Earthquake Proof Wall Panels

Abstract

A building structure is formed of large, pre-formed or pre-cast structural slabs i.e., pre-cast wall panels ( 1 ) that contain a plurality of horizontally extending reinforcing members ( 2 ) that protrude out of the wall panel at its two opposite ends by a predetermined length. The pre-cast wall panel ( 1 ) further consists of a plurality of recesses ( 3 ) and projecting recess keys ( 4 ). The pre-cast wall panels ( 1 ) are placed facing each other or orthogonal to each other each such that when an imaginary line from the ends of the wall panels that are oriented towards each other, projects from the projecting reinforcing members ( 2 ), of each respective reinforced concrete pre-cast wall panel ( 1 ), these lines intersect at a common point. The gap in between the wall panels provides a means of connecting the individual pre-cast wall panels by means of a wet joint ( 11 a, 11 b, 11 c, 11 d ). The wet joints ( 11 b, 11 c, 11 d ) can then act as columns 5 of a building structure. The construction of the pre-cast wall panels ( 1 ) consisting of a plurality of recesses ( 3 ) and recess key projections ( 4 ) together with the reinforcing members ( 2 ) serve to provide structural stability and robustness to the building structure. The recesses ( 3 ), recess key projections ( 4 ) in addition to the extending reinforcing members ( 2 ) more particularly serve to transfer the loads of the pre-cast wall panels ( 1 ) directly to the columns ( 5 ) of a building structure.

1 . A reinforced concrete pre-cast wall panel ( 1 ) which forms partition compartments of a building, that are further designed as structural elements to be integrated with a cast in situ building structure frame wherein the reinforced concrete pre-cast wall panels that is capable of increasing the stability and robustness of a building structure at a low cost and hence provide a measure of earth-quake proofing apart from enabling a building structure to be built using a modular approach and allowing said building to be built in a quick and efficient manner;
 characterized in that said pre-cast wall panel has a plurality of recesses ( 3 ) and recess key projections ( 4 ) that are alternately staggered and further distributed along its entire vertical length at both its opposing sides, thereby aiding said wall panels in transferring their loads to the columns of the building structure and thus providing for the structural stability and robustness of the building structure.   
     
     
         2 . A reinforced concrete pre-cast wall panel as in  claim 1 , wherein said pre-cast wall panel contains a plurality of vertically equidistant reinforcing members ( 2 ) extending laterally through the entire width of said pre-cast wall panel and further protruding at both ends by a pre-defined length. 
     
     
         3 . A reinforced concrete pre-cast wall panel as in  claim 2 , wherein the reinforcing members ( 2 ) protrude or extend outwards from the centre of the said recesses at both the opposing sides of said reinforced concrete pre-cast wall panel. 
     
     
         4 . A reinforced concrete pre-cast wall panel as in  claim 1 , wherein said pre-cast wall panels are used as structural elements to be integrated with a cast in situ building structure characterized in that two identical adjoining wall panels ( 1 ) are joined together side by side to form a space that is filled with concrete thus forming a wet joint ( 11   a ). 
     
     
         5 . A reinforced concrete pre-cast wall panel ( 1 ) as in  claim 1 , wherein said pre-cast wall panels are used as structural elements to be integrated with a cast in situ building structure characterized in that two identical wall panels ( 1 ) are joined together at the sides to a form a space that is filled with concrete forming a “L:” shaped wet joint ( 11   d ) that can act as a column ( 5 ) of a building structure. 
     
     
         6 . A reinforced concrete pre-cast wall panel as in  claim 1 , wherein said pre-cast wall panels are used as structural elements to be integrated with a cast I situ building structure characterized in that three identical wall panels ( 1 ) are joined together to form a space that is filled with concrete forming a “T” shaped wet joint ( 11   b ) that can act as a column ( 5 ) of a building structure. 
     
     
         7 . A reinforced concrete pre-cast wall panel as in  claim 1 , wherein said pre-cast wall panels are used as structural elements to be integrated with a cast in situ building structure characterized in that four identical wall panels ( 1 ) are joined together to form a space that is filled with concrete forming a “X” shaped wet joint ( 11   d ) that can act as a column ( 5 ) of a building structure. 
     
     
         8 . A structural unit for a building comprising a reinforced concrete pre-cast wall panel as defined in  claim 1 . 
     
     
         9 . A structural unit according to  claim 8 , further integrated with lateral beams ( 8 ,  9 ), floor slabs ( 7 ) and bedding structures ( 10 ), wherein the reinforced concrete pre-cast wall-panels ( 1 ) are erected into box compartment modules with formworks bolted into position for the subsequent casting of in situ columns ( 5 ).
