Description
Technical field
The utility model belongs to bridge expansion joint installation technical field, and in particular to a kind of bellows bridge expanssion joint sealing
Band.
Background technology
Prior art bridge expanssion joint waterstop uses solid rubber waterstop, although with certain water-stagnating effect,
It is that caused all kinds of road garbages are not easily cleaned during use；And after vehicle rolls repeatedly, rubbish is more closely knit, clearly
Manage difficulty to increase, considerably increase the workload and potential safety hazard of cleaning work personnel.
Utility model content
The purpose of this utility model is to overcome defect present in above-mentioned prior art and provide a kind of bellows bridge and stretch
Waterstop is stitched, using air negative pressure caused by automobile traveling, rubbish is realized automatic cleaning, expansion joint and waterstop is persistently protected
Cleaning is held, cleaning is convenient, considerably increases the safety of cleaning work personnel.
The purpose of this utility model is achieved through the following technical solutions：
A kind of bellows bridge expanssion joint waterstop, including bellows waterstop, it is arranged at filling at the top of the bellows waterstop
Valve；The bellows waterstop includes upper capsule band, lower capsule band, the center sleeve surrounded by the upper capsule band and lower capsule band closure.
As further improvement of the utility model, the both ends of the bellows waterstop are arranged on two and stretched relative to bridge
Contracting is stitched in symmetrically arranged shaped steel.
As further improvement of the utility model, the both ends of the bellows waterstop and two notch junctions of shaped steel
It is provided with rubber-metal bonding agent layer.
As further improvement of the utility model, the bellows waterstop in the deflated condition, the upper capsule band and institute
Gap is less than 0.03mm between stating shaped steel.
As further improvement of the utility model, the center sleeve passes through charging connector and ft connection.
Bellows bridge expanssion joint waterstop of the present utility model, has the advantages that：
（1）Bellows waterstop, in use, to middle airbag aeration to certain pressure, make capsule band and shaped steel it
Between gap be less than 0.03mm, upper capsule band is heaved slightly, bellows waterstop is sealed bridge expanssion joint even closer, effectively keeps away
Exempt from the rubbish such as dust gravel and dropped to be clogged to inside bridge expanssion joint and influence the normal use at expansion joint；
（2）When carrying out garbage-cleaning to bellows waterstop, the supreme capsule band of middle airbag aeration need to be only heaved to maximum journey
Degree, and directly clean or pat, it is necessary to be gone out garbage-cleaning with waddy when overcoming traditional waterstop progress garbage-cleaning
Come, significantly reduce the work load of staff, cleaning is convenient, and improves the safety guarantee of staff；
（3）When without garbage-cleaning, center sleeve is also at inflated condition, is born using air caused by automobile traveling
Pressure, dust gravel and Other Waste etc. are taken away automatically, reaches the effect cleared up automatically, expansion joint and waterstop is persistently kept
Cleaning；
（4）Will rubber-metal bonding agent layer be set between bellows waterstop and shaped steel notch, improves the sealing at expansion joint
Energy, improve the water resistance at expansion joint.
Brief description of the drawings
Fig. 1 is the structural representation under the utility model center sleeve unaerated state；
Fig. 2 is a kind of using state structure diagram of the utility model；
Fig. 3 is the utility model another kind using state structure diagram.
Wherein：Capsule band, 3-2- center sleeves, the upper capsule bands of 3-3-, 4- under 1- shaped steel, 2- notches, 3- bellows waterstop, 3-1-
Charging connector.
Embodiment
To enable feature and advantage of the present utility model more obvious understandable, below in conjunction with the accompanying drawings with specific embodiment pair
The utility model is described in detail, but the utility model can also use other be different from accompanying drawing and it is described here its
Its mode is implemented, and the embodiment is only preferred embodiment, rather than whole embodiments, should not to protection of the present utility model
Scope plays restriction effect.Those skilled in the art can do similar popularization in the case of without prejudice to the utility model connotation,
On the basis of no any performing creative labour, any modification or change that are carried out to the utility model, it is deemed to fall
In the range of the utility model protection.
A kind of bellows bridge expanssion joint waterstop of the present utility model as Figure 1-3, including bellows waterstop 3, set
It is placed in the charging connector 4 at the top of bellows waterstop 3；The bellows waterstop 3 includes upper capsule band 3-3, lower capsule band 3-1, by institute
State the center sleeve 3-2 that capsule surrounds with 3-3 and lower capsule with 3-1 closures；The one end of charging connector 4 connection center sleeve 3-2；Institute
State center sleeve 3-2 and pass through charging connector 4 and ft connection.
The both ends of the bellows waterstop 3 are arranged on two relative in the symmetrically arranged shaped steel 1 of bridge expanssion joint；It is described
The both ends of bellows waterstop 3 are provided with rubber-metal bonding agent layer with two junctions of notch 2 of shaped steel 1, improve expansion joint
Sealing property, improve the water resistance at expansion joint；Rubber-metal bonding agent layer can use BD803 rubber-metal bonding agents
（High intensity）Or BD804 rubber-metal bonding agents（Enhanced water resistance）, BD802 rubber-metal bonding agents（150 DEG C of high temperature resistant）, root
Different binding agents is selected according to concrete condition.
As shown in Fig. 2 controlling degree of inflation during the utility model use, make the upper capsule band 3-3 and the shaped steel 1
Between gap be less than 0.03mm, capsule band is heaved slightly, the state is the normal use state of waterstop, makes bellows waterstop
Bridge expanssion joint is sealed it is even closer, effectively avoid the rubbish such as dust gravel drop be clogged to inside bridge expanssion joint and
Influence the normal use at expansion joint；In addition, under the state, air negative pressure caused by automobile traveling can be utilized, by dust gravel
And Other Waste etc. is taken away automatically, reach the effect cleared up automatically, cleaning is convenient, makes bellows waterstop persistently keep cleaning.
As shown in figure 3, controlling degree of inflation in the utility model scale removal process, make the upper capsule band 3-3 and the shaped steel 1
Between gap be less than 0.03mm, and upper capsule band is heaved at utmost, and the state is state when clearing up rubbish on waterstop
Schematic diagram, now, staff only need directly to clean or pat, and when overcoming traditional waterstop progress garbage-cleaning, need
Garbage-cleaning is come out with waddy, significantly reduces the work load of staff, and improves the safety of staff
Ensure.
