Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and particularly relates to an I-beam movable sleeve positioning structure. Background Art

[0002] The most common form of external scaffolding in high-rise buildings is cantilever scaffolding. When erecting cantilever external scaffolding, it is necessary to weld positioning sleeves on the I-beams to secure the uprights to prevent safety hazards caused by shaking or sliding at the base of the external scaffolding uprights. However, this method of securing the uprights with positioning sleeves on cantilever I-beams has the following problems: low efficiency, non-adjustable position, low I-beam reusability, poor turnover, and poor economic benefits. It also suffers from problems such as inaccurate positioning, resulting in poor erection quality of the external scaffolding and large deviations in external dimensions. This results in an unbalanced force system for the entire scaffolding, increasing safety hazards of the external scaffolding.

[0003] Based on this, in order to improve the efficiency of cantilever scaffolding construction and the reuse rate of I-beams, the construction workers used Figure 1 The vertical pole positioner shown includes a positioning clip 17, a positioning sleeve 4, a fixing bolt, a nut, and a splint steel plate 16. The positioning clip 17 first clamps one end of the I-beam 6, and the other end is fixedly connected to the splint steel plate 16 by a bolt. However, when the bolt is tightened, the splint steel plate 16 may rotate with the bolt, resulting in a defect that the position of the splint steel plate 16 and the positioning clip 17 do not correspond, causing the positioner to shake, posing a certain safety hazard. Utility Model Content

[0004] The purpose of the utility model is to overcome the defects in the prior art and provide an I-beam movable sleeve positioning structure.

[0023] In order to make the purpose, technical solution, design method and advantages of the present invention more clear, the present invention is further described in detail below through specific embodiments in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention and are not intended to limit the present invention.

[0024] like Figure 2 As shown, the present invention provides an I-beam movable sleeve positioning structure, comprising a cover plate 2 disposed on the top of the I-beam 6 and a base plate 1 disposed at the bottom of the I-beam 6. The cover plate 2 has two sides that extend outward and bend into a convex-shaped structure. The top width of the convex-shaped structure matches the top width of the I-beam 6, so that when the cover plate 2 is installed, the top of the cover plate 2 is precisely snapped onto the I-beam 6. Connection holes are provided on the horizontal plates in the middle of both sides of the convex-shaped structure. Tension bolts 3 are provided on both sides of the base plate 1. The ends of the tension bolts 3 pass through the connection holes and are connected by nuts. A positioning sleeve 4 is provided at the center of the top of the cover plate 2. During assembly, after the top of the tension bolt 3 passes through the connection hole, the nut is tightened, so that the cover plate 2 and base plate 1 become a single unit and are firmly connected to the I-beam 6.

[0025] like Figure 3As shown, since the connection between the cover plate 2 and the base plate 1 is rigid, there is a risk of the nut loosening due to knocking or other forces after tightening the nut. Therefore, in this embodiment, a hollow plate 7 is further provided at the bottom of the cover plate 2. The inner wall of the hollow plate 7 is provided with a slide groove 8. A sliding plate 9 is provided at the bottom of the cover plate 2, and the sliding plate 9 is slidably connected to the slide groove 8. A base 11 is provided at the bottom of the hollow plate 7. At least two sets of springs 10 are provided inside the hollow plate 7. The top of each spring 10 is connected to the slide plate 9, and the bottom of each spring 10 is connected to the base 11. The sliding plate 9 is integrally formed with the cover plate 2. It should be noted that to ensure the stability of the connection between the cover plate 2 and the base plate 1 and the I-beam 6, after tightening the nut, the bottom of the sliding plate 9 abuts the bottom edge of the slide groove 8. At this time, the spring 10 is in a compressed state. The elastic force of the compressed spring 10 is converted into a reaction force between the cover plate 2 and the tension bolt 3, preventing the bolt from loosening.

[0026] like Figure 4 As shown, positioning grooves 12 are provided on both sides of the base plate 1, and the positions of the positioning grooves 12 are adapted to the base 11. When the tightening bolts 3 pass through the connecting holes, the base 11 is inserted into the positioning grooves 12, further improving the stability of the connection between the cover plate 2 and the base plate 1.

[0027] In the actual construction process, in order to facilitate operation, the diameter of the positioning sleeve 4 is larger than the diameter of the scaffolding pole 18. When the scaffolding pole 18 is inserted into the positioning sleeve 4, there is a risk that the root of the scaffolding pole 18 will shake. In order to solve this problem, Figure 5 As shown, in this embodiment, the positioning sleeve 4 is composed of two symmetrically arranged arc-shaped plates 5. A fixing plate 14 is provided on the outside of the arc-shaped plates 5, and the fixing plate 14 is fixedly connected to the cover plate 2. A threaded hole is provided at the center of the side of the fixing plate 14, and a screw 15 is provided through the threaded hole. The screw 15 is threadedly connected to the threaded hole, and the end of the screw 15 is fixedly connected to the arc-shaped plates 5. A sliding frame 13 is provided on the top of the cover plate 2. The arc-shaped plates 5 are located inside the sliding frame 13 and are slidably connected to the sliding frame 13. In order to ensure that the inner walls of the two arc-shaped plates 5 are in contact with the scaffolding uprights 18, in this embodiment, the central angle of the arc-shaped plates 5 is 120°.

Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
