.
Further, a protrusion 56 continuous with the inclined surface 57 is formed, and the height dimension from the flat surface 51 to the tip of the protrusion 56 is made larger than the height dimension of the side opening of the fore edge cap 11. For this reason, as shown in FIG. 10, when the sliding contact member 50 is attached to the fore edge cap 11, the protrusion 56 is bent and the flat surface 51 is in close contact with the closing surface 21.

  The protruding portion 52 is disposed on the outer side of the side surface of the blocking surface 21, that is, the side surface of the hollow portion 42 that faces the first prospective surface 43 and the second prospective surface 44. Therefore, when the small cap 11 to which the sliding contact member 50 is attached is inserted into the hollow portion 42 from the small opening 42A of the vertical frame 4, as shown in FIG. 11, specifically, between the first prospective surface 43 and the second prospective surface 44 and the side surface of the closing surface 21 of the forehead cap 11, and closes the gap between them.

Further, as shown in FIG. 10, the fin portion 54 protrudes outward in the direction of finding from the protruding portion 52. For this reason, as shown in FIG. 11, when the fore edge cap 11 is inserted into the hollow portion 42, the fin portion 54 contacts the prospective surfaces 43 and 44. Accordingly, the sliding contact member 50 is provided in a state where the fin portion 54 is pressed against the inner surface of the hollow portion 42.
At this time, the fin portion 54 is inclined obliquely upward in FIG. Further, the side surface 53 of the sliding contact member 50 is formed with a concave portion 53 </ b> A that is inclined obliquely toward the proximal end portion of the fin portion 54.
For this reason, when the small cap 11 is inserted into the hollow portion 42 from the small opening 42A, the fin portion 54 is bent in contact with the small opening 42A. At this time, since the concave portion 53 </ b> A is formed, the fin portion 54 is smoothly bent and comes into contact with the prospective surfaces 43 and 44 which are the inner surfaces of the hollow portion 42.

  Further, since the side surface 53 continuous to the protrusion 52 is formed obliquely, when the small cap 11 is further pushed into the hollow portion 42, the side surface 53 comes into contact with the small opening 42A, and the small cap 11 is smoothly hollow. The protrusion 52 is pushed into the portion 42 and is sandwiched between the inner surface of the hollow portion 42 and the fore edge cap 11. For this reason, the gap between the prospective surfaces 43 and 44 which are the inner surfaces of the hollow portion 42 and the metal touch portion between the fore edge cap 11 is closed by the protruding portion 52.

Also in this embodiment, the same effect as the first embodiment can be obtained.
Furthermore, since the protrusion 52 closes the gaps between the small cap 11 and the prospective surfaces 43 and 44, it is possible to prevent water from being generated, and to prevent water from entering the indoor side from the outdoor side of the external seal S. That is, when the external seal S is provided between the opening O and the window frame 5, the external seal S is continuously provided in the direction of finding the small cap 11. For this reason, the upper surface of the protrusion 52 is in close contact with the external seal S, and the generation of water supply can be prevented. For this reason, the waterproof performance of joinery can be improved.

  Further, since the fin portion 54 of the sliding contact member 50 is provided in a state where it is pressed against the inner surface of the hollow portion (hollow portion) 42 of the vertical frame 4, a water pipe is provided between the sliding contact member 50 and the inner surface of the hollow portion 42. Can also be prevented. For this reason, the waterproof performance of joinery can be improved more.

Further, since the sliding contact member 50 is composed of two members, the sliding contact member 50 can also be used in various fittings having different width dimensions in the direction of finding the small cap 11 and the hollow portion 42. For example, as shown in FIG. 12, even when the hollow portion 42 has a larger width dimension than that shown in FIG. Since it can arrange | position apart in the direction of finding the forehead cap 11, the same thing as the sliding contact member 50 shown in FIGS.
Furthermore, each sliding contact member 50 has the same cross-sectional shape, and is attached to the forehead cap 11 by changing its orientation. For this reason, since one kind of sliding contact member 50 is manufactured by extrusion molding and cut according to the expected length of the small cap 11, the manufacturing efficiency of the sliding contact member 50 can be improved and the manufacturing cost is also reduced. it can.
In addition, if the sliding contact member 50 is composed of two members, one protrusion 52 may be provided for each sliding contact member 50.
