Abstract

PROBLEM TO BE SOLVED: To facilitate the setting of an external auxiliary equipment part by fastening a U-shaped mounting fitting to the upper end of a veranda, and erecting an external strut extending over a plurality of floors through this fitting, and setting a work scaffold on the external strut. SOLUTION: U-shaped mounting fittings 5, 6 having clamps 10, 11 are attachably and detachably mounted on the upper ends of the raised parts 3, 4 of verandas 1, 2 of each floor through fastening bolts. An external strut 18 having a slide bracket 19 is stood at prescribed intervals through the mounting fittings 5, 6, and a scaffold 17 is formed while regulating the height of a scaffolding board 20. A scaffold can be thus erected extending over a plurality of floors, and even if no setting space or wall connecting anchor is present, a work scaffold or auxiliary equipment part such as external curing means can be set. Accordingly, an auxiliary equipment part can be easily and firmly set in an optional floor.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for installing an external support temporarily provided outside of an outer wall of a building for construction.

[0002]

2. Description of the Related Art In the case of installing external auxiliary equipment for construction work installed outside a frame such as a work scaffold or external curing means, conventionally, a round pipe or a clamp has been used on site. 2. Description of the Related Art A widely used method is to form a supporting framework from the ground and attach a target construction auxiliary device to the framework. However, in the case of this installation method, the number of members used is large and there is a problem in workability, and a certain installation space is required on the ground. In particular, when no anchor for connecting the wall was installed on the skeleton side, work for reinforcement such as staying was required.

[0003]

SUMMARY OF THE INVENTION The present invention has been developed in view of such a conventional situation, and its object is not to rely on a wall connecting anchor installed on the skeleton side. Another object of the present invention is to provide a method of installing an external support that can be easily and firmly installed.

[0004]

According to the present invention, a substantially U-shaped mounting bracket is removably fastened and fixed to an upper end of a rising portion formed on a veranda of a plurality of floors, and at least two or more of them are fixed. The technical means of mounting the external strut over a plurality of floors using the mounting bracket was adopted.

[0005]

According to the present invention, the technical means of mounting the external strut over a plurality of floors by using two or more mounting brackets fixed to the rising portions formed on the porch of the plurality of floors is adopted. By the work, a strong installation state over multiple floors can be obtained. It is to be noted that by appropriately selecting the number of floors on which the external struts are to be installed, installation on an intermediate floor is possible. Thus, external auxiliary equipment for construction, such as a work scaffold, which is installed via the external support, is also easily and firmly installed.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an installation state diagram showing an installation state of a scaffold as one embodiment of the present invention, and FIG. 2 is a partially enlarged view thereof.
In the figure, 1 and 2 are examples of verandas of appropriate floors.
Reference numerals 3 and 4 are the rising portions. Reference numerals 5 and 6 denote mounting brackets fixed to the upper ends of the rising portions 3 and 4. As shown in FIG. 3, the mounting brackets 5, 6 are composed of vertical members 7, 8 and a horizontal member 9, and are formed in a substantially U-shape so as to fit into the upper ends of the rising portions 3, 4. I have. One vertical member 7
Is formed from a square pipe so as to stably contact the outer surfaces of the rising portions 3 and 4, and an appropriate number of clamps 10 and 11 are attached to the outer surfaces. The other vertical member 8 is formed of a round pipe, and the lower portion thereof has the rising portions 3 and
4 is provided with a fastening means comprising an internal thread 12 and an L-shaped fastening bolt 14 having a pressing portion 13 at the tip, which can be fastened to the inner side surface of the screw 4. The horizontal member 9 is formed of a square pipe so as to stably contact the upper end surfaces of the rising portions 3 and 4. These members are connected to each other in a U-shape by welding or the like. Furthermore, in this embodiment, the lower member of the support member 15 installed between the upper end of the rising portion 3 of the lower floor veranda 1 and the lower surface of the upper floor veranda 2 is engaged with the upper surface of the horizontal member 9. Possible inverted U-shaped locking part 1
6 are provided. 4 is a plan view of the mounting brackets 5, 6, and FIG. 5 is a bottom view thereof.

However, in the case of the present embodiment in which a scaffold is installed, first, as shown in FIG. 1, the upper end portions of the rising portions 3 and 4 of the verandas 1 and 2 on each floor according to the installed scaffold. The mounting brackets 5 and 6 are fastened and fixed at predetermined intervals.
This tightening and fixing is performed by tightening the tightening bolts 14 in a state where the horizontal members 9 of the mounting brackets 5 and 6 are placed on the upper surfaces of the rising portions 3 and 4, respectively. The pressing is performed by pressing the pressing portion 13. As a result of this tightening and fixing, the inner surface of the vertical member 7 is pressed against the outer surfaces of the rising portions 3 and 4, so that a stable contact state is obtained. Note that loosening can be prevented by further screwing a fixing double nut (not shown) to the outside of the nut constituting the female screw portion 12.

Next, as shown in FIG. 1, external posts 18 for installing a scaffold 17 are erected at predetermined intervals via clamps 10, 11 of the mounting brackets 5, 6 installed on each floor. Thereafter, the scaffolding plate 20 is installed at a predetermined height via the slide bracket 19 attached to the external support 18. In the figure, reference numeral 21 denotes a vertical rod supported in parallel with the external support 18, reference numeral 22 denotes a clamp for fixing the same,
Reference numerals 3 to 26 denote horizontal rod fixing clamps for connecting and supporting the external columns 18 or the vertical columns 21. In addition, by connecting and supporting appropriate positions on the outer support column 18 side and the vertical rod 21 side with a connecting rod (not shown), both are supported in parallel at a predetermined interval.

The rising part 3 of the veranda 1 on the lower floor
When the support member 15 is installed between the upper end of the support member 15 and the lower surface of the veranda 2 on the upper floor, an inverted U-shape in which the lower end of the support member 15 projects from the upper surface of the horizontal member 9 of the mounting brackets 5, 6 It can be installed very easily by engaging with the locking part 16 of a shape. In the figure, reference numeral 27 denotes an adjusting means for expanding and contracting the length of the support member 15.

As described above, according to the present invention, the external columns 18 are fixed across a plurality of floors by using the mounting brackets 5, 6 fixed to the rising portions 3, 4 formed on the verandas of the plurality of floors. With this configuration, it is possible to easily install the external support 18 having a strong support state. Therefore, external auxiliary equipment for construction, such as a scaffold, which is installed via the external strut 18, can be easily and firmly installed. The number of clamps installed on each mounting bracket is 1
The number may be one or more. Further, the vertical members 7, 8 and the horizontal member 9 constituting the mounting brackets 5, 6 are not necessarily required to be pipe-shaped, may be solid, and need not necessarily be made of metal.

[0011]

According to the present invention, by using the rising portions formed on the verandas of a plurality of floors, the external columns can be easily and firmly installed, and the number of floors on which the external columns are installed can be appropriately adjusted. You can choose.
