Description
Technical Field
The invention relates to a permanent template and a method for pouring a shear wall by adopting the permanent template, belonging to the field of shear wall construction.
Background
With the rapid development of high-rise buildings in China, reinforced concrete shear wall structures are applied to buildings more and more. Shear wall structures have become one of the main structural forms of buildings in China. Although the shear wall structure is widely used, certain defects still exist in the construction and forming process of the wall body.
The forming construction of present shear force wall mainly includes: the method comprises three modes of cast-in-place integral forming, prefabricated assembly splicing and laminated plate type shear wall. The cast-in-place integral forming needs to use a template to obtain a concrete member with a designed shape, a large number of templates need to be installed before the shear wall is poured, and the template can be detached only after the concrete reaches the strength. The whole template worker installs and removes the template and wastes time and energy, and the die assembling and disassembling processes not only seriously restrict the construction progress, but also further increase the construction cost. With the national vigorous popularization of prefabricated building industrialization, the assembled integral shear wall is developed. But the assembled building has the problems of infirm assembled parts, poor integrity and seismic performance and the like, and the assembled integral shear wall has large volume and weight, low transportation efficiency and fussy assembly, and has no advantages in cost and construction period compared with the traditional cast-in-place molding.
For a laminated plate type shear wall structure (double-skin wall), two concrete wallboards are combined in a pulling mode through a steel bar truss, and a die with a cavity is formed in a factory in a prefabricated mode. And (3) placing concrete in the cavity after field installation and positioning, thereby forming the prefabricated and cast-in-place concrete integrally stressed wall. However, in the prefabrication process of the laminated plate type shear wall, a steel bar truss needs to be bound and arranged in the concrete wall plate, and only when one wall plate reaches the strength, the other wall plate can be poured in a turnover mode. The whole manufacturing process is complicated and complicated, and the prefabrication efficiency is low. In addition, when the wall is constructed and assembled, the distributed reinforcing steel bars in the wall board are not connected up and down, so that the stress performance and the overall performance of the wall board are weaker than those of a cast-in-place wall body. The mode has more cast-in-place and prefabrication, the working procedures are not reduced, and the construction cost is increased.

(1) the formwork-free pouring of the shear wall is realized, the construction procedure is simplified, and the construction efficiency is improved
The permanent formwork is adopted to cast the integral forming mode of the shear wall, the permanent formwork does not need to be dismantled after the casting is finished, and the permanent formwork is used as a part of an integral structure, so that the supporting and forming functions of the cast concrete are met, the permanent formwork can become a reserved part of a building structure, the building structure participates in the bearing of a building, and the stress performance and the service performance of the structure are improved. Therefore, the time and cost consumed by removing the formwork and transporting the formwork can be greatly saved, the construction period is greatly shortened, the construction cost is reduced, and the construction efficiency is improved.
(2) The concrete sheets forming the permanent formwork are prefabricated separately, the manufacture is simple and the forming rate is high
The two concrete sheets in the permanent template are prefabricated separately, and the connecting buckles are embedded independently when the reinforcement cage is bound, so that the permanent template can be assembled and used like combined furniture. Thereby avoided the whole shaping of pouring, the preparation procedure is simple, has improved the shaping rate of prefabrication efficiency and template to a great extent, has stronger maneuverability and application.
(3) The reinforcing steel bars in the shear wall are continuous and uninterrupted, and the integral stress performance is good
By adopting the integral cast-in-place molding mode, the stressed reinforcing steel bars in the wall body are continuous, the integrity and the continuity of the wall body are good, and therefore, the integral stress performance is good.
