Description

In the present invention, when installing a building site on a suspended scaffolding, an auxiliary pipe attachment tool used to attach an auxiliary pipe for erection of the building site to the side of a scaffolding panel constituting the suspended scaffolding, and The present invention relates to a building construction structure using the auxiliary pipe fitting.

Suspended scaffolding with a large number of scaffolding panels connected is used for construction at high places. As a scaffolding panel, there is one in which the applicant has previously obtained a patent right (Patent Document 1).

As shown in FIG. 5, the scaffolding panel A has a rectangular scaffolding plate (for example, metal) on the upper surface of a peripheral frame provided with two elongated lumbers B, two connecting pipes (frame pipes) C, and a reinforcing material D. Flat plate, control panel material, expanded metal, or other scaffolding board) E is arranged and fixed. There is a gap F between the reinforcing material D on both ends in the longitudinal direction and the frame pipe C, and a locking material G connecting the reinforcing material D and the frame pipe C is provided between the reinforcing material D and the frame pipe C. The scaffolding panel A includes a scaffolding panel A having a length of 2000 mm and a width of 660 mm, a scaffolding panel A having a length of 3000 mm and a width of 660 mm, and a scaffolding panel A having a length of 3850 mm and a width of 660 mm.

As shown in FIG. 6, the scaffolding panel A is suspended by being locked by a suspension chain I suspended from a frame (main girder) H of an elevated road, an iron bridge, or the like, and is suspended vertically and horizontally to be connected to the suspension scaffold. Can be formed. A joint J as shown in FIG. 5 is used to connect the scaffolding panel A in the lateral direction. As shown in FIGS. 7 (a) and 7 (b), this joint J has two half-split pipes having different diameters (hereinafter, the small-diameter half-split pipe is referred to as "small-diameter half-split pipe J1", and the large-diameter half-split pipe is used. The pipe is equipped with a "large diameter half-split pipe J2"). A nut J3 is fixed to the inner surface of the small-diameter half-split pipe J1. A connecting hole J4 and a retaining hole J5 penetrating in the vertical direction are penetrated at locations near both ends of the half-split pipes J1 and J2 in the axial direction.

In this joint J, when the adjusting bolt J7 is screwed into the nut J3 from the through hole J6 of the small-diameter half-split pipe J1 and the tip thereof is pressed against the inner surface of the large-diameter half-split pipe J2, the small-diameter half-split pipe J1 is pushed up and both halves. The diameter of the pipe composed of split pipes J1 and J2 expands, and when the adjusting bolt J7 is loosened, the small-diameter half-split pipe J1 descends along the adjusting bolt J7, and the pipe composed of both half-split pipes J1 and J2. It is configured to reduce in diameter.

Japanese Patent No. 2647801 Japanese Patent No. 5654710

As shown in FIG. 8A, the applicant considered that the building site K should be erected on the frame pipe C of the scaffolding panel, but the length of the scaffolding panel A is at least 2000 mm, whereas the length of the scaffolding panel A is at least 2000 mm. Since the Industrial Safety and Health Act stipulates that the distance W between adjacent building sites K should be within 1850 mm, this standard may be applied if the building sites K are attached to both frame pipes C of one scaffolding panel A. Can't meet.

Further, even if the building site K is to be erected at intervals that meet the standards of the Industrial Safety and Health Act, as shown in FIG. 8 (b), the building site K is located at a position 1850 mm from one of the frame pipes C on which the building site K is erected. There is a scaffolding board E, and the building site K cannot be erected.

As shown in FIG. 9A, it is conceivable to attach the clamp L to the frame pipe C, fix the auxiliary pipe M to the clamp L, and erect the building site K on the auxiliary pipe M. (B) As shown in (c), even when the auxiliary pipe M is provided, the opening / closing tool K1 of the single clamp on the building K side passes between the auxiliary pipe M and the scaffolding plate E of the scaffolding panel A. Since there is not enough space to do so, the auxiliary pipe M cannot be held by the single clamp of the building site K, and the building site K cannot be erected.

In addition to the above, as shown in FIG. 10, one of the clamps L is attached to the joint J protruding to the side of the scaffolding panel A, the auxiliary pipe M is fixed to the other of the clamps L, and the construction site is attached to the auxiliary pipe M. It is conceivable to erect K (see FIG. 9B), but using the joint J for such a purpose has a problem in strength.

The present invention has been made in view of the above circumstances, and the problem to be solved is to use an auxiliary pipe that enables the construction site to be erected at predetermined intervals when it is installed outside the scaffolding panel constituting the suspended scaffolding. It is an object of the present invention to provide an auxiliary pipe fitting and a construction site erection structure using the auxiliary pipe fitting.

[Auxiliary pipe fixture]
The auxiliary pipe fitting of the present invention is used by being attached to a joint projecting to the side of a scaffold panel constituting a hanging scaffold, and is covered with a tubular covering having an end face opening to cover the joint. It is equipped with a stopper for fixing the tool to the joint and an end cap. The end cap is provided at the end opposite to the end face opening of the covering, and has an insertion hole for inserting the stopper at a position of the covering that is not hidden by the end cap.

[Building site erection structure]
Construction land upright structure of the present invention, hanging a structure with erected Kenchi on the side of the scaffold panel constituting the scaffold, auxiliary pipes attached to two or more joints which projects to the side of the scaffold panel The ingredients are attached . The auxiliary pipe fitting includes a covering for the joint and a stopper for fixing the covering to the joint, the auxiliary pipe fitting is held on one side of the clamp, and the auxiliary pipe is held on the other side of the clamp. Two or more buildings were erected on the auxiliary pipe at predetermined intervals.

[Auxiliary pipe fixture]
Since the auxiliary pipe fitting of the present invention enables the installation of an auxiliary pipe for erection of a building on the outside of the scaffolding panel, a solution has not been found so far, and the scaffolding panel can be built in the longitudinal direction. The ground can be erected.

[Building site erection structure]
In the building site erection structure of the present invention, since the building site is installed outside the scaffolding panel, the work space is not unnecessarily narrowed.
