Description

  The present invention relates to a fixing bracket for fixing a building panel such as an outer wall panel and a building member such as a building pillar or another outer wall panel, a fixing structure using the fixing bracket, and the fixing bracket. It relates to the fixing method used.

  In buildings including medium- and low-rise housing, outer wall panels made of lightweight aerated concrete (ALC) panels are attached to the beams that make up the frame, and at the corners, the pillars placed in the corners have the same material as the outer walls. The outer wall is constructed by attaching a corner panel.

When a panel such as an outer wall panel is attached to the casing, the work from the back side of the panel may not be performed after the casing is covered with the panel. Conventionally, as a coping method in such a case, a bolt is protruded in advance from the housing side, the bolt is inserted into an insertion hole provided in the panel, and a nut is fastened to the bolt. For example, there was a method using a drill screw or the like to be attached to.
In the former case, the mounting position of the panel is determined by the position of the bolt projecting from the housing side and the position of the bolt insertion hole of the panel, and the position of the bolt projecting from the housing side or the position of the panel bolt insertion hole There is a problem that it is difficult to correct the panel position when there is an error in manufacturing or construction in either of them. Even in the latter case, when the drill screw is screwed with an electric tool, if the panel is displaced and fixed, there is a problem that subsequent correction is difficult.

Patent Document 1 describes that a corner panel is mounted using a column fixing bracket provided with a fixing bolt that can rotate around an axis along a corner, but the adjustment of the mounting position of the panel is fixed. Since it is performed only by the rotation angle of the bolt, the degree of freedom is low, and for example, it is difficult to adjust the height of the mounting position after fixing the panel.
In Patent Document 2, there is a description of a floor support device having a support bolt that protrudes from a long hole portion of a pedestal portion and is movable in the longitudinal direction of the long hole portion. Since it is movable only in the longitudinal direction and the position of the support bolts must be determined before construction of the flooring material, the outer wall panel is constructed in a similar structure so that the position can be easily corrected. It is impossible to attach to.

With reference to FIGS. 1-4, preferable embodiment of the fixing metal fitting of this invention is described. In FIG. 1, the fixture 1 is composed of a plate-like pedestal 10 and a flanged bolt 20. 2 and 3 are a front view of the pedestal 10 and a plan view seen from above, respectively. The pedestal 10 is plate-shaped, the surface is a part facing the panel, and the back is the part for facing the building member surface. Referring to FIGS. 2 and 3, the pedestal 10 includes an abutting portion 11, a bolt holding portion 12 having a recessed back surface, and a bolt insertion hole 13 opened in the bolt holding portion 12. The abutting part 11 is a part for abutting on the building member surface on the back surface thereof. FIG. 4 shows the flanged bolt 20. The flanged bolt 20 includes a shaft portion 21 having a male screw cut and a plate-shaped flange portion 22 that extends in a radial direction perpendicular to the shaft portion 21 from one end of the shaft portion 21. The hooked bolt 20 is held by being loosely fitted to the base 10 with play, and the panel is fastened by the shaft portion 21.
Referring again to FIG. 1, the shaft portion 21 of the flanged bolt 20 protrudes from the bolt insertion hole 13 from the back surface to the surface of the pedestal 10, and the flange portion 22 of the flanged bolt 20 is included in the recess of the bolt holding portion 12 of the pedestal 10. Has been. The opening of the bolt insertion hole 13 is larger than the cross section of the shaft portion 21 of the flanged bolt 20 and smaller than the surface of the flange portion 22. Therefore, the shaft portion 21 of the flanged bolt 20 can be translated in two directions perpendicular to the direction in which the shaft portion 21 extends by a predetermined distance.
Further, the recess of the bolt holding portion 12 with respect to the back surface of the pedestal 10 has a bottom surface larger than the surface of the flange portion 22 of the flanged bolt 20, and a depth from the back surface of the pedestal 10 is larger than the thickness of the flange portion 22. large. Therefore, the flange portion 22 of the flanged bolt 20 is housed in the recess of the bolt holding portion 12 without projecting from the back surface of the base 10, and in the state of being included in the bolt holding portion 12 like the shaft portion 21, the shaft portion It can move by a predetermined distance in two directions perpendicular to 21.

The fixing bracket 1 of FIG. 1 is suitable for being attached to the surface of a corner of a housing such as a column corner, because the pedestal 10 is bent at a substantially right angle in the plate thickness direction as shown in FIG. Moreover, the bolt holding part 12 shown in FIG. 3 forms a dent on the back surface by projecting in a trapezoidal shape from the back surface of the contact part 11. Since the bolt holding portion 12 is raised with respect to the contact portion 11, when the base portion 10 is attached to the housing with the contact portion 11 being in contact with the housing surface, the surface side of the bolt holding portion 12 is raised.
