Description

[Detailed explanation of the idea] This idea concerns the structure of the lower part of the wall.

Conventionally, the type shown in Fig. 1 has been used as the load-bearing wall that forms the exterior wall of a house. That is, reference numeral 1 designates a load-bearing wall panel, in which a joint piece 5 at the lower end of the load-bearing wall panel 1 is joined to a base 4 fixed to anchor bolts 3 of a foundation 2 with bolts and nuts 6. Load-bearing wall panel 1
The upper end of is fixed to the beam 7. 8 is mortar, and a lath (not shown) is provided between the lower end of the load-bearing wall panel 1 and the upper surface of the foundation 2. but,
There is a problem in that due to the load applied to the load-bearing wall panel 1, shearing force acts on the bolts and nuts 6 that connect the load-bearing wall panel 1 and the foundation 2, and the bolts and nuts 6 are likely to break.

Therefore, the new seismic design proposed the load-bearing wall structure shown in Figures 2 and 3. That is,
A leg portion 9 consisting of a bottom plate 9a and two vertical pieces 9b is provided at the lower end of the load-bearing wall panel 1′, and the bottom plate 9 of the leg portion 9
A is fixed to the anchor bolt 3 of the foundation 2 with a nut. With this configuration, tensile bonding is achieved and excellent strength can be obtained. However, the legs 9 of the load-bearing wall panel 1' can be directly connected to the foundation 2 without using the foundation.
There was a problem in that it was not possible to attach a lath for mortar to fix it to the anchor bolt 3. If the lath is attached to the legs 9 of the load-bearing wall panel 1 in advance, there is a problem that it becomes impossible to tighten the anchor bolts 3 and the legs 9, and it also becomes a hindrance to manufacturing and transporting the load-bearing wall panel 1'. .

Therefore, the object of this invention is to provide a structure for the lower part of a wall that allows the legs of the wall panel to be directly fixed to the foundation, while also allowing for easy attachment of laths.

An embodiment of this invention is shown in FIG. In the figure, 10 is a load-bearing wall panel, and leg portions 9 are provided protruding from the lower surface of a lower frame 10a. The leg portion 9 is similar to the example shown in FIGS. 2 and 3, and consists of a bottom plate 9a and two upright plates 9b. The legs 9 are load-bearing wall panels 10
A plurality of them are provided in the width direction. Also, lower frame 1
A lath attachment groove 11 is provided on the lower surface of Oa along the vicinity of the outer edge. The bottom plate 9a of the leg portion 9 is placed on the upper surface of the foundation 2 via a plate-shaped spacer 12, and is fastened and fixed to the anchor bolt 3 planted in the foundation 2 with a nut 13 and a washer 14. The spacer 12 is retracted from the outer edge of the bottom plate 9a of the leg portion 9, and a gap 15 is formed between the bottom plate 9a, the foundation 2, and the spacer 12. 16 is a lath made by bending an iron plate into an L shape, and there are folded parts 16 at the tip of the bottom piece part and the tip of the vertical piece part.
a, 16b are provided. Both ends of the lath 16 are fitted into the gap 15 on the lower surface of the leg portion 9 of the load-bearing wall panel 10 and the mounting groove 11, respectively. The folded portions 16a and 16b of the lath 16 are open as shown by chain lines in FIG. 4 before installation, and are narrowed by being press-fitted into the gap 15 and the installation groove 11. Reference numeral 17 denotes finishing mortar applied to the outer surface of the foundation 2, and its upper part 17a is raised so as to cover the outer surface of the lath 16. In addition,
The lath 16 is provided with a large number of punched holes or raised pieces in order to improve adhesion to the mortar 17. Further, the lath 16 may be a wire lath.

In this way, the lath attachment groove 11 is provided on the lower end surface of the load-bearing wall panel 10, and a gap 15 is provided between the leg portion 9 and the foundation 2 by the spacer 12, and the L
Both ends of the shaped laths 16 are fitted into these lath mounting grooves 11 and gaps 15, so after fixing the load-bearing wall panel 10 to the foundation 2, all you have to do is insert it and tighten screws or nail it. The lath 16 can be easily attached without having to perform Moreover, it can be fixed securely. Therefore, unlike the case where a lath is attached to a load-bearing wall panel in advance, it does not become difficult to fix the load-bearing wall panel 10 to the foundation 2, and it does not become a hindrance to transportation or the like. In addition, the spacer 12 allows the foundation 2
Errors at the top surface level can be absorbed.

As described above, the structure of the lower part of the wall of this invention includes a lath mounting groove provided on the lower end surface of the load-bearing wall panel, a gap provided by spacers between the legs and the foundation, and both ends of the L-shaped lath. is inserted into the lath mounting groove and gap, so the lath can be easily installed even though the legs of the load-bearing wall panel are directly fixed to the foundation. .
