[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevating frame material for a narrow framed scaffold.

[0002]

2. Description of the Related Art Conventionally, a frame scaffold generally has a width of 120 mm.
There are two types, one with a wide width of 0 mm and the other with a narrow width of 600 mm. In the case of a wide framed scaffold, it is possible to install a narrow stair frame in the framed scaffold using one half of the framed frame. On the scaffolding, there is no room to attach such a staircase frame, so a staircase of another frame is assembled at the right place and attached to it.

[0003]

[Problems to be solved by the present invention] However, when only a narrow framed scaffold is used due to location conditions, stairs cannot be attached, and it is a problem in reality. In addition, even if a staircase with a separate frame can be assembled and attached, the position of the staircase may be limited in place, and a considerable detour may be required for ascending and descending. The present invention is intended to solve such a problem.

[0004]

In order to achieve the above object, the present invention provides: 1) a framed scaffold A having a height adapted to the floor height;
A ramp 1 having a plurality of lower and upper ends capable of being connected to each other, and a hook 11 provided at an appropriate position on the back of the upper portion; and 2) a support means 21 for receiving an end of the ramp 1 at an intermediate portion.
And a support bar 2 having clamps 22 at both ends and removably erected below the columns Ba between the adjacent building frames B with the clamps, and 3) a lifting hatch 31 at an intermediate portion. An insertion portion 32 for inserting the upper portion of the ramp 1 is formed on one side of the lifting hatch, a locking portion 33 for detachably engaging the hook 11 is formed, and the lifting hatch 31 is openable and closable. Nasty treads
And a lifting hatch-equipped cloth frame 3 equipped with the arm.

[0005]

In use, a narrow framed scaffolding A is provided with a narrow vertical hatch on each of the top horizontal bars Bb of the narrow building frames B adjacent to each other through the upper and lower floors at a common point. The fabric frame 3 is assembled to form an elevating shaft, and the trap 1 is inserted into each of the insertion portions 32 of the fabric frame 3 with the hatch, so that the support means 21 on the rear surface is engaged with the locking portions 33.
, And the ramps 1 are connected in series, and a support bar is provided at the lower part of the column Ba between the lowermost frame B and the column Ba between the uppermost frame B. The upper end of the lowermost ramp 1 and the upper end of the uppermost ramp 1 are supported by the supporting means 21 at the intermediate portion of each support bar by fastening the clamps 22 with the clamps 22 facing upward and downward. When the ramp 1 is raised and lowered, the tread plate 34 is rotated to open the lifting hatch 31 and pass through the lifting hatch. Thereafter, the lifting hatch 31 is closed again,
The step board 34 is provided on a cloth board.

BRIEF DESCRIPTION OF THE DRAWINGS The drawings show an embodiment of the present invention. In the figure, 1 is a ramp incorporated in a narrow framed scaffold A, 2 is detachably mounted on the lower part of a column Ba between adjacent narrow frames B, and an end of the ramp 1 is attached. The supported support bar 3 has an elevating hatch 31 for inserting and engaging the ramp 1, and the elevating hatch 31 is provided with an openable and closable tread plate 34 so that adjacent narrow building frames B Top horizontal pole Bb
With a narrow width hatch cloth frame that is detachably assembled to
The lifting hatch cloth frame 3 is disposed on each of the upper and lower floors to form a lifting shaft. Reference numeral 4 denotes an openable and closable handrail for partitioning the elevating shaft disposed in the middle of the column Ba of the building frame B adjacent to the elevating shaft. Curing wire mesh with frame. The ramp 1 has a height adapted to the floor height of the framework scaffold A, has a lower end and an upper end formed so as to be able to be connected to each other, and has a pair of left and right hooks 11 protruding downward at appropriate locations on the upper surface. This ramp 1 connects a plurality of frames scaffolding A in series according to the floor number. Support bar 2
Support means 21 for receiving an end of the ramp 1 at an intermediate portion.
A barrel tube is provided, and clamps 22 are provided at both ends for detachably fastening to the columns Ba of the building frame B. The support bar 2 supports not only the lower end but also the upper end of the ramp 1 by changing its direction. Cloth frame 3 with lifting hatch
Forms a rectangular frame 35 made of a pipe, forms an elevating hatch 31 at an intermediate portion thereof, and forms an insertion portion 32 through which the upper portion of the ramp 1 is inserted at one side of the elevating hatch. Locking part 33 to be detachably engaged
In addition, the lifting hatch 31 is equipped with a tread plate 34 made of an iron plate so that it can be opened and closed freely, and on both inside and outside of the tread plate 34, a notice such as "Close when opened" is given, and on both sides of the lifting hatch 31, The expanded metal 36 is stretched and colored in a conspicuous color, and furthermore, at both ends of the frame 35, the top horizontal bar Bb of the building frame B
The hook 37 is provided with an appropriate number of hooks 37 to be engaged. The lifting shaft partitioning handrail 4 is of a sickle lock type and has a plate 41 labeled "raising and lowering shaft" or the like. Curing wire mesh 5 with frame, upper and lower two on each floor (however, only one upper floor on the first floor)
Are removably attached to the support Ba of the building frame B, the frame 35 of the cloth frame 3 with the hatch, and the like by appropriate attaching means. Note that a series of upper and lower curing nets may be used instead of the framed curing wire net 5.

[0007]

According to the present invention, an elevating shaft can be formed by a cloth frame 3 with an elevating hatch on a narrow framed scaffold A, and a ramp 1 stably and firmly supported by a supporting bar 2 is supported on the elevating shaft. It can be equipped, and even if it is a narrow framed scaffold A, it can be equipped with elevating means. Of course, after elevating, the elevating hatch 31 is closed by the tread plate 34, so that this elevating shaft part also acts as a scaffold. It can be used without any problem, so even if only a narrow framed scaffold is used depending on the location conditions, it is possible to properly take up and down means without any problem, and because it can be provided at any place, There is no need to make a round trip to get up and down. Therefore, it is possible to safely perform the ascent / descent and work without a fall or the like, to improve the work efficiency, and to provide the structure and the manufacture simply and at low cost, which is extremely useful in practical use.
