Abstract

(57) [Summary] (Modifications required) [Problem] When transporting or storing, stacking conventional box-shaped scaffolds creates space between the upper and lower scaffolds, increasing the volume and taking up space. Also, a gap was formed at the joint of the scaffold plate during assembly, and work on this was dangerous. A flat metal plate or the like serving as a scaffold plate is bent by a press machine so that its cross section becomes a corrugated plate, thereby reducing the number of processing steps in a factory, reducing the strength of the scaffold plate and reducing the manufacturing cost. . When using a press scaffold, support pipe 1
A scaffold plate having a corrugated cross section is placed on top of 0, and the next scaffold plate is placed on the end of the scaffold plate, and the fixing clip 6 is inserted into the pinch hole 12 of the overlapping scaffold plate, and fixed to the scaffold support pipe thereunder. I do. Repeat this to extend the scaffold and assemble. An integrated scaffold plate having a fixture at the end of the other press scaffold plate is attached to the support pipe by rotating the fixture by 90 degrees.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[Industrial applications] At construction and civil engineering work sites, in the case of civil engineering work, such as around the frame of a building or wall construction, temporary construction scaffolds such as vitality are assembled on a scaffold plate to work at heights. I do.

[0002]

2. Description of the Related Art A conventional scaffold plate of a bite scaffold is formed by bending an end of an upper surface serving as a tread plate at a right angle, and attaching a square pipe to the back surface of the tread plate to increase strength as a unit.
Hook on 0 and fix. This scaffold plate is connected horizontally along the work surface to support the weight of the worker on the scaffold plate. However, since the scaffold plate is hooked on the support pipe 10 and fixed with metal fittings, a gap is formed at the joint of the scaffold plate. Can be.

[0003]

In the case of stacking scaffolding plates one on top of the other to eliminate gaps at the joints of the connecting portions of the scaffolding plates, and by corrugating the cross section, to increase strength and to carry or store In addition, the space when stacked is reduced, and the overall volume can be reduced. Also, we want to reduce the manufacturing cost of the scaffold.

[0004]

Means for Solving the Problems A single iron plate having a thickness and a length suitable for a frame such as a bite scaffold is pressed, but the width of the tread plate 1 of the scaffold plate 5 is wide so that it can be easily walked. The valley bottom 2 is made narrower to withstand the weight of the worker. That is, the cross section was bent into a corrugated shape in order to increase the strength of the scaffold plate 5. When the scaffold plate 5 is set on the support pipe 10, a reinforcing strip 11 is attached to a portion of the valley bottom 2 that comes into contact with the support pipe 10 and the scaffold board 5, and fixed projections 3 are provided on both ends of the width end of the strip. At the same time, a reinforcing strip 11 is attached to the back surface of the tread plate 1 at a portion other than the portion in contact with the support pipe 10 to increase the strength. In order to fix to a support pipe 10 which is a framework of a scaffold, a sandwiching hole 12 is provided in a valley bottom 2 of a groove 4 of a scaffold plate 5,
The fixing clip 6 is inserted there and fixed to the support pipe 10.
The groove 4 of the tread plate 1 is formed as a groove 4 of a scaffold plate 5 that is small enough to allow the thumb and the forefinger to enter, so that it is easy to walk.
In the portion where the support pipe 10 hits, two pinching holes 12 are formed across the support pipe 10 so that the fixing pinch 6 can pinch and fix the support pipe 10 there. As for the pinching holes 12 of the scaffold plate 5, two pinching holes 12 are formed at the four corners of the corrugated scaffold plate 5 at a total of eight places. In addition, the fixing pinch 6 of the integrated scaffold plate 5 having the fixing metal 15 attached to the scaffold plate 5
The upper part is pinched by a finger around the fulcrum pin 9, and the lower part is sandwiched between the support pipes 10 through the sandwiching holes 12 in the valley bottom 2 of the scaffold plate 5. The fixing pinch can be opened and closed with two fingers with a finger 7 so that two semicircular members of the same shape face each other like a circular scissor with a fulcrum pin 9, and the fulcrum pin hole 8 is an ellipse. When it is formed into a shape and is passed through the sandwiching hole 12 of the scaffold plate 5, the width of the fixed sandwich 6 can be adjusted to facilitate passing.

In the scaffold plate 5 on which the fixing bracket 15 in which the scaffold plate 5 and the fixing bracket 15 are integrated rotates, a moving hole 14 is formed at each end of the tread plate 1, and a T-shaped projection 17 of the fixing bracket 15 is set in the hole. In order to allow the fixing bracket 15 to rotate, a moving hole 14 is opened outward from the middle valley bottom 2 of the tread plate 1 at both ends to the rising brim, so that the fixing bracket 15 can rotate 90 degrees about the T-shaped projection 17 as an axis. When the slide 16 is lowered, it does not come off the support pipe 10.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
When the reinforcing strip 11 with the fixing projections 3 on the valley bottom 2 of the scaffolding board 5 is set so as to ride on the scaffolding board 5,
The fixed pinch 6 is inserted into the two pinch holes 12 which overlap with each other so that the pinch holes 12 of the upper scaffold plate 5 ′ match the pinch holes 12 of the lower scaffold plate 5. When the handle 7 of the fixed pinch 6 is closed, the tip of the circular pinch is opened, and two scaffold plate holes 12 at the valley bottom 2 of the narrow groove 4 where two scaffold plates 5 are overlapped.
Then, when the fixing pinch 6 is made to penetrate, the scaffold plate 5 is closed naturally by the weight of the circular pinching under the support pipe 10 of the vital scaffold. By repeating this work, the scaffold plate 5
Are long and horizontally connected to form a scaffold for buildings and retaining walls.
When disassembling, use the fulcrum pin 9 of the open fixed pinch 6
Close the two handles 7 tied together with the thumb and forefinger. Then, the tip of the circular fixed clip 6 can be opened and pulled upward, and the fixed clip 6 can be removed from the support pipe 10 of the scaffold. Further, the scaffold plate 5 ′ and the scaffold plate 5 that have overlapped on the pipe 10 can be removed.

[0007] The fixing bracket 15 in which the scaffold plate 5 and the fixing bracket 15 are directly attached to the end of the tread plate 1 is used for transportation and storage.
Therefore, the fixing metal 15 is rotated 90 degrees in the horizontal direction to reduce the gap between the scaffold plates 5 when the scaffold plates 5 are stacked.

[Effects of the Invention] The conventional scaffold is assembled by hooking the inverted U-shaped hooks protruding from both ends of the scaffold plate on the support pipe 10 of the bite scaffold.
There was a gap in the seam, but this scaffold had no gap because the adjacent scaffolding plates overlapped, and to eliminate the step due to the thickness when the scaffolding plates 5 and 5 'were stacked, Since the scaffold plate 5 is provided with a corrugated plate, the space is small and the volume is small, so that it is convenient for transportation and storage.
