Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the drawings, the same components are denoted by the same reference symbols whenever possible. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

As shown in the drawings, the method of constructing the railway bridge of the present invention starts with putting the support pile 10 in the ground. The support pile 10 is fixedly inserted between the bridge view point S and the bridge end point E at a distance from each other.

The support pile 10 may comprise a plurality of H beams 11 and a plate 13 covering the upper end of the H beams 11 (see FIGS. 5 and 6). The H beams 11 are arranged so as to form a square shape (for example, a rectangular shape) having a length of the embossed shape, and the embossing directions are displaced from each other to enhance the supporting force against the ground. The plate member 13 covers the upper end of the H beams 11 in the same rectangular shape as that of the H beams 11.

On each of the support piles (10), a transverse support (20) is fixedly installed. The transverse supports 20 are shaped to have a length and are fixed along the length of the plate 13, forming a transverse. The transverse support (20) is fixed to the plate body (13) so as to be detached and can be separated and assembled.

The longitudinal supports 30 are fixedly mounted on the transverse supports 20 and the longitudinal supports 30 are fixed across the transverse supports 20. The longitudinal supports 30 are lifted by a construction machine, such as a crane, with lifting hooks, and are stacked on the transverse supports 20, and may be arranged in two or more transverse supports 20. For example, the longitudinal supports 30 can be arranged in two or more bridges if they are long, and can be stacked on the transverse supports 20 in a single short bridge.

The longitudinal support 30 has a square-shaped structure in which the T-shaped support pieces 31 are arranged at a distance from each other. The longitudinal supports 30 can be formed by arranging the H beams on a bottom plate (not shown), which is a component, at a distance from each other through welding or the like to form the T-shaped supports. Walls 33 forming a receiving space for the railroad gravel 111 are formed on the vertical support rods 30 at the left and right sides of the vertical support rods 30, Can be installed.

The column support base 30 is provided with a metal plate body 60 having a resin body 50. The metal body 60 having the resin body 50 is fixedly detached between the support pieces 31 to cover the support pieces 31 with no gap therebetween. The resin body 50 is a structure having abrasion resistance, impact resistance, chemical resistance, elasticity, etc., and may be a mixture of two or more resins or two or more resins and a solid component. Such a resin body 50 absorbs and reduces the noise generated during the operation of the train, and alleviates impact and load, thereby improving the structural stability of the bridge.

For example, the metal plate bodies 60 may include a U-shaped receiving portion 61 and wing portions 63 extending horizontally from left and right ends of the receiving portion 61, respectively, and the resin bodies 50 May include a body portion 51 inserted into the receiving portion 61 and horizontal portions 53 extending horizontally from the left and right sides of the body portion 51 and positioned above the wing portions 63 .

The metal plate bodies 60 are installed between the support pieces 31 by mounting the wings 63 on the support pieces 31. When the installation of the metal plate bodies 60 is completed, The bottom of the resin bodies 50 is formed.

A protrusion 55 covering the inner wall surface of the wall bodies 33 of the vertical support base 30 may protrude from the body portion 51 and the horizontal portions 53. [ The projecting portion 55 covers the inner wall surface of the walls 33 of the vertical support table 30 to alleviate an impact or a load applied to the wall bodies 33 and reduce the noise.

The holding portion 61 of the metal plate bodies 60 may be provided with a fixing protrusion 65 positioned below the wing portions 63. [ The fixed protruding portion 65 may be formed on the left side or the right side or the left and right sides of the receiving portion 61. The fixing protrusions 65 are fitted under the horizontal head portions of the support pieces 31 composed of the vertical part and the horizontal head part to provide a place for fixing the metal plate bodies 60 to the support pieces 31.

For example, the brackets are pinched between the fixing protrusions 65 and the vertical portions of the support pieces 31, and the bolts are fastened to fix the metal plate bodies 60 to the support pieces 31 in a detachable manner. The fixing protrusions 65 perform a bracket function and are bolted to the vertical portions of the support pieces 31 to fix the metal plate bodies 60 to the support pieces 31 in a detachable manner. The fixing protrusions 65 may be bolted to the receiving portion 61 so as to be detachably attached thereto and the metal plate bodies 60 may be welded between the fixing portions of the fixing protrusions 65 and the vertical portions of the supporting pieces 31 However, construction and demolition are troublesome.

The metal plate bodies 60 are fixed between the support pieces 31 so that the bottom of the support members 30 is formed on the inner side of the vertical support table 30, The construction of the temporary bridge of the present invention is completed when the railway gravel 111 is laid on the railway gravel 111 and the railway gravel 111 is installed on the railway gravel 111 in order.

The surfaces of the body 51, the horizontal portion 53 and the projections 55 of the resin body 50 facing the railroad gravels 111 are provided with projections and depressions 57 such as an embossed shape, a horizontal or vertical shape, Can be formed. The irregularities 57 form irregular tangs and friction surfaces on which the railway gravel 111 is caught, thereby preventing sliding phenomenon of the railway gravel 111 which may occur when the train is operated.

In addition, the metal plate bodies 60 may be provided with fixing means 80 for fixing the resin body 50. The fixing means 80 is provided to penetrate the wing portions 63 of the metal plate bodies 60 and the horizontal portions 53 of the resin body 50 to separate the resin bodies 50 from the metal plate bodies 60 . For example, the fixing means 80 penetrates the wing portions 63 and the horizontal portions 53 with the bolt member 81, and then the nut member 83 is fastened to the resin body 50 Can be prevented from being separated.

As described above, according to the present invention, the support pile 10 is inserted between the bridge view point S and the bridge end point E, the transverse supports 20 and the vertical supports 30 are sequentially raised, The railroad gravel 111 and the railroad tie 113 and the rails 115 are sequentially installed after the metal plate body 60 having the resin body 50 is inserted between the support pieces 31 of the support rods 30, The construction and demolition of the bridge of the present invention are completed, so that it is convenient and can be repeatedly used. Further, the load bearing capacity of the metal plate body 60 is added to improve the structural stability of the bridge and due to the physical properties of the resin body 50 The noise is reduced and the load or impact is relieved, improving the structural stability of the bridge. In addition, the sliding phenomenon of the railway gravel 111 can be largely prevented by the unevenness 57 of the resin body 50. The metal plate body 60 having the resin body 50 is light and large, so that it is very easy to carry and store.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined by the appended claims. It will be possible. The scope of the present invention is defined by the appended claims, and all differences within the scope of the claims are to be construed as being included in the present invention.
