Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to an easily adjustable cantilevered I-beam positioning mechanism. Background Technology

[0002] Cantilevered I-beams (also called cantilevered steel beams) are I-beams (I-shaped steel beams) that are fixed at one end to the main structure of a building and extend outwards at the other end during construction. Their core purpose is to serve as the main load-bearing beams for cantilevered scaffolding, cantilevered operating platforms, and external scaffolding support, transferring the scaffolding and construction loads to the main structure. A Chinese patent document with publication number CN110905185A discloses a method for fixing a cantilevered I-beam. The method includes the following steps: 1) Pre-embedding a U-shaped steel rod in a concrete slab, the opening of the U-shaped steel rod facing the cantilevered I-beam to be fixed on the concrete slab. Both ends of the U-shaped steel rod form a cylindrical portion with its upper end flush with the upper surface of the concrete slab, and the cylindrical portion has internal threads; 2) A vertical sleeve is detachably connected to the upper surface of the cylindrical portion in step 1), thus isolating the upper surface of the cylindrical portion from the concrete and preventing concrete from condensing. When pouring soil, it enters the interior from the upper end face of the cylindrical part; 3) After step 2) is completed, pour the concrete floor slab. After it is formed, remove the vertical sleeve and screw straight rods into both cylindrical parts. The straight rods are threaded to the cylindrical parts. The upper ends of the two straight rods pass through the first installation holes opened on a metal pressure plate according to the distance between the two straight rods. The metal pressure plate presses against the cantilevered I-beam to be fixed. The upper end of the straight rod is also threaded with a locking nut. The locking nut is located above the metal pressure plate to lock the metal pressure plate and cooperate with the concrete floor slab to fix the cantilevered I-beam, thereby completing the fixing of the cantilevered I-beam; However, the above solution uses a locking nut positioned above the metal pressure plate to lock the metal pressure plate and fix it in conjunction with the concrete floor slab to fix the cantilevered I-beam. However, this method requires pre-reserved connecting parts on the concrete floor slab, making it inconvenient to adjust the installation position of the cantilevered I-beam later, resulting in certain defects in its practical application. Therefore, this invention proposes an adjustable cantilevered I-beam positioning mechanism to solve the above problems. Summary of the Invention

A connecting rod 12 is integrally formed on the primary mounting column 1. The secondary mounting column 2 is symmetrically arranged with the primary mounting column 1, and the secondary mounting column 2 is connected to the connecting rod 12 through a connecting frame 13. A set of connecting rods 12 and connecting frames 13 are symmetrically arranged. The upper positioning plate 3 is located on the upper end of the primary mounting column 1 and the secondary mounting column 2, and the lower positioning plate 4 is located on the lower end of the primary mounting column 1 and the secondary mounting column 2. The mounting plate 5 is located between the upper and lower connecting rods 12, and a threaded hole 21 is opened on the mounting plate 5. The adjusting bolt 6 is installed in the threaded hole 21.

[0019] The cantilevered I-beam 7 has engagement grooves 10 at the top and bottom positions on both sides. The engagement grooves 10 are arranged in four rows at equal intervals at the top and bottom positions on both sides of the cantilevered I-beam 7. The upper side of the upper positioning plate 3 and the lower side of the lower positioning plate 4 are integrally formed with engagement teeth 11. Each cantilevered I-beam 7 is positioned by four cantilevered I-beam positioning mechanisms. A pair of cantilevered I-beam positioning mechanisms are symmetrically arranged on the inner and outer sides of the building wall 8. The engagement teeth 11 are matched with the engagement grooves 10. When the cantilevered I-beam positioning mechanism is in actual use, the engagement teeth 11 are embedded into the engagement grooves 10.

[0020] Guide holes 15 are provided on both the upper positioning plate 3 and the lower positioning plate 4. A set of guide holes 15 is symmetrically arranged on both the upper positioning plate 3 and the lower positioning plate 4. The upper positioning plate 3 and the lower positioning plate 4 are movably installed on the primary mounting column 1 and the secondary mounting column 2 through the guide holes 15. By setting up a cantilevered I-beam positioning mechanism composed of the primary mounting column 1, the secondary mounting column 2, the upper positioning plate 3, the lower positioning plate 4, the mounting plate 5 and the adjusting bolt 6, and by using the four cantilevered I-beam positioning mechanisms to perform multi-angle synchronous positioning of the cantilevered I-beam 7, the positioning stability of the cantilevered I-beam 7 on the building wall 8 is effectively improved.

[0021] Example 2: Based on Example 1, the lower surface of the upper positioning plate 3 is integrally formed with an upper threaded tube 16, and the upper surface of the lower positioning plate 4 is integrally formed with a lower threaded tube 17. The upper threaded tube 16 and the lower threaded tube 17 are coaxially arranged. A positioning component 14 is provided between the upper threaded tube 16 and the lower threaded tube 17. The positioning component 14 includes a screw nut 18, an upper screw 19, and a lower screw 20. The screw nut 18, the upper screw 19, and the lower screw 20 are integrally formed.

[0022] When the positioning component 14 is turned in the forward direction, the upper positioning plate 3 moves to the upper side, and the lower positioning plate 4 moves to the lower side. At this time, both the upper positioning plate 3 and the lower positioning plate 4 are engaged with the cantilevered I-beam 7, and the engaging teeth 11 are embedded in the meshing groove 10. When the positioning component 14 is turned in the reverse direction, the upper positioning plate 3 moves down, and the lower positioning plate 4 moves up.

A primary positioning hole 23 is provided on the side wall of the nut of the adjusting bolt 6. The primary positioning hole 23 is a straight groove. A secondary positioning hole 24 is provided on the side wall of the nut 18 on the positioning component 14. The primary positioning hole 23 and the secondary positioning hole 24 are evenly spaced in a circle. The anti-loosening component 22 includes a sleeve 25, a telescopic rod 26, a support spring 27, a primary positioning post 28, and a secondary positioning post 29. The telescopic rod 26 is movably disposed within the inner cavity of the sleeve 25. The two ends of the support spring 27 are respectively connected to the sleeve... The sleeve 25 and the telescopic rod 26 are connected. The first-level positioning post 28 is integrally formed with the end of the sleeve 25, and the second-level positioning post 29 is integrally formed with the end of the telescopic rod 26. When the support spring 27 is in the reset state, the two ends of the first-level positioning post 28 and the second-level positioning post 29 are respectively inserted into the first-level positioning hole 23 and the second-level positioning hole 24. By setting the anti-loosening component 22, which is composed of the sleeve 25, the telescopic rod 26, the support spring 27, the first-level positioning post 28 and the second-level positioning post 29, a self-locking mechanism is formed on the adjusting bolt 6 and the positioning component 14, thereby improving the application stability of the cantilever I-beam positioning mechanism.
