Abstract
A kind of large-scale pier stud concrete reinforcement integral hoisting mechanical splice device, it is characterized in that described docking facilities comprises a stiff skeleton of integral hoisting, the top of this stiff skeleton is equipped with steel bar positioning frame, distributes the upper suspension centre of vertical reinforcement locating hole and this steel bar positioning frame is set on this steel bar positioning frame.This large-scale pier stud concrete reinforcement integral hoisting mechanical splice apparatus structure is reasonable in design, efficiency of construction is high, time saving and energy saving, it can realize the quickness and high efficiency docking of the cage of reinforcement before large-scale pier stud concrete pouring construction, reduce the loaded down with trivial details construction in interim location after existing reinforcing bar docks by root lifting, the speed of construction is promoted greatly, effectively reduce labour intensity simultaneously and improved working security.
Description
Technical field
The utility model belongs to the reinforcement construction technology of pier stud in the construction of viaduct road, is specifically related to the integral hoisting mechanical splice device of large-scale pier stud concrete reinforcement.
Background technology
Along with the development of traffic construction, increasing overhead road bridge needs Bridge Piers construction, and the cage of reinforcement that such Bridge Piers generally all adopts steel structure to tie up, then carries out concrete pouring construction.Because reinforcing bar in cage of reinforcement need to be realized vertical docking, to meet the requirement of strength of cage of reinforcement.In conventional concrete, in the construction technology of cage of reinforcement, need to carry out the prefabricated of cage of reinforcement entirety according to the structure that arranges of embedded bar in concrete.For Bridge Piers, its whole height and structure are comparatively huge, need to carry out setting up of peripheral various auxiliary support bodys according to construction requirement, and carry out the Primary Location by root lifting and after installing of steel reinforcement abutting joints, its difficulty of construction and construction sequence are too complicated, and this has had a strong impact on the construction of cage of reinforcement and whole pier column.
Utility model content
The utility model provides a kind of reasonable in design, high, the time saving and energy saving large-scale pier stud concrete reinforcement integral hoisting mechanical splice device of efficiency of construction, it can realize the quickness and high efficiency docking of the cage of reinforcement before large-scale pier stud concrete pouring construction, reduce the loaded down with trivial details construction in interim location after existing reinforcing bar docks by root lifting, the speed of construction is promoted greatly, effectively reduce labour intensity simultaneously and improved working security.
The technical scheme adopting that the utility model adopts is as follows:
A kind of large-scale pier stud concrete reinforcement integral hoisting mechanical splice device, it is characterized in that described docking facilities comprises a stiff skeleton of integral hoisting, the top of this stiff skeleton is equipped with steel bar positioning frame, distributes the upper suspension centre of vertical reinforcement locating hole and this steel bar positioning frame is set on this steel bar positioning frame.
In detailed description of the invention, described stiff skeleton is the space truss structure that lightweight section is welded, and comprises girder truss arranged in a crossed manner in length and breadth.
In one embodiment, the top of described stiff skeleton distributes suspension centre is set, and under described steel bar positioning frame, corresponding setting lifts with described stiff skeleton the positioning bolt being connected.
In another embodiment, the vertical reinforcement locating hole arranging on described steel bar positioning frame comprises reinforced bar sleeve, and reinforced bar sleeve has the fixing hole passing for reinforcing bar top.
Again in an embodiment, described stiff skeleton is around the vertical reinforcement spatial placement forming under steel bar positioning frame.
This large-scale pier stud concrete reinforcement integral hoisting mechanical splice device, according to the prefabricated concreting poor harsh requirement in the length of time of Large Bridge Pier, has been realized low idle job and has been carried out the time saving and energy saving lifting docking of cage of reinforcement.Stiff skeleton is the space truss structure of the girder truss in length and breadth combination that is welded of lightweight section, after can being processed into unit trussed construction, be assembled into overall structure, stiff skeleton is arranged in cage of reinforcement for increasing steel bar overall rigidity and stability, when steel bar overall lifting, column truss by stiff skeleton is stressed, reinforcing bar is attached on truss and lifts with truss integral, can effectively improve the stability of overall reinforcing bar lifting and mechanical splice.Steel bar positioning frame winches to end face and carries out in placely after stiff skeleton installation, and the corresponding stiff skeleton in locating rack bottom, utilizes positioning bolt or screw rod stiff skeleton can be reinforced the connection into overall structure with locating rack.Vertical reinforcement utilizes sleeve all to reinforce on locating rack, and therefore, locating rack plays again and disperses to bear the effect of vertical load, thereby has reduced the requirement to stiff skeleton rigidity.
The beneficial effects of the utility model are, this large-scale pier stud concrete reinforcement integral hoisting mechanical splice apparatus structure is reasonable in design, efficiency of construction is high, time saving and energy saving, it can realize the quickness and high efficiency docking of the cage of reinforcement before large-scale pier stud concrete pouring construction, reduce the loaded down with trivial details construction in interim location after existing reinforcing bar docks by root lifting, the speed of construction is promoted greatly, effectively reduce labour intensity simultaneously and improved working security.
Below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.
Detailed description of the invention
As shown in Figure 1, this large-scale pier stud concrete reinforcement integral hoisting mechanical splice device is mainly made up of stiff skeleton 10, steel bar positioning frame 20, stiff skeleton 10 and steel bar positioning frame 20 can carry out integral hoisting by suspension bracket 30, the top assembling steel bar positioning frame of this stiff skeleton, distributes on this steel bar positioning frame the upper suspension centre 21 of vertical reinforcement locating hole 22 and this steel bar positioning frame is set.Stiff skeleton 10 is the space truss structure that lightweight section is welded, and comprises girder truss arranged in a crossed manner in length and breadth.Stiff skeleton 10 is around the vertical reinforcement spatial placement forming under steel bar positioning frame.In the time carrying out pier stud concreting with together with the reinforcing bar of lifting as cage of reinforcement.The top of stiff skeleton distributes suspension centre is set, and under described steel bar positioning frame, corresponding setting lifts with described stiff skeleton the positioning bolt 23 being connected.The vertical reinforcement locating hole arranging on steel bar positioning frame comprises reinforced bar sleeve, and reinforced bar sleeve has the fixing hole passing for reinforcing bar top.
