[Prior art]

 Conventionally, this type of plastic roof has a plurality of pillars to which beams are respectively attached, a plurality of support members are laid on these beams, and a plurality of transparent plastics are mounted on these support members. It is known that roofing boards such as boards are stretched over.

However, in the above-mentioned conventional roof, since the roof plate is mounted on the beam via the support member, the weight of the roof is increased by the amount necessary for the support member and the roof is supported. For this reason, greater support strength is required for the beams and columns, but since the receiving material is intervening, the transmitted light is blocked by it, making it feel dark, and the roof looks thick, so the appearance is neat. It wasn't.

Further, since a gutter of aluminum or vinyl chloride resin is separately provided on the outer edge portion of the roof plate, it takes time to assemble, the cost is high, and the roof plate and the gutter of the roof plate are long-term use. There was a risk of water leaking from the joints, and there was also the problem of corrosion of the gutter bracket used to connect the roof panel to the gutter.

【Example】

 Next, the present invention will be described in detail. FIG. 1 shows an example of a plastic roof unit 1 of the present invention. The plastic roof unit 1 is roughly composed of a roof portion 2, a gutter portion 4 and a connecting portion 3 connecting them. The roof portion 2 has a substantially semi-cylindrical shape as a whole, the cross-sectional shape in the lateral direction thereof is an arc shape, and the cross-sectional shape in the longitudinal direction thereof is trapezoidal. Is inclined to form a water gradient. The connecting portion 3 is connected to the roof portion 2 below the water gradient of the roof portion 2 and surrounds the entire circumference of the roof portion 2. The connecting portion 3 has a perforated hole 5 about every 400 mm, but the interval between the perforated holes 5 can be appropriately selected. Further, on the underwater side adjacent to the connecting portion 3, there is a trough portion 4 having a U-shaped cross section and having a groove portion in the longitudinal direction. The gutter part 4 surrounds the entire circumference of the roof part 2, and a drain hole 6 is provided on the most water side. The size, number and position of the drain holes 6 are arbitrary.

The plastic roof unit 1 has a roof part 2, a connecting part 3 and a trough part 4 integrally formed by a vacuum forming method using one large plastic plate. Further, the size of one plastic roof unit 1 is large, such as about 4400 mm in length, 2200 mm in width, and 450 mm in height.

The material of the plastic roof unit 1 is preferably a resin plate having a thickness of 3 to 10 mm such as methacrylic resin or polycarbonate resin, but it is suitable for the vacuum forming method, and the product after molding has an appropriate strength. It is not particularly limited as long as it has it. In addition, various colors such as transparent, colored transparent, and opaque are applied according to the application.

Next, the plastic roof 13 of the present invention will be described with reference to FIGS. 4 to 6. In this plastic roof 13, a plurality of the plastic roof units 1 are arranged so that they are adjacent to each other on the long side, and are attached to the frame 7. The skeleton 7 is roughly composed of a pillar 8, a beam member 9 and a connecting member 10. Generally, the pillar 8 is erected at a predetermined interval on the ground surface, and the beam member 9 is on the pillar 8. It is joined.

The columns 8 are made of steel pipe, and two columns are used for one plastic roof unit 1. Further, the beam member 9 is a rectangular frame body, and a single beam 11 is provided so as to span the frame body so that the frame body is divided into two. The beam member 9 and the beam 11 are fastened to each other at right angles so that they do not overlap vertically. Such beam members 9 are connected by the number of the plastic roof units 1 so that the beams 11 are parallel to each other. Further, the beam member 9 and the beam 11 are fastened by an appropriate fastening means such as welding or a combination of bolts and nuts. The same applies to the following fastening and connection.

A connecting member 10 is used for the connection. The connecting member 10 is made of channel steel having a length of 240 mm and a width of 180 mm, and is connected to the four corners of the beam member 9 in a direction perpendicular to the beam 11. Further, the connecting member 10 and the connecting member 10 are joined together via a prismatic steel pipe. The columns 8 are connected to the center of the beam 11 as a pair, and are connected to the beam 11 so as to form a right angle with the beam 11. Further, a slight gap is formed between the columns 8 of this set.

At this time, steel pipes are preferably used for the columns 8, channel steels are used for the beam members 9, and H-shaped steels are used for the beams 11, respectively. These types, numbers, lengths, and thicknesses are preferably used. , Strength, position, etc. are arbitrary and can be appropriately selected according to the purpose. For example, if a ladder member is used as the beam member 9, it is not necessary to use the connecting member 10 for connecting the beam members 9 to each other.

The plastic roof unit 1 is arranged on the skeleton 7, and is fastened to the beam member 9 through a blind hole 5 provided in the connecting portion 3 of the plastic roof unit 1. Further, drainage holes 6 are provided in the gutter portion 4 in the vicinity of the beam members 9, and the drainage holes 6 are used as drainage ports, and a drainage pipe 12 is connected to the tip of the drainage port. The drainage pipe 12 reaches the support 8 along the beam member 9, and is installed between the support 8 and the support 8 along the support 8 and extends to near the ground surface. The number of drainage ports is arbitrary as long as there is one or more drainage ports per plastic roof unit 1.

Further, the plastic roof unit 1 of the present invention also has, as a second example, a shape as shown in FIGS. 7 and 8. In the example shown in FIG. 7, the two corners on the short side are more angular than in the first example, and the area of the corner of the connecting portion 3 is larger by that amount. Further, in the case shown in FIG. 8, all four corners are angular. However, except for the shape of the corner, such as the material of the plastic roof unit 1, it is the same as the first example.

Next, a plastic roof 13 using the plastic roof unit 1 having the shape shown in FIG. 7 will be described with reference to FIGS. 9 to 11. Similar to the first example, this plastic roof 13 is also made up of a plurality of plastic roof units 1 adjacent to each other and mounted on the skeleton 7.

The difference from the first example is that the combination of the plastic roof unit 1 and the skeleton 7 are assembled in a cantilevered supporting state. In other words, as shown in FIG. 9, the combination of the plastic roof units 1 is such that the short sides having angular corners are adjacent to each other and the sides are long.

Further, in this example, as shown in FIG. 11, a cantilever-supported skeleton 7 is used in which pillars 8 standing upright at predetermined intervals are joined near one end of a beam member 9. It has been done. In addition, other conditions, for example, the method of fastening the frame 7 and the plastic roof unit 1, the installation of the drainage port, and the drainage pipe 12 are the same as those in the first example.

As described above, the plastic roof unit 1 of the present invention can be freely combined, and the plastic roof 13 of various shapes and sizes can be formed. Therefore, not only the examples given here but also the purpose and the application can be used. Then, the number of columns 8, the installation positions of the columns 8 and the beam members 9, and the specific conditions such as the form of the beam members 9 can be appropriately changed.

For example, also in the first example, a cantilevered support state can be obtained as in the second example. In addition, as shown in FIG. 12, they may be adjacent to each other on the short side. Furthermore, a large plastic roof 13 can be created by connecting both the long side and the short side, or conversely, it can be used alone in a place where the installation space is small.

Also in the second example, similarly to the first example, the both-end support state can be obtained. Further, the long sides may be adjacent to each other. However, in this case, it is preferable to use the plastic roof unit 1 in which the two long side corners are angular. Further, as shown in FIG. 13, when three or more plastic roof units 1 are connected in succession, all four corners as shown in FIG. 8 except for the plastic roof units 1 arranged at both ends are provided. It is preferable to use an angular product.

Further, the shape of the plastic roof unit 1 can be any shape other than the shapes shown in FIGS. 1 to 3, 7 and 8. For example, the shape of the trough portion 4 may not be a U-shaped cross section but may be a semicircular cross section. Furthermore, the shape viewed from the roof portion 2 is not limited to a rectangle, but may be a hexagon or the like.

The plastic roof 13 of the present invention having such a structure is composed of the roof portion 2 and the gutter portion 4 surrounding the entire circumference of the roof portion 2, and the roof portion 2 and the gutter portion 4 are one sheet. Since the plastic roof unit 1 formed by integral molding of the plastic plate is attached to the beam member 9 in the vicinity of the gutter part 4, a metal support material for mounting the roof plate is not required, and a gutter support metal fitting. Since it is not necessary, it is possible to reduce the weight of the roof, increase the lighting area, increase the transmitted light and feel bright, and it is possible to finish it with a neat and aesthetically pleasing design. It is possible to eliminate the space where dust adheres, and to prevent the possibility of water leakage. In addition, it requires less on-site construction, and since the metal part is completely covered by the plastic part, the effect of rain and wind on the metal part is small, the coating lasts a long time, and the risk of corrosion is also small. . Moreover, since the plastic part is entirely heat-processed, the distortion is small, the quality is good, and the plastic roof unit 1 of various sizes, colors, and shapes can be manufactured. The cost can be reduced. Furthermore, by combining the plastic roof units 1, it is possible to obtain plastic roofs 13 of various shapes and sizes, so that it is possible to accurately meet a wide range of consumer needs.
