Abstract

The anti-displacement easy-to-install embedded steel-edge rubber waterstop and equipment tooling and preparation process are composed of a metal plate and two layers of rubber bodies, and the rubber bodies are bonded to the upper and lower surfaces of the metal plate by extrusion vulcanization; the processing equipment tooling is composed of a laser cutting machine, a cold feed extruder, an extrusion die, a vulcanization device, a cooler and a coiling and packaging machine. Before the metal plate is introduced into the extruder, the laser cutting machine intermittently cuts expansion joints along the length direction at the middle position in the horizontal direction, and bonds the rubber sheet to the upper and lower surfaces of the metal plate by extrusion vulcanization process. During the construction process, the rubber waterstop of the present invention can ensure that the waterstop does not sag, bend, or deflect due to its own gravity and the impact of poured concrete, and it can still maintain a horizontal state without displacement without the need for an external support device, thereby enhancing the anchoring ability of the waterstop, fully exerting the waterproof performance of the waterstop, and reducing the construction time of installing a waterstop support device.

Description

Technical Field

[0001] The invention relates to the technical field of rubber waterstop processing equipment, and in particular to an anti-displacement, easy-to-install, embedded steel-edge rubber waterstop, equipment tooling and a preparation process. Background Art

[0002] Steel edge waterstop is a rubber waterstop with a non-uniform thickness structure in cross section, which is divided into a strong area and a waterproof area, so that each part is evenly and reasonably stressed. Mounting holes are added to the steel plate of the waterstop to connect with the steel bars, which are firmly fixed and not easily displaced, so that each part is evenly and reasonably stressed. Currently, the steel edge waterstops on the market are composed of a rubber body in the middle and steel belts inserted on both sides of the rubber body. The existing steel edge waterstops are prone to displacement during installation because the middle body is a rubber body, and several supporting devices need to be installed. The installation and construction are troublesome. Once displacement occurs, it will cause voids in the concrete, and the waterproof performance of the waterstop cannot be fully exerted, affecting the quality of the tunnel project and endangering driving safety. Summary of the invention

[0003] The invention provides an anti-displacement and easy-to-install embedded steel-edge rubber waterstop, equipment tooling and a preparation process, so as to solve the problems of difficult construction and low structural strength of the steel-edge waterstop in the prior art.

[0004] The technical solution adopted by the present invention to solve its technical problem is:

[0005] The utility model discloses a displacement-proof and easy-to-install embedded steel-edge rubber waterstop, which is composed of a metal plate and two layers of rubber bodies. Expansion joints are intermittently cut into the metal plate along the length direction in the middle position of the horizontal direction, and the upper and lower layers of rubber bodies are bonded to the upper and lower surfaces of the middle part of the metal plate by an extrusion vulcanization process.

[0006] The metal plate is a galvanized steel plate, a copper plate or a stainless steel plate, and one or more expansion joints are cut according to actual needs of the project to meet the expansion performance requirements.

[0007] The equipment and tooling of the above-mentioned anti-displacement and easy-to-install embedded steel-edge rubber waterstop consists of a laser cutting machine, a cold feed extruder, an extrusion die, a vulcanizing device, a cooler and a winding and packaging machine. The laser cutting machine is connected to the cold feed extruder. The cold feed extruder includes an extrusion main unit and an extrusion tube. The outlet of the extrusion tube is connected to the side feed hole of the extrusion die. The extrusion die includes a pressing die block, upper and lower heat dissipation modules and an extrusion module. The water inlet and outlet opened on one side of the pressing die block are connected. A number of heat dissipation water channels are arranged inside the heat dissipation module and the extrusion module. The outlet of the extrusion die is connected to the vulcanizing device. The vulcanizing device includes a microwave vulcanizing box and several hot air vulcanizing boxes. The outlet of the vulcanizing device is connected to the cooler, and the outlet of the cooler is connected to the inlet of the winding and packaging machine.

[0008] Negative pressure suction hoods are respectively arranged above the extrusion die and on the top of the vulcanization device.

[0009] The preparation process of the above-mentioned anti-displacement easy-to-install embedded steel edge rubber waterstop is to bond the rubber body to the upper and lower surfaces of the metal plate through an extrusion vulcanization process to form an integrally penetrating rubber waterstop. The specific process steps are as follows:

[0010] (1) Rubber body processing: weigh the rubber blocks together with the weighed oil and carbon black and send them into the internal mixer to get the semi-finished product. After the rubber sheet is cooled, take a small sample for vulcanization and inspection. After passing the inspection, send it to the cold feed extruder;

[0011] (2) Steel strip processing: clean the surface of the metal sheet, then apply adhesive to the middle of the upper and lower surfaces of the metal sheet, dry it, and then feed it into the laser cutting machine;

[0012] (3) Laser cutting: The laser cutting machine cuts expansion joints intermittently along the length direction in the middle of the metal plate. The expansion joints can be adjusted according to construction requirements.

[0013] (4) Extrusion molding: The galvanized steel sheet is fed into the extrusion die through the pressing feed port by the feeder. At the same time, the cold feed extruder feeds the rubber body into the extrusion die through the side feed hole. In this way, the rubber body is extruded and bonded to the upper and lower surfaces of the galvanized steel sheet. The temperature settings of each zone of the cold feed extruder are as follows:

[0014] Screw One section Second paragraph Three sections Four sections Five sections Machine head 30±5℃ 30±5℃ 40±5℃ 45±5℃ 50±5℃ 65±5℃ 85±5℃

[0015] (5) The rough product of the water stop obtained in step (4) is sent to a vulcanization device for hot air vulcanization, first entering a microwave vulcanization box, and then entering a hot air vulcanization box in sequence. The temperature of the microwave vulcanization box heating tank and the hot air vulcanization box heating tank is controlled at about 400°C, the temperature of the microwave vulcanization box vulcanization tank is controlled at 210±5°C, the temperature of the front hot air vulcanization box vulcanization tank is controlled at 180±5°C, and the temperature of the rear hot air vulcanization box vulcanization tank is controlled at 165±5°C;

[0016] (6) Cooling and curling packaging. The vulcanized waterstop product is cooled to room temperature and then sent to the coiling and packaging machine for curling and packaging and storage.

[0017] The present invention creatively vulcanizes rubber sheets on the upper and lower surfaces of metal plates through an extrusion vulcanization process to obtain a new type of embedded steel-edge rubber waterstop, which effectively improves the structural strength of the steel-edge waterstop and can withstand greater tension and supporting forces. During the construction process, especially during the pouring of concrete, it can ensure that the waterstop does not sag, bend, deflect, etc. due to its own gravity and the impact of pouring concrete. It still maintains a horizontal state without displacement without the need for external support devices, thereby enhancing the anchoring ability of the waterstop, fully exerting the waterproof performance of the waterstop, reducing the construction time for installing the waterstop support device, optimizing the construction process, and having the advantages of simple structure, convenient construction, and stable and reliable.
