Concrete frame structure.Since reinforcing bar is more and construction space limits for bean column node region arrangement, template construction and coagulation is poured
Construction is more inconvenient when native, causes the concrete construction quality of node region lower, the performance requirement of " waiting cast-in-place " is not achieved.?
Existing beam-ends is reserved in the prefabrication and assembly construction concrete frame structure of keyway, and the space for reserving keyway is smaller, arranges bending reinforcing steel bar
Can effective reinforcing steel bar anchoring property, but difficulty of construction is larger, moreover, bending when arranging bending reinforcing steel bar
Connection reinforcing bar is easy to appear connection when deviation occurs in position due to disturbance when steel bar arrangement position deviation is larger or casting concrete
The problems such as reinforced steel bar strength cannot be met the requirements；When existing prefabrication and assembly construction concrete frame structure carries out construction and installation at the scene,
Beam column is required to the temporary support of temporary support, especially beam for the progress of serious limitation site operation, therefore solves prefabricated structure
Part temporary support in the construction process and installation are to promote the importance of building industrialization.
