Technical field

The invention belongs to bridge extension joint technical fields, and in particular to a kind of integrated drainage system of telescopic device.

Background technique

Bridge extension joint be in order to so that vehicle is smoothly passed bridge floor and meet bridge superstructure deformation needs, in bridge The general name for the various devices of the flexible place's setting of beam being made of components such as rubber and steel, it is mainly by power transmission supporting system and position Control system composition is moved, major function is first is that vertically and horizontally load by supporting structure is transmitted to beam body by vehicle, second is that fitting Answer the variation that bridge is displaced in length and breadth and the corner variation that beam-ends warpage occurs.When rainy, bridge lateral lowest part often Ponding causes silt that cannot be discharged in time, so that telescopic device is in wet environment for a long time, easily makes telescopic device steel structure Part corrosion causes irreversible lesion to telescopic device, reduces service life.

Summary of the invention

In order to solve the problems, such as it is above-mentioned cannot be discharged in time in bridge lateral lowest part ponding, poly- sand, the present invention provide one Kind telescopic device integrates drainage system.

Telescopic device of the present invention integrates drainage system, including telescopic device, is arranged in the one of telescopic device top Castellated plates to contactless misfit and the band that catchments below castellated plates；

The telescopic device includes several waterstops for being spaced beam body side by side and being arranged between adjacent beam body, in the beam body Top is developed across the depressed area of several beam bodies, and the waterstop ends in the depressed area, the tooth form of the phase misfit Plate is arranged in depressed area, and each castellated plates include rack gear and the toothholder that is connected with rack gear, and two toothholders are installed in the side of two sides respectively Liang Shang；

The lower section in adjacent beam body and being located at waterstop, depressed area is arranged in the band that catchments, and length is greater than the width of depressed area, Band both ends catchment for one end high and another end low, the low and middle-end drainage system existing with bridge is connected.

In order to keep the continuity of bridge floor, the thickness of castellated plates and the height of depressed area are equal.

In order to increase collecting water from runoff, the cross section of the band that catchments is in bowl-type.

The utility model has the advantages that the present invention has amputated the depressed area of waterstop by being arranged on bridge extension joint top, and recessed It falls into area and contactless misfit castellated plates is set, while the band that catchments is set in castellated plates lower part, the ponding of rainy day is enable to be discharged rapidly Bridge avoids silting, reduces the time that telescopic device is in wet environment, extends the service life of telescopic device；It is logical It crosses and is arranged to the thickness of castellated plates equal with the height of depressed area, make that road surface is coherent beautiful, safety；Pass through the cross for the band that will catchment Section is arranged to bowl-type, increases collecting water from runoff, ponding can be discharged rapidly in the rainy day.

Specific embodiment

Technical solution of the present invention is described in detail below by attached drawing, but protection scope of the present invention is not limited to The embodiment.

Include telescopic device, be arranged on telescopic device as shown in Figure 1-3, telescopic device of the invention integrates drainage system A pair of of castellated plates of the contactless misfit in portion and the band 5 that catchments below castellated plates.

The telescopic device includes that several interval deformed steel beam bodies 6 side by side and the rubber being fixed between adjacent beam body are prevented Water band 4.It is located at the position of deck transverse slope lowest part (i.e. at emergency stopping lane only anti-collision wall) for several beam bodies 6 in the telescopic device The depressed area for being developed across several beam bodies 6 is cut on top, and the depth of cutting includes the position where the waterstop 4, thus Waterstop 4 ends in the depressed area.

The castellated plates setting is deformed steel the first castellated plates 1 and the second tooth of contactless misfit in the depressed area Shape plate 2, the first castellated plates 1 include toothholder 11 and the rack gear 12 being connected with toothholder 11, and the second castellated plates 2 are also the same, two toothholders point It is not welded on the side bar 3 of telescopic device two sides.It is contactless state when the rack gear misfit of two castellated plates, material is thus formed seams Gap, rainwater can enter and then be discharged from gap when the rainy day.

The band 5 that catchments is rubber product, is bonded in adjacent beam body and is located at the lower section of waterstop 4, depressed area, show So, the band 5 that catchments can also be fixed by other means, such as be fixed in adjacent beam body using fixing components such as bolts.It catchments Length with 5 is greater than the width of depressed area, and 5 both ends of band of catchmenting are set as one end high and another end low, and low side is existing with bridge Drainage system be connected.After being arranged in this way, the band 5 that catchments can collect the water for flowing into castellated plates and water from waterstop 4 logical Cross the drainage system discharge bridge of bridge.

As Figure 2-3, the band 5 that catchments is shown consideration for along adjacent beams closes setting, and cross section is in bowl-type, can be increased in this way Ponding can be discharged rapidly in the rainy day in collecting water from runoff.

As shown in figure 3, the thickness of castellated plates is arranged to it is equal with the height of depressed area, using this structure, Ke Yibao It holds the coherent, beautiful of bridge floor and ensures safety.

In actual use, in the rainy day, rainwater can converge in deck transverse slope lowest part, pass through the sky between a pair of of castellated plates Gap enters the band 5 that catchments, and the water for being simultaneously from the waterstop 4 at depressed area both ends, which also converges to, to catchment on band 5, from the band 5 that catchments Low side enters the existing drainage system of coupled bridge and bridge floor is discharged in rainwater.In this way, rainwater deck transverse slope most The accumulation time of lower greatly reduces, while the rainwater being discharged also can smoothly take away silt, reduce the dampness of telescopic device Time improves service life.

As described above, must not be explained although the present invention has been indicated and described referring to specific preferred embodiment For the limitation to invention itself.It without prejudice to the spirit and scope of the invention as defined in the appended claims, can be right Various changes can be made in the form and details for it.
