Description
Technical Field
The invention belongs to the technical field of building material construction, and particularly relates to an ECC (error correction code) disassembly-free template, a concrete beam based on the template and a construction method of the concrete beam.

However, the cost of the aluminum die and the steel die is high, and the loss also occurs in the circulation process. On the other hand, the two templates are required to be disassembled, the process is complex, the construction site is occupied, and the construction progress is influenced. Therefore, the development, popularization and application of the non-dismantling template have good economic benefit, social benefit and wide market prospect no matter starting from the template industry or promoting the development of the whole green building.
At present, certain progress and achievements are made in the aspect of the disassembly-free template at home and abroad, and the disassembly-free template has the advantages and the defects that:
(1) the reinforced concrete disassembly-free template is mature and economic in development, but the beam template is heavy in weight and inconvenient to transport and install, and the stress bar is installed in the prefabricated template, so that the integrity of a superposed member is insufficient;
(2) the profiled steel sheet type disassembly-free template has light weight, quick installation and good construction quality, but has weak fire resistance, high manufacturing cost and difficult guarantee of integrity;
(3) the fiber disassembly-free template is the development direction of the current disassembly-free template, the fiber in the template is used for replacing the traditional reinforcing bar to enhance the mechanical property of the beam template, but the research of the fiber disassembly-free template is started late, and the current development is not mature;
(4) exempt from to tear open template technical innovation not enough, exempt from to tear open the template and accomplish to provide additional function for the structure, also can provide intensity for the structure, ensure the ductility, protect effects such as inside reinforcing bar. Most technical innovations of the domestic non-dismantling formwork are concentrated on a composite structure of composite materials and concrete, but the design is expensive, and the FRP materials are exposed in the environment, so that the aging and damage of the FRP materials are accelerated. Although the cost is reduced, the non-dismantling formwork-short fiber cement-based material has limited structure reinforcing effect, and the thickness required when the non-dismantling formwork reaches the use strength is larger, so that the transportation and the construction are inconvenient. The development of a novel disassembly-free template is urgently needed, and the usability, the functionality and the economy are achieved;
ECC is a fiber reinforced cement-based composite that exhibits high ductility under tensile and shear loads through a systematic micromechanical design. However, the cost price of ECC materials is far higher than that of common concrete at present, so that the ECC materials can only be used for key parts of a structure. The research of the prior literature indicates that ECC is an ideal choice for manufacturing the concrete template, and the adoption of ECC material as the non-dismantling template of the concrete structure can greatly improve the crack resistance, the bearing capacity, the ductility, the energy consumption and the crack form of the structure.
The ECC non-dismantling template is formed by combining a CFRP grid and an ECC to reinforce the ECC, the structural form can obviously improve the toughness of the material, improve the crack control capability of the material, enable cracks to develop more densely, realize harmless dispersion of concrete cracks, obtain higher bearing capacity, and solve the problems of poor fire resistance, poor steam permeability and easy peeling of the traditional FRP sheet material reinforcing method and the defects of easy cracking, poor ductility and the like of the traditional cement-based material.
Based on above background, this patent has proposed an exempt from to tear open ECC and has exempted from to tear open template, based on the concrete beam of this template, adopts the ECC of high ductility, high tensile strength ability to exempt from to tear open the template and regard as the template of pouring of the inside concrete of structure, both reducible template quantity can play better guard action to inner structure when reducing construction cost again to reach the accuse and split and improve structural performance's purpose.
