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 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.

The closest technical solution is an adjustable support (RF patent No. 2278227, priority March 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 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 tubular element 2 and the second plate 11 in rigid connection with the threaded rod 8, and these parts are movably connected to each other, i.e. the threaded rod 8 is screwed into the tubular element 2 (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 19, third 12, first 18 and second 25 central holes) of the first 1 and second 11 plates with their bend with the formation on one side of the protruding parts and the corresponding recessed parts on the opposite side. The material from 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 11 there is a round first central hole 18 (hereinafter referred to as round, we 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 2 or threaded rod 8).

The central part 3 of the first plate 1 is located around the first Central hole 18, made indented towards the tubular element 2.

In this case, the diameter of the first plate 1 is 88 mm, its thickness is 3 mm; the diameter of the first central hole 18 is 20 mm, the diameter of the central part 3 is 38 mm, the depression depth of the central part 3 is 4 mm.

On the first outer edge 16 of the first plate 1, on the perimeter side, eight cutouts 17 are identical in shape and size. The cutouts 17 are open from the first outer edge 16, are arranged radially, and each two nearby cutouts 17 are at an equal angular distance from each other . Each cutout 17 is bounded by two straight parts 20 and an arched between them

part 21, directed by its convexity to the center of the first plate 1. Straight parts 20 are located at an angle to each other so that they converge towards the center of the first plate 1. Each cutout 17 has a plan in shape, symmetrical with respect to the radius of the first plate 1, held through the axis of the arcuate part 21 of the cutout 17 (in this case, we mean the axis of the circle, part (arc) of which is the section of the arcuate part 21).

Between the cutouts 17 are arranged alternately through one of the first 5 and second 19 holes; all in all, on the first plate 1 there are four similarly arranged first holes 5 at the same distance from the first outer edge 16 and four similarly arranged second holes 19 at the same distance from the first outer edge 16.

In this case, all the first holes 5 are made round and have the same diameter (8 mm). All second holes 19 are also made round and have the same diameter (7 mm), smaller than the diameter of the first holes 5.

The first holes 5 are located closer to the first outer edge 16 than the second holes 19. The axes of the aforementioned first 5 and second 16 holes are parallel to the axis of the first central hole 18.

The tubular element 2 has the form of a segment of a pipe of circular cross section (figure 1). A thread is made on the inner surface 6 of the first tubular element 2, and its diameter is equal to the thread diameter of the threaded rod 8. The tubular element 2 is made with a narrowing 14 in the direction of the second plate 11 (i.e. with a smaller outer diameter than the rest of the tubular element 2) . The thread is made on the inner surface 6 of the tubular element 2 at the site of narrowing 14, starts from the second end 9 of the tubular element 2 and ends at the transition of the narrowing 14 to the rest of the tubular element 2. The tubular element 2 is passed through its first end 4 into the first central hole 18, orthogonally attached (in this case, by welding, Fig. 1 shows a weld 15) to the first plate 1 in its central part 3 so that its axis coincides with the axis of the first central hole 18, from the side where the central convex is directed Part 3 of the first plate 1.

In this case, the length of the tubular element 2 is 53 mm, its outer diameter is 19 mm, the length of the narrowing 14 is 20 mm, the outer diameter of the narrowing 14 is 18 mm.

Additionally, on the inner surface 6 of the tubular element 2 there may be longitudinal protrusions (in this case, there is one longitudinal protrusion,

figures not shown). This longitudinal protrusion can be formed, for example, due to the manufacture of the tubular element 2 from a welded pipe.

The threaded rod 8 is inserted with its first end 13 into the second central hole 25, is rigidly orthogonally attached to the second plate 11 in its center so that its axis is orthogonal to the second plate 11 (Fig. 1). In this case, the threaded rod 8 is attached to the second plate 11 with the subsequent expansion of its first end 13 in the form of a hemisphere from the side of the second plate 11, opposite to where the bulges of the stiffeners 23 are located. The length of the threaded rod 8 is 63 mm, diameter 15 mm.

A nut 10 is screwed onto the threaded rod 8 with the possibility of moving along the thread along its entire length, from the second end 7 of the threaded rod 8 to the stop in the second plate 11.

The second plate 11 is made in the form of a disk with a second outer edge 22 and has a constant thickness (4, 5). In this case, the diameter of the second plate 11 is 95 mm, its thickness is 2 mm.

In the second plate 11 there is a second central hole 25. In this case, the second central hole 25 is round, its diameter is 13 mm.

On the second plate 11, around the second central hole 25, there is a first annular protrusion 27 directed by its convexity towards the threaded rod 8. In a section orthogonal to the surface of the second plate 11, the surface of the first annular protrusion 27 facing the threaded rod 8 has the shape of a half circle. The height of the first annular protrusion 27 in this case is 6 mm.

The first annular protrusion is surrounded by an annular recess 26, which has an annular shape in the orthogonal axis of the second central opening 25 of the cross section. The bottom 29 of the annular recess 26 is in the form of a flat ring, and the plane of the bottom 29 is also orthogonal to the axis of the second central hole 25.

Around the annular recess 26, in the direction from it to the second outer edge 22, there is a second annular protrusion 28, directed by its convexity towards the threaded rod 8. In the cross section orthogonal to the surface of the second plate 11, the second annular protrusion 28 has a half-ring shape (except for sections , from which the stiffeners 23). The height of the second annular protrusion 28 in this case is 7 mm.

The second outer edge 22, the second annular protrusion 28, the annular recess 26, the first annular protrusion 27 are concentrically toward the center of the second plate 11.

Eight stiffening ribs 23, identical in shape and size, are made on the second plate 11. The stiffening ribs 23 are in the form of elongated protrusions with rounded ends 24. The stiffening ribs 23 are radially arranged, and the angular distance between any two adjacent stiffening ribs 23 is the same. The ribs 23 extend from the second annular protrusion 28 in the direction of the second outer edge 22, end from it at a distance of approximately equal to 4 mm They are directed by their bulges towards the threaded rod 8. In this case, between the stiffeners 23, the second annular protrusion 28 and the surface of the second plate 11 facing the threaded rod 8, there are clear transition boundaries (Fig. 4), in other cases, these transitions can be made smooth.

In this case, the depth of the first stiffening ribs 23 from the side opposite to the tubular element 2 is 4 mm, and their length (measured from the point of transition of the second annular protrusion 28 into the stiffening ribs 23 to the farthest point of the rounded end 24) is 15 mm.

In the second plate 11 there are eight round third holes 12 located at the same distance from its center, between the second annular protrusion 28 and the second outer edge 22. Each of the third holes 12 is located between two adjacent stiffening ribs 23, at an equal angular distance from them. In this case, the third holes 12 have the same diameter of 12 mm. The axis of the third holes 12 and the second central hole 25 are parallel to the axis of the threaded rod 8.

The stiffening ribs 23, the annular recess 26, the first 27 and the second 28 annular protrusions are made so that their convex parts are on one side of the second plate 11 facing the threaded rod 8, and on the opposite side of the second plate 11 there are corresponding recesses, this the thickness of the second plate 11 is unchanged (figure 5). The surface portions of the second plate 11 from the side opposite the threaded rod 8, located in the region of the annular recess 26, the third holes 12 and the second outer edge 22 are located in the same plane.

To facilitate the perception of the drawings in figure 1, the welded connection of the first plate 1 with the tubular element 2, as well as the connection of the second plate 11 with

the threaded rod 8 is shown conditionally, in FIGS. 2-5, a part of the identical designations is not affixed.

Device operation

illustrating a special case of the 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 a threaded rod 8 rigidly attached to it is installed in a predetermined place of the base (for example, the subfloor) and is attached to it through the third holes 12 with fasteners (for example, nails, 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 2 and the threaded rod 8 are selected so that the first tubular element 2 can be screwed onto the threaded rod 8 taking into account the size of the height adjustment range of the adjustable support.

Previously, the nut 10 on the threaded rod 8 is installed in a place to which the tubular element 2 should be wound on it to provide the necessary height of the adjustable support.

The tubular element 2 with the first plate 1 is brought up from above to the second end 7 of the threaded rod 8 and screwed onto it with its second end 9 until it stops in the nut 10, thereby forming a connection on the thread. Thus, the tubular element 2 with the first plate 1 and the threaded rod 8 with the second plate 11 form an adjustable support in connection (Fig. 1).

The achievement of the required total height of the adjustable support is established by twisting / screwing the tubular element 2 onto the threaded rod 8. Moreover, the orientation of the first plate 1 can be set by turning it so that the location of the first 5 and / or second 19 holes and cutouts 17 is suitable for fasteners and protruding parts, respectively 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 position

the tubular element 2 can additionally be fixed on the bottom with a nut 10. Similarly, any necessary number of adjustable supports can be fixed and fixed, the height of each adjustable support can be set separately. Guide profiles are inserted into the cutouts 17 of the first plate 1 and secured to it through the first 5 and / or second 19 holes. 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 5 and second 19 holes, cutouts 17 and the execution of the Central part 3 of the first plate 1 curved contributes to the optimal distribution of the load on the first plate 1 and the preservation of the constant shape and size of the first plate 1.

The execution of the second plate 11 in the form of a disk with stiffening ribs 23 made extending from the second annular protrusion 28, contributes to the uniform distribution of loads on the second plate 11, increases its rigidity and reliability of attachment to the floor. The location in the same plane of the surface areas of the second plate 11 from the side opposite the threaded rod 8, in the region of the annular recess 26, the third holes 12 and the second outer edge 22 contributes to better stability of the adjustable support, while increasing the uniformity of load transfer from the adjustable support to the base on which it is fixed.

Implementation of a utility model of an adjustable support with a combination of all these features (the design of the first plate 1 in the form of a disk with a first central hole 18, the relative position of the first 5 and second 19 holes, cutouts 17 of the specified shape, the presence of a convex central part 3, the design of the second plate 11 in the form a disk with a second Central hole 25, with the first 27 and second 28 annular protrusions and an annular recess 26 between them, with the third holes 12, with stiffeners 23) in combination with the specified way connected 2 cm of the tubular member 1 to the first plate; with the connection of the threaded rod 8 with the second plate 11 made in this manner, the presence of a nut 10, 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.
