DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scaffold that can be easily moved on a deck.

[0002]

2. Description of the Related Art Conventionally, a deck plate obtained by corrugating a steel sheet into an uneven shape is used as a temporary floor material, and this deck plate is finally used as a formwork of a concrete slab. By the way, when performing the work of attaching the outer wall PC board in the construction work, in order to secure the necessary scaffolding, assembling the scaffolding on the deck plate using pipe material, or a rolling tower scaffold for a commercially available deck plate Is commonly used as a scaffold that can be moved on a deck plate.

[0003]

However, when assembling a scaffold necessary for the work of mounting the outer wall PC board on a deck plate by using a pipe material, concrete is cast on the deck plate. In the case of work, it becomes an obstacle. On the other hand, when performing PC adjustment or other finishing work after casting concrete, it is necessary to repeat the work, so that it has to be assembled many times. Because of this, the cost was forced to increase due to the work, and the work of assembling the scaffolds at high altitudes was dangerous, so there were many problems in terms of safety.

On the other hand, when a commercially available rolling tower scaffold for a deck plate is used, it is possible to temporarily move on the deck plate. However, when a caster provided on the leg falls into the deck groove, one person is moved. It is difficult to lift the deck plate, and the movement at the step of the deck plate is also difficult. As described above, in order to move the rolling tower scaffold for the deck plate on the deck plate, it is necessary to take care that the casters do not fit into the deck groove, but it is difficult for the worker to move such a scaffold alone. Movement at the deck plate step also requires the power of a large number of operators. Therefore, even when a commercially available rolling tower scaffold for a deck plate is used, there is a problem that it is difficult for an operator to move the scaffold alone on the deck plate.

[0005] It is an object of the present invention to provide a deck-moving scaffold that allows an operator to easily move alone on a deck plate.

[0006]

A feature of the present invention to solve the above-mentioned problem is that a sliding plate which can slide on a deck plate is provided below a frame leg of a frame scaffold assembled using steel pipes. On the point. The sliding plate is, for example, width 4
A square pipe having a height of about 20 mm and a length of about 0 mm can be bent and attached to a ski. In addition, this sliding plate,
Each of the two long members on which the two opposite frame legs are placed is bent upward at each end to form a ski plate,
A support member that is relatively short in a direction intersecting with each long member may be appropriately fixed to each long member.

According to this configuration, since each frame leg of the frame scaffold is mounted on the deck plate via the slide plate,
The framework scaffold can move on the deck plate by the relative sliding movement between the sliding plate and the deck plate.
As described above, since the movement of the framework scaffold on the deck plate utilizes the sliding between the slide plate provided under the frame legs and the deck plate, the dimensions and shape of the slide plate are adjusted to the uneven grooves of the deck plate. By selecting an appropriate shape and size that does not enter, the operator can easily move the framework scaffold alone in any direction on the deck plate.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a front view showing an embodiment of a mobile scaffold according to the present invention, and FIG. 2 is a right side view thereof. The moving scaffold 1 includes a frame scaffold 10 assembled using a pipe material, and a pair of sliding plates 30 provided at each lower end of the frame leg of the frame scaffold 10.
And consists of The frame scaffold 10 shown in FIG. 1 and FIG. 2 is composed of a building frame 11, 12, 13 and another building frame not visible in FIG. 1 and FIG.
5, 16 and two other cloth frames not visible in FIGS. 1 and 2 are fixed to the four building frames described above. An intersecting bracing 17 is provided between the pair of building frames 11 and 12, and the intersecting braces are similarly provided between the pair of building frames 13 and another building frame which is not visible in the drawing. A paddle (not shown) is provided.

[0009] Between the building frames 12 and 13, there are steps 18A-
18D are provided at appropriate regular intervals, whereby the ladder 1
8 are configured. A floor member 19 is laid on the same level as the cloth frames 15 and 16, and the worker can perform operations such as attaching an outer wall PC board on the floor member 19. Reference numeral 20 denotes a handrail for preventing a worker from falling down, reference numerals 21 and 22 denote chains for also preventing a worker from falling down, and reference numeral 23 denotes a movable scaffold 1 which is locked to beams and flanges on upper floors.
This is a catch clamp for stabilizing the surface.

[0010] Although an example of the configuration of the framework scaffold 10 has been described above, the configuration of the framework scaffold 10 is not limited to this, and it is needless to say that a known appropriate configuration can be adopted. In this case, it is preferable to use a small-diameter steel pipe in order to reduce the weight.

In order to enable the frame scaffold 10 to move in any direction on the deck plate 40, the frame 11, 12, 13 serving as the frame legs of the frame scaffold 10 and the lower end of another frame (not shown) are provided. Has a pair of sliding plates 30, 30
Is attached.

FIG. 3 shows one of the sliding plates 30 in an enlarged manner. In the present embodiment, the sliding plate 30 is formed by integrally forming a square pipe into a substantially K-shape. That is, the sliding plate 30 is disposed in the direction in which the building frames 12 and 13 are arranged (see FIG. 2).
And a long member 31 extending in a direction indicated by an arrow X in FIG. 3).
And support members 32 to 35 integrally fixed to the long member 31 so as to be orthogonal to the long member 31.
1 and the supporting members 32-35 are all made of square pipes. In the present embodiment, the support members 32 and 33 extend from the support point 12A of the building frame 12 on the long member 31 so as to be orthogonal to the long member 31, and the support members 34 and 35 Extends from the support point 13A of the building frame 13 at a right angle to the long member 31. The configuration of the other slide plate 30 is exactly the same as the configuration of the one slide plate 30 described above.

As can be seen from FIGS. 1 and 2, the long member 3
The two end portions 31A and 31B of the first scaffold 1 are bent in the shape of a ski so as to be gradually lifted away from the deck plate 40 toward the respective front ends, so that the moving scaffold 1 can be moved on the deck plate 40. When the longitudinal member 31 is moved in the longitudinal direction, it is possible to effectively prevent both ends of the long member 31 from being caught in the concave and convex grooves of the deck plate 40. On the other hand, the ends 32A to 35A of the support members 32 to 35 are similarly bent so as to gradually warp upward so as to gradually separate from the deck plate 40 toward the respective ends. Therefore,
When the moving scaffold 1 is moved on the deck plate 40 in a direction perpendicular to its longitudinal direction, it is ensured that the side edges 31C and 31D along the longitudinal direction of the long member 31 are caught in the concave and convex grooves of the deck plate 40. Can be prevented. As described above, the sliding plate 30 is configured to be able to slide on the deck plate 40 in any direction without being disturbed by the concave and convex grooves. Sliding motion can be ensured. When the moving scaffold 1 has been moved to a required position on the deck plate 40, the moving scaffold 1 can be fixed using the catch clamp 23 as in the conventional case.

As described above, an embodiment of the present invention has been described, but the present invention is not limited to this embodiment. For example, a configuration has been described in which two sets of the sliding plates 30 are provided commonly to a pair of building frames, but the present invention is not limited to this.
A sliding plate having the same configuration may be provided on each leg portion for each building frame. Further, the configuration using the square pipe as the material of the sliding plate 30 has been described. However, as the material of the sliding plate 30, a material in which a steel plate is formed into a ski plate shape in addition to the long member 31,
And can be used in place of the structure of the support members 32-35. The number of support members provided on the long member 31 may be arbitrary, and may be omitted as long as free sliding of the slide plate 30 on the deck plate 40 can be guaranteed. As such a form, it is conceivable that the width of the long member 31 is made relatively wider than the width of the concave and convex grooves, and both side edges are slightly bent upward.

[0015]

According to the present invention, as described above, the movable scaffold can be slid in any direction on the deck plate so as not to be caught by the concave and convex grooves, so that it is possible to move the human power and the operator can move the scaffold. Can move the moving scaffold alone. Therefore, once assembled, the scaffold can be moved to the end of the deck plate and used until the end, so that it is not necessary to disassemble the scaffold on the deck plate, and significant cost reduction can be expected.
