関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of erection of a bridge (main girder), and more particularly, to an improvement of a hand-rolling type delivery method in which a hand-held device is attached to a tip of a continuously-transmitted bridge and then delivered.

に橋梁を据え付ける工法である。2. Description of the Related Art As a method of erection of a steel bridge on a pier (pier), there is a hand-rolling delivery method in which a hand-held device is connected and attached to a tip of a bridge to be delivered and delivered. In this method, a truss-type or girder-type lightweight hand-held device is connected and attached to the tip of a steel bridge, and a bridge supported by a delivery device or roller on a track or rail is delivered in the bridge axis direction. This is a method of installing a bridge on a pier.

従い上下方向の厚みが薄く形成されている。[0003] The hand-held machine at the tip of the bridge in this hand-operated delivery method is mounted to smoothly deliver the tip of the delivered bridge to a pier located forward in the delivery direction. Therefore, this hand-rolling machine is formed into a truss type or a girder type by using an angle material or the like, and is formed to be thinner in the vertical direction toward the tip end.

の先端が自重で下方に撓み、手延べ機の先端がスムーズ

といった問題が生じる。However, because of the long length of the hand-rolling machine, the hand-held machine is moved away from the feeding device (fulcrum) on the pier on which it is supported. (Close to the pier), the tip of the hand deflects downward due to its own weight, which causes a problem that the tip of the hand-roller does not smoothly reach the feeder installed on the next pier.

的に送出すことは出来ない。[0005] As a means for solving the above problem, when a bridge is sent out, the bridge is sent out upward from the horizontal so that even if the tip of the hand-rolling machine is bent downward, it reaches the next pier. A method is conceivable. When carrying out this method, the height of the feeder must be adjusted in order to send the bridge upward from the horizontal.Therefore, as the feeder, a temporary receiving jack and a vertical jack horizontally moved by the horizontal jack are used. When the bridge is switched and supported by a vertical jack, the vertical jack is sent out by a horizontal jack. Therefore, in this case, the delivery of the bridge is intermittent due to the change of the bridge and the reciprocation of the horizontal jack, and cannot be delivered continuously.

An object of the present invention is to provide a delivery erection method capable of eliminating deflection of a hand-held device and reliably reaching a next pier without sending a bridge upward from a horizontal line.

A pulley that can smoothly guide the wire 3 is used. When the guide members 4 and 5 pull the wire 3 and put the hand-held device 2 on the upper surface of the feed base 7,
The wire 3 is fixed to the bridge 1 in a position that does not get in the way, that is, inside or outside the feed stand 7, corresponding to the position of the guide members 4, 5.

幅に応じて決定する。As shown in FIG. 2, a crawler- type feed stand 7 installed on the upper surface of the pier 6 has a body 7b standing upright supported by a jack 7c on a base plate 7a, and an endless claw is provided on the outer periphery of the body 7b .
The roller 7d is configured to be rotatably wound.
Then, the crawler- type feed table 7 connects the base plate 7a to the pier 6
The crawler 7 on which the bridge 1 is mounted is placed on the upper surface, and the contact resistance between the base plate 7a and the upper surface of the pier 6 is set.
Since the contact resistance between the d and the body 7b is small, a pushing force by a horizontal jack (not shown) or a pulling (pulling) force of the wire 3 acts on the bridge 1, so that the crawler for mounting and supporting the bridge 1 is provided. 7d rotates around the body 7b,
The bridges 1 are sequentially sent out and transferred. The number of crawler- type feed stands 7 installed on the upper surface of the pier 6 is determined according to the width of the bridge 1 to be erected.

７の作用で送出し移送される。Next, a method of erection and erection of a bridge will be described. First, a hand-rolling machine 2 is connected and attached to the leading end of the bridge 1 in the delivery direction, and a wire 3 is connected to the lower surface of the leading end of the bridge 1. It is guided and extended forward through the pulley of the guide member 4 on the pier 6 located forward in the sending direction via the pulley of the guide member 4 attached to the tip of the handwheel 2. Then, by pushing the rear part of the bridge 1 with the horizontal jack and pulling the wire 3 in the sending direction at the same time as pulling the wire 3 or pulling only the wire 3, the bridge 1 is sent and transferred by the action of the crawler type feeder 7.

可能となる。By the way, the delivery of the bridge 1 is accompanied by an increase in the delivery amount from the pier 6 on which the feed base 7 where the delivery is currently being performed is installed to the pier 6 located in the forward direction in the delivery direction. Since the tip of the hand-rolling machine 2 connected to the tip of the bridge 1 moves away from the fulcrum (the feed bar 7 where the feeding is performed), the tip of the hand-rolling machine 2 bends downward and the hand-rolling machine 2 Is located below the upper surface ( crawler surface) of the feed bar 7 on the pier 6. Even if the feeding is continued as it is, the front portion of the hand-rolling machine 2 does not reach the upper surface of the front feed bar 7. , The transmission becomes impossible.

参照）However, according to the erection method of the present invention, the wire 3 connected to the bridge 1 is guided forward along the lower surface of the hand tool 2, and the wire 3 is guided to the guide member 4 at the tip of the hand tool 2 and to the front. Is pulled through the guide member 5 installed on the upper surface of the pier 6, and the hand tool 2, which bends downward, has its tip supported on the lower side by the wire 3 as the next pier 6 approaches, and moves upward. The lower surface of the hand-rolling machine 2 is positioned flush with the upper surface of the feed bar 7 or higher than the upper surface of the feed bar 7, and the leading end of the hand-rolling machine 2 is smoothly transferred onto the feed bar 7. It becomes possible to send out. (FIGS. 2 and 3

Since the wire 3 passes through the member 5, the leading end of the hand-rolling machine 2 is lifted to the position of the guide member 5 where the wire 3 is guided. As a result, the bridge 1 is sent out, and as the tip of the hand-rolling machine 2 approaches the next pier 6, it is lifted upward while being sent out forward, and smoothly moves to the feed stand 7 on the pier.

The same members as those described in the above-mentioned embodiment are denoted by the same reference numerals, and description thereof will be omitted. The above-described method is to pull the wire 3 in the feeding direction, thereby preventing the tip of the hand-rolling machine 2 from being bent downward by the wire 3 while moving the bridge 1 forward. The bridge is advanced by pulling in the wire 3 and the wire 3
In this method, the tip of the hand-rolling machine is prevented from bending downward, and the hand-rolling machine is transferred to the feed stand. For this purpose, a wire pull-in device 8 is attached to the lower surface of the bridge 1 to which the hand-drawing machine 2 is connected at the tip, and the base end of the wire 3 pulled in by the wire pull-in device 8 is a pier 6 located in front of the bridge 1 in the feeding direction. The guide member 9 is fixed on the upper end and the other end (open end side) is substantially the same height as the feed stand 7 installed on the pier 6, the guide member 4 attached to the tip of the hand-rolling machine 2, and the hand-rolling machine It is guided to the bridge 1 side via the lower surface of the bridge 2 and is introduced into the wire drawing device 8 attached to the lower surface of the bridge 1. When the base end of the wire 3 is fixed to the pier 6, it is necessary to sequentially move the fixation of the wire 3 in accordance with the progress of the delivery of the bridge.

When the is operated, since the base end of the wire 3 is fixed, the bridge 1 to which the wire drawing-in device 8 is attached advances while using the wire 3 as a guide, and the tip of the hand-rolling machine 2 approaches the front pier 6. . Then, the wire 3 is sequentially pulled in, the distance between the fixed portion of the wire 3 and the wire drawing device 8 is reduced, and the wire 3 is also tensioned linearly, so that the bending of the tip of the hand-rolling machine 2 is gradually reduced. As a result, the vehicle reaches the feed stand 7 on the pier 6, and the transfer is performed smoothly.
