Abstract
The utility model discloses a bridge deck traction limiting device. The limiting device is fixedly arranged on two sides of a bridge seam of the bridge deck and comprises two locating elements and a traction regulating element, the two locating elements are respectively fixed on the bridge deck of the two sides of the bridge seam, the traction regulating element is arranged between the two locating elements, and the two ends of the traction regulating element are respectively and fixedly connected with the locating elements. The limiting device can effectively play a role of traction and limitation of the bridge decks at two sides of the bridge seam by the two locating elements and the traction regulating element when the bridge lifts up and regulate the distance between the bridge seams by nuts so as to effectively reduce the horizontal projection length of a multi-span bridge under the condition of changeless bridge gradient direction. The utility model further has the advantages of high regulation precision and good safety performance.
Description
Technical field
The utility model relates to the spacing technology of bridge jacking, more particularly, relates to a kind of bridge floor tractive stopping means.
Background technology
In the bridge jacking process, when the gradient of whenever striding the beam body changed, this horizontal projection length of striding the beam body will change.If originally the gradient of beam body is a descending, when its gradient diminished after the jacking, this horizontal projection length of striding the beam body will be elongated, otherwise, as the same.If the horizontal projection length of multispan beam body changes, the horizontal projection length that then is superimposed changes will be very big, thereby totally unfavorable to bridge jacking.Therefore must in the jacking process, carry out spacing to bridge floor.At present, it is spacing to adopt the mode of steel strand to carry out tractive usually.It mainly to being fixed in the steel member of Liang Tishang, applies pulling force by steel strand, thereby carries out spacing and adjusting beam seam.Because under the effect of pulling force, steel strand easily produce deformation and fracture, have great potential safety hazard, and the precision of adjusting beam seam is also relatively poor.
The utility model content
At the above-mentioned shortcoming that exists in the prior art, the purpose of this utility model provides a kind of bridge floor tractive stopping means, and this stopping means can effectively play the effect that bridge floor is spacing and the beam seam is regulated when bridge jacking.
For achieving the above object, the utility model adopts following technical scheme:
This bridge floor tractive stopping means is fixed on the beam seam both sides of bridge floor, comprise positioning element and tractive adjusting parts, two positioning elements are separately fixed on the bridge floor of beam seam both sides, tractive is regulated parts and is located between two positioning elements, and the two ends of tractive adjusting parts are connected to a fixed with positioning element respectively.
Described positioning element comprises angle steel and stiffening rib, and the angle steel bottom is fixing with the reinforcing bar welding of mating formation on the bridge floor, and several stiffening ribs are welded on the angle steel respectively.
Described tractive is regulated parts and is comprised double threaded screw and nut, and corresponding angle steel is passed at the double threaded screw two ends respectively, and fastening by nut.
The quantity of described double threaded screw is several, is fixedly arranged on side by side between two angle steel.
In technique scheme, bridge floor tractive stopping means of the present utility model is fixed on the beam seam both sides of bridge floor, comprise positioning element and tractive adjusting parts, two positioning elements are separately fixed on the bridge floor of beam seam both sides, tractive is regulated parts and is located between two positioning elements, and the two ends of tractive adjusting parts are connected to a fixed with positioning element respectively.This stopping means is regulated the fastening of parts by two positioning elements and tractive, when bridge jacking, can effectively play the tractive position-limiting action between the bridge floor of beam seam both sides, and can regulate beam by nut and stitch distance, thereby under the constant condition of beam body gradient direction, effectively reduce the horizontal projection length of multispan beam body.This stopping means also has the precision of conciliation height, the advantage that security performance is good.
Description of drawings
Fig. 1 is the sectional view of the structure and the user mode of stopping means of the present utility model;
Fig. 2 is the vertical view of the user mode of stopping means of the present utility model.
The specific embodiment
Further specify the technical solution of the utility model below in conjunction with drawings and Examples.
Please in conjunction with Fig. 1, shown in Figure 2, the beam that bridge floor tractive stopping means 10 of the present utility model is fixed at bridge floor stitches (3 among Fig. 1 is bent cap) on 1 both sides, comprise positioning element and tractive adjusting parts, two positioning elements are separately fixed at beam and stitch on the bridge floor of 1 both sides, tractive is regulated parts and is located between two positioning elements, and the two ends of tractive adjusting parts are connected to a fixed with positioning element respectively.Wherein, positioning element can adopt angle steel 11 to make, and reinforcing bar 4 welding of mating formation on angle steel 11 bottoms and the bridge floor are fixing, and evenly welds several stiffening ribs 12 in the outside of angle steel 11, is used to strengthen the rigidity of angle steel 11, improves the intensity of whole stopping means 10.Tractive is regulated parts can adopt double threaded screw 13 and nut 14, several double threaded screws 13 are located between two angle steel 11 side by side, and corresponding angle steel 11 is passed at the two ends of each double threaded screw 13 respectively, and be fastened in angle steel 11 by nut 14, be connected and fixed being fixed on two angle steel 11 that beam stitches 1 both sides, thereby in the jacking process, play the spacing effect of bridge floor tractive.The quantity of double threaded screw 13 and rank can adopt corresponding configuration according to calculating the size that the bridge self gravitation produces sliding force.In addition, this stopping means 10 can also play the effect that beam stitches 1 size of regulating in the bridge jacking process, and concrete principle is as follows:
Before jacking, beam between the bridge beam body 2 stitches 1 when smaller, can be by unscrewing the length that nut 14 extends two screw rods between the nut 14, distance between two angle steel 11 is increased, because angle steel 11 welds mutually with deck paving reinforcing bar 4 respectively, thereby promote the displacement that beam body 2 limits bridge, increase the beam crack between the two curb girder bodies 2.
In the jacking process, bridge can shorten the length of screw rod by fastening nut 14 owing to the sliding force that longitudinal gradient produces, and two distances between the angle steel 11 are dwindled, and can spur the displacement that bridge comes restraint beam body 2, thereby dwindles the beam seam 1 between the two curb girder bodies 2.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
