Abstract

The utility model relates to a fixing mechanism for a mechanical parking column in a basement. A structure part D (7) is welded on the column (2) top, and its upper plane has a certain distance from the top of the basement, and some threaded holes (8) are processed on the structure part D (7). The expansion bolt of fixed column bottom plate is changed into inner forced expansion nut (12). During installation, bolt A (11) passes through the column base plate (4) from top to bottom and is fixed with the internal expansion nut (12) embedded in the ground. Screw the bolt B (9) through the threaded hole (8) and the free state nut (10) on the structural part D (7) from bottom to top, and tighten it with the basement, and then turn the free state nut (10) downward tight. After the installation is completed, the column "stands upright" and is very firm. The utility model does not need to punch holes on the roof of the basement, and is simple and reliable. Moreover, components such as beams and diagonal stays are omitted. The vertical and horizontal space occupied on the ground of the parking space reaches the minimum, which is a very cost-effective method and has high value.

Description

A fixing mechanism for a mechanical parking column in a basement

Technical field

The invention relates to a fixing mechanism for a mechanical parking column in a basement.

Background technique

At present, the fixing method of the mechanical parking column in the basement is generally to fix the column base plate and the rear base plate on the basement floor with expansion bolts, the diagonal tie rods connect the column top and the rear base plate, and the left and right columns are fixed by cross beams. Because the expansion bolts that fix the rear floor bear a large upward pulling force, if the concrete quality of the basement floor is poor, the expansion bolts will sometimes be pulled out, causing major accidents. And the back floor must have a larger distance from the column, so it needs to take up a larger space in the longitudinal direction of the parking space ground. Although the general technicians know that it is the best way to fix the top of the column and the roof of the basement, but it is not allowed to drill holes to install expansion bolts on the roof of the basement, so there are no embedded parts on the roof of the basement. Under such circumstances, it is basically impossible to fix the top of the column and the roof of the basement at present.

The purpose of the present invention is to provide a technical solution for fixing the top of the column to the roof of the basement without drilling holes on the roof of the basement without any damage to the roof of the basement, so that the fixing of the column is simple and reliable.

Contents of the invention

The present invention is realized in this way: a structural part D is welded on the top of the column, and its upper plane has a certain distance from the top of the basement, and several threaded holes are processed on the structural part D. The expansion bolts that fix the bottom plate of the column are changed to internal forced expansion nuts. When the column is installed, the bolt A passes through the column bottom plate from top to bottom and is fixed with the inner expansion nut embedded in the ground. The bolt B is screwed through the threaded hole and the free state nut on the structural part D from bottom to top, and is tightened with the top of the basement. Then tighten the free state nut downward. The free state nut not only shares the stress on the threaded hole on the structural part D, but also prevents the bolt B from loosening. After the installation is completed, the column "stands upright" and is very firm. In order to prevent the column from loosening due to the shrinkage of the steel when the temperature drops, the bolt B can be tightened up again when the weather cools down for the first time after installation. When the temperature rises, the steel expands, and the stress is absorbed by a small amount of bending in the steel itself. This fixing mechanism does not need to drill holes on the roof of the basement, and the upward stress of the bolt B and the original downward stress of the basement roof are offset to complement each other.

The present invention is very simple, but effect is very reliable. Moreover, components such as beams and diagonal stays are omitted. The vertical and horizontal space occupied on the ground of the parking space reaches the minimum, which is a very cost-effective method and has high value.

Figure 6 is a perspective view of an embodiment of the present invention.

With reference to accompanying drawing 1: column base plate (4) and rear base plate (6) are all fixed on the ground with expansion bolt (5). One end of the diagonal tie rod (3) is connected to the top of the column (2), and the other end is connected to the rear base plate (6). The tops of the left and right columns are fixed by the beam (1).

With reference to accompanying drawing 2,3: structural part D (7) can be made with profiles such as flat steel, I-beam, channel steel or rectangular pipe. Accompanying drawing 2, what 3 shows is to make with flat steel. Structural part D (7) is welded on the top of column (2), and some threaded holes (8) are processed above, and its quantity specification can be adjusted according to the requirements of different products and the height of the basement. When installing the column, first drill a hole at the corresponding position on the ground, embed the internal expansion nut (12), then place the column at the corresponding position, pass the bolt A (11) through the bottom plate of the column (4) from top to bottom and insert it into the ground The lower internal expansion nut (12) is fixed. Screw the bolt B (9) through the threaded hole (8) and the free state nut (10) on the structural member D (7) from bottom to top, and tighten it with the basement, and finally turn the free state nut (10) downward tight.

With reference to accompanying drawing 3,4: What accompanying drawing 3,4 show is the scheme that structural part D (7) is made of I-beam and rectangular tube, and the quantity of bolt B (9) is 8 in accompanying drawing 3 scheme, accompanying drawing 4 out of 4 schemes.

detailed description

Below in conjunction with embodiment the present invention is described in further detail.

With reference to accompanying drawing 6: column (2) is made of I-beam. Structural member D (7) is made of flat steel. 6 bolts B (9) are used for each column, and they are tightened with the top of the basement (13). Each bolt B (9) is equipped with a free state nut (10). The left and right columns (2) are not connected to each other by other components. (14) is a cantilever, and (15) is a power unit oil cylinder, and (16) is a vehicle-carrying plate, all of which are common techniques. No more details here.

In this embodiment, the column (2) is made of 180 I-beam, the structural part D (7) is made of 150*12 flat steel, and the specification of the bolt B (9) is M20*70.
