Description
Technical field
The utility model belongs to the stretching device technical field, relates in particular to a kind of novel non-leakage water without dust fall low noise stretching device.
Background technology
Need to install the shrinkage joint in the bridge construction.Current shrinkage joint all is equipped with the sealing adhesive tape no matter be type steel expansion joint, three anti-interdigitated electrode structure shrinkage joint or modular shrinkage joint.The sealing adhesive tape is installed trouble, in use easily damages.
The utility model content
It is simple that the technical problems to be solved in the utility model just provides a kind of installation, and cost is low, and the novel non-leakage water of long service life is without dust fall low noise stretching device.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: comprise the vertical force bearing plate of paired setting, the top of vertical force bearing plate is provided with the horizontal comb plate that is connected as a single entity with it, is provided with elastic body between the vertical force bearing plate of described paired setting.
Its additional technical feature is: described elastomeric end face and bottom surface all are the plane; Described elastomeric bottom surface is the plane, and end face is provided with the projection that is complementary with horizontal comb plate plate seam; Described elastomeric bottom surface is arch, and end face is the plane; Described elastomeric bottom surface is arch, and end face is provided with the projection that is complementary with horizontal comb plate plate seam; Described elastomeric thickness is 2---10 centimetres; Have through hole on the described elastic body.
Novel non-leakage water provided by the utility model without dust fall low noise stretching device compared with prior art is provided with elastic body between the vertical force bearing plate that arranges in pairs.Elastic body is the highly elastic materials such as polyurethane, during installation, liquid elastomer is cast in horizontal comb plate and vertical force bearing plate place, and being bonded as one with the medial surface of the bottom surface of horizontal comb plate and vertical force bearing plate after liquid elastomer solidifies gets final product, and installs very easy.Compare with the sealing adhesive tape, elastomeric seal is tight, and water resistance is good, does not retain rubbish, reduces noise, and cost is low, and long service life can be repaired after damage.As required, elastomeric end face and bottom surface all are that plane or elastomeric bottom surface are the plane, it is arch that end face is provided with the projection or the elastomeric bottom surface that are complementary with horizontal comb plate plate seam, end face is that plane or elastomeric bottom surface are arch, and end face is provided with the projection that is complementary with horizontal comb plate plate seam.And elastomeric thickness can be 2---10 centimetres.Have through hole at elastic body, telescopicing performance is better.
