Description

The invention relates to the field of construction, in particular to a method for mounting a metal sheet roof insulated with heat-insulating panels on a rafter system. The invention can be used both in the construction of buildings with pitched roofs, and in the repair of such buildings.

The known method of “Fixing systems and method for sealing a facade or roof” (Patent No.EP 2495378 (A2) of 03/04/2011, E04D 3/36, E04D 5/14, published 05.09.2012, also published as DE 102011001114 (A1)). In this method, the roof is fastened with a sleeve in the form of a shaft mounted on the base, with a protruding extended part, which is designed to fasten the elements of the insulation structure, having an inner diameter larger than the diameter of the head of the fastener, but tapering to the lower end and fixed on the base using a nail shaft. The free space is filled with sealants. The sleeve consists of an elastic and mechanically firmly deformable material.

The disadvantages of the proposed method are the complexity and the great complexity of the work due to the need for preliminary fastening of the roof in the installation position. The sleeve is not a fastening structure, after its installation it is necessary to fasten the structure with a screw or a nail rod “blindly”, which impairs the reliability of fastening and does not prevent possible pulling out during operation. The disproportionate amount of the cap of the sleeve may impair the reliability of the seam connection.

A known method of insulation using a binder component - a plastic holder with a hollow shaft hole inside, having internal peripheral ribs (No. EP 0783063 (A1) from 01/01/1996 and No. EP 0783063 (B1) from 01/09/2002, E04D 3 / 36, E04F 13/08, B25B 11/00, E04B 1/00, published on July 9, 1997 “Method for placing fastening elements and fastening elements used therewith”) . After installation, the holder is fixed with a screw using a screwdriver.

The main disadvantages of this method are the complexity of the initial fixing of the insulation, since the holder is not a fastening structure, after its installation it is necessary to fix it using a “blind” screw, and it is difficult to create a folded roof connection over the large head of the holder, the method requires professionalism in operation, errors occur only during the operation of the roof, leading to the separation of the roofing from wind and snow loads.

There is a known method for connecting a seam roof with a heater “Device and method for fastening insulating material)) (Patent No. EP 2366843 (A1) 09/21/2011, application for invention No. EP 20110158271 of 03.15.2011, E04D 3/36, E04D 5/14, E04F 13/08, published: 09/21/2011, No. EP 2366843 (A1), priority document number NL 20102004410 C dated 03.16.2010). The invention relates to the fastening of insulating, in particular, insulation boards and roofing materials. A method of attaching insulating materials, including installing a structure in the form of an elongated shell with a radially expanded second end, which allows it to counteract compressive forces acting on a layer of insulating material, for example, snow on the roof, and securing it to a screw that is screwed through the shell into the rafters approximately 2 centimeters for holding roofing and insulation material.

The disadvantages of this method are the need to secure the roof before screwing the screw and installing the screw on the rafters “blind”, in addition, the greatly expanded end of the dowel can interfere with a reliable folded connection.

The closest technical solution is (patent No. WO 9529342 (A1) dated November 2, 1995, application for invention No. WO 1995JP00748 04/17/1995, E04D 5/14; F16B 13/08; F16B 19/10) “Article fixing method and fixing device ”(Article method of fixing and fixing device). The method includes installing an outer cylinder having a smaller diameter part at the free end of the cylindrical body, after installing the structure, securing it with an inserted shaft with an expanded head on top and an external thread on the free end of the shaft body, twisting the lower free end of the shaft to prevent the slip ring member from sliding.

The disadvantages of this method is that the outer cylinder does not fix the roof covering material, the fastening shaft has a metal head, which contributes to the formation of cold bridges and the possible oxidation of the underlying material, with a small cap size that reduces the percentage of roof fastening reliability.

The objectives of this technical solution are to reduce the duration of assembly of the structure, reduce the cost of work, increase the reliability of fastening, reduce the likelihood of damage to the roof system from wind and snow loads, increase the life of the roof.

The tasks are achieved due to the fact that in the proposed method, the connection of the folded roof with rafters and insulation is realized by means of a plastic dowel and a fastening element having a plastic coating of the head in the form of a plate, according to the invention, pre-drilled installation holes in the rafters from steel U-shaped profiles or wood, drill or punch holes in polyurethane foam panels with "spikes" of longitudinal and lateral connection with adjacent panels glued on both sides with a windproof membrane made of TEND KM-0 non-combustible fabric and perforated holes for increasing vapor permeability, having on the upper side a profile that imitates the crate, a supporting surface on the lower side and stiffening ribs that allow creating an “air” zone, as well as drill or punch holes along the male edge, at the base of the outer side of the ridge, in metal sheets previously prepared for a folded joint, after pre-installation, insert holes into the pre-drilled holes in the rafters plastic dowel-type spacers are fixed, polyurethane panels are fixed on the spacers, gluing the joints of the panels, metal sheets are installed, when using steel U-shaped rafters, a bolt is inserted into the spacer-clamp and tighten it with a clamping nut on the inside of the roof, and when using wooden rafters, a screw with a plastic head is inserted into the clamp-spacer and screwed, while the clamp-spacer adjusts the compressive force, the steel sheets are fastened together I am on a double standing self-locking fold with a sealant.

The invention is illustrated by drawings, where:

- in FIG. 1 shows a roofing cake consisting of a metal roof and a polyurethane foam panel having an external coating of a hydro-windproof membrane with a TEND KM-0 non-combustible fabric;

- in FIG. 2 shows an element of the mounting system;

- in FIG. 3 shows a roof connection with wooden rafters;

- in FIG. 4 shows a molded panel.

The construction of the connection of the folded roof with rafters and insulation consists of a rafter 1, a fixing-spacer of a dowel type 2, molded polyurethane foam panels 3, channels for the output of the generated moisture 9, metal sheets 4, a bolt with a plastic coating on the head 5, a clamping nut 6, and a non-combustible fabric TEND KM-0 "7, seal 8 of the connection of metal sheets.

The method of connecting the folded roof with rafters and insulation is implemented as follows.

The holes in the rafters 1 for the subsequent installation of the roof, as well as the holes in the panels 3 and on the metal sheets 4, are drilled in advance on the working tables or in the factory. After installing the rafters 1 in the initial position, plastic clamps-spacers of the dowel type 2 are inserted into the holes (the form does not necessarily coincide with the drawing). They are equipped with molded polyurethane foam panels 3 having "tenon grooves" for longitudinal and lateral connection, and channels for the release of moisture 9, covered with a non-combustible fabric "TEND KM-0" 7, and metal sheets 4 are fixed on top, the edges of which are prepared for seam connection. In the case of using steel U-shaped rafters, a bolt with a plastic coating of the head 5 is inserted inside the latch-spacer 2, which is wrapped with a nut 6 from the inside of the roof, and in the case of using wooden rafters, a screw with a plastic head is inserted and screwed. Between themselves, the panels of steel sheets are mounted on a double standing self-locking fold with seal 8 according to known technology.

The technical result when applying this method is to reduce the duration of the installation of the roofing, reduce the complexity, facilitate the repair work, the possibility of recycling materials, improve the insulating and waterproofing qualities of the fence in conditions of variable temperature, humidity and mechanical stress, and also, if necessary, use polyurethane panels as a temporary roof. There are no fire hazardous technologies during the execution of the work. The present invention is industrially applicable, as it can be manufactured using known materials and based on known technologies.
