DETAILED DESCRIPTION

[0036] The embodiments of the utility model will be further described in detail below with reference to the drawings.

[0037] Embodiment 1

[0038] The precast stair integrated finished product protection device provided by the embodiments of the application comprises a non-slip mat, a fixing part and an extension section, wherein the non-slip mat is laid on the platform beam and the steps of the precast stair, the fixing part is arranged between the non-slip mat and the platform beam and between the non-slip mat and the steps, the extension section comprises a first extension section and a second extension section, the first extension section is arranged at the end of the non-slip mat on the upper platform beam and covers the top of the first gap between the upper platform beam and the upper stair beam, and the second extension section is arranged at the end of the non-slip mat on the lower platform beam and covers the top of the second gap between the lower platform beam and the lower stair beam, thereby achieving the effect of preventing the precast stair from being damaged when the construction personnel pass up and down, and the protection of the fair-faced concrete surface is more remarkable.

[0039] Specifically, the non-slip mat comprises a non-slip mat made of TPE material. The TPE material has good elasticity and wear resistance, which can effectively prevent the construction personnel from slipping when walking. In addition, other materials with good non-slip performance can also be selected, such as PVC, rubber, etc. The thickness of the non-slip mat can be adjusted according to actual needs, generally within the range of 2-5mm, to ensure sufficient non-slip effect and comfort. The fixing part comprises a bolt and a pre-buried sleeve, the pre-buried sleeve can be embedded on the steps, the upper platform beam or the lower platform beam of the precast stair, the bolt is penetrated on the non-slip mat, and the bolt and the pre-buried sleeve are detachably connected. The advantage of this design is that it is convenient to install and disassemble, and at the same time, it is firmly fixed. The material of the pre-buried sleeve can be selected from stainless steel or high-strength carbon steel to ensure its durability and corrosion resistance. The length and diameter of the bolt can be selected according to actual needs, and the commonly used bolt specifications are M8 or M10.

[0040] The extension section includes a first extension section and a second extension section. The first extension section is arranged at the end of the anti-skid pad on the upper platform beam and covers the top of the first gap between the upper platform beam and the upper ladder beam. The second extension section is arranged at the end of the anti-skid pad on the lower platform beam and covers the top of the second gap between the lower platform beam and the lower ladder beam. The material of the first extension section and the second extension section can also be selected from TPE materials, or other materials with good flexibility and durability, such as silicone and TPU. The width of the extension section is generally 10-20 cm to ensure that it can completely cover the gap and prevent dust and debris from entering.

[0041] The implementation principle of the embodiment is to lay anti-skid pads on the platform beams and ladder sections of the prefabricated stairs and fix them with fixing members, and to arrange extension sections at the ends of the anti-skid pads, thereby effectively solving the problem of damage to the prefabricated stairs caused by the passage of construction personnel. In particular, on the exposed concrete surface, this protection device can effectively prevent the construction personnel from slipping when walking, thereby improving the safety of construction. At the same time, since the device is designed to be detachable, it can be easily removed after construction is completed, thereby avoiding the problem of additional waste disposal in traditional methods and reducing construction costs.

[0042] The difference between this embodiment and the above embodiments is that an upturned pad is arranged on both sides of the anti-skid pad. The upturned pad is fixedly connected to the wall on both sides of the prefabricated stairs and covers the top of the third gap between the wall and the prefabricated stairs. This design further enhances the protection effect of the prefabricated stairs, especially for effectively sealing the gap between the wall and the prefabricated stairs to prevent dust and debris from entering.

[0043] Specifically, the upturned pad is also made of TPE material, and its thickness can be slightly smaller than that of the anti-skid pad, generally in the range of 1-3 mm. The height of the upturned pad is generally 10-20 cm to ensure that it can completely cover the gap between the wall and the prefabricated stairs. The fixing member between the upturned pad and the wall includes a bolt and a pre-buried sleeve. The pre-buried sleeve is embedded in the wall, the bolt is embedded in the upturned pad, and the bolt and the pre-buried sleeve are detachably connected. The material of the pre-buried sleeve can be selected from stainless steel or high-strength carbon steel to ensure its durability and corrosion resistance. The length and diameter of the bolt can be selected according to actual needs, and the commonly used bolt specifications are M8 or M10.

[0044] The implementation principle of this embodiment is to further enhance the protection effect of the prefabricated stairs by setting upturned pads on both sides of the anti-skid pad. The upturned pads not only effectively seal the gap between the wall and the prefabricated stairs, preventing dust and debris from entering, but also provide better anti-skid effect when the construction personnel pass up and down. At the same time, due to the use of detachable design, the protection device can be easily removed after the construction is completed, avoiding the problem of additional waste disposal in traditional methods, reducing the construction cost. This design not only improves the safety of construction, but also improves the efficiency and quality of construction. Embodiment 3

[0045] The difference between this embodiment and the above embodiments is that anti-skid strips are arranged on the top surface of the anti-skid pad on the ladder section. The arrangement of anti-skid strips further improves the anti-skid effect of the anti-skid pad, especially in wet and slippery environments, which can effectively prevent the construction personnel from slipping. Specifically, the anti-skid strips can be made of rubber material, and their shape can be convex strips or dots, with a general spacing of 10-20 cm. The height of the anti-skid strips is generally 1-3 mm to ensure that the anti-skid effect is sufficient without affecting the comfort of walking. The anti-skid strips can be fixed on the top surface of the anti-skid pad by adhesive or hot melt process to ensure their firmness and reliability.

[0046] The implementation principle of this embodiment is to further improve the anti-skid effect of the anti-skid pad by arranging anti-skid strips on the top surface of the anti-skid pad on the ladder section. The arrangement of anti-skid strips not only provides good anti-skid effect in dry environments, but also effectively prevents the construction personnel from slipping in wet and slippery environments, improving the safety of construction. At the same time, the installation of anti-skid strips is simple and convenient, and will not affect the overall structure and use effect of the anti-skid pad, which is an economical and practical improvement measure. Embodiment 4

[0047] The difference between this embodiment and the above embodiments is that, in the design of the fixing part, in addition to the bolts and the embedded sleeve, a buckle type fixing part is added. The buckle type fixing part can be quickly installed and disassembled, improving the construction efficiency. Specifically, the buckle type fixing part includes a buckle seat and a buckle head, the buckle seat is fixed on the stair segment, the upper platform beam or the lower platform beam of the prefabricated staircase, and the buckle head is fixed on the non-slip pad. The buckle seat and the buckle head are connected through buckling to ensure the firm fixation of the non-slip pad. The material of the buckle seat and the buckle head can be high-strength nylon or ABS plastic to ensure its durability and anti-aging property. The structural design of the buckle should consider the thickness and softness of the non-slip pad to ensure that the non-slip pad will not be damaged during installation and disassembly. The implementation principle of this embodiment is to further improve the installation and disassembly efficiency of the non-slip pad by introducing the buckle type fixing part. The buckle type fixing part not only installs quickly, but also disassembles conveniently, and will not damage the surface of the prefabricated staircase. This design is particularly suitable for occasions with short construction period and frequent replacement of protective devices, improving the flexibility and efficiency of construction.

[0048] The above description is only a specific embodiment of the present application, which enables those skilled in the art to understand or implement the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to these embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features applied herein.
