Description

{Bridge supported by iron strip girder and elastic plate}

The present invention relates to a bridge, and more particularly, to a bridge capable of ensuring structural stability while ensuring ease of installation by connecting an iron plate strip girder and an elastic plate.

The limb is a bridge connecting the valleys and the hills between rivers, and is also useful for the establishment of a hiking trail. As shown in Fig. 5, the limbs, which are classified as one type of suspendable legs, are arranged so that the weight of the legs including the upper plate 50 and the legs And support the passing load of the pedestrians who use it.

However, since the roof bridge of such a structure is required to connect the main tower with the cable as the auxiliary cable after placing the top board at a predetermined vertical height with the cable between the main tower and the main tower connected thereto, It is very tricky. In addition, such a construction method requires a somewhat wide construction site, and it is very difficult to secure a construction site in reality because it is mainly installed in a mountainous area where transportation of materials is inconvenient.

In addition, since the conventional limb supports all the loads acting on the legs as a cable, the legs swing to the left or right or up and down according to the pedestrian behavior on the top plate, Failure to observe this may result in a safety hazard. In addition, since the conventional limb is structurally characterized in that cables do not have a structure capable of absorbing and dispersing the external force which is merely supported by the upper plate, when the external force is accumulated in the limb due to the passage of the pedestrians for a long time, There is a problem that the structural stability is seriously impaired.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the technical features of the present invention, A detailed description thereof will be omitted.

FIG. 1 is a schematic side view of a bridge according to the present invention, and FIG. 2 is a schematic structural view of a steel plate strip girder and a top plate in a bridge according to the present invention. As shown in the drawings, the present invention is directed to an alternating 10 and bridge 20, an elastic plate 30 and a steel strip girder 40, a beam 50 and a string 70, a railing 60, 90, and a deck 80. As shown in FIG. Each of these configurations will be discussed in detail.

Alternate 10 and bridge 20 are each a means of supporting the bridge. The alternation (10) is made up of a pair of mutually spaced apart portions, and the first isosceles (12) are provided on one side of each of the alternations (10). The bridge piers 10 are installed between the alternations 10 and comprise at least one or more of them.

The first diaphragm 12 is provided on one side of the upper portion of the alternation 10 and the second diaphragm 22 is provided on the upper center of the pier 20. Each of the first and second skewers 12 and 22 is a portion where the elastic plate 30 is installed. The first and second timetables may be made of either concrete or steel structures.

The elastic plate 30 is a means for absorbing and dispersing the weight of the bridge and the wind pressure applied to the bridge or the passing load of the pedestrian. The elastic plate 30 is composed of first and second elastic plates 32 and 36. The first elastic plate 32 is formed by stacking a plurality of first support plates 322, And a plurality of second support plates 362 are stacked on the second elastic plate 36 and installed on the upper surface of the second guide plate 22.

3A, each of the first and second elastic plates 32 and 36 is stacked on the first and second elastic plates 32 and 36 in such a manner that the area of the first and second elastic plates 32 and 36 increases, 1 and 2 support plates 322 and 362 are curved so as to be concave upward with respect to the central portion. This will be described later in order to appropriately absorb and disperse the external force acting on the bridge.

The steel plate strip girder 40 is composed of a pair of right and left plates having a predetermined width and a predetermined thickness and a predetermined length and is mounted on the upper surface of each of the first and second elastic plates 32 and 36, And is fixedly coupled to the other side. Both ends of the steel strip strip girder 40 fixedly coupled to the other side of each of the turns 10 may be embedded further in the ground as shown in the figure. When the steel plate strip girder 40 is mounted on the upper surface of each of the first and second elastic plates 32 and 36, the edge portions of the first and second elastic plates 32 and 36 fall downward as shown in FIG. 3B.

That is, the restoring force (dotted line) of the first and second elastic plates 32 and 36 acts upward while absorbing the self weight (solid line) of the steel strip strip girder 40, The restoring force of the first and second elastic plates 32 and 36 absorbs not only the own weight of the steel strip girder 40 but also the load of each part constituting the bridge, and all the external forces such as strong winds and pedestrian passing loads And absorbs it. The structural stability of the bridge can be greatly improved due to the restoring force of the first and second elastic plates 32 and 36.

The beam 50 is a means for installing the handrail 60 structure and the roof structure. The beam 30 is made up of a plurality of beams spaced apart from each other by a predetermined distance and positioned below the steel strip girder 30. [ The cross beam 30 is preferably made of a metal material such as a steel pipe.

The stringer 70 comprises first and second stringers 72 and 76. The first stringers 72 are composed of a plurality of first stringers 72, which connect the central portions of the respective beams 50 adjacent to each other. That is, one end portion of each first longitudinal beam 72 is fixedly coupled to one side portion of one adjacent cross beam 50, and the other end portion of each first longitudinal beam 72 is connected to the other side portion of the adjacent cross beam 50 And is fixedly coupled. The second stringers 76 are composed of left and right pairs, and both ends of the second stringers 76 connect the two side portions of the adjacent beams 50. The connection between the second stringer 76 and the beam 50 is very similar to that of the first beam 72.

The deck 80 is a top plate on which the pedestrians move, and is made up of a plurality of bars provided adjacent to the top of the steel strip strip girder 40. 4, the central part of each deck 80 is fixedly coupled to the first stringer 72 and the transverse bar 50. Each of the right and left sides of each deck 80 is connected to the iron plate strip 40 and the beam 50, And both left and right ends of each deck 80 are fixedly coupled to the second stringer 76 and the beam 50. The deck 80 may be made of wood or synthetic resin.

The railing 60 and the railing cable 90 are the means for the safety of pedestrians. The railing (60) is installed vertically on both sides of each beam (50). As shown in FIG. 1, the railway cable 90 has a plurality of vertical heights, and each of the railway cables 90 is installed along a hanging end 62 provided at one side of the railway 60 as shown in FIG.
