Description

Technical Field

[0001] The invention relates to the technical field of exterior wall concrete texture construction, in particular to a method for constructing special-shaped exterior wall concrete texture of a high-rise residential building. Background Art

[0002] With the increasing development of urban socio-economic development, newly constructed commercial complexes have become popular leisure and entertainment venues for modern residents. High-rise residential buildings, predominantly employing shear wall concrete structures, feature novel and unique facade shapes and diverse forms. Currently, the exterior concrete walls of high-rise residential buildings are designed with a 0-50mm thick triangular prism texture, separated by 100mm wide grooves, and staggered odd and even wall textures.

[0003] Using lightweight polymer materials to secure the exterior concrete surface in a secondary process can lead to detachment over time, making repair difficult and costly. Traditional wooden formwork, however, makes it impossible to reinforce the 0-50mm triangular prisms and 100mm-wide grooves in the exterior wall texture. Solving the construction challenge of single-step molding of the special-shaped triangular prisms in the exterior walls of high-rise residential buildings is a technical topic worthy of research. Summary of the Invention

[0004] In response to the above-mentioned existing technologies, the present invention proposes a method for constructing concrete texture of special-shaped exterior walls of high-rise residential buildings, aiming to solve the problems of long secondary operation period, high cost and easy falling off of traditional lightweight polymer materials in the construction of special-shaped exterior walls of high-rise residential buildings, and the inability to reinforce traditional wooden formwork and high maintenance cost.

Connection of inner and outer formwork of exterior wall: Hoist the spliced ​​inner and outer formwork of exterior wall to the inner and outer edges of the exterior wall, and install pull tabs to connect the inner and outer formwork of exterior wall; S5. Reinforce the inner and outer formwork of the exterior wall: Install three horizontal square tubes on the inner and outer formwork of the exterior wall using square tube buckles, and install vertical back ribs using pipe screws; install tension screws on the top of the inner and outer formwork of the exterior wall, and install diagonal braces at the bottom; S6. Concrete pouring: pour the exterior wall concrete in layers and sections; S7. Removal of inner and outer formwork of exterior wall: After the exterior wall concrete reaches the required strength, the inner and outer formwork of the exterior wall will be removed and transferred to other floors for use.

[0006] Preferably, in S1, the exterior wall concrete texture is 0-50 mm triangular prisms protruding from the wall surface, with 100 mm wide and 50 mm thick grooves between adjacent triangular prisms, and the orientations of adjacent triangular prisms are inconsistent.
