Problems solved by technology

[0003] At present, most floor construction methods still use laser leveling machines and manual leveling. However, due to the lack of a systematic method, the control of the flatness of the concrete floor is poor, and the efficiency of the construction method is low. There are many split joints, warehouse jumping construction, many human factors, and the control accuracy of the flatness of the building floor often fails to meet the design requirements

Embodiment Construction

[0026] In order to better understand the present invention, the present invention will be further described below in conjunction with specific examples.

[0027] A ground construction method for a high-precision building with controllable flatness, comprising the following steps:

[0028] Step 1. Construction preparation, layout of sub-storage joints and cutting joints;

[0029] Step 2. Measure and set control points, and use the method of closed wires to conduct secondary closed measurement of all control points on the ground of the floor with the level instrument on the basis of the primary closure of the engineering reference point, so as to ensure the accuracy of all control points on the ground of the floor. The elevation is on the same level;

[0030] Step 3, formwork and reinforcement construction, and check the formwork;

[0031] Step four, pouring concrete;

[0032] Step 5. Treatment of the concrete floor, including extracting slurry, spreading wear-resistant aggre...

Abstract

The invention discloses a flatness controllable high precision floor construction method which comprises the following steps: construction preparation and arrangement of points warehouse seams and kerfs; laying off of control points, and secondary closed measurement of all control points of a floor, wherein elevations of all the control points of the floor are in a same horizontal plane; templateand reinforcing steel bar construction and checking of templates; concrete pouring; treatment of a concrete ground; concrete curing; and floor protection. The flatness controllable high precision floor construction method has the beneficial effects that the flatness controllable high precision floor construction method is high in effect and good in quality; the points warehouse seams are reduced;the integrity of the ground is better; alternation of follow-up work is facilitated; and the follow-up maintenance cost of the floor can be reduced.

Description

technical field [0001] The invention relates to the technical field of flatness detection, in particular to a ground construction method of a high-precision building with controllable flatness. Background technique [0002] For logistics and warehousing workshops, due to their functional characteristics, the requirements for the accuracy of the building ground are relatively high, and the flatness requirements generally do not exceed 3mm / 2m, and the range does not exceed 20mm. Logistics and warehousing workshops have a large area, require high surface smoothness, have special treatment for the surface, and require one-time survival. High-precision control of the flatness of concrete building floors has always been a difficult point in floor construction. [0003] At present, most floor construction methods still use laser leveling machines and manual leveling. However, due to the lack of a systematic method, the control of the flatness of the concrete floor is poor, and the...
