Description
Technical field
The utility model belongs to technical field of building construction, induces crack structure more particularly, to a kind of concrete.
Background technique
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 be completely the same with on-site actual situations, and site operation situation
Be not every time it is identical, basement side wall cracking is still very serious.
Existing " concrete design specification " is defined as indoor 30 meters to what Basement Concrete Structures stretched spacing, and outdoor 20
Rice, if while pour using post-cast strip section construction, using special prestress measure, take can be reduced 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 to 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
It covers, carries out a kind of way of antiseepage, water-proofing treatment.
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 to be arranged attractive joint, currently used attractive joint setting method is as follows: general
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,
Subsequent stay sets structural joint, and structural joint stays the depth set to be determined according to the width of wall, and material selects batten or hardness higher crowded
Mould plate, and the thickness of cover to reinforcement, subsequent casting concrete are reserved 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, bury middle buried water stop and completion).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 the probability and points leaked is more, and the later period is only capable of leading to after the completion of general concrete structure pours
It crosses general leakage grouting mode and carries out leak stopping processing.If the later period encounters the unfavorable factors such as ground shakiness, structure sediment, crack meeting
Further expand, leak it is more serious, it is extremely disadvantageous to the service life of underground structure, equally also to building surrounding enviroment
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.
