Along with constantly applying of bridge jacking technology, occur that increasing curve bridge jacking and vertical supertronic rotate jacking, and the height of jacking is also increasing.Different from the Integral synchronous jacking of straight line bridge, except the horizontal force that variations in temperature, lifting-up support initial eccentricity etc. produce, curve bridge jacking and vertical supertronic rotate jacking can make the projected length of beam body change, cause in jacking process, lifting-up support can be made to produce horizontal movement, and displacement along with the increase of top lifting height and rotational angle can constantly accumulation, thus affect the safety of lifting-up support.
Utility model content
The purpose of this utility model is to provide a kind of horizontal movement releasing device, can reduce or during controlling bridge jacking because supertronic rotates the lifting-up support horizontal movement that jacking, temperature action etc. produce, ensure the safety of lifting-up support, in the safety, applicability of effective lift bridge beam jack lifting technique, serve important function, be worthy of promotion and application.
In order to achieve the above object, the utility model is achieved through the following technical solutions: a kind of horizontal movement releasing device, is arranged between lifting-up support and jack, and described lifting-up support is arranged on immediately below described jack, be characterized in, this horizontal movement releasing device comprises:
Steel plate, is arranged between described lifting-up support and jack;
Laminated rubber bearing, is arranged between described lifting-up support and steel plate; Wherein
The upper limb of described steel plate and the top cap of described jack inconsistent;
The lower edge of described laminated rubber bearing and the top of described lifting-up support inconsistent.
Described surface of steel plate has default surface roughness.
The planar dimension of described steel plate is greater than the top cap planar dimension of described jack.
The planar dimension of described laminated rubber bearing is less than the planar dimension of described steel plate and the planar dimension at lifting-up support top respectively.
A kind of horizontal movement releasing device of the utility model compared with prior art has the following advantages: can effectively reduce or control because supertronic rotates the lifting-up support horizontal movement of the generation such as jacking, temperature action during bridge jacking, guarantee jacking process safety be reliable; Apparatus structure is simple, easy and simple to handle, has larger practical value.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of a kind of horizontal movement releasing device of the utility model;
Fig. 2 is embodiment schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, by describing a preferably specific embodiment in detail, the utility model is further elaborated.
As shown in Figure 1, a kind of horizontal movement releasing device, be arranged between lifting-up support 101 and jack 102, described lifting-up support 101 is arranged on immediately below described jack 102, this horizontal movement releasing device comprises: steel plate 1031, and described steel plate 1031 is arranged between described lifting-up support 101 and jack 102; Laminated rubber bearing 1032, described laminated rubber bearing 1032 is arranged between described lifting-up support 101 and steel plate 1031; The upper limb of wherein said steel plate 1031 and the top cap 1021 of described jack inconsistent; The lower edge of described laminated rubber bearing and the top 1011 of described lifting-up support inconsistent, namely described steel plate 1031 and laminated rubber bearing 1032 are cascaded, co-operation.Lifting-up support 101, horizontal movement releasing device and jack 102 three, when construction and installation, must ensure to align in center.
In the present embodiment, described steel plate 1031 has default surface roughness on the surface, to ensure that this steel plate 1031 relative sliding does not occur with described laminated rubber bearing 1032 and jack 102 in jacking process.
In the present embodiment, the planar dimension of described steel plate 1031 is greater than the planar dimension of the top cap 1021 of described jack, and the strength and stiffness of steel plate 1031 should meet vertical power transmission requirement.
In the present embodiment, the planar dimension of described laminated rubber bearing 1032 is less than the planar dimension at the planar dimension of described steel plate 1031 and the top 1011 of lifting-up support respectively, and the intensity of laminated rubber bearing 1032 meets vertical power transmission requirement.
In the present embodiment, described laminated rubber bearing 1032 has pre-set shear rigidity, and laminated rubber bearing 1032 relative sliding does not occur with the top 1011 of lifting-up support in jacking process.
For above-mentioned horizontal movement releasing device, this example provides corresponding a kind of horizontal movement method for releasing, concrete reference diagram 2.
Before beginning jacking, first need the installation to horizontal movement releasing device, bottom the bridge 201 treating supertronic rotation jacking, distribution beam 202 has been installed; Lifting-up support 203 is set up immediately below distribution beam 202; Lifting-up support 203 arranges the laminated rubber bearing 2041 of horizontal movement releasing device 204; Laminated rubber bearing 2041 arranges the steel plate 2042 of horizontal movement releasing device 204; Steel plate 2042 arranges jack 205, wherein the center alignment of jack 205, steel plate 2042, laminated rubber bearing 2041 and lifting-up support 203.Build rear jack 205, horizontal movement releasing device 204 and lifting-up support 203 and form jacking unit.
