Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of building construction, and in particular to a multi-level energy-consuming high-altitude falling object interception and buffering device and an early warning method. Background Art
[0002] Fall prevention of high-altitude materials in construction is extremely important. It is a series of measures implemented in construction scenarios to prevent materials from accidentally falling from heights. During the construction process, if materials at high altitudes, such as steel pipes, formwork, tools, etc., fall, it is very likely to cause serious damage to the construction workers, pedestrians and equipment below. Therefore, fall prevention control needs to be implemented from many aspects. First, scientifically plan the material stacking area to ensure that the materials are stacked neatly and firmly away from the edges, and fix the materials that are easy to roll and slide. Second, during the transportation and lifting of materials, strictly follow the standard operation, use qualified lifting equipment and slings, tightly bundle the materials, and control the lifting speed and height. At the same time, set up protective railings, covers or safety nets at the edges and openings of the building to prevent materials from falling from these locations. In addition, safety education and training for construction personnel should be strengthened to improve their safety awareness and operating specifications, jointly ensure the safety of high-altitude materials in construction, and reduce the hazards caused by falling risks.
[0003] Setting up protective structures at the edges and openings of buildings is one of the commonly used anti-falling methods in construction. The protective structure under the existing technology is mainly composed of brackets and anti-falling mesh, which can intercept some falling materials to a certain extent. However, when materials fall and the impact force is large, the materials will pass through the anti-falling mesh and continue to fall, which may cause safety accidents in serious cases. This is because the strength of the anti-falling mesh is limited and it is difficult to withstand a large impact force. This situation fully highlights the problem of poor protective performance of existing protective structures.
[0004] The harm caused by falling materials from high altitudes is huge. It not only threatens the lives of construction workers, but also may cause serious damage to construction projects, affecting the progress and quality of construction. If the problem of poor protection performance of existing protective structures cannot be solved in time, safety hazards in construction will always exist, which may cause major safety accidents at any time, causing irreparable losses to enterprises and society. Therefore, it is necessary to find an effective solution as soon as possible to improve the performance of protective structures and ensure the safety of construction. Summary of the invention

[0035] Example 1
[0036] Please refer to Figure 1 and Figure 2 The embodiment of the present application provides a multi-stage energy-consuming high-altitude falling object interception and buffering device, which is mainly composed of a bearing unit, a first anti-falling screen 1, a second anti-falling screen 5 and a steel cable 9. The bearing unit includes a guide rail 2, a shock-absorbing spring 7 and an I-beam 6. The guide rail 2 is parallel to the I-beam 6 and is arranged at intervals. The shock-absorbing spring 7 is installed between the guide rail 2 and the I-beam 6, and plays a shock-absorbing role between the guide rail 2 and the I-beam 6. The number of bearing units is two, and the two bearing units are parallel and arranged at intervals. The guide rails 2 of the two bearing units are in a first horizontal plane together, and the I-beams 6 of the two bearing units are in a second horizontal plane together, and the first horizontal plane and the second horizontal plane are parallel to each other. The first anti-falling screen 1 is arranged between the two guide rails 2. The second anti-falling screen 5 parallel to the first anti-falling screen 1 is arranged between the two I-beams 6. In addition, a steel cable 9 for supporting the second anti-falling screen 5 is also provided between the two I-beams 6. The steel cable 9 and the first anti-falling screen 1 are respectively located on both sides of the second anti-falling screen 5. There are multiple steel cables 9, which are arranged at intervals along the extension direction of the I-beam 6. Such a structural design can achieve multi-level energy dissipation buffering through the synergistic effect of different components when falling objects occur, effectively intercept falling objects, and reduce the harm caused by falling objects.
[0037] The present application proposes a multi-level energy-consuming high-altitude falling object interception and buffering device, which is mainly used for the exterior of buildings, and its core function is to receive falling objects from buildings. In the actual installation process, it is ensured that the I-beam 6 and the guide rail 2 are firmly connected to the building, and the guide rail 2 is located above the I-beam 6. When a material falls from a high altitude, the falling object will first contact the first anti-falling gauze 1. At this time, through the mutual cooperation of the first anti-falling gauze 1 and the shock-absorbing spring 7, a primary buffering of the falling object can be achieved. If the kinetic energy of the falling object is small, the falling object will be intercepted on the first anti-falling gauze 1, thereby preventing it from continuing to fall and causing harm. However, if the kinetic energy of the falling object is large and passes through the first anti-falling gauze 1, the falling object will continue to fall and contact the second anti-falling gauze 5. In this case, through the coordinated cooperation of the second anti-falling gauze 5 and the steel cable 9, a secondary buffering of the falling object can be achieved, so that the falling object is finally intercepted on the second anti-falling gauze 5. Compared with the traditional single-stage anti-fall structure, the double-stage anti-fall structure proposed in this application has obvious advantages. It greatly increases the interception range and can more effectively deal with falling objects with different kinetic energy. This design greatly reduces the danger of falling objects from high altitudes and provides more reliable safety protection for personnel and equipment under the building. In the actual construction and use process, it has extremely high practicality, can effectively reduce safety accidents caused by falling objects from high altitudes, and provide strong support for safe production in the construction industry.

[0040] In the above embodiment, when the guide rail 2 is installed, its first end is connected to the building, and the second end extends to the outside of the building. When the first anti-falling screen 1 is laid, the connecting rod 4 is driven by the electric wheel 3 to move toward the second direction of the guide rail 2. Since the connecting rod 4 can rotate with the electric wheel 3, the first anti-falling screen 1 wrapped on the connecting rod 4 can be automatically laid between the two guide rails 2. This method effectively replaces the traditional manual laying, greatly reduces the safety risks during the construction process, and significantly improves the safety of the device during construction. When the first anti-falling screen 1 needs to be replaced, the electric wheel 3 is moved toward the first end of the guide rail 2, and the operator removes the old anti-falling screen on the connecting rod 4, and replaces the new anti-falling screen before laying it. Among them, the connecting rod 4 is designed to be cylindrical, so as to better wrap the first anti-falling screen 1.
[0041] In some embodiments of the present invention, the guide rail 2 is provided with a limiting column 8 for limiting the movement of the electric wheel 3 toward the second end of the guide rail 2 .
[0042] In the above embodiment, the design of the limiting column 8 plays a role in limiting the electric wheel 3, which can prevent the electric wheel 3 from sliding too far on the guide rail 2 and slipping off the second end of the guide rail 2. At the same time, the distance R from the limiting column 8 to the first end of the guide rail 2 depends on the height H of the guide rail 2 to the top of the building, specifically: when 2m≤H is less than or equal to 5m, R is 3m; 5m<H≤15m, R is 4m; 15m<H≤30m, R is 5m; when H>30m, R is 6m.
[0043] Specifically, another limiting column 8 is provided at the first end of the guide rail 2 to prevent the electric wheel 3 from slipping on the first end.
[0044] In some embodiments of the present invention, a first connecting bolt is provided at the first end of any of the guide rails 2;
[0045] A first end portion of any of the above-mentioned I-beams 6 is provided with a positioning and mounting piece, and the above-mentioned positioning and mounting piece is provided with a second connecting bolt.
[0046] In the above embodiment, the building structure is provided with a screw hole adapted to the above first connecting bolt, and the first connecting bolt can realize the quick connection or disassembly of the guide rail 2 and the building structure. The building structure is provided with a screw hole adapted to the second connecting bolt, and the cooperation of the second connecting bolt and the positioning mounting plate can realize the quick connection or disassembly of the I-beam 6 and the building structure.
[0047] Preferably, when installing the I-beam 6, it should be ensured that the I-beam 6 is slightly raised upward (toward the top of the building), and it is strictly forbidden for the I-beam 6 to tilt downward.
[0048] In some embodiments of the present invention, there are multiple damping springs 7 , and the multiple damping springs 7 are arranged at intervals along the extension direction of the guide rail 2 .
[0049] In the above embodiment, the design of multiple shock-absorbing springs 7 makes the interception and buffering effect of the present application better.
[0050] In some embodiments of the present invention, the steel cable 9 is detachably mounted on the I-beam 6. When the steel cable 9 is damaged, the steel cable 9 can be easily replaced.
[0051] In some embodiments of the present invention, a processor and a displacement detector that cooperate with each other are also included. The displacement detector is used to monitor the vertical displacement of the outermost end of the second end of the guide rail 2.
[0052] Example 2
[0053] Please refer to Figure 1 and Figure 2The embodiment of the present application provides an early warning method for a high-altitude falling object interception and buffering device with a multi-level energy consumption, comprising the following steps:
[0054] Based on the displacement detector, the vertical displacement ω of the outermost end of the second end of the guide rail 2 is obtained. A ;
[0055] Processor gets dataω A , and the data ω A Compare with its internal preset threshold S;
[0056] If A If it is greater than or equal to S, an alarm will be triggered based on the preset alarm.

This method can monitor the displacement of the guide rail, and once the displacement of the guide rail is too large, an alarm will be issued in time. This makes it easier for staff to maintain and repair the interception and buffer device.
