Further, the second protruding portion 43E does not have the second through hole portion 44.

The first protrusion 33D and the first protrusion 33E are protrusions that protrude from the mutually opposing surfaces of the first protrusion 33D and the first protrusion 33E, and the first recess 12 of the first wall surface 11 and the second It has a guide portion 33p that guides the insertion member 50 inserted between the second recess 22 of the wall surface 21. Similarly, each of the second protrusion 43D and the second protrusion 43E is a protrusion that protrudes from the mutually opposing surfaces of the second protrusion 43D and the second protrusion 43E, and the first recess 12 of the first wall surface 11 and the second recess 22 of the second wall surface 21.

A pair of guide parts 33p are provided near the tips 33t of the first protrusions 33D and 33E, and near the upper and lower ends of the first protrusions 33D and 33E, respectively. It is provided. Further, the guide portion 43p is located near the tips 43t of the second protrusion 43D and the second protrusion 43E, and near the upper and lower ends of the second protrusion 43D and the second protrusion 43E, respectively. A pair of them are provided. However, the arrangement and quantity of the guide parts 33p and 43p are arbitrary.

Further, the guide portions 33p and 43p do not necessarily need to be in constant contact with the insertion member 50, but may be in contact with the insertion member 50 inserted between the first recess 12 and the second recess 22 as appropriate. It is sufficient if it is possible to guide 50. Further, the first protrusion 33D and the first protrusion 33E do not need to have different shapes, and the second protrusion 43D and the second protrusion 43E do not need to have different shapes. For example, the guide parts 33p and 43p are first protrusions having the same shape, like the first protrusion 33B, the first protrusion 33C, the second protrusion 43B, and the second protrusion 43C in the fourth embodiment. 33B or the like. Further, the guide portions 33p, 43p may have any shape as long as they can guide the position when inserting the insertion member 50, and may be rod-shaped or plate-shaped, and may not be protrusions. Further, the guide portion 33p may be provided only on one of the first protrusion 33D and the first protrusion 33E, and the guide portion 43p may be provided on either one of the second protrusion 43D and the second protrusion 43E. It may be provided only in the That is, the guide parts 33p, 43p may be partially provided in the first protrusions 33D, 33E and the second protrusions 43D, 43E. Except for what has been described above, this embodiment is the same as the first embodiment described above.

In this embodiment, the first recess 12 and the second recess 22 are connected to each other by the guide portions 33p and 43p provided in the first protrusion 33D, the first protrusion 33E, the second protrusion 43D, and the second protrusion 43E, respectively. Since the insertion member 50 inserted between the first recess 12 and the second recess 22 is guided, it is easy to determine the position of the insertion member 50 when the insertion member 50 is inserted between the first recess 12 and the second recess 22. be.

A sixth embodiment of the present invention will be described below. As shown in FIGS. 7(A) and 7(B), the wall member joining structure 1F of the sixth embodiment does not include the insertion member 50. The tip 33t of the first protrusion 33F of the first protrusion member 30D is located outside the first recess 12, and the tip 43t of the second protrusion 43F of the second protrusion 40D is located outside the second recess 22. There is. Therefore, in a side view looking between the first wall surface 11 of the first wall member 10E and the second wall surface 21 of the second wall member 20E as shown in FIG. 7(B), the first The protrusion 33F and the second protrusion 43F of the second protrusion member 40D have portions that overlap with each other.

As shown in FIGS. 7(A) and 7(B), similarly to the first protruding part 33A and the second protruding part 43A of the first embodiment, the first protruding part 33F extends through the first through hole part 34. The second protrusion 43F has a second through hole 44. In a side view looking between the first wall surface 11 and the second wall surface 21, the first through hole portion 34 of the first protrusion 33F and the second through hole portion 44 of the second protrusion 43F overlap with each other. has. Except for what has been described above, this embodiment is the same as the first embodiment described above. The first protrusion 33F and the second protrusion 43F may be in contact with each other or may be spaced apart from each other.

In this embodiment, when viewed from the side between the first wall surface 11 and the second wall surface 21, the first protrusion 33F and the second protrusion 43F have portions that overlap with each other. Therefore, the force is more reliably transmitted between the first protruding member 30D and the second protruding member 40D via the filler 60, and the force that separates the first wall member 10E and the second wall member 20E from each other and the first It is possible to further improve the resistance against the force that shears the wall member 10E and the second wall member 20E in the direction along the first wall surface 11 and the second wall surface 21.

In addition, in this embodiment, in a side view looking between the first wall surface 11 and the second wall surface 21, the first through hole section 34 of the first protrusion 33F and the second through hole section of the second protrusion section 43F. 44 has a mutually overlapping portion. Therefore, by entering the filler 60 into the first through-hole section 34 and the second through-hole section 44 that overlap with each other, a force that separates the first wall member 10E and the second wall member 20E from each other and a force that separates the first wall member 10E and the second wall member 10E from each other. The resistance against the force that shears the second wall member 20E in the direction along the first wall surface 11 and the second wall surface 21 can be further improved.

Moreover, in this embodiment, since the first protruding part 33F of the first protruding member 30D and the second protruding part 43F of the second protruding member 40D have a portion where they overlap with each other, the first protruding part 33F of the first protruding part 33F is By increasing the protrusion length of the second protrusion 43F and the protrusion length of the second protrusion 43F from the second wall surface 21, the first through-hole portion 34 and the second through-hole portion 44 can be made larger. Therefore, the force is transmitted more reliably via the filler 60 filled in the large first through-hole portion 34 and the second through-hole portion 44, and the force that separates the first wall member 10E and the second wall member 20E from each other. And the resistance against the force that shears the first wall member 10E and the second wall member 20E in the direction along the first wall surface 11 and the second wall surface 21 can be further improved.

A seventh embodiment of the present invention will be described below. As shown in FIGS. 8(A) and 8(B), the wall member joining structure 1G of the seventh embodiment has the first wall member 10E and the second wall member of the wall member joining structure 1F of the sixth embodiment. 20E, a reinforcing bar 73 is provided which is inserted through the first through hole 34 of the first protrusion 33F and the second through hole 44 of the second protrusion 43F. When forming the wall member joining structure 1G as described above, after the first wall member 10E and the second wall member 20E are arranged as in the first embodiment, the first wall surface 11 and the second wall member 20E are arranged from the side. A reinforcing bar 73 is inserted into the first through hole portion 34 and the second through hole portion 44 through the second wall surface 21 . Except for what has been described above, this embodiment is the same as the first embodiment described above.

In this embodiment, the wall member joining structure 1G includes the reinforcing bars 73 inserted into the first through hole 34 of the first protrusion 33F and the second through hole 44 of the second protrusion 43F. Further improves the resistance against the force that separates the member 10E and the second wall member 20E from each other and the force that shears the first wall member 10E and the second wall member 20E in the direction along the first wall surface 11 and the second wall surface 21. be able to.
