Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a building construction safety anti-fall mechanism. Background Technology

[0002] Fall arrestors, as crucial facilities for preventing falling objects from heights, play a vital role in building construction. During construction, large amounts of debris or building materials often fall unexpectedly from higher floors, posing a serious threat to the lives of workers on lower floors. Therefore, specialized facilities are urgently needed to prevent these falling objects and effectively protect the lives of workers on lower floors. Furthermore, these fall arrestors also provide protection for construction workers, acting as a buffer and shield in the event of an accidental fall.

[0003] Currently, existing fall arrest mechanisms mainly consist of a fall arrest frame fixed to the building structure, a fall arrest net installed within the fall arrest frame, and several connecting components connecting the fall arrest frame and the fall arrest net. These connecting components include hook bolts and lock nuts. Specifically, the hook bolts pass through the fall arrest frame and are then threaded onto the lock nuts to secure them to the frame. Finally, the fall arrest net is attached to the hook bolts, completing the installation. However, this installation method has significant drawbacks. It requires a large number of connecting components, which undoubtedly increases the workload of assembling and disassembling the fall arrest mechanism considerably. Furthermore, due to the hook-and-loop installation method, the fall arrest net cannot effectively limit its movement, making it prone to accidental detachment from the hook bolts due to external factors, thus posing a safety hazard. Based on these problems, this improved solution has been developed. Utility Model Content

[0004] The purpose of this utility model is to provide a safety fall prevention mechanism for building construction. This safety fall prevention mechanism can facilitate the easy assembly and disassembly of the fall prevention net and can form a stable connection with the fall prevention net, thereby reducing the workload of assembly and disassembly and ensuring construction safety.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a building construction safety fall prevention mechanism, including a fall prevention frame and a fall prevention net set in the center of the fall prevention frame. Several connecting components are movably arranged on the fall prevention frame and distributed around the fall prevention net. Each group of connecting components has several hanging points for connecting the fall prevention net. A limiting structure is formed on one side of each group of connecting components to cooperate with the connecting components. The connecting components move in a connected state to connect with the fall prevention net and a limiting state to restrict the fall prevention net from detaching from the hanging points. Each group of connecting components is connected to a fixing component to fix the connecting components in the limiting state.

[0006] By adopting the above technical solution, the fall arrestor frame is fixed to the building structure. Then, the connecting components are switched to the connected state to hook onto the fall arrestor net via hanging points. Next, the connecting components are switched from the connected state to the limiting state, and then fixed in the limiting state by the set fixing components. This prevents accidental detachment at the hook points between the fall arrestor net and the hanging points, thus forming a stable connection with the fall arrestor net. By setting up a single set of connecting components, multiple connections with the fall arrestor net can be achieved, thereby reducing the number of connecting components used and enabling convenient assembly and disassembly of the fall arrestor net. This reduces the workload of assembly and disassembly and ensures construction safety.

[0007] The connection assembly is further configured such that: the connecting component includes a rotating shaft rotatably mounted on the fall arrestor frame and a connecting pipe fixedly connected to the rotating shaft; the hanging points are located on the connecting pipe and are arranged horizontally along the axis of the connecting pipe.

[0008] By adopting the above technical solution, the position of the hanging point is changed by rotating the connecting pipe, thereby switching the connecting component between the connected state and the limit state.

[0009] The further configuration is as follows: a long strip-shaped connecting groove is formed on the connecting pipe, extending horizontally along the axis of the connecting pipe, and the hanging point is integrally disposed on the side wall of the connecting groove and arranged along the length direction of the connecting groove.

[0010] By adopting the above technical solution, and by opening a connecting groove and combining it with an integrated structure, the connecting pipe structure can be formed on the pipe by simply laser cutting ordinary existing pipe fittings, which is cheaper and more convenient to process.

[0011] Further configuration: the hanging point is a hook, the limiting structure is a limiting strip fixed to the fall arrestor frame and located on one side of the rotation direction of the connecting pipe, the orthographic projection path of the limiting strip facing the connecting pipe intersects the connecting pipe, and the distance formed between the limiting strip facing the connecting pipe and the connecting pipe is less than the diameter of the fall arrestor net to limit the fall arrestor net from detaching from the hook.

[0012] By adopting the above technical solution, after the fall protection net is attached to the hook through the hook tip, the connecting tube is rotated to move the hook tip to the side corresponding to the limiting strip. The limiting strip then abuts against the outside of the hook tip, thereby preventing the fall protection net from detaching from the hook and thus achieving a stable connection.

[0013] The fixing component is further configured such that: the fixing component includes a ratchet fixedly mounted on the rotating shaft and rotating with the connecting pipe, and a pawl rotatably mounted on one side of the ratchet, the pawl having the potential energy to engage the ratchet.

[0014] By adopting the above technical solution, the ratchet and pawl work together to achieve unidirectional rotation of the connecting tube, so that the connecting tube can only drive the fall protection net to rotate towards the side of the limiting strip, in order to cooperate with the limiting strip to form a limit, thereby achieving a stable connection.

[0015] A further configuration is provided: an elastic element is connected to the pawl to drive the pawl to engage the ratchet.

[0016] By employing the above technical solution, the elastic element applies an elastic force to the pawl engaging the ratchet, thereby reducing the probability of accidental disengagement between the pawl and the ratchet, thus enhancing the structure's safety. To separate the pawl from the ratchet, the worker simply pries the pawl off the ratchet.

[0017] The further configuration is as follows: the connecting tube is provided with a dial hole for rotating the connecting tube, and a plurality of dial holes are arranged around the center of the connecting tube.

[0018] By adopting the above technical solution, when the connecting pipe needs to be rotated, the worker can easily rotate the connecting pipe by inserting the hook into the dial hole and then pulling the hook, making the operation more convenient.

[0019] In summary, this utility model has the following beneficial effects: it enables convenient disassembly and assembly of the fall protection net and forms a stable connection with it, thereby reducing the workload of disassembly and assembly and ensuring construction safety.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings.

[0023] refer to Figures 1 to 4A construction safety fall arrest mechanism includes a fall arrest frame 1 and a fall arrest net 2 disposed at the center of the fall arrest frame 1. Several connecting components 3 are movably disposed on the fall arrest frame 1, distributed around the fall arrest net 2. Preferably, there are four sets of connecting components 3 arranged in a rectangular pattern. Each set of connecting components 3 has several attachment points 31 for connecting the fall arrest net 2, and a limiting structure is formed on one side of each set of connecting components 3 to cooperate with the connecting components 3. The connecting components 3 can move in a connected state to the fall arrest net 2 and in a limited state where the limiting structure prevents the fall arrest net 2 from detaching from the attachment points 31. Each set of connecting components 3 is connected to a fixing component 5 to fix the connecting components 3 in the limited state. The fall arrest frame 1 can be connected to the building structure via expansion bolts.

[0024] The connecting assembly 3 includes a rotating shaft 32 rotatably mounted on the fall arrestor frame 1 and a connecting pipe 33 fixedly connected to the rotating shaft 32. The hanging points 31 are disposed on the connecting pipe 33 and arranged horizontally along the axis of the connecting pipe 33. An elongated connecting groove 6 extending horizontally along the axis of the connecting pipe 33 is formed on the connecting pipe 33. The hanging points 31 are integrally disposed on the side wall of the connecting groove 6 and arranged along the length of the connecting groove 6; the hanging points 31 are hooks.

[0025] The limiting structure is a limiting strip 4 fixed to the fall arrestor frame 1 and located on one side of the rotating direction of the connecting pipe 33. The orthographic projection path of the limiting strip 4 facing the connecting pipe 33 intersects the connecting pipe 33. The distance between the limiting strip 4 facing the connecting pipe 33 and the connecting pipe 33 is less than the diameter of the fall arrestor net 2, thus preventing the fall arrestor net 2 from detaching from the hook. The fall arrestor net 2 is made of woven nylon rope.

[0026] The fixing component 5 includes a ratchet 51 fixedly mounted on the rotating shaft 32 and rotating with the connecting tube 33, and a pawl 52 rotatably mounted on the fall arrestor frame 1 and located on one side of the ratchet 51 via the main shaft. The pawl 52 has the potential energy to engage the ratchet 51, and its height is above the ratchet 51. An elastic element (not shown in the figure) is connected to the pawl 52 to drive it to engage the ratchet 51. The elastic element is a torsion spring fitted onto the main shaft and fixedly connected at both ends to the pawl 52 and the fall arrestor frame 1, respectively. The connecting tube 33 has a number of holes 7 for rotating the connecting tube 33, which are distributed around the center of the connecting tube 33.
