A method of cladding steel

Abstract

The invention relates to a steel wrapping construction method which is applied to a vertical large-area span hidden-frame curtain wall. The steel wrapping construction method specifically includes the following steps: 1, steel structure dimension data of the external wall of a building are measured; 2, position center lines of steel band components and partitioning control lines are snapped; 3, chemical bolts are installed, post-installing embedded parts are fixed, and a steel frame base layer is welded; 4, correction and fixing are carried out, serious-local-deformation sections are heated to be processed, and steel structure parts are riveted to through connection parts of the steel frame base layer after pre-inspection is qualified and numbering is carried out; 5, sundries such as floating dust at the spliced portions are removed, primary cleaning and secondary cleaning are sequentially carried out, and it is guaranteed that splicing is carried out within five minutes after the portions are cleaned; curtain wall silicone structural adhesives, hollow or laminated glass and multi-directional aluminum profile auxiliary frames are spliced and maintained, and scraping blackening processing is carried out on the portions needing to be shielded and hidden. The method is simple and reasonable in technological process and easy to construct, the construction quality can be well controlled, and the quality problems that steel bands are twisted, are not smooth and droop due to the deflection are solved.

Description

Technical field [0001] The invention relates to the field of construction, in particular to a steel-clad construction method. Background technique [0002] In the Anshun Bailing Hilton Hot Spring Hotel project, the base keel of the podium exterior wall design of the project adopts the method of aluminum-clad steel splint keel, and the entire podium has a large glass plate. This project is a five-star hotel, which belongs to the landmark project of Anshun. After completion, it will have the status of becoming the financial center of Anshun. [0003] Before construction, the construction unit, China Construction Third Bureau Oriental Decoration Design Engineering Co., Ltd., analyzed the curtain wall and found that the outer curtain wall of the podium of the project has a large size and irregular building facade. The steel content of the base keel is relatively high. It is installed on the base keel. In the middle, a single steel belt with a length of about 5.4M and a weight of about...

Problems solved by technology

[0003] Before construction, the construction unit China Construction Third Bureau Dongfang Decoration Design Engineering Co., Ltd. analyzed the curtain wall and found that the glass plate size of the outer curtain wall of the podium building of this project is large and the building facade is irregular, and the steel content of the base keel is relatively high. A single steel belt with a length of about 5.4M and a weight of about 450Kg must be erected first. According to the conventional construction method, not only the construction is difficult, but the construction quality is also difficult to guarantee
