[0001] This application relates to the technical field of construction anti-falling, and more specifically, to a safety anti-falling device for building construction. Background Art
[0002] Building construction refers to the production activities in the implementation stage of engineering construction, which is the construction process of various buildings. It can also be said to be the process of turning the various lines on the design drawings into physical objects at the designated location. It includes foundation engineering construction, main structure construction, roofing engineering construction, decoration engineering construction, etc.
[0003] When constructing the building roof, such as waterproofing, repairing the building roof, and installing photovoltaic panels for photovoltaic power generation or installing wind power generation components, etc., all belong to high-altitude operations. In order to protect the lives of construction workers, it is generally required that construction workers wear safety belts. When reaching the roof, the hook of the safety belt is hung on the roof guardrail or other fixed building structures. And, an anti-falling device also needs to be installed beside the building to provide protection for construction workers who accidentally fall.
[0004] In the related art, traditional anti-falling devices are all equipped with buffer springs to play a buffering role to ensure the safety of construction workers. However, due to the large impact force during falling, it is easy for the traditional buffer springs to deform repeatedly, resulting in secondary injuries to construction workers. Utility Model Content
[0005] In view of this, the embodiments of this application provide a safety anti-falling device for building construction to solve the problem in the related art that due to the large impact force during falling, it is easy for the traditional buffer springs to deform repeatedly, resulting in secondary injuries to construction workers.
[0006] To achieve the above object, the embodiments of this application provide the following technical solutions:
[0007] A safety anti-falling device for building construction, comprising:
[0008] A protective bottom plate, with protective baffles arranged around the protective bottom plate, and buffer sponges arranged on the protective bottom plate;
[0009] The first support legs, the number of the first support legs is multiple, and the first support legs are arranged at the four corner positions of the bottom surface of the protective bottom plate; both sides of the bottom ends of the first support legs are hinged and connected with abutting plates through torsion springs;
[0010] The second support leg, the number of the second support legs being equal to that of the first support legs, the second support legs being sleeved outside the first support legs, and the second support legs being slidably connected to the first support legs; vertical flanges are arranged on the inner wall surface of the second support legs at equal intervals, and a buffer spring is arranged on the bottom surface of the second support legs; wherein,
[0011] The bottom end of the first support leg is connected to the buffer spring, and the first support leg contacts the flange through the abutting plate.
[0012] In some possible implementation manners, a vertical hole communicating with the inside thereof is arranged on the side wall of the second support leg;

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.
[0029] Such as Figures 1-4As shown in the figure, the safety anti-falling device for building construction provided by the embodiment of the present application includes a protective bottom plate 100, a first support leg 300, and a second support leg 500. Among them, protective baffles 200 are provided at the four peripheral edges of the protective bottom plate 100, and the protective bottom plate 100 and the protective baffles 200 together form the main structure of the safety anti-falling device. A buffer sponge 110 is also fixedly arranged on the upper surface of the protective bottom plate 100. If a construction worker who stumbles falls from a high altitude, he will fall into the space formed by the protective bottom plate 100 and the protective baffles 200, and the buffer sponge 110 on the upper surface of the protective bottom plate 100 provides the first layer of buffering effect for the construction worker.
[0030] At the four corner positions on the bottom surface of the protective bottom plate 100, first support legs 300 are provided. The first support legs 300 and the protective bottom plate 100 are fixedly connected structures. Preferably, the two can be welded together or integrally formed. At both sides of the bottom end of the first support leg 300, abutting plates 400 are hinged, and the first support leg 300 is hinged to the abutting plate 400 through a torsion spring. In the non-force mode, the elastic force provided by the torsion spring will cause the abutting plate 400 to rotate in the outward direction, and the abutting plate 400 is located above the bottom end of the first support leg 300.
[0031] The second support leg 500 is a support leg structure with a hollow structure design. The inner diameter of the second support leg 500 is larger than the outer diameter of the first support leg 300. The second support leg 500 is sleeved outside the first support leg 300, and the second support leg 500 is slidably connected to the first support leg 300. Preferably, the inner width of the second support leg 500 is adapted to the bottom width of the first support leg 300, and the abutting plates 400 are hinged on both sides in the length direction of the bottom end of the first support leg 300.
[0032] In this embodiment, a plurality of vertically distributed flanges 600 are fixedly arranged on the inner wall surface of the second support leg 500. Preferably, the flanges 600 and the second support leg 500 can be integrally formed. In addition, a buffer spring 700 is also arranged inside the second support leg 500. The buffer spring 700 is fixedly connected to the bottom surface of the second support leg 500, and the buffer spring 700 is vertically arranged inside the second support leg 500.
[0033] During actual use, the bottom end of the first support leg 300 abuts against the top end of the buffer spring 700. The first support leg 300 also abuts against the flanges 600 arranged on the inner wall surface of the second support leg 500 through the abutting plates 400 hinged on both sides in the length direction of its bottom end.
[0034] In the safety anti-falling device for building construction provided in the embodiment of the present application, when a construction worker slips and falls onto the protective base plate 100, the first support leg 300 will squeeze the buffer spring 700 and move downward. During the movement, the abutment plate 400 will abut against the flange 600 on the inner wall of the second support leg 500 under the elastic force of the torsion spring. As the first support leg 300 continues to move downward, the abutment plate 400 will abut against different flanges 600 to achieve the damping function until the buffer spring 700 is compressed to a balanced state. At this time, Figure 4 As shown, the abutment plate 400 is clamped between adjacent flanges 600 under the elastic force of the torsion spring, so that the first support leg 300 and the protective base plate 100 are in a stationary state, thereby preventing the buffer spring 700 from being deformed repeatedly to cause secondary injuries to the construction workers.
[0035] In some embodiments, the side wall of the second support leg 500 is further provided with a vertical hole 510 connected to the inside thereof, and the first support leg 300 is hingedly connected to the abutment plate 400 through a rotating shaft 800, and a torsion spring is sleeved on the rotating shaft 800. An extension shaft 810 is further provided on the side surface of the bottom end of the first support leg 300, and the extension shaft 810 is fixedly connected to the rotating shaft 800. Specifically, the rotating shaft 800 is fixedly provided at the hinge point of the abutment plate 400, and accordingly, an axis hole is provided at the bottom end of the first support leg 300, and the rotating shaft 800 of the abutment plate 400 is passed through the axis hole to realize a structure hingedly connected to the first support leg 300.
[0036] Since the extension shaft 810 is fixedly connected to the rotating shaft 800, when the abutment plate 400 rotates, the rotating shaft 800 and the extension shaft 810 are driven to rotate simultaneously. The outer diameter of the extension shaft 810 is slightly smaller than the width of the vertical hole 510, and the extension shaft 810 passes through the vertical hole 510 and is located outside the second support leg 500. Preferably, a screwing handle 820 is also fixedly provided at the end of the extension shaft 810 located outside the second support leg 500.
[0037] In actual use, if a construction worker falls onto the anti-fall device after slipping, the first support leg 300 will drive the abutment plate 400 and squeeze the buffer spring 700, and move downward inside the second support leg 500. When the buffer spring 700 reaches the balance point, the abutment plate 400 will be clamped between the upper and lower adjacent flanges 600. If the safety anti-fall device is to be used again, the screwing handle 820 can be turned to control the abutment plate 400 to be separated from the gap between the flanges 600, so that the buffer spring 700 can be restored to its original state, and the first support leg 300 and the protective bottom plate 100 and other structures can be supported upward again.
[0038] Preferably, a buffer pad 900 may also be provided at the bottom end of the second support leg 500. The buffer pad 900 may be an elastic rubber structure or an inflatable buffer air cushion. The second support leg 500 contacts the ground through the buffer pad 900, which can provide a third layer of cushioning for construction workers who accidentally fall, thus providing the maximum cushioning to the greatest extent.
