Method for assembling prefabricated part reinforcing column through concrete

Abstract

The invention provides a method for assembling a prefabricated part reinforcing column through concrete. The method comprises the steps that a painting layer or a cushion layer on the surface of a component is chiseled away to a concrete base layer for treatment; the surface of the base layer and the surface of a concrete prefabricated part are coated with adhesives; the concrete prefabricated part is fixed; the concrete prefabricated part is clamped with a clamp, and is properly pressurized; impurities in a hole channel are removed, a prestressed steel strand is manually pulled, and the steel strand is tensioned and fixed; pipeline grouting and anchor sealing are conducted; and after the adhesive is cured, the clamp is dismantled. Vertical steel bars of the concrete prefabricated parts are connected through a sleeve grouting technology, and fine aggregate concrete or grouting materials are poured at connecting positions of the prefabricated parts and anchor sealing positions for sealing treatment. According to the method, a fabricated concrete column and brick column reinforcing method is provided, the method is good in corrosion resistance and fire resistance, saves energy and is environmentally friendly, the method can effectively improve the mechanical property of the concrete column, the reinforcing effect is guaranteed, standardized fabricated parts are adopted in the construction process, on-site wet operation is greatly reduced, the labor consumption is reduced, the construction efficiency is improved, the cost is reduced, and the construction period is shortened.

Description

technical field [0001] The invention belongs to the technical field of construction; in particular, it relates to a method for reinforcing columns by assembling prefabricated parts with concrete. Background technique [0002] In the process of building construction and use, due to many problems such as unreasonable structural design, construction quality control level and management errors, natural disasters, and changes in use functions, the column components in the building must be reinforced to meet the design or use requirements. . [0003] At present, common reinforcement methods include: enlarging section method, pasting steel plate method, outsourcing section steel method, pasting carbon fiber composite material, replacing concrete method, etc. Among them, the column is generally strengthened by enlarging section method and outsourcing steel method. But above existing reinforcement method also has the following deficiencies: [0004] (1) The increased cross-section...

AI Technical Summary

Problems solved by technology

[0004] (1) The increased cross-section method has a large workload of wet work on site, a long maintenance time, a long construction period and the need to bind steel bars and use a large number of formwork during the reinforcement process. After the maintenance is completed, the formwork needs to be removed, and the construction process needs to be chiseled. There is some damage to the original components, and the labor, material and time costs are high

[0005] (2) The amount of steel used in the outsourcing steel method is large, the reinforcement cost is high, and welding is required on site, and the fire resistance is poor

[0006] (3) The method of pasting steel plates cannot fundamentally solve problems such as concrete defects, and the amount of steel used is large, and the requirements for adhesives are high

[0008] (5) The construction process of the replacement concrete method is complicated, there is a certain amount of wet work, the curing time is long, and the defective concrete needs to be manually removed, which is easy to cause certain damage to the steel bars

[0010] In recent years, many colleagues in the industry have improved the traditional reinforcement method and applied for various types of patents, but there is no report on a convenient and effective reinforcement method that can reduce on-site wet work or reduce the difficulty of construction technology and speed up the construction progress.
