The present invention relates to a kind of bridge expansion joint installation, it is the link technique field belonging to a kind of bridge expanssion joint in particular.
Background technology
Bridge extension joint be for make vehicle smoothly pass bridge floor and meet bridge floor distortion needs, the various devices set by bridge floor expansion joint.Stretching device should be able to meet following requirements: in the both direction of parallel vertical in bridge axes, beam body is energy free-extension all, except itself having enough intensity, firmly should link with deck paving part, and there is durability, vehicle by time should smooth-going, without jumping car and noise is little, make ride comfort; Have good dense water and drainage and easy construction, and keep in repair easy, reasonable price, be more convenient for checking, maintenance and removing groove dirt.
Stretching device is link the weakest in bridge construction, because stretching device directly bears the percussion of wheel cyclic reverse loading, there is very small out-of-flatness this place that will make under carload effect to be severely affected effect, the most easily destroyed and the replacing that needs repairing.Conventional stretching device is broadly divided into five large class, that is: steel supporting type, rubber slat, modulus supporting type and seamless expansion-contraction devices by mode of transfer force and construction features.First three kind can be implemented in factory's processing and manufacturing in advance, be convenient to mass production, but the cost of steel supporting type, modulus support type expansion installation is higher, and rubber slat stretching device is easily aging, and the overall possibility destroyed is comparatively large, and maintenance cost is higher.And these three kinds of expansion gap devices are opening shrinkage joint, easily intake, barrier properties is poor, can not play a very good protection to bridge panel, bearing and understructure.
Gapless stretching device structure does not expose to bridge floor, in the flexible gap of beam end, insert elastomeric material and spread waterproofing materials, then making VISCOELASTIC FIBER COMPOSITES in bridge deck pavement, the deck paving at expansion joint place and other parts of mating formation is made to form non-individual body, bear flexible with the distortion of the materials such as the asphalt concrete of continuous seam, it can adapt to dilatation and a small amount of rotational deformation of bridge superstructure, and the main feature of expansion joints without seals has: (1) is applicable to the thin tail sheep bridge expanssion joint of horizontal movement within 50mm; (2) this kind of shrinkage joint has good intensity, elasticity, has high resiliency, can resist the impact of wheel, have higher road-ability under wheel quick washing power; (3) sealing is better, and better corrosion-resistant, property is longer for application life; (4) bridge floor is smooth seamless, is convenient to bridge floor cleaning and safeguards; (5) easy construction, need not embedded bar.Throughout the year, after installing shrinkage joint, get final product open to traffic, the maintenance transformation of small bridge on the arterial highway being suitable for heavy traffic flow; (6) cost is lower, better economic benefit, and therefore, its ratio shared in bridge extension joint is also increasing.
The working procedure at gapless shrinkage joint is included in the middle of shrinkage joint and tamps with sponge, steel plate is layered on bridge again and sews on and fixing seal steel plate, on-the-spotly also need heating raw materials such as pitch, clean building stones, stir, pave, and imposes pressing again, paper etc. is taped in oven dry, both sides after its cooling certain hour.Due to the restriction of constructor's technical level, sense of responsibility and construction site condition, its construction quality is difficult to be protected, and work progress is long, environmental pollution comparatively large (flue dust of heated asphalt), and energy consumption is large, the larger waste of existence.In addition, at present conventional expansion joints without seals also exist stroke little (stroke is no more than 50mm), easily occur cold cracking, high temperature pass and with the defect such as the bonding deficiency in original road surface, reduce its application life.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of and do not need to carry out in-site installation steel plate, heating, stirring pitch and sandstone, pave, flatten, the bridge gapless shrinkage joint of the technique such as cooling fills prefabricated component, realizes the environmental protection of bridge expansion joints without seals, quick, the standardization of low energy consumption, high-quality construction.
The concrete technical scheme that the present invention solves the problem is: the Interal fixation carried out original at the construction field (site), asphalt heating, stir, pave, flatten, the manufacturing process such as cooling factory realize scale, mass, centralization production to make expansion joints without seals device, at the construction field (site) only need bridge expansion joints without seals prefabricated component is bonded to bridge seam through smooth bottom land and the part of two ends being stretched out prefabricated component fix with bridge both sides.
Compared with prior art, the invention has the advantages that: a large amount of operations of building-site are concentrated on factory and carry out by it, and in prefabricated component, add fibrous material, elastic network(s), the devices such as steel plate, simplify the difficulty of site construction operation and construction, improve product quality, construction quality and efficiency, reduce the labour intensity of site operation personnel, waste of raw materials and the pollution to environment, save the time of shrinkage joint installation, decrease because constructing the traffic impact brought at shrinkage joint, can accelerating construction progress and improve the stroke at shrinkage joint greatly.
