Description

An arrangement for securing a post In a foundation
The present invention relates to an arrangement for securing a post in a foundation, especially for road signs, said foundation being provided with a vertical hole to receive the root of the post, and fastening means for locking the post to the foundation.
Posts, and especially road signs which are placed close to or in a traffic artery, are liable to be knocked down by a car so that the post is bent or broken and has to be replaced.
The fastening means for locking the post to its foundation at present comprises a ring which is secured to the top of the foundation by the aid of bolts and which clamps an 0-ring of rubber down towards the top of the foundation, so that the latter expands radially and is firmly clamped to the root of the post. Bolts are screwed into threaded bushings which are cast into the top of the foundation which consists of concrete. If hit, the concrete around the lining will often break up and the bushing will work loose. It will then be impossible to secure a new post for a road sign in the existing foundation. The resposible services then have to dig up the old foundation and cast a new one. Especially road signs and the like which are placed close to a pavement corner or on a traffic island, are exposed to destruction by traffic, e. g. a truck turning too abruptly so that the truck body or a possible trailer hits the post and bends or breaks it. Known technology, thus, involves considerable expenses in connection with replacement of road signs and the like.
It is, thus, an object of the present invention to propose an arrangement rendering it easier to secure a post to a foundation or to provide a new post on a foundation which was destroyed in a manner as mentioned above. It is another object of the invention to propose a fastening means for a post on a foundation which is less subjected to destruction. Posts, e.g. for road signs may, consequently, be erected in a simplified and less expensive manner. The same is true of replacement of damaged posts, e.g. for road signs. By the aid of a further development of the invention destruction of road signs will occur in much fewer instances than previous¬ ly, which will, obviously, reduce costs of replacements and repair.
According to the invention this is achieved by an arrangement of the kind as mentioned above, which is characterized by a journal which is adapted to the hole in said foundation, by the fact that a rubber means is provided at one end of said journal, which rubber means has the same or substantially the same cross sectional dimension as the journal, that a screw passes through said rubber means, which screw is secured to the end of said journal and is intended for cooperation with a plate or the like with a threaded hole for axial compress¬ ion of the rubber means so that the latter expands radially towards the wall of the hole in said foundation, and that said plate is provided with fastening means for securing the post.
A further development of the invention is characterized by the fact that fastening means for firmly securing the post comprise a locking plate or locking disk with the same or approximately the same cross sectional dimension as the first mentioned plate, with a central threaded hole intended for engagement with the screw, and that the post or an element intended to be connected with the post is permanently fastened to said locking plate.
An embodiment of the invention is characterized by the fact that the post or the element which is intended for connection with the post is secured to the locking plate by the aid of a resilient intermediate member. In a further development of this embodiment said intermediate member consists of a rubber means which is secured to the locking plate on one side, and the post or an element which is intended for connection with the post is embeded in the rubber means from the opposite side.
The invention is disclosed in more detail below with reference to the drawing, in which
Figure 1 shows an arrangement for securing a post to a foundation of a conventional kind,
Figure 2 shows a first embodiment of an arrangement according to the invention, and
Figure 3 shows another embodiment of an arrangement according to the invention.
The conventional fastening means, as shown in Figure 1, comprises a concrete foundation 1, which is embedded or cast in the ground 2. Centrally in foundation 1 a hole 3 is provided to be vertical in a mounted position and to receive root 4 of post 5. At the upper end of foundation 1 two or more sleeves 6 and 7 are embedded in the cast with a threaded hole 8 opening upwards. A ring 9 with a downwards concave annular groove 10 is slipped onto root 4 of the post for cooperation with a rubber ring 11. By the aid of head bolts
12, which are screwed into sleeves 6 and 7, plate 9 is urged y down towards the top of foundation 1, causing rubber ring 11 to be compressed in an axial direction. Rubber ring 11 will, thus, expand radially and is firmly clamped about root 4 of the post to lock post 5 firmly to foundation 1. If hit by a car or the like a piece 13 of concrete may be broken off. Consequently, one or more of the threaded sleeves 6 or 7 may work loose from the foundation. A new post 5 then cannot be inserted and secured to the foundation, but the latter has to be removed to be replaced by another foundation.
The embodiment shown in Figure 2 constitutes a first embodiment of an arrangement according to the invention, which is used to secure a new post, e.g. for a road sign. Piece 13 is indicated to be broken off, and so is sleeve 6 of Figure 1. The arrangement according to the invention for securing post 5 comprises a journal 14 which is inserted into hole 3 in foundation 1. As shown in the drawing, the journal may consist of a pipe onto the upper end of which a plate 15 is welded. Centrally in plate 15 a screw 16 is secured to project upwards. A plate 17 with a threaded hole is provided on the screw. By screwing plate 17 onto screw 16 a rubber sleeve 18 is compressed in an axial direction between plate 17 and plate 15 on journal 14 and said sleeve is, thus, expanded radially to be firmly clamped towards the wall of hole 3. The device is thus safely secured in the foundation. A locking plate 19 having the same cross sectional dimension as plate 17 and having a central threaded hole is secured by welding at lower end of post 5. Locking plate 19 is screwed onto the freely projecting portion 16' of screw 16 and is firmly tightened. Thus, a new post 5 is secured in the old, damaged foundation at very low cost. The arrangement may also be used for erecting a post the first time, e.g. for a road sign. In this manner a less expensive foundation is achieved, since it is not necessary to embed threaded sleeves 6, 7 by casting.
In Figure 3 a further development of the arr yangement according to Figure 2 is shown. In this embodiment too a journal 4 is provided, with a screw 16, a rubber sleeve 18, a plate 17, and a locking plate 19. In this case, however, the locking plate is not secured directly to post 5. A journal 20 is secured to locking plate, via a rubber means 21, which is vulcanized onto locking plate 19 at one side. From the other end of rubber means 21 journal 20 is embedded and ancored in the rubber means by the aid of a plate 22 which is provided transversally. Journal 20 has a dimension fitting into the pipe-shaped post 5 and is locked to said post by the aid of one or a plurality of set screws 23.
