Technical Field
[0001] This utility model relates to the field of building construction technology, specifically a protective tool for cantilevered steel beams. Background Technology
[0002] In building construction and high-altitude operations, it is often necessary to fix temporary supports, scaffolding, or protective structures to steel structure beams to facilitate workers' operations or the placement of tools and materials. Steel beam cantilever protective devices, as a common connector, are typically combined with components such as crossbeams, uprights, and steel beams to provide fixed support for construction platforms or protective devices. They are characterized by convenient installation and high detachability, and therefore have been widely used in steel structure construction and safety protection.
[0003] However, some common steel beam cantilever protection tools still have some defects in use. For example, some clamps have a small contact surface with the steel beam, which can easily loosen or deform when the force is concentrated, resulting in insufficient stability. Some clamps lack reliable limiting structures when holding the steel beam. If they are subjected to vibration during construction, the parts may shift or even fall off, posing a safety hazard. Most importantly, existing clamps generally lack flexible adjustment functions, making it difficult to adapt to tools or supports of different specifications, which limits the scope of application and increases construction costs and operational complexity.
[0004] Therefore, there is an urgent need for a steel beam cantilever protection tool that is structurally stable, reliably installed, and highly adaptable, in order to solve the above problems and improve the safety and convenience of the construction process. Utility Model Content
[0005] The purpose of this utility model is to provide a steel beam cantilever protection tool to solve the problems mentioned in the background art, such as the lack of flexible adjustment function of existing clamps, difficulty in adapting to tools or support components of different specifications, resulting in limited application scope, increased construction costs and operational complexity.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a steel beam cantilever protection tool, comprising a protection tool crossbeam, a main beam upright connecting sleeve welded to the left side of the top of the protection tool crossbeam, a protection upright inserted into the main beam upright connecting sleeve, the protection upright and the main beam upright connecting sleeve being fixed by screws, an outer protection tool clamp fixed to the right side of the protection tool crossbeam, an inner protection tool clamp fixedly connected to the right side of the outer protection tool clamp, both the outer and inner protection tool clamps being fixedly connected to the protection tool crossbeam by screws, a steel structure beam embedded between the outer and inner protection tool clamps, a top plate welded to the top of the steel structure beam, two sets of steel sleeves sleeved on the outside of the steel structure beam, each steel sleeve having a steel frame plate welded to its outside.
[0007] As a further technical solution of this utility model, both the steel sleeve and the steel beam of the steel structure are machined with pin holes, and pins are inserted into the pin holes. The steel sleeve and the steel beam of the steel structure are connected by the pins.
[0008] As a further technical solution of this utility model, the inner wall of the steel sleeve is processed with four sets of convex steps, and the outer wall of the steel structure beam is processed with four sets of grooves, and the convex steps and grooves are fitted in size.
[0009] As a further technical solution of this utility model, anti-fall plugs are installed on the outside of the pin holes, and the anti-fall plugs are fixedly connected to the steel sleeve by screws.
[0010] As a further technical solution of this utility model, the steel frame is provided in two sets, and the two sets of steel frame plates are arranged in parallel.
[0011] As a further technical solution of this utility model, the bottom of the steel structure beam matches the size and shape of the outer and inner clamps of the protective tool, and the steel structure beam is in the form of an I-beam.
[0012] As a further technical solution of this utility model, a steel cantilever plate is laid on the top surface of the protective tool beam.
[0013] As a further technical solution of this utility model, protective tool longitudinal beam angle steel is welded to both the left and right sides of the outer wall of the main beam upright connecting sleeve, and the protective tool longitudinal beam angle steel is L-shaped angle steel.
[0014] Compared with the prior art, the beneficial effects of this utility model are: by setting the outer clamp of the protective tool, the inner clamp of the protective tool, and the steel beam of the steel structure, an I-shaped interlocking structure can be formed, making the contact between the clamp and the steel beam tighter, and the force can be evenly distributed when bearing load, reducing the risk of local breakage. In addition, the adjustable design of the steel sleeve and steel frame plate can flexibly adjust the clamping position according to the size of different tools, thus improving the applicability of the clamp. By incorporating protective tool crossbeams, main beam upright connecting sleeves, and protective uprights, a stable support frame can be quickly erected during construction without the need for additional support components, reducing the complexity of the installation process. In addition, the reinforcement effect of the protective tool longitudinal beam angle steel ensures that the uprights remain stable under long-term load conditions, preventing loosening or deformation due to concentrated stress.

[0017] 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.
[0018] Please see Figure 1-6 One embodiment of this utility model provides a steel beam cantilever protection tool, including a protective tool beam 4. A main beam upright connecting sleeve 3 is welded to the left side of the top of the protective tool beam 4. A protective upright 1 is inserted into the main beam upright connecting sleeve 3. The protective upright 1 and the main beam upright connecting sleeve 3 are fixed by screws. A protective tool outer clamp 6 is fixed to the right side of the protective tool beam 4. A protective tool inner clamp 7 is fixedly connected to the right side of the protective tool outer clamp 6. Both the protective tool outer clamp 6 and the protective tool inner clamp 7 are fixed by screws. A steel structure beam 8 is embedded between the outer clamp 6 and the inner clamp 7 of the protective tool and is fixedly connected to the crossbeam 4 of the protective tool. A top plate 11 is welded to the top of the steel structure beam 8. Two sets of steel sleeves 9 are sleeved on the outside of the steel structure beam 8. Steel frame plates 10 are welded to the outside of each steel sleeve 9. Pin holes 14 are machined in the steel sleeves 9 and the steel structure beam 8. Pins 15 are inserted into the pin holes 14. The steel sleeves 9 and the steel structure beam 8 are connected by pins 15. Two sets of steel frame plates 10 are provided and are arranged in parallel. Specifically, such as Figure 1 , Figure 2 and Figure 3As shown, by setting the main beam upright connecting sleeve 3 and the protective upright 1 on the protective tool crossbeam 4, the steel beam cantilever protective tool can quickly form a support frame during installation, avoiding the cumbersome operation that previously required additional support components for fixation. The overall construction is more convenient. The protective tool crossbeam 4 is equipped with an outer protective tool clamp 6 and an inner protective tool clamp 7, which can firmly clamp the steel structure beam 8, improving the fit between the clamp and the steel beam and reducing loosening caused by vibration or force. The steel sleeve 9 on the outer sleeve of the steel structure beam 8 is welded with steel frame plates 10. The distance between the two sets of steel frame plates 10 can be flexibly adjusted to adapt to the fixing requirements of tools of different specifications and reduce the cost of additional custom clamps.
[0019] The inner wall of the steel sleeve 9 is machined with four sets of raised steps 12, and the outer wall of the steel structure beam 8 is machined with four sets of grooves 13. The raised steps 12 and the grooves 13 are fitted in size. Anti-fall plugs 16 are installed on the outside of the pin holes 14. The anti-fall plugs 16 are fixedly connected to the steel sleeve 9 by screws. Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, both the steel beam 8 and the top plate 11 of the steel structure are machined with pin holes 14 and connected by pins 15, so that the steel sleeve 9 can be firmly connected to the steel beam, increasing the overall reliability. At the same time, the inner wall of the steel sleeve 9 is provided with a raised step 12, which fits into the groove 13 on the outer wall of the steel beam, effectively preventing the clamp from rotating under force, thereby maintaining structural stability. In order to further improve safety, an anti-fall plug 16 is installed outside the pin hole 14. The plug is locked with screws, which can prevent the pin 15 from accidentally slipping off during construction vibration and reduce the risk of falling due to loose parts. The steel beam cantilever protection tool not only has reliable load-bearing capacity, but also provides higher safety guarantee in the high-altitude construction environment and reduces the risk of accidents.
[0020] The bottom of the steel structure beam 8 matches the size and shape of the outer clamp 6 and the inner clamp 7 of the protective tool. The steel structure beam 8 is an I-beam structure. The top surface of the protective tool crossbeam 4 is covered with a steel cantilever plate 5. The left and right sides of the outer wall of the main beam upright connecting sleeve 3 are welded with the longitudinal angle steel 2 of the protective tool. The longitudinal angle steel 2 of the protective tool is an L-shaped angle steel. Specifically, such as Figure 1 , Figure 4 , Figure 5 and Figure 6As shown, the outer wall of the main beam upright connecting sleeve 3 is welded with an "L"-shaped protective tool longitudinal beam angle steel 2, which can reinforce the root of the upright under external force, improve the bending and shear resistance of the upright, and ensure that the connection remains stable after long-term load-bearing and is not prone to loosening. The steel structure beam 8, together with the protective tool outer clamp 6 and the protective tool inner clamp 7, form an I-beam interlocking structure, which can evenly distribute the load on the clamp when the steel beam is under force, avoiding the stress concentration and local fracture problems that occur in traditional clamping methods. The top of the protective tool crossbeam 4 is also covered with a steel cantilever plate 5, which can play a role in load bearing and support during construction, not only making it convenient for workers to stand or place tools, but also dispersing concentrated loads.
[0021] Working principle: First, the protective tool beam 4 is fixed to the construction site. The main beam upright connecting sleeve 3 is then tightened to the protective upright 1 with screws, providing foundation support for the subsequent outward projection of the clamp. The protective tool longitudinal beam angle steel 2 on both sides of the main beam upright connecting sleeve 3 strengthens the bending stiffness of the connection point in both the transverse and longitudinal directions, ensuring the upright remains stable under long-term loads and preventing loosening or deformation due to stress concentration. The outer clamp 6 and inner clamp 7 of the protective tool together clamp the steel structure beam 8. The bottom of the steel beam and the clamps form an I-beam interlocking structure, which can distribute concentrated loads to the clamp surface, effectively reducing the risk of localized fracture. The steel sleeve 9 covering the steel structure beam 8 serves as an adjustment component, with two sets of steel frame plates 10 welded to its outer wall. By adjusting the steel sleeve 9... The distance between the steel frame pieces 10 can be flexibly adjusted to change their relative positions, adapting to construction tools of different sizes or thicknesses, thus improving the compatibility and versatility of the device and reducing the cost of clamp replacement due to differences in working conditions. To ensure the stability of the clamp during the stress process, the inner wall of the steel sleeve 9 is machined with a raised step 12, which fits into the groove 13 on the outer wall of the steel structure beam 8, effectively limiting the relative rotation between the two and preventing loosening caused by shaking during high-altitude construction. At the same time, the pin holes 14 on the steel beam and the top plate 11 are fixedly connected by pins 15. The pins 15 are equipped with anti-fall plugs 16 on the outside, which not only further locks the connection between the steel sleeve 9 and the steel beam, but also prevents the pins 15 from slipping due to vibration or construction impact, thus improving the overall safety and reliability.
