Description

[Detailed Description of the Invention] <<Industrial Application Field>> The present invention relates to a method for transporting repurposed formwork materials, etc., and a bracket scaffold used therein, and more specifically,
Regarding the method of transporting formwork, etc. used for concrete pouring on the lower floor when reusing (repurposing) it on the upper floor in the construction of a multi-story building, and the bracket scaffolding used therein. It is something.

<<Prior Art>> In the construction of a multi-story building, formwork materials and the like used on the lower floors during frame construction etc. are usually reused as formwork materials, etc. on the upper floors. For this purpose, it is necessary to transport the formwork materials used on the lower floors to the upper floors, and the following methods have been conventionally used for this purpose.

For example, as shown in FIG. 5, a temporary opening 4 is provided in the building floor 2, and formwork materials 10 used on the lower floor 8 are lifted and transported to the upper floor 12 by a crane or the like 6 through the temporary opening 4. was.

For example, as shown in FIG. 6a, a temporary scaffolding 14 is erected from the ground to the lower floor 8, and the formwork materials 10 used on the lower floor 8 are once transported to the temporary scaffolding 14, and from there, a crane or the like 6 is used to raise the upper floor. Floor 12
The formwork materials, etc. 10 were being lifted and transported. As shown in Figure b, when an external scaffolding 16 is present on the outside of the building for frame work etc., a temporary scaffolding 14 is installed outside the external scaffolding 16 to transport the repurposed formwork materials 10. I was doing it.

<<Problems to be Solved by the Invention>> However, in the method of providing the temporary opening 4 in the floor of the building shown in FIG. The construction work cannot be carried out until the temporary opening 4 is closed, and the provision of the temporary opening requires extra cost and effort.

In addition, in the method of installing temporary scaffolding shown in Figure 6 a and b, new materials must be procured to install the temporary scaffolding, and the amount of materials increases as the hierarchy gets higher. Providing temporary scaffolding requires a great deal of cost and effort, as it takes a long time and a large number of people to assemble and disassemble the scaffolding.

This invention was made in view of these problems, and its purpose is to provide a method for transporting formwork materials used on lower floors to upper floors with little cost and effort, and to provide a method for transporting formwork materials, etc. used on lower floors to upper floors with little cost and effort. There are brackets to provide scaffolding.

<Means for Solving the Problems> In order to achieve the above object, the method for transporting repurposed formwork materials, etc. according to the present invention includes preparing a bracket scaffold that can be suspended in a wall opening or an external scaffold, and Suspend the bracket scaffolding by a crane or the like to a wall opening or external scaffolding on the floor where formwork materials, etc. are carried out,
The formwork, etc. on the carry-out floor is moved to the bracket scaffolding, and the formwork, etc., transferred to the bracket scaffolding is lifted and transported to the carry-in floor of the formwork, etc. by a crane, etc., and then the bracket scaffold is moved by a crane, etc. The formwork materials and the like for each floor are sequentially transported from the lower floor to the upper floor by hoisting it up and suspending it from a wall opening or external scaffolding on the floor immediately above, and repeating the above operation.

Furthermore, the bracket scaffold used in the method for transporting repurposed formwork materials, etc. according to the present invention has a working floor surface on which the formwork materials, etc. and workers are placed, and a support surface substantially perpendicular to the working floor surface. The upper part of the support surface is provided with means for locking to the wall opening or external scaffolding, and the lower part is provided with means for locking or abutting against the wall or external scaffolding, and the support surface is lifted by a crane or the like to reach the desired floor. This allows it to be suspended in a wall opening or on external scaffolding.

≪Operation≫ Horizontal and vertical forces generated at this position are supported by means of locking to the wall opening or external scaffold provided at the upper part of the support surface substantially perpendicular to the work floor, and The bracket scaffold is suspended in the wall opening or the external scaffolding because the horizontal and vertical forces or horizontal forces occurring at that location are supported by means of locking or abutting the wall surface or the external scaffolding.

In this suspended state, the work floor of the bracket and the unloading floor for formwork materials, etc. are approximately on the same level, so the formwork materials, etc. are carried out to the work floor of the bracket, and from there, the formwork materials, etc. are removed using a crane, etc. Transport to the upper floor. The bracket is then hoisted up by a crane or the like and suspended from a wall opening on the upper floor or an external scaffold. By repeating these operations, formwork materials and the like are efficiently moved from the lower floors to the upper floors and repurposed.

<<Embodiment>> FIG. 1 is a diagram showing an embodiment of a bracket scaffold according to the present invention suspended in a wall opening 30. The framework of this bracket scaffold 20 is formed by combining steel pipes. The surface 24 of the bracket scaffolding, which is approximately at the same level as the floor 22 of the suspended building, is temporarily placed with repurposed formwork materials, etc.
It also serves as a work floor for workers to work on, and is covered with board materials 26. A support surface 28 extending along the wall surface of the building perpendicularly to the working floor 24 has a locking means 32 to the wall opening 30 at the upper part and a contact means 36 to the wall surface 34 at the lower part. There are two locations on the left and right. The locking means 32 locks onto the wall opening 30 by inserting a vertical groove formed between the steel pipe 32 processed into an inverted L shape and the support surface 28 into the lower wall surface 38 of the wall opening 30 from above. This is done by fitting. In this bracket scaffold 20, no special measures are taken for the abutting means 36. The contact of the support surface 28 with the lower wall surface 34 is caused by the fact that the scaffold bracket 20 tends to rotate clockwise in FIG. 1A around the locking means 32 due to its weight. The lower part, that is, the lower part of the steel pipe constituting the support surface 28 is the wall surface 3
This can be done automatically by measuring the length of the steel pipe so that it corresponds to 4. The bracket scaffold 20 is suspended in the wall opening because the locking means 32 supports the horizontal and vertical forces occurring at the position, and the abutment means 36 supports the horizontal force occurring at the position. Note that handrails 40 are provided around the work floor 24 in consideration of work safety.

In order to transport formwork materials etc. using the bracket scaffolding 20 according to the present invention, as shown in FIG. Floor formwork materials, etc. 4
2 is carried to the bracket scaffolding 20, and from there, the formwork material etc. 42 is lifted and transported to the carry-in floor 46 by a crane etc. 44. Next, when carrying out the formwork etc. on the floor 48 immediately above, as shown in FIG. After that, formwork materials, etc. are transported in the same manner as described above.

FIG. 3 is a diagram showing an embodiment of a bracket scaffold according to the present invention suspended from an external scaffold 54. At the upper part of the support surface 52 perpendicular to the work floor 50, there are locking means 56 for the external scaffolding 54, and at the lower part there are locking means 56 for the external scaffolding 54, all at three locations: left, middle, and right. It is provided. Both locking means 56 and 58 are fixed clamps. The bracket scaffold 60 is configured such that a fixed clamp 56 at the top of the support surface 52 supports horizontal and vertical forces occurring at that location, and a fixed clamp 58 at the bottom of the support surface 52 supports horizontal and vertical forces occurring at that location. Therefore, it is latched to the external scaffolding 54 in a suspended state. Method of transporting formwork materials etc. using bracket scaffolding 60, bracket scaffolding 6
The method of moving 0 to another floor is the same as that of the bracket scaffold 20 attached to a wall opening, and will therefore be omitted. Note that explanatory diagrams thereof are shown in FIGS. 4a and 4b.

<<Effects of the Invention>> The present invention involves transporting the formwork materials by suspending the bracket scaffolding on a floor for transporting the formwork materials, etc., and then moving the bracket scaffolding to the upper floor and performing the above-mentioned transportation work again. Since this process is repeated repeatedly, it is not necessary to create a temporary opening and close it.
Further, since there is no need to specially provide a framework scaffold for reusing the formwork, a large amount of cost is not required.

In addition, in order to suspend the bracket scaffold according to the present invention on a floor for discharging formwork materials, etc., the bracket scaffold is hoisted to a predetermined floor using a crane or the like, and at that position, the bracket scaffold is placed on a support surface substantially orthogonal to the work floor. locking means,
Locking to wall openings or external scaffolding by abutment means,
Since it is only necessary to make contact, it does not require a lot of time or a large number of people to install the bracket scaffold. Furthermore, since the present invention suspends the bracket scaffolding on the floor for carrying out formwork materials, etc., it can be installed even in places where temporary scaffolding etc. cannot be installed from the ground.
