Description

Technical Field

[0001] The invention relates to the technical field of building curtain wall construction, in particular to a clay brick and glass brick mixed hanging curtain wall system and a construction method thereof. Background Art

[0002] With the rapid progress of science and technology in my country's construction industry and the development of diversified buildings, more and more local historical buildings are built with local traditional customs. The design of the building facade should continue the basic theme of local regional culture and reflect the simple and powerful shape of the building. Different bricklaying methods should be used to show the diversity of the facades of traditional buildings in the streets and alleys, so that the building seems to grow out of the historical architectural relics, fully reflecting the design concept of combining the old and the new and the virtual and the real.

[0003] In order to realize the design concept of combining the old and the new and the virtual and the real on the facade of the historical building, we have to use a mixed masonry method of clay bricks and glass bricks to achieve it, but the modern technology is only a single clay brick hanging construction technology, which is difficult to meet the design requirements. As a new technical means, the construction method of mixed hanging curtain wall of clay bricks and glass bricks solves the design concept of using modern technology to realize the characteristic construction of historical buildings combined with local traditional folk customs. It not only meets the durability, safety and aesthetics of the building, but also meets the national advocacy of energy conservation and sustainable development. It combines modern hanging technology with curtain wall support system. It is an exterior wall decoration construction method. While ensuring the exterior wall decoration effect, it also takes into account the stability of the entire exterior wall system and building energy conservation. It is more suitable for multi-story buildings and historical buildings that need to use clay bricks and other brick masonry mixed masonry curtain walls as exterior wall decoration. At the same time, in the construction process of mixed hanging curtain walls of historical buildings, waste will be generated due to improper on-site brick cutting, which will increase the use of building materials. In addition, workers cutting bricks on site will also cause environmental pollution and affect the construction period. Specifically, its shortcomings are as follows:

[0004] ① The hollow ratio of clay bricks is small, their weight is heavy, the steel content of the curtain wall structure is large, and the overall stability of the structure is poor.

[0005] ②The curtain wall system is closely attached to the main structure, which is not conducive to later maintenance.

[0006] ③ The 0-180° inclined corner bricks of the curtain wall are cut on site, and the brick shapes are not standardized and uniform, which makes it difficult to meet the requirements of staggered masonry.

[0007] ④ The beveled corner bricks and half bricks of clay bricks are all cut and processed on-site by workers. Improper on-site brick cutting will lead to the generation of waste, increase the use of building materials, cause environmental pollution, and affect the construction period.

[0008] The present invention is proposed in view of the above research background, and aims to provide a clay brick and glass brick mixed hanging curtain wall system and a construction method thereof to meet actual design and use needs. Summary of the invention

[0009] In view of the above-mentioned deficiencies in the background technology, the object of the present invention is to provide a clay brick and glass brick mixed hanging curtain wall system and a construction method thereof, which has the characteristics of reasonable structural design, reduced cost and convenient construction. It can not only solve the problem of large overall steel content and poor overall structural stability of the clay brick and glass brick mixed hanging curtain wall structure, but also solve the problem of high requirements for staggered masonry and installation of curtain walls and convenient overall maintenance in the later stage, thereby achieving the purpose of building energy saving.

[0023] 10) Detailed node processing, grouting, and acceptance: Carry out detailed finishing treatment on the vertical main keel foundation, doors and windows, and roof parapets, and clean the wall surface. After the maintenance of clay tiles and glass tiles, use special grouting agent to grout the tiles in time. The depth should not be less than 5mm, and the seam surface should be recessed into the tile facade by not less than 0.5mm. The acceptance includes judging whether the exposed glue seams of the curtain wall are horizontal and vertical, whether the color of the clay tiles is uniform and the surface is clean and pollution-free, and whether the overall surface of the curtain wall is flat. Acceptance can only be qualified after it fully meets the standards.

[0024] As a further optimization of the above scheme, the design of the curtain wall structure cantilever panel in the step 1) includes: the curtain wall main body design unit determines the foundation form of the structure cantilever panel according to the load parameter requirements and the design drawings, and the foundation form of the structure cantilever panel is a corbel cantilever or a straight section cantilever panel; the design of the main purlin and secondary purlin of the curtain wall includes determining the angle steel spacing transmitted by the clay bricks and glass bricks to the vertical main purlins, the vertical purlin specifications and dimensions, the chemical anchor specifications and the purlin connection method according to the stress conditions of the chemical anchors, the end weld strength requirements, and the inertia moments of the main purlins and secondary purlins; the layout design of the clay bricks and glass bricks of the external curtain wall includes completing the facade layout design of door and window openings, parapets, ground junctions and facade entry and exit parts under the established clay brick and glass brick modulus and vertical and horizontal brick joints design requirements, so as to meet the requirements of modulus and aesthetics.
