Description

Technical field

The utility model relates to the field of construction, namely, devices for fastening cladding elements at the transition between two surfaces (for example, floor and wall) and can be used for hidden fastening of skirting boards, decorative profiles, claddings and other similar elements having a fixing groove.

State of the art

A device for fastening cladding elements is known (see US patent US 7594368, September 29, 2009 - the closest analogue), made in the form of an angular profile of sheet metal or plastic. The profile has a wall and a base placed at right angles. A fixing hole is made in the wall, and the base has a supporting part and two tabs formed by bending the part of the base at a certain angle in the direction of the wall. In this case, the end parts of these reeds are bent in the opposite direction.

The disadvantage of this analogue is that the solution does not determine the optimal geometric parameters of the reeds. Moreover, in the product manufactured according to this closest analogue, the product has a small thickness and width of the tongues, and a large radius of rounding, which do not provide sufficient spring properties for reliable pressing of the facing element to the wall.

Utility Model Disclosure

The objective of the claimed utility model is to eliminate the disadvantages of the analogue.

The technical result of the utility model is to increase the reliability of the retention of the facing element.

The specified technical result is achieved due to the fact that the fastening device of the facing element is made in the form of an angular profile of sheet steel having a wall and a base, and a mounting hole is made in the wall, and the base has a supporting part and two tabs extending from the supporting part along the edges of the base and formed by bending the base relative to the supporting part along a curved line in the direction of the wall, while the end parts of these reeds are bent in the opposite direction, and the ratio of the radius of the bending of the base in t he area coupling support portion and tabs for fastening the device profile thickness is between 4 and 6, and the width of each tongue is from 0.25 to 0.35 the width of the base;

In addition, according to private options for implementing the utility model:

- the angle between the plane of the reeds and the plane of the supporting part of the base is 45-65 °;

- the ratio of the bending radius of the base at the interface between the tongue and its end part to the thickness of the profile of the mounting device is from 3 to 4;

- flanging is made in the area of the mounting hole of the wall;

- the tongues are formed by two cuts extending from the edge of the base in the direction of the wall perpendicular to it;

- the mounting device is made of spring steel.

In contrast to the closest analogue, in the considered fastening device, the radius of rounding of the base at the place of the reeds is reduced, and the thickness and width of the reeds are also increased. The authors of the utility model found that for a steel profile, the best retention of the facing element is ensured with a ratio of the fillet radius to the thickness of the profile from 4 to 6 and with a tongue width of 0.25-0.35 of the base width.

The described special cases of the implementation of the design are also aimed at improving the reliability of the retention of the cladding element, however, they are not the only possible embodiments of the utility model. It should be noted that the technical result of the utility model will be achieved without the use of these additional features.

Utility Model Implementation

The claimed mounting device (Fig. 1,2) is made in the form of an angular profile of sheet steel, in particular spring steel. The thickness (S) of the specified profile may vary depending on the size of the product and is usually 0.4-0.8 mm.

The specified profile includes placed at an angle (preferably at a right angle) wall (1) and the base (2). The wall (1) is intended for fastening the claimed device to a vertical surface (3), in particular to a wall, when installing a facing element (4) (see Fig. 5). To this end, a corresponding mounting hole (5) is provided in the wall (1) for accommodating a fastening element (6), for example, a self-tapping screw. To increase the rigidity and reliability of fastening the device around the hole (5), a flange (7) can be made in the form of a bulge directed inward to the part (see Fig. 1, 3)

The base (2) of the fastener is intended for contacting with a horizontal surface (8), in particular with the floor, as well as for holding the facing element (4) by placing the base (2) in the fastening groove (9) (see Fig. 5).

The base (2) consists of a support part (10) in contact with a horizontal surface (8), and two reeds (11), which are formed by the bend of the base (2) relative to the support part (10). In this case, the tabs are placed along the edges of the base.

The ratio of the radius (R1) of the specified bend at the junction of the base from the support part (10) to the tongues (11) to the thickness (S) of the profile satisfies the following condition: R1 / S = 4-6.

It was experimentally established that this ratio provides the optimum stiffness level for sheet steel, necessary for installation on the tongues of the facing element and its guaranteed pressing against a vertical surface due to the elastic properties of the material. With a ratio of less than 4, the tabs will have too high rigidity, which will complicate the installation and retention of the element. With a ratio of more than 6, the tongues will not have sufficient spring properties for installing the device in the groove and fixing it.

The optimum radius of rounding (bending) of the base (R1) is, as a rule, 2-4 mm.

The angle (a) between the plane of the reeds and the plane of the supporting part of the base (angle of bending of the reeds) is preferably 45-65 °. This is due to the presence of the mounting element (4) of the mounting groove (9) in which the tabs are placed. At angles less than 45 ° it is necessary to significantly increase the width of the specified groove (9), which is not always possible, or to reduce the length of the reeds (11), which will lead to a decrease in spring properties when installing the element. At angles greater than 65 °, the tongues will not exert sufficient pressure on the facing element (4) for its reliable retention.

The end parts (Pa) of the tongues (11) have an additional bend in the opposite direction (opposite to the wall (1)), which is necessary for the sliding of the facing element (4) when it is vertically mounted on the tongues (11).

The ratio of the radius (R2) of the rounding (bending) of the base (2) at the interface of the tongue (11) with its end part (11a) to the thickness (S) of the device profile should preferably satisfy the condition: R2 / S = 3-4.

This ratio is most optimal from the point of view of ease of installation of the facing element (4).

To ensure the required operability of the device, it is advisable that the width (a) of the tongue (11) is from 0.25 to 0.35 of the width (B) of the entire base (2). With values less than 0.25, the tongues will not have the required rigidity, and with a ratio of more than 0.35, spring properties will not be sufficiently provided.

These tabs (11) of the base (2) can be technologically formed by two cuts ({^ made in the base and extending from the edge of the base in the direction of the wall perpendicular to it (see Fig. 4). In this case, the remaining central protrusion of the base can form an additional supporting tongue (10a) of the supporting part (10), which increases the stability of the mounting device.

The device can be obtained by means of metal processing techniques known to the person skilled in the art. In particular, cutting down of reeds in a steel tape, subsequent cutting of the tape into blanks and bending of blanks can be applied.

The fastening device can be used to install various cladding elements (4) at the interface between two surfaces, for example, a vertical surface (3) of a wall and a horizontal surface (8) of a floor (see Fig. 5). To do this, the mounting device is installed on the floor in the place of its interface with the wall. The wall (2) is attached to the horizontal surface (3) of the wall through the hole (5) by means of a fastener (6). Next, the facing element (4) with a vertical groove (9) is installed vertically by placing the tabs (11) in the specified groove (9). In this case, elastic deformation of the tongue (11) in the direction from the wall (2) occurs, which creates a clamping force of the element in the opposite direction and ensures reliable retention of the cladding element (4).

Despite the fact that the operation of the device is demonstrated by the example of fastening a facing element at the junction of perpendicular floor and ceiling surfaces, it can also be used to install facing elements on other types of surfaces, the angle between which can be different from 90 °.
