State of the art

Known adjustable support structures (RF patent No. 55820, priority 11.04.06, RF patent No. 56435, priority 14.04.06), consisting of a lower and upper plate, a tubular element, one end connected to the lower plate, a threaded stand, one end connected to the upper plate, and the threaded stand is screwed into the tubular element. Known adjustable support structure (RF patent No. 2230162, priority 11/14/03), including the lower and upper plates, a tubular element connected at one end to the lower plate, a threaded stand with a nut and locknut, one end connected to the upper plate. The bottom plate is made in the shape of a square, in the corners of which there are diagonally openings for fasteners. The upper plate is made in the form of a disk, along its perimeter, pairs of slots open from the peripheral part of the plate are located crosswise, holes for fixing elements are placed between adjacent slots. The free end of the threaded stand is installed with the possibility of axial movement in the cavity of the tubular element. The lower and upper plates are made with a Central hole for placement in it, followed by rigid connection with the plates of the ends, respectively, of the tubular element and the threaded stand. Around each hole there is a recess, the depth of which does not exceed the thickness of the plate, while the convex surfaces of the recesses of the upper and lower plates are facing towards each other. The height of the adjustable support structure is set by moving the nut on the threaded stand, followed by fixing the position of the nut with a lock nut.

An adjustable support is also known (RF patent No. 2278227, priority 03/14/2005), including the lower and upper plates, a tubular element connected at one end to the lower plate, a threaded rod connected at one end to the upper plate. The support includes a stand consisting of

a cylindrical threaded rod rigidly connected at one end to a round perforated base plate, and a tubular element, one end of which is rigidly connected to a round support plate, and the other end having a smoothly tapering section with an internal thread interacts with the threaded rod. The base plate is made in the form of a disk with a cup-shaped recess in the center having a flat bottom with an opening for passing the upper end of the tubular element protruding from the plane of the concave surface of the cup-shaped recess facing the floor. Along the perimeter of the disk of the base plate, identical figured grooves open from its peripheral part are located. Between the figured grooves, receiving platforms are formed. The perforated base plate is made with an annular groove surrounding a threaded cylindrical rod. A convex zone in the form of an eight-pointed star in plan with rounded ends of the beams, between which the holes are located, is formed on the outer side of the groove. A protrusion is made on the lower side of the base plate coaxially with the threaded rod, while the protrusion base, the lower surface of the groove and the base plate portions free from the annular zone are located in the same horizontal plane and are in contact with the surface on which the support is to be mounted.

The closest technical solution is an adjustable support (application No. 2006144594 from 12/14/06) containing the second and first plates equipped with a threaded rod and a tubular element respectively screwed into one another. The first plate is made in the form of a disk with a first central hole. The tubular element is connected by the first end to the first plate in its central part so that its axis coincides with the axis of the first central hole in the first plate. On the perimeter side of the first plate, eight cutouts are made, as well as first openings and second openings located through one between the openings so that the axes of the first and second openings are parallel to the axis of said first central opening. The central part of the first plate is pressed toward the tubular element to a depth of more than half the thickness of the first plate. In the second central hole of the second plate, the third end of the threaded rod is placed so that its axis is orthogonal to the second plate, and the tubular element is made narrower towards the second plate. The length of the tubular element is more than 0.1 of the diameter of the first plate. The second plate is made in the form of a disk with a concentric second outer edge, and then to the center of its second annular protrusion, an annular recess, the first annular protrusion, as well as radially extending from the second annular protrusion

stiffeners passing between the third holes towards the second outer edge. The first and second plates are stamped from coated sheet metal, the surface areas of the second plate from the side opposite the threaded rod in the zone of the annular recess, the third holes and the specified second outer edge are located in the same plane. The design of the adjustable support described above allows you to adjust (or, if necessary, level) the height of the raised floor. However, due to insufficient study of individual structural elements and their connections (insufficiently reliable fixation of the position of the threaded rod on the tubular element, suboptimal shape and dimensions of the base plate and base plate), the design as a whole does not have sufficient reliability and durability during operation.

A disadvantage of the known technical solution is the low reliability of the adjustable support during operation.

The purpose of the proposed utility model is to increase the reliability of the adjustable support.

The adjustable support consists of two main parts: the first plate 1 in rigid connection with the threaded rod 2 and the second plate 11 in rigid connection with the tubular element 13, and these parts are movably connected to each other, i.e. the threaded rod 2 is screwed into the tubular element 13 (figure 1).

The first plate 1 and the second plate 11 of the adjustable support in this case are made by stamping, which implies the receipt of each of the elements (excluding the first 5, second 10, first 16 and second 22 central holes) of the first 1 and second 11 plates with their bend with the formation on one the side of the protruding parts and the corresponding recessed parts on the opposite side. Material

of which the first 1 and second 11 plates are made, in this case is coated sheet metal.

The first plate 1 is made in the form of a disk of constant thickness (figure 2, 3). In the first plate 1 there is a round first central hole 16 (hereinafter, round is understood to mean openings in the shape of a straight round cylinder having a cross-section in the section orthogonal to the axis of the tubular element 13 or threaded rod 2).

The Central part 4 of the first plate 1 is located around the first Central hole 16, made indented towards the threaded rod 2.

Around the first central hole 16, in the direction from it to the first outer edge 15 of the first plate 1, there is a first annular protrusion 17. The first annular protrusion 17 is directed by its convexity towards the threaded rod 2. In the section orthogonal to the surface of the first plate 1, the surface of the first annular the protrusion 17 facing the threaded rod 2 has the shape of a half circle. The first annular protrusion 17 is made so that on the opposite side of the first plate 1, facing away from the threaded rod 2, there is a first annular recess 18 corresponding to the first annular protrusion 17, while the thickness of the first plate 1 is unchanged (figure 3). The height of the first annular protrusion 17 in this case is 1 mm.

The first holes 5 are located between the central part 4 and the first annular projection 17. The first holes 5 are located with the same angular distance between each two adjacent first holes 5. In total, on the first plate 1 there are four similarly located first holes 5 at the same distance from the first outer edge 15 The axes of the first holes 5 are parallel to the axis of the first central hole 16. The centers of the first holes 5 are located at the same distance from the center of the first plate 1.

In this case, the diameter of the first plate 1 is 60 mm, its thickness is 3 mm; the diameter of the first central hole 16 is 10 mm. The ratio of the thickness of the first plate to its diameter is from 1:24 to 1:36 (in this case, this ratio is 1:30). The diameter of the Central part 4 is 16 mm, the depth of the depression of the Central part 4 is 1 mm. All the first holes 5 are made round and have the same diameter of 6 mm, the distance between the center of the first plate 1 and their centers is 14 mm.

The threaded rod 2 is inserted by the first end 3 into the first central hole 16, is rigidly orthogonally attached to the first plate 1 in its center so that its axis is orthogonal to the first plate 1 (Fig. 1). (By the end face is meant the end part of the threaded rod 2, i.e., the end surface itself together with the adjacent part of the material of the threaded rod 2). In this case, the threaded rod 2 is attached to the first plate 1, followed by the flaring of its first end 3 from the side of the first plate 1, where the first annular recess 18 is located. The length of the threaded rod 2 is 56 mm, diameter 12 mm. The ratio of the diameter of the first plate 1 and the diameter of the threaded rod 2 is from 4: 1 to 6: 1 (in this case, this ratio is 5: 1). The ratio of the length of the threaded rod 2 and the diameter of the first plate 1 is from 3.8: 1 to 5.6: 1 (in this case, this ratio is 14: 3).

The second plate 11 is made in the form of a disk and has a constant thickness (4, 5). The ratio of the diameters of the second plate 11 and the first plate 1 is from 1.3: 1 to 2: 1. In this case, the diameter of the second plate 11 is 100 mm, its thickness is 3.5 mm, the ratio of the diameters of the second plate 11 and the first plate 1 is 5: 3.

In the second plate 11 there is a second central hole 22. In this case, the second central hole 22 is round, its diameter is 16 mm.

On the second plate 11, around the second central hole 22, there is a second annular protrusion 24 directed by its convexity towards the tubular element 13. In a section orthogonal to the surface of the second plate 11, the surface of the second annular protrusion 24 facing the threaded rod 2 has the shape of a half circle. The height of the second annular protrusion 24 in this case is 1.5 mm.

The second annular protrusion 24 is surrounded by a second annular recess 23, which has an annular shape in the orthogonal axis of the second central opening 22 of the cross section. The bottom 26 of the second annular recess 23 is in the form of a flat ring, and the plane of the bottom 26 is also orthogonal to the axis of the second central hole 22.

Around the second annular recess 23, in the direction from it to the second outer edge 19, there is a third annular protrusion 25 directed by its convexity towards the tubular element 13. In a section orthogonal to the surface of the second plate 11, the third annular protrusion 25 has a half-ring shape (behind

excluding sections from which stiffeners 20). The height of the third annular protrusion 25 in this case is 1.5 mm.

On the second plate 11, eight stiffeners 20 are identical in shape and size. The stiffeners 20 are in the form of elongated protrusions with rounded ends 21. The stiffeners 20 are radially arranged, and the angular distance between any two adjacent stiffeners 20 is the same. The ribs 20 extend from the third annular protrusion 25 in the direction of the second outer edge 19, end from it at a distance of approximately equal to 5 mm They are directed by their bulges towards the tubular element 13. In this case, between the stiffeners 20, the third annular protrusion 25 and the surface of the second plate 11, facing the tubular element 13, there are clear transition boundaries (Fig. 4), in other cases, these transitions can be made smooth.

In this case, the depth of the stiffeners 20 from the side opposite to the tubular element 13 is 1.5 mm, and their length (measured from the point of transition of the third annular protrusion 25 into the stiffeners 20 to the farthest point of the rounded end 21) is 16 mm.

In the second plate 11 there are eight round second holes 10 located at the same distance from its center, between the third annular protrusion 25 and the second outer edge 19. Each of the second holes 10 is located between two adjacent stiffening ribs 20, at an equal angular distance from them. In this case, the second holes 10 have the same diameter of 12 mm. The axis of the second holes 10 and the second Central hole 22 are parallel to the axis of the threaded rod 2.

The stiffening ribs 20, the second 24 and the third 25 annular protrusions are made so that their convex parts are located on one side of the second plate 11, facing the tubular element 13, and on the opposite side of the second plate 11 there are corresponding recesses, while the thickness of the second plate 11 is unchanged (figure 5). The surface portions of the second plate 11 from the side opposite to the tubular element 13 located in the region of the second annular recess 23, the second holes 10 and the second outer edge 19 are located in the same plane.

The tubular element 13 has the form of a pipe segment of circular cross section (figure 1). A thread is made on the inner surface 8 of the tubular element 13, and its diameter is equal to the thread diameter of the threaded rod 2. The tubular element 13 is made with a narrowing 14 in the direction of the first plate 1 (i.e., with a smaller outer diameter than the rest of the tubular element 13 on the inner surface 8 of the tubular 13 at the site of the narrowing 14, starts from the first end 6 and ends at the transition of the narrowing 14 to the rest of the tubular element 13. The tubular element 13 is missed in its second end 12 to the second central from The hole 22 is orthogonally connected (in this case by welding, Fig. 9 shows the weld seam) to the second plate 11 so that its axis coincides with the axis of the first central hole 16, from the side where the protrusions of the second 24 and third 25 ring protrusions of the second plates 11.

In this case, the length of the tubular element 13 is 50.5 mm, its outer diameter is 16 mm, the length of the narrowing 14 is 18 mm, the outer diameter of the narrowing 14 is 14.2 mm.

Additionally, on the inner surface 8 of the tubular element 13 there may be longitudinal protrusions (in this case, there is one longitudinal protrusion, not shown in the figures). This longitudinal protrusion can be formed, for example, due to the manufacture of the tubular element 13 from a welded pipe.

To facilitate the perception of the drawings in FIG. 1, the connection of the first plate 1 with the threaded rod 2, as well as the welded connection of the second plate 11 with the tubular element 13 are shown conditionally, in FIGS. 2-5 a part of the identical designations is not affixed.

Operation of a device illustrating a particular case of a utility model implementation

The device operates as follows. The adjustable support should be installed, as a rule, vertically (hereinafter, vertical refers to the direction parallel to the gravity vector, horizontal refers to the direction perpendicular to it, the direction from top to bottom is assumed to coincide with the direction of the gravity vector). The second plate 11 with the tubular element 13 rigidly attached to it is installed in a predetermined place of the base (for example, the subfloor) and is attached to it through the second holes 10 with fastening elements (for example, nails, screws, screws, etc.).

The dimensions of the first 1 and second 11 plates are selected so as to ensure good stability of the adjustable support and reliable fastening to it of the upper structural elements of the floor. The lengths of the tubular element 13 and the threaded rod 2 are selected so that the threaded rod 2 can be screwed into the tubular element 13 by taking into account the size of the height adjustment range of the adjustable support.

The threaded rod 2 with the first plate 1 by the second end 7 is brought up from above to the first end 6 of the tubular element 13 and screwed into it by the required amount so that the second end 7 is located inside the tubular element 13. Thus, the threaded rod 2 with the first plate 1 and tubular the element 13 with the second plate 11 form an adjustable support in connection (figure 1).

The achievement of the required total height of the adjustable support is established by screwing / unscrewing the threaded rod 2, respectively, to / from the tubular element 13. In this case, the orientation of the first plate 1 can be set by turning it so that the location of the first holes 5 is suitable for fasteners and protruding parts of the raised floor parts (plates, beams, etc.) fixed further on the first plate 1. Similarly, any necessary number of adjustable supports can be fixed and fixed, and the height of each The support can be set separately. The guide profiles are inserted into the first holes 5 of the first plate 1 and fixed in them. Subsequently, raised floor plates are laid on the first plates 1 of the adjustable supports and guide profiles.

The described mutual arrangement of the first holes 5, the first annular protrusion 17 and the corresponding first annular recess 18, the execution of the Central part 4 of the first plate 1 curved helps to optimally distribute the load on the first plate 1 and maintain the shape and size of the first plate 1.

The execution of the second plate 11 in the form of a disk, with a second annular protrusion 24, with stiffening ribs 20 made extending from the third annular protrusion 25, contributes to the uniform distribution of loads on the second plate 11, increases its rigidity and reliability of fastening to the floor. The location in the same plane of the surface areas of the second plate 11 from the side opposite the tubular element 13, in the area of the second annular recess 23, the second holes 10 and the second outer edge 19 contributes to better stability of the adjustable support, while increasing the uniformity of load transfer from the adjustable support to

the basis on which it is fixed.

Implementation of a utility model of an adjustable support with the combination of all these features (the design of the first plate 1 in the form of a disk with a first central hole 16, the first annular projection 17, the relative position of the first holes 5, the presence of a convex central part 4, the design of the second plate 11 in the form of a disk with a second a Central hole 22, with a second 24 and third 25 annular protrusions and a second annular recess 23 between them, with the second holes 10, with stiffeners 20) in combination with the connection m threaded rod 2 with a first plate 1; with the connection of the tubular element 13 with the second plate 11 made in this way, the described aspect ratio of the parts of the adjustable support leads to an optimal load distribution on the adjustable support, increases its rigidity, and resistance to loads.

In general, a combination of all of the above features of the adjustable support design provides increased reliability of the adjustable support.
