Description
Technical Field
The utility model relates to a bridge connection structure specifically is a structure of radical cure bridge expansion joint percolating water.
Background
The problem that water leakage of the bridge expansion joint is always a technical problem in the construction and use process of the bridge is solved, and the phenomenon is particularly prominent in the use process of urban viaducts. In the past, when the expansion joint of the comb plate is installed, the main reason of 'water leakage in rainy days and water dripping in rain stops' under the bridge is caused by poor installation process and method of the waterproof rubber strip under the plate. Among the prior art, the technical scheme to the processing of bridge expansion joint junction antiseep mainly has a disclosed expansion joint department beam-ends percolating water eduction gear of CN 208105041U, its characterized in that: including fixing the left diversion board at left side bottom of a beam surface and fixing the right diversion board at right bottom of a beam surface, left side diversion board and right diversion board stretch out the partial cross section under the expansion joint and are the V-arrangement, and the V-arrangement opening is relative with the expansion joint drill way up, and the top in right V groove is arranged in to left side V groove, set up a plurality of parallel arrangement's of each other riser on the lower surface of left side V groove left surface, the riser is followed the bottom broken line that extends left V groove from left V groove left surface top, sets up the T word roof beam that diaphragm and riser constitution cross section be T shape on the riser, the bent plate is established to the left side board end in right V groove, evenly sets up a plurality of T shape shrinkage pools that use with the cooperation of T word roof beam on the bent plate, makes the bent plate slide at left V tank bottom, and left side V groove and right V groove incline to a direction. The beam end leakage water leading-out device at the expansion joint can lead out all the leaked water to the sewer pipe after the expansion joint is deformed; the left V-shaped groove on the upper layer and the right V-shaped groove on the lower layer ensure that the leaked water is completely led out to the sewer pipe.
However, in practice, the waterproof adhesive tape under the telescopic seam plate is fixed at the plane position of the upper part of the angle steel at intervals by adopting the dovetail fibers, a waterproof flow guide layer and a bridge floor used in the technology are in plane lap joint, a relatively horizontal gap is still left between the waterproof flow guide layer and the bridge floor, the waterproof adhesive tape cannot be completely sealed and fixed after the method is installed, water flows out along the gap under the condition of untimely drainage after the method is fixed, and the hidden danger of water leakage is easily caused by water seepage at the interval part. Does not have strict anti-seepage effect.
Disclosure of Invention
The utility model discloses a solve the technical problem that the bridge junction leaked, provided a structure of radical cure bridge expansion joint percolating water.
The technical scheme of the utility model, a structure of radical cure bridge expansion joint percolating water, including left side roof beam, right side roof beam, be equipped with the fishback expansion joint at the seam crossing upside of left side roof beam, right side roof beam, pre-buried angle steel that is equipped with respectively in left side roof beam and right side roof beam, angle steel and pre-buried reinforcing bar welded fastening, angle steel set up perpendicularly on one side, be equipped with waterproof rubber strip between the angle steel, waterproof rubber strip both ends be the couple, the couple hang on the perpendicular edge of angle steel, be equipped with the stainless steel buckle in the couple outside.
Compared with the prior art, the utility model discloses waterproof stripe's both sides have improved under the board of will rising the contraction joint to at the internal angle steel of having installed of roof beam, closely fixed together through waterproof stripe and angle steel, not only can lead the bridge drainage system with ponding in the expansion joint through waterproof stripe, prevented the infiltration in adhesive tape both ends gap moreover, effectively stopped the emergence of the seepage water condition under the bridge. Especially, the effect is more obvious for the urban bridge with the traffic requirement under the municipal viaduct.
Drawings
FIG. 1 is a schematic structural diagram of the present invention
FIG. 2 is a schematic view of a conventional apparatus
In the figure: 1-left side beam, 2-embedded steel bar, 3-angle steel, 4-stainless steel buckle, 5-waterproof rubber strip, 6-fishback expansion joint and 7-right side beam.
Detailed Description
As can be seen from fig. 2, a structure of radical cure bridge expansion joint percolating water, including left side roof beam 1, right side roof beam 7, be equipped with fishback expansion joint 6 at the seam crossing upside of left side roof beam 1, right side roof beam 7, buried angle steel 3 in left side roof beam 1 and right side roof beam 7 in advance respectively, angle steel 3 and embedded steel bar 2 welded fastening, angle steel 3 set up perpendicularly on one side, be equipped with waterproof rubber strip 5 between angle steel 3, 5 both ends of waterproof rubber strip be the couple, the couple hang on the perpendicular edge of angle steel, be equipped with stainless steel buckle 4 in the couple outside.
The length of the hook is not less than 2.5 cm. The stainless steel buckles 4 are arranged at a distance of 60cm along the longitudinal direction.
On the construction site, the specific operation method is as follows:
1. determining the size of a waterproofing strip
Determining the distance between the positioning angle steels according to the lifting shrinkage joint model of the comb plate designed by the bridge and the site construction condition, and then determining the width of the waterproof adhesive tape according to the distance between the positioning angle steels; and determining the length of the waterproof adhesive tape according to the width of the bridge and the length of the expansion joint.
2. Processing rubber strips according to determined dimensions
The waterproof adhesive tape is processed into a wing shape, the two sides of the waterproof adhesive tape are provided with special-shaped buckles, and the length of each buckle edge is 2.5 cm. The waterproof rubber strips are processed in a factory, volume cutting is carried out according to the length of each expansion joint of the viaduct on site after the waterproof rubber strips are transported to a construction site, and the surplus length of the viaduct on site installation with the two sides accounting for 100cm in total is considered during cutting.
3. Positioning angle steel embedded at expansion joint
4. Installation waterproof adhesive tape
And after the welding of the reinforcing steel bar base on site and the embedding of the angle steel are finished, the waterproof rubber strip can be installed. The waterproof adhesive tape is easy to mount and the integrity of the adhesive tape is not damaged, so that the two sides of the waterproof adhesive tape are directly buckled to the vertical faces of the embedded angle steel and then fixed by stainless steel buckles, and the buckle interval is 60 cm.
