Abstract
The utility model discloses a connecting structure between poured concrete waterstop and new poured concrete waterstop. The connecting structure comprises an expansion waterstop strip buried in a poured concrete seam and a rubber waterstop strip with one end needing to be buried in a new poured concrete seam, wherein grooves are formed in the surrounding of the expansion waterstop strip in the poured concrete along the burying direction of the expansion waterstop strip, the other end of the rubber waterstop strip is buried in the groove close to the expansion waterstop strip, the rest gaps in the grooves are sealed by polysulfide sealant, a polyethylene hole sealing plate is filled in a gap beyond the connecting part of the expansion waterstop strip and the rubber waterstop strip, and a polysulfide sealant coating is arranged on the surface located on the water side of the seam. The connecting structure disclosed by the utility model has the advantages of simple process and high construction speed, and the rubber waterstop strip and the expansion waterstop strip are buried in the grooves in the poured concrete through the polysulfide sealant so as to ensure a good waterstop effect at the connecting part of two different types of waterstops by means of the aging resistance and good airtightness of the polysulfide sealant.
Description
Technical field
The utility model relates to the syndeton between sealing, especially relates to the syndeton between a kind of sealing of concreting and young concrete sealing.
Background technology
Connection between concrete sealing at present all refers to the connection between same type sealing, but while being the situation of dissimilar sealing for the sealing in concreting and the sealing in young concrete, this just need to study a kind of new sealing syndeton and guarantee that two kinds of dissimilar sealings are at the good stagnant water effect of joining place.
Summary of the invention
The utility model object is to provide a kind of easy construction, the sealing of concreting that stagnant water effect is good and the syndeton between young concrete sealing.
For achieving the above object, the utility model can be taked following technical proposals:
Syndeton between the sealing of concreting described in the utility model and young concrete sealing, be included in the expansion sealing strip that concreting has buried in stitching and need to imbed the rubber fastening band in young concrete seam, expansion sealing strip surrounding in described concreting is imbedded direction along it and is offered groove, the adjacent expansion sealing strip in one end of described rubber fastening band is embedded in groove, in described groove, remaining space is closely knit by polysulfide sealant, filled polyethylene closed pore plate in seam beyond described expansion sealing strip and rubber fastening band joining place, at described seam, be positioned at side surface near water and be provided with polysulfide sealant coating.
The utility model advantage is that technique is simple, speed of application is fast, by polysulfide sealant, rubber fastening band is embedded in the groove in concreting in the lump together with expansion sealing strip, utilizes ageing-resistant, the low tenderness of polysulfide sealant to bend shape characteristic good, that tightness is good and guaranteed that two kinds of dissimilar sealings are at the good stagnant water effect of joining place.
Accompanying drawing explanation
Fig. 1 is the layout schematic diagram having stitched in concreting and young concrete in the utility model.
Fig. 2 is the A-A sectional structure schematic diagram of Fig. 1.
Fig. 3 is the B-B sectional structure schematic diagram of Fig. 2.
The specific embodiment
As shown in Figure 1, 2, 3, syndeton between the sealing of concreting described in the utility model and young concrete sealing, be included in the expansion sealing strip 2 that concreting 1 has buried in stitching and need to imbed the rubber fastening band 4 in young concrete 3 seams, expansion sealing strip 2 surroundings in described concreting 1 imbed along it groove 5 that direction is offered a 8cm * 15cm * 31cm, described 8cm is the width dimensions of parallel seam direction, and described 15cm imbeds the depth dimensions of direction along expansion sealing strip 2; Described 31cm is that each gos deep into the length dimension that 15cm adds the wide 1cm of seam along seam two side direction concreting 1; The adjacent expansion sealing strip 2 in one end of described rubber fastening band 4 is embedded in groove 5, closely knit by polysulfide sealant 6 in the interior remaining space of described groove 5; Filled polyethylene closed pore plate 7 in seam beyond described expansion sealing strip 2 and rubber fastening band 4 joining places, is further to guarantee stagnant water effect, at described seam, is positioned at the thick polysulfide sealant coating 9 of side 8 surface painting 5cm near water.
