DE19962200A1 - Universal fastening system with variable spacer sleeves and adaptors contains basic assortment of at least 30 pieces which by at least 4 adaptors offers at least 120 application possibilities - Google Patents

Abstract

The universal fastening system contains a basic assortment of at least 30 pieces which by at least 4 adaptors offers at least 120 application possibilities. It is suitable for each load demand in question from a bell push to a roof canopy. A height bridging is made possible according to load and thickness of insulation material.

Description

The problem

The problem is well known and consists of thermal insulation facades (WDF) Attach accessories.

When attaching accessories, do not apply pressure to the substrate (WDF). Furthermore, no thermal bridges may arise. One solution would be cutting and relining under fasteners, which leads to greater damage to the thermal insulation facade. Overcoming the insulation thickness at very low stress intensity (eg, signs, bell buttons ( Figure 7), lamps ( Figure 8), motion detectors, alarms, house numbers, mailboxes ( Figure 6) is another problem.

The solution

This attachment system demonstrates the possibility of all these problems to eliminate.

This fastening system contains a basic assortment of at least 30 pieces, which offers at least 4 adapters at least 120 applications. It comes for every load stress in question, from the bell button to the Canopy. It is a height bridging depending on load and insulation thickness possible.  

description

The invention is based on the fact that it is possible on thermal insulation facades in Interior on Styrofoam walls or glued Gibskartonwänden one secure fastening.

It can be from 5mm-16mm (or larger) screws, stud bolts or similar come into use.

Depending on the substrate, a distance bridging of 10 mm-160 mm or larger is conceivable. It spacers are screwed together (Figure), which have on its underside (lower part) and at its top (upper part) feet that increase the area to be loaded. This prevents the sleeve slides into the masonry and increases the surface to be loaded on the top. The feet have a thin plastic coating ( Figure 6) which prevents heat transfer between the element to be fastened and masonry. The spacers have a fine or trapezoidal thread ( Fig. 1), which is attached over its entire length. The use of trapezoidal thread is recommended for heavy loads.

Furthermore, in the tops locking ( Fig. 2) are present, which secure this against slipping and twisting when using adapters. These adapters can have a wide variety of shapes and sizes. The hole for mounting the adapter on the spacers know a depression ( Fig. 3). This serves to sink the screw head to ensure a flat surface.

Spacers and adapters should be provided with a surface treatment, to limit the risk of corrosion (galvanizing).

When using a variety of spacers and adapters universal use is possible. For larger diameters, the attachment of stiffeners ( Fig. 8) is necessary. Spacer sleeves for diameters 5-8 are available in full plastic!

For larger versions, a construction test certificate must be requested!

For larger contact diameters (about 100 mm) and a distance of 200-500 mm, use in shuttering as a spacer for formwork panels with a variable foundation width can be achieved ( Fig. 9).

This spacer sleeves of greater length are used which is a large Have internal thread, in which two locking lids (each from the right and left). This is done by means of a crank External square for quick installation.

The inner sleeves remain in the foundation, the locking cover can be reused. When used in formwork all should Parts made of plastic.  

Advantages of use

• - no pressure on external thermal insulation systems
• - No cold spots through plastic coated feet and silicone grouting
• - secure attachment in the masonry
• - Universally applicable for all types of fastening (screws, studs, etc.)
• - Applications in the professional and DIY sector
• - applicable to everyone
• - Also used for interiors as a spacer for poured walls Styrofoam formwork (eg installation of cabinets, etc.)
• - Also used as spacers in formwork construction
• - Increased screwing (rear ventilation) without problems at company signs, billboards

Height compensation at different thread lengths (for example)

Thread length in mm Compensation height in mm 10 10-15 15 15-25 25 25-45 45 45-80 60 80-140 100 100-160

Recommended diameters, lengths, support diameters (variable) in mm

Use table depending on the load and the thickness of the insulation to be bridged in mm (information example)
