Abstract
The utility model relates to a fast-assembled bridge expansion device and belongs to the field of bridge engineering facilities. The fast-assembled bridge expansion device comprises bases, a fixed plate, a moving plate and a water stop. The bases are fixedly connected with embedded plates of two beams which are adjacent along a bridge gap in anchored manner. One end of the moving plate, which is a moving end, is horizontally placed on the surface of the base below the other beam. A low-friction stainless steel plate is fixedly connected to the surface of the base below the beam at the moving end. The moving plate slides with respect to the low-friction stainless steel plate on the base below the corresponding beams so as to adapt a gap between the two adjacent beams. The fast-assembled bridge expansion device with the clear function is simple in structure. The fast-assembled bridge expansion device is fixed by steel structure welding and thus is simple to construct, fast and convenient. The trouble of concrete construction and the concrete curing period after the concrete construction are omitted. Labor, time and materials are economized. The fast-assembled bridge expansion device has the outstanding feature of install-and-use.
Description
Technical field
A kind of quick mounting type bridge extension joint of the utility model belongs to bridge engineering facility field.
Background technology
Need to install stretching device on the bridge to adapt to the bridge telescopic variation.Current Flex Equipment Installation generally all adopts the mounting means of pre-buried dowel, need to dig darker notch and find out embedded ribs, has welded concrete placing after the crab-bolt, and theoretical minimum will wait more than 15 days concrete strength to reach rear just to be open to traffic.But the time of leaving the stretching device installation in the bridge construction for is not very long, and this has just caused concrete strength not reach requirement just has vehicle to travel in the above, has had a strong impact on behavior in service and the life-span of stretching device.General this stretching device owing to the concrete strength reason, just begins about 1 year destroyed phenomenon progressively to occur after bridge comes into operation, and needs repairing or changes.
The utility model content
The purpose of this utility model provides a kind of quick mounting type bridge extension joint, with the installation effectiveness of raising bridge extension joint, and exempts stretching device rear placing of concrete engineering and necessary maintenance duration thereof are installed.
The utility model is comprised of base, fixed head, portable plate and waterstop, base is the embedded board anchor connection of the two slice beam bodies adjacent to the gap with suitable bridge respectively, one end of portable plate is fixedly connected with the base of a slice beam body, it is movable end that portable plate other end level is seated in another sheet beam body susceptor surface, this activity end carriage body susceptor surface is fixedly connected with low friction corrosion resistant plate, by the relatively slip of the low friction corrosion resistant plate of its corresponding beam body base of portable plate, with the variation in the gap that adapts to two adjacent beams bodies.
The movable end base length of above-mentioned portable plate is at least 2.5-3 times of adjacent two beam body spaces.
The low friction corrosion resistant plate of the anchoring susceptor surface of above-mentioned portable plate and movable end carriage body susceptor surface is in same level.
Above-mentioned waterstop is arranged on the gap location of two adjacent beam bodies of gap, be pressed in corresponding beam body anchoring base below.
The utility model is simple in structure, and definite functions is utilized during welding for steel structure mode fastening devices, construction is simple, and is efficient and convenient, greatly omitted the loaded down with trivial details of concrete construction and concrete curing duration thereafter, the saving of labor, save time, the material saving, have the outstanding feature of plug and play.
Description of drawings
Fig. 1 the utility model structural representation
The specific embodiment
How now further specify by reference to the accompanying drawings the utility model implements:
How existing accompanying drawings is installing the utility model stretching device along bridge two beam bodies of A, B and the beam-ends clearance C adjacent to the gap: shown in Fig. 1, be provided with embedded board 6 among the beam body A, be provided with embedded board 8 in beam body B.Implementation step is as follows:
1, according to drawing requirement, when the beam body is built, embedded board-6 and embedded board-8 are built with the beam body.
2, treat that the beam body is built and finish that after concrete strength satisfied, the foreign material on cleaning embedded board 6 and the embedded board 8 were with the upper plane of cement mortar leveling layer levelling embedded board 6 and embedded board 8.
3, base 1 and base 4 are placed on the seam both sides, determine the position according to drawing, and in pre-drilled welding hole full weld, base 1 and embedded board 6, base 4 and embedded board 8 are welded together, note controlling temperature during welding, in order to avoid burn out intermediate rubber layer.
4, weld after base 1 and the base 4, load onto waterstop 7.
5, the foreign material on cleaning base 1 and the base 4 according to drawing, are contained in portable plate 3 on the base 1, to position, good hole, and fix with bolt 2, and the other end lies in a horizontal plane on the base 4.
6, the foreign material of cleaning on the base 4 are contained in fixed head 5 on the base 4 by drawing, to position, good hole, with 3 pairs of good teeth of portable plate position, and fix with bolt 2.
7, treat after all installations infusion epoxy resin in bolt hole.After doing, epoxy resin can be open to traffic.
