がきわめて困難である。 A wide range of synthetic resin sheets are needed for ground stabilization, drainage, and protection at civil engineering construction sites, for embedding garbage in landfills, and for use in tents for forming domes. for example,
Generally, a large synthetic resin sheet of about 3,000 m 2 to 10,000 m 2 is required for ground stabilization at a housing development construction site, and in this case, a synthetic resin sheet of 500 to 1,000 m 2 is required.
A method of joining several synthetic resin sheets of about 3,000 m 2 to each other by melting them with hot air at a construction site.
For sites with a size up to a certain extent, a method is used in which a synthetic resin sheet of a considerable size, pre-produced in a factory, is laid on site. However, these conventional methods have various deficiencies, and their solution is strongly desired. For example, in the case of the former, the joining work is time-consuming and the joint strength of the joint is weak, so that the function of stabilizing the ground cannot be fully performed. Moreover, in the case of the latter, it requires a lot of manpower and a considerable amount of time to spread it, and therefore it is extremely difficult to construct it on-site.

のである。 One of the two long sides of a rectangular or long synthetic resin sheet is welded with a male claw member that can be welded and has a concave strip across the entire width of its edge, and the other long side is welded. The wing part is formed by welding a weldable female claw member having grooves over the entire width of the long side of the synthetic resin sheet on the inner side of the synthetic resin sheet, which is slightly smaller than the edge of the sheet. Several composite rectangular or long synthetic resin sheets are connected to each other by interlocking the male claws of one synthetic resin sheet with the female claws of another synthetic resin sheet, and the connection This section relates to a vast sheet made of synthetic resin, characterized in that it is covered with the wing section.

等によつて行われる。 That is, the present invention provides an interconnecting function to synthetic resin sheets of a width and length within a range that can be easily handled, transported in a factory, and spread out at a construction site, and by connecting them together to create a large area. It is constructed from a synthetic resin sheet. Since the connection of the present invention is performed only by the extremely simple operation of engaging the convex part of the male claw member with the recessed part of the female claw member, the joining work, especially the joining work at a construction site, is extremely easy. Furthermore, the connection strength of the joints is extremely high. With the wing part covering the connecting part,
It is bonded to the synthetic resin sheet surface, which reinforces the connecting portion and complements the water-stopping effect of the connecting portion. The wings are joined to the surface of the synthetic resin sheet using an adhesive tape, an adhesive, a welder, or the like.

The above-mentioned zipper joining form exhibits the effect shown in FIG. 2. That is, the wing portion 6 hangs over the connecting portion formed by the engagement of the convex strip 4 of the male claw portion 5 of each of the two elongated synthetic resin sheets 1 with the concave strip 2 of the female claw portion 3, The connecting part is covered by part 6,
This protects the joint.

あつてもよい。 The large sheet made of synthetic resin of the present invention connects a plurality of sheets made of synthetic resin of an appropriate width using zippers that are connected by interlocking convex and concave stripes, and the connecting portions are made of the same material. Since the zipper is covered with wings made of a part of the resin sheet, it is possible to obtain excellent bonding strength with an extremely simple joining process, and the performance of the zipper itself and the covering of the connecting parts by the wings Due to the synergistic effect, the closeness is extremely excellent. Because it has such ease of bonding, excellent bonding strength, and excellent tightness of the connecting portions, it is extremely suitable as a vast sheet for use in large-scale civil engineering works sites under severe usage conditions. It is necessary that the protrusions on the male claw member and the grooves on the female claw member of the zipper used in the present invention have the same shape, and that the protrusions are in close contact with the inner surface of the groove. In addition to the circular shape shown in FIGS. 1 and 2, the shape may be a rectangular shape as shown in FIG. 3, or it may have two or more protrusions or grooves.
