Abstract

PURPOSE:To obtain a light-weight, soft filmy material easily by a simplified method in which a reinforcing material containing the same rubber polymer as the rubber of a rubberized fabric filmy material is integrally combined with the side of a spongy sheet 7. CONSTITUTION:A rubber reinforcing material containing the same rubber polymer as the rubber of the outer surface of a rubberized fabric filmy material 4 is integrally combined with one side of a spongy sheet 7 by allowing the rubber reinforcing material to permeate into the sheet 7 slightly with a small thickness of the rubber reinforcing material remaining on the outside. The sheet 7 is bonded to the filmy material 4 through an adhesive 9 at the rubber face. The reinforcing material can thus be produced separately in advance and can also be attached in any form and at any portion.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The structure of an undulating weir made of a flexible membrane material such as rubber-coated cloth is shown in Fig. 6 (hereinafter, the membrane material will be explained using rubber-coated cloth). The undulating weir made of canvas uses a hollow body made of rubberized fabric membrane material (4) shown in Figure 7 below, and when damming up water, air or water (2) is inserted into the hollow part. When pouring water, the air and water in the hollow area are removed and the tube is contracted and laid down.
(See No. 2371).

In Fig. 6, (1) is the flow of a river, etc., (6) is the fixing fitting, and (15) is the floor of the river, etc.

The structure of the rubberized cloth membrane material is shown in Figure 7, and it is made by covering and integrating a nylon or polyester fabric (6) with rubber (5), and the fabrics are laminated according to the required strength. The numbers will be adjusted.

(Problems to be Solved by the Invention) However, in conventional undulating weirs, the membrane material is susceptible to natural or artificial damage. For example, there are penetration wounds caused by driftwood, knife wounds caused by mischief, etc. This is because the material constituting the membrane material is soft and lacks strength.

In view of the above, the present invention has been developed to solve these problems. The present invention will be described in detail below with reference to the illustrative drawings.

(Means for Solving the Problems) That is, the present invention is to form a metal sponge-like material, for example, foamed metal, into a sheet shape as shown in FIG. Used as a reinforcing member to prevent damage.

At this time, the metal sponge-like sheet (7) shall be provided as follows. As shown in FIG. 2, at least one side of the metallic sponge-like sheet (7) is coated with rubber that is the same as or common to the outer surface rubber of the rubberized cloth membrane material (4) that is the covering. A rubber that is the same as the outer surface rubber and contains some rubber polymer is left in some thickness outside, and some of it is allowed to penetrate into the sponge-like sheet or penetrate into the entirety as a reinforcing member. integrated,
The rubber surface thereof is fixed to the covering rubberized cloth membrane material (4) via an adhesive (9). Here, the reason why the intruding rubber is made to be the same as or homogeneous with the outer surface rubber is to take adhesive properties into consideration.

Of course, as shown in FIG. 6, the sponge-like sheet may be protected from the outside by infiltrating the above rubber or another rubber or plastic from the other side. Also,
The way in which the rubber penetrates does not have to be so much that it completely fills the inside of the sponge-like sheet as shown in Figures 2 (al) and 3. In this case, it is light in weight and can be used as a reinforcing member. It has the effect of making you more flexible.

Furthermore, as shown in FIG. 4, rubber or plastic may be infiltrated so as to almost completely fill the inside of the sponge-like sheet. In this case, it is possible to obtain a reinforcing member that is less flexible than those shown in FIGS. 2 (aJ and 3) but is stronger.

Such a reinforcing member may be provided on the entire surface or a part of the covering rubber-coated membrane material, and the reinforcing member may cover a wide area with one piece, or it may be a tile as shown in Fig. 5. It may be divided into parts and covered.

(Function) In the present invention, the reinforcing member prevents natural and artificial damage such as driftwood scratches and knife scratches.

(Effect of the invention) The present invention as described above has the following effects.

(b) Manufacturing and construction methods are easy. That is, ■Reinforcement members can be made separately in advance.

■It may be installed before or after the rubberized cloth membrane material is laminated to the envelope and molded. If it is installed later, the molding can be done as usual, or it can be done after construction.

■Reinforcement members can be attached to any shape and any part,
It will be done.

(01 It's a shame. In other words, ■ The inside of the sponge body can be made hollow as shown in Fig. 2(a) and Fig. 3.

(c) Flexible. That is, (1) It is flexible because it is a sponge-like material. Separate installation is also possible.

) is strong. In other words, ■ Textile materials have directional strength, but since it is a reinforcing member without directional strength, it is equally strong in any direction even if you insert a knife into it.

■Since it is lightweight, it can be made thicker.

■The inside of the sponge-like body can be filled with rubber or plastic to make it stronger.

(E) Easy to repair. That is, (1) since it is later provided on the surface of the rubberized cloth membrane covering the main body, it is not essentially an integral part, and the reinforcing member can be easily replaced.

■Even if the rubber-coated membrane covering is damaged, it can be repaired as before by removing the reinforcing member. Further, it is easy to attach the reinforcing member from above.

In the description of the present invention, the membrane material used as the envelope was explained using rubber-covered cloth, but it is not limited to rubber, and may of course be made of plastic.

Claims (1)

[Scope of Claims] (1) An envelope made of a flexible membrane material such as rubberized cloth is attached to at least the floor of a river in a direction that crosses the flow of the river, etc., and air or water is injected into the interior of the envelope. In an undulating weir that can be made to expand and stand up, or to be deflated by removing air or water from the inside of the cover, a flexible sheet of metal sponge is covered from one side of the molded sheet. Rubber or plastic that is the same as or of the same quality as the outer surface rubber or plastic of the membrane material is infiltrated, and some thickness is left on the outside to be integrated as a reinforcing member to prevent damage, and the rubber or plastic left on the outside is 1. An undulating weir made of a flexible membrane material, characterized in that the surface is attached to the entire outer surface or a partial area of the outer surface of the covering flexible membrane material via an adhesive. (2) Claim (1) in which the reinforcing member is one in which the same or different rubber or plastic is infiltrated from the other side surface to completely fill the inside of the sponge body.
