DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scaffold for a framework scaffold laid at a lower end portion of a framework scaffold.

[0002]

2. Description of the Related Art As shown in FIG. 8, a lower portion of a framework scaffold 10 used when constructing a building is fixed to a floor plate 11 in order to prevent slipping and sinking. Since the soleplate 11 is mostly made of wood, the base fitting 12 is fixed with nails 13.

[0003]

The wooden floorboards described above have the following disadvantages. Degrades quickly after repeated use. Since the degree of deterioration was difficult to judge from the appearance, the strength was uneasy. A large site was required for storage. It was expensive to always use a new floor. Deforestation could lead to destruction of nature.

[0004] The present invention has been made in view of such problems, and has as its objects the economics of repeated use, the safety of increased strength, and the elimination of the use of wood. An object of the present invention is to provide a scaffolding floorboard that is useful for environmental protection and the like.

[0005]

Means for solving the above problems are to provide a fixing frame to which a base metal of a framed scaffold is fixed on the upper surface of a steel plate, and to carry on the side of the plate. The fixing frame is provided with a movable side frame that fixes both sides of the base metal, a front frame that fixes the front part, and a removable stopper that prevents the base metal from shifting. It is characterized by becoming.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the scaffolding scaffold according to the present invention will be described below in detail with reference to the drawings. FIG. 1 shows an example in which a framed scaffolding flooring 1 is used,
The frame scaffolds 2 are laid at appropriate intervals so that a pair of base fittings 3 can be fixed.

The scaffolding scaffold 1 is a steel plate 4 of an appropriate length, and a pair of fixing frames 5 for fixing the base fitting 3 are provided on the upper surface thereof.

The fixed frame 5 includes an inverted L-shaped side frame 6 and a front frame 7.
And a stopper 8 protrudes from an insertion opening 5a into which the base fitting 3 is inserted. To attach the base fitting 3 to the fixing frame 5, as shown in FIG.
Stopped at

As described above, since the base member 3 is supported at both sides, the front portion, and the rear portion by the side frame 6, the front frame 7, and the stopper 8, respectively, the base metal 3 can be fixed to the fixed frame 5 without being nailed as in the related art. It is securely fixed just by inserting it. In addition, by connecting the fixed frames 5 with a connecting material or the like, the fixed frames 5 themselves can be fixed.

On the other hand, in order to remove the base metal fitting 3 from the fixing frame 5, it is possible to easily remove it by slightly lifting the rear part and pulling it backward as in the case where the base metal fitting 3 is attached.

A grip 9 is provided on a side surface of the plate 4 so that an operator can easily carry it.

FIG. 5 shows a structure in which one of the side frames 6 of the fixed frame 5 can be moved. The slide shaft 6a can be inserted into the elongated hole 4a of the plate body 4 and can be moved. Move according to the size of 3. In addition,
As shown in FIG. 6, not only one side frame 6 but also both side frames 6 can be moved to cope with a difference in installation width of the building frame. Note that this may be such that only one of them can be moved, not both.

FIG. 7 shows a structure in which the stopper 8 is bolted to be detachable, and is detached when attaching the base fitting 3 and screwed in after being attached.

[0014] A fixed frame for fixing a base metal of the framed scaffold is provided on the upper surface of the steel plate, and gripping portions are provided on a side surface of the plate for allowing the portable frame to be carried. The movable side frame for fixing the front part, the front frame for fixing the front part, and the removable stopper for preventing the base fitting from being displaced allow the operator to easily carry the apparatus and to use the apparatus easily.

[0015] Since the strength is increased and it can be used repeatedly, economy, safety and protection of the global environment can be achieved.

By making the side frame of the fixed frame movable, it is possible to change the size of the fixed frame corresponding to the base metal fitting, and to cope with a difference in the installation width of the building frame.

By making the stopper detachable, attachment and detachment of the base fitting can be easily performed.

When the base fitting is inserted into the fixed frame, the building frame can stand alone, and can be assembled by one person.

Since the base metal fitting is firmly fixed to the fixing frame, it is possible to omit rooting in the frame width direction.
