[0002] In steel structure construction, the construction sequence is usually steel structure column-steel structure beam-truss floor laying-flat steel bar binding-concrete pouring; before pouring, the truss floor is usually divided into two cases of steel pipe back support and non-back support according to the pouring thickness of concrete and the erection span of truss floor. Under normal circumstances, it is easy to back up when the floor height is low, but it becomes very difficult to back up in the high area, which originally needs one row of frame pipes to become two rows or even three rows or four rows, and the danger coefficient increases during construction, the construction period is prolonged, and the concrete pouring cannot be timely connected with the previous process.

[0003] Therefore, how to solve the above technical problems has become the subject of the utility model. INVENTION CONTENTS
