Built-in stand type cast-in-place reinforced concrete pillar and construction method

Abstract

The invention provides a built-in stand type cast-in-place reinforced concrete pillar which comprises a concrete pillar body and main ribs arranged in the concrete pillar body. The periphery of the concrete pillar body is provided with built-in stands at intervals in the height direction. The built-in stands comprise supporting rods connected with the main ribs and four stand rods connected with the other ends of the supporting rods. The stand rods are parallel to the corresponding concrete pillar body side faces. The adjacent stand rods are connected through corner connectors at the ends. The exterior of the stand rods of the built-in stand is provided with a formwork. The built-in stand type cast-in-place reinforced concrete pillar is reasonable in structure and simple in step. When the built-in stand type cast-in-place reinforced concrete pillar is mounted, as long as the situation that the outer side faces of the stand rods and the corner connectors flush with the exterior and the corner of the pillar is guaranteed, additional alignment of the formwork and adjustment and correction of the perpendicularity of the formwork are not needed in the mounting process, the requirement for the technological level of personnel who mount the formwork on site is low, construction efficiency can be greatly improved, mounting accuracy is easy to control, construction quality can be improved, and the working difficulty of formwork mounting is lowered.

Description

technical field [0001] The invention belongs to the technical field of building structures, and in particular relates to a built-in support type cast-in-place reinforced concrete column and a construction method. Background technique [0002] At present, in the field of construction engineering, it is a common choice to use bamboo plywood as the formwork of cast-in-place structural components. Its appearance is good and it is highly praised by users. [0003] In the construction process of the construction project, the positioning alignment and verticality control of the bamboo plywood is a very important technology, which directly affects the construction quality of the process and the appearance quality of the concrete pouring. [0004] However, the general installation method of the formwork of the existing cast-in-place reinforced concrete columns is: foundation spring line→formwork in place→position correction→temporary fixation→perpendicularity adjustment→check and acc...

Problems solved by technology

[0004] However, the general installation method of the formwork of the existing cast-in-place reinforced concrete columns is: foundation spring line→formwork in place→position correction→temporary fixation→perpendicularity adjustment→check and acceptance→formwork fixing. The problem with this method is: The carpenter responsible for the assembly has high technical requirements, high labor intensity, difficult quality control, poor working environment and complicated operation procedures, which make the construction efficiency too low
