Abstract
The utility model provides a shallow layer bridge expansion joint. The utility model comprises an anchoring assembly and two section steel, wherein, the two section steel is symmetrically arranged in the anchoring assembly and comprises a seal chamber, the shape of a cross section of the section steel is F-shaped, and the two section steel can bear the weight of automobile wheels and can correspondingly displace, and both ends of a rubber seal band are respectively and tightly arranged in the seal chamber of the two section steel. The utility model has the advantages of reasonable structure, low cost, high safety, stable running of automobiles, good waterproofing tightness and long service life.
Description
The utility model relates to a kind of shallow-layer bridge expanssion joint that the shallow-layer bridge is sewed on that is used for.
Being used for board-like rubber stretching device on the shallow-layer bridge expanssion joint at present is to make a concave pit on shallow soil, places steel plate again after placing rubber seal on the concave pit, and retractility is poor, and sealing effectiveness is bad, and water resistance is poor, and rubber is easily aging, and application life is short.
In view of above reason, the purpose of this utility model is in order to provide a kind of rational in infrastructure, safe and reliable, good sealing effect, and water resistance is good, the shallow-layer bridge expanssion joint of long service life.
The purpose of this utility model is achieved like this: anchoring assembly is arranged in the utility model, symmetry be loaded on the shape of cross section that contains annular seal space in the anchoring assembly for " F " but two shaped steel of the born truck wheel weight of shape and relative displacement, the two ends of rubber seal tape are tightly packed in respectively in the annular seal space on two shaped steel (referring to Fig. 1, Fig. 2), can adopt the general shallow pre-buried anchoring assembly in present market, rigidity anchoring assembly as anchor plate and weldering annular anchor bar composition thereon also can adopt the WELDING STUDS anchoring of socket cap or jag shape peg.
The shape of cross section of above-mentioned rubber seal tape is " V " shape (referring to Fig. 1, Fig. 2), expands with heat and contract with cold, water resistance is good, and sealing effectiveness is good.
Compare with existing board-like rubber stretching device, the utlity model has following advantage:
1, the closely connected rubber seal tape that higher-strength, elasticity and ageing-resistant performance are arranged has reliable sealing performance in the annular seal space on " F " shaped steel, and water resistance is good, and sealing effectiveness is good;
2, rational in infrastructure, supporting capacity is strong, and traffic safety is steady, reliable, and easy for installation, cost is low;
3, long service life;
4, adopt shallow pre-buried anchoring assembly, adapt to the requirement high-strength, slim, attractive in appearance of modern prestressed girder, applied widely, can be widely used in displacement 80mm and following freely-supported bridge or continuous bridge, alternative more board-changing type rubber stretching device.
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing:
Fig. 1 is the utility model embodiment 1 structural representation.
Fig. 2 is the utility model embodiment 2 structural representations.
Embodiment 1:
Fig. 1 has provided embodiment 1 structural representation.Referring to Fig. 1, pre-buried dowel 2 is arranged in the anchoring assembly 1, place the horizontal bar 3 of pre-buried dowel 2, be connected the fixedly dowel 4 on the pre-buried dowel.Shape of cross section for " F " but two shaped steel 5,6 of the born truck wheel weight of shape and relative displacement be separately fixed at fixedly on the dowel.On two shaped steel 5,6 annular seal space 7,8 is arranged respectively.The two ends of " V " shape rubber seal tape 9 are tightly packed in the annular seal space on two shaped steel.Two shaped steel 5,6 can be the split hot rolling, assembly welding is shaped.
Embodiment 2:
Fig. 2 has provided embodiment 2 structural representations.Present embodiment 2 is basic same with embodiment 1, and not existing together is anchoring assembly 10 structure differences, and pre-buried anchor bar 11 and horizontal anchor bar 12 placed on it are arranged in the anchoring assembly 10.
Claims (2)
1, the shallow-layer bridge expanssion joint, it is characterized in that having in the described shrinkage joint anchoring assembly, symmetry be loaded on the shape of cross section that contains annular seal space in the anchoring assembly for " F " but two shaped steel of the born truck wheel weight of shape and relative displacement, the two ends of rubber seal tape are tightly packed in respectively in the annular seal space on two shaped steel.
2, shallow-layer bridge expanssion joint as claimed in claim 1 is characterized in that the shape of cross section of described rubber seal tape is " V " shape.
