Abstract

PROBLEM TO BE SOLVED: To provide a connector used for the attaching of struts of a guide rail, which is used to ensure safety of workers while being provided on a temporary scaffold frame built up on a construction spot, and to which a safety belt is attached, and for the bonding sections of the guide rail. SOLUTION: A clamp main body which is used for a temporary scaffold is constituted into a shape having an approx. square cross section by providing a back surface section, an upper edge section, a bottom edge section and an opening on the front side. On the upper edge section, a rotary clamping piece is provided at one section, and a bent section at the tip end and the back surface plate are fixed with a fixing utensil. Then, a guide rail is passed in the clamp main body, and clamped. Also, a connector being pinched by the outer peripheries of confronted bonding sections of the guide rail, which is fitted in and supported by the clamp main body, is formed into a shape having a square cross section with an upper surface working plate and a lower surface working plate, and a horizontal opening is formed by providing a bent edge on respective tip ends. Then, the rear end sections of the upper surface working plate and the lower surface working plate are detachably fixed with fixing utensils such as a bolt and a nut.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a guide rail for supporting a slide of a safety belt connected to an operator to be mounted on a temporary scaffold to be framed at a construction site. The present invention relates to a fastening device and a connection device for a temporary scaffold safety belt guide rail with a fastening device to be mounted and a connection device for connecting a guide rail.

[0002]

2. Description of the Related Art Generally, in a safety tool for workers on a temporary scaffold of this kind, a safety belt made of a rope or the like is required to work on a scaffold plate after construction of the scaffold.
Because it is very troublesome and inconvenient to use, a troublesome safety belt may not be used, causing an accident such as dropping.

In the conventional temporary scaffold, a worker working on a scaffold plate is obliged to use a safety belt or the like. There are drawbacks in the cross-sectional shape of the guide rail on which the metal fittings are mounted, the problem that the operation of attaching and detaching the sliding metal fittings is very troublesome, and the mounting of the guide rail to the support is not simple and reliable.

[0004] Further, since the length of the guide rail serving as a handrail frame is a maximum of 1.8 m, there is no metal fitting firmly connected at the connection between the guide rail and the guide rail in the middle. There is a problem that use is very troublesome and inconvenient.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and its main object is to attach various types of columns to the columns by using column clamps. Since the main body of the fastener needs to firmly support the guide rail moving the safety belt, after clamping the guide rail, the rotating fastening piece of the main body of the fastener is attached to the back plate for firm support. Thus, the guide rail is firmly fixed to prevent the guide rail from being detached. In addition, the connecting portion of the guide rail requires strength for the movement of the safety belt, and is a point that the upper plate and the lower plate are firmly fastened with the fixing tool.

[0006]

In order to achieve the above-mentioned object, the fastener body of the present invention is formed in a substantially rectangular cross section having a back plate, an upper side, a bottom side, and an opening at the front. The upper side portion is provided with a pivotal fastening piece in a part to make it freely openable, and the bent portion at the tip of the pivotal fastening piece and the back plate are firmly fixed with a fixing tool, and tightened. The guide rail is inserted and supported inside the tool body. In addition, the connection fittings of the guide rails of the connecting portion mounted and supported on the fastener main body are provided with an upper surface contact plate and a lower surface contact plate. A curved edge is provided to form a horizontal opening. In addition, the rear end portions of the upper and lower contact plates are fixed so as to be detachable with a fixing tool.
