Abstract

The invention provides a heat preservation composite formwork and a concrete construction method applied to a strong wind forest area, and belongs to the technical field of civil construction. The heat preservation composite formwork comprises a formwork body, heating units and a plurality of supporting units; concrete is poured into the formwork body, a plurality of supporting units are arrangedon the periphery of the formwork body and used for supporting the formwork body, and a heat preservation layer is arranged between every two adjacent supporting units; a plurality of fixing plates arearranged between the formwork body and the supporting units; the heating units are arranged on the fixing plates and used for heating concrete poured in the formwork body. The invention further provides the concrete construction method applied to the strong wind forest area, and the construction method adopts the heat preservation composite formwork. According to the heat preservation composite formwork and the concrete construction method applied to the strong wind forest area, the formwork body is not prone to deformation in the concrete pouring process, and the internal and external temperature difference of the concrete in the pouring process is reduced.

Description

Technical field [0001] The invention belongs to the technical field of civil construction, and more specifically, relates to a thermal insulation composite formwork and a construction method for concrete in strong wind forest areas using the thermal insulation composite formwork. Background technique [0002] In recent years, with the acceleration of infrastructure construction and the increasing demand for social development, a large number of high-investment and difficult bridge projects have gradually been completed and put into use. Bridge construction has the characteristics of long construction period, high technical difficulty, and poor construction environment, especially in winter forest areas with strong winds. Due to the low temperature, the hydration of cement weakens and the hardening speed of concrete slows down, which causes the loss of concrete strength and durability. If the temperature difference of the concrete member itself is large, temperature cracks will a...
