Abstract

The invention relates to an opposite-pull screw device for effectively controlling water loss and slurry leakage and an application method thereof. The opposite-pull screw device comprises an opposite-pull screw, a PVC tube and a spherical nylon stopper arranged on both sides of the PVC tube. Two end parts of the opposite-pull screw respectively pass through the spherical nylon stopper and a template and then are fixed with a fixed assembly. The fixed assembly comprises vertical square timbers, transverse square steels, gaskets and nuts on both sides of the opposite-pull screw. The spherical nylon stopper comprises a hemispherical sealing surface and a cylindrical butting part, and is of a solid structure of integral injection molding with a penetrating hole. According to the opposite-pullscrew device for effectively controlling water loss and slurry leakage and an application method thereof, the stopper at a PVC casing device is improved, the stopper with a spherical surface on one side is used. The connection between the PVC tube and the stopper of the casing device is made to be seamless at any position within the effective range by using the stopper with a spherical surface, the gap between the stopper and a template surface caused by the change of the position of the opposite-pull screw caused by the collision between the position of steel and the position of the opposite-pull screw is solved, and water loss and slurry leakage when placing concrete at the joint of the opposite-pull screw and the template is effectively prevented.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a pull screw device for effectively controlling water loss and slurry leakage and a use method thereof. Background technique [0002] At present, in fair-faced concrete projects, the pull bolt casing device is mainly to put a disposable plastic sleeve on the outside of the pull bolt rod, and to install plastic plugs on both sides. The commonly used plugs are hollow and stepped. Cylindrical plug, the plug is to insert the part with small diameter into one side of the PVC plastic pipe, and the part with slightly larger diameter on the other side is attached to the formwork; The bolt holes of the inner and outer formwork are on a straight line; however, in actual engineering, there are many situations where the screw positions of the tension bolts conflict with each other at the position of the reinforcement. The plugs on both sides are tightly attached to the formwork, but the...
