Embodiment 1

[0019] The construction technology of large concrete slabs in storage yard is characterized in that it includes the following operation steps:

[0020] (1) During formwork processing, the upper top surface of the panel is 5mm higher than the upper transverse rib, and the upper transverse rib is used as a groove, and the upper transverse rib and the panel are welded at the groove;

[0021] (2) The formwork is supported by a tensioner group, each tensioner group includes two tensioners, one end of the two tensioners is hinged on the anchor, the anchor includes a sleeve and a bolt, and the sleeve is fixed on the steel braze Above, instead of using wooden wedges for anchoring, bolts are used for anchoring. The steel drill is nailed into the foundation through the casing. The other ends of the two tensioners are respectively hinged with the formwork. The two tensioners and the steel drill form a "K" shape. After the surveyor re-measures the formwork, the insufficient elevation shal...

Abstract

The invention discloses concrete slab construction process in a storage yard. Through concrete slab construction process in the storage yard, a host of process improvements can be made on manufacture and erection of a template, concrete control, installation of drive rods and processing of slab slits such that the template is convenient and rapid to erect and dismount and vertical inclination and straightness of the temperature can be flexibly regulated. The template is firmly fixed and has good pulp-checking effect. The drive rods are accurate in positions and straightened. The top surface of the slab is flat without crack. Top-loosening and aggregate exposure can be avoided so that problems such as corner missing, deckle edges, laps of slab slits and rainwater the drive rods are prevented and the drive rods are not corroded. The quality and appearance quality of the concrete slab construction are ensured in order to provide experience to concrete slab construction in the storage yard.

Description

technical field [0001] The invention relates to the field of engineering technology, in particular to the construction technology of large concrete slabs in storage yards. Background technique [0002] In the construction of large concrete slabs in the stockyard, there are generally problems such as inconvenient adjustment of formwork support, loose fixation, inaccurate position of dowel bars, cracks on the concrete top surface, loose top, corner drop of slab seams, burrs, heavy skin, etc., which have great impact on the project. Both intrinsic and perceived quality are adversely affected. Contents of the invention [0003] The present invention aims to solve the deficiencies of the prior art, and provides a large concrete slab construction process in a storage yard, and has carried out a series of process improvements on formwork production, support, concrete control, dowel installation, and slab seam treatment. [0004] In order to achieve the above object, the present ...
