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 impor

Embodiment Construction

[0043] The present invention will be further described below with reference to the drawings and specific implementations of a fiber woven mesh reinforced cement-based composite permanent beam template and its manufacturing method. This embodiment is an illustration of the present invention, rather than any limitation on the present invention.

[0044] An interlocking, crack-proof and seepage-proof permanent beam formwork of this embodiment is shown in Figure 1(a)(b)(c)(d). The permanent beam formwork is composed of panels 1 to form the beam formwork. The cross section of the panel is concave, and grooves 11 are distributed on the inner surface.

[0045] The cement-based composite material reinforced by the non-metal fiber woven net is composed of a non-metal fiber net and a cement-based matrix. The non-metal fiber woven net includes: carbon fiber woven net, aramid fiber woven net, alkali-resistant glass fiber woven net, polyethylene Alcohol fiber woven net, polyethylene fiber woven...

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 present invention belongs to a kind of building template, specifically a high-durability permanent template mainly used for beams of industrial and civil building structures, hydraulic structures and harbor structures. It is used as a template during the pouring stage. After forming, it serves as the protective plate and outer protective layer of the structure, and at the same time bears part of the structural load. The invention also relates to a method for making templates. Background technique [0002] At present, in the domestic construction field, beams of industrial and civil building structures, hydraulic structures, and port and sea structures usually use wooden formwork, steel formwork and other forms, which have large consumption, inconvenient disassembly and assembly, high turnover costs, and low utilization rate. And other unfavorable factors. Durability has always been one of the main problems faced by reinforced concrete structures. In ...
