3-4 pre-embedded reinforced fin plates are arranged.
The external bracket comprises a horizontal plate, a longitudinal fixing plate and a reinforcing rib plate, the horizontal plate is fixed at the upper end of the longitudinal fixing plate, the reinforcing rib plate is fixed between the horizontal plate and the longitudinal fixing plate, and a bolt hole matched with the position of the internal thread pipe is formed in the longitudinal fixing plate.
And the pre-embedded reinforcing fin plate is welded and fixed with the reinforcing steel bars inside the concrete of the silo wall.
Compared with the prior art, the invention has the beneficial effects that:
the invention provides a silo suspended support type steel truss bracket supporting structure which is applied to cast-in-place roof construction of high and large silo construction (building), is particularly used for supporting a suspended support type steel truss when a roof cast-in-place structure is constructed by a suspended support method by using a slip form operation platform by adopting a slip form process, is convenient to install and disassemble, is convenient to operate, simplifies the construction process, saves the construction cost, reduces the potential safety hazard and shortens the construction period on the premise of meeting the action strength of a large load.
