DESCRIPTION:
BRIEF SUMMARY
The present invention relates to an arrangement for use in joining together two plate-shaped elements, which form an angle, usually 90.degree., with each other.
In the boarding of posts, girders and the like there are employed according to known engineering practice, which has changed little the last 10-20 years, boarding elements which are held together by means of various collars or the like which are fastened with relatively short intermediate spaces around the boarding and thereby hold the individual boarding elements in position. This solution is very demanding on labour and time in that the collars have to be nailed to the boarding elements and have to be removed after use.
By the very fact that the boarding work in many casting operations constitutes a substantial portion of the costs, improvements are constantly being sought after, but as mentioned above without significant changes having been made in engineering in recent years.
The need for improvements is thus apparent, and the object of the present invention is to effect boarding of corners more rapidly and simpler and hence cheaper.
This is achieved by means of an arrangement which is designed as an angled means, one leg of which extends substantially at right angles to the main plane of the one plate-shaped element and projects away from a second plate-shaped element, and the other leg of which extends substantially at right angles to the main plane of the second plate-shaped element and projects away from the first plate-shaped element. The legs of the angled means forming abutments against a surface, which is rigidly connected to the respective plate-shaped element and is detachably fastened to the latter.
The invention will be further explained in the following description having regard to the accompanying drawings, in which:
FIG. 1 shows a horizontal section where the arrangement according to the invention is employed for boarding of a corner in a post by means of boarding cassettes.
FIG. 2 shows a corresponding section to FIG. 1, but where the boarding is constructed by means of boarding members.
FIG. 3 shows a perspective view of the arrangement of FIG. 2.
FIG. 1 shows a horizontal section of an arrangement according to the invention for use in boarding of a corner in for example a post by means of boarding cassettes where the angle a between the boarding cassettes is 90.degree..
Each boarding cassette consists of two plates 10a, 10a' and 10b, 10b' respectively, which are usually made of plywood and which have a certain spacing, for example 10 cm. from each other. Each of these plates can alternately face towards the concrete. Between the surfaces there is arranged along their edges a U-shaped element, legs of which, such as the leg 16a, project outwardly as an extension of the plates i.e. in alignment with the plates. In addition the element is designed with an inwardly projecting flange which the plywood plates form an abutment against and which they are detachably fastened to by means of for example rivets (not shown).
On boarding a corner, two boarding cassettes 10a, 10b are mounted at an angle a to each other as illustrated in FIG. 1. In the illustrated embodiment, the angle is as mentioned 90.degree., something which moreover is the most customary. An angled means 11 having legs 12, 13 which form an angle which is as large as, but opposite relative to the angle a between the cassettes 10a, 10b, is arranged between the outwardly projecting legs of the boarding cassettes. The angled means 11 forms thereby an abutment against the bottom 14a, 14b of the U-shaped element of the boarding cassette and forms with its free end 15a, 15b an abutment against the outwardly projecting leg 16a, 16b of the U-shaped element. At the top part the angled means 11 is as illustrated, angled in the form of steps, so that it forms an abutment against each U-shaped element, which is an extension of the inner plate 10a, 10b. In this way the angled means 11 will be arranged safely in position between the outwardly projecting members 16a, 16b and is fixed to
