Description

TECHNICAL FIELD [0001] The present invention relates to a method of constructing a bridging bridge using a hinge device having a height adjustment function and a fall prevention function,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a method of raymen bridge construction using a hinge device having a height adjustment function and a fall prevention function. More specifically, it is easy to install and manufacture in the ramen bridge construction, but it has the function of permitting the sagging of the mounted girder and preventing the fall, thus making it more economical and efficient. The ramen bridge construction using the hinge device ≪ / RTI >

Raman Bridge, a bridge construction method that excludes conventional bridge support devices and expansion joints, has been introduced.

For example, a ramen bridge construction method capable of effectively controlling the bending moment generated in the right and left sides of a ramen bridge can be more effectively introduced. (Patent 10-1135634: And a ramen bridging method using the right-handed bridging method)

Specifically, as shown in FIG. 1A,

The saddle 20 is hinged to the girder 10 by a fixed load due to its own weight by the saddle 20 being hinged at the point where the girder 10 and the bridge pier Causing deflection to occur,

A bottom plate is formed on the upper portion of the girder and a saddle 20 is embedded in a fulcrum and a fulcrum in an alternating upper space. By alternating and strengthening, the load caused by the weight of the girder and the bottom plate is to be borne by the girded girder.

This makes it possible to stably support the girder 10 in the bridge substructure 30 such that the saddle 20 acts as a hinge to allow both ends of the girder to rotate, Is not transmitted to the bridge substructure (30)

It is possible to use the slimmer girder because the weight of the girder in the ramen bridge has a function to greatly reduce the flexural moment generated in the bridge substructure and the strong right corner.

The saddle 20 shown in FIG. 1A includes a lower saddle 22 provided on a bridge substructure and an upper saddle 21 provided on the bottom of both ends of the girder, The upper saddle 21 is formed as a convex portion formed on the lower surface of the upper saddle 21 and coupled to the lower end of the girder 10 by the anchor bolts. Is formed by a bottom plate coupled to the upper surface of the bridge substructure 30 by anchor bolts and a concave portion formed on the upper surface as a block member protruding upward on the upper surface of the lower plate so that the upper saddle It can be seen that the convex portions come into contact with each other to be hinged.

As a result, when the hinge device is manufactured in the same shape as the bridge support, there is a problem that the cost of manufacturing and installing the bird is increased.

Even in the case of a composite girder for other bridges (passenger's patent No. 10-2010-0018958: a method of producing a composite girder for a bridge using a manufacturing facility of a hinge structure), the hinge device 40 used in the manufacturing process 1b.

That is, the hinge device 40 includes a first tiltable member 41 positioned below the horizontal support and having a first curved surface portion; And a second tiltable member (42) which is located on the upper portion of the vertical support and has a second curved surface portion that makes contact with the first curved surface portion of the first tiltable member, It is understood that the first and second curved portions are allowed to rotate relative to each other by the contact of the curved portion 43 of the girder 10, thereby accommodating the rotational displacement resulting from the deflection of the girder 10.

However, such conventional hinge apparatuses are also manufactured in the same shape as the birds of FIG. 1A, so that it is inevitable that the economical efficiency in making and constructing bridges is inferior.

Further, FIG. 1C shows a conventional anti-fall device (a device for preventing the PSC beam from falling off the plate) used for mounting the conventional girder 10 for bridges.

That is, when the PSC beam is mounted on the upper part of the coping of the pier, the reinforcing anchor 1 is embedded in advance on the coping 9, and when the PSC beam 2 is stationary therebetween, The turnbuckle 3 and the PC stranded wire 4 are connected and fixed between the shear reinforcement 5 and the anchor 1,

It can also be seen that the anti-reverse bracing reinforcement 7 is installed at a predetermined interval in the front-end reinforcing bars 5 of the PSC beam 2, and the work is proceeding to prevent the falling.

In other words, although it is known that various reinforcing bars are used, many of them are installed between the bridge piers, the girders, the girders and the girders. Therefore, there is a limit in that the applicability and operability are inevitably deteriorated when applied to the ramparts.

Accordingly, in the ramen bridge construction, it is possible to set the height from the upper surface of the alternating frame when the girder is mounted, and to prevent the embedding of the mounted girder is very simple, and it can act as a hinge device, And to provide a method of providing a ramen bridge construction method using a hinge device having a height adjustment function and a fall prevention function as much as possible.

Furthermore, since the hinge device is very simple to manufacture but permits the sagging of the girder without any special work, the influence of the bending moment due to the weight of the girder is not transmitted to the alternating side. Thus, the hinge device capable of performing economical rammen bridge construction And to provide a method of providing a brassiamong bridge construction method using the apparatus.

[Hinge device 100 with height adjustment and anti-fall function]

FIGS. 2A, 2B, and 2C are a perspective view, a perspective view, and an installation front view, respectively, of a hinge apparatus 100 having a height adjusting function and a fall preventing function according to the present invention.

The hinge device 100 is allowed to sag while supporting the bottom end of the girder 200. The hinge device 100 is installed to be fixed to the upper surface of the alternate 300.

As shown in FIG. 2A, the hinge device 100 uses a steel material 110 having a H-shaped cross section so that the steel material 110 can be easily manufactured, and the flange 111 and the abdomen 112 are provided. have.

Accordingly, the abdomen 112 is disposed on the upper surface of the alternate 300 in such a manner that the abdomen 112 is disposed laterally,

The lower surface of the bottom flange of the end portion of the girder 200 contacts the upper surface of the abdomen portion 112 to allow the downward deflection of the girder 200 between the hinge devices according to the height of the hinge device 100, So that the bending moments due to the self-weight of the wiper 300 are not transmitted to the alternate 300.

The flanges 111 of the H-section steel member 110 are formed in the form of a horizontal plate on both the flange and the bottom of the abdomen of the H-section steel member 110 so that the base plate 113 is fixed in advance on the upper surface of the alternate 300 And the through hole 114 is formed in the base plate 113.

That is, the base plate 113 is formed as a horizontal plate formed on the bottom of both flanges 111, and is formed as a single horizontal plate having a transverse width equal to the transverse width between both flanges 111, 140 will penetrate, the size will not be a problem.

The lower end of the fixed anchor 140 is fastened to the insert 310 and the lower end of the fixed anchor 140 is fastened to the upper surface of the insert 310, So as to protrude upward.

The upper end of the fixed anchor 140 is inserted into the through hole 114 formed in the base plate 113 of the steel member 110 having the H cross section and the height adjusting nut 130 is used as shown in FIGS. The height of the hinge device 100 can be adjusted by adjusting the setting position of the fixing anchor 140 of the base plate 113. [

A plurality of height adjusting nuts 130 are provided on the upper and lower surfaces of the base plate 113 to adjust the height of the height adjusting nut 130.

However, when installing the inserts 310 and the anchors 140, it is difficult to accurately set the originally planned positions due to a construction error. Typically, such a construction error is caused by forming the through holes 114 in an elliptical shape or a slot shape It is common to absorb.

However, the formation of the through-hole 114 in the base plate 113 may cause a structural problem due to a reduction in the cross-section, so that the intermediate height adjuster 120 is additionally installed in the present invention.

That is, when the through holes 114 are formed to be large in consideration of the case where the through holes 114 and the fixed anchors 140 do not match with each other, the height adjusting nuts 130 are also formed in a size of the through holes 114 Therefore, the through hole 114 can be easily formed to a size large enough to allow the fixing anchor 140 to pass therethrough,

A middle height adjuster 120 in the form of a horseshoe is provided between the height adjusting nut 130 and the upper surface of the base plate 113 and between the bottom surface of the base plate and the height adjusting nut 130 as shown in FIGS. 2B and 2C, The adjusting member 120 effectively transmits the fastening force of the height adjusting nut 130 to the base plate 113 so that the height adjusting nut 130 can be set regardless of the size of the through hole 114.

Since the thickness of the height adjusting nut 130 can be adjusted, there is no problem in adjusting the height of the hinge device 100,

When the girder 200 is mounted on the upper surface of the abdomen 112, the load due to the conduction or the like is transmitted to the fixed anchor, and the intermediate height adjuster 120 also acts as a reinforcing member.

The middle height adjustment member 120 is formed in a horseshoe shape and has a side insertion hole 121 extending from the outer circumferential surface to the center, which is advantageous to be inserted laterally into the fixed anchor.

[Operation of hinge device of the present invention]

2 (d), it can be seen that the girder 200 is mounted on the upper surface of the hinge device 100. FIG.

In other words, since the extension length of the abdomen 112 is formed to be larger than the width of the lower flange of the girder 200, allowing conduction due to a mounting load or the like in permitting a point by mounting, It is necessary to install additional anchors on the alternating upper surface, and the alternate upper surface space may be narrowed, which may interfere with the operation.

2A and 2C, a connecting hole 116 is formed in the lower end of the abdomen 112 of the hinge device 100 and a connecting hole 115 is formed in the lower flange, And a slant coupling member 150 such as a wire or the like is additionally provided between the upper and lower connection ports 115 and 116 so that the girder 200 and the hinge device 100 are restrained to prevent conduction.

Both end portions of the inclined connecting member 150 are provided with hooks, and a turnbuckle is provided in the middle of the inclined connecting member 150, thereby facilitating the installation and facilitating adjustment of the tension and length.

When the connectors 115 and 116 are used as described above, it is advantageous that the filling is not disturbed by the connector and the disassembly is facilitated when the right and left concrete are installed.

2A, the lower flange 230 is brought into abutment with the upper surface of the abdomen 112 of the hinge device 100 extending in the transverse direction, Since the girder 200 is allowed to be deflected by its own weight on the upper surface, it is possible to design the optimal section of the alternation 300 by the hinge function, thereby minimizing the space for alternate construction, 300) is installed on the ground using a file, the alternation construction can be minimized.

[Method of raymen bridge construction using hinge device with height adjustment and anti-fall function]

FIGS. 3A, 3B, and 3C show a flowchart of a method of applying a brassiam bridging method using a hinge device having a height adjustment function and a conduction prevention function.

Next, the above-mentioned middle height adjuster 120 is inserted into the upper and lower surfaces of the base plate 113 from the side.

Next, the height adjusting nut 130 is further fastened to the head portion of the fixing anchor protruding upward through the through hole 114, and the installation height of the hinge device 100 is adjusted by rotating the height adjusting nuts 130 So that adjustment can be performed.

The lower surface of the lower flange 230 of the girder 200 is supported on the upper surface of the abdomen of the hinge device 100 to allow the girder to sag.

When the height adjustment of the hinge device 100 is completed, an inclined connecting member 150 is connected between the connecting ports 115 and 116 to restrain the girder 200 to the hinge device 100, thereby preventing the hinge device 100 from being turned off.

Accordingly, the inclined coupling member 150 is located inside the upper space of the hinge device 100, so that the space occupied by the alternate upper surface can be minimized.

At this time, the hinge device 100 and the girder 200 are formed on the alternate upper surface in a plurality of transverse directions.
