Bridge exterior material installation structure {UNDER EXTERIOR PANEL ASSEMBLY STRUCTURE FOR BRIDGE}

The present invention relates to a structure for installing the exterior material for bridges, and in detail, the installation work on the exterior material is easy to block the lower area of the girder, which is the bridge structure, and the exterior material can be installed in a structure that can be stretched and contracted according to the temperature change between the girders. It is configured to be.

In general, structures such as overpasses and bridges installed in cities are installed, and these bridge structures have played an important role as the most convenient facilities in urban automobile communication.

However, these bridge structures have not been properly harmonized with the rapidly changing surrounding buildings due to urban redevelopment and remodeling, and as a result of the obstacles to urban environment and regional development, civil complaints are demanding removal.

In particular, most of the bridges in the downtown area are aging, and the image of urban landscape is degraded due to concrete white matter, leakage traces, and other stains. It was pointed out that it was dropped.

On the other hand, in recent years, in order to improve the problem of deterioration of aesthetics, attempts have been made to attach and install a separate exterior panel (blocking material) to the side and bottom of the bridge structure.

A structure for installing an exterior member on such a conventional bridge will be described with reference to the accompanying drawings.

1 is a schematic cross-sectional configuration diagram of a bridge according to a conventional bridge mounting structure, Figure 2 is an enlarged cross-sectional configuration of the main portion of Figure 1, Figure 3 is a cross-sectional configuration showing another embodiment of the conventional packaging material mounting structure. to be.

As shown in Figure 1 and 2, the conventional bridge exterior mounting structure has a plurality of bridges 100 is installed in the lower portion on the ground; A bridge bearing 200 provided on the pier 100; A plurality of girders 300 installed on the bridge bearing 200 to maintain a distance in the longitudinal direction; An upper slab 350 installed on the girder 300 to communicate with the vehicle; The lower panel of the girder 300 is assembled and maintained with the bracket 500 and the exterior member assembly member 600 to surround the bottom and side of the girder 300.

The bracket 500 includes a coupling part 511 coupled to the extension part of the lower part of the girder 300; An inclined coupling portion 512 inclined at the same angle at both ends of the upper portion of the coupling portion 511; A flange portion 513 formed to extend at the bottom of the coupling portion 511; It consists of a flange 513 and a horizontal finish plate 514 fastened and fixed by a bolt and a nut.

The exterior material assembly member 600 includes vertical length bolts 610 and 611 fastened and fastened vertically to the horizontal finish plate 524 by bolts and nuts; The heads of the vertical long bolts 610 and 611 are inserted and fixed, and the support frames 620 and 621 are fastened and fixed to extend the exterior panel 400 at the bottom thereof.

At this time, the exterior panel 400 is fastened and fixed to the lower portion of the support frame 620, 621 by a bolt, when the caulking (silicon) work on this portion, the bolting portion is concealed.

Therefore, the structure configured as described above uses a plate-shaped bracket to install an exterior panel installed in the lower girder, and thus, the assembly is not easy and the weight of the structure is large. It became.

In order to solve this problem, although not shown in the drawings, Patent Registration No. 10-0764418 (name of the invention: a concrete beam damage preventing exterior installation structure of the bridge) is provided with a bracket having a rectangular cross section, which is a concrete beam (girder) According to the expansion part of the) to manufacture integrally, or to install the exterior panel by drilling a hole, there is a problem that processing and assembly workability is reduced according to the manufacturing.

Meanwhile, as shown in FIG. 3, the exterior frame 700 is installed between a plurality of girders 300 spaced in the longitudinal direction on an upper portion of the bridge support 200 provided on the pier 100, so that the exterior of the girder 300 is provided. In order to block the connection site is connected using a square pipe 710.

The girder 300 is installed at intervals on the top of the bridge 100 in consideration of the displacement of the bridge in accordance with the temperature change.

The connection part of the girder 300 adopts a connection scheme using a welding or angle 730 and a fastening screw 740 to the square pipe 710. In this case, there is corrosion of the welded part, difficulty in field work, and the angle material cost and the work are not easy when the angle is assembled. In addition, in the case of bridges, temperature stretching occurs. Existing frames have a negative effect on the structure, such as frame deformation, because there is no way to put a separate expansion joint.
