Description

<Desc / Clms Page number 1>

 The present invention relates to a device for protecting dwellings, technical, industrial buildings, schools and all types of construction comprising openings and accesses of all kinds.

 This device mainly protects against floods, floods, rising water, tornadoes, cyclones, storms, thunderstorms, winds and various bad weather.

 In addition, it can be used for fire protection (external to buildings) or as an anti-intrusion system.

 It is particularly suitable for risk areas: a) 1 bad weather floods: floodable areas and / or subject to muddy and / or windy invasions. b) Fires: constructions in exposed areas (forest, scrubland ...) c) Intrusions: For all types of constructions.

 Practical interests of the system: - Currently, after a meteorological alert or threat of significant rise in water levels, the occupants of housing are trying to protect themselves by installing plastic films and sandbags or by building makeshift walls , in front of entrance doors and other openings.

 - These provisions take a long time to install and are not or hardly recoverable after use. In addition, once these installations are put in place, they are not dismantled quickly for fear of the arrival of new alerts.

 - The device according to the invention makes it possible to set up a system which is assembled and disassembled quickly and as many times as necessary without damaging the walls and facades.

 The device consists of: * One or more plates with dimensions and shapes adapted to the openings to be protected that can withstand shocks of various origins and forces due to water pressure, flame resistance but also physical attack .

 '' A fixing set with several possible mounting solutions.

The plate may be rectangular, its thickness varies according to the material used with the installation of any reinforcements, its shape is variable depending on the result to be obtained.

 It can include: one or more fixed or articulated handles to facilitate handling and installation on site, a safety chain with quick coupler, seals on the two lateral sides and on its lower part. These joints can be full or hollow or hollow and inflatable-The shape and the nature of these joints are variable according to the result to be obtained, they can be, glued, inserted, clamped on the

 plate which may include grooves, folds, housings to receive them.

 Several methods are possible for fixing the plate in front of the opening to be protected. The choice is made according to the violence of the bad weather, the nature and the state of the support.

 The fixing system can be carried out by: - fixed legs (fig. 10) - sliding legs on an appropriate profile (fig. 4,5, 6,7, 8,9, 11).

- articulated stiffeners mounted on a tensioner (fig. 12).

 Figure 1 in three views shows the sheet steel plate (1) with a high and low slide (2), handle (3) and seals (11).

 Figure 2 in three views shows the plastic plate (1) with a high and low slide (2), handle (3) and seals (11). This plate is lighter than that shown in Figure 1.

 Figure 3 in three views shows the alloy plate (1) having ribs with a high and low slide (2), handle (3) and seals (11).

This light plate has the same advantages as that of FIG. 1.

 FIG. 4 represents a partial transverse section with the basic fixing using an inclined screw (5) with pitch to the left or to the right actuated by an operating button (6) acting directly on the wall and locked by a lock nut (7) . The flange (9) allows the immobilization of the tab (4) on the slide (2) with the screws (8).

 FIG. 5 represents a partial transverse section of the fixing with the use of a tilted swivel screw (30) on a swivel base (10) and operating button (6) and against nut (7). The flange (9) allows the immobilization of the tab (4) on the slide (2) with the screws (8).

 FIG. 6 represents a partial transverse section of the fixing with the use of a tilted inclined screw (30) actuated by an operating button (6) acting on a base plate (27) disposed on each side of the walls and against the nut ( 7). The flange (9) allows the immobilization of the tab (4) on the slide (2) with the screws (8).

 Figure 7 shows a partial cross section of the fixing by vertical clamping element (grasshopper) (14) fixed on a lug (4) immobilized by a flange (9) and screws (8). The grasshopper presses by pushing on a retaining stop (13) fixed on each side of the wall.

 FIG. 8 represents a partial cross-section of the fixing by clamping element with pusher (grasshopper) (15) fixed on a lug (4) immobilized by a flange (9) and screws (8). The grasshopper has at its end a ball screw (28) which

 is supported by pushing on a plate (29) which is fixed on each side of the wall.

This plate may include housings to receive the ball screw.

 Figure 9 shows a partial cross section of the fixing by horizontal clamping element (grasshopper) (17) fixed on a lug (4) immobilized by a flange (9) and screws (8).

The grasshopper may have at its end a hook (18) which grips a ring (19) by pulling.

 Figure 10 shows a partial cross section of the binding. The plate (1) may include fixing lugs (4) with screws (20) and dowels (22) or anchor bolt (22) or insert (22).

 Figure 11 shows a partial cross section of the fastener with the use of tie rod (24) secured to a lug (4) immobilized by a flange (9) and screws (8).

The tie rod is housed in an angle iron (26) fixed on each side of the wall and held by nuts (25).

 FIG. 12 shows in two views a curved plate (1), by actuating the tensioner (12) a thrust force is effected on the walls via the stiffeners (16) and the axes of articulation of the stiffeners (21 ). By tightening and loosening the tensioner, the plate is more or less curved, which allows it to be adapted to different lengths between walls.

One or more lugs (4) can be mounted in the lower part of the plate to maintain and exert a downward force by means of screws (20) and dowels (22) or anchor bolt (22) or insert (22).

Furthermore, the inclined screw (5) of Figure 4 is screwed onto the tab (4) and the swivel screw (30) with swivel base (10) of Figure 5 are screwed onto the tab (4).
