Description

Technical Field

[0001] The invention relates to building construction, in particular to a skid-proof construction method for dismantling cantilevered I-beams. Background Art

[0002] With the rapid development of the construction industry, the shape of buildings is becoming more and more complex, especially the requirements for the external frame protection system are getting higher and higher, and the external frame protection system must meet the requirements of strength, rigidity, stability and protection. The conventional practice is to use steel cantilever scaffolding. Most of the practices use No. 16 cantilever I-beams to cantilever the scaffolding. Due to the balcony, the length of the I-beam reaches 6m and 9m. After the scaffolding is dismantled, it is difficult to dismantle the I-beam, and the safety of two-point lifting cannot be guaranteed. Problems and shortcomings of the existing technology: 1. The I-beam is easy to tilt when it is lifted at two points; 2. It is dangerous for personnel to operate on the scaffolding; 3. If it is lifted at one point, the 9m I-beam is easy to fall off, causing safety accidents. Summary of the invention

[0003] The present invention aims to solve the above technical problems, thereby providing a safe and reliable anti-skid construction method for dismantling cantilevered I-beams.

[0004] The present invention solves the technical problem and adopts the following technical solution: A cantilever I-beam removal anti-skid construction method comprises the following steps: S1, pole removal; S2. Install the U-shaped buckle on the I-beam The U-shaped clip includes a U-shaped bolt and a pressure plate, the U-shaped bolt is installed on the cantilever I-beam, and the pressure plate is installed on the U-shaped bolt; S3, Wire rope binding Put one end of the wire rope onto the vertical part of the U-bolt and tighten the nut; S4, draw and hang I-beam Hook the wire rope to the hook of the lifting equipment and lift the I-beam; S5. Place the I-beam on the ground; S6. Remove the U-shaped buckle.

[0005] Compared with the prior art, the present invention using the above technical solution has the following beneficial effects: Prevent the steel wire rope used for binding I-beams in single-point oblique lifting from falling off, increase the stability and safety of I-beams in single-point oblique lifting, and improve construction efficiency; the U-shaped buckle can be reused with low cost.

[0006] Further, the optimization scheme of the present invention is: The U-shaped buckle is fixed on the outside of the I-beam within a range of 500 to 1000 mm from the end.

[0007] The vertical portion of the U-bolt is sleeved with a lifting ring or a shackle.

[0008] A lifting ring is arranged on the pressing plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 is a schematic diagram of a U-shaped buckle according to an embodiment of the present invention; In the figure: U-bolt 1; pressure plate 2; nut 3. DETAILED DESCRIPTION

[0010] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0011] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0012] See also Figure 1 This embodiment provides a method for removing anti-skid construction of cantilevered I-beams, which is carried out in the following steps: S1. Pole removal Remove the uprights of the cantilever scaffolding.

[0013] S2. Install the U-shaped buckle on the I-beam The U-shaped buckle includes a U-shaped bolt 1 and a pressure plate 2. The diameter of the U-shaped bolt 1 is Ф16mm. The pressure plate 2 is a rectangular steel plate with a size of 200X50X5mm. The pressure plate 2 has two round holes that match the vertical part of the U-shaped bolt 1. The U-shaped bolt 1 is installed on the cantilevered I-beam. The U-shaped bolt 1 is fixed on the outside of the I-beam within a range of 500 to 1000mm from the end, and the pressure plate 2 is installed on the U-shaped bolt 1.

[0014] S3, Wire rope binding Put one end of the wire rope onto the vertical part of the U-bolt 1 and tighten the nut 3.

[0015] S4, draw and hang I-beam Hook the wire rope onto the hook of the lifting equipment and lift the I-beam.

[0016] S5. Place the I-beam on the ground; S6. Remove the U-shaped buckle.

[0017] In order to facilitate the installation of the wire rope, the vertical part of the U-bolt 1 can be equipped with a lifting ring or a shackle, and the lifting ring can also be welded on the pressure plate 2. During disassembly, the wire rope is tied to the inner side of the U-bolt 1 to prevent the wire rope tied to the I-beam from falling off, increase the stability and safety of the I-beam when the single-point oblique lifting is lifted, and ensure the safe landing of the I-beam when it is pulled out of the oblique lifting. In addition, the U-bolt 1 can be repeatedly used, which reduces the cost.

[0018] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
