Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a corner connecting fitting for a frame scaffold temporarily installed for new construction or renovation of a building.

[Conventional technology]

Conventionally, in constructing a framework scaffold as described above, the first step is to
As shown in FIGS. 5 and 16, a large number of building frames 1 are used. The building frame 1 has a basic configuration in which both ends of a horizontal pipe 3 are welded and fixed to the upper ends of two vertical pipes 2. Then, a pair of building frames 1 are made to face each other at a predetermined interval, and the opposing vertical pipes 2 of these building frames 1 are connected by braces 4, and two frame fabric boards are placed on the opposing horizontal pipes 3. 5 are engaged and supported to form a large number of rectangular parallelepiped framework bodies 6, and these framework bodies 6 are connected in the horizontal and vertical directions to construct a framework scaffold. By the way, corner parts are often provided in scaffolding to match the shape of the building being newly constructed or renovated, but at corner parts bent at right angles, as shown in FIG. Butt the end face of the other frame body 6 against the
Both adjacent framework bodies are fixed.

However, in this framework scaffold, as is clear from FIG. 16, the braces 4 of one of the framework bodies 6 cross over the cloth board 5 at the corner, so the worker can move large pieces of material over the cloth board 5. The braces 4 get in the way and pose a danger when passing by or carrying work equipment.

Therefore, at the corner part of the framework scaffold, the other end surface should not be brought into contact with the side surface of the adjacent framework body.
For example, by bringing the insides of adjacent frame bodies close to each other on the inside of a building, and separating them on the outside to form a space with a square plane on the outside, frame bodies adjacent at the corner part can be connected to each other through members provided in this space. It is possible to connect them.

[Problem that the invention attempts to solve]

As mentioned above, in order to connect adjacent frame bodies at the corners of a frame scaffold through members provided in the space, it is possible to make the building frames that make up the frame bodies strong and to connect them with simple work. However, in the past, there were no connecting fittings dedicated to connecting parts of building frames that are close to each other at corner parts, and it was not possible to meet the above request. Connect via. There is a problem in that the construction of a framework scaffold is troublesome, and this framework scaffold is hardly used at present.

The present invention solves the above-mentioned problems and has a simple construction of corner connecting fittings for frame scaffolds that can firmly connect the adjacent parts of building frames at the corners with simple work. By providing the present invention at a low cost, the present invention is intended to be useful in realizing a framework scaffolding in which a space is provided in a corner portion as described above and frame bodies are connected by a member provided in this space.

[Means for solving problems]

The present invention is a corner connecting fitting for a frame scaffold that connects a building frame, which has a basic structure in which both ends of a horizontal pipe are fixed between the upper ends of two vertical pipes, in close proximity only on one side, the inside and the outside. A metal fitting body is provided at both ends with a fitting portion having a circular or semicircular plane in which the vertical pipes of adjacent building frames that are close to each other are fitted at the corner portion of the framework scaffold, and both ends of this metal fitting body are provided. It is provided with U-shaped or semicircular engaging members whose vertical cross sections are open to the lower surface and which are fixed to the outer circumferential surfaces and engage and support the horizontal pipes of the adjacent building frames from above.

[Effect]

The corner connecting fitting according to the present invention has a simple structure in which engaging members with openings on the bottom are fixed to the outer circumferential surface of both ends of the fitting main body, which has fitting parts at both ends. Connecting from above by fitting the fitting portions of the metal fittings into the upper ends of vertical pipes of adjacent building frames that are close to each other, and by engaging and supporting the engaging members with horizontal pipes of adjacent building frames. By simply pushing the metal fittings into the building frame, it is possible to position and hold the parts of adjacent building frames in close proximity to each other and firmly connect them. Then, one side of the building frames is brought close to each other and the other side is separated to form a space, and adjacent frames are connected via a member such as the corner cloth board provided in this space, and the corner parts are connected. It is useful for creating a framework scaffolding that has corner sections where there are no obstacles such as braces on the cloth board and where workers can safely pass over the cloth board at the corner while holding large materials or work equipment. .

[Effect of idea]

As explained above, the corner connecting fitting for a framework scaffold according to the present invention has a simple structure in which engaging members whose bottom surfaces are open are fixed to the outer peripheral surfaces of both ends of the fitting main body, which has fitting parts at both ends. Although it can be obtained at low cost, the fitting part of the fitting body is fitted into the upper ends of the vertical pipes of the building frames of adjacent framework bodies at the corner parts of the framework scaffolding, and the engaging member is fitted into the upper ends of the vertical pipes of the building frames of adjacent framework bodies. By engaging and supporting the horizontal pipes of the frame from above, the parts of adjacent building frames that are close to each other can be positioned and firmly connected by simply pushing the connecting fittings into the building frame from above. Therefore, by appropriately using corner cloth boards, corner braces, and corner vertical pipes, one side of the building frame is brought close to the other and the other side is spaced apart to form a space. Adjacent framework bodies are connected through members such as the corner cloth boards provided in the space, and there are no obstacles such as braces on the corner cloth boards, making it easy to carry large materials or work equipment. This has the effect of helping to realize a framework scaffolding with corner sections that allow workers to safely pass over the cloth boards at the corner sections.
