High-quality precast beam production method of embedded steel plate for precise positioning curtain wall installation

Abstract

The invention discloses a high-quality precast beam production method of an embedded steel plate for precise positioning curtain wall installation. The high-quality precast beam production method of the embedded steel plate for precise positioning curtain wall installation comprises a mould table for building a mould, a rear-side mould plate, a front-side mould plate and two end mould plates, wherein multiple upper rows of through holes and multiple lower rows of through holes are formed in the front-side mould plate; a fixator is arranged on the front-side mould plate; and after the fixator is installed, the end face of a magnetic drawing end of a magnetic base and the end face of an end cover are parallel and level to the inner surface of the front-side mould plate. A preparation processcomprises the following steps of (1) detecting the mould plates; (2) assembling the rear-side mould plate, assembling the embedded steel plate, binding a reinforcement cage, and arranging a support fork in the reinforcement cage; (3) hoisting the reinforcement cage; (4) installing the front-side template plate; (5) assembling the end mould plates; (6) inspecting the assembling quality; (7) concreting; (8) disassembling the mould; and (9) polishing beam corners. According to the high-quality precast beam production method of the embedded steel plate for precise positioning curtain wall installation provided by the invention, the position of the embedded steel plate can be precisely positioned, and the thickness of an upper-row reinforcement protection layer is effectively controlled.

Description

technical field [0001] The invention relates to the technical field of preparation of prefabricated components, in particular to a production method of high-quality prefabricated beams for precisely positioning pre-embedded steel plates for curtain wall installation. Background technique [0002] PC components have many advantages such as high efficiency and energy saving, green environmental protection, cost reduction, and providing functions. In recent years, various new construction concepts such as construction industrialization, energy saving and emission reduction, quality safety, and ecological environmental protection have brought development opportunities for PC components. In the process of urbanization, a large number of infrastructure constructions, large-scale affordable housing urgently need standardization, rapid construction and high Quality construction provides a wide space for PC components. [0003] Since PC components are all prefabricated structures, t...

Problems solved by technology

However, since the main reinforcement on the top surface of the prefabricated beam is only fixed at both ends and assisted by the hoop hoop, the actual situation cannot prevent the serious downward deflection problem in the middle of the main reinforcement caused by heavy gravity, and the maximum deviation on site can reach 10mm-20mm , resulting in a seriously large steel protection layer on the top surface of the prefabricated beam after pouring and forming, which may directly lead to failure of component inspection and acceptance, and bring huge losses to the prefabricated component factory

[0007] 3. Due to the lack of good control methods, the deviation of prefabricated beam cross-section size exceeds the standard from time to time
