Description

A kind of jacking rectification structure

Technical field

The utility model belongs to the building inclination rectification field, relates in particular to building jacking rectification structure.

Background technology

Regulation according to " People's Republic of China's industry standard existing construction foundation underpin technical specification ", the jacking rectification is by the structure underpinning technology (or utilizing original structure) of steel concrete or masonry the basis of building to be separated along a certain certain location with superstructure, and employing steel concrete is reinforced, segmentation underpins, form totally enclosed jacking underpins beam (post) system.Because the jacking rectification is that a dynamic process and building itself are inclined again, under the active force and reaction force of jack-up construction, requires the integral jacking structure to have enough safety stocks and stability.The climbing structure of commonly using is made up of grade beam, grade beam embedded iron parts, cushion block, jack, lifting beam embedded iron parts, lifting beam, need with some overlapping being positioned on the grade beam embedded iron parts of cushion block according to top lifting height, jack places between cushion block and the lifting beam embedded iron parts.In the jacking process, between top lifting beam and the bottom grade beam only by jack and cushion block support and connection, and cushion block only relies on action of gravity to connect each other, it is all lower to reach integrally-built horizontal force resistant between the cushion block, less stable, when top lifting height was higher, the gravity skew easily took place so that collapse because of horizontal force action in cushion block, make jacking rectification process out of control and form the Important Project accident, therefore its maximum top lifting height of jacking rectification structure of commonly using is generally 80cm.

Summary of the invention

But the purpose of this utility model is to provide a kind of stable higher jacking rectification structure of horizontal force resistant.

For achieving the above object, the utility model mainly comprises grade beam, the grade beam embedded iron parts, cushion block, jack, the lifting beam embedded iron parts, lifting beam, cushion block is pressed overlapping placement from bottom to up according to the top lifting height needs by one or some and is formed, nethermost cushion block is locked on the grade beam embedded iron parts, jack is locked on the uppermost cushion block, the jacking plane of jack is locked on the lifting beam embedded iron parts, the wherein one side of the end face of cushion block and bottom surface forms slide slot, another side forms the slide bar vertical with slide slot, and this slide slot is suitable with the profile that slides bar.

After adopting this structure, between the adjacent pod can by slide slot with slide bar and link to each other, because the slide slot of cushion block end face and bottom surface is with to slide bar vertical mutually, therefore the placement direction of adjacent pod is vertical mutually, it is as a whole securely each cushion block to be linked to each other, and resists the horizontal force action of all directions, has increased the stability of this climbing structure, greatly improve the height of jacking rectification, avoided the generation of engineering accident.

For improving this stability of structure better, the utility model can be provided with the flexible jumper of some quantity between lifting beam and grade beam, but this flexible jumper is made up of upper and lower two parts that mutual cover merges relative displacement.Compare with located by prior art like this, this flexible jumper can extend with the jacking of lifting beam thereupon, thereby lifting beam and grade beam are connected as a single entity, and guarantees integrally-built stability in the jacking overall process, has improved anti-horizontal applied force.

The specific embodiment

See also shown in Figure 1, the utility model mainly comprises grade beam 1, grade beam embedded iron parts 11, cushion block 2, jack 3, lifting beam embedded iron parts 41, lifting beam 4, cushion block 2 is pressed overlapping placement from bottom to up according to the top lifting height needs by one or some and is formed, nethermost cushion block 21 is locked on the grade beam embedded iron parts 11, jack 3 is locked on the cushion block 22, and the jacking plane 31 of jack 3 is locked on the lifting beam embedded iron parts 41.As shown in Figure 2, the end face of cushion block 2 201 forms slide slots 203, and bottom surface 202 forms vertical with slide slot 203 bar 204 that slides, this slide slot 203 and to slide bar 204 suitable; Cushion block 2 also can be as shown in Figure 3, and its end face 201 forms and slides bar 204, and bottom surface 202 forms the slide slot 203 vertical with sliding bar 204, this slide bar 204 and slide slot 203 suitable.

After adopting this structure, between the adjacent pod 2 can by slide slot 203 with slide bar 204 and link to each other, because the slide slot 203 of cushion block 2 end faces 201 and bottom surface 202 is with to slide bar 204 mutual vertical, therefore the placement direction of adjacent pod 2 is vertical mutually, it is as a whole securely each cushion block 2 to be linked to each other, and resists the horizontal force action of all directions.

For making things convenient for cushion block to connect, and strengthen connective stability in construction, as shown in Figure 4, the slide slot 203 of cushion block 2 can be the dovetail type groove, slides bar 204 and is the dovetail type bar; Also can be as shown in Figure 5, the side of the slide slot 203 of cushion block 2 caves inward, and forms anti-hook, and it is suitable with slide slot 203 that it slides bar 204.

In addition,, cushion block 2 can be designed to square for making cushion block 2 active force each other bigger, like this when cushion block is mutually vertical when placing, its identical area unanimity; For increasing the active area of uppermost cushion block 22 and lifting beam 4, nethermost cushion block 21 and grade beam 1, can make the bottom surface 211 of nethermost cushion block 21 be the plane, the end face 221 of uppermost cushion block 22 is the plane.

For improving this stability of structure better, as shown in Figure 6, the utility model can be provided with the flexible jumper 5 of some quantity between lifting beam 4 and grade beam 1, this flexible jumper 5 is made up of outer tube 51 and inner sleeve 52, outer tube 51 is linked in outside the inner sleeve 52, its top 511 bores are slightly smaller than inner sleeve 52 bottoms 521 bores, and outer tube 51 bottoms 512 are locked on the grade beam 1, and inner sleeve 52 tops 522 are locked on the lifting beam 4.This flexible jumper 5 can extend with the jacking of lifting beam 4 thereupon, guarantees that lifting beam 4 fuses with grade beam 1 in the jacking overall process.

Reasonable for the distribution that makes this flexible jumper 5, its quantity can be consistent with the quantity of jack 3, and be positioned over the stressed node place of this jacking rectification structure.
