Background technique

In order to improve the design of the building's outer wall, external wall panels such as ceramics, which have been subjected to surface pattern treatment such as natural stone style/brick tile style, are often attached to the outer wall of the building. The installation method of the outer wall panel includes the horizontal installation method of attaching the longitudinal direction of the outer wall panel to the frame side as the horizontal direction (horizontal direction), and the vertical installation method of attaching the longitudinal direction of the outer wall panel to the frame side as the longitudinal direction (vertical direction) . Usually, the upper and lower end faces of the outer wall panels adopting the longitudinal installation method are planes, and real parts are formed on the left and right ends. At the joints of the left and right adjacent outer wall panels, a snap joint using the real part is performed, and at the mutual joints of the vertically adjacent outer wall panels, an appropriate member is sandwiched between the ends of the outer wall panels.

Fig. 7 is a cross-sectional view showing an example of the upper and lower joint portions of the outer wall panel mounted by the vertical mounting method. In this example, the outer wall panels 30A, 30B are attached to the horizontal bar 91 using nails 95 in a state where the convex portion 42 of the cap-shaped connector 40 is sandwiched between the upper and lower adjacent outer wall panels 30A, 30B, and the cap is attached to the horizontal bar 91 from the cap. The sealing material 97 is filled above the connector 40 . The horizontal strip board 91 is fixed to a pillar or an intermediate pillar (not shown) via a waterproof paper 93 . The cap connector 40 is composed of a base plate 41 to be fixed to the horizontal strip 91 and a protrusion 42 protruding from the surface side of the base plate 41. By using the cap connector 40, the upper and lower outer wall panels 30A, 30B are separated by a desired interval.

Fig. 8a shows another construction example of the upper and lower joints. In this construction example, the middle drip gutter 50 is interposed between the upper and lower outer wall panels 30A and 30B, and is attached. The middle drip channel 50 is composed of a base plate 51 serving as a fixing surface fixed to the horizontal bar 91 , a step portion 52 formed at the lower end of the base plate 51 , and a drip portion 53 extending from the lower end of the step portion 52 toward the surface side. As shown in the figure, the lower end of the upper outer wall plate 30A is placed on the step portion 52 of the middle drip tank 50, and the dripping portion 53 protrudes toward the surface side from between the upper and lower outer wall plates 30A, 30B, and in this state, it is removed from the upper surface. The surfaces of the outer wall panels 30A and 30B are fixed by driving nails 95 into the horizontal strips 91 .

In addition, as a similar example to the above-mentioned middle drip tank 50, a middle drip tank having a shape in which the step portion 52 is removed is often used.

Fig. 8b shows another construction example of the upper and lower joints (refer to Patent Document 1).

In the construction structure shown in FIG. 7 , the durability of the sealing material 97 is problematic, and there is a possibility that the sealing material 97 may be peeled off due to infiltration by rainwater. In addition, since the sealing material 97 is filled between the upper and lower outer wall panels 30A, 30B, a joint groove having a certain depth cannot be formed, which causes a slight problem in the design of the joint portion.

In the construction structure shown in Figure 8a, it is necessary to adjust the distance between the ends of the upper and lower outer wall panels 30A, 30B, that is, it is necessary to adjust the positions of the outer wall panels 30A, 30B so that the joint width becomes a desired certain width, Therefore construction is very troublesome. In addition, the dripping portion 53 of the middle dripping groove 50 covers the front surface of the upper end of the lower outer wall panel 30B, and the joint groove cannot be in a straight line in the horizontal direction. The appearance of the drip part 53 being separated.

In the construction structure shown in FIG. 8b, the shape of the middle drip groove 60 is complex, and in order to support the weight of the upper outer wall panel 30A, it is necessary to make the middle drip groove 60 into an aluminum molded product or the like, resulting in an increase in cost. In addition, in order to stably maintain the vicinity of the lower end of the outer wall panel 30A, the upper front panel 63 must have a relatively large width, which in turn causes the width of the lower front panel 65 to be exposed in front of the upper end of the outer wall panel 30B. It becomes an appearance in which the surface patterns of the upper and lower outer wall panels 30A, 30B are clearly divided.

Contents of the invention

The present invention was made in view of the above-mentioned problems, and an object of the present invention is to provide a seam material that is low in manufacturing cost, easy in construction, and capable of forming a seam portion with high designability and high water-cutting performance.

In order to solve the above problems, the present invention provides a joint member fixed between upper and lower adjacent outer wall panels in the construction of the outer wall by nailing the fixing member from the surface side and installing the outer wall panels on the frame side of the building, which is at least It includes: a lower edge portion near the upper end which is crimped on the surface of the lower outer wall panel during construction; and a joint groove portion extending upward from the upper end of the lower edge portion and toward the back side.

In the construction structure of the outer wall using the seam of the present invention, since the lower edge of the seam is exposed to the front of the outer wall, the lower edge is different from the dripping part 53 shown in FIG. The surface of the board, so even with a small width, it can definitely prevent the intrusion of rainwater. Therefore, although the lower edge part of the seam is exposed, it is inconspicuous because its width is very small. In addition, since the seam material of the present invention can form a seam groove having a certain depth by the seam groove portion, a highly designed seam portion can be formed. Furthermore, it is also possible to prevent rainwater from penetrating into the joint portion of the upper and lower outer wall panels. In addition, since the joint member of the present invention can be provided with a simple shape, it is easy to manufacture, and because it does not need to support the weight of the outer wall panels like the middle drip tank 60 shown in FIG. 8 b , it can use low-cost materials.

Preferably, an elastic water-cutting member is pasted on the back of the lower edge, and this can improve the closeness between the lower edge and the surface of the outer wall, and can more reliably prevent rainwater from infiltrating.

In a preferred embodiment, the seam is composed of a hat-shaped connector and a seam cover, and the hat-shaped connector is composed of a base plate serving as a fixing surface fixed to the building frame side, and a base plate that protrudes from the base plate toward the surface side. The convex portion sandwiched between the ends of the upper and lower outer wall panels during construction is composed of the upper and lower sides and the top surface connecting the upper and lower sides. The joint cover is installed after the joint is installed. In the state of the seam and the upper and lower outer wall panels, only the top surface of the convex part of the hat-shaped connector and the upper end surface of the lower outer wall panel are covered, and it includes a seam groove and a lower edge.

The seam of this mode can easily leave a desired interval between the upper and lower outer wall panels by using the hat-shaped connector, and can keep the seam width at a certain size. In addition, both the cap connector and the seam cover can be made to have simple shapes, and thus are easy to manufacture.

Preferably, the seam groove portion of the seam cover member is formed such that a part of the seam groove portion is crimped to the convex portion of the cap connector when the seam member and the upper and lower outer wall panels are attached. The size of the top surface. Thereby, the joint groove as deep as possible can be formed, and rainwater can be prevented from entering between the joint groove portion and the convex portion of the hat-shaped connector.

In a preferred embodiment, the joint groove portion of the joint covering member is formed in a shape capable of covering the lower end surface of the upper outer wall panel in a state where the joint member and the upper and lower outer wall panels are attached, so that The seam covering member also has an upper edge portion extending upward from the upper end of the seam groove portion and pressed against the surface of the upper outer wall panel during construction, and an elastic water cut-off film is pasted on the back of the upper edge portion. pieces. In this aspect, the entire joint portion of the upper and lower outer wall panels can be covered with the joint covering material, and a good appearance in which the end faces of the outer wall panels are not exposed to the surface can be obtained. Wherein, in the outer wall construction structure using the seam of this form, in addition to the lower edge, the upper edge of the seam cover is also exposed in front of the outer wall, but the upper edge is different from the front of the front shown in Figure 8b. The face plate 63 is different, since it does not play the role of holding the end of the outer wall panel, so it can be formed with a small width and is not conspicuous.

In another preferred form, the seam groove portion of the seam covering member is formed to cover only the top surface of the convex portion of the hat-shaped connector when the seam member and the upper and lower outer wall panels are installed. and the shape of the upper end surface of the outer wall panel on the lower side, the joint covering member also has a protrusion extending from the end of the vertical plate of the joint groove to the back side, and the protrusion overlaps the joint during construction. The side surface of the upper side of the convex part of the hat-shaped connector. When installing the outer wall panels, sometimes there will be longitudinal seams formed along the vertical direction above the seams due to different positions, and the rainwater will flow to the seams through the longitudinal seams, but if the seams covered by this method Even if the above-mentioned longitudinal seam is a deep groove, the remaining rainwater can pass through the surface of the seam cover and flow further downward. That is, rainwater does not stay near the seam, and the water resistance is excellent.

Preferably, the cap-shaped connecting part and the seam covering part are each formed from a sheet steel sheet by sheet metal processing, which makes it easier to manufacture.

In yet another preferred aspect of the present invention, a part of the joint groove portion serves as a fixing surface fixed to the building frame side. The seam in this form is composed of a single member and has a simple shape, so it can be manufactured at a lower cost. It is more preferable to form the seam by sheet metal working of a sheet of steel, which makes manufacturing easier.

As described above, the seam material of the present invention is low in manufacturing cost, easy in construction, and can form a seam portion with high designability and high water-cutting performance.

The convex portion 12 is composed of upper and lower side surfaces 12a, 12b; and a top surface 12c connecting the upper and lower side surfaces 12a, 12b to each other. The intervals that are vacated are considerable distances. In addition, the upper and lower side end portions 11a, 11b of the substrate 11 are folded back on the front side in order to increase the strength.

Next, the seam cover material 20 is provided with the seam groove part 21 comprised from the vertical board 21a, and the upper board 21c and the lower board 21b extended from the upper and lower end parts to the surface side. The upper plate 21c and the lower plate 21b are separated by a slightly smaller width than the distance between the upper and lower sides 12a, 12b of the hat-shaped connector protrusion 12, so that the upper plate 21c and the lower plate 21b are easily inserted during construction. between the upper and lower outer wall panels 30A, 30B, and by slightly reducing the width of the seam to obtain a natural-looking seam appearance. The seam cover 20 further includes an upper edge portion 25 and a lower edge portion 23 respectively extending upward and downward from the upper end and the lower end of the seam groove portion 21 . The upper edge portion 25 and the lower edge portion 23 are located on the same plane, and the respective side end portions 25a, 23a are folded back toward the back side to increase strength. In addition, a plate-shaped elastic water cut-off member 26 made of EPDM rubber foam is attached to substantially the entire surface of the back surface of the upper edge portion 25 and the lower edge portion 23 .

When manufacturing the seam covering material 20, the seam groove part 21 is formed by bending a steel plate as a material in a U-shaped manner in cross section, and the front ends of the upper plate 21c and the lower plate 21b are bent upward and downward, respectively. Thus, the upper edge portion 25 and the lower edge portion 23 are formed. Also, the entire surface of the seam covering member 20 is painted in a desired seam color.

Next, an outer wall construction method using the above-mentioned joint material 1 will be described. First, after the upper end surface of the lower outer wall panel 30B is crimped to the lower side surface 12b of the hat connector protrusion 12, the outer wall panel 30B is superimposed from the upper surface of the base plate 11 at the bottom of the hat connector 10.
