Abstract
Description
Technical Field
[0001] This utility model relates to the field of safety rope suspension technology, specifically to a secondary structure construction docking suspension device. Background Technology
[0002] In the construction of secondary structures in frame-structured factory buildings, high-altitude operations are generally involved. Because the main structure lacks facilities for suspending safety belts or ropes, and the scaffolding used in construction cannot achieve the desired high-hanging, low-use of safety ropes, safety accidents frequently occur during secondary structure construction. If the effective use of safety protective equipment during secondary structure construction is not addressed, the construction work will remain stuck in a cycle of self-inspection and external inspection for safety hazard rectification, making it impossible to guarantee the construction period and inevitably affecting the construction quality due to intermittent construction.
[0003] Therefore, a secondary structure construction docking suspension device is proposed to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to provide a reusable, easy-to-install, low-cost secondary structure construction docking suspension device that is particularly suitable for large-span frame structure construction operations.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] This utility model provides a secondary structure construction docking suspension device, including a left hanger, a right hanger, and a connector, wherein the connector is connected between the lower parts of the left hanger and the right hanger.
[0007] Preferably, the connector includes a sleeve, a insertion rod, and a pin.
[0008] The sleeve is a straight tube with pin holes on its peripheral wall;
[0009] The insertion rod is a straight rod with multiple insertion holes on its peripheral wall, and one end of the straight rod is inserted into the insertion hole at one end of the straight tube;
[0010] The pin is inserted into the pin hole and the insertion hole.
[0011] Preferably, the insertion hole is provided with an internal thread, and the pin is provided with an external thread that engages with the internal thread.
[0012] Preferably, the left and right hanging parts are mirror-symmetrical.
[0013] Preferably, the left hanging component includes a vertical rod and a hanging rod.
[0014] The upper end of the vertical rod is vertically connected to one end of the hanging rod, the lower part of the vertical rod is connected to one end of the connector, and the other end of the connector is connected to the lower part of the right hanging piece.
[0015] Preferably, a rope-receiving loop is connected to the lower part of the vertical rod.
[0016] Preferably, a connecting rod connects the vertical rod and the rope receiving ring.
[0017] Preferably, the lower end of the connecting rod is away from the vertical rod.
[0018] Preferably, the angle between the connecting rod and the vertical rod is 135°.
[0019] Preferably, a chain connects the vertical rod and the rope receiving ring.
[0020] Preferably, a rope is connected between the pin and the sleeve to prevent the pin from being lost.
[0021] Due to the adoption of the above technical solutions, the advantages of this utility model are as follows:
[0022] 1. This utility model, through the combined fixing action of the left and right hanging parts, can effectively utilize the pre-reserved tie bolt holes on the main structural beam for fixing. It can solve the problem of no effective fixing point for safety ropes when workers are working at height in the secondary structure construction of frame structure factory buildings in the context of edge and high-altitude working environments. It can realize the effective use of safety protection equipment, avoid construction accidents, and promote the smooth progress of secondary structure construction with guaranteed quality and quantity.
[0023] 2. The installation and removal of this utility model can be achieved by simply inserting and removing one pin and one plug, without the need for any installation tools, making the installation and removal operation convenient.
[0024] 3. This utility model can be disassembled and reused after construction is completed.
[0025] 4. After installation, the left and right hanging rods of this utility model are inserted into the tie bolt holes, providing reliable suspension fixing points on both sides (especially avoiding stress concentration caused by bending deformation near the tie bolt holes due to lateral pulling of the safety rope on the same side of a single-sided suspension, which can easily lead to breakage). The pins are set to reliably lock the connection state of the left and right hanging rods, realizing the reliable connection of this utility model on the structural beam.
[0026] 5. This utility model can be selected for individual use as needed, and multiple sets can be used together in the construction process of large-span frame structures to provide effective, reliable and continuous safety rope suspension fixing points over a large area, making the construction process smooth and flexible.
[0027] 6. This utility model has a simple structure, is easy to process and manufacture, and has low cost. Attached Figure Description

[0035] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.
[0036] The specific implementation method is described below:
[0037] This utility model provides an embodiment of a secondary structure construction docking suspension device 100, see [link to embodiment]. Figure 1 It includes a left hanging part 10, a right hanging part 20 and a connector 30, wherein the connector 30 is connected between the lower parts of the left hanging part 10 and the right hanging part 20.
[0038] The connector 30 includes a sleeve 31, a rod 33, and a pin 32. The sleeve 31 is a straight tube with a pin hole 311 on its peripheral wall. The rod 33 is a straight rod with multiple insertion holes 331 on its peripheral wall, and one end of the rod is inserted into the insertion hole 312 at one end of the straight tube. The pin 32 is inserted into the pin hole 311 and the insertion holes 331. (See also...) Figure 1 , Figure 2 .
[0039] The left hanging member 10 and the right hanging member 20 are mirror-symmetrical. The left hanging member 10 includes a vertical rod 11, a hanging rod 12, a rope receiving ring 13, and a connecting rod 14 connecting the vertical rod 11 and the rope receiving ring 13. The upper end of the vertical rod 11 is perpendicularly connected to one end of the hanging rod 12, and the lower end of the vertical rod 11 is perpendicularly connected to one end of the sleeve 31 of the connector 30. The end of the insertion rod 33 of the connector 30 away from the sleeve 31 is perpendicularly connected to the lower part of the right hanging member 20. The hanging rod 12 is oriented in the same direction as the sleeve 31. See [reference needed]. Figure 1 , Figure 2 .
[0040] In this embodiment, the included angle between the connecting rod 14 and the vertical rod 11 is 135°; the length of the hanging rod 12 is 100mm; the left hanging part 10 and the right hanging part 20 are both made of steel bars with a diameter of 14mm; this utility model is applicable to structural beams 2 with a cross-sectional width of 200mm-350mm.
[0041] In use, the pin 32 is removed from the pin hole 311 of the sleeve 31, allowing the insertion rod 33 to be pulled out of the sleeve 31, thus separating the left hanger 10 from the right hanger 20 (this step can be omitted if the left hanger 10 and right hanger 20 are not connected); then, the left hanger 10 and right hanger 20 are respectively inserted into the two ends of the tie bolt holes on the target structural beam 2 via the hanging rod 12 (while simultaneously inserting the insertion rod 33 into the sleeve 31); finally, the pin 32 is inserted into the pin hole 311 and the insertion hole 331 to complete the installation. See [link to installation instructions]. Figure 3 When working at heights, connect the safety belt to the rope catch 13 and then normal construction can begin.
[0042] When multiple sets of this utility model are used together on a large-span frame structure beam 2, firstly, according to the above installation method, fix and connect multiple suspension devices 100 provided by this utility model to multiple target structural beams 2 respectively. Then, tighten the safety rope 4 between two opposite rope receiving loops 13. Finally, connect the spring buckle of the safety belt attached to the human body to the safety rope 4. Construction work can then begin over a larger area along the extension direction of the safety rope 4. See [link to relevant documentation]. Figure 1 , Figure 3 , Figure 4 .
