Description

FIELD OF TECHNOLOGY TO WHICH A USEFUL MODEL IS

This utility model relates to the field of building construction. In particular, it relates to apparatus for fixing an object to a building structure.

DESCRIPTION OF THE PRIOR ART

In various cases, objects such as plates (panels) or drywall construction profiles (dry plaster) are fixed to a building structure, such as a ceiling, at a distance from the building structure.

Panel fitting to the building structure is usually provided by two nuts, each on a different side of the panel.

This fixation is unfavorable, because one of the nuts is located behind the panel. The method described above also does not provide a satisfactory solution for long cardboard, necessary for convenient fixation of objects at a distance from the building structure.

Known fastener containing a threaded portion located on the first axial end of the fastener, and a head located on the second axial end of the fastener and containing a cavity and at least one groove channel located on the outer surface of the side wall of the head, as well as the installation a tool containing a rod, a handle located on the first axial end of the rod, a tip located on the second axial end of the rod, and at least one protrusion connected to the rod and made , with the possibility of placement in the corresponding groove channel to hold the fastener on the tip. The specified protrusion is made with the possibility of movement in the axial and radial directions, which allows you to enter the specified protrusion into the corresponding channel from these grooved channels (see application for invention of the Russian Federation No. 2013113713 from 08/26/11, IPC F16B 23/00).

The known solution allows you to hold the fastener on the tip during operation and can lock the head of the fastener on the tip. However, in long-sized objects, the use of such a design does not provide convenient fixation when working at a distance from the building structure.

The closest technical solution of the known is a tool for tightening a screw, which includes a drive means and a long end portion containing a tube, the diameter of which can accommodate at least the first screw head. The front end is open in an outer direction relative to the end portion and includes an engagement portion suitable for gripping the first screw head. Between the front end and the tube engaging portion, elastic means are arranged for contacting the portion of the cylindrical supporting surface of the screw, allowing part of the first screw head to be inserted into the portion of the engagement of the tube. A storage chamber is connected to the engagement portion with a means for opening and closing the chamber, which can accommodate at least one separated first screw head.

This tool can be used in conjunction with a screw having between its front and rear ends a first polyhedral head, a brittle neck, a second polyhedral head and a threaded rod (see RF patent No. 2145393 dated January 16, 1996, IPC F16B 23/00).

The known device allows you to dispose of the first screw head after cutting the neck.

However, in such cases, when the structures of the installation objects are large plates or panels, it is difficult to dispose of the sheared screw head. In addition, the use of a tool to fix the object to the building structure at an acceptable distance with the ability to adjust it using two nuts seems unnecessarily costly.

One of the aspects of this utility model is the provision of equipment for convenient fixation of objects at a distance from the building structure.

The subject of this utility model is also the provision of solutions to the above and other problems of the prior art.

Other objects and advantages of the utility model will be more apparent in its description.

ESSENCE OF A USEFUL MODEL

The present utility model describes a nut 10 comprising:

- the internal threaded portion 34 for screwing the bolt 14 into it;

- a head 52 surrounding the threaded portion 34 as the housing of the threaded portion 34, with the rotation of the bolt 14 relative to the inner threaded portion 34; and

- a self-cutting thread 36 for screwing the nut 10 through the object 18, where the self-cutting thread 36 does not provide a linear step with respect to the object 18 when rotating between them to complete screwing, and the self-cutting thread 36 may include an internal threaded part 34 for screwing the bolt 14 into it, thereby allowing the nut 10 to be attached to the object 18, while moving the bolt 14 relative to the object 18 either by rotating the bolt 14 relative to the nut 10, or by rotating the nut 10 relative to the object 18, thereby allowing fixing Object 18 to building structure 20 at an acceptable, adjustable distance of 40.

A characteristic feature of the self-tapping thread 36 is that, without providing a linear step relative to the object 18 when rotating between them to complete screwing, it may contain a space 48 between the inner connecting end 44C of the self-tapping thread 36 and the adjacent surface 38 of the nut 10, and the space 48 is substantially greater than the thickness 84 of the object 18, which allows the object 18 to rotate inside the space 48.

The nut 10 may further comprise an elastic gasket 46 located in the space 48 to limit movement between the self-tapping thread 36 and the object 18 when screwing between them is completed.

A characteristic feature of the self-tapping thread 36 is that, without providing step linearity with respect to the object 18 when rotating between them at the completion of screwing, it may contain an internal connecting (conjugated) element 44C, which is thinner than other connecting elements 44B, while rotating nuts 10 relative to the object 18 in the locking direction 64, the bend 88 in the hole 54 of the object 18 bends the end 90 of the inner element 44C, thereby moving the bend 88 of the object 18 from the groove 86 between the self-tapping elements 44 B, 44C a common thread 36. According to one aspect, the present utility model is directed to creating a tool 60 that can be implemented by screwing the bolt 14 into the nut 10 while rotating in the locking direction 64 and to release the bolt 14 from this when rotating in the opening direction, wherein 60 contains two elements interconnected, one 22 of which interacts with the specified bolt 14, and the other 28 is connected to the rotation drive, while it contains the first internal thread 62 for screw part in it with the external thread 66 of the bolt 14 and the clamping element 32 located between the indicated elements, compressing the external thread 66 of the bolt 14 outside the specified internal thread 62, thereby ensuring fixation between them.

The clamping tool 60 may further comprise:

- a section with an external thread 42 for compressing the clamping element 32; and

- the second internal thread 68 corresponding to the external thread 42, where the step 70 of the thread 42 and the internal thread 68 is much larger than the thread step 66 of the bolt 14, thereby opening the external thread 42 from the second internal thread 68 to release the clamping member 32 until the bolt is released fourteen.

DESCRIPTION OF USEFUL MODEL

A true utility model will be apparent from a detailed description of preferred embodiments of the utility model (“best modes”) that are not restrictive. For brevity, some well-known features, methods, systems, procedures, components, circumstances, etc. not described here in detail.

Figure 1 presents a variant of the prior art of a self-tapping threaded nut and a panel into which the nut is screwed.

The term "self-tapping thread" refers here to a thread having an expanded perimeter for creating a thread in an object by screwing a self-tapping thread into this object.

The term "self-tapping nut" means here a nut having a tapping thread. A prior art embodiment of a self-tapping nut includes a self-tapping thread in which, with the exception of the outer tie member 44A, the width 80 of all binders, including the inner tie member 44D and the central tie members 44B, are substantially equivalent; and the width 92 of each groove 86 between the connecting elements is essentially equal to the width 80 of the connecting elements.

The inner connecting element 44D reaches the surface 38 of the head 52.

When a self-tapping thread is inserted into the prepared hole 54 (shown in FIG. 3) of the panel 18 having a thickness 84 substantially equivalent to the width 92 of the groove 86, the external connecting element 44A provides a local bend 88, which is further increased by the central connecting elements 44B.

Bend 88 enters groove 86 between members 44A, 44B, and 44D, and tapping leads to either locking the nut before the last coupling member 44D comes into contact with surface 38 or the seal, or opening the thread.

In FIG. 2 shows a self-tapping nut described in this utility model and a panel into which a nut is screwed.

In contrast to the conventional self-tapping thread, the internal connecting element 44C of the self-tapping thread 36 of the nut 10, in accordance with the present utility model, does not reach the surface 38 of the head 52. There is no end to the self-tapping thread 36, i.e. there is a space 48 along the entire width of the thread between the inner element 44C of the thread 36 and the surface 38 of the head 52.

The formation of space 48 is associated with a thinner inner element 44C of nut 10 compared to elements 44B.

By inserting a self-tapping thread 36 into the corresponding hole 54 (shown in FIG. 3) of the panel 18 having a thickness of 84, essentially like the groove 86, the external connecting element 44A provides a local bend 88 of the panel 18, which is further increased by the central connecting elements 44B.

The bend 88 is inserted into the groove 86 between the elements 44A, 44B and 44C, and threading leads to a linear movement of the clamping nut 10. When the bend 88 reaches the space 48, the linear movement stops.

Since the inner bonding element 44C is relatively thin, when the nut 10 is further clamped, the bend 88 of the panel 18 bends the end 90 of the inner bonding element 44C. Thus, the connecting element 44C no longer leads to a bend 88 of the panel 18 into the groove 86, even when the nut 10 rotates to open.

Thus, the nut 10 is rotatable relative to the panel 18, even though the nut 10 is not exempt from the profile 18.

FIG. 3 is a perspective view of the nut of FIG. 2 and a metal panel or profile for fixing a bolt therein.

The nut 10 preferably includes an elastic gasket 46 located in the space 48 between the inner connecting member 44C of the self-tapping thread 36 and the surface 38 of the head 52. The elastic gasket 46 is used to limit movement between the self-tapping thread 36 and the panel / object 18 when screwing in between is completed. Restriction of movement avoids vibration.

The nut 10 includes an internal thread 34 for screwing into it a bolt 14 having an external thread 66 corresponding to the thread 34; a head 52 including a plurality of surfaces 50, such as hexagonal surfaces, for rotating the nut 10; self-tapping thread 36 for bending 88 shown in FIG. 1 and 2, in the prepared hole 54 of the panel or profile 18. The self-tapping thread 36 is hollow and includes an internal thread 34 that allows the bolt 14 to be inserted through it, as shown in FIG. four.

In FIG. 4 shows the first, second and third steps for fixing the profile of FIG. 3 to the wall or ceiling by means of the nut of FIG. 3.

In the first step, the installer fixes the nut 10 on the profile 18. As explained in FIG. 3, nut 10 rotates freely relative to profile 18, even though nut 10 usually does not have the ability to be free of profile 18.

In a second step, the installer fixes the wall sleeve 16 to the ceiling 20, or to the wall, or to another building structure.

In a third step, the installer wraps the thread 66 of the bolt 14 in the internal thread 34 of the nut 10 (see FIG. 3) with respect to the nut 10. While screwing the bolt 14 into the nut 10, the head 52 of the nut 10 should be supported by a wrench 56. Typically, gaskets 46 may be sufficient so as not to use a wrench 56 to prevent rotation of the nut 10 in this case. The installer further rotates the bolt 14 into the wall sleeve 16 until it is locked.

At the end of the third stage, the bolt 14 does not allow the distance 40 to change between the wall or ceiling 20 and the profile 18, because the bolt 14 no longer has the ability to rotate. In FIG. 5 shows the fourth step of adjusting the distance from the profile to the wall or ceiling of FIG. four.

In the fourth step, the installer rotates the nut 10 relative to the bolt 14 (which can no longer rotate) to adjust the distance from the profile 18 to the ceiling 20.

At the fifth stage, the installer can divert the drive from the bolt 14 and can clip the remainder of the bolt 14.

In FIG. 6 shows a tool for rotating a long bolt and for subsequently releasing this bolt from the tool.

A unidirectional rotary tool 60 may clamp the bolt 14 as it rotates, directing it toward the ceiling; and can release the bolt 14 when “trying” to turn the bolt with the unidirectional tool 60 in the opposite direction. The electric rotary drive 78 can rotate the lower element 28 of the unidirectional rotary tool 60 through the hexagonal element 30 of the lower element 28.

In FIG. 7 is an exploded view of the tool of FIG. 6.

The external thread 72 of the hexagonal element 30 is constantly fixed to the internal thread 74 of the lower element 28.

When the hexagonal element 30 is rotated toward locking, as shown by arrow 64, the external thread 66 of the bolt 14 enters the internal thread 62 of the upper element 22 of the tool 60.

The external thread 66 of the bolt 14 and the internal thread 62 of the upper element 22 of the compression tool 60 are sealed relative to each other by the compression element 32, clamped by the lower element 28.

The rotation of the lower element 28 rotates the external thread 42 in the internal thread 68 of the upper element 22.

This rotation of the lower element 28 also compresses the central element 32, referred to above as the "compression element".

The central element 32 compresses the external thread 66 of the bolt 14 outward relative to the internal thread 62 of the upper element 22 of the tool 60, thereby providing engagement between them, thereby making separation between them difficult.

In addition to this difficulty, when the hexagonal element 30 is rotated against the arrow 64, the external thread 42 opens relative to the internal thread 68 before the external thread 66 of the bolt 14 opens relative to the internal thread 62 of the upper element 22; this happens because the pitch 70 of the threads 42 and 68 is significantly larger than the pitch of the threads 66 and 62.

Thus, threads 68 and 42 have a lighter opening degree, as the threads 42 and 68 have a shorter engagement length and an area between them than the engagement length and the corresponding region of the threads 66 and 62. Thus, the threads 42 and 68 open one from another by less force than any other threads in the system, and thus open first.

In FIG. 8 shows the tool of FIG. 7 in the assembly state.

In FIG. 9 shows a section through the tool of FIG. 7, including the nut and bolt of FIG. 3.

The opening of the thread 42 of the lower element 28 from the thread 68 of the upper element 22 does not separate the lower element 28 from the upper element 22, due to the fact that the protrusion 24 of the lower element 28 and the protrusion 26 of the upper element 22 block each other.

The opening of the thread 42 of the lower element 28 from the thread 68 of the upper element 22 releases the compression of the external thread 66 of the bolt 14 in the direction of the internal thread 62 of the upper element 22 by the central element 32, thereby releasing the bolt 14.
