Abstract
The utility model provides a concrete joint waterstop device, includes a plurality of inflation stagnant water adhesive tape and a plurality of closed -cell foam board. A plurality of closed -cell foam boards link to each other and arrange, are equipped with inflation stagnant water adhesive tape between the adjacent closed -cell foam board. The closed -cell foam board top of the top is equipped with polyvinyl chloride cement gum layer. In the fixed seam that sets up between a concrete layer and the 2nd concrete layer of a plurality of closed -cell foam boards, a plurality of inflation stagnant water adhesive tape and polyvinyl chloride cement gum layer. A concrete layer is old concrete layer. The 2nd concrete layer is new concrete layer. The utility model discloses rational in infrastructure, the marine structure that the two -layer concrete of the old and new meets sets up the stagnant water.
Description
Technical field
This utility model relates to the construction joint in mass concrete, subsiding crack and other hydraulic structures needing to arrange water sealing structure.Particularly to arranging water sealing structure in New-old concrete connecting part, a kind of concrete joint water stop structure.
Background technology:
The hydraulic structure being made up of mass concrete, is typically provided with construction joint or subsiding crack.When having sealing requirement when between seam, sealing should be set.Traditional rubber water-proof or the way of metallic water stop, for being embedded in advance between newly-built xoncrete structure seam, play sealing effect.If but there is New-old concrete and connect when still needing to set seam sealing, then cannot realize pre-buried, installation difficulty.To this end, invention a kind of easy for installation, without pre-buried, be adapted to the water sealing structure of New-old concrete interface, there is good stagnant water effect.
Utility model content:
The technical problems to be solved in the utility model, it it is the sealing for two-layer concrete joint, take the sealing mode that PVC cement layer, expansion water-stop adhesive tape and closed-cell foam plate combine to meet the sealing of structural joint, and a kind of concrete joint water stop structure provided.
Employing technical scheme is:
A kind of concrete joint water stop structure, including multiple expansion water-stop adhesive tape and multiple closed-cell foam plate.
Technical points is:
Multiple closed-cell foam plate arranged end, are provided with expansion water-stop adhesive tape between adjacent closed-cell foam plate.
The closed-cell foam plate of the top is arranged over PVC cement layer.
Multiple closed-cell foam plates, multiple expansion water-stop adhesive tape and PVC cement layer are fixedly installed in the seam between the first concrete layer and the second concrete layer.
Expansion water-stop adhesive tape can be fixed on the first concrete layer by the first cement steel nail.
Closed-cell foam plate can be fixed on the first concrete layer by the second cement steel nail.
PVC cement layer is positioned at the first concrete layer and the second concrete layer seam the superiors.
First concrete layer is old concrete layer.Second concrete layer is novel concrete layer.
Newly, old concrete layer carries out sealing by PVC cement layer, closed-cell foam plate, expansion water-stop adhesive tape water-swellable.
When certain rubber dam need to carry out reinforcement to slope section, destroying the sealing between base plate and slope section structural joint during dismounting, if using rubber fastening band sealing, difficulty of construction is big, and stagnant water effect is poor.When the sealing mode using PVC cement layer, expansion water-stop adhesive tape and closed-cell foam plate to combine then can meet the sealing of structural joint.
Have an advantage in that:
This utility model is rational in infrastructure, and each component technology is the most ripe, and operation logic is simple, and the hydraulic structure that flexible operation, applicable New-old concrete connect arranges sealing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
A kind of concrete joint water stop structure, including multiple expansion water-stop adhesive tape 2 and multiple closed-cell foam plate 3.
Multiple closed-cell foam plate about 3 arranged end, are provided with expansion water-stop adhesive tape 2 between adjacent closed-cell foam plate 3.
The closed-cell foam plate 3 of the top is arranged over PVC cement layer 1.
Multiple closed-cell foam plates 3, multiple expansion water-stop adhesive tape 2 and PVC cement layer 1 are fixedly installed in the seam between the first concrete layer 5 and the second concrete layer 6.
Expansion water-stop adhesive tape 2 is fixed on the first concrete layer 5 by the first cement steel nail 4.
Closed-cell foam plate 3 is fixed on the first concrete layer 5 by the second cement steel nail.
PVC cement layer 1 is positioned at the first concrete layer 5 and the second concrete layer 6 seam the superiors.
First concrete layer 5 is old concrete layer.
Second concrete layer 6 is novel concrete layer.
PVC cement layer 1 is positioned at old concrete layer and the novel concrete layer seam the superiors.
First patch expansion water-stop adhesive tape 2 is on old concrete layer, then is anchored on old concrete layer with the first cement steel nail 4.Then patch closed-cell foam plate 3 is on old concrete layer, anchors on old concrete layer with the second cement steel nail.The closed-cell foam plate 3 being positioned at foot was arranged to the seam construction seam end, poured novel concrete layer, completes joints between fresh and old concrete water sealing structure and installs.
