Fiber woven mesh reinforced cement-based composite material permanent beam formwork and manufacturing method thereof

Abstract

The invention discloses a permanent beam template made of a fiber woven mesh reinforced cement based composite material and a method for manufacturing the permanent beam template. Sections of the template are concave, and grooves are formed inside the sections. The permanent beam templates serve as beam templates in the beam pouring stage of structures such as industrial and civil building structures, hydraulic structures and harbor structures and also serve as protecting plates and outer protecting layers for the structures after pouring forming to bear partial loads. The template is made of the non-metallic fiber woven mesh reinforced cement based composite material, a steel wire mesh reinforced cement based composite material and the like, and the permanent beam template has the advantages of being simple to manufacture, convenient to use, high in durability and good in cracking control performance.

Description

technical field [0001] The invention belongs to a building formwork, specifically a high-durability permanent formwork mainly used for beams in industrial and civil building structures, hydraulic structures, and harbor and sea structures. It is used as a formwork in the pouring stage. After forming, it also serves as the protective plate and outer protective layer of the structure, and bears part of the structural load at the same time. The invention also relates to a method for making the template. Background technique [0002] At present, in the field of domestic construction, the beams 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 low utilization rate. and other unfavorable factors. Durability has always been one of the main problems faced by reinforced concrete stru...

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
