Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and specifically relates to a liftable horizontal isolation and protection device. Background Technology

[0002] During the upward construction of a building structure, horizontal isolation and protection measures are required at horizontal openings such as elevator shafts to prevent the construction of the upper main structure from affecting the decoration and finishing work below. Common practices for horizontal isolation and protection include laying safety nets on cantilevered steel sections or installing upper tension steel cables above the safety nets. If the method of laying safety nets on cantilevered steel sections is used, the steel sections are fixed to the lower structure of the horizontal isolation and protection. This method requires pre-installation of embedded parts in the concrete structure, followed by fixing the steel sections to these pre-installed parts. This approach not only involves complex construction procedures but also results in significant steel waste. Furthermore, because steel sections are hard, objects striking the horizontal isolation and protection can cause deformation of the steel sections, affecting their load-bearing capacity.

[0003] When using conventional upward-pull steel wire ropes, the original anchor points become unsuitable as the building height increases. As the horizontal isolation protection is raised, new steel wire rope anchor points need to be installed on the structure. Because the steel wire rope length is fixed and cannot be easily adjusted, in actual construction, as the structural height increases, it is common to encounter situations where the steel wire rope length is insufficient, necessitating frequent installation of new anchor points, which consumes significant manpower and resources. Therefore, there is an urgent need to develop a liftable horizontal isolation protection device. Utility Model Content

[0027] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below. Technical features in various embodiments of this utility model can be combined appropriately without conflict.

[0028] like Figure 1 As shown, as a preferred embodiment of the present invention, this embodiment provides a liftable horizontal isolation and protection device, including a winch 1, a winch support 2, a pulley block structure 3, a horizontal isolation and protection structure 4, and a connecting rope 5.

[0029] In the device provided by this utility model, the horizontal isolation and protection structure 4 is arranged between the main structures on both sides, and the winch 1, winch bracket 2, and pulley block structure 3 are symmetrically fixed on the main structures on both sides of the horizontal isolation and protection structure 4.

[0030] like Figure 2 and Figure 3 As shown, a winch bracket 2 is fixed to each side of the main structure, and a winch 1 is fixed to the outside of the winch bracket 2. In this embodiment, the winch bracket 2 includes a frame reinforcement structure 21 and diagonal bracing rods 22. The frame reinforcement structure 21 is made of 12 angle steels welded into a whole, and the four corners of the base of the winch 1 are fixed to the winch bracket 2 with bolts.

[0031] To increase the overall structural stability and prevent the winch support 2 from becoming unstable during the upward pulling of the horizontal isolation and protection structure 4, several reinforcing angle steels 211 are provided in this embodiment. The length of the reinforcing angle steels 211 is greater than the length of the angle steels in the frame reinforcement structure 21. The frame reinforcement structure 21 is reinforcedly connected to the main structure through the reinforcing angle steels 211, and the reinforcing angle steels 211 are fixedly connected to the vertical surface of the main structure through expansion bolts. To ensure the stability and safety of the structure under shear force, the connection between the winch support 2 and the main structure needs to meet shear resistance requirements. In other embodiments, the connection between the winch support 2 and the main structure can also be pre-embedded. Considering the force situation when the winch 1 handle is rotated, the reinforcing angle steels 211 are generally erected vertically.

[0032] To further enhance the stability of the winch support 2, a diagonal brace 22 is also installed. One end of the diagonal brace 22 is fixed to one of the angle steels in the winch support 2, and the other end is fixed to the horizontal plane of the main structure. Considering the stability requirements, the connection is usually made by welding.

[0033] In the device provided by this utility model, the horizontal isolation and protection structure 4 includes an isolation net 41, an isolation frame 42, and an isolation plate. The isolation net 41 is fixedly installed at a fixed distance below the isolation frame 42. When an object falls from the construction site above, the isolation net 41 can effectively buffer the impact. The fixed distance in the middle is to increase the stability between the isolation net 42 and the isolation frame 42, and reduce the possibility that the isolation net 41 will fall off the isolation frame 42 due to the large mass and strong impact of the falling object.

[0034] Because galvanized square tubing has high compressive and tensile strength, can withstand significant external forces, and possesses good impact resistance and corrosion resistance, making it suitable for construction environments, the isolation frame 42 in this embodiment is constructed using galvanized square tubing spliced ​​together as a single unit. In other embodiments, the isolation frame 42 can also be made using angle steel, channel steel, H-beams, or other steel materials.

[0035] In this embodiment, an isolation board is laid on the isolation frame 42. The isolation board can be corrugated board, wooden template or other recyclable materials. It mainly serves as a buffer to prevent sharp objects with large impact force from falling from above from directly contacting the isolation frame 42 and the isolation net 41, thereby reducing the wear and tear on the isolation frame 42 and the isolation net 41.

[0036] The two ends of the isolation frame 42 are fixedly connected to two connecting ropes 5 respectively. The other ends of the two connecting ropes 5 pass through the pulley block structure 3 and are fixedly connected to the shaft of the winch 1. The winch 1 can be a hand-cranked winch or an electric winch. When the handle of the winch 1 is turned, the handle drives the shaft to rotate, thereby raising or lowering the connecting ropes 5, thus realizing the raising or lowering of the horizontal isolation protection structure 4.

[0037] like Figure 2 and Figure 4 As shown, the pulley block structure 3 is fixedly installed on the horizontal surface of the main structure below the winch bracket 2. To ensure that the pulley block structure 3 fits tightly with the main structure and does not shift when lifting the horizontal isolation and protection structure 4, the support frame 31 of the pulley block structure 3 needs to be strengthened to secure it to the main structure. Generally, nails can be used to nail the base of the support frame 31 to the main structure. In other embodiments, other fixing methods that ensure no relative displacement between the pulley block structure 3 and the main structure can also be used, such as welding or using expansion bolts. The base of the support frame 31 is a right angle that fits with the edge of the horizontal surface of the main structure. One end is fixedly installed on the side of the horizontal surface of the main structure, and the other end is fixedly installed on the horizontal surface of the main structure. Three fixed pulleys 32 with parallel rotating shafts are fixedly installed on the support frame 31. The three fixed pulleys 32 can distribute the load among themselves, making the force on a single pulley smaller, reducing the risk of wear and tear. The cooperation of the three pulleys can also reduce the vibration of the connecting rope 5 caused by the movement of the horizontal isolation and protection structure 4 to a certain extent. The fixed pulley 32 is installed below the outer contour of the support frame 31. This design ensures that when the connecting rope 5 moves on the fixed pulley 32, it is blocked by the support frame 31 on both sides, thus preventing the connecting rope 5 from slipping off the fixed pulley 32. Figure 5 As shown, the heights of the three fixed pulleys 32 increase sequentially, with the lowest fixed pulley 32 parallel to the side of the horizontal plane of the main structure. The other ends of the two connecting ropes 5, one end of which is fixedly connected to the horizontal isolation and protection structure 4, pass through the three fixed pulleys 32 and are fixed to the shaft of the winch 1. The three fixed pulleys 32 cooperate to change the direction of movement of the connecting ropes 5 and also serve to separate the connecting ropes 5 from the main structure, preventing contact between them. Since the main structure is generally a rough cement surface, this design reduces the excessive wear and tear on the connecting ropes 5 due to high friction with the main structure.

[0038] The embodiments described above are merely preferred solutions of this utility model, and are not intended to limit the scope of this utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this utility model. Therefore, all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of this utility model.
