Outer-wall construction apparatus for building

Abstract

The present invention provides an outer wall construction apparatus for a building, that is, an outer wall construction apparatus for constructing outer wall of a building having slab between floors or wall surface using stone or metal plate structures including first bracket fixed through anchor bolts inserted into the side of the slab or the wall surface along the side of the slab or the wall surface; fixation beam fixed to the first bracket, substantially vertically projected outward from the side of the slab or the wall surface; horizontal beam fixed to the fixing beam to be horizontally arranged; vertical beam fixed to outward side of the horizontal beam to be vertically arranged, having a hollow along the longitudinal direction thereof and an opening part in the shape of slit along the longitudinal direction of the outer surface thereof; second bracket comprising fixation end fixed tightly to the vertical beam along the outer surface thereof through first bolt of which the head has short side narrower than the width of the opening part and long side wider than the width of the opening part in order to be inserted into the opening part and entangled therein and first nut coupled therewith, and support end in elbow shape perpendicularly vented therefrom and projected outward from the vertical beam, wherein said plate structure, of which the upper and lower parts are supported by the support end of the second bracket constitutes outer wall of the building.

1 . An outer wall construction apparatus for building for constructing outer wall of a building having slab between floors or wall surface using stone or metal plate structures, including,
 a plurality of first brackets fixed in a horizontal row through anchor bolts inserted into the side of the slab or the wall surface, along the side of the slab or the wall surface;   a plurality of fixation beams welded and fixed one-on-one to said plurality of first brackets, substantially vertically projected outward from the side of the slab or the wall surface;   a plurality of horizontal beams that is straight or curved, welded and fixed to at least two of said fixation beams forming a horizontal row to be arranged horizontally;   a plurality of vertical beams having a hollow in the longitudinal direction thereof and an opening part in the shape of slit in the longitudinal direction of the outer surface thereof, welded and fixed to outward side of said plurality of horizontal beams to be arranged vertically in the first distance (a) and the second distance (b) with neighboring two respectively (where, b<a);   a plurality of second brackets in elbow shape comprising a fixation end securely fixed to outer surface of each of said vertical beam through first bolt of which the head has short side narrower than the width of the opening part and long side wider than the width of the opening part in order to be inserted into the opening part and entangled therein and first nut coupled therewith, and a support end perpendicularly vented therefrom and projected outward from each vertical beam; wherein,   said plate structure, of which at least four parts of upper and lower sides are supported by the support end of the second bracket, is arranged to constitute the outer wall of the building.   
   
   
       2 . An outer wall construction apparatus for building according to  claim 1 , wherein, both side ribs of said vertical beam that form the opening part are curved round to have inclination into inside of the hollow, said plate structure covers a couple of vertical beams which are placed in the first distance (a) in between. 
   
   
       3 . An outer wall construction apparatus for building according to  claim 2 , wherein, said vertical beam further includes a couple of guide ends facing each other, vented and prolonged into the hollow from end parts of both side ribs that forms said opening part, said first bolt further includes a couple of guide grooves formed on inside surface of the head toward said first nut for said guide ends to be inserted thereinto. 
   
   
       4 . An outer wall construction apparatus for building according to  claim 1 , wherein, said first nut includes a flange formed around along one end thereof to contact the fixation end of said second bracket and jagged protrusions in the shape of barbs formed along the contacting surface of the flange in the reverse direction of coupling of the first nut 
   
   
       5 . An outer wall construction apparatus for building according to  claim 4 , wherein, said vertical beam further includes a couple of guide ends vented and prolonged into the inside of the hollow from the end parts of the both side ribs forming said opening part and facing each other, said first bolt further includes a couple of guide grooves formed on inside surface of the head toward said first nut for said guide ends to be inserted thereinto. 
   
   
       6 . An outer wall construction apparatus for building according to  claim 1 , wherein, said first bolt further includes stepping part formed on inside surface of the head toward said first nut so as to be inserted into the opening part, by which said head is prevented from rotation and falling out in the left and right when inserted into the opening part and entangled therein. 
   
   
       7 . An outer wall construction apparatus for building according to  claim 6 , wherein, said vertical beam further includes a couple of guide ends vented and prolonged into the inside of the hollow from the end parts of the both side ribs forming said opening part and facing each other, said first bolt further includes a couple of guide grooves formed on inside surface of the head toward said first nut for said guide ends to be inserted thereinto.
