Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention has a relatively simple structure, can be installed easily and quickly, can be well protected from rain after installation, and can be installed on ridge panels or walls. This invention relates to a folded-plate type door for roofs with an inverted L-shaped fastening part that can prevent thermal distortion occurring at ridges and the like by being attached to joint water cuts.

[Conventional technology and its problems]

Conventionally, when repairing the water side of the ridge of a folded type roof with a square bevel or a vertical bevel, mento doors were inserted and locked on both the left and right sides of the ridge cover board. This had the disadvantage that rainwater was likely to seep in through the folded type roof and around the side door. In addition, the ridge device for folding type roofs was generally installed with a ridge cover plate of an appropriate length in the longitudinal direction, and the ridge cover plate was attached to be expandable and retractable. Thermal expansion and contraction of this type of shingled roof causes metal fatigue of the ridge covering plate, which causes cracks to form in the middle of the roof, resulting in breakage and rainwater infiltration. This is requested.

[Means to solve the problem]

Therefore, as a result of intensive research in order to solve the above-mentioned drawbacks, the inventor of the present invention has developed the present invention by inverting the rear piece of the main door main body with a figure-7 cross section by using a top piece, a front piece, and a rear piece. It is formed into an inverted trapezoid shape so as to roughly follow the upper surface shape of the folding type locking roof having an L-shaped locking part, and the upper part of the front piece and rear side piece on one side of the main door main body is left in an inverted L shape. A shaped notch is formed, at least the edge of the vertical part of the inverted L-shaped notch is formed as an elastic inclined edge, and the lower part of the front piece and the rear end of the other side of the side door main body are formed. A side door is formed by forming an L-shaped notch, and the edge of the L-shaped notch and the edges of the other end of the front side piece and the rear side piece are formed as elastic inclined edges, or In the structure, a bent edge having a substantially doglegged cross section that holds the upper part of the inverted L-shaped locking part of a folding type locking roof is formed on one side end of the top piece, and By forming a locking edge with an abbreviated cross-section at the end that locks onto the upper part of the inverted L-shaped locking part of the folding type locking roof, it can be manufactured with a relatively simple structure and at low cost. By attaching it to a location near the water side of a folding type roof, it can be installed very easily and quickly, and after installation, it can be well protected from rain, and by attaching a ridge cover plate, etc. The purpose of this invention has been achieved by preventing the occurrence of thermal distortion due to thermal expansion and contraction of this type of roof and making it possible to improve rain protection at ridges, etc., thereby solving the above-mentioned drawbacks and achieving the object.

By forming the side door A in which the edge of the other end of the rear piece 1c is formed as an elastic inclined edge 6, 6,
First, it has a relatively simple configuration and is inexpensive, second, it can be installed easily and quickly, and third, after installation, the inverted L-shaped locking part _B1 becomes watertight and can be well protected from rain. Fourthly, by attaching the present invention to the ridge cover plate 18 or the wall joint cutout 19, it is possible to prevent thermal distortion occurring in the ridge portion, etc.

To explain the function and effect in detail, the folded type door A for the shim roof B has a relatively simple structure and shape, and its processing is simply pressed plate material, so it can be manufactured at low cost. . In addition, this side door A can be elastically fitted by simply fitting its inclined edges 4 and 6 into the inverted L-shaped locking portions B _{1 and} B on the water side side of the folding type locking roof B. It has the advantage of being extremely easy and quick to install. Furthermore, the elastic inclined edges 4 and 6 can be elastically locked and fitted to the sides of the inverted L-shaped fastening parts B ₁ and B ₁ by a so-called spring-tuck phenomenon, and it goes without saying that they are difficult to come off easily. , the watertightness of the inverted L-shaped tightening part B _in particular is superior due to the elasticity, and furthermore, since the rear side piece 1c has an inverted trapezoidal shape, the bottomed V-shape of the construction board 14 is improved. shaped part 14
It acts as a side door (b), prevents rainwater from entering the room, and improves rainproofing (watertightness).

Moreover, when the ridge cover board 18 and the wall joint cutout material 19 are attached via the side door A for the folding type roof B of the present invention, the architectural boards constituting the folding type roof B can be attached. 14 thermally expands and contracts as appropriate in the longitudinal direction in accordance with the outside temperature, and even if expansion and contraction appears at the ridge portion or wall joint portion of the folded type roof B, the ridge cover plate 18 and The wall joint cutout material 19 is attached to the roof via the elastic sloped edges 4 and 6 of the side door A, and the sloped edges 4 and 6 are placed on the inverted L-shaped fastening parts B ₁ and B ₁ . Since it is a resilient locking, the locking part B ₁ has an inverted L shape.
As a result, no thermal stress is generated in the ridge cover board 18, wall joint cutout material 19, and the construction board 14 constituting the folded type roof B, and no thermal stress is generated. can be reliably prevented from occurring. Moreover, the flattening phenomenon caused by thermal expansion and contraction can also be prevented. In such a configuration, in response to the vertical load of the ridge cover board 18 and the wall fitting cutout 19, the L-shaped notch 5 of the door A has an inclined edge 6 inside the inverted L-shaped locking part _B1. It can be held resiliently by being able to lock elastically. Furthermore, since the folded type roof B has a relatively high height and a large section modulus, it is subject to large thermal stress due to thermal expansion and contraction, and the plate cracking phenomenon occurs frequently. It is possible to reliably eliminate the plate sound phenomenon.

As described above, the bottomed V-shaped portion 14 of the construction board 14
The present invention has a great effect in that it functions as a side door (b) and can prevent thermal distortion occurring in the ridge portion by attaching it to the ridge cover board 18 or wall joint cutout 19.

In this case, on one side end of the upper surface piece a of the door main body 1 of the first invention, there is provided a substantially doglegged cross section that holds the upper part of the inverted L-shaped locking part B ₁ of the folding type locking roof B. By forming the side door A with the bent edge 8, the strength can be further improved. That is, as shown in FIG. 11, the inclined edge 4 is elastically placed on the upper surface side of the inverted L-shaped fastening part _B1 , and the bent edge 8 is placed in an inverted L shape.
Since it can be mounted by being bent so as to be crimped to the back side of the upper part of the shaped fastening part B ₁ , the bent edge 8 is held by this inverted L-shaped fastening part B ₁ , making it difficult to install against vertical loads. It can be made into something with much better strength. Since the other configurations are the same as those of the first invention, the same effects can be achieved.

Next, the invention of claim 3 (third invention)
In this case, on one side end of the upper surface piece 1a of the door main body 1 of the first invention, there is an inverted L of a folding type shim roof B.
By forming the surface door A with the locking edge 9 having an oval-shaped cross section that locks onto the upper part of the fastening portion _B1 , workability and strength can be further improved.

To explain this in detail, as shown in FIG. 12, the locking edge 9 is hooked onto the end of the inverted L-shaped fastening part _B1 while rotating on a virtual vertical plane, and the inclined edge 4 is Since the L-shaped fastening part B ₁ can be elastically attached to the upper surface side, the locking edge 9 can be locked and the inclined edge 4 can be elastically attached with almost one touch. The attachment work to the shape tightening part _B1 can be done even more easily and quickly. Furthermore, since the locking edge 9 can be locked to the inverted L-shaped fastening part _B1 ,
The strength of the installation against vertical loads can be further improved. Since the other configurations are the same as those of the first invention, the same effects can be achieved.

In addition, if the both side edges and the lower edge of the inverted trapezoidal rear piece 1c of the side door A are formed as inclined edges 1d, 1d, 1d with elasticity at an appropriate angle, the ridge part and the wall joint can be easily The sloped edge 1d, 1 has elasticity even when rainwater is sprayed strongly from below on the water side of the area.
d and 1d are rebounded against the side of the bottomed V-shaped portion 14b of the building board 14 by the so-called springback phenomenon within the elastic limit, so that the deflected inclined edges 1d, 1d, 1d It can be used as a dam to prevent rainwater from entering, allowing for better protection against rain. Furthermore, if a coating is provided on the surface of the building board 14 as a high-grade steel plate, the coating can be prevented from being damaged. Furthermore, if notches are formed in the corners of the lower ends of both sides of the front piece 1b, the plate can be placed on both shoulders of the bottomed V-shaped part 14b of the construction board 14 with the notches of the rear piece 1c. allows for stable installation.
