Description

[0001] PILE FIXED TYPE RAILWAY SOUNDPROOF STRUCTURE [0002]

The present invention relates to a railway soundproofing wall, and more particularly, to a pile fixed railway soundproofing wall for facilitating the construction of a soundproofing wall facility by allowing the lower portion of the soundproofing wall to be supported by a pile structure.

Generally, a sound barrier for absorbing and blocking friction noise and aerodynamic noise due to friction between wheels and rails of a railway vehicle is installed at the railway where the railroad runs.

As a conventional example of such a railroad soundproof wall, a technique related to a railroad near soundproof wall has been proposed in the Utility Model Registration No. 475822.

However, in the above-mentioned prior art, since the concrete slab is to be installed at the lower part in order to stably support the sound barrier, there is a problem that the construction period and cost are increased in the process of installing the sound barrier.

The present invention has been proposed in order to solve the problems in the prior art described above, and it is possible to change the lower support of the railway soundproof wall from the existing concrete slab to the fixed form of the pile so that the construction of the railway soundproof wall can be made quicker and easier The purpose is to make sure.

According to an aspect of the present invention, there is provided a railway soundproofing wall comprising: a stationary pile fixedly installed at a predetermined interval along a railway; A file cap coupled to an upper portion of the fixed file; A duct frame installed at both ends to connect between the file caps; A first hinge plate having a bolt fastened on the top of the pile cap; A soundproof wall that is seated and supported on the upper portion of the duct frame; And a second hinge plate formed below the holding beam of the sound barrier for coupling with the first hinge plate.

The present invention is applied to a pile fixing type that does not require a concrete pouring operation for supporting a lower portion of a railway soundproofing wall, so that the construction of a railway soundproofing wall can be performed more quickly and easily.

Also, since the assembly and disassembly of the components for coupling with the soundproof wall supports can be easily performed, it is possible to reduce the maintenance cost of the facilities and to improve the working efficiency.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, the installation structure of the fixed railway type soundproof wall according to one embodiment of the present invention will be described.

A file cap 20 is coupled to an upper portion of the fixed file 10 fixedly installed in a vertical direction on the ground surface at regular intervals along a railway line and a duct frame 30 for guiding wiring is provided between the file caps 20 Respectively.

A first hinge plate 40 for fixing the strut beam 110 is fixed to the upper portion of the pile cap 20 between the opening flange portions 22 of the pile cap 20 and the support plate 60, (45).

The first hinge plate 40 is seated on the upper surface of the opening flange portion 22, and the first hinge plate 40 is seated on the upper surface of the opening flange portion 22 The first hinge plate 40 and the support plate 60 are compressed and coupled by the fastening bolts 45 while the support plate 60 is provided on the bottom surface of the opening flange 22. [

The second hinge plate 50 is fastened to the first hinge plate 40 by the fastening bolt 45 while the second hinge plate 50 is fixed to the lower end of the holding beam 110 by welding or by a piece. The connection is made.

Particularly, the first hinge plate 40 is formed at one side thereof with an inclined portion 41 inclined at a predetermined angle, and the inclined portion 41 is formed with a square through hole 42, A vertical part 52 to be inserted into the through hole 42 and a horizontal part 51 for pressing and supporting the inclined part 41 are integrally provided at one side of the guide part 50, .

A bolt hole 21 is formed on the bottom surface of the pile cap 20 so that the bolt portion 11 can be fastened. It can be confirmed that this is formed in the form of a long hole.

The operation and effect of the construction and installation of the fixed railway soundproof wall of the present invention having the above-described structure will be described.

When the fixing pile 10 is stuck at predetermined intervals along the side of the railway where the soundproof wall 100 is to be installed, the bolt portion 11 exposed on the upper side of the fixing pile 10 is fitted with the pile cap 20 The bolt hole 21 is inserted and fixed.

At this time, both end portions of the duct frame 30 having a predetermined length are connected to each other between the pile caps 20. The duct frame 30 is connected to the bolt portion 11 fastened to the pile cap 20, Only to the position where it is not realized.

At this time, the second hinge plate 50, which is coupled to the lower end of the strut beam 110, is fixed to the top of the pile cap 20, The first hinge plate 40 and the fastening bolt 45 are fastened to each other.

The vertical part 51 formed at one side of the second hinge plate 50 is inserted into the through hole 42 formed in the first hinge plate 40 and the horizontal part 52 is inserted into the first hinge plate 40, So that a stable engagement state can be maintained between them.

When the installation of the support beam 110 is completed, the soundproof wall 100 is sandwiched between the support beams 110 so that the soundproof wall 100 can be seated on the duct frame 30, Is completed.

Accordingly, it can be seen that the present invention can be applied to a railway soundproof wall more quickly and easily because a fixed form in which a concrete pile is supported by a fixing pile 10 is applied to support a lower portion of a railway soundproof wall have.

Particularly, since the first and second hinge plates 40 and 50 and the support plate 60 for coupling with the sound barrier wall support can be easily assembled and disassembled, the replacement work can be easily performed when the sound barrier wall is partially damaged Thereby reducing the maintenance cost of the facility.
