Description

Technical Field

[0001] The invention belongs to the field of shear walls, and in particular relates to an assembled fireproof, heat-insulating, load-bearing integrated shear wall and a construction method thereof. Background Art

[0002] With the continuous deepening of the process of building industrialization, the construction industry is undergoing a profound transformation from traditional construction mode to modernization, efficiency and environmental protection. In this context, the traditional construction mode has gradually shown many limitations in the face of the diversified demands of modern construction projects for high efficiency, high quality, multi-function and environmental protection. In particular, the traditional cast-in-place shear wall system, although it ensures the integrity and stability of the building structure to a certain extent, has inherent problems such as long construction period, difficulty in quality inspection, high resource consumption and significant environmental impact, which have become an important bottleneck restricting the sustainable development of the construction industry.

[0003] As a widely used structural form in the current construction field, the construction process of cast-in-place shear wall system is cumbersome and complicated, involving a large amount of manual operation and on-site wet work. This not only leads to the extension of the construction period and increases the construction cost, but also brings many uncertainties and quality control difficulties in the construction process. Especially in large-scale construction projects such as high-rise residential buildings, commercial complexes and public facilities, the construction difficulty and quality control problems of cast-in-place shear wall system are particularly prominent, which seriously affects the overall progress and quality of the construction project.

[0004] In addition, the design and application of cast-in-place shear wall systems mainly focus on their wind resistance, earthquake resistance and static bearing performance, while ignoring the demand for multifunctional building materials in modern society. With the rapid development of science and technology and the continuous improvement of people's living standards, the functional requirements for shear walls in the construction field are becoming increasingly diversified. The traditional single load-bearing function can no longer meet the needs of modern buildings for fire prevention, heat preservation, thermal insulation and other aspects. Especially in high-rise residential buildings, commercial complexes and public facilities, higher requirements are placed on the comprehensive performance of shear walls, requiring shear walls to not only have excellent bearing performance, but also have diversified functions such as fire prevention, heat preservation and thermal insulation to improve the comfort and safety of buildings.

[0005] However, most of the shear wall products on the market are still at the stage of single function or simple combination, lacking a comprehensive solution that integrates fire prevention, heat preservation, thermal insulation, assembly and rapid construction. These products still have many deficiencies in construction efficiency, quality control, functional diversity and environmental performance, and cannot meet the diversified needs of modern buildings for high efficiency, high quality, multi-function and environmental protection.

[0019] A construction method of an assembled fireproof heat-insulating load-bearing integrated shear wall, used to construct the above-mentioned assembled fireproof heat-insulating load-bearing integrated shear wall, comprises the following steps:

[0020] S1, bottom layer assembly:

[0021] According to the design drawings, connect the bottom template and bottom corner template in sequence, and ensure the tightness of the connection between adjacent templates;

[0022] S2, standard layer assembly:

[0023] The standard layer formwork and the standard layer corner formwork are sequentially assembled on the upper part of the bottom layer formwork and the bottom layer corner formwork. The length of the standard layer formwork is flexibly cut according to the construction situation, so that the upper and lower adjacent standard layer formworks are stacked in a staggered manner to ensure the casting quality and aesthetics of the shear wall;

[0024] S3, top level assembly:

[0025] After the standard layer is assembled to the designed height, the top layer formwork and the top layer corner formwork are assembled to the topmost standard layer formwork and the standard layer corner formwork as required; in addition, in order to ensure the stability of the shear wall, the card strip adopts a dovetail structure or a T-shaped structure, the card slot adopts a dovetail slot or a T-shaped slot, and the standard layer formwork and the bottom layer formwork, the standard layers and the standard layers, and the standard layer and the top layer formwork are assembled in a push-pull manner;

The reinforcement laying runs through the whole process of the shear wall template construction. During the shear wall template construction, the transverse reinforcement is placed at the corresponding position according to the design requirements of the reinforcement laying height.

[0030] S6, concrete pouring:

[0031] Before pouring concrete, a top support structure is built under the door and window upper formwork to prevent deformation or even damage to the door and window upper formwork during concrete pouring. During concrete pouring, each layer of formwork and the blocking plate serve as the formwork for concrete pouring, which improves the efficiency of shear wall construction.

[0034] The beneficial effects of the present invention are:

[0035] 1) The shear wall of the present invention is quickly assembled using various templates, and the various templates are not only used as templates for pouring shear wall concrete, but also have a heat preservation function. After the shear wall is poured, fire retardant coating is sprayed on the outside of the template, which also realizes the fire prevention function of the shear wall.

[0036] 2) By setting door and window templates and blocking plates, the need to open doors and windows on the shear wall is solved, further expanding and extending the function of the prefabricated shear wall.

[0037] 3) The connector is designed to be an H-shaped structure with a thin middle and thick ends, which expands the contact area when the connector is connected to the base plate or the corner plate, thereby ensuring the strength and stability of the connection between the connector and the base plate or the corner plate.

[0038] 4) Limiting grooves for positioning transverse reinforcement are set on the connecting parts to ensure the accuracy of the placement of transverse steel parts, which not only helps to achieve the standardization and modular construction of shear wall structures, but also helps to form a uniformly distributed steel grid, enhance the overall stiffness and seismic performance of the structure, and improve the stability and safety of the overall structure.

[0039] 5) The card strip adopts a dovetail structure or a T-shaped structure, the card slot adopts a dovetail slot or a T-shaped slot, and the shear wall is assembled in the form of left and right push-pull. The corresponding card strips and card slots with an assembly relationship have an interference fit, which ensures the tightness of the connection between various templates and enhances the thermal insulation effect of the shear wall.
