Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and more specifically, to a support device for mass concrete in winter construction and its construction method. Background Art

[0002] When carrying out engineering construction in the northern regions of our country, due to tight construction periods, winter construction is often inevitable. When pouring mass concrete in winter, it is necessary to control the temperature drop inside the concrete through methods such as cooling water circulation, and at the same time, it is necessary to carry out comprehensive thermal insulation protection treatment on the concrete pouring site to ensure that the concrete completes strength growth under suitable temperature and humidity conditions.

[0003] In the traditional process of mass concrete construction in winter, it is necessary to separately arrange steel stirrups in three systems. The steel stirrups are respectively used for the support of the foundation steel bars, the erection of the thermal insulation shed support, and the support of the cooling water circulation water pipes. The steel stirrups in the three systems should avoid arc interference; and when the steel stirrups are used for erecting the thermal insulation shed support and the circulation water pipe support, due to the limited bearing capacity of the steel stirrups, it is necessary to set support rods at intervals in the main steel bar mesh of the building structure to support the steel stirrups and prevent the steel stirrups from collapsing due to insufficient bearing capacity when supporting the circulation water pipes and the thermal insulation shed frame.

[0004] The above method requires a large amount of manual laying of steel stirrups and steel support materials, resulting in relatively high material costs, labor costs, and time costs. Moreover, in order to avoid interference between the three systems during construction, it is necessary for construction workers to accurately arrange and fix the construction site, increasing the workload and complexity of the construction and affecting the normal progress of the construction. Summary of the Invention
