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. To provide a side-roofing outer enclosure which can be well adapted to the above-mentioned conditions, can accurately set the roofing pitch, and can be simply and quickly installed.

[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.

In addition, if you use a hanger made from a separate material from the metal tarpaulin, the pitch of the roofing in the direction of the roofing cannot always be accurately determined, and the longer the length, the more errors will occur on the left and right sides. It is inconvenient that it is difficult to roof the roof in parallel to each other, and there are conventionally known horizontal roofing enclosures in which hangers are locked to the inner engaging portions and are 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 engagement part is in a floating state, which not only makes it impossible to install it firmly, 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 the sounding phenomenon constantly occurred due to wind pressure and other factors, resulting in noise pollution.

In addition, while constructing such a horizontal roof enclosure, if a worker steps on the engagement part between the inner and outer engagement parts that have a gap, the part often becomes deformed and damaged. It was hot. 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, The drawback was that the board could not handle thermal expansion and contraction.

For this reason, we have developed a horizontal roofing system with a simple structure that can strengthen the installation of the engagement point between the inner and outer engaging parts, eliminate plate noise, etc., and make the roofing pitch accurate. There was a request for the development of an enclosure.

[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 protruding strip near one side edge of the main plate, and having a concave groove strip in the middle from the one side edge, so that the overall cross section has a substantially deformed M shape. an inner engaging part is formed, 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 to form a construction board for horizontal roofing; Place the construction board on the base material, lock its protruding strips to protrusions provided at regular intervals on the base material, and engage the concave groove strips on the inner engaging part with the locking parts of the hangers. Fix the hanger to the base material while pressing it firmly, and engage the outer engaging part of the adjacent horizontal building board with the bottom part of the horizontal building board, and then attach the hanger to the base material. By supporting the bottom surface of the main plate near the outer engaging part with the top piece, it becomes extremely strong against positive and negative loads, eliminates the plate rattling phenomenon, and furthermore The present invention has achieved its purpose by being able to cope well with thermal expansion and contraction in the directions, accurately setting the pitch in the direction of the roofing, and making the roofing process simple and quick, thereby solving the above-mentioned drawbacks and the like.

〔Effect of the invention〕

In the present invention, a protruding strip 1a is formed protruding near one side edge of the main plate 1, and a concave groove strip 2a is provided in the middle from the one side edge, so that the overall cross section has a substantially deformed M shape. An inner engaging part 2 is formed, and an outer engaging part 3 that can be engaged with the inner engaging part 2 is formed below the other side edge of the main plate 1 to form a horizontal architectural board A,
The construction board A for horizontal roofing is placed on the base material C, and its protruding strips 1a are engaged with protrusions 9a and 14a provided at regular intervals on the base material C, and the recess of the inner engaging portion 2 is The groove 2a is locked and pressed by the locking part 6a of the hanger B, and the hanger B is fixed to the base material C. Engage the outer engaging part 3 of the building board A so that the tip of the outer engaging part 3 comes into contact with the surface of the main plate 1, and use the top piece 7 of the hanger B to move the outer engaging part 3 closer to the outer engaging part 3. By supporting the lower surface of the main plate 1, firstly, it is possible to create an extremely strong mounting structure against positive and negative loads, secondly, the plate rattle phenomenon can be eliminated, and thirdly, it can be used for horizontal roofing construction. It can cope well with thermal expansion and contraction in the longitudinal direction of the plate A, and fourthly, the roofing pitch can be made accurately, and the roofing can be done simply and quickly.

To explain these effects in detail, first, the concave groove strip 2a of the lower leg 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, and then the hanger B
The top piece 7 of the hanger B supports the lower surface of the main plate 1 near the outer engaging part 3 of the adjacent horizontal building board A, so that the top piece 7 of the hanger B supports the inner engaging part 2 and the outer engaging part 3, and even if the hanger B is present, part or the whole of the inner engaging part 2 and the outer engaging part 3 are tightly engaged over the entire length. Since the concave groove 2a of the inner engaging portion 2 is locked and pressed by the locking portion 6a of the hanger B, the engaging portion loosens even under alternating loads such as wind pressure loads. In addition, since the protruding strips 1a of the horizontal roofing building board A are locked to the protrusions 9a and 14a on the base material C, the horizontal Even if strong wind pressure (negative) is applied to one main plate of the roofing architectural board A to lift the main plate 1, its protruding stripes 1a and protrusions 9a, 14
This can be reliably prevented by locking with a,
In addition, since the top piece 7 of the hanger B can support the lower surface of the main plate 1 near the outer engaging part 3 of the adjacent building board A for horizontal roofing, the lower surface of the main plate 1 near the outer engaging part 3 (water Even though the lower part (lower side) has a bulging shape at the engagement point, the structure is such that the entire engagement point is supported by the hanger B and fixed to the base material C, so it is structurally mechanically The entire engagement portion can be fixed to the base material C. 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 grooved groove 2a is connected to the locking part 6a of the hanger B. Locking and pressing, protruding strip 1
A and the protrusions 9a, 14a are in a locked state, and the top piece 7 of the hanger B supports the lower surface of the main plate 1 near the outer engaging part 3, which work synergistically to achieve extremely high strength. It is possible to provide a side-roofed enclosure with excellent performance. Therefore, it is completely possible to eliminate deformation and damage to the engaging portion between the inner engaging portion 2 and the outer engaging portion 3 when a worker steps on the engaging portion during construction of the horizontal roofing outer enclosure.
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.

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 expands and contracts thermally in response to the outside temperature in the longitudinal direction, 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.

Furthermore, in the present invention, the outer engaging part 3 is engaged with the inner engaging part 2 so that the tip of the outer engaging part 3 can come into contact with the surface of the main plate 1, so that rainwater does not get into the engaged part. It has the advantage that it is difficult to penetrate, can be well protected from rain, and can be firmly engaged.

In addition, since the architectural board A for horizontal roofing was placed on the base material C and its protruding strips 1a were locked to the protrusions 9a and 14a provided at regular intervals on the base material C, If you do the roofing, you will naturally be able to make the roofing pitch accurately.

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, even if the metal support member 9 and the hanger B are made of a separate member, it is not necessary to allocate the roofing pitches in the roofing direction, and the roofing can be done simply and quickly. In addition, although the claw-shaped hanger integrated with the metal tarp can ensure the pitch of the roofing, the base of the claw-shaped hanger has a drawback that its strength is particularly weak due to metal fatigue, etc. However, the present invention Now, this problem can be solved, and the hanger B has strength, and the roofing pitch can be made accurately.

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 compatibility, workability, and prevention of plate ringing.

In addition, if the heat insulating material 4 is adhered to the lower surface of the horizontal roofing building board A, a horizontal roofing outer enclosure with excellent heat insulation performance can be constructed. In addition, if a triangular intermediate 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 as shown by the dotted line in Fig. 4, capillarity can be prevented. This can prevent rainwater from entering the interior.
