Description

Straight wall rubber dam body

technical field

The utility model relates to a rubber dam body and belongs to the technical field of rubber dam structures.

Background technique

At present, the bonding method of the straight-wall rubber dam dam bag is mostly to use the vulcanized rubber dam piece to cut off the inner and outer layers of glue and polish the skeleton layer, and then apply glue, sew, glue and vulcanize. Rubber dam bags may have the following quality hazards:

1. When the vulcanization reaches the downstream dam angle, due to the increase of the radian, the overlapping part of the dam head and the dam bag needs to be folded or stacked. During vulcanization, the uneven thickness will cause undervoltage and deviation. When the rubber dam is in operation, the above There is a high possibility of delamination or water leakage;

2. When the vulcanization reaches the corner of the dam, since the vulcanization angle needs to be changed by 90 degrees, the processing is difficult, and the splicing size and the thickness of the process at the corner of the dam are difficult to guarantee, which adds difficulties to the installation of the dam bag.

Contents of the invention

The purpose of this utility model is to solve the shortcomings of the above-mentioned prior art, and provide a straight-wall rubber water tank with uniform force, firm adhesion, prevention of folding of overlapping parts, and guaranteed engineering size, thereby prolonging the service life. Dam body.

The straight-wall rubber dam body of the present utility model includes a dam bag 1 and a dam head 2 connected thereto. fixed;

The skeleton layer 3 is an L-shaped folded sheet whose two sides are matched with the ends of the dam bag 1 and the dam head 2 respectively;

The dam angle 4 is formed by connecting the L-shaped folded sheet 5 and the folded horizontal plate 6 on both sides respectively with the dam bag 1 and the end of the dam head 2, and the two ends of the folded horizontal plate 6 are connected with the dam bag 1 and the dam head 2 respectively. The horizontal folded end 7,8 at the dam corner of the dam is fixed.

Compared with the prior art, the straight-wall rubber dam body of the utility model has the advantages of uniform stress and firm bonding, and basically eliminates the phenomenon of discounting at overlapping parts; , so as to ensure that the two corners of the upstream and downstream dams are flat and uniform, ensure the project size, prolong the service life of the entire dam body, and reduce the maintenance of the dam body operation.

Detailed ways

Below with reference to accompanying drawing, provide the specific embodiment of the present utility model, be used for further explanation to the structure of the present utility model.

Example 1

The straight-walled rubber dam body of this embodiment refers to Figures 1, 3, and 4, and includes a dam bag 1 and a dam head 2 connected thereto. Corner 4 is bonded and fixed, and skeleton layer 3 is an L-shaped folded sheet whose two sides match with the ends of dam bag 1 and dam head 2 respectively. The type folding sheet 5 is connected with the folding horizontal plate 6 to form, and the two ends of the folding horizontal plate 6 are respectively fixed with the horizontal folding ends 7,8 at the dam corners of the dam bag 1 and the dam head 2.

Processing technology: 1. First heat seal the unvulcanized part of the bonding part of the rubber dam bag 1 with the unvulcanized skeleton layer 3; 2. Then heat seal the unvulcanized part of the bonding part of the dam head 2 with the unvulcanized Heat sealing; 3. The dam bag 1 and the dam head 2 are heat-bonded together with the pre-vulcanized dam corner 4 to realize a 90-degree turning angle at the dam corner and overcome the difficulty in processing.

Compared with the prior art, this embodiment has the following positive effects: this embodiment adopts a specific skeleton layer to bond the dam head and the dam bag evenly and flatly, and has the advantages of uniform force and strong adhesion compared with the prior art. It has the advantages of firmness and other advantages, basically eliminating the phenomenon of discounting at the overlapping parts; the corners of the dam are bonded with special-shaped corners to ensure that the corners of the upstream and downstream corners are flat and consistent, ensuring the size of the project and extending the entire dam body The service life of the dam body is reduced, and the maintenance of the dam body operation is reduced.
