Abstract

A method and a device for anchoring a suspension band in a structural element, such as a ceiling, having a bore. The method consists of forming a loop or bight in the band and driving it into the bore by means of the wedge device which is engaged in the bight with the enlarged forward end of the wedge device innermost in the bore. The device consists of two wedge members which are connected in longitudinal alignment which may be separated by a fracturable impression therebetween. When the upper wedge member is fully engaged in the bore, the lower member is separated from it and is inserted into the bore alongside the first member but on the opposite side of the one leg of the band and is driven home to clamp that leg of the band between the two wedge members and also to clamp the other leg of the band between the side of the bore and the other wedge member. The first wedge member is provided with stop ears to position it in the bore so that its leading end does not engage the bottom of the bore. Preferably the two wedge members are stamped out of a common sheet of metal material.

The method consists of forming a loop or bight in the band and driving it into the bore by means of the wedge device which is engaged in the bight with the enlarged forward end of the wedge device innermost in the bore. The device consists of two wedge members which are connected in longitudinal alignment which may be separated by a fracturable impression therebetween.

PAIENIE AUG 1 31974 w I NARA PROCESS AND D VICE FOR ANCHORING A BAND USED TO MOUNT VENTILATION DUCTS ETC. IN A CONSTRUCTION The invention submitted here concerns a process and a corresponding device for anchoring a band used to mount ventilation ducts etc. in a construction, eg a roof in which a hole serves for this purpose, by wedging the band in said hole by means of two wedge units. This invention will primarily be used in the building sector. In house construction it is often necessary to mount or secure ventilation ducts, suspensed ceilings, cable ladders, pipes etc. in steel bands. In such cases the question arises as to the secure anchoring of the steel bands in the roof, walls and floor. This is easily solved by the process and corresponding fastening device according to the manufacture and its extremely low mounting costs; moreover, the process requires no special tools for implementation.
The process according to the invention is characterized by that the front end of one of the two wedge units, positioned one behind the other, is inserted into the hole with the band folded and straddled over said front end and driven in by hammering against the rear end of the second wedge unit, and the second wedge unit is then'broken loose from the aforesaid first wedge unit, which has already been inserted, and finally the second wedge unit is inserted at the side of the first one in the hole and is likewise driven into the hole with a hammer, whereby the wedging causes the mounting band, as well as the two separate wedge units, to be pressed against the walls of the hole ensuring that the mounting band is secure.
The device for implementing the process is characterized by that the wedge elements consist of two wedges constructed in one piece with a fractural impression placed where the two are joined.
Accordingly, it is recommended that the wedges be constructed with the side walls tapering lengthwise toward one another, forming two wedges with their tips pointed toward one another and constructed with an interjacent fractural impression.
In order to prevent the first wedge half from being driven too far in, the operative design is advantageous in that between the aforesaid fractural impression and the wedge in front there are side projections which are made wider than the diameter of the hole.
In order to prevent damage to the band when the first wedge is being driven in, the wedge which is to be driven into the hole first shall be sloped at its front end, in accordance with a submitted operative design.
Both Of the wedges, which come in one piece, are, in accordance with their well-adapted operative design, made of long, thin, died plate, preferably U-shaped.
The invention will now be described in greater detail in Conjunction with the attached drawing which shows an example of the operative design of the anchoring device, in which FIG. 1 shows a sectional view FIG. 2 shows a terminal view and FIG. 3 shows a plane view of the anchoring device,
while FIG. 4 shows the anchoring device together with a steel band during the first stage of anchoring,
FIG. 5 shows the anchoring device and the steel band during the second and final stage of anchoring,
FIG. 6 shows a cross section along lines VIVI in FIG. 4 and FIG. 7 shows a cross section along lines VIIVII in FIG. 5.
In the figures, 1 gives a comprehensive picture of the anchoring device. The anchoring device is of steel and forms what is mainly a continuous U-section with its end segments 13, 14 and 15. In the middle segment of the U-section the side walls are reduced to the level of the bottom of the U-section and form feathers 6 and 7 at the side projections providing a simple way to prevent wedge la from being driven too far into hole 17. On either side of feathers 6 and 7 are seen waists 8 and 9, with waist 8 being provided with a fractural impression and, consequently, is intentionally weaker than waist 9. Waist 8 is designed to be easily broken subsequent to anchoring. The side walls of the U- section have edges 2-3 and 4-5 which incline toward one another and by so doing form sloping sections toward waists 8 and 9. At the extreme end of the wedge-shaped unit la recess 10 can be seen, through which the side walls of the U-section show semicircular ends 13 and 14 and edges 11 and 12.
FIG. 4 shows the first stage of anchoring when the U- section with its end segment has been inserted into bore 17 together with doubled steel band 16, which encloses (straddles) the end segment of the U-section with its bevelled ends 13 and 14. At the conclusion of this process the anchoring device is inserted until the side projections with feathers 6 and 7 hold against the sides at the opening of bore 17.
FIG. 5 shows the second stage of anchoring subsequent to breaking the outer wedge-shaped unit of the U-section at the intentionally weakened waist 8; rotating it half a turn around its longitudinal direction, it is inserted and driven into bore 17 so that its bevelled edges 2 and 3 press the lower right segment tangent to wedge segment 1a of the -U-section and its bevelled edges 4 and 5. The wedge-shaped unit is driven in with several light blows of a hammer against end segment 15 of the U-section. Due to wedging, steel band 16 becomes securely anchored in bore 17. The anchoring receives additional reinforcement if traction is put on steel band 16 by way of the weight of the mounted ventilation ducts or other weight.
