Description

Fastening device

The present invention regards an anchor stnp for use in fastening of and ensuring a fixed distance between beams, uprights and similar.

When building new houses and redecorating/rebuilding houses and apartments today, the folding rule is used for measuring set distances between floor beams or similar, between the upnghts of the framework of a house, or between the roof trusses. This is a time consuming and cumbersome process where the position for the beam, upright or roof truss must me measured and marked manually before these are put into position and secured, generally by use of suitable mountings such as Y-steel for roof trusses or tier shoes for tiers of beams. Measuring, positioning and fastening of roof trusses is particularly time consuming, as it is sometimes necessary to attach an provisional block after measuring and marking and then fasten the roof truss before removing the provisional block again.

From GB 2 103 264 there is known a spacer element for beams. The spacer elements described therein consist of an elongated basic plate described with a straight, U-shaped or L-shaped cross section, to which basic plate is fastened a plurality of mounting brackets for attachment of beams thereto, which bracket are spaced in the longitudinal direction of the plate. The elements described therein are useful aids in the construction of a building. However, they are long, straight elements that are unwieldy to transport to the building site.

The object of the present invention is thus to provide a device with which beams, uprights, roof trusses and similar may be fastened to the base while ensuring the desired distance between the beams, roof trusses, uprights or similar, and which are easy to handle during transport and while on the building site.

According to the present invention, this is achieved by a device for fastening of beams, uprights and similar to a base and ensuring the distance between a plurality of beams, uprights or similar, which comprises a long and narrow strip-shaped body in running lengths, in which strip-shaped body is formed a plurality of tongues spaced a specified distance apart, which tongues may be bent up about a bending line, relative to the plane of the long body

Preferably, the bending line is roughly at nght angles to the longitudinal direction of the long body

Moreover, it is preferably that the tongues be positioned along the longitudinal direction of the long body in such a manner that the tongues are paired in twos with their bending lines facing each other, and where an intermediate piece is located between the tongues 10 m each pair, which piece is adapted to the dimensions of the matenals with which the

Preferably, the long body is a perforated metal stnp

ID The invention will be explained in greater detail below with reference to the accompanying figures, in which

Figure 1 shows a top view of an embodiment of the present anchor stnp in the rolled- out state, and

Figure 2 shows a perspective view of the same embodiment as in Fig 1 , with the tongues taken out of the pnncipal plane of the stnp

Preferably, the present anchor stnp 1 is composed of a metal, most preferably perforated 23 metal The anchor stnp 1 is preferably produced and delivered in coiled running lengths so as to let the user cut the stnp 1 to the required length Thus the length of the stnp is not fixed, and may be adjusted at the building site by cutting a desired length of the coiled stnp The thickness of the stnp 1 may vary with the strength requirements Normally, the stnp will have a thickness of between 1 and 3 mm, preferably between o 1 5 and 2 mm

The width of the stnp may be fitted to the requirements. 1 e the dimensions of the matenals with which it is to be used The stnp 1 may be delivered in different widths and thicknesses, deoenαing on the matenals w ith which it is to be used and other requirements

Preferaoh . the stnp is manutactureα in metal and compnses a plurality ot tongues 2 along us length, w hich tongues 2 are cut out in the metal ana. pnor to being used, lie m the plane of the strip 1 Preferably, the stnp is perforateα DV a plurality of holes through hich me stnp or the tongues may be naned to the base, oeams etc However noles are not necessary m order to be able to hammer nails througn. as nails may be hammered through the stnp The stnp may in addition have cut-outs m order to save weight

The tongues 2 can be bent out from the plane of the stnp 1 about a bending line 3 in the form oi a w eakened line m me metal at nght angles to the longitudinal direction ot the stnp 1 The weakened line ot the bending line 3 may be a plurality of holes drilled in a straight line, a stamped bending line or similar The tongues 2 on the stnp are paired so as to make the bending lines 3 face each other with an intermediate piece in between The length of the intermediate piece 4 matches the thickness of the matenals w ith which the stnp is to be used

The t o tongues 2 of a pair point away from each other m the longitudinal direction of the stnp l and may be bent away from tne plane of the stnp 1 by a tool such as a hammer Bending a tongue 2 away from the plane of the stnp 1 leaves a window 6 in the stnp

After placing a groundsill on a foundation w all or other foundation, on which sill a tier of beams is to be placed, the stnp is placeα on and along the length of the groundsill ana cut to the corcect length The positioning of a first beam is measured m the normal manner and the stnp is adiusted in the longitudinal direction to make a space 4 in the stnp correspond to the positioning of the beam

T he ancnor strip 1 is then fastened to the groundsill, for instance bv nails through the stnp 1 and into the groundsill Then the tongues 2 can be bent up and away from the plane of the stnp 1 Preferabh a cut-out 5 is provided in the stnp and/or the tongue for eacn of me tongues 2. so as to allow it to oe gnpped b\ a tool such as a nammer in order to bend the tongue 2 up The tongues 2 are bent up so as to leave them roughh perpendicular to the plane of the strip 1 The tongues of each pair will then be spaced apart by a distance corresponding to the intermediate piece 4. which also conesponds to the thickness of the beams. The beam is then set down m a space between tongues 2, and the tongues 2 are fastened to the beam by use of nails or similar. Using such an anchor stnp on all of the parallel girders for the beams ensures the exact same distance between the beams with a minimum of measurements. In addition, the anchor stnp also acts as a means of attaching the beams to the base.

In the embodiment shown, the anchor stnp has two tongues for each beam. It is however also possible to envisage the stnp with only one tongue per beam This will ensure an exact spacing of the beams but will not provide the same degree of attachment to the base. The most prefened embodiment with two tongues per beam also provides support for the beam and prevents it from overturning.

In the above, the application of the present anchor stnp 1 is descnbed with reference to a tier of beams, and more specifically to the lowermost tier of beams over the foundations of a building. The anchor stnp 1 may however also be applied to the erection of upnghts for erecting a wall or similar on a base The anchor stnp 1 is placed on the base underneath the intended site of the wall and in the direction in which the wall or similar is to run. and fastened m a manner such that a first intermediate piece 4 is positioned at the spot where a first upnght is to be set down

Then the stnp is fastened to the wall or similar along its entire length, the tongues are tilted up as descnbed above, and the upnghts are fastened to the tongues as indicated above In the same manner, an anchor stnp may also be fastened to the upnghts at the top, whereupon the strip is then fastened to a beam or similar above the upnghts

When erecting a lightweight wall, one anchor stnp may be fastened to the floor and one to the ceiling, whereupon the uprights for the lightweight w all is inserted between the conespondmg tongues and fastened to these. Lastly, the anchor stnp may be used for erecting roof trusses. One stnp is placed on either side of the future loft of the house, in the longitudinal direction of the house near the outer wall. The stnps 1 are positioned so that a first intermediate piece 4 in each stnp 1 is positioned correctly m relation to a roof truss that will run at right angles to the stnps 1 and between these. After the stnps have been fastened and the tongues 2 have been bent up as descnbed above, the roof trusses may be fastened to the anchor stnps on either side of the house Here, the anchor stnps will ensure that the distance between the roof trusses is both conect and fixed, and will also support these so as to eliminate the need for provisional blocks to retain them temporanly

The present anchor stnp w ill under normal conditions provide sufficient fastening to the base, provided that the anchor stnp is fastened well enough to the base and the tongues 2 are fastened to the beam, upnght or roof truss it is intended to anchor, by means of nails or tacks Mountings normally used for fastening tiers of beams, such as tier mountings or Y-steel for fastening of roof trusses.

If the beams etc. that are fastened with the present anchor stnp are judged to require additional fastening to the base, these may naturally be secured by means of extra nails or similar extending down into the base
