Description

[Detailed description of the invention] This invention relates to a slope that is attached to the end of a scaffold board.

When scaffolding boards used for various construction works are laid one after another, the ends are stacked by an appropriate amount.

For this reason, on the upper surface of a group of scaffolding boards that have been successively laid down, there is a step equal to the thickness of the upper scaffolding board at the end, and there is a risk that a worker may trip over this step.

This idea was made in order to prevent the above-mentioned dangers, and the aim is to provide a slope that can eliminate the level difference that occurs at the end of the scaffolding board and improve safety when using the scaffolding board. It is a purpose.

The structure of this device is to attach a cap to the end of a single scaffold board that has a bent groove for reinforcement along the longitudinal direction of the upper wall, and fit the cap along the width direction. It is a slope, and the sloped top plate and the side plates provided opposite to each other on both sides of the top plate form an external fitting part for the cap of the scaffolding board at the end of the sloped upward side of the top plate, and the sloped upward side of the top plate A hook is provided at the end of the scaffold board to engage with the upper edge of the cap at the bent groove part of the scaffold board, and a hook is provided at a position near the end of the sloped up side of both sides of the board, and a hook is attached to the vertical part and from the upper end of this vertical part in the slope downward direction. An inverted L-shaped elongated hole consisting of a horizontal portion toward each other is provided, and a hanging shaft that is movable along the shape of the elongated hole is horizontally mounted between the elongated holes on both sides, and the elongated hole is such that the hook is connected to the cap. The position is set so that the locking shaft located between the lower ends of the vertical portion comes into contact with the end surface of the cap when engaged with the cap.

This invention will be explained below based on the embodiments shown in the accompanying drawings.

As shown in the figure, the slope 2 connected to the end of the scaffolding board 1 is connected to an inclined top plate 3 and approximately triangular side plates 4, 4 provided on both sides of the top plate 3 so as to be bent downward.
The cross section along the width direction is formed in a downward U-shape.

As shown in FIG. 1, the scaffolding board 1 is made by connecting two single scaffolding boards 8, 8 side by side and having a side wall 6 on both sides of an upper wall 5 and a lower wall 7 on the lower edge of this side wall 6, and connecting both ends. It shows a steel scaffolding board with a cap 9 fitted on it.
The upper wall 5 is provided with a slip stopper 10 and a reinforcing bent groove 11.

The width of the top plate 3 of the slope 2 is cap 9.
It has a width equal to or wider than the full length of the slipper, and has a slip stopper 12 on its upper surface, and has horizontal portions 13 and 14 at both ends. forms an external fitting part 15 that fits into the end of the scaffolding board 1 by falling in from above.

Therefore, the slope 2 is placed on the lower scaffolding board 1a in the upper and lower overlapping parts of the scaffolding boards 1 and 1a,
When the external fitting part 15 is externally fitted to the end of the upper scaffold board 1,
As shown in FIG. 3, the inclined top plate 3 covers the step at the end of the upper scaffolding board 1 at a gentle inclination angle.

The slope 2 is provided with a coupling mechanism with the upper scaffold board 1, so that it can be connected and integrated with the upper scaffold board 1.

A first example of the coupling structure shown in FIGS. 1 to 3 is a hook 16 that is fixed to the upper horizontal part 13 of the inclined top plate 3 through the bent groove 11 and engages with the upper edge of the cap 9, and A hanging shaft 18 is horizontally suspended between two oblique L-shaped long holes 17 provided at positions corresponding to numbers 4 and 4.

The above-mentioned latching shaft 18 is movable along the elongated hole 17, and by selecting the position of this latching shaft 18,
The slope 2 can be attached to and detached from the upper scaffold board 1.

As shown in Figs. 1 and 2, the latching shaft 18 is
When the external fitting part 15 is externally fitted to the end of the upper scaffold board 1 in a state where it is located in the horizontal part 17a of 7,
The hook 16 is located inside the inner edge of the cap 9, and when the slope 2 is moved in the direction of arrow A in FIG. 3 in this state, the hook 16 engages with the cap 9.

After this, the hanging shaft 18 is attached to the vertical part 17b of the elongated hole 17.
As shown in Figure 3, hook 1
6 and the hanging shaft 18 firmly hold the cap 9, and the scaffolding board 1
In contrast, the slope 2 is completely fixed.

Further, when removing the slope 2 from the scaffold board 1, the hook 16 can be removed from the cap 9 by moving the hook shaft 18 to the horizontal portion 17a, contrary to the above.

Next, a second example of the coupling mechanism shown in FIG. is forming.

A third example of the coupling mechanism shown in FIGS. 5 and 6 is
A cut combining two L-shapes is made in the horizontal part 13 of the top plate 3, and the part surrounded by the cut is bent downward at right angles to form an L-shaped hook 16.

In addition, the scaffolding board 1 is not set as two scaffolding boards 8, 8 arranged side by side, but may be formed entirely of one piece or a wooden scaffolding board. In the case of boards, screws are used as the connection mechanism, and if the width of the slope 2 is widened, it can be used simultaneously for two scaffold boards 1 installed side by side.

The slope of this invention has the above-mentioned configuration, and the slope 2 is connected to the end of the upper scaffold board 1 when the scaffold board is laid between the horizontal scaffolding bars 21.

As shown in FIGS. 3 and 4, the slope 2 is constructed by covering the difference in level at the end of the upper scaffolding board 1 with a sloped top board 3, and smoothing the upper surface at the overlapping part of the upper and lower scaffolding boards 1 and 1a. This prevents tripping.

As described above, according to this invention, a slope is formed by providing an external fitting part to the end of the scaffolding board at the end of the inclined upward side of the inclined top plate, and a coupling mechanism with the scaffolding board is provided on this slope. , the difference in level that occurs at the end of the scaffolding board when it is used can be covered with a sloped top plate, the difference in level on the walking surface on the scaffolding board can be eliminated, and the safety on the scaffolding board can be greatly improved. There is.

In addition, the slope is provided with a hook that engages with the cap of the scaffold board at the end of the sloped top plate on the upward slope, and along this L-shaped long hole between the inclined L-shaped long holes provided on each side wall. Since we installed a movable locking shaft, if the hook is engaged with the cap and the locking shaft is positioned at the vertical lower end of the L-shaped long hole, the locking shaft will come into contact with the cap and the scaffolding The slope can be completely fixed to the board, and the slope does not move, improving walking safety.
By moving the hanging shaft along the elongated hole, it can be easily removed from the scaffold board.
