  DESCRIPTION OF EMBODIMENTS Embodiments of a platform end formwork and a platform construction method according to the present invention will be described below in detail with reference to the drawings. Note that the present invention is not limited to the embodiments.

  As shown in FIGS. 1 and 2, a platform end formwork 10 according to the present invention is a platform end formwork provided in contact with a track, and is an L-shape comprising a side face 12 and a bottom face 14. It consists of an angle 16 (formwork member) having a cross section and a base member 18 disposed on the back side of the bottom surface 14.

  The bottom surface 14 of the angle 16 is provided with at least one elongated hole 20 extending in the direction perpendicular to the track X (direction perpendicular to the side surface 12), and the upper portion of the bolt 22 of the base member 18 is inserted into the elongated hole 20. It is. The bolt 22 and the bottom surface 14 are clamped and fixed by being sandwiched by a double nut 26 via a washer 24. A plurality of the long holes 20 and the bolts 22 may be provided at intervals in the long direction along the ridge line 28 of the angle 16 (in the direction perpendicular to the paper surface in FIG. 1).

  As the dimension and material of the angle 16, for example, a metal material such as a stainless steel having a plate thickness of about 1.5 mm × 30 mm × 150 mm can be used. The length in the longitudinal direction of the angle 16 may be configured to be about 3 m, for example.

  The base member 18 is composed of a horizontal plate 30 (flat plate) with a bolt 22 projecting from the upper surface, and the angle 16 can be moved in two directions, ie, a trajectory perpendicular direction X and a height direction Y (a direction perpendicular to the bottom surface 14). It is for fixing to. As shown in FIG. 1, the horizontal plate 30 of the base member 18 is fixed to the upper surface of the platform top end 4 of the platform end 2 with a bolt 32 to prevent the angle 16 from jumping up.

  Thus, since the platform end formwork 10 of the present invention has a structure that allows fine adjustment of the position, the formwork 10 is installed on the platform end 2 before the track laying is completed, and the track By finely adjusting the height and distance from the track after laying is completed, the entire construction period can be shortened compared to the case of using a conventional wooden formwork, and the construction error of the platform end 2 Can be suppressed.

  Next, the construction method of the platform end 10 according to the present invention will be described.

  In this construction method, the platform end 2 is constructed using the platform end formwork 10, and the base member 18 is fixed on the frame top end 4 of the platform end 2 as shown in FIG. 1. The bottom surface 14 of the angle 16 is disposed on the top end 4 of the housing, and the side surface 12 of the angle 16 is disposed on the side surface 2a side of the platform end 2 so that the angle 16 can be arranged in two directions X and Y as required. The position is adjusted by moving it.

  Specifically, as shown in FIGS. 3 and 4, the platform end formwork 10 is installed on the platform end 2 prior to the track work. In this case, using a building limit measuring ruler or the like, it is installed in accordance with the reference ink of the track provided in advance.

  Next, when the track construction is completed and the position of the track is determined, the height and the separation position of the platform end 2 with respect to the track are set to predetermined construction target values as shown in FIGS. 5 and 6. Then, the double nut 26 is loosened and the angle 16 is moved in the two directions X and Y, the relative position from the base member 18 fixed to the top end 4 of the housing is finely adjusted, and the double nut 26 is fastened and fixed again. . By doing so, it is possible to start the construction of the platform end 2 without waiting for the completion of the track construction, in particular, the troublesome formwork installation, and to shorten the construction period of the entire construction.

  Subsequently, as shown in FIG. 7, the non-shrink mortar 34 is filled between the top of the casing 4 and the bottom surface 14 of the angle 16, and an adjustment mortar 36 is placed on the bottom surface 14 of the angle 16. The platform end 2 is completed by bonding the panel 38. The platform end formwork 10 is finally embedded in the platform end 2.

  Thus, according to the platform end construction method of the present invention, the formwork 10 is installed on the platform end 2 prior to the completion of the track laying, and the height and separation position are slightly adjusted after the track laying is completed. By performing the adjustment, the construction period of the entire construction can be shortened, and the construction error of the platform end 2 can be suppressed. In addition, since the platform end formwork 10 is finally embedded in such a manner that the side surface 12 is exposed to the outside, if the formwork 10 is made of stainless steel or the like, a metallic luster can be obtained to improve aesthetics. Can contribute.

  Next, an example of construction management (standard value management) of the platform end according to the present invention will be described.

  As shown in FIG. 8, in the case where the gauge between the tracks 8 is 1435 mm and the design value h of the platform end 2 is 1250 mm higher than the track level EL, the construction must never exceed 1250 mm. Therefore, for example, the design value of −5 mm is set as the construction target value, and the upper and lower limit width is set to ± 5 mm. Therefore, the construction management is performed with a finished size of 1245 mm ± 5 mm (1240 to 1250 mm).

  Further, as shown in FIG. 9, when the distance between the tracks 8 is 1435 mm and the design value d apart from the platform end 2 is 1760 mm from the track center CL, the construction must not be less than 1760 mm. Therefore, for example, this design value ± 5 mm is determined as the construction target value, and the upper and lower limit width is set to ± 5 mm. Therefore, construction management is performed with a finished size of 1765 mm ± 5 mm (1760 to 1770 mm).

  When standard value management is performed, first, the platform end formwork 10 is attached to the platform end 2 with reference to a trajectory reference ink provided in advance. In this case, the position of the mold 10 is adjusted to some extent so as to be close to the above construction target value. Then, after the track laying is completed, the angle 16 is moved in two directions, X and Y, and fine adjustment is made to a position that strictly observes the standard value (finished dimension). As a result, it is possible to carry out construction that shortens the construction period and improves the construction accuracy.

  As described above, the platform end formwork according to the present invention is a platform end formwork provided in contact with the track, and has an L-shaped cross section formed of a side surface and a bottom surface. It consists of a member and a base member that movably fixes the mold member in two directions, a direction perpendicular to the side surface and a direction perpendicular to the bottom surface. Thus, by finely adjusting the height and separation of the platform end after completion of track laying, the construction period of the entire construction can be shortened, and construction errors at the platform end can be suppressed.

  The platform end construction method according to the present invention is a method for constructing a platform end using the platform end formwork described above, wherein the base member is placed on the top end of the platform end. The bottom surface of the mold member is fixed and the side surface of the mold member is disposed on the side surface side of the platform end, and the mold member is moved in the two directions as necessary. adjust. For this reason, it is possible to shorten the work period of the entire construction by constructing the formwork prior to completion of track laying and finely adjusting the height and separation of the platform end after completion of track laying, and The construction error at the platform end can be suppressed.

  As described above, the platform end formwork and the platform end construction method according to the present invention are useful for construction of a platform end provided in contact with a track such as a railway station. It is suitable for reducing construction errors.
