Abstract
The utility model relates to a compound pad for concrete sleepers, which is composed of an artificial board and a rubber layer. A plurality of through holes are arranged on the artificial board. The rubber layer is cast on the upper side, the left side, the right side, the front side, the back side, and the through holes of the artificial board. The utility model solves the problems of the existing rubber pad of low intensity, poor abrasive resistance performance, poor aging resistance performance, high cost, and short service life. Because of the large friction coefficient of the artificial board, the goal of skid prevention can be achieved without the antiskid grooves arranged on the contact surface of the artificial board and the concrete. So the utility model can be widely used as the compound pad for concrete sleepers having the advantages of simple structure and low cost.
Description
The utility model relates to the pad of iron sleeper.
Lay rail at present and extensively adopt concrete crosstie money, concrete crosstie is because the hardness height, poor flexibility, so must use good springiness with the joint portion of rail, have again on the material cushion of sufficient intensity and abrasion resistance, now widely used is rubber pad, rubber pad has good springiness, moulding advantage is easily manufactured in processing, but because this material cost height, compressive strength is low, abrasion resistance and ageing resistace are poor, especially in the winter time under the situation that temperature is low, rubber is met cold contraction, hardness strengthens, in the dislocation of very easily sliding of snowy weather, designed a kind of form of structure has several uniform non-slip grooves for the face that contacts with concrete at bottom surface rubber pad in order to address this problem people, this novel structure has solved sliding problem to a certain extent, but the new problem that produces is need spread fine flour sand snowy in the winter time season on rail, because passing by, train produces vibration in the above, thereby sand shakes inevitably to fall and enters anti-slip tank under the rail bolster, so very easily produce conquassation, destruction such as pulverize, Gu this, this rubber pad is very short application life.
Task of the present utility model is: design a kind of bottom surface at pad and do not offer non-slip groove and just have antiskid function, make it both have the elasticity that satisfies instructions for use, again than the gum pad gain in strength widely, abrasion resistance and ageing resistance, and rail bolster with characteristics of long service life.
Task of the present utility model realizes as follows: the rail bolster comprises a rectangular wood-based plate that has several through holes on it, on wood-based plate, the surface, left, right, front and rear is together with being cast with rubber layer in the through hole.
The utility model is owing to adopt wood-based plate and rubber combined forming, the face that contacts with concrete at wood-based plate need not left non-slip groove and can realize anti-skidding purpose like this, thereby simplify the structure, reduced cost, because pad adopts wood-based plate and the two-layer formation of rubber, so both had the elasticity that satisfies instructions for use, again than the gum backing plate gain in strength widely, abrasion resistance and ageing resistance, and have the characteristics of long service life.
Fig. 1 is the utility model vertical view;
Fig. 2 is the A-A sectional drawing of Fig. 1;
Fig. 3 is the B-B sectional drawing of Fig. 1;
Fig. 4 is the wood-based plate vertical view;
A most preferred embodiment of the present utility model, as figure, the structure of wood-based plate 1 as shown in Figure 4, its material can be selected wooden or non-wooden making for use, have several through holes on it, present embodiment is selected totally 9 of three rows, the center to center distance wood-based plate edge distance farthest in hole is 20mm, the diameter of through hole is 10mm, and the appearance and size of wood-based plate is 130 * 170, and thickness is 5mm, the thickness of rubber combined layer 2 is to have on its upper surface of 5mm at a distance of being the semicircle ditch of R1.5 for several radiuses of 25mm, rubber combined layer in the longitudinal direction to the left and right both sides rubber layer is arranged, as shown in Figure 2, be provided with supporting raised line seat in the bottom surface.
Claims (2)
1, a kind of concrete iron sleeper composite pad, comprise the rectangular body plate body, of the present utility model being characterised in that: rectangular slab have the wood-based plate of some through holes on it by one and on wood-based plate, the surface, left, right, front and rear constitutes together with the rubber layer of casting in the through hole, rectangle plate body soffit has the support strip seat.
2, composite pad as claimed in claim 1 is characterized in that: the thickness of said wood-based plate equates with the thickness of rubber layer.
