A kind of preparation method of trc permanent formwork beam or column

Abstract

The invention discloses a preparing method for a TRC permanent formwork beam or column. Multiple TRC single plates are prepared from fiber woven meshes and fine concrete, then the multiple TRC singleplates are assembled into a permanent formwork for pouring the beam or column, then concrete is poured, and maintenance is conducted till specified conditions are achieved; multiple inversed-T-shapedTRC single plates are prepared from fiber woven meshes and fine concrete, then the multiple TRC single plates are assembled into a permanent formwork for the beam or column, concrete is poured, and maintenance is conducted till specified conditions are achieved. The construction technology for assembling and disassembling formworks for cast-in-place reinforced concrete structures is simplified, building efficiency can be improved, the cost can be reduced, natural resources can be saved, and building industrialization can be promoted; the TRC assembled formwork has the formwork function and canparticipate in stressing as a part of the structures, reinforcing steel bars can be protected, and the durability and effective bearing capacity and ductility of structural members can be improved; as for the TRC assembled formwork, the single plates are light in self weight, convenience is brought to transportation and construction, and broad application prospects are achieved.

Description

technical field [0001] The invention relates to a method for preparing reinforced concrete beams and columns, in particular to a method for preparing a novel TRC permanent formwork beam or column suitable for construction of reinforced concrete structures. The utility model belongs to the technical field of concrete reinforcement. Background technique [0002] Formwork is an important construction tool with a large quantity and a wide range in the construction of concrete structures. From an economic point of view, formwork engineering accounts for 20% to 30% of the cost of reinforced concrete structures, 30% to 40% of labor, and about 50% of the construction period. It can be seen that formwork engineering occupies a very important position in civil engineering construction. [0003] The shortcomings of traditional formwork: (1) need to consume a lot of formwork materials (including wood, bamboo and steel, etc.), and the turnover of these materials is usually only three ti...

Problems solved by technology

[0003] The shortcomings of traditional formwork: (1) need to consume a lot of formwork materials (including wood, bamboo and steel, etc.), and the turnover of these materials is usually only three times, which will lead to excessive use of natural resources; (2) formwork During the production, installation and demolition of the formwork, the amount of work is relatively large, and due to the low turnover rate of the formwork during construction, the cost of the project increases, the labor force is large, and the construction period is long.

[0005] The application number is CN201210246293.2, which discloses a preparation method of a reinforced concrete beam with a TRC permanent bottom form, but the TRC permanent formwork of this application is only used as the bottom form of the beam, and the side formwork still needs to be supported when pouring concrete in the later stage; application number CN201310178191.6 discloses a method for making a "U"-shaped TRC permanent template, but the cement-based composite material has high brittleness, which is not conducive to exerting the ultimate bearing capacity of the woven mesh, and the "U"-shaped template Non-assembled; the application number is CN201610803669.3, which discloses a method for making TRC permanent formwork composite beams, but does not give a specific method for making the formwork
