Abstract

A flood protection device to prevent floodwater 4 entering an air vent opening 1 in a building comprises an enclosure having an open back sealingly attached to a wall and covers the ventilation opening in the wall to thereby form a duct with the wall and the device. The device has an opening 2 in communication with the duct and the wall opening. The device opening is at a higher position than the wall opening. The seal 3 may be mastic and bonds the device to the wall. The device may be mechanically fixed to the wall with fasteners. The opening in the device may comprise louvers, an overhang or shaped to prevent rainwater or other falling water from entering the device opening. Water may enter the device opening and hence building when floodwater reaches the required height and thus equalises the pressure of water on either side of the wall to prevent structural damage. The distance from the bottom of the wall opening to the lowest opening in the device should not exceed 900mm as pressure from water greater than this may cause structural damage. This distance may be reduced when the device is fitted to weaker structures.

Description

Flood Protection Device This invention relates to a device to prevent floodwater entering the air-bricks or other low level ventilation openings in the wall of a building or other structure.
Buildings with cavities under their ground level floor(s) normally have one or more openings through the outer walls to provide ventilation of the cavity. These openings are naturally below floor level. Door openings, windows, etc are naturally above floor level. Therefore in the event of flooding occurring at these properties the first way water will enter the building is through these under-floor ventilation openings.
Most of the devices currently available require someone to physically close a flap or valve before each flooding event occurs. This is often not a practical proposition. It is then necessary to remember to re-open it after the flooding danger has passed. Many require a builder to remove the old vent and fit the new anti-flood version in its place. There are a few automatically closing devices available but these are complicated and expensive. This device overcomes all these disadvantages.
Another problem with many of the currently available devices is that they do not have a reliable safety release system, which allows water to enter the building in the event of the height of the flood posing a threat of structural damage to the wall.
According to the present invention there is provided an enclosure, having an open back, which when bonded and sealed to the wall around the ventilation opening in the wall, forms a duct, utilising the wall as one side of the duct, leading upwards from the wall opening to an opening in the enclosure which is at a higher level than the opening in the wall.
A specific embodiment of the invention will now be described by way of example with reference to the accompanying drawings in which: Figure 1 shows in perspective, the device bonded and sealed to the wall with a lower portion of the body cut away for clarity.
Figure 2 shows a cross-section of the device under flood conditions.
Figure 3 shows an enlargement of the top portion of Figure 2 Referring to the drawing the flood protection device comprises an enclosure with an open back, which is placed over the ventilation opening in the wall 1.
Preferable the device is positioned so that the bottom inside edge of it is a short distance below the bottom of the wall opening as shown in Figure 1. A seal 3 makes a watertight join between the edges of the device and the wall. In this embodiment of the device the seal is made with a mastic type of compound, which also bonds the device to the wall. Alternatively the device could be mechanically fixed to the wall with fasteners and the seal only used to stop water from entering between the device and the wall.
--
Near the top end of the device are openings to the atmosphere 2. In this embodiment of the device the openings are formed through a mouldeci surface, which is shaped to give a louvred effect as illustrated in Figure 3. This will prevent rainwater from entering the openings and thereafter being directed through the wall opening.
The horizontal cross sectional area of the cavity inside the duct formed between the device and the wall should ideally be no smaller than the cross sectional area of the openings in the wall vent 1. The combined open area of all the device vents 2 ideally, should also be at least this big. This will ensure that the airflow 5 will not restricted to any great extent -see figure 2.
The depth of floodwater the device will prevent from entering the wall opening is determined by the distance D from the bottom of the wall opening 1 to the bottom of the lowest device vent 2. Maximising this will give greatest protection.
However, this distance should not normally exceed 900 mm as the pressure under water deeper than this can cause structural damage to the wall. When water rises higher than the device vents 2 the water will flow through them and down the duct formed between the device and the wall. This water will then flow through the wall opening and into the building thus equalizing the pressure of water on either side of the wall and preventing structural damage. In the case of a device being fitted to a weak structure the distance D can be reduced thereby restricting the maximum water pressure on the wall in the event of a flood. *0

Claims (2)

  1. Claims 1. A flood protection device having an open back, which when bonded and sealed to the wall around the ventilation opening in the wall, forms a duct, utilising the wall as one side of the duct, leading upwards from the wall opening to an opening in the device which is at a higher level than the opening in the wall.
  2. 2. A flood protection device according to claim 1, in which the opening in the device has Louvres, an overhang or is shaped in such a way as to prevent rainwater or other falling water from entering the device through the opening.
