The screw is coaxial. When in use, screw the two screws into the two ends of the sleeve respectively, so that the two steel plates respectively withstand the two side wall formworks of the corridor, and then turn the sleeve so that the two screws extend outward at the same time to make the steel plates tight At the same time, the screw rod can be extended or contracted by rotating the sleeve to adjust the stretching degree of the screw rod so as to realize the accurate positioning of the template.

One side of the steel plate is a plane, and the side opposite to the plane is provided with a groove, and the flat surface between the screw rod and the steel plate

surface welding. Usually, the side wall formwork is fixed by steel pipes. The grooves of the steel plates in this technical solution face outwards and can be directly stuck on the steel pipes, which can prevent the steel plates from shifting due to sliding and other reasons during the installation process, thereby affecting the accuracy of positioning.

The steel plate can be made of channel steel, the plane of the screw rod and the channel steel is welded, and the groove of the channel steel faces outward.

For easy operation, a handle is provided on the sleeve.

For simple and firm structure, the sleeve is steel pipe, the handle is steel bar, and the handle is welded to the sleeve.

The second object of the present invention is achieved in that the positioning method utilizing the above-mentioned corridor side wall formwork positioning device comprises the following steps:

1. Screw two screws with one end welded to the steel plate into the two ends of the sleeve respectively;

2. Align the grooves of the two steel plates with the steel pipes that fix the side wall formwork, and turn the sleeve to extend the screws at both ends at the same time, so that the grooves of the steel plates are stuck on the steel pipes and tightened.

3. Check whether the positioning of the template is accurate, adjust the expansion and contraction of the screw by rotating the sleeve, so that the template can be positioned accurately.

For structural stability, a corridor side wall formwork positioning device is installed at intervals of 2 meters along the length of the corridor, and three corridor side wall formwork positioning devices are installed along the corridor's up and down direction.

After the project is finished, the screw is recovered by turning the sleeve, and the steel plate is separated from the steel pipe.

The present invention has following beneficial effects:

1. The corridor side wall formwork positioning device of the present invention is formed by connecting a sleeve, a screw and a steel plate. It has a simple structure and is easy to use. Rebar is saved, labor is saved, and engineering costs are reduced.

2. The corridor side wall formwork positioning device of the present invention is simple to process, quick and convenient to install and remove, reusable, and occupies a small storage space, and is suitable for positioning all corridor concrete formworks.

3. The positioning method of the present invention is simple and convenient, can quickly complete the construction and dismantling of the positioning device, improves work efficiency, and helps to shorten the construction period.
