Abstract
The utility model relates to a bracket on a bridge pier top, in particular to a diagonal draw type bracket for cast-in-place of a continuous beam. The bracket comprises a pier body (1) and a pier top section box girder (2) erected on the pier body (1), and is characterized in that steel corbels (4) are inserted into the outer side wall of the pier body (1) for supporting, a ceiling mount bracket is anchored on the pier top section box girder (2), a formwork system (7) is fixed on a truss (5) of the ceiling mount bracket, and a cast-in-place beam of an initiation section box girder (3) is positioned on the formwork system (7) on two sides of the pier top section box girder (2). The cast-in-place of the starting block of the continuous beam is handy and convenient, meanwhile operations like welding high above the ground and cutting-off are not required during the installation and removal, the stress is reasonable, the stability is good, a large number of temporary steel products is saved, and the disassembly is convenient and quick.
Description
Technical field
The utility model relates to a kind of bridge pier jacking frame, particularly a kind of continuous beam cast in situs cable-stayed type carriage.
Background technology
Along with the development of Traffic Construction in China's West, the high Construction of continuous beam above 50m of pier is more and more general.Build a preceding necessary link as continuous beam cantilever, starting block must be built on the support with enough rigidity and intensity, the general pier jacking frame that adopts when the pier height surpasses 50m.
This class carriage is generally made triangular form, presents the characteristic of cantilever force truss, and two points up and down of triangle are connected with pier shaft by being welded to connect steel plate, and another point is the end of cantilever truss, bears starting block concrete weight.This truss is owing to cantilever force, and highly higher for satisfying rigidity and requirement of strength, the temporary steel material use quantity is big, and the assembling and disassembling workload is big, and security risk is big.
Summary of the invention
The purpose of this utility model is to provide a kind of continuous beam cast in situs cable-stayed type carriage that a kind of light bridge is convenient, installing and remove simultaneously need not the high-altitude welding, cut off for continuous beam starting block cast-in-site.
The purpose of this utility model is achieved through the following technical solutions, design a kind of continuous beam cast in situs cable-stayed type carriage, the pier top section case beam that comprises pier shaft and on pier shaft, build, it is characterized in that: the pier shaft lateral wall is inserted with steel corbel and supports, anchoring has ceiling mount bracket on the section case beam of pier top, fixed form system on the truss of ceiling mount bracket, cast-in-place continuous beam starting block is on the template system of section case beam both sides, pier top.
Described ceiling mount bracket is symmetrical distribution with pier shaft and pier top section case beam center line, ceiling mount bracket comprises interconnective oblique drawstring and truss, tiltedly an end of drawstring is anchored at the bottom of pier top section case beam, the other end links to each other with the cantilever end of truss, fixedlys connected with the steel corbel of pier shaft lateral wall in the root arm bottom of truss.
Described pier shaft lateral wall is provided with the reservation notch of grafting steel corbel.
Described template system bottom surface is provided with support member, and template system is the skewed high outside and low outside inversed taper platform structure of formation that extends upward along the boss bottom surface of pier top section case beam.
Described template system upper surface is covered with channel-section steel and steel plate.
The ingenious mechanics principle that utilizes of the utility model, cable-stayed type carrier structure reasonable in design, utilize completed pier top section case joist support to be subjected to most of The initial segment case beam concrete weight to be cast, by being anchored in the oblique drawstring tractive carriage cantilever end on the section case beam of pier top, it is stressed into freely-supported to become the carriage cantilever force.Make carriage present the freely-supported stress, stressed reasonable, good stability is saved a large amount of interim steel, and peace is torn open convenient and swift.
Description of drawings
Below in conjunction with the embodiment accompanying drawing the utility model is described further.
Fig. 1 is the cast-in-place cable-stayed type carrier structure of an embodiment continuous beam starting block schematic diagram.
Among the figure: 1, pier shaft; 2, pier top section case beam; 3, continuous beam starting block; 4, steel corbel; 5, truss; 6, oblique drawstring; 7, template system; 8, reserve notch.
Specific implementation method
As shown in Figure 1, the cast-in-place cable-stayed type carriage of this continuous beam starting block, the pier top section case beam 2 that comprises pier shaft 1 and on pier shaft 1, set up, pier shaft 1 lateral wall is inserted with steel corbel 4 and supports, and anchoring has ceiling mount bracket on the section case beam 2 of pier top, ceiling mount bracket comprises interconnective oblique drawstring 6 and truss 5, fixed form system 7 on the truss 5 of ceiling mount bracket, and starting block case beam 3 is cast-in-place on the template system 7 of section case beam 2 both sides, pier top.This ceiling mount bracket is symmetrical distribution with pier shaft 1 and pier top section case beam 2 center lines, ceiling mount bracket comprises interconnective oblique drawstring 6 and truss 5, tiltedly an end of drawstring 6 is anchored at the below of pier top section case beam 2, the other end links to each other with the cantilever end of truss 5, and the root arm bottom of truss 5 firmly is connected with the steel corbel 4 of pier shaft 1 lateral wall.When constructing at pier shaft 1 top, pier shaft 1 lateral wall is provided with the reservation notch 8 of grafting steel corbel 4, and filling between notch 8 and the bracket is closely knit.
Template system 7 bottom surfaces are provided with support member, and template system 7 is the skewed high outside and low outside inversed taper platform structure of formation that extends upward along the boss bottom surface of pier top section case beam 2.Template system 7 upper surfaces are equipped with and are used for channel-section steel and steel plate.Because adopt this structure, steel corbel 4 is passed to pier shaft with the part of continuous beam starting block 3 loads, tiltedly 6 of drawstrings with other Load Transfer to a pier top section case beam 2.Truss 5 directly bears whole loads of The initial segment case beam 3 as the support of template system 7.Make carriage present the freely-supported stress, and its stressed rationally, good stability.
The construction principle of the cast-in-place cable-stayed type carriage of continuous beam starting block is: the oblique drawstring 6 of construction pier top section pier top section case beam 2 anchorings.Ceiling mount bracket truss 5 one ends are held on steel corbel 4, and cantilever end is connected with oblique drawstring 6.After accurately adjusting the truss position, after truss 5 and steel corbel 4 be connected firmly, remove lifting.With truss 5 is support, and the template system 7 of starting block 3 is installed thereon.Build The initial segment case beam 3 concretes, and health is to prescribed strength post tensioning prestressing force.
Unload and stripping system 7, loosen oblique drawstring 6, truss 5 breaks away from the concrete surface, and lifting truss 5 is finished carriage and removed to ground.
