Description

[Detailed Description of the Invention] [Purpose of the Invention] (Field of Industrial Application) The present invention relates to a fitting for connecting building material plates, and particularly to a structure used for connecting actual joint type building material plates.

(Prior Art) Conventionally, fasteners for cement-based real-joint type building material boards formed by hollow extrusion as wall materials for buildings include, for example, flat plate-shaped substrates, as described in Japanese Utility Model Application Publication No. 56-34905. The board is bent into an O-shaped cross section and can elastically sandwich the building material board, and an underlay part extends from the base end of this bent part to the opposite side on the same plane as the board, and the board is attached to the building body. There is a known structure in which a protrusion with a V-shaped cross section on the connecting edge of one building material board is held between the nailed and bent portions, and this is fitted into a recess with a V-shaped cross section on the connecting edge of the other building material board. It is being

(Problems to be solved by the invention) In the above-mentioned actual joint structure, if the tip of the protruding part with a V-shaped cross section on the connecting edge of the concrete building material board is made thin and sharp, the tip part will be easily damaged, and the protruding part will be If it is thick and short, it will be difficult to insert it all the way to the inner end of the V-shaped recess in the other building material board, resulting in an incomplete connection.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, an object of the present invention is to provide a building material plate connection fitting that does not cause incomplete connection even if the degree of protrusion of the connection end of one building material board is reduced.

[Structure of the idea]

(Means for Solving the Problems) The building material plate connection fitting of the present invention has one end edge of a flat plate-shaped substrate slightly raised to form a first rising part, and the upper end of this first rising part. is bent toward the substrate side, and further bent to the opposite side via a second rising portion midway to form a bent portion having a U-shaped cross section, and from one end edge of the substrate, from the first rising portion to the bent portion. A cut and raised piece partially cut and raised is extended in the same plane as the substrate to form an extension part, and a V-shaped bent part is formed at the tip of the pair of spring pieces cut and raised from the second rising part. It is something.

(Function) The building material plate connection fitting of the present invention has a bent portion having a U-shaped cross section fitted into the protruding portion of the end face constituting the actual joint structure of the first building material plate constituting the wall surface of the building. When the second building material board is fitted into the concave groove on the end surface, the spring piece of the building material board protruding from the second rising portion is fitted to the inner end of the concave groove of the second building material board, and the first building material board to be actually spliced is fitted. , the protrusion of the second building material plate and the groove are closely fitted.

(Example) An embodiment of the present invention will be described with reference to the drawings.

Reference numeral 1 denotes a flat board made of a metal plate, in which a mounting hole 2 is formed, and a first rising part 4 is formed slightly rising from one end edge 3, and the upper end of this first rising part 4 is connected to the board. A first clamping plate part 5 is formed by bending to the first side, and a second rising part 6 is formed by raising the tip of the first clamping plate part 5 upward. The second clamping plate part 7 is formed by bending the upper end of the part 6 toward the first clamping plate part 5. A bent portion 8 having a U-shaped cross section and widening into a tapered shape is formed. Further, the length of the second clamping plate portion 7 is approximately 1/2 of the length of the first clamping body portion 5. Further, a cut and raised piece cut and raised from the center of one end edge 3 of the substrate 1 from the first rising portion 4 to the first clamping plate portion 5 is aligned at one end of the substrate 1 so that it is flush with the substrate 1. An extension portion 9 is formed extending from the edge 3. Further, a pair of cut and raised pieces cut and raised from a relative position of the lower end edge 10 of the second rising part 6 are made to protrude in the extending direction of the first clamping plate part 5, and a pair of spring pieces 11,1
1 is formed, and a V is formed upward at the tip of each spring piece 11.
A V-shaped head 12 is formed on each folded back portion.

Next, a method of forming a wall surface using the metal fittings of the above embodiment will be explained.

As shown in FIG. 2, a first building material board 14 made of hollow concrete is brought into contact with the surface of a building 13 so that its length direction is horizontal and its width direction is vertical. When the tapered U-shaped bent portion 8 is fitted into the protruding portion 15 having a trapezoidal cross section protruding from the center, the first rising portion 4 becomes the first rising portion 4.
is in contact with the end surface of the building material board 14, and the first
is inserted between the building material board 14 and the building 13. Then, the board 1 in contact with the building 13 is fixed to the building 13 with nails 16 driven through the mounting holes 2. Next, as with the first building material board 14, the second building material board 17 is made so that its length direction is horizontal, and the V-shaped groove 18 on the connecting end surface
When the bent portion 8 is fitted onto the protruding portion 15 of the first building material board 14, the second
The rising portion 6 is inserted halfway into the groove 18 of the second building material board 17, and the tip heads 12 of the pair of spring pieces 11 protruding from the second rising portion 6 are inserted into the V-shaped groove 18.
The bent portion 8 and the spring piece 11 are fitted to the connecting end formed by the protruding portion 15 and the groove 18 of the first and second building material plates 14 and 17 so as not to move. A gap 19 between the connection end surfaces opened to the outer surface between the first and second building material plates 14 and 17 connected in this manner is filled with caulking material and sealed.

[Effect of idea]

According to the present invention, a spring piece having a head at its tip is protruded inward from a bent part into which the protruding part of the first building material plate formed on one end edge of the board and connected by a real joint is fitted. By fitting this spring piece into the inner end of the groove of the second building material plate, the protrusion of the first building material plate can be inserted into the inner end of the groove of the second building material plate, that is, the first building material plate can be inserted into the inner end of the groove of the second building material plate. It is possible to reliably connect the tip of the protruding part of the first building material board without making it thinner.
