Three-dimensional adjustable assembled light-weight batten outer wall system and construction method thereof

Abstract

The invention belongs to the field of building engineering, and particularly relates to a three-dimensional adjustable assembled light-weight batten outer wall system used for an assembled steel structure building. The three-dimensional adjustable assembled light-weight batten outer wall system is used for the assembled steel structure building, and comprises light-weight battens, sleeves, connecting screw bolts, supporting elements, tensioning elements, an outer side heat insulation decoration plate system and an inner side veneer system, wherein one sleeve is respectively arranged in a position, near the batten end part, of each of the upper and lower ends of each light-weight batten; the lower end of each light-weight batten is connected with a lower layer framework steel beam through the sleeves, the connecting screw bolts and the supporting elements; the three-dimensional adjustability of the lower end connection of the light-weight battens in the thickness, width and height directions of a wall plate is realized; the upper end of each light-weight batten is connected with an upper layer framework steel beam through the sleeves, the connecting screw bolts and the tensioning rods; and the three-dimensional adjustability of the upper end connection of the light-weight battens in the thickness, width and height directions of the wall plate is realized. The requirements on thethermal performance of the wall body in cold and severe cold areas are met; the problem of heavy object nailing and hanging on a wall body and groove formation for pipeline arrangement are solved; the three-dimensional adjustability of the wall plate installation is realized; the requirement on the installation precision of the wall plate is met; and the construction efficiency is improved.

Description

technical field [0001] The invention belongs to the field of construction engineering, and in particular relates to a three-dimensional adjustable light slat exterior wall system and a construction method thereof for a prefabricated steel structure building. Background technique [0002] Prefabricated steel structure buildings have the advantages of high bearing capacity, good seismic performance, high level of industrialization, and environmental protection, and are an important way to realize the industrialization of buildings. At present, the exterior wall systems applied to prefabricated steel structure buildings mainly include: self-insulation lightweight slat exterior wall system, light steel keel composite panel exterior wall system, and prefabricated concrete sandwich insulation large-slab exterior wall system. However, the above three external wall systems applied to prefabricated steel structures still have the following technical problems: [0003] 1. The self-in...

AI Technical Summary

Problems solved by technology

The structure of the wall panel system is complex, the cost is high, and the cold-formed thin-walled steel members are directly connected to the panel, which is easy to form a cold bridge in the wall, which affects the thermal insulation effect of the wall

In addition, the thickness of the panel on the inner side of the wall frame keel is small, usually 9-15mm, and it is difficult to nail and hang heavy objects on the wall

[0005] 3. The inner and outer leaf concrete slabs of the prefabricated concrete sandwich insulation slab are usually connected by stainless steel anchors or fiber reinforced plastic (FRP) anchors that penetrate the sandwich insulation layer. The shear stiffness of these two types of connectors It is too small to realize the combination of internal and external plates, and the stainless steel tension joints will also cause problems of cold bridges and condensation; the fiber reinforced plastic (FRP) tension joints also have problems such as aging and poor fire resistance; in addition, the The inner and outer slabs of the exterior wall system are made of concrete, which is heavy and requires a special crane for installation. The installation and adjustment of the wall panels is difficult, and the advantages of light weight, high bearing capacity and good seismic performance of the prefabricated steel structure building cannot be fully utilized.

[0006] Due to the above-mentioned problems in the exterior wall system applied to prefabricated steel structure buildings, it affects the popularization and application of prefabricated steel structure buildings and limits the development of building industrialization
