Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a load-bearing wall panel that can support horizontal forces acting in directions parallel to the front and back surfaces of a wall panel body.

[Prior Art] Conventionally, the load-bearing wall panel A has a connecting plate 2 provided at the lower part of the wall panel main body 1, as shown in FIGS. 4 and 5, and a through hole bored in the connecting plate 2. 5, insert the anchor bolt 4 protruding from the foundation 3, and connect the connecting plate 2 and the anchor bolt 4.
By connecting these, the wall panel main body 1 is fixed. The through hole 5 drilled in the connecting plate 2 is a hollow hole 5' whose inner diameter is considerably larger than the outer diameter of the anchor bolt 4 so as to absorb displacement of the anchor bolt 4. This relatively large through hole 5 allows the connecting plate 2 and the anchor bolt 4 to be connected while absorbing displacement of the anchor bolt 4.

[Problems to be Solved by the Invention] By the way, the load-bearing wall panel A as described above is designed to be able to support a horizontal force in a direction parallel to the front and back surfaces 1a of the wall panel main body 1, that is, to support a building. It is erected on the foundation 3 so that the wall panel main body 1 can support the horizontal force applied in the horizontal direction. However, if the through hole 5 provided in the connecting plate 2 is simply formed into a larger hole 5' with priority given to connectivity with the anchor bolt 4 as in the conventional example described above, the direction of the horizontal force, that is, The anchor bolt 4 is connected in a state in which it moves within the through hole 5 in a direction parallel to the front and back surfaces 1a of the wall panel main body 1, and in this manner, the anchor bolt 4 can move within the through hole 5. , there was a problem that it could not be erected on the foundation 3 to ensure horizontal force support.

The present invention attempts to solve the above-mentioned problems, and its purpose is to provide a structure on the foundation so that it can be well connected to the anchor bolt and can reliably support the horizontal force. The purpose is to provide load-bearing wall panels that can be erected.

[Means for Solving the Problems] In order to achieve the above object, the load-bearing wall panel A of the present invention has a connecting plate 2 provided at the lower part of the wall panel body 1 with anchor bolts 4 protruding from the foundation 3. A load-bearing wall panel that is connected to and erected on the foundation 3 and supports horizontal force applied in a direction parallel to the front and back surfaces 1a of the wall panel main body 1,
A through hole 5 through which an anchor bolt 4 is inserted is provided in the connecting plate 2, and the through hole 5 is formed into a long hole shape in a direction orthogonal to the front and back surfaces 1a of the wall panel main body 1.

[Function] The load-bearing wall panel A is assembled by inserting anchor bolts 4 into the through holes 5 of the connecting plate 2 provided at the lower part of the wall panel body 1.
It is erected on the foundation 3 by connecting the and anchor bolts 4. Since the through hole 5 provided in the connecting plate 2 has a long hole shape in a direction perpendicular to the front and back surfaces 1a of the wall panel main body 1, it becomes parallel to the front and back surfaces 1a of the wall panel main body 1 after connection. It is difficult to cause misalignment in the direction, that is, the direction in which horizontal force is applied, and after installation, horizontal force can be reliably supported without causing misalignment.

[Example] Hereinafter, the present invention will be explained in detail based on illustrated embodiments.

As shown in FIG. 1, the load-bearing wall panel A is mainly composed of a wall panel body 1. Connecting members 6 connected to beams or the like are provided at both ends of the upper surface of the wall panel main body 1, and the upper part of the wall panel main body 1 is fixed by the connecting members 6.

Leg pieces 7 are provided at both lower ends of the wall panel body 1 to project downward, and a connecting plate 2 is provided at the lower end of the leg piece 7.

The wall panel main body 1 can be erected on the foundation 3 by connecting the connection plate 2 to an anchor bolt 4 protruding from the foundation 3. Connecting plate 2
has both ends protruding laterally from the end of the leg piece 7, and this protruding portion has a through hole 5 into which the anchor bolt 4 is inserted.
are provided for each. Then, by inserting the anchor bolt 4 into the through hole 5, a fixing member 8 such as a nut 8a is screwed onto the anchor bolt 4 to connect the connecting plate 2 and the anchor bolt 4, and the wall panel main body 1 is installed as a foundation. It is designed to be installed on top of 3. This through hole 5 has a long hole shape in a direction perpendicular to the front and back surfaces 1a of the wall panel main body 1, and when the anchor bolt 4 is inserted, the front and back surfaces 1a of the wall panel main body 1
The position can be adjusted in the direction orthogonal to the

As shown in FIG. 2, the anchor bolt 4 and the connecting plate 2 are connected by fixing members 8 such as a gap closing member 8b, a washer 8C, and a nut 8a.
Connecting plate 2 so that anchor bolt 4 is located in through hole 5
is placed on the foundation 3, a gap closing member 8b is attached to the anchor bolt 4, this gap closing member 8b is placed in the through hole 5, a washer 8c is passed through the anchor bolt 4, and a nut 8a is screwed. It connects the connecting plate 2 and the anchor bolt 4. At this time, the gap closing member 8b is formed to be shorter than the length of the elongated through hole 5, and the connecting plate 2 is movable in the length direction of the through hole 5 within the through hole 5. The position can be adjusted by moving it. In addition, the gap closing member 8b
When placed in the through hole 5, the end surface of the connecting plate 2 is in contact with the side surface in the transverse direction of the through hole 5, and when connected, the connecting plate 2 is parallel to the front and back surfaces 1a of the wall panel body 1. It is designed not to move in any direction. In other words, the load-bearing wall panel A can reliably support horizontal forces applied in directions parallel to the front and back surfaces 1a of the wall panel main body 1.

FIG. 3 shows another embodiment of the gap closing member 8b, in which a saw blade-shaped uneven portion 9 is provided on the side surface of the gap closing member 8b, and the anchor bolt 4 is inserted into the gap closing member 8b. When disposing the gap closing member 8b in the through hole 5 in the condition that It can be placed like this. At this time, the through hole 11 of the gap closing member 8b through which the anchor bolt 4 is inserted is formed in a circular shape, and the contact portion with the outer surface of the anchor bolt 4, which has a circular cross section, makes surface contact. Thus, by making surface contact and having a large contact area, movement of the anchor bolt 4 within the through hole 11 can be suppressed as much as possible. Here, if the anchor bolt 4 is in contact with the linear end surface of the through hole 5 as shown in FIG. 5, that is, the outer surface of the anchor bolt 4 and the inner surface of the through hole 5 are In the case of point contact, since the contact area is small due to point contact, the position of the anchor bolt 4 can easily change due to external force, and misalignment is likely to occur.

[Effects of the Invention] As described above, the load-bearing wall panel of the present invention is provided with a through hole through which an anchor bolt is inserted in the connecting plate, and this through hole is formed into a long hole in a direction perpendicular to the front and back surfaces of the wall panel body. Therefore, the anchor bolt can move freely in the direction perpendicular to the front and back surfaces of the wall panel body within the through hole, but is restrained from moving in the direction parallel to the front and back surfaces of the wall panel body. The position can be adjusted in the long hole in the direction perpendicular to the main body, and the horizontal force applied in the direction parallel to the front and back surfaces of the wall panel body can be supported by preventing the anchor bolt from moving inside the hole. It can reliably support horizontal forces.
