Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fitting roof that can be made into an extremely strong eave edge portion against wind pressure loads, can be made with a simple structure and at low cost, and can also respond well to thermal expansion and contraction.

Conventionally, a fitting roof has been separated from a fitting roof plate and a receiving fitting for fitting the fitting roof plate, and is provided to accommodate thermal expansion and contraction in the longitudinal direction of the fitting roof plate. By the way, wind and rain are particularly strong at the lower water side and gable side of the eaves, both in terms of design and experimental results, and such a fitted roof cannot withstand the strength. The wind force coefficient in architectural engineering is approximately several times higher at the eaves and gable sides of a roof compared to the middle part. On the other hand, the middle part of the roof becomes too strong, and when most of the roof work is done in the middle part, the construction cost of the entire roof rises. Furthermore, when the roof slope of the fitted roof is relatively steep, the wind force coefficient at the ridge portion is approximately several times that at the middle portion, and it is desired to increase this strength as well.

Therefore, as a result of extensive research in order to solve the above-mentioned disadvantages, the inventor has developed the present invention, which is a mating roof plate having chevron-shaped portions on both sides of the main plate, each having a chevron-shaped portion with engaging step portions formed on the left and right sides. In a mating roof that is fitted to a receiving metal fitting with a stepped portion to be engaged on a base material, at least at the eaves and gable side portions of the fitting roof, the mountain of the fitting roof plate is attached to the receiving metal fitting. By attaching the shaped part with a fixture, and by making the mountain-shaped part slidable in the longitudinal direction of the mating roof board against the base material even after it is attached, wind and rain blowing from the eaves etc. It is possible to create an extremely strong eave edge that can withstand even strong winds, has a simple structure and is inexpensive, and can respond well to thermal expansion and contraction, thus solving the above-mentioned disadvantages and achieving the purpose. be.

Hereinafter, the present invention will be explained based on embodiments shown in the drawings. 1, 2, etc. show examples of the fitting roof of the present invention, and A is a metal fitting roof plate having an appropriate length or length in the longitudinal direction, and the main plate 1 A chevron-shaped portion 2 on one side (right side in Fig. 10)

Alternatively, although not shown, attachment parts 5, 5 may be provided outward from the lower ends of both sides of the gate-shaped part 4. The engaging step portions 2a, 3a of the fitting roof plate A are formed so as to be engaged with the engaged step portions 4a, 4a.

The receiving fittings B are attached at predetermined intervals on the base material C on the upper part of the structure. The base material C is composed of only the purlins 6, 6..., or, as shown in the drawing, is formed of the top of the purlin 6 and a heat insulating board 7 such as a wood wool board or a foamed synthetic resin board laid thereon. Often. Furthermore, although not shown, it may be composed of a wooden main building 6, rafters, roof boards, etc. Further, in the embodiment, the receiving metal fitting B is attached onto the base material C using a fixing device 8 such as a drill screw, bolt, or nut.

When the receiving metal fitting B is attached to the base material C, there are cases where it is fixedly attached and cases where it is provided so as to be slidable. First, in order to fix the bracket B to the base material C, the eighth
As shown in FIGS. 9 and 9, the mounting portion 5 of the receiving metal fitting B is fixed at the through-hole portion thereof with a fastening device 8 such as a bolt or a nut. In addition, when attaching the receiving bracket B to the base material C in a slidable manner, as shown in FIGS. It is attached to the base material C so as to be able to slide appropriately within the range of this elongated hole 5a.

While the fitting roof plate A is placed between the receiving metal fittings B, the chevron-shaped portion 2 is fitted into the receiving metal fitting B, and the engaging stepped portion 2a and the engaged stepped portion 4a are engaged. , then the chevron-shaped portion 3 of the adjacent fitting roof plate A
is fitted so as to overlap the chevron-shaped portion 2 of the front fitting roof plate A, and its engagement step portions 3a, 2a are fitted, and at this time, the protrusion 2d of the chevron-shaped portion 2 and the chevron-shaped portion are fitted together. A gap 9 is formed between the part 3 and the protrusion 3d, and these steps are repeated one after another to form a fitted roof.

Then, at least at two locations, eave edge R ₁ and gable side R of the fitting roof R of the structure, the mountain-shaped portion ₂ of the fitting roof plate A is attached to the receiving metal fitting B so that drill screws, bolts, nuts, pins, etc. It is fixed with a fixture 10, and even after being attached, the mountain-shaped portion 2 is provided so as to be slidable as appropriate in the longitudinal direction of the fitting roof plate A. There are two examples of this embodiment, one in which the receiving bracket B is slidably provided and the fixture 10 is fixed as shown in FIGS. 4 to 6, and the other is As shown in Fig. 7, the bracket B is fixed,
This is a case where the receiving metal fitting B and the chevron-shaped portion 2 are slidably attached using a fitting 10. In this case, the fixture 10 is provided with a pin 10a and a washer 10b so as to be immovable in the vertical direction. The mountain-shaped portion 2 is slidably attached.

In addition, if the roof slope of the mating roof R is relatively steep, as _shown in Figs. The mountain-shaped portion 2 of the roof plate A is fixed with a fixing device 10 such as a drill screw, bolt, nut, pin, etc., and even if it is attached, the mountain-shaped portion 2 will slide appropriately in the longitudinal direction of the roof plate A for fitting. It is movable. Further, the ridge-shaped portions 2 and 3 of the fitting roof plate A are fitted to be slidable independently of each other as appropriate.

In the figure, reference numeral 11 denotes a pipe-shaped socket, which is used to prevent dents in the part of the heat insulating board 7, such as a relatively soft foamed synthetic resin board, when the bracket B is attached to the main house 6 with the fixing tool 8. It is intended to prevent 1
Reference numeral 2 denotes a dent prevention plate piece, which makes it easy for the receiving bracket B provided on the upper surface to slide, and securely presses the heat insulating plate 7 with a plurality of downward claws 12a formed around this plate piece. This prevents it from denting. A long hole 12b is also formed in the approximate center of the dent prevention plate piece 12 as required (see FIGS. 4 to 6). 13 is a ridge cover board, and 14 is a wall body.

Next, the effects will be explained.

Engagement steps 2a, 2 on both sides of the main plate 1 on the left and right sides
A fitting method in which a fitting roof plate A having chevron-shaped portions 2 and 3 formed with shapes a, 3a, and 3a is fitted onto a receiving metal fitting B with engaged step portions 4a and 4a on a base material C. In the roof R, the chevron-shaped portion 2 of the fitting roof board A is attached to the receiving metal fitting B at at least _two locations of the eave edge portion R ₁ and the gable side portion R of the fitting roof R using a fitting 10, Moreover, by providing the chevron-shaped portion 2 to be able to slide appropriately in the longitudinal direction of the mating roof plate A with respect to the base material C even after installation, first of all, the eave edge is extremely strong against wind pressure loads. _Second , it is _strong and can significantly reduce construction costs. Third, it has a simple structure and has good workability. Fourth, it is resistant to thermal expansion and contraction. It has many effects such as being able to respond well.

To explain the function and effect in detail, the fitting roof plate A
The mountain-shaped portion 2 is fitted and attached to the receiving bracket B at the _two locations of the eaves R ₁ and the gable side R of the fitting roof R, and is further attached to the receiving bracket B on the base material D with the mounting tool 10. The chevron-shaped portion 2 is attached so as to be immovable in the vertical direction, but movable in the horizontal direction.Thereby, from an engineering point of view, it is difficult to fit it into the base material C, which is the structural material of the structure. Eave part _R1 and gable side part of the roof R
If R ₂ is fixed, it will be the same, and the eave part R ₁ and gable side part R ₂ of the fitted roof R will be affected by the wind pressure load.
can be made extremely strong. That is, the strength due to fitting and the strength due to fixing work synergistically, making it possible to increase the wind force coefficient of the eave edge portion _R1 and gable side portion _R2 of the fitted roof R, thereby making it strong against wind pressure loads and the like. Therefore,
The wind force coefficient in architectural engineering is the eave edge R of the mating roof R ₁
and gable side R ₂ are several times larger than the middle part, but not only can this be easily met, but the middle part of the mating roof R can also be made of conventional thin material. It has sufficient strength, and can exhibit great effects in roof construction, etc., with almost no change in the construction cost of the entire roof. Moreover, even if the eave edge part R ₁ and the gable side part R ₂ are attached using the fixture 10, the chevron-shaped part 2 can be slid against the base material C in the longitudinal direction of the fitting roof board A as appropriate. By being movable, even if the mating roof plate A expands and contracts due to heat in its longitudinal direction depending on the outside temperature, it will slide appropriately in the longitudinal direction to absorb the thermal expansion and contraction. As a result, it is possible to provide the fitting roof plate A with an orderly fitting roof R that does not generate any thermal stress and does not generate thermal distortion or the like.
Further, even if the attachment tool 10 is provided separately, the structure of the present invention can be constructed mainly with only the mating roof board A, the number of members can be minimized, and the construction is almost the same as the construction of the conventional mating roof R. Yes, it has the advantage of superior workability and can be constructed at an extremely low price.
