The utility model provides a take bridge expansion joint of early warning structure has not only played the effect of protection bridge floor, can realize seismic warning in addition, reduces the bridge and is out of shape, does and realizes the urgent early warning of earthquake.
Description
Technical field
This utility model relates to bridge expanssion joint field, particularly relates to a kind of bridge expanssion joint with early warning structure.
Background technology
Along with China's science and technology is constantly progressive, the fast development of social production force level, the technology of science of bridge building is increasingly paid attention to by people, in the use procedure of bridge, the girder construction of bridge is due to the impact of the factors such as variations in temperature, concrete creep, automobile dynamic load, as easy as rolling off a log shrink or elongate phenomenon, thus causing that bridge beam end is subjected to displacement.Generation in order to avoid this phenomenon, generally require and bridge extension joint is set at movable end or the bridge floor breaking joint place of bridge superstructure, to realize displacement and the displacement at this position, ensure the traffic safety of highway bridge, in addition once run into earthquake or disaster, bridge expanssion joint can sense the very first time, it is possible to arrange prior-warning device whereby and earthquake is carried out early warning.
Utility model content
nullIn order to solve above-mentioned Problems existing，This utility model provides a kind of bridge expanssion joint with early warning structure，Not only act as protection bridge floor effect，And earthquake pre-warning can be realized，Reduce bridge deformation，Also the urgent early warning of earthquake can be realized，For reaching this purpose，This utility model provides a kind of bridge expanssion joint with early warning structure，Including runway block part、Early warning mechanism、Lean concrete bed course、Bitumen layer、Mutual edge angle steel、U-shaped steel plate and rubber filler rod，Described runway block part there is lean concrete bed course，Described lean concrete bed course there is bitumen layer，The lower end of two mutual edge angle steel is attached to the end face of corresponding row track block part，The bending end of mutual edge angle steel is inserted in corresponding lean concrete bed course，One runway Kuai Jianneiyou early warning mechanism，Described early warning mechanism is connected with the lower end of corresponding mutual edge angle steel，The top of two mutual edge angle steel is respectively arranged with a U-shaped steel plate，Two U-shaped steel plate openings are corresponding，The upper end of one U-shaped steel plate is inserted in the opening of another U-shaped steel plate，Rubber filler rod is had in two U-shaped steel plates.
Further improvement of the utility model, has fireprotection layer between described runway block part and lean concrete bed course, in order to prevent fire from can arrange fireprotection layer.
A kind of bridge expanssion joint with early warning structure of this utility model, bridge expanssion joint bottom runway block part is filled, and is installing earthquake prewarning device close to expansion joint position place, and electric wire pulls out from expansion joint, fireprotection layer is laid on above runway block part, re-lays lean concrete bed course afterwards.Now, continuous slab-deck is effectively checked, it is ensured that between each beam, gap has been cleaned and flexible width reaches after design needs, whether retractor device to be met construction and checks.Expansion joint main body is made up of 2 blocks of U-shaped steel plates, the staggered overlap joint of U-shaped steel plate, makes expansion joint comprcssive strength substantially increase, simultaneously, with there is the neoprene of 4 circular holes as packing material in the middle of U-shaped steel plate, not only springiness but also be prone to sticker, deformation requirements can be met and have both water-proof function.In the installation process at expansion joint, first should be undertaken lifting and in place by retractor device, and combination is actually needed the length determining channel-section steel, channel-section steel is vertically disposed at bridge floor by the form taking double; two limb after retractor device, T-bolt is finally utilized to sling retractor device, and on channel-section steel, it is fixed, after fixing, just should weld timely.Expansion joint function, from the shockproof angle of fire-proof and water-proof, is improved, is substantially increased the firmness degree at expansion joint, and improve the comfortableness of driving, alleviate the maintenance work of bridge and improve the service life of bridge by this bridge expanssion joint.
