DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a polycarbonate resin roof comprising a plurality of polycarbonate resin roof materials.

[0002]

2. Description of the Related Art Polycarbonate (hereinafter referred to as "PC") resins have excellent weather resistance, impact resistance, and transparency.
It is widely used from large buildings such as station buildings to small buildings such as bus stops, bicycle sheds, and carports.

Conventionally, a plate made of polycarbonate resin used as a roofing material is mainly of a flat plate shape. When an arched roof as shown in FIG. 9 is formed by using such a flat roof material, a rafter (3) is placed on a purlin (2) assembled on a foundation steel frame (1). It is necessary to form a square by assembling it finely, form an arch as a whole roof, further assemble a fixed frame made of aluminum etc. on each square, and fit a flat roof material (4) into this frame to perform construction. It is customary.

The roof shape is not limited to the arch shape, and even if the roof shape is a single-flow or double-flow roof, when a flat PC resin roofing material (4) is used, the basic shape is used. Will be constructed in the same manner as above.

[0005]

However, in the above-mentioned conventional roof made of PC resin, a rafter (3) must be incorporated on the main building (2), and a fixing frame must be further fitted.
These occupy a considerable area on the roof, and there is a problem that the lighting efficiency is reduced. In addition, since much work is required such as the work of assembling the rafter (3) and the work of fitting the fixed frame, there is a problem that the working efficiency is reduced and the cost is increased. Furthermore, the weight of the entire roof is increased due to the rafters (3) and the fixed frame. Therefore, it is necessary to construct a solid foundation (1) that can withstand the weight of the roof. This causes a problem of lowering the cost and increasing the cost.

The present invention solves the above-mentioned problems of the prior art, provides a high daylighting rate, and enables a low-cost, efficient PC.
It is intended to provide a resin roof.

[0007]

In order to achieve the above object, the polycarbonate resin roof of the present invention is provided with rising edges having a height of 10 to 50 mm along both side edges ,
It is provided with a plurality of roofing materials made of polycarbonate resin having a thickness of 1 to 5 mm and a width of 0.5 to 2.0 m , and the length of the roofing material is the length of the main building on the main roof of the building. A plurality of the rising edges corresponding to each other are arranged side by side along the purlin length direction in a state perpendicular to the height direction, and the corresponding rising edges between the adjacent roofing materials are connected to each other, and the rising edges of the roofing materials are connected. The gist is that which is connected and fixed to the corresponding purlin.

The roof made of PC resin of the present invention utilizes the rising edges formed along both side edges of the roof material made of PC resin to connect the roof materials and fix them to the purlin. Roofing can be performed without assembling members that hinder lighting, such as rafters and fixed frames. Therefore, a high daylighting rate can be obtained without impairing the transparency of the PC resin.

[0009] Further, since the complicated work of assembling the rafters and the fixed frame is not required, the work efficiency can be improved and the cost can be reduced. In addition, since the roof weight can be reduced, the labor required for the foundation work can be reduced. Thus, the working efficiency and the cost can be further reduced.

Since the roofing material has rising edges on both sides thereof, sufficient strength can be ensured for the roofing material itself, and for example, the initial roof shape can be reliably maintained, and damage to the roofing material can be ensured. Can be prevented.

Further, according to the present invention, since a roof material having a simple shape in which rising edges are provided on both side edges of the PC resin plate is used, bending can be easily performed. For this reason, especially when the roof shape is an arch shape, for example, PC
The radius of curvature can be reduced compared to resin folding, etc.
It can be applied to a wide range of applications from large buildings to small buildings.

In the present invention, it is preferable to adopt a structure in which a reinforcing material is interposed between corresponding rising edges between adjacent roofing materials. That is, when adopting this configuration,
The strength of the entire roof can be further increased, and defects such as deformation of the roof shape and damage to the roof material can be more reliably prevented.

Further, in the present invention, it is preferable to adopt a structure in which a waterproofing material such as a packing or a sealing agent is provided between the corresponding rising edges between adjacent roofing materials. That is, when this configuration is adopted, waterproofing between the roof materials can be reliably achieved.

Further, in the present invention, it is desirable to adopt a configuration in which the rising edges connected to each other between adjacent roofing materials are covered with a cover. That is, when this configuration is adopted, waterproofing between the roofing materials can be more reliably achieved, and the joint between the roofing materials can be concealed, so that the appearance can be improved.

FIG. 1 is a perspective view showing a building to which a polycarbonate (PC) resin roof according to a first embodiment of the present invention is applied, and FIG. 2 is a side view thereof. As shown in both figures, the roof part of this building is formed in an arch shape and is constructed using a roofing material (10) unique to the present application.

The roofing material (10) is formed by processing a PC resin plate as shown in FIGS. 5 and 6, and both side edges are bent to form a rising edge (11). It is formed and curved in an arch shape in the length direction following the roof shape.

As shown in FIGS. 1 and 2, a plurality of such roofing materials (10) are arranged side by side along the longitudinal direction of the purlin (2). The corresponding rising edges (11) and (11) are connected to each other as described later, and the rising edges (11) of each roofing material (10) are fixed to the purlin (2) by appropriate means described later. Then, the building roof is built.

Hereinafter, the roof of this embodiment will be described in detail.

FIG. 3 is a sectional view taken along line III-III of FIG. 2, and FIG. 4 is a sectional view taken along line IV-IV of FIG. As shown in both figures, a plurality of purlins (2) made of lip channel steel are assembled in an arch shape on the foundation steel frame (1) of the building, and the roof shape is imposed on the purlin (2). A reinforcing material (20) made of square steel curved in an arch shape is disposed along a direction orthogonal to the length direction of the purlin (2). This reinforcement (2
0) is a state in which the hook bolts (51) and (52) are vertically penetrated, and the hook portions of the hook bolts (51) and (52) are engaged with the lip pieces and the lower surface area of the purlin (2). In the screw shaft part of the hook bolt (51) (52) upper part,
The nuts (61) and (62) are fixed to the purlin (2) by being fastened. In addition, a plurality of reinforcement members (20) are arranged corresponding to each of a plurality of roofing materials (10) to be constructed.

Packing (3) is provided on both sides of the reinforcing material (20).
0), the roofing material (10) having the above configuration is arranged. And in that state, one roofing material (10)
Rising edge (11), packing (30), reinforcing material (2
0) and the rising edge (11) of the other roofing material (10)
Then, a bolt (53) is penetrated, and a nut (63) is fastened to the screw shaft portion of the bolt (53) from the opposite side. In this way, the corresponding rising edges (11) sandwich the reinforcement (20) and the roofing (10) reinforces the reinforcement (2).
0) is fixed to the purlin (2). The packing (30) is arranged continuously along the rising edge (11) of the roofing material (10).

The cover (40) for covering the periphery of the reinforcing material (20) is made of U-shaped steel, and is similar to the roofing material (10) and the reinforcing material (20) in the longitudinal direction. It is curved and formed in an arch-like shape in accordance with. The stiffener (20) is arranged such that the cover (40) accommodates the stiffener (20) and the roofing rising edge (11) in its U-shaped groove.
The hook bolts (51) and (52) are arranged on the cover (40) so that the screw shafts of the hook bolts (51) and (52) penetrate from below. Then, in this state, the nut (6) screwed to the screw shaft portion of the hook bolt (51) (52)
4) The cover (40) is fixed to the purlin (2) via the reinforcing material (20) by pressing the (64) against the upper surface of the cover (40).

In the construction procedure of the roof made of PC resin, first, the reinforcing material (20) is fixed on the main house (2). Subsequently, the roofing material (10) is attached so as to sandwich the reinforcing material (20) via the packing (30), and then the cover (4) is attached.
0) is fixed.

As described above, according to the roof made of PC resin of the present embodiment, the roof material (10) is provided by using the rising edges (11) provided on both side edges of the roof material (10) made of PC resin. Since the connection between them and the fixing to the purlin (2) are intended, the roof construction can be performed without assembling a large number of members that hinder daylighting, such as rafters and fixed frames, to the purlin as in the related art. Therefore, P
A high lighting efficiency can be obtained without impairing the transparency of the C resin. In addition, the roof construction does not require the troublesome work of assembling rafters and fixed frames, so it is possible to improve work efficiency and reduce costs, and furthermore, the roof weight can be reduced, so spending on foundation work The labor can be reduced, and the working efficiency and cost can be further reduced.

Further, since the roofing material (10) has a simple shape only by bending both side edges of the PC resin plate, an arched roofing material (10) is formed as in the present embodiment. In this case, for example, it is possible to easily bend as compared with a case where a folded plate made of PC resin is bent. For this reason, for example, the radius of curvature can be reduced, and it can be applied to a wide range of applications from large buildings to small buildings. In addition, roof material (10)
Since the both side edges are bent, sufficient strength can be secured for the roofing material itself, and for example, the initial roof shape can be maintained for a long time, and damage to the roofing material can be reliably prevented.

Further, in this embodiment, the roof material (1)
Since the reinforcing material (20) is interposed between 0), the rigidity of the entire roof can be further increased, and defects such as deformation of the roof shape and damage to the roof material can be more reliably prevented.

In this embodiment, a packing (30) is interposed between adjacent roof materials (10),
Covers the seam area between adjacent roofing materials (10) (40)
As a result, waterproofing between adjacent roofing materials (10) can be ensured, and problems such as rain leaks can also be reliably prevented.

Further, the joint between adjacent roofing materials (10) is hidden by the cover (40), and the cover (5) is hidden.
Since 0) is arranged in a streak shape along the arch line, the appearance can be improved.

Further, a reinforcing material (20) and a roof material (10)
Is fixed to the purlin (2) using the hook bolts (51) and (52), so that the roofing material (10) can obtain a sufficient holding force in the peeling direction. For this reason, it can reliably withstand strong winds such as typhoons.

By the way, the roofing material of the present invention (10) is to use a plate thickness (T) of 1~5mm 6
It is preferable that the lower limit of the plate thickness (T) is 2 mm or more and the upper limit is 4 mm or less. That is, if the sheet thickness (T) is too small, sufficient rigidity cannot be secured as a roof material, and the initial roof shape may not be maintained for a long time, which is not preferable. Conversely, if the plate thickness (T) is too large, it is difficult to form the rising edge (11), that is, to bend the both side edges, and further, to fix the rising edge (11) by bolt penetration work and the like. Is not preferable because it becomes difficult.

Further, the roof material (10) has a sheet width (W) of 0.1 mm.
It is necessary to use one having a width of 5 to 2.0 m, and preferably one having a lower limit of the plate width (W) of 0.8 m or more and an upper limit of 1.8 m or less. That is, if the width (W) is too small, the seam interval of the roof material becomes short at the time of roof material construction, and there is a possibility that the lighting efficiency and the aesthetic appearance may be reduced, and the mounting pitch may also be shortened. It is not preferable because the workability may be reduced. Conversely, if the sheet width (W) is too large, sufficient rigidity cannot be secured as a roof material, and the initial roof shape cannot be maintained for a long period of time, or the roof material may be damaged, which is not preferable.

The roofing material (10) has a rising edge (1).
1) The height (H) of 10 to 50 mm must be used.
It is necessary to use a material having a lower limit of the height (H) of 20 mm or more and an upper limit of 40 mm or less.
That is, if the height (H) is too low, it may be difficult to connect the roofing materials or fix the roofing material to the purlin, which is not preferable. On the other hand, if the height is too high, the rigidity becomes too high, and it becomes difficult to form the roofing material itself into an arch shape or the like according to the roof shape, or the rising edge (11) rises from the roof surface after construction. It is not preferable because it has an odd shape that protrudes greatly, and the aesthetic appearance may be impaired.

The thickness (T), the width (W) and the height of the rising edge (H) of the roofing material (10) described above are determined.
The same applies to the specific range in the following second embodiment.

2) The height of the hook (7) is formed corresponding to the height of the rising edge (11) of the roofing material (10) made of PC resin.
4), the upper end of the roofing material rising edge (11) can be engaged. At the center of the rising piece (72) and at the center of the mounting piece (73), mounting holes (72) are provided.
a) (73a) is formed. For reference, the length (L) of the presser fitting (70) is about 50 mm.

Then, as shown in FIG.
0) is disposed on the purlin (2) so that its length direction is orthogonal to the purlin length direction, and in this state, a tapping screw (75) inserted into the mounting hole (73a) has a purlin ( It is fixed by being fastened in 2).

The rising piece (72) of the presser fitting (70)
The roofing material (10) is arranged on both sides of the roofing material via a packing (130), and the upper edge of the rising edge (11) of the roofing material (10) is engaged with the hook (74) of the presser fitting (70). The roof material (10) is fixed to the purlin (2) by being pressed downward.

Further, a cover (140) is arranged so as to cover the presser fitting (70) and the roof material rising edge (11) on both sides thereof, and the cover (140) and the roof material rising edge (1).
1) Nut (77) on bolt (76) passing through mounting hole (72a) of packing (30) and presser fitting (70)
Are fastened to fix the cover (140).

Other configurations are the same as those of the first embodiment.

In the roof made of PC resin of the second embodiment, too, the roof materials (10) are connected to each other and the main house (10) is formed by using the rising edges (11) formed on both sides of the roof material (10). 2) Because it is intended to be fixed to, it can be installed without assembling members that hinder lighting, such as rafters and fixed frames,
A high lighting efficiency can be obtained. Further, since the work of assembling the rafters and the fixed frame is not required and the roof weight is reduced, it is possible to improve the working efficiency and reduce the cost.

Further, according to the second embodiment, the connection of the roofing materials (10) and the fixing of the roofing material (10) to the purlin (2) are simultaneously performed by the presser fittings (70). Therefore, cost reduction and improvement in workability can be further achieved by reducing the number of members.

In each of the above embodiments, packing is used as a waterproofing material between roofing materials. However, the present invention is not limited to this, and a sealing agent or the like may be used. However, in consideration of workability, durability, and the like, it is preferable to use packing as in the above embodiment.

In the above embodiment, the case where the present invention is applied to an arched roof has been described.
The present invention can be applied not only to arched roofs but also to single-flow and double-flow roofs.

The length of the roofing material is not particularly limited, and may be set to any length. Further, a relatively short roof material may be connected in the length direction (curved direction) for construction.

[0044]

As described above, according to the roof made of PC resin of the present invention, the connection between the roof materials and the purlin are made by using the rising edges formed along both side edges of the roof material made of PC resin.
