[0002] Cast-in-place staircases, as a common building structure, are widely used in various types of buildings due to their excellent structural stability and overall performance. Among them, the assembly of the staircase safety structure has always been a crucial step. In the existing technology of cast-in-place stair construction, there are traditional fixed protective structures, such as metal rod welding or bolt splicing. However, these have assembly problems, making it difficult to match the inclination angle and step height of different staircases. On-site cutting and adjustment are required during installation, which is cumbersome and time-consuming. Moreover, the installation process is highly dependent on tools, which not only increases costs but may also cause safety hazards due to improper operation.
[0003] Furthermore, traditional protective structures are difficult to disassemble and reuse, leading to a waste of resources. Utility Model Content
[0004] The purpose of this utility model is to provide a cast-in-place staircase protective structure that is easy to assemble, in order to solve the problem of inconvenient assembly of the protective structure of cast-in-place staircases in the prior art.
[0005] This utility model is implemented as follows: a cast-in-place staircase protection structure that is easy to assemble includes a cast-in-place staircase body, the staircase body including treads arranged at an angle from bottom to top, the upper end of the treads being provided with a high-end plate and the lower end of the treads being provided with a low-end plate; and longitudinally arranged protective frames are provided on both sides of the staircase body. The protective frame includes longitudinal rods installed on the high-end plate and the low-end plate, as well as multiple inclined rods that are inclined in the same direction as the step section. The inclined rods are arranged on the side of the step section, and the multiple inclined rods are spaced apart along the height direction of the longitudinal rods, with an inclined interval between adjacent inclined rods. The longitudinal rod has a protruding pipe section, and the two ends of the inclined rod have connecting sections respectively. A swing device that can swing and bend to adjust the bending angle is provided between the pipe section and the connecting section. The two ends of the swing device are respectively nested and connected to the pipe section and the connecting section. A bottom gap is formed between the inclined rod and the step section, and the bottom gap is inclined in the same direction as the inclined rod; the bottom gap is covered with a removable bottom baffle, and the bottom baffle is inclined in the same direction as the inclined rod. The upper end of the bottom baffle extends to the high-end plate, and the lower end of the bottom baffle extends to the low-end plate. The two ends of the bottom baffle are connected by longitudinal rods.
[0006] Furthermore, the oscillator includes two opposing oscillating sleeves, each sleeve having a cavity that extends through the outer end of the sleeve to form an open end, and the inner ends of the sleeves being respectively arranged to form closed ends; one sleeve is nested on a pipe segment, the pipe segment being inserted into the cavity through the open end, and the other sleeve is nested on a connecting segment, the connecting segment being inserted into the cavity through the open end; The closed end is provided with a connector, and the closed ends of the two sleeves are arranged facing each other at intervals. The two connectors are hinged to allow the two sleeves to swing relative to each other.
[0007] Furthermore, the inner end of the connector is rotatably connected to the closed end to form a rotating end, and the outer end of the connector forms a hinged end, with the hinged ends of the two connectors hinged together.
[0008] Furthermore, the closed end is provided with a protruding seat, and the rotating end is sleeved on the protruding seat and rotatably connected to the protruding seat, so that the connector head rotates relative to the sleeve.

[0020] Reference Figure 1-6 The image shown is a preferred embodiment of the present invention.
[0021] The easy-to-assemble cast-in-place staircase protection structure includes a cast-in-place staircase body 100, the staircase body 100 including tread sections 101 arranged inclined from bottom to top, the upper end of the tread section 101 is provided with a high-end plate 102, and the lower end of the tread section 101 is provided with a low-end plate 103; the two sides of the staircase body 100 are respectively provided with longitudinally arranged protective frames 200. The protective frame 200 includes longitudinal rods 201 disposed on the high-end plate 102 and the low-end plate 103, and multiple inclined rods 400 inclined in the same direction as the step section 101. The inclined rods 400 are arranged on the side of the step section 101, and the multiple inclined rods 400 are arranged at intervals along the height direction of the longitudinal rods 201, with an inclined interval 401 between adjacent inclined rods 400. The longitudinal rod 201 has a protruding pipe section 202, and the two ends of the inclined rod 400 have connecting sections 203 respectively. A swing device 300 that can swing and bend to adjust the bending angle is provided between the pipe section 202 and the connecting section 203. The two ends of the swing device 300 are respectively nested and connected to the pipe section 202 and the connecting section 203. A bottom gap is formed between the tilting rod 400 and the step section 101. The bottom gap is inclined in the same direction as the tilting rod 400. The bottom gap is covered by a removable bottom baffle 104. The bottom baffle 104 is inclined in the same direction as the tilting rod 400. The upper end of the bottom baffle 104 extends to the upper plate 102, and the lower end of the bottom baffle 104 extends to the lower plate 103. The two ends of the bottom baffle 104 are connected by longitudinal rods 201.
[0022] The above-mentioned easy-to-assemble cast-in-place stair protection structure, through the adjustable function of the swing device 300, combined with the nested connection of the tilt rod 400 and the longitudinal rod 201, enables the tilt rod 400 to adapt to different stair tilt angles without the need for on-site cutting and adjustment, thus simplifying the assembly process and improving assembly convenience. Furthermore, the detachable arrangement of the inclined rods 400 and the bottom baffle 104 not only improves the stability of the protective structure but also reduces the difficulty of positioning, facilitates quick assembly and disassembly, improves construction efficiency, and makes it easy to reuse, thereby reducing resource waste.
[0023] In this embodiment, the oscillator 300 includes two opposing oscillating sleeves 301. Each sleeve 301 has a cavity 302, which extends through the outer end of the sleeve 301 to form an open end. The inner ends of the sleeves 301 are respectively arranged to form closed ends 303. One sleeve 301 is nested on the pipe section 202, and the pipe section 202 is inserted into the cavity 302 through the open end. The other sleeve 301 is nested on the connecting section 203, and the connecting section 203 is inserted into the cavity 302 through the open end. The closed end 303 is provided with a connector 500. The closed ends 303 of the two sleeves 301 are arranged facing each other at intervals. The two connectors 500 are hinged to allow the two sleeves 301 to swing relative to each other.
[0024] This allows the oscillator 300 to flexibly adjust the connection angle between the tilt rod 400 and the longitudinal rod 201 without the need for on-site cutting and adjustment of the pipe section 202 or the connecting section 203. After direct insertion, the angle oscillation is achieved through hinge, which greatly simplifies the installation steps, reduces the dependence on tools, and improves assembly efficiency.
[0025] In actual staircase construction, construction workers can quickly adjust the oscillator 300 according to the actual tilt angle of the staircase to easily complete the assembly of the protective structure.
[0026] In this embodiment, the inner end of the connector 500 is rotatably connected to the closed end 303 to form a rotating end 501, and the outer end of the connector 500 forms a hinge end 502. The hinge ends 502 of the two connectors 500 are hinged together.
[0027] This optimizes the angle adjustment function of the oscillator 300. The rotating connection allows for fine-tuning of the connection angle during installation to match the tilt angle of the stair tread section 101, while the fixed hinge end 502 ensures the stability of the connection. This avoids repeated disassembly and assembly due to angle errors during installation, improving the accuracy and efficiency of assembly. It is especially suitable for scenarios where protective structures require frequent assembly and disassembly.
[0028] In this embodiment, the closed end 303 is provided with a protruding seat 503, and the rotating end 501 is sleeved on the protruding seat 503 and rotatably connected to the protruding seat 503 so that the connector 500 rotates relative to the sleeve 301.
[0029] By setting the boss 503, a stable fulcrum is provided for the rotation of the connector 500, dispersing the stress generated during the rotation process, avoiding excessive wear between the connector 500 and the sleeve 301, extending the service life of the oscillator 300, and at the same time, making the rotation of the connector 500 smoother, improving the reliability of the protective structure during use, and reducing safety hazards caused by loose connections.
[0030] In this embodiment, the hinge end 502 is provided with a plurality of spaced clamping pieces 504, and a clamping groove 505 is formed between adjacent clamping pieces 504. The clamping pieces 504 of the two hinge ends 502 are inserted into each other, and the clamping pieces 504 are movably inserted into the clamping groove 505. The two hinge ends 502 are provided with a hinge shaft 506, which passes through the clamping groove 505 and the clamping pieces 504, and is rotatably connected to the clamping pieces 504 so that the two hinge ends 502 are hinged together.
[0031] By inserting the clamping piece 504 into the clamping groove 505 and rotating the hinge shaft 506, the connection between the two sleeves 301 is both firm and flexible. In this way, construction personnel can quickly insert the clamping piece 504 into the clamping groove 505 and fix it with the hinge shaft 506, realizing the rapid assembly and disassembly of the swing device 300, thereby improving construction efficiency and ensuring the stability of the protective structure during use.
[0032] In this embodiment, the tilting rod 400 is arranged in a break at the middle to form a break interval. The tilting rod 400 has a break section 402 facing the break interval. An adjusting cylinder 403 is provided in the break interval. The adjusting cylinder 403 has an adjusting cavity 404. The adjusting cavity 404 passes through both ends of the adjusting cylinder 403 to form an end opening. The break section 402 is inserted into the adjusting cavity 404 through the end opening and is threadedly connected to the adjusting cylinder 403.
[0033] This disconnectable design, combined with the threaded connection, allows the length of the tilting rod 400 to be flexibly adjusted according to the actual length of the stair tread section 101. In practical applications, construction workers only need to rotate the adjusting cylinder 403 to quickly adjust the length of the tilting rod 400 without cutting or replacing parts, which greatly improves the adaptability and assembly efficiency of the protective structure.
[0034] In this embodiment, the middle part of the adjusting cylinder 403 is provided with an elastic column 405 made of elastic material, which is movably arranged. The broken section 402 is inserted into the adjusting cavity 404 and presses against the end of the elastic column 405 so that the elastic column 405 is in a compressed deformation state.
[0035] In this way, the setting of the elastic column 405 provides a buffer and shock absorption function for the connection of the inclined rod 400. When the staircase is subjected to external impact, the elastic column 405 can absorb some energy, reduce the vibration of the protective structure, and improve the safety of use. In addition, the compression deformation of the elastic column 405 also makes the connection of the inclined rod 400 tighter, preventing the inclined rod 400 from loosening due to external force, and ensuring the stability of the protective structure.
[0036] In this embodiment, a hollow region 406 is provided in the middle of the elastic column 405. The hollow region 406 extends along the axial direction of the elastic column 405 and passes through both ends of the elastic column 405. When the two broken sections 402 press the elastic column 405 towards each other and compress and deform it, the diameter of the hollow region 406 decreases.
[0037] The hollow region 406 optimizes the stress performance of the elastic column 405, so that the stress can be distributed more evenly when the elastic column 405 is compressed, avoiding local stress concentration and improving the fatigue resistance of the elastic column 405. At the same time, the hollow region 406 also reduces the weight of the elastic column 405, making the protective structure lighter and more economical.
[0038] In this embodiment, the elastic column 405 is provided with a plurality of peripheral grooves 407 on its outer periphery. The peripheral grooves 407 extend along the axial direction of the elastic column 405 and pass through both ends of the elastic column 405. The plurality of peripheral grooves 407 are arranged around the elastic column 405 at intervals in the circumferential direction. When the two broken sections 402 press the elastic column 405 towards each other and compress and deform it, the peripheral grooves 407 shrink.
[0039] The outer peripheral groove 407 further optimizes the deformation performance of the elastic column 405, allowing the outer peripheral groove 407 to shrink axially when the elastic column 405 is compressed, increasing the deformation space of the elastic column 405 and improving its buffering effect.
[0040] In this embodiment, the bottom baffle 104 has a longitudinally arranged open cylinder 105 at its end. The open cylinder 105 has a cavity with a side opening 106, which extends longitudinally through both ends of the open cylinder 105. The longitudinal rod 201 is embedded in the cavity through the side opening 106. The open cylinder 105 is nested around the outer periphery of the longitudinal rod 201 so that the bottom baffle 104 is fixedly connected to the longitudinal rod 201.
[0041] This allows the connection between the bottom baffle 104 and the longitudinal rod 201 to be made without additional fasteners or welding. Construction workers can directly insert the longitudinal rod 201 into the clamping cavity to achieve a quick and secure connection. This not only simplifies the installation steps and improves assembly efficiency, but also ensures the firmness of the connection, enabling the bottom baffle 104 to stably cover the bottom gap and enhance the overall integrity of the protective structure.
[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
