Abstract
A kind of pressure rackwork of sections pier shaft docking, it is characterized in that described pressure rackwork comprises the steel plate built-in fitting of lower joint pier shaft top end face, this steel plate built-in fitting is circular layout in the inner side of docking end face, on described steel plate built-in fitting, welding arranges lead, the top of lead has a tilt guides, oriented subordinate has a vertical limiting section, this vertical limiting section is equipped with level positioning jackscrew.Pressure rackwork reasonable in design, the operating efficiency of the docking of this sections pier shaft are high, it achieves as supporting body the fine setting that upper segment pier shaft transfers by lower joint pier shaft top end face forces in place, its assembly adopted is few, can manual adjustment, precision is high and handling safety is simple and direct.
Description
Technical field
The prefabricated subsection pier shaft that the utility model belongs to overhead road bridge carries out auxiliary equipment during docking operation, is specifically related to a kind of pressure rackwork carrying out the sections pier shaft docking that butt end surface construction forces contraposition to regulate when docking up and down sections pier shaft.
Background technology
Along with the development of bridge and overhead road bridge technology, marine or become the important engineering of bridge construction across the overhead road bridge construction in waters.Due to viaduct many employings Steel Continuous Box beam bridge, the supporter of non-navigation bridge mostly is prefabricate and install pier structure, can be divided into overall pier, cushion cap adds lower joint pier shaft, middle joint pier shaft and upper joint pier shaft Four types by classification.Because the overall weight of prefabricated pier shaft can reach more than 2000 ton, how to carry out effectively and safty hoisting and location and installation become the important technological problems needing solution, therefore can multi-segmental be divided into carry out pier shaft when carrying out prefabricated prefabricated, and then carry out on-the-spot docking construction.
The bottom pier shaft of segmented pier shaft and cushion cap in place after, when centering sections pier shaft or upper sections pier shaft carry out lifting docking operation, what need the sections pier shaft controlling top transfers precision, but the Dun Ding due to bottom pier shaft possesses certain height, and sections pier shaft to be transferred is in lifting state, adopt conventional pressure mechanism in place to be difficult to meet construction requirement, cause construction docking large deviations larger.
Utility model content
The utility model provides the pressure rackwork of the high sections pier shaft docking of a kind of reasonable in design, operating efficiency, it achieves as supporting body the fine setting that upper segment pier shaft transfers by lower joint pier shaft top end face forces in place, its assembly adopted is few, can manual adjustment, precision is high and handling safety is simple and direct.
The technical solution adopted in the utility model is as follows:
A kind of pressure rackwork of sections pier shaft docking, it is characterized in that described pressure rackwork comprises the steel plate built-in fitting of lower joint pier shaft top end face, this steel plate built-in fitting is circular layout in the inner side of docking end face, on described steel plate built-in fitting, welding arranges lead, the top of lead has a tilt guides, oriented subordinate has a vertical limiting section, this vertical limiting section is equipped with level positioning jackscrew.
Concretely, described docking end annular spread is provided with steel cushion block, and described steel cushion block is the multilayer Split type structure that superposition is arranged.
In one embodiment, described docking end face is the outer ring end face on lower sections pier shaft top end face, and described lead distributes setting inside its outer ring end face.
In one embodiment, the tilt guides of described lead is the firm structure body of chamfering that oblique outer ring end face is arranged, and the inclined plane of the firm structure body of described chamfering arranges rubber tile.
In another embodiment, described vertical limiting section has a upright steel column, and described level positioning jackscrew is positioned on this upright steel column.
The pressure rackwork of this sections pier shaft docking adopts the mode at pier shaft top end face pre-embedded steel slab when prefabricated lower joint pier shaft, provide the installation foundation of lead.The distance of pre-residual centimetre outside lead and between the inwall lifting upper joint pier shaft to be transferred.Be convenient to joint pier shaft and fall into leading truck.Lead is made up of with vertical limiting section the tilt guides of chamfering structure, and tilt guides guides and makes joint pier shaft fall into docking end region outside leading truck.And fine setting in place can be forced to the deviation of pier shaft, the accurate whereabouts of joint pier shaft in guarantee in the engineering that the level positioning jackscrew of vertical limiting section and upper assembling thereof falls at upper joint pier shaft.
The beneficial effects of the utility model are, pressure rackwork reasonable in design, the operating efficiency of the docking of this sections pier shaft are high, it achieves as supporting body the fine setting that upper segment pier shaft transfers by lower joint pier shaft top end face forces in place, its assembly adopted is few, can manual adjustment, precision is high and handling safety is simple and direct.
Below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.
Accompanying drawing explanation
Fig. 1 is the cut-away section structural representation of the utility model specific embodiment.
Detailed description of the invention
As shown in Figure 1, the pressure rackwork of this sections pier shaft docking has the steel plate built-in fitting 21 of lower joint pier shaft 20 top end face, this steel plate built-in fitting is six pieces, be circular layout in the inner side of docking end face 10, docking end face is the outer ring end face on lower sections pier shaft top end face, on steel plate built-in fitting, welding arranges lead 30, and lead is also distribution setting inside its outer ring end face accordingly.The top of lead 30 has a tilt guides 31, and the tilt guides of lead is the firm structure body of chamfering that oblique outer ring end face is arranged, and the inclined plane of the firm structure body of described chamfering arranges rubber tile.Oriented subordinate has a vertical limiting section 32, this vertical limiting section is equipped with level positioning jackscrew 33.Vertical limiting section has a upright steel column, and described level positioning jackscrew is positioned on this upright steel column.Docking end annular spread is provided with steel cushion block 40, and described steel cushion block is the multilayer Split type structure that superposition is arranged.
