A broken line shaped prefabricated concrete roof truss template fastening fixture and a construction method based thereon

PendingCN122500830AEasy to assemble and disassembleEasy to install
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.

A column formwork reinforcement device

ActiveCN224532227UImprove adaptabilityImprove versatility
The utility model provides a kind of construction column formwork reinforcing device, including construction column and four mounting racks, two fixed blocks are fixedly installed on mounting rack, fixed groove is set in the inside of two fixed blocks, the inside of two fixed grooves is slidably connected with connecting plate, and connecting rod and positioning rod are fixedly installed respectively in the both ends of two connecting plates. By pulling the pull ring, the locking of the first movable plate or the second movable plate is released, so that the first movable plate or the second movable plate inside the mounting rack slides along the guide rod through the guide block, the position is adjusted to adapt to different size templates, the versatility of the device for different size construction columns is improved, after adjusting to the appropriate position, the pull ring is loosened, the positioning rod is inserted into the corresponding positioning slot, and the position of the first movable plate or the second movable plate is fixed. And multiple positioning slots enhance the adaptability of the device to different construction column sizes.
