Flexible and denoising comb teeth retractor device
Technical field
The present invention relates to the construction of road and bridge technical field, relate in particular to a kind of comb teeth retractor device that is applied in the bridge construction.
Background technology
In order to eliminate or to reduce thermal stresses in the bridge construction, or the subsidiary stress that breathing brings occurs, particularly generally all be provided with stretching device in the deck system in bridge construction owing to other reasons causes structural meterials.
The stretching device that is usually used in highway bridge mainly contains forms such as rubber type stretching device, deformed steel formula stretching device, the board-like stretching device of broach.Wherein the board-like stretching device of broach is the most common pattern that is used for big stroke, and because of its other forms of relatively stretching device is sayed, travelling, persistence are better, so still be widely adopted now.
The general main metal sheet by two opposed rake tooths or broach structure of the board-like stretching device of common broach constitutes.The material of metal sheet can be with steel or aluminium alloys, the end of two metal sheets can be respectively with prestressed anchor fasten, common anchor is fastened or syndeton such as bolt links to each other with the beam body.The external surface of the board-like stretching device of common broach is a steel plate, and fineness is higher, and surface elasticity hardness, color and pitch differ bigger, easily jumps car when vehicle is crossed seam, and noise is bigger.
In actual use, the shortcoming of the board-like stretching device of existing broach is also more obvious:
1. after the tooth plate of metal material was installed on the concrete, because concrete precision is difficult to improve, the board-like stretching device integral level of broach error was bigger after installing, and ride comfort is very poor.
Two next doors of the board-like stretching device of 2. existing broach generally need be provided with concrete white band, and it is big therefore to excavate width.Steel plate, concrete, three kinds of surface material soft or hards of pitch different in kind, irregularity when wheel is advanced easily produces noise.And colour contrast is bigger, and visual effect is not good yet.
3. the waterstop rubber tile is floated between the corrosion resistant plate of tooth plate and Liang Tishang.Because the waterstop rubber tile has elasticity, passing through the die-cut of constantly vertical pressurized and vehicle ', the tooth plate that is positioned at waterstop rubber tile upper strata forms the distortion in multilayer component gap easily, cause the tooth plate bolt looseness, bad phenomenon such as final generation is leaked, bolt and nut damage, easily jump car, noise is big; Also easily leak outward appearance that destroys a bridge and durability.
Be to reduce the influence to environment, improve the outward appearance and the durability of bridge, those skilled in the art is devoted to develop a kind of novel comb teeth retractor device with noise reduction, waterproof, function such as anti-jump.
Summary of the invention
Because the above-mentioned defective of prior art, technical problem to be solved by this invention provides a kind of comb teeth retractor device with noise reduction, waterproof, function such as anti-jump.
For achieving the above object, the invention provides a kind of flexible and denoising comb teeth retractor device, be used to be connected the first beam body, the second beam body of concrete material, described flexible and denoising comb teeth retractor device comprises at least: the first metal tooth plate that manufactures and the second metal tooth plate; One flexible water stop, described flexible water stop have first wing and second wing; Also comprise one first special-shaped side bar member, the described first special-shaped side bar member is arranged between described first metal tooth plate and the described first beam body; The described first special-shaped side bar member comprises the first member body, is fixed with a plurality of connection straps and leg frame on the not ipsilateral of the described first member body respectively; Also offer first caulking groove on the described first member body with the form fit of described first wing; And one second special-shaped side bar member, the described second special-shaped side bar member is arranged between described second metal tooth plate and the described second beam body; The described second special-shaped side bar member comprises the second member body, is fixed with a plurality of connection straps and leg frame on the not ipsilateral of the described second member body respectively; Also offer second caulking groove on the described second member body with the form fit of described second wing; Described first wing of described flexible water stop is embedded in described first caulking groove, and described second wing of described flexible water stop is embedded in described second caulking groove.
In the prior art, general all kinds of stretching devices all are subjected to aspect limitation such as product design and manufacture craft, and product is installed the back global error all between 1mm~2mm.Among the present invention, the metal tooth plate is installed in the Liang Tishang of concrete material by means of the special-shaped side bar member of metal material, aspect structure design, be provided with some roads and be used as the fixedly connection strap of batten of horizontal direction, and adopt moulds of industrial equipment to install, device of the present invention is controlled between 0.4~0.5mm in integral level error after the installation, and the installation horizontal error is little.Because the accuracy of form and position of the special-shaped side bar member self of metal material guarantees easily, therefore the present invention has just overcome in the prior art when metal tooth plate is directly installed on the Liang Tishang of concrete material, the global error of the stretching device that causes owing to the accuracy of form and position that is difficult to guarantee concrete self.
Among the present invention, the transmission of load bearing capacity mainly is that the metal tooth plate has good parallel transmission and resilience by the interdigitated electrode structure metal tooth plate above being positioned at, and the driving stationarity is good, flexible evenly, advantage such as deviation is little has greatly improved anti-jump, the anti-acoustic capability of product.
When stroke is big, except that the board-like stretching device of broach, also can select deformed steel formula stretching device for use, but the latter must be provided with many longerons, can produce resonance and beat.And because two side bearing case height limitation, the flexible preformed groove hole degree of depth is too dark, can not adapt to precast beam and install.
Stretching device of the present invention structurally surmounted existing deformed steel formula stretching device, eliminated resonance substantially and beated.In addition, the setting height(from bottom) of stretching device of the present invention enough is suitable for the precast beam installation.
In better embodiment of the present invention, the both ends of described first member body or the described second member body are formed with the portion that bends up upwards respectively.
Because the caulking groove embedding mutually in flexible water stop and the special-shaped side bar member, sealing performance is better than existing toothed plate type stretching device.Simultaneously, the two ends of the special-shaped side bar member among the present invention are lifted up on also and are formed one and bend up portion, have greatly improved the water resistance of product, have prolonged the application life of product.
And flexible water stop is secretly put below the metal tooth plate, has both significantly reduced maintenance cleaning work amount from now on, is not subjected to the extraneous puncture in road surface to wait destruction again, makes its longer service life.
In another better embodiment of the present invention, the surface of described first metal tooth plate and/or the described second metal tooth plate is coated with a rubber layer, forms glue face metal sheet.
Because the surface detail of glue face metal tooth plate is strong for the doughnut earth-grasping force, especially surface elasticity hardness is consistent substantially with the pitch elastic hardness, make vehicle by the time driver feel extremely comfortable, the color basically identical of tooth plate surface color and flexible pavement, make the driver not have sense of fatigue, comfortable just as travelling on whole flexible pavement by time between seam, the driving stationarity is good, and noise is low.
And product damage in a single day, it is quite convenient to change.After watering ointment in the flexible slit of teeth groove, overall appearance, the lines flow smoothly.
Compare existing interdigitated electrode structure stretching device, flexible and denoising stretching device of the present invention has also dwindled installs the excavation width, delete two limit concrete white bands, adopted the filling of polyurethane-modified elastic body (EMR) material to condense between two limits of stretching device and the flexible pavement.Product is consistent with road surface black, and smooth lines produce U.S. of a kind of one integrated mass.
