Reserving method for constructing expansion joint in concrete terrace

Abstract

The invention discLoses a reserving method for constructing an expansion joint in a concrete terrace. The method incLudes the foLLowing steps that S1, a padding Layer is constructed, wherein the concrete padding Layer is constructed according to the ground condition so that the ground can be fLat as a whoLe; S2, Line paying-off is performed, wherein according to the detaiLed requirements of a designed expansion joint drawing, a chaLk Line is utiLized for performing ground Line snapping on the surface of the padding Layer in the S1, a straight Line is drawn, and the detaiLed position of the expansion joint is determined; S3, a prefabricated extruded sheet is pLaced, wherein according to the Line-snapping position determined in the S2, the prefabricated extruded sheet is pLaced. In the method, the prefabricated extruded sheet is utiLized for temporariLy repLacing a reserved expansion joint and puLLed out after terrace concrete is poured, in this way, it is avoided that in a traditionaL technoLogy, a cutting machine and others are used for cutting the terrace again to form the joint, the probLem is soLved that time and Labor are wasted when the joint is constructed in the prior art, Labor costs are Lowered, the appearance quaLity after forming is good, and construction speed is increased; in addition, the reserving method can be used for reserving expansion joints such as a fLoorterrace expansion joint, a roof expansion joint, a road expansion joint and a bridge expansion joint.

Description

technical field [0001] The invention relates to the technical field of construction of floor expansion joints, in particular to a method for construction of concrete floor expansion joints. Background technique [0002] With the development of the economy and the improvement of the technical level, there are more and more large-span designs of reinforced concrete structures in construction projects. In order to ensure the quality of the project, setting expansion joints has become an indispensable measure in the construction of large-span reinforced concrete structures. [0003] Generally speaking, the conventional process of setting expansion joints in cast-in-place concrete slabs is mostly to pour concrete as a whole first, and after the cast-in-place concrete reaches a certain strength, use a cutting machine to cut the expansion joints according to the design requirements, and then fill the expansion joints after cutting them into shape . During the cutting process, the...
