の外廻り、特に下屋に使用される足場脚部用連結具に関
する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting device for a scaffolding leg used mainly for the outer periphery of a wooden house, particularly for a shed.
【０００２】[0002]
【従来の技術】木造住宅では、和室に続く広縁や廊下部

となる。2. Description of the Related Art In a wooden house, a one-story house without a second floor is sometimes used as a wide margin or corridor following a Japanese-style room. Such a one-story building is called a lower house, but in a total two-story house without a lower house, a scaffold can be erected on the ground and the area around the eaves with a large two-story roof can be constructed. In a house with a shed, the scaffold separates from the eaves on the large roof with the depth of the shed, making it difficult to ensure sufficient work safety.
【０００３】そのため、下屋のある場合には、図９に示

るのが一般的である。[0003] Therefore, when there is a scaffold, as shown in FIG.
And the roof of the second-floor large roof 3 is laid, and then the scaffold is once loosened and the roof 1 of the roof is tiled. It is common to construct the surroundings.
【０００４】[0004]
【発明が解決しようとする課題】ここで、足場２の解体

め込んである。When the scaffold 2 is dismantled, it is necessary to remove the jack base, which is the leg of the scaffold 2 placed on the roof 1 of the shed. , Is fitted inside the vertical frame pipe constituting the scaffold 2.
【０００５】そのため、ジャッキベースを取り外すに

再度立設する際にも同様に生じる。[0005] Therefore, to remove the jack base, it is necessary to lift the vertical frame pipe 4 of the scaffold 2 as shown in FIG. 10, but the scaffold 2 is horizontally moved along with other scaffolds surrounding the building. Because of the connection, it is not easy to lift only the vertical frame pipe 4 of the scaffold. Therefore, not only the scaffold 2 but also the scaffold laterally connected thereto must be lifted together, or if it is not possible, the scaffold 2 or the scaffold laterally connected thereto must be dismantled once. However, there has been a problem that a large number of workers and labor are required to remove the jack base 5 placed on the roof 1 of the shed. Such a situation also occurs when the jack base 5 is placed on the roof 1 of the shed and the scaffold 2 is erected again.
【０００６】本発明は、上述した事情を考慮してなされ

くなる。The connection between the upper end of the connecting member and the lower end of the vertical frame pipe is also optional. If the load from the vertical frame pipe is supported by the connecting member and both sides can be prevented from laterally displacing, Such a connection method may be used. For example, a method of screwing the upper end of the connecting member into the lower end of the vertical frame pipe is also conceivable. However, if the upper end of the connecting member is configured to be fitted into the lower end of the vertical frame pipe, the lifting and lowering operation of the height adjustment support cylinder is performed. As the connection member also rises and falls naturally with
There is no need to remove the connection between the vertical frame pipe and the connecting member.

The support tube for height adjustment and the inner tube member are inserted slightly below the vertical frame pipe from the side while being slightly lowered as necessary, and then the vertical frame pipe and the inner tube member are fitted inside the outer tube member. To return the outer cylinder member to the holding position. And
If necessary, the height adjustment support cylinder is slightly rotated in the reverse direction to bring the upper end of the inner cylinder member into contact with the lower end of the vertical frame pipe.

構成することができる。The structure and shape of the inner and outer cylinder members are arbitrary. For example, the inner cylinder member is formed of a cylindrical body having an inner diameter into which the male screw portion of the jack base can be inserted, and the outer cylinder member has an outer shape. The outer cylinder member can be composed of a cylindrical body having an inner diameter.

If the member is configured to be screwed into the inner cylinder member and the vertical frame pipe, holding and lifting can be performed by turning the outer cylinder member and adjusting its height position,
If a locking mechanism for holding such an outer cylinder member in the vicinity of the contact position between the vertical frame pipe and the inner cylinder member is provided, by switching the locking mechanism between a locked state and a released state, In addition, it is possible to quickly perform holding in the vicinity of the contact position and evacuation by elevating. As the locking mechanism, for example, a pin that penetrates the outer cylinder member and the inner cylinder member is removably inserted, and a protruding projection provided on the peripheral surface of the inner cylinder member is fitted into a fitting hole of the outer cylinder member. Mechanism is considered.

ベースの再設置が可能となる。Further, if the outer cylinder member is connected to the inner cylinder member via a predetermined expansion / contraction mechanism instead of the locking mechanism, the inner cylinder member is simply pulled down so as to resist the expansion / contraction mechanism. The jack base can be removed by exposing the vicinity of the contact position between the cylindrical member and the vertical frame pipe, and the jack base can be removed just by releasing the hand from the outer cylindrical member with the jack base positioned immediately below the vertical frame pipe. The cylinder member jumps upward by the action of the expansion and contraction mechanism and is fitted into the vertical frame pipe, so that the jack base can be reinstalled.
