Description
Technical field
The invention belongs to technical field of building construction, and crack structure and its construction are induced more particularly, to a kind of concrete
Method.
Background technology
There is crack and is inevitable in concrete structure, although all shrinking coagulation using compensation in most of engineerings at present
Soil, but the ideal model due to being related to and state can not possibly be completely the same with on-site actual situations, and site operation situation
It is not every time identical, basement side wall cracking is still very serious.
It is existing《Concrete design specification》It is defined as indoor 30 meters to what Basement Concrete Structures stretched spacing, outdoor 20
Rice, if while pour using post-cast strip section construction, using special prestress measure, take can reduce concrete temperature become
The measure changed or shunk, is such as well grounded and responsible measures, the maximum spacing at expansion joint can suitably increase.In addition, in provision
Also there is explanation in explanation：Setting control seam can also be used to adjust the measure of flexible spacing wall.Control seam is to build
The stitch of object, panel, recessed foot etc. guide shrinkage joint to occur by the methods of pre-buried lath, and are subject in architectural construction processing
Cover, carry out antiseepage, water-proofing treatment a kind of way.
For major part basement considerably beyond the place of specification defined, common way is setting post-cast strip at present.On ground
When lower room side wall concrete pours, also with good grounds to need that attractive joint is arranged, currently used attractive joint setting method is as follows：Generally
Flexible middle buried water stop is selected, waterstop is first installed, then carry out reinforcing bar binding, and carry out the fixing process of waterstop,
Follow-up stay sets structural joint, and structural joint stays the depth set to be determined according to the width of wall, and material selection batten or hardness are higher crowded
Mould plate, and reserve the thickness of cover to reinforcement, follow-up casting concrete on material both sides.Equally in Construction of Urban Rail Traffic
In, it is also desirable to attractive joint is set, although section construction, continuous placing, also tends to only be arranged under long length sometimes
A small number of guide slits (generally directly being carried out according to the way of external wall construction seam, buried water stop and completion in burying).But it is such
Method is dealt with improperly, is easy so that crack is carried out along side wall toward top plate so that post-processing is more troublesome.
In conclusion after the completion of general concrete structure pours, the probability and points leaked is more, and the later stage is only capable of leading to
It crosses general leakage grouting mode and carries out leak stopping processing.If the later stage encounters the unfavorable factors such as ground shakiness, structure sediment, crack meeting
It further expands, leakage is more serious, extremely disadvantageous to the service life of underground structure, equally to having built surrounding enviroment also
It influences.And general common grouting for water plugging measure is only to control calibration method, and leakage problems cannot be really solved from source.
Invention content
The purpose of the present invention is, in the attractive joint of setting, easily cause attractive joint exhibition for existing ultra-long concrete building
Evolution provides a kind of concrete induction crack structure, promotes being given birth to along its setting position and length for attractive joint to uncontrollable situation
