Abstract
Systems and methods for securely attaching a screen or mesh to a pre-stressed or precast concrete wall panel are provided. A screen or mesh is embedded in a concrete form when the concrete form is poured. Portions of the concrete form can be stripped and the wall panel can be easily removed from the form without binding on the form itself and without requiring removal of the portion of the form which creates the window opening.
Claims22
A method for creating a screened opening in a concrete form comprising:
- embedding a mesh in a concrete form when the concrete form is poured by:
- creating a window form in a portion of the concrete form, the window form including a base and a removable cap;
- placing a mesh at the base of the window form, where outer edges of the mesh extend beyond the base of the window form;
- securing the removable cap to the base of the window form;
- and
- creating a seal between the base of the window form and the removable cap, where the base of the window form and the removable cap have opposing slots that creates a seal against the mesh.
A method for creating a screened opening in a concrete form comprising:
- embedding a mesh in a concrete form when the concrete form is poured by:
- creating a window form in a portion of the concrete form, the window form including a base and a removable cap;
- placing a mesh at the base of the window form, where outer edges of the mesh extend beyond the base of the window form;
- securing the removable cap to the base of the window form;
- and
- creating a seal between the base of the window form and the removable cap using slots on at least one of the base and the removable cap for engaging and sealing against the mesh.
A form for a concrete wall panel comprising:
- a series of form boundary walls for accepting concrete and forming the outer boundaries of the wall panel;
- and
- at least one window form for forming at least one window opening in the wall panel comprising a base and a removable cap, mesh being on the base of the window form with outer edges of the mesh extending beyond the base of the window form for coverage by and being embedded in the concrete, the removable cap being secured to the base of the window form, a sealing assembly creating a seal between the base of the window form and the removable cap for preventing entry of the concrete therethrough, in which at least one of the base and the removable cap has slots for engaging and scaling against the mesh.
A system for creating a screened opening when concrete is poured comprising:
- a window form having a base and a removable cap;
- a mesh at the base of the window form, where outer edges of the mesh extend beyond the base of the window form;
- the removable cap being secured to the base of the window form;
- and
- a sealing assembly creating a seal between the base of the window form and the removable cap having slots in at least one of the base and removable cap for engaging and sealing against the mesh.
A concrete wall panel having a length, height and thickness, the wall panel having at least one window opening comprising mesh material having outer edges embedded into the wall panel, and at least one removable window form, the at least one window form comprising a base and a removable cap, the mesh being on the base of said window form with outer edges of the mesh extending beyond the base of the window form covered by and being embedded in concrete, the removable cap being secured to the base of the window form, a sealing assembly creating a seal between the base of the window form and the removable cap having slots in at least one of the base and the removable cap for engaging and sealing against the mesh.
