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, and the outer engaging portion is often unstable, resulting in the frequent occurrence of flat rattle phenomena.

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 damage, thermal stress distortion occurs 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, Board A
However, it had the disadvantage of not being able to 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 drawbacks.
As a result of repeated research, we have developed the present invention, which has a concave groove in the middle above one side edge of the main plate, and has a generally U-shaped cross section with the opening side facing outward, and the U-shaped For horizontal roofing, an inner engaging part is formed bent so that the upper piece faces rearward, and an outer engaging part that can be engaged with the inner engaging part is formed below the other side edge of the main plate. As a construction board, place the construction board for horizontal roofing on the base material and press the concave grooves of the inner engaging part with the locking part of the hanger to fix the hanger to the base material. Then, engage the outer engaging part of the adjacent horizontal building board with the inner engaging part of the horizontal building board, and use the top piece of the hanger to pull the main board closer to the outer engaging part. By using a horizontal roofing envelope that supports the lower surface, it is extremely strong against positive and negative loads, eliminates the plate rattling phenomenon, and is also resistant to thermal expansion and contraction in the longitudinal direction of horizontal roofing construction boards. However, the above-mentioned drawbacks were solved and the objective was achieved.

〔Effect of the invention〕

In the present invention, the main plate 1 has a concave groove 2a in the middle above one side edge, and has a generally U-shaped cross section with the opening side facing outward, and an upper piece of the U-shaped section. An inner engaging part 2 is formed bent so that the main plate 1 faces rearward, and an outer engaging part 3 that can be engaged with the inner engaging part 2 is formed below the other side of the main plate 1. The construction board A for horizontal roofing is placed on the base material C, and the concave groove strips 2a of the inner engaging part 2 are locked and pressed with the locking part 6a of the hanger B. The hanger B is fixed to the base material C, and the outer engaging part 3 of the adjacent horizontal building board A is engaged with the inner engaging part 2 of the horizontal building board A, and the hanging Top piece 7 of child B
By using a horizontally-roofed outer enclosure that supports the lower surface of the main plate 1 near the outer engaging portion 3, firstly, an extremely strong mounting structure can be achieved against positive and negative loads, and secondly, It is possible to eliminate the plate rattling phenomenon, thirdly, it can cope well with thermal expansion and contraction in the longitudinal direction of the horizontal roofing architectural board A, and fourthly, the engagement construction can be performed extremely easily and quickly.

To explain these effects in detail, first, the groove strip 2a of the inner engaging part 2 is locked and pressed by the locking part 6a of the hanger B to fix the hanger B to the base material C. At the top piece 7 of the hanger B, the adjacent horizontal roofing construction board A
By supporting the lower surface of the main plate 1 near the outer engaging part 3 of the hanger B, the top piece 7 of the hanger B is not inserted between the inner engaging part 2 and the outer engaging part 3, Even if the hanger B is present, a part or the whole of the inner engaging part 2 and the outer engaging part 3 can be tightly engaged over the entire length, and the groove strip 2a of the inner engaging part 2 is locked and pressed by the locking part 6a of the hanger B, so even if alternating loads such as wind pressure loads or strong wind pressure (negative) that tries to lift the main plate 1 are applied, the engagement will not occur. This prevents the parts from loosening and provides a strong engaging part. In addition, the top piece 7 of the hanger B is connected to the main plate 1 near the outer engaging part 3 of the adjacent building board A for horizontal roofing. The main plate 1 can support the lower surface of the main plate 1.
Even if the outer engaging part 3 (under water side) of the holder has a bulging shape at the engaging point, the entire engaging point is supported by the hanger B and is fixed to the base material C. It's summery. In this way, a part or the whole of the inner engaging part 2 and the outer engaging part 3 are tightly engaged over the entire length, and the groove strip 2a is connected to the hanger B.
The hanging part B is locked and pressed by the locking part 6a.
The support of the lower surface of the main plate 1 near the outer engaging portion 3 by the top piece 7 acts synergistically to provide a horizontally roofed enclosure with extremely excellent strength. For this reason, while constructing the horizontal roofing outer enclosure, a worker must
It is also possible to completely eliminate the problem of deformation and damage to the outer engaging portion 3 and the engaging portion when the user rides on the engaging portion. In this way, if the entire engagement part is strong and the inner engagement part 2 and the outer engagement part 3 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.

Also, an inner engaging portion having a concave groove 2a in the middle and having a substantially U-shape in cross section with the opening side facing outward, and bent so that the upper piece of the U-shape faces rearward. 2. By engaging the outer engaging part 3, the main construction can be carried out by simply hooking and rotating the engagement, and the construction as a whole is extremely simple and quick. When the joint part 2 forms a U-shape and the upper piece 7 faces rearward, the close contact area between the inner engaging part 2 and the outer engaging part 3 increases significantly, more reliably withstands wind pressure loads, etc. In addition, it is possible to reliably prevent the phenomenon such as plate ringing.

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 2 is not locked to the locking part of the hanger B, but the hanger B is attached to the groove strip 2a at the intermediate position of the inner engaging part 2. Because the locking portion 6a is locked and pressed,
Smooth sliding between the concave groove strip 2a and the locking portion 6a is achieved, and even if the horizontal roofing building board A expands and contracts due to heat, the hanger B
It is something that can be done freely in certain places. Therefore, the main plate 1 of the horizontal roofing architectural board A exposed on the outer surface can be made to have 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 installed and constructed at a relatively low cost, even though it has innovative functions and effects such as strength, thermal expansion/contraction resistance, prevention of plate cracking, and ease of construction.

In addition, a protrusion 9a, which abuts the side end of the inner engaging part 2 of the main plate 1 of the horizontal roofing architectural board A, is attached to the base material C.
If the 14a are provided at regular intervals, the roofing pitch can be made accurately by contacting them and roofing. 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 9
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 4 on the lower surface of the horizontal roofing building board A, a horizontal roofing enclosure with excellent heat insulation performance can be constructed. In addition, if a triangular or similar spacer portion 16 is formed between the inner engaging portion 2, the outer engaging portion 3, and the portion of the main plate 1 closer to the outer engaging portion 3, capillarity can be prevented and the flow into the interior can be prevented. Rainwater can be blocked even better.
