Description
Technical field
The utility model relates to a kind of grouting of prefabricated board to cover, and belong to vibration abatement field, be specifically related to a kind of cushion blocking
Prefabricated board grouting set.
Background technique
The effect of railway roadbed cushion blocking is vibration and the noise cut down or be isolated on the basis of being transmitted to when train passes through, and current
The installation of prefabricated board cushion blocking when process is many and diverse, heavy workload, maintenance replacement are difficult.
It is precisely firm that rubber should ensure to assemble with prefabricated board, takes into account elastic damping demand again, this is that rubber package set exists
Unavoidable significant problem in application process.If single selection rigidly bolts, the elastic damping effect of entire jacket certainly will be big
It gives a discount；If being bonded only with adhesive, adhesive hydrolysis, the problems such as bonding force is insufficient, which are also possible to become jacket system, is lost
The inducement of effect must be solved thoroughly.
For this purpose, the designer of the utility model is in view of the foregoing drawbacks, by concentrating on studies and designing, it is comprehensive it is long-term for many years from
The experience and achievement of thing related industry, researching and designing goes out a kind of cushion blocking prefabricated board grouting set, to overcome drawbacks described above.
Utility model content
The utility model is mainly to solve technical problem above-mentioned present in the prior art, and it is pre- to provide a kind of cushion blocking
Making sheet grouting set.The cushion blocking prefabricated board is in the milk, and nested structure is simple, and manufacture convenience, easy for installation, wearability is good, service life
Long, the shape and specification of sleeve can be adaptable according to requiring to make adjustment.
Above technical problems of the utility model are mainly solved by the following technical scheme:
A kind of cushion blocking prefabricated board grouting set, comprising:
Outwardly extending overlap edge along the horizontal plane is arranged in sleeve body, bottom end, several ring-types are arranged on lateral wall
Flange；
Wherein, the projected area of the overlap edge in the horizontal plane is greater than the perspective plane of the sleeve body in the horizontal plane
Product, the collar flange are arranged successively with non-different interval along the axial direction of sleeve body.
In at least one embodiment of the present invention, the collar flange is divided at least two groups by thickness, kind of thickness compared with
The small side for being located remotely from the overlap edge.
In at least one embodiment of the present invention, the overlap edge is round or rectangle.
Therefore, the utility model has the advantages that
1. grouting set is assemblied in the grouting hole site of road bed board, bottom end skirt is bonded with the edge of bottom plate, top with it is prefabricated
Plate upper face is concordant；
2. during pouring construction, the isolation of grouting set, the inner cavity environment for sealing whole rubber package set, avoid concrete into
Enter jacket inner cavity and occupy deformation space, and then influences the effectiveness in vibration suppression of whole system；
3. playing buffer shock-absorbing between prefabricated board and the big rigid body of limited post two in the operation phase that is open to traffic；
4. raw rubber selects SBR, NR etc., cooperate the basic material system of high abrasion, has that breaking strength is big, tearing strength is high
The excellent feature with wearability adapts to the casting grouting construction work that a large amount of concrete slurries are poured by grouting set completion in the process
Make environment.
Detailed description of the invention
Fig. 1 shows a kind of signal of the embodiment of solid concrete roabed cushion blocking prefabricated board grouting set of the utility model
Figure.
Fig. 2 shows a kind of assembling schematic diagram of solid concrete roabed cushion blocking prefabricated board grouting set of the utility model.
In figure, grouting set 1, sleeve body 2, overlap edge 3, collar flange 4, concrete prefabricated board 5, bottom plate 6.
Specific embodiment
Below with reference to the embodiments and with reference to the accompanying drawing the technical solutions of the present invention will be further described.
Embodiment:
Referring to Fig. 1, it is shown that a kind of signal of solid concrete roabed of the invention embodiment of cushion blocking prefabricated board grouting set
Figure, grouting set 1 are hollow tube-shape, and grouting set 1 includes sleeve body 2, and the bottom position of sleeve body 2 is provided with a thickness
Uniform overlap edge 3 is spent, several collar flanges 4 extended outward by sleeve body 2, the ring are provided with above overlap edge 3
The contact area of sleeve and prefabricated board hole wall when the setting of shape flange can not only reduce installation reduces installation resistance, can be with
The position between grouting set generated due to self gravitation effect or application load after buffering prefabricated board integral hoisting or grouting
Shifting amount.
The bottom position of sleeve body 2 is provided with an overlap edge, and the rubber compound of ingredient of the same race is used with sleeve body, and
It can be realized synchronic curing molding.Several collar flanges extended outward by sleeve body 2 are provided with above overlap edge 3
4。
As a preferred mode, in the present embodiment, positioned at a few 4 lower halfs of place's collar flange of cylinder top half
It is point narrow, with convenient for assembly.
Mainly there are two aspect effects for the setting of flange 4: one is reducing the contact surface with prefabricated board hole wall during installation
Product reduces installation resistance, drops out convenient for being packed into grout hole and not falling off；Secondly pre- after completing integral hoisting or grouting
When making sheet self gravitation effect or application load, there is certain displacement to act between prefabricated board and grouting set, which can buffer
The displacement.
The bottom position of sleeve body 2 is provided with an overlap edge, and the shape and thickness of the overlap edge can according to need
It is adjusted, the rubber compound of ingredient of the same race is used with sleeve body, and can be realized synchronic curing molding.
Referring to fig. 2, it is shown that a kind of solid concrete roabed of the invention assembling schematic diagram of cushion blocking prefabricated board grouting set fills
Slurry set is assemblied in the grouting hole site of road bed board, after installing end plate, grouting set with side top down from bottom plate
Formula fills in prefabricated board grout hole, and bottom end skirt is bonded with the edge of bottom plate, and top is concordant with prefabricated board upper face.
As can be seen from the above description, the utility model has the effect that 1. grouting sets are assemblied in the grout hole of road bed board
Position, bottom end skirt are bonded with the edge of bottom plate, and top is concordant with prefabricated board upper face；2. during pouring construction, grouting
Set isolation, the inner cavity environment for sealing whole rubber package set avoid concrete from entering jacket inner cavity and occupy deformation space, and then influence
The effectiveness in vibration suppression of whole system；3. playing buffering in the operation phase that is open to traffic between prefabricated board and the big rigid body of limited post two and subtracting
Bestir oneself use；4. raw rubber selects SBR, NR etc., cooperate the basic material system of high abrasion, has that breaking strength is big, tearing strength is high
The excellent feature with wearability adapts to the casting grouting construction work that a large amount of concrete slurries are poured by grouting set completion in the process
Make environment.
The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute
Belonging to those skilled in the art can make various modifications or additions to the described embodiments or using similar
Mode substitute, but without departing from the spirit of the present application or beyond the scope of the appended claims.
