Description
Technical Field
The utility model relates to an expansion joint template technical field, in particular to expansion joint template structure for concrete road surface.
Background
The expansion joint is a structural joint provided at an appropriate position along the direction of a construction joint of a building or a structure to prevent the structure from being cracked or damaged due to a change in weather temperature (thermal expansion or cold contraction). The expansion joint divides building components above a foundation such as a wall, a floor and a roof (except a wooden roof) into two independent parts, so that the building or the structure can horizontally expand and contract along the length direction.
The highway bridge expansion joint is a specially reserved structure when a highway bridge is built, and is mainly used for preventing factors such as temperature change and the like from influencing the safety of the highway bridge. The expansion joint is required to be freely telescopic in two directions parallel to and perpendicular to the axis of the bridge, and the expansion joint is firm and reliable, and when a vehicle runs, the vehicle is smooth and free of sudden jump and noise; the rainwater and garbage soil can be prevented from infiltration and blocking; the installation, the inspection, the maintenance and the dirt elimination are all simple and convenient. With the development of highway service and the rapid increase of traffic flow in China, the expansion joints built in early stage are continuously damaged and need to be maintained and replaced.
At present, rubber cushion blocks are adopted to fix expansion joints in expressways built in China, and impact of steel rails on vehicles is reduced. The vehicle load can be borne under the condition of large displacement. Years of maintenance practice proves that the expansion joint becomes one of the most frequently damaged parts of the bridge structure. The expression form of the method is diseases such as breakage, beam breakage, connector damage and the like, and the method is increased year by year in geometric multiples in recent years. The method has great influence on the driving safety and the driving speed, and also can cause great damage to the automobile, so that the service life of the bridge of the highway is greatly shortened.
CN 108149566A, a highway bridge expansion joint, including a front supporting steel plate, a rear supporting steel plate, two L-shaped angle steels, L-shaped angle steels horizontal placement, the front supporting steel plate and the rear supporting steel plate respectively placed on the L-shaped angle steels, rubber waterstops installed between the two L-shaped angle steels and the front supporting steel plate and between the two L-shaped angle steels and the rear supporting steel plate, a reserved hole opened on the rubber waterstop, a supporting gasket arranged in the reserved hole, the L-shaped angle steels and the rubber waterstops fixed with the front supporting steel plate and the rear supporting steel plate through screws, the end of the front supporting steel plate higher than the end of the rear supporting steel plate, and a height difference △ H formed between the front supporting steel plate and the rear.
In the invention, due to the height difference △ H, when a vehicle passes through the expansion joint at normal speed, the tire drop point is positioned on the horizontal plane of the rear support steel plate, so that the bridge main body is subjected to positive pressure in the vertical direction, and the impact force of the vehicle tire on the expansion joint is avoided, therefore, the service lives of the expansion joint and the bridge main body are greatly prolonged, but the anchoring strength of the expansion joint and the highway pavement of the invention is low, and the expansion joint is easy to fall off after long-time use, thereby influencing the use of the highway.
Disclosure of Invention
Not enough to prior art exists, the utility model aims to solve the technical problem that, it is high to provide an anchor intensity, long service life, and drainage efficiency is high, and the shock attenuation is effectual, the not deformable's an expansion joint template structure for concrete road surface simultaneously at the telescopic.
The utility model discloses a realize that the technical scheme that above-mentioned purpose adopted is: an expansion joint template structure for a concrete pavement comprises two templates which are arranged in an expansion joint of the concrete pavement and are arranged in parallel relatively, a plurality of telescopic supporting mechanisms with telescopic length which are uniformly arranged between the two templates, a plurality of conical anchoring steel pipes which are arranged outside the templates and are used for enhancing the anchoring strength with concrete, and a damping mechanism which is arranged at the upper end of the template and has a damping effect on the concrete pavement, wherein the templates comprise vertical templates which are attached to the inner wall of the expansion joint and transverse templates which are parallel and level with the concrete pavement, the telescopic supporting mechanism comprises a telescopic sleeve which is vertically fixed with a vertical template at one side, a telescopic sleeve rod which is arranged inside the telescopic sleeve and is matched with the telescopic sleeve in shape and size is fixed inside the telescopic sleeve, one end of the telescopic sleeve rod is fixedly connected with the telescopic spring, and the other end of the telescopic sleeve rod is vertically and fixedly connected with the vertical, the surface of anchor steel pipe evenly is equipped with a plurality of circular through-holes, damper include with the damping sleeve of horizontal template vertical fixation, locate inside and damping sleeve shape size assorted damping loop bar of damping sleeve, locate damping loop bar upper end and be used for covering the expansion joint and play the arc shock attenuation piece of cushioning effect, the damping sleeve is inside to be fixed with damping spring, the one end and the damping spring fixed connection of damping loop bar, the other end and arc shock attenuation piece sliding connection.
Furthermore, the arc-shaped shock absorption sheet is provided with a sliding groove matched with the shock absorption loop bar in size and shape.
The utility model discloses an expansion joint template structure for concrete road surface's beneficial effect is:
through the mutual matching of the telescopic sleeve, the telescopic spring and the telescopic sleeve rod in the telescopic supporting mechanism, the pavement can be prevented from being cracked or damaged due to weather and climate change. The round through holes arranged on the anchoring steel pipes can enable concrete to permeate into the anchoring steel pipes, so that the combination of the template and the concrete pavement is firmer, the template is not easy to fall off after long-time use, and the service life of the template is prolonged. The shock attenuation piece among the damper can be used to cover the expansion joint, through with the shock attenuation sleeve, shock attenuation loop bar and damping spring's mutually supporting can produce the cushioning effect to the vehicle through the expansion joint, reduces the vehicle and jolts, plays the guard action to the expansion joint template simultaneously, and the groove that constructs that forms between two vertical templates can play the drainage effect to the road surface. When the concrete expands or contracts, the two vertical templates are close to or far away from the middle, and the sliding grooves in the arc shock absorption pieces can ensure that the positions of the arc shock absorption pieces are unchanged, so that the templates can freely move. The utility model discloses an expansion joint template structure anchor intensity is high, long service life, and drainage efficiency is high, and the shock attenuation is effectual, non-deformable simultaneously at the telescopic.
