Description
Technical Field
The invention relates to the technical field of building materials, in particular to a light steel light concrete structure which has good sound and heat insulation effects, high pouring efficiency, light weight and high strength of constructed buildings such as walls, roofs and floors, saves metal materials, is convenient for pre-burying wiring, and has high bearing capacity, impact resistance and deformation resistance.
Background
The light steel light concrete structure is a novel structure system which combines light steel prefabrication assembly and light concrete cast-in-place by taking thin-wall light steel and light concrete as main materials and taking a quickly built light steel keel as a support. The light steel keel has good rigidity and bearing performance, can bear construction load, and creates conditions for simplifying the template installation process and structure; the lightweight concrete is mainly prepared by casting in-situ or prefabricating in factories, such as but not limited to modified polyphenyl particles, perlite particles, ceramsite and the like, so that the structural integrity and the seismic performance are improved, the obtained solid wall, roof and floor have good sound insulation and fire resistance, and the defect of poor living comfort of hollow walls and the like is overcome; the light steel keel and the light concrete have good cooperative working performance, can give full play to the advantages of two materials, and save steel compared with a light steel structure and a reinforced concrete structure; in addition, the lightweight concrete material has good thermal performance, the thermal insulation performance of the constructed building is superior to that of a concrete structure and a masonry structure, and the structural thermal insulation integration of the building can be realized in a specific climate zone. Therefore, light steel light concrete structures are currently being gradually applied on a large scale. However, since the light steel lightweight concrete structure is made of a metal material mainly including the light steel keel, and the metal has the characteristics of poor sound insulation effect and low heat insulation performance, when the light steel keel is used as a stress component of the light steel lightweight concrete structure, a building body constructed by the light steel lightweight concrete structure inevitably has the problems of poor sound insulation effect and low heat insulation performance. In the prior art, for places with high requirements on sound insulation and heat insulation, the light steel light concrete structure usually adopts modes of thickening walls, increasing the number of partition plates or arranging double-layer walls and the like to solve the problems of poor sound insulation effect and low heat insulation performance, but also causes the problems of complicated construction, increased engineering quantity, increased cost, reduced space area utilization rate and the like. At present, a method for forming holes on a thin-wall light steel web of a light steel keel is also used for increasing the propagation path of sound or heat, so that the propagation resistance is increased, and the aims of sound insulation and heat insulation of buildings such as walls are improved. However, the opened holes are smooth holes, the matching of the opening parameters is not reasonable, and the opening rate of the web is too large or too small, so that the bearing capacity and rigidity of the building bodies such as the wall body and the like after the thin-wall light steel is opened with the holes are obviously reduced, and the problems that the thickness of the web needs to be increased and the size needs to be increased to make up exist.
