Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art Polycarbonate (hereinafter referred to as "PC") resin has excellent weather resistance, impact resistance, and transparency, so that it can be used as a roofing material for daylighting in pools, warehouses, gymnasiums,
It is widely used from large buildings such as station buildings to small buildings such as bus stops, bicycle storages and carports.

Conventionally, as a polycarbonate resin plate used as a roofing material, a flat plate-shaped plate is mainly used. When an arch-shaped roof as shown in FIG. 9 is formed using such a flat roof material, a rafter (3) is placed on the purlin (2) assembled on the basic steel frame (1). It is constructed by finely assembling to form a grid, and making the roof as a whole an arch shape, and further by assembling a fixed frame made of aluminum or the like on each grid, and inserting a flat roof material (4) into this frame. It is customary.

The roof shape is not limited to the arch shape, and even if the roof shape is a single-flow structure or a double-flow structure, it is basically used when the flat PC resin roof material (4) is used. Will be constructed by the same method as above.

[0005]

However, in the above-mentioned conventional PC resin roof, the rafter (3) must be incorporated on the purlin (2), and the fixing frame must be fitted.
There is a problem that these occupy a considerable area on the roof and the lighting rate is reduced. Further, since a lot of labor is required for the work of assembling the rafters (3) and the work of fitting the fixing frame, there is a problem that the work efficiency is lowered and the cost is increased. Furthermore, since the weight of the entire roof will increase due to the rafters (3) and the fixed frame, it is necessary to construct a solid foundation steel frame (1) that can withstand the weight of the roof. Occurs and the cost increases.

The present invention solves the above-mentioned problems of the prior art, has a high lighting rate, and can be installed efficiently at low cost.
The purpose is to provide a resin roof.

[0007]

In order to achieve the above object, a polycarbonate resin roof of the present invention comprises a plurality of polycarbonate resin roof members provided with rising edges along both side edges. On the roof of a building, a plurality of the roof materials are arranged side by side along the length direction of the roof in a state where the length direction of the roof material is orthogonal to the length direction of the roof. The gist is that the edges are connected to each other and the rising edges of the roof material are fixed to the corresponding purlins.

The PC resin roof of the present invention utilizes the rising edges formed along both side edges of the PC resin roof material to connect the roof materials and fix them to the purlin. Roof construction can be performed without assembling members such as rafters and fixed frames that interfere with daylighting. Therefore, it is possible to obtain a high light collection rate without impairing the transparency of the PC resin.

Further, since the troublesome 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, the roof weight can be reduced, so that the labor for the foundation work is also reduced. Therefore, the work efficiency can be further improved and the cost can be further reduced.

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

Further, according to the present invention, since the roofing material has a simple shape in which rising edges are provided on both side edges of the PC resin plate, the bending can be easily performed. Therefore, when the roof shape is arched, for example, a PC
The radius of curvature can be reduced compared to resin-made plates,
It can be applied to a wide range of purposes from large buildings to small buildings.

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

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

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

As shown in both figures, the roof portion of this building is formed in an arch shape and is constructed by using a roof 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 so that the rising edge (11) is formed. In addition to being formed, the length direction is curved and formed in an arch shape following the roof shape.

A plurality of such roofing materials (10) are arranged side by side along the length direction of the purlin (2) as shown in FIGS. Corresponding rising edges (11) (11) are connected to each other as described below, and the rising edges (11) of each roofing material (10) are fixed to the purlin (2) by suitable means described below. Then, the building roof is constructed.

The roof of this embodiment will be described in detail below.

FIG. 3 is a sectional view taken along line III-III in FIG. 2, and FIG. 4 is a sectional view taken along line IV-IV in FIG. As shown in both figures, a plurality of purlins (2) made of lip channel steel are assembled in an arch shape on a foundation steel frame (1) of a building, and a roof shape is imitated on the purlins (2). A reinforcing member (20) made of rectangular steel curved in an arch shape is arranged along a direction orthogonal to the length direction of the purlin (2). This reinforcement (2
0) is a state where the hook bolts (51) (52) are vertically penetrated and the hook portions of the hook bolts (51) (52) are engaged with the lip pieces and the lower surface region of the purlin (2), On the screw shaft part above the hook bolts (51) (52),

0) and the rising edge (11) of the other roofing material (10)
Then, the bolt (53) is penetrated, and the nut (63) is fastened to the screw shaft portion of the bolt (53) from the opposite side. Thus, the corresponding rising edges (11) sandwich the reinforcing material (20), and the roofing material (10) has the reinforcing material (2).
It is fixed to the purlin (2) via 0). The packing (30) is continuously arranged along the rising edge portion (11) of the roof material (10).

The cover (40) for covering the periphery of the reinforcing material (20) is made of U-shaped steel, and is the same as the roof material (10) and the reinforcing material (20) and has a roof shape in the longitudinal direction. It is curved and formed in the shape of an arch. Reinforcing material (20) so that this cover (40) accommodates the reinforcing material (20) and the roof material rising edge (11) in the U-shaped groove.
The hook shafts of the hook bolts (51) and (52) are arranged on the cover (40) so as to penetrate from the lower side. 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) through the reinforcing material (20) by pressing the (64) onto the upper surface of the cover (40).

In this PC resin roof construction procedure, first, the reinforcing material (20) is fixed on the purlin (2). Subsequently, the reinforcing material (20) is sandwiched by the packing (30), and the roof material (10) is attached to the cover (4).
0) is fixed.

As described above, according to the PC resin roof of this embodiment, the roof material (10) is formed by utilizing the rising edges (11) provided on both side edges of the PC resin roof material (10). Since they are intended to be connected to each other and fixed to the purlin (2), roof construction can be performed without assembling a large number of members such as rafters and fixing frames that obstruct the lighting as in the conventional case in the purlin. Therefore, P
A high lighting rate can be obtained without impairing the transparency of the C resin. In addition, since roofing work does not require the troublesome work of assembling rafters and fixed frames, work efficiency can be improved and costs can be reduced, and the roof weight can be reduced. Labor can be reduced, and work efficiency can be further improved and cost can be reduced.

Further, since the roof material (10) has a simple shape in which both side edges of the PC resin plate are simply bent, the arch-shaped roof material (10) is formed as in this embodiment. In this case, for example, it can be bent more easily than a PC resin folding plate. Therefore, for example, the radius of curvature can be reduced, and the invention can be applied to a wide range of applications from large buildings to small buildings. Roof material (10)
Since both edges of the roof are bent, the roof material itself can have sufficient strength, for example, the initial roof shape can be maintained for a long time, and damage to the roof 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 enhanced, and defects such as deformation of the roof shape and damage to the roof material can be more reliably prevented.

In the present embodiment, the packing (30) is interposed between the adjacent roofing materials (10), and

Since it is covered by, it is possible to ensure waterproofing between the adjacent roofing materials (10), and it is possible to reliably prevent problems such as rain leakage.

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

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

By the way, the roof material (10) of the present invention has a plate thickness (T) of 1 to 5 mm as shown in FIG. 6, preferably a lower limit of the plate thickness (T) is 2 mm or more and an upper limit. It is better to use a tape having a diameter of 4 mm or less. That is, this plate thickness (T)
If it is too small, sufficient rigidity as a roofing material cannot be secured, and the initial roof shape may not be maintained for a long time, which is not preferable. On the contrary, if the plate thickness (T) is too large, it becomes difficult to form the rising edge portion (11), that is, to bend both side edge portions, and further, bolt penetration work etc. at the time of fixing the rising edge portion (11). Is difficult to do, which is not preferable.

Further, the roof material (10) has a board width (W) of 0.
It is preferable to use a sheet having a width of 5 to 2.0 m, preferably a sheet width (W) having a lower limit value of 0.8 m or more and an upper limit value of 1.8 m or less. That is, if this width (W) is too small, the seam spacing of the roof material during the construction of the roof material may be shortened, which may reduce the lighting rate and the appearance, and the mounting pitch may be shortened. It is not preferable because workability may be reduced. On the other hand, if the plate width (W) is too large, sufficient rigidity cannot be secured as a roof material, the initial roof shape cannot be maintained for a long time, and the roof material may be damaged, which is not preferable.

The roof material (10) has a rising edge (1
The height (H) of 1) is 10 to 50 mm, preferably the lower limit of the height (H) is 20 mm or more and the upper limit thereof is 40 mm or less. That is, this height (H)
If it is too low, it may be difficult to connect the roof materials or fix the roof material to the purlin, which is not preferable. On the other hand, if it is too high, the rigidity becomes too high, making it difficult to form the roof material itself into an arch shape or the like according to the roof shape, or after the construction, the rising edge portion (11) is separated from the roof surface. It is not preferable because it may have a strangely protruding shape, which may impair the aesthetic appearance.

The preferred ranges of the plate thickness (T), the plate width (W), and the rising edge height (H) in the roofing material (10) described above are the same in the following second embodiment. Can be said.

Are fastened to fix the cover (140).

The other structure is the same as that of the first embodiment.

Also in the PC resin roof of the second embodiment, the rising edge portions (11) formed on both sides of the roof material (10) are used to connect the roof materials (10) with each other and to the purlin ( Since it is intended to be fixed to 2), it can be installed without assembling members such as rafters and fixing frames that interfere with daylighting.
A high lighting rate can be obtained. Further, since the work of assembling the rafters and the fixed frame is not required and the weight of the roof is reduced, the work efficiency can be improved and the cost can be reduced.

Moreover, according to the second embodiment, the roof metal fittings (70) are used to connect the roofing materials (10) to each other and fix the roofing materials (10) to the purlin (2) at the same time. Therefore, by reducing the number of members, it is possible to further reduce costs and improve workability.

In each of the above embodiments, the packing is used as the waterproofing material between the roof materials, but the present invention is not limited to this, and a sealing agent or the like may be used. However, considering workability and durability, it is preferable to use packing as in the above-described 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 an arch-shaped roof but also to a roof made of one-way or double-flow.

The length of the roof material is not particularly limited, and may be set to any length. Furthermore, roofing materials having a relatively short size may be joined together in the length direction (curving direction) for construction.
