Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of mounting a synthetic resin roofing material comprising a plurality of synthetic resin roofing materials, and a connecting fixture for the same.

[0002]

2. Description of the Related Art Transparent synthetic resins, such as polycarbonate resins, are excellent in weather resistance, impact resistance, and transparency.
From large buildings such as station buildings, bus stops, communication passages between buildings,
It is widely used in small buildings such as bicycle sheds and carports.

Conventionally, a roofing material made of synthetic resin used as a roofing material is mainly of a flat plate shape. And as a mounting structure of such a flat roof material,
When forming an arched roof, rafters are finely assembled on the main house assembled on the base steel frame to form a square, the entire roof is arched, and a metal fixing such as aluminum is placed on each square. In general, a frame is assembled and a flat roof material is fitted into the fixed frame, or a synthetic resin roof material is pressed around the fixed frame by the fixed frame.

[0004] The roof material mounting structure is not limited to the arch shape of the target building, and may be a flat synthetic resin roof material even if the roof 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 structure for mounting a roofing material, in addition to the metal fixing frame as described above, a rafter for assembling the fixing frame is added, so that the roof of the daylighting roof is provided. There is a problem that the lighting efficiency is reduced as a result of occupying a considerable part, and the entire roof is heavier due to the metal fixing frame and rafters, and the base steel frame only needs to be strong enough to withstand this. However, there has been a problem that much labor is required for the work of assembling the rafters, the work of attaching the fixed frame, and the like, which lowers the work efficiency and increases the construction cost of the lighting roof. In addition, it is necessary to fill the gap between the fixed frame and the roofing material with a sealing material in order to prevent water leakage, and the installation of the roofing material itself has been complicated.

In order to solve the above-mentioned problems, the present inventors previously bent a transparent synthetic resin plate such as a flat polycarbonate as a roof material by bending and forming the same along both side edges. The following proposals were made using a bent-formed plate having a rising edge portion and a mounting structure for a synthetic resin roofing material.

First, a first proposal is disclosed in Japanese Patent Laid-Open No. 9-1442.
24 publication, on the main roof of the building,
A plurality of the bent formed plates are arranged in parallel along the length direction of the purlin in a state where the length direction thereof is orthogonal to the length direction of the purlin, and the corresponding rising of the adjacent bent formed plates is arranged. In this structure, the edges are connected to each other with a fixing member such as a bolt and a nut via a reinforcing member or a holding member mounted so as to be orthogonal to the purlin and along the same. Note that the waterproof cover of the connecting portion is attached at the same time as the connecting operation.

[0008] In the first proposal, since no rafters or fixed frames are used, the lighting efficiency is improved as compared with the related art.
Although there is an advantage that the material cost can be considerably reduced, however, in addition to connecting the rising edge of the bent-formed plate with a fixing member such as a bolt nut via the reinforcing material or the holding metal, a hook bolt or a bolt is further required. Since the structure is such that it is attached to the main house in an exposed state, it is troublesome, the appearance is poor, and it cannot be said that the above effects can be sufficiently obtained in terms of lighting and working efficiency.

A second proposal is disclosed in Japanese Patent Laid-Open No. 10-121.
665, which has a length equal to the width of the purlin as a fixing tool for connecting the bent-formed plate on the main roof of the building, and fixes the vertical connecting wall and the left and right lower ends. A metal member having a U-shaped cross section composed of a wing and upper and lower connecting wings is fixed using a fixing hole of a fixed wing so that the connecting wall is orthogonal to the length direction of the purlin, and then the bending is performed. A plurality of formed plates are arranged in parallel along the length of the purlin in a state where the length direction is orthogonal to the length direction of the purlin,
The corresponding rising edge of the adjacent bent-formed plate,
In this structure, the connecting wall is disposed so as to sandwich the connecting wall from both sides, and then a connecting fixture is used which is connected by bending the connecting wing downward.

[0010] In the second proposal, the lighting efficiency can be improved and the material cost can be reduced as compared with the conventional one in the same way as in the first proposal. On both sides of the connecting wall of the connecting fixture, a rising edge of the bent formed plate is arranged so as to be in contact with the connecting wall, and the connecting wing is fixed by bending the connecting wing downward. It is not necessary to connect the rising edge of the fixing member with a fixing member such as a bolt and a nut, and a member such as a screw is used only for fixing the connecting fixture to the purlin. Easy. In addition, the waterproof cover has an advantage that it can be mounted later after the bending-formed plate is completely fixed.

However, according to the second proposal,
When fixing the fixed wing at the lower end of the connecting fixture to the purlin with a fixing member, the connecting wings at the upper left and right obstruct tools such as a driver to be used, and it is difficult to fix the fixing tool at an accurate position. There is a new problem. As a method of solving this, a work hole for directing a tool perpendicular to the fixing hole is provided directly above the fixing hole of the connecting wing, and the fixing work is performed through the tool through the working hole. Although it is conceivable, in practice, a work hole large enough to match the shape and size of the tool is required, and this work hole reduces the rigidity of the connecting wing, and it is necessary to securely fix the bent plate. become unable. In addition, an extra step of drilling a working hole is required, which is not preferable in terms of function and cost as a fixture.

Under the above-mentioned conventional technical background, the present invention aims at improving the technology according to the second proposal above, simplifying the construction work, increasing the lighting efficiency and reducing the cost. Accordingly, it is an object of the present invention to provide a method of attaching a synthetic resin roofing material having an improved appearance quality and a connecting fixture thereof.

[0021]

Embodiments of the present invention will be described below with reference to the drawings showing examples.

FIG. 1 is a perspective view showing a building having a flat roof structure to which a synthetic resin roofing material is mounted, and shows a building which has been mounted using a mounting method unique to the present invention and a connecting fixture. Things. That is, a synthetic resin roofing material (3) is arranged on a main building (2) serving as a framework of the building (1) so that the extending direction is orthogonal to the main building (2), and the main part (A) is enlarged. As shown in FIG. 2, at the rising edge (4) of the synthetic resin roofing material (3) adjacent to each other in the longitudinal direction of the purlin (2), it is attached by connecting with a connecting fixture (5). Further, a cap material (6) is applied.

As shown in FIG. 3, the synthetic resin roofing material (3) applied in the present invention has rising edges (4) on both side edges of the synthetic resin plate (P) in its cross section. The rising edge (4) is formed by bending the side edge of the flat plate at right angles to the longitudinal direction by, for example, a bending method.

The synthetic resin roofing material (3) preferably has a dimensional specification in the range of thickness (s) 1 to 5 mm and width (w) 0.5 to 2 m. The height (h) of (4) is suitably in the range of 10 to 50 mm.
Here, the thickness (s) is set in the range of 1 to 5 mm by 1
If it is less than 5 mm, the bending of the synthetic resin plate (P) becomes large, and it is necessary to shorten the interval of the purlin (2) to increase the number. If it exceeds 5 mm, not only the weight increases but also the rising edge (4) This is because it becomes difficult to bend. 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. This is because it is a factor that hinders the appearance of the building (1), and if it exceeds 2 m, the weight increases and the construction work becomes difficult. Further, the height (h) of the rising edge (4) is set to 10 to 50 mm. If the height (h) is less than 10 mm, the connection by the connecting fixture (5) described later becomes unreliable. This is because the rising edge portion (4) of the roofing material (3) is buckled and deformed and cannot be used as a roofing material as it is, particularly when the target roof shape is an arch shape.

Next, as shown in FIG. 4, the connecting fixture (5) has an inverted T-shaped cross section composed of a vertical connecting wall (5a) and fixed wings (5b) (5b) extending right and left at the lower end thereof.

The connecting wings (5c) and (5c) are similarly bent as indicated by imaginary lines to hold the rising edges (4) and (4) of the roofing materials (3) and (3) inside. Serve to restrain this.

As the material of the connecting fixture (5), a rustproof metal having excellent bending workability and appropriate rigidity is suitable, for example, stainless steel or the like. Further, as shown in FIG. 5, for example, a stainless steel plate having a thickness in the range of 0.3 to 1.0 mm
It is bent into an L-shaped cross-section and joined at the joint (t) of the two processed pieces obtained to form an integrated body having an inverted T-shaped cross-section. The position of t) is usually a plurality of positions of the connecting wall (5a) below the connecting wing (5c), and the height (H) of the connecting wall (5a) is equal to the height of the roof material (3). The thickness is determined in consideration of the thickness (s), the height (h) of the rising edge portion (4), and the thickness (q) of the packing material (Q) that is generally used. The connecting wing (5c) (5) formed by bending the upper part of 5a)
The total length (C) of c) is set within a range of about 20 to 60 mm, and the bending of each connecting wing (5c) (5
Basically, the work pieces (5 ′) and (5 ′) of two layers are integrally and simultaneously bent for each c), but the present invention is not necessarily limited to this, and each connecting wing (5c) (5c) It is also possible to bend the work pieces (5 ') (5') of two layers in the left and right different directions (not shown) every time.

Further, as shown in FIG. 6, the cap member (6) has an elastic bending portion (6a) and engaging portions (6b) (6b) extending right and left downward and bent inward to the lower end. The cross-section formed by the open leg walls (6c) and (6c) having the shape is formed of a long object made of a substantially inverted U-shaped steel plate. The resilient bending portion (6a) causes the engaging portions (6b) (6
b) always acts so as to reduce the width (v) therebetween, and the engaging portions (6b) (6b) are provided with connecting wings (5c) for restraining the rising edges (4) (4). It engages with the tip of (5c) 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 synthetic resin-coated steel sheet having a thickness of 0.8 mm along the length direction. At this time, the width (v) between the engaging portions (6b) and (6b) is approximately 5 mm, and the shape of the engaging portions (6b) and (6b) is as shown in FIG.
In addition to the hook shape as shown in FIG. 7, for example, a wound shape as shown in FIG. 7 is selected, and the folded length (m) or (n) is about 2 mm. It is important that the cap member (6) has a shape that does not come off when engaged with the tip of the connecting wing (5c) (5c).
