Description
Technical field
The present invention relates to a kind of butyl putty steel plate water-stopping rear pouring tape construction method.
Background technology
In monolithic reinforced concrete structure design and construction, because main building, attached building sedimentation are uneven, Chang Zhu, attached building handing-over
Place sets a 700~1000mm wide from basement bottom board to the late poured band of attached building roofing beam slab.Overlength reinforced concrete
Native frame structure is larger because transverse temperature, contraction etc. are deformed, between floors between set 700~1000mm the bottom of from
Layer to roofing beam slab late poured band.And the construction method of post-cast strip sealing is many at present, have in the biside plate of post-cast strip
Between set expansion sealing strip, have and set steel plate for sealing water in the middle of the biside plate of post-cast strip, have in being set in the middle of the biside plate of post-cast strip and bury
Formula waterstop, also have and add external labeling type waterstop again in the above-mentioned methods.But by Construction practices for many years, post-cast strip is oozed
Leak is always inevitable.
The content of the invention
Effectively post-cast strip percolating water is prevented it is an object of the invention to provide one kind, it is ensured that the butyl putty steel of construction quality
Plate water-stop post-pouring construction method.
The present invention technical solution be：
A kind of butyl putty steel plate water-stopping rear pouring tape construction method, it is characterized in that：Comprise the following steps：
（One）Line setting：Required according to construction drawing, every post-cast strip position of center line is first ejected on bottom cushion, and move outside
800mm is used as Construction control line；
（Two）External labeling type rubber water-proof belt construction：
A, fish tail and waterproof layer construction are finished, and concrete strength is reached after 1.2Mpa, and external labeling type rubber fastening band is layered on into post-cast strip
Both sides, it is desirable to tiled between two parties along post-cast strip sideline；
B, external labeling type rubber water-proof belt lacing method to set up：
（1）The connection of external labeling type rubber fastening band is using bonding；
（2）The lap of splice is not less than 30cm；
（3）Before bonding, the part that external labeling type rubber fastening band protrudes is sliced off with knife first, then with file by with the rubber being bonded
The bonding plane of glue waterstop files out fresh face, with acetone or gasoline cleaning bonding plane and deformation position cylindrical cavity inner chamber；
（4）Glue is uniformly smeared in bonding plane, after glue is air-dried, two pieces of external labeling type rubber fastening bands are bonded, after bonding
Beaten with rubber hammer, make bonding site comprehensive engagement as far as possible, at utmost reduce space, then with special fixture by clinch
Position is stepped up, and fixture is pulled down after 30 minutes；
（Three）Fast-easy closing-up net makes：
According to two layers of fast-easy closing-up net above and below the making of the thickness of sole plate and exterior wall, closing in network framework uses diameter 12mm steel
Muscle makes, and width=（Bottom plate and exterior wall thickness-levels reinforcing bar and protective layer thickness）/ 2, laterally press 500 spacing welded reinforcements
Ladder, outsourcing string diameter 1mm, 1.5 × 1.5mm of aperture dense mesh is firm with iron wire colligation；
（Four）Lower floor's fast-easy closing-up net construction：
Sole plate or outer wall formwork of basement side form are used after fast-easy closing-up net, sole plate bottom layer of the reinforcing steel colligation finish, will
Lower floor's fast-easy closing-up net is welded on sole plate reinforcing bar along post-cast strip both sides sideline point；
（Five）Butyl putty steel plate water stopper is installed
It is 2 ~ 3mm that the butyl putty steel plate water stopper, which includes both sides above and below the thick galvanized steel plain sheets of 0.4 ~ 0.6mm, galvanized steel plain sheet,
Thick rubber-isobutylene luting layer, rubber-isobutylene luting layer surface sets diaphragm；
After lower floor's fast-easy closing-up net firm welding, in its transverse weld 1500mm diameters 12mm one long suitable for reading reinforcing bar, spacing
500mm, is played a supportive role, and to prevent from, butyl putty steel plate water stopper is tiled between two parties along post-cast strip both sides sideline, both sides
Width is consistent；The processing of butyl putty steel plate water stopper joint, opens diaphragm, by butyl putty steel plate water stopper junction
100mm is overlapped, air is removed with hand pressure close-up and is bonded firmly by itself, and silk is rolled in reinforcing, and diaphragm is sticked again；Butyl putty steel
After plate waterstop is completed, a long 1500mm, diameter 12mm reinforcing bar, spacing 500mm is pressed to stop with butyl putty steel plate on top
Water band bottom surface reinforcing bar will compress waterstop by two reinforcing bars up and down in same position, will be upper on butyl putty steel plate water stopper both sides
Lower two reinforcement weldings firmly, prevent butyl putty steel plate water stopper from moving left and right；
（Six）Upper strata easily net construction soon
After the installation of butyl putty steel plate water stopper is fixed, on the transverse steel that upper strata fast-easy closing-up net is welded on to pressure waterstop,
Sole plate top bars colligation is carried out again；
（Seven）Bottom plate rear pouring tape top bars colligation；
（Eight）Tear the diaphragm on waterstop concrete placings side；
（Nine）Post-cast strip surface layer model sheetinstallat：
After the completion of sole plate and post-cast strip surfacing steel bar colligation, in post-cast strip both sides use 50mm × 100mm suitable for reading flitch
Tied with iron wire with reinforcing bar；
（Ten）Concreting：
（1）Poured after first time before the sole plate concreting of both sides, by casting concrete side butyl luting waterstop diaphragm
Remove, leave the half butyl luting waterstop diaphragm in post-cast strip；, should be from post-cast strip both sides when concrete will arrive post-cast strip
Uniform blanking, is symmetrically carried out when vibrating, and prevents expansion joint deformation, destruction；
（2）Post-cast strip concreting：Post-concreted expansion strip is 60 days after concreting, and pouring after settlement binds in agent structure
Pour within later 60 days；Before casting concrete, construction seam surface laitance and debris are cleaned out, butyl putty steel plate water-stopping is torn off
The diaphragm taken；During casting concrete, net slurry is first spread, 30~50mm thick 1 is repaved：1 cement mortar or painted concrete circle
Face inorganic agent and in time placing concrete, make linking new and old concrete firmly, to ensure the water-stagnating effect of steel plate water stopper.
As such as found in underplate concrete casting process, post-cast strip side fast-easy closing-up net or steel wire are fixed loosely, the number of plies
It is few, cause underplate concrete from side inflow advanced water-stop post-pouring zone, should be cleared up in time.
Easy construction of the present invention, strengthens waterproof effect at post-cast strip, improves construction quality, reduces engineering construction difficult
Degree, should be widely promoted；Butyl putty steel plate water-stopping post-cast strip has excellent water-fast, acid and alkali-resistance and ageing-resistant performance；Use
Long lifespan, and itself is nontoxic, it is environmentally safe.
With reference to embodiment, the invention will be further described.
