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-roofed outer enclosure that can respond well to various conditions, accurately set the roofing pitch, and furthermore enable simple and quick roofing.

[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, when using a hanger made of a separate material from the metal tarpaulin, it is not always possible to accurately set the pitch in the direction of the roofing, 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 a serious drawback in 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, we have developed the present invention by providing an inner engaging portion above one side edge of the main plate with a rounded tip and bent at a position above the main plate surface, and A projecting strip facing the direction 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 board for horizontal roofing construction, and the board is used for horizontal roofing construction. The hanging plate is placed on the base material, its protruding stripes are locked to protrusions provided at regular intervals on the base material, and the protruding strips are locked and pressed with the locking portion of the hanger to hang the hanger. It is fixed to the base material, and the outer engaging part of the adjacent building board for horizontal roofing is engaged with the inner engaging part of the building board for horizontal roofing, and the top piece of the hanger is used to connect the outer engaging part to the inner engaging part of the building board for horizontal roofing. By using the horizontal roofing outer envelope to support the lower surface of the main board on the side, it becomes extremely strong against positive and negative loads, eliminates the plate rattling phenomenon, and further improves the longitudinal direction of the horizontal construction board. It can cope well with thermal expansion and contraction of the roof, and the roofing pitch can be set accurately, and the roofing can be completed simply and quickly, thus solving the above-mentioned drawbacks and achieving the purpose.

〔Effect of the invention〕

In the present invention, an inner engaging part 2 is provided above one side edge of the main plate 1 and has a rounded tip and is bent and spaced apart from the surface of the main plate 1, and extends from the rear end in the longitudinal direction. A projecting strip 3 facing the main plate 1 is formed, and an outer engaging part 5 that can be engaged with the inner engaging part 2 is formed below the other side of the main plate 1 to form a construction board A for horizontal roofing. A construction board A is placed on a base material C, and its protruding strips 3 are locked to protrusions 12a and 17a provided at regular intervals on the base material C, and the protruding strips 3 are used to lock the hanger B. The hanger B is fixed to the base material C by locking and pressing at the part 8, and the outer engaging part 5 of the horizontal building board A adjacent to the inner engaging part 2 of the horizontal building board A is fixed. By using the horizontally roofed outer enclosure in which the top piece 10 of the hanger B supports the lower surface of the main plate 1 near the outer engaging part 5, firstly, it can withstand positive and negative loads. Secondly, it can eliminate the plate noise phenomenon. Thirdly, it can cope well with thermal expansion and contraction in the longitudinal direction of the horizontal building board A, and fourthly, it can improve the roofing pitch. The roofing can be done accurately, and the roofing can be done simply and quickly.

To explain these effects in detail, first, the protruding strip 3 is locked and pressed by the locking part 8 of the hanger B to fix the hanger B to the base material C, and the top piece 1 of the hanger B is fixed.
By supporting the lower surface of the main plate 1 close to the outer engaging part 5 at 0, the top piece 10 of the hanger B is placed between the engaging part of the inner engaging part 2 and the outer engaging part 5. is not inserted, and a part or the whole of the inner engaging part 2 and the outer engaging part 5 can be closely engaged over the entire length in the longitudinal direction, and the protrusion of the horizontal roofing building board A Since the strips 3 are locked to the protrusions 12a and 17a on the base material C, the main plate 1 of the horizontal building board A
Even if an alternating load such as strong wind pressure (negative) or wind pressure load that tries to lift the main plate 1 is applied to the part, the protruding strip 3 and the protrusions 12a and 17a are locked together. There is no possibility of the joint becoming loose, and it can be provided as a strong joint.
In addition, since the top piece 10 of the hanger B can support the lower surface of the main plate 1 near the outer engaging part 5 of the adjacent horizontal building board A, the lower surface of the main plate 1 near the outer engaging part 5 (water Even if the lower side (lower side) has a bulging shape at the engagement location, the entire engagement location is supported by the hanger B and is 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 5 are tightly engaged over the entire length, and the protruding strip 3 is locked and pressed with the hanger B. The synergistic effects of As a result, it is possible to provide a horizontally-roofed outer enclosure having engagement points with extremely high strength. Therefore, it is completely possible to eliminate the problem of deformation and damage to the engagement portion between the inner engagement portion 2 and the outer engagement portion 5 when a worker steps on the engagement portion during construction of the horizontal roofing outer enclosure. When the entire engagement area is made strong in this way, it is possible to reliably prevent plate rattling phenomena even when strong wind pressure loads are applied. 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, the inner engaging portion 2 has a rounded tip and is bent at a position above the main plate 1 surface.
By engaging the outer engaging portion 5 of the adjacent building board A for horizontal roofing, it is possible to engage easily and quickly by just hooking and rotating it, and as a whole, it is possible to create a horizontal roof with extremely excellent workability. Can be made into a roof enclosure.

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 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. Even though the horizontal roofing building boards A are thermally expanded and contracted, they remain free at the hanger B, so no thermal stress is generated and no deformation strain occurs. Can be made into a roof enclosure. In particular, in the present invention, the tip side of the inner engaging part 2 is not locked to the locking part of the hanger B, but the protruding strip 3 and the rear part of the inner engaging part 2 are connected to the hanger B. Since the protruding strips 3 and the hangers B can slide smoothly, the architectural board A for horizontal roofing
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.

In addition, the horizontal roofing building board A was placed on the base material C, and its protruding strips 3 were locked to the protrusions 12a and 17a 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, metal support material 12
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. In addition, although the claw-shaped suspenders integrated with the metal tarpaulin can ensure the pitch of the roofing, the base of the claw-shaped suspenders has the disadvantage of being particularly weak in strength 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 6 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. Also, as shown by the dotted line in Figure 3, when the outer engaging part 5 of the adjacent horizontal building board A is engaged with the inner engaging part 2, the inner engaging part 2 and the outer engaging part If the hanging portion 5a of the main plate 1 and the portion of the main plate 1 close to the outer engaging portion 5 form a substantially triangular interspace portion 19, capillary phenomenon can be prevented and rainwater can be prevented from entering the inside. Can be shut off reliably.
