2. Description of the Related Art When performing external work on a veranda or the like in a medium- or high-rise apartment building, conventionally, external scaffolds are generally assembled from the ground using a frame scaffold unit in consideration of work safety and the like.

[0003]

However, in the conventional scaffold assembly, when assembling an external scaffold at a high place, such as a veranda on the 10th floor, a large number of frame scaffolding units are required because they are assembled from the ground. Transporting and securing a storage space became very troublesome, and assembling and dismantling of the scaffold required a great deal of time and labor, causing a rise in construction costs. In this case, it is possible to assemble the overhanging scaffold with, for example, a veranda and overhang from the veranda. However, the overhanging scaffolds conventionally provided do not have a problem in terms of work safety or are not relatively safe. There was a problem that the configuration was complicated and the assembly and disassembly required a great deal of trouble.

An object of the present invention is to provide a support for a frame scaffolding frame which can easily and easily assemble an overhanging scaffold by applying a frame scaffolding unit.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the accompanying drawings.

As shown in FIG. 1, the supporting bracket of the present invention has a downwardly U-shaped fitting stopper 1 and an outer side 1b of the fitting stopper 1.
Bracket part 2 that protrudes horizontally outward from the upper end of the
The fitting stopper 1 and the bracket 2 are made of a high-strength material, for example, a square pipe made of steel. To support the bracket 2 from below, the bracket 2
A brace member 3 made of, for example, a steel round pipe is provided between the outer side portion 1b and the outer side portion 1b.

[0008] The fitting stopper 1 is directed downward from the upper end to a concrete protective wall b having an open upper end which rises from the outer end of a concrete floor a (see Fig. 5) such as a veranda on each floor of an apartment building or a landing in a common corridor or a common staircase. A gap having a width exceeding the thickness of the protective wall b is formed between the inner and outer side portions 1a and 1b. The thickness of the protective wall b varies somewhat depending on the scale and grade of the building, and is set to an interval slightly larger than the maximum thickness of the protective wall, for example, an effective interval of about 250 mm. By the way, the thickness of the protective wall is at most 20
It is about 0 mm.

The effective length (depth that can be fitted) of both side portions 1a and 1b is preferably larger than the effective distance between both side portions 1a and 1b in consideration of the safety at the time of fixing to the protective wall b. In the illustrated embodiment, a case is shown in which the size is set to about 3 to 5 times the effective interval.

On both side portions 1a and 1b, clamp screws 5 are provided which advance and retreat in the front-rear direction as they are rotated by the guidance of a screwing portion with the nut member 4. The clamp screw 5 is for fastening and fixing the fitting stopper 1 in the state of being fitted into the protective wall b. In the drawing, a pair of front and rear, two upper and lower pairs are shown. A pressing member 5a is provided at the tip of the clamp screw 5, and the pressing member 5a is, for example, a disk-shaped disk, and is attached to the tip of the clamp screw 5 at the center so as to be freely rotatable around the central axis. Fixed.

The thickness of one protective wall b should be the same over the entire length in the vertical and horizontal directions, but in practice there is some variation due to unevenness of the wall generated during construction. . In this case, if the crumb screws 5 are provided so as to face the front and rear sides of each of the side portions 1a and 1b, variations in the thickness of the protective wall b can be finely adjusted by entering and leaving the clamp screws 5 and 5.

In order to facilitate visual confirmation of the tightening amount of the clamp screw 5, a plurality of, for example, three (see FIG. 2) marks 6 arranged in the axial direction are predetermined at a portion near the outer end of the clamp screw 5. At a pitch of, for example, about 20 mm. Although a circumferential groove is shown in FIG. 2 as the mark 6, it is not particularly limited as long as it does not hinder screwing with the nut member 4.

The upper side 1c of the fitting stopper 1 is provided at an intermediate position with an adjustment screw 8 which moves up and down in the vertical direction as it is rotated by the guidance of a threaded portion with the nut member 7. The adjusting screw 8 is for adjusting the mounting height of the fitting stopper 1 to the protective wall b. A pressing member 8a is rotatably mounted and fixed to the tip of the adjusting screw 8 as in the case of the clamp screw 5.

The bracket portion 2 is a portion that protrudes outward from the protective wall b, and is a frame scaffolding unit A (FIGS. 5 and 6).
(See FIG. 1), the width of the overhang is slightly larger than the distance between the front and rear pillars A11, A11.

At the base end side and the tip end side of the bracket portion 2, there are provided joining pipe portions 9, 9 projecting upward, and the joining pipe portions 9, 9 are provided.
