Embodiment Construction

[0020] The present invention is further illustrated below by specific examples.

[0021] A construction method for reducing deviations in the thickness of concrete slabs, comprising

[0022] Step 1, prepare plastic mold tube;

[0023] Step 1.1, process several sections of plastic mold tubes of the same height according to the thickness of the designed concrete slab;

[0024] Step 1.2, cutting the plastic mold tube described in step 1.1 into two pieces from the axial direction;

[0025] Step 1.3, tighten the plastic mold tube described in step 1.2 with cable ties to restore it to a whole;

[0026] Step 2, preparing the elevation reference column;

[0027] Step 2.1, brushing a release agent on the inner wall of the plastic mold tube described in step 1.3;

[0028] Step 2.2, pouring cement mortar grade not less than po42.5 into the plastic mold tube and vibrating and compacting;

[0029] Step 2.3. Insert an iron nail into the bottom of the cement mortar before the initial se...

Abstract

The invention relates to the field of concrete pouring in building construction, in particular to a construction method for reducing the thickness deviation of concrete slabs; it is characterized in that it includes step 1, preparing plastic mold tubes; step 2, preparing elevation reference columns; and step 3, carrying out concrete slab Step 4, fix the elevation reference column on the bottom formwork of the concrete slab; Step 5, pour the floor concrete, and take the horizontal line grid as described in step 4 as the height standard during troweling, so as to ensure that the poured concrete slab surface The thickness deviation is within the allowable range. The construction method adopts the above steps, wherein the processing materials of the plastic mold pipe are easy to obtain and simple to manufacture; the accuracy of the thickness of the concrete slab in one construction can be effectively improved so as to improve the pouring precision. The concrete elevation reference column is fixed on the formwork by nails, which is not easy to be kicked, stepped on, or misplaced by the operator; after the work is completed, molds such as plastic mold pipes can be recycled repeatedly.

Description

technical field [0001] The invention relates to the field of concrete pouring in building construction, in particular to a construction method for reducing thickness deviation of concrete slabs. Background technique [0002] In construction engineering, especially in housing construction, the construction of concrete floors and floors by conventional methods has the problems of large thickness accuracy deviation and difficult control of flatness; especially in the construction of large flat-storey shopping malls and squares, the accuracy of flatness control The requirements are stricter. Contents of the invention [0003] The object of the present invention is to provide a construction method capable of reducing thickness deviation of concrete slabs during construction. [0004] In order to achieve the above object, the present invention is achieved in that: [0005] A construction method for reducing deviations in the thickness of concrete slabs, comprising [0006] St...
