Abstract
ABSTRACT
The sealing of floor joints which are located between two structural bodies (11, 12) comprises a covering profiled element (2) having a cross-section which is preferably an equilateral trapezium and, depending on the requirements of degree of sealing, the sealing means (2.4, 2.5) and a sealing membrane which is laid below the structural bodies 11, 12 plane-parallel to the floor, and items of clamping apparatus (3) which project into the building joint (11, 12, 13) and can be spread between the joint walls by means of the clamping screw (6) in such a way that they are pressed against the joint walls of the building joint (11, 12) and, because of friction of the clamping apparatus (3), are anchored in frictional closure to the joint walls of the building joint (11, 12). Although the length of the covering elements is made uniform in manufacture, as a result of the oblique-faced type ending thereof water-tight abutment points and thus any length of sealing of the building joints are possible.

Description
213~199 SEALING OF FLOOR JOINTS
The invention relates to the sealing of floor joints, in accordance with the precharacterizing clause of Claim 1.
Floors are produced in such a way that provision is made for the longitudinal alterations in the structural bodies by so-called floor joints. As a result of this technique, excessive tensions do not arise in the structure of the floors and the superstructure which otherwise, as a result of overstressing the building material, manifest themselves in mechanical destruction thereof. In order words, the planned division of the floors into elements a few metres in thickness by floor joints which are approximately 9 to 28 mm wide enables uncontrolled cracks and gaps in the structural object to be avoided. The floor joints, which are planned in advance, are sealed as required to prevent the penetration of the influences of weather by filling the building joint with plastic-elastic materials. As a result of their function, the filler materials of the building joint are frequently exposed to weathering. In the course of time, these influences of the weather bring about decomposition, degrading and disintegration of the joint sealing means. This damage arises, in addition to degrading of the elastomers and polymers as a result of ageing, because of progressive frost damage, which occurs wherever the penetration of water and the subsequent occurrence of freezing temperatures cannot be avoided. In accordance with the prior art, joints are produced in such a way that the content of the joint is covered by a synthetic foam plate. Finally, the outer periphery of the joint filling is filled with bitumen or a polymer cement.
This cement has the task, as a sealing means, of preventing water from penetrating. In order to reduce the quantity of cement (e.g. made of silicone) and processing thereof, rubber profiled elements, in particular sponge rubber cords, are frequently additionally laid in the outer periphery of the floor joint. Experience has shown that weathering of the outer cement layer takes some years, so that penetration of water into the floor joint is not prevented despite all these measures of the prior art.
To achieve the object, there is proposed, for example in the publication DE-A-l 658 994, an expansion joint profiled element. This expansion joint profiled element comprises angular rails (1) which cover the joint walls of the floor joint and a flat cover rail (3) with rubber strip adhering to the underside and with items of clamping apparatus (7) which are distributed along the flat cover rail, are connected thereto, can be countersunk into the building joint and can be spread between the angled rails tl), with square attachment pieces (5), countersunk screws (4) and securing means (6), as well as various securing anchoring means (2) and nails for fixing the securing anchoring means (2). The fundamental disadvantages of this construction are as follows; absurdly, it does not permit settling or expansion movements of the structural body, it is provided only for "precise joint guidance", and not least it comprises a plurality of constructional elements and is thus extremely expensive, from manufacturing the parts to storage, handling and assembly.
The present invention has the object of eliminating the said disadvantages.
In accordance with the invention, this object is achieved by the characterizing features of Claim 1.
The sealing of floor joints comprises a covering profiled element formed by a protective covering profiled element which can be lengthened to any extent by attachment pieces and is of corrosion-resistant metal, and clamping apparatus 213~199 distributed along the covering profiled element and connected thereto and projecting into the floor joint and clampable between the joint walls.
So that the covering profiled element is flush with the plane of the floor and does not project outwards, the covering profiled element is let into the floor. As a result of this arrangement, the resistance to rolling of the floor joints and the edge pressure (normal tension at the edge of a loaded body) of the joint edges is reduced in the context of DIN 1054 by improving the load distribution. The preferred shape of the cross-section of the covering profiled element is an equilateral trapezium, the longer of the parallel sides of the covering profiled element lying at the plane of the floor. The edges of the floor recess are therefore obtuse-angled and are thus protected against overstressing beyond the normal force of the load.
If the recess of the covering profiled element is produced by mechanical machining, the floor joint serves to centre the milling procedure. The countersunk bores of the clamping screw are distributed along the axis of symmetry of the covering profiled element and serve to receive the spreadable clamping apparatus which can be clamped between the joint walls of the building joint. The clamping apparatus is centered by the clamping screw and is guided through the floor joint in such a way that the latter is connected displaceably to the covering profiled element before tightening. So that coverings which are sealed with respect to precipitation and which are of any desired length can be produced from the covering profiled elements of pre-fabricated length, the ends of the covering profiled elements are constructed in a manner having oblique faces.
These oblique-faced abutments permit a certain shortening or lengthening of the covering profiled elements as a result of temperature changes, inasmuch as they can move 213~199 over one another in the manner of fishscales. At the same time, as a result of the precision of the raftering, the distance between the profiled elements is kept small, so that the penetration of precipitation is eliminated in this way. Since the edges of the covering profiled elements are broken, a bearing surface is produced at the edge of the covering profiled element. This bearing surface is pressed against the edge regions of the recess by the tightening of the clamping screws. The material of the sealing is determined in accordance with the requirements for sealing, and is laid in the recess. As an example of the sealing material, EPDM and butyl cement in strip form can be mentioned. For hermetically sealing the floor, it is proposed that an additional sealing means be laid. This has the shape of a plane and is laid plane-parallel below the floor bodies, which are separated from one another by the floor joint, as a sealing membrane. It will be understood that abrasion- and corrosion-resistant materials are preferred for the covering profiled elements.
Corresponding aluminium alloys, which are inexpensive to process using extrusion, are suitable. Since bare metal surfaces may possibly be undesirable for aesthetic reasons, after they have been produced the covering profiled elements can be subjected to anodic oxidation to make them matt or coloured or provided with two-component epoxy resins which are suitable for after-treatment.
The advantages achieved by the invention can be seen in the excellent load distribution and the ageing resistance of the covering profiled element and thus in the improvement in load-bearing capacity of the floor joints, in the stages and quality of sealing and in the rationalization effects.
When the recess is produced, the covering can be laid using the simplest of means, such as a pen knife and a screwdriver, by cutting a recess out of the synthetic foam filling of the floor joint. If it is necessary to seal the floor joint, the sealing means is laid in after producing 213~199 the recess. If lacquer sealing of the building joint is required, then the sealing membrane has already to be incorporated before the structural bodies are cast. Use of the invention is suitable for new buildings and, with the exception of the lacquer sealing, for refurbishment work as well. The invention is an effective and inexpensive preventative measure for damage to buildings and thus a means of economical building.
The invention will be explained in more detail below with reference to a drawing illustrating an embodiment. In the drawing:
Fig. 1 shows a cross-section through the floor joint, with the covering profiled element installed, and Fig. 2 shows a cross-section through the open floor joint, with the floor body and the sealing membrane.
The joint sealing means shown in Fig. 1 uses the covering profiled element 2 to span the gap formed by the floor bodies 11 and 12. A gap of this type is called floor joint and is filled with synthetic foam 13 apart from the clamping apparatus 3, which comprises the spreading body 4 and the wedge 5, placed therein, and the clamping screw 6.
Fig. 1 shows the frictional closure system of anchoring.
When the clamping screw 6 is tightened, the wedge 5 is drawn against the covering profiled element 2 and the clamp 4 is thus spread in such a way that it is pressed against the joint walls and thus the structural elements 11 and 12.
At the same time, the covering profiled element 2 is pushed against the outer surfaces of the wall elements 11, 12.
During this,~the clamping screw 6 creates in the bridge-like covèring profiled element 2 a flexural stress which results in pressing the bearing surfaces of the edges 2 2 and 2.3 against the structural elements 11 and 12 and the sealing means 2.4, 2.5 and thus sealing thereof. Fig. 2 213~199 ~ ,~
shows the two structural bodies 11, 12 with the floor joint open and the synthetic foam 13 located therein and the sealing membranes 7, which are overlapped in the region of the floor joint. The sealing membranes are planar, lie ~:
plane-parallel with respect to the structural bodies 11, 12 on the base of the structure and surround the structural bodies for the purpose of hermetic sealing. -:.
