Description

[Detailed explanation of the invention] (a) Technical field of the invention This invention relates to architectural exterior materials such as those used for roofs and exterior walls of buildings, and more specifically, to construction materials that simplify the joining structure of the exterior materials. Regarding exterior materials.

(b) Background of the invention Conventionally, in the case of a horizontal joint structure among this type of architectural exterior material, lower plywood was laid on the lower surface of the double-sided board joint where the left and right boards were to be joined, The upper surface plywood covering the upper surface between these face plates is combined to connect these horizontal double-sided plates. (For example, Utility Model Publication No. 56-51144, Utility Model Publication No. 57-36741).

However, such a joining means has a problem in that the number of components to be joined between the double-sided plates is large, which increases the number of joining steps and requires a lot of labor, resulting in high costs.

(c) Purpose of the invention Therefore, the purpose of this invention is to provide a building exterior material that can be constructed at low cost without increasing the number of parts to be joined, and that is easy to construct.

(D) Summary of the invention In this invention, a U-shaped connecting piece is fixed to the upper surface of a connecting board with the open side facing horizontally, and the side edge of the face plate to be joined left and right on the connecting board in the width direction is provided with the A tongue piece to be inserted into the inside of the connecting piece is integrally arranged, and an externally fitting bent part is formed on the other side edge to fit and engage the connecting piece from the opposite direction, thereby forming a U-shaped connection between the double-sided plates. It is characterized in that it is constructed so as to be connected continuously from side to side via a connection board having two pieces.

(e) Effects of the invention According to this invention, since the connection board is provided with a connection piece that fits and connects the edge of the connection part of the face plate inside and out from the left and right, both sides of the connection board to be joined on the left and right sides are provided. By simply placing it on the lower side between the plates, the left and right face plates can be joined continuously.

Therefore, since bonding can be performed using only this connection board, there is no need for the upper plywood that covers the face plate bonding portion as is currently the case, and the number of bonded parts can be reduced.

In addition, the connection operation can be easily performed by simply inserting the left and right face plates into the connection piece on the connection board and fitting them to the other from the outside, reducing the number of steps required for connection. Work effort can be definitely reduced.

Furthermore, since the mating surfaces have mutually corresponding inner and outer fitting surfaces that are in close contact with each other, the sealing material has good waterproof properties against rainwater and the like.

(F) Embodiment of the invention An embodiment of the invention will be described below in detail based on the drawings.

The drawing shows an exterior material used for the outer surface of a building's roof, etc. As shown in Figure 1, this exterior material 1 consists of a large number of face plates 2 each having a horizontally large rectangular plate shape, arranged in a vertical and horizontal plane. A long plate 3 arranged vertically on the lower surface of the face plate 2 is fixed with screws 5 via fixing tools 4 for each face plate 2 on the upper surface to perform the vertical connection. Further, in the lateral direction, the connection in the lateral direction is performed by a connection board 6 disposed on the lower surface between the face plates 2, 2.

As shown in FIGS. 2 and 3, the above-mentioned connection board 6 is provided in the shape of a rectangular plate having a length corresponding to the longitudinal length of the face plate 2, and the upper edge of the rectangular plate shape is The U-shaped upper edge engaging portion 7 is bent inward.
is provided protruding from the upper surface, and a lower edge engaging portion 8 is formed on the lower edge with its end curved downward, and a U-shaped connecting piece 9 with a longitudinally long cross section is formed at the center of the upper surface, with the open side thereof being curved downward. The connection piece 9 is fixed by spot welding or the like in the horizontal position, and parallel projecting grooves 10 for rainwater to flow down are provided on both sides of the connection piece 9.

In addition, a bent portion 11 is provided in the lateral direction of the central portion of the connection board 6.
, and the entire connection board 6 is slightly bent upwardly and downwardly with this bent portion 11 as a boundary. 12
is a notch to facilitate bending.

The above-mentioned face plate 2 is an upper-fitting insert which is formed into a U-shape by inserting the upper edge engaging portion 7 of the connection board 6 laterally and folding it twice to engage with the lower edge of the face plate. An engaging portion 13 is provided to protrude from the upper edge of the face plate 2, and the aforementioned lower edge engaging portion 8 is laterally inserted into the lower edge of the face plate, and this lower edge is engaged with the upper edge of the face plate. A lower fitting insertion engagement part 14 which is bent and folded twice as much as possible is provided on the lower surface, and a tongue piece 15 is provided on one side edge in the width direction of the face plate 2 to be inserted into the U-shaped inner surface of the connection piece 9 described above. are integrally connected to each other, and the other side edge has a horizontally U-shaped outer fitting bending part 16 that fits and engages inside the connecting piece 9 and projects from the lower surface.

Reference numeral 17 denotes a bent portion, and by bending the entire face plate in the vertical direction with this bent portion 17 as a boundary, the upper and lower edges of these face plates 2 are overlapped with each other and connected sequentially and continuously in the vertical direction. It is set.

As shown in FIG. 3, the architectural exterior material constructed in this manner is obtained by first inserting the tongue piece 15 of the face plate 2 on one side (the right side in the figure) into the opening of the connection piece 9 on the connection board 6. Then, the externally fitting bent portion 16 of the face plate 2 on the other side (left side in the figure) is externally fitted to cover these fitting portions and connected.

At this time, the upper and lower edge engaging portions 7 and 8 of the connection board 6 are fitted into the upper and lower engaging portions 13 and 14 of the left and right face plates 2 and 2, respectively, during the lateral connection, and the connection is quickly made. .

In addition, as shown in FIG. 4, in the case of vertical connection, the fixing tool 4 is placed over the upper fitting part 13 of the face plate 2, fixed to the elongated plate 3 with screws 5, and then from the upper side. To make the connection, the lower fitting engagement portion 14 of the face plate 2 is covered from above, and the two are fitted to each other from above and below to be connected.

In this way, the vertical and horizontal face plates 2... are securely fitted and fixed, and the joint parts come into surface contact with each other against rain after the joint is completed, so it is suitable for waterproofness, and the inner surface of these face plates 2 Rainwater will not enter.

The above-mentioned face plate 2, connection board 6, etc. are plane-bonded using a metal plate such as an aluminum thin plate, a copper thin plate, or a thin steel plate, or a resin plate, and are used appropriately according to the conditions of use.

(G) Other Examples Figures 5 and 6 show other embodiments of this invention, of which Figure 5 shows a structure in which the small connecting pieces 29 are divided in the vertical direction to save the number of structural members. Fig. 6 shows a structure in which the face plate 22 is integrally provided with a fixing tool, which is integrally molded during molding of the face plate to simplify the joining operation. Applicable to thin steel plates, etc.
