The present invention relates to a jockey supporting the ceiling and the ground in the upper and lower portions of the vertical pipe of the prefabricated scaffolding device. The present invention relates to a compatible jack that can be used to support both construction vertical pipes of different diameters and civil vertical pipes.

In construction and civil engineering, prefabricated scaffolding devices are members that are used as pedestals in various constructions, from conventional scaffolding frames that connect horizontally and vertically simply using rod-like members such as wood or pipes to modern prefabricated scaffolding devices. There is a kind.

The prefabricated scaffolding apparatus has a plurality of disks 11 and 12 and a plurality of disk-shaped fixed pipes fixed at regular intervals in the vertical direction to the vertical pipes 11 and 12, respectively. A connecting plate 2, a horizontal pipe 3 installed between the plurality of vertical pipes, and a member for prefabricating the horizontal pipes 3 to the connecting plate of the vertical pipe. It has a losing form and is connected to the connector (not shown) to which the horizontal pipe is fixed at the rear end, and a fixing wedge (not shown) for fitting the connector to the connecting plate 2 and fixing it, and assembled to the upper and lower ends of the vertical pipe to be vertical. It consists of a jack (4, Jack) for supporting the pipe.

The jack 4 is assembled to the front end of the vertical pipes (11, 12) to support the ceiling jack (41, U-Head Jack) and the lower side of the vertical pipes (11, 12) base to support the ground It consists of a jack 42 (base jack).

The vertical pipe 1 includes a civil engineering vertical pipe 12 and a construction vertical pipe 11, which is larger than the diameter (60.5φ) of the civil engineering vertical pipe 12 and the diameter of the construction vertical pipe 11 (48.6). φ).

The harmful jack 41 is perpendicular to the center of the harmful portion 411 and the bottom surface of the harmful portion formed by bending the plate-shaped body supporting the ceiling as shown in FIG. The rod-shaped body is fixed to the screw rod 412 screwed on the outer circumferential surface and the screw rod 412 to the inner circumferential surface is joined to the ring shape is assembled to be moved up and down and the handles to be rotated respectively on both outer peripheral surfaces of the body It consists of the raised nut ring 413 formed.

And the base jack 42 is a plate-shaped base plate 421 which is placed on the ground as shown in Figure 2 and the upper surface of the base plate 421 is erected in the form of a fixed rod and spiral screw on the outer peripheral surface The formed screw rod 422 and the screw rod 422 are joined to the inner circumferential surface to form a ring assembled to be able to move up and down, and are joined to the inner circumferential surface to form a ring assembled to be movable up and down and the handles to be rotated are rotated on both sides of the body. It is raised on the surface, respectively, and is composed of a hannut ring 423.

The conventional jack 4 having the above-described configuration is installed while supporting the ceiling and the ground on the upper and lower sides of the vertical pipe as described above. To be assembled and supported on two types of vertical pipes having different diameters, jacks having different specifications are provided. (4 ') is required.

That is, the conventional jack (Jack) has to be equipped with a civil jack (for example 4; 41, 42) and a building jack (for example 4 '; 41', 42 ') is a financial burden.

In reality, it is difficult to use a civil jack only because of economic problems in the civil engineering site, and it is difficult to provide a jack for construction, so it is inefficient to use a vertical pipe for civil engineering at the construction site.

The present invention is a invention invented to correct the problem that the jacks assembled and supported on the upper and lower sides of the vertical pipe in the prefabricated scaffolding device should be manufactured and used separately for civil engineering and building construction. Its characteristic is to provide a compatible jack that can be applied to all.

Compatible jack of the prefabricated scaffolding device according to the present invention is different in diameter on the bottom surface (nutring of the harmful jack) or the top surface (nutring of the base jack) of the nut ring provided on the harmful jack and the base jack of the upper, respectively It is characterized by forming two vertical pipe support surfaces of ring-shaped protruding rings to support both civil vertical pipes and construction vertical pipes. The smaller diameter ring-shaped building vertical pipe ground supports the upper and lower ends of the vertical pipes for construction, and the larger diameter vertical pipe grounds of the ring-shaped construction supports the upper and lower ends of the civil vertical pipes. The building vertical pipe ground and the civil vertical pipe ground are formed in different heights, but the construction vertical pipe ground is formed by being raised, and the inner diameter of the civil vertical pipe ground is formed on the construction vertical pipe ground. It is formed in connection with each other, the width of the two vertical pipe paper surface is characterized in that it is formed equal to or wider than the thickness of the vertical pipe.

The compatible jack of the assembled scaffolding device of the present invention having the configuration as described above will be described in detail with the accompanying drawings.

However, the terms or words used in the present specification and claims are regarded as concepts selected by the inventors as the best way to explain the present invention and the meanings consistent with the technical spirit of the present invention in grasping the technical contents of the present invention. It should be properly interpreted as a concept.
