Abstract
The utility model provides a bridge telescopic device, comprising anchor bolts. The utility model is characterized in that the utility model is provided with an upper fixed steel plate, a lower fixed steal plate and a strip-shaped rubber body; two edges of the cross section of the rubber body are provided with holding parts which are provided with holding heads; the middle part of the rubber body is provided with a hollow section; The contact face of the upper steal plate and the lower steel plate is provided with a holding structure which is accordant with the holding part of the rubber body. The utility model has the advantages of reasonable structure, simple property, easy fabrication, good quality, low cost, long service life, convenient maintenance, etc., and is particularly suitable for the treatment of the telescopic gap of the middle and the small highway bridge.
Description
The utility model relates to bridge dilatation joint treating apparatus technical field.
Stretching device is a kind of member that uses in the bridge construction, and the reasonability of its structure design directly affects the application life of traffic safety and bridge.The board-like stretching device of a kind of rubber is arranged, and it is to cover on the shrinkage joint with the thinner stretchable rubber bodies in a kind of centre, and two ends are given in the beam-ends steel plate with bolt and being stayed in the groove; Its shortcoming is the impact that rubber bodies is directly born wheel, and driving is uneven, easily vibrations, and rubber bodies easily wears out, destroys, and application life is short.Have kind of a hair to rein in seam, it be with special-purpose shaped steel as primary structure member, play waterproof action with " V " type sheet rubber; Its shortcoming is, costs an arm and a leg, and be difficult to promote, and shaped steel processing needs special large-scale special equipment.Also have kind of a special-shaped rubber steel plate shrinkage joint, it is that " W " type rubber strip two ends are screwed in the welding slotted-angle shelving; Its weak point, the one, the rubber strip unreasonable structure, easily aging, frangibility, poor durability, the 2nd, the time one is long, and screw gets rusty, and can not dismantle, and angle steel is yielding, and the inconvenience maintenance is so its application also is restricted.
The purpose of this utility model provides a kind of novel bridge extension joint, and it is reasonable in design, processing is simple, cost is low, the rubber strip structure is not fragile, the life-span is long, and installation and maintenance are convenient, thus can be on highway bridge wide popularization and application.
The utility model is achieved in that a kind of bridge extension joint, comprise anchor bolt, it is characterized in that having the retained part of the cross section both sides of the last fixation steel plate in strap bolt hole, following fixation steel plate and strip rubber bodies, rubber bodies for the band clamping head, the centre is a hollow section, and the contact surface of last fixation steel plate and following fixation steel plate is provided with the clamp structure that adapts with the rubber bodies retained part.
Above-mentioned hollow section is preferably garden annular or ellipse garden annular.Be preferably in hollow section or garden ring form ring section, ellipse garden above a boss and bridge floor are arranged substantially on a horizontal plane so that the gap is littler above in the use, be difficult for embedding stone, influence the application life of rubber bodies.The chuck of the both sides retained part of rubber bodies cross section can be the shape of garden shape, ellipse garden shape, half garden shape, square or other curves, rectilinear(-al), with garden shape, ellipse garden shape for well, so that clamping and not fragile, preferably take angle, garden transition structure in the rubber bodies structure, concentrated, fragile to prevent stress.
Also can strengthen its stability in using with descending the reinforcement metal support weldering in fixation steel plate and bridge or the bridge chair concrete to be one.
On last fixation steel plate, preferably be provided with nut mounting or dismounting groove, wherein, can be filled with fillers such as drop sand or polyammonium grease glue.
Since the special construction of the utility model rubber bodies, make it not fragile, long service life; Go up the loading and unloading of compressed steel crab bolt owing to adopt, so easily change; Employing presses down steel plate, makes its fastness better.This reasonable in design, simple, easily processing, installation and maintenance are convenient, and cost is low, inexpensive, long service life, traffic safety, steady is avoided the corrosion of rainwater dirt, and it is convenient to remove dirt, is particularly suitable for wide popularization and application on middle or small highway bridge.
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing, but not as to qualification of the present utility model.
Fig. 1 is the board-like stretching device user mode of a rubber schematic diagram in the prior art.
Fig. 2 is that hair is reined in the crack structure schematic diagram in the prior art.
Fig. 3 is a special-shaped rubber strip steel plate expanded joint structure schematic diagram in the prior art.
Fig. 4 is example structure schematic diagram of the utility model.
Among Fig. 1-Fig. 3,1 is rubber bodies, and 2 is anchor bolt, and 3 is deformed steel, and 4 is angle steel.
Among Fig. 4,1 is rubber bodies, and 2 is anchor bolt (double), and 5 is last fixation steel plate, and 6 are following fixation steel plate, and 7 is the reinforced support in the concrete, is filled with sand asphalt in the groove above the last fixation steel plate, and 8 is beam, and 9 is the platform back of the body.
Claims (5)
1, a kind of bridge extension joint, comprise anchor bolt, it is characterized in that: the last fixation steel plate in 2 strap bolt holes and the following fixation steel plate in 2 strap bolt holes clamp the both sides of a strip rubber bodies and be fixed on the basis on bridge expanssion joint both sides respectively, in the middle of the cross section of strip rubber bodies is hollow section, clamping head is established on both sides, and the contact surface of last fixation steel plate and following fixation steel plate is provided with the clamp structure that adapts with the rubber bodies clamping head.
2, bridge extension joint according to claim 1 is characterized in that described hollow section is garden annular or ellipse garden annular.
3, bridge extension joint according to claim 2 is characterized in that a boss and bridge floor being arranged on a horizontal plane above the annular hollow section of ellipse garden annular or garden.
4, according to claim 1,2 or 3 described bridge extension joints, the chuck that it is characterized in that rubber bodies cross section both sides is the shape of garden shape, ellipse garden shape, square or other curves, rectilinear(-al).
