Description

Basement post-pouring zone waterproof construction
Technical field
Buildings waterproof construction applications are the utility model is related to, more particularly to a kind of basement post-pouring zone waterproof construction.
Background technology
Basement refers to that room floors exceed the half of the stud less than the height of outdoor ground level.Multilayer and high level Building needs deeper basis, using this height, basement to be built under architecture bottom layer, can both be increased using face Product, can save backfill under main building, relatively inexpensive practicality again.
It is to prevent monolithic reinforced concrete structure because autogenous shrinkage is uneven or settles not in construction that post-cast strip, which is, Issuable harmful cracks, according to design or job specfication requirement, stay what is set to face in sole plate, wall, beam relevant position When construction joint, if structure is temporarily divided into stem portion by post-cast strip, shunk by component inside, poured again after some time and smash this Construction joint concrete, structure is linked to be to overall area.
And Construction Later Casting Zone is generally set in big basement, but seepage point when post-cast strip is often made with, it is existing to do Method is usually that additional waterproofing layer is set up in the side that borders on the river of post-cast strip, but this way have ignored at the construction joint of post-cast strip both sides The problem of concrete self-waterproof is short of.
Utility model content
The purpose of this utility model is to provide a kind of basement post-pouring zone waterproof construction, its have can increase post-cast strip two At the construction joint of side the advantages of concrete self-waterproof performance.
Above-mentioned technical purpose of the present utility model technical scheme is that:
A kind of basement post-pouring zone waterproof construction, including underlayment, basement wall and post-cast strip body, the post-cast strip Construction joint is provided between body and basement wall, construction joint is obliquely installed towards basement wall and forms depression, construction The waterproof case for being used for increasing construction joint water resistance is provided with seam, waterproof case includes setting parallel to horizontal plane and positioned at depression The steel plate water stopper of apex, the expanded metal lath of filling and Construction of Supporting seam and the water expandable waterstop being embedded in construction joint.
By using above-mentioned technical proposal, construction joint is obliquely installed towards wall, is applied relative to what vertical level was set For work seam, construction joint is obliquely installed the amount that can reduce the water of surrounding into construction joint, then can enter one by waterproof case The water resistance of step increase construction joint, so as to avoid construction joint from being corroded by compared with juicy, the setting of expanded metal lath improves whole The intensity of individual construction joint, while the loss of post-cast strip concrete in construction can be avoided, steel plate water stopper, which penetrates, is arranged on ground In lower room wall and post-cast strip body, construction joint is divided into two sections, steel plate will not seep water completely, therefore can greatly promote Self waterproofing performance at the construction joint of post-cast strip both sides, water expandable waterstop can provide more protections for construction joint, enter one Step avoids underlayment and post-cast strip from being corroded by moisture.
Further set:The thickness of the steel plate water stopper is 4mm, width 300mm, and it is close to post-cast strip body and ground The both sides of lower room wall bend towards underlayment side and form flanging.
By using above-mentioned technical proposal, the thickness of steel plate water stopper need not be excessive, therefore it is arranged to 4mm and just can Meet to require, width is that 300mm can just cover whole construction joint, and so as to prevent moisture penetration, and steel plate water stopper is bent Forming flanging can make whole steel plate water stopper embedded more deep, improve the fastness of connection.
Further set:The flanging end is fixed with some connection reinforcing bars, and connection reinforcing bar is embedded in post-cast strip respectively In body and basement wall, and set in hook.
By using above-mentioned technical proposal, steel plate water stopper integrally can be more securely fixed in underground by connection reinforcing bar In room wall and post-cast strip body, it is fixed when setting in hook and can facilitate operating personnel's casting concrete for it.
Further set:The expanded metal lath is fixed on basement wall body sidewall by concrete, is set in the body of post-cast strip There is holding tank, water expandable waterstop is placed in holding tank, and is contradicted to expanded metal lath.
By using above-mentioned technical proposal, water expandable waterstop can produce 2-3 times of dilatancy after water is met, and fill All irregular surfaces, hole and the gap of full seam, while huge contact is produced, thoroughly prevent seepage, therefore one Seepage is produced in denier construction joint, rainwater expansion sealing strip can also keep off the water resistance of seepage.
Further set:Extruded polystyrene board is provided between the post-cast strip body and underlayment and concrete layer is shunk in compensation, and Fixed by some high-strength bolts.
By using above-mentioned technical proposal, extruded polystyrene board have excellent, lasting heat-insulation and heat-preservation, superior water resistant, Moisture resistance and anticorrosion, property durable in use, it can further lift the overall water resistance in post-cast strip.
Further set:Some baseplate reinforcing bars being mutually perpendicular in netted setting, bottom are provided with the basement wall body Slab muscle penetrates construction joint and extended in the body of post-cast strip.
By using above-mentioned technical proposal, as the supporting mechanism of whole basement, baseplate reinforcing bar is mutually perpendicular in netted Set, and basement wall and post-cast strip body are concatenated, make basement wall more firm.
Preferably, buried rubber fastening band in being provided with the underlayment of the post-cast strip body position.
By using above-mentioned technical proposal, in buried rubber fastening band be that one kind is mainly used in deformed concrete crack, stretched The waterstop product that the inside concretes such as contracting seam are set, have and stretched with elastomeric material elasticity and structure type to adapt to concrete The ability of deformation, underlayment seepage can be effectively prevented, and play a part of damping, buffering, extend the life-span of building.
In summary, the utility model has the advantages that:
The self waterproofing performance at the construction joint of post-cast strip both sides can be greatly promoted, water expandable waterstop can be construction joint More protections are provided, further avoids underlayment and post-cast strip from being corroded by moisture, effectively can also prevent underlayment from oozing Leakage, and play a part of damping, buffering, extend the life-span of building.
