Description
Technical field
The utility model is related to a kind of large-span continuous beam cast-in-place support frame support bracket structure.
Background technology
At present, the Continuous beam design of the general large span of construction of railways is constructed using the method for hanging basket cantilever, with
Across the increasing of rivers and highway continuous beam, limit carries out 0 number section construction using console.Traditional landing
Requirement of the formula support to foundation bearing capacity is higher, and is limited by landform, therefore continuous bridge is applied when across rivers and highway
The number section of work 0 is restricted using console, cannot often meet construction requirement.Even if being adopted in the case of conditions permit
Constructed with console, it exists long in time limit, and material consumption is big, the poor shortcoming of economic benefit.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of number section of large-span continuous beam 0 construction cast-in-place support branch
Support bracket structure, to overcome due to being limited and cannot often increase material input and influence construction using floor stand by landform
The deficiencies such as duration.
The utility model solves the technical scheme that its technical problem used：Using prefabricated shelf bracket, pre-buried pier shaft
The combined bracket structure that interior steel plate bracket and connector are combined, combined bracket is used above Bailey beam, is set respectively in Bailey beam
Put the truss of box beam base plate load-bearing and the I-steel distribution beam of box beam wing plate load-bearing；I-steel distribution beam is used above bowl fastening type to expire
Hall support, that is, form overall structure.
Shelf bracket and steel plate bracket welding rigid connection in pre-buried pier shaft.
Connected using connector between the shelf bracket of pier shaft both sides.
Connector uses diameter phi 32mm fining twisted steels, and applies prestressing force.
Bailey beam is using truck crane integral hoisting after mono- group of 2 Pin at the scene preassembling and forms entirety.
Using the bed die system of Hanging Basket at the top of carrier structure, side form system carries out No. 0 as the bed die and side template of 0 number section box beam
Section construction.
The beneficial effects of the utility model are, according to the loading characteristic rationale design of scaffolds of the number section of continuous beam 0, the peace of support
Dress with remove it is convenient, solve across the territory restriction such as rivers and highway, it is necessary to timbering material negligible amounts, construction is fast
Speed, low cost.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the side view in Fig. 1；
Fig. 3 is the top view in Fig. 1.
Specific embodiment
Embodiment of the present utility model：Across highway and the rivers section number section of continuous beam 0, using prefabricated shelf bracket 2, pre-
The combined bracket structure that steel plate bracket 1 and connector 3 are combined in pier shaft is buried, combined bracket is used above Bailey beam 4, Bailey beam
The truss 5 of box beam base plate load-bearing and the I-steel distribution beam 6 of box beam wing plate load-bearing are respectively provided with 4；Above I-steel distribution beam 6
Using bowl fastening type full framing 7, that is, form overall structure.
Shelf bracket 2 and the welding of steel plate bracket 1 rigid connection in pre-buried pier shaft.
Connected using connector 3 between pier shaft both sides shelf bracket 2.
Connector 3 is coupled and applies prestressing force using diameter 32mm fining twisted steels to drawing.
Bailey beam 4 is using truck crane integral hoisting after mono- group of 2 Pin at the scene preassembling and forms entirety.
Using the bed die system of Hanging Basket at the top of carrier structure, side form system carries out No. 0 as the bed die and side template of 0 number section box beam
Section construction.
Construction method is described below.
First, the construction of pier shaft pre-embedded steel slab bracket and shelf bracket is prefabricated.
Anticipate as shown in Figure 1 and Figure 2, it is during pier construction that steel plate bracket 1 is pre-buried to design attitude, and ensure it is pre-buried accurately exist
Weld horizontal steel plate on vertical steel plate bracket；The welding production of shelf bracket 2 is carried out in precasting yard, each position is carried out before appearance
Defect detecting test ensures welding quality.
Secondly, the installation of shelf bracket.
Prefabricated shelf bracket 2 is transported into scene to be lifted, shelf bracket 2 and pier shaft pre-buried steel in place will be lifted
The horizontal steel plate of plate bracket 1 carries out welding rigid connection.After calf support is installed before and after the mmPVC of pre-buried φ 50 pipes, pier near pier top
Using 4 φ 32mm finish rolling deformed bars connectors, 3 pairs of drawings, and prestress application is carried out, form the major bearing structures of bracket.
The connection fining twisted steel connector 3 to shelf bracket 2 carries out tensioning applying prestressing force successively.
Finally, the Bailey beam installation of shelf bracket above section.
Bailey beam 4 uses two Pin combined hangings, and lifting ensures that its underpart is closely connected with the top surface of shelf bracket 3, and Bailey beam is installed
Base plate truss principal 5 can be carried out after in place and wing plate distributes the lifting of I-steel 6, base plate truss principal 5 and wing plate distribution I-shaped
Steel 6 is required to carry out horizontal connection using I-steel, to ensure lateral stability.
I-steel 6 is above is bowl fastening type full framing 7.
