Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a structure in which the midway portion of a hollow external wall panel is attached to a floor beam of a building.

(Prior Art) Conventionally, there has been an idea disclosed in Japanese Utility Model Application Publication No. 13624/1983, which discloses a structure for attaching a concrete exterior wall panel to the frame (framework) of a building.
In this conventional example, a steel material with high bending strength is attached to the hollow part of a hollow extrusion molded plate over almost the entire length, and a nut welded to the steel material and a corresponding bolt hole in the hollow extrusion molded plate are connected to the nut welded to the steel material. Therefore, it is attached to the structure using bolts.
The bolt is tightened to the body angle. Further, the body flange is welded to an angle piece or a channel piece, and this angle piece or channel piece is screwed to the structure.

(Problem to be solved by the invention) In the conventional example, the body rim is welded to an angle piece or channel piece, and this angle piece or channel piece is screwed to the structure, which requires troublesome welding work. Furthermore, since the only means for fixing the angle piece or channel piece to the structure is to screw the sides together, it has been difficult to support an exterior wall panel with a large load. Furthermore, the attachment between the body rim and the panel required bolting, which was troublesome.

(Means for Solving the Problems) In the mounting structure of the hollow exterior wall panel of the present invention, the middle part of the concrete panel, which has a vertically penetrating hollow part inside, is fixed using a mounting bracket. The mounting structure is such that the support plate that is installed on the floor beam and the mounting plate that locks the external wall panel are integrally formed so that the cross section is approximately L-shaped. At least two bolt through holes are formed, and one bolt shaft through hole is formed in the mounting plate, and the bolt shaft with an engaging member attached to the tip is inserted into the bolt shaft through hole formed in the mounting plate. A nut is screwed into this bolt shaft protruding toward the support plate, and the engaging member is drawn toward the mounting plate by this nut, and the mounting bracket formed in this way In this case, the support plate is placed perpendicularly across the floor beam from the outdoor side to the indoor side, and the bolts are inserted from each bolt hole formed in the support plate into the bolt hole formed in the floor beam. The mounting bracket is attached and fixed to the floor beam by inserting the screw into the bolt and tightening and fixing the support plate and the floor beam with nuts screwed into the bolts, and the mounting bracket is attached to the floor beam in the middle of the outer wall panel to be installed along the floor beam. A vertically long hole communicating with the hollow part is formed in the back of the part, and the engaging member attached to the tip of the bolt shaft described above is inserted into this vertical hole, and when the bolt shaft is rotated, this engaging member engages with the hollow part. The outer wall panel is pulled and fixed to the mounting plate by being engaged with the inside and tightening a nut screwed into the bolt shaft.

(Function) A support plate is placed on top of the floor joist and crossed orthogonally from the outdoor side to the indoor side, and the support plate and the floor joist are fixed with bolts.

In this way, the exterior wall panels are attached to the mounting brackets fixed to the floor beams.

A vertically elongated hole is formed from the midway back of the outer wall panel to the hollow portion, and an engaging member provided at the tip of a bolt shaft inserted through the mounting plate is inserted into the hollow portion from the vertically elongated hole. When the bolt shaft is rotated to lock the engaging member inside the hollow part, and the nut is screwed into the bolt shaft protruding from the mounting plate and tightened, the outer wall panel is drawn to the mounting plate by the engaging member. . In this way, the exterior wall panel is attached to the floor beam via the attachment fittings.

(Example) The configuration of the present invention will be described below with reference to the drawings.

The outer wall panel 5 attached and fixed along the floor beam 1 is made of concrete. The dimensions of the exterior wall panel are, for example, width: approx. 50 cm, height: approx. 300 cm, and thickness: approx.
It is 6cm. The attachment relationship of the exterior wall panels 5 changes depending on the shape and dimensions of the building. That is, the upper and lower ends or other intermediate parts of the outer wall panel are attached and fixed to a framework (not shown) that is the framework of the building. The outer wall panel 5 has a hollow portion 5a that vertically penetrates inside.

The mounting bracket 2 connects the mounting plate 22 and the support plate 21 to approximately L.
It is integrally formed into a letter shape. A bolt shaft through hole 23 is formed in the mounting plate 22, and an engagement member 2 is formed at the tip.
4 is inserted into the bolt shaft through hole 23 such that the engaging member 24 is located in the opposite direction to the support plate 21. Bolt shaft through hole 23
A nut 26 is screwed onto a bolt shaft 25 protruding from the support plate 21 toward the support plate 21, so that the engaging member 24 is pulled toward the mounting plate 22.

The support plate 21 has at least two bolt holes 2.
7 is formed, and a bolt 28 is inserted into the bolt through hole 27 (in a direction parallel to the mounting plate 22). The bolt 28 is provided with a fixing nut 30.

The mounting bracket 2 configured as described above is fixed to the floor beam 1 in the following manner.

A support plate 21 is placed on the floor beam 1 so as to cross orthogonally from the outdoor side to the indoor side. A bolt through hole 11 is formed in the flange of the floor beam 1 to correspond to a bolt through hole 27 formed in the support plate 21. The bolt through holes 27 formed in the support plate 21 are matched with the bolt through holes 11 formed in the flange of the floor beam 1, and the bolts 28 are inserted into these bolt through holes. Bolt 2 protruding from the flange of floor beam 1
The support plate 21 is attached and fixed to the floor beam 1 by screwing the fixing nut 30 into the hole 8. In this way, the mounting bracket 2 is attached to the floor beam 1.

Mounting bracket 2 fixed to floor beam 1 in this way
Attach exterior wall panel 5 to.

Hollow part 5 from back part 5b in the middle part of outer wall panel 5
The engaging member 2 is provided at the tip of the bolt shaft 25 that is inserted into the mounting plate 22 and formed with a vertically elongated hole 5c that reaches the length a.
4 is inserted into the hollow part 5a from the vertically elongated hole 5c. When the bolt shaft 25 is rotated to lock the engagement member 24 inside the hollow portion 5a, and the nut 26 is screwed into the bolt shaft 25 protruding from the mounting plate 22 and tightened, the engagement member 24 locks the outer wall. Panel 5
is attracted to the mounting plate 22. In this way, the outer wall panel 5 is attached to the floor beam 1 via the attachment fittings 2.

In addition, the outer wall panel 5 is made of concrete,
The panel may be made of not only inorganic materials, but also a mixture of inorganic and organic materials, or foamed concrete.

Further, it is preferable that long grooves are formed in the vertical direction at appropriate intervals in the back portion 5b of the outer wall panel 5 to allow ventilation in the vertical direction on the inner surface of the wall. Further, the hollow portion 5a is formed in consideration of the strength of the panel, but it is formed so that the outer wall panel 5 can be made as lightweight as possible.

(Effects of the invention) As described above, according to the invention, the midway portion of the hollow external wall panel can be attached to the floor beam extremely easily and efficiently.

Specifically, since the concrete exterior wall panel has a hollow part inside, the engaging member provided on the mounting plate of the mounting bracket is inserted into the vertical hole formed from the back of the hollow part to the hollow part. Since it is fixed, the exterior wall panel and the mounting bracket can be easily connected without damaging the appearance of the exterior wall panel and without using fixing means such as bolts. The vertically elongated hole may be formed from the back of the outer wall panel to the hollow part.

Since the floor beam and the mounting bracket are fixed with screws, the fixing work is easy, and the support plate can be easily fixed so as to be correctly orthogonal to the floor beam. Furthermore, even when a large load such as a concrete exterior wall panel is placed on the mounting bracket, it can be securely held and fixed.
