Adjustable supporting structure

 

The invention relates to the construction, in particular to an adjustable supporting structure designed primarily for the support at the desired height of the beams of the floor in areas where required to provide access to the underground space. The technical result of the invention is to increase the bearing capacity of the support. Adjustable supporting structure includes a bottom plate, the screw counter nut, one end of which is connected with the upper plate in the form of a disk, is provided on its perimeter crosswise spaced pairs of slots open from the peripheral part of the plate. The free end of the threaded rod installed with the possibility of axial movement in the cavity of the tubular element connected with a rectangular bottom plate. The lower and upper plate has a Central hole to accommodate the subsequent rigid connection with the fins of the ends respectively of the tubular element and the threaded rod and located around the opening of the recess, the depth of which does not exceed the thickness of the plate. The distance between the opposed spaced slots, the longitudinal axes of which lie on the same line, does not exceed 2/3 of the diameter of the disk. 5 Il.

The closest analogue to the invention is adjustable supporting structure including a lower plate, the screw counter nut, one end of which is connected with the upper plate is provided on its perimeter crosswise spaced pairs of slots open from the peripheral part of the plate, and located between adjacent slots, holes, fasteners (EP 0362718, class E 04 F 15/024, 1990).

In the famous decision of the upper plate is made in the form of a flat ring with a pre-installed base gasket overlying the inner diameter of the ring, which leads to additional labor costs in the manufacture of support.

The technical task of the invention is to provide an adjustable support with the top plate having bearing capacity without the installation of additional elements.

This problem is solved due to the fact that the adjustable support structure including a lower plate, the screw counter nut, one end of which is connected with the upper plate is provided on its pyrimido adjacent slots, holes, fasteners, the top plate is made in the form of a disk, the free end of the threaded rod installed with the possibility of axial movement in the cavity of the tubular element connected with a rectangular bottom plate, bottom plate and top plate has a Central hole to accommodate the subsequent rigid connection with the fins of the ends respectively of the tubular element and the threaded rod and located around the opening of the recess, the depth of which does not exceed the thickness of the plate, with the convex surface of the grooves of the upper and lower plates are drawn toward each other, a threaded rod provided with a lock nut that secures the position of the upper plate relative to the bottom, and the distance between the opposed spaced slots, the longitudinal axes of which lie on the same line, does not exceed 2/3 of the diameter of the disk.

In Fig.1 shows a cut adjustable design; Fig.2 is a plan of the bottom plate; Fig.3 - section a-a in Fig.2; Fig.4 is a plan of the upper plate; Fig.5 - section b-b of Fig.4.

Adjustable base plate includes a rectangular bottom, mostly square, plate 1 with the mounting holes 2, the threaded rod 3, which interacts with the adjusting nut 4, and Verhny polozhennymi pairs of slits 6, open with the peripheral part of the disk.

Between adjacent slits at the same distance from the center of the plate at an angle of 45 are holes 7 for fastening elements.

The slots are intended primarily for placement of the side walls of the beams.

Due to the fact that parts of the disk between the slots are the most loaded, the length of the slots should be sufficient to ensure the bearing capacity of the upper plate. In the proposed solution the distance between the slots, the longitudinal axes of which lie on the same line should not exceed 2/3 of the diameter D of the disk.

The free end of the threaded rod 3 is installed with the possibility of axial movement in the cavity of the tubular element 8.

The bottom plate 1 and the top plate 5 has a Central hole 9 for placement of the ends respectively of the tubular element 8 and the threaded rod 3, followed their rigid connection to the plate by welding.

The Central hole 9 in each plate is surrounded by a recess 10, which increases the rigidity of the plate and prevents the vertical load on the most strained her area.

The notch is made by stamping and its depth does not exceed that which meeting each other.

For fixing the position of the upper plate relative to the lower threaded rod provided with a lock nut 11.
