Description
Technical field
The utility model relates to building jacking technology, more particularly, relates to a kind of building jacking system.
Background technology
In general building jacking process, building is due to the imbalance of horizontal force in horizontal direction, or break the horizontal equilibrium of forces of building under the impact of other external force, thus the skew in generation horizontal direction, if horizontal offset is too large, linking between support system may be caused to become unstable, thus destruction is produced and unstability to whole support system, therefore there is huge potential safety hazard.
As can be seen here, how effectively to eliminate the horizontal direction displacement produced in building jacking process, be that this area needs the problem that will solve badly.
Utility model content
For the above-mentioned shortcoming existed in prior art, the purpose of this utility model is to provide a kind of building jacking system, effectively can correct the horizontal direction side-play amount that building produces in jacking process, eliminate the impact that side-play amount produces, ensure the safe and reliable of jacking process.
For achieving the above object, the utility model adopts following technical scheme:
This building jacking system, comprise be arranged in distribution beam bottom building, be arranged in jack below distribution beam, the support system that jack bottom is located at by pad, also comprise: be located at the horizontal direction displacement deviation correcting device between distribution beam and jack, this deviation correcting device comprises upper junction plate, correction plate and lower connecting plate, upper junction plate is connected fastening with distribution beam, lower connecting plate is connected fastening with jack, correction plate is clapboard, its lozenges is down and jump a queue between upper and lower junction plate, and fastening by the bolt of upper and lower junction plate.
Described upper junction plate and the horizontal plane of lower connecting plate measure-alike, and suitable with the horizontal plane size of correction plate, and be greater than jack bottom size.
Described upper junction plate, lower connecting plate, correction plate all adopt steel plate to make.
Described upper junction plate, the thickness of lower connecting plate are all greater than 20mm.
Described support system comprises organizes supporting mechanism more, and often group supporting mechanism comprises the bracing members that several stacked pads are established, and adopts bolt, reinforce into steel truss structure between the bracing members that level is adjacent by connecting rod between neighbouring bracing members.
In technique scheme, building jacking system of the present utility model, by arranging horizontal direction displacement deviation correcting device between distribution beam and jack, when building is in jacking process, produce the skew of horizontal direction, then carry out by deviation correcting device wedge shape correction plate of jumping a queue, in order to change the verticality of jack, thus horizontal force controlled in formation horizontal direction, the horizontal force of skew is caused to apply reverse horizontal force to building, building is made to change its horizontal movement due to the change of horizontal force, finally reach rectifying effect, ensure the safe and reliable of jacking process.
Accompanying drawing explanation
Fig. 1 is the structural representation of building jacking system of the present utility model.
Detailed description of the invention
The technical solution of the utility model is further illustrated below in conjunction with drawings and Examples.
Shown in Fig. 1, what building jacking system of the present utility model was same as the prior art is, equally also comprise be arranged in distribution beam 1 bottom building, be arranged in jack 2 below distribution beam 1, the support system that jack 2 bottom is located at by pad, jack 2 piston is arranged downwards.Unlike, this jack-up system also comprises: be located at the horizontal direction displacement deviation correcting device between distribution beam 1 and jack 2, this deviation correcting device specifically comprises upper junction plate 3, correction plate 4 and lower connecting plate 5, upper junction plate 3 is connected fastening with distribution beam 1, lower connecting plate 5 is connected fastening with jack 2, correction plate 4 be clapboard, and its lozenges and jump a queue between upper and lower junction plate 3,5, and passes through the bolt of upper and lower junction plate 3,5 and fastening down.
As an embodiment, described upper junction plate 3 is measure-alike with the horizontal plane of lower connecting plate 5, and it is suitable with the horizontal plane size of correction plate 4, and be greater than jack 2 bottom size, thus guarantee that top lift passes to distribution beam 1 by deviation correcting device, described upper junction plate 3, lower connecting plate 5, correction plate 4 steel plate all can be adopted to make, and and the thickness of upper junction plate 3, lower connecting plate 5 can be determined according to upper load, be generally greater than 20mm.
As another embodiment, described support system comprises organizes supporting mechanism more, often organize supporting mechanism and comprise the bracing members 6 that several stacked pads are established and the steel top cap 7 be connected with jack 2 piston being located at bracing members 6 the top, adopt bolt between neighbouring bracing members 6, between the bracing members 6 that level is adjacent, reinforce into steel truss structure by connecting rod.
The raising method of this building jacking device, specifically comprises step:
A. bottom building, arrange several distribution beam 1;
B. below each distribution beam 1, all arrange jack 2, and carry out reverse jacking by jack 2;
C. after every jacking stroke, at jack 2 lower end cushioning one bracing members 6, upper and lower bracing members 6 is carried out bolt, and reinforces into steel truss structure by between bracing members 6 adjacent for level by connecting rod, thus ensure the steadiness of whole support system; In addition, in cushioning process, must ensure that bracing members 6 aligns with the center of jack 2, thus produce eccentric compression when preventing stressed.Wherein, jack 2, bracing members 6, steel top cap 7 can carry out size, the adjustment of model and optimization according to building load, the stressed size of system;
When D. producing the skew in horizontal direction in jacking process when building, by arranging horizontal direction displacement deviation correcting device between distribution beam 1 and jack 2, in order to change the verticality of jack 2, thus rectify a deviation to the horizontal-shift of building, concrete correction step is as follows:
D1. bottom distribution beam 1, a upper junction plate 3 is connected and fixed;
D2. a lower connecting plate 5 is connected and fixed in jack 2 upper end;
The correction plate 4 of a wedge shape of D3. jumping a queue between upper and lower junction plate 3,5, the lozenges of correction plate 4 is down, and fastening by the bolt between upper and lower junction plate 3,5.
Adopt building jacking system of the present utility model, under normal jacking state, when building does not produce the skew in horizontal direction, correction plate 4 of need not jumping a queue; When in jacking process, when building produces the skew of horizontal direction, then undertaken jumping a queue by deviation correcting device the correction plate 4 of wedge shape, in order to change the verticality of jack 2, thus horizontal force controlled in formation horizontal direction, cause the horizontal force of skew to apply reverse horizontal force to building, make building change its horizontal movement due to the change of horizontal force, finally reach rectifying effect.After correction completes, because building sets back, i.e. dismountable correction plate 4.
In sum, the scheme that the utility model provides is simple, on the basis not changing original jack-up system agent structure, effectively can rectify a deviation to the horizontal direction displacement of building, thus adjust the side-play amount of building in real time, eliminate the impact that side-play amount produces, effectively ensure the safe and reliable of jacking process.
Those of ordinary skill in the art will be appreciated that, above embodiment is only used to the utility model is described, and be not used as restriction of the present utility model, as long as in spirit of the present utility model, all will drop in Claims scope of the present utility model the change of the above embodiment, modification.
