Abstract

The utility model discloses a kind of bridge construction hanging device by the use of precast main beam as primary structure member, the supporting support including loading arm and the support loading arm is provided with lifting winch on the loading arm;The loading arm is made of gooseneck and two pre-manufactured steel beam elements being vertically arranged at the top of the gooseneck, and the two pre-manufactured steels beam element is connected as a single entity by the steel truss between being disposed therein;The supporting support is connected with the pre-manufactured steel beam element bottom plate, and the lifting winch is movably arranged on the gooseneck.The utility model has the advantage of the main bearing members that construction hanging device is formed after the pre-manufactured steel girder of bridge is connected by steel truss, coordinate the method for hoist cable installation girder steel, the stress of girder can effectively be improved, both can meet steel reinforced concrete combination beam installs and uses demand, it again can be to avoid increase expense, it with simple structure, constructs the advantages of convenient, practicability is stronger.

Description

By the use of precast main beam as the bridge construction hanging device of primary structure member
Technical field
The utility model is related to bridge construction hanging device, more particularly, to a kind of by the use of precast main beam as stress structure The bridge construction hanging device of part.
Background technology
Steel-concrete Combined Beam Structures are another class important feature form, its energy after steel construction and concrete structure Both comprehensive reapective features, to solve superelevation, providing new choosing across the special designing construction difficult problem of, heavy duty, labyrinth greatly It selects.
In terms of system stress, for steel-Combined concrete simply supported beam, upper limb concrete slab is pressurized, lower balsh The advantages of beam tension, it can give full play to steel tensile strength height and high concrete crushing strength, makes up the deficiency of homogenous material.
In terms of bridge construction, steel reinforced concrete combination beam uses prefabricated construction, can quickly finish the assembly of bridge structure, but It is to apply man-hour requirement using bridging equipment, the bridging equipment of generally use is walking bridging machine etc..Due to bridging equipment very Costliness, when overall length of bridge is larger, the expense that Bridge Erector is shared to each hole is more reasonable, but for the bridge of Mid and minor spans Beam using bridge formation machine equipment, is shared costly to every hole, greatly improves construction cost.
Invention content
The purpose of this utility model is to provide a kind of bridge construction liftings by the use of precast main beam as primary structure member Equipment can overcome the problems, such as that Bridge Erector equipment cost is excessively high in construction method.
To achieve the above object, the utility model can take following technical proposals:
Bridge construction hanging device described in the utility model by the use of precast main beam as primary structure member, including load-bearing Arm and the supporting support for supporting the loading arm, are provided with lifting winch on the loading arm;The loading arm is by gooseneck With the two pre-manufactured steel beam elements composition being vertically arranged at the top of the gooseneck, the two pre-manufactured steels beam element is by being disposed therein Between steel truss be connected as a single entity;The supporting support is connected with the pre-manufactured steel beam element bottom plate, the lifting winch activity It is arranged on the gooseneck.
The pre-manufactured steel beam element is made of bottom plate and two skew web plates;Skew web plate lower part water close to the steel truss side It is flat to be provided with connection web, it is connected at the top of the top of the steel truss and the skew web plate of the pre-manufactured steel beam element, the steel The bottom of truss is connected with the connection web.
The section of the steel truss is in rectangular configuration, and internal chiasma is provided with reinforcement truss.
The steel wire tow line end of the lifting winch is connected with hoist cable.
The utility model has the advantage of construction lifting is formed after the pre-manufactured steel girder of bridge is connected by steel truss The main bearing member of equipment, the method for cooperation hoist cable installation girder steel, can effectively improve the stress of girder, both can be with Meet the demand of installing and using of steel reinforced concrete combination beam, and can there is simple structure, construct the advantages of convenient to avoid expense is increased, Practicability is stronger.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the structure chart of girder steel unit in Fig. 1.
Specific embodiment
As shown in Figure 1, 2, the bridge construction lifting described in the utility model by the use of precast main beam as primary structure member Equipment, the supporting support 1 including loading arm and support loading arm;Lifting winch 2 is provided on loading arm;It is constructed into reduce This, the loading arm of the utility model is made of gooseneck 3 and two pre-manufactured steel beam elements 4 being vertically arranged at the top of gooseneck 3, and two is pre- Girder steel unit 4 processed is connected as a single entity by the steel truss 5 between being disposed therein:Pre-manufactured steel beam element 4 is by 4.1 and two skew web plate of bottom plate 4.2 composition;Skew web plate lower horizontal close to 5 side of steel truss is provided with connection web 4.3(It is welded on skew web plate), end There are bolt interface, the top of steel truss 5 is connected with the skew web plate top girth of pre-manufactured steel girder 4 by bolt, steel truss 5 Bottom be connected with connecting web 4.3 by bolt;To ensure its stress intensity, the section of the steel truss 5 of the utility model In rectangular configuration, internal chiasma, which is provided with, strengthens truss 5.1.Supporting support 1 is connected with 4 bottom of pre-manufactured steel girder(It can adopt With the mode connected temporarily), lifting winch 2 is movably arranged on gooseneck 3, facilitate in work progress the installation of hoist cable 2.1 and Lift the transverse shifting of winch 2.
When assembled, two pre-manufactured steel beam elements 4 and steel truss 5 are connected into completion first, are then pushed up using Lifting Equipment After rising to hoisting height, gooseneck 3 is installed, forms hanging device girder;Then installation lifting winch 2(Including by lifting winch 2 Control the hoist cable 2.1 of lifting)With supporting support 1, construction Lift-on/Lift-off System is formed.Primary structure member should be carried out in advance before construction strong Degree experiment measures it and lifts weight, ensures lifting construction safety.
During construction, girder steel 7 to be set up is transported to designated position by beam car 6, by steel by the way of " transporting beam under beam " Beam 7 lifts in place, and then hoist cable 2.1 is fixedly connected with the piece that hangs on girder steel 7, is locked after pulling force is stretched to certain value, peace Precast concrete floorings are filled, pour into a mould the wet joint concrete of floorings.After the wet joint concrete of floorings reaches design strength, It releases hoist cable and hangs the connection of piece.Take same form of construction work by the second hole steel girder erection it is in place after, by first and second hole steel Beam welding or bolt, the system transform of completion every two hole girder steel " Simply supported non-uniform ", and the second bridge of constructing are born curved across non-pier top The concrete slab in square area, then the wet joint concrete of area's floorings and pier top underplate concrete in casting bay, pour into a mould pier top Hogging moment area inner lining concrete.During last holes of constructing, hanging device is advanced in place, using supporting support 1, be will act as lifting and is set Two standby pre-manufactured steel beam elements 4 are put in place, and complete the system transform of girder steel Simply supported non-uniform.After the completion for the treatment of girder steel deformation, press According to prefabricated bridge, the construction of integrin bridge is completed.
