DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of constructing a building or a structure, in which a temporary supporting column of a scaffold is stably and easily mounted on a column or wall such as a steel frame or a beam serving as a support base. The present invention relates to a connection fitting to be held.

[0002]

2. Description of the Related Art Conventionally, when assembling an external scaffold at the time of construction of a building or a building, or at the time of exterior construction or repair work of an existing building, a scaffold support is connected to a column such as a steel frame or a beam already assembled. It is held using metal fittings.
The cross-section shape and size of the pillar serving as the mounting base are different depending on the site, and the assembling position of the scaffold, that is, the distance between the pillar serving as the mounting base and the scaffolding post is slightly different depending on the site. A wide variety of connecting brackets were required to connect the device.

[0003]

Therefore, according to the present invention, it is possible to hold a pillar or a veranda etc. on a wall such as a veranda irrespective of the cross-sectional shape and size of the pillar as a mounting base, and furthermore, the pillar and a scaffold support. And a connecting bracket that can easily and surely hold a pillar or a scaffolding support serving as an attachment base, in addition to being able to freely adjust the length of the fitting in accordance with the distance between the support and the base. Accordingly, an object of the present invention is to solve the above-mentioned conventional problems.

[0005]

Embodiments of the present invention will be described below with reference to the drawings. FIGS. 1 to 4 show an embodiment of a connection fitting according to the present invention. The connection fitting is a pair of members that sandwich a column C such as a steel frame or a beam of a structure serving as a support base. 2 having clamp pieces 2a and 2b
And a ring body 1 for holding and holding the scaffolding support A, and a telescopic shaft 4 connecting the ring body 1 and the clamp 2. The clamp 2 and the ring body 1 including the clamp pieces 2a and 2b are preferably made of a metal material such as iron or stainless steel that has been subjected to rust-proofing.

The ring body 1 has a pair of left and right ring half bodies 1a, 1 connected to be openable and closable about a pivot 1c as a fulcrum.
b, and a fastening means 3 for fastening and releasing the free end portion is provided at the opposite free end portion of the ring half body. In this embodiment, as an example of the fastening means 3, a bolt member 3a is swingably attached to the free end of one ring half body 1a, and a groove 3b having an open end for receiving the bolt member 3a detachably is provided. The free ends of the left and right ring half bodies 1a and 1b are formed by inserting the bolt member 3a into the groove 3b and tightening the nut member 3c from the tip side. It is formed so that.

The left and right clamp pieces 2a and 2b of the clamp 2 are formed so that the distance between them can be changed by the elongated hole 6 and the pin 7. One clamp piece 2a is fixed to one end of the outer cylinder 4a of the telescopic shaft 4.

Further, the other clamp opposing the clamp piece 2b
These clamp pieces are screwed forward with respect to the lamp piece 2a.2
a,2b to tighten and fix the column C sandwiched by
Attachment means 5 is provided. In this embodiment,
Clamping means 5 clamps bolt 8 from outside clamp piece 2b.
The clamp piece 2 is rotatably extended toward the pump piece 2a.

Is formed. In the drawing, reference numeral 10 is for slip prevention.
1 shows a resin cover.

An inner screw 4b is formed at the other end of the outer cylinder 4a of the telescopic shaft 4, and a screw shaft 4c extending from the ring body 1 is screwed into the screw hole 4b. Screw shaft 4c
Is rotatably connected to the ring body 1, and a horizontal bar 11 for rotation is provided in a middle portion of the screw shaft.

[0010] As shown in FIG. 4, the connection fitting thus formed is fixed by clamping the clamp 2 to a column C serving as a mounting base, and then opening the ring 1 as shown in FIG. 3. The outer ends of the scaffolding pillars A are externally fitted to each other, and the bolt members 3a are inserted into the grooves 3b, and the nut members 3c are tightened from the distal ends to fasten the free ends of the left and right ring half bodies 1a and 1b. And fixed to the column A. The distance between the column C and the scaffolding column A is a horizontal bar 11.
By rotating the screw shaft 4c, the telescopic shaft 4 can be expanded and contracted for adjustment. Further, since the clamp 2 can rotate with respect to the screw shaft 4c, the clamp direction can be arbitrarily changed.

The ring half-body 1a, 1 according to the present invention.
Means 3 for freely opening and closing the free end of b is not limited to the mechanism shown in the above embodiment. For example, a fastening mechanism such as a buckle, which is often used to fasten the lid of a bag or tool box so that it can be freely opened and closed, that is, a rectangular loop body is hooked on an engagement portion of the other party and tightened by inversion. Fixing means and other commonly used mechanisms can be applied. The means for rotating the screw shaft 4c is such that, instead of the horizontal bar 11, a different-diameter portion such as a hexagonal or square compression flat portion is formed on the exposed portion of the screw shaft 4c and rotated with a tool such as a wrench. It may be. Other in the present invention,
The present invention can be implemented by appropriately modifying within a range having the constituent requirements, achieving the object of the present invention, and having the following effects.

[0012]

As described above, the connecting bracket of the present invention is constructed as described above, so that it can be tightly held by the column or the like regardless of the cross-sectional shape or size of the column or wall serving as the mounting base. At the same time, the distance between the clamp and the ring can be arbitrarily expanded or contracted in accordance with the distance between the column and the scaffolding support, so that one type of connecting bracket can be used in various ways, and parts management and arrangement Can be simplified. In addition, by releasing the fastening means for the scaffolding pillar and opening the ring half, it can be easily attached and detached from the side, and a clamp piece for the pillar etc. which will be the mounting base It can be easily attached and detached, which makes it possible to easily and quickly perform assembly and disassembly work at the time of construction, as well as to ensure the safety of construction and prevent the occurrence of accidents beforehand. is there.
