Description
Technical field
The utility model is specifically related to the special interior extended surface waterstop of Expansion Units for Highway Bridges.
Background technology
Rubber strip set by Expansion Units for Highway Bridges is the crucial body that forms a complete set of, with the combination of deformed steel and
Role, can directly influence the using effect of retractor device.Highway bridge was all installing a kind of with simple in the last few years
The retractor device that jagged deformed steel mounts V type rubber strips is driven, because processing mode is simple, groove and rubber strip can not form
Fixing seal state, almost all of retractor device all has " bad phenomenon " of rubber strip leak and local shedding.China
Vast in territory, the service condition of each department highway communication is widely different, particularly the south of the lower reaches of the Yangtze River and North China Plain area.Because of rainwater
The reason for excessive and silt is excessive, directly influences the normal operation of retractor device, most of local road science of bridge building is all pacified
The retractor device of thin tail sheep amount is filled, therefore maintenance rate and turnover rate are especially high, it has also become large, medium and small bridge
Engineering one is king-sized " operation burden ".
Utility model content
The purpose of this utility model is to stop to solve above-mentioned deficiency there is provided a kind of special interior extended surface of Expansion Units for Highway Bridges
Water band.
The purpose of this utility model is achieved through the following technical solutions：
The special interior extended surface waterstop of Expansion Units for Highway Bridges, including screw rod, nut, pad, pressing plate, sealing band body,
Erecting bed, sleeve and round steel, sealing band body are covered in erecting bed top, and the two ends of sealing band body are symmetrical set, left side
The right-hand member of pressing plate is arranged on the left upper part of sealing band body, screw rod by nut fixation clip on erecting bed, nut bottom
Pad is provided with, screw rod lower end is enclosed on sleeve inner, and the left end bottom of left side pressing plate is provided with round steel.
Sealing band body includes waterstop, and waterstop two ends head is in gibbosity form.
The base of sealing band body left and right ends is designed with three row's sealing lips.
Hard adhesive tape is provided with sealing band body two ends portion.
The utility model has following beneficial effect：
The utility model is reasonable in design, easy to use, the make extended out using inner support, utilizes the outer of rubber fastening band
The body function of arc convex surface and expansion connection strap, in the presence of expansion connection strap meets water expansion, promotes cylindrical arc convex surface to exist
Due pressure is formed in inner circle arc recess, possesses most reliable air-proof condition.
Brief description of the drawings
Fig. 1 is overall structure diagram of the present utility model；
Fig. 2 is waterstop body construction schematic diagram of the present utility model.
Embodiment
The utility model is further described below in conjunction with the accompanying drawings：
As depicted in figs. 1 and 2, the special interior extended surface waterstop of Expansion Units for Highway Bridges, including screw rod 1, nut 2, pad
3rd, pressing plate 4, sealing band body 5, erecting bed 6, sleeve 7 and round steel 8, sealing band body 5 are covered in the top of erecting bed 6, waterstop
The two ends of body 5 are symmetrical set, and the right-hand member of left side pressing plate 4 is arranged on the left upper part of sealing band body 5, and screw rod 1 passes through spiral shell
Female 2 fixation clips 4 are on erecting bed 6, and the bottom of nut 2 is provided with pad 3, and the lower end of screw rod 1 is enclosed on inside sleeve 7, left side pressing plate 4
Left end bottom be provided with round steel 8.
Sealing band body includes waterstop 9, and waterstop two ends head is in gibbosity form.
The base of sealing band body left and right ends is designed with three row's sealing lips 11.
Hard adhesive tape 10 is provided with sealing band body two ends portion.
Application method：Sleeve is embedded in concrete first, then lining type rubber fastening band, pressing plate and round steel put down
It is layered on erecting bed, is finally fixed and is fixed on lining type rubber fastening band with screw rod and nut using spiral marking connection mode
At immersed tube tube coupling gap, using the high resiliency of rubber, lining type rubber fastening band pressing plate one end is positioned, nut (moment of torsion is tightened
Set according to actual needs), nut promotes the other end of pressing plate to compress waterstop, so that active force is delivered to waterstop
Both wings, compress bottom 3 road sealing lips, reach hermetic seal effect.
