[0011] A temporary construction scaffolding unit 1 according to a first embodiment of the present invention will be described below with reference to Figures 1 to 5. In all the following drawings, the dimensions and proportions of each component may be shown as appropriate differently to facilitate understanding.

[0012] FIG. 1 is a side view of an installed temporary construction scaffolding unit 1 according to this embodiment. The temporary construction scaffolding unit 1 is broadly composed of a tower section 5 installed inside a building and a scaffolding section 10 connected to the tower section 5. FIG. 2 is a perspective view of the tower section 5, which has frames 5b, 5b1, and 5b2, and a base plate 5a. The tower section 5 is formed by assembling the frame 5b into a tower as shown in FIG. 2. A base plate 5a is provided on each of the four support pillars of the tower section 5, and four anchor bolts 7 are provided on the base plate 5a. The anchor bolts 7 are installed in a floor 50 of a building to secure the tower section 5 to the floor 50. As shown in FIG. 1, the scaffolding section 10 has running boards 10a1 to 10a4 and a frame 10b at different heights. In addition, stairs may be provided in the tower section 5 and the scaffolding section 10. In addition, the tower part 5 may be fixed to the floor 50 using a weight.

[0013] The tower section 5 is provided with a step pusher 5c1 and a step support 5c2 at any height position. The step pusher 5c1 and the step support 5c2 are flat-shaped. The step pusher 5c1 is provided on the frame 5b (extending diagonally) farther from the opening 51 of the building, and the scaffold support 5c2 is provided on the frame 5b (extending vertically) closer to the opening 51 of the building. The step pusher 5c1 and the step support 5c2 are configured to have different height positions due to the thickness of the steps 10a1, 10a2, and one end of the steps 10a1, 10a2 is pressed down by the step pusher 5c1. The height positions of the step pusher 5c1 and the step support 5c2 are configured to be freely changeable.

[0014] Steps 10a1 and 10a2 connected to tower section 5 protrude outside through the opening of the building. Steps 10a1 and 10a2 are connected by frame 10b. Above step 10a2, steps 10a3 and 10a4 are connected by frame 10b. Steps 10a1 to 10a4 are provided with staircase sections (not shown) to facilitate vertical movement of workers.

[0015] 3 is a schematic diagram of anchor positions of the temporary construction scaffolding unit 1 according to this embodiment. In this embodiment, only one support pillar of the tower section 5 is installed per square meter. Note that the tower section 5 may be configured so that only one support pillar is installed per area larger than one square meter, or may be configured so that only one support pillar is installed per area smaller than one square meter.

[0016] 4 shows an example of installation of the temporary construction scaffolding units 1 according to this embodiment. In this installation example, the temporary construction scaffolding units 1 are installed in positions facing the openings of a building, and the running boards 20 are laid across each temporary construction scaffolding unit 1 to install the scaffolding.

[0017] 5 shows an example of installation of a temporary construction scaffolding unit 1 according to this embodiment. In this installation example, the temporary construction scaffolding units 1 may or may not be installed in a position facing an opening in a building, and the scaffolding is installed by suspending a running board 20 across each temporary construction scaffolding unit 1. Furthermore, multiple temporary construction scaffolding units 1 are connected by connecting parts 9 made of metal, and in places where no temporary construction scaffolding units 1 are installed, these connecting parts 9 are fixed to the floor 50 with anchor bolts 7. Note that the intervals at which the temporary construction scaffolding units 1 and anchor bolts 7 are installed can be changed as appropriate.

[0018] The tower section 5 of the temporary construction scaffolding unit 1 according to this embodiment may be any three-dimensional shape, such as a cylindrical, rectangular column, cone, pyramid, etc. The anchor bolts 7 may be made of various materials such as adhesive or metal.

[0019] A temporary construction scaffolding unit 3 according to a second embodiment of the present invention will be described using Figure 6. In all of the following drawings, the dimensions and ratios of each component may be illustrated as appropriate to facilitate understanding. Note that the same components as those in the temporary construction scaffolding unit 1 according to the first embodiment may be designated by the same reference numerals, and their description may be omitted.

[0020] FIG. 6 is a side view of the temporary construction scaffolding unit 3 according to this embodiment in an installed state. The temporary construction scaffolding unit 3 is broadly composed of a tower section 5 installed inside a building and a scaffolding section 10 connected to the tower section 5. FIG. 2 is a perspective view of the tower section 5, which has frames 5b, 5b1, and 5b2, and a base plate 5a. The tower section 5 is formed by assembling the frame 5b into a tower as shown in FIG. 2. A base plate 5a is provided on each of the four support pillars of the tower section 5, and four anchor bolts 7 are provided on the base plate 5a. The anchor bolts 7 are installed in the floor 50 of the building to secure the tower section 5 to the floor 50. As shown in FIG. 6, the scaffolding section 10 has running boards 10a1, 10a2, 10a31, and 10a41 at different heights and a frame 10b1. In the temporary construction scaffolding unit 3 of this embodiment, the frame 10b1 of the scaffolding section 10 is not provided on the building side. Therefore, the temporary construction scaffolding unit 3 of this embodiment can be made lighter than the temporary construction scaffolding unit 1 of the above-mentioned embodiment. Furthermore, stairs may be provided on the tower section 5 and the scaffolding section 10, respectively. Furthermore, the tower section 5 may be fixed to the floor 50 using a weight.

[0021] The temporary construction scaffolding units 1, 3 according to the embodiments of the present invention and the scaffolding installation method using the same provide the following effects. (a) Since the temporary construction scaffolding units 1 and 3 are set up within the floor, the number of work processes within the floor during scaffolding installation work can be increased, thereby reducing work time at heights (outside) and ensuring safety. (i) The height position of the step connected to the tower section 5 can be changed as desired, making it possible to adapt to a variety of work sites. (c) Since scaffolding only needs to be set up on the necessary floors, the time required to assemble the scaffolding can be shortened, the amount of scaffolding materials used can be reduced, and the cost of transporting the scaffolding materials can be reduced. (e) When carrying out pinpoint construction work on the exterior of a building, it is possible to significantly reduce the cost of assembling scaffolding.

[0022] The above-described embodiment is a preferred example of the present invention, and various technically preferable limitations are applied thereto, but the scope of the present invention is not unduly limited by the above description. Furthermore, not all of the configurations described in the above-described embodiment are essential components of the present invention. Furthermore, the configurations described in the above-described embodiment may be added to or combined with each other. [Industrial Applicability]

[0023] The present invention can also be widely used in temporary construction scaffolding and methods for installing temporary construction scaffolding. [Explanation of symbols]
