Precast structural element and method for connecting the precast structural element to each other

Abstract

The precast structural element is made by a method including preparing one or more layers of plurality of horizontal and vertical reinforcement bars. The method further includes fixing a plurality of hollow tubes to the layers at predefined locations by holding means. Specifically, the hollow tubes are provided with openings at predefined locations. The hollow tubes are characterized by having any one of plurality of protrusions, plurality of corrugation, plurality of ribs, plurality of serrations and combination thereof, on internal and external surfaces. The method further includes providing a means to fill or discharge adhesive in the hollow tubes and pouring concrete to create a precast structural element.

1 . A precast structural element capable of connecting with each, the precast structural element made by a method comprising:
 preparing one or more layers of plurality of horizontal and vertical reinforcement bars;   fixing plurality of hollow tubes to the layers at predefined locations by holding means, the hollow tubes further provided with openings at predefined locations, the hollow tubes characterized by having any one of plurality of protrusions, plurality of corrugation, plurality of ribs, plurality of serrations and combination thereof, on internal and external surfaces,   providing a means to fill or discharge adhesive in the hollow tubes; and pouring concrete to create a precast structural element.   
     
     
         2 . The precast structural element as claimed in  claim 1 , wherein the hollow tubes further comprises means for preventing a load transferring element to rest at bottom of the hollow tube. 
     
     
         3 . The precast structural element as claimed in  claim 1 , wherein supplementary reinforcement bars are configured in the region of horizontal and vertical reinforcement bars. 
     
     
         4 . The precast structural element as claimed in  claim 1 , wherein at least one in the pair of opposing hollow tubes further comprises a joint assembly connected thereto, wherein the joint assembly comprises:
 a T shaped connecting member for accessing the load transferring element;   a reducing shaped member with one end having greater diameter than the other end, the reducing shaped member connected to T shaped connecter at larger diameter; and   a connecting means for connecting to any one of the T shaped connecting member, the reducing shaped member and the hollow tube.   
     
     
         5 . A method for connecting precast structural elements, the method comprising:
 bringing together two precast structural elements close to each other; placing load transferring element in the hollow tubes of the first precast structural element, characterized in that the load transferring element is configured with markings thereon at predetermined locations;   erecting the second precast structural element next to the first precast structural element;   aligning the center lines of the openings of the hollow tubes in the second precast structural element with the openings of the hollow tubes in the first precast structural element;   sliding the load transferring element into the second precast structural element till the desired marking; and   filling an adhesive in the openings and gap between the two precast structural elements.   
     
     
         6 . The method as claimed in  claim 5 , wherein the sliding the load transferring element is by any one of the electrical machine with drive mechanism, pulling the bar via a wire from first element, magnetic means and manual.
