Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment for steel structure building construction, in particular to an anti-falling component for the roof of a steel structure building. Background Art

[0002] In steel structure buildings, color steel tiles are usually laid on the roof, and personnel stand on the color steel tiles for various operations. However, because the color steel tiles on the top of such buildings are relatively smooth, personnel are prone to falling during operations, resulting in safety accidents.

[0003] In order to improve the above problems, those skilled in the art will correspondingly set up a protection device, which connects the safety rope on the worker's body to the protection device to achieve anti-falling. Such a device can refer to the anti-falling device and roof system with the publication number CN207597911U. It fixes a frame on the roof, sets a fixing ring on the frame, connects a steel cable through the fixing ring, and personnel hook the safety rope tied to their bodies on the steel cable. When accidentally falling, the safety protection is achieved through the cooperation of the steel cable and the safety rope. However, through actual use verification, such products have drawbacks in their structures, which are reflected in: 1. The grasping surface at the bottom of the frame is small, resulting in low overall strength. When multiple constructors are connected to the steel cable at the same time, if a danger occurs, the frame is likely to become loose, causing secondary injuries; 2. When a person falls, because neither the steel cable nor the safety rope has extensibility or elasticity, a large local pulling force will be exerted on the fallen person at the moment of tensioning, which is likely to cause injuries to the waist and neck of the person; 3. The pulling force generated at the moment of such tensioning will not only impact the person, but also impact the frame or the steel cable, and it is easy for the frame to fall off the roof.

[0004] Aiming at the drawbacks in the prior art, according to the actual construction requirements, the technical problem that needs to be solved urgently at present is: how to design a set of anti-falling components for the roof of a steel structure building through technical improvement, which can be stably installed and fixed on the building roof surface, and can achieve a certain degree of elastic buffering when a person accidentally falls during construction, preventing injuries to personnel and equipment at the moment of falling.

Detailed implementation mode

[0023] The following provides a detailed description of the present utility model. Those familiar with this technology can easily understand other advantages and effects of the present utility model from the content disclosed in this specification.

[0024] As shown in the attached drawing, a steel structure building roof anti-falling component has the following specific implementation structure: It includes a fixed seat 1, and a columnar fixed edge 11 is arranged on the fixed seat 1; it should be noted that the above-mentioned fixed seat 1 is not independently arranged, and it is an integrally formed structure with the color steel tile. Usually, when purchasing and assembling the color steel tile, a group of color steel tiles with a fixed seat 1 are selected for assembly after a certain width interval, or at the edge of the top of the building, a group of color steel tiles with a fixed seat 1 are arranged about 3 meters away from the eaves and gables for assembly.

[0025] A locking member 2 is arranged on the columnar fixed edge 11. As Figure 5 shown, the locking member 2 is formed by buckling a left-side member 21 and a right-side member 22 and then locking them with bolts; in this embodiment, a docking groove 23 is arranged on the left-side member 21, and a docking protrusion 24 is arranged on the right-side member 22. The docking protrusion 24 is inserted and matched with the docking groove 23; a T-shaped sliding groove 25 is arranged on the top surface of the left-side member 21, and a locking bolt is arranged in the T-shaped sliding groove 25 for fixing the support plate 3. In this embodiment, four locking members 2 are used as a group to fix the support plate 3. To improve the assembly strength and stability, the width of the fixed surface 26 on the top surface of the T-shaped sliding groove 25 can be increased, thereby increasing the extrusion contact surface. During actual assembly, the support plate 3 can be appropriately adjusted in the T-shaped sliding groove 25. However, to prevent the locking bolt from coming out of the T-shaped sliding groove 25, the present utility model also arranges blocking nuts 27 at both ends of the T-shaped sliding groove 25 to realize the adjustment limit of the locking bolt through the blocking nuts 27.

[0026] When the present utility model sets the support plate 3, the support plate 3 is designed as two pieces arranged crosswise, namely an upper support plate 31 and a lower support plate 32. Bending portions are provided on both the upper support plate 31 and the lower support plate 32. Such bending portions can achieve buffering when subjected to tensile force. When the upper support plate 31 and the lower support plate 32 are stacked, an upper buffer block 33 is arranged between the two support plates. The upper buffer block 33 is made of rubber material, and its function is to achieve vertical buffering, and at the same time, it can prevent noise caused by friction between the upper support plate 31 and the lower support plate 32.

[0027] The present utility model also sets a U-shaped seat 5 on the upper part of the support plate 3. The U-shaped seat 5 can be obtained by cutting a U-shaped steel. In this embodiment, two through holes are provided on the U-shaped seat. A through pipe 51 is penetrated through the through holes. The through pipe 51 extends to the left and right ends of the U-shaped seat 5 and forms a locking surface 52 outside the U-shaped seat 5. The through pipe 51 is restricted by the locking surface 52 to prevent the through pipe 51 from slipping out of the through holes. The function of setting the through pipe 51 in the present utility model is to increase the contact area between the steel cable 50 and the U-shaped seat 5, so that the pulling is more stable. Those skilled in the art can expand the through holes to two or more, and realize the pulling through multiple steel cables 50 together, so that the pulling is more stable.

[0028] The author's more key design is that a T-shaped rod 4 penetrates through the U-shaped seat 5 and the two support plates 3. External threads are provided on the lower section of the T-shaped rod 4, and the external threads are connected with a threaded cylinder 42. A blocking surface 41 is also provided on the threaded cylinder 42. For the convenience of screwing, a force application surface is provided on the blocking surface 41, or the blocking surface is arranged at the bottom of the threaded cylinder 42, and a hexagonal hole is provided on the blocking surface 41 for a wrench to be inserted. A buffer spring 43 is arranged between the blocking surface 41 and the lower support plate 32 in the present utility model. As a further improvement, a lower buffer block 44 is also arranged between the buffer spring 43 and the lower support plate 32. The lower buffer block 44 is made of rubber material, and its function is to achieve vertical buffering. When subjected to external pulling force, the buffer spring 43 first deforms with a large deformation amount, and then the lower buffer block 44 receives a secondary impact with a smaller deformation amount, so as to achieve energy absorption in the vertical direction.

[0029] A sliding block 6 is arranged on the steel cable 50 in the present utility model. The sliding block 6 is composed of a fastening member I 61 and a fastening member II 62 buckled together. Locking edges 63 are provided on both the fastening member I 61 and the fastening member II 62 for bolt locking and fixing the two. A linear bearing 64 is also arranged between the fastening member I 61 and the fastening member II 62. The steel cable 50 penetrates through the linear bearing 64. When an external person uses this device, he pulls the sliding block 6 to slide on the steel cable 50 through a pulling rope 76, which can reduce the friction force to the lowest level and basically will not bring pulling resistance to the external person.

[0030] A fixing frame 7 is arranged on the top surface of the sliding block 6. One end of the fixing frame 7 is connected to one end of a bending plate 71, and a pulling seat 73 is fixed to the other end of the bending plate 71. In this embodiment, the pulling seat 73 is a sheet metal bending part. A locking end 74 is arranged on the pulling seat 73. The locking end 74 is connected to the bending plate 71 and a flexible buffer is achieved during connection through a pulling seat buffer block 75. A pulling rope 76 is provided with a knot or a blocking piece 77 inside the pulling seat, and the end buffer spring 72 is constrained within the pulling seat 73 through the knot or the blocking piece 77.

[0031] With the above structural arrangement, when the device is in use, the pulling rope 76 is connected to the safety rope of an external construction worker through a connecting buckle. If a construction worker accidentally falls, the protection principle is as follows: The pulling rope 76 serves as the direct force-bearing member and is first subjected to a pulling impact. The pulling rope 76 transmits the force to the end buffer spring 72. After squeezing the end buffer spring 72, the force is transmitted to the pulling seat 73, and then to the bending plate 71 and the fixing frame 7. The bending plate 71 and the fixing frame 7 absorb energy through deformation. Then, the force is transmitted to the support plate 3 through the sliding block 6, the steel cable 50, and the U-shaped seat 5. When transmitting the force to the support plate 3, it must pull the buffer spring 43 through the T-shaped rod 4, and the energy in the vertical direction is absorbed through the deformation of the buffer spring 43. In the vertical direction, the force is transmitted to the support plate 3 through the deformation of the buffer spring 43 and the lower buffer block 44 in sequence. Since the support plate 3 is bent, its overall strength can be effectively guaranteed during force pulling, avoiding deformation or damage.

[0032] The structure of the utility model is novel in design. When in use, a person or a small device can be connected to the anti-falling component on the roof of this steel structure building. When being pulled by the fall of a person or a device, multiple levels of energy absorption can be achieved in sequence through the end buffer spring 72, the bending plate 71, the fixing frame 7, the buffer spring 43, and the lower buffer block 44 during the momentary impact, minimizing the impact on the person or the small device and the anti-falling component on the roof of this steel structure building itself, avoiding irreversible damage to the neck or waist of the person, and effectively ensuring the life safety of the operators on the ground and the top surface of the building. It is an ideal anti-falling component for the roof of a steel structure building.
