Description

Technical field

The utility model relates to building structures, in particular, to supporting adjustable structural elements of raised panel floors (raised floors).

State of the art

Known adjustable support structure (RF patent No. 2230162, priority 14.11.2003), 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 form of a square, in the corners of which are located diagonally holes 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.

The closest technical solution is the adjustable support (RF patent No. 50237, priority 04/20/2005), including the lower and upper plates, a tubular element connected at one end to the lower plate, a threaded rod with a nut, connected at one end to the upper plate. The bottom plate is made square with rounded corners, with recesses in the middle of the sides, with a central hole. The central part of the lower plate is depressed conically toward the threaded rod. The tubular element is tightly mounted on the upper

cylindrical end of the central part. Four radial stiffeners are made in the bottom plate, located crosswise at right angles to each other, starting from the tubular element, directed towards the middle of the arcuate recesses. The radial stiffeners are convex towards the tubular element. In the corners along the diagonals of the lower plate are four mounting holes, one in each corner. The upper plate is made in the form of a disk with a central hole in which the end of the threaded rod is rigidly fixed. The central part of the upper plate is pressed towards the threaded rod sequentially (in the direction from the axis of the central hole) partially with the formation of sleeve-like and disk-shaped parts. Cutouts of a P-shaped profile are made along the outer edge of the upper plate, their extended parts facing the inside of the upper plate. The cuts are arranged in a cruciform manner in pairs and are open from the outer edge, with in each pair the expanded parts of the cuts directed towards each other. Between each two adjacent cutouts are openings whose axes are parallel to the axis of the central hole. On the upper plate there are four radial stiffeners located crosswise at right angles to each other and directed by their convex part towards the threaded rod. Stiffeners begin from the sleeve-like part of the central part and end in front of the holes located between the cutouts of each pair. The threaded rod is inserted with the free end coaxially into the tubular element until the nut stops in the tubular element, while the total height of the adjustable support is set by moving the nut along the threaded rod.

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 threaded rod in the tubular element, non-optimal shape and dimensions of the lower and upper plates), 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 and the large metal consumption in its manufacture.

The purpose of the proposed utility model is to increase the reliability of the adjustable legs and reduce the metal consumption in its manufacture.

Implementation of a utility model.

Description of the design of the device illustrating a particular case of the implementation of the utility model

The figures show: the first plate 1, the first tubular element 2, the outer surface 3, the nut 4, the narrowing 5, the second tubular element 6, the second plate 7, the third end 8, the second inner surface 9, the second end 10, the fourth end 11, the first inner surface 12, first end 13, first stiffeners 14, first holes 15, first central portion 16, cutouts 17, first central hole 18, first additional protrusions 19, first outer edge 20, second holes 21, second stiffeners 22, second central part 23, second centrally e hole 24, second additional protrusions 25, second outer edge 26, annular element 27.

The adjustable support consists of two main parts: the first plate 1 in rigid connection with the first tubular element 2 and the second plate 7 in rigid connection with the second tubular element 6, and these parts are connected between

itself movably, i.e., the first tubular element 2 is screwed into the second tubular element 6 (figure 1).

The first 1 and second 7 plates in this case are made by stamping, which in this case implies the receipt of each of the elements of the first 1 and second 7 plates by their bending with the formation on one side of the protruding parts and the corresponding recesses on the opposite side.

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 first central hole 18. The first central part 16 of the first plate 1 is located around the first central hole 18, made indented towards the first tubular element 2 to a depth of more than 1.5 thicknesses of the first plate 1, within 2.5 cm from center of the first plate 1.

Eight U-shaped cutouts 17 are made along the first outer edge 20 of the first plate 1. The cutouts 17 are arranged in pairs symmetrically crosswise in two diametrical directions orthogonal to each other. The sections of the first outer edge 20, located between the cutouts 17 of each pair, are made straight.

Between the cutouts 17 of each pair is located one first hole 15; all in all, the first plate 1 has four similarly arranged first holes 15 at the same distance from the first central hole 18. In this case, all the first holes 15 have the same diameter. The axes of all the holes mentioned above (first 15, first central 18) are perpendicular to the surface of the first plate 1.

On the first plate 1 there are four identical first stiffeners 14, as well as four identical first additional protrusions 19. The first stiffeners 14 are oriented radially, arranged symmetrically, crosswise, and each of the first stiffeners 14 is located between two adjacent first holes 15 at an equal angular distance from them. In the radial direction, the first stiffening ribs 14 start from the first central hole 18 and end at the first outer edge 20 of the first plate 1.

The first additional protrusions 19 have an oblong shape and are located crosswise, symmetrically on the first stiffeners 14, with orientation in the same radial directions as they are. The first additional protrusions 19 start from the first central hole 18 and end at the point where the indentation of the first central part 16 begins.

The first stiffening ribs 14 and the first central part 16 are made in such a way that their convex parts are on one side of the first plate 1, while on its other side there are corresponding recesses, and the thickness of the first plate 1 is unchanged (Fig. 3).

The first tubular element 2 has the form of a pipe segment of circular cross section (figure 1). A thread is made on the outer surface 3 of the first tubular element 2, and its diameter is equal to the thread diameter on the second inner surface 9 of the second tubular element 6. The thread starts from the second end 10 and ends at a certain distance from the first end 13. The first tubular element 2 with its first end 13 is orthogonally connected (in this case by spot welding) with the first plate 1 from the side where the first stiffening ribs 14 are convexly facing, coaxially with the first central hole 18.

Additionally, on the first inner surface 12, there may be a longitudinal protrusion and several longitudinal recesses (in this case, three longitudinal recesses equally spaced from each other). These longitudinal recesses and protrusion can be formed, for example, due to the manufacture of the first tubular element 2 from a welded pipe.

The second plate 7 is made in the form of a rectangle with an aspect ratio in the range of 0.95-1.05, in this case it is made square and has a constant thickness (Figs. 4, 5). In the second plate 7 there is a second central hole 24. The second central part 23 of the second plate 7 is located around the second central hole 24 and is pressed annularly towards the second tubular element 6 within 3.5 cm from the center of the second plate 7, to a depth of at least half the thickness second plate 7.

Four second stiffeners 22 are made on the second plate 7, as well as four second additional protrusions 25. The second stiffeners 22 are located diagonally, crosswise symmetrically, start from the second central part 23 and end near the second outer edge 26. All second stiffeners 22 have the same sizes.

The second stiffening ribs 22, the second additional protrusions 25 and the second central part 23 are made similarly to the same elements on the first plate 1, i.e. so that their convex parts are on one side of the second plate 7, while on its other side there are corresponding recesses, while the thickness of the second plate 7 is unchanged (figure 5).

On the second plate 7, on the side where the recesses of the second stiffening ribs 22 are located, around the second central hole 24, an annular element 27 is formed which gives the second plate 7 additional rigidity.

The second additional protrusions 25 have an oblong shape and are located on the second central part 23 with an orientation in the same radial directions as the second stiffening ribs 22.

On the second plate 7, between the second outer edge 26 and the second central part 23, there are eight second holes 21. The second holes 21 are arranged in pairs symmetrically on either side of each of the second stiffeners 22. All of the second holes 21 are located at the same distance from the second central hole 24 closer to the second outer edge 26. In this case, the second holes 21 have the same diameter. The axis of the holes (second 21, second central 24) are perpendicular to the surface of the second plate 7.

The second tubular element 6 is made in the form of a piece of pipe of circular cross section (figure 1). Its fourth end 11 is made with a narrowing 5 (i.e., has a smaller diameter than the rest of the second tubular element 6). In the place of narrowing 5 on the second inner surface 9 is a thread. Additionally, on the second inner surface 9 may be a longitudinal protrusion (if, for example, the second tubular element 6 is made of a welded pipe). The second tubular element 6 by the third end 8 is orthogonally connected (in this case by spot welding) to the second plate 7 from the side where the second stiffening ribs 22 are convexly facing, coaxially with the second central hole 24.

The nut 4 is screwed onto the first tubular element 2 and can be used to pre-indicate the necessary position of the first tubular element 2 relative to the second tubular element 6 (Fig. 1).

The dimensions of the first 1 and second 7 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. In this case, the area of the second plate 7 is approximately equal to the area of the first plate 1, which is due to the use of raised floor plates of a certain type.

The lengths of the first 2 and second 6 tubular elements are selected so that the second tubular element 6 can be screwed into the first tubular element 2 almost completely; in addition, the size of the height adjustment range of the adjustable support is taken into account. In this case, the length of the second tubular element 6 is equal to the length of the threaded portion of the first tubular element 2.

To facilitate the perception in FIG. 1, the connections of the first plate 1 with the first tubular element 2, as well as the second plate 7 with the second tubular element 6 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). For this, the second plate 7 with the second tubular element 6 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 21 with fasteners (for example, nails, screws, etc.).

Previously, the nut 4 on the first tubular element 2 is installed in a place to which the first tubular element 2 must be screwed into the second tubular element 6 to provide the necessary height of the adjustable support. The first tubular element 2 with the first plate 1 is brought up from above to the fourth end 11 of the second tubular element 6, having a narrowing 5, and screwed into it by the second end 10, thereby forming a connection on the thread of the first inner surface 12 and outer surface 3. Thus, the first the tubular element 2 with the first plate 1 and the second tubular element 6 with the second plate 7 form an adjustable support in connection (Fig. 1).

The achievement of the required total height of the adjustable support is established by screwing / unscrewing the first tubular element 2 in the second tubular element 6. In this case, the orientation of the first plate 1 can be set by turning it so that the location of the first holes 15 and cut-outs 17 is suitable for fasteners and protruding parts of raised floor parts ( plates, beams, etc.) fixed further on the first plate 1. After setting the required height of the adjustable support and orientation of the first plate 1, the position of the first tube of that element 2 can be fixed from further screwing with nut 4. Similarly, any necessary quantity can be set and fixed

adjustable legs, the height of each adjustable legs can be set separately.

Implementation of a utility model of an adjustable support with the totality of all these features (the design of the first plate 1 (disk shape, mutual arrangement of the first holes 15, cutouts 17, the presence of the first central part 16, first stiffeners 14, first additional protrusions 19) in combination with in this manner by connecting the first tubular element 2 with the first plate 1; the second plate 7 is in the form of a square with a second central part 23 pressed in, second stiffeners 22, second holes 21, second additional protrusions 25 in combination with the connection of the second tubular element 6 with the second plate 7 made in this manner; the presence of a nut 4, the described aspect ratio of the parts of the adjustable support) leads to an optimal load distribution on the adjustable support, increases its rigidity, resistance to loads, simplifies the adjustment process her heights. In general, a combination of all of the above features provides increased reliability of the adjustable support and reduces the metal consumption in its manufacture.
