Description
Technical field
The utility model is related to the realm of building construction, more particularly to a kind of overhanging type unilateral side wall mixed reinforcement and displacement knot
Structure.
Background technology
Protect architectural structure system mainly based on brick mix structure at this stage, conventional existing building basis construction of replacing in situ
Method has grouting and reinforcing method, beams bearing wall, pile foundation or pier base method for strengthening etc..
Wherein, foundation grouting method reinforcing can effectively enhance bearing capacity of foundation slab, improve supporting course stress performance, but to ground
The disturbance of soil is larger, does not improve original base bearing capacity, limited to the increased Reconstruction Project applicability of working load, and by
Grouting process, soil body type and grouting serous fluid are affected, and directly affect the development of next process, influence the construction period.
Beams bearing wall is will to lift wall beam to be combined to form sandwich wall beam basis with bilateral ground beam, and the technical construction is simple, construction
Convenient, the foundation bearing capacity after displacement is safe and reliable, but lift wall beam passes through existing structure and easily causes influence to appearance facade；Ground
Beam rigidity and force request are relatively high, are generally required to ground beam lower part and put setting steady pressed anchor pile spaced apart or low pile frame
Cast-in-situ bored pile carries out pile foundation reinforcement；Pile foundation construction need to be by special equipment dead weight and counterweight, counter-force branch is done with newly-increased ground beam
It holds a little, counterweight and piling can cause initial settlement to injure, and foundation deformation can locally be sprung back after construction, and original basis is caused to disturb
Dynamic big, entire sequence of construction is relative complex, and the duration is also longer, and requirement of the pile foundation operation to construction site is bigger.
Pile foundation or pier base method for strengthening meet ground bearing capacity requirement with pile soil common action.It is most common at present
Pile foundation form be steady pressed anchor pile (precast concrete square pile or the hand hammer stake of prefabricated pipe bottom), can ensure basic globality and effectively
Control settlement, but its soil compaction effect is more apparent, and piling degree control difficulty is big；Prefabricated pile marches into the arena and needs a large amount of fields in advance
Ground, pile foundation construction continuity is difficult to ensure in narrow place；Pre-buried counterforce device in advance is needed, causes construction period stake position to lay and adjusts
Whole more difficult and pile foundation construction is limited by counter-force point maintenance progress, of high cost and long construction period.
Therefore, for above-mentioned pile foundation or pier base reinforcement means in duration, place, environmental protection, stress performance, soil disturbance
Etc. existing for it is insufficient, how one kind bearing capacity during place confined area ensures existing wall reconstruction is provided
The preferable reinforcing of control and replacing structure, become the art technical barrier urgently to be resolved hurrily.

Compared with prior art, overhanging type unilateral side wall mixed reinforcement and replacing structure provided by the utility model have such as
Lower advantage：
1, the structure of the utility model considers the segmentation again of inner space after horizontal structure separation, existing wall conduct
Building blocks of function is retained, and its underpart basis only undertakes the load that wall dead weight is transmitted without undertaking horizontal floor after transformation, then
The characteristic of the independence and original base consolidation and sclerosis of existing wall can be given full play to；
2, the inside that only (inside and outside newly-increased base join domain) will be connected with existing wall ground beam at newly-increased buttress position
Base extends in existing wall that no less than 500mm carries out the old and new's base configuration connection, forms point type build-in connection type, and
Buttress is symmetrical set pile foundation, it is ensured that newly-increased structural load is all transferred on newly-increased basis, is reduced to existing wall
Disturbance, make its dead weight that can uniformly transfer to original base；
3, traditional steady pressed anchor pile is replaced with tube bottom hand hammer stake, the hammering of stake bottom is carried out in place in steel pipe by hand hammer, no
Counterforce device need to be designed, Active workings demand is small；
4, stake is long more flexible with pile layout, and pile foundation construction is no longer limited by grade beam speed of application, thus can accelerate
Speed of application realizes low vibration, low noise environmental protection operation in addition, after tube bottom back cover plate adds buffer layer；
5, cancel lift wall-beam design on a large scale, the longitudinal strip foundation of buttress position setting only on the inside of existing wall
Material is greatly saved in beam, reduces construction cost.
