Description
Technical field
When the utility model relates generally to a kind of bridge lifting, be used for eliminating fast the bracing or strutting arrangement that supports the gap, do not influence bridge force-bearing.
Background technology
In the maintenance of the reconstruction of road and bridge, it is inevitable that the increasing of the replacing of bearing and bridge floor transformed.Because it is at existing bridge that bridge pad replacing or bridge floor are increased, its constructure scheme is subjected to the influence of many factors, as headroom, substructure form etc. at the bottom of bridge construction type, span, section form, the beam, situation varies, and is difficult to provide unified job practices.The method of bearing replacement has many, is abound with cribbing method, steel nose girder method, saddle type support method etc. as traditional sleeper, and these methods need be on stable ground, and the support that building structure is very strong is placed heavy large-scale jack on support.Along with the development of hydraulic technique, the jacking ability of super book type jack is increasing, can satisfy the requirement of up to a hundred tons of weight, and body height is low, can directly be placed in the narrow space.Present most bridge lifting all adopts super book type jack, and also comparative maturity of the construction technology of this respect.
Because fast, safely and efficiently raising jack-up construction efficient and assurance bridge construction quality being had great significance of bridge jacking construction technology, therefore though adopt ultrathin jack can satisfy the requirement of the low and up to a hundred tons of weight of headroom at the bottom of the beam, but the bridge jacking height needs to adopt the construction method of falling the top application just can finish the bridge jacking process often because stroke is not enough.For example: headroom has only several centimeters bridge need be raised to tens centimeters or tens centimeters at the bottom of the beam, if do not build steel structure support in order to reduce expenses, just can only adopt super book type jack, and place it on the bridge pier under the bridge, finish the jacking of bridge by falling the method on top.Need on bridge pier, place lip block before switching jack, so that the beam that falls uses.Because the lip block at every place is different with the gap between the bridge bottom, generally in 1～10mm scope, traditional method is the employing manual method, just squeezes into the book steel plate with hammer and timber wedge is eliminated the gap.
Because present most bridge all adopts super book type jack to change bearing or increase bridge floor, caused and paid attention to how synchronization of jacking up, having despised the asynchronous of the construction method of falling the top also has bigger influence to bridge equally.Because there is following problem in the construction method of falling the top application: 1. because the cushion block at every place is different because of compress variation behind the beam that falls with backing plate, after repeatedly switching construction, the error of accumulation may cause bridge deflection or skew, seriously can cause the bridge construction unbalance stress, bring unsafe hidden danger for the structure of bridge; 2. because the job site need be with the cushion block material of a large amount of different-thickness, so the field operation workload is big, and the part material can only use once, causes waste; 3. in the man-hour of falling the top application, use hammer to squeeze into book steel plate and timber wedge, efficiency of construction is low; 4. can not guarantee to fall synchronous altitude behind the beam.So adopt this construction method of falling top application efficiency of construction low and cost is high.
The utility model content
When the problem that the utility model need solve provides a kind of bridge lifting, be used for eliminating fast the bracing or strutting arrangement that supports the gap, do not influence bridge force-bearing.
For solving the problems of the technologies described above, technical scheme that the utility model adopts is:
A kind ofly can eliminate the bracing or strutting arrangement in gap fast, comprise the base nut, its center is provided with the spiral push rod that is threaded, and the manual strand thick stick that is provided with by spiral push rod periphery rotates and makes described spiral push rod realize elevating function; Described spiral push rod connects the anti-bias load pressure head by the sphere dottle pin, and anti-bias load pressure head bottom is the sphere of projection, and there is the through hole of a band boss at the center, can slide along sphere; Described sphere dottle pin top is recessed sphere, and the bottom is the awl cylinder, and there is a through hole at the center; Described spiral push rod head periphery has 6 uniform blind holes, and centre bore is tubaeform, and there is the through hole of a band boss its underpart; Hanger is held in the both sides of described base nut.
Further, the described trapezoidal thread that is threaded to;
Further, described sphere dottle pin is a polytetrafluoroethylmaterial material.
The utility model becomes rotatablely moving of spiral push rod into the oscilaltion of anti-bias load pressure head and moves owing to utilize screw-drive mechanism, supports the gap thereby can eliminate fast and effectively; Sphere dottle pin wear-resisting and that sliding-frictional resistance is little is housed between spiral push rod head and anti-bias load pressure head, can reduces friction; The bottom design of anti-bias load pressure head is become sphere, can solve the uneven problem in bridge bottom.Though the support device structure that can eliminate the gap fast described in the utility model is simple, during operation and leicht fallen D/A.Volume is the helical rotation mechanism of φ 110 * 80mm, and heavily about 7 kilograms, adjustable height 30mm manually twists the long 200mm of thick stick, and pretightning force can reach 2000 kilograms, only needs the power of pulling with 12 kilograms, and supporting capacity can reach 100 tons.So easy to operate, the efficiency of construction height, supporting capacity is big, and, can use repeatedly, reduce construction cost greatly.
