Extendable cage for construction

Abstract

A cage for construction work is provided with an extendable function. More particularly, a cage for construction work with an extendable function is provided which is formed so as to have both extendibility and safety by allowing for lateral extension of a cage used in finish work for the outer wall of a structure when constructing the structure and integrally forming a guard net for preventing falls on an upper part thereof.

1 . A cage for construction work with an extendable function comprising;
 a frame formed by connecting a vertical bar and a horizontal bar to each other and integrally formed at an upper side thereof with a frame for a vertical guard net;   a walk plate provided on the upper surface of the horizontal bar;   a guard net assembled to the upper and lower surfaces of the frame for the vertical guard net; and   an extending frame formed at the lower part of the frame such that the extending frame is able to move in a lateral direction by a slide means, the extending frame having a walk plate on the lower surface thereof,   wherein the extending frame is movable in a lateral direction by means of the slide means so that a working space is increased, thereby maximizing the work efficiency.   
     
     
         2 . The cage for construction work with an extendable function according to  claim 1 , wherein the extending frame is further provided, in one side thereof, with an auxiliary walk plate rotating through a hinge, and a wire regulating the rotational radius of the auxiliary walk plate. 
     
     
         3 . The cage for construction work with an extendable function according to  claim 1 , wherein the slide means includes:
 a fixing body assembled to the vertical bar through a bolt insertion hole and having a rolling wheel at the inner surface thereof; and   a guide rail slidably surrounding the outer surface of the rolling wheel in the form of “C” shape and assembled to a position corresponding to the fixing body outside the extending frame.   
     
     
         4 . The cage for construction work with an extendable function according to  claim 3 , wherein the fixing body is provided in a set of three bodies so that the set of three fixing bodies are assembled to the outer surface of a pair of corresponding horizontal bars. 
     
     
         5 . The cage for construction work with an extendable function according to  claim 1 , wherein the slide means includes:
 a H-shaped guide rail assembled to the lower surface of the horizontal bar; and   a moving body assembled to the upper surface of the extending frame such that an upper wheel thereof slides along the guide rail while making close contact therewith.
