Description

Formwork for constructing support walls on light rail road for installing guideway}

The present invention relates to a formwork for constructing a concrete post of an Automated Guideway Transit (AGT) with a guide track type, and more particularly, after positioning an anchor bolt mounted on a concrete post of a light rail roadbed to match the trajectory of the guide track, It relates to a formwork for constructing a concrete post of a light railroad that can cure the light rail, which can improve the construction precision of the guide track and reduce the construction process of the concrete post.

In general, the light rail is defined as a means of public transportation with a transport capacity intermediate between a subway map and a public bus, and is divided into steel wheel AGT, rubber wheel AGT, monorail, and streetcar.

Light rail is divided into steel wheels and rubber wheels. The steel wheel system travels on railroad tracks, and the rubber wheel system uses guide rails installed on both poles of the roadbed for track travel.

Most of the light rail lines constructed underground and elevated in cities are designed with straight and flat surfaces, but due to the nature of the light rail, many vertical and horizontal curves change. Therefore, in the case of AGT with rubber wheels, the tires and guide rollers must travel on the running track and the guide track, respectively. For the safety of the light rail train, the running track and the guide track must have an appropriate inclination corresponding to the lateral and longitudinal inclination of the track. You have to build it precisely to have it.

1 is a schematic front view showing the track structure of a general rubber wheeled light rail W; Figure 2 is an exemplary view showing a state in which the anchor bolts are drilled on the posts after adjusting the inclination of the guide track in the track structure of the rubber wheeled light rail according to the prior art.

As shown in the drawing, concrete posts 206 are constructed on both sides of the roadbed 200 . On the upper surface of the roadbed 200, a running path 204 in which the rubber wheel 202 of the light rail W is in contact is installed, and a guide track 208 for adhering the guide roller 210 to the concrete posts 206 on both sides is provided. is installed

The curved portion of the rubber wheel AGT traveling path has an inclination in an inclined direction, and the overall height of the post 206 is also changed according to the inclination in the inclined direction. In addition, the height difference between the left and right guide tracks 208 installed on the post 206 is about 200 mm, and the anchor bolt 212 for fixing the guide track is also tilted to match the height difference of the guide track, and then the post (206) should be mounted. Unexplained symbol T indicates the trajectory height.

In the track configuration of the light rail, the construction method of the rubber wheel AGT is to install the guide track 208 on the side of the roadbed 200 in the state that the running path 204 installed on the roadbed 200 is constructed according to the design trajectory. A concrete post 206 will be constructed.

In the construction of the concrete post 206 , the concrete is poured by first installing a formwork, and the guide plate 212 is mounted on the track after curing. And drilling an anchor hole 206a with a drilling device (DR) in a direction orthogonal to the design trajectory (longitudinal and lateral gradient in which the track changes linearly), and anchor bolts in the anchor hole 206a It goes through a series of processes to mount the guide track 208 by driving it.

In the construction of the guide track of the concrete post, the deviation of the guide track 208 on both sides is eliminated when the anchor bolts are precisely embedded in the post 206 according to the lateral gradient of the guide track. In order to eliminate the deviation of the guide track on both sides, as shown in FIG. 2 , the anchor hole 206a was constructed in a state where the inclination θ was measured from the reference line L2 of the guide plate 212 . However, in this construction method, even if the anchor hole 206a is precisely constructed depending on the guide plate 212 and the drilling equipment DR, the drilling deviation on both sides occurs. This is due to the deviation due to manpower construction, which proves that it is very difficult to precisely drill the anchor hole 206a in a direction orthogonal to the running path in response to the lateral gradient of the track. Unexplained symbol O is the central axis of the guide plate.

In order to overcome this problem, in the prior art, a formwork for a support in which a guide track is installed has been proposed in Korean Patent No. 10-1034752. Figure 3 shows a cross-sectional view of the formwork for the support in which the guide track according to the prior art is installed.

As shown in FIG. 3, this prior patent mounts the rear plate 226 with the second through hole 226a on the formwork plate 222 in which the vertically long moving hole 222a is formed, and the rear plate A front plate 224 having a first through hole 224a is mounted on the 226, and a guide member 230 having a guide hole 230a formed thereon is installed on both sides of the front plate 224. . In the formwork, the moving hole 222a, the first through hole 226a, and the second through hole 224a communicate with each other, and the anchor bolt B is inserted into the communication path and the guide hole of the guide member 230 is inserted. Concrete can be poured after adjusting the inclination of the anchor bolts to fit the lateral gradient of the design track while moving the front plate 224 and the rear plate 226 up and down along (230a). Here, the vertical movement of the front plate 224 controls the height of the anchor bolt, and the vertical movement of the rear plate 226 adjusts the inclination angle.

In the above-mentioned prior patent, the through-holes 224a and 226a are formed at right angles to the front plate 224 and the rear plate 226, and the through-holes 224a and 226a are formed larger than the diameter of the anchor bolt (B). have. This structure not only limits the angle of inclination of the anchor bolt, but also fits the design track even if the rear plate 226 moves up and down along the guide hole 230a of the guide member 230 because the anchor bolt flows in the through hole. It is very difficult to give an inclination to the anchor bolt, and it is not easy to adjust the inclination. Even if the through-holes 224a and 226a are pre-drilled to have an arbitrary gradient in accordance with the design track, an error in the design track may occur depending on the site conditions, so that the deviation of the guide track on both sides inevitably occurs. In this case, there is a problem in that the through-holes 224a and 226a of the front plate 224 and the rear plate 226 must be drilled again by correcting the inclination by the error of the design trajectory.

The structural problem of these prior patents lowers the construction precision and construction efficiency of the formwork cured by inserting anchor bolts into the concrete posts.

In addition, both sides of the roadbed are subjected to chamfering to prevent the edges from being broken. The post form for mounting the guide track according to the prior art requires an additional process in which a face neck for chamfering the edge of the side wall must be separately installed. .

Republic of Korea Patent No. 10-0910912 (registered on July 29, 2009) Republic of Korea Patent Registration No. 10-0920292 (Registered on September 28, 2009) Republic of Korea Patent No. 10-1034752 (Registered on May 4, 2011)

Therefore, the present invention is proposed to solve the above-mentioned problems, and by installing an angle adjustment form and a height adjustment form on the front plate of the formwork, an error occurs in the design trajectory of the guide rail according to the on-site construction of concrete posts on both sides of the roadbed.
