Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and more specifically to an anti-slip rod for I-beams of cantilever scaffolding. Background Technology

[0002] As people's living standards continue to improve, their requirements for building functionality are becoming increasingly complex, and the number of building floors is increasing. During the construction phase of the main structure of a building project, steel pipe scaffolding, also known as protective scaffolding, is erected on the outer perimeter of the main structure. Generally, protective scaffolding below the standard floor uses ground-mounted scaffolding, while protective scaffolding above the standard floor uses cantilevered scaffolding. Cantilevered scaffolding is usually fixed by welding uprights to cantilevered I-beams. This welding method can damage the I-beams, and when the welding deviates, it is very difficult to readjust. This connection method cannot be reused and is wasteful of manpower and resources.

[0003] In existing technologies, steel bars are usually welded to the top surface of the cantilevered I-beam as positioning rods. However, this method can lead to damage or detachment of the welded steel bars during the turnover of the cantilevered I-beam, which can easily cause fatigue damage to the cantilevered I-beam and is also inconvenient to construct.

[0004] Therefore, how to provide a unique, novel, simple, and easy-to-assemble anti-slip bar for cantilevered I-beams is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the present invention provides an anti-slip rod for I-beams of cantilever scaffolding, which aims to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An anti-slip rod for I-beams in cantilever scaffolding includes a bracket, a vertical pole, and bolts;

[0008] The mounting bracket has a slot for engaging with the upper part of the I-beam; the bottom wall of the mounting bracket has multiple threaded holes; the upright is vertically fixed to the top surface of the mounting bracket; the threaded ends of the multiple bolts pass through the multiple threaded holes from bottom to top and abut against the bottom surface of the upper flange of the I-beam to fasten the mounting bracket to the I-beam.

[0009] The beneficial effects of the above technical solution are that, during use, the uprights are fixed to the brackets, and the brackets are fastened to the I-beams with bolts. The support rods of the scaffold can be fitted onto the uprights, which can greatly ensure the anti-slip function of the cantilever scaffold and increase the stability of the scaffold structure. The detachable connection between the brackets and the I-beams facilitates the disassembly and turnover of the brackets and improves resource utilization.

[0010] Preferably, the slot is an inverted U-shaped slot, with the U-shaped opening corresponding to the web of the I-beam, and the slot wall opposite the U-shaped opening abutting against the top surface of the upper flange of the I-beam. The inverted U-shaped slot can be adapted to the upper flange and web of the I-beam, and can be inserted or snapped onto the I-beam. By adjusting the size of the U-shaped slot, the usage requirements of different models of I-beams can be met.

[0011] Preferably, an anti-slip pad is embedded between the groove wall of the slot relative to the U-shaped opening and the top surface of the upper flange plate of the I-beam. The anti-slip pad can increase the friction coefficient between the card holder and the I-beam, and together with the bolts, it can effectively ensure the connection performance between the card holder and the I-beam, ensuring the stability of the cantilever scaffolding support rod after installation.

[0012] Preferably, the bottom of the card holder is provided with multiple threaded holes on both sides of the U-shaped opening of the card slot. The card holder is bolted to both sides of the upper flange of the I-beam relative to the web, improving the connection performance between the card holder and the I-beam.

[0013] Preferably, the upright is a steel bar, with one end vertically welded to the top surface of the card holder. The upright can be made of scrap steel bars welded to the card holder, which is convenient to obtain and has low manufacturing cost.

[0014] Preferably, there are multiple uprights, which are arranged parallel to each other along the length of the bracket. The length of the bracket can be the same as the length of the I-beam. The uprights are arranged according to the erection requirements of the cantilever scaffold, and the support rods of the cantilever scaffold are inserted into the uprights to achieve the erection of the cantilever scaffold.

[0015] Preferably, the outer walls of the multiple uprights are fitted with filler sleeves. In actual construction, the inner diameter of the scaffold support rod and the outer diameter of the upright cannot be perfectly matched. By filling the gap between the scaffold support rod and the upright with filler sleeves, it is ensured that the scaffold support rod will not shake or tilt after being inserted into the upright, thereby improving the safety factor of the cantilever scaffold.

[0016] As can be seen from the above technical solution, compared with the prior art, this utility model discloses a method in which the support rod of the cantilever scaffold can be sleeved on the outer periphery of the upright during use, and the frame of the cantilever scaffold can be tightly connected with the upright, greatly ensuring the anti-slip function of the cantilever scaffold and increasing the stability of the frame; the upright is connected to the I-beam through a bracket, and the fact that the upright is not welded to the I-beam can avoid fatigue damage to the I-beam. At the same time, the bracket and the I-beam are detachably connected, so that the upright will not be damaged during turnover; the slot can meet the use of I-beams of different specifications and models, thus having a wider range of applications.

[0017] This invention is convenient, simple, and easy to operate. It can be used for various types of I-beams, increasing the number of times it can be reused and preventing detachment and damage. It saves costs, shortens the construction period, and ensures the quality of the project. Its simple operation makes it suitable for most people. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model embodiment discloses an anti-slip rod for I-beams of cantilever scaffolding, including a bracket 1, a vertical pole 2, and a bolt 3;

[0025] The card holder 1 has a slot 11 for engaging with the upper part of the I-beam 4; the bottom wall of the card holder 1 has multiple threaded holes; the upright 2 is vertically fixed to the top surface of the card holder 1; the threaded ends of multiple bolts 3 pass through multiple threaded holes from bottom to top and abut against the bottom surface of the upper flange plate of the I-beam 4 to fasten the card holder 1 to the I-beam 4.

[0026] During the erection of cantilever scaffolding, the brackets are inserted into the upper part of the I-beams and secured with bolts. The vertical support rods of the cantilever scaffolding are fitted onto the uprights, allowing the scaffolding structure to be tightly integrated with the uprights, greatly ensuring the anti-slip function of the cantilever scaffolding and increasing the stability of the structure.

[0027] like Figure 2As shown, in this embodiment, the slot 11 is an inverted U-shaped slot. The U-shaped opening of the slot 11 corresponds to the web of the I-beam 4, and the slot wall of the slot 11 relative to the U-shaped opening abuts against the top surface of the upper flange of the I-beam 4. The U-shaped opening of the slot can avoid the web of the I-beam, and the slot can be inserted into the upper part of the I-beam, making installation convenient and quick.

[0028] To further optimize the above technical solution, improve the anti-slip performance between the card holder and the I-beam, and ensure a stable connection between the card holder and the I-beam, an anti-slip pad is embedded between the groove wall of the card slot 11 relative to the U-shaped opening and the top surface of the upper flange plate of the I-beam 4.

[0029] To further optimize the above technical solution, multiple threaded holes are provided on the bottom of both sides of the U-shaped opening of the card holder 1 relative to the card slot 11.

[0030] In some other specific embodiments, the upright 2 is a steel bar, one end of which is vertically welded to the top surface of the mounting base 1. Using scrap steel bars as uprights is convenient in terms of material availability and enables the utilization of waste resources.

[0031] In actual construction, multiple support brackets 1 can be installed, with one upright 2 fixed on each bracket 1. The installation position of the bracket 1 corresponds to the position of the vertical support rod of the cantilever scaffold. Alternatively, the bracket 1 can be arranged along the entire length of the I-beam 4, with multiple uprights 2 arranged parallel to each other along the length of the bracket 1. By connecting multiple uprights with one bracket, the installation foundation of the vertical support rod of the cantilever scaffold is made into a whole, effectively ensuring the anti-slip performance of the cantilever scaffold structure and increasing its stability.

[0032] To further optimize the above technical solution, multiple uprights 2 are fitted with filling sleeves on their outer walls. This ensures a tight connection between the vertical support rods and the uprights of the cantilever scaffold, improving the anti-slip performance and stability of the cantilever scaffold structure.
