Description

Vibration-absorbing rubber mat combined concrete sleepers {omitted}

The present invention relates to a vibration buffer rubber mattress concrete sleeper that mitigates vibration noise pollution during train operation.

More specifically, waste tire powder rubber, synthetic rubber, reticulated fiber filler, thermosetting adhesive, anti-aging agent, and ultraviolet absorber are formulated in the mold mold to reduce vibration shock noise generated when driving a train. The present invention relates to a vibration damping rubber mat-bonded concrete sleeper having good strength and elasticity, which is integrally molded by heating and pressing the vibration damping rubber mat into a concrete sleeper mold (not shown here).

Generally, wood and concrete sleepers are commonly used as train sleepers, and in some cases, only rubber cushions are independently installed between sleepers and sleepers.

The applicant has filed a utility model registration application No. 20-2001-0003845 steel structure body and resin non-bonding sleepers

With the development of trains and subways, many tracks have been established, but conventional concrete sleepers have many problems, such as noise pollution and cracks in concrete structures due to vibrations of vehicles that run due to insufficient buffering effects due to poor vibration damping capacity. have

The purpose of the present invention is that conventional sleepers absorb vibration shocks while they are being trained and are directly transmitted to concrete structures and piers on the road, resulting in crack and noise pollution.

The present invention combines automobile waste tire powder rubber, synthetic resin, thermosetting adhesive, reticular DC filler and anti-aging agent in the ratio of tensile strength and elasticity that can be used for mixed concrete sleepers. The mat is formed by heating and pressure molding, and this mat is installed at the bottom of the sleeper mold. The mattress-shaped protrusion formed on the vibration buffer rubber mat is bound to the concrete. There is no fear that the mats will stick together and fall off

When the sleeper with good strength and elasticity is installed in the train furnace, the vibration damping rubber mat is installed between the concrete structure and the sleeper to alleviate the vibration of the running train to prevent noise pollution and prevent cracking of the concrete furnace surface. can do

1 is a detailed explanatory view of the partial incision of the present invention

First (A). Is a partial cutaway plan view of the present invention.

In order to solve the above problems, the present proposal is to form the electric shock-absorbing rubber mat 10 is integrally combined with concrete in the sleeper manufacturing mold (not shown here) when manufacturing the concrete sleepers (A).

When described in detail the configuration and operation of the present invention by the accompanying drawings as follows.

As shown in Figure 1, the concrete sleeper (A) of the present invention, the skeleton steel structure body (1) to form a sleeper left and right in one sleeper. One type is installed, and the lower part is formed with protrusions (2) to increase the strength of the concrete sleepers in the protrusions are formed a plurality of reinforcing holes (2A) are inserted into the reinforcing bars (3) to fix the strong sleeper The steel structure is completed

The upper plane of the steel structure body (1) is a furnace fixing groove (5) for installing the furnace 8 of the train and a projection jaw (1A) for holding the furnace and the fixing plate for fixing the furnace in front ) And two fixing screw holes (4) for fastening the fasteners (7) and the fixing plate (6) mentioned above.

And the vibration buffer rubber mat 10 is composed of a mushroom-shaped protrusion (11) and the projection jaw (12)

As shown in Fig. 2 and Fig. 2 (A), waste tire powder rubber, reticular fiber filler, thermosetting adhesive, stabilizer, synthetic resin, rubber absorber, antioxidant, etc. are formulated in a ratio suitable for strength and elasticity. (Not shown here) by pressurized molding with high pressure

Deliciously molded into a concrete sleeper (A) mold (not shown here)

The lower part is deliciously flat on the structure of the road surface, and in order to increase the strength and elasticity in the manufacture of the vibration damping rubber mat 10, the mesh-like fiber 10A is formed in mat manufacturing and the upper plane is bound to the concrete 26 The mushroom-shaped protrusions 11 and the projection jaw (12) is formed

And left and right. Finally, the fixing holes 25 necessary for fixing the sleepers are penetrated.

In addition, this hole is fixed to the mold by fixing holes 25 even when the vibration damping rubber mat 10 is inserted into the concrete sleeper mold (not shown here). The vibration damping rubber mat 10 is integrally formed so that the hole is penetrated.

In addition, the concrete sleeper (A) upper spring seat 21 is composed of a spring seating groove 22, a buffer spring 23, two knots 24, a fixing bolt 24A and a spring washer (24B) A shock absorbing spring (23) is seated on one spring seat (21), and a fixing nut (24), a fixing spring washer (24B), and a fixing nut (24) are doubled on the upper part of the fixing bolt (24A). When rubber mat bonded concrete sleeper is installed on road surface concrete structure, sleeper buffers when vibration of train

As described above, according to the present invention, the vibration damping rubber mat 10 is attached to the lower part of the concrete sleeper installed under the track of the train and is integrated with the concrete. It reduces the cracks and does not overwhelm the sleeper by vibrating buffering effect, which has the effect of lengthening the sleeper and road surface structure
