DETAILED DESCRIPTION

[0021] In order to further understand the content, features and functions of the utility model, the following embodiments are given, together with the attached Figures 1 to 3 The detailed instructions are as follows.

[0022] like Figures 1-2 As shown, this embodiment provides an equipment foundation embedded part with adjustable height, which is fixedly arranged between the anchor plate 1 and the foundation bottom surface 2. The equipment foundation embedded part includes a plurality of first anchor bar assemblies 3 and second anchor bar assemblies 4 arranged at intervals, wherein a steel bar sleeve 41 is arranged in the middle of the second anchor bar assembly 4, and the steel bar sleeve 41 adjusts the height of the anchor plate 1 by adjusting the length of the second anchor bar assembly 4. The above-mentioned second anchor bar assembly 4 also includes a horizontal steel bar 42 arranged on the upper surface of the foundation bottom surface 2.

[0023] The utility model can adjust the height of the top surface of the anchor plate at will by arranging anchor bars with adjustable height under the embedded steel plate, and the adjustment margin can be up to about 50mm; in addition, by arranging horizontal steel bars on the bottom surface of the foundation, a good supporting effect is played on the entire embedded part, and all the concrete is poured in one layer, and the layered pouring and the installation of transition channel steel or I-beam for leveling are eliminated, and the embedded part setting and concrete pouring are completed at one time according to the normal construction sequence, which can greatly improve the construction efficiency; and the elimination of the original transition channel steel or I-beam for leveling and the auxiliary steel structure for fixing the embedded parts can save a lot of steel.

[0024] In this embodiment, the length of the horizontal steel bar 42 is 150-200 cm. It is supported on the foundation and the bottom surface of the floor slab, and finally embedded in the concrete foundation. Finally, the first anchor bar assembly 3 and the second anchor bar assembly 4 bear the load of the entire equipment foundation embedded parts together.

[0025] In this embodiment, Figure 2 and 3 As shown, the second anchor bar assembly 4 also includes a first vertical steel bar 43 and a second vertical steel bar 44 located at the upper end of the horizontal steel bar 42. The upper end of the first vertical steel bar 43 is fixedly arranged on the lower surface of the anchor plate 1. The first vertical steel bar 43 and the second vertical steel bar 44 are connected by a steel bar sleeve 41. The ends of the first vertical steel bar 43 and the second vertical steel bar 44 are respectively provided with a first threaded portion 431 and a second threaded portion 441 that cooperate with the inner thread of the steel bar sleeve 41. The surface threads of the first threaded portion 431 and the second threaded portion 441 are arranged in reverse. The length of the inner thread of the steel bar sleeve 41 determines the adjustable height range of the upper anchor plate. In this embodiment, its length is 50 mm, but other values ​​between 40 and 60 mm can also be used.

[0026] The utility model provides a steel bar sleeve, and respectively provides a first threaded portion and a second threaded portion that cooperate with the inner thread of the steel bar sleeve at the ends of the first vertical steel bar and the second vertical steel bar. Thus, when the steel bar sleeve is tightened at the same time, the height of the upper anchor plate can be adjusted by adjusting the length of the first vertical steel bar, thereby meeting the embedding accuracy requirements of the embedded parts and ultimately ensuring the stability of the top surface of the anchor plate.

[0027] In this embodiment, the second vertical steel bar 44 and the horizontal steel bar 42 are integrally formed by a bending process, which facilitates processing and manufacturing.

[0028] In this embodiment, the first anchor bar assembly 3 includes a plurality of short steel bars 31 arranged around a single second anchor bar assembly 4, and the lower ends of the short steel bars 31 do not contact the upper surface of the foundation bottom surface 2. The number and diameter of the short steel bars 31 are determined according to calculations, and are used to bear the pull-out and shear resistance of the embedded parts, and the number of the short steel bars 31 is generally not less than 4.

[0029] In this embodiment, when the diameters of the first vertical steel bars 43 and the short steel bars 31 are large, holes can be drilled on the anchor plate 1 first, and then the first vertical steel bars 43 and the short steel bars 31 are passed through and then fixed by plug welding; when the diameters of the first vertical steel bars 43 and the short steel bars 31 are small, they can be directly welded to the bottom surface of the anchor plate 1.

[0030] In this embodiment, the diameters of the first vertical steel bar 43, the second vertical steel bar 44 and the horizontal steel bar 42 are the same, and the inner diameter of the steel bar sleeve 41 matches the diameter of the first vertical steel bar 43 or the second vertical steel bar 44. This facilitates manufacturing and also facilitates the processing and manufacturing of the inner thread of the steel bar sleeve 41.

[0031] In this embodiment, the upper surface of the anchor plate 1 is flush with the top surface of the concrete or 2-3 mm higher than the top surface of the concrete, so as to prevent the concrete from covering the top surface of the anchor plate, which is not conducive to on-site welding.

[0032] The utility model described above only expresses the implementation method of the utility model embodiment, and cannot be understood as limiting the scope of the utility model patent, nor is it any form of limitation on the structure of the utility model embodiment. It should be pointed out that for ordinary technicians in this field, several changes and improvements can be made without departing from the concept of the utility model embodiment, which all belong to the protection scope of the utility model embodiment.
