DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for a polycarbonate resin roofing material comprising a plurality of polycarbonate resin roofing materials.

[0002]

2. Description of the Related Art Polycarbonate resin has excellent weather resistance, impact resistance, and transparency, and can be used as a roof material that can be used as a light source in large buildings such as pools, warehouses, gymnasiums, and station buildings.
It is widely used in small buildings such as bus stops, bicycle sheds, and carports.

Conventionally, a roofing material made of a polycarbonate resin used as a roofing material has been mainly of a flat plate shape. And, as an installation structure of such a flat roof material, when forming an arched roof, rafters are finely assembled on the main house assembled on the foundation steel frame to form squares, and the entire roof is arched And a metal fixed frame such as aluminum is assembled on each square, and a flat roof material is fitted into the fixed frame, or a polycarbonate resin roof material is pressed down around the fixed frame by the fixed frame. Structures are common.

[0004] The roofing material mounting structure is not limited to the arched shape of the target building, and may be a flat-shaped roofing material made of a polycarbonate resin, even if the roofing shape is a single-flow or double-flow roof. Is used, basically the same mounting structure as described above is employed.

[0005]

However, in the above-mentioned conventional mounting structure for a polycarbonate resin roofing material, a metal fixing frame must be used on the main roof in addition to the rafters. There is a problem in that the area is occupied and the lighting efficiency is reduced. In addition, since a lot of labor is required for the work of assembling the rafters and the work of attaching the fixed frame, there is a problem that the working efficiency is reduced and the cost is increased. Furthermore, since the entire roof becomes heavier due to rafters and fixed frames, it is necessary to build a foundation steel frame that is robust enough to withstand the weight of the roof. This also takes time for foundation work, further reducing work efficiency and increasing costs. Is caused. Furthermore, in order to prevent water leakage, it is necessary to fill a gap between the fixed frame and the roofing material with a sealing material, and the mounting work becomes complicated.

In order to solve the above-mentioned conventional problems, the inventors of the present invention have proposed a method in which a flat polycarbonate resin plate is bent in advance to form rising edges along both side edges. It is to be mounted on the main building roof, with the rising edge of the polycarbonate resin roof material extending in a direction perpendicular to the main building, and arranged side by side in the longitudinal direction of the main building. Alternatively, a holding member is mounted so as to be orthogonal to the main building, and the rectangular resin or the holding member made of polycarbonate is arranged so that the rising edges are attached to both sides of the square reinforcing member or the holding member. We have previously proposed a mounting structure for a polycarbonate resin roofing material that can be mounted to the resin roofing material with bolts and nuts.

In the above-mentioned structure, the roofing material can be mounted without installing a member that hinders daylighting, such as a conventional rafter or a fixed frame, so that the lighting efficiency can be relatively reduced without impairing the transparency of the roofing material. It is possible to increase the height, and also does not require the cumbersome work of assembling the rafters and the fixed frame, so that the work efficiency is improved and the cost can be considerably reduced, but the square reinforcement is orthogonal to the main building. Because of the mounting structure, the above effects cannot always be obtained sufficiently from the viewpoint of lighting and work efficiency and cost.

Further, hook bolts for attaching the square reinforcing member to the main building, bolt nuts used for attaching the square reinforcing member to the roofing material made of polycarbonate resin, and the like are exposed to the outside, so that the appearance of the object to be constructed is improved. Not only does the appearance worsen, but also external stress and internal strain stress concentrate on the connecting bolt holes provided in the polycarbonate resin roofing material, making it easier for cracks to occur in the polycarbonate resin roofing material itself, There is a possibility that the durability of the film may be reduced.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a structure for mounting a roofing material made of polycarbonate resin, which solves the above-mentioned conventional problems, further increases the daylighting rate, reduces costs, has high appearance quality, and has high durability. And

[0010]

In order to achieve the above-mentioned object, the present invention provides a method for manufacturing a roof material comprising a plurality of polycarbonate resin roofing materials having rising edges extending on both side edges thereof. Attachment of a polycarbonate resin roofing material that connects the rising edges of adjacent roofing materials with a connecting fixture when installing the roofing materials side by side in the longitudinal direction with the extending direction of the rising edge portion of the roofing material orthogonal to the main building. In the structure, the connecting fixture is formed of a metal member having a vertical cross-section, a fixed connecting blade on the lower left and right sides, and a connecting wing on the upper left and right sides, and is fixed to the purlin with the fixed wings. Along with
After arranging the rising edges of the adjacent roofing materials so as to abut each other so as to sandwich the connecting wall from both sides, the connecting wings are bent downward to restrain the rising edges, and then the rising edges of the rising edges are restrained. Over the entire length, a cross-section consisting of an elastic bent portion and an open leg wall having an engagement portion bent inward at the lower end extending downward and to the left and right thereof is covered with a substantially inverted U-shaped steel plate cap material, The gist is a mounting structure of a roofing material made of polycarbonate resin, wherein an engaging portion is engaged with a tip of the connecting wing.

The mounting structure of a polycarbonate resin roofing material of the present invention uses a polycarbonate resin roofing material having rising edges extending on both side edges, and is connected by adjacent rising edges. Therefore, it is possible to install roofing materials without assembling rafters, fixed frames, etc.

Further, since a troublesome work of assembling the rafter and the fixed frame is not required, the work efficiency can be improved and the cost can be reduced.

Further, since a fixture such as a hook bolt or a bolt nut which is exposed and perceived is not used, a construction object having a good appearance can be obtained.

Furthermore, since there is no need to provide bolting holes for connection at the rising edge of the roofing material made of polycarbonate resin, the risk of cracks due to external stress or internal strain stress is extremely reduced, and the roofing material made of polycarbonate resin is reduced. The original strength of the material can be kept high.

Are connected by a connecting fixture (5) at the rising edges (4) adjacent to each other in the longitudinal direction of the purlin (2) in a state where the extending direction is orthogonal to the purlin (2). 6) to be attached.

Specifically, the polycarbonate resin roofing material (3) is provided with rising edges (4) on both side edges of a polycarbonate resin plate (P) as shown in FIG. The part (4) is provided by bending the side edge of the flat plate in the longitudinal direction by, for example, a bending method.

Regarding the dimensional specification of the polycarbonate resin roofing material (3), the thickness (s) is 1 to 5 m.
m and the width (w) are suitably in the range of 0.5 to 2 m, and the height (h) of the rising edge (4) is suitably in the range of 10 to 50 mm. Here, the thickness (s) is 1 to 5 mm.
When the length is less than 1 mm, the bending of the polycarbonate resin plate (P) becomes large, so that the interval (s) between the purlins (2) is used.
This is because it is necessary to shorten the length and increase the number thereof, and if it exceeds 5 mm, not only the weight increases but also it becomes difficult to bend the rising edge (4). The reason why the width (w) is set to 0.5 to 2 m is that if the width (w) is less than 0.5 mm, the number of the roofing materials (3) per unit area of the roof increases, the number of connection points increases, and the man-hour for mounting work increases. It is a factor that hinders the appearance of the building (1).
If it exceeds m, the weight increases and construction work becomes difficult. Furthermore, the height (h) of the rising edge (4) is 10 to 50 mm.
When the length is less than 10 mm, the connecting fixture (5) described later is used.
Connection becomes uncertain, and if it exceeds 50 mm, there is no longer any mounting advantage, and especially when the object roof shape is an arch shape, the rising edge (4) of the roof material (3) is buckled. However, it cannot be used as a roofing material as it is.

It is set in the range of ６０60 mm. The length (C) of the connecting wing (5c) is determined by the thickness of the rising edge (4), ie, the thickness (s) of the roofing material (3) made of polycarbonate resin and the thickness of the packing material (P). This is set in consideration of (p) and the height (h) of the rising edge portion (4), and in relation to a cap material described later that engages with the tip of the connecting wing (5c).

Further, as shown in FIG. 5, the cap member (6) has an elastic bent portion (6a) and an engaging portion (6b) (6b) which extends right and left downward and is bent inward to the lower end. ) Is formed of a long object made of a steel plate having a substantially inverted U-shaped cross section composed of the open leg walls (6c) and (6c). Due to the repulsive force of the elastic bending portion (6a), the engaging portion (6b) engages with the open leg walls (6c) (6c).
(6b) always acts so as to reduce the width (v), and the engaging portions (6b) (6b) serve as connecting wings (5c) for restraining the rising edges (4) (4). ) (5c) engages with the tip, and serves to maintain the bent state of the connecting wings (5c) and (5c). The cap member (6) itself is combined with the connecting fixture (5) and covers the rising edge (4) over its entire length to exhibit a waterproof effect.

The cap member (6) is obtained by, for example, bending a long steel plate having a thickness of 0.8 mm along the length direction. At this time, the engaging part (6b)
The width (v) between (6b) is approximately 5 mm, and the shape of the engaging portions (6b) (6b) is not only a hook shape as shown in FIG. 5 but also, for example, as shown in FIG. Wrapped shape or the like is selected, and the folded length (m) or (n) is 2 mm
In either case, it is important that the cap member (6) be shaped so as not to come off when engaged with the tip of the connecting wing (5c) (5c).
