Description

[Detailed Description of the Invention] (Industrial field of application) This utility model is a frame scaffolding or a simple scaffolding mobile scaffolding used for light work shelf scaffolding, and a steel scaffolding board for the work floor It relates to the horizontal material used as joists when doing.

(Prior Art) Conventionally, as a horizontal member of this type, there is known a cloth frame for a frame scaffold in which a cloth material having attachment portions at both ends is framed with arm wood.

(Problems to be solved by the invention) Conventionally, as a shelf scaffold for light work used for ceiling construction, etc., there is a construction method in which scaffold plates are laid side by side in a bootstrap-like manner on a horizontal material as joists. It is common.

In this case, the hanging allowance for the fabric material at the very end of the scaffolding plate is legally set to 10 to prevent the fabric material from falling off.
cm and above.

The distance between adjacent scaffolding plates is 30 cm or less in order to prevent workers from falling.

However, these dimensions are conventionally left to the sense of each worker who constructs a shelf scaffold, without accurately measuring and arranging the hanging allowance and spacing of each scaffolding board,
No precautionary measures were taken against accidents, other than fixing with a safety rubber band.

Further, when connecting the scaffold plates in the longitudinal direction, it is usual that the extreme ends of the scaffold plates are overlapped on the fabric material, and there is a risk that the upper and lower scaffold plates may shift in the lateral direction and fall.

In addition, connect the pedestal trolleys of the simple assembly type mobile scaffold in series with a cloth material, and if you cross the scaffolding board with the cloth materials of other pedestal trolleys installed in parallel, use a cloth material. The work efficiency was poor because the scaffolding boards were laid out without gaps because they were connected to the cloth material by horizontal braces.

The present invention has been made in view of the above problems of the conventional technology, and the purpose thereof is to make a steel scaffolding plate erected in a booth-returning manner as a shelf scaffold to shift in the lateral direction. It also prevents the extreme end in the longitudinal direction from slipping off from the fabric material and falling off, and in the case of a simple assembly type moving scaffolding, the number of steel scaffolding plates used for the work floor can be small. It is intended to provide horizontal materials as.

(Means for Solving the Problem) In the present invention, in a cloth material having attachment parts at both ends of the cloth material, two spacers are used as one pair, and the outer dimensions of the steel scaffold plate are installed on both sides. The size is close to the inner edge of the cloth material, and the two pairs of the spacers are the width of the steel scaffolding plate 24 cm.
The problem is solved by mounting it upwards at an inner spacing larger than (30 + 2a) cm.

a is the width of the cloth material of the steel scaffolding board.

(Operation) A pair of spacers, which are a pair of steel scaffolding plates used for the work floor, are laid across the fabric material so that the spacers are provided between the fabric materials on both sides of the steel scaffolding plate, thereby constructing the shelf scaffolding. .

In that case, the shift in the lateral direction of the steel scaffolding plate is limited to the difference between the inner size of the cloth material on both sides of the steel scaffolding plate and the outer size of the pair of internally provided spacers.

The inner dimension of the pair of spacers that are adjacent to each other is (30+
2a) If it is allocated to cm or less, the open dimension of adjacent steel scaffolding boards will be 30 cm or less.

In this case, since the steel scaffolding plate is laid across as a passage, it is preferable to evenly allocate the opening dimensions.

Further, since the spacer attached to the fabric material is arranged inside the beam material at the extreme end portion of the steel scaffold plate, the extreme end portion of the steel scaffold plate is prevented from falling off from the fabric material.

In the case of a simple assembly-type mobile scaffolding, the pair of spacers and the cloth material of the steel scaffolding plate work via the pedestal trolley parts with the connecting material provided between the pedestal trolley parts arranged in parallel, Bears the plane stress of the floor.

To explain this action in detail, when a pair of spacers provided on two cloth materials arranged in parallel, which are provided between two pedestal carriages arranged in series, are diagonally opposed to each other.
