Description

[Detailed description of the invention] [Technical field] This invention relates to a support structure for a partition wall panel used on the second floor of a prefabricated house.

[Background technology]

Conventionally, partition wall panels, which serve as load-bearing walls, have been used on the second floor of prefabricated houses using the panel construction method.
However, it is prone to buckling deformation at the base of the legs and has low yield strength.
As a result, the number of sheets used increased, leading to problems such as not being able to create a large one-room space or having less flexibility in floor plan. In addition, conventional load-bearing partition wall panels need to be jointed to columns, which necessitates providing a large number of working holes in the columns, resulting in poor workability.

[Purpose of invention]

The purpose of this invention is to provide a support structure for a partition wall panel that can improve the strength of the partition wall panel, improve flexibility in layout, and facilitate joining work.

A joint plate is provided on the lower end of the joint mounting member that extends to both sides in the thickness direction of the panel body, each having a bolt insertion hole in this overhang, and a pair of support bases that are erected at a distance from each other. A U-shaped joint base consisting of a fixed part that continues between the lower parts of the support base parts is arranged on both sides of the beam in the width direction, and the overhanging part of the joint plate is placed on the upper surface of each support base part. and a fixing part is fixedly provided on the upper surface of the beam, a screw hole is drilled at a position opposite to the bolt insertion hole of the pair of support parts, and the screw hole is inserted into the bolt insertion hole of the joint plate to connect the pair of support parts. The panel body is fixed to the joint stand by tightening bolts into the screw holes.

According to the configuration of this invention, there are the following effects.
That is, since the joint attachment member reinforces the legs against buckling deformation, the strength of the panel body is improved. Therefore, the number of panels used is small, and the flexibility of floor plan is improved. Furthermore, since the panel body is joined to the joint stand via the joint attachment member, there is no need to provide a working hole in the column, and the joining work can be easily performed.

An embodiment of this invention is shown in FIGS. 1 to 7. 2 and 3 show a partition wall panel 1, in which joint plates 4 are joined via joint attachment members 3 to the lower end outer surfaces of vertical frame members 2 on both sides of a panel body 1'. The panel body 1' has a load-bearing wall structure, with vertical frame members 2 and horizontal frame members 5 made of channel steel (Fig. 4).
A structural facing material 7 made of particle board and an interior base material 8 made of gypsum board are attached to both sides of the panel frame made up of the and middle crosspieces 6 and fixed with screws.
The dimension of screw 9 from the edge of the panel is approximately 20 mm. The joint mounting member 3 is made of outward facing channel steel and is welded to the vertical frame member 2. The joint plate 4 is made of a steel plate, and is welded to the lower end surface of the joint mounting member 3 so as to protrude to both sides. Bolt insertion holes 10 are formed in the protruding parts on both sides of the joint plate 4.

Next, the support structure of this partition wall panel 1 will be explained. In FIG. 6, reference numeral 11 indicates an exterior wall panel on the first floor, and reference numeral 12 indicates an exterior wall panel on the second floor, which is provided via a sill 13 above the exterior wall panel 11 on the first floor. Note that 24 and 25 are groove-shaped outer wall joint hardware that connects the outer wall panel 12 and an adjacent outer wall panel (not shown). Further, 14 is a through post. A floor beam 15 is provided protrudingly between the through column 14 and the trunk sill 13. The floor beam 15 is made of I-beam steel in cross section, has end plates at both ends, and is bolted to the column 14 and the joist 13. On the upper surface of the upper flange 15a of the floor beam 15, a partition wall panel 1 is placed above the floor beam 15.
Fixing bolt 3 below each joint mounting member 3 of
0 and 32 are welded and erected. (See Figure 5). Reference numeral 16 designates a U-shaped joint stand made of iron block, which is fixed on the upper flange 15a by inserting the fixing bolts 30, 32 into the bolt insertion holes 34, 34 of the fixing part 41, and tightening them with nuts 38 through washers 36. be done. A pair of support portions 40 and 42 are integrally formed on both sides of the floor beam 15 of the joint stand 16 in the width direction. Furthermore, screw holes 18 are bored in the upper surfaces of the pair of support base parts 40 and 42 at positions facing the bolt insertion holes 10 of the joint plate 4, respectively. Then, the bolts 19 are inserted into the bolt insertion holes 10 of the joint plate 4 through the washers 44 and fastened to the screw holes 18 of the pair of support parts 40 and 42 to fix the joint mounting member 3 to the joint base 16. Then, the partition wall panel 1 is fixed to the joint stand 16 (see FIG. 1). Also,
In FIG. 6, on the upper end surface of each partition wall panel 1, a square pipe-shaped joint metal fitting 26 made of steel is bolted to the upper frame 1a of the partition wall panel 1. Furthermore, the joint hardware 26 is connected to the ridge truss 2.
7 is bolted to the upwardly grooved lower chord member 28,
The upper end of the partition wall panel 1 is fixed to a ridge truss 27.

According to the partition wall panel support structure configured in this way, the partition wall panel 1 is reinforced against buckling deformation at the base of the legs by the groove-shaped joint mounting members 3, so that the partition wall panel 1 is resistant to vertical loads and horizontal forces. Improves durability. Therefore, it becomes possible to reduce the number of partition wall panels 1 and create a large one-room room. Furthermore, by combining with other small-sized non-load-bearing partition wall panels, the number of partition wall panels 1 that serve as load-bearing walls can be reduced and the flexibility of the floor plan can be increased. Furthermore, since the load-bearing partition wall panel 1 can be installed on the second floor, the degree of freedom in opening the outer wall of the second floor is improved.

Furthermore, since the partition wall panel 1 is not connected to the pillars but is connected to the joint stand 16 via the joint attachment member 3,
There is no need to provide working holes in the columns, and the joining work of the partition wall panels 1 can be easily performed.

In addition, the joint stand 16 is fixed to the upper surface of the floor beam 15,
Since the partition wall panel 1 is fixed to this joint stand 16, a space is created between the partition wall panel 1 and the floor beam 15. Therefore, this space can be used for wiring and piping.

Furthermore, since the pair of support base parts 40 and 42 that support both ends of the joint plate 4 are connected by the fixing part 41 and are integrally formed as one joint base 16, the number of parts can be reduced, and the floor When fixing to the beam 15, it is only necessary to fix at one location, so the fixing work can be easily performed.

The width of this partition wall panel 1 is, for example, the module's 900 mm minus the joint spacing of 110 mm.
The size is 790 mm, which allows for continuous construction and systemization with other small non-load-bearing partition wall panels.

In addition, as shown in FIG. 7, four support portions 40, 4 are provided so that two adjacent joint mounting members 3 of adjacent partition wall panels 1 can be attached.
A joint stand 17 with 2, 40', 42' may also be used. Note that a bolt insertion hole (not shown) is provided at the center of the fixing portion 41' of the joint stand 17.

The support structure for the partition wall panel constructed in this manner also provides the same effects as in the first embodiment.

[Effect of idea]

The partition wall panel support structure of this invention provides the following effects.

Since the groove-shaped joint attachment members joined to the lower ends of both sides of the panel body respectively reinforce the legs against buckling deformation, the strength of the panel body is improved. Therefore, the number of panels used is small, and the flexibility of floor plan is improved.

Furthermore, since the panel body is structured to be joined to the joint stand via the joint attachment member, there is no need to provide a working hole in the column, and the joining work can be easily performed. As mentioned above, the joint stand creates a space between the partition wall panel and the floor beam to allow wiring and piping, and also has the effect of adjusting the height of the partition wall panel. . In other words, when using partition wall panels of the same shape on the first and second floors, the height of the joint base must be changed because the dimensions between the foundation and the bottom of the beam on the first floor are different from the dimensions between the top and bottom of the beam on the second floor. Adjust by. In this case, a plurality of joint stands with different heights may be prepared and an appropriate one may be selected and used. In addition, the dimensions between the foundation and the bottom of the beam differ depending on the type of building, so they can be adjusted in the same way.
