Abstract
The invention relates to a bridge dragging slideway device. The bridge dragging slideway device is characterized by comprising a steel plate protecting boot, a stainless steel plate and a tetrafluoride plate, an embedded steel plate chute, anchoring rebars and a bearing platform, wherein the groove of the bearing platform is internally and fixedly connected with the embedded steel plate chute; the anchoring rebars are arranged in the bearing platform at equal intervals and connected with the side wall of the embedded steel plate chute; the embedded steel plate chute is provided with the tetrafluoride plate; and the steel plate protecting boot is fixedly connected with the stainless steel plate. The device can ensure that bridge construction is carried out on the premise of non-interruption of city arterial street traffic and railway train operation and non migration of city pipe network infrastructure, and has obvious effect in the aspects of solution of city bridge reconstruction and mutual influence of city traffic and railway operation, a traditional frame bridge jacking method is innovated into a door type rigid frame dragging construction method, the influence of engineering on periphery traffic is properly solved, and significant economic results in society are achieved.
Description
Technical field
The invention belongs to the runner device field, relates to a kind of dilatory runner device of bridge that is applied in the bridge construction particularly.
Background technology
Along with demands of social development, the building of many mature cities can not satisfy the needs of modern society, like the railway bridge in the city; Because of build the age of a specified duration, the aperture is little, more and more can not satisfy demands of social development, and Along with people's growth in the living standard, vehicle is more and more; Traffic congestion also needs newly-built a lot of overpass bridges, however the building of the maintenance of railway bridge or enlarging construction and new bridge; Traditional method is a frame structure bridge jacking, need the traffic major trunk roads sealing in city and the interruption of railway operation be caused very big influence to traffic; And the underground various pipe networks in city gather, and also need migration, and the influence that people's life is caused is very big; Because these problems that exist cause very big pressure to bridge construction, thereby have fettered Traffic Development.
Summary of the invention
In order to overcome the above problems, the purpose of the invention provides and is a kind ofly guaranteeing the major urban arterial highway traffic and railways train operation does not interrupt, the bridge that can carry out bridge construction under the nonmigratory prerequisite of urban pipe network infrastructure is drawn runner device.
To achieve these goals, the technical scheme of the invention employing is: bridge is drawn runner device, it is characterized in that: protect boots, corrosion resistant plate, tetrafluoro plate, pre-embedded steel slab chute, anchor bar and cushion cap by steel plate and form; Be fixedly connected the pre-embedded steel slab chute in the groove of cushion cap, the equidistant anchor bar that is provided with in both sides of pre-embedded steel slab chute in the cushion cap, anchor bar is fixedly connected with the sidewall of pre-embedded steel slab chute, and the pre-embedded steel slab chute is provided with the tetrafluoro plate; Steel plate protects boots and is embedded in the member bottom on top during the concrete element precast, and steel plate protects boots and is fixedly connected with corrosion resistant plate.
The thickness of described corrosion resistant plate is 0.8～1.2mm, and the thickness of described tetrafluoro plate is 4.8～5.2mm.
Whenever be provided with anchor bar in the cushion cap at a distance from 0.5 meter.
The beneficial effect of the invention is:
1, the time of producing once lacks, easy construction, and features simple structure is easy to install;
2, take up room for a short time, do not need close traffic major trunk roads and railway operation to interrupt, thereby do not influence urban traffic, make the both sides road;
3, need not move Urban Buried Pipeline Network, drop to the influence of City Buried Pipeline minimum;
4, the mobile concrete member of assurance is walked in runner device, reduces potential safety hazard, reduces construction cost.
The invention can guarantee not interrupt in major urban arterial highway traffic and railways train operation, carry out bridge construction under the nonmigratory prerequisite of infrastructure under the bridge, and traditional frame structure bridge jacking innovation is the dilatory method construction of the firm structure of gate-type; Solve Urban Bridge reconstruction construction and urban traffic and railway operation influence each other aspect effect obvious; Urban road and railway transportation are not all interrupted in the work progress, and not only bridge body construction safety has also been properly settled the influence of engineering to peripheral traffic; Urban Buried Pipeline Network is without moving; Significantly reduced investment cost, advanced technology has the significant social economic benefit.
Description of drawings
Fig. 1 is the structural representation of the invention
The specific embodiment
As shown in Figure 1, bridge is drawn runner device: protect boots (1), corrosion resistant plate (2), tetrafluoro plate (3), pre-embedded steel slab chute (4), anchor bar (5) and cushion cap (6) by steel plate and form.
Be fixedly connected pre-embedded steel slab chute (4) in the groove of cushion cap (6); The equidistant anchor bar (5) (present embodiment is selected whenever to be provided with anchor bar (5) at a distance from 0.5 meter) that is provided with in the both sides of the interior pre-embedded steel slab chute of cushion cap (6) (4); Anchor bar (5) is fixedly connected with the sidewall of pre-embedded steel slab chute (4), and pre-embedded steel slab chute (4) is provided with tetrafluoro plate (3); Steel plate protects boots (1) and is fixedly connected with corrosion resistant plate (2).
The thickness of corrosion resistant plate (2) is 0.8～1.2mm, and the thickness of tetrafluoro plate (3) is 4.8～5.2mm.
During construction, earlier, needs make cushion cap on carrying out the position of bridge construction, when prefabricated, and with the both sides of the pre-embedded steel slab chute anchor bar of burn-oning, half meter one, fix with cushion cap then, guarantee that the pre-embedded steel slab chute is unlikely to mobile when the concrete member is dilatory on top; Steel plate protects boots and is embedded in the member bottom when concrete member (7) is prefabricated on top, fixes with anchor bar too, guarantees that it does not move.Like this, at first the concrete member of bridge does not influence the local earlier prefabricated of traffic at other, passes through the pre-embedded steel slab chute on the cushion cap then, and the slip between corrosion resistant plate and tetrafluoro plate is dragged to assigned address with top concrete member and fixes.
Claims (3)
1. the dilatory runner device of bridge is characterized in that: protect boots (1), corrosion resistant plate (2), tetrafluoro plate (3), pre-embedded steel slab chute (4), anchor bar (5) and cushion cap (6) by steel plate and form; Be fixedly connected pre-embedded steel slab chute (4) in the groove of cushion cap (6); The equidistant anchor bar (5) that is provided with in the both sides of the interior pre-embedded steel slab chute of cushion cap (6) (4); Anchor bar (5) is fixedly connected with the sidewall of pre-embedded steel slab chute (4), and pre-embedded steel slab chute (4) is provided with tetrafluoro plate (3); Steel plate protects boots (1) and is embedded in the member bottom when concrete member (7) is prefabricated on top, and steel plate protects boots (1) and is fixedly connected with corrosion resistant plate (2).
