then, a locking bolt 28 in the clamping mechanism is rotated downwards, a clamping plate 25 at the upper end inside the C-shaped pipe clamp 20 is extruded downwards through the locking bolt 28, the clamping plate 25 rotates towards the inside of the C-shaped pipe clamp 20 through a rotating shaft 24 to be tightened and drives a second spring 27 to elastically stretch, so that the clamping plate 25 is tightly clamped on the upper portion of a lower chord steel bar, and therefore the connection between the C-shaped pipe clamp 20 and the lower chord steel bar at the bottom end of a steel bar truss is completed, the C-shaped pipe clamp 20 and the lower chord steel bar at the bottom end of the steel bar truss are stably and firmly connected and are not prone to being separated, the universality of the C-shaped pipe clamp 20 is strong and convenient to use, finally, the steel bar truss floor bearing plates which are connected into a whole are fixed between two bearing beams to carry out corresponding concrete pouring construction, and when the basement membrane is subsequently disassembled, a first screw pin 3 in a first connecting plate 2 and a second screw pin 8 in a second connecting plate 7 can be taken out in a rotary mode, and the basement membrane can be completely disassembled.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art will understand that various changes, modifications and substitutions can be made without departing from the spirit and scope of the invention as defined by the appended claims. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
