However, since the bridge for bicycle traffic according to the related art constitutes the bridge of the bridge by the H beam, the bridge between the bridges is shortened, the interval between the piles forming the bridge is narrowed, and the mold is constituted by a plurality of H beams There is a problem that the bridge is complicated and the appearance and the workability are deteriorated.

The present applicant has developed a bicycle traffic bridge for solving the problem of the bicycle traffic bridge according to the related art, and filed it with the Korean Intellectual Property Office and registered with the registration number No. 1164935.

In the case of constructing the bridge for bicycle traffic according to the above registered patent technique, the number of the existing piles supporting the upper structure can be reduced, and the bridge can be simplified by constituting the bridge of the bridge with one steel pipe.

However, there is a problem that the bridge structure has a limit in reducing the length of the bridge and the number of the bridge columns as a simple beam shape, and the deflection increases.

Therefore, it is necessary to develop a continuous bridge type bicycle traffic bridge which can increase the length of the bridge to reduce the number of piers and decrease the sagging.

The continuous bridge for bicycle traffic according to the present embodiment is a continuous bridge for bicycle traveling in the form of a continuous span bridge 2, comprising: a plurality of bridge columns 14 spaced apart from each other along a linear line of the bridge; A tofu point 18 fixed to the head of the bridge pillar 14; A point girder 24 coupled to an upper portion of the toe point 18 and filled with concrete 26 to a certain distance at both sides of the toe point 18 and a transverse girder 28 extending at both ends of the point girder 24, A pipe-shaped steel pipe girder (30) comprising: A plurality of lateral brackets (32) spaced from each other along the longitudinal direction of the steel pipe girder (30) and extending laterally at a side end of the steel pipe girder (30); And a bottom portion 42 formed on the transverse bracket 32 along the longitudinal direction of the bridge to provide a traveling path.

The distance between the bridge pillar and the pier is called the span or the span. In the simple bridge, the upper structures are separated from each other and the two piers adjacent to each other support both ends of the pier. , And the continuous bridge (2) is a form in which the mold is not separated but supported by three or more bridge bridges. The continuous bridge (2) is advantageous in that the number of the pier pillars (14) can be reduced because the sagging can be simplified because the sagging is not so severe as compared with the simple bridge.

2 is a moment curve showing moment generated in the continuous bridge 2 by its own weight and no moment is generated at the outermost point 4 supporting both ends of the continuous bridge 2, (-) moments occur at the points (4) between the points (4). At the point (4) where these moments occur, the consecutive bridge (2) is heard upward by the moment.

In this embodiment, as shown in Fig. 3, three bridge piers 14 support a single steel pipe girder 30, and a description will be made with reference to a two-span continuous bridge.

The continuous bridge for bicycle traffic according to the present embodiment means a small bridge having a small operating load that can be moved by a pedestrian or a bicycle. Unlike a general bridge which receives a large working load, It is necessary to construct bicycle traffic bridges quickly and economically because of simplification, concern about environmental pollution, increase in leisure activity population and so on.

The pier pillars 14 are spaced apart from each other on the ground 12 along the linear form of a bicycle continuous bridge to be constructed. The bridge pillar 14 constitutes a pier of the continuous bridge for bicycle passage and supports the steel pipe girder 30 which is the upper structure of the continuous bridge.

In this embodiment, a pillar 14 is formed by piling or piling a foundation pile 16 along a linear shape of a bridge. Since the foundation pillar 16 is provided on the ground to form the bridge pillar 14, the lower structure of the bridge can be simplified, and the construction can be performed quickly.

In the continuous bridge for bicycle passage, a plurality of steel pipe girders 30 are successively installed in a continuous bridge (2) on a plurality of installed piles (16) along a linear shape of the bridge to complete the linearization of the entire bridge.

The existing pile 16 is a pile manufactured in advance at a factory or the like and includes a PHC pile, a steel pipe pile, an H pile and the like, and is installed perpendicularly to the ground 12 by hanging or embedding.

The tofu point 18 is installed on the head of the foundation pile 16 constituting the bridge pillar 14 and joined to the steel pipe girder 30. [ When the foundation pile 16 is installed on the ground 12, the upper end of the foundation pile 16 is cut according to the height of the bridges to be constructed, the head of the foundation pile 16 is assembled, Lt; / RTI >

The tofu point 18 includes a head cap 20 that is coupled to the head of the ready-made pile 16 and a head point plate 22 that is horizontally coupled to the top of the head cap 20. A vertical stiffener is coupled between the lower end of the toe point plate 22 and the outer surface of the head cap 20 to reinforce the rigidity of the toe point 18. Both ends of the point girder 24 and the steel pipe girder 30 of the steel pipe girder 30 are joined to the tofu point 18 in the form of a continuous bridge 2.

The steel pipe girder 30 is a pipe type pipe made of steel and is joined to the top of the toe point 18 and has a point girder 24 to which concrete is charged to a certain distance on both sides from the toe point 18, And girder girder 28 extending from both ends of the point girder 24. In this embodiment, a round steel pipe having a circular section is used as the steel pipe girder 30. [

The steel pipe girder 30 is supported by a plurality of pierced pillars 14 in the form of a continuous beam. The pierced pillars 14 between the outer piercings 14 supporting both ends of the steel pipe girder 30 are supported by steel pipe girders 30 ), And the steel pipe girder 30 is heard upward due to such a moment.

The point girder 24 of the steel pipe girder 30 is joined to the toe point 18 at which the momentum is generated and is filled with concrete 26 therein. The weight of the steel pipe girder 30 is increased at the upper portion of the toe point 18 where the momentum is generated due to the filling of the concrete 26, At this time, the concrete 26 is filled up to a certain distance on both sides at the toe point 18 where the moment is generated. For example, in designing a continuous bridge for a bicycle, the distance at which the moments become zero at the point (4) where the moment is generated can be calculated, and then the concrete can be filled with the distance.

The girder 28 of the steel pipe girder 30 is not filled with the concrete 26 as a portion extending from both ends of the point girder 24 filled with the concrete 26. [

The steel pipe girder 30 can be formed by splitting the steel pipe girder 30 into the branch girder 24 and the ground girder 28 and combining the steel pipe girder 30 in the field during the construction of the bridge for convenience of construction and transportation efficiency.

When the steel pipe girder 30 is formed as one steel pipe, the concrete 26 is filled with a certain distance to the portion to be joined to the toe point 18 where the momentum is generated according to the design to form the point girder 24 can do.

On the other hand, the concrete 26 can be filled in both ends of the steel pipe girder 30 supported by the toe point 18. When both ends of the steel pipe girder 30 are fastened to the tofu point 18 by bolts or the like, a moment may be generated at both ends. Concrete 26 may also be filled at both ends of the steel pipe girder 30 to minimize the perception of both ends by this momentum.

In this embodiment, one girder in the form of a steel pipe is used as a continuous beam to support the load acting on the upper part of the bridge and to transmit it to the pier column 14. [ Accordingly, the upper structure of the continuous bridge for bicycle traveling can be simplified and the number of the pillar posts 14 can be reduced by extending the bridge span.

The steel pipe girder 30 can be joined to the tofu point 18 through the girder point 41. The steel pipe girder 30 is connected to the bridge pillar 14 by connecting the girder point 41 to the toe point 18 by coupling the girder point 41 to the toe point 18 in the steel pipe girder 30. [ Respectively.

A fastening hole may be formed in the toe point plate 22 of the toe point 18 and the girder point plate 40 of the girder point 41. The fastening hole may be formed through the fastening hole in the field by the high tension bolt, The girder point 41 can be fastened.

The girder point 41 is provided with a reinforcing plate 50 coupled to extend to both sides of the lower portion of the steel pipe girder 30 and a first engaging plate 52 coupled to the lower end of the reinforcing plate 50 in the lateral direction (54); A girder point plate 40 opposed to the tofu point plate 22 and a support plate 56 vertically coupled to the girder point plate 40 and a support plate 56 opposite the first engagement plate 52, And a second coupling plate 58 which is laterally coupled to the first coupling plate 60. [

When the linear shape of the bridge forms a curve, a plurality of steel pipe girders 30 are continuously installed to form a curved section. The steel pipe girders 30 are installed while being gradually twisted so as to form a curve do. At this time, since the toe point 18 and the girder point 41 are twisted to each other, the aesthetic appearance of the bridge can be damaged, and the joints between the toe point 18 and the girder point 41 are displaced, It can be difficult. Accordingly, in the present embodiment, the girder point 41 is divided into the girder connecting portion 54 and the point connecting portion 60, and the girder connecting portion The steel pipe girder 30 can be installed on the bridge pillar 14 without hindering the beauty of the bridge by lifting the steel pipe girder 30 to which the bridge connecting portion 60 and the girder connecting portion 54 are coupled, Respectively.

The girder coupling portion 54 is coupled to the steel pipe girder 30 and includes a reinforcing plate 50 coupled to extend to both sides of the lower portion of the steel pipe girder 30, And a first engaging plate (52). The point joining portion 60 is coupled to the toe point 18 and includes a girder point plate 40 opposed to the toe point plate 22 and a support plate 56 And a second coupling plate 58 opposed to the first coupling plate 52 and laterally coupled to the upper end of the support plate 56. The first coupling plate 52 and the second coupling plate 58 have fastening holes corresponding to each other and are fastened to each other by a high tension bolt or the like when the steel pipe girder 30 is installed. At this time, the fastening holes of the first coupling plate 52 and the second coupling plate 58 may be formed in a linear slot shape so that the slots intersect with each other.

The girder point plate 40 of the girder point 41 and the girder point plate 40 of the toe point 18 at the time of installation of the steel pipe girder 30 are spaced from each other in the first slot 64 and the second slot 66 and through a linear first slot 64 passing through the toe point plate 22 and a linearly extending through the girder point plate 40, as shown in Figures 6 and 7, The second slots 66 may be formed to intersect with each other. Accordingly, even if the steel pipe girder 30 is turned to form a curved section, the first slot 64 and the second slot 66 can communicate with each other while crossing each other.

A lateral bracket 32 for supporting the bottom portion 42 is coupled to the steel pipe girder 30. The joint portion of the lateral bracket 32 is locally stressed by the lateral bracket 32, can do. 8, a girder reinforcing plate 62 crossing the cross section of the steel pipe girder 30 is coupled to the inside of the steel pipe girder 30 in correspondence to the engagement position of the lateral bracket 32 .

The lateral brackets 32 are spaced from each other along the longitudinal direction of the steel pipe girder 30 and extend laterally at the side ends of the steel pipe girder 30. [ The transverse brackets 32 are joined in the form of a cantilever in the transverse direction with respect to the throttle at the side of the steel tube girder 30. [ The lateral bracket 32 can be fixed to the side of the steel pipe girder 30 by welding or high tension bolts.

The lateral bracket 32 according to this embodiment includes a pair of webs 34 that are coupled to the outer circumferential surface of the steel pipe girder 30 so as to extend in the lateral direction at both side ends of the steel pipe girder 30, A pair of lower flanges 38 extending longitudinally at opposite ends of each of the pair of webs 34 and coupled longitudinally to each of the lower ends of the pair of webs 34, And an upper flange 36 joined longitudinally to the upper end of the pair of webs 34 so as to extend from one end to the other end of the web.

One upper flange 36 is longitudinally coupled to the top of a pair of webs 34 from the other end of one of the pair of webs 34 to the other.

Since the lateral bracket 32 is coupled to the side end of the steel pipe girder 30 in the form of a cantilever, the greatest moment is generated at the upper end of the engaging portion with the steel pipe girder 30. [ In order to effectively resist such a moment, one upper flange 36 is coupled to the upper end of a pair of webs 34 from the other end of one of the pair of webs 34 to the other end thereof in the longitudinal direction .

A railing 48 for preventing the fall of a pedestrian or a bicycle may be coupled to the upper portion of the outer side of the lateral bracket 32.

The transverse bracket 32 is not limited to an I-shaped steel, but various types of structural steel such as a box-like steel may be used.

On the other hand, the transverse brackets 32 can be divided into several pieces for the convenience of construction and transportation efficiency, and can be coupled again when the bridge is constructed.

The bottom portion 42 is formed along the longitudinal direction of the bridge on the transverse bracket 32 to provide a path for a pedestrian or a bicycle.

The bottom portion 42 according to the present embodiment includes a deck plate 44 provided so as to be supported at both ends thereof on the upper portion of the transverse bracket 32 in the throttling direction and a deck plate 44 ).

In the case of the structural plate in which the deck plate 44 is alternately formed with the rib-shaped portion and the floor portion, the deck plate 44 is arranged such that the rib-shaped portion is disposed laterally with respect to the upper flange 36. When the deck plate 44 is installed, the paving concrete 26 is poured and cured to form the concrete pavement 46.
