Description

[Detailed description of the invention] The present invention is a connecting device for surface structure materials, especially when the roof or wall of a building or structure is constructed with horizontal surface structure materials. The present invention relates to a connecting device for surface structural members that can be extremely easily constructed and that also ensures that rainwater that seeps in through joints is discharged to the surface of the surface structural member located below.

An example of a structure for connecting joint portions of side-roofing surface structural members is described in Japanese Utility Model Application Publication No. 54-106615.

This idea folds the side edges of the surface structure material upwards,
Covers are inserted into both folded pieces of the surface structure members arranged on the left and right. Therefore, the cover can easily move along the side edges of the surface structure material and may come off.
Due to capillary action, rainwater that seeps through the joints may travel along the surface of the wasteboard and seep into the ceiling from the lower edge. Further, the cover cannot be inserted unless the folded pieces of the surface structure material are made with high dimensional accuracy at the construction site, which significantly reduces work efficiency.

The present invention was proposed in view of the above, and a scrap board is attached to the back side of the joint part of the side structural members lined up on the left and right.
In a connection device for surface structure materials in which a cover is attached to the surface of the joint portion, the surface structure material is provided with an engaging portion on the upper edge and a locking portion on the lower edge, and the waste plate is provided with a surface structure. A flat part is formed on the bottom edge, and a fitting part is provided on the lower edge to fit into the locking part of the surface structure material. A folding piece that is further folded back from the tip of the folding piece to the back side and made almost parallel to the above-mentioned folding piece forms insertion parts that open laterally on the left and right, and the outer surface of the locking part of the surface structure member is formed on the lower edge. A fitting part is provided to be attached to the surface structure material, a waste board is attached to the back side of the joint part of the surface structure material, and the insertion part of the waste board is fitted into the locking part of the surface structure material with the cover attached, The side edge of each side structure member is inserted into each insertion part of the cover, the fitting part of the cover is attached to the outer surface of the locking part of the face structure member, and the folded piece of the cover is attached to the flat part of the scrap board. It is characterized by being closely spaced.

The present invention will be explained below with reference to the embodiments shown in the drawings.When constructing the roof or outer wall of a building, for example, when the outer wall is used, the waste board 1 is generally a support material as shown in FIG. Among the metal surface structure members 3 laid outside the surface structure 2, this material is used on the back side of the joint portion of a pair of adjacent left and right surface structure materials 3, 3 laid at the same height. As shown in FIG. 2, this waste board 1 has a bent piece 4 bent toward the front surface on the upper edge, and a fitting portion 5 bent toward the back surface at the lower edge.
The bent portion 4 has an engaging portion 6 provided on the upper edge of the surface structure member 3.
is fitted into the fitting part 5 from the inside, and a locking part 7 provided at the lower edge of the surface structure member 3 is fitted from the outside. At the center of the surface of the waste board 1, there is a flat part 8.
in the vertical direction, and water return portions 9 are formed on the left and right sides of the flat portion 8.

On the other hand, the cover 10 applied to the surface of the waste board 1 is preferably formed by bending a single metal plate, for example.
This cover 10 has a fitting part 11 folded back on the back surface at least at the lower edge, and the locking part 7 at the lower edge of the surface structure member 3 is fitted into the inside. In some cases, it is also possible to provide a fitting part on the upper edge of the cover which is folded back onto the surface and which fits inside the upper edge engaging part 6 of the surface structure member 3.

On the back side of the cover 10, there is a fold-out piece 12 with the left and right side edges folded back and overlapped.
Further, a folding piece 13 is formed by folding back from the tip of each folding piece 12 to the back side, and an insertion part 14 that opens laterally by the folding piece 12 and the folding piece 13 is formed.
are formed on the left and right. Note that caulking material 15 may be stuffed into the inner end of this insertion portion 14.

In order to connect the joint parts of the surface structure members 3, 3 arranged on the left and right using the scrap board 1 and the cover 10 configured as described above, slide each surface structure material 3, 3 along the back surface of the cover 10, Cover 1 the side edge of the surface structure material 3
0, and the fitting part 11 of the cover is attached to the outer surface of the locking part 7 of the surface structure member 3. And the base part of the outer wall and roof and the surface structure material 3
A waste plate 1 is interposed between the joint part of the plate 1 and the fitting part 5 of the waste plate 1 is inserted into the locking part 7 of the surface structure material 3.

Therefore, the back side of the joint between the double-sided structural members 3 and 3 is covered by the waste board 1 and the front surface is covered by the cover 10, and both folded portions 13 of the cover 10 are placed on the surface of the waste board 1.

The above-mentioned connecting means is an example, and the side edge of each surface structure member 3 is inserted into the insertion portion 14 of the cover, and the fitting portion 5 of the waste board 1 is fitted into the locking portion 7 of the surface structure member 3. , and the fitting part 1 of the cover 10 is formed on the outer surface of the fitting part 5.
1 may be applied by any method.

In summary, according to the present invention, the cover has a fitting part provided on the lower edge attached to the outer surface of the locking part formed on the lower edge of the surface structure material, and an insertion part on the side of the surface structure material. The inserted edges provide strong support and will not come off or loosen even after exposure to rainstorms or over a long period of time. In addition, the cover constitutes an insertion part by a folding piece and a folding piece, and since the folding piece is almost parallel to the folding piece, the side edge of the surface structure material inserted into the insertion part is stably supported. Not only does it not come off from the insertion part, but the cover also does not come off from the surface structure material. Even if rainwater passes through the surface of the surface structure material and soaks into the inside of the cover, it will flow out into the insertion part of the cover or through the folded piece. Moreover, since the folded piece of the cover and the flat part of the scrap board are in close contact with each other,
In the completed state of construction, the cover can reliably support the waste boards, and no displacement occurs in their positions.

Therefore, even if rainwater enters the joints of the surface structure materials under any conditions, it will definitely flow out onto the surface of the surface structure materials below and will not seep into the ceiling space, resulting in extremely good rain control. be.

Furthermore, according to the present invention, screws and nails are not used,
Because it can be installed simply by inserting the cover into the side edge of the surface structure material and placing the waste board on the back side of the joint, work efficiency is extremely high, and work can be done in a short period of time even on large areas of external walls and roofs. It has extremely high practical value.
