Step S13 is vacated between the top tray beam 6 and lower tray beam 7 after the upper wall body structure 1 jacking Rubber support 10 is set in second space, wherein above and below the top surface of the rubber support 10 and the bottom surface of the top tray beam 6 Relatively, the bottom surface of the rubber support 10 is contacted with the top surface of the lower tray beam 7, and rubber support is checked using level 10 gradient;

Step S14 recycles each jack 9, by 1 dropping place of upper wall body structure to predetermined absolute altitude.

Here, the subsequent acceleration transducer that can be used moves the existing sinking old building after upper wall body structure dropping place Force characteristic test guarantees that building key parameter is consistent with calculated result;When there is inconsistency, the specification of rubber support is adjusted, really Protect its isolating affection and stress performance.And the sedimentation and displacement of rubber support are observed, it adjusts in time.It finally can successively remove very heavy Top and sandwich wall Liang Dun.

Present invention employs jack jacking and the technologies of setting rubber support, propose collection strengthening of foundation, integral jacking And shock insulation solves control large area existing building integral jacking synchronism in the reconstruction of existing building arrangement and method for construction of one Technical problem has advanced and economy.

In one embodiment of construction method of the synchronous lifting of existing sinking old building of the invention and isolation structure, in top wall Top tray beam 6 is set on the bottom surface of body structure 1, in the top surface of the cushion cap 5 setting lower tray beam 7,

The first fixing steel plate 61 is buried in the bottom surface of the top tray beam 6, in the top surface of the lower tray beam 7 embedded second Fixing steel plate 71;

Here, the concrete parts smash on the basis of upper wall body structure and lower part bar shaped can be poured, by concrete from first, By manually shoveling into using minor diameter vibrator vibration compacting, in concrete initial set in second fixing steel plate and template edge gap Before using the flatness of level amendment fixing steel plate, finally surface concrete is smoothed out, fixing steel plate is permanently secured to, In lower coagulation pallet beam;

Step S13 is vacated between the top tray beam 6 and lower tray beam 7 after the upper wall body structure 1 jacking In second space in setting rubber support 10,

The top surface of the rubber support 10 and about 61 first fixing steel plate is opposite, by the rubber support 10 Bottom surface is contacted with second fixing steel plate 71.

In one embodiment of construction method of the synchronous lifting of existing sinking old building of the invention and isolation structure, step S8, In the two sidewalls of the top tray beam 6 and the lower part two sidewalls setting sandwich wall beam pier 8 of upper wall body structure,

In pre-buried first fixation steel plate in bottom surface of the sandwich wall beam pier 8, in the fixed steel in the top surface of the cushion cap 5 pre-buried second Plate, wherein first fixation steel plate and second fixation steel plate is opposite up and down;

Step S9, in the two sides setting steel structure support 11 to position of the jack 9,

The top of the steel structure support 11 and first fixation steel plate are connected and fixed, the steel structure support 11 Bottom is connected and fixed with second fixation steel plate;

Step S10 is installed in the jack 9 in the position,

The top surface of the jack 9 is contacted with first fixation steel plate, by the bottom surface of the jack and described the The contact of two fixation steel plates.

In one embodiment of construction method of the synchronous lifting of existing sinking old building of the invention and isolation structure, according to calculating Obtained anti-seismic performance determines the parameters of rubber support 10, comprising:

Every layer of rubber layer, interlayer of steel plate, the first steel plate envelope of rubber support 10 are determined according to the anti-seismic performance being calculated Thickness, the diameter of layer, the second steel plate sealing steel plate;

Step S13 is vacated between the top tray beam 8 and lower tray beam 7 after the upper wall body structure 1 jacking In second space before setting rubber support 10, further includes:

Every layer of rubber layer of rubber support 10, the thickness of interlayer of steel plate, diameter are determined according to the anti-seismic performance being calculated Interval stacking fixed rubber layer and interlayer of steel plate;

The first steel plate sealing 101, the second steel plate sealing steel plate of rubber support are determined according to the anti-seismic performance being calculated 102 thickness, diameter fix the first steel plate sealing 101 in the upper surface of the rubber layer of top layer, in the following table of the rubber layer of bottom The second steel plate sealing 102 is fixed in face, to obtain the rubber support 10;

In the second space vacated between the top tray beam and lower tray beam after upper wall body structure jacking It is arranged in rubber support,

First steel plate sealing 101 of the rubber support is opposite with about 61 first fixing steel plate, by the rubber Second steel plate sealing 102 of glue support 10 is contacted with second fixing steel plate 71.

Here, in the top surface assembling reinforcement mesh sheet 12 of upper wall body structure upper bottom surface and lower part strip footing, and will be multiple Foundation bolt and reinforced mesh 12 are bound securely, and cover top nut;First, second fixing steel plate is set by circular hole across bolt In top, and cover another nut;By the central axes of the first, second fixing steel plate alignment upper wall body structure, school is carried out after fixed Just.

In one embodiment of construction method of the synchronous lifting of existing sinking old building of the invention and isolation structure, by the rubber First steel plate sealing 101 of glue support 10 is opposite with about 61 first fixing steel plate, by the second of the rubber support 10 After steel plate sealing 102 is contacted with second fixing steel plate 71, further includes:

The first steel plate sealing 101 is connect admittedly with first fixing steel plate 61 by the first bolt, the first nut It is fixed;

The second steel plate sealing 102 is connect admittedly with second fixing steel plate 71 by the second bolt, the second nut It is fixed.

Here, rubber support can be installed after the concrete curing of upper and lower pallet beam;By the quadrangle of the second steel plate sealing It across foundation bolt, is tightened using nut, the second steel plate sealing and second fixing steel plate is passed through into the second spiral shell Bolt, the second nut are connected and fixed;Foundation bolt is passed through into first steel plate sealing quadrangle, is fallen after rise to existing sinking old building to predetermined After absolute altitude, fastening nut connects the first steel plate sealing and first fixing steel plate by the first bolt, the first nut Connect fixation.

Each embodiment in this specification is described in a progressive manner, the highlights of each of the examples are with other The difference of embodiment, the same or similar parts in each embodiment may refer to each other.

Obviously, those skilled in the art can carry out various modification and variations without departing from spirit of the invention to invention And range.If in this way, these modifications and changes of the present invention belong to the claims in the present invention and its equivalent technologies range it Interior, then the invention is also intended to include including these modification and variations.
