Abstract
The utility model relates to an arch rib detains tower steel-pipe pile basis locating rack, including the locating frame of two rectangles, every locating frame includes 4 locating plates that set up according to 4 summits of rectangle, sets up a steel-pipe pile jack in the middle of every locating plate, 4 locating plates are according to the side welding 4 flat link rods of rectangle between 4 locating plates, weld the diagonal brace between two pairs of diagonal locating plates respectively; the two positioning frames are arranged in parallel and opposite from top to bottom at a certain interval, at least two vertical supporting rods are welded between every two vertical and opposite horizontal connecting rods, and the axial leads of the two steel pipe pile jacks opposite from top to bottom are overlapped. The utility model is used for detain tower basis steel-pipe pile installation, can once only target in place the steel-pipe pile installation to can guarantee that the position accuracy and the straightness that hangs down of steel-pipe pile reach the design requirement.
Description
Technical Field
The utility model belongs to the technical field of the bridge construction, a arch rib erection construction that adopts the oblique pull to detain the method of hanging to carry out the arch bridge is related to, concretely relates to arch rib detains tower steel-pipe pile basis locating rack.
Background
The arch rib of the half-through steel box basket arch bridge is constructed by cable hoisting and cable-stayed buckling and hanging methods, the buckling tower is used as a main stress system for buckling and hanging the arch rib in an inclined pulling way, and the verticality of the buckling tower can directly influence the installation precision of the arch rib segment. The buckling tower is usually formed by assembling steel pipe members, and a tower foundation is a steel pipe pile foundation. The structure of steel pipe pile foundation is as shown in fig. 1, fig. 2, including 4 steel-pipe piles 6 that set up according to 4 summits of rectangle, because the construction position is located mountain area hard rock layer usually, the steel-pipe pile can't directly be inserted and beaten, excavate 4 stake holes 7 earlier in the mode of adopting artifical hole digging usually during the construction, then in going into stake hole 7 with 4 steel-pipe piles 6 hoists to it is fixed with the steel-pipe pile to pour concrete 8 between steel-pipe pile and stake hole inner wall. Because the diameter in stake hole is far greater than steel-pipe pile diameter, straightness and position accuracy are difficult to control in the stake downthehole during the steel-pipe pile, appear the deviation easily, although can adjust after the deviation appears, but the adjustment degree of difficulty is big, expends time for a long time.
Disclosure of Invention
The utility model aims at the above-mentioned problem, a tower steel pipe pile basis locating rack is buckled to arch rib is provided, guarantees the installation accuracy of tower footing steel pipe pile to improve the efficiency of construction.
The technical scheme of the utility model as follows:
the utility model provides a tower steel-pipe pile basis locating rack is detained to arch rib which characterized in that: the positioning device comprises two rectangular positioning frames, wherein each positioning frame comprises 4 positioning plates arranged according to 4 vertexes of a rectangle, a steel pipe pile jack is arranged in the middle of each positioning plate, 4 flat connecting rods are welded between the 4 positioning plates according to the edges of the rectangle, and diagonal brace rods are respectively welded between two pairs of diagonal positioning plates; the two positioning frames are arranged in parallel and opposite from top to bottom at a certain interval, at least two vertical supporting rods are welded between every two vertical and opposite horizontal connecting rods, and the axial leads of the two steel pipe pile jacks opposite from top to bottom are overlapped.
The utility model is used for detain tower basis steel-pipe pile installation, can once only target in place the steel-pipe pile installation to can guarantee that the position accuracy and the straightness that hangs down of steel-pipe pile reach the designing requirement, thereby guarantee to detain the straightness that hangs down of tower.

Detailed Description
As shown in fig. 3 and 4, the utility model comprises two rectangular positioning frames, each positioning frame comprises 4 positioning plates 1 arranged according to 4 vertexes of the rectangle, a steel pipe pile jack 2 is arranged in the middle of each positioning plate, 4 flat connecting rods 3 are welded between the 4 positioning plates according to the edges of the rectangle, and diagonal brace rods 4 are respectively welded between two pairs of diagonal positioning plates; the two positioning frames are arranged in parallel and opposite up and down at a certain interval, at least two vertical supporting rods 5 are welded between every two up-down opposite flat connecting rods, and the axial leads of the up-down opposite steel pipe pile insertion holes 2 are overlapped.
The utility model discloses during the concrete implementation, set up the interval of the steel-pipe pile jack on 4 locating plates according to 4 steel-pipe pile intervals of detaining the tower foundation, every steel-pipe pile jack equals the steel-pipe pile diameter of detaining the tower foundation, or is greater than the steel-pipe pile diameter of detaining the tower foundation and is no longer than 3mm.
As shown in fig. 4, the utility model discloses when using, support the below locating frame of locating rack and detain tower foundation position and transfer to the level, steel-pipe pile jack on 4 locating plates of below locating frame is respectively just to 4 stake holes, and 4 steel-pipe piles 6 that will detain the tower foundation insert the stake hole from the steel-pipe pile jack that the locating frame is relative from top to bottom respectively, can guarantee that 4 steel-pipe piles's straightness that hangs down and interval accord with the designing requirement. After concrete is poured into the pile hole to fix the steel pipe pile, the positioning frame is lifted away from the upper side by a crane, and the positioning frame can be repeatedly used.
