FR2730001A1 - Removable sealed panels for protection of building openings during flooding - Google Patents

Abstract

The protection system for building door or window openings used in case of flooding is composed of removable sealed panels (1). The panels are made from galvanised sheet metal (2) and folded into a U at top and bottom which gives them a rigidity and enables sealing joints to be inserted. The panel lengths are reinforced by an angle iron (7) which is welded step by step along the length. The rigidity of the lateral fixings is provided by reinforcing plates (3) held in place by rivets (4) Lateral holes (5) allow fixing to posts for connecting to the ground or between panels. The panels are installed by pegs, long screws and wing nuts which enable controlling the clamping of joints. The pegs are protected during periods of non use.

Description

DESCRIPTION
The present invention relates to a type of cofferdam. modular. removable, Nesting
for storage, economical and quick to install. They are intended for the protection of the openings of all kinds of buildings during floods. flash and temporary flooding.

Up to now in the event of flash floods, the random protection of the bays of the buildings of
all natures are made by parpins, boards, sandbags, etc.

Put in a hurry the result is very poor, the places are flooded with water and
mud. The damage is considerable and traumatic.

My invention consists of removable and modular waterproof cofferdam panels,
standard or custom built -
Installed first on the racks, then dismantled and stored, they will be ready for
be set up in a few minutes at the time of floods. This installation will avoid
brutal and massive return of water and mud to the ground floors and cellars.

It will be more effective if it is collective protection, for example in
a sloping street when torrents of goats break out
If the building has good relatively waterproof foundations, by adding to the cellar or under crawl space a manual or electric pumping that the guarantee against water can be
relatively prolonged.

People protect themselves against theft, fire, why wouldn't they protect themselves against
rising waters
THE POSE OF USE N CASE OF FLOODS comes down to:
Remove the small ankle protection screws from the legs and the floor. Present the panel in its place by tilting it very slightly, take the screws dc 8/60 from & 60 with their nuts
screw them into the dowels. tighten the wing nuts Parallel to the bolts
are to be put in place. This stemm allows the tightness control of the joints.

THE SYSTEM CONSISTS OF RIGID AND SEALED PANELS ADAPTING TO
ALMOST ALL POSTING CASES.

For small openings such as air vents and ventilation hatches the panels
will be made on demand. in small series or on measure.

For medium-sized bays, standard elements will allow installation with
a maximum tolerance in width or a cut in place
Entrances of large widths such as those of garages, customs, will be treated with specific reinforced panels
The waterproof panels provide protection from outside to
inside the building than vice versa - This property provides protection in the event of leaks
of pipes or tanks
The height of the stackable panels is not of crucial importance, however for
allow climbing according to the height of water, the choice was fixed at 0, D4 and 0.46 M. These two dimensions make it possible to make the nesting panels for storage.

The material of the panels must above all be economical. in this case ct: St la tôle
of galvanized steel which presents the best quality / price by its resistance in lumps and its
ease of machining.

The bolts are preferably made of stainless steel and the dowels are of brass to avoid that at the time of the emergency installation there is no problem of seizing and rusting.

STANDARD PANEL
Figure I plate I shows an extremxte of the panel (1) made of galvanized sheet 20 '10th cut and folded (2) in U at the bottom and at the top. This economical folding gives rigidity and allows the bonding of seals for the floor and the joint
This simple form of the panel produced in the press for small series, will allow in case of generalized demand, the elaboration on bench of long lengths of profiles (ex 6 M).

They will be cut with a chainsaw according to the size requested for the panel.

In this case, the tailoring can be done on site, only two operations being necessary, the flow and the drilling.

Depending on the length of the panel, a reinforcement angle (7) is welded step by step. Its position is determined by H / 2-20 (due to the pull-out arrangement).

The rigidity at the side fixings is ensured by 40/8 flat iron reinforcements (3), held in place by two rivets (4).

The lateral holes (5) allow the fixing to the legs while those of the heels (6) are used for the connection to the ground or that of the panels between them -
CONTACT SURFACES (8)
On the shell they should be relatively flat to ensure good crushing of the joints. Any anomaly in the installation plan must be rectified beforehand.

BINDINGS
By dowels (9), long hexagon screws (10) and wing nuts (11) are adopted so that after the primary installation, installation and removal can be carried out quickly by a non-professional with one or two keys 13 and a large screwdriver. The brass plugs and the stainless steel bolts help to prevent rust problems.

 The installer will ensure the reliability of the support to receive the pegs. On the contrary, a larger hole will receive a dowel sealed on demand.

The anchors (9) are protected in place by short countersunk (12) or domed (13) head screws according to Figs. 8 and 9 P1. 4. They will be lightly greased before their installation. During storage bolts and screws will be held in place by their nuts
JOINTS
Made of flexible foam based on rubber or neoprene with good resistance over time. (14V) for vertical and (14T) for transverse.

Sections 15i15 or 20/20 with a self-adhesive side are generally suitable.

Their positions are determined in the attached figures. The transverse joints are cut after installation with an overhang of 10 m / m. For corner fittings they overlap by a third of their width, at the end they are also cut longer.

Before bonding the joints, degrease and frost the surfaces.

When crushed, the thickness of the joint must be approximately 3 to 4 m / m.

POSTING POST
For the start of the installation, the base panel and its elements, without joints, are fitted on wooden blocks of 3m / m to facilitate drilling and drilling tracing.

This study considers the most classic cases. The precisions and details are given by the attached figures.

EXTERIOR OR INTERIOR LAYING
Preferably placed outside, the panels can be installed indoors. (e.g. in the case of an EDF transformer where the door opens to the outside).

The panels are installed so as not to interfere with the fittings in place.

LAYING PART LOW 1) On hard ground (19! Or threshold (18)
According to Fig 3 PL. 2 Checking identical to fig. 2 (9 + 10 + 11). A joint (14T) ensures watertightness and a joint tale (15) avoids excessive heel deformation.

In case of sloping supports like those of the windows, small wooden blocks will be placed in front of the fixings to replace the counter joints.

2) On the threshold (18) or against the step (20)
According to Fig. 4 PL. 3
Complementary flat iron sections folded square (21), bolted (28) to the heel and ankles according to fig 2 ensure the maintenance of the panel in the lower part.

3) Installation with weak or oblique against step (20)
According to Fig. 5 PI. 3
An angle (22) of the width of the table (17) with welded legs (23), is fixed on the threshold by dowels (9 + 10 and 11). The panel is bolted to the angle iron with the interposition of two joints (14T)
INSTALLATION ACCORDING TO LEGS (16) 1) Wall-mounted
According to Fig 2 PL. 2
The minimum overlap is determined by the standards for fitting the anchors. They are 2 to 3 per panel dimension.

The cover can be cut for example to allow the passage of the hinges of the shutters. If the position of the fasteners is changed, it is necessary to ensure that the seals (14V) are properly crushed. 2) Panel installation (17) or tunnel installation According to Fi. 6 P1 4.

For this type of installation, an angle iron (25) is fixed by dowels (9-10 and 11) on each table, the length of which will be determined by the desired protection height. This angle iron has a small flat iron 20 / 5/40 (26) forming a heel, to receive the joint return.

2 seals (14V) are glued on the wall side angle iron (24) and 2 others (14V) on the panel
The panel fixing bolts and the angle plugs will not be screwed a. screw 3) Mixed installation
The arrangements defined in 1 and 2 allow installation in a table on one side and on the other as a surface.

PROTECTION HEIGHT
Fig 7 PI 4 shows the arrangements to be made for the superposition of two panels
The joints (14T) and (15) will be glued to the heel of the upper panel. The first panel can seal, the second the protection of transient waves, while the third is to be seen ...

 There are the risks of iiiitlltrations and those of return by the sewer A valve and a rendering of the foundations can between envisaged. (A dwelling is not conceived like a ship).

DEVIATION DAM AND PIPING
Mounted on the sealed posts (29) or plates (27) of fig iO and 11 P15, the reinforced panels of great length assume these functions - Depending on the case the seals are not necessary.

STORAGE
The construction in two heights makes the nesting panels to save space.

The condition of the seals and the hardware are to be checked every year
