TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method for structurally reinforcing a non-bearing wall in an existing building part to be a bearing wall when adding or renovating a house or the like.
[0002]
[Prior art]
In the extension and remodeling work of houses, etc., due to changes in the structure of the house, non-bearing walls used in the existing building part may receive a load on the upper part, in this case, the non-bearing walls It must be a load bearing wall. FIG. 10 is a diagram illustrating an example of the non-bearing wall, showing a state in which the outer wall panel 82 is removed from the frame 81 of the non-bearing wall 80 and the frame 81 is exposed to the outside. As shown in the figure, the frame-shaped shaft set 81 includes a pair of left and right shaft columns 83 parallel to each other, a pair of upper and lower shaft bars 84 orthogonal to the shaft columns 83, and a central portion in the longitudinal direction of the shaft columns 83. And a middle bar 85 provided in parallel with the shaft bar 84. As a means for converting the non-bearing wall 80 into a bearing wall, there is a method in which the non-bearing wall 80 is removed from its outer wall together with its frame 81 and replaced with a non-illustrated existing bearing wall frame.
[0003]
Another method for making the non-bearing wall a bearing wall is to remove the frame of the non-bearing wall and to add a bearing brace connecting the corners formed by the frame to each other without removing the frame. There is also. In this case, both ends of the load-bearing brace are joined to the corner by welding, or a brace mounting bracket is attached to the corner by bolting, and both ends of the load-bearing brace are fixed to the brace mounting bracket by bolting. (See Patent Document 1).

[Problems to be solved by the invention]
However, in the method of removing the non-bearing wall 80 together with the frame 81 from the outer wall portion and replacing it with the existing frame of the bearing wall, the frame 81 of the non-bearing wall 80 is removed or the shaft of the bearing wall is incorporated. There is a problem that a great deal of time and labor is required for the work. In addition, when the work of removing the frame 81 of the non-bearing wall 80 is performed, the interior of the interior wall panel (not shown) may be broken due to breakage of the frame of the interior wall panel (not shown) or wrinkling of the cloth attached to the interior wall panel. There is a problem that there is a case that must be performed.
[0006]
In addition, there is also a problem that the non-bearing wall 80 removed together with the frame 81 is generated as a large amount of industrial waste, and it takes a lot of cost to transport and treat the waste.
[0007]
In addition, in the method in which a load-bearing brace is added to the non-bearing wall frame to form a load-bearing wall, for example, when a middle crosspiece is provided inside the frame, the middle crosspiece is prevented from interfering with the middle crosspiece. In order to add a load-bearing brace without cutting off, it is necessary to dispose the load-bearing brace in two upper and lower stages. Furthermore, the method of adding both ends of the load-bearing brace to the corners of the frame by welding has a problem that work cannot be performed unless the person is qualified to perform welding. The reliability is low and there is a problem in the reliability of construction.
[0008]
In addition, in the method of using the brace mounting bracket to add the load-bearing brace to the frame, the work of mounting the brace mounting bracket to the corner portion by bolting requires the shape of the brace mounting bracket, You can only work from inside. For this reason, since it is necessary to remove the inner wall panel and perform the work, there is a problem that the interior must be redone, for example, as in the case described above, such that the cloth attached to the inner wall panel is wrinkled. .
[0009]

A pair of the load-bearing braces intersect each other at the notch portion of the reinforcing middle bar, and each end portion is fixed to a corner formed by the shaft post and the shaft bar at a relative angular position by a fixing tool. Fixing brace mounting process,
A reinforcing member mounting step of mounting a middle crossbar reinforcing member for closing and reinforcing the notch portion of the middle crossbar while avoiding an intersection of the load-bearing braces. Law. Inside the shaft pillar and the shaft bar arranged in a frame shape, a reinforcing middle bar having a cutout at the center in the longitudinal direction is attached to the shaft by attaching both ends to the center in the longitudinal direction of the shaft pillar. The pair of load-bearing braces are disposed substantially parallel to the crosspiece, and a pair of bearing braces intersect each other at the notch portion of the reinforcing middle crosspiece. A middle crosspiece reinforcing member fixed to a corner portion at a position by a fixing tool, for closing and reinforcing the notch portion of the middle reinforcing crosspiece, is disposed while avoiding an intersection of the load-bearing braces. Load-bearing wall structure. Reinforcement in which a reinforcing shaft for reinforcing the shaft is arranged along the shaft, inside the shaft and the shaft bar arranged in a frame shape, and a notch is formed in the center in the longitudinal direction. The middle crosspiece is disposed substantially in parallel with the shaft crosspiece by attaching both ends to the longitudinal center portion of the reinforcing shaft post, and a pair of load-bearing braces intersect each other at the notch portion of the reinforcing middle crosspiece. As described above, both ends are fixed to a corner formed by the shaft post and the shaft bar at a relative angular position by a fixing tool, and are used to cover and reinforce the notch portion of the reinforcing middle bar. A structure of a load-bearing wall, wherein a middle crosspiece reinforcing member is disposed avoiding an intersection of the load-bearing braces.
