UA95157U - PRO NUT MOUNTING METHOD - Google Patents

Abstract

The method of fastening the glass "PRO NUT", in which the polished surfaces of the parts are applied material for connection, clamp the parts and connect at the melting point of the material for connection. Ethylene vinyl acetate (EVA) or PVB film is used as the connection material in a vacuum installation in which the adhesive elements are housed. A PRO NUT fastening element having the appearance of a cylinder with one extended end is inserted into the inner glass plate. , which is inside the triplex, the thread is threaded inside the cylinder to secure the bolt to the required surface, the air is pumped from the installation, the glass plates between which the film is heated to a maximum of 125- limeryzatsiya film in the rarefied environment (-0,92-0,95 bar); then the triplex is cooled to 50-. the pressure in the chamber is aligned to atmospheric and as soon as the temperature of the multilayer glass decreases to 42-, the formation of a triplex glass with a hidden element of fastening "PRO NUT" is completed.

Description

The useful model belongs to construction, finishing works, namely to fixing glass parts, making glass sandwiches with "RKO MIT" fixing, which are used for glazing the facades of high-rise buildings, making internal office partitions, interior elements, suspended ceilings.

There is a known method of connecting glass parts, in which the material for connection is applied to the polished surfaces of the parts, the parts are pressed and connected at the melting temperature of the material for connection, and float glass is used as the material of the parts for connection, and a layer of aluminum or its alloy with a thickness of 0.1-50 μm is used as a material for the connection, and the connection is carried out at a temperature of 200-350 "C (patent of Ukraine Mo 81182, publ. 10.12.2007, bulletin Mo 20) .

The disadvantage of this solution is the complexity of the connection, labor-intensiveness, the use of high temperatures, the difficulty of fixing ready-made slabs on partitions, facades of buildings, etc.

The problem that the useful model aims to solve is to create a simple method of fastening glass parts with the possibility of easily fixing them on surfaces.

The method is based on the following process - a film for connection is taken and placed between the glass plates for their subsequent gluing, the fastening element "RO

MIT" is installed in a pre-made landing slot in the glass and the process of triplex vacuum lamination begins. The sequence of work operations is as follows - glass cutting, giving a bent shape in the polishing furnace, turning the edges, thorough cleaning and degreasing of the surfaces, making a seat in the glass for the "RKO MIT" fastening element. When forming a "sandwich", an ethylene vinyl acetate (EMA) or PMV film and an "RKO MIT" fastening element are placed between the glass plates.

Then all this is placed in a vacuum machine, having previously put it in a plastic bag.

The soldering of glass sheets and the "RKO MIT" fastening element takes place precisely in this installation: the air is pumped out, the "sandwich" is heated to a maximum of 125-130 "C, the film is polymerized in a rarefied environment (-0.92-95 bar); the triplex is cooled to 50-55 "S. When the temperature drops to 50-55 "C, the pressure in the chamber is equalized to atmospheric, and as soon as the temperature of the multilayer glass drops to 42-45 "C, the formation of triplex glass with a hidden fastening element "RKO MIT" is completed.

The process of making a "sandwich" is shown in fig. 1, general view and fig. 2 side view of the product already after the end of the process, where under number 1 is the outer glass plate, which can be with any coating of different colors, number 2 - the adhesive film, C is the inner glass plate, into which the fastening element "RKO MYT" is inserted into the pre-prepared hole » 4, which has the form of a cylinder with one extended end, which is inside the "sandwich", a thread is cut inside the cylinder for fixing with a bolt on the required surface

A simple manufacturing technology makes products cheaper, a hidden fastening element "RKO

"MIT" significantly simplifies the installation of glass plates, allows to improve the quality of the product due to invisible external fastening.
