Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting structure of surface structural materials constituting a roof-like roof surface or outer wall surface of a building.

[0002]

2. Description of the Related Art In the case of constructing a roof surface or an outer wall surface of a building using a certain length of a horizontal structure material for roofing, it is necessary to connect the edge portions of the left and right surface structure materials that are adjacent in the horizontal direction. I have to. As the connection structure of the surface structure material, there are cases where the surface is covered with a cover and cases where the surface is not covered with a cover, and the connection structure is selected depending on the appearance of the building and the structure of the surface structure material. As a conventional structure for connecting the surface structural material without covering the surface with the cover, the structure disclosed in Japanese Utility Model Application Laid-Open No. 52-68622 proposed by the present applicant, or Japanese Patent Application Laid-Open No. 61-36447 is used. There is a configuration described in the publication. According to the structure disclosed in Japanese Utility Model Laid-Open No. 52-68622, bent portions that can be fitted or engaged with each other are formed on the left and right edge portions of the surface structure material, and a groove portion is formed on the waste plate. Then, in a state in which the plane structure materials are connected in the lateral direction, the respective bent portions of the left and right plane structure materials adjacent to each other are engaged or overlapped with each other and mounted in the groove portion of the waste plate. Also, JP-A-61-36
In the configuration described in Japanese Patent No. 447, the left and right sides are formed by forming a folded-back bent portion and a bent piece that is stepped down at each end edge of the surface structure material and connecting the surface structure materials in the lateral direction. In this configuration, a bent piece is inserted into the bent portion of the surface structure material, and the bent portion is locked by the scrap plate.

[0003]

In the conventional structure described above, the structure disclosed in Japanese Utility Model Laid-Open No. 52-68622 has a surface structure material due to the temperature difference between summer and winter, or the temperature difference between strong sunshine and night. Since it is not possible to cope with the thermal expansion and contraction, the connecting portions of the surface structural materials may be displaced or float up, and in extreme cases, the connecting portions of the surface structural materials may be disconnected. Further, when a concentrated load such as an operator is applied near the connecting portion, the connecting portion may easily float up. Also, since the edge of the surface structure material is bent, its strength is higher than that of the plate portion of the surface structure material, but it is elastic like the plate part when it is deformed by the concentrated load of an operator. Because of the lack of restoration due to plastic deformation, plastic deformation may occur, which may impair the rain-sealing function and may deform the appearance, impairing the aesthetics of the building. Further, in the structure described in Japanese Patent Laid-Open No. 61-36447, a bent piece is inserted into the bent portion, but the structure of the bent portion is complicated and easily crushed, and the bent portion and the bent piece are Since the thickness is different, the bulkiness will be different at the left and right edges when stacking during storage, transportation by trucks, etc. As a result, deformation and damage of bent parts and bent pieces at both edge parts occur, Sometimes it can't be assembled at the construction site.
Then, in order to prevent such a defect, two surface structural materials may be combined into one set at different positions of both end edge portions to be superposed and bundled or packed with a wire or the like, but this is extremely troublesome. In addition to lowering productivity, transportation costs are also high, so it cannot be implemented in reality. Therefore, the structure is simple, and it is possible to cope with thermal expansion and contraction even during long-term use, and also has good rain storage. Has been requested.

Left and right surface structures adjacent to each other in the horizontal direction, each having a horizontally long surface structure material having a bent insertion portion, a waste plate having a flat portion in the center, and a connector having at least a hook-shaped holding portion. In the connecting portion of the material, the receiving portion of the one surface structural material and the insertion portion of the other surface structural material cooperate with each other to engage the holding portion of the above-mentioned connecting body, By arranging them in the shape-shaped portion, the receiving portion and the insertion portion of the left and right surface structural members have a margin in the width direction in the holding portion of the connection body, and the temperature difference between sunshine and non-sunshine, or in winter Thermal expansion and contraction can be sufficiently dealt with due to the temperature difference from the summer, and the connection part due to thermal expansion and contraction after construction Never lift or off occurs. Further, even if a worker walks in the connection portion of the surface structure material or in the vicinity thereof, or even if a concentrated load acts by installing the antenna for the television, the connection portion does not bend or shift. Moreover, the deformation does not cause rainwater to flow into the ceiling or damage the appearance of the building. Further, since the connecting body that substantially connects the left and right surface structural materials is arranged on the flat part of the waste plate, the positional relationship between the connection portion of the surface structure material and the waste plate is always maintained properly. Even if rainwater permeates from the connection part of the surface structure material, it is caught by the drainage plate and flows out to the surface of the surface structure material located on the lower side, so that it does not penetrate into the ceiling.

According to the present invention, the right and left surface structural members laterally adjacent to each other do not directly engage or fit the edge portions, but the receiving portion and the inserting portion cooperate with each other.
