Definitions
- This invention relates to a security door and has for its object the provision of an improved such door.
- a security door whether it is a ballistic door that is a door which is designed to be resistant to bullets, shot or other high velocity projectiles, or a vandal resistant door for which a lower degree of impact resistance may be satisfactory, or a door which offers resistance to ballistic, vandal and burglar/intruder attack, requires to be both impact resistant on the one hand and of reasonably light construction on the other.
- a security door comprises first and second facing panels spaced to form a void with a sheet of reinforcing material positioned within the void.
- the sheet of reinforcing material may be positioned within the void by a structure including resilient material.
- the resilient material is positioned in a channel-shaped section.
- a second sheet of reinforcing material may be rigidly attached to the structure including the resilient material.
- the door comprises two facing panels 1 and 8, panel 1 preferably being located on the outside, or attack side of the door and panel 8 being located on the inside; these facing panels being affixed to and supported by plywood panels 2 and 7 respectively.
- the outer plywood panel 2 is further affixed to a first sheet of reinforcing material 3 to form a three part sandwich; the inner face of this sandwich being spaced from the inner face of the two part sandwich formed by panels 7 and 8 by an aluminium channel section 4.
- a second sheet of reinforcing material 6 located and maintained by resilient material 5.
- This resilient material may be made of rubber or of a similar material.
- this further sheet of reinforcing material 6 is located against the inner rear surface of the aluminium channel section 4.
- the reinforcing material may be manufactured from 6 gauge (4.88 mm thick) aluminium alloy 2014A T6 to British Standard BS1740:1987 (formerly aluminium alloy HS15 TF to British Standard BS1740:1972).
- the facing panels may be manufactured from melamine sheet as available from numerous sources of supply.
- the door In use, the door is mounted so that the outer face of the three part sandwich 1, 2 and 3, forms the outside face of the door.
- This door construction has been found to be resistant to damage from bullets and shotgun pellets or slugs to acceptable limits. Should the melamine panel 1 and plywood panel 2 be penetrated, the reinforcing sheets 3 and 6 offer good resistance to the penetration of any bullet or shotgun pellets. This resistance is particularly related to the space between these reinforcing sheets.
- Typical thicknesses for the panels and sheets and dimensions for the aluminium channel are approximately:- melamine panel 1, 1.6 mm thick, plywood panel 2, 3 mm thick, reinforcing sheets 3, at least 4.8 mm thick, aluminium channel 4, 35 mm x 25 mm x 3 mm thick, reinforcing sheets 6, at least 4.8 mm thick, plywood panel 7, 3 mm thick, and melamine panel 8, 1.6 mm thick.
- FIG 2 the construction of this door is similar to that shown in Figure 1 with components 11-18, being similar to components 1 to 8, respectively, but with the addition of a mild steel sheet positioned on the outer face of reinforcing panel 13 between that face and the plywood panel 12.
- the mild steel sheet 19 is preferably 1.6 mm thick.
- the steel reinforced front panel 19 provides satisfactory "first line” protection against vandalism and other forms of manual attack but should the front panel be penetrated, the aluminium reinforcing sheets 13 and 16 provide an enhanced degree of "second line” protection.
Abstract
A security door comprises first and second facing panels 1,8 spaced to form a void with a sheet of reinforcing material 3 positioned within the void by a resilient material 5 held in a channel shaped section 4. A second sheet of reinforcing material 6 is rigidly attached to the channel shaped section 4.
Description
- This invention relates to a security door and has for its object the provision of an improved such door.
- A security door whether it is a ballistic door, that is a door which is designed to be resistant to bullets, shot or other high velocity projectiles, or a vandal resistant door for which a lower degree of impact resistance may be satisfactory, or a door which offers resistance to ballistic, vandal and burglar/intruder attack, requires to be both impact resistant on the one hand and of reasonably light construction on the other.
- According to the present invention, a security door comprises first and second facing panels spaced to form a void with a sheet of reinforcing material positioned within the void.
- The sheet of reinforcing material may be positioned within the void by a structure including resilient material.
- Preferably the resilient material is positioned in a channel-shaped section.
- A second sheet of reinforcing material may be rigidly attached to the structure including the resilient material.
- Two constructions of door in accordance with the invention will now be described by way of example with reference to the accompanying drawings in which:-
- Figure 1 is a partial sectional view of a ballistic door, and
- Figure 2 shows a similar view of an improved ballistic, burglar and vandal resistant door, the improvement being embodied in the addition of a sheet of steel to an outermost face of an outer sheet of reinforcing material thus providing resistance for external use.
- Referring to Figure 1, the door comprises two facing
panels panel 1 preferably being located on the outside, or attack side of the door andpanel 8 being located on the inside; these facing panels being affixed to and supported byplywood panels outer plywood panel 2 is further affixed to a first sheet of reinforcingmaterial 3 to form a three part sandwich; the inner face of this sandwich being spaced from the inner face of the two part sandwich formed bypanels material 6 located and maintained byresilient material 5. This resilient material may be made of rubber or of a similar material. In the arrangement shown, this further sheet of reinforcingmaterial 6 is located against the inner rear surface of the aluminium channel section 4. Various methods may be employed to assemble the panels, a preferred method being to join theplywood panels material resilient material 5 by means of screws or other mechanical fastening means and to secure the facingpanels plywood panels - In use, the door is mounted so that the outer face of the three
part sandwich melamine panel 1 andplywood panel 2 be penetrated, the reinforcingsheets - Typical thicknesses for the panels and sheets and dimensions for the aluminium channel are approximately:-
melamine panel 1, 1.6 mm thick,
plywood panel
reinforcingsheets 3, at least 4.8 mm thick,
aluminium channel 4, 35 mm x 25 mm x 3 mm thick,
reinforcingsheets 6, at least 4.8 mm thick,
plywood panel
melamine panel 8, 1.6 mm thick. - Referring to Figure 2 the construction of this door is similar to that shown in Figure 1 with components 11-18, being similar to
components 1 to 8, respectively, but with the addition of a mild steel sheet positioned on the outer face of reinforcingpanel 13 between that face and theplywood panel 12. Such an arrangement offers enhanced resistance against vandal and other physical manual attack where the door forms an external barrier. Themild steel sheet 19 is preferably 1.6 mm thick. - In use, the steel reinforced
front panel 19 provides satisfactory "first line" protection against vandalism and other forms of manual attack but should the front panel be penetrated, thealuminium reinforcing sheets
