Description
Technical Field
The invention belongs to the field of building engineering, and particularly relates to a three-dimensional adjustable light batten outer wall system for an assembled steel structure building and a construction method thereof.
Background
The assembled steel structure building has the advantages of high bearing capacity, good anti-seismic performance, high industrialization level, environmental protection and the like, and is an important way for realizing building industrialization. The external wall system applied to the fabricated steel structure building at present mainly has: the self-heat-preservation light batten outer wall system comprises a self-heat-preservation light batten outer wall system, a light steel keel composite board outer wall system and a precast concrete sandwich heat-preservation large plate outer wall system. However, the three external wall systems applied to the fabricated steel structure building have the following technical problems:
1. the self-heat-preservation light batten outer wall system mainly takes autoclaved aerated concrete slabs, ceramsite concrete slabs, foamed concrete slabs and the like as outer wall plates. Compared with the traditional wall material, the self-heat-insulation light batten outer wall material is small in heat conductivity coefficient and can play a certain role in heat insulation. However, with the promulgation and implementation of 75% energy-saving standards, the single-material light batten outer wall system cannot meet the requirements of building energy-saving design standards on the thermal performance of the wall body, and the above light battens also have the problem of freeze-thaw damage. At present, in cold and severe cold areas, the light-weight lath is usually only used as an inner wallboard or a base wallboard needing an additional outer wall external insulation system.
2. The light steel keel composite board outer wall system is formed by forming a wall frame by cold-formed thin-wall steel members, filling heat-insulating materials in the wall frame, nailing and hanging panels at two sides and making a decorative layer. The wallboard system is complex in structure and high in manufacturing cost, and the cold-formed thin-walled steel members are directly connected with the panel, so that a cold bridge is easily formed in the wall body, and the heat insulation effect of the wall body is influenced. In addition, the panel thickness of the indoor one side of wall frame fossil fragments is less, is 9 ~ 15mm usually, and it is difficult to nail the string heavy object on the wall body.
3. The inner leaf concrete slabs and the outer leaf concrete slabs of the precast concrete sandwich heat-insulation large slab are usually connected by stainless steel tie pieces or Fiber Reinforced Plastic (FRP) tie pieces penetrating through the sandwich heat-insulation layer, the shear rigidity of the two types of the tie pieces is small, the combined stress action of the inner slab and the outer slab cannot be realized, and the stainless steel tie pieces can bring about the problems of cold bridge and dewing; the Fiber Reinforced Plastic (FRP) pulling piece also has the problems of poor aging and fire resistance and the like; in addition, the inner and outer blades of the outer wall system are all made of concrete, have heavy self-weight, need to be installed by a special crane, have high difficulty in installing and adjusting the wall plate, and do not have the advantages of light self-weight, high bearing capacity and good anti-seismic performance of the fabricated steel structure building.
The outer wall system applied to the assembly type steel structure building has the problems, so that the popularization and the application of the assembly type steel structure building are influenced, and the development of building industrialization is limited.

4. The light batten outer wall system adopts a cavity-free structure, and the interface agent is sprayed on the surface of the light batten base layer, so that the bonding strength between the heat-insulating decorative layer and the base layer is improved; by additionally arranging the anchoring piece with the polyurethane heat-insulating pad to be mechanically fixed with the wallboard base layer, the connection safety of the heat-insulating decorative plate and the base layer is improved, and the problems of cold bridge and dewing existing in the conventional connection structure are solved.
