Concrete eave system

Abstract

A concrete eave method and system is disclosed which can be used in commercial or residential construction. The concrete eave formed by the system and method disclosed is separate from the roof truss system and, as such, the roof truss system is not subject directly to any upward forces that might be generated on the eave. The concrete eave disclosed may be formed using several concrete construction methods. The concrete eave can be formed using precast methods or poured-in-placed methods.

1 . A roofing system, comprising:
 a roof truss system; and   a concrete eave attached to a concrete sidewall, wherein the concrete eave is formed separate from the roof truss system and the roof truss system is connected to the concrete eave.   
   
   
       2 . The roofing system of  claim 1 , wherein the concrete eave is formed integral with the concrete sidewall. 
   
   
       3 . The roofing system of  claim 2 , wherein the concrete eave is precast with the concrete sidewall. 
   
   
       4 . The roofing system of  claim 3 , wherein the precast concrete eave is formed on site. 
   
   
       5 . The roofing system of  claim 3 , wherein the precast concrete eave is formed off-site. 
   
   
       6 . The roofing system of  claim 2 , wherein the concrete eave and the concrete sidewall are poured-in-place. 
   
   
       7 . A method for forming a concrete eave separate from a roof truss system, comprising:
 providing an eave form, a sidewall form and a roof truss system;   positioning the eave form and the sidewall form adjacent to one another;   pouring concrete into the eave form and the sidewall form;   allowing the concrete to cure to an appropriate stripping strength to form a concrete eave and a concrete sidewall; and   placing the roof truss system in relation to concrete eave.   
   
   
       8 . The method for forming a concrete eave of  claim 7 , further comprising:
 connecting the roof truss system to the concrete eave.   
   
   
       9 . The method for forming a concrete eave of  claim 7 , wherein the formed concrete eave has an aesthetic design. 
   
   
       10 . The method for forming a concrete eave of  claim 7 , wherein the sidewall form is a tunnel construction system and the eave form is connected to the tunnel construction system. 
   
   
       11 . The method for forming a concrete eave of  claim 7 , wherein the sidewall form is an insulated concrete form system and the eave form is connected to the insulated concrete form system. 
   
   
       12 . The method for forming a concrete eave of  claim 7 , wherein the sidewall form is a concrete block construction system and the eave form is connected to the concrete block construction system. 
   
   
       13 . The method for forming a concrete eave of  claim 7 , wherein the sidewall form is a handset form system and the eave form is connected to the handset form system. 
   
   
       14 . The method for forming a concrete eave of  claim 7 , wherein the sidewall form is a gang form system and the eave form is connected to the gang form system. 
   
   
       15 . The method for forming a concrete cave of  claim 7 , wherein the eave form includes a wood blocking. 
   
   
       16 . The method for forming a concrete eave of  claim 15 , wherein the wood blocking is used as a nailer for drip edge or for gutter installation. 
   
   
       17 . The method for forming a concrete eave of  claim 15 , wherein the wood blocking creates a truss bearing recess notch. 
   
   
       18 . The method for forming a concrete eave of  claim 7 , wherein the eave form includes a stiffener. 
   
   
       19 . The method for forming a concrete eave of  claim 8 , wherein the roof truss system is connected to the concrete eave using a through bolt and a roof strap. 
   
   
       20 . A building, comprising:
 a plurality of floor slabs;   a plurality of concrete sidewalls having formed concrete eaves formed thereon, wherein the concrete sidewalls are connected to the plurality of floor slabs; and   a roof truss system supported by the concrete sidewalls, wherein each concrete eave is a separate structure from the roof truss system.
