Embodiment Construction

[0043] Examples see figure 1 As shown, a construction method of a large-area concrete floor, the construction steps are as follows:

[0044] Step 1: Divide the construction flow section and the location of the construction separation joint. According to the on-site construction deployment, the foundation floor and the structural roof of the construction area are divided into flow sections respectively. According to the division of flow sections, the pouring area of ​​the foundation floor and foundation roof is calculated.

[0045] The flatness detector for testing the flatness plans the measurement line according to the boundary of the flow section. All the measurement lines are parallel straight lines and perpendicular to the longest flow section boundary. The measurement lines are divided into north-south measurement lines and east-west measurement lines. The measurement lines are at least The length is 3.3528m, the measuring line is 1.2192m shorter than the length and width o...

Abstract

The invention discloses a construction method for a large-area concrete weighbridge. The construction method comprises the steps of: dividing the locations of a construction water flowing section and a construction separation joint, erecting a weighbridge side template, installing a force transmission rod at a junction of the water flowing section, erecting a laser leveller, fixing a levelling staff, selecting a levelling base point, pouring concrete in a space surrounded by weighbridge templates, vibrating, compacting and levelling the weighbridge by the leveller, finishing surface conditioning and polishing of the concrete weighbridge before the final solidification of the concrete, maintaining the concrete weighbridge, cutting the construction separation joint within 24h, stuffing the construction separation joint and carrying out secondary maintenance. By the construction method, the technical problem that the whole levelling degree of the large-area weighbridge is very difficult to control is solved; the problems that the cost of later maintenance of the ground and the use quantity of the templates are very high since the construction joint of the large-area concrete weighbridge is very prone to breakage is solved; and the problems such as breakage along a warehouse dividing joint on the large-area concrete weighbridge, easy hollowing in the layered pouring of the weighbridge, easy cracking and the like are solved.

Description

technical field [0001] The invention relates to a construction method for a large-area concrete floor. Background technique [0002] The traditional method of large-area concrete floor construction is to use simple rulers and feeler plugs to check the flatness with a ruler. The traditional method can only check parts and cannot reflect the overall flatness of large-area floors. It is difficult to improve the concrete. The construction quality of the floor. Large-area concrete floors are subjected to wheel loads during construction, and construction joints are prone to damage, which greatly increases the later maintenance costs of the ground and the use of formwork. Due to maintenance and formwork support, the joints of the warehouses on the large-area concrete floor will have defects such as damage along the joints, and the layered pouring of the floor will also cause problems such as easy hollowing and cracking. Contents of the invention [0003] The purpose of the pres...
