Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is extremely strong against positive and negative loads, eliminates the plate rattling phenomenon, and further reduces thermal expansion and contraction in the longitudinal direction of building boards for horizontal roofing. The present invention relates to a side-roofed outer enclosure that can be well adapted to the above-mentioned conditions.

[Conventional technology and issues]

The applicant has already developed various horizontally roofed enclosures such as roofs or walls that are roofed parallel to the eaves, and has improved workability,
Although it has excellent watertightness, it is not necessarily safe in terms of strength, the outer engaging portion is often unstable, and there are also disadvantages in that the plate rattle phenomenon often occurs.

Furthermore, there is a conventionally known side-roofed outer enclosure in which a hanger is locked to an inner engaging portion and is fixed thereto. This hanger is a partial piece, and because of the appropriate spacing in the longitudinal direction of the building boards for horizontal roofing (for example, about 30 cm to about 1 m), the top piece of the hanger is attached to the main plate near the outer engaging part. There is a gap corresponding to the thickness of the top piece of the hanger at a location other than the area where the hanger is in contact with the lower surface of the hanger. The outer engaging part is in a floating state, which not only makes it impossible to securely mount it, but also has the major drawback that it often comes off and scatters due to alternating loads caused by wind pressure loads such as storms.
There was also the serious drawback that due to wind pressure, etc., the crackling phenomenon constantly occurred due to the existence of a gap, which caused noise pollution. In addition, when constructing such a horizontal roofing enclosure, if a worker steps on the area between the inner and outer engaging parts, the area often becomes deformed and damaged. .
In addition, the conventionally known claw-shaped suspenders that are integrated with metal tarpaulins have the disadvantage that the strength of the base is particularly weak due to metal fatigue and the like. In addition, there were some models in which the rear pieces of the horizontal building boards were directly fixed with bolts, etc., without such hangers, but the horizontal building boards were not attached to the outside temperature in the longitudinal direction. When thermal expansion and contraction occurs in response to the above, thermal stress and strain will occur at the points fixed by bolts, etc. and other general parts exposed on the outer surface, causing deformation and strain on the horizontal roofing building boards, or at the fixed points. There were drawbacks such as damage to the Furthermore, when such thermal stress distortion occurs, it also becomes a cause of the plate ringing phenomenon.
In addition, if the locking part of the hanger is locked up to the tip of the inner engaging part, even if the horizontal building board and the hanger are independent, The drawback was that the board could not handle thermal expansion and contraction.

For this reason, there is a demand for the development of a horizontal roof enclosure with a simple structure that can strengthen the attachment of the engagement portion between the inner and outer engagement portions and eliminate the plate rattling phenomenon. Ta.

[Means to solve the problem]

Therefore, the inventor worked diligently to eliminate the above-mentioned drawbacks.
As a result of repeated research, the present invention has been developed by forming a bulging strip above one side edge of the main plate, forming a groove strip from the tip side of the bulging strip, and forming the bottom of the groove strip on the top surface of the main plate. An inner engaging part is formed on the upper side thereof, the tip side of which is rounded, and is spaced above the main plate surface, and below the other side edge of the main plate, an inner engaging part is formed. A horizontal construction board is formed by forming an engageable outer engaging portion, and the horizontal construction board is placed on a base material and its grooves are locked and pressed by the locking portion of the hanger. Then, the hanger is fixed to the base material, and the outer engaging part of the adjacent horizontal building board is engaged with the inner engaging part of the horizontal building board, and the top piece of the hanger is fixed. By adopting a horizontal roofing outer envelope that supports the lower surface of the main plate near the outer engaging part, it becomes extremely strong against positive and negative loads, eliminates the plate rattle phenomenon, and further improves the horizontal roofing structure. It can cope well with thermal expansion and contraction in the longitudinal direction of architectural boards, solves the above-mentioned drawbacks, and achieves its purpose.

〔Effect of the invention〕

In the present invention, a protruding strip 2 is formed above one side edge of the main plate 1, and a concave groove strip 3 is formed from the tip side of the protruding strip 2, so that the bottom of the concave groove strip 3 is formed on the main plate 1. An inner engaging portion 4 is formed on the upper side of the inner engaging portion 4, which has a rounded tip and is spaced above the surface of the main plate 1, and the inner engaging portion 4 is formed below the other side edge of the main plate 1. An outer engaging part 5 that can be engaged with the engaging part 4 is formed to form a horizontal building board A, and the horizontal building board A is placed on a base material C and the concave groove strips 3 are formed. The hanging part B is locked and pressed by the locking part 8a to fix the hanging part B to the base material C, and the horizontal building board A adjacent to the inner engaging part 4 of the horizontal building board A is fixed. outer engaging portion 5 of
By engaging the hanger B and using the top piece 9 of the hanger B to support the lower surface of the main plate 1 near the outer engaging part 5, the horizontally-roofed outer enclosure is firstly able to withstand positive and negative loads. Second, it can eliminate the plate noise phenomenon. Third, it can respond well to thermal expansion and contraction in the longitudinal direction of the horizontal building board A. Fourth, it is easy to engage in construction. It has the advantage of being extremely simple and quick.

To explain these effects in detail, first, the grooved strip 3 is locked and pressed by the locking part 8a of the hanger B to fix the hanger B to the base material C, and the top piece of the hanger B is fixed. By supporting the lower surface of the main plate 1 near the outer engaging part 5 of the adjacent horizontal building board A at 9,
The top piece 9 of the hanger B is not inserted between the inner engaging part 4 and the outer engaging part 5, and even if the hanger B is present, the inner engaging part 4 and the outer engaging part 5 are not inserted. A part or the whole can be tightly engaged over the entire length, and the groove strip 3 is locked and pressed by the locking part 8a of the hanger B, so that it can withstand alternating loads such as wind pressure loads, etc. This main plate 1
Even if strong wind pressure (negative) is applied to lift the object, the engaging part will not loosen.
It can be provided as a strong engagement part, and since the top piece 9 of the hanger B can support the lower surface of the main plate 1 near the outer engagement part 5 of the adjacent horizontal building board A, the main plate Even if the outer engaging part 5 of 1 (under water side) has a bulging shape at the engaging part, the entire engaging part is supported by the hanger B and is fixed to the base material C. It's getting old. In this way, a part or the whole of the inner engaging part 4 and the outer engaging part 5 are closely engaged over the entire length, and the grooved groove 3
is locked and pressed by the locking part 8a of the hanger B,
The support of the lower surface of the main plate 1 near the outer engaging portion 5 by the top piece 9 of the hanger B works synergistically to provide a horizontally roofed enclosure with extremely excellent strength. Therefore, it is completely possible to avoid deformation and damage to the engagement portion between the inner engagement portion 4 and the outer engagement portion 5 if a worker steps on the engagement portion during construction of the horizontal roofing outer enclosure. In this way, if the entire engagement part is strong and the inner engagement part 4 and the outer engagement part 5 can be partially or entirely engaged over the entire length, strong wind pressure loads etc. can be applied. It is also possible to reliably prevent the plate sound phenomenon. Therefore, as in the past, between the hangers, the outer engaging part is floating relative to the inner engaging part, which not only makes it impossible to install firmly, but also causes alternating loads due to wind loads, etc. This can solve all the major drawbacks that often occur when it comes off and scatters.

In addition, since the tip side of the inner engaging part is rounded and spaced above the surface of the main plate, the outer engaging part 5 can be easily hooked onto the inner engaging part 4 and rotated. The engagement can be carried out quickly, and an extremely excellent horizontal roofing enclosure can be provided as a whole.

Further, a bulging strip 2 is formed above one end of the main plate 1, and a concave groove 3 is formed from the tip side of the bulging strip 2, so that the bottom of the concave groove 3 is approximately on the upper surface of the main plate 1. Since they are in close contact, the bulging strip 2 has a suitable pipe-shaped cross section and has a large section modulus, and the engaging portion 8a of the hanger B is locked to the groove strip 3 continuous to the bulging strip 2. Therefore, even if a large external force is applied to the side roofing architectural board A, its locking strength can be significantly increased.

Furthermore, even if the horizontal roofing building board A is made of a highly elastic material (such as copper), or even if the area where the horizontal roofing building board A is installed has a large temperature difference, the horizontal roofing Even if the construction board A for construction is thermally expanded and contracted in the longitudinal direction in response to the outside temperature, in the present invention, the hanger B and the construction board A for horizontal roofing are not in a fixed state at all and are not pressed. However, each is in an independent state,
Even if the horizontal roofing building board A expands and contracts due to heat, it remains free at the hanger B, so no thermal stress is generated.
It is possible to create a side-roofed enclosure that does not cause deformation strain.
In particular, in the present invention, the end of the inner engaging part 4 is not locked to the locking part 8a of the hanger B, but the locking part 8a of the hanger B is locked to the grooved strip 3. Because it is pressed, the concave groove 3 and the locking part 8
Architectural board A for horizontal roofing, which can slide smoothly with A.
Even if it expands and contracts due to heat, it can be freely formed at the part of the hanger B. Therefore, the main plate 1 of the horizontal roofing architectural board A exposed on the outer surface can be formed with almost no deformation strain or the like. This allows for a strong connection structure in which almost no deformation or strain occurs even when subjected to external forces such as earthquakes. Therefore, it is possible to prevent the conventional decrease in strength due to thermal strain and the plate cracking phenomenon caused by thermal strain.

As described above, the structure is extremely simple and can be constructed at a relatively low cost, even though it has innovative effects such as strength, thermal expansion/contraction resistance, prevention of plate cracking, and ease of construction.

In addition, the protrusions 11a, 1 that abut the side ends of the bulging strips 2 of the main plate 1 of the horizontal roofing architectural board A are attached to the base material C.
If 6a are provided at regular intervals, the roofing pitch can be made accurately by making contact with the roofing holes 6a.

In particular, the longer the length of the architectural board A for horizontal roofing, the more the drawback that errors often occur on the left and right sides can be eliminated at once. Furthermore, metal support material 11
Even if the hanger B made of a separate member is used, it is not necessary to allocate the roofing pitches in the roofing direction, and the roofing can be done simply and quickly. Further, by pasting the heat insulating material 6 on the lower surface of the horizontal roofing building board A, it is possible to construct a horizontal roofing enclosure with excellent heat insulation performance. In addition, if a triangular or similar spacer portion 18 is formed between the inner engaging portion 4, the outer engaging portion 5, and the portion of the main plate 1 closer to the outer engaging portion 5, capillarity can be prevented and the flow into the interior can be prevented. Rainwater can be blocked even better.
