  The present invention relates to a base structure used for a ceiling, wall, floor, and the like of a building.

  For example, Patent Document 1 describes a wall base structure in which a main material (stud) and a steady rest material are joined in a lattice shape. FIG. 9 is a front view showing the case where the steady rest material is joined to the main material for each stage in the invention, wherein (a) is an inserted state, (b) is an expanded state, and (c). These are the front views which showed the joining state.

  As shown in FIG. 9A, the steadying material 102 according to the base structure 100 is a channel material having a substantially U-shaped cross section with an open lower part, and is an elastically deformable flange portion 106 and the flange. A lip 107 extending inward from the tip of the portion 106 and a claw 108 raised from the tip of the lip 107 are provided (hereinafter, the lip 107 and the claw 108 are collectively referred to as a tip portion 109).

  On the other hand, the main member 101 protrudes inward from both sides of the opening 103, an opening 103 through which the steadying member 102 is inserted, an engaging protrusion 104 protruding upward from the bottom of the opening 103, and the opening 103. And a convex portion 105. The engagement protrusion 104 has a curved portion 104 a and a base shaft portion 104 b that is erected from the lower end of the opening 104. The distance between the end portions 104c and 104c of the curved portion 104a is slightly longer than the distance between the claws 108 and 108. On the other hand, the width of the base shaft portion 104b is formed substantially equal to the distance between the claws 108 and 108.

As shown in FIGS. 9A to 9C, the main material 101 and the steady rest material 102 are joined by pressing the steady rest material 102 from the upper part of the opening 103 toward the lower part and fitting them together. is there.

Then, when further pushed in, as shown in FIG. 9C, the flange portion 106 is restored to its original shape by elastic deformation, so that the distal end portion 109 is brought into contact with the base shaft portion 104b of the engaging protrusion 104 and The base end portion 110 is brought into contact with the convex portion 105. Accordingly, since the main material 101 and the steadying material 102 are restricted from moving in the vertical direction and laterally, the main material 101 and the steadying material 102 can be simply joined to construct the base structure 100. it can.

JP 2002-138605 A (FIGS. 1 to 4)

However, in the present invention, as shown in FIGS. 9B and 9C, a gap 111 must be formed at the lower part of the opening 103 in order to allow the widened tip 109 to escape to both sides. There wasn't. Thereby, since the opening part 103 which concerns on the main material 101 must be formed large, there existed a problem that the intensity | strength of the main material 101 fell. Further, there is a problem in that the strength of the main material 101 is lowered and the strength of bonding between the main material 101 and the steady rest material 102 is lowered.
The present invention has been devised to solve such problems, and provides a base structure that can easily join a main material and a steady-restoring material and has a high joining strength between the main material and the steady-restoring material. This is the issue.

  The present invention devised to solve such a problem is a base structure in which a steady rest material is penetrated through an opening provided in a main material, and the main material is formed from both sides of the opening. The steady rest member has a pair of projecting portions projecting inwardly, and the steadying material is formed on the base plate portion, a pair of flange portions formed at both ends of the base plate portion so as to be elastically deformable, and the flange portion. A pair of recesses recessed inward, and the protrusions of the main member and the recesses of the steadying member are engaged with each other.

  According to this invention, since the pair of protrusions of the opening and the pair of recesses of the elastically deformable flange are engaged, it is possible to easily join the main material by fitting the steady rest. it can. In addition, when the steady rest material is joined to the main material, the flange portion is pressed and contracted from the outside to the inside by the protruding portion. Therefore, it is necessary to form a gap for releasing the tip of the flange portion in a part of the main material. Absent. Therefore, a main material having higher strength than the conventional main material can be formed. Moreover, since the concave part recessed inward is formed in the flange part of a steadying material, the rigidity of a flange part becomes large and the intensity | strength of a steadying material can also be raised. Thereby, a base structure with high bonding strength can be formed.

  The flange portion according to the present invention is characterized in that the flange portion is in close contact with the opening portion from the proximal end portion to the distal end portion of the flange portion.

According to this invention, since the flange portion and the opening portion are in close contact from the base end portion to the tip end portion of the flange portion, the contact area can be increased and concentrated load can be avoided. Can be increased.
That is, as shown in FIG. 9C, the flange portion 106 is in contact with the main member 101 at the distal end portion 109 and the base end portion 110, but the middle portion of the flange portion 106 is in contact with the main member 101. Not done. As a result, the flange portion 106 is in contact with the opening 103 at two points separated from each other by the distal end portion 109 and the proximal end portion 110. There was a possibility that the strength of the steel was lowered. However, according to this invention, since the flange portion and the opening portion are brought into close contact with each other, the load acts and the joint strength can be further increased.

  Moreover, the said flange part which concerns on this invention is urged | biased toward the said side part of the said opening part, It is characterized by the above-mentioned.

  According to this invention, since the urging force works from the inside to the outside of the flange portion, it is possible to prevent the steadying material from rattling and to further increase the bonding strength.

  A bottom portion formed at a lower end of the opening portion, and a pair of lip portions extending inward at the tip portion of the flange portion, and the lip portion abuts on the bottom portion It is characterized by being.

  According to this invention, since the bottom portion and the lip portion are brought into contact with each other, when joining the main material and the steadying material, it is possible to suppress the metallic noise generated by the contact between the two.

  According to the foundation structure according to the present invention, since the foundation structure having a high bonding strength between the main material and the steady rest material can be easily constructed, the strength and workability of the building can be improved.

  As shown in FIGS. 3 and 4, in the present embodiment, the length P of the lower side portion 4 c and the width Q between the front end portions 5 e and 5 e of the steady rest 5 are formed to be substantially equal. However, it is not limited to this. For example, the width between the first contact portions 4e and 4e and the width between the base end portions 5c and 5c are formed to be substantially equal, and the length P of the lower side portion 4c and the tip portion 5e of the steady rest 5 , 5e may be formed such that P <Q. In this way, by forming the steady rest material 5 so as to expand toward the front end portions 5e and 5e, when the stud 2 and the steady rest material 5 are joined, the steady rest material 5 is moved from the inside to the outside. Toward the both sides 4b, 4b of the opening 4 (because the urging force acts toward the both sides 4b, 4b, it is possible to join more firmly.

As described above, according to the foundation structure 1 in the present embodiment, the pair of projecting portions 4f of the opening 4 and the pair of concave strips 5d of the flange portion 5b that can be elastically deformed are engaged with each other. The material 5 can be easily joined, and the movement of the steady rest material 5 in the vertical and lateral directions can be restricted.
Further, when the steady rest member 5 is joined to the stud 2, the flange portion 5 is compressed from the outside to the inside by the projecting portion 4 f, so that the distal end portion of the flange portion 5 b is part of the stud 2 as in the conventional invention. It is not necessary to form a gap (see FIG. 9C) for releasing 5e. Therefore, the stud 2 having higher strength than the conventional stud 101 can be formed.

  Moreover, since the recessed part 5d dented inward is formed in the flange part 5b of the steadying material 5, the rigidity of the flange part 5b becomes large, and the intensity | strength of the steadying material 5 can be raised.

In the present embodiment, not only the protrusion 4f and the recess 5d, but also the first contact part 4e and the base end part 5c, and the second contact part 4g and the front end part 5e contact each other. All sides and the side portion 4b of the opening 4 are in close contact with each other.
In the conventional invention, as shown in FIG. 9, the load 103 is in contact with the opening 103 because it is in contact with the opening 103 at two points apart from the distal end 109 and the proximal end 110. According to the present embodiment, since the load acts in a distributed manner, the bonding strength can be further increased.
Further, the side portion 4b of the opening 4 and the flange portion 5b are continuously in close contact with each other, so that the metal sound generated when the stud 2 and the steady rest 5 are rubbed can be suppressed and rattling can be prevented. .

  Further, the bonding strength can be further increased by increasing the contact area by bringing the lip portion 5f and the bottom side portion 4c into contact with each other. Further, by providing the lip portion 5f, as shown in FIG. 5B, the friction when the steady rest material 5 passes through the protruding portion 4f can be reduced. The metal sound due to friction can be reduced.

  The best embodiment of the present invention has been described above, but the present invention is not limited to this embodiment, and can be changed as appropriate without departing from the spirit of the present invention.
