[0002] Concrete door leaf steel frame group is generally used on civil air defense doors. Civil air defense doors are the doors at the entrances and exits of civil air defense projects. They have the function of blocking blasting and can play a great protective role in times of crisis.
[0003] In the prior art, when welding multiple steel plate components, it is necessary to insert the connectors on the steel plate components into the positioning holes opened on the platform to position the multiple steel plates, and then place the door panels on the multiple steel plates by means of a hoist, and then manually weld them. Although this method of positioning the steel plates by directly inserting the connectors is simple, it has the following disadvantages: if a person accidentally touches a steel plate, the connector will rotate in the positioning hole, causing the angle of the steel plate to change. After the door panel is placed, it is difficult for the person to dock the steel plate with the door panel, and the person can only lift the door panel again by means of a hoist to correct the steel plate, which is a relatively troublesome operation. Therefore, a concrete door panel welding and positioning tool is designed to solve the above disadvantages. Utility Model Content

[0024] Specifically, the connecting piece 16 is inserted into the positioning hole 14, and the steel plate 15 is stuck in the positioning groove 13. After multiple steel plates 15 are installed, the door leaf body 200 is placed on the two support plates 2 through a sling.

The support seat is fixedly connected to the front end of the support plate 2, and a handwheel is installed at one end of the worm 20.
[0028] Specifically, by starting multiple first cylinders 6, multiple square columns 3 respectively drive multiple sliding seats 4 to slide on multiple slide rails 5, so that the relative positions of the two support plates 2 can be adjusted.
