Problems solved by technology

However, when the combined permanent formwork is used, there will inevitably be formwork seams. The formwork joints are the weak link of the structural members, and the leakage caused by them is also the main problem affecting the durability of the structure. How to effectively solve this problem The problem is one of the key issues of whether the ultra-high performance concrete combined permanent formwork can be used

Abstract

The invention belongs to the technical field of building materials, and discloses a quick positioning highly waterproof ultra-high-performance concrete combined permanent template. The outer side of apermanent template is flat or curved, and the inner side is ribbed; the four side portions are thickened, and a tongue-and-groove is formed, and a lap joint of the tongue-and-groove is hydrophobic; after the tongue-and-groove is lap jointed, a caulking groove smaller on the outside and bigger on the inside is formed in the outer side of a template; a water-expanding rubber strip is arranged at the tongue-and-groove to improve waterproofness; and positioning platesare arranged at the upper and lower side portions for quick positioning. According to the high-performance concrete combined permanent template, a tongue-and-groove design is used on all four sides, a highly waterproof system is formed by using an ultra-high-performance concrete caulking agent, a hydrophobic surface and a hydrophobic paste, and a water-expanding rubber strip, and durability can be effectively improved; and the positioning plate is used for quick positioning, and the construction speed is improved.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a fast-positioning high-waterproof ultra-high-performance concrete combined permanent formwork. Background technique [0002] Formwork engineering develops along with the development of concrete engineering, and has a long history both at home and abroad. The permanent formwork, also known as one-time consumption formwork, means that the formwork will not be dismantled after the cast-in-place concrete structure is poured, and the permanent formwork is used as a protective layer or combined with the cast-in-place structure to form a common force-bearing member. It has the advantages of simplified construction process, easy operation, improved working conditions, no or less formwork support, saving formwork support and dismantling labor, and speeding up construction progress. At present, the main materials are steel and fiber reinforced plastics. Although th...
