Problems solved by technology

[0002] High-grade concrete has strong fluidity and large slump. The low-grade slump is 12 cm, and the high-grade slump is 16 cm. Therefore, high-grade concrete is easy to seep out in the formwork gap during pouring, and then honeycomb, hemp Common quality defects such as surface and exposed ribs make the strength of the column not reach the expected strength

Embodiment Construction

[0039] The present invention will be further described below in conjunction with accompanying drawing of description, but protection scope of the present invention is not limited thereto:

[0040] The construction process of a high-grade concrete column foot of the present invention includes the following steps: binding steel bars→pillar formwork→setting a slurry stop bar→installing isolated steel mesh pieces→concrete pouring and tamping for a primary vibration→concrete pouring and tamping for a second vibration→ After pouring, maintenance and repair → remove the column formwork. If the pouring column is an outer column, after the column formwork and before setting the grout stop strip, the bolts are pre-embedded. Before the side column concrete is poured, pre-embed tie bolts at 100-200mm below the level of the top surface of the floor slab. When preparing the formwork, extend the lower part of the formwork at this position by 300-400mm. When setting up the formwork, fix the lo...

Abstract

The invention provides a construction technology for a high-grade concrete column base, and belongs to the technical field of building construction. The construction technology comprises the following steps of steel bar binding, column formwork installing, paste stop strip arranging, isolation steel bar mesh installing, first-time vibrating of concrete pouring and tamping, secondary vibrating of concrete pouring and tamping, curing and finishing after pouring and column formwork dismantling. The construction quality problems of the high-grade concrete column base are successfully solved, the quality problems such as column honeycombs, pitted surfaces and steel bar exposure are solved, the concrete column quality is improved, the quality passing percent of the concrete column base obtained by the method is improved from the present 85 percents to more than 95 percents, the economic benefits are generated, the economy consciousness of all workers is improved, the enterprise popularity is improved while the construction cost is reduced and the construction quality is improved, and the competitive power of the building market is enhanced.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a construction process for high-grade concrete column feet with good construction quality, high economic benefits and low construction cost. Background technique [0002] High-grade concrete has strong fluidity and large slump. The low-grade slump is 12 cm, and the high-grade slump is 16 cm. Therefore, high-grade concrete is easy to seep out in the formwork gap during pouring, and then honeycomb, hemp Common quality defects such as surface and exposed ribs make the strength of the column not reach the expected strength. Contents of the invention [0003] In view of the above-mentioned problems existing in the prior art, the purpose of the present invention is to provide a construction process of high-grade concrete column feet with good construction quality, high economic benefits, low construction cost and suitable for market competition. [0004] Th...
