Description

Preparation for sealing the door opening before water enters

The invention relates to a device for sealing a door opening against water ingress, e.g. in the event of storms or floods.

According to the international classification of patents, the invention of this kind belongs to the field of construction, namely to doors, namely door security means, in the present case before water intrusion.

The invention is based on the problem of designing a universal device which, if necessary, can be installed in a door opening with at least about a flat horizontal bottom surface and at least approximately flat outer vertical surfaces, and with which a door opening up to a predetermined height can be sealed at least temporarily and this is to protect it from the ingress of water from the outside, in principle still allowing at least an emergency passage through the door, and the preparation of the door opening itself being unrelated to the need to install additional elements.

· • ·

The device for sealing the door opening is described in FR 2 853 685. It is a rectangular sealing plate which is on the inner i.e. with respect to the door facing sideways along one longer side and the two shorter sides fitted with seals. The gasket along the longer side is intended to fit on the outer surface of the door opening threshold, and each of the seals along the shorter sides is to fit on the outer surfaces of the two vertical walls of the door opening. Furthermore, two pairs of latches are provided at said outer surface or in the facade area at different distances from the ground. Each latch is designed to work with one lath, each of which can be inserted into the pair at least approximately the same distance from the floor as the latch. Thanks to the slats, the gasket plate is then pressed against the door sill and the outer walls against the door surface, which is intended to protect it against water ingress. Before using this type of device, it is necessary to install the aforementioned locks in the building, in addition, the threshold must be very precisely machined in the plane of the door opening itself or. facades. In addition, the sealing is relatively unreliable, since the latch of the plate can only be pressed to a certain extent in the direction of the building, the outer surface of which, among other things, is at least slightly uneven.

For further preparation as described in FR 2 823 525, a door frame or window opening is provided with a frame and, in the latter, a sash, which is surrounded by an inflatable gasket around the perimeter. When there is a risk of water ingress, said gasket is drawn in by air, which is then maintained under adequate pressure inside the gasket. This type of preparation is completely specially designed for each window or door leaf and frame separately. In addition, in the event of a flood in the gaskets, pressure must be generated and maintained, which is most practically possible with the aid of an air compressor. However, in the event of a flood, electricity supply is often disrupted and the provision and maintenance of pressure in seals can be a serious problem.

Further preparation is described in WO 2006/061520. In this case, it is a sealing frame, fitted with seals and as such insertable into the door opening, while being supported in the said opening by means of a support column, and at the same time supported by supporting elements. The frame is U-shaped, consisting of a horizontal arm and two rectangular arms at the latter and at least approximately parallel vertical arms. Between the said arms is inserted a sealing plate which mainly closes the door opening. Along with the said frame and plate, there is a vertically mounted and telescopically mounted and one coaxially connected coaxial parts, which are inserted between threaded and threaded joints, which can be inserted between the sill or. the lower horizontal surface of the neck opening and during the lath i.e. the upper horizontal surface of the door opening. Supporting elements are connected to said column on each side, each of which is connected to the respective area of the sealing frame on the other side. Each of the aforementioned supporting elements consists of a pair of coaxially arranged rods with an internal thread, one of which comprises right and the remaining left thread. The rods are interconnected via a connecting element comprising coaxially projecting ends, one of which comprises a left thread and the other a right thread. The device is installed in the door opening in such a way that it inserts a frame with seals which then rest on the threshold and vertical walls of the door opening. Approximately in the central area of the neck opening, they place the pillar and, by twisting parts of each other relative to the other about the longitudinal axis, consolidate it in the area between the threshold and the lintel. Subsequently, support elements are attached to the pillar, which in turn connect them to the frame. By rotating the connecting elements, the support element in question is supported on the pillar and presses the frame in the direction of the door opening, with the gasket resting on the surface of the door opening, thereby closing the door opening in principle. The more the supporting elements are installed, the more even the alignment of the frame with the seals on the surfaces of the door opening is. It will be understood by one of skill in the art that such preparation is reasonably practicable for predetermined measurements of the door opening and would therefore be difficult to support the claim that it is universal. In addition, it is evident that it consists of a number of fundamentally unrelated and only on-site components, and is therefore relatively complex for the average user to install, especially when faced with a time-consuming emergency. In addition, it is apparent that, on the one hand, the supporting elements resting on the frame and on the other on the frame retain the frame with the plate in place, maintaining this pressure in a plane perpendicular to the direction of hydrostatic pressure in the event of water retention in the event of floods. . In order to even be able to provide the expected functionality in such unfavorable loading conditions, the supporting elements must be very tight, which in principle can even lead to damage in the door opening area. The same applies to the pillar to which the support elements are attached and which is tensioned between the sill and the lintel. The rigidity of the latter depends on the method of construction and the use of the preparation even in masonry buildings with brick walls can lead to damage and / or displacement of the lintel. However, due to the presence of said pillar and supporting elements in the area of the door opening, the passage of the door opening is virtually impossible. This means that even at relatively low water levels, e.g. below 30 cm above the lower edge of the door opening in the threshold area, when walking around the building is still possible, the door opening is practically completely closed and it is impossible to enter or exit the building through it. Considering all the practical circumstances, it is therefore necessary to evacuate the building even if the door is sealed, since holding it without the possibility of exiting the door can often often entail high risks in the event of various problems, and especially if the situation is due to lifting. the water level worsens.
