Description

[Detailed explanation of the idea] 【Technical field】

The present invention relates to a technology for connecting metal surface structural members used horizontally as roofing materials, exterior wall materials, etc.

[Background technology]

In the past, the side ends of the surface structure members were simply inserted into the clamping grooves, and the joint body was used to connect the surface structure members. did not exist). For this reason, during construction, the entire length of the side edge of the surface structure material was inserted tightly into the clamping groove, and there was no margin between the surface structure material and the joint body, so the surface structure material was exposed to solar heat, etc. When heated and thermal expansion occurs, the expansion of the surface structure material cannot be released, resulting in waving in the surface structure material.

[Purpose of invention]

The present invention was developed in view of the above-mentioned technical background, and its purpose is to simply bring the side edges of the surface structure material into contact with the insertion positioning pieces, thereby making it possible to remove the surface structure material during construction. To easily perform positioning and to prevent the surface structure material from waving by cutting an insertion positioning piece into the surface structure material when thermal expansion occurs in the surface structure material.

[Disclosure of invention]

The connection structure of the surface structure material of this invention has a flat cross section of approximately Ω.
A clamping groove 2 is formed by bending the joint body 1 over substantially the entire length on both sides of the joint body 1, and an end cover portion 5 that can be bent in a substantially U-shape is extended from one end of the joint body 1 toward the back side. , the clamping groove 2 is extended from a location corresponding to the inner inner part 6 of the clamping groove 2 on the inner surface of the end cover portion 5 toward the opening side of the clamping groove 2.
The insertion positioning piece 7 is projected so as to be retracted from the opening of the surface structure member 8, and the side ends of the surface structure members 8 are fitted into the holding grooves 2, and the surface structure members 8 are connected by the joint body 1. End bending part 9 provided at the end
is fitted into the end covering part 5, and the side end of the bent end part 9 is brought into contact with the tip of the insertion positioning piece 7 in a crossing manner, thereby achieving the above object. We have achieved this goal. Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Here, a case will be explained in which a metal roof plate material A is used as the surface structure material 8, but the surface structure material 8 can also be used as an external wall material etc. by being roofed vertically. Roofing sheet material A is shown in FIG. That is, the front end portion of the roofing material main body 10 is folded back toward the lower surface side in a substantially U-shape to form the end bent portion 9, and the roofing material main body 10 is folded back in a substantially U-shape.
A bent portion 11 is formed by making the rear end protrude toward the surface side in a bag shape with an inverted L-shaped cross section.The tip of the bent portion 11 is a connecting protrusion 12 that protrudes forward. U-shaped horizontal drainage ditch 13
are provided over the entire length of the left and right sides. Further, the center portion between the upper and lower parts of the roofing material main body 10 is very loosely bent in a dogleg shape over the entire left and right length. C is a waste board, and the waste board C is also very loosely bent approximately in the center from left to right in a dogleg shape, and a plurality of guide ridges 14 for draining water leakage are provided in the front and back direction on both sides. It is provided with a protruding structure, and both ends are folded upward to form a water stop part 17, which allows leakage water to drain to the front (in use, the front is lowered) without leaking to the side. ing. Further, the front end edge of the sacrificial board C is bent downward substantially vertically to provide a hanging piece 18, and the rear end edge is provided with an upstanding piece 19 raised substantially vertically upward. Joint B is formed by bending a steel plate cut into the shape shown in Figure 8 from a square original plate (the bending line is shown by a chain line), and the cutout from the original plate is small. . Clamping grooves 2 are formed in approximately the entire length of both sides of the joint body 1 which is bent into a flat cross-sectional shape of approximately Ω. The joint B is designed to be held in place, and the center portion of the joint B is bent very loosely into a substantially dogleg shape to match the roofing material main body 10. The insertion tongue piece 3 that extends laterally on the back side of the clamping groove 2 protrudes longer than the cover part 4 located on the front side of the clamping groove 2, and the front end of the insertion tongue piece 3 is attached to the side of the clamping groove 2. A sloping portion 15 is formed on the opening side so as to be slanted so as to recede rearward. An end cover part 5 is extended from the front end of the joint body 1 and is bent in a substantially U-shape toward the back side so as to be continuous with the cover part 4, and this end cover part has a flat annular cross section. An insertion positioning piece 7 protrudes toward the opening side of the gripping groove 2 from a location corresponding to the deep part 6 inside the gripping groove 2 at the center of the inner surface of the cover part 4. It is also short enough to draw people in. Further, due to the inclined portion 15, the width between the front end of the insertion tongue piece 3 and the inner surface of the end cover portion 5 is widened on the opening side of the holding groove 2. Further, the rear end of the joint body 1 is straight without being bent, and a flexible rubber packing 16 is adhered to the surface thereof. Therefore, during construction, the joint B is stacked on the center of the upper surface of the waste board C, and the side ends of the roofing material main body 10 are inserted into the clamping groove 2 from the sides of the joint B and the waste board C, and the roofing material is Connect the end bent portion 9 of the main body 10 to the joint B
The vertical piece 18 at the front end of the sacrificial board C is fitted into the end bent part 9 of the roof material main body 10 to connect the left and right surface structure members 8. When inserting the side end of the roofing material main body 10 into the clamping groove 2, the sloped portion 15 serves as a guide, so the bent end portion 9 of the roofing board material A is placed against the sloped portion 15 and inserted by sliding it. It's becoming easier to do. Furthermore, when the side end of the roofing material body 10 is inserted into the clamping groove 2, the side end of the bent end portion 9 crosses the tip of the insertion positioning piece 7 and stops, so that the entire side end of the roofing material body 10 is inserted. It is positioned so as not to come into contact with the inner deep part 6 of the clamping groove 2. Therefore, even if the roofing sheet material A expands due to heat, the insertion positioning piece 7 receives force and is crushed or cut by the end bent portion 9, absorbing the thermal expansion of the roofing sheeting material A. This can prevent the rippling phenomenon. Furthermore, after connecting the roofing board material A to the joint B, since the inclined part 15 at the end of the insertion tongue piece 3 of the joint B hits the end bent part 11 of the roofing board material A, the joint B
Even though the upper end of joint B is straight,
This prevents it from slipping forward and coming off. On the other hand, the gasket 16 at the rear end of the joint B is located between the bent portions 11 of the roof sheet material A on both sides, and both ends of the gasket 16 are brought into elastic contact with the bent portion 11 (the lower surface of the connecting protrusion 12). Furthermore, the bent portion 11 and the seal 16 are engaged with the bent end portion 9 of the upper roof sheet material A, and the connecting protrusion 12 of the lower left and right roof sheet materials A is connected to the upper roof sheet material. A end bent part 1
1 is sealed watertightly by a flexible packing 16.

[Effect of the idea]

Since the present invention is constructed as described above, it is possible to easily connect the surface structure materials by fitting the ends of the surface structure materials on both sides into the holding grooves, and furthermore, it is possible to easily connect the surface structure materials at the ends of the surface structure materials. The bent end portion is inserted into the end covering portion, and the side edge of the bent end portion is brought into contact with the tip of the insertion positioning piece so as to intersect, so that the surface structure material does not enter deep into the holding groove. It has the advantage that even if the surface structure material undergoes thermal expansion, the thermal expansion is absorbed by simply denting or cutting the insertion positioning piece, preventing the surface structure material from waving. .
