Abstract
The utility model relates to a transverse adjusting and limiting device. The transverse adjusting and limiting device comprises limiting columns, limiting steel plates, lifting jacks, fixing frameworks and anchor blocks. The transverse adjusting and limiting device is characterized in that the limiting columns are arranged before a beam body which needs jacking, a left limiting column and a right limiting column are arranged, the limiting steel plates are respectively arranged on opposite sides of the left limiting column and the right limiting column. The anchor blocks are arranged on the cross section of the beam body which needs jacking. One anchor block is arranged on the left and one anchor block is arranged on the right. The fixing frameworks are installed on the anchor blocks. The lifting jacks are installed in the fixing frameworks. The transverse adjusting and limiting device is specially used for bridge jacking engineering and solves problems of bad synchronism and inaccurate stress in the jacking process. The transverse adjusting and limiting device has the advantages of being simple in structure, adjustable, and stable in manipulation.
Description
Technical field
The utility model relates to the bridge jacking field of engineering technology, is specifically related to a kind of lateral adjustments stopping means.
Background technology
At present, because the needs of urban planning and development, many buildings, bridge etc. need reconstruction, and various jacking technology, shift technique develop rapidly, become the state-of-the-art method of science of protection building reconstruction.The bridge jacking technology is extensively applied in the bridge reconstruction engineering, and bridge reconstruction is had outstanding meaning: in the integrality of protection bridge superstructure, the height of lifting bridge both provided cost savings to satisfy the navigation requirement, had shortened the duration again.
In the work progress of jacking, when being installed, jack tends to occur vertical error, and the influence that is subjected to unfavorable factors such as objective environment, the process that bridge rises just horizontal movement can occur, thereby the poor synchronization that causes jacking, position inaccuracy and make stressed inaccurate.Situation is serious, even can cause serious accident, causes the construction failure, leads to irremediable loss.
Therefore, we need a kind of stopping means of regulating, in order in horizontal transverse direction the bridge horizontal departure is controlled in real time and regulated, thereby perfect the solve jacking poor synchronization, stressed problem such as inaccurate.
Summary of the invention
The purpose of this utility model provides a kind of lateral adjustments stopping means.
For overcoming the deficiencies in the prior art, realize above-mentioned purpose, the utility model is achieved in that a kind of lateral adjustments stopping means, comprising: limited post, spacing steel plate, jack, fixed frame, anchor block; Described limited post is placed in before the beam body of required jacking, two limited posts about being provided with, and spacing steel plate is installed on the opposite side of left and right sides limited post respectively; Described anchor block is installed on the cross section of required lifting beam body, about respectively arrange one, fixed frame is installed on the anchor block, jack is installed in the fixed frame.
Two anchor blocks are installed in the position of beam body about the utility model, and two jack end faces touch spacing steel plate about making just; Described limited post is trapezoidal, and is inboard perpendicular to ground, outside band gradient; Described fixed frame is i-beam structure; Described anchor block is trapezoidal bulk.
Advantage of the present utility model is: simple in structure, can regulate, control stable.

The specific embodiment
Embodiment below in conjunction with accompanying drawing is described in further detail the utility model:
As Fig. 1, Fig. 3 and shown in Figure 4, the utility model is a kind of lateral adjustments stopping means, comprising: limited post 1, spacing steel plate 2, jack 3, fixed frame 4, anchor block 5; Limited post 1 is placed in before the beam body of required jacking, two limited posts 1 about being provided with, and spacing steel plate 2 is installed on the opposite side of left and right sides limited post 1 respectively; Described anchor block 5 is installed on the cross section of required lifting beam body, about respectively arrange one, fixed frame 4 is installed on the anchor block 5, jack 3 is installed in the fixed frame 4.
As Fig. 2, Fig. 3 and shown in Figure 4, about two anchor blocks (5) be installed in the position of beam body, two jack (3) end face touches spacing steel plate (2) about making just; Described limited post (1) is trapezoidal, and is inboard perpendicular to ground, outside band gradient; Described fixed frame (4) is i-beam structure; Described anchor block (5) is trapezoidal bulk.
After installing, when the occurred level displacement in uphill process of beam body, then give two limited posts (1) by jack 3 and apply power, make the beam body return to the origin-location again.
A kind of lateral adjustments stopping means of the utility model is not limited to the above embodiments.Those skilled in the art make the change of unsubstantiality, all fall into protection domain of the present utility model.
