    In particular, an object of this description is to propose an improved bracket for anchoring a barrier to support posts.
    In particular, another object of this description is to propose an improved sound barrier.
    Another purpose of the description is to propose a method for forming a sound barrier.
    These and other objects are achieved by the invention as defined in the appended claims.
    In a first aspect, the invention generally relates to a bracket for anchoring a barrier unit to support posts. In a basic embodiment, a profiled sheet material having a first fastening section for a barrier unit, a second fastening section for a post, separate from the first fastening section, and an elastically deformable section joining the first and second fastening sections are used to elastically absorb thermal movement in the barrier unit.
    In a second aspect, the invention relates to a sound barrier with sound barrier units mounted at intervals at fixed anchored support posts and consisting of planks mounted in a frame for the barrier units. In a basic embodiment, the sound barrier units are mounted at resp. support posts by means of brackets according to this invention, whereby the first fastening sections for barrier units are firmly fastened at a resp. frame for the barrier units and other fastening sections for a post are firmly attached to a resp. support post.
    In another aspect, the invention relates to a method for forming a sound barrier in which sound barrier units are formed by assembling planks in a frame for barrier units and periodically mounting the barrier units at support posts. In a basic version, the sound barrier units are mounted at resp. support posts by firmly attaching a first attachment section for a barrier unit, in a bracket according to this invention, to the frame of the barrier unit and by firmly attaching a second attachment section for a support post to resp. post.
    These basic embodiments offer the main advantages of effectively allowing ternally induced relative movement between planks in the barrier unit and thereby maintaining the general shape of each barrier unit even at temperature variations. They will also allow easy and quick installation of the brackets as well as of an entire barrier.
    Preferred further developments of the basic idea of the invention as well as embodiments thereof are set out in the dependent subclaims.
    Advantages offered by the invention, in addition to those described, will be readily apparent upon reading the following detailed description of embodiments of the invention.

    DETAILED DESCRIPTION The invention will be explained below with reference to exemplary embodiments of a bracket for anchoring a barrier unit to a support post and a barrier using such brackets for mounting barrier units at resp. support posts as well as a method of forming such a barrier. The embodiments relate to an application of the invention to sound or noise barriers which utilize vertically arranged planks or plates of plastic for forming fixed barrier units. It should be emphasized, however, that the invention can be used in other areas where barriers are formed by planks, slabs or panels consisting of other materials with similar coefficients of thermal expansion. For the sake of simplicity, the invention will in the description and claims refer directly to barriers, but it should be emphasized that this term is intended to cover all types of walls, fences or panels for use in different environments where problems with thermal movement can arise. The illustrations are thus only for the purpose of describing preferred embodiments of the invention and are thus not intended to limit the invention to details or to any particular field of use.
    It is to be understood that the specification covers the incorporation of features relating to other applications as well as any combination of features described therein. As mentioned above, previous solutions for overcoming thermal movement problems in barriers were usually based on the use of sliding joints. This invention seeks to provide a more efficient and versatile solution to such problems by taking a new approach to managing thermal motion in barriers and barrier units. One purpose is to provide a fairly simple solution that compensates for thermal movement in a barrier structure. The solution will take into account and adapt for significant dimensional change caused by tennis expansion and contraction of, for example, barrier planks, panels or tiles.
    Basically, this is achieved by means of a barrier bracket which will allow relatively unlimited movement of the barrier in a vertical direction relative to the support posts but will stop movement of the barrier in the two horizontal degrees of freedom of movement. It is essential that the movement in the vertical direction practically does not cause any plastic but only purely elastic deformation.
    The invention will be explained below with reference to exemplary schematic embodiments thereof, which are illustrated in the accompanying drawings 1-15. In Figs. 1-8, a first embodiment of a bracket 1 is sketched which is used to flexibly anchor exemplary barrier units 21 at support posts 30 in a similarly exemplary sound barrier 20 (Figs. 5-8 and 15). In these typical embodiments, the barrier units 21 may have upright or vertically arranged barrier planks 22 of a material, such as plastic material, with a rather high coefficient of thermal expansion. The planks 22 are mounted to a metal frame construction 23 described later. The bracket 1 consists of a sheet-shaped material 2 with expedient elasticity to elastically absorb thermal movement which may occur between the barrier unit 21 and support posts 30 due to thermal expansion or contraction of the often used the barrier planks made of plastic.
    In the embodiment according to Figs. 1-8, the bracket 1 is preferably a profiled flat metal plate or plate 2, e.g. of commercial steel grade. It has a first fastening section 3 for a barrier unit, a second fastening section 4 for a post, separated from the first fastening section by an elastically deformable middle plate section 5. The middle section 5 joining the first and second fastening sections 3, 4 acts to elastically absorb thermal movement in the barrier unit 21. 10 15 20 25 30 6 Along one side of the plate 2, the first fastening section 3 for a barrier unit is shaped like a fold / bend with an appropriate angle ot, here approximately 90 °, from a general plane P1 for the adjacent middle plate section 5. Holes 3A for receiving fasteners 9, such as screws and nuts or rivets, are formed in the fastening section 3 for a barrier unit, the fastening elements 9 acting to secure a frame 23 for a barrier unit 21 (Figs. 5-8 and 15) at the attachment section 3 for a barrier unit. The attachment section 4 for a post is a fold along an opposite side of the plate 2. Holes 4A for receiving fasteners 10, such as a U-bolt or a jumper with nuts, are also found therein. These fastening elements 10 act to secure a support post 30 (Figs. 5-8 and 15) at the fastening section 4 for a post, which extends generally parallel to the fastening section 3 for a barrier unit.
    The profiled plate 2 further has a fold / bending 7 of at least 120 ° in the middle section 5 of the plate, at a position close to the second fastening section 4 for a post. This fold 7 in the middle plate section 5 of the profiled plate 2 can preferably be folded / bent down by 140-170 ° towards itself to give the desired elasticity in the position next to the second fastening section 4 for a post. When forming a bracket 1 in a commercial steel grade, this fold 7 is important to allow sufficiently elastic movement without causing any plastic deformation of the material. The rather “sharp” folding angle is preferable to provide stability and thereby avoid the barrier construction “adding”. With such a downwardly directed fold 7, the adjacent second fastening section 4 for a post will be folded back in an expedient manner in order to extend generally parallel to the fastening section 3 for a barrier unit. The middle plate section 5 is continuous or unbroken and will, in a mounted operative state in a barrier, lie above and cover an upper end of the support post 30.
    Figs. 9 and 10 show a modified second embodiment of the invention which is a variation of the first embodiment. Here, the first and second fastening sections 103, 104 as well as the fold 107 have a generally identical shape and profile with those according to the first embodiment. In this case, however, an opening 106 is provided in the middle section 105 of the plate 102. The opening 106 extends from a position near the fastening section 103 of a barrier unit, through the middle plate section 105, through the largest part of the fold 107 and to a position near the attachment section 104 for a post. This means that when mounting a barrier at a support post 30, the support post will initially extend through the bracket 10 15 20 25 30 7 101. The opening 106 is mainly arranged to obtain a compact configuration which tightly encloses a support post 30 which is received therein in an active state.
    As indicated, the fasteners 1, 101 described can be used for mounting a sound barrier 20 shown in Fig. 15. Such a sound barrier may preferably consist of barrier units 21 formed by firmly attaching planks 22, such as sheet piles or plastic plates, to a frame 23 for barrier units. In a practical example, the planks 22 may each have a length of approximately two meters and the mounted barrier 20 may have a length of up to 50-100 meters or more. In such an application, the barrier may need to be able to withstand considerable horizontal wind strength from behind and from the front, depending on the wind direction. At the same time, a relatively moderate vertical pressure from the expanding / shrinking planks in the barrier should be allowed to elastically deform the bracket vertically.
    The frame 23 for barrier units takes up the weight from the planks 22 and is normally formed by separate spaced horizontal steel bars 23 which preferably have a U-shaped profile and are arranged with their open sides facing each other. The steel rods 23 generally extend transversely relative to vertically aligned planks 22 received in their U-shaped profile. The sound barrier units 21 are then mounted at intervals / intervals at respective support posts 30 which are firmly anchored in a foundation or a foundation, normally in the ground G. In applications using brackets 101 according to the second embodiment, the sound barrier units 21 are mounted more precisely at resp. support posts 30 by extending a support post by resp. bracket 101 before the firm attachment of a bracket 101 first fastening section 103 for a barrier unit at the frame 23 of a barrier unit, in the manner described, and by firmly securing the second fastening section 104 for a support post at resp. post. In the illustrated embodiment, the brackets are attached to an upper rod of the frame 23, while the lower rod of the frame can be attached directly to the respective frame. support posts 30.
    By means of the method according to the invention described above, a sound or noise barrier 20 is formed which comprises sound / noise barrier units 21 consisting of planks 22 of plastic which are mounted in a frame 23 for a barrier unit. Using the described brackets 1, 101, an upper area of the barrier unit 21 is mounted by means of the barrier unit frame 23 with intervals / intermediate tubes at firmly anchored support posts 30 for a barrier, so that thermal contraction and / or expansion of the planks will occur. to be taken up, not primarily by the frame 23 but by the elasticity of the brackets 1. With fastening sections 3, 103 for the barrier units firmly fastened to a frame 23 for the barrier unit and with fastening sections 4, 104 for the support posts firmly fastened at resp. support posts, the barrier units 21 are kept intact and thermal movement is fully absorbed by the fasteners 1, 101.
    A third embodiment of the bracket 201 according to the invention is shown in Figs. 11 and 12. This embodiment is another variation utilizing features from the first embodiment. In this case, a plate or plate 202 is formed at least for the main part of spring material, and preferably capercaillie steel is used. By using fi spring material, the necessary elastic, resilient property to elastically absorb thermal movement will be obtained without the need for any sharp fold as in the first two embodiments of the bracket. The first attachment section 203 for barrier units and the middle section 205 of the plate are similar to those of the first embodiment. The first fastening section 203 is again a 90 ° bend along one side of the plate / plate 202 and with holes 203A for receiving fasteners formed therein. When a barrier 20 is to be mounted, the holes 203A will receive bolt and nut joints 9 to secure the frame 23 to barrier units 21 at the brackets 201. The middle section 205 of the plate / plate is continuous and lacks an opening. Thus, the support post 30 will not extend through the bracket 201 which will be reassembled covering the upper end of the post 30. The second attachment section 204 for a post is a fold / bend along an opposite side of the plate / plate 202. has a flat unbroken surface 204B which is secured to a side surface of a post 30, such as by gluing or welding, and may have a slightly narrower width than the attachment section 203 for a barrier to fit the side of the post.
    Figs. 13 and 14 show a fourth embodiment which is a further variation of a bracket 301 which combines features of the second and third embodiments. Again, as in the third embodiment, the profiled plate / plate 302 consists at least in the middle section 305 of spring material, e.g. spring steel. In this case, as in the first embodiment, an opening 306 is provided for receiving a support post 30. Here, the opening 306 in the operative state is formed between two separate, cooperating parts 302.1, 302.2 of a divided plate / plate 302. Thus, it comprises divided plate / plate 302 separate plate parts 302.1, 302.2 which together form a first fastening section 303 for a barrier. In this case, the plate members 302.1, 302.2 each have a separate first fastening section 303.1, 303.2 for a barrier shaped as an approximately 90 ° bend along one side of the plate portions and with holes 303A for receiving fasteners formed therein. When a barrier 20 is to be mounted, the holes 303A will receive bolt and nut joints 9 to secure the frame 23 to the barrier unit 21 at the brackets 301. In a further modification, the plate 302 may also be formed in one piece by extending the spring steel material between the plate members 302.1, 302.2 at the first fastening sections 303.1, 303.2. The second fastening section 304 for a post consists of an end portion 304.1, 304.2 of a resp. separate middle sections 305.1, 305.2 of the plate parts 302.1, 302.2 and a bracket 312 attached, as by welding, to a support post 30. Finally, the end portions 304.1, 302.2 of the plate parts 302.1, 302.2 are secured to the bracket 312 as by means of bolt and nut joints 9 or nit band.
    The barrier bracket has been shown in embodiments specially designed for barriers with vertical or standing barrier planks, but can with minor modifications be adapted for use with barriers that have horizontal or horizontal planks. In other alternative, but not specifically shown embodiments of the invention, variations of the shown parts of the bracket according to the invention may be used without departing from the scope of the invention. Such variations may involve the use of materials other than those mentioned or other types of dressings than the normal bolt and nut dressings mentioned above. To exemplify this, the embodiments discussed with spring material can use any possible type of spring material other than metal material, such as a composite material or stainless steel. Furthermore, depending on the application and on the materials used, different parts can be secured to each other by welding, riveting or bonding / gluing. It should be emphasized that although the invention has been described and illustrated with specific reference to an application at a sound or noise barrier, the invention is in no way limited to such applications. The basic principles of the invention can be applied in other areas where barriers or fences of similar configuration are used.
    This invention has been described in connection with what are currently considered to be the most practical and preferred embodiments, but it will be appreciated that it is not limited to the embodiments shown and described. It also covers every possible combination of features described and shown herein and is therefore intended to cover various modifications and equivalent arrangements covered by the spirit of the appended claims and the scope of the appended claims.
