Double-column formwork structure at deformation joint position and construction method thereof

Abstract

The invention relates to a double-column formwork structure at a deformation joint position and a construction method thereof. The double-column formwork structure comprises two column formworks, opposite-pull rods and clamping assemblies, wherein pouring spaces are formed in the two column formworks correspondingly, the two column formworks are oppositely arranged, and a deformation joint is formed between the two column formworks; the opposite-pull rods are transversely arranged on the two opposite sides of the column formworks in a penetrating mode and are perpendicular to the deformation joint, the first ends of the opposite-pull rods are located in the deformation joint, and nuts are screwed at the second ends of the opposite-pull rods; and the clamping assemblies are transversely arranged in the deformation joint, the clamping assemblies are clamped and fixed to the first ends of the opposite-pull rods in a detachable mode and abut against the column formworks, and the opposite-pull rods are pulled to the two opposite sides of the column formworks to be fixed by adjusting the nuts to be tightly attached to the column formworks. According to the double-column formwork structure at the deformation joint position and the construction method thereof, the clamping assemblies are clamped and fixed to the first ends of the opposite-pull rods and abut against the column formworks, screws do not need to be screwed at the deformation joint position, and construction is more convenient; and the clamping assemblies can serve as reinforcing keels of the formwork structure, and the overall stability is enhanced.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a double-column formwork structure at a deformation joint position and a construction method thereof. Background technique [0002] Deformation joints are the general term for expansion joints, settlement joints and seismic joints. Buildings are often deformed under the action of external factors, resulting in cracking or even destruction. Deformation seams are structural seams reserved for this situation. [0003] In the double-column formwork operation of the deformation joint of the reinforced concrete frame structure, the formwork of the two columns is usually supported separately, and the corresponding formwork is connected by the tension screw rod, and the foam plastic board is sandwiched in the deformation joint between the columns for isolation and maintenance. Doubles as a template, and finally destructively pulls out the foam board. However, it is difficult to tu...
