Abstract
The utility model discloses a bridge jacking transverse limiting device which comprises a perpendicular truss and a horizontal support. The horizontal support is arranged on the perpendicular truss. The bridge jacking transverse limiting device is simple in structure, reasonable in design, convenient to use, practical and capable of effectively limiting the transverse horizontal displacement of a bridge body in the process of bridge jacking.
Description
Technical field
The utility model belongs to bridge jacking construction auxiliary equipment technical field, particularly relates to a kind of horizontal limit devices for bridge jacking.
Background technology
In bridge construction by swing, when bridge is carried out lifting operation, because the horizontal projection of bridge rotation construction beam body can be elongated, the beam body can cause the beam body to change because expanding with heat and contract with cold simultaneously, then jack-up system can produce relative transverse horizontal slippage with beam slab, particularly at the abutment position of top lifting height maximum, for guaranteeing the in the case safety of jack-up system and the structural safety of beam slab, horizontal limit devices need be set.
How to design a kind of simple in structure, practical horizontal limit devices and become this those skilled in the art's problem demanding prompt solution.
The utility model content
The purpose of this utility model is exactly the problem for above-mentioned prior art, and a kind of simple and practical bridge jacking horizontal limit devices is provided, and can solve the problems of the technologies described above fully.
The purpose of this utility model realizes by following technical proposals:
A kind of bridge jacking horizontal limit devices comprises vertical truss and horizontal stand, and horizontal stand is arranged on the vertical truss.
Further, described vertical truss is rectangular frame structure, mainly comprises vertical rod, push rod, cross bar, brace and junction plate, and two vertical rods be arranged in parallel, and the top connects by push rod, and the fixed junction plate in bottom connects some cross bars and brace between two vertical rods.
Further, be provided with stiffener between described vertical rod and the junction plate.
Further, described horizontal stand comprises main strut, tranverse connecting rod and diagonal control arm, and two main strut horizontal parallel arrange, between be connected with diagonal control arm by tranverse connecting rod.
Further, described main strut both sides are provided with angle steel.
The beneficial effects of the utility model are: simple in structure, reasonable in design, convenient and practical, and the effective transverse horizontal displacement of restraint beam body in the bridge jacking process.

The specific embodiment
Below in conjunction with specific embodiments and the drawings the utility model is further described.
Extremely shown in Figure 7 such as Fig. 1, a kind of bridge jacking horizontal limit devices, comprise vertical truss and horizontal stand, described vertical truss is rectangular frame structure, mainly comprises vertical rod 1, push rod 2, cross bar 3, brace 4 and junction plate 5, two vertical rods 1 be arranged in parallel, the top connects by push rod 2, and the fixed junction plate 5 in bottom connects some cross bars 3 and brace 4 between two vertical rods 1, and per two braces 4 are arranged in a crossed manner, are provided with stiffener 7 between vertical rod 1 and junction plate 5.
As shown in Figure 3, described horizontal stand comprises main strut 8, tranverse connecting rod 9 and the 8 horizontal parallel settings of 10, two main struts of diagonal control arm, is connected in the vertical rod 1 of vertical truss, are connected connection with diagonal control arm by tranverse connecting rod 9 between two main struts 8, and every main strut 8 bilateral symmetry are provided with angle steel 11.
4, one of two braces arranged in a crossed manner are elongated on the vertical truss, separated and gusset plate 6 full welds welding in another root, weld bead height 8mm.Vertical rod such as need spreading, contact need adopt the steel plate joint welding during spreading, namely at spreading position joint welding one block plate.
Above-mentioned vertical rod 1 is H shaped steel, and push rod 2, cross bar 3 and brace 4 are channel-section steel; Main strut 8 is H shaped steel, and the angle steel 11 of main strut 8 both sides is equal leg angle, and tranverse connecting rod 9 and diagonal control arm 10 are channel-section steel.
Extremely shown in Figure 7 such as Fig. 4, bridge is in using jack-up system jacking process, the vertical rod 1 of vertical truss is supported 17 per two meters height drawknot one connecting rods 18 with the jacking steel of jack-up system, the junction plate 5 of vertical truss bottom is connected and fixed by chemical anchor bolts 13 and abutment cushion cap 15, angle steel 11 on the horizontal stand on the main strut 8 is welded and fixed with bridge deck structure 16, thus the transverse horizontal displacement of restraint beam body.
Also can adopt crab-bolt that angle steel 11 and bridge deck structure 16 are linked together.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
