Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a floor structure in an industrialized house built by combining a plurality of housing units.

[Background technology]

Currently, industrialized housing is widely used, which is constructed using the unit construction method in which multiple box-shaped housing units prefabricated at a factory are assembled at the construction site. It is constructed by connecting the upper and lower ends of the structure with metal beams.

When installing a floor in the above-mentioned industrialized housing, a surface material serving as a floor is placed at the bottom of each housing unit, but conventionally, this surface material was placed in the lower part of each housing unit. It has a length that reaches the beam on the lower side where the knit floor is installed, and this facing material made of particle board or the like is fixed to the metal beam by nailing with a nailing device.

[Problem to be solved by the invention]

However, even if you use a nailing device, the beams are made of metal, so nailing may not always be possible reliably.
In particular, as thicker beams are used to increase the strength and rigidity of housing units, nailing work has become increasingly difficult.

In addition, connecting panels are placed between housing units to connect the walls of each housing unit, but in the past, the panels of each housing unit had a length that reached the beams of the housing units as described above. , this connecting panel is small and has a width up to the beam of each housing unit. Therefore, if there is a vertical difference between adjacent housing units due to housing unit installation errors, etc., the connecting panel will be tilted at a relatively large angle, resulting in the problem that subsequent floor finishing operations will be troublesome.

The purpose of the present invention is to make it possible to easily perform the nailing work for fixing the surface of the floor to the housing unit 1, and to make it possible to easily perform the nailing work for fixing the floor surface to the housing unit 1. The purpose of the present invention is to provide a floor structure for an industrialized house that can reduce the inclination of a connecting surface material that connects the surface materials.

[Means for Solving the Problems] The floor structure of the industrialized housing according to the present invention includes a box-shaped housing unit whose frame is made by connecting the upper and lower ends of four metal columns with metal beams. In industrialized housing that is built by combining multiple units, a wooden support member is placed inside the lower beam where the floor of the housing unit will be installed, parallel to this beam, and the surface material that will become the floor is placed up to this support member. It is characterized by its length, and the connecting face material placed between housing units reaches the receiving material of each housing unit.

[Effect]

The facing material and the connecting facing material are fixed to the receiving material by nailing, and since this receiving material is made of wood, nailing work can be easily performed.

In addition, since the support material is placed inside the beam of the housing unit, the connecting surface material that is placed between the housing units and reaches this support material has a large width dimension. Even if there is, the inclination angle of the connecting face material will be small.

Further, a receiving member 12 parallel to the beam 5 is arranged inside the beam 5 and connected to the end of the joist 9.

Further, a receiving member l3 is arranged inside the beam 4 and is connected to the beam 4, and two connecting members 14 are each spanned between the receiving member 13 and the field edges 7 at both ends.

The receiving material 11 is for attaching a floor surface material together with the beam 5.6 and the joist 9, which are floor beams, and the receiving material 13 is
This is for attaching a ceiling surface together with the beams 3 and 4 that are ceiling beams and the roof edge 7.

Figures 3 and 4 are cross-sectional views taken along lines IV--IV and ■■ in Figure 2 with the floor material installed, and Figures 6 and 7 are cross-sectional views taken along lines ■--■ in Figure 5, It is a sectional view taken along the line ■-■. As shown in these figures, the pillar 2 is made of a metal square pipe, and the beams 3 to 6 are made of metal channel material. On the other hand, the supporting materials 11 to 13 are made of wood, as are the roof edge 7 and the joists 9.

As shown in FIG. 2 and FIG.
are connected via the same bracket 17. The specific shape of this bracket 17 is shown in FIG. The braget 17 has upper and lower horizontal flanges 18.19 and a vertical extension 20 extending forward from these flanges 18.19. The base has an extension part 20 made by extrusion press processing.
A rib portion 21 protruding in the thickness direction is provided, and the stiffness of the brackets 1 and 2l is increased by the reinforcing effect of this rib portion 21. The extension part 20 has a lower side 2OA horizontal and an upper side 20
B has a substantially triangular shape with a downward slope toward the front, and holes 22 to 26 are formed in the extending portion 20. The hole 22 is formed at the forefront, the hole 23.24 is formed at the middle portion, and the hole 25g26 is formed at the rearmost portion, and the holes 23, 24, and holes 25, 26 are formed apart in the vertical direction. There is.

As shown in FIGS. 3 and 6, the above-mentioned bracket 17 has upper and lower flange portions 18, 19 made of channel material.
By spot welding the upper and lower inner surfaces of beam 3.5
By selectively inserting wood screws 27, which are connectors, into three of the holes 22 to 26 of the extension part 20, the field edge 7 and the joists 9 are joined to the extension part 20. .

Specifically, as shown in FIG. 3, the floor joists 9 have large vertical dimensions so as to be able to withstand large loads acting on the joists 9, and their ends are inserted into the beams 9. , hole 2
Joists 9 are connected by inserting wood screws 27 into holes 22, 25, and 26 that have the largest distance in the vertical and longitudinal directions among holes 2 to 26. On the other hand, as shown in FIG. 6, the ceiling edge 7 on which such a large load does not act has a small vertical dimension, and its end is not inserted into the beam 3, so the vertical direction of the holes 22 to 26 is , wood screws 27 are inserted into the holes 22, 23, and 24 having the smallest separation distance in the front-rear direction to connect the field edges 7.

As a result, the roof edge 7 and the joist 9 are connected to the beam 3.5 using the same bracket 17.

Further, as shown in FIGS. 2 and 4, a connecting member 10 to the beam 6
The connection is also performed using the bracket 17. The connecting member 10 is connected to the joist 9 using a bracket 28, and the specific shape of this bracket 28 is shown in FIG. Bracket 2nd is left and right flange part 29.3
It has protrusions 31 and 32 protruding forward from 0, and these protrusions 3'l and 32 are connected by a connecting part 33 at the lower end,
As shown in FIG. 4, the wood screws 17 are inserted into the holes 34 formed in the flanges 29, 30 and the protrusions 31', 32 to connect the joists 9 and the connecting members IO.

In addition, as shown in FIGS. 5 and 7, the field edge 7 and the connecting member 14 are
The bracket 28 also connects the receiving member 13 and the connecting member 14.

As shown in FIGS. 3 and 4, the receiving members 11 and 12 are the connecting members 10,
It is placed on the notches 10A and 9A of the joists 9, and as shown in FIG. It is fixed to the joint hardware 16. Furthermore, as shown in FIG. 5, the support material 3 is connected to the beam 4 via a bracket 37, and the end of this support material 13 is fixed to a bracket 39 connected to the column 2 via a connecting hardware 38. .

With the above structure, the beams 3 and 5 are connected to the beams 7 and the joists 9 that are perpendicular to the beams 3 and 5, so even if the beams 3 and 5 are made of channel material, they are not beams. 3,5
has great torsional rigidity. In addition, the beams 4 and 6 also have connecting members 10.
Since the beams 14 are connected, even if the beams 4 and 6 are made of channel material, the beams 4 and 6 have great stiffness against torsion. Therefore, due to these factors, the housing unit 1 as a whole has a structure that is resistant to lateral buckling.

As shown in Figures 3 and 4. A surface material 40 made of particle board or the like is arranged on the upper surface of the joist 9 to serve as a floor.

The length of this face material 40 in the left-right direction and front-back direction is the length of the receiving material 11
．． 12 and shall not reach beams 6 and 5. The facing material 40 is fixed to the joist 9 and the support material 11.12 by gluing and nailing. Such a facing material 40 is provided for adjacent housing units 1, and is provided for adjacent housing units 1.
Connecting face members 41, 42 are arranged between them. These connecting panels 41 and 42 have a relatively large width that reaches the receiving members 11 and 12 of each housing unit 1. These materials 41 and 42 are also receiving materials II.
, 12 by gluing and nailing.

After this, finishing materials are placed on the upper surfaces of the facing material 40 and the connecting surfaces IJ'41 and 42, and the floor is finished.

Furthermore, a panel material that will become a ceiling is fixed to the lower surfaces of the field edge 7 and the receiving shrine 13 by adhesive and nailing, and a finishing material is attached to this panel material to complete the ceiling.

According to the present embodiment described above, the face material 40, the connecting face material 41.
Since the nailing for 42 is performed not on the metal beam 56 but on the wooden supports 11 and 12, even if the thickness of the beams 5 and 6 is increased to increase the rigidity of the housing unit, this Nailing work becomes easier. Also,
The connecting faces 41 and 42 have a large width that reaches the receiving members 11 and 12 of each housing unit 1, so even if the adjacent housing units 1
Even if there is a difference in level between the top and bottom, the connection surface +, 14 1.
, 4 2 becomes small, and as a result, a good floor finish can be achieved. In addition, Figures 3 and 4
As shown in the figure, the connecting panels 41 and 42 and the beam 5,
By providing gaps S, S2 between the connecting faces 41 and 6, interference with the beam 56 can be prevented even if the connecting face members 41 and 42 are tilted.

In addition, the receiving members 11.12 are the same as the joists 9, and although they are members for attaching the facing material 40 and the connecting facing material 41.42, these receiving materials 11, 1.2 are not connected. Since the material 10 is placed on and supported by the joist 9, the cross-sectional area can be smaller than that of the joist 9. Furthermore, if the dimensions between the receiving members 11 and 12 of adjacent housing units 1 are set based on the module that defines the dimensions of the housing unit 1, the manufacturing of the connecting panels 41 and 42 can be simplified. There is no wastage of materials and it can be done easily.

In addition to the above, according to this embodiment, when connecting the field It 7 to the beam 3 serving as a ceiling beam, and when connecting the joist 9 to the beam 5 serving as a floor beam, these l1 etc. As described above, since the connection is performed using the bracket 17 in which the holes 22 to 26 are provided separately in the vertical and front-back directions in the extension part 20, the vertical dimensions, etc. of the field edge 7 and the joist 9 are different. However, by selectively inserting the wood brackets 27, which are connectors, into the holes 22 to 26, the same brackets 17 can be used to connect the beam 3 and the roof edge 7, and to connect the beam 5 and the joist 9. It becomes possible to perform the combination of , and it is possible to achieve the commonization of Brakent 17.

In the embodiment described above, the receiving member 11 is supported by the connecting member 10 and placed inside the beam 6, but the connecting member 10 does not necessarily need to be provided. Further, the connection between the joist 9 and the beam 5 is not limited to the structure shown in this embodiment, and the present invention can be applied to cases where other connection structures are adopted.

〔Effect of the invention〕

According to the present invention, wooden support members are arranged inside the lower beams on which the floor of the housing unit is installed, so that it is possible to easily nail the surface material that will become the floor. Even if there is a level difference between the top and bottom of the housing units, the width of the connecting panels that connect the panels of each housing unit is relatively large enough to reach the receiving members of each housing unit, so the inclination of the connecting panels This has the effect of making it smaller.
