Abstract

Spacing element for battens (8) which are used for fixedly mounting an outer roof cladding such as roofing tiles, and which, by means of the spacing element, are held horizontally orientated and at a slight distance above a preferably felt-covered false roof (6, 7). The spacing element which has an annular wall (1) disposed between the roof (6, 7) and the batten (8), is designed so as to replace so-called counterbattens and to eliminate rust and moisture problems. In the edge turned to face the roof (6, 7), the spacing element has diametrically opposed recesses (4) for ventilation of the space within the spacing element, of which one recess is always turned to face downwardly. Between the recesses (4) there are disposed abutment portions (5) which rest on the roof. In the opposite edge, the wall (1) of the spacing element has an arched extension (3) which abuts against the upper surface of the batten (8) and which forms, between itself and the batten, a ventilation channel (10).

Description

SPACING ELEMENT
Technical field:
The present invention reVtes to a spacing element for such batten, as are in supporting and retaining an outer roof cladding, for example roofing til and which, by means of some spacing retainer element are disposed horizontal on a subjacent- and preferably a felt-covered roof.
Background:
In roof laying, use has conventionally been made of a false roof of material which will accept nails, such as, generally, planks, fibre panels or the li This roofing material rests directly on the roof truss and is coated on the upper side with a water and oisturetight material, for example tarred roofi felt. On the tarred roofing felt, use is made of so-called counterbattens w run from the ridge to the eaves parallel with one another and which serve t hold the battens at a certain distance from the felt so as to form, beneath the battens, drainage and ventilation spaces for such water as possibly may penetrate in beneath the outer roof cladding. The battens run at right angle to the counterbattens, that is to say in a horizontal direction, and serve f anchoring and supporting the outer roof cladding.
Technical problems:
The use of counterbattens as spacing elements between the battens and the ro felt involves several disadvantages both as regards the work which "is requir in mounting them in place, and as regards their function and working life.
These counterbattens are mounted in place simply by nailing straight through the tarred roofing felt on the subjacent roof, which may be time-consuming a troublesome to perform, since the counterbattens are long and flimsy. The na in place of the counterbattens also entails that the roofing felt is punctur by nails at anunnecessarily large number of places.
In terms of function, counterbattens are less suitable partly because they a exposed to rot attack and partly because condensation easily occurs in the i face between different materials, i.e. between the nail and the counterbatte and between the counterbatten and the tarred roofing felt. Since this conden - . sation cannot be ventilated off in an efficient manner, it will readily be perceived that the counterbattens run the risk of being exposed to rot attack at the same time as the nails will rust considerably.
One form of spacing element which is intended to replace these counterbattens is previously known in the art. The prior art spacing elements are as a rule manufactured of plastic material and, in one embodiment., . -.e two concentric walls designed as tubular sleeves, whose axial extent determines the height at which the batten will be located above the roofing felt. These two concen walls are then, at one end, closed by means of a washer or collar, which, on use, is turned to face up towards the batten. The spacing elements are used in such a manner that the washer is nailed through, the nail being driven in so hard as to realise pressure abutment between the end edges of the tubular sleeves and the subjacent roofing felt.
The above-described prior art spacing element variations is possessed of sev eral serious disadvantages, of which one resides in the fact that the edges of the sleeves will have a tendency to force their way through the tarred ro ing felt, at least during the nailing operation. Furthermore, these spacing elements cannot be caused effectively to seal against the tarred roofing fel for which reason moisture and possibly running water may easily penetrate in the space around the nail so that there is thereby the risk that moisture acc pany the nail through the opening in the tarred roofing felt and down into t subjacent roof. Naturally, there is also the risk that the nail rust rapidly in the damp environment which it is to be feared will prevail internally in the spacing element.
Object of the invention:
The object of the present invention is to realize a spacing element of the t mentioned by way of introduction, the spacing element being designed in such a manner as to obviate the above-outlined drawbacks.
The solution:
According to the present invention, this object is achieved if the spacing e has a circumferential wall disposed between the roof and the batten, and is characterized in that the element, in its edge turned to face the roof, h at least one recess for ventilation of the space within the wall, and that t spacing element, in its edge facing the batten, has a projection which is di to positionally fix the spacing element in relation to the batten.
In one advantageous embodiment of the present invention, the wall should be in the form of an approximately cylindrical tubular sleeve. This embodiment is suitably characterized in that the wall has two recesses which are forme between abutment portions connected to portions of the end surface of the w turned to race ths "oof, these abutment portions being intended fu. _._._. en against the roof, and that the projection consists of an axial extension of the wall,.the extension taking up a centre angle which is less than approx. 120°.
Further advantages according to the present invention will be attained if t subject matter of the present invention also possesses the features as set in claims 3 and 4.

The invention will now be described in greater detail with particular refer to the accompanying drawings. On the drawings, Fig. Vis a side elevation o the spacing element.

Fig. 5 is a t plan view of a batten and a portion of a subjacent spacing element. Fig. 6 i a section taken approximately along the section line B-B in Fig. 5.
Description of the preferred embodiment:
The spacing element according to the present invention comprises a circumfe preferably cylindrical wall 1 which has an axial extent which determines t height on which a batten will lie above the upper surface of the false roof, as a rule a tarred roofing felt. The cylindrical wall may in practice suitab be of a height of approx. 15mm and has at its upper edge 2 an extension or projection 3 along a portion of its circumference, the projection being, in t circumferential direction, of such a length as to take up a centre angle of approx. 60°.
In its edge turned to face the upper surface of the false roof, the cylindri wall has two recesses 4 which are located in diametrically opposed relations The remaining circumferential portions of the cylindrical wall are united wi feet or abutment portions 5 which, in the illustrated embodiment, are design as segment-shaped panels having a material thickness which approximately coi cides with the material thickness of the cylindrical wall. The . -- . __
5 are of one-piece construction with the cylindrical wall.
When the spacing element according to the invention is to be mounted in place it is placed on a felt covering 6 which is laid on a false roof 7. The abut¬ ment portions 5 will, here, rest flatly with their bottom surfaces on the upp face of the felt covering 6. It follows that a channel will be formed between the abutment portions 5 via the recesses 4 which establish communication betw the space inside the cylindrical wall 1 and the ambient atmosphere.
The upper end edge 2 of the cylindrical wall 1 serves to support the battens 8 which are then used for mounting and retaining the outer roof cladding. Mounting of the battens 8 is realized in a per se conventional manner by mean of nails 9 which are driven right through the space inside the cylindrical wa and through the opening in the lower edge of the spacing element which is for between the both abutment portions 5. Furthermore, the spacing element is pla in such a manner that the projections 3 abut against the upper face of the ba which facilitates mounting both of batten and the spacing elements, so that these are held in place during the mounting work. Moreover, mounting of the spacing elements in the above-described manner will entail that there will be formed, between the upper face of the batten and the inside of the projection 3, a ventilation channel 10 which establishes communication between the space inside the cylindrical wall 1 and the atmosphere.
The use of the abutment portions 5 in the lower end of the spacing elements is of double purpose; namely: first simply to realize the above-discussed rec esses 4 for ventilation of the interior of the spacing elements, and secondly to realize an abutment surface against the felt covering 6 of such dimensions as to eliminate the risk that the felt covering be damaged either on mounting of the battens and spacing elements or at later stages when someone, for exam treads on the battens or the outer roof cladding mounted thereon.
According to the invention, the projection 3 is placed in such a manner that both of the recesses 4 will be located vertically -bove one another when the spacing element is mounted with the projection 3 in abutment against the uppe face of a horizontally directed batten. It will follow from this that such wa as may possibly run onto the felt roofing 6 and may have entered into the inn space within the spacing element may freely run off again which thereby compl ly obviates the risk of moisture damage either in the area of penetration of the nail through the felt roofing or to the nail itself.
o: ~ϊ In those alternatives when the spacing element has only one recess 4, this should naturally be placed diametrically opposing the projection 3, so that the recess will always be located on the underface of the spacing element w this is mounted in the intended manner.
The invention may be modified without departing from the spirit and scope o the appended claims. Thu_. it is possible to design the abutment portions 5 in such a manner that they also extend on the outside of the cylindrical wal Furthermore, the spacing element need, naturally, not be of cylindrical for but may be elliptical , polygonal such as square or rectangular. In the alte native with a polygonal spacing element, for example, a square element, the projection 3 is placed so as to extend on both sides of one of the edge line of the spacing element. This will ensure that the upper region of the spacing element always- offers sloping surfaces which permit fully acceptable water r off. In this alternative, the recess 4 is, naturally (if only one is used), placed straight downwardly in relation to the projection 3.
