Description
Technical field
The utility model is related to the technical field that bridge attachment structure is designed, more particularly to a kind of prefabricated bent cap to be stood with prefabricated
The assembled attachment structure of post.
Background technology
At present, with the continuous propulsion that Chinese Urbanization is built, people gradually propose green ring to Urban Bridge Construction
Guarantor, the construction requirements of efficient energy-saving.Urban Bridge cast in situs generally requires blocked road when constructing, and the construction period is long, construction
Quality is difficult to control, and support in construction, template consumption are big, and operating expenses is high, directly affects the road of construction point
Ability, and carry out the pollution such as dust, noise to urban belt when concrete material construction and transport, have a strong impact on citizens' activities and life
Bioplasm amount, often results in larger resentment, and the requirement with urban construction and development is incompatible with.
It is one of emphasis of bridge construction that bent cap in bridge is connected with column.If pier column uses precast plant with bent cap
It is prefabricated, after on-site hoisting is in place, the connected mode of assembled bent cap and column, then can parallel construction, greatly shorten the construction period, subtract
It is small concrete shrinkage can be reduced to surrounding traffic, the influence of resident living, and element precast, the deformation for causing of creeping, construction
Quality is guaranteed, there is preferable society, environmental benefit.With cast in situs pier column compared with bent cap, assembly pier stands
Post and bent cap have can scale it is prefabricated, transport and it is easy for installation the advantages of, obtain relatively widely answering in bridge construction field
With.According to being actually needed for bridge modernization construction, need that a kind of bonding strength of invention is high badly, easy construction effectively, economic benefit
Good prefabricated bent cap and the assembled attachment structure of prefabricated stand column.
Utility model content
To meet being actually needed for Urban Bridge modernization construction, the utility model proposes a kind of bonding strength it is high, construction
It is simple and effective, good in economic efficiency for prefabricated bent cap and the assembled attachment structure of prefabricated stand column.
To achieve these goals, the technical solution of the utility model is as follows：
The assembled attachment structure of a kind of prefabricated bent cap and prefabricated stand column, including prefabricated bent cap 1 and prefabricated stand column 2, it is described pre-
Bent cap processed 1 is provided with the big cylinder hole groove 3 being mutually communicated up and down, and the bottom surface of prefabricated bent cap 1 is prefabricated to be provided with four small columns 4；It is described
A big cylinder 5 is provided with the middle of the top of prefabricated stand column 2, big cylinder is formed around four small column hole grooves 6.
Four small columns 4 be cased with FRP pipe, FRP pipes imbedded in advance with the bottom surface junction of prefabricated bent cap 1 it is certain
Depth is in bent cap body；The big cylinder 5 is cased with FRP pipes, and FRP pipes are with the embedment in advance of the top surface junction of prefabricated stand column 2 necessarily
Depth in column.
The size of the big cylinder hole groove 3 of the prefabricated bent cap 1 matches with the size of the big cylinder 5 of the prefabricated stand column 2,
The size of the small column 4 of the prefabricated bent cap 1 matches with the size of the small column hole groove 6 of the prefabricated stand column 2, so that described
Prefabricated bent cap 1 and the mutually nested assembly of prefabricated stand column 2.
It is high-strength by the implantation that drills in relevant position after the completion of the assembly mutually nested with prefabricated stand column 2 of prefabricated bent cap 1
Shank of bolt 7 is anchored, and prefabricated bent cap 1 and prefabricated stand column 2 are connected as into entirety.
In sum, the utility model each several part component is prefabricated in the factory, existing in construction without poured in place concrete
After the hoisting prefabricated bent cap 1 in field and the assembly of prefabricated stand column 2, only need to be by the implantation anchoring of high-strength bolt bar 7, the connection knot of drilling
Structure construction is convenient, and difficulty is low, and prefabricated bent cap 1 and prefabricated stand column 2 are connected as into entirety well.
