Deformation joint device for simple outer wall of steel structure building and construction method of deformation joint device

Abstract

The invention provides a deformation joint device for a simple outer wall of a steel structure building. The deformation joint device comprises galvanized square pipes symmetrically mounted on the inner sides of a left steel column and a right steel column, an inner cover plate, an outer cover plate and a steel wire mesh, wherein the inner cover plate, the outer cover plate and the steel wire meshcover a deformation joint; a waterproof rubber strip is mounted between the outer cover plate and the inner cover plate, and a rubber water stop belt and a heat preservation and insulation layer arearranged in the deformation joint device; the deformation joint device is complete and attractive in appearance and has the waterproof, fireproof, heat insulation and anti-cracking capacity; when a main structure is greatly deformed, the inner cover plate and the outer cover plate can freely move to adapt to structure deformation of the building under the adverse working conditions such as earthquakes and wind loads; and the deformation joint device is mounted in a layered mode from bottom to top, and mounting of each layer comprises the following steps that S1, the surfaces of the steel columns are cleaned and trimmed; S2, keels are mounted; S3, the inner cover plate is mounted; S4, the rubber water stop belt is mounted; S5, the heat preservation and insulation layer is mounted; S6, the outer cover plate is mounted; S7, the steel wire mesh is covered; and S9, quality inspection and acceptance are conducted. The site construction method is simple and convenient, the construction periodis short, the construction cost is low, and the engineering quality is easy to control.

Description

technical field [0001] The invention relates to a building structure device and a construction method, in particular to a deformation joint device for a simple outer wall of a steel structure building and an installation and construction method thereof. Background technique [0002] The deformation joint device refers to the device that covers the expansion joints of the external wall of the building. The deformation joint device must not only protect the integrity and beauty of the appearance of the joints of the building, but also adapt to the structural deformation of the building under adverse working conditions such as earthquakes and wind loads. When the architectural design requires it, the deformation joints have the ability of waterproof, fire prevention and heat insulation after the corresponding structure is configured. The problems existing in the deformation joints currently used in construction projects are: [0003] 1. At present, most of the deformation join...

AI Technical Summary

Problems solved by technology

[0003] 1. At present, most of the deformation joints used in construction projects are a finished deformation joint device, which is an industrial product. There is no unified national standard or industry standard for the deformation joint device. Most of them are enterprise standards prepared by manufacturers, and some local In this kind of atlas, the deformation joints are generally expressed as general structure and basic requirements, and further in-depth design is required by the design institute;

[0004] 2. The scope of use of the above-mentioned deformation joints is mostly limited to concrete structures or masonry structures, but for steel structures (steel columns on both sides of the expansion joint), there is no corresponding applicable connection structure;

[0005] 3. The finished deformation joints sold on the market generally use a complete set of deformation joints made of aluminum alloy or stainless steel, which is expensive, and its connection structure and installation are relatively complicated. Ordinary residences, office buildings, Buildings such as teaching buildings use such deformation joints, and the cost and construction period of the project are relatively high.

[0006] 4. According to national regulations, the deformation joints of steel structure buildings are 1.5 times that of concrete structures. Therefore, for high-rise steel structure buildings, if deformation joints are set, they will often be particularly wide, which is neither beautiful nor economical.
