Fireproof precast element with securement structure

Abstract

A method of fireproofing a structural beam is provided in which a plurality of pre-cast corner elements are attached to the beam to create a plurality of cavities, each cavity being defined by two of the pre-cast elements and a portion of the beam. Concrete is poured into one of the cavities, allowed to harden, and then the beam is rotated prior to pouring concrete into another of the cavities.

1 . A method of fireproofing an I-beam having a central web connected at each end to a flange, the method comprising: 
 attaching a pre-cast corner element to each end of the flanges to form a first pair of cavities and a second pair of cavities, the first pair of cavities each being defined by at least two of the pre-cast corner elements and the central web of the beam, the second pair of cavities each being defined by at least two of the pre-cast corner elements and one of the flanges; each pre-cast corner element including a first surface substantially parallel to the central web when the pre-cast corner element is attached to the flange, each pre-cast corner element including a second surface substantially parallel to the flange when the pre-cast corner element is attached to the flange;    filling each of the first cavities with concrete such that the concrete is substantially flush with the first surfaces of the pre-cast corner elements; and    filling each of the second cavities with concrete such that the concrete is substantially flush with the second surfaces of the pre-cast corner elements.    
   
   
       2 . The method according to  claim 1 , wherein the first and second cavities are filled by pouring the concrete into the cavities.  
   
   
       3 . The method according to  claim 1 , wherein the first and second cavities are filled by spraying the concrete into the cavities.  
   
   
       4 . The method according to  claim 1 , wherein the first and second cavities are filled by troweling the concrete into the cavities.  
   
   
       5 . The method according to  claim 1 , further comprising: 
 casting the pre-cast former elements from concrete and allowing the concrete of the pre-cast corner elements to harden prior to attaching the pre-cast corner elements to the flanges.    
   
   
       6 . A method of fireproofing and I-beam having a central web connected at each end to a flange, the method comprising: 
 attaching a pre-cast corner element to each end of the flanges to form four cavities, a first two of the cavities each being defined by at least two of the pre-cast corner elements and the central web of the beam, a second two of the cavities each being defined by at least two of the pre-cast corner elements and one of the flanges;    pouring concrete into one of the cavities;    allowing the concrete poured into the one of the cavities to harden; and    rotating the beam after the concrete has hardened and prior to pouring concrete into additional cavities.    
   
   
       7 . The method according to  claim 6 , further comprising: 
 casting the pre-cast corner elements from concrete and allowing the concrete of the pre-cast corner elements to harden prior to attaching the pre-cast corner elements to the flanges.    
   
   
       8 . The method according to  claim 6 , further comprising: 
 repeating and pouring, allowing to harden, and rotating for other of the cavities until all of the cavities contain concrete.    
   
   
       9 . The method according to  claim 6 , wherein: 
 each pre-cast corner element includes a first surface substantially parallel to the central web when the pre-cast corner element is attached to the flange;    each pre-cast corner element includes a second surface substantially parallel to the flange when the pre-cast corner element is attached to the flange;    the first two of the cavities are filled such that the concrete is substantially flush with the first surfaces of the pre-cast corner elements; and    the second two of the cavities are filled such that the concrete is substantially flush with the second surfaces of the pre-cast corner elements.    
   
   
       10 . A method of fireproofing a structural beam comprising: 
 attaching a plurality of pre-cast corner elements to the beam to form a plurality of cavities, each cavity being defined by at least two of the pre-cast elements and a portion of the beam; and    filling each cavity with concrete to substantially fill the cavity.    
   
   
       11 . The method according to  claim 10 , wherein the cavities are filled by pouring the concrete into the cavities.  
   
   
       12 . The method according to  claim 10 , wherein the cavities are filled by spraying the concrete into the cavities.  
   
   
       13 . The method according to  claim 10 , wherein the cavities are filled by troweling the concrete into the cavities.  
   
   
       14 . The method according to  claim 10 , further comprising: 
 casting the pre-cast corner elements from concrete and allowing the concrete of the pre-cast corner elements to harden prior to attaching the pre-cast corner elements to the beam.    
   
   
       15 . The method according to  claim 10 , wherein the beam is an I-beam.  
   
   
       16 . A method of fireproofing a structural beam comprising: 
 attaching a plurality of pre-cast corner elements to the beam to form a plurality of cavities, each cavity being defined by at least two of the pre-cast elements and a portion of the beam;    pouring concrete into one of the cavities;    allowing the concrete poured into one of the cavities to harden; and    rotating the beam after the concrete has hardened and prior to pouring concrete into another of the cavities.    
   
   
       17 . The method according to  claim 16 , further comprising: 
 casting the pre-cast corner elements from concrete and allowing the concrete of the pre-cast corner elements to harden prior to attaching the pre-cast corner elements to the beam.
