Description
Technical field
The utility model is related to building field, more particularly to a kind of basement high building is tied with annex intersection bottom deformation seam
Structure.
Background technology
Traditional basement high building is designed with annex junction using common deformation joint, i.e., between high building and annex
Connection is fully disconnected, so as to avoid generating cracks on floor slab because armored concrete is shunk.But when many overlength undergrounds are set
Into after such deformation joint, top high building separates with periphery basement and the soil body in each layer of basement and loses constraint, can be to tower
The stress of building part generates certain influence；Meanwhile for pure basement part, deformation joint can cause structure one side to have outside water
Soil pressure, opposite side then face sky, and so uneven horizontal force has then needed basement structure to undertake, uneven when basement is deeper
Hengshui soil pressure will generate larger internal force for pure underground structure to be influenced, and further influences structure design.And routinely under
The crackings such as room floor are mainly caused by tensile stress, and floor compression, shear stress generally will not caused by temperature change
Floor is caused to crack.
Utility model content
The purpose of the utility model is to overcome the defects of the prior art, cracked stress according to general basement cracks on floor slab
The basement high building and annex intersection bottom deformation seam that a kind of waterproof measure of performance offer is relatively strong, water-proof drainage is combined are tied
What the technical solution of structure, the basement high building and annex intersection bottom deformation crack structure was realized in：
A kind of basement high building and annex intersection bottom deformation crack structure, including deformation joint body, the deformation joint sheet
Body is located at the intersection of basement high building and annex, and the deformation joint body back side is sealed with sealing compound, and upstream face is provided with
Back-adhering waterstop, the deformation joint body interior be provided with can buried water stop in slip casting, be additionally provided with one of concave-convex folded sheet,
The bumps folded sheet is to be close to what is set with the structure sheaf on both sides, and the deformation joint is filled with water in intrinsic remaining gap
Cement mortar.
Further, the deformation joint body bottom portion is disposed with polymer cement waterproof paint layer, first of poly- ammonia
It is ester waterproof coating layer, waterproof reinforced layer, second polyurethane water-proof paint layer, cross-level press mold adhesive waterproof coil layer, levelling
Layer, pea gravel concreten bed course.
Further, the concave-convex folded sheet is formed for the double-deck profiled sheet being close to.
Further, the thickness of the profiled sheet of the concave-convex folded sheet is 1~3mm.
Further, the width of the deformation joint body is 20~50mm.
Further, the cement mortar of the filling is polymer cement mortar.
The beneficial effects of the utility model：
(1) the utility model provides the biting connecions deformation joint that concave-convex folded sheet is set in a kind of deformation joint, although to become
Shape is stitched, but actually deformation joint can transfer compression in addition to it cannot transfer the main tensile stress that floor is caused to crack
And shear stress, the compression can pass through sidewall of basement → pure basement floor → deformation joint → high building floor → high building knot
The path of structure is transferred and is shared, so that the stress performance of pure basement floor is further improved；Simultaneously because
Shear stress can be transferred, although basement structure is provided with deformation but still is able to the position of fixity as top turret structure, right
Overall structure stress performance is preferable.
(2) filled polymer cement mortar in deformation joint, polymer cement mortar have expansion, water-break after-contraction after water suction
Property, there is good adhesion strength, high elastic modulus, deformation joint is internally provided with buried water stop in twice, Neng Gouman
Sufficient deformation joint can also reach ne-leakage effect while going out sedimentation and deformation up and down and left and right dilatation.
(3) deformation joint uses the composite water-proof system of polyurethane water-proof paint+cross-level press mold adhesive waterproof coil, and
Increase by one of waterproof reinforced layer in deformation joint, waterproof effect is preferable.
