Abstract
The utility model provides a sealing structure of a ballastless track plate mold, comprising two adjacent molds provided with joint surfaces, wherein a rectangular sealing groove is arranged on the joint surface of one mold; and the sealing groove is embedded with a sealing rubber strip. The sealing rubber strip is a hollow lip-shaped sealing rubber strip. By adopting the hollow lip-shaped sealing rubber strip with excellent elastic property, the sealing performance of the joint surface of the mold is significantly improved, the anti-leakage performance and service life of the track plate mold can be effectively improved, and the product quality of the concrete ballastless track plate can be ensured.
Description
Technical field
The utility model relates to the mould of making the railway ballastless track plate, is specifically related to a kind of fragment-free track slab formwork seal structure.
Background technology
The concrete fragment-free track slab is to utilize mould to carry out concreting to form, and the combination quality of mould is had relatively high expectations, and wherein must not spillage during concreting is the basic demand to mould.Therefore the sealing effectiveness of each template faying face of non-fragment orbit board mold directly influences the quality of mould, also influences the service life of mould simultaneously.At present, the sealing of faying face between each template of concrete non-fragment orbit board forming die, the hermetically-sealed construction of Filled Rectangle or circular cross-section adhesive tape is inlayed in employing in groove, the sealing structure is because the elastic performance of sealing joint strip is poor, sealing effectiveness is not good, often, cause railway plate die spillage in the concreting forming process, influence the product quality of track plate and the service life of mould using back seal failure for several times.
Summary of the invention
The purpose of this utility model is at the problems referred to above, and the fragment-free track slab formwork seal structure of a kind of good sealing effect, long service life is provided.
The technical scheme that realizes above-mentioned purpose is: a kind of fragment-free track slab formwork seal structure, it comprises two adjacent templates with faying face, the faying face of a template is provided with the rectangular seal groove therein, be inlaid with sealing joint strip in sealed groove, its described sealing joint strip is hollow lip packing adhesive tape.
Above-mentioned hollow lip packing adhesive tape cross section is hollow trapezoidal, the lip mouth that places the sealing surface side by interior concaved circular cambered surface with place the adhesive tape knuckle of concaved circular cambered surface both sides in this to constitute.
The utility model adopts the good hollow lip packing adhesive tape of elastic performance, and the sealing property of template faying face is significantly improved, and can effectively improve the release-resistance energy and the service life of railway plate die, guarantees the product quality of concrete fragment-free track slab.
Description of drawings
Accompanying drawing is this fragment-free track slab formwork seal structural representation.
The specific embodiment
In conjunction with the accompanying drawings the specific embodiment of the present utility model is described.
As accompanying drawing, this fragment-free track slab formwork seal structure comprises two adjacent template 1 and templates 2 with faying face, and the faying face of template 1 is provided with the rectangular seal groove, is inlaid with hollow lip packing adhesive tape 3 in the sealing groove.Its hollow lip packing adhesive tape 3 cross sections are hollow trapezoidal, the lip mouth that places the sealing surface side by interior concaved circular cambered surface with place the adhesive tape knuckle of concaved circular cambered surface both sides in this to constitute.
Hollow lip packing adhesive tape of the present utility model 3 adopts top-quality rubbers to make, and the lip mouth of assembling back sealing joint strip is higher than gash depth, template in conjunction with the time faying face adhesive tape is applied certain pressure, the lip mouth is opened plays sealing function.
Claims (2)
1, a kind of fragment-free track slab formwork seal structure, comprise two adjacent templates with faying face, the faying face of a template is provided with the rectangular seal groove therein, is inlaid with sealing joint strip in sealed groove, it is characterized in that: described sealing joint strip is hollow lip packing adhesive tape.
2, fragment-free track slab formwork seal structure according to claim 1, it is characterized in that: described hollow lip packing adhesive tape cross section is hollow trapezoidal, the lip mouth that places the sealing surface side by interior concaved circular cambered surface with place the adhesive tape knuckle of concaved circular cambered surface both sides in this to constitute.
