The present invention relates to a bridge having a rotary bridge, and more particularly to a bridge having a bridge that rotates according to the flow of water in the river.

Bridges are civil structures that span rivers, lakes, straits, bays, canals, basins, rivers, streams, roads, valleys, or narrow straits of the sea. Bridges are equipped with bridges to support bridge superstructures, such as slabs or girders. The most common bridges are in the form of fixed bridges, which can be fixed in the bottom of the water and made of concrete columns or steel columns. do.

Bridges equipped with such fixed piers may be installed in wide rivers, but may be installed in narrow rivers such as streams. In particular, bridges called `` leg bridges '' are built in rivers that are narrow and narrow like ships.

A leg is a bridge made of weave of firewood. Here, the gingko tree is a term that refers to the gingko tree of leaf tree, green tree, and water. In addition, tusks may also mean crosslinking produced by using twigs of trees. Usually, pine trees are used to make thick pillars, which are then erected in streams. Logs are placed on top of them, the twigs of pines are entangled and the soil is covered.

These bridges are smaller than ordinary bridges and are installed in narrow rivers such as downtown. But when there's a lot of rain, like a flood. Narrow streams such as streams have a rapid increase in the flow rate of the stream compared to wide streams, and the flow velocity also increases rapidly. Increasing the flow rate and flow rate of the stream also increases the resistance of water and bridges.

As a result, small bridges such as tufts are easily damaged due to the increased flow rate and flow rate, or the entire bridge is floated by water with increased flow rate and flow rate.

Referring to FIG. 1, a bridge 1 having a rotatable bridge is disposed to cross a stream and is coupled to the upper structure 100 and the upper structure 100 of the bridge formed in the shape of a bar, and the upper structure 100. It includes a pillar member for supporting).

The upper structure 100 includes a top plate 110, a plurality of support beams 130, a cover 120, and a pocket 150.

The upper plate portion 110 is formed in a plate shape so that people or vehicles can pass across the river. The upper plate portion 110 is supported by the pillar member coupled to the lower side.

The support beam 130 (beam, 130) is composed of a plurality of beams extending in the longitudinal direction of the upper structure (100). The support beam 130 may be, for example, an H-beam having an H-shaped cross section, and when the support beam 130 is an H-beam, the support beam 130 may have an H-shaped cross section. Is placed. Here, the H shape lying down is a shape in which H is rotated by 90 degrees clockwise or counterclockwise.

In addition, the support beams 130 are arranged side by side along the longitudinal direction of the upper structure 100, are spaced apart from each other in a direction crossing the upper structure (100).

The cover part 120 may be made of a metal plate that is relatively well bent, such as an iron plate plated with zinc, and is formed in a size corresponding to the upper plate part 110.

The cover part 120 is supported by the support beam 130, and a part located between the parts supported by the support beam 130, that is, a part not supported by the support beam 130, descends in the direction of gravity. A plurality of concave portions 121 formed to sit and a portion supported by the support beam 130 include a plurality of convex portions 123 protruding in a direction opposite to the gravity direction.

That is, the cover 120 is provided with a plurality of repeated stepped portions formed by the concave portion 121 and the convex portion 123. Accordingly, the strength of the cover part 120 increases, and when the soil 170 is stacked on the cover part 120, the step 170 may be firmly held as the step portion acts as a resistance.

The pocket part 150 is disposed on the upper surface of the cover part 120 and along the longitudinal direction of the upper structure 100 on both side portions of the upper structure 100 to attach a brush or the like to both side surfaces of the upper structure 100. Is formed extending. As a result, you can always replace the brush for a fraction of the cost.

The pocket part 150 includes a case 151, a protrusion 155, and a fixing pin 157.

The case 151 is provided on the side portion of the upper structure 100, and is formed in the accommodation space for accommodating a pine branch, etc. while being formed extending in the longitudinal direction of the upper structure 100. The case 151 has an inlet 153 formed at one side of the case 151 to communicate the receiving space with the outside.

On the other hand, the case 151 is seated in the recess 121, the portion formed with the inlet 153 is formed so that the convex portion 123 formed on the outer side than the recess 121. As the convex portion 123 serves as a locking jaw, the case 151 is prevented from being separated from the upper structure 100. In addition, when the soil 170 is stacked on the case 151, the friction between the recess 121 and the case 151 increases due to the weight of the soil 170, so that the case 151 is separated from the upper structure 100. Is prevented.

The protruding portion 155 is formed on the upper surface of the case 151, but protrudes upward in a portion where the inlet 153 is formed. The protrusion 155 prevents the soil 170 accumulated on the cover 120 and the case 151 from being separated from the upper structure 100.

The fixing pin 157 serves to fix the pine branches received in the accommodation space of the case 151 through the inlet 153. The fixing pin 157 is provided to vertically pass through the protrusion 155 and the inlet 153 sequentially.

The pillar member is coupled to the upper structure 100 and is formed to support the upper structure 100. In detail, the pillar member is coupled to the upper plate 110 and includes a fixed pillar member 200 and a rotating pillar member 300.

Hereinafter, the fixed pillar member 200 will be described with reference to FIG. 2. FIG. 2 is a cross-sectional view illustrating the fixed pillar member illustrated in FIG. 1.

Referring to FIG. 2, the fixed pillar member 200 serves as a main pier supporting the weight of the upper structure 100. The stationary pillar member 200 is provided with a plurality of spaced apart from each other, the upper end is fixedly coupled to the upper plate portion 110 and the lower end is arranged vertically while being fixed intrusive to the underwater ground (G).

The fixed pillar member 200 includes an outer edge portion 210 made of a wood material surrounding the outside of the steel pillar 230 and the steel pillar 230 to increase aesthetics.

Hereinafter, the rotating pillar member 300 according to an embodiment will be described with reference to FIG. 3. 3 is a cross-sectional view showing the rotating pillar member shown in FIG.

Referring to FIG. 3, the rotating pillar member 300 may serve as an auxiliary piers that do not support the weight of the upper structure 100. At least one rotary pillar member 300 is vertically disposed between the fixed pillar members 200.

The rotary column member 300 is to prevent the breakage of the bridge pier due to the increase in the flow rate and flow rate due to the flow of the river, such as when the river is applied to the pier increases the resistance between the water and the pier The lower end of the rotating pillar member 300 is formed to be rotatable along the direction (F) in which water flows around the upper end of the rotating pillar member 300 after being separated from the underwater ground.

Rotating pillar member 300 is rotated about the upper end portion is not only reduced in water submerged, but also disposed in an oblique direction rather than perpendicular to the water flow direction (F), so the resistance due to friction with water is reduced do. Here, the direction in which the water flows (F) is a direction crossing the upper structure (100).

The rotating pillar member 300 is rotatably coupled to the upper plate 110 so that the upper end is rotatable along the arrow R in the direction crossing the upper structure 100, and the lower end presses the surface of the underwater ground G. Is formed.

That is, the rotary pillar member 300 is formed such that the lower end portion of the stationary pillar member 200 is not penetrated and fixed to the underwater ground and pressurizes only the surface of the underwater ground without being penetrated and fixed to the underwater ground. This is to allow the lower part to be easily separated from the underwater ground when the flow velocity and flow rate of the river increase.

On the other hand, the rotary column member 300 may be disposed such that the lower end portion is spaced vertically upwards from the underwater ground by a predetermined distance without contacting the underwater ground. In this case, the rotating pillar member 300 is suspended by the upper structure 200, and thus the weight of the rotating pillar member 300 is supported by the upper structure 200. In this case, the principle of rotating the column pillar 300 in accordance with the flow of the river is as described above.

The rotary pillar member) may include, for example, a hinge portion 310 such that the upper end portion is rotatably coupled to the upper plate portion 110. At this time, the rotating pillar member 300 is not separated from the upper structure (100).

Hinge 310 is a first coupling part 311 fixedly coupled to the upper plate portion 110, a second coupling fixedly coupled to the upper end of the rotating pillar member 300 and rotatably coupled to the first coupling portion 311 And a fastening bolt 315 for rotatably fastening the part 313 and the first coupling part 311 and the second coupling part 313 to each other.

Hereinafter, a rotating pillar member 400 according to another embodiment will be described with reference to FIG. 4. 4 is a cross-sectional view showing another example of the rotating pillar member shown in FIG. 1.

Referring to FIG. 4, the rotary column member 400 has a lower end portion of the rotary column member 400 separated from the underwater ground G, and then, in the direction F of flowing water about the upper end portion of the rotary column member 400. While rotating along the arrow (R) may be formed to be separated from the upper structure 100 when rotated by a predetermined rotation angle or more. In this case, the resistance with water can be further reduced than in the case of not being separated.

In addition, since the interval between the fixed pillar member 200 is widened as the rotary pillar member 400 is separated, a large by-product can easily pass between the fixed pillar members 200 by flooding or the like. Therefore, the narrower and larger by-products are sandwiched between the columns and the pillars, and thus the safety of the bridge can be extended and the life of the bridge can be extended.

The rotary pillar member 400 according to another example includes a hook portion 410 coupled to the upper plate portion 110. The hook portion 410 includes a ring portion 411 and the ring hook portion 413.

The ring portion 411 is rotatably coupled to the upper plate portion 110 in a direction crossing the upper structure and is formed in a ring shape with one side open. Specifically, one end is rotatably coupled to the upper plate portion 110 and the other end forms the end 411a of the ring portion 411.

Ring hook portion 413 is formed to be detachably coupled to the ring portion 411. For example, the hook hanger 413 may be provided as a protrusion 155 in which a through groove is formed to be hooked to the hook 411.

Accordingly, if the end 411a of the ring portion 411 is rotated so that the stream is directed downstream, the hook hanger 413 is hooked on the ring portion 411 to couple the rotary column member 400 to the flow rate of the stream. As the overflow increases, the rotary pillar member 400 gradually rotates about the upper end.

At this time, the hook hanger 413 moves toward the end 411a along the inner side of the ring 411. Thereafter, when the rotating pillar member 400 exceeds a predetermined rotation angle, the hook hanger 413 extends beyond the end 411a of the ring 411 and eventually separates from the ring 411. Therefore, the rotating pillar member 400 is also separated from the upper structure 100. At this time, the rotation pillar member 400 can be separated when the direction of gravity is approximately 45 degrees.

As described above, although the present invention has been described by way of limited embodiments and drawings, the present invention is not limited thereto, and the technical idea of the present invention and the following by those skilled in the art to which the present invention pertains. Of course, various modifications and variations are possible within the scope of equivalents of the claims to be described.
