Referring to FIG. 1, the crossing and extension bridges to which the construction method according to the present invention is applied are provided with pierced columns 10 made of piles of steel pipe piles vertically embedded in the ground so as to be spaced apart by a predetermined distance, A fixing unit 30 is provided on an upper portion of a head reinforcing member 11 provided on an upper portion of the head reinforcing member 11 with a vibration absorbing pad 20 made of high elastic rubber interposed therebetween, 40) are installed and fixed and fixed in position, and a mold 50 (50) made of I-shaped steel (or H-shaped steel or the like) is provided on the upper portion of the lateral direction coping bracket 40 provided on the plurality of bridge columns 10 provided in the longitudinal direction of the bridge And a deck 80 is provided laterally thereon. The deck 80 is mounted on the deck 80 in the longitudinal direction, The balustrade (90) is installed at both ends of the deck. It is one structure.

Although the embodiment of the present invention illustrates a structure in which the lateral coiling brackets 40 extending in both lateral directions are provided around the pillar columns 10, It is also applicable to a structure in which a lateral directional coping bracket 40 is provided extending only in one lateral direction.

FIG. 1 shows a case where there is no construction error e between a planned center line P where an original pier should be installed and an actual center line R where an actual pier is installed. As shown in FIG. 12, P and the actual center line R when a construction error e occurs in the center line R will be described below.

Referring to FIG. 2 showing a pile (pile) and a head reinforcement member of the transverse and extension bridges of FIG. 1, an embodiment of the present invention illustrates construction of a pillar column 10 using steel pipe piles. However, the material and the structure of the pier may be a pile or pile, and the material and the structure of the pier are not necessarily limited thereto.

At the upper end of the steel pipe pile, a head reinforcement member 11 is provided as a concrete material. The head reinforcement member 11 can be poured after the steel pipe pile is buried in the ground. Such a head reinforcement member may be manufactured by arranging reinforcing bars at the upper end of a steel pipe pile and pouring concrete, or by assembling the head reinforcement portion with a rigid material. The height of the upper surface of the head reinforcement member 11 constituting the upper end surface of the bridge pier can be precisely adjusted when the head reinforcement member is poured into the concrete in the state where the steel pipe pile is buried in the ground or the head reinforcement is made of a rigid material. . Therefore, it is not necessary to cut the head of the bridge pillar to adjust the height of the top surface of the bridge pier. According to the present invention, the height of a plurality of piers can be adjusted in the process of installing the steel pipe pile and the head reinforcement member.

As shown in the side view of the head reinforcement member in installing the head reinforcement member 11, a flat type buried nut 121 is installed. The position of the buried nuts 121 corresponds to the position of the through hole 211 formed in the side surface 21 of the vibration absorbing pad 20 to be described later, (311). In the embodiment of the present invention, a total of four nuts 121 are embedded in two rows and two columns on the side surface of the head reinforcement member 11 is illustrated. However, the mounting positions and the number of the nuts 121 are not limited thereto.

3 to 5 showing a front view, a side view, and a plan view of the vibration absorbing pad covering the top and side surfaces of the head reinforcing member shown in FIG. 2, the vibration absorbing pad 20 Is made of a highly elastic rubber material and has a "C" shape having an upper surface 22 and both side surfaces 21.

A through hole 211 is formed in the pad side surface 21 at a position corresponding to the position of the nut 121 buried in the side surface of the head reinforcement member 11 described above. At this time, the size of the through hole is much larger than the diameter of the bolt 123 to be fitted to the buried nut 121, so that it can cope with manufacturing errors and construction errors. In addition, a through hole 221 is formed in the pad upper surface 22, which is much larger than the diameter of the upper surface bolt 131 to be described later, so that it can cope with a manufacturing error and a construction error. Since the position of the upper surface bolt 131 provided on the upper surface of the head reinforcement member 11 can be changed according to the result of the positional correction of the lateral direction coping bracket 40 to be described later, ) Should be made larger by reflecting this point.

6, the fixing unit 30 includes a side fixing plate 31 fixed to the side surface of the head reinforcing member and fixed to the side fixing plate 31 (Widthwise direction) of the bridge. The bottom extension plate 32 extends outwardly in the widthwise direction of the bridge. The side fixing plate 31 and the bottom extending plate 32 can be manufactured by welding a steel plate. The fixing unit 30 is provided with a pair of side plates 31 and a pair of side extension plates 32 for connecting diagonally opposite sides of the bottom plate 32 to reinforce the fastening strength of the bottom extension plate 32 to the side fixing plates 31 A support plate 33 is further provided. As will be described later, the bottom extending plate 32 is configured to abut against the lateral directional coping bracket 40 to be welded to each other to transmit the load of the lateral directional coping bracket 40 to the head reinforcement member 11, Tightly coupled.

A bolt hole 311 is formed in the side fixing plate 31. This is formed at a position corresponding to the position of the buried nut 121 of the head reinforcement member 11 described above.

7 showing the state in which the vibration absorbing pad and the fixing unit are fixed to the head reinforcing member of Fig. 2, the upper surface and the side surface of the head reinforcing member 11 are covered with the upper surface and the side surface of the vibration absorbing pad 20 And the fixing unit 30 is fastened and fixed to the side surface of the head reinforcing member 11 with the vibration absorbing pad 20 interposed therebetween. The side bolts 123 constituted by the high tension bolts pass through the bolt holes 311 of the fixed unit and the through holes 211 of the vibration absorbing pad when the fixed unit 30 is fastened, A vibration absorbing bushing 122 in the form of a washer is interposed between the side bolt 123 and the buried nut 121 at this time.

Referring to Fig. 8, which shows a lateral directional coping bracket fixed to the head reinforcement member of Fig. 7, the lateral direction coping bracket 40 includes an upper plate 41 extending laterally in the form of a horizontal plate, An intermediate plate 42 extending transversely from both sides of the lower surface except for the central portion of the intermediate plate 42 and a lower plate 43 extending laterally from the lower surface of the intermediate plate 42 Respectively. That is, the middle portion of the lateral direction coping bracket 40 is composed of only the upper plate 41 which is a horizontal flat plate, but a horizontal upper plate 41, a vertical middle plate 42, (43).

In the space formed by the horizontal upper plate 41, the vertical middle plate 42 and the inclined lower plate 43, flat plate-like side plates 44, 45, 46, 47, which are spaced apart from each other along the lateral direction of the coping bracket. The distance between the upper plate 41 and the lower plate 43 is gradually narrowed toward the outer side from the central portion so that the distance between the upper plate 41 and the lower plate 43 is smaller than the distance between the upper plate 41 and the lower plate 43, The area of the third side plate 46 is smaller than that of the second side plate 45 and the area of the fourth side plate 47 is smaller than the area of the third side plate 46. [

9 showing the cross-sectional view of Fig. 8B, the first side plate 44 is integrally provided in a form blocking the internal area defined by the three plates 41, 42 and 43, and the lateral coiling brackets 40 Is mounted on the head reinforcement member 11, the first side plate 44 faces the side surface of the head reinforcement member. An access hole 445 is formed in the first side plate 44 at a position corresponding to the nut 121 buried in the side surface of the head reinforcement member and is positioned at a lower portion of the access hole 445, A through hole 441 is formed at a position facing the side surface fixing plate 31 of the fixed unit 30 fixed to the side surface of the reinforcing member.

 The side bolts 123 which are fastening elements for fixing the fixing unit 30 to the side surface of the head reinforcement member 11 are accessed through the access hole 445 from the outer space of the lateral direction coping bracket 40 . This is achieved by aligning the lateral directional coping brackets 40 with respect to the planned center line P of the piers and then fixing the lateral directional coping brackets 40 and the fixed unit 30 by welding or the like, It can be utilized when the lateral coiling bracket 40 needs to be separated from the head reinforcement member 11 for maintenance.

Next, a camber adjusting nut 442 is welded to the through hole 441 of the first side plate 44 so that the center of the through hole 441 is aligned with the through hole 441. The camber adjusting bolt 443 inserted through the through hole 441 is screwed to the camber adjusting nut 442, as will be described later with reference to FIG.

The lateral coiling bracket 40 exemplified in the embodiment of the present invention exemplifies the coiling bracket 40 which is extended in both lateral directions based on the central portion of the head reinforcement member which is placed on the upper surface of the head reinforcement member, A coping bracket 40 extending only in one direction with respect to the center portion is also applicable.

10, which is an enlarged view of a portion A in Fig. 1, and Fig. 11, which is a plan view of a state in which a lateral directional coping bracket is placed on a head reinforcement member, to explain a lateral position adjustment principle of the lateral direction coping bracket 40 do.

First, a lateral directional coping bracket 40 is placed on an upper portion of a head reinforcement member (strictly, a vibration absorbing pad lying on the upper portion of the head reinforcement member) in the state shown in FIG. The upper bolt 131 is attached to the upper surface of the head reinforcement member through the elongated hole 411 formed in the center portion of the upper plate 41 and the through hole 221 of the vibration absorbing pad, which are placed on the upper surface of the head reinforcement member 11. A fixing nut 133 is fastened to the upper part of the bolt 131 so as to prevent the elongated hole 411 from escaping from the bolt 131 so that the lateral directional coping bracket 40 And temporarily fixed to the upper portion of the reinforcing member (11). In this temporarily fixed state, there is a clearance in the long hole 411, so that the lateral directional coping bracket 40 can be moved back and forth and left and right despite the presence of the bolt 131. Since the lower portion of the lateral direction coping bracket 40, that is, the lower plate 43, is supported on the upper portion of the bottom extension plate of the fixed unit 30 while the lateral direction coping bracket 40 is stuck to the bridge pier, The sagging of both the blade portions of the bracket 40 due to their own weight is prevented.

In this state, the camber adjusting bolt 443 is inserted through the through hole 441 of the first side plate 44 of the lateral direction coping bracket 40 and screwed into the camber adjusting nut 442, The bolt 443 is rotated so that the tip end of the camber adjusting bolt 443 comes into contact with the surface of the side surface fixing plate 31 of the fixed unit 30. [ In this state, the camber adjusting bolts 443 on both sides (the left and right sides around the head reinforcing member) are tightened or loosened to adjust the lateral position of the lateral direction coping bracket 40 with respect to the head reinforcing member. When the actual center line R of the bridge pier actually installed with respect to the planned center line P of the bridge pier is deviated by the construction error e as shown in Fig. 12, the lateral coiling bracket 40, (E) to be aligned with the planned center line (P).

Further, the longitudinal coiling bracket 40 can be moved forward and backward as well as horizontally by the elongated hole 411 of the upper plate 41, and the longitudinal position of the lateral coiling bracket 40 is also aligned with the position .

After the alignment with the lateral coiling bracket 40 is completed, the upper bolt 131, which is an anchor bolt, is inserted through the bolt hole 412 of the upper plate 41 and the through hole 221 of the vibration absorbing pad 20, The lateral direction coping bracket 40 is firmly fixed to the head reinforcement member 11 by tightening the fixing nut 133 with the vibration absorbing bushing 132 interposed therebetween. In addition, the temporary fixing member (not shown) temporarily fixed to the elongated hole 411 of the upper plate 41 is removed, and the fixing nut 133 is fastened with the vibration absorbing bushing 132 interposed therebetween.

When the center portion of the lateral direction coping bracket 40 is fixed to the head reinforcement member and the first side plate 44 is further moved away from the side of the head reinforcement member by further tightening the camber adjustment bolt 443, The end of the bracket 40 is inclined in the u-direction as shown in Fig. The angle at which the side wing portions of the lateral coiling brackets 40 are raised is the sum of the angles of the mold 50, the idler 60, the joist 70, the deck 80, (90), and a load that is expected to reside on the deck and predicts the extent to which the lateral wing portions of the lateral coping bracket (40) are sagged by this load and compensates for this in advance.

After the camber adjusting bolts 443 are further tightened to compensate for the expected deflection of the lateral directional coping brackets, the lateral directional positioning of the lateral directional locking brackets 40 And the bottom extension plate 32 are fixed by welding (W).

After the installation of the lateral coiling bracket 40 is completed in this way, the above-described upper molds such as the mold, the loosening, and the joist are sequentially installed. The mold 50 is arranged parallel to the longitudinal direction of the bridge and spaced several in the lateral direction. The mold is fastened to the upper plate 41 of the lateral direction coping bracket 40 through bolts-nuts 52 and 53 through elongated holes formed in the lower web portion (formed in the longitudinal direction of the mold) .

A bottom member of the bridge is installed on the upper part of the mold 50. In the present invention, as an example of the bottom member, it is exemplified that the loosening 60 is raised in the transverse direction, the joist line 70 is provided in the longitudinal direction on the loose 60, and the deck 80 is installed on the joist line . However, the structure of the bottom member is not limited thereto, and it is needless to say that the bottom member may be constructed of various structures such as a car or a car which is packed with various concrete or asphalt or made of steel, or a combination thereof.

After the bottom member is thus constructed, the handrail 90 is installed longitudinally along the end of the bottom member.

When it is necessary to separate the lateral directional coping bracket 40 from the head reinforcement member 11 because maintenance is required after the bridge is installed and used as shown in FIG. 12, the lateral direction coping bracket 40 is first installed on the upper side of the lateral direction coping bracket 40 The upper structures 50, 60, 70, 80 and 90 are removed and the side bolts 123 are unscrewed through the access holes 445 formed in the first side plate 44 of the lateral coiling bracket 40, The lateral direction coping bracket 40 and the fixed unit 30 integrally welded and fixed thereto are detached from the head reinforcement member 11 together when the fixing nut 133 on the upper side of the lateral direction coping bracket 40 is loosened Can come out.

Fig. 13 is a view showing an embodiment of a bridge to which a lateral coiling bracket 40 extending in only one lateral direction is applied. A pile or a pile 10 is inserted and fixed on a slope or a bottom surface of a river, a head reinforcement member 11 is installed on the upper end of the pile, and a lateral directional coping bracket 40 are installed.

The position of stowing the file is located close to the roadway, corresponding to the shape of the lateral coping bracket 40. If the file is placed close to the road, the supporting force can be improved because the file can be put relatively deeply.

The installation of the lateral coping bracket 40 and the installation of the floor member and the handrail 90 on the upper part thereof are the same as those of the above-described embodiment, and the description thereof is omitted in order to avoid redundancy. This bridge is constructed by avoiding the roadside trees on slopes and high-altitude road slopes and riverside slopes, roadside roads where roadside trees are planted, and installing the piles without affecting the growth of existing roadside trees. After the construction, it is possible to extend the width of the road by flattening back the bridge between the bridge and the roadway. It is also possible to utilize it as a resting space by providing a green space and improve the accessibility and convenience to road users and the sidetrackers.

Fig. 14 shows an embodiment of a transverse and an extension bridge to which two side lateral directional coping brackets using a bifurcation are applied. It is a matter of course that the transverse direction coping bracket 40 of the present invention is also applicable to a bimetallic bridge as shown.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the scope of the invention is not limited to the disclosed exemplary embodiments. It is obvious that a transformation can be made. Although the embodiments of the present invention have been described in detail above, the effects of the present invention are not explicitly described and described, but it is needless to say that the effects that can be predicted by the configurations should also be recognized.
