Description
Technical field
The utility model is related to seal correlative technology field, the more particularly to sealing strip in a kind of field of sealing technology.
Background technology
Present Urban Underground walkway, cable passage etc. are laid with using prefabricated box culvert piping lane, and constructing in this way can be with
The duration is saved, is easily guaranteed that construction quality, reduces labour, while too big shadow will not be caused to urban transportation and civil plantation
It rings.Since box culvert piping lane is generally embedded in underground, if sealing is bad, underground water is easy to infilter box culvert, destroys in box culvert channel
Environment, the especially underground pipe galleries waterproof such as electric power box culvert pipe corridor seems extremely important, in this case, is used for building field
Sealing joint strip come into being.
Currently, the prefabricated pipe gallery interface in city if design it is at a right angle or if, existing sealing strip is due to structure
The reason of design, cannot effectively be bonded with piping lane bell and spigot, that is to say, that cannot effectively seal, when seal construction, along with assembly
The interference of the factors such as frictional force, construction are inconvenient.Therefore, it is based on this Industry, there is an urgent need for ask this puzzlement industry development
Topic specially devises a sealing strip.
Utility model content
Based on described above, the utility model aim is to provide that a kind of leakproofness is preferable, is suitable for right angle piping lane interface
Sealing strip, which reduces assembled frictional force while keeping preferable leakproofness, has the characteristics that easy for construction.
The utility model is realized by the following technical solutions：
Prefabricated pipe gallery right angle sealing strip, including elastic rubber ontology, the elastic rubber body cross-section is straight
The bevel edge stage casing of angle triangle, the right angled triangle is replaced by segmental arc.
Specifically, this weatherstrip body uses elastic rubber；Elastic rubber is due to superior elasticity, sealing strip size
Design achievees the purpose that sealing by compression factor, is more than the installation gap 15-60% of pipe gallery piping lane bellmouth and socket
Reaching outstanding seal pressure, the bevel edge stage casing of the elastic rubber ontology replaces by segmental arc, in this way, when seal construction,
Being applied to power on sealing surface makes elastic rubber ontology obtain the flexible deformation of bigger, is conducive to improve leakproofness.Further
The preferred embodiment on ground can also be further opened with round hole at the center of elastic rubber ontology, and the round hole is along elastic rubber
Body length direction runs through its first and last end.Further scheme is that the round hole is arranged at the right angle of right angled triangle
On bisector.
It is installed for the ease of assembly, self-lubricating material body is compounded in two sections of bevel edge sections being split to form by segmental arc, from
Lubriation material can select polyimides, polyether-ether-ketone, polytetrafluoroethylene (PTFE) it is one or more of or other.The self-lubricating effect
It can retain for a long time, when assembled in this way, convenient for overcoming frictional force, solve the problems, such as that construction is inconvenient when construction.
The utility model has the beneficial effects that：
The elastic rubbery body of right angled triangle makes the sealing strip can be according to the design feature of piping lane box culvert, spirit as ontology
It is embedded into livingly in the groove of piping lane interface；The bevel edge stage casing of elastic rubber ontology is replaced by segmental arc simultaneously, in this way, sealing is applied
Working hour is applied to power on sealing surface and elastic rubber ontology is made to obtain the flexible deformation of bigger, is conducive to the sealing for obtaining bigger
Than pressure value, leakproofness is improved；It is compounded with self-lubricating material body in two sections of bevel edge sections being split to form by segmental arc, the self-lubricating
Effect can retain for a long time, when assembled in this way, convenient for overcoming frictional force, solve the problems, such as that construction is inconvenient when construction.
Description of the drawings
Fig. 1 is the utility model cross-sectional structure schematic diagram.
Specific implementation mode
Below in conjunction with the accompanying drawings and specific implementation mode is described further the utility model.
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only explaining this
Utility model is not used to limit the utility model.
As shown in Figure 1, the utility model discloses a kind of prefabricated pipe gallery right angle sealing strip, including elastic rubber ontology
1,1 cross section of elastic rubber ontology is right angled triangle, is matched with piping lane interface right-angle side, the right angled triangle
Bevel edge stage casing replaced by segmental arc 2.
This weatherstrip body uses elastic rubber；Elastic rubber is since with superior elasticity, sealing strip size design is big
In the installation gap 15-60% of pipe gallery piping lane bellmouth and socket, sealing is achieved the purpose that by compression factor, in order to reach
The bevel edge stage casing of outstanding seal pressure, the elastic rubber ontology 1 is replaced by segmental arc 2, in this way, when seal construction, is applied
Power makes elastic rubber ontology 1 obtain the flexible deformation of bigger on sealing surface, is conducive to improve leakproofness.Further
Preferred embodiment can also be further opened with round hole 6 at the center of elastic rubber ontology 1, and the round hole 6 is along elastic rubber
1 length direction of ontology runs through its first and last end.Further scheme is that the round hole 6 is arranged in the straight of right angled triangle
On angular bisector.
It is installed for the ease of splicing, has self-lubricating material body 5 by upper 3 surface recombination of bevel edge section that segmental arc 2 is split to form；
Similarly, there is self-lubricating material body 5 by lower 4 surface recombination of bevel edge section that segmental arc 2 is split to form.Self-lubricating material body 5 can select
With polyimides, polyether-ether-ketone, polytetrafluoroethylene (PTFE) it is one or more of or other.The self-lubricating effect can retain for a long time,
When assembled in this way, convenient for overcoming frictional force, solve the problems, such as that construction is inconvenient when construction.
As another technical solution, the right angled triangle can have obtuse triangle replacement, but at this point, it is described
Segmental arc 2 should be arranged on the long side stage casing of obtuse triangle.
For this sealing strip in assembly, sealing surface is bevel edge and two right-angle sides, this sealing strip is as static seal, sealing strip
Initial compression that sealing function applies sealing strip is played along the bevel edge of sealing strip and the line direction of right-angle side.In this way,
On the one hand the segmental arc 2 being arranged on elastic rubber ontology 1 can effectively reduce sealing strip face area, in this way, when sealing strip
When height dimension is bigger than normal compared to the sealing groove height for installing sealing strip, when applying certain compression to sealing strip,
Compared to traditional sealing strip, this sealing strip can get the flexible deformation of bigger, in this way, may make this sealing strip more suitable
Profit is mounted in seal groove.Further, the above smaller face area is conducive to obtain the sealing of bigger on sealing surface
Than pressure, it may make this sealing strip that there is more preferable or more reliable sealing effect.
Above-described embodiment is the preferred embodiment of the utility model, is not the limit to technical solutions of the utility model
System, as long as without the technical solution that creative work can be realized on the basis of the above embodiments, is regarded as falling into
In the rights protection scope of the utility model patent.
