Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a fixing metal fitting used mainly for attaching exterior wall panels to a framework in the construction of prefabricated houses.

BACKGROUND ART In prefabricated houses using the so-called framework construction method in which exterior wall panels are supported by frameworks, it is necessary to fix the exterior wall panels to the framework during construction. FIG. 1 shows a conventional fixing structure of this type of exterior wall panel. In the figure, 1 and 1 are a frame assembly of C channels arranged back to back adjacent to each other, and these frame frames are A binding bolt 2 inserted into each web 1a, 1a is attached to 1, 1. The outer wall panels 3, 3 are attached so that their respective ends are in contact with the outer surfaces of the respective frame assemblies 1, 1. At that time, first, as shown in the figure,
Insert an Ω-shaped bolt 4 whose center is bent into a U-shape into the gap 5 between each shaft assembly 1, 1, and lock the U-shaped bent portion 4a of the bolt 4 to the spelling bolt 2, Next, as shown in the figure, a stopper 7 equipped with a pair of rotatable holding pieces 6, 6 is fitted onto the outer end of the Ω-shaped bolt 4, and the nut 8 is inserted into the Ω-shaped bolt 4 from the outside. are screwed together to fix the stopper 7, and at the same time rotate the holding pieces 6, 6 outward to connect the holding pieces 6, 6 and the frame assembly 1, as shown in FIG.
The ends of the outer wall panels 3 and 3 are sandwiched between the outer wall panel 1 and the outer surface of the outer wall panel 1. In addition, reference numerals 9 and 9 in the figure are inner wall frames that are attached to the inner side of the frame assemblies 1 and 1, and these inner wall frames 9 and 9 are fitted onto the inner ends of the Ω-shaped bolts 4, and It is fixed by a holding plate 11 which is tightened with a nut 10.

Problems to be Solved by the Invention Therefore, in the above-mentioned conventional configuration, since the Ω-shaped bolts 4 are respectively locked to the binding bolts 2 of the frame assemblies 1, 1, the binding bolts 2 are always required. Moreover, the number of binding bolts 2 is required in accordance with the mounting position of each Ω-type bolt 4, which causes a significant increase in the number of man-hours for frame assembly work. In this case, the Ω-type bolt 4 could not be attached, and the panel could not be fixed arbitrarily depending on the location.

This invention eliminates these conventional drawbacks and
The purpose of the present invention is to provide a fixing metal fitting that does not require the above-mentioned bolts, greatly reduces man-hours during frame construction, and can be fixed at any position in the gap between frames. This was done as a.

Means for Solving the Problems In order to solve the above problems, the present invention provides a connecting rod that is inserted into the gap between the frameworks, and a connecting rod that is arranged on one side of the framework and that is connected to the side surface. and a stopper provided with a presser piece that holds the panel edge between them, and one end side of the connecting rod is inserted into a through hole formed in the stopper, and the connecting rod is inserted into the through hole. and a tool for rotating the connecting rod. In addition to providing an engaged portion, the other end side of the connecting rod is capable of being inserted into the gap between the frames from the panel side, and comes into contact with the side of the frame opposite to the panel side. In order to achieve this, the present invention is characterized by providing an elastic locking pin having a length greater than the width of the gap.

Embodiment Hereinafter, the configuration of the present invention will be explained based on an illustrated embodiment. In FIGS. 3 to 6, 21
is a fastener having the same structure as the conventional example, and this fastener 21 is rotatably attached to a board 22 and to both upper and lower ends of this board 22 by hexagon socket head bolts 23, 23. It consists of holding pieces 24, 24, and these holding pieces 24, 24 are
Anti-rotation pieces 25, 25 are integrally provided on the substrate 22, protruding from both the upper and lower ends of the substrate 22, and protruding outward in parallel from both the left and right ends of the substrate 22, respectively. On the other hand, 26 is a round bar-shaped connecting rod, and one end of this connecting rod 26 is rotatably inserted into a through hole 27 formed in the center of the substrate 22,
Furthermore, a hexagonal over-rotation prevention washer 28 and a hexagon socket head bolt 29 as a retaining member are integrally fixed to the end projecting from the stopper 21. Furthermore, this connecting rod 26 has a male thread 30 formed at the other end thereof, and this male thread 30
A locking pin 31 made of an elastic material such as spring steel is inserted and attached in the diametrical direction at a position closer to the center.

To explain the method of fixing an exterior wall panel using the fixing fittings 33 having the above-mentioned configuration, first, in FIG. In this way, the joint sheet 32 is adhered. In this state, the fixing metal fitting 33 is inserted into the gap 5 through the joint sheet 32 from the tip of the connecting rod 26 on the male thread 30 side with the locking pin 31 vertically, and this male The screw 30 and the locking pin 31 are made to protrude to the opposite side of the frame assembly 1. At this time, the fixture 33 is
Since it is held by the joint sheet 32 without falling downward, there is no need to support it all the time, making the work easier. After that, a tool such as a screwdriver is engaged from the outside into the hexagonal hole of the hexagon socket head bolt 29 at the end of the connecting rod 26, and the connecting rod 26 is tightened.
When rotated by 90 degrees, the locking pin 31, which is longer than the width of the gap 5, becomes horizontal and the shaft assembly 1,1
The fixing metal fitting 33 is securely held in that position by the elastic action of the locking pin 31. In this embodiment, the hexagonal hole corresponds to the engaged portion of the present invention. After that, the holding piece 2 of the stopper 21 is removed as in the conventional case.
4, 24 outward, and the pressing pieces 24, 2
The bolts 23, 23 supporting the panels 4 are screwed in, and the installation of the outer wall panels 3, 3 is completed in the same manner as before (Fig. 5). Further, inner wall frames 9, 9 are fixed to the inner ends of the connecting rods 26 by presser plates 34 and nuts 35, as in the conventional case. In addition, as shown in FIG. 6, the over-rotation prevention washer 28 has a hexagonal shape with both symmetrical corners 36, 36 at right angles.
Only in the 90° range from the position where one side 37 that intersects at this corner 36 abuts on the one rotation prevention piece 25 to the position where the other side 38 abuts on the other rotation prevention piece 25. It is designed to be able to rotate,
As a result, when the connecting rod 26 is rotated from a state in which the locking pin 31 is vertically inserted into the gap 5, the locking pin 31 can only be rotated until it becomes horizontal. When attached to the frame assembly 1, the locking pin 31 is always held at a position perpendicular to the gap 5. Further, if the hexagon socket head bolts 23 of the holding piece 24 and the hexagon socket head bolts 29 of the connecting rod 26 are of the same size, there is an advantage that they can be operated with the same tool. In addition, in the above, the holding piece 24 may be formed integrally with the stopper 21 and not rotated as in the embodiment.

Effects of the invention As described above, according to the invention, the connecting rod is inserted into the gap between the frame members from the end on the locking pin side, and then,
This metal fitting can be attached to the shaft assembly simply by turning the connecting member 90 degrees and locking the locking pin to the shaft assembly, and unlike conventional bolts that are locked to the shaft assembly, there is no need for such a binding bolt. As a result, the number of construction man-hours and number of parts for frame construction work is significantly reduced, making it possible to carry out the work at low cost.It also has the effect of being able to be installed at any position in the gap between the frame frames, and allowing the panel to be fixed at any position as long as there is a gap. It will be done.
