Prefabricated vertical member

Abstract

The invention provides a prefabricated vertical member (including a pillar and a wall), which mainly comprises a member body and a prefabricated reinforcing bar (the reinforcing bar is the joint name of a principle bar longitudinally arranged along the member body, a vertically-distributed reinforcing bar, a hooping and a tie bar), and the principle bar or the principle bar and the vertically-distributed reinforcing bar stretch out of the upper end surface and the lower end surface of the member body. The prefabricated vertical member is characterized in that a core column is arranged in the middle of the lower end surface of the member body. The invention has the advantages that the installation of the prefabricated vertical member has no conflict with the anchoring of beam steel at a support, so as to meet the code requirement of the structure of cast-in-situ reinforced concrete; the core column is adopted for bearing load, the upper-layer construction operation can be carried out when in the joint concreting; no special design is needed; the connection of the reinforcing bar and the binding of a template are carried out at a floor slab, thereby not only ensuring the safety of workers, but also obviously improving the construction efficiency and the construction quality; the quantity of overhead work can be greatly decreased; the quantity of cast-in-situ concrete can be greatly decreased; and the operation is carried out at the floor slab, therefore, the construction speed is greatly improved.

Description

technical field [0001] The invention relates to building elements, prefabricated vertical elements - columns and walls. Background technique [0002] With the acceleration of China's urbanization process, the society's demand for high-rise residences is becoming increasingly urgent. Traditional buildings are constructed on site (including steel bar binding, formwork support, concrete pouring, etc.). The technical level is uneven, and the amount of high-altitude operations is large, and there are problems such as large consumption of formwork and support materials, low construction efficiency, long construction period, and difficult control of project quality. However, the existing prefabricated component construction methods and joint treatment at home and abroad can only meet the requirements of the precast concrete specification, but not the requirements of the Chinese cast-in-place reinforced concrete specification. Therefore, technical exploration is being carried out on...

Problems solved by technology

[0002] With the acceleration of China's urbanization process, the society's demand for high-rise residences is becoming increasingly urgent. Traditional buildings are constructed on site (including steel bar binding, formwork support, concrete pouring, etc.). The technical level is uneven, and the amount of high-altitude operations is large. There are problems such as large consumption of formwork and support materials, low construction efficiency, long construction period, and difficult control of project quality.

However, the existing prefabricated component construction methods and joint treatment at home and abroad can only meet the requirements of the precast concrete specification, but not the requirements of the Chinese cast-in-place reinforced concrete specification. Therefore, technical exploration is being carried out on issues such as the design of prefabricated components and the installation of joint treatment.
