Description

Technical Field

[0001] The present disclosure relates to the technical field of steel structure equipment, and in particular to an anchored bending-resistant steel ladder and steel structure equipment. Background Art

[0002] Steel ladders are commonly used in factories and warehouses. In public buildings, they are often used as fire escape stairs. The components of steel ladders are usually connected by bolts, anchors, or welds, and the surface of the components is painted to prevent rust.

[0003] Workers in factories often need to carry heavy objects, so staircases built within factories need to have a strong load-bearing capacity. Generally, the force on steel ladders is concentrated in the middle between the ladder beam and the treads, and the bending moment is greatest there, making it the weakest link in the ladder's load-bearing capacity, thus posing a potential safety hazard.

[0004] Existing technologies such as patent CN209874293U propose a steel structure staircase with an arched support structure, which discloses a left side panel and a right side panel of the stairs arranged in parallel, and a number of concave pedals are arranged at equal intervals from top to bottom between the left side panel and the right side panel of the stairs, and the pedals include a load-bearing plate and fixed plates arranged on the left and right sides of the bottom of the load-bearing plate, and the load-bearing plate and the fixed plate are integrated; reinforcing ribs with arched bottoms are fixed between the fixed plates. Compared with traditional steel stairs, the above-mentioned steel structure staircase can increase the cross-sectional area of ​​the pedals by adding reinforcing ribs at the bottom of the pedals, thereby improving the bending resistance of the above-mentioned pedals and greatly reducing the safety risk of using the above-mentioned steel structure staircase; at the same time, the above-mentioned steel structure staircase is provided with floor positioning holes at the upper and lower ends of the left side panel and the right side panel of the stairs, and chemical anchor bolts are passed through the floor positioning holes and fixed to the main body of the building, so that the above-mentioned steel structure staircase can be fixed to the main body of the building.

[0005] However, when an earthquake occurs or under the action of external loads, the center position of the stair side panels of the above-mentioned steel structure stairs still poses a major safety hazard. Moreover, the above-mentioned steel structure stairs only rely on the friction and chemical bonding between the chemical anchor bolts and the concrete to anchor the stairs to the main body of the building, which makes the anchoring capacity of the above-mentioned steel structure building weak. Moreover, when the building has been used for a long time or is located in an earthquake-prone area, the chemical bonding and friction between the anchor bars and the concrete will gradually be lost, thereby gradually reducing the tensile strength of the above-mentioned steel structure stairs, greatly increasing the safety risk of using the above-mentioned steel structure stairs.

[0038] like Figures 1 to 8 As shown, the anchored bending-resistant steel ladder 10 in one embodiment includes two parallel steel ladder beams 100 and a steel tread 200 provided between the two steel ladder beams 100. The two ends of the steel ladder beams 100 are used to be fixedly connected to the main body of the building. The steel tread 200 is fixedly connected to the steel ladder beams 100. A first reinforcing rib 300 is fixedly connected to the bottom of the steel tread 200. The two ends of the first reinforcing rib 300 are respectively fixedly connected to the two steel ladder beams 100, so that the first reinforcing rib 300 can increase the cross-sectional area of ​​the steel tread 200 and improve the lateral rigidity of the steel tread 200. In addition, the first reinforcing rib 300 can disperse the force to the steel ladder beams 100 on both sides, so that the steel ladder beams 100 can have an inward pulling force when subjected to force, thereby preventing the first reinforcing rib 300 and the steel tread 200 from being easily deformed when subjected to force, thereby strengthening the part of the structure of the steel tread 200 with relatively weak bearing capacity, thereby greatly improving the bending resistance of the steel tread 200.

[0039] like Figures 1 to 8As shown, further, the anchoring anti-bending steel ladder 10 also includes a steel anti-bending component 400 and a steel anchoring component 500. At least one of the steel anti-bending components 400 is arranged between the center positions of the two steel ladder beams 100. The steel anti-bending component 400 is in an X-shaped structure. The two ends of the steel anti-bending component 400 are respectively fixedly connected to the two steel ladder beams 100, so that the steel anti-bending component 400 can increase the cross-sectional area of ​​the steel ladder beam 100 and improve the stiffness of the steel ladder beam 100 along its length direction, so that the part of the structure with weaker bearing capacity of the steel ladder beam 100 is strengthened, thereby greatly improving the anti-bending capacity of the steel ladder beam 100; at the same time, the steel anti-bending component 400 can further improve the anchoring anti-bending steel ladder 10 The lateral rigidity is improved so that when the steel ladder beam 100 is subjected to a large horizontal force, the steel bending-resistant component 400 can restrain the lateral deformation of the steel ladder beam 100, thereby greatly improving the bearing capacity of the anchored bending-resistant steel ladder 10; compared with the existing method of adding reinforcing ribs only at the bottom of the treads of the steel structure stairs, the above-mentioned anchored bending-resistant steel ladder 10 can greatly improve the overall rigidity through the steel bending-resistant component 400 and the first reinforcing rib 300, thereby improving the overall bending resistance of the anchored bending-resistant steel ladder 10, effectively avoiding the phenomenon that the anchored bending-resistant steel ladder 10 is prone to deformation after being subjected to force, and thereby strengthening the part of the structure with weaker bearing capacity of the anchored bending-resistant steel ladder 10, thereby greatly improving the bearing capacity of the anchored bending-resistant steel ladder 10.

[0040] like Figures 1 to 8 As shown, further, the anchoring end of the steel anchoring component 500 is buried in the main body of the building, and the connecting ends of the steel anchoring component 500 are fixedly connected to the two steel ladder beams 100 respectively. The anchoring end of the steel anchoring component 500 is a hook-shaped structure extending outward. The steel anchoring component 500 is used to anchor the steel ladder beam 100 on the main body of the building, so that when the anchored anti-bending steel ladder 10 is subjected to a large tensile force, the steel anchoring component 500 can resist the tensile force through the chemical bonding force and friction force between the steel anchoring component 500 and the concrete 600, thereby improving the anchoring ability of the anchored anti-bending steel ladder 10. At the same time, the steel anchoring component 500 can also be tightly engaged in the concrete 600 through the hook-shaped structure, forming a strong friction resistance and embedding force, thereby further improving the anchoring ability of the anchored anti-bending steel ladder 10, greatly reducing the safety risk of using the anchored anti-bending steel ladder 10.

[0041] In this embodiment, when the center position of the steel pedal 200 is subjected to a large load, the first reinforcing rib 300 will increase the lateral stiffness of the steel pedal 200 and improve the bending resistance of the steel pedal 200, and the first reinforcing rib 300 will also disperse the force to the steel ladder beams 100 on both sides, so that the steel ladder beams 100 can have an inward pulling force when subjected to force, thereby avoiding the first reinforcing rib 300 and the steel pedal 200 from easily deforming when subjected to force. At the same time, the steel anti-bending component 400 can also restrain the lateral deformation of the steel ladder beam 100, further improving the bearing capacity of the steel pedal 200; and when the center position of the steel ladder beam 100 is subjected to a large load, the steel anti-bending component 400 can increase the stiffness of the steel ladder beam 100 along its length direction and improve the bending resistance of the steel ladder beam 100.

[0042] The above-mentioned anchored bending-resistant steel ladder 10 has a first reinforcing rib 300 fixed to the bottom of the steel tread 200, and both ends of the first reinforcing rib 300 are fixedly connected to the two steel ladder beams 100, so that the first reinforcing rib 300 can increase the cross-sectional area of ​​the steel tread 200 and improve the lateral rigidity of the steel tread 200. In addition, the first reinforcing rib 300 will disperse the force to the steel ladder beams 100 on both sides, so that the steel ladder beams 100 can have an inward pulling force when subjected to force, thereby avoiding the first reinforcing rib 300 The phenomenon of deformation is easy to occur when subjected to force, so that the part of the structure of the steel pedal 200 with weaker bearing capacity is strengthened, thereby greatly improving the bending resistance of the steel pedal 200; moreover, at least one steel bending-resistant component 400 is arranged between the center positions of the two steel ladder beams 100, and the steel bending-resistant component 400 is in an X-shaped structure. The two ends of the steel bending-resistant component 400 are respectively fixedly connected to the two steel ladder beams 100, so that the steel bending-resistant component 400 can increase the cross-sectional area of ​​the steel ladder beam 100. The steel ladder beam 100 is strengthened along its longitudinal direction to strengthen the structure of the steel ladder beam 100 with weaker bearing capacity, thereby greatly improving the bending resistance of the steel ladder beam 100; at the same time, the steel bending assembly 400 can further improve the transverse stiffness of the anchored bending steel ladder 10, so that when the steel ladder beam 100 is subjected to a large horizontal force, the steel bending assembly 400 can restrain the transverse deformation of the steel ladder beam 100, thereby greatly improving the bearing capacity of the anchored bending steel ladder 10. Improvement; Compared with the existing method of adding reinforcing ribs only at the bottom of the pedals of the steel structure stairs, the above-mentioned anchored anti-bending steel ladder 10 can greatly improve the overall rigidity through the steel anti-bending component 400 and the first reinforcing rib 300, so that the overall anti-bending ability of the anchored anti-bending steel ladder 10 is improved, and the phenomenon that the anchored anti-bending steel ladder 10 is easily deformed after being subjected to force is effectively avoided, thereby strengthening the part of the structure with weaker bearing capacity of the anchored anti-bending steel ladder 10, thereby greatly improving the bearing capacity of the anchored anti-bending steel ladder 10.

[0043] Since the anchoring end of the steel anchoring assembly 500 is buried in the main body of the building, the connecting ends of the steel anchoring assembly 500 are fixedly connected to the two steel ladder beams 100 respectively, and the anchoring end of the steel anchoring assembly 500 is a hook-shaped structure extending outward. The steel anchoring assembly 500 is used to anchor the steel ladder beam 100 on the main body of the building, so that when the anchored anti-bending steel ladder 10 is subjected to a large tensile force, the steel anchoring assembly 500 can resist the tensile force through the chemical bonding force and friction force between the steel anchoring assembly 500 and the concrete 600, thereby improving the anchoring ability of the anchored anti-bending steel ladder 10. At the same time, the steel anchoring assembly 500 can also be tightly engaged in the concrete 600 through the hook-shaped structure, forming a strong friction resistance and embedding force, thereby further improving the anchoring ability of the anchored anti-bending steel ladder 10, greatly reducing the safety risk of using the anchored anti-bending steel ladder 10.

[0044] like Figures 3 to 5 As shown, in one embodiment, the steel anti-bending component 400 includes a first steel diagonal brace 410 and a second steel diagonal brace 420. The first steel diagonal brace 410 is arranged between the two steel ladder beams 100 along the first direction X, and the second steel diagonal brace 420 is arranged between the two steel ladder beams 100 along the second direction Y. There is an angle between the first direction X and the second direction Y, so that the first steel diagonal brace 410 and the second steel diagonal brace 420 can enhance the overall stiffness of the anchored anti-bending steel ladder 10, so that the first steel diagonal brace 410 and the second steel diagonal brace 420 can constrain the lateral deformation and longitudinal deformation of the anchored anti-bending steel ladder 10, thereby greatly improving the bearing capacity of the anchored anti-bending steel ladder 10.

[0045] like Figures 3 to 5 As shown, in one embodiment, the two ends of the first steel diagonal brace 410 are respectively welded to the two steel ladder beams 100, and the two ends of the second steel diagonal brace 420 are respectively welded to the two steel ladder beams 100. The first steel diagonal brace 410 is fixedly connected to the second steel diagonal brace 420. The first steel diagonal brace 410 and the second steel diagonal brace 420 are both arranged below the steel ladder beam 100 so that the first steel diagonal brace 410 and the second steel diagonal brace 420 can be better fixed on the steel ladder beam 100, avoiding the disconnection between the first steel diagonal brace 410 and the second steel diagonal brace and the steel ladder beam 100 due to the large external load on the anchored anti-bending steel ladder 10, thereby further improving the bearing capacity of the anchored anti-bending steel ladder 10.

[0046] like Figures 3 to 5 As shown, in one embodiment, the included angle is 90° to improve the restraining ability of the first steel diagonal brace 410 and the second steel diagonal brace 420 on the lateral deformation and longitudinal deformation of the anchored bending-resistant steel ladder 10.

[0047] like Figure 1As shown, in one embodiment, there are multiple steel pedals 200, and the multiple steel pedals 200 are spaced apart from top to bottom along the steel ladder beam 100 to reduce walking fatigue, provide safety protection, and adapt to a wider range of building needs.

[0048] like Figure 3 As shown, in one embodiment, each bending-resistant component is arranged at intervals on the steel ladder beam 100, further improving the overall rigidity of the anchored bending-resistant steel ladder 10 and greatly improving the bearing capacity of the anchored bending-resistant steel ladder 10.

[0050] like Figures 7 and 8 As shown, in one embodiment, the steel anchor assembly 500 includes a steel anchor 510 and a steel connector 520. The steel anchor 510 is used to be buried in the concrete 600. One end of the steel connector 520 is welded to the steel anchor 510, and the other end of the steel connector 520 is welded to two steel ladder beams 100, so that the steel ladder beam 100 can be fixed to the steel anchor 510 through the steel connector 520, so that the steel ladder beam 100 can be anchored to the building body through the steel anchor 510.

[0051] like Figures 7 and 8 As shown, in one embodiment, the upper end 511 of the steel anchor 510 is a straight bar structure, and the lower end 512 of the steel anchor 510 is a hook-shaped structure extending outward.

At the same time, the lower end 512 of the steel anchor 510 can also be tightly engaged with the concrete 600 through the hook-shaped structure, forming a strong friction resistance and embedding force, thereby further improving the anchoring ability of the anchored anti-bending steel ladder 10, and greatly reducing the safety risk of using the anchored anti-bending steel ladder 10.

[0052] like Figures 1 to 6As shown, in one embodiment, both ends of the steel pedal 200 and the first reinforcement rib 300 are bolted to the steel ladder beam 100 to facilitate replacement of the steel pedal 200 and the first reinforcement rib 300. The first reinforcement rib 300 is welded to the steel pedal 200 to improve the lateral stiffness of the steel pedal 200.

[0053] like Figure 6 As shown, in one embodiment, the upper surface of the steel pedal 200 is provided with anti-slip grooves 210 to increase the friction coefficient of the surface of the steel pedal 200, thereby reducing the risk of the user falling due to slipping during operation.

[0054] The present disclosure further provides a steel structure equipment, comprising the anchored bending-resistant steel ladder 10 described in any one of the above embodiments.

[0055] Compared with the prior art, the present disclosure has at least the following advantages:

[0056] 1. The above-mentioned anchored bending-resistant steel ladder 10 has a first reinforcing rib 300 fixed to the bottom of the steel step 200. The two ends of the first reinforcing rib 300 are respectively fixedly connected to the two steel ladder beams 100, so that the first reinforcing rib 300 can increase the cross-sectional area of ​​the steel step 200 and improve the lateral rigidity of the steel step 200. In addition, the first reinforcing rib 300 can disperse the force to the steel ladder beams 100 on both sides, so that the steel ladder beams 100 can have an inward pulling force when subjected to force, thereby avoiding the first reinforcing rib 300 from being bent. 00 is prone to deformation when subjected to force, so that the part of the steel pedal 200 with weaker bearing capacity is strengthened, thereby greatly improving the bending resistance of the steel pedal 200; moreover, at least one steel bending-resistant component 400 is arranged between the center positions of the two steel ladder beams 100, and the steel bending-resistant component 400 is in an X-shaped structure. The two ends of the steel bending-resistant component 400 are respectively fixedly connected to the two steel ladder beams 100, so that the steel bending-resistant component 400 can increase the cross-section of the steel ladder beam 100. The steel ladder beam 100 has an area, which improves the rigidity of the steel ladder beam 100 along its length direction, so that the part of the structure with weak bearing capacity of the steel ladder beam 100 is strengthened, thereby greatly improving the bending resistance of the steel ladder beam 100; at the same time, the steel bending assembly 400 can further improve the lateral rigidity of the anchored bending steel ladder 10, so that when the steel ladder beam 100 is subjected to a large horizontal force, the steel bending assembly 400 can restrain the lateral deformation of the steel ladder beam 100, so that the bearing capacity of the anchored bending steel ladder 10 is greatly improved. Improvement; Compared with the existing method of adding reinforcing ribs only at the bottom of the pedals of the steel structure stairs, the above-mentioned anchored anti-bending steel ladder 10 can greatly improve the overall rigidity through the steel anti-bending component 400 and the first reinforcing rib 300, so that the overall anti-bending ability of the anchored anti-bending steel ladder 10 is improved, and the phenomenon that the anchored anti-bending steel ladder 10 is easily deformed after being subjected to force is effectively avoided, thereby strengthening the part of the structure with weaker bearing capacity of the anchored anti-bending steel ladder 10, thereby greatly improving the bearing capacity of the anchored anti-bending steel ladder 10.

[0057] 2. Since the anchoring end of the steel anchor assembly 500 is buried in the main body of the building, the connecting ends of the steel anchor assembly 500 are fixedly connected to the two steel ladder beams 100 respectively, and the anchoring end of the steel anchor assembly 500 is a hook-shaped structure extending outward. The steel anchor assembly 500 is used to anchor the steel ladder beam 100 to the main body of the building, so that when the anchored anti-bending steel ladder 10 is subjected to a large tensile force, the steel anchor assembly 500 can resist the tensile force through the chemical bonding force and friction force between the steel anchor assembly 500 and the concrete 600, thereby improving the anchoring ability of the anchored anti-bending steel ladder 10. At the same time, the steel anchor assembly 500 can also tightly bite into the concrete 600 through the hook-shaped structure, forming a strong friction resistance and embedding force, thereby further improving the anchoring ability of the anchored anti-bending steel ladder 10, greatly reducing the safety risk of using the anchored anti-bending steel ladder 10.

[0058] The above-described embodiments merely represent several implementation methods of the present disclosure. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the scope of the present disclosure, all of which fall within the scope of protection of the present disclosure. Therefore, the scope of protection of the disclosed patent shall be determined by the appended claims.
