Composite heat-preservation steel-reinforced concrete integrated building structure and construction technology

Abstract

The invention discloses a composite heat-preservation steel-reinforced concrete integrated building structure and a construction technology, and belongs to the technical field of buildings. A pair of wallboards are connected through I-shaped steel, and the connecting strength between the wallboards is enhanced; a magnetic covering panel is embedded in the middle of the I-shaped steel, and the magnetic covering panel, an outer heat-preservation plate and an inner heat-preservation plate form an outer heat-preservation cavity and an inner heat-preservation cavity respectively; concrete filler is poured into the outer heat-preservation cavity and the inner heat-preservation cavity, and a concrete pouring layer is formed to form a sandwich heat-preservation structure with the I-shaped steel, so that the mechanical strength of a common wallboard is enhanced, and the heat-preservation and heat-insulation performance of the common wallboard is enhanced; and in addition, a plurality of rigid hot-melting bags are distributed on the inner end face of the outer heat-preservation plate, after the concrete filler is poured, the rigid hot-melting bags are subjected to hot melting to release magnetic-attached glass beads, and under the magnetic attraction effect of the magnetic covering panel, the magnetic-attached glass beads are uniformly diffused into gaps of the concrete filler, so that the heat-preservation and heat-insulation effects of the outer heat-preservation cavity are further enhanced.

Description

technical field [0001] The invention relates to the field of construction technology, more specifically, to a composite thermal insulation steel-reinforced concrete integrated building structure and construction technology. Background technique [0002] Construction industrialization, housing industrialization, and urbanization require active promotion of prefabricated construction. The exterior wall building is the main enclosure structure of the building. It is an important research field for building material renewal and building energy conservation. The degree of assembly is also crucial to the assessment of the level of building industrialization. [0003] For prefabricated exterior wall panels, it is required to meet the mechanical properties and at the same time have excellent thermal insulation, heat insulation, sound insulation, waterproof and other properties. In the past, the external wall panels composed of a single material often failed to meet the comprehensiv...

Problems solved by technology

In the past, the external wall panels composed of a single material often failed to meet the comprehensive requirements of the above performance, especially the requirements for thermal insulation and heat insulation; in addition, the connection between the wall panels and the structural beams could not guarantee a strong mechanical connection effect, which was difficult to meet High-strength requirements for building structures
