Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a structure in which the lower end of a concrete exterior wall panel is fixed to a building using mounting hardware.

(Prior Art) A structure in which an outer wall panel is fixed to a framework using fixing metal fittings is known from the idea described in Japanese Utility Model Application Publication No. 13304/1983 (hereinafter referred to as the first conventional example). This idea supports the edge of the outer wall panel with a roughly J-shaped support piece extending from a fixture attached to the framework.

Further, a structure in which the back side of the wall is supported by an upright piece that stands up from the tip of the fixture is known from a device described in Japanese Utility Model Application Publication No. 16322/1983 (hereinafter referred to as the second conventional example).

(Problems to be Solved by the Invention) In the first conventional example, the edge of the outer wall panel is only supported by a substantially J-shaped support piece. Therefore,
If the exterior wall panels were made of heavy concrete, they would not have sufficient strength and would lack stability because they would not be fixed with bolts.

The second conventional example has a structure in which the middle of the wall is fixed to a beam. Since the fixture and the beam are fixed simply by locking the locking pieces of the fixture, there is no strength, and no structure is shown to support the wall from below. Furthermore, the heads of the supports or bolts protrude outward from the wall, creating problems in terms of appearance as a fixing structure for external wall panels of buildings.

(Means for solving the problem) In order to solve such problems, the present invention has a structure in which the lower end of the concrete exterior wall panel is fixed to the frame of the building using a mounting bracket, and the frame is fixed to the frame of the building. It is formed by framing channel steel, and bolt holes are formed in the bottom plate of the horizontal members such as the middle crosspiece, upper chord member, and lower chord member, and the outer wall panel has multiple cross sections T in the vertical direction. A T-shaped dovetail groove is formed, and the head of the T-shaped dovetail groove is formed in the middle part of the outer wall panel in the thickness direction, and the legs are formed by cutting out the head part on the back side of the outer wall panel. The mounting bracket is composed of a fixing member and a receiving member, and the fixing member has a T-shaped connecting bolt serving as a leg attached to a locking plate serving as a head, and a nut is provided on the connecting bolt, and a receiving member is provided. The retaining member includes a board for attaching the receiving member to the horizontal member of the frame, a rear support plate of the exterior wall panel raised above one end of this base board, and a lower end of the exterior wall panel protruding from the bottom of one end of this base board. It is formed of a receiving plate with a roughly J-shaped cross section, and an engagement plate that protrudes downward from the other end of the board and engages with the shoulder of the horizontal member of the frame, and has a bolt through hole in the center of the board. The supporting plate is formed with a longitudinally long elongated hole, and the connecting bolt is inserted horizontally across the elongated hole, and
It is equipped with fixing bolts and nuts that are inserted into the aforementioned bolt holes to fix the board to the horizontal member of the frame assembly. The board is placed, and the engagement plate provided at the other end of the board is engaged with the shoulder of the horizontal member, and the bolt through holes formed in the board are matched with the bolt through holes formed in the bottom plate of the horizontal member. Then, the receiving member is fixed to the frame by tightening the nuts on the fixing bolts inserted through these bolt holes, and the lower end of the outer wall panel is placed on the receiving plate of the receiving member fixed in this way. The lower edge of the dovetail groove is placed, the back side of the outer wall panel is attached to the support plate of the receiving member, and the locking plate of the fixing member is inserted into the head of the dovetail groove formed on the outer wall panel. Then, this locking plate is engaged with the edge of the dovetail groove head, and the connecting bolt protruding from the leg of the dovetail groove to the back of the outer wall panel is horizontally inserted into the long hole of the support plate. It was inserted across the connection bolt and tightened by screwing a nut into this connection bolt.

(Function) The lower end of the concrete exterior wall panel is supported from below via the mounting bracket, and is pulled toward the back side (building side) and fixed to the framework.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.
