[0002] In existing technologies, stair edge protection often involves pre-embedding components in the stair treads and then installing the edge protection structure using these pre-embedded components. This method requires simultaneous construction with the staircase's civil engineering pouring, demands high precision in pre-embedded positioning, and makes it difficult to adjust the pre-embedded components later. Furthermore, removal of these components later can easily damage the staircase's concrete structure. This method presents several technical challenges, including the high precision required for installing the protective structure using pre-embedded components, and the risk of damage to the staircase's concrete structure if the pre-embedded components need to be removed later.

[0023] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. In the description of the present invention, it should be understood that terms such as "installation," "connection," and "fixing" should be interpreted broadly, and can refer to direct connection, installation, or fixing, or indirect connection, installation, or fixing. The present invention does not impose any limitations in this regard.

[0024] like Figures 1 to 4 As shown in the schematic diagram, this invention provides an embodiment of a staircase edge protection structure. The staircase treads have a tread surface 11 and an inclined bottom surface 12. The staircase edge protection structure includes a first base plate 4, which is disposed on the tread surface 11; a second base plate 2, which is attached to the bottom surface 12; a connecting rod 3, which is movably connected to the first base plate 4 and rotatably connected to the second base plate 2; and a guardrail, which is connected to the side of the first base plate 4 opposite to the tread surface 11.

[0025] This structure reduces the need for pre-embedded components in the staircase structure; the connecting rod 3 is movably connected to the first base plate 4, which can adapt to stair treads of different thicknesses; the connecting rod 3 is rotatably connected to the second base plate 2, which can deflect, so that the second base plate 2 can adapt to and fit the bottom surface 12 of the staircase with different inclination angles; the staircase edge protection structure is easy to install and dismantle and can be reused.

[0026] Preferably, the first substrate 4 has a reserved hole 5, and the connecting rod 3 passes through the reserved hole 5 and is threadedly connected to the fixing component, which makes the operation convenient, quick and easy and the adjustment accuracy high.

[0027] Preferably, the connecting rod 3 has a threaded section, and the fixing member is a limiting nut 9 disposed on the side of the first base plate 4 away from the tread surface 11, the limiting nut 9 being threadedly engaged with the threaded section. The limiting nut 9 can be used to fasten the first base plate 4 to the tread surface 11.

[0028] Preferably, the guardrail includes uprights 7, which are detachably connected to the first base plate 4 via a locking structure. The detachable connection facilitates modular assembly, disassembly, and transportation.

[0029] Preferably, the locking structure includes a first clamp 6, a second clamp 13, and a locking assembly 8. The first clamp 6 is connected to the first base plate 4, and the second clamp 13 is hinged to the first clamp 6 to clamp the upright 7 and is fixed by the locking assembly 8. In one embodiment, the locking assembly 8 includes a locking bolt connecting the first clamp 6 and the second clamp 13, and a locking nut threadedly connected to the locking bolt. It also includes a reinforcing bolt that can pass sequentially through the side wall of the first clamp 6, the upright 7, and the side wall of the second clamp 13, and a reinforcing nut threadedly connected to the reinforcing bolt.

[0030] Preferably, the guardrail also includes protective rods 10 connecting adjacent uprights 7. The protective rods 10 connect adjacent uprights 7 to form a protective structure, and the protective rods 10 extend parallel to the direction of the stair treads.

[0031] Preferably, the connecting rod 3 is L-shaped, with its vertical section movably connected to the first base plate 4, and its horizontal section passing through the second base plate 2 and connected to the limiting member 1. The connecting rod 3 has a simple structure, and the second base plate 2 can rotate freely around the horizontal section as the axis to adapt to different slopes of the stair bottom surface 12, improving adaptability to stair working conditions with different inclination angles, and is easy to install and dismantle.

[0032] Understandably, in order to improve the stability of the connection, conventional fastening methods can be used for auxiliary reinforcement. For example, some of the first substrate 4 or the second substrate 2 can be anchored to the corresponding surface of the stair tread section through anchors. The specific method will not be elaborated.

[0033] Preferably, the present invention also provides a construction method for a staircase edge protection structure, comprising the following steps:

[0034] The first substrate 4 is attached to the tread surface 11, the relative position of the connecting rod 3 and the first substrate 4 is adjusted and fixed, and during the adjustment process, the second substrate 2 is adaptively deflected relative to the connecting rod 3 to attach to the bottom surface 12.

[0035] The guardrail is connected to the side of the first base plate 4 away from the tread surface 11, forming a stair edge protection.

[0036] Example 1:

[0037] A staircase edge protection structure consists of a first base plate 4, a second base plate 2, a connecting rod 3, and a guardrail.

[0038] Specifically, the stair treads have a horizontally arranged tread surface 11 and a bottom surface 12 that is inclined relative to the horizontal plane. The tread surface 11 is the horizontal step surface that people walk on, and the bottom surface 12 is the inclined bottom surface 12 that is arranged below the treads and opposite to the tread surface 11.

[0039] The first substrate 4 is a flat plate structure, and its lower surface is in close contact with the tread surface 11 of the stair tread section during use. The first substrate 4 has a reserved hole 5, which penetrates the upper and lower surfaces of the first substrate 4 in a direction perpendicular to the surface of the first substrate 4.

[0040] The second substrate 2 is also a flat plate structure, and its upper surface is used to fit against the inclined bottom surface 12 of the stair tread section during use. The second substrate 2 is rotatably connected to the connecting rod 3 to flexibly adjust the orientation of its contact surface, and the second substrate 2 is used to increase the contact area with the bottom surface 12.

[0041] Specifically, the connecting rod 3 is L-shaped, comprising a vertical section and a horizontal section. The outer periphery of the vertical section has external threads for threaded connection with the fixing member (limiting nut 9) after passing through the pre-drilled hole 5 in the first substrate 4. The horizontal section extends horizontally. A shaft hole is formed on the body of the second substrate 2, through which the horizontal section of the connecting rod 3 passes, allowing the second substrate 2 to rotate freely about the horizontal section as its axis. A limiting member 1 is provided at the end of the horizontal section away from the vertical section. This limiting member 1 is a stop fixedly connected to the end of the horizontal section to reduce the risk of the second substrate 2 slipping axially along the horizontal section. The vertical section of the connecting rod 3 is located on the outside of the stair tread section. The second base plate 2 can rotate around the horizontal section of the connecting rod 3 as a pivot, so that its plate surface can adapt to and fit against the bottom surface 12 of the stair tread at different inclination angles. By tightening the limiting nut 9, it is pressed against the first base plate 4. The vertical section of the connecting rod 3 drives the horizontal section to move closer to the first base plate 4, so that the horizontal section of the connecting rod 3 (and the second base plate 2 sleeved on it) and the first base plate 4 respectively abut against the bottom surface 12 and the tread surface 11 of the stair tread section, forming a clamping fixation. The second base plate 2 is used to increase the contact area with the bottom surface 12 and improve stability.

[0042] The vertical and horizontal sections of the connecting rod 3 can be connected by integral bending or welding, with integral bending being preferred to ensure structural strength.

[0043] A first clamp 6 is welded and fixed to the side of the first base plate 4 opposite to the tread surface 11 (i.e., the upper surface). The first clamp 6 is hinged to the second clamp 13 and used to clamp and fix the upright post 7 of the guardrail. The first clamp 6 and the second clamp 13 are both semi-circular arc-shaped plates, which are hinged to each other at one end by a hinge shaft. The end of the second clamp 13 away from the hinge shaft and the corresponding end of the first clamp 6 extend outward to form ear plates, and the two ear plates have corresponding connecting holes. The locking assembly 8 includes a locking bolt and a locking nut. The locking bolt passes through the connecting holes of the two ear plates and is threaded to the locking nut, so that the first clamp 6 and the second clamp 13 can clamp and hold the bottom end of the upright post 7 of the guardrail. Preferably, the locking assembly 8 also includes a reinforcing bolt. The reinforcing bolt passes through the side wall of the first clamp 6, the rod body of the upright post 7, and the side wall of the second clamp 13 in sequence and is threaded to the reinforcing nut, thereby further reinforcing the connection strength between the upright post 7 and the locking structure.

[0044] The guardrail consists of uprights 7 and protective members 10 connecting adjacent uprights 7. The uprights 7 are vertically installed members. The protective members 10 are installed at an angle along the extension direction of the stair treads (i.e., the slope direction), forming a lateral connection with adjacent uprights 7, thus creating continuous edge protection.

[0045] The connection method between the protective rod 10 and the upright 7 is existing technology and can be flexibly designed based on the general technical knowledge of those skilled in the art, such as integral connection or detachable connection by means of bolts.

[0046] In a construction scenario:

[0047] Place the first base plate 4 on the corresponding tread surface 11 of the stair tread section, so that the lower surface of the first base plate 4 is in contact with the tread surface 11. The vertical section of the connecting rod 3 passes through the reserved hole 5 of the first base plate 4. Adjust the relative position of the connecting rod 3 and the first base plate 4. During this adjustment process, the second base plate 2 can adaptively deflect about the horizontal section of the connecting rod 3 as the axis, so that the upper surface of the second base plate 2 is in contact with the corresponding inclined bottom surface 12 of the stair tread section. At this time, tighten the limiting nut 9 that cooperates with the vertical section of the connecting rod 3, so that the limiting nut 9 is pressed against the upper surface of the first base plate 4, locking the relative position of the connecting rod 3 and the first base plate 4, thus completing the upper and lower clamping of the stair tread section. Then, insert the bottom end of the guardrail upright 7 between the first clamp 6 and the second clamp 13, close the second clamp 13, and tighten the locking bolt and locking nut, so that the first clamp 6 and the second clamp 13 clamp the upright 7 tightly. Then, the reinforcing bolts are passed through the first clamp 6, the upright 7, and the second clamp 13 in sequence and tightened with the reinforcing nuts. The protective rods 10 are installed between adjacent uprights 7 to form a staircase edge protection structure.

[0048] This invention can reduce the number of embedded components in the stair treads, reduce damage to the stair structure when the edge protection structure is dismantled, and each component can be reused to adapt to stair treads with different inclination angles or thicknesses, thus improving versatility.

[0049] The embodiments of the present invention have been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made in accordance with the scope of the present invention should still fall within the patent coverage of the present invention.
