This double-floor pillar structure is composed of a base part 101 placed on the floor surface 100, a cylindrical leg part 102 attached by riveting the lower end part at the approximate center of the base part 101, and a cylindrical leg part 102 formed on the base part 101. The male threaded portion 104 screwed with the female threaded portion 103 on the inner peripheral surface of the leg portion 102 is inserted into the leg portion 102 to freely adjust the height and position of the panel support bolt 105 and the head of the panel support bolt 105 A panel support member 106 mounted by end riveting, a panel fixing member 108 for fixing the floor panel 107 placed on the panel support member 106 to the panel support member 106 , a fixed panel support member 106 height position of the fixed operating lever 109 constitutes.

The base part 101 is manufactured as a flat plate in which a coating is applied to the surface of a substantially square steel plate. On the base portion 101, in order to stably place the pillar structure for a double floor on the floor surface 100, a substantially annular rib 110 protruding downward is formed to flatten the bottom surface (placement surface). In this base portion 101 , a substantially annular rib 110 formed at a position separated from the leg portion 102 and the lower end portion of the outer periphery are brought into contact with the floor surface 100 to support a pillar structure for a double floor.

The leg portion 102 is formed as a pillar in which a coating is applied to the surface of a cylindrical steel plate. The leg portion 102 is vertically fixed to the base portion 102 by inserting the lower end portion 102a into the hole portion 111 formed in the approximate center of the base portion 101, and riveting the lower end portion 102a to the outer peripheral portion of the hole portion 111. on the seat portion 101. On the inner surface of the leg portion 102, a female screw portion 103 is formed along the axial direction thereof. Moreover, the leg part 102 may be fixed to the base part 101 by welding.

The panel support bolt 105 has a male screw portion 104 on its outer peripheral surface that is screwed into the female screw portion 103 formed on the leg portion 102. By screwing the female screw portion 103 and the male screw portion 104, the Adjust the height position relative to the leg 102 accordingly. In addition, the panel supporting bolt 105 inserts the head end 105 a into the mounting hole 112 formed on the lower surface of the panel supporting member 106 , and caulks the head end 105 a to the outer peripheral edge of the mounting hole 112 . The panel support member 106 is fixed.

The panel support member 106 is formed of a disc-shaped body portion 114 having a panel mounting portion 113 on which the floor panel 107 is placed, and a cylindrical protruding portion 115 protruding upward from the center of the body portion 114 . The panel fixing member 106 is formed by coating the surface of a steel plate in the same manner as the front base portion 101 and leg portion 102 .

On the upper surface of the main body portion 114 is formed an engaging protrusion 117 formed in a low truncated circular shape that is inserted into and engaged with a positioning hole 116 formed on the lower surface of the floor panel 107 . The panel mounting part 113 is used as the upper surface of the main body part 114 except the engaging protrusion part 117, and places and supports the floor panel 107 by placing it under the floor panel. Furthermore, since four floor panels 107 are placed on this panel support member 106, the engaging protrusions 117 are formed at four positions.

On the protruding portion 115 , an engaging protrusion 119 is formed that engages with a hook portion 118 formed on the outer peripheral edge of the floor panel 107 . The engaging protrusion 119 is formed as an annular protrusion, and engages with the hooking portion 118 of the floor panel 107 whose head end is bent downward.

The panel fixing member 108 is composed of a panel pressing portion 120 and fastening bolts 123 . Among them, the panel pressing part 120 and the engaging protrusion 119 sandwich the hooking part 118 of the floor panel 107 and fix the floor panel 107 on the panel support member 106, and the fastening bolt 123 is on the outer periphery. On the surface is formed a male screw portion 122 that is screwed into the female screw portion 121 provided on the peripheral surface of the hole formed at the head end portion of the panel support bolt 105 facing the axial direction.

The panel pressing portion 120 is formed in a disk shape so that the lower end side outer peripheral surface 120 a contacts the hooking portion 118 to sandwich the hooking portion 118 from the vertical direction together with the engaging protrusion 119 . The fastening bolt 123 is inserted into a hole 124 formed through the center of the panel pressing portion 120 , and the male thread portion 122 is connected to the female thread portion 121 formed on the peripheral surface of the hole portion of the panel supporting bolt 105 . Screwed together, it can be freely attached to and detached from the panel support bolts 105 . A screwdriver groove 125 for screwing the panel pressing part 120 into the hole of the panel support bolt 105 with a screwdriver is formed at the proximal end of the fastening bolt 123 .

The fixing operation lever 109 is composed of a fixing part 127 having a female screw part 126 screwed with the male screw part 104 formed on the outer peripheral surface of the panel support bolt 105, and a handle having a slit 128 extending from the fixing part 127. Section 129 constitutes. The fixing operation lever 109 presses the fixing part 127 against the upper end surface of the leg part 102 by rotating the handle part 129, thereby reliably fixing the height position of the panel supporting member 106 temporarily positioned at a predetermined height, and making the panel The supporting member 106 is in a non-rotatable state.

Furthermore, the panel fixing member 108 and the fixing lever 109 are also formed by coating the surface of the steel plate in the same manner.

In order to form the double floor structure, first, the pillar structure for the double floor configured as described above is arranged on the floor surface 100 . Thereafter, the panel supporting member 106 is rotated so that the floor panel 107 is at a predetermined height H1 from the floor surface 100 . By rotating the panel support member 106 , the panel support bolt 105 is screwed into the female thread portion 103 and the male thread portion 104 of the leg portion 102 , and the height of the panel support member 106 is adjusted.

Then, in this state, since the panel support member 106 rotates relative to the leg portion 102, the handle portion 129 is rotated to lock the panel support member 106 in a non-rotatable state. When locking, as shown in FIG. 10 , the handle portion 129 is struck with a metal hammer 130 until deformed. In this way, the panel fixing member 106 is securely locked.

Thereafter, after the panel supporting member 106 has reached the predetermined height H1, the hooking portion 118 of the floor panel 107 is engaged with the engaging protrusion 119, and the engaging protrusion 117 is inserted into the floor panel 107. The positioning hole 116 below. At this time, the floor panel 107 is positioned on the panel mounting portion 113 of the panel support member 106 .

Then, the panel fixing member 108 is screwed into the panel supporting bolt 105 using a screwdriver or the like, and the panel pressing portion 120 is pushed against the hook portion 118 . At this time, since the hooking portion 118 is sandwiched between the engaging protrusion 119 and the panel pressing portion 120, the floor panel 107 is fixed without displacement.

By sequentially performing the above steps, a double-layer floor having an underfloor space between the floor surface 100 and the floor surface 100 can be constructed.

Patent Document 1: Japanese Unexamined Patent Publication No. 2000-87537 (pages 3 and 4, FIG. 1, FIG. 2 and FIG. 9)

Patent Document 2: JP-A-10-212817 (pages 3 and 4, FIG. 1, FIG. 6 and FIG. 9)

However, since the pillar structure for a double floor constructed as described above has a large number of parts, it takes a considerable amount of time and cost in an assembly process to perform riveting, welding, etc. of each part. In addition, since each component is formed by coating a steel sheet, an increase in cost cannot be avoided.

In addition, since the plating process is performed, it is difficult to avoid generation of whiskers (needle-shaped single crystals grown from plating films of low melting point metals such as Sn and Zn) or to contain hexavalent chromium. In addition, since each component is formed of a steel plate, in the load-bearing performance test of the panel/pillar assembly state, it is "total deformation = deformation of the floor panel + bending of the pillar", so the bending amount of the pillar In the case of a large steel pillar, the total bending amount tends to increase.

In addition, in this pillar structure for a double floor, the fixed operating rod 109 is used so that the panel supporting member 106 does not loosen, and since the fixed operating rod 109 is struck with a metal hammer 130, it is tightened with a constant tightening torque. Therefore, when the operating rod is tightened, a large metal percussion sound will be generated, resulting in noise.

In addition, in the pillar structure for a double floor, as shown in FIG. 9 , since the floor panel 107 is supported at a position away from the axis of the pillar (distance L1 from the center), the slab will be damaged by a slab. There is a tendency for the steps between panels to become large. In addition, since the leg portion 102 is fixed by riveting the base portion 101, it is difficult to ensure the perpendicularity between the base portion 101 and the leg portion 102. ladder.

In addition, in this double-floor pillar structure, an adhesive is applied on the lower surface of the base part 101 to fix it on the floor surface 100, but since the adhesive enters the ring formed on the lower surface of the base part 101 Since the thickness of the adhesive increases due to the recesses caused by the shaped ribs 110, the adhesive strength can be improved by applying it thinly and evenly, but the adhesive strength tends to be weakened. As a result, the effective bonding area decreases, and the bonding area has to be increased in order to increase the adhesive force.

Detailed ways

Hereinafter, specific embodiments using the present invention will be described in detail with reference to the drawings.

(Constitution of pillar structure for double floor)

Fig. 1 shows a front view of the pillar structure for a double floor according to this embodiment, Fig. 2 shows a pillar structure for a double floor according to this embodiment, (A) is a top view, (B) is a bottom view, and Fig. 3 is this embodiment Figure 4 shows the pillar base of the double floor pillar structure of this embodiment, (A) is a plan view, (B) is a front view, and Figure 5 is a pillar base of the double floor floor structure according to this embodiment. Longitudinal sectional view of a double-layered floor with a pillar structure supporting the floor panels.

As shown in FIGS. 1 to 3 , the pillar structure for a double-layer floor according to this embodiment consists of a pillar base 1 , a panel support member 2 mounted on the pillar base 1 , and a floor panel fixed to the panel support. The panel fixing member 3 on the member 2 and the fixing member 4 for fixing the height position of the panel support member 2 relative to the pillar base 1 are constituted.

"Pillar Base"

As shown in FIGS. 3 and 4 , the pillar base 1 is composed of a base portion 6 placed on the floor surface 5 , and leg portions 7 integrally erected on the base portion 6 . Such a base part 1 is integrally made of an aluminum die-cast with high mechanical strength.

As shown in FIG. 2(B), FIG. 3 and FIG. 4(B), the base portion 6 is formed in a square shape with a bottom surface 6 a substantially flat so as to be in stable close contact with the floor surface 5 . If the bottom surface 6a of the base portion 6 is made flat, the adhesive can be made thin and uniform, and thus the adhesive strength with the floor surface 5 can be greatly improved. On the contrary, in the conventional base portion 6 made of steel plate, since the annular rib is formed on the bottom surface 6a, the application thickness of the adhesive becomes thicker and the adhesive strength decreases. Therefore, in order to secure the adhesive It is necessary to increase the base portion 6 to increase the contact area. However, in the present embodiment, since sufficient joint strength can be secured with a base size smaller than conventional ones, cost reduction can be achieved.

In addition, the thickness of the base portion 6 gradually increases from the outer peripheral portion toward the leg portion 7 in order to increase the mechanical strength. In addition, each corner portion 8 of the base portion 6 has a rounded corner shape in which the corner portion is rounded into an arc shape. Thus, even if the pillar structure for a double floor is dropped to the floor surface (slab) 5 by mistake during the construction of laying the floor panels, it is possible to use the sufficient thickness and the rounded shape of the corner portion 8 to Prevent the pillar base 1 from being damaged.

In addition, in order to securely fix this double-floor pillar structure to the floor surface 5 , bolt insertion holes 9 through which bolts are inserted are formed in the base portion 6 . The bolt insertion hole 9 is formed as a circular hole penetrating through the vicinity of each corner portion 8 of the base portion 6 .

As shown in FIGS. 3 and 4 , the leg portion 7 is formed in a substantially cylindrical shape whose diameter gradually increases from the head end toward the base portion 6 , and is erected perpendicularly to the base portion 6 . Since the leg portion 7 is formed integrally with the base portion 6 by aluminum die-casting, it is not fixed by riveting or welding as in the past, and thus the standing angle with respect to the base portion 6 is kept constant. In this way, with the pillar structure for a double floor of this embodiment, it is possible to greatly reduce the steps generated between the floor panels that are supported.

In addition, a hole 10 into which the panel fixing member 3 is screwed is formed at the head end of the leg 7, and a female thread as a first screwing portion is formed on the inner peripheral surface of the hole 10. Section 11. In addition, on the outer peripheral surface of the head end side of the leg portion 7, a male screw portion 12 is formed as a second screwing portion for screwing the panel support member 2 to freely adjust the panel support. The installation height position of the component 2 relative to the pillar base 1 . On a part of the external thread portion 12, a flat surface 13 in which thread threads are cut and flattened is formed. The flat surfaces 13 are formed at two opposing positions, and function as tool pressing portions when the post base 1 is pressed with a tool when the fixing member 4 described later is rotated.

In addition, a plurality of ribs 14 for reinforcement are formed on the pillar base 1 from the leg portion 7 to the base portion 6 . Such ribs 14 are provided as substantially triangular flange portions inclined from approximately the central height position of the leg portion 7 toward the surface 6 b of the base portion 6 , and provided at positions that divide the leg portion 7 into four equal parts. By providing the ribs 14, the mechanical strength of the pillar base 1 can be greatly improved.

In the pillar base 1 in which the base portion 6 and the leg portion 7 are integrally formed by aluminum die-casting, since the diameter of the leg portion 7 is, for example, capable of withstanding a shock-resistant input acceleration of 1G, the thickness is gradually increased and in order to secure Since the base portion 6 has a minimum required area for adhesive strength, the amount of bending of the support base 1 can be greatly reduced compared to a conventional support made of a steel plate. For example, it is possible to improve the load resistance performance in the panel-pillar assembly state by about 30% or more. This makes it possible to reduce the thickness of the floor panels and thereby reduce the weight.

"Panel support member"

As shown in Figure 5, the panel support member 2 is screwed with the pillar base 1 to freely adjust its height position, and the floor panel 15 is placed and supported on a predetermined height H from the floor surface 5. By placing the floor panel The floor panel placing part 16 of 15 is constituted by the installation screwing part 17 integrated with the floor panel placing part 16 and screwed on the pillar base 1 . The panel support member 2 is integrally formed of an aluminum die-casting material having high mechanical strength, similarly to the pillar base 1 .

As shown in FIGS. 1 and 2 , the floor panel placing part 16 is composed of a main body part 18 , and four panel mounting parts 19 protruding from the upper surface of the main body part 18 , and are located between these panel mounting parts 19 . The panel auxiliary support member 20 as the upper surface of the main body portion 18 is constituted.

The main body part 18 is formed as a substantially disc body with four positions on the outer peripheral surface being straight lines, the panel mounting part 19 is formed on the upper side, and the mounting screw part 17 is formed on the lower side.

The panel mounting portions 19 are provided corresponding to four positions where the outer peripheral surface of the main body portion 18 is linear, and are formed as substantially rectangular protrusions. In addition, the four panel mounting portions 19 are connected and integrated by the annular wall portion 22 surrounding the through hole 21 in which the leg portion 7 is formed at the center of the panel support member 2 . The panel mounting portion 19 is formed as a raised portion higher than the annular wall portion 22 by one step, and the upper surface formed as a flat surface serves as a panel placement surface 23 for placing the corner portion of the floor panel 15 .

On this panel placement surface 23, a buffer rubber 24 as a buffer member made of rubber or the like is attached. The cushion rubber 24 functions as a cushioning material between the floor panel 15 and the double-floor pillar structure, prevents metal-to-metal contact noise, and moderates echoes generated when walking on the floor panel 15 . In addition, this buffer rubber 24 prevents corrosion of the floor panel 15 made of galvanized steel sheet and the panel support member 2 made of aluminum die-casting due to dissimilar metal contact.

In addition, the inner surface 19a of the panel mounting portion 19 is formed into an arc shape corresponding to the shape of the corner portion of the floor panel 15, and is formed from the panel placement surface 23 to the upper surface 22a of the annular wall portion 22. Inclined slope. In the space formed by the inner surface 19a of the panel mounting portion 19 and the upper surface 22a of the annular wall portion 22, the hook portion 25 formed by bending the corner portion of the floor panel 15 downward is arranged. . The hooking portion 25 disposed in the space portion engages with the stepped portion 28 forming the panel mounting portion 19 . The stepped portion 28 functions as a main panel support portion on which the hook portion 25 of the floor panel 15 is placed.

In addition, on the inner surface 19a of the panel mounting portion 19, a panel displacement prevention protrusion 26 for preventing displacement of the floor panel 15 in the horizontal direction is formed. This kind of panel misalignment preventing protrusion 26 is made to a height slightly protruding from the height of the buffer rubber 24 provided on the panel placement surface 23, and the floor panel 15 is used to prevent the floor from being stuck in contact with the hook portion 25 of the floor panel 15. Misalignment of plate 15.

Further, on the outer surface of the panel placement portion 19 , a U-shaped vertical groove 27 in plan view is formed at a position extending downward from the panel placement surface 23 to the front of the connecting portion with the main body portion 18 .

The auxiliary panel support portion 20 is formed as a part of the main body portion 18 forming a sector between the respective panel mounting portions 19 . The panel auxiliary support portion 20 has a certain gap S (see FIG. 5 ) with respect to the corner underside 15a of the floor panel 15, and supports the corner underside 15a of the floor panel 15 near the final load. In this way, since the floor panel 15 is mainly used, the floor panel 15 is placed on the panel placement surface 23 by being hooked by the step portion 28 , and the corners of the floor panel 15 are supported by the panel auxiliary support portion 20 . The lower surface 15a therefore prevents damage to the corner portion of the floor panel 15 even when a load is applied locally due to repeated movement of the trolley, for example.

In addition, the floor panel 15 is placed on the panel placement surface 23 to hook the hook portion 25 and the stepped portion 28, and is fixed by pinching the hook portion 25 together with the panel fixing member 3 described later. Therefore, the construction speed of laying the floor panel 15 can be accelerated. In the conventional bottom support structure supporting the lower surface (bottom surface) of the floor panel 15, it was necessary to tighten the fixing lever to a predetermined torque, but this structure does not require it.

Moreover, since it is a flange support structure, the step|step difference between the adjacent panels placed in each panel mounting part 19 produces only the difference of the board|board thickness of the floor panel 15. FIG. In the conventional bottom support structure, a step is directly caused by the overall thickness of the floor panel 15 . In particular, since the thickness of the floor panel 15 tends to be uneven, it is easy to form a step in the conventional structure, but it is difficult to form a step in the present structure. Furthermore, when 3000N panels and 5000N panels with different plate thicknesses are adjacent to each other, by inserting a space corresponding to the difference in plate thickness between the panel placement surface 23 and the buffer rubber 24, these panels can be easily made. The boards become the same plane.

The attachment screwing portion 17 is formed in a cylindrical shape at the center of the lower surface of the panel support member 2 . On the inner surface of the mounting screwing portion 17, a female screw portion 35 as a third screwing portion is formed, and the female screw portion 35 is screwed with the male screw portion 12 formed on the outer peripheral surface of the leg portion 7 and freely adjusted. The height position relative to the pillar base 1. By screwing the female screw portion 35 of the attachment screwing portion 17 and the male screw portion 12 of the leg portion 7, the panel support member 2 can be adjusted to a desired height position with respect to the pillar base 1 .

"Panel Fixing Components"

The panel fixing member 3 is composed of a panel pressing part 29 and a fixing bolt 30 as a fourth screwed part as shown in FIGS. 25 is clamped between the stepped portion 28 of the panel mounting portion 19, and the fixing bolt 30 is inserted into the hole 10 formed at the head end of the leg portion 7, and screwed with the female thread portion 11 to adjust the panel The height position of the pressing part 29.

The panel pressing portion 29 is formed as a disc body having a hooking portion pressing surface 29 a for pressing the hooking portion 25 of the floor panel 15 at the lower end. The panel pressing portion 29 sandwiches the hook portion 25 together with the stepped portion 28 from the vertical direction to sandwich the hook portion 25 . Thus, at the center of the panel pressing portion 29, a through hole 31 through which the fixing bolt 30 is inserted is formed.

The fixing bolt 30 is inserted into the hole 10 formed at the head end of the leg 7 , and the male screw 32 formed on the outer peripheral surface thereof is screwed into the female screw 11 of the hole 10 . When the fixing bolt 30 is rotated in the tightening direction, the panel fixing member 3 is screwed in toward the panel supporting member 2 side, and together with the panel pressing portion 29 clamps the panel mounted on the stepped portion 28 . Hook up part 25. Conversely, when the fixing bolt 30 is rotated in the loosening direction, the bolt fixing member 3 rises away from the panel supporting member 2 , and the clamped state of the hook portion 25 is released. Further, at the proximal end of the fixing bolt 30, a disc-shaped screw head 34 having a cross-shaped screwdriver groove 33 for screwing the fixing bolt 30 with, for example, a screwdriver is formed.

In this way, if the fixing bolt 30 is screwed to the female screw portion 11 formed at the head end of the pillar base 1 integrated with aluminum die-casting, since the pillar base 1 is very firm, it can be fixed without shaking. Securely fix the floor panel 15 .

"fixed components"

As shown in FIGS. 1 and 2 , the fixing member 4 is a member that fixes the height position of the panel support member 2 relative to the pillar base 1, and is screwed with the male screw portion 12 formed on the outer peripheral surface of the leg portion 7. The fixing part 37 of the internal thread part 36 which is the fifth screwing part, and the operation lever part 38 formed extending from the fixing part 37 are constituted.

Such a fixing member 4 puts the panel supporting member 2 in a non-rotatable locked state by press-contacting the fixing portion 37 with the lower end portion of the panel supporting member 2 , wherein the panel supporting member 2 is locked by rotating the operating lever portion 38 . Temporarily maintained at the specified height. In this way, the panel support member 2 can be reliably held at a predetermined height position. The operation of rotating the operation lever portion 38 of the fixing member 4 does not require a special tool, and can be easily operated by hand (finger). Thereby, since there is no need to hit the operation lever portion 38 with a metal hammer during construction, quiet construction can be performed without generating sound. Therefore, there is no disturbance to on-site operators or people close to the site.

"How to Lay Floor Panels"

Next, the construction method of laying the floor panel 15 using the pillar structure for double floors comprised as mentioned above is demonstrated. The construction process here is an example, and the order of the following steps may be changed to a certain extent regarding the order.

First, the double-floor pillar structure configured as described above is placed on the floor surface 5 .

In addition, in the pillar structure for a double floor according to the present embodiment, since the bottom surface 6a of the base portion 6 is formed as a substantially flat surface in close contact with the floor surface 5, the adhesive can be applied thinly and uniformly, thereby The bonding strength with the floor surface 5 can be greatly improved.

In addition, in the double-floor pillar structure of this embodiment, since the thickness of the base portion 6 is gradually increased as it approaches the leg portion 7 from the outer peripheral portion, the strength against horizontal loads caused by earthquakes and the like can be increased. , so that the mechanical strength of the pillar base 1 supporting the floor panel 15 can be improved.

In addition, in the pillar structure for a double floor according to the present embodiment, since the leg portion 7 is made into a substantially cylindrical body whose diameter gradually increases as it advances from the head end to the base portion 6, it is relatively heavy in terms of buckling load. Strong, hard to buckle. In addition, since the leg portion 7 has a hollow structure, a long adjustment amount can be ensured.

In addition, in the pillar structure for a double floor according to the present embodiment, since the reinforcing rib 14 is formed from the leg portion 7 to the base portion 6, the mechanical strength of the pillar base 1 is greatly improved, thereby improving the load-bearing performance. . In addition, since the base portion 6 and the leg portion 7 are integrated, the mechanical strength of the pillar base 1 can be further improved. As a result, since the strength of the pillar base 1 is improved, the thickness and weight of the floor panel 15 can be reduced.

In addition, in the double-floor pillar structure of this embodiment, since at least the pillar base 1 and the panel support member 2 are made of aluminum die-casting that does not require surface treatment and does not generate rust, it is possible to avoid damage to the pillar structure. Whiskers or hexavalent chromium generated by coating a conventional steel sheet.

In addition, in the pillar structure for double floors of the present embodiment, since the hooking portion 25 and the stepped portion 28 of the floor panel 15 are hooked and placed on the panel placement surface 23, the panels of the panel fixing member 3 Since the pressing part 29 clamps and fixes the flange support structure of the hook part 25 together, it does not support the bottom surface of the panel as in the conventional structure, so only a difference in the thickness of the panel occurs, and the steps between the panels can be reduced.

In addition, since the pillar structure for double floors of this embodiment is a flange support structure, the horizontal distance L (see FIG. 5 ) from the pillar axis to the position where the floor panel 15 is placed can be shortened, thereby Significantly reduce the moment applied to the pillar base 1.
