Abstract

PROBLEM TO BE SOLVED: To provide a working platform capable of adjusting a height dimension of a column without preparing many kinds of columns different in a length dimension, and capable of freely adjusting a height dimension of an upper end part of the column even in a slight height dimensional difference.SOLUTION: Since a horizontal member 9 is rotatably connected to a column 2, an adjacent column 2 can be vertically moved. Thus, the horizontal member can adjust an upper end part of the adjacent column 2 so as to have a height difference, or to become the same height, and a height position of the upper end part of the column 2 can be steplessly set. Thus, an inclination of a work floor 51 can be freely set, and even when constructing a height difference-present road by a working platform 1, an up-grade and a down-grade can be freely set, and a delicate inclination angle adjustment also becomes possible, and can thereby avoid inconvenience such as a step difference formed between the working floor 51 and the road opposed to the working platform 1.

As this type of gantry, there is one described in Patent Document 1, for example, which is provided with a plurality of support columns standing up and down in the left-right and front-rear directions, with a space in the vertical direction between adjacent support columns. The horizontal members are connected so that they are next to each other. The struts and the horizontal members are arranged so as to form a quadrangular frame between the adjacent struts and the horizontal member, and the braces are spanned between the diagonal portions of the quadrangular frame. A long plate-like panel or the like is laid on the upper end of the column to provide a work floor.

A construction method of the gantry 1 will be described.
The gantry 1 has its height, the inclination direction of the work floor 51, the inclination angle, and the like determined based on the survey results at the construction site.
The support columns 2 are arranged in a standing state at a predetermined interval in the depth direction or the width direction. The lower end of the lowermost support column 2 is inserted into the ground.

Next, as shown in FIG. 7, the pair of column-side connection portions 5 are sandwiched between the pair of horizontal-member-side connection portions 13 provided at one end of the horizontal member 9, and the column-side connection holes 7 and the horizontal material are arranged. The side connection hole 15 is opposed.
Then, a finger is put on the pair of finger hooks 45 of the connector 31 to grip the bending portion 39 and the finger hook 45, and the bending portion 39 and the finger hook 45 are elastically deformed to move the pair of connecting shafts 33 away from each other. (See FIG. 6). Next, the pair of connecting shafts 33 are opposed to the pair of column-side connecting holes 7 and the pair of horizontal member-side connecting holes 15, and the hand holding the connector 31 is loosened. Then, the pair of connecting shafts 33 are inserted into the pair of column-side connecting holes 7 and the pair of horizontal member-side connecting holes 15 by the elastic force of the bending portion 39 and the finger hooking portion 45, and the stopper 35 is inserted into the horizontal member-side connecting hole 15. It is press-contacted to the periphery. Thereby, the horizontal member side connecting part 13 of the horizontal member 9 is connected to the column side connecting part 5 of the column 2, and one end of the horizontal member 9 can be rotated with respect to the column 2 with the connecting shaft 33 as a fulcrum. Connected to

The horizontal member 9 having one end connected to the column 2 is rotated, and the horizontal member side connection hole 15 of the pair of horizontal member side connecting portions 13 provided at the other end is connected to the column side of the adjacent column 2. Align with the connecting hole 7. Then, in the same manner as the connecting operation of the one end portion of the horizontal member 9, the pair of connecting shafts 33 of the connecting tool 31 are inserted into the pair of column-side connecting holes 7 and the pair of horizontal member-side connecting holes 15. The strut side connecting portion 5 of the matching strut 2 and the pair of horizontal member side connecting portions 13 on the other end side are connected.
A pair of horizontal members 9 are connected to the column 2 with a space in the vertical direction, and the pair of horizontal members 9 and the pair of columns 2 constitute a parallelogram frame 16.

Since the horizontal member 9 is pivotally connected to the support column 2 with the connecting shaft 33 as a fulcrum, the frame 16 is deformed so that the pair of support columns 2 move up and down, and each support column 2 is set to an arbitrary height. The height position of the upper end portion of each column 2 can be freely set. Thus, it can adjust so that a height difference may be made in the upper end part of the adjacent support | pillar 2, or it can adjust so that it may become the same height.
By moving adjacent struts 2 in the vertical direction, the shape of the frame 16 becomes not only the rectangle shown in FIG. 8 but also various parallelogram shapes as shown in FIGS. Is inclined.

In order to fix the adjacent strut 2 adjusted to an arbitrary height by the brace 17 at that position, first, the small-diameter pipe 21 inserted into one end of the large-diameter pipe 19 is slid, and the strut 2 and the horizontal support are placed. The length dimension of the braces 17 is adjusted to the distance between the diagonal portions of the frame 16 constituted by the material 9.
Then, the large-diameter pipe 19 (or the small-diameter pipe 21) is rotated so that the connecting portions 27 and 29 attached to the large-diameter pipe 19 and the small-diameter pipe 21 are bent in different directions. Next, the large-diameter pipe-side connecting hole 23 and the small-diameter pipe-side connecting hole 25 are opposed to each other, and in this state, a wedge 47 is inserted into the large-diameter pipe-side connecting hole 23 and the small-diameter pipe-side connecting hole 25 to prevent detachment, The large-diameter pipe 19 and the small-diameter pipe 21 are connected and fixed, and the brace 17 is held in a state of a predetermined length.
In this way, the brace 17 can be expanded and contracted, and its length dimension can be freely changed according to the length dimension between the diagonal portions of the frame 16 constituted by the support column 2 and the horizontal member 9.

The pair of connecting shafts 33 of the connecting tool 31 are connected to the shaft insertion hole 11 and the connecting hole 28 in the same manner as the method of connecting the horizontal member side connecting part 13 of the horizontal member 9 to the column side connecting part 5 of the column 2 described above. It inserts into the (connection hole 30), connects the horizontal member 9 and the connection part 27 (connection part 29), and the adjacent support | pillar 2 adjusted to arbitrary height positions by the brace 17 is fixed in the position.

By repeating the above operation, the struts 17 are stretched between the diagonal portions of the frame 16 in the depth direction or the width direction, and the adjacent struts 2 adjusted to an arbitrary height position are fixed at that position.
Further, the frame 16 is assembled in the depth direction, the width direction, and the upward direction, and when the upper end reaches a desired height dimension, a long panel 49 or the like is laid on the upper end of the column 2 to configure the work floor 51. To do.

  Thus, since the horizontal member 9 is rotatably connected to the support column 2, the adjacent support columns 2 can be moved up and down. Therefore, the height position of the upper end portion of the support column 2 can be set in a stepless manner by adjusting the upper end portion of the adjacent support columns 2 so as to have a height difference or adjusting the height to be the same. Is possible. Therefore, the inclination of the work floor 51 can be freely set, and even when a road with a height difference is constructed by the gantry 1 as shown in FIG. Therefore, it is possible to avoid such inconvenience that a step is formed between the work floor 51 and the road facing the gantry 1.
