BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work floor used as a work scaffold for large coal boilers, powder storage bodies, and other large structures.

[0002]

2. Description of the Related Art Repair and remodeling of large-scale coal boilers, powder storage bodies, and other large-scale structures having recesses at the bottom,
Conventionally, the work floor required for painting and cleaning has a structure in which a steel pipe or wood is assembled by a skilled Tobi worker as shown in FIG. 12 and a structure in which an iron aggregate is assembled and used as shown in FIG. .

In all of these structures, members were carried inside the structure and were assembled and disassembled inside by a worker such as a Tobi job. Therefore, the work place is bad and the work is performed at a high place, which is dangerous and requires a lot of labor. In particular, when repairing coal boilers, etc., clinker and the like due to ash fall from the top, so the problem that workers who build the work floor faces their lives has always been a problem.

[0004]

The above-mentioned conventional work floor has the following problems to be solved.

That is, as described above, if the conventional work floor is, for example, a large structure, a member is brought into it,
There has been a problem that professional workers working in high places have to scaffold in a dangerous environment.

The present invention solves such a problem by
It is an object of the present invention to provide an assembling work floor which is easy to assemble and can be assembled into a required length (width) or can be quickly folded into a minimum unit size.

[0007]

Means for Solving the Problems The present invention is, as a means for solving the above problems, a truss body of a required unit which has a floor surface at one end and can be rotationally folded at a fulcrum, and a required number of the truss bodies mutually. concatenated with the fulcrum, the floor is tension truss of almost series of formable in the required units floor mutually mutually frettage
It is intended to provide a prefabricated work floor characterized by comprising a tensioning means .

[0008]

Since the present invention is constructed as described above, it has the following actions.

That is, a required number of truss bodies each having a floor surface at one end are continuously connected at a fulcrum, and each floor surface is
Since a series of floor surfaces can be formed and the work floor can be constructed by tensioning with the tensioning means , the truss body folded into the minimum unit size can be carried into a narrow space and deployed to set the tensioning means to the required value. A work floor can be formed simply by tensioning.

Further, if the work floor assembled in advance to a required length (width) is bent at a fulcrum in the center, and that portion is hung by a crane or the like and lowered to a required place in a large structure, it will be immediately Long working floor is obtained.

If the tensioning means is loosened, it can be easily folded around the fulcrum and quickly removed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS.

FIG. 1 is an explanatory view (cross-sectional view) showing a state in which the working floor of this embodiment is installed in a coal boiler furnace, and shows a cross section of the boiler. In the figure, reference numeral 1 is a work floor, 1a is a floor surface, 2 is a truss, 3 is a wire chord member, 4 is a wire brace member, 5 is an angle adjusting member for the furnace bottom, and 6 is a bending axis in the longitudinal direction. The work floor folded into a compact size is carried in through the work opening at the bottom of the boiler, and hung in the center of the furnace by a winch wire provided outside the furnace. Lower the work floor to a normal shape and lower it to the designated place.

FIG. 2 is a lateral view of FIG. 1, showing that the working floor 1 limited by the size of the carry-in port is mounted in the lateral direction, and the triangular floor is first mounted on the triangular floor material. The following shows the state where the materials are attached one after another. Reference numeral 7 is a joining member of the floor surface 1a and the truss, and with this point as a fulcrum, the floor surface 1a and the truss portion are superposed upon loading. Reference numeral 10 is a wire brace for stopping the floor surface 1a and the truss at a right angle position, and 9 is a fixing member for fixing the truss lower arc member of the floor material to be successively mounted, which is the final work with the working floor 1 mounted. .

Details of the work floor will be described with reference to FIGS. 3 to 10. FIG. 3 shows a side surface of the work floor. Wires 3 and 4 are wire chords and wire breaths made of wire, and when the work floor 1 is folded in the longitudinal direction from the center, since this member is a wire, it can be freely deformed and bent. When hanging and extending, this member acts as a chord and brace for pulling. 6
Is a folding member, and 5 is a length adjusting member with a length adjusting function (left and right screw turnbuckle) for securing a contact surface with the furnace bottom. FIG. 4 is a view showing a state in which the working floor 1 is folded in the length direction, and the longitudinal bending shaft 6 and the truss 2 are folded and stacked on the working floor 1. FIG. 5 shows a view of the work floor 1 folded in the longitudinal direction as seen from the floor side. FIG. 6 is a cross-sectional view taken along the line AA in FIG. 4, in which the joining member 7 serves as a fulcrum when the floor material and the truss material are folded and overlapped. FIG. 7 is a cross-sectional view taken along the line BB of FIG. 3 and shows the horizontal connection of the work floor 1. Figure 8 shows work floor 1
The horizontal flooring is shown and the adjacent work floors 1 are connected by the connecting member 8. FIG. 9 is an enlarged view of the fixing member 9 of FIG. 7, and is a fixing member (this is only one separate member) for fixing the trusses which will be the last at the end of the installation of the work floor 1.
Shows the state of installation. FIG. 10 is an enlarged view of the wire brace 10 of FIG. 7, and it should be understood that the floor material and the truss can be folded and folded by using the wire brace 10 that makes the floor material and the truss at right angles.

[0016]

Since the present invention is constructed as described above, it has the following effects.

That is, since the work floor and the truss supporting the floor can be folded and stacked with the joint portion as a fulcrum, and further can be folded and stacked in the length direction, a large work floor that can be mounted in a wide place can be made compact. Summary It is carried in as a product in the structure, inside the structure is lifted at the center, then both ends are lifted and the center part is lowered,
The folded parts can be returned to the original work floor for installation. This work achieves its purpose only by reversing the above procedure even when the work is to be removed, so that it has the effects of reducing dangerous work, shortening work time, and not requiring skill. Also, the present invention can provide a large floor without limitation to a structure requiring a large floor by only connecting.
