Description

Device for mounting a stretch ceiling

The utility model relates to the field of construction, in particular to devices for the installation of suspended ceilings.

A device for mounting a stretch ceiling is known [1, Patent RU 2192523, IPC ЕВВ 9/30, priority 04.04.2001, published 10.11.2002], made in the form of an elongated figured profile containing shelves from which a place is formed for fixing the figured profile and a place for fastening a harpoon on it with a web of stretch ceiling bordered in a harpoon, and the place for fastening in the profile of the harpoon is made in the form of a collar on one of the shelves of a shaped profile with the possibility of positioning on this collar with pressing against the end of the harpoon.

However, the disadvantage of this device for the installation of a stretch ceiling is the complexity of its design, as well as some inconvenience of mounting the harpoon due to the need for the mandatory availability of such fastening of three shelves of figured profile. This also limits the design of the device for use in it of various types of profiles.

It is known more simple in its design, more versatile in application and more convenient for harpoon mounting, a device for mounting a stretch ceiling [2, Profile systems /. Electronic pecypc: http://en.barrisol.com/products-attachment-system-s.htm#titre-profilstradition. Access date 06/06/2015].

It is made in the form of an elongated figured profile containing shelves, from which a place for fixing the figured profile and a place for fastening the harpoon on it is formed, with a stretch ceiling trimmed in the harpoon, and the place for fastening in the harpoon profile is made in the form of a bend, internal parts of which a gap is formed with the possibility of location in it and on the free end of the bend - the free end of the harpoon in the case of using the device.

However, the disadvantage of the prototype device is that the bend is made possible only partially tight fit to the free end of the harpoon together with the end of the stretch ceiling canvas when using the device, which is not reliable enough and universally, since it does not allow to perform such a device with different types of profiles , especially with profiles that have curved decorative surfaces. More reliably and universally, a device for installing a stretch ceiling adopted as a prototype of a utility model [3, Patent US 5413300 (A), IPC B44C 7/02, EV04/22, EV04/30, conventional priority 05/13/1992 (FR), published on May 9, 1995].

A device for mounting a stretch ceiling according to the prototype [3] is made in the form of a curved profile elongated along the length, containing shelves, from which a place is formed for its fastening and a place for fastening a non-metallic oval-shaped C-shaped harpoon on it along with the edged end of the stretch ceiling web made in the form of a bend, the shelves of which form a bend gap with the possibility of placing in it and on the free end of the bend the free end of the C-shaped harpoon in case of using the device.

In the shaped profile of such a device, the bend is made with the possibility of a predominantly snug fit to its free end of the C-shaped harpoon together with the end of the stretch ceiling web bordered in it, and also with the possibility of overlapping the bend gap with the free end of the C-shaped harpoon.

In addition, a bevel is made at the free end of the bend from the side of its gap, while the bend gap is larger than the thickness of the bend shelves, and the bevel at the free end of the bend is made on the outside of the bend.

The disadvantage of the device according to the prototype [3] is the lack of reliability of fastening on it a C-shaped grapun and the canvas of the stretch ceiling as a whole.

This is because the C-shaped harpoon is not made of metal material, so it is enlarged in size and made with convex surfaces, forming an oval shape. Such an increase in its volume is due to the lower strength of the non-metallic material of the C-shaped harpoon than metal. However, when using stretch ceiling paintings of a large area, a considerable effort is required to tension them by connecting the bend of a shaped profile with a C-shaped harpoon. Therefore, such a bend will be affected by significant support reactions from the side of the bend, which can cause, especially when the structure (softening) of the non-metallic material changes at high temperatures and during the natural “aging” of such material, the appearance of cracks that can weaken the web tension. Those. there is an unreliability of fastening of the device according to the prototype [3].

In addition, the design of the device according to the prototype [3] involves the use of a large-sized C-shaped harpoon of a spherical shape, which lengthens the free end of the shaped profile of the device and causes the formation of a bending moment of large magnitude from the tension forces of the canvas.

This as a whole reduces the reliability of fixing both the profile (device) and the entire connecting unit for the installation of a stretch ceiling.

Therefore, the objective of the utility model is to increase the reliability of mounting the device for mounting a stretch ceiling.

The problem is solved in that the device for mounting a stretch ceiling, made in the form of an elongated figured profile, containing shelves, from which a place is formed for its fastening and a place for mounting a C-shaped harpoon on it along with the edged end of the stretch ceiling canvas, made in the form of a bend, the shelves of which form a bend gap with the possibility of placing in it and on the free end of the bend the free end of the C-shaped harpoon in case of using the device, while the bend is made with both by baking the possibility of a predominantly snug fit to its free end of the C-shaped harpoon together with the end of the stretch ceiling web bordered in it, as well as providing the possibility of overlapping the bend gap by the free end of the C-shaped harpoon, in addition, a bevel is made on the free end of the bend from the side of its gap has distinctive features: in its size, the curvature gap of the curved profile is less than the thickness of the shelves of this curvature, and the bevel at its free end is made from the side of its gap.

Fulfillment of the size of the curvature of the curved profile is smaller than the thickness of the shelves of this bend is aimed at providing the possibility of using a smaller in size and more reliable in strength and fastening than in the prototype [3], metal C-shaped harpoon, which increases the reliability of fastening the device.

Performing a bevel on the free end of the bend from the side of its gap will allow, unlike the prototype [3], where such a bevel is made on the outer surface of the free end of the bend, will allow for a more convenient connection of the C-shaped harpoon with the said bend in the short space between the vertical profile shelf and the bent end of the bend. This allows you to use a shorter free end of the shaped profile in the device than the prototype [3], thereby reducing the bending moment from the action of the tension forces of the web in the connecting node. What is also aimed at improving the reliability of fastening.

Additional distinguishing features of a utility model for a device:

- the bend of the shaped profile is fastened with its shelf, for example, bayonet connection.
