Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to the construction of a steel structure exterior wall, and specifically to an integral construction process for a steel structure exterior wall. Background Art

[0002] Steel structure exterior wall is one of the structural forms of building exterior wall. Steel structure exterior wall uses high-strength steel as the skeleton and has high wind and earthquake resistance. At the same time, its structure is lighter than the traditional brick-concrete structure and has better bearing capacity. It has many advantages such as good durability and fast construction speed. It is widely used in the construction field and can be applied to various types of buildings such as high-rise buildings, commercial buildings, public buildings and residential buildings.

[0003] The method commonly used for the steel structure exterior wall in the prior art is: after the main frame of the steel structure is built, the upper plate embedded parts are installed inside the prefabricated exterior wall panel, and then the upper column embedded parts are installed inside the steel structure frame column. At this time, the prefabricated exterior wall panel is hoisted by the prepared hoist. When the prefabricated exterior wall panel reaches the predetermined position in the steel structure frame column, the steel bars are welded between the steel structure frame column and the prefabricated exterior wall panel. The steps of this construction method are relatively complicated during operation. If it is the construction of an insulation wall, it is more difficult. In addition, the traditional insulation wall construction relies on splicing insulation boards, and the insulation effect is poor. Summary of the invention

[0004] In order to solve the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a steel structure exterior wall integral construction process, which has strong operability and is conducive to improving construction speed and construction quality.

[0005] The technical solution adopted by the present invention to solve the technical problem is: A steel structure exterior wall integral construction process is provided, comprising the following steps: S1: The main steel structure frame is completed; S2: Use keel structure for leveling; S3: Install outer panels on the outside of the main steel structure frame and keel structure; S4: Arrange a decorative surface layer on the outermost side.

[0006] Furthermore, between step S3 and step S4, the following steps are further included: An inner plate is installed on the outer side of the outer plate, a gap exists between the inner plate and the outer plate, and a heat-insulating sealing material is arranged in the gap.

[0007] Furthermore, the width of the gap is 5-20 cm.

[0008] Furthermore, the thermal insulation sealing material is cement foam or polyurethane foam.

[0009] Furthermore, the outer plate is fixedly connected to the keel structure by bolts.

[0010] Furthermore, the inner plate and the outer plate are fixedly connected by bolts.

[0011] Furthermore, the outer panel is a fireproof cement board, one side of the fireproof cement board is a smooth surface and the other side is a rough surface, and the rough surface faces outwards during installation.

[0012] Furthermore, the inner panel is a fireproof cement board.

[0013] Furthermore, the decorative surface layer is fluorocarbon stone.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. In the overall construction process of the steel structure exterior wall illustrated in the present invention, after the main frame of the steel structure is built, it is leveled through the keel structure. The keel structure is light in weight and high in strength, and it is very easy to operate to adjust the height difference using the keel structure, thereby making the operating steps of the overall construction process simpler and more operable, with low dependence on workers' experience, facilitating standardized operations, and helping to improve construction quality.

[0015] 2. The overall construction process of the steel structure exterior wall in the example of the present invention has a keel structure, so the outer panel can be connected to the keel structure by bolts when installing the outer panel, which is convenient for the installation of the outer panel. If it is an ordinary wall, it is a single-plate structure of one layer of outer panel; if it is an insulation wall, it is a double-plate structure composed of an outer panel and an inner panel, which has strong flexibility.

[0016] 3. In the overall construction process of the steel structure exterior wall of the example of the present invention, a gap is set between the outer plate and the inner plate, and the thermal insulation sealing material is injected into the gap. Compared with the traditional assembled insulation board, the operation method is simpler, and the thermal insulation effect and waterproof effect are improved.

[0017] 4. The overall construction process of the steel structure exterior wall in the example of the present invention is convenient for setting a decorative surface layer on the outermost side of the plate body, which meets people's needs for improving the aesthetics of the building exterior wall. The decorative surface layer is made of fluorocarbon stone, which not only has good aesthetics, but also has superior corrosion resistance and anti-aging properties, and can effectively avoid oxidation peeling and falling off.

[0018] 5. The overall construction process of the steel structure exterior wall in the example of the present invention uses fireproof cement boards for the outer and inner panels, which have good fireproof performance. In combination with other components, the exterior wall as a whole has good thermal insulation, fireproof and corrosion resistance. BRIEF DESCRIPTION OF THE DRAWINGS
