Embodiment Construction
[0033] The following is attached Figure 1-4 The application is described in further detail.
[0034] The embodiment of the present application discloses a steel-concrete structure of a prefabricated green building. refer to figure 1 , the steel-concrete structure of the prefabricated green house building includes an outer steel pipe 1 and an inner steel pipe 2, the inner steel pipe 2 is located inside the outer steel pipe 1, and the outer steel pipe 1 and the inner steel pipe 2 are coaxial and flush at both ends. Both the outer steel pipe 1 and the inner steel pipe 2 are square pipes, and the inner wall of the outer steel pipe 1 and the outer wall of the inner steel pipe 2 enclose a space in the shape of a "mouth". No concrete is poured into this space, and only the inner steel pipe 2 is poured with concrete. Before concrete is poured into the inner steel pipe 2, a reinforcing cage needs to be inserted, and the reinforcing cage has the same length as the steel-concrete beam...

The invention relates to the field of constructional engineering, in particular to a steel-concrete structure of a fabricated green house building. The steel-concrete structure comprises an outer steel pipe, a coaxial inner steel pipe is arranged in the outer steel pipe, a distance is kept between the outer wall of the outer steel pipe and the inner wall of the inner steel pipe, concrete is poured into the inner steel pipe, a distance retainer is connected between the inner steel pipe and the outer steel pipe, a heat conduction metal pipe penetrates through the distance retainer, an electric heating rod is arranged in the heat conduction metal pipe, and a heat preservation material or a heating device is arranged between the outer steel pipe and the inner steel pipe. The double-layer steel pipe structure of the inner steel pipe and the outer steel pipe is adopted, an air heat insulation layer is arranged between the inner steel pipe and the outer steel pipe, a heat preservation material or a heating device can be arranged in the air heat insulation layer, and therefore concrete in the inner steel pipe cannot be frozen; and the use amount of the concrete is greatly reduced, the setting time of the concrete is greatly shortened, and the time for protecting the concrete from being frozen before the concrete is set is shortened, so that the construction cost is reduced.
Description
technical field [0001] The present application relates to the field of construction engineering, in particular to a steel-concrete structure of an assembled green house building. Background technique [0002] Compared with concrete structures, steel structure system components can be produced in a standardized manner, with short construction periods, easy quality control, and recyclable materials. It is an excellent structural system. Steel structure buildings usually consist of beams, columns, trusses and other components made of section steel and steel plates to form a load-bearing structure, which together with enclosure structures such as roofs, floors and walls form the entire building. Compared with traditional concrete buildings, steel structure buildings use steel plates or section steel instead of reinforced concrete, which has higher strength and better earthquake resistance. [0003] However, in cold regions, steel structures that have been exposed to low tempera...
