Description

The utility model relates to the field of construction, in particular, the construction of wooden structures consisting of supporting and supported parts, for example, facade or terrace flooring, and more particularly to fasteners for facade or terrace boards, located on the back of the fixed board, made in the form of a plank. It can be used for hidden or invisible fastening of wooden boards for the decoration of facades, terraces and other surfaces.

The fasteners are known from the prior art (patent RU 129131 U, published: 06/20/2013), characterized in that it is located on the back of the fixed board with several holes for fastening elements (screw, self-tapping screw) in it for connecting the board to the fasteners, and also with at least one hole for the fastener (screw, self-tapping screw) for connecting the fastener to the guide (lag), the ends of the fasteners protrude beyond the ends of the board, while one end of the fastener holds the board by placing it under the previously fixed board in the gap m I wait for the board and the guide (lag), and the second end of the fastener holds the board through at least one hole with a fastener in the guide (lag), characterized in that the fastener is made in the form of a trough profile with an external flange ("boat"), the presence of a horizontal shelf, lateral longitudinal and transverse shelves, placement of lateral longitudinal and transverse shelves at an angle of 45 to 90 ° with respect to the horizontal shelf, and the transverse flanging exceeds the width of the horizontal bar taking into account the longitudinal flanging, as well as the ability to place a stopper on a horizontal shelf. To form a gap between the boards, instead of a measured gasket, a stopper is used, made in the form of a folding part of the fasteners, the stopper is placed on the upper end of the board, so that the subsequent board adjoins the stopper with the lower end.

An invisible fastener is known (patent RU 181267 U, published: 07/09/2018), characterized in that it has an omega-shaped profile, in the mounting plane of which there are at least two holes for self-tapping screws for the board and at least one disassembled hole for a guide from one end of the fastener and one open flanged hole for a guide for mounting the first board - from the other, in addition, in the mounting plane of the invisible fastener there is a stopper made in the form of a tab bent upward from the mounting plane, width p equal to the required clearance between the boards, located along the longitudinal axis. The amount of removal of the front end of the fastener is determined by the stopper. The stopper width varies from 5 to 8 mm and is selected depending on the type of wood used and the width of the board.

Known fasteners (patent RU 124276 U, published: 01/20/2013), characterized in that it is located on the back of the terrace and / or facade boards with holes for the fastening element and several holes for self-tapping screws for facade and / or terrace boards and also with at least one hole for the guide (lags), the ends of the fasteners protrude beyond the ends of the board, while one end of the fasteners is held by placing it under the previously fixed board on the guide (lag) in the gap between the board and the guide (lag) , and the second end is held through at least one hole by a fastening element in the guide (lag), characterized in that the fastener is made in the form of a thin channel. Fasteners perform with the possibility of placing a stopper, which allows you to form an equal gap between the boards. The width of the stopper is calculated based on the gap required between the boards and is at least 3 mm, and the depth of cutout of the stopper is based on the thickness of the boards to be joined, but not more than half the width of the fastener. The stopper is made in the form of a folding bar, which is formed by a cutout in the plane of the fixture, followed by bending in the opposite direction from the plane of fit of the fixture to the terrace and / or facade board. In particular cases, the stopper can be bent to the outside from the channel shelf, if necessary, from the inside to the channel shelves. In this case, the stopper plane can be turned both parallel to the channel shelves and perpendicular to them, or, in a particular case, the stopper plane is turned at the required angle to the channel shelf. The angle of rotation of the plane of the stopper depends on the required position of the terrace and / or facade boards, for example in the "Christmas tree". The stopper is located on the upper end of the fastener, so that the hole for the guides (lag) is located above the stopper, this ensures the most effective stopper, due to the bilateral fixation of the fastener on the structural elements.

The closest analogue is fasteners (patent RU 155482 U, published: 10.10.2015) for a facade or terrace board, located on the back side of a fixed board, made in the form of a bracket with several holes for self-tapping screws for facade and / or terrace boards and at least one hole for the log, while one end of the fastener is designed to be placed under the board previously fixed on the lag in the gap between the board and the lag, and the second end is designed to be secured through at least one hole with a fastener in the lag, it has a detent strip which is made of unbendable neck strap plane and is located along its axis, characterized in that the strip is formed as a flat rigid plate and the plate has two tabs located on the axis of the plate between the extreme opening in the plate and the end plate.

The technical problem of all known solutions and the prototype is that the stopper is made in the form of a folding cut-out from the plane of the bar. The stopper is located on the upper end of the board, so that the subsequent board adjoins the stopper with the lower end. As a result, the stopper crashes into the end of the board and not only spoils it, but the board also has an offset due to this cut-in of the stopper into its end. Thus, the stopper does not perform its function efficiently enough.

Even if the plane of the stopper is unfolded (as in RU 124276 U) by focusing its plane on the end of the board, since it is folding, it will also not be able to fulfill its function due to the slight bending under the force of the end of the board resting on it.

The objective of the utility model is to eliminate these disadvantages.

The technical result of the utility model is to increase the strength of the stopper function in terms of holding the board by reducing the depth of cut of the stopper into the end of the board and eliminating the bending of the stopper under the action of the pressing force of the end of the board.

The specified technical result is achieved due to the fact that the claimed fasteners for facade or terrace boards, located on the back side of the fixed board, made in the form of a strip with several holes for screws for boards and at least one hole for the log, while one end of the fastener is designed for placement under a board fixed earlier on the lag into the gap between the board and the lag, and the second end is designed to be secured through at least one hole with a fastening element in the lag, the bar having a stopper to tory strap is made of a plane and is located along its axis, characterized in that the stopper formed by bending strap plane between two adjacent slits.

Preferably, the slots in the deflection zone of the stopper are parallel.

Preferably, stiffeners are provided in the deflection zone.

Utility Model Implementation

Fasteners for facade or terrace boards are located on the back side of the fixed board and are made in the form of a strip 1 (see Fig. 1) with several holes 2 for self-tapping screws for boards and at least one hole 3 for the log.

One end of the fastener is designed to be placed under the board previously fixed on the lag in the gap between the board and the lag, and the second end is designed to be secured through at least one hole 3 by a fastening element in the lag.

The strap 1 has a stopper 5, which is made of the plane of the strap and is located along its axis.

New is that the stopper 5 is made by deflection 7 of the plane of the strip 1 between two adjacent slots 6. The deflection 7 is formed by punching in the zone of the slots 6, which are previously performed in the strip 1.

Due to the deflection 7 of the plane of the bar 1, the stopper 5 is formed in the form of an arc, at the end of which the board abuts. Due to the increase in the contact area of the stopper 5 with the end of the board, the latter almost does not crash into the stopper 5. Moreover, the deflection 7 is a very strong stop, since it is connected by two ends beyond the plane of the strap 1, and not one as a stopper in known solutions. No matter how much the board rests against the stopper 5, the stopper will not bend, since the stopper is an arch and the pressure exerts on it from the end, which does not allow the board pressure to somehow change the deflection height of the stopper 5.

For this reason, the stopper 5 of the claimed utility model provides increased strength of the function in terms of holding the board by reducing the depth of cut of the stopper into the end of the board and eliminates the bending of the stopper under the action of the pressing force of the end face of the board.

The slots 6 in the deflection zone 7 of the stopper 5 can be arranged in parallel or can themselves be made in an arc.

To enhance the strength of the stopper 5 in the zone of its deflection 7, stiffeners 8 can be made (see Fig. 2). These stiffening ribs 8 can be performed on the plane of the bar 1 before making slots 6 in it.

The bar may have a different profile, for example, as shown in FIG. 3, the bar 10 has an omega-shaped profile. Also on the plank can be used an open bead hole 9, which is used by analogy with the solution RU 181267 U, when the first board is fixed on the guide (lag) through an open bead hole 9 with a self-tapping screw on one side and through hole 3 with a self-tapping screw on the other.

The bar may also be shortened, as shown in FIG. 4, with the smallest allowable number of holes - that is, the shortened bar 11 has only two holes 2 for facade and / or terrace boards and one hole 3 for the log.

Thus, the claimed utility model in the minimum permissible design, providing the working function of fasteners for facade or terrace boards, must have at least two holes 2 for facade and / or terrace boards and at least one hole 3 for logs, as well as a stopper 5.
