RU75408U1 - SET OF ELEMENTS FOR DOUBLE FLOOR FLOORING AND RANGEABLE FOR HEIGHT OF SUPPORT - Google Patents

Abstract

A set of elements and a support for a double flooring, in which the upper support plate (4) of the support is mounted with its central hole (4a) on the tube (3) and fixed to the tube (3), and the tube (3) is connected to the upper support plate by means of deformed sections, while the tube (3) in the initial state can have any size.

Description

The invention relates to a set of elements for a double flooring and a height-adjustable support in which floor plates are supported on the floor base through supports.

A height-adjustable support is known from DE 101 16 313, in which the upper support plate is rigidly connected to the threaded rod by welding. A threaded tube on the lower support plate corresponds in diameter to the threaded rod. In this regard, for installation, the dimensions of the support elements must strictly correspond to each other.

The technical result of the proposed utility model is to simplify and cheapen the design of the support for the double floor.

The technical result is achieved due to the fact that the upper support plate of the support is mounted on the tube due to deformation of the portion of the tube on which the upper support plate is mounted. Thus, the support can be made by using a tube, the manufacture of which does not impose large requirements for tolerances and which in the initial state can have any size.

Forms of the utility model are presented in the following drawings, which depict:

figure 1 is a schematic illustration of a plate with a support;

figure 2 is a longitudinal section of an upper support plate with a tube;

figure 3 is a perspective view of a portion of the tube;

4 is a section of the upper base plate.

1, the letter R denotes the base of the floor on which the support 1 rests, on which, in turn, the plates 2 are supported. The support 1 has a lower support plate 1a adjacent to the base R with a portion 1b provided with a thread on which to adjust the height the tube is screwed onto the support 3, rigidly connected with its upper end to the upper support plate 4.

Figure 2 shows a longitudinal section of a tube 3 connected to the upper support plate 4. The tube 3 is made of a conventional, commercially available tube with low tolerance requirements, which greatly reduces the cost of the design. For fastening the upper support plate 4, the upper end of the tube 3 is thus axially flattened so that outward protrusions 3a are formed at some distance from the upper end of the tube. Then, the upper support plate is mounted on the tube with its central hole 4a (Fig. 4), which fits snugly against the protrusions 3a. Then, using the subsequent flattening process of the upper end of the tube, protrusions 3b are formed, also directed outwards. As a result, the edges of the central hole 4a of the upper support plate are tightly clamped between the two protrusions 3a and 3b. During the second flattening process, the diameter of the upper end of the tube can also be increased in order to align the outer diameter of the tube with the inner diameter

holes 4a of the upper support plate. This allows you to abandon the welding process of the tube and the upper support plate 4 and, accordingly, will provide a cheaper process for manufacturing the support.

The upper base plate has a recess in the central part, so that the edge 4b of the upper base plate in the position shown in FIG. 2 is located above the upper end of the tube and, accordingly, the plate 2 resting on the upper base plate 4 is not in contact with the tube 3 located in deepening the upper support plate 4.

The lower end of the tube, by cold forming, tapers from size D to size d, as a result of which the lower portion of the tube 3c mates with the outer diameter of the threaded rod 1b of the lower support plate 1a.

Figure 3 shows a star-shaped implementation by radially flattening the lower portion 3c of the tube 3 to reduce the diameter in order to mate dimensions. Instead of such a star-shaped embodiment of the end of the tube, any other shaping, for example triangular, polygonal or rectangular, can be made.

It is also possible to expand the portion of the tube with a small diameter by radial deformation in the axial direction so that the outer diameter of the expanded end of the tube corresponds to the diameter of the center hole of the upper support plate to create protrusions for securing the plate from the lower and upper sides of the upper support plate. In the same way, it is thus possible to expand the diameter of the lower portion of the pipe so that the threaded rod will be inserted into the central hole of the lower support plate.

It is preferable for any type of radial deformation, respectively, by cold working the lower end of the tube to simultaneously thread the threads on the inner diameter of the tube, which engages with the threaded rod 1b of the lower support plate 1a.

Figure 4 presents in section the upper support plate 4, made in such a way that it can be used with any floor structure. The number 4a denotes the central hole with which the upper support plate is mounted on the tube.

Thanks to the cold tube forming process, galvanized tubes can be used. Due to the fact that the lower end of the tube 3 is reduced in size, a larger diameter can be provided at the upper end of the tube to better absorb the loads acting on the upper support plate 4.

The form proposed according to the utility model provides a technical result, which simplifies and reduces the cost of the manufacturing process of the support due to the fact that the tube 3 in the initial state of the tube can be of any size, since the dimensions of the tube 3 in the connection area to create a reliable connections to the upper support plate can be changed axially and / or radially.
