Description

Technology Field

[0001] The present invention relates to a clamp-type connecting device for temporary construction pipes, and more specifically, to a clamp-type connecting device for temporary construction pipes that enhances the connection expandability and work safety of the temporary pipes by connecting a connecting member to a bracket provided on the outer surface of the left or right rotating member, while the left rotating member and the right rotating member constituting the clamp-type connecting device wrap around the outer surface of a vertical pipe and are fixed by a fastening bolt. Background Technology

[0003] Generally, when installing a building structure at a construction site, temporary workspace is temporarily secured to allow construction work to be carried out around the outer perimeter of the building structure by fixing the temporary pipes at the intersection points with clamps so that the temporary pipes are maintained in an orthogonal state or at various angles in the horizontal and vertical directions adjacent to the building structure.

[0004] Scaffolding installed using such temporary pipes is a temporary structure installed to allow work at high places during building construction, serving as a passageway for workers and a platform for work, as well as for transporting construction materials. Generally, such scaffolding is formed by interlocking pipes in vertical and horizontal directions to form a frame, and then installing platforms for movement or work between them. The scaffolding pipes forming the frame are installed vertically by driving post pipes into the ground at specified intervals, and beam pipes are connected to these post pipes in a horizontal direction. At this time, the method used to connect the post pipes and beam pipes is to tie them together using wires or to connect them using specially manufactured clamps.

[0005] A conventional clamp comprises a main body having a radius of curvature corresponding to the pipe formed on its inner surface so that a pipe is inserted therein, and a cover having a radius of curvature corresponding to the pipe formed therein so as to surround the pipe together with the main body and rotatably hinged to one end of the main body, and a tightening bolt hinged to the other end of the main body to tighten and fix the inserted pipe by fastening it to the cover. A clamp with such a configuration is used by connecting multiple clamps together to connect the pipe in a vertical or horizontal direction, or by forming a fastening hole on one side of the main body and inserting a wire into the fastening hole to fix the clamp. The pipe installed by such a clamp is supported by a separate wire on the wall of a building.

[0006] However, when pipes are joined together using such conventional clamps and then separately supported on a wall by a wire, the work of joining the pipes by the clamps and the work of fixing the pipes to the wall by the wires must be performed, which not only makes the scaffolding installation work cumbersome, but also, in order to reinforce the joining force of the pipes fixed by the wires, the posts serving as supports must be erected at a considerable depth in the ground for safety reasons, which significantly increases the time required to install the scaffolding. Furthermore, there was a risk of safety accidents occurring if the pipes collapsed due to the wires not being securely fixed to the wall, and there were also problems regarding the lack of expandability for connecting pipes and insufficient work safety.
