Description:

BACKGROUND

This invention relates to in-residence storm shelters. The need is addressed by the Federal Emergency Management Agency (FEMA) as well as various universities and groups. The common recommended method of using conventional building materials to achieve the desired protection level is by far exceeded with the present invention. The present invention will be packaged as a kit in which the components can be easily handled by 2 people and assembled prior to pumping concrete into the formed voids, (floor, wall and ceiling cavities) rather than the use of common building materials.

SUMMARY OF INVENTION

It is an object of the present invention to provide a structure to protect the occupants of the structure from debris generated by storms (I.E. tornadoes, hurricanes, etc.) The intent is to provide a structure that can be assembled in a desired location according to a prescribed method, and then reinforced with concrete fill which upon curing will substantially add to the strength of the structure and also increase the structure's weight, vastly increasing its stability. The structure size can be increased by increasing the quantity of identical floor plates, top plates, wall plates, ceiling plates, etc. . . . described in the drawings. The fasteners discussed here-in are the preferred choice although alternate bolt and nut combinations and/or drilling and tapping of holes will accomplish the same result.

DETAILED DESCRIPTION OF DRAWINGS

FIG. 1 Orthographic Door End View of Structure:

Door (19) is hinge mounted from corner structure (5). Door (19) is provided with ventilation slots and baffle plates (21 &22) to prevent direct entry of debris into occupant chamber.

FIG. 2 Orthographic Side View of Structure:

Corner structure (5) is mounted on base plate weldments (1 &3) utilizing self threading cap screws (25). Spacer pads (4) are provided to elevate outside corner of plates to prevent interference with radius formed in bent plates. Braces (6 &7) are provided to align and hold parts in desired location and secured with self threading cap screws (25). Top plates (17 &18) are mounted on structure utilizing self threading cap screws (25). Top plate (17) and top plate (18) are joined to one another utilizing self threading cap screws (25) on lower surface before ceiling panels (23) are installed.

FIG. 3 Orthographic Rear View of Structure:

Corners (5) are held in proper alignment utilizing braces (6 &7) and secured to base plates (1 &3) utilizing self threading cap screws (25). End plate (14) is fastened to corners (5), base plate (3) and top plate (17) utilizing self threading cap screws (25). End plate (14) is provided with ventilation slots and baffle plates (21 &22) to prevent direct entry of debris into occupant chamber.

FIG. 4 Orthographic Top View of Structure:

Top plates (17 &18) fasten to each other utilizing self threading cap screws (25) and fasten to structure utilizing self threading cap screws (25). Spacer pads (4) are utilized to prevent interference of corners of plates with radius formed in bent plates.

FIG. 5 Section View Taken at Cutting Plane 5-5 (See FIG. 4):

Ceiling plates (23) are fastened to corners (5), wall interior panels (11) and top plates (17 &18) utilizing self threading cap screws (25). Clearance holes are provided in outside wall plates (12 &14) and inside plates (11 &15) to accept tension bolt/nut assembly (13) to minimize plate swellage during concrete filling.

FIG. 6 Section View Taken at Cutting Plane 6-6 (See FIG. 5):

Floor plates (6) are secured on base plates (1, 2 &3), interior wall plates (11 &15) and corner weldments (5) utilizing self threading cap screws (25). % turn plugs (20) are provided for filling empty cavities with concrete upon completion of assembly per FIG. 12.

FIG. 7 Isometric View—Partially Assembled (Step 1):

Floor plate sub-weldments (1, 2 &3) join to one another utilizing self threading cap screws (25). Spacer pads (4) are provided to elevate corners of mating plates to prevent interference with radius formed in bent plates.

FIG. 8 Isometric View—Partially Assembled (Step 2):

Added components—corner sub-weldments (5), columns (8), braces (6 &7), doorway ceiling plate (10), and doorway end plates (24) are fastened utilizing self threading cap screws (25).

FIG. 9 Isometric View—Partially Assembled (Step 3):

Added components—interior wall plates (11, 12 &15), exterior wall plates (12 &14) and floor plates (9 &10) are fastened utilizing self threading cap screws (25). Door stop bars (16) are attached to corners (5) preferably by welding, Clearance holes are provided in outside wall plates (12 &14) and inside plates (11 &15) to accept tension bolt/nut assembly (13) to minimize plate swellage during concrete filling.

FIG. 10 Isometric View—Partially Assembled (Step 4):

Door (19) is hinge mounted on corner (5). Top plate sub-weldments (17 &18) are fastened to each other and into structure utilizing self threading cap screws (25).

FIG. 11 Isometric View—Partially Assembled (Illustration Only):

Top plates (17 &18) are omitted in this view for clarity. Ceiling plates (23) are fastened into structure utilizing self threading cap screws (25)

FIG. 12 Isometric View—Completely Assembled:

Structure at this stage is ready for concrete filling (preferably utilizing a concrete pumping machine and a concrete vibrator). Cavities to be filled would be filled in sequence as marked (E.I.—Both plugs marked “A” would be removed until concrete appears fully at both openings, then stop filling and replace plugs. Proceed to both plugs marked “B” and repeat sequence for all plugs until all cavities are filled.
