Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plate block for forming an upper plate of a bridge,

The present invention relates to a plate block for forming an upper plate of a bridge, and more particularly, to a plate block for forming an upper plate of a bridge, in which a plurality of plate blocks constituting a bridge upper plate are connected, To a plate block for forming an upper plate of the plate.

Generally, a bridge is composed of an upper structure and a lower structure alternately with a bridge, wherein the upper structure is made of a concrete structure or a steel structure.

In the case of a bridge composed of the steel structure, a plate block and a cross girder are provided to support the plate block.

Particularly, the upper plate of the bridge is composed of a plurality of plate blocks which are coupled to each other. Since the plate blocks are box-shaped and both ends thereof are clogged with each other, it is not easy to combine them.

Therefore, as shown in FIG. 1, it is difficult to fasten the bolt and the nut because of the closed space as shown in FIG. 1, but the fastened bolt and nut are inevitably exposed to the outside The structure is vulnerable to corrosion and the like, and thus the durability of the bridge is deteriorated.

As a result, various variations of the illustration, for example variations in the manufacturing method and / or specification, are expected. Thus, the embodiment is not limited to any particular form of the depicted area, but includes modifications of the form, for example, by manufacture. For example, the regions shown or described as being flat may have characteristics that are generally coarse / rough and nonlinear. Also, the portion shown as having a sharp angle may be rounded. Thus, the regions shown in the figures are merely approximate, and their shapes are not intended to depict the exact shape of the regions, nor are they intended to limit the scope of the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of a plate block for forming a top plate of a bridge according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 2 is a perspective view of a plate block of the bridge according to the present invention, FIG. 3 is a perspective view showing the combined state of FIG. 2, FIG. 4 is a cross- .

First, in the drawings, it is noted that the same components or parts are denoted by the same reference numerals as possible. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted so as to avoid obscuring the subject matter of the present invention.

The present invention is a plate block 110 that is connected to both ends of the plate block 110. The plate blocks 110 have ribs 113 and 114 spaced apart from each other in a longitudinal direction to reinforce the upper and lower plates, 113 and 114 are protruded to the outside of the support plate 112 formed at both side ends of the plate block 110 and the protruded reinforcing bars 113 and 114 are connected to each other at both ends of the reinforcing bars 113 and 114 of the adjacent plate blocks 110 And the coupling plate 115 and the fastening holes 116 and 117 are connected to each other by a pair of side stone projections 112a and lower stone projections 112b , And is configured to be located inside the closed space 111a formed by the cover 111, that is, not exposed to the outside.

That is, the pair of side stone projections 112a and the bottom stone projections 112b are formed at both ends of the plate block 110. When both ends of adjacent plate blocks 110 are abutted, And the state is open.

The worker joins the opposite ends of the reinforcing bars 113 and 114 of the adjacent plate blocks 110 through the open upper part with the engaging plate 115 and the fasteners 116 and 117.

Bolt holes are drilled in the both end portions of the reinforcing bars 113 and 114 so as to correspond to each other and a known fastening hole passing through the bolt holes of the coupling plate 115, 116 and the nut 117 as shown in Fig.

In the present invention, the plate block 110 supports the steel plate base material on the steel plate and is formed into a long and wide box shape by bending the steel plate base material into a square shape.

The reinforcing bars 113 and 114 are also referred to as ribs, and reinforce the upper and lower plates of the plate block 110. At this time, the upper plate supporting rib 113 is welded to the upper plate to support the lower portion of the upper plate, and the lower plate supporting rib 114 is welded to the lower plate to support the upper plate. .

When the coupling operation is completed, the operator can open the upper portion formed by the pair of side stone projections 112a and the lower stone projections 112b of the adjacent plate blocks 110 for sealing the closed space 111a And the cover 111 is closed.

A pair of side wall protrusions 112a and a bottom wall protrusion 112b of the plate block 110 abutting against the cover 111 are formed with a welded portion A to form a welded portion A, Thereby forming a space 111a.

Since the both ends of the reinforcing bars 113 and 114 and the coupling plate 115 and the fastening holes 116 and 117 are present in the completely enclosed closed space 111a, the portions are not shaken and eventually the bridges, Durability is improved.

The closed space 111a may be filled with various filling materials for more complete sealing.

For example, an epoxy excellent in bonding strength with a steel material, not shrinking well, and having excellent structural strength is the most preferable, but various filling materials such as urethane and the like which can be waterproof can be used.

Although the present invention has been described in connection with certain exemplary embodiments, it is to be understood that the present invention is not limited thereto and that various changes and modifications will be apparent to those skilled in the art. Various modifications and variations are possible within the scope of the appended claims.
