It connects, another side exposes to pier shaft wall surface, for welding with bracket.Dowel built-in fitting is easy to appear dowel hole in the construction process
Hole circumferential concrete is not full, influences the globality requirement of original structure design；The mode of pre-embedded steel slab and bracket welding, due to needing
Overhead welding operation is wanted, difficulty of construction is larger, and welding quality not can guarantee.And the bracket of aforesaid way installation, stress performance
Limited, more demanding for stress performance large-scale cantilever type works cast-in-place construction bracket, existing bracket built-in fitting can not be protected
Demonstrate,prove construction safety.
Summary of the invention
The purpose of this utility model be in providing a kind of embedded part structure more stronger than existing bracket built-in fitting stress-bearing capability,
It is able to satisfy the needs of the bracket installation of bridge large size cantilever design construction.
The technical solution of the utility model is as follows:
A kind of bracket built-in fitting for bridge large size cantilever design Bracket method for construction, it is characterised in that: including muti-piece phase
The mutually parallel and vertical plate with horizontal plane has certain intervals between adjacent vertical plate, and one end of every piece of vertical plate and a connecting plate weld；
The plate face of the connecting plate is vertical with the plate face of the vertical plate, on connecting plate between every two pieces of vertical plates along and vertical plate plate face
Multiple screw holes are arranged in parallel direction, on connecting plate and the one side of vertical plate welding, welded at each screw hole an aperture with
The consistent nut of screwhole diameter, and the horizontal sealing end steel pipe of corresponding each nut setting one, one end of each sealing end steel pipe and company
Fishplate bar welds and by a nut cover in nozzle；It is provided with multiple rows of through-hole on every piece of vertical plate, is worn in the through-hole of each vertical plate face
Horizontally disposed transverse reinforcement is inserted, a bulkhead is respectively welded in the end of each row's transverse reinforcement.
In above-mentioned bracket built-in fitting, the vertical plate, connecting plate, transverse reinforcement and bulkhead are embedded in bridge pier shaft coagulation
In soil, the side plate face of the connecting plate exposes to pier shaft outer wall and flushes with pier shaft wall surface.
In above-mentioned bracket built-in fitting, the bulkhead is located on the outside of pier shaft reinforcing bar, and with pier shaft reinforcement welding.
The utility model uses vertical plate as main stress component, and passes through transverse reinforcement and bulkhead and pier shaft structure reinforcing bars
Built-in fitting and pier shaft are formed entirety by connection, and built-in fitting is connect with bracket using high-strength bolt, and the stress of built-in fitting can be improved
Performance, reduces that the hole circumferential concrete being easy to appear in traditional bracket built-in fitting work progress is full, overhead welding matter
Situations such as amount is not easy to control reduces security risk.
