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 present invention belongs to a kind of 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 in the pouring stage. After pouring and forming, it doubles as the protective plate and outer protective layer of the structure, and bears part of the structural load at the same time. Background technique

[0002] At present, in the domestic construction field, the pillars of industrial and civil building structures, hydraulic structures, and harbor and sea structures usually use wooden formwork, steel formwork and other formwork, which has large consumption, inconvenient disassembly and assembly, high turnover cost, and utilization rate. Low-level disadvantages. Durability has always been one of the main problems faced by reinforced concrete structures. In the traditional structure, the surface of or...
