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 are made in the bottom plate

radial stiffeners 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, with their expanded 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, and in each pair, the expanded parts of the cuts are 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 coaxially with the free end 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.

Utility Model Implementation

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

In the figures, in ascending order of numbers clockwise, are indicated:

the first plate 1, the first tubular element 2, the first inner surface 3, nut 4, the second tubular element 5, the outer surface 6, the second inner surface 7, the second plate 8, the third end 9, the second end 10, the narrowing 11, the fourth end 12, the first end 13, the first stiffening ribs 14, the first holes 15, the second holes 16, the troughs 17, the cutouts 18, the first central hole 19, the second stiffening ribs 20, the first outer edge 21, the third holes 22, the third stiffening ribs 23, the fourth holes 24 , additional protrusions 25, the second central hole Section 26, second outer edge 27, fourth stiffeners 28, annular element 29, recesses 30.

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 8 in rigid

connection with the second tubular element 5, and these parts are interconnected movably, with the possibility of separation, on the thread (figure 1).

The first plate 1 is made in the form of a disk of constant thickness. In the first plate 1 there is a first central hole 19 (figure 2). Eight U-shaped cutouts 18 are made along the first outer edge 21 of the first plate 1. The cutouts 18 are arranged pairwise symmetrically crosswise in two diametrical directions orthogonal to each other. Between the cutouts 18 of each pair, a U-shaped deflection 17 is made (in Fig. 2, the deflections 17 are shown for simplification of perception with two distinct contours, although in this case, the deflections 17 are smooth).

Also, between the cutouts 18 of each pair, one first hole 15 is located; in total, on the first plate 1 there are four first openings 15 similarly located at the same distance from the first central hole 19. Between each nearest pair of cutouts 18, one second hole 16 is located at an equal angular distance from them; in total, on the first plate 1 there are four second holes 16 All second holes 16 are located at the same distance from the first central hole 19 and closer to it than the first holes 15. In this case, all first holes 15 have the same diameter, the second holes The holes 16 also have the same diameter, the diameter of the first holes 15 being smaller than the diameter of the second holes 16. The axes of all the holes mentioned above (first 15, second 16, first central 19) are perpendicular to the surface of the first plate 1.

On the first plate 1 there are four identical first stiffeners 14 and four identical second stiffeners 20. Each of the first stiffeners 14 is located between the first hole 15 and the first Central hole 19 at a distance from them and is oriented along the radius. The first stiffening ribs 14 begin between the first central bore 19 and the first end 13 of the first tubular element 2. Each of the second stiffening ribs 20 is radially oriented between the second bore 16 and the first central bore 19 away from the first central bore 19; wherein the second hole 16 is located at the end of the second stiffener 20 facing the first outer edge 21. The second stiffeners 20 begin between the first central hole 19 and the first end 13 of the first tubular element 2.

The first 14 and second 20 stiffeners, as well as deflections 17 are made in such a way (Figs. 2, 3) that their convex parts are located on one side of the first plate 1, while on its other side there are corresponding recesses 30, i.e. thickness

the first plate 1 is unchanged (for example, the first 14 and second 20 stiffeners and deflections 17 can be performed by stamping.)

The first tubular element 2 has the form of a pipe segment of circular cross section. The first end 13 is made with a narrowing 11 (i.e., has a smaller diameter than the rest of the first tubular element 1). At the site of narrowing 11, a thread is made on the first inner surface 3. Additionally, on the first inner surface 3 may be a longitudinal protrusion (if, for example, the first tubular element 1 is made of a welded pipe). The first tubular element 1 by the second end 10 is orthogonally attached (in this case by spot welding) to the first plate 1 in its center from the side where the first 14 and second stiffeners 20 are convex, coaxially with the first central hole 19.

The second plate 8 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. In the second plate 8 there is a second central hole 26 (Fig.3).

Four third stiffening ribs 23 and four fourth stiffening ribs 28, as well as eight additional protrusions 25 are made on the second plate 8. The third stiffening ribs 23 are oriented diagonally, start between the second central hole 26 and the third end 9 of the second tubular element 5, and end near the second outer edges 27. All third stiffeners 23 have the same dimensions.

Each of the fourth stiffeners 28 is located between two adjacent third stiffeners 23, at an equal angular distance from them. The fourth stiffeners 28 begin between the second central hole 26 and the third end 9 of the second tubular member 5, end at the second outer edge 27, and there may be bends on the second outer edge 27 resulting from the fourth stiffeners 28. All fourth stiffeners 28 have the same size.

The third 23 and fourth 28 stiffeners, as well as additional protrusions 25 are made in such a way, their convex parts are located on one side of the second plate 8, while on its other side there are corresponding recesses 30, i.e. the thickness of the second plate 8 is unchanged.

On the diagonal directions of the second plate 8, between the second outer edge 27 and the third stiffeners 23, at the same distance from the second outer edge 27, there are four third openings 22. Each of the third openings 22 is located at the end of the corresponding third stiffener 23 facing towards

the second outer edge 27. The fourth holes 24 are arranged in pairs symmetrically on both sides of one of the pairs of diametrically opposite fourth stiffeners 28. All fourth holes 24 are located at the same distance from the second central hole 26, closer to it than the third holes 22. In this case third 22 and fourth holes 24 have the same diameter. The axis of the holes (third 22, fourth 24, second central 26) are perpendicular to the surface of the second plate 8.

The central part of the second plate 8 is pressed within 3.5 cm from the second central hole 26 towards the second tubular element 5 to a depth of more than 1.2 thicknesses of the second plate 8 so that from its side, where the recesses 30 of the stiffeners are located, an annular element is formed 29 (Fig. 5).

The second tubular element 5 is made in the form of a pipe segment of circular cross section. A thread is made on the outer surface 6 of the second tubular element 5, and its diameter is equal to the thread diameter on the first inner surface 3 of the first tubular element 1. The thread starts from the third end 9 and ends at a certain distance from the fourth end 12. The second tubular element 5 with its fourth end 12 is orthogonally connected to the second plate 8 from the side where the third 23 and fourth stiffeners 28 are facing with the convex parts, coaxially with the second central hole 26. Additionally, on the second inner surface spans 7 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 second tubular element 5 from a welded pipe.

The nut 4 is screwed onto the second tubular element 5 and can be used to pre-indicate the position of the first tubular element 1.

The dimensions of the first 1 and second plates 8 are selected so as to provide good stability of the adjustable support. In this case, the area of the second plate 8 is larger than the area of the first plate 1.

The length of the first tubular element 1 is at least its diameter. The ratio of the lengths of the first 1 and second 5 tubular elements is selected so that the second tubular element 5 can be screwed into the first tubular element 1 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 first tubular element 1 is equal to the length of the threaded portion of the second tubular element 5.

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 8 with the second tubular element 5 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 8 with the second tubular element 5 rigidly attached to it is installed in a predetermined place of the base (for example, the subfloor) and is attached to the base through the third 22 and / or fourth 24 holes with fasteners (for example, nails, screws, etc. P.). Previously, the nut 4 on the second tubular element 5 is installed in a place to which the first tubular element 2 should be wound onto the second tubular element 5 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 12 of the second tubular element 5 and screwed onto it with the second end 10 having a narrowing 11, thereby forming a joint on the thread of the first inner surface 3 and outer surface 6. Thus, the first tubular element 2 with a first plate 1 and a second tubular element 5 with a second plate 8 form an adjustable support in connection (Fig. 1).

Achieving the required total height of the adjustable support is established by moving the first tubular element 2 along the second tubular element 5 all the way into the nut 4. The orientation of the first plate 1 can be set by turning it so that the location of the first 15 and second 16 holes and cutouts 18 is suitable for mounting and protruding parts of the raised floor parts (plates, beams, etc.), fixed further on the first plate 1. Since the first 15 and second 16 holes are located on the first plate 1 quite often, then adjust irovka orientation of the first plate 1 is practically not affect the overall height of the adjustable feet. After setting the required height of the adjustable support and orientation of the first plate 1, the position of the first tubular element 2 can additionally be fixed from below with a nut 4. Similarly, it can be

any necessary number of adjustable supports is exposed and fixed, and the height of each adjustable support can be set separately.

Implementation of a utility model of an adjustable support with the totality of all the indicated features (the design of the first plate 1 (disk shape, mutual arrangement of the first 15 and second 16 holes, cutouts 18 and the presence of the first 14 and second 20 stiffeners) in combination with the connection of the first a tubular element 2 with a first plate 1; the implementation of the second plate 8 in the form of a square with a depressed central part, the mutual arrangement of the third 22 and fourth 24 holes on it, the third 23 and fourth 28 stiffeners in combination with the connection of the second tubular element 5 with the second plate 8 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 process of adjusting its height. 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.
