Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a construction method of an assembled wall. Background Art

[0002] In the construction industry, prefabricated walls are widely used due to their advantages such as high efficiency and convenience. However, in the construction and installation of existing prefabricated walls, the excessive weight of the prefabricated walls greatly increases the difficulty of construction. First of all, large-scale, high-performance lifting equipment is required to complete the lifting and installation operations, which not only increases the rental cost of construction equipment, but also has high requirements for the site conditions of the construction site. It is necessary to ensure that the site can withstand the weight of the lifting equipment and the operating load. Secondly, during the installation process, due to the heavy weight of the wall, the control of the installation accuracy is more difficult. Once a deviation occurs, it is extremely difficult to adjust, which may affect the connection quality between the walls and endanger the stability of the entire building structure. Moreover, when installing an overweight prefabricated wall, higher operating skills and physical strength are required of the construction workers, which increases the labor intensity and safety risks of the construction workers. Therefore, there is an urgent need for a prefabricated wall construction method that can effectively solve the above problems. Summary of the invention

[0003] The present invention aims to solve the above-mentioned problem, thereby providing a construction method of an assembled wall.

[0004] The present invention solves the above-mentioned problem by adopting the following technical solution: A construction method for an assembled wall comprises the following steps: S1. Prefabricated component production: two thin wall panels are produced, opposite tension bolt holes are reserved around the two thin wall panels, and tension screws are produced at the same time; S2. On-site installation preparation: After the prefabricated wall is transported to the construction site, the steel mesh of the building is inspected and cleaned to ensure that the position and specifications of the steel mesh meet the design requirements and there is no debris on the surface; S3, installation of thin wall panels: the two thin wall panels made in step 1 are installed on both sides of the building steel mesh respectively, so that the tension bolt holes on the thin wall panels correspond to the positions of the steel mesh, and the tension rods are passed through the tension bolt holes to preliminarily fix the two thin wall panels; S4, Adjustment and reinforcement: Use measuring tools to measure the verticality and flatness of the installed thin wall panels, and fine-tune the position of the thin wall panels according to the measurement results to ensure that the installation accuracy meets the requirements, and then tighten all the lead screws to complete the reinforcement of the thin wall panels; S5. Casting and molding: After completing the reinforcement of the thin wall panels, pour lightweight concrete between the two thin wall panels and vibrate to make them dense. After the lightweight concrete reaches the designed strength, the construction of the prefabricated wall is completed.

[0005] Furthermore, in S1, when manufacturing the thin wall panels, connecting steel bars are embedded in the thin wall panels, and the connecting steel bars are used to enhance the connection strength between the thin wall panels and the lightweight concrete.

[0006] Furthermore, in S2, when inspecting the building steel mesh, the spacing between the steel bars is detected, and if the detection result does not meet the design requirements, the steel mesh is adjusted.

[0007] Furthermore, in S4, when adjusting the thin wall panel, an adjustable support member is used to temporarily support the thin wall panel to assist in adjusting and fixing the position of the thin wall panel.

[0008] Compared with the prior art, the present invention adopting the above technical solution has the following outstanding features: The present invention greatly reduces the weight of components by designing the assembled wall to be composed of two thin wall panels and lightweight concrete poured in the middle. During transportation, the requirements for transportation vehicles and road conditions are reduced, the purchase and maintenance costs of transportation equipment are reduced, the transportation efficiency is improved, and the number of transportations and time costs are reduced. In the construction and installation process, due to the reduced weight of the components, the requirements for lifting equipment and construction site conditions are reduced, the rental cost of construction equipment is reduced, and the difficulty of installation precision control is reduced, the installation quality and construction efficiency are improved, and the labor intensity and safety risks of construction personnel are reduced.

DETAILED DESCRIPTION

[0010] The present invention will be further described below in conjunction with embodiments, the purpose of which is only to provide a better understanding of the content of the present invention. Therefore, the examples given do not limit the protection scope of the present invention.

[0011] See also Figure 1-Figure 2 , a construction method of an assembled wall, comprising the following steps: S1. Prefabricated component production: In the prefabrication factory, two thin wall panels 1 are produced according to the design requirements, using appropriate molds and materials to ensure that the size and shape of the thin wall panels 1 meet the standards. In the process of producing the thin wall panels 1, opposite tension bolt holes 4 are reserved around the thin wall panels 1, and tension screws 3 matching the tension bolt holes 4 are produced. In addition, connecting steel bars are embedded in the thin wall panels 1, and the specifications and quantity of the connecting steel bars are determined according to the design requirements to enhance the connection strength between the thin wall panels 1 and the subsequently poured lightweight concrete.

[0012] S2. On-site installation preparation: After the prefabricated wall is transported to the construction site, arrange professionals to inspect and clean the steel mesh 2 of the building. Check whether the position and specifications of the steel mesh 2 are consistent with the design drawings, and check whether the steel mesh 2 is deformed or rusted. If there are any problems, deal with them in time. Clean the sundries and oil stains on the surface of the steel mesh 2 to ensure that the surface of the steel mesh is clean and tidy, so as to prepare for the subsequent installation of thin wall panels.

[0013] S3. Installation of thin wall panels: Install the two prefabricated thin wall panels 1 on both sides of the building steel mesh 2, respectively, so that the tension bolt holes 4 on the thin wall panels 1 correspond to the positions of the steel mesh. Pass the tension screws 3 through the tension bolt holes 4 to preliminarily fix the two thin wall panels 1 to ensure that the thin wall panels 1 will not shift during the installation process. During the installation process, pay attention to the installation direction and position of the thin wall panels to ensure the accuracy of the installation.

[0014] S4, Adjustment and reinforcement: Use measuring tools such as a level and theodolite to measure the verticality and flatness of the installed thin wall panel 1. According to the measurement results, use adjustable supports to temporarily support the thin wall panel 1, such as triangular wedges, etc. By adjusting the position and angle of the supports, fine-tune the position of the thin wall panel 1 so that the verticality and flatness of the thin wall panel 1 meet the design requirements. After the adjustment is completed, tighten all the wire drawing rods 3 to ensure that the thin wall panel 1 is firmly fixed on the steel mesh 2, and the reinforcement of the thin wall panel 1 is completed.

[0015] S5. Casting and forming: After the thin wall panels 1 are reinforced, lightweight concrete is poured between the two thin wall panels 1 and vibrated to make them dense. After the lightweight concrete reaches the designed strength, the construction of the prefabricated wall is completed.

[0016] The present invention greatly reduces the weight of components by designing the assembled wall to be composed of two thin wall panels and lightweight concrete poured in the middle. During transportation, the requirements for transportation vehicles and road conditions are reduced, the purchase and maintenance costs of transportation equipment are reduced, the transportation efficiency is improved, and the number of transportations and time costs are reduced. In the construction and installation process, due to the reduced weight of the components, the requirements for lifting equipment and construction site conditions are reduced, the rental cost of construction equipment is reduced, and the difficulty of installation precision control is reduced, the installation quality and construction efficiency are improved, and the labor intensity and safety risks of construction personnel are reduced.
