Waterproof split bolt capable of adjusting width between formworks

Abstract

The invention provides a waterproof split bolt capable of adjusting the width between formworks, and belongs to the technical field of formwork construction and impermeable construction. The waterproof split bolt comprises a split screw rod, two ends of the split screw rod are in threaded connection with formwork waterproof parts, and the formwork waterproof parts are in threaded connection with fastening accessories. A water seepage waterproof part is arranged in the middle of the split screw rod and comprises a water stop steel ring and a rubber hollow ring, the water stop steel ring is clamped with the rubber hollow ring, the rubber hollow ring is connected with the split screw rod in a sleeved mode, and a water-absorbent resin ring and a sealant filling layer are arranged in the middle of the rubber hollow ring. Compared with the prior art, two waterproof devices are adopted, the width between the formworks can be flexibly adjusted, and the waterproof split bolt has the advantages of being efficient in waterproof performance and efficient in formwork installation.

Description

technical field [0001] The invention belongs to the technical field of formwork construction and anti-seepage construction, and in particular relates to a waterproof half-stay bolt capable of adjusting the width between formworks. Background technique [0002] The pull bolt refers to a tie structure used between the inner and outer formwork of the wall. It is used to bear the lateral pressure and other loads of the concrete to ensure that the distance between the inner and outer formwork can meet the design requirements. The fulcrum of the supporting structure plays an important role, so the arrangement of the tie bolts has a great influence on the integrity, stiffness and strength of the formwork structure. [0003] Before the wall concrete is poured, it is necessary to use formwork to control the shape of the concrete section, and to fix the formwork with pull bolts. For walls with anti-seepage requirements, water is easy to seep along the connection surface between the pu...

Problems solved by technology

[0004] Because the traditional water-stop rubber ring is directly connected to the pull screw, water seepage is prone to occur, and the weld seam welded between the water-stop steel plate and the pull screw is prone to cracks during low-temperature cold and brittle or long-term use, which leads to seepage , in addition, in the application process of traditional tension bolts, the concrete pouring width needs to be manually adjusted for the distance between the templates, which is not efficient and difficult to control
