Description

Technical Field

[0001] This utility model relates to the field of steel structure staircase technology, specifically to an insertable steel structure staircase with a front-mounted safety kick. Background Technology

[0002] Steel staircases are staircases made of various general-purpose steel profiles, adapted to the main structure, and connected at various component joints by bolts, anchors, welding, or other methods.

[0003] During normal main construction, due to the special sawtooth structure of the staircase, ordinary skirting boards cannot guarantee the complete enclosure of the staircase side protection. The gaps at the bottom of the steel pipes and safety nets built on the side of the staircase can easily cause small materials such as screws and nuts to fall off, which can easily lead to safety accidents and cause injury to construction workers on the floors below.

[0004] As disclosed in Chinese Patent CN217175864U, a splicing stair tread kickboard is designed by pulling the first and second plates to adjust them to a suitable width. Then, a butterfly knob is rotated, causing a locking screw to rotate. This rotation of the locking screw moves a locking tooth block, engaging it with the locking groove to secure the first and second plates. A splicing pin is then inserted into the splicing hole to join multiple kickboards together. Simultaneously, the position of the connecting seat is adjusted, and a connecting sleeve is fixed to the steel pipe using fixing bolts and nuts. The butterfly nut is then rotated for further fixation. This design facilitates the connection and fixation of steel pipes of different heights and inclinations, thereby concealing small materials such as screws and nuts and improving safety.

[0005] However, in existing steel structure staircases, the height between the treads is about 15cm. When it rains, the stair treads become slippery. If workers are performing equipment maintenance, their calves may slip between the treads, causing them to lose their balance and fall. According to safety management personnel, the above-mentioned accidents are more likely to occur when the stair treads are icy in winter.

[0006] Therefore, we urgently need to provide an insertable steel structure staircase with a front-mounted safety kick. Utility Model Content

When it rains, the stair treads become slippery. If workers are performing equipment maintenance, their calves may accidentally slip between the stair treads, causing them to lose their balance and fall. According to the assessment of safety management personnel, the stair treads are more likely to freeze in winter, which makes the above-mentioned accidents more likely to occur.

The outer surface of the slider is slidably connected to the inner wall of the convex groove in the middle of the guide block, the damping rod is a spring-loaded damping rod, and the outer surface of the anti-slip plate has an anti-slip groove.

[0013] Preferably, the supporting connection structure includes a top platform, a handrail connected to the top surface of the top platform, a diagonal rod fixedly connected to one end of the front bottom of the top platform, and a support frame connected to the back of the diagonal rod.

[0014] Preferably, the bottom surface of the top platform is fixedly connected to the top of the support leg, the bottom end of the handrail is connected to the top of the diagonal bar, one end of the back of the support frame is fixedly connected to the outer surface of the support leg, and the two diagonal bars are fixedly connected to the left and right ends of the step on one side close to each other.

[0026] Please see Figure 1 - Figure 5 This utility model provides a technical solution: an insertable steel structure staircase with a front safety kick, including a support leg 1. A support connection structure is installed on the top and front of the support leg 1. A protective structure is installed in the middle of the support connection structure, and a fixing structure is installed at the bottom of the protective structure. The protective structure includes an insertable anti-slip unit and a protective unit, with the protective unit installed on the front of the insertable anti-slip unit. The insertable anti-slip unit includes a step 201. Limiting blocks 202 are installed at both ends of the front of the step 201. An insert plate 203 is connected to the outer surface of the limiting block 202, and an anti-slip plate 204 is connected to the top of the insert plate 203. The protective unit includes a guide block 205. A slider 206 is connected inside the guide block 205. A protective plate 208 is installed at one end of the front of the slider 206, and a damping rod 207 is installed on one side of the back of the protective plate 208 near the center.

[0027] The bottom surface of the anti-slip plate 204 abuts against the top surface of the step 201, the back of the insert plate 203 is slidably connected to the front of the step 201, the guide block 205 is fixedly installed on the left and right ends of the front of the insert plate 203, and one end of the back of the damping rod 207 is fixedly connected to the front of the insert plate 203.

[0028] The supporting connection structure includes a top platform 101, with a handrail 102 connected to the top surface of the top platform 101. A diagonal rod 103 is fixedly connected to one end of the bottom front of the top platform 101, and a support frame 104 is connected to the back of the diagonal rod 103. The bottom surface of the top platform 101 is fixedly connected to the top of the support leg 1, the bottom end of the handrail 102 is connected to the top of the diagonal rod 103, one end of the back of the support frame 104 is fixedly connected to the outer surface of the support leg 1, and the two diagonal rods 103 are fixedly connected to the left and right ends of the step 201 on one side close to each other.

[0029] The fixing structure includes a fixing block 301, a fixing bolt 302 installed in the middle of the fixing block 301, and a fixing nut 303 connected to one end of the front surface of the fixing bolt 302. The top of the fixing block 301 is fixedly connected to the middle of the bottom surface of the step 201, the outer surface of the fixing bolt 302 is threadedly connected to the inner wall of the threaded through hole in the middle of the fixing block 301, and the fixing nut 303 is fixedly installed inside the mounting groove in the middle of the back of the insert plate 203.

[0030] The protective structure, through the insertion of the insert plate 203 and the limiting block 202, and the contact between the anti-slip plate 204 and the top surface of the step 201, effectively blocks the gaps between the steps and prevents icing, thus achieving an anti-slip effect. The installation of the protective unit, utilizing the protective plate 208, the damping rod 207 for cushioning and shock absorption, and the guide sliding of the slider 206 in the middle of the guide block 205, effectively provides protection, preventing workers from kicking the insert plate 203 and causing injury to the front of their feet.

[0031] Working principle:

[0032] When installing the kick plate, the insert plate 203 is inserted between two L-shaped limiting blocks 202 to complete the insertion of the insert plate 203. This allows the bottom surface of the anti-slip plate 204 to abut against the top surface of the step 201, effectively utilizing the anti-slip grooves on the top surface of the insert plate 203 to achieve an anti-slip effect. It is also convenient to use the anti-slip grooves to wrap hemp rope or burlap sacks, thus achieving an anti-slip effect. In case of rain, the center of the anti-slip groove is slightly higher than the ends to guide the rainwater, effectively preventing water accumulation and freezing. Since the installation of the insert plate 203 can cover the gap between two adjacent steps 201, it effectively prevents workers' feet from sliding into the gap between two adjacent steps 201 and causing injury. Furthermore, since the protective plate 208 is installed on the front of the insert plate 203, when workers climb the stairs and kick the protective plate 208 with excessively large steps, the pressure of the protective plate 208 on the damping rod 207 effectively buffers and reduces the impact force. Simultaneously, during the displacement of the protective plate 208 under impact, the sliding block 206 within the guide block 205 ensures the stability of the protective plate 208 during displacement, thus effectively dispersing the impact force to the four damping rods 207. After inserting the insert plate 203, the fixing bolt 302 is rotated to secure the insert plate 203 with the fixing block 301 and fixing nut 303, ensuring the stability of the insert plate 203 after installation and thus guaranteeing the safety of the kick plate during installation and use.
