A formwork for narrow and long deformation joints and its construction method

Abstract

The invention provides a formwork for narrow and long deformation joints, which includes a combined force transmitter and a steel formwork, the combined force transmitter is vertically fixed on the steel formwork at a certain distance, and the combined force transmitter includes a first force transmitter and a second force transmitter and the third power transmission device; the second power transmission device can be set inside the second support channel steel, and the positioning card is inserted into the iron plate, so that the first power transmission device, the second power transmission device, the third power transmission device and the steel formwork Become a whole; the round steel with holes is between the first special-shaped steel backing plate and the second special-shaped steel backing plate, and squeeze the first special-shaped steel backing plate and the second special-shaped steel backing plate at the same time, and play the role of transmitting side pressure ; The present invention also provides the construction method of the above-mentioned narrow and long deformation joint formwork. The combined power transmission device of the present invention can be shrunk, and while satisfying the pouring of the walls on both sides of the deformation joint, it can be easily removed after pouring; the processing is simple, the material is easy to obtain, it can be used repeatedly, the operation is convenient, and the manpower input is reduced. The apparent quality of the concrete in the deformation joint is good.

Description

technical field [0001] The invention belongs to the technical field of building engineering construction, and in particular relates to a formwork for narrow and long deformation joints and a construction method. Background technique [0002] In industrial and civil buildings, due to the needs of function and use, multiple buildings are often designed adjacent to each other, and narrow and long deformation joints are formed between the buildings. Adjacent buildings are not affected. [0003] In the existing narrow and long deformation joints pouring concrete wall construction, foam boards are usually inserted into the deformation joints as a formwork for pouring concrete, but the foam boards are difficult to remove after construction; PVC pipes are also used in civil buildings to penetrate into the wall. The construction method of welding nuts on the keel of the formwork, the quality of the plugging of the bolt holes after the construction of this method cannot be verified, ...
