An interlocking formwork for an anti-crack and anti-seepage permanent column

Abstract

The invention discloses a mutually-buckled type assembled anti-cracking impermeable permanent column template. Adjacent corner panels are buckled and are connected through an adhesive. The mutually-buckled type assembled anti-cracking impermeable permanent column template can be taken as a column template in a column pouring stage of structures, such as industrial and civil building structures, hydraulic structures, port structures and the like, and can be both taken as a protecting plate and an outer protecting layer of the structure after pouring molding, and can bear a part of load. According to the invention, the template can be made by the following different kinds of materials including a self-compaction ultra-high toughness cement based cementitious material (self-compaction UHTCC), a nonmetallic fiber woven net, a chopped fiber combined enhanced cement based composite material, a steel mesh chopped fiber combined enhanced cement based composite material and the like, and the mutually-buckled type assembled anti-cracking impermeable permanent column template has the characteristics of simple production, convenience for use, high durability, and capability of controlling crack developing.

Description

technical field [0001] The invention belongs to a building formwork, specifically a high-durability permanent formwork mainly used for columns of industrial and civil building structures, hydraulic structures, and harbor and sea structures. It is used as a formwork during the pouring stage. After pouring and forming, it can also be used as the protective plate and outer protective layer of the structure, and bear part of the structural load at the same time. Background technique [0002] At present, in the field of domestic construction, the columns of industrial and civil building structures, hydraulic structures, and harbor and sea structures usually use wooden formwork, steel formwork and other formwork, which has the disadvantages of large consumption, inconvenient disassembly and assembly, high turnover costs, and low utilization rate. low disadvantages. Durability has always been one of the main problems faced by reinforced concrete structures. In the traditional str...

AI Technical Summary

Problems solved by technology

In the traditional structure, the surface of ordinary concrete is naturally exposed, and its durability is low. At present, about 50% of the houses in my country have entered the aging stage, that is, 2.34 billion square meters of buildings are facing durability problems.

In addition, designing with crack resistance as the control condition is an important feature that distinguishes hydraulic structures, port and sea structures, etc. from other types of building structures. The problem of easy cracking of ordinary concrete will not only affect the normal work of hydraulic structures, but also affect their durability. performance and service life, and even affect the safe operation of the structure
