Description

[Detailed Description of the Invention] The present invention relates to a suspended construction scaffold for work using hanging fittings protruding from the side wall of a structure such as large equipment.

Traditionally, when assembling large equipment, temporary scaffolding was erected around the equipment for work at heights, but in general, the work space around the equipment to be assembled and installed is kept to a minimum at the time of design. In addition, it was extremely difficult to assemble the temporary scaffold because the parts and tools of the assembly equipment were scattered around.

Furthermore, although the foundation work is generally completed at the time of assembly and installation of the equipment, the finishing work on the floor surface is incomplete and there are often grooves for wiring and piping on the floor surface, so that protective work on the floor surface is required in order to assemble the temporary scaffolding.

Furthermore, conventional assembled scaffolds have uneven shapes and are extremely bulky even in the disassembled state, requiring unstable storage conditions.Furthermore, they are made up of several types of assembly members, making it difficult to assemble them. Since the quantity of the parts varies depending on the shape, it is necessary to know the approximate shape of the assembled scaffold when transporting the necessary amount of assembled scaffolding, making inventory management and transportation extremely complicated.

The work of assembling and dismantling such assembled scaffolding in a small and complicated place as mentioned above requires an extremely large amount of cost and time, even though the scaffolding is a temporary structure that has no relation to the performance or quality of the construction. There were other drawbacks.

The present invention was made with the aim of simplifying the length and saving labor for the above-mentioned work, and the support arm 4 is rotated by inserting the support column 1 of the suspended type assembly scaffold into the hanging fitting (support body) 12 of the structure 21. The scaffolding board 20 is moved to be placed thereon, and when dismantled, the support arm is housed within the support column 1, so that it becomes a single prismatic column.

Hereinafter, the present invention will be described in detail based on one embodiment of the accompanying drawings.

FIG. 1 is a perspective view of an example of use in which the suspended scaffold is assembled. FIG. 2 shows details of a part of the support column 1 and the support arm 4 of the suspended type assembly scaffold, and shows the details of the support arm 4, which is made up of two flat plates 2 and spacer pieces 3 arranged at appropriate intervals. For example, the support arm 4 and its support member 5 are provided at a distance that does not pose a problem for a worker to stand on.

The support arm 4 is pivoted at one end so as to be rotatable between the plates of a support consisting of two flat plates, and the mounting pin 6 of the pivot portion is fitted into the support arm 4, The mounting hole 7 of the column that supports the mounting pin 6 is oval in the longitudinal direction of the column, and is supported at the upper end surface of the hole, so that when the support arm 4 is stored between two plates of the column, the support The arm is made to slide together with the mounting pin in the long diameter direction of the oval hole. Furthermore, by providing a protrusion 8 at the other end of the pivoting portion of the support arm 4 and cutting out a groove 9 inside the protrusion 8, the support arm 4 can be housed in the support column and mounted as described above. A spacer piece 3 is provided between the groove 9 and the two plates of the support by sliding in the oblong mounting hole together with the pin 6.
The upper end of the protrusion 8 provided on the support arm 4 is designed to prevent the support arm from easily rotating when the suspended assembled scaffold is dismantled, transported, and stored.
A hole 11 for inserting the protective fence 10 was bored.

Next, the suspended scaffold is attached to the support 1 of the structure 21.
Figure 3 shows the details of the part to be attached to 2 (hanging bracket).

Generally, a large structure 21 has a hanging fitting 12 for lifting and lowering the structure for transportation work. The present invention utilizes this hanging metal fitting 12 to suspend the support of the suspended type assembly scaffold thereon. As shown in FIG. 3, a spacer 13 suitable for the thickness of the hanging fitting 12 is seated with screws 14 or the like above the pillar made of two flat plates as described above. Because the thickness of hanging metal fittings differs depending on the structure, we prepared spacers of several different thicknesses so that they could be replaced with spacers that matched the thickness of the hanging metal fittings.

Next, attach the column with the spacer attached to the structure 21.
A slip-out prevention pin 1 is suspended from the hanging fittings 12 of
5 was inserted into the hole 15, and the distal end portion 17 of the removal prevention pin could be bent.

In addition, if the construction structure is very large and the work is carried out at high places, and the supports of the standard suspended scaffolding are not enough, use the connecting pieces 19 of the auxiliary supports 18 as shown in Fig. 2.
The structure is such that it can be joined together to form a long support.

Next, the assembly order of the suspended scaffold will be briefly explained. First, the above-mentioned pillar 1 is attached to the structure 21.
It is suspended from the hanging fitting 12, and the pin 15 for preventing removal is inserted and bent. Next, rotate the support arm 4 housed in the support column to the horizontal position, and
Place.

Next, the hole 11 in the protrusion provided at one end of the support arm
Insert the protective fence 10 into. This completes the assembly of the suspended scaffold.

As mentioned above, the suspended type assembly scaffold according to the present invention is used within the structure 21 and the hanging metal fittings (support body) 1.
2, the assembly work can be done very quickly and easily;
Since it can be installed completely regardless of the condition of the floor surface of the work place, there is no need to curing the floor surface, and there is no need to organize and remove construction equipment and tools scattered on the floor surface. In other words, it has become possible to use the small work space very effectively.
In addition, when the suspended scaffold is not in use, the support arm 4 can be stored in the support, so it has the shape of a single prismatic column.Furthermore, since aluminum is used in this embodiment, the weight is reduced, making it easier to transport and store. can now be performed extremely easily and stably, and safety and workability have been significantly improved.

Furthermore, even when stored in a warehouse or the like, since the shape is prismatic, it is possible to stack them in an extremely small space, resulting in the effect that the storage space is small.

Note that the use of the suspended scaffolding of the present invention is limited to cases where the construction structure has the support 12 (hanging fittings) as described above, so use of the suspended scaffolding of the present invention is not recommended at the time of designing the structure. If you consider the size and mounting position of the hanging fittings, the range of use will be further expanded and the effect will be increased.
