Abstract

The invention discloses an ECC non-dismantling formwork, a concrete beam based on the formwork and a construction method thereof, and belongs to the technical field of building material construction.The ECC non-dismantling formwork comprises a formwork body, the formwork body is made of cement-based composite materials, the outer side surface of the formwork body is a smooth surface, the inner side surface of the formwork body is a smooth surface, a roughened surface, a concave and convex surface or a sand blasting surface rough surface, an enhancement layer is arranged in the formwork body,and the enhancement layer is a steel strand mesh, a fiber mesh, an FRP mesh, an FRP bar or steel bar. The ECC non-dismantling formwork is not dismantled after the formwork concrete is poured, but is used as a part of a concrete structure, load is borne, some special functions, such as heat preservation, heat insulation and increasing the durability of the concrete structure are further achieved, and when the formwork is used for beam fabrication, the advantages that the construction procedures are simplified, operation is simple and convenient, labor conditions are improved, the amount of formwork support and dismantling is saved, and the construction progress is accelerated are achieved.

Description

technical field

[0001] The invention belongs to the technical field of building material construction, and in particular relates to an ECC demolition-free formwork, a concrete beam based on the formwork and a construction method thereof. Background technique

[0002] In the current field of civil engineering, most of the pouring forms for concrete structures are wooden formwork, and the turnover rate of wooden formwork is extremely low, resulting in serious waste, which will aggravate the negative impacts such as environmental pollution and social and economic losses; The popularization and application of aluminum and steel molds at this stage has effectively alleviated the waste of timber resources and the state of tight supply. However, the cost of aluminum molds and steel molds is relatively high, and losses will also occur during the turnover process. On the other hand, these two kinds of formworks all need to be demolished, the process is relatively complicated, and th...
