HOLLOW WALL.

Application mea May e, 1925,. serial No. 28,458.

To all tri/0m 'it may concern:

Y Be it known that I, HANS Furry., a citizen of the Republic of Austria, residing at Modling, near Vienna, Austria, have invented certain new and useful Improve ments in Hollow Walls, of which the following is a specification.

This invention relates to improvements 1n hollow walls composed of a framework which is covered with plates.

The present invention consists in the connection between the plates of each wall forming the hollow wall, at the back side the plates being provided with ribs or grooves and further 'the connection between the oppositely disposed walls of the hollow wall is Carried out by tensioning members arranged in airs and into the grooves of which the ribs of the plates are adapted to engage and which are tightened up with one another in known manner.

The individual plates essentially are formed by a skeleton or netted member, which is produced of ledges or strips overlapping one another and which at least on one side is covered with a suitable materia-l such as wood` artificial stone, asbestos slates, mortar, gypsum, plaster and the like.

'Owing to the formation of the plates by a netting or skeleton and the interengagement of its ledges at the transecting places, the entire cross-sectional area of the said ledges appear as cross-grained wood at the edges oit the plates. On placing the plates side by side always cross-grained woods are abutting, so that any alteration of the wall in consequence of shrinkage or contraction is rendered impossible.

A further advantage of the netted member consists in that gaps are formed in the lateral edges of the plates between the bars of the netted member, suitably shaped pins being disposed in the said gaps. which extend beyondthe edge of the plate and when placing the same side by side engage into the gapso the adjacent plate, thus producing a homogeneous unit, as the plates interengage and are connected with respect to one another and may be glued together during the erection.

One mode of carrving out the present invention is shown by way of example on the accompanving drawing.

At certain convenient distances, posts 2 are mounted in the longitudinal recess of a grooved base l and are furnished with wedge-shaped slots 3. The individual construction-members of the walls are formed of plate-like members rand at their inner sides are provided with wedge-shaped eX- tensions 5, which serve as a means for securing wedge-shaped members 6, the latter being connected with one another by a tensioning or connecting` member 7 in case of connecting with one another the said plates, or if the plates are secured to the post 2 the said members 6 are secured to a member 8, engaging the wedgeshaped slot 3 of the said post. The tensioning members 7 orthe members 8 secured in the 1dost are furnished with slots through which cotters 9 are driven, the latter pressing the wedge-shaped members 6 against the extensions 5 and thus form a stable connection between the plates or for securing thesame to the posts. Preferably the plates are disposed above each other in steeped manner like bricks. In order to bind or connect the individual layers, the edges of the plates are provided with inwardlyV projecting, undercut guidegrooves into which ledges l() are driven. The latter extend from the middle of the plates of one layer to the middle of the plates of the second layer, so that in the present case always two layers of plates, which are not immediately adjacent to each other, are connected or bound with one an-' other. Thus the ledges .l0 form a reliable means for closing-up the space between. the contacting edges of the plates.

. Of. course, if desired, the extensions of the platesy may be formed by furnishing the plate with a conveniently shaped groove, the outer walls of which result in a rib, which does not Vextend beyond the plane of the plate; l

. The plate is provided with a skeleton or netting, formed of bars 4 of the same thick* ness, which overlap each other at the crossing places, so that the entire cross-sectional area appears lat the edges. The netting 4 is covered at both sides with wooden linings or boards l1 or the like, which impart a great rigidity to the netting. If desired plates pressed of a suitable material may be substituted for the boards 11, the said plates being provided, at the inside, with elevated parts corresponding to the holes of the netting and filling-up the said holes if the plates are connected with the netting. The

outsides of the linings may be covered with a facing 12 of artificial stone or the like. At the borders of the plates the netting appears as a comb-shaped member, as the ends of the bars 4 project beyond the outermost bars for half the width of a hole. rlhus it is rendered possible to dispose block 13 into the holes,- formed between two bars, the said blocks projecting beyond the end of the plate and engaging the holes of the adjacent plates, and in this mannear produce a good connection between the plates.

The hollow spaces of the netting, not. only mean a saving of material, but also are a very good means of isolation.

Any movement of the wood is rendered impossible, as the grains of the wood are disposed horizontally and vertically land thus a shrinkage of the wood in any direc- -tion is quite impossible. The distance between the bars of the netting corresponds to certain measurements of the plate, so that at any desired division of the plate always cross-grained wood rests on cross-grained wood.

I claim:

l. A hollow wall comprising in combination, plates forming the walls of the said hollow wall and provided with rib-shaped projections at the back-side, connecting members arranged in pairs for connecting the plates of each wall of the said hollow wall and for connecting the oppositely disposed walls of the hollow wall, and grooves in the said connecting members adapted to be engaged by the said projections.

2. A hollow wall comprising in combination, plates formingthe walls of the said hollow wall and provided with grooves at the back-side, connecting members arranged in pairs for connectingthe plates of each wall of the said hollow wall and for connecting the oppositely disposed walls of the hollow walls, and rib-shaped projections on ythe said connecting members adapted to engage the said grooves provided in the plates.

3. A plate for constructing hollow walls composed of transecting bars which overlap one another at the crossing places and the ends of which extend beyond the crossing places to form a skeleton, and a wooden lining covering the sides of the said skeleton.

Q4. A hollow wall comprising in combination, plates forming the walls of the said hollow wall and provided with rib-shaped projections at the back-side, each plate being composed of transecting bars which overlap one another at the crossing places and the ends of which extend beyond the crossing places to form a skeleton, a wooden lining covering the sides of the said -skeleton connecting members arranged in pairs for connecting the plates of each wall of the said hollow wall and for connecting the oppositely disposed Walls of the hollow wall, and grooves in the said connecting members adapted to be engaged by the said projections.k

A hollow wall comprising in combination, plates forming the walls of the said hollow wall and provided with grooves at the back-side, each plate being composed of transecting bars which overlap one another at the crossing places and the ends of which extend beyond the crossing places to form a skeleton, a wooden lining covering the sides of the said skeleton connecting members arranged in pairs for connecting the plates of each wall of the said hollow wall and for connecting the oppositely disposed walls of the hollow walls, and rib-shaped projections on the said connecting members adapted to engage the said grooves provided in the plates.

G. A plate for constructing hollow walls composed of transecting bars which overlap one another at the crossing places and the ends of which extend beyond the crossing places to form a skeleton, a wooden lining covering the sides of the said skeleton and a facing covering the outside of the said lining.
