Heat preservation and heat insulation building steel structure

Abstract

The invention provides a heat preservation and heat insulation building steel structure, and belongs to the field of building structures. The heat preservation and heat insulation building steel structure includes a steel structure body, a solar air return system and a heat preservation and heat insulation plywood assembly. The steel structure body includes a top steel structure frame and side steel structure frames which are detachably connected, and the heat preservation and heat insulation plywood assembly is arranged inside the top steel structure to be used for isolating heat transmission; the solar air return system includes an expandable light blocker, a heat absorption plate and an air duct, the heat absorption plate is arranged on the upper part of the top steel structure, and theexpandable light blocker is arranged on the side, away from the top steel structure, of the heat absorption plate; and the expandable light blocker includes a cloth rolling driving member, a cloth rolling barrel and light shielding cloth for shielding the heat absorption plate, the driving end of the cloth rolling driving member is matched with the cloth rolling barrel, and one end of the light shading cloth is fixedly connected with the cloth rolling barrel. Through the heat preservation and heat insulation building steel structure, solar energy in winter can be fully utilized to provide heat for an internal space through the solar air return system.

Description

technical field [0001] The invention relates to the field of building structures, in particular to a thermal insulation building steel structure. Background technique [0002] The steel structure workshop mainly refers to the main load-bearing components are composed of steel. Including steel columns, steel beams, steel structure foundations, steel roof trusses (of course, the span of the factory building is relatively large, and basically all steel structure roof trusses are now), steel roofs, and steel structure walls can also be maintained by brick walls. Due to the increase in steel production in our country, many steel structure workshops have begun to be used, which can be divided into light and heavy steel structure workshops. Industrial and civil construction facilities built with steel are called steel structures. [0003] The characteristics of steel structure workshops are: 1. Steel structure buildings are light in weight, high in strength and large in span. 2....
