Description

Technical Field

[0001] This utility model relates to the field of protective structure technology, specifically to a protective structure for preventing steel columns from falling off. Background Technology

[0002] The anti-falling steel column crash barrier is a protective device specifically designed for building structural safety, constructed from high-strength alloy steel and a modular structure. Its core function is to create multi-point surface contact between the arc-shaped clamping components and the steel column surface, utilizing an adjustable threaded transmission mechanism to achieve adaptive clamping, thus constructing a dynamic buffer space between the steel column and the protective body. The product innovatively adopts a boltless fixing scheme, converting vertical loads into horizontal frictional forces through mechanical spiral locking technology. This avoids the damage to the ground structure caused by traditional ground anchors while ensuring impact resistance meets the GB / T 3098.1 standard. The crash barrier effectively disperses the kinetic energy impact loads generated by vehicle and equipment collisions. It is widely used in bridge railings, construction sites, and industrial pipe corridors, significantly improving the passive protection level and ease of maintenance of steel structure facilities.

[0003] Chinese patent CN208650394U discloses a protective structure for the base of a steel column. The steel column is installed above a floor slab. The protective structure is characterized by a protective base comprising a protective steel mesh and a formwork assembly around the base of the steel column. The protective steel mesh includes horizontal and vertical reinforcing bars. The horizontal reinforcing bars are clamped to the outside of the steel column base and are arranged along the height of the base. The vertical reinforcing bars are vertically connected to the horizontal reinforcing bars. The formwork assembly includes a first formwork assembly and a second formwork assembly respectively supported on both sides of the protective steel mesh. Concrete is poured between the first and second formwork assemblies, forming the protective structure with the protective steel mesh. This protective structure creates a closed protective barrier around the base of the steel column, preventing corrosion. It is simple in structure and easy to construct.

[0004] The aforementioned protective structure forms a closed protective barrier around the steel column base by pouring a ring of concrete at a certain elevation, preventing corrosion. This structure is simple, easy to construct, and provides good protection for the steel column base. However, while this structure effectively protects the column base and reduces the probability of corrosion, it is relatively simple and lacks an early warning mechanism. When the column base is impacted, there is no warning, and damage often occurs only after the impact has occurred. Therefore, a new protective structure for preventing steel column detachment is proposed. Utility Model Content

[0005] To address the aforementioned issues, a protective structure for preventing steel column detachment is provided. A movable grille drives a push rod to move horizontally, which in turn moves a piston along the central axis of the second chamber. Simultaneously, the piston's movement forces air from inside the second chamber through a mounting base to a pneumatic horn. When air enters the pneumatic horn, it sounds an alarm. This system achieves early warning through the coordinated operation of the movable grille, alarm mechanism, and pneumatic horn, solving the problem of the protective structure's inability to provide early warnings.

[0006] To address the existing technical problems, this application provides a protective structure for anti-falling steel columns, which is applied to anti-falling steel columns. The structure includes a protective frame, a movable grid arranged around the protective frame, an alarm mechanism fixed on the protective frame, a pneumatic horn installed on the alarm mechanism, and a clamping structure set on the top of the protective frame for positioning. Several push rods are horizontally fixed on the side of the movable grid facing the protective frame, and a piston is fixed at the end of the push rod away from the movable grid.

[0007] The alarm mechanism is reported to be fixed on the column inside the protective frame. The inside of the column is provided with a first chamber that can generally be used to install the piston. One end of the column is provided with a mounting seat that can communicate with the first chamber. The pneumatic horn is fixed on the mounting seat.

[0008] As one technical solution of this application, the fixing frame has a threaded rod rotatably provided at its bottom;

[0009] The clamping structure includes a movable frame horizontally arranged at the bottom of the fixed frame, and one end of the movable frame is provided with an arc-shaped clamping plate that can contact the surface of the anti-falling steel column.

[0010] The center of the movable frame is provided with a threaded hole that can be threadedly engaged with the threaded rod, and the threaded hole is fitted onto the threaded rod.

[0011] As a technical solution of this application, a slide rail for limiting the movement of the frame is horizontally fixed on the side of the bottom of the fixed frame near the threaded rod.

[0012] The top of the mobile frame has a groove that allows it to be mounted on and slide along a slide rail.

[0013] As one technical solution of this application, a first chamber is provided inside the column near the second chamber, and a return spring is installed inside the first chamber;

[0014] The push rod is externally fixed with a limiting plate that can contact one end of the reset spring;

[0015] The return spring is mounted on the push rod.

[0016] As one technical solution of this application, the inner arc surface of the arc-shaped clamp is fixed with a protective pad for protecting the surface of the anti-falling steel column.

[0017] As one technical solution of this application, one end of the threaded rod is fixed with a knob that is easy to operate.

[0018] The advantages of this utility model compared to the prior art are:

[0019] 1. This application utilizes a movable grille to drive a push rod horizontally, which in turn moves a piston along the central axis of the second chamber. Simultaneously, the piston's movement delivers air from the second chamber to a pneumatic horn via a mounting base. When air enters the pneumatic horn, it sounds an alarm. This achieves early warning through the coordinated operation of the movable grille, alarm mechanism, and pneumatic horn, solving the problem of the protective structure's inability to provide early warnings.

[0020] 2. This application utilizes a rotating threaded rod, which drives a movable frame through a threaded hole that mates with the rod. This movable frame causes the arc-shaped clamping plate to gradually approach the anti-falling steel column until the arc-shaped clamping plate contacts the surface of the anti-falling steel column. This ensures the clamping structure can be held firmly against the anti-falling steel column, thereby guaranteeing the stability of the protective frame and solving the problem of traditional protective devices requiring bolts to be fixed to the ground.

[0021] 3. This application involves installing a mounting seat inside the first chamber. When the movable grille is compressed, it synchronously drives a push rod, which in turn causes the push rod to compress the mounting seat through a limiting plate. At this time, the mounting seat gradually accumulates elastic potential energy. When the compressive force on the movable grille disappears, the accumulated elastic potential energy of the mounting seat is released. Then, the mounting seat pushes the push rod to move in the opposite direction through the limiting plate, and the push rod's reverse movement simultaneously causes the movable grille to reset.

[0029] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0030] See Figures 1-6 As shown, a protective structure for preventing falling steel columns is applied to the steel columns, including a protective frame 1, a movable grille 5 arranged around the protective frame 1, an alarm mechanism 6 fixed on the protective frame 1, a pneumatic horn 7 installed on the alarm mechanism 6, and a clamping structure 4 set on the top of the protective frame 1 for positioning. Several push rods 51 are horizontally fixed on the side of the movable grille 5 facing the protective frame 1, and a piston 53 is fixed at the end of the push rod 51 away from the movable grille 5.

[0031] The alarm mechanism 6 is fixed to the column 61 inside the protective frame 1. The inside of the column 61 is provided with a first chamber 62 that can generally connect with the piston 53. One end of the column 61 is provided with a mounting seat 64 that can communicate with the first chamber 62. The pneumatic horn 7 is fixed on the mounting seat 64.

[0032] When the movable grille 5 is compressed, it drives the push rod 51 to move horizontally. At this time, the push rod 51 drives the piston 53 to move along the central axis of the second chamber 63. Simultaneously, the piston 53 transports air from inside the second chamber 63 to the pneumatic horn 7 via the mounting base 64. When air enters the pneumatic horn 7, it sounds an alarm. This achieves early warning through the cooperation of the movable grille 5, the alarm mechanism 6, and the pneumatic horn 7, solving the problem of the protective structure's inability to provide early warnings.

[0033] See Figure 3 and Figure 4 As shown, a fixed bracket 31 is provided with a threaded rod 33 rotatably mounted on its bottom;

[0034] The clamping structure 4 includes a movable frame 41 horizontally disposed at the bottom of the fixed frame 31, and one end of the movable frame 41 is provided with an arc-shaped clamping plate 44 that can contact the surface of the anti-falling steel column;

[0035] The center of the movable frame 41 is provided with a threaded hole 43 that can be threadedly engaged with the threaded rod 33, and the threaded hole 43 is fitted onto the threaded rod 33.

[0036] When the threaded rod 33 is rotated, it drives the movable frame 41 through the threaded hole 43, which is in contact with it. This causes the movable frame 41 to move the arc-shaped clamping plate 44 closer and closer to the anti-falling steel column until the arc-shaped clamping plate 44 contacts the surface of the anti-falling steel column. This ensures that the clamping structure 4 can be clamped onto the anti-falling steel column, thereby guaranteeing the stability of the protective frame 1 and solving the problem that traditional protective devices need to be fixed to the ground with bolts.

[0037] See Figure 3 and Figure 4 As shown, a slide rail 32 for limiting the movement of the movable frame 41 is horizontally fixed at the bottom of the fixed frame 31 near the side of the threaded rod 33.

[0038] The top of the movable frame 41 is provided with a slide groove 42 that can be installed on the slide rail 32 and slide with it.

[0039] To ensure the stability of the movable frame 41, a sliding groove 42 is provided on the top of the movable frame 41, and then the sliding groove 42 is installed on the slide rail 32. When the movable frame 41 moves, it slides along the slide rail 32 through the sliding groove 42, effectively preventing the movable frame 41 from deviating during movement. This ensures the stability of the movable frame 41.

[0040] See Figure 6 As shown, a first chamber 62 is provided inside the column 61 near the second chamber 63, and a return spring 65 is installed inside the first chamber 62.

[0041] The push rod 51 is externally fixed with a limiting plate 52 that can contact one end of the return spring 65;

[0042] The return spring 65 is mounted on the push rod 51.

[0043] To enable the movable grille 5 to quickly reset, a mounting base 64 is installed inside the first chamber 62. When the movable grille 5 is compressed, it simultaneously drives the push rod 51, causing the push rod 51 to press against the mounting base 64 through the limiting plate 52. At this time, the mounting base 64 gradually accumulates elastic potential energy. When the compressive force on the movable grille 5 disappears, the elastic potential energy accumulated in the mounting base 64 is released. Then, the mounting base 64 pushes the push rod 51 to move in the opposite direction through the limiting plate 52, and the reverse movement of the push rod 51 simultaneously resets the movable grille 5.

[0044] See Figure 4As shown, the inner arc surface of the arc-shaped clamping plate 44 is fixed with a protective pad 45 for protecting the surface of the anti-falling steel column.

[0045] To prevent damage to the surface of the anti-falling steel column caused by the curved clamping plate 44, a protective pad 45 is fixed to the inner arc surface of the curved clamping plate 44. When the moving frame 41 moves the curved clamping plate 44 close to the anti-falling steel column, it effectively prevents the curved clamping plate 44 from directly contacting the surface of the anti-falling steel column, thereby avoiding damage to the surface of the anti-falling steel column caused by the curved clamping plate 44.

[0046] See Figure 3 As shown, a knob 2 for easy operation is fixed to one end of the threaded rod 33.

[0047] To make rotating the threaded rod 33 easier, a knob 2 is fixed to one end of the threaded rod 33. When the threaded rod 33 needs to be rotated, the user holds the knob 2. Turning the knob 2 causes the threaded rod 33 to rotate. This not only makes rotating the threaded rod 33 easier but also makes operation more convenient.

[0048] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
