Here, for example, a building used for a limited-time event or the like is temporarily constructed and then relocated, and finally, a building is considered to be built by a full-scale construction method (main construction). However, none of the above references are useful in this regard.

In view of the above circumstances, it is an object of the present invention to provide a floor panel structure capable of easily constructing a temporary floor by a dry type, and to provide a dry floor structure using the floor panel structure.

The floor panel structure of the present invention is a floor panel structure constituting a dry floor of a building, in which a corrugated material having a wavy shape intersects with a corrugated material in the longitudinal direction in the ridge line direction of the corrugated material and is spaced in the ridge line direction. It is characterized by having a plurality of crosspiece members fixed to the corrugated material and a horizontal brace connecting adjacent crosspiece members.

In the above configuration, the plurality of crosspiece members are fixed to the corrugated material by crossing their longitudinal directions in the ridge line direction, so that the deformation of the corrugated material is suppressed, and thus the floor panel structure is formed. Can be joined to the building frame as a dry floor using a fastening member, and even when dismantling, the floor panel configuration can be easily removed from the frame by loosening the fastening member. Become. That is, this floor panel structure can be easily constructed as a temporary floor, and can be independently removed without damaging the building frame. In addition, since this floor panel structure does not have a frame, it is lightweight, and the work load of attaching the floor panel structure to the building frame can be reduced, and the cost can be reduced by reducing the materials. Can be planned.

The corrugated material may be formed by two or more partial corrugated materials having different wave periods. Here, when only one type of corrugated material with a period is used, the bottom of the corrugated material may not be fixed on the end end side of the crosspiece member due to the width dimension of the product of the corrugated material. In addition, such inconvenience can be eliminated by using partial corrugated materials having different wave periods from each other.

One of the partial corrugated materials having different wave periods has a hat shape having one convex portion, and may be provided on the central side or the end side in the longitudinal direction of the crosspiece member.

At the end of the crosspiece member, a horizontally arranged joining plate to be joined to the horizontal plane portion on the skeleton side of the building may be provided. According to this, since the floor panel structure is joined to the horizontal surface portion on the skeleton side of the building by the horizontally arranged joint plate, the horizontal load is efficiently applied between the floor panel structure and the skeleton. Can be communicated.

A part of the joining plate protrudes horizontally from the edge of the corrugated material, and this protruding portion may be a mounting place of the fastening member with respect to the skeleton side. According to this, since the mounting portion of the fastening member is not hidden by the corrugated material, the work of joining the floor panel structure to the skeleton side becomes easy.

A plate member vertically arranged parallel to the longitudinal direction is provided at the end portion of the crosspiece member in the longitudinal direction, and the joint plate is formed on the lower end surface of the plate member and the lower surface portion of the end portion of the crosspiece member. It may be fixed to. According to this, the vertically arranged plate members reinforce the vertical load applied to the joint plate.

Further, the dry floor structure of the present invention is characterized in that the floor panel structure is detachably fixed to the side of the building frame. According to this, the floor panel structure can be removed independently from the building, and it becomes easy to provide a full-scale floor on the skeleton from which the floor panel structure is removed and to install the floor panel structure. Further, a plurality of floor panel configurations having a common structure can be arranged to form a dry floor.

In the dry floor structure, the thickness of the crosspiece member may be thinner than that of the beam of the beam that is the frame of the building. According to this, a space can be formed on the side of the beam on the lower side of the floor panel structure, and it is possible to arrange pipes and the like by using this space.

Further, the method for manufacturing a dry floor structure of the present invention is characterized in that the floor panel structure is manufactured at a factory, transported to a construction site, and detachably fixed to the side of the building frame by a fastening member. do.

According to the present invention, while it can function as a floor of a building that is temporarily built, it can be removed independently from the building frame, making it easy to build in earnest.

Hereinafter, embodiments according to one aspect of the present invention will be described with reference to the accompanying drawings. As shown in FIGS. 1A and 1B, the floor panel structure 1 of this embodiment is formed in a rectangular shape and has a ridge line (flow direction) in the long side direction of the rectangular shape. A deck plate (corrugated material) 11 arranged horizontally, a horizontal brace 12 receiving a horizontal load, joint plates 13A and 13B arranged horizontally, and a plurality of crosspiece members 14 arranged horizontally are provided. , It is possible to construct a dry floor of a building. Here, in order to construct a drywall, there is a problem that a mechanism capable of transmitting a horizontal load is required, the number of members increases, and the labor of construction increases, and this embodiment also solves this problem. Plan.

The crosspiece member 14 is made of, for example, a square steel pipe having a closed cross section. Further, the crosspiece members 14 have their longitudinal directions orthogonal to the ridgeline direction of the deck plate 11, and are arranged parallel to each other at predetermined intervals in the ridgeline direction. The valley bottom portion of the deck plate 11 is in contact with the upper surface of the crosspiece member 14, and the deck plate 11 and the crosspiece member 14 are mutually fixed by screwing a drill screw (not shown) at this contact point. ing.

Further, as shown in FIG. 2A, a first plate member 141 is welded and fixed to the end portion of each crosspiece member 14 in the longitudinal direction so as to close the opening of the end surface of the end portion. The second plate material 142 is welded to the first plate material 141 so as to form a substantially T-shape (parallel to the longitudinal direction) in a plan view with respect to the first plate material 141. It is fixed. Further, the edge (valley bottom edge) of the deck plate 11 is located at the end portion of the crosspiece member 14 in the longitudinal direction.

The joint plate 13A is welded and fixed to the lower surface of each crosspiece member 14 on the central side on the end side in the longitudinal direction, and the joint plate 13B is attached to the lower surface on the end side of each crosspiece member 14 on both ends in the longitudinal direction. It is fixed by welding. Further, the lower end portion of the second plate member 142 is welded and fixed to the upper surfaces of the joining plates 13A and 13B. Further, the horizontal braces 12 are arranged between the crosspiece members 14, and the ends of the horizontal braces 12 are fixed to the joint plates 13A and 13B by bolts and nuts (not shown).

Further, as shown in FIGS. 2B and 2C, a part of the joining plates 13A and 13B protrudes horizontally from the edge of the deck plate 11. Insertion holes 131 for mounting fastening members (bolts and nuts) are formed at both sides of the second plate member 142 in the protruding portion. At the factory shipment stage of the floor panel structure 1, a wooden board made of plywood or the like may be fixed on the deck plate 11 with screws or the like, or the wooden board may be fixed to the deck at the site. It can also be fastened to the plate 11.

The floor panel structure 1 is arranged between, for example, H steel beams (including a trunk difference) 2 and 2, which are the frame of the building. A hole 142a is formed in the second plate 142, and the hanging metal fitting at the tip of the wire is locked in the hole 142a, and the wire is pulled up by a crane to lift the floor panel structure 1. be able to.

A plate-shaped skeleton-side member (horizontal plane portion on the skeleton side of a building) 21 protruding in the horizontal direction is welded and fixed to the web of the H-steel beam 2. The skeleton side member 21 is formed with an insertion hole 21a at a position corresponding to the insertion hole 131, as shown in FIGS. 3 and 4. Then, by attaching a fastening member to the insertion hole 21a and the insertion hole 131 of the skeleton side member 21 and tightening the fastening member, the floor panel structure 1 can be detachably fixed to the skeleton side member 21. .. The width of the deck plate 11 in the floor panel structure 1 is shorter than the distance between the beams of the H steel beams 2 and 2, and is between the edge of the deck plate 11 (valley bottom edge) and the edge of the H steel beam 2. A gap is formed in. Using this gap as a work space, the work of joining the floor panel structure 1 to the H steel beam 2 can be performed. For example, the operator passes a bolt through the insertion hole 21a of the skeleton side member 21 and the insertion hole 131 of the joining plates 13A and 13B while riding on the deck plate 11, and screwes a nut into the bolt. Can be fixed.

The skeleton side member 21 projects long beyond the protruding length of the flange of the H steel beam 2, and the joining plates 13A and 13B can be placed on the tip end side of the protruding region. When the fastening member is tightened in such a state, the joining plates 13A and 13B are fixed to the skeleton side member 21 in a surface-joined state.

The arrangement height of the skeleton side member 21 is such that the upper surface of the crosspiece member 14 is substantially flush with the upper surface of the upper flange of the H steel beam 2 with the floor panel structure 1 attached. ing. Further, the thickness of the crosspiece member 14 is made thinner than that of the beam of the H steel beam 2 of the building so that a space is formed under the floor panel structure 1 between the H steel beams 2 and 2. It has become.

Further, on the lower side of the skeleton side member 21, a vertically arranged reinforcing plate 22 orthogonal to the skeleton side member 21 and also orthogonal to the web of the H steel beam 2 is provided. The reinforcing plate 22 is welded and fixed to the lower surface of the skeleton side member 21, the web of the H steel beam 2, and the upper surface of the lower flange.

In the floor panel structure 1, since the plurality of crosspiece members 14 are fixed to the deck plate 11 with their longitudinal directions intersecting the ridgeline direction, deformation of the deck plate 11 is suppressed. The floor panel structure 1 can be used as a dry floor and joined to the building frame (H steel beam 2, etc.) using fastening members (bolts, nuts, etc.), and the fastening members can be loosened during dismantling. Therefore, the floor panel structure 1 can be easily removed from the skeleton. That is, the floor panel structure 1 can easily construct a temporary floor, and can be independently removed without damaging the building frame. Further, since the floor panel structure 1 does not have a frame-like body, it is lightweight, and the work load of attaching the floor panel structure 1 to the building frame can be reduced, and the cost can be reduced by reducing the materials. be able to.

Further, as described above, when the joining plates 13A and 13B to be joined to the skeleton side member 21 are provided in a horizontal arrangement, the floor panel configuration 1 is described by the horizontally arranged joining plates 13A and 13B. Since it is joined to the skeleton side member 21, the horizontal load can be efficiently transmitted between the floor panel structure 1 and the H steel beam 2. In particular, when the horizontal brace 12 is connected to the horizontally arranged joint plates 13A and 13B, the transmission of the horizontal load becomes more efficient.

Further, a part of the joining plates 13A and 13B protrudes horizontally from the edge of the deck plate 11, and the protruding portion is a place where the fastening member (bolt, nut, etc.) is attached to the skeleton side member 21. Then, since the mounting location of the fastening member is not hidden by the deck plate 11, the work of joining the joining plates 13A and 13B of the floor panel structure 1 to the skeleton side member 21 becomes easy.

Further, as described above, when the floor panel structure 1 is detachably fixed to the side of the building frame, the floor panel structure 1 can be removed independently from the building, and this floor panel structure can be removed. It becomes easy to provide a full-scale floor on the skeleton from which the body 1 has been removed and to install the main body.

Further, the thickness of the crosspiece member 14 is made thinner than that of the beam of the H steel beam 2 of the building, and a space is formed under the floor panel structure 1 in the space between the beams of the H steel beam 2. If this is possible, it will be possible to arrange pipes and the like using this space.

Further, as described above, if the floor panel structure 1 is manufactured at a factory, transported to a construction site, and joined to the building frame, the floor panel structure 1 is manufactured at the factory. Therefore, it is possible to accurately assemble the floor panel structure 1 whose dimensions are as designed. The floor panel structure 1 is not limited to being manufactured at a factory, and may be manufactured on the ground or the like at the site.

Further, in the reuse of the skeleton of the building, the skeleton from which the floor panel structure 1 is removed in the building having the dry floor structure can be reused to build the building. Then, in this reuse, for example, a deck plate is newly provided on the upper flange of the H steel beam 2 from which the floor panel structure 1 is removed, and concrete is poured on the deck plate to form a deck concrete floor. Can be made.

Further, as described above, when the floor panel structure 1 is removed from the building frame side member 21 and the deck plate is fixed on the H steel beam 2 to form a deck concrete floor, the floor panel structure 1 is used. It is also possible to reuse the deck plate 11.

Further, the deck concrete floor can be manufactured in the reuse without removing the skeleton side member 21. That is, in the method of reusing the building skeleton using the floor structure, it is not necessary to remove the skeleton side member 21 that supports the floor panel structure 1, and damage to the skeleton can be prevented when the skeleton side member 21 is removed. .. Although C-shaped steel can be used as the beam, it can be said that it is desirable to use H-shaped steel in consideration of such skeleton reuse.

Further, the corrugated material may be formed of two (or two or more) partial corrugated materials having different wave periods. In the example shown in FIG. 5, the deck plate 11 is used as one partial corrugated material, and the hat-shaped plate 11A having one convex portion in the substantially rectangular corrugated plate is used as the other partial corrugated material. The hat-shaped plate 11A is provided on the end side of the crosspiece member 14 in the longitudinal direction. The hat-shaped plate 11A has bottom plate portions on both sides of the one convex portion, and the bottom plate portions are fixed to the top surface of the crosspiece member 14 by a drill screw or the like (not shown). Alternatively, as shown in FIG. 6, two deck plates 11 are arranged on the end side in the longitudinal direction of the crosspiece member 14 as one partial corrugated material, and the hat-shaped plate 11A is placed on the longitudinal direction of the crosspiece member 14. It may be provided on the center side. Here, when only one type of corrugated material with a period is used, the bottom of the corrugated material may not be fixed on the end end side of the crosspiece member 14 due to the width dimension of the product of the corrugated material. As described above, such inconvenience can be eliminated by using partial corrugated materials having different wave periods from each other.

The floor panel of the present application is a semi-finished product in which the deck plate 11 is not mounted and only the hat-shaped plate 11A is mounted, or a semi-finished product in which the deck plate 11 is mounted and the hat-shaped plate 11A is not mounted. It can also be shipped from the factory as a component. That is, if the crosspiece member is provided with the corrugated sheet material, the floor panel structure of the present application includes the corrugated sheet material even if the width of the corrugated sheet member is less than the total width of the crosspiece member 14. Then, at the site, the deck plate 11 for additional mounting or the hat-shaped plate 11A for additional mounting may be mounted at the site. Further, at this time, another deck plate or a substantially rectangular corrugated plate may be provided so as to straddle the H steel beam 2.

Although the embodiment of the present invention has been described above with reference to the drawings, the present invention is not limited to that of the illustrated embodiment. It is possible to make various modifications and modifications to the illustrated embodiment within the same range as the present invention or within the same range.
