[Background Art]

 The floor joists of the house are connected to the floor beams, and the ridges of the ceiling are connected to the ceiling beams, and these connections are made using brackets.

[0003]

[Problems to be solved by the invention]

 The same applies in that both the joists and the bezels have floor and ceiling facings attached and are members that support them.However, since a large load acts on the floor, the vertical dimensions of the joists are larger than those of the bedding. In order to support this large load with the floor beams, the ends of the joists are inserted and placed in the floor beams, whereas the ends of the field edges are not inserted into the ceiling beams.

[0004] Accordingly, the length of the joist and the hem are different from the length in addition to the vertical dimension. Due to such a difference in size, conventionally, the bracket connecting the joist and the floor beam, and the hem and the ceiling beam have the same size. The brackets connecting the two were different, and as a result, two types of brackets had to be prepared.

An object of the present invention is to provide a bracket which can be used for connecting a joist and a floor beam and for connecting a ridge and a ceiling beam and can be shared.

A receiving member 13 is arranged inside the beam 4 and connected to the beam 4, and two connecting members 14 are laid between the receiving member 13 and the edges 7 at both ends. The receiving member 11 is for attaching a floor material together with the floor beams 5 and 6 and the joist 9, and the receiving member 13 is provided for the ceiling beams together with the beams 3 and 4 and the field edge 7. This is for attaching the surface material for

FIG. 2 shows a floor portion of the housing unit 1, and FIG. 5 shows a ceiling portion. 3 and 4 are cross-sectional views taken along lines III-III and IV-IV of FIG. 2 in a state where a floor material to be a floor is attached, and FIGS. 6 and 7 are VI-VI of FIG. VII-VII sectional view. As shown in these figures, the pillar 2 is made of a metal square pipe, and the beams 3 to 6 are made of a metal channel material. On the other hand, the receiving members 11 to 13 are made of wood together with the field edge 7 and the joist 9.

As shown in FIGS. 2 and 5, the beams 3 and 5 are connected to the column 2 via fittings 15 and 16, and the edge 7 and the joist 9 have the same bracket 17 on the beams 3 and 5. Are joined through The specific shape of the bracket 17 is shown in FIG.

The bracket 17 has upper and lower horizontal flange portions 18 and 19 and a vertical extension portion 20 extending forward from the flange portions 18 and 19, and extends between the flange portions 18 and 19. A rib 21 is provided at the base of the protrusion 20 by extrusion press working in the thickness direction of the extension 20, and the rigidity of the bracket 21 is increased by the reinforcing effect of the rib 21.

The extension 20 has a substantially triangular shape in which a lower side 20A is horizontal and an upper side 20B is inclined forward and downward, and the extension 20 has holes 22 to 26 formed therein. The hole 22 is formed at the frontmost portion, the holes 23 and 24 are formed at the middle portion, the holes 25 and 26 are formed at the rearmost portion, and the holes 23 and 24 and the holes 25 and 26 are formed vertically apart.

The upper and lower flange portions 18 and 19 are spot-welded to the upper and lower inner surfaces of the beams 3 and 5 by a channel material as shown in FIGS. Then, the wood edge 27 as a connecting tool is selectively inserted into three of the holes 22 to 26 of the extension portion 20, so that the bezel 7 and the joist 9 are joined to the extension portion 20.

Specifically, as shown in FIG. 3, the joist 9 of the floor has a large vertical dimension so as to be able to resist a large load acting on the joist 9, and its end is inserted and placed in the beam 9. Therefore, the wood screws 27 are inserted into the holes 22, 25, and 26 of the holes 22 to 26, which have the largest distance in the vertical direction and the front and rear direction, to join the joists 9. On the other hand, as shown in FIG. 6, the top edge 7 of the ceiling to which a large load does not act has a small vertical dimension, and its end is not inserted and placed in the beam 3, so that the vertical direction of the holes 22 to 26 is small. The wood screws 27 are inserted into the holes 22, 23, and 24 having the smallest distance in the front-rear direction to join the field edge 7. As a result, the ridge 7 and the joist 9 are joined to the beams 3 and 5 using the same bracket 17.

As shown in FIGS. 2 and 4, the connection of the connecting member 10 to the beam 6 is also performed using the bracket 17. The connection of the connecting member 10 to the joist 9 is performed using a bracket 28, and the specific shape of the bracket 28 is shown in FIG. The bracket 28 has protruding portions 31 and 32 protruding forward from the left and right flange portions 29 and 30, and these protruding portions 31 and 32 are connected by a connecting portion 33 at the lower end, and the flange portions 29 and 30 and the protruding portions are formed. As shown in FIG. 4, the wood screws 17 are inserted into the holes 34 formed in the holes 31 and 32, so that the joists 9 and the connecting members 10 are connected.

As shown in FIGS. 5 and 7, the connection between the ridge 7 and the connecting member 14 and the connection between the receiving member 13 and the connecting member 14 are also performed by the bracket 28.

As shown in FIGS. 3 and 4, the receiving members 11 and 12 are mounted on the connecting members 10 and the cutouts 10A and 9A of the joists 9, and the ends of the receiving members 11 are connected to the columns 2 as shown in FIG. It is fixed to the bracket 36 connected by the connecting hardware 35, and the end of the receiving member 12 is fixed to the connection hardware 16. Further, as shown in FIG. 5, the receiving member 13 is connected to the beam 4 via a bracket 37, and an end of the receiving member 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 joined with the ridges 7 and joists 9 perpendicular to the beams 3 and 5, so that these beams 3 and 5 are made of channel material. However, the beams 3 and 5 have high rigidity against torsion. Further, since the connecting members 10 and 14 which are perpendicular to the beams 4 and 6 are also connected to the beams 4 and 6, even if the beams 4 and 6 are made of a channel material, the beams 4 and 6 can be used. Has a high rigidity against torsion. Accordingly, the housing unit 1 has a structure that is generally resistant to lateral buckling.

As shown in FIGS. 3 and 4, on the upper surface of the joist 9, a surface material 40 made of a particle board or the like serving as a floor is arranged. The length of the face member 40 in the left-right direction and the front-rear direction is up to the receiving members 11 and 12 and does not reach the beams 6 and 5. The face material 40 is fixed to the joist 9 and the receiving materials 11 and 12 by gluing and nailing. Such face materials 40 are provided for adjacent house units 1, and connecting face materials 41 and 42 are arranged between the adjacent house units 1. These connecting face members 41 and 42 have relatively large widths reaching the receiving members 11 and 12 of the respective housing units 1. These face members 41 and 42 are also fixed to the receiving members 11 and 12 by gluing and nailing. Thereafter, a finishing material is arranged on the upper surfaces of the face material 40 and the connecting face materials 41 and 42, and the floor is finished. Further, a surface material serving as a ceiling is fixed to the underside of the bezel 7 and the lower surface of the receiving material 13 by gluing and nailing, and a finishing material is attached to the surface material to finish the ceiling.

According to the above-described embodiment, when the ridge 7 is connected to the beam 3 serving as a ceiling beam, and when the joist 9 is connected to the beam 5 serving as a floor beam, these connections are made. As described above, the brackets 17 provided with the holes 22 to 26 in the extending portion 20 in the vertical direction and the front-back direction are used, so that the vertical dimension of the bezel 7 and the joist 9 are different. However, by selectively inserting a wood screw 27 as a fastener into the holes 22 to 26, the same bracket 17 is used to connect the beam 3 to the field edge 7 and to connect the beam 5 to the joist 9. The coupling can be performed, and the bracket 17 can be shared.

In addition to the above, according to the present embodiment, nailing of the face material 40 and the connecting face materials 41 and 42 is performed not on the metal beams 5 and 6 but on the wooden receiving materials 11 and 12. Therefore, even if the thickness of the beams 5 and 6 is increased in order to increase the rigidity of the housing unit, the nailing operation can be easily performed.

Further, since the connecting face members 41 and 42 have a large width dimension that reaches the receiving members 11 and 12 of the respective housing units 1, even if the adjacent housing units 1 are vertically stepped. However, the inclination angles of the connecting face materials 41 and 42 become small, and as a result, a good floor finish can be achieved. As shown in FIGS. 3 and 4, if gaps S1 and S2 are provided between the connecting face materials 41 and 42 and the beams 5 and 6, the connecting face materials 41 and 42 can be formed. Even if it is inclined, it is possible to prevent interference with the beams 5 and 6.

Although the receiving members 11 and 12 are members for attaching the surface member 40 and the connecting surface members 41 and 42 similarly to the joists 9, these receiving members 11 and 12 are connected members. 10, the joist 9 is mounted on and supported by the joist 9, so that the sectional area may be smaller than that of the joist 9.

Furthermore, if the dimensions between the receiving members 11 and the receiving members 12 of the adjacent housing units 1 are set on the basis of the module that determines the dimensions of the housing unit 1, the connecting face members 41, 42 can be easily manufactured without waste of materials.

Although the present embodiment described above is directed to a bracket used for floor beams and ceiling beams of a housing unit for building an industrialized house, the present invention is directed to floor beams and ceiling beams of a general house. Also applicable to brackets used for Further, the bracket according to the present invention can be applied to the case where the length of the floor material or the connecting surface material, the mounting structure, and the like are other than those of the above embodiment.
