A broken line shaped prefabricated concrete roof truss template fastening fixture and a construction method based thereon
This invention relates to the field of building construction technology, and in particular to a formwork fastening clamp for a zigzag precast concrete roof truss and a construction method based thereon. The formwork fastening clamp includes a first insert, a second insert, a bottom crossbar, and a locking device. The bottom crossbar is connected to the first and second inserts via a socket joint and is locked in place by the locking device. This invention solves the problems existing in the prior art and provides an integrated solution for formwork fastening, sleeper support, hoisting gap reservation, and prevention of concrete adhesion. After the precast beam is demolded, the bottom crossbar can be directly left below the beam to act as a sleeper, and the upper beam can still be directly precast on top of the lower beam. During hoisting, there is a rope gap between the two beams, which effectively avoids concrete adhesion between the upper and lower beams, improving the forming quality and construction efficiency of the zigzag precast concrete roof truss.
