A training door, door frame, and system are disclosed that allow first responders to train on breaking open locked doors. The door frame provides a channel for a replaceable rod or bar formed of a door material, so that during training, while the rod or bar may be disfigured by repeated training exercises, the remainder of the door and frame remain intact. In this manner, only the rod or bar may need to be replaced after repeated training, rather than the entire door or frame.

A door frame component is provided. The door frame includes: a front wall, a rear wall, an outer wall and an inner wall; a length of the front wall being substantially the same as a distance between the inner wall and the outer wall; an internal cavity at least partially defined by space between the inner wall and outer wall; and opposing first and second gripping sections defined in the internal cavity at least partially by first and second internal flanges in the internal cavity. The frame has sufficient structural integrity such that when the frame is cut height wise between the first and second internal flanges into front and rear sections, the front section can support a door on its own without the rear section.

[Object] To provide a door frame structure and a method for mounting the door frame structure which improve rigidity, prevent deformation that is caused by relative story displacement of a building in the event of an earthquake, and enable easy mounting.[Solution Means] A door frame structure 1 is indirectly mounted to a wall surface 4 via mounting angles 11 fixed to the first reinforcing members 9. Therefore, the door frame structure 1 does not follow relative story displacement of the wall surface 4 caused, by lateral vibration in the event of an earthquake, so that deformation of the door frame structure 1 is minimized, and a door 31 can be opened and closed even in an emergency.
摘要:
A door frame including an inside steel panel having a first inner surface and a first outer surface, and a C-shaped section with a first portion of the C-shaped section extending parallel to the inner surface of the inside steel panel; an outside steel panel having a second inner surface and a second outer surface, and a U-shaped section with a second portion of the C-shaped section extending perpendicular to the second inner surface of the outside steel panel; a first insulating material interposed between the first portion of the C-shaped section of the inside steel panel and the second inner surface of the outside steel panel to thermally isolate the inside steel panel and the outside steel panel from each other, and said inside steel panel and outside steel panel being secured together to form a thermal break system.

A plastic thermal barrier connects an inner shell and an outer shell of a window frame or a door frame. The thermal barrier includes a first part that is provided with a component for connecting it to an inner shell and an outer shell. The thermal barrier further includes a second part, whereby these parts are connected to one another in a hinged way by means of a film hinge and are provided with mutually complementary elements of a snap connector configured to fasten the two parts together.
摘要:
A natural thermal cut window and door frame (1) comprising a first section bar (2; 51), suitable to be fixed to the perimetric wall delimiting a room of a building, and a second section bar (3; 52) cooperating with said first section bar (2) in order to hermetically close the room itself, a pair of front panels supported by the second section bar (3), suitable to form the interface between the outer environment and the inner environment of the building. In particular, each of the aforesaid section bars (2, 3; 51) is composed of at least two shaped portions (4, 5; 53, 54) distinct and independent each other, connected each other through union means (6), in order to define between the shaped portions (4, 5; 53, 54) a thermal insulation slot (7) suitable to allow air circulation from/to the outer environment to/from the inner environment, and provided with reinforcement means (8) suitable to assure structural rigidity.
摘要:
A steel door system is disclosed. The steel door system includes a steel door, a steel door jamb, and a steel window frame. Each component of the steel door system is made with minimal materials and joints. The minimal materials and joints greatly reduce the risk of failure of the final steel door system. The steel door is made of steel door stiles and rails that are each formed of a single piece of sheet metal. The steel door jamb is made of three pieces of sheet metal, and the steel window frame is made of three pieces of sheet metal. These components are coupled together to create the finalized steel door system.
摘要:
An apparatus, system, and method are disclosed for preventing the intrusion of poured concrete into the space defined by a window buck installed between concrete forms. The apparatus, system, and method include a window buck panel incorporating a concrete exclusion barrier comprising a protrusion formed on the body of the window buck panel; a flange affixed to an attachment leg of the window buck panel; or an appropriately shaped leg of a window buck panel. The concrete retention barrier is configured to contact a concrete form under pressure and remain in contact as the form alters shape from the weight of infused concrete. By preventing fluid concrete from entering a defined window cavity during formation of a concrete wall the apparatus, system, and method described eliminate the need to remove hardened concrete from the interior of the cavity before window installation. Use of certain embodiments of the described invention saves time and effort in preparing the window cavity for window installation and also preserves the cleanliness and precise configuration of the window installation surface.
摘要:
A fire resistant, elevator hatchway door entrance for wall openings up to and including 10 feet in height, including first and second side jambs and a head jamb. Each side jamb includes a pair of upstanding, oppositely facing, metallic channel members dimensioned and coupled together to define both a structural box beam and a pocket for receiving the wall which defines the opening. The bight and one leg portion of one channel member define the jamb depth and reveal, respectively, of the side jamb, and the bight of the other channel member receives and shields an asociated J-strut at the wall-entrance interface. The remaining leg portion of the one channel member may cooperate with a member disposed on the trailing edge of the associated door panel to define a flame shield and a mechanical limit for preventing undue separation of the door panel from the side jamb.
