Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a step stool device that is used at a low cost when working at a high height in an assembly factory or the like.

(Prior Art) Conventionally, as shown in the first diagram, a concrete-covered channel frame a is used as a device of this type.
There are known types in which a steel plate with slips c is applied to a channel frame a as shown in the second figure.

(Problems that the invention aims to solve) However, such products have relatively high production costs, lack versatility, or when not in use.
This involves inconveniences such as time-consuming disposal.

(Means for solving the problem) The purpose of the present invention is to obtain a device that does not have such inconveniences, especially a device that is low in production cost and easy to dispose of when not in use. A pair of left and right side plates elongated in the front and back direction are installed on both left and right sides of a generally rectangular group of blocks arranged side by side in a plurality of blocks on the front, rear, left and right sides, respectively. The two side plates are brought into contact with each other so as to project rearward, and the front and rear ends of both side plates are connected in the lateral direction via longitudinal rods.

(Example) An example of implementing the present invention will be explained with reference to attached drawings.

Figures 3 to 5 show an example of this. Reference numeral 1 indicates a concrete block with a rough and flat surface. A plurality of blocks 1 are arranged in front, rear, left, and right to form a substantially rectangular block group 3 having a predetermined size as a whole. In this case, the above-mentioned U grooves 2 are connected to each of the left and right side surfaces to form a long U groove row 4 as a whole.

On both left and right sides of the block group 3, side plates 5, 5, such as C-shaped lightweight channel ropes extending longitudinally in the front and back direction, are attached approximately along each U-groove 4. The front and rear sides of each side are brought into contact with each other so as to protrude, and then both side plates 5, 5 are connected to each other at each of the front and rear ends with round steel rods or other rods 6 extending longitudinally in the transverse direction. . Generally, the rod 6 has a spiral formed at its tip in advance and a nut 6a attached thereto, and each side plate 5 has a through hole 7 formed at its front and rear ends in advance, into which the rod 6 is inserted. However, it is common.

(Function) To make this, first make concrete block 1.
A plurality of blocks are arranged and prepared in a block group 3 of a predetermined size, and then side plates 5, 5 are brought into contact with both outer sides of the block group 3, and the side plates 5, 5 are attached to each rod 6 before and after the block group 3.
If they are tightened together, the whole can be integrated and used as is.At this time, if each side plate 5 is aligned within each U-groove row 4, there will be no misalignment, and the manufacturing cost can be reduced. 1/5 to 1/8 of the conventional one is sufficient, and then, when not in use, it is sufficient to unfasten each rod 6, remove each side plate 5, and disassemble the block group.

(Effects of the invention) In this way, according to the invention, a plurality of concrete blocks are assembled together and bound together by the side plates on both sides and the rods in front and behind them, so that they can be assembled into a single piece. It can be easily and inexpensively obtained with dimensions of , and its dimensions can be easily changed, and furthermore, when not in use, it can be easily disassembled and disposed of.
