Abstract

The technical solution relates to the field of energy, namely to tape clamps for fastening insulation (thermal insulation and / or waterproofing) mainly on pipelines, as well as on pipeline valves and equipment. In addition, it is possible to use a clamp for fastening, for example, thermal insulation mats when stacking them or rolling them into rolls. The technical problem to be solved by the technical solution is to simplify the manufacture of the clamp and reduce waste during its production by eliminating such operations as cutting the tape to form protrusions (staples), preliminary bending of the staples. The technical result is to increase the reliability of the clamp by eliminating the possibility of irreversible deformations due to stresses arising in the places where the antennae are bent to form protrusions that serve to form staples, which can lead to the detachment of the fastening protrusions (antennae). The technical result is achieved due to the fact that the fastening clamp is made in the form of a flexible tape, on one end side of which there are two pairs of flat fastening protrusions, and each pair of protrusions is made with the possibility of bending to form a bracket, while the flat fastening protrusions are located across the flexible strip and permanently attached to it.

State of the art

Known metal band clamp, which contains a tape, at one end of which there is a lock, made by bending a flat plate and forming a buckle with antennae, which is fixed on the tape using bullets. Fixation is carried out by wrapping the tape twice around the elastic shell, passing the end of the tape through the buckle, which is preliminarily attached to the bulges on the bent section with a 180 ° bend angle of the other end of the tape and after tightening the clamp, the tape is re-bent 180 ° and locked by pressing the buckles with the antennae (RU 2191932 C1 2002.10.27).

Known tape clamp for piping, which includes a fastening tape and a buckle of the holder. During the strapping process, the fastening portion of the strap gradually curves inwardly against the protruding and open insertion sections of the holder buckle. The fastening tape is first caught by the latch protrusion when passing through the holder buckle when it is secured around the pipe, and then is again gripped by the fastening lugs, and thus can be attached to the holder buckle without using the tool US 2009265896 A1, 2009.10.29).

Known fastening clamp, made in the form of a tape, on one end side of which there are flat fastening protrusions and are made in one piece with the tape (US 4751769 A. 06.21.1988).

Known bandage tape with a welded lock, containing a tape with at least two main antennae protruding beyond the lateral lines limiting the tape, and each main antenna has a bend, the line of which is located at an angle of 45 degrees to the main direction of the tape, characterized in that the main antennae are additionally curved towards each other (along lines parallel to the main direction of the tape, and the bends at an angle of 180 degrees are located near the lines limiting the original tape), and the ends of the main antennae are connected by an integral connection. The permanent connection can be made by resistance welding. The tape may contain two additional antennae (the total number of antennae is four), two on each side, with the main antennae formed by the inner sections of the original tape, and additional antennae formed by the outer sections of the original tape (RU 135033 U1, 2013.11.27).

Known clamp with a slip-on lock for a tape clamp, which is made of a plate, including a buckle consisting of a base, side walls and a cover, and tendrils for fixing the tape, placed on the continuation of the base of the frame and directed towards the cover, characterized in that the cover is formed by two shelves directed towards each other, and the antennae are separated from the shelves (RU 67659 U1, 2007.10.27).

Known collar containing tape with at least two tendrils protruding beyond the lateral lines that delimit the tape. Each antenna has a bend, the line of which is located at an angle to the main direction of the tape. The number of antennae can be four, two on each side (RU 114110 U1. 2012.03.10).

The closest analogue to the claimed technical solution is a clamp in the form of a metal tape, intended, among other things, for fixing heat-insulating shells. At the end of the metal tape, three longitudinal cuts are made, which form antennae, made integral with the tape, which are bent to the sides during installation and fix the opposite end of the tape (RU 2472980 C1, 2013.01.20). The disadvantage of the closest analogue is the lack of reliability of the fasteners (antennae) due to their bending relative to the tape.

The technical problem to be solved by the technical solution is to simplify the manufacture of the clamp and reduce waste during its production by eliminating such operations as cutting the tape to form protrusions (staples), preliminary bending of the staples.

The technical result is to increase the reliability of the clamp by eliminating the possibility of irreversible deformations due to stresses arising in the places where the antennae are bent to form protrusions that serve to form staples, which can lead to the detachment of the fastening protrusions (antennae).

The technical result is achieved due to the fact that the fastening clamp is made in the form of a flexible tape, on one end side of which there are two pairs of flat fastening protrusions, and each pair of protrusions is made with the possibility of bending to form a bracket, while the flat fastening protrusions are located across the flexible tape and are permanently attached To her.

It is preferable that the flat fastening protrusions in each pair are made in the form of two identical flat pieces of metal tape, preferably in the form of two rectangular thin-walled plates and preferably have a thickness and width equal to the thickness and width of the flexible tape.

Preferably, the flat attachment protrusions are part of an H-shaped element cut from a thin-walled plate, in which the flat protrusions are connected by a bridge.

It is preferable that the flexible tape is made of metal, preferably of sheet metal. The flexible tape can be made of plastic.

It is preferable that the fastening protrusions and are made of metal. It is preferable that the fastening clamp includes two pairs of fastening protrusions, the first of which is located at the end of the flexible tape, and the second is located behind the first pair at a distance from it, while it is preferable that the distance between the pairs of fastening protrusions is greater than the width of the fastening protrusion.

The thickness of the flexible strip t is 0.25-1.0 mm, the width of the flexible strip is 8-40 mm, preferably 15-20 mm, the thickness of the fastening protrusion being 0.25 to 1.0 mm, preferably 0, 4-0.8 mm.

The flat fastening protrusions have a width that is 3-30 mm, preferably 5-10 mm, while the total length of each fastening element that forms the fastening protrusions is 1.2-3.0 clamp band widths, preferably up to 2, 0 clamp band width. The distance between the flat fixing protrusions is 5-100 mm, preferably 15-25 mm.

FIG. 13-15 shows the process of joint formation without overlapping the fastening protrusions (enlarged).

The fastening clamp is made in the form of a flexible tape 1, on one end side 2 of which there are flat fastening protrusions 3 and 4.

The fastening clamp is made in the form of a flexible tape 1, on one end side 2 of which there are two pairs of flat fastening protrusions, and each pair of protrusions is made with the possibility of bending to form a bracket, while the flat fastening protrusions are located across the flexible tape and are permanently attached to it.

Flat fastening protrusions 3 and 4 in each pair are made with the possibility of bending to form brackets 5, while they are located across the flexible tape 1 and are permanently connected to it.

Flat fastening protrusions 3 and 4 can be made in the form of two flat pieces of metal tape (Fig. 3). It is preferable that the flat fastening protrusions 3 and 4 are in the form of two rectangular thin-walled plates.

The flat fastening protrusions 3 and 4 can be part of an H-shaped element cut from a thin-walled plate, in which the flat protrusions 2 are interconnected by a bridge 6 (Fig. 4).

The flexible tape 1 is preferably made of metal, preferably of sheet metal.

Flexible tape 1 can be made of plastic.

It is preferable that the fastening protrusions 3 and 4 are made of metal.

The fastening clamp preferably includes two pairs of fastening protrusions 3 and 4, the first of which is located at the end of the flexible tape 1, and the second is located behind the first pair at a distance d from it. In this case, it is preferable that the distance d between the pairs of fastening protrusions 3 and 4 is greater than the width b of the fastening protrusion 3 or 4 (the protrusions are made of equal width).

The thickness of the flexible tape t (Fig. 2) is 0.25-1.0 mm, the width B of the flexible tape is 8-40 mm, preferably 15-20 mm. The limiting values of the thickness of the flexible tape, on the one hand, are determined by the required minimum strength, and, on the other hand, by the need to ensure flexibility and the possibility of bending the tape at the joint of the clamp.

The flat fastening protrusions 3 and 4 have a width b that is 3-30 mm, preferably 5-10 mm, the total length L of each fastening element that forms the fastening protrusions 3 or 4 being 1.2-3.0 widths In the straps of the clamp, preferably up to 2.0 of the width B of the strap, so that, when folded back, the fastening protrusions 3 or 4 do not overlap, as shown in FIG. 13-14.

In the case when the bent flat projections 2 overlap each other, as shown in (Fig. 5-10), the material of the fasteners forming the fastening projections 3 or 4 is overused, and the thickness of the height of the entire collar joint increases.

The distance d between the flat fixing protrusions 3 and 4 is 5-100 mm, preferably 15-25 mm.

The thickness of the tape t (Fig. 2) is 0.25-1.0 mm, the width of the flexible tape is 8-40 mm, preferably 15-20 mm.

The fastening protrusions 3 or 4 are fixed perpendicularly on the flexible tape 1 mechanically and permanently by welding, or by notches, or by means of bulging. The fastening tabs can be made from lengths of similar tape (tape from one roll), which saves material.

The thickness h of the fastening protrusion 3 or 4 is between 0.25 and 1.0 mm, preferably between 0.4 and 0.8 mm.

It should be noted that the greater the width b of the fastening protrusion 3 or 4 and its thickness h, the greater the shear load they are able to experience, but at the same time it becomes more difficult to bend them by hand to fix the flexible tape 1.

The listed ranges of preferred clamp values were selected empirically during tests when installing thermal insulation from mineral wool mats with a thickness of 30 to 120 on pipelines with a diameter of 159 to 1020 mm. When fixing the thermal insulation 7 on the pipeline 8, the device is mounted as follows (Fig. 5-10).

The flexible tape 1 of the clamp is wrapped around the layer of thermal insulation 7, which partially wraps the pipeline 8, while the second pair of fastening projections 3 from the end 9 of the tape is bent upward (from the thermal insulation) by about 90 degrees so that a flexible tape can be passed between the bent fastening projections 3 1 (Fig. 5). After that, the aforementioned pair of fastening protrusions 3 are bent inward towards the flexible tape 1, forming a bracket 5, with a force that allows the flexible tape 7 to pass freely under it (Fig. 6).

Further, the final tightening of the thermal insulation 7 of the freely sliding flexible tape 1 under the bracket 5 formed by the fastening protrusions 3 takes place, after which the free end 10 of the tape is bent over the said bracket 5 (Figs. 7-8).

Thus, the folded flexible tape 1 cannot move relative to the folded antennae and the required size and degree of tightening is fixed.

Further, the free end of the tape 10 is placed between the first pair of fastening protrusions 4, which are bent inward over the flexible tape 1, forming a second bracket 5, which prevents the tape from jumping out of the bracket 5 formed by the second pair 3 as a result of vibration and possible spontaneous opening of the fixed clamp under the action of forces elasticity of flexible tape 1 (Fig. 8).

It is preferable that for additional fixation, further bend the remaining end of the tape in the opposite direction (Fig. 9-10).

In a similar way, a rolled roll of thermal insulation can be fixed (Fig. 11), a stack of thermal insulation mats (Fig. 12)

The process of fixation and formation of the joint 6 can be performed by one person manually without the use of special tools.

Additionally, to fix this clamp, pliers or a similar tool can be used, which can be used to additionally crimp the staples 5 at the bending points of the fastening protrusions 3 or 4, which makes it possible to increase the breaking load by about 30%.

Compared with existing analogues, a significant simplification of the design is achieved, a decrease in material consumption due to the absence of cutouts in the tapes and an increase in the reliability of the design of the fastening clamp.
