[0001] The present invention relates to a bridge having a rotating bridge,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bridge having a rotary bridge pier, and more particularly to a bridge having a bridge bridge that rotates according to the water flow of the river.

A bridge is a civil structure that is laid across a river, lake, strait, bay, canal, jersey, river, river, road, valley, or narrow strait of the sea. The bridges are equipped with bridges to support bridges such as decks or girders. The most common bridges are in the form of fixed bridge piers. These bridge bridges are made of concrete columns or steel columns do.

Bridges equipped with such fixed bridge piers may be installed in wide rivers, but may be installed in narrow rivers such as in the city. In particular, bridges such as the city, which are narrow and narrow, can be constructed.

It is a bridge that weaves the fir tree. Here, 섶 섶 섶 잎........................ In addition, 隆 ダ リ is also used for bridges made of tree twigs. Generally, pine trees are used to make thick pillar trees, which are laid on pine trees. Logs are laid on them, twigs of pine trees are entangled, and the soil is covered with pine trees.

These ladders are smaller in size than typical bridges and are installed in narrow rivers such as the city. But when there is a lot of rain like flood. In narrow rivers such as the city, the flow rate of rivers increases sharply and the flow rate also increases sharply compared to wide rivers. As the flow rate and the flow rate of the river increase, the resistance between the water and the bridge also increases.

As a result, due to the increased flow rate and flow rate, small bridges such as bridges are easily broken or the bridges are entirely flooded by water with increased flow rate and flow rate.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a bridge having a rotary bridge bridge that reduces the resistance between water and a bridge as the flow rate and the flow rate increase.

To achieve these and other advantages and in accordance with the purpose of the present invention, as embodied and broadly described herein, there is provided a bridge structure comprising: an upper structure of a bridge disposed in a shape of a bar, And a column member coupled to the upper structure to support the upper structure, wherein the column member comprises: a stationary column member having an upper end fixedly coupled to the upper structure and a lower end vertically penetrated and fixed in the underwater ground; And a rotating pillar member rotatable in a direction transverse to the upper structure about an upper end portion.

The rotating pillar member may be formed such that an upper end portion thereof is rotatably engaged with the upper structure and a lower end portion thereof is pressed against the surface of the underwater ground.

The rotating pillar member may be formed such that an upper end portion thereof is rotatably coupled to the upper structure and a lower end portion thereof is spaced apart from the surface of the underwater ground by a predetermined distance.

The pillar member may include a hinge coupled to the upper structure.

The rotating pillar member may include a hook portion coupled to the upper structure so as to be separated from the upper structure after rotating by a predetermined rotation angle.

The hook portion includes a hook portion rotatably coupled to the upper structure in a horizontal direction; And a hooking part fixed to the upper end of the rotary post and detachably coupled to the hook.

The upper structure includes an upper plate portion to which the column member is coupled; A plurality of support beams extending in the longitudinal direction of the upper structure and spaced apart from each other across the upper structure and disposed on the upper plate; A cover portion having a size corresponding to the upper plate portion and including a plurality of recesses formed in the gravity direction between the support beams while being supported by the support beams; And a pocket portion formed to be seated on the concave portion and extending along the longitudinal direction of the upper structure.

The pocket portion is provided on a side surface of the upper structure and extends in the longitudinal direction of the upper structure and has a housing space formed therein. An inlet formed at one side of the case to communicate the accommodating space with the outside; A projection protruding upward from the upper portion of the charging port; And a fixing pin vertically disposed while sequentially passing through the projection and the inlet.

1 is a schematic view showing a bridge 1 having a rotary bridge bridge according to an embodiment of the present invention. Referring to FIG. 1, a bridge 1 having a rotary pier is installed to cross a river and is connected to an upper structure 100 and a upper structure 100 of a bridge formed in the shape of a bar, And a column member for supporting the column member.

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

The upper plate 110 is formed in a plate shape so that a person or a vehicle can pass across the river. The upper plate 110 is supported by a column member that engages with the lower side.

The support beams 130 are made of a plurality of beams extending in the longitudinal direction of the upper structure 100. The supporting beam 130 may be an H-shaped beam having an H-shaped section, for example. When the supporting beam 130 is an H-beam, the supporting beam 130 may have a H- . Here, the lying H shape is a shape in which H is rotated clockwise or counterclockwise by 90 degrees.

Also, the support beams 130 are arranged in parallel to each other along the longitudinal direction of the upper structure 100, and spaced apart from each other in a direction crossing the upper structure 100.

The cover portion 120 may be made of a relatively well-bent metal plate such as a zinc-plated steel plate, and is formed to have a size corresponding to the top plate portion 110.

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

That is, the cover portion 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 or the like is accumulated on the cover part 120, the step 170 acts as a resistance, so that the soil 170 and the like can be firmly held.

The pocket portion 150 is disposed on the upper surface of the cover portion 120 and is formed on both side portions of the upper structure 100 along the longitudinal direction of the upper structure 100 so as to attach a bell- Respectively. As a result, you can replace the bell at any time with little cost.

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

The case 151 is provided on a side portion of the upper structure 100 and is formed to extend along the longitudinal direction of the upper structure 100 and has a receiving space capable of receiving a bell gong or the like therein. The case 151 is formed with a charging port 153 at one side of the case 151 so as to communicate the receiving space with the outside.

The case 151 is formed so as to be placed on the concave portion 121 and to be disposed on the convex portion 123 formed on the outer side of the concave portion 121 where the input port 153 is formed. The convex portion 123 serves as a latching jaw so that the case 151 is prevented from being detached from the upper structure 100. When the soil 170 is accumulated on the case 151, friction between the concave portion 121 and the case 151 increases due to the weight of the soil 170 and the like, so that the case 151 is separated from the upper structure 100 .

The protrusion 155 is formed on the upper surface of the case 151 and protrudes upward at a portion where the loading port 153 is formed. The protrusion 155 prevents the cover 170 and the soil 170 stacked on the cover 120 and the case 151 from being separated from the upper structure 100.

The fixing pin 157 serves to fix a breech block or the like received in the receiving space of the case 151 through the input port 153. The fixing pin 157 is provided so as to be vertically arranged while sequentially passing through the protruding portion 155 and the input port 153.

The pillar member is formed to support the upper structure 100 by being coupled to the upper structure 100. Specifically, the column member is coupled to the upper plate portion 110 and includes a stationary pillar member 200 and a rotating column member 300.

Hereinafter, the fixed post member 200 will be described with reference to Fig. Fig. 2 is a cross-sectional view showing the fixed post member shown in Fig. 1. Fig.

Referring to FIG. 2, the stationary pillar member 200 serves as a main pillar supporting more than half of the weight of the upper structure 100. The fixed column members 200 are vertically arranged with the upper end fixedly coupled to the upper plate 110 and the lower end penetrated and fixed to the underwater ground G. [

The fixed column member 200 includes a steel column 230 and an outer portion 210 made of a wood material to surround the outer side of the steel column 230 to enhance aesthetics.

Hereinafter, the rotating column member 300 according to one embodiment will be described with reference to FIG. FIG. 3 is a cross-sectional view of the rotating column member shown in FIG. 1. FIG.

Referring to FIG. 3, the rotating pillar member 300 may serve as an auxiliary piercing supporting half or less of the weight of the upper structure 100. At least one of the rotating pillar members 300 is vertically disposed between the fixed pillar members 200.

In order to prevent damage to the pier due to the increase in the resistance of the pier to the pier when the flow increases due to the increase of the flow rate and the flow rate due to the flood of the river, And the lower end of the pillar member 300 is detached from the underwater ground and is rotatable along the direction F in which the water flows around the upper end of the pillar member 300.

Since the rotary column member 300 is arranged in an oblique direction not perpendicular to the flow direction F of the water as well as the water immersion portion is reduced when the upper portion is rotated around the upper end portion, resistance due to friction with water is reduced do. Here, the direction (F) in which the water flows is the direction across the upper structure 100.

The rotary pillar member 300 is rotatably coupled to the upper plate portion 110 such that the upper portion thereof is rotatable along the arrow R in the direction transverse to the upper structure 100 and the lower end portion thereof presses the surface of the underwater ground G .

In other words, the rotary column member 300 is formed such that the lower end portion of the stationary post member 200 is fixed to the underwater ground, but the lower end portion is not fixed to the underwater ground, but is pressed only on the surface of the underwater ground. So that the lower part is easily separated from the underwater ground when the flow rate and the flow rate of the river increase.

Meanwhile, the rotary column member 300 may be disposed such that the lower end thereof is spaced apart from the underwater ground by a predetermined distance in the vertical direction without contacting the underwater ground. In this case, the pillar member 300 is suspended from the upper structure 200, so that the weight of the pillar member 300 is supported by the upper structure 200. In this case, the principle that the rotary column member 300 rotates in accordance with the flow of the river is as described above.

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

The hinge part 310 includes a first coupling part 311 fixedly coupled to the upper plate part 110, a second coupling part 313 fixedly coupled to the upper end of the rotary column member 300 and rotatably coupled to the first coupling part 311, And a fastening bolt 315 for fastening the first coupling portion 311 and the second coupling portion 313 to each other.

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

4, when the lower end of the rotary column member 400 is separated from the ground G, the rotary column member 400 is rotated in the direction F in which water flows in the upper end portion of the rotary column member 400 It may be formed so as to be separated from the upper structure 100 when it rotates along the arrow R and rotates by a predetermined rotation angle or more. In this case, the resistance with water can be further reduced as compared with the case where the above-described separation is not performed.

In addition, since the spacing between the fixed post members 200 is increased as the rotary post member 400 is removed, by-products, which are bulky due to floods or the like, can easily pass between the fixed post members 200. Therefore, it is safer and the lifetime of the bridge can be extended, compared with the case where a bulky by-product is caught between the column and the column and the resistance of the water by the by-product is greatly increased.

The rotary pillar member 400 according to this other example includes a hook portion 410 which is engaged with the upper plate portion 110. The hook portion 410 includes a hook portion 411 and a hook portion 413. [

The ring 411 is rotatably coupled to the upper plate 110 and is rotatably coupled to the upper plate 110 while the other end of the ring 411 is rotatably coupled to the upper end of the ring 411 (411a).

The hooking portion 413 is formed to be detachably coupled to the hook portion 411. For example, the hooking part 413 may be provided with a protruding part 155 having a through-hole formed to be engaged with the hook part 411.

The end 411a of the hook 411 is rotated so that the stream is directed downstream and the hooking part 413 is hooked on the hook 411 to join the rotary pillar member 400, And as the flow rate increases, the rotary column member 400 gradually rotates about the upper end portion.

At this time, the hooking part 413 moves toward the distal end 411a along the inner surface of the ring part 411. [ When the rotary pillar member 400 then exceeds a predetermined rotation angle, the hooking portion 413 goes beyond the distal end 411a of the hook portion 411 and eventually disengages from the hook portion 411. Therefore, the pillar member 400 is also detached from the upper structure 100. At this time, when the rotary column member 400 is about 45 degrees from the direction in which gravity acts, it can be released.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
