专利汇可以提供Method for making cast-in-place concrete structures专利检索，专利查询，专利分析的服务。并且A method for making a cast-in-place concrete structure comprises the steps of forming an arrangement of concrete forms; placing a plurality of void creating devices within the confines of and spaced from the concrete forms, each of the void creating devices being an elongated hollow member made of frangible material, and having at least one opposed pair of projections, with the respective projections of adjacent devices abutting one another in order to enable internal communication between said devices, and with the ends of the devices and the non-abutting projections thereof extending to the periphery of the concrete forms; and pouring uncured concrete into the spaces in and around and in intimate contact with the void creating devices, and allowing the concrete to cure. Subsequently, the frangible ends and exposed projections of the void creating devices may be knocked out in order to provide access into the labyrinth of passageways defined by the hollow devices within the interior of the composite concrete structure. The void creating devices are preferably made of an insulating material, thereby resulting in a one-process system for achieving a one layer, composite, self-insulated concrete construction unit, and which enables the unit to be integrally finished on both sides.，下面是Method for making cast-in-place concrete structures专利的具体信息内容。
1. A method for making a cast-in-place concrete structure comprising the steps of: forming an arrangement of concrete forms to define the periphery of the concrete structure; placing a plurality of void creating devices within the confines of and spaced from said concrete forms, each device being an elongated hollow member made of frangible material, and having at least one opposed pair of projections intermediate its length, with the respective projections of adjacent devices abutting one another in order to enable communication between said devices, and with the ends of the devices and the nonabutting projections thereof extending to the periphery of said concrete forms; and forming the concrete structure by pouring uncured concrete into the space defined between said concrete forms and the void creating devices thereby embedding the void creating devices therein except for said ends of the devices and the nonabutting projections thereof, and allowing the concRete to cure.
2. A method for making a cast-in-place concrete structure as in claim 1 further including the step of knocking out an exposed end of a void creating device, and pouring uncured concrete into the hollow void creating device and allowing said concrete to cure in order to define a concrete beam within said concrete structure.
3. A method for making a cast-in-place concrete structure as in claim 1 wherein each void creating device includes two opposed sets of projections extending orthagonal to the longitudinal axis thereof, with one set of opposed projections extending parallel to the plane of the resulting concrete structure, and the second set of projections extending generally orthagonal to the plane thereof, and including the further step of removing a portion of the wall surface of said concrete structure in the vicinity of one of said second set of projections in order to provide access to the labyrinth of passageways within said concrete structure through the wall thereof.
4. A method for making a cast-in-place concrete structure as in claim 1 wherein each set of void creating devices is internally compartmentalized by means of internal baffles, and further including the step of creating a through conduit extending transverse to the axes of said void creating devices by knocking out an exposed, non-abutting projection thereof, as well as the embedded projections in alignment with said non-abutting projection, and filling said through passageway with uncured concrete, and allowing said concrete to cure in order to form an internal concrete beam within said concrete structure.
5. A method for making a cast-in-place concrete structure as in claim 1 further including the step of placing elongated reinforcing bars along the length of the devices within the concrete forms prior to the step of pouring the uncured concrete.
6. A method for making a cast-in-place concrete structure as in claim 1 further including the step of placing reinforcing bars transverse to the longitudinal axes of said devices within the concrete forms prior to the step of pouring the uncured concrete.
7. A method for making a cast-in-place concrete structure as in claim 1 wherein said arrangement of concrete forms includes two-spaced concrete forms which are maintained in spaced relationship by wall tires having holes therein, and the further step of inserting reinforcing bars through the holes in the wall ties prior to the step of pouring the uncured concrete.
8. A method for making a cast-in-place concrete structure as in claim 1 including the additional step of removing the concrete forms, and knocking out the exposed frangible projections of the void creating devices in order to provide access to the labyrinth of passageways within said concrete structure.
9. A method for making a cast-in-place concrete structure as in claim 8 further including the step of ducting service lines through said labyrinth of passageways.
10. A method for making a cast-in-place concrete structure as in claim 1 wherein each void creating device includes a plurality of projections, disposed parallel to and transverse to the wall of the concrete structure, and including the further step of removing cured concrete in the vicinity of one of said projections in order to provide communication through the wall surface of the concrete structure to the labyrinth of passageways within the concrete structure.
11. A method for making a cast-in-place concrete structure as in claim 10 including the further step of knocking out the exposed ends of the devices and the nonabutting projections thereof thereby providing three dimensional access to the labyrinth of passageways within the concrete structure.
12. A method for making a cast-in-place concrete structure as in claim 11 further including the step of ducting service lines through said labyrinth of passageways.
13. A method for making a cast-in-place concrete structure comprising the steps of: forming an arrangement of concrete formS to define the periphery of the concrete structure; placing a plurality of insulating void creating devices within the confines of and spaced from said concrete forms, each device being an elongated hollow member made of an insulative, frangible material, and having at least one opposed pair of projections intermediate its length, with the respective projections of adjacent devices abutting one another in order to enable communication between said devices, and with the ends of the devices and the non-abutting projections thereof extending to the periphery of said concrete forms; forming the concrete structure by pouring uncured concrete into the space defined between said concrete forms and the void creating devices so as to embed the void creating devices therein except for said ends of the devices and the nonabutting projections thereof, and allowing the concrete to be cured; and removing the concrete forms, and knocking out the exposed frangible projections of the void creating devices in order to provide access to the labyrinth of the passageways within said concrete structure.
14. A method for making a cast-in-place concrete structure as in claim 13 further including the step of ducting service lines through said labyrinths of passageways.
15. A method for making a cast-in-place concrete structure as in claim 13 wherein each void creating device includes a plurality of projections, disposed parallel to and transverse to the wall of the concrete structure, and including the further step of removing cured concrete in the vicinity of one of said projections in order to provide communication through the wall surface of the concrete structure to the labyrinth of passageways within the concrete structure.
16. A method for making a cast-in-place concrete structure as in claim 15 including the further step of knocking out the exposed ends of the devices and the nonabutting projections thereof thereby providing three dimensional access to the labyrinth of passageways within the concrete structure.
17. A method for making a cast-in-place concrete structure as in claim 16 further including the step of ducting service lines through said labyrinth of passageways.
