Device for providing protection for structures in water. - Anordning för ästadkommande av skydd för strukturer under vatten.

The invention relates to a device for providing protection for structures in water, such as piles and pier foundations, which device comprises a plurality of mold-forming mold elements extending along and surrounding the surface to be protected, each element being arranged to be joined along its side edges by joining a tubular mold , which element may be sprung apart and arranged around the structure so as to act in the plane of the respective water surface, said joint comprising, in the space inside the element for receiving the casting mixture, flange-forming connecting members extending along the associated side edges of the element to hold the edges together and spaced from the inner surface of the element, the joint thus formed being located inside the mold and covered with concrete, the mold elements having a substantially smooth s outer perimeter shape.

The main object of the present invention is primarily to provide a device of the above-mentioned nature which can be connected simply and efficiently, and to enable the intended joint to be covered and protected in the mold once it has been manufactured.

Said object is achieved by a device according to the present invention, which is substantially characterized by the features set forth in the characterizing part of claim 1.

The invention will now be described, by way of a number of preferred embodiments, with reference to the accompanying drawings, in which: 2 89529

The invention can be applied to a wide variety of structures intended to be placed in water, and preferably immersed in said water, and to be protected from the effects of ice, waves or vessels and other floating objects which threaten to damage said structure. Examples of such structures are piles supporting piers, pier foundations, lighthouse structures and fairway signs, etc.

In Figures 1-7, the invention is illustrated applied to a pile below the pier, where it is desired to correct the so-called "ice cover" 3, which has been damaged by ice, among other things, and which in Figure 1 is seen to be damaged even inside the reinforcement cage 4 attached to the pile 1, which is to be surrounded and enclosed in ordinary concrete 5. After the ice cover 3 is preferably cleaned, in this case is made on the ice cover, and no new ice cover is built, in which case said cleaning is possible with a high-pressure water jet and a scraping machine, a device 6 is placed in the structure 1, which e.g. acts as a mold. A device 6 comprising a plurality of tubular mold elements 7 forming an openable mold, preferably made of stainless steel, preferably stainless steel plate or other stainless metal, is positioned so that its mold elements 7 extend along the surface of its structure which is desired. The example illustrated in Figures 1-7 relates to a device 6 formed by a single mold element 7, which element is preformed so as to expand to form a cylinder, but which can also be opened from its opposing element edges 8, 9 when the element 7 is pushed into the structure 1. on page 10 in the direction of the arrow. However, the device 6 can also be formed of more than one element, which will be understood from the example described below.

The present device 6 is intended to be placed on the structure 1 so that it is mainly in the region of the respective water surface 11. To meet this requirement, the device 6 can be positioned so that it can be supported at least before the final casting by, for example, a lower platform or other lower part which can be attached to the structure 1, said 4 39529 platform also being intended to serve as a base for casting. ropes or straps, are also arranged so that they can be used to support the intended casting mold and the casting mixture contained therein during casting.

The finished device 6, which is intended to act as a casting mold, is positioned so that it can be fastened along the edges 8, 9 of said element 7 by an edge joint 12, which represents a new feature of the present invention.

The joint 12 comprises a connecting member 13, which may be formed by one or more profile rails, which may have a C-shaped cross-sectional profile and which may be of the same material as the mold elements 7, but the element 7 may also have connecting flanges forming internal flanges inside the elements. 14, 15, which are arranged so that they can be tightly connected in pairs to hold the connector member 13 to hold the edges 8, 9 of the element together so as to provide an efficient and reliable connection. Said 13 is arranged to be inserted into the connector body for connecting said fitting members 14, 15 on top, preferably in the direction of arrow 16 across the top of the casting mold area 17. Each connecting member 14, 15 are arranged to extend along adjacent edges of the mold elements 8, 9 a certain distance from the mold element, the internal effective area of 18, wherein said effective surface towards the interior 19 which is to receive the concrete 20 or other suitable casting mixture when the mold is made. Said connecting members 14, 15 may suitably be formed from the bent portion 8A, 9A of the edges 8, 9, in connection with which the connecting members 14, 15 formed by the above-mentioned bent edges 8A, 9A may be adapted to extend substantially forming a shape with the outer edges 8, 9 of the elements. looking outwardly from the interior 19 of the mold toward the outside 22. To facilitate attachment of the connector member 13, it may have guide portions 23A, 23B at its other end 13Ά and an internal, hollow receiving space 23, for example a space 23 extending towards said end 13A . Alternatively, the connecting members 14, 15 may have similar guide members 14A, 15A at their other end 14B, 15B, causing the members to taper, for example.

In order to interconnect said casting element 6, belts can be arranged so as to temporarily act against the outside 24 of the effective surfaces of the element until the connecting member 13 has been pushed over the connecting members 14, 15 and closed them.

Filling of the assembled mold is best done by pumping concrete into the mold and filling the mold upwards from the bottom of the mold, while at the same time the joint 12 inside the mold in question is surrounded by concrete material 20 into which the joint is embedded. A substantially smooth circumferential shape on the outside is provided by an ice guard 6 made in this way, to the outside of which a stainless mold element 7 is still attached.

Figures 8 to 10 show the invention applied to a structure 25 in the form of a pier base with an elongate cross-section, as can be clearly seen in Figure 9, comprising an "ice cover" to be repaired and replaced with a new ice cover 26 as indicated above. A plurality of mold elements 27, 27, 27, etc., the circumferences of which may be straight and / or curved, are arranged to extend along the surface to be protected at a certain distance from the previous ice cover and / or structure 25. A plurality of joints such as the joint 12 described above. 28, 281, etc., are also intended to be arranged on the edges of said mold elements, in connection with which the mold elements 27, 271, etc. are arranged so as to have similar connecting members in the region of said side edges. The molding of the mold elements takes place substantially in the same way as described above, so that internal joints are formed which are arranged to be embedded in the mold-filling concrete material 29. To provide effective adhesion between the mold and the casting mixture 29 6 39529, the mold elements 27, 271 casting gripping points 30, which may be] [-shaped plates spaced a certain distance from the connecting devices. Said ice cover 26 is joined together to form a tube before it is fitted to the intended structure 25, after which it is bent open, like the previous element 7, from an open joint when pushed around said structure 25 before this subsequent joining according to the above example by means of connecting devices extending along the joint.

Finally, Figures 8-10 show the bottom 31 of the finished casting mold 32, which can e.g. comprises angle irons 33 attached to the structure 25 by extension bolts 34 or the like.

The invention is not limited to the illustrative embodiments described above and illustrated in the drawing, but may be modified within the scope of the claims without departing from the inventive idea. For example, the mold element can be realized on a non-flat surface, for example in the case of structures with a conical side surface or in one in which the surface deviates in some way from the vertical.
