Description

The utility model relates to the upper structure of the railway track and can be used in the manufacture of elements of anchor joints used in the construction of high-speed trunk lines, lines with increased axial loads and high load-bearing strength.

Known anchor sealant having an external beveled surface, a central and two side jumpers and an inner surface for gripping the base of the head of the anchor, while the inner surface along at least two long sides is made with an inclination, forming a narrowing from the opposite side of the jumpers, and the outer side surface is inclined at an angle of 5-30 ° (see RF patent No. 45951, 06/10/2005).

The anchor sealant included in the tooling kit (described in the mentioned patent) covers the base of the anchor and serves to seal against leakage of cement mortar. The above anchor seal is intended for an anchor consisting of two heads connected by a jumper and two corrugated shanks (see RF patent No. 45951, 06/10/2005).

The sealant known from the above technical solution cannot be used for technological equipment of reinforced concrete sleepers, in which an anchor is used made of two brackets with a longitudinal cavity and a bridge, legs, and the upper part in the form of shelves with the formation of a pharynx between them with the possibility of placing a bridge in it ( see RF patent No. 109465, 10.20.2011).

An anchor sealant is also known (see RU No. 118314, ЕВВ 3/32, В28В 23/06, 07/20/2012) (the closest analogue). The technical result, which this utility model is aimed at, is to eliminate concrete leakage between the anchor and the tooling, as well as to reduce the wear of the sleeper tool itself in the manufacture of sleepers with an anchor according to the above technical solution. The specified technical result is ensured by the fact that the anchor sealant includes a “U-shaped closed shape” plate with an inclined outer surface for abutment to the sleeper and an inner surface for gripping the upper part of the anchor, while a sealing skirt is made around the entire perimeter, and on the part of the inner surface there is a horizontal shelf, and stiffeners are made along the entire perimeter of the plate between the outer and inner surfaces. In addition, the sealing skirt is located at an angle of 90 ° to the inner surface of the seal, and the seal itself is made of a polymeric material, for example, polypropylene. The design of the anchor seal allows you to reduce leakage of concrete mixture at the surface of the anchor, thereby reducing labor and time costs for removing smudges of concrete mixture on the finished sleeper.

However, the closest analogue is also not without drawbacks. Namely: the design of the known sealant does not completely preclude leakage of the concrete mixture at the surface of the anchor and concrete leaks between the anchor and the tooling.

The objective of the utility model is to eliminate this drawback.

The technical result is an increase in the sealed properties of the anchor seal and a reduction to the level of exclusion of leakage of concrete mixture at the surface of the anchor and concrete leaks between the anchor and the tooling

The specified technical result is ensured by the fact that the known anchor sealant includes a “U-shaped closed plate” with an inclined outer surface for abutment to the sleeper snap and an inner surface for gripping the upper part of the anchor, in which around the entire perimeter of the plate between the outer and inner surface stiffening ribs are made, and on the part of the inner surface - a horizontal shelf, according to the stated solution, around the entire perimeter of the inner and outer surfaces of the sealant anchor a sealing skirt made.

As you can see, the hermetic properties of the anchor seal are increased and the concrete mix leaks at the surface of the anchor and concrete leaks between the anchor and the tool to the level of exclusion is achieved by fulfilling the entire perimeter of the inner and outer surfaces of the anchor of the sealing skirt (the so-called “flashing”).

Below are graphical materials describing one of the possible embodiments of the utility model.

So, figure 1 schematically shows a General view of the seal of the anchor; figure 2 is a section aa in figure 1; figure 3 is a section bB in figure 1; figure 4 is a view In figure 2; figure 5 - node G in figure 3; figure 6 - node D in figure 2; in Fig.7 - node E in Fig.3; on Fig - schematically shows the placement of the seal with an anchor in the manufacture of reinforced concrete sleepers. In Fig.9, the implementation of the sealing skirt 6 of the seal is presented in the most clear and detailed form.

The anchor sealant consists of a “U-shaped closed shape” plate 1 with an inclined outer surface 2 for adhering to the sleeper shape (snap) 3 and an inner surface 4 for gripping the upper part of the anchor 5. The entire perimeter of the sealant, including the upper surface 4 a sealing skirt 6 is made, parts of the inner surface are a horizontal shelf 7. Along the entire perimeter of the plate 1, stiffening ribs 8 can be made between the outer surface 2 and the inner surface 4.

The sealing skirt 6 may be located at an angle of 90 ° to the inner surface 4 of the seal 1.

The sealant 1 may be made of a polymeric material, for example, polypropylene.

The following is an example implementation of a utility model.

In the manufacture of reinforced concrete sleepers (see Fig. 8), the anchor 5 seals 1 are installed in the prepared sleeper mold 3 (equipment) 5. The cap 10 is put on the bottom of the leg — the heel 9 of the anchor 5 and the anchor 5 is positioned in the sleeper mold 3 and in the seal 1. Clamp the anchor 5 with a pressure screw 11, resting against the cap 10. In the longitudinal direction of the sleepers, reinforcing elements (not shown) are pulled and the sleepers are poured with concrete mixture.

Next, the sleeper form is subjected to vibration and heat treatment. After the concrete mixture has hardened, the pressure screw 11 is removed, the sleeper comes out of the sleeper form, the cap 11 remains on the anchor inside the sleepers.

Then from the anchor 5 remove the seals 1, which are then disposed of. Thus, this design of the anchor seal allows you to minimize leakage of concrete mixture at the surface of the anchor, thereby reducing labor and time costs for removing smudges of concrete mixture on the finished sleeper.

As can be seen by the implementation of the utility model, an increase in the hermetic properties of the anchor sealant is achieved and a leakage of concrete mix at the surface of the anchor and concrete leakages between the anchor and the tool (to the level of exclusion) is achieved by fulfilling the entire perimeter of the inner and outer surfaces of the anchor sealant of the sealing skirt.
