Description

Technical Field

[0001] This invention relates to the field of building scaffolding technology, and more specifically, to a gap protection device for building scaffolding. Background Technology

[0002] As a key facility ensuring the safety of high-rise building construction, scaffolding not only provides a working platform for construction workers but also plays a vital role in protection and isolation. Because high-rise building scaffolding must withstand the complex forces of its own weight, construction loads, and wind loads over long periods, it faces high requirements in terms of structural strength, overall stability, and dynamic response. Especially in regions with variable climates, environmental factors such as strong winds, temperature fluctuations, and rain and snow erosion further exacerbate the vibration and deformation risks of the scaffolding system, posing even more significant challenges to its stability and safety.

[0003] Currently, various types of external scaffolding, such as cantilevered and attached types, are used in construction projects. However, in actual construction, a common problem is the excessively large gaps between the scaffolding and the main building structure, with inconsistent gap widths and poor adjustability. These gaps not only easily lead to building materials, tools, and even debris falling from heights, creating safety hazards, but also create harsh working conditions, increasing the difficulty of on-site cleanup and safety management. Furthermore, traditional external scaffolding lacks effective buffering and self-adjusting mechanisms at the connection points with the main structure, making it difficult to cope with scaffolding swaying caused by sudden wind loads or construction loads. This further exacerbates the safety risks in the gap areas, resulting in frequent scaffolding-related safety accidents in high-rise building construction, seriously affecting construction efficiency and personnel safety. Summary of the Invention

[0004] To overcome the shortcomings of the existing technology, the present invention provides a protective device for gaps in building scaffolding. This device...

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0006] A protective device for gaps in building scaffolding is disclosed. This device is installed between the building scaffolding and the main structure, and includes a collection groove, a gathering device, a buffer assembly, a screening assembly, and a bearing saddle. The collection groove is located on the building scaffolding, with two grooves symmetrically arranged as a group. The gathering device is installed within the collection groove. Several buffer assemblies are provided, and each buffer assembly connects the collection groove to the main structure. The bearing saddle is located on the main structure, and the collection groove can slide left and right along the bearing saddle. The screening assembly is installed between two groups of collection grooves. When objects fall from the gaps in the scaffolding during construction, the collection groove and gathering device gather the scattered objects into the screening assembly for sorting and collection according to particle size. When the scaffolding is subjected to external force and shakes, the buffer assembly achieves a gradual transition between rigidity and flexibility in the connection structure, absorbs the swaying amplitude, and adjusts the width of the gaps in the scaffolding.

[0007] The collection trench includes an L-shaped receiving groove, an arc-shaped end, and a steel guard plate. The steel guard plate is hinged to the L-shaped receiving groove and is used to protect the device from impacts by falling objects.

[0008] The collection device includes a guide groove, an I-beam guide rail, a sliding contact line groove, a sliding contact line, a first drive motor, a traction wheel, double-headed fastening studs, a C-shaped fixing frame, a lever, and a rubber mat. The guide groove is arranged along the length of the collection trench. The I-beam guide rail is arranged on the guide groove. The C-shaped fixing frame is detachably mounted on the I-beam guide rail via double-headed fastening studs. The first drive motor is fixed to the C-shaped fixing frame. The traction wheel is assembled at the output end of the first drive motor, and the traction wheel rolls with the I-beam guide rail to achieve collection along the I-beam. The guide rail moves along the H-shaped guide rail; the sliding contact line groove is installed on one side of the guide rail, the sliding contact line is set in the sliding contact line groove and connected to the lever, and the sliding contact line is electrically connected to the first drive motor; one end of the lever is connected to the C-shaped fixing frame, and the other end is connected to the rubber mat, one end of the rubber mat is linked with the lever, and the other end is fixed to the L-shaped receiving groove; when the first drive motor drives the traction wheel to move along the H-shaped guide rail, the C-shaped fixing frame drives the lever to move synchronously, and the lever moves the rubber mat to undulate towards the screening component, realizing the collection of scattered objects.

[0009] The buffer assembly includes thin steel sheets, thick steel blocks, steel strands, push rod heads, push rod frames, steel wire bundles, threaded push rods, a first base, a shell tube, a second drive motor, and a second base. The shell tube is mounted on the main structure via the second base. Several thin steel sheets and thick steel blocks are spaced apart. The thick steel block near the L-shaped receiving groove is fixed to the L-shaped receiving groove. The steel strands pass through and connect each thin steel sheet and thick steel block before being connected to the push rod head. The steel strands, thin steel sheets, thick steel blocks, and steel strands form a buffer structure that can dissipate and absorb the energy generated by the shaking of the outer frame by swinging left and right. The threaded push rod is threaded inside the shell tube. Both ends of the threaded push rod are connected to the push rod frame and the second drive motor, respectively. The push rod frame is fixedly connected to the push rod head. The steel wire bundle passes through each thin steel sheet before being fixedly connected to the push rod frame. The first base fixes the shell tube to a thin steel sheet near the shell tube. The second drive motor is slidably mounted on the main structure and moves synchronously in the horizontal direction with the threaded push rod.

[0010] The screening component includes a conical distribution disc, a transmission disc, transmission teeth, a third drive motor, and a sorting cylinder. The conical distribution disc is located on the upper part of the sorting cylinder. The conical distribution disc has several through holes of different widths arranged in a ring at different heights. The through holes are connected to the bottom sorting cylinder. The transmission disc is arranged around the outer wall of the conical distribution disc. The third drive motor drives the conical distribution disc to rotate through the transmission teeth and the transmission disc.

[0011] The sorting cylinder contains several silos with through holes of different widths corresponding to the conical distribution plate.

[0012] The bearing saddle includes a saddle and a roller. The roller is mounted on the saddle. The collection groove contacts and engages with the roller through an L-shaped receiving groove. Pushing the L-shaped receiving groove allows it to slide left and right along the roller, achieving precise positioning of the collection groove.

[0013] The steel guard plate has a hinged structure that allows for rotation. When impacted by a falling object, the steel guard plate can rotate around the hinge point with the L-shaped receiving groove and generate buffer deformation, further enhancing the protection effect on the device body.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] This system enables the automatic capture, transport, and sorting of objects falling from heights. It changes the traditional reliance on manual cleanup, instantly eliminating safety hazards caused by falling objects. A unique buffer device composed of thin steel sheets, thick steel blocks, and steel strands effectively dissipates the swaying energy of the scaffolding caused by wind and impacts, acting as a "shock absorber." More importantly, it can gradually transform the connection structure from flexible to rigid through a drive motor and steel wire bundles, actively "locking" in extreme conditions such as strong winds to enhance overall stability. Simultaneously, the device can dynamically adjust the gap between the scaffolding and the main structure, adapting to ascent or settlement during construction, ensuring the continuous effectiveness of the protection system and structural safety. Through the cooperation of conical distribution discs with through-holes of different sizes and sorting silos, the system can automatically sort collected falling objects according to particle size. This not only avoids the mixed accumulation of construction waste but also facilitates the subsequent recycling of building materials. The collection device uses I-beam guide rails and sliding contact lines for power supply, ensuring smooth operation and sustained power, avoiding the problem of easy wear and tear on drag chain cables, and ensuring the continuity and reliability of the collection operation. The rubber mats and roller design of the bearing saddles used in the collection device embody the design concept of low wear and high durability, reducing long-term maintenance costs.

Detailed Implementation

[0030] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0031] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0032] like Figures 1 to 13 As shown, a protective device for gaps in building scaffolding is installed between the building scaffolding 1 and the main structure 7. The device includes a collection groove 2, a gathering device 3, a buffer assembly 4, a screening assembly 5, and a bearing saddle 6. The collection groove 2 is installed on the building scaffolding 1, with two grooves symmetrically arranged as a group to collect various debris or building materials falling from the gaps in the scaffolding. The gathering device 3 is installed within the collection groove 2 to orderly push the scattered materials to the screening area. Several buffer assemblies 4 are arranged at intervals along the length of the scaffolding, and these buffer assemblies connect the collection groove 2 and the main structure 7, serving both a force transmission function and an adjustment and buffering function. The bearing saddle 6 is set on the main structure 7, and the collection groove 2 can slide left and right along the bearing saddle 6 to realize the relative displacement adaptation between the outer frame and the main structure; the screening component 5 is installed between the two sets of collection grooves 2 to classify the collected materials; when objects fall from the gaps in the outer frame during construction, the scattered objects are gathered into the screening component 5 and classified by particle size through the collection groove 2 and the gathering device 3, realizing the automatic recycling and classification of fallen objects and avoiding secondary cleaning; when the outer frame 1 is shaken by external force, the buffer component 4 realizes the gradual transformation of the rigidity and flexibility of the connection structure, consumes the swing amplitude and adjusts the gap width of the outer frame 1, ensuring construction safety and structural stability.

[0033] Preferably, the collection trench 2 includes an L-shaped receiving groove 21, an arc-shaped end 22, and a steel guard plate 23. The steel guard plate 23 is hinged to the L-shaped receiving groove 21. The steel guard plate 23 is used to protect the device from impact by falling objects. The arc-shaped end 22 is used to prevent interference with adjacent devices when the end of the collection trench 2 sinks.

[0034] Preferably, the collection device 3 includes a guide groove 31, an I-beam guide rail 32, a sliding contact line groove 33, a sliding contact line 331, a first drive motor 34, a traction wheel 341, a double-headed fastening stud 35, a C-shaped fixing frame 36, a lever 37, and a rubber mat 38. The guide groove 31 is arranged along the length of the collection trench 2, providing an installation and guiding foundation for the entire collection mechanism. The I-beam guide rail 32 is set on the guide groove 31 and has high bending and torsional resistance. The C-shaped fixing frame 36 is detachably installed on the I-beam guide rail 32 by the double-headed fastening stud 35, which facilitates adjustment of the installation position and maintenance. The first drive motor 34 is fixed on the C-shaped fixing frame 36, and the traction wheel 341 is assembled at the output end of the first drive motor 34. The traction wheel 341 and the I-beam guide rail 32 roll together to achieve movement along the I-beam guide rail 32. It has the advantages of stable operation and low noise; the sliding contact line groove 33 is installed on one side of the guide groove 31, the sliding contact line 331 is set in the sliding contact line groove 33 and connected to the lever 37, and the sliding contact line 331 is electrically connected to the first drive motor 34 to realize mobile power supply and avoid the problem of easy wear of drag chain cables; one end of the lever 37 is connected to the C-shaped fixing frame 36, and the other end is connected to the rubber mat 38. One end of the rubber mat 38 is linked with the lever 37, and the other end is fixed to the L-shaped receiving groove 21; when the first drive motor 34 drives the traction wheel 341 to walk along the I-shaped guide rail 32, the C-shaped fixing frame 36 drives the lever 37 to move synchronously, and the lever 37 pushes the rubber mat 38 to rise and fall in the direction of the screening component 5 to realize the gathering of scattered objects. Its rising and falling action can effectively push light debris and blocky materials, adapting to various falling object situations.

[0035] Preferably, the buffer assembly 4 includes thin steel sheets 41, thick steel blocks 42, steel strands 421, push rod head 43, push rod frame 44, steel wire bundle 441, threaded push rod 45, first base 46, shell tube 47, second drive motor 48, and second base 49; the shell tube 47 is mounted on the main structure 7 via the second base 49, serving as the support and outer shell for the entire buffer and adjustment mechanism; several thin steel sheets 41 and thick steel blocks 42 are spaced apart to form a layered buffer structure similar to a "multi-layer spring sheet," with the thick steel block 42 near the L-shaped receiving groove 21 fixed to the L-shaped receiving groove 21; the steel strand 421 passes through and connects each thin steel sheet 41 and thick steel block 42 before connecting to the push rod head 43. The steel block 42 and the steel strand 421 form a buffer structure, which can dissipate and absorb the energy generated by the shaking of the outer frame 1 by swinging left and right. Its multi-layer design can adapt to vibrations of different amplitudes and has good energy dissipation capacity. The threaded push rod 45 is threadedly connected inside the shell tube 47. The two ends of the threaded push rod 45 are respectively connected to the push rod frame 44 and the second drive motor 48. The push rod frame 44 is fixedly connected to the push rod head 43. The steel wire bundle 441 passes through each thin steel sheet 41 and is fixedly connected to the push rod frame 44. The first base 46 fixes the shell tube 47 to a thin steel sheet 41 near the shell tube 47. The second drive motor 48 is slidably set on the main structure 7 and moves synchronously with the threaded push rod 45 in the horizontal direction to achieve fine adjustment of the overall position.

[0036] When the swing amplitude of the outer frame 1 exceeds the preset range or the movement of the outer frame 1 needs to be restricted, the second drive motor 48 starts and drives the threaded push rod 45 to rotate, thereby tightening the steel wire bundle 441 to restrict the swing of the thin steel sheet 41, realizing the gradual transformation of the connection of the buffer component 4 from flexible to rigid. This function is particularly suitable for strong wind weather or sudden impact conditions, and can quickly improve the overall rigidity and prevent the outer frame from shaking excessively.

[0037] When the gap between the outer frame 1 and the main structure 7 exceeds the preset range, the gap between the outer frame 1 and the main structure 7 is adjusted by starting the second drive motor 48 to ensure that the protective device is always in an effective working position and can adapt to the possible climbing or settling of the outer frame during construction.

[0038] Preferably, the screening component 5 includes a conical distribution disc 51, a transmission disc 52, transmission teeth 53, a third drive motor 54, and a sorting cylinder 55. The conical distribution disc 51 is disposed on the upper part of the sorting cylinder 55, and its conical surface structure is conducive to the uniform dispersion of materials. The conical distribution disc 51 is provided with several through holes of different widths at different heights, and the through holes are connected to the bottom sorting cylinder 55, which can realize the graded discharge of materials according to particle size. The transmission disc 52 is disposed around the outer wall of the conical distribution disc 51. The third drive motor 54 drives the conical distribution disc 51 to rotate through the transmission teeth 53 and the transmission disc 52, so that the materials pass through the through holes of different heights in sequence according to particle size under the centrifugal action, realizing continuous automated sorting.

[0039] Preferably, the sorting cylinder 55 is provided with several silos of different widths corresponding to the through holes of the conical distribution plate 51. Each silo is independently separated, which facilitates classified collection and subsequent transportation. For example, a large stone silo or a debris silo can be set up to improve the efficiency of waste management.

[0040] Preferably, the bearing saddle 6 includes a saddle 61 and a roller 62. The roller 62 is mounted on the saddle 61. The collecting groove 2 contacts and engages with the roller 62 through an L-shaped receiving groove 21. Pushing the L-shaped receiving groove 21 allows it to slide left and right along the roller 62, achieving precise positioning of the collecting groove 2. The roller 62 is made of wear-resistant alloy steel, with a smooth surface and high load-bearing capacity, ensuring that the collecting groove 2 can slide smoothly when the outer frame shifts, avoiding jamming or excessive frictional resistance.

[0041] Preferably, the hinge structure of the steel guard plate 23 is a rotatable connection. When impacted by a falling object, the steel guard plate 23 can rotate around the hinge point with the L-shaped receiving groove 21 and generate buffer deformation, further enhancing the protective effect on the device body. This hinge structure design has a certain rotational damping, which can automatically reset after impact, ensuring the continued effectiveness of protection.

[0042] The above description only illustrates the preferred embodiments of the present invention. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention, and all such changes should be included within the protection scope of the present invention.
