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 wall panels of buildings, and more specifically, to construction materials that simplify the joining structure of the exterior materials. This invention relates to a joining structure for exterior materials.

(b) Conventional Background Conventionally, in the case of horizontally jointed structures of 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 face plates were to be joined, and these These lateral double-sided plates are connected by combining upper surface plywood that covers the upper surface between the face plates (for example, Japanese Utility Model Publication No. 56-51144 and Japanese 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 joining structure for architectural exterior materials that can be joined at low cost without increasing the number of parts to be joined.

(d) Summary of the invention In this invention, a connection piece provided in a concave shape is fixed to the top surface of a connection board with the open side facing horizontally, and one side edge of the face plate to be joined on the left and right sides on this connection board is attached. is formed with an inner fitting bent portion that fits in correspondence with the concave inner surface of the connecting piece, and a fitting direction opposite to the fitting direction of the above-mentioned inner fitting bending portion is formed on the other end edge corresponding to these fitting portions. The present invention is characterized by a joining structure for architectural exterior materials in which an outer fitting bent portion is formed to fit tightly, and these double-sided plates are continuously joined from side to side via the above-mentioned connection board.

(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. Just place it on the bottom between the boards. 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 fitting the left and right face plates to the connection piece on the connection board, respectively, and the work effort can be reliably reduced based on the reduction in the number of joining steps.

Furthermore, since the mating surfaces have mutually corresponding inner and outer fitting surfaces that are in close contact with each other, they are resistant to rainwater and the like. It also has good waterproof properties.

(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 has a large number of face plates 2 each having a horizontally long rectangular plate shape, arranged in a horizontal and vertical plane. A long and thin long plate 3 disposed vertically on the lower surface of the face plate 2 is fixed with screws 5 via fixing devices 4 for each face plate 2 on the upper surface to perform the vertical connection. .

Further, in the lateral direction, a connection board 6 disposed on the lower surface between the face plates 2 is used to perform lateral connection.

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, a lower edge engaging portion 8 is formed at the lower edge with the end thereof curved downward, and a connecting piece 9 having a longitudinally long U-shaped cross section is formed at the center of the upper surface. The connection board 9 is fixed by, for example, spot welding with its open surface facing sideways, and parallel grooves 10 for rainwater drainage are provided on both sides of the connection board 9. A bent portion 11 is provided in the lateral direction at the central portion of the connecting board 6, and the entire connection board 6 is slightly bent upward and downward with this bent portion 11 as a boundary. Reference numeral 12 denotes a notch for facilitating the 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 portion 14 is provided on the lower surface, which is bent and folded twice as much as possible, and is further fitted into one edge of the face plate 2 corresponding to the U-shaped inner surface of the connection piece 9 described above. Sideways U
A letter-shaped internal fitting bending part 15 is provided protruding from the upper surface, and the above-mentioned internal fitting bending part 1 is provided on the other side edge corresponding to these fitting parts.
Horizontal U that is mated from the opposite direction to the mating direction of 5.
A letter-shaped externally fitting bent portion 16 is provided protruding 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 configured in this way has
First, the inner bent part 15 of the face plate 2 on one side (right side in the figure)
In a state in which these are fitted inside, the externally fitting bent portion 16 of the other side face plate (left side in the figure) 2 is fitted outwardly to cover these fitting portions, and the fittings are fitted and connected so as to be attracted to each other from the left and right sides.

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 fitting portions 13 and 14 of the left and right face plates 2 and 2, respectively, and are connected without gaps during lateral connection.

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. The lower fitting insertion and engagement portions 14 of the face plates 2 to be connected are covered from above, and the connection is made by fitting to attract each other from above and below.

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 waterproofing, and the inner surface of these face plates 2 Rainwater will not infiltrate.

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 vertically divided and arranged to save the number of structural members. Fig. 6 shows a case in which the face plate 22 is integrally provided with a fixing tool, which is integrally molded at the time of molding the face plate to simplify the joining operation. Applicable to thin steel plates, etc.
