A temporary construction scaffolding unit 1 according to a first embodiment of the present invention will be described below with reference to FIGS. 1 to 5. FIG. In addition, in all the drawings below, in order to facilitate understanding, there are cases where the dimensions and ratios of the components are changed as appropriate.

FIG. 1 is a side view of an installed state of a temporary construction scaffolding unit 1 according to this embodiment. The temporary construction scaffolding unit 1 is roughly divided into a scaffolding section 10 connected to a scaffolding section 5 provided inside a building and connected to the scaffolding section 5 . FIG. 2 is a perspective view of the tower 5 having frames 5b, 5b1, 5b2 and a base plate 5a. The yagura portion 5 is constructed by assembling a frame 5b into a yagura as shown in FIG. A base plate 5a is provided on each of the four columns of the tower portion 5, and four anchor bolts 7 are provided on the base plate 5a. The tower part 5 is fixed to the floor 50 by installing the anchor bolts 7 on the floor 50 of the building. As shown in FIG. 1, the scaffold section 10 has footboards 10a1 to 10a4 and a frame 10b having different height positions. In addition, the tower section 5 and the scaffolding section 10 may each be provided with stairs. It should be noted that the tower section 5 may be fixed to the floor 50 using a weight.

A footboard pressing portion 5c1 and a footboard supporting portion 5c2 are provided at arbitrary height positions on the turret portion 5. As shown in FIG. The footboard pressing portion 5c1 and the footboard supporting portion 5c2 are flat plate-shaped. The footboard pressing portion 5c1 is provided on the frame 5b farther from the opening 51 of the building (stretching in the oblique direction), and the scaffolding support portion 5c2 is provided on the frame 5b closer to the opening 51 of the building (extending in the vertical direction). be done. The tread pressing portion 5c1 and the tread supporting portion 5c2 have different height positions by the thickness of the treads 10a1 and 10a2, and one end of the treads 10a1 and 10a2 is pressed by the tread pressing portion 5c1. The height positions of the footboard pressing portion 5c1 and the footboard supporting portion 5c2 can be changed arbitrarily.

The footboards 10a1 and 10a2 connected to the tower 5 are protruded outside from the opening of the building. The footboards 10a1 and 10a2 are connected by a frame 10b. Further, footboards 10a3 and 10a4 are connected above the footboard 10a2 by a frame 10b. By providing a step portion (not shown) on the footboards 10a1 to 10a4, the operator can easily move up and down.

FIG. 3 is a schematic diagram of the anchor positions of the temporary construction scaffolding unit 1 according to this embodiment. In this embodiment, the structure is such that only one post of the tower portion 5 is installed per square meter. In addition, the structure in which only one support|pillar is installed per area larger than 1 square meter may be sufficient as the support|pillar of the tower|turret part 5, and the structure in which only one support|pillar is installed per area smaller than 1 square meter may be sufficient.

FIG. 4 shows an installation example of the temporary scaffolding unit 1 for construction according to this embodiment. In this installation example, the temporary construction scaffolding units 1 are installed at positions facing the opening of the building, and the footboards 20 are laid across the respective temporary construction scaffolding units 1 to install the scaffolding.

FIG. 5 shows an installation example of the temporary construction scaffolding unit 1 according to this embodiment. In this installation example, the temporary construction scaffolding unit 1 may or may not be installed at a position facing the opening of the building. This is the configuration to be installed. A plurality of temporary scaffolding units for construction 1 are connected by joints 9 made of metal. fixed. The intervals between the temporary construction scaffolding units 1 and the anchor bolts 7 can be changed as appropriate.

The turret 5 of the temporary scaffolding unit 1 for construction according to this embodiment may be three-dimensional, and may have various shapes such as a cylindrical shape, a prismatic shape, a conical shape, and a pyramidal shape. Also, the anchor bolt 7 can be made of various materials such as an adhesive system and a metal system.

A temporary construction scaffolding unit 3 according to a second embodiment of the present invention will be described with reference to FIG. In addition, in all the drawings below, in order to facilitate understanding, there are cases where the dimensions and ratios of the components are changed as appropriate. It should be noted that the same configuration as the temporary scaffolding unit for construction 1 according to the first embodiment may be given the same reference numerals, and the description thereof may be omitted.

FIG. 6 is a side view of the installed state of the temporary scaffolding unit 3 for construction according to this embodiment. The temporary construction scaffolding unit 3 is roughly divided into a scaffolding section 10 connected to a scaffolding section 5 provided inside a building and connected to the scaffolding section 5 . FIG. 2 is a perspective view of the tower 5 having frames 5b, 5b1, 5b2 and a base plate 5a. The yagura portion 5 is constructed by assembling a frame 5b into a yagura as shown in FIG. A base plate 5a is provided on each of the four columns of the tower portion 5, and four anchor bolts 7 are provided on the base plate 5a. The tower part 5 is fixed to the floor 50 by installing the anchor bolts 7 on the floor 50 of the building. As shown in FIG. 6, the scaffold section 10 has footboards 10a1, 10a2, 10a31, 10a41 and a frame 10b1 having different height positions. The temporary construction scaffolding unit 3 of this embodiment has a configuration in which 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-described embodiment. In addition, the tower section 5 and the scaffolding section 10 may each be provided with stairs. It should be noted that the tower section 5 may be fixed to the floor 50 using a weight.

By using the temporary construction scaffolding units 1 and 3 according to the embodiment of the present invention and the scaffolding installation method using the same, the following effects can be obtained.
(A) Since the construction temporary scaffolding units 1 and 3 are provided within the floor, it is possible to increase the work processes within the floor during the scaffolding installation work, thereby reducing the work time at high places (outside). and safety are ensured.
(b) Since the height position of the footboards connected to the tower 5 can be changed arbitrarily, it is possible to deal with various sites.
(c) Since scaffolding can be installed only on floors where it is necessary, it is possible to shorten the scaffold assembly work time, reduce the amount of scaffolding materials, and reduce the cost of transporting scaffolding materials.
(d) When performing pinpoint construction work outside the building, it is possible to significantly reduce the scaffold assembly cost.

Since the above-described embodiment is a preferred example of the present invention, various technically preferable limitations are applied, but the scope of the present invention is not unduly limited by the above description. Moreover, not all of the configurations described in the above-described embodiments are essential constituent elements of the present invention. Also, the configurations described in the above embodiments may be added or combined with each other.

INDUSTRIAL APPLICABILITY The present invention can also be widely used in temporary scaffolding for construction and a method for installing a temporary scaffold for construction.
