Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a load-bearing wall mounting structure in which a load-bearing wall is installed between a foundation and a beam without creating a step difference with an adjacent non-resisting cover panel. be.

[Conventional technology and its problems]

Some prefabricated houses have a rigid frame structure in which the load is supported by bridge bodies such as columns and beams, and external wall panels are used as non-load-bearing walls. However, the predetermined strength of the pillars and
It rests on a beam, but sometimes a part of it is supported on an exterior wall panel.

In this case, the methods for attaching the non-load-bearing panel and the load-bearing wall (panel) are different. Non-coverage walls do not bear the load of the building, so they can be supported by being fitted between the foundation and beams, but load-bearing walls need to be rigidly fixed between the foundation and beams.

Conventionally, in this type of load-bearing wall, a mounting plate of the load-bearing wall is fixed to an anchor bolt on the foundation with a nut, and the upper mounting plate of the load-bearing wall is bolted to a beam.

At this time, if a gap occurs between the beam and the load-bearing wall, a spacer is inserted between the beam and the load-bearing wall. For this reason, the spacer insertion work is performed at a high place, resulting in poor workability and the insertion of the spacer is often omitted. This creates a gap between the load-bearing wall and the beam, and the load-bearing wall appears to be suspended. Furthermore, it is difficult to accurately position the bottom end of the load-bearing wall, so
If there is a step between the lower end of the adjacent non-load-bearing panel or the lower end of the column bar and the exterior surface of the load-bearing wall, and if there is a horizontal joint between the load-bearing wall and the non-load-bearing wall, if there is a step between both walls, this horizontal joint will be aligned in a straight line. This often results in poor appearance and poor appearance.

The present invention was developed in view of this, and its purpose is to suppress the occurrence of level differences in order to improve workability.

[Means for solving problems]

In a load-bearing wall that is built between a foundation and a beam, and has mounting plates protruding from the upper and lower parts of the wall that are fixed with bolts, due to the dimensional difference between the top and bottom mounting plates of the foundation. Adjust the gap by inserting a spacer as necessary, and fix it together with the mounting plate by tightening bolts. This allows the dimensional difference due to irregularities on the top of the foundation to be adjusted to the lower position of the load-bearing wall, and the spacer This will improve the accuracy of the load-bearing wall mounting position in the width direction of the foundation.

〔Example〕

The mounting structure of the load-bearing wall of the present invention will be explained below based on the illustrated embodiments.

In the figure, 1 is a foundation, 2 is a column established on this foundation 1, 3 is a beam, and 4 is a base [1 is placed on the base, and is fixed between this base ml and the beam 3, and is located in front of the building] It is a load-bearing wall designed to support part of the

The construction of the foundation 1, columns 2, and beams 3 is the same as the conventional method, so a description thereof will be omitted.

A leg mounting plate 5.5 is protruded from the lower frame of the load-bearing wall 4, and an upper mounting plate 6.6 is protruded from the upper frame.
Fix to the foundation 1 and 3 beams via the upper and lower mounting plates 5 and 6. Therefore, the mounting plate 6 has bolt holes 62 in its horizontal plate 61.
washer W from the hole 32 drilled in the lower piece 31 of the beam 3.
The mounting plate 6 is fixed to the beam 3 by inserting the pole B through the pole and screwing a nut onto the tip of the pole B.

Note that the nut may be omitted and a female thread may be provided in the bolt hole 62 drilled in the horizontal plate 61 of the mounting plate 6.

The mounting plate 5 has bolt holes 52 having a diameter larger than that of the anchor bolt 7 at both ends of a horizontal plate 51 provided horizontally at the lowermost end thereof. Then, based on this mounting plate 5, screw N into the anchor bolt 7 buried in the mounting plate 1.
At this time, even if the top surface of the foundation l from which the anchor bolt 7 protrudes is finished with mortar or the like to make it a flat surface, the accuracy of the horizontality of the top surface of the foundation is low, and therefore it is not visually horizontal. However, the top surface of the mortar is actually an uneven surface. For this reason, a spacer 8 is installed as necessary between the mounting plate 5 and the top surface of the foundation l so that the load-bearing wall 4 can be erected horizontally and accurately by adjusting at least the uneven surface of the mounting plate mounting position on the top surface of the mortar. insert. This spacer 8 is used to insert two anchor bolts fi81.81 in accordance with the interval between two anchor bolts 7.7 buried so that they can be inserted from the sides of the anchor bolts 7, for example from the outside of the foundation 1.
A reference surface 82 is provided on a part of the spacer, and the spacer 8 is arranged so that this reference surface 82 is aligned with the marking position provided on the top surface of the base at.

When the spacer is arranged with this marking position aligned with the reference plane, the end face 83 of this spacer 8 is set to match the inner end side face 53 of the horizontal plate 61 of the mounting plate 5, and thereby the load-bearing wall 4 To enable easy positioning. One or more spacers 8 are prepared for one load-bearing wall, and they may all have the same thickness or may have different thicknesses.

Therefore, in order to erect the load-bearing wall 4 constructed as described above on the foundation 1 and the three beams, first install the horizontal plate 6 of the upper mounting plate 6 of the load-bearing wall 4.
Attach it to the bottom surface of the beam 3, pass the pole B through it, and tighten the bolt with the washer W in between if necessary. As a result, the load-bearing wall 4 hangs down from the beam 3. At this time, the bolt hole 52 of the horizontal plate 51 of the lower mounting plate 5
If there is no gap between the top surface of the foundation l and the horizontal plate 51, screw the nut N onto the anchor bolt 7 and position the lower part of the load-bearing wall. It is something that is fixed while doing so. Further, if a gap is created between the top surface of the foundation l and the horizontal plate 51 when the load-bearing wall 4 is suspended @3, a spacer 8 is inserted into the gap between the horizontal plate 51 and the base fal. At this time, the thickness of the spacer 8 is matched to the gap, or two spacers are used to eliminate the gap. And the reference surface 82 of the spacer 8
is aligned with the marking position, and the end surface 83 of the spacer 8 and the inner end side surface 53 of the horizontal plate 51 are aligned, and the bolt (N) is screwed onto the anchor bolt 7 via the washer W and fixed.

〔Effect of the invention〕

In this invention, when a load-bearing wall is constructed between a foundation and a beam, a spacer is inserted between the load-bearing wall's mounting plate and the top of the foundation depending on the finished surface of the top of the foundation. This method has the advantage that the work is done at a relatively low location, the spacer can be easily inserted, work efficiency is improved, and the occurrence of steps in the outer wall panel can be suppressed.
