Variable plate for ceiling work

Abstract

An embodiment relates to a variable plate for ceiling work, more specifically to a variable plate for ceiling work that is capable of being used to provide a safe working environment for a worker moving on the ceiling of a building or construction site. The variable plate for ceiling work includes: coupling parts separably coupled to ceiling structures; and a block module part connected between the coupling parts, extendable in shape, and having support blocks adapted to support a worker or heavy object.

What is claimed is: 
     
         1 . A variable plate for ceiling work, comprising:
 coupling parts separably coupled to ceiling structures; and   a block module part connected between the coupling parts, extendable in shape, and having support blocks adapted to support a worker or heavy object.   
     
     
         2 . The variable plate according to  claim 1 , wherein each coupling part comprises:
 a coupling part body; and   ball plungers adapted to fix the coupling part body to the support blocks.   
     
     
         3 . The variable plate according to  claim 2 , wherein the coupling part further comprises a toggle clamp adapted to fix the coupling part body to the corresponding ceiling structure. 
     
     
         4 . The variable plate according to  claim 1 , wherein the block module part further comprises an extension block located between the neighboring support blocks in such a way as to be extendable in a longitudinal direction thereof. 
     
     
         5 . The variable plate according to  claim 4 , wherein the extension block comprises:
 a first fixed case fixed to one side support block of the neighboring support blocks;   a second fixed case fixed to the other side support block of the neighboring support blocks; and   a fixing guide located between the first fixed case and the second fixed case, and   the second fixed case slides along the fixing guide in such a way as to be varied in position with respect to the first fixed case.   
     
     
         6 . The variable plate according to  claim 5 , wherein the second fixed case has a plurality of holes formed thereon, and the extension block comprises escape prevention pins coupled to the holes of the second fixed case in such a way as to fix the second fixed case and the fixing guide to each other. 
     
     
         7 . The variable plate according to  claim 5 , wherein the extension block further comprises:
 sliders located between the first fixed case and the fixing guide and between the second fixed case and the fixing guide; and   an escape prevention part located on the second fixed case in such a way as to fix the second fixed case, the fixed guide, and the sliders to one another.   
     
     
         8 . The variable plate according to  claim 1 , wherein the block module part having the support blocks in a transverse direction thereof further comprises top fasteners or underside fasteners for fixing the support blocks to one another. 
     
     
         9 . The variable plate according to  claim 1 , wherein the block module part comprises:
 a first block module having the support blocks in the transverse direction thereof and the top fasteners or underside fasteners for fixing the support blocks to one another;   a second block module located close to the first block module and having the support blocks in the transverse direction thereof and the top fasteners or underside fasteners for fixing the support blocks to one another; and   module fasteners for fixing the first block module and the second block module to each other.   
     
     
         10 . The variable plate according to  claim 1 , wherein the coupling parts are located on both sides of the block module part. 
     
     
         11 . The variable plate according to  claim 1 , wherein each coupling part comprises:
 a coupling part body;   a first ball plunger for fixing the coupling part body and the corresponding support block to each other; and   a second ball plunger for fixing the coupling part body and the corresponding ceiling structure to each other.   
     
     
         12 . The variable plate according to  claim 1 , wherein the block module part further comprises a sensing part detachably mounted on the end portions thereof in such a way as to detect whether the worker approaches the end portions thereof. 
     
     
         13 . The variable plate according to  claim 1 , wherein the block module part further comprises a lighting part located on one surface thereof.
