Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

7, the socket member 200 according to the present invention is configured such that the steel girder 200 is inserted to allow the expansion and contraction behavior of the steel girder 200 installed on the upper portion of the alternation 10 or the bridge 40 (190), and both side portions and top / bottom portions of the insertion portion (190) are closed.

The steel composite bridges using the upper socket member (200) are alternately (10); A socket member (100) installed on an upper portion of the shift (10); A steel girder 200 into which an end is inserted into the socket member 100; A bottom plate concrete 20 integrally formed on the upper portion of the steel girder 200; A right angle concrete 30 formed to surround the upper portion of the shift 10 and the socket member 100; And a spacing member 300 coupled to an end of the bottom plate concrete 20 and installed on the upper portion of the steel girder 200 so that the left and right concrete 30 and the bottom plate concrete 20 are separated from each other. do.

In this case, the socket member 100 installed in the shift 100 enables the expansion and contraction behavior of the steel composite girder bridge.

That is, since the socket member 200 is installed in consideration of the maximum elongation amount and the maximum shrinkage amount of the steel girder 200, the steel girder 200 integrated with the bottom plate concrete 20 is inserted into the socket member 200, It can freely expand and contract due to deformation caused by drying shrinkage and creep.

In addition, since there is no expansion joint device (A) and a tilting device (B) as in the case of a conventional bridge, it is easy to maintain and expand and contract the upper structure (girder + bottom plate concrete) It can have a long span length.

It is preferable that the bottom plate concrete 20 and the right corner concrete 30 are simultaneously poured.

The bottom plate concrete and the right corner concrete are separated from each other due to the spacing member 300 provided on the upper portion of the steel girder 200 and the space where the upper flange of the spacer member 300 is separated from the bottom plate concrete and the right- It is possible to prevent the running vehicle from jolting. (See Fig. 9)

It is preferable that the socket member provided at the alternating portions at both ends of the bridge has a structure in which the rear portion is closed.

In this case, the socket member is formed with an inserting portion into which a steel girder is inserted in the front portion, and a rear portion, both side portions, and upper and lower portions are closed so as to prevent the concrete from penetrating into the socket when the right side portion is poured.

A socket member 100 installed on the bridge pier 40 so as to face mutually opposite directions; A plurality of steel girders (200) into which the ends are inserted into the insertion portions on both sides of the socket member (100); A bottom plate concrete 20 integrally formed on the upper portion of the steel girder 200; A pierced concrete 50 formed to surround the top of the pier 40 and the socket member 100; It is preferable that a spacing member 300 which is coupled to an end of the bottom plate concrete 20 and installed on the upper portion of the steel girder 200 is installed so that the bridge concrete 50 and the bottom plate concrete 20 are separated from each other Do.

Conventional continuous concrete rammen bridge can be constructed up to 75m with 3 spans.

Of course, it is possible to apply continuous concrete rammen bridge of 75 m or more, but there is a problem that applicability is lowered to bridge of 75 m or more due to the alternation (or pier) and the structure of the bottom plate concrete.

However, in the continuous bridge using the socket member 100 of the present invention, since the steel girder 200 and the bottom plate concrete 20 can perform the stretching and shrinking behavior at the pivot 10 and the pier 40 where the socket member 100 is installed, Therefore, it can be applied to continuous bridges over 100m.

In addition, since there is no separate expansion joint device A and the coordinate device B, maintenance is easy.

Specifically, the socket member includes a lower plate 120 coupled to the upper portion of the shift 10, and a pair of side closure portions 110 (not shown) coupled to the upper surface of the lower plate 120, ); And a finishing unit 160 formed on the outer surface.

In this case, since the socket member is composed of the lower plate portion 120, the side closing portion 110, and the finishing portion 160, the insertion portion 190 is formed inside the socket member.

The installation procedure of the socket member and the steel girder is such that the lower plate portion 120 is installed first and then the steel girder 200 is mounted and then the side closing portion 110 and the finishing portion 160 are joined.

Therefore, the steel girder 200 and the socket member 100 do not require additional equipment or additional steps in the process, which is superior in workability to the existing method.

In addition, since the steel girder 200 is enclosed by the combination of the side closing portion 110 and the finishing portion 160 after the steel girder is mounted, even if there is no separate device for preventing the falling of the steel girder, And a stable state is maintained.

It is preferable that a sliding pad 500 is installed on the upper surface of the lower plate 120 of the socket member in which the steel girder is inserted to prevent friction during the expansion and contraction of the steel girder 200.

In this case, when the lower flange of the steel girder exerts the expansion and contraction on the upper surface of the lower plate 120 of the socket member 100, the sliding pad 500 reduces frictional resistance and prevents damage to the member due to noise and friction.

It is preferable that the closing part studs 130 are formed on the outer surface of the socket member having the pair of side closing parts 110.

In this case, the joining portion stud 130 of the socket member 100 increases the coupling force between the right-angled portion concrete 30 and the socket member, and the crack resistance is improved.

It is preferable that the lower plate 120 of the socket member 100 is formed with an anchor holes 170 through which the fixing anchor 600 protruded upward is inserted.

In this case, since the fixing anchor 600 inserted and fixed on the upper surface of the shift 10 can be fixed through the lower plate anchor hole 170, the lower plate 120 can be installed quickly and stably.

In addition, the work error of the lower plate portion, which may occur in the alternate portion, can be corrected by using the fixing anchor 600 and the washer.

The washer may be inserted into a fixing anchor between the lower portion of the lower plate portion of the socket member and the alternating upper portion.

When the steel girder 200 to be inserted into the socket member of the present invention is an I-shaped section, the upper portion of the pair of side closing portions 110 is provided with a steel girder (not shown) so that the insertion portion 190 corresponds to the steel girder 200 The lower extension part 112 is formed at the lower end of the pair of side closing parts 110 to receive the lower flange of the steel girder 200 And the lower extension portion 112 is formed with a lower extension portion 180 such that the fixing anchor 600 coupled to the anchor hole 170 is commonly connected.

That is, by using a socket member that conforms to the shape of the steel material girder to be used, it is possible to effectively prevent the steel material girder from being conducted.

It is also possible to fasten the steel girder and the socket member quickly by joining the fixing anchor 600 to the lower extension portion 180 formed in the lower plate anchor hole 170 and the lower extension portion 112. 10)

It is preferable that the spacing member 300 provided on the upper portion of the steel girder 200 is installed in the lateral direction so as to be adjacent to the socket member 100.

Since the spacing member 300 is disposed between the right and left bottom plates, it is possible to prevent the concrete 30 from being coupled with the bottom plate concrete when the concrete is poured, So that a stable expansion and contraction structure of the upper structure can be attained (Figure 6). [

In addition, since the spacing members are coupled to the upper part of the steel girder by bolting or welding, there is an advantage that the construction speed is fast.

A bridge according to the present invention comprises: an alternating (10); A plurality of socket members (100) provided on an upper portion of the shift (10); A bottom plate concrete (20) including a plurality of steel girders (200) into which end portions are respectively inserted into a plurality of socket members (200), and which are commonly connected to upper portions of a plurality of steel girders (200); It is preferable to include a right-angle concrete 30 formed to surround the upper portion of the alternation 10 and the plurality of socket members 100.

Existing girder bridges should be installed with a number of gussets on the alternating girders, and the steel girders and the gussets should be connected through the first available girders when the girders are mounted.

Thereafter, it is troublesome to weld the turret device and the girder through this welding after the installation of the bottom plate and the piling.

Further, each of the plurality of girders is required to be provided with an anti-reflection device so as to maintain maintenance until the bottom plate is poured.

However, the steel composite bridge using the plurality of socket members 100 can easily install the plurality of socket members 100 and the steel girder 200 when the plurality of steel girders 200 are installed, thereby shortening the construction period .

When the connection between the girder and the socket member is completed, the construction is fast and stable because there is no separate girder preventing device or additional welding process,

In addition, since the plurality of steel girders 200 and the spacing member 300 are provided in a lattice structure, a stable structure can be maintained even before curing of the bottom plate concrete and the right corner concrete.

The separating member 300 preferably has a depression 310 into which the end of the bottom plate concrete 20 is inserted.

The depressions 310 enable stable coupling with the bottom plate concrete while protecting the ends of the bottom plate concrete (Figure 8).

In addition, it is preferable that a spacing member stud 340 is formed in the depression 310 to enhance the coupling between the bottom plate concrete 20 and the spacing member 300.

The combination of the bottom plate concrete 20, the steel girder 200, and the spacing member 300 can be further strengthened.

In this case, it is possible to reduce the amount of steel by selecting a reasonable cross section according to the bridge length (bridge length) and bridge width (bridge width of bridge), and it is possible to design economical steel composite bridge by controlling the number of steel girders.

In the above case, the socket member 100 and the I-shaped steel girder 200 are installed in the alternating system 10. The lower plate hole 170, the lower extension hole 180, and the lower flange slot of the I- Since the fixing anchor 600 is fixed and fixed to the bottom plate 210 at the same time, the construction period can be shortened and the girder can be prevented from being conducted.

The method of constructing a bridge according to the present invention is performed by the following process.

First, the alternating section 10 is installed, and the lower plate section 120 of the socket member 100 is installed on the upper surface of the alternating section 10.

In this case, since the lower plate portion of the socket member is inserted into the fixing anchor provided in the alternating structure, the construction time is short and installation is easy.

The steel girder 200 is mounted on the upper surface of the lower plate 120 and the pair of closing portions 110 and the closing portion 160 are coupled to the lower plate 120 of the socket member 100.

In this case, the steel girder is stably held by the socket member even if there is no separate anti-scattering device.

When the construction of the steel girder and the socket member is completed, the spacing member 300 is installed on the upper part of the steel girder 200 in the transverse direction, and the mold is poured to the right side concrete 30 and the bottom plate concrete 20 Install it.

In this case, since the steel girder and the spacing member are installed in a lattice structure, the steel girder remains stable until the formwork installation and the concrete curing process.

After the formwork is installed, concrete is laid and cured.

The continuous casting method according to the present invention is carried out by the following process.

The pier 40 is installed and the lower plate 120 of the socket member 100 is installed on the upper surface of the pier 40.

Thereafter, the steel girder 200 is mounted on the upper surface of the lower plate portion 120 and the pair of closing portions 110 are coupled to the lower plate portion 120 of the socket member 100.

When the construction of the steel girder 200 and the socket member 100 is finished, the spacing member 300 is installed laterally on the upper part of the steel girder 200 and the pierced concrete 50 and the bottom plate concrete 20 are installed, The mold is installed for the installation.

After the formwork is installed, concrete is laid and cured.

In this case, a continuous bridge of 100 m or more can be constructed without the expansion joint device (A) and the coordinate device (B).

This is because the steel girder 200 and the bottom plate concrete 20 can be stretched and shrunk by the socket member 100 installed at the bridge portion of the continuous bridge.

Therefore, it is possible to replace the existing continuous concrete ramen bridge installed in the middle / small river and the local stream which does not need separate maintenance, and it is possible to overcome the limit of the length of the continuous concrete ramen bridge.
