Description

Technical Field

[0001] This utility model relates to the field of safety construction device technology, and more specifically, to a temporary fixing device for safety rope netting in steel structure construction. Background Technology

[0002] During the fabrication and installation of bridge steel structures, the large cross-sections of the components and the high elevation often require workers to operate at heights, posing a risk of falls. However, due to the inherent safety and quality requirements of bridge steel structures, devices for securing safety ropes and nets cannot be welded onto the bridge body. Therefore, the current common practice is to use single clips or single bolts to directly fasten the safety net or rope to the protruding parts of the steel structure flanges. This type of fixing structure is highly susceptible to detachment after prolonged use and vibration. To address these issues, there is an urgent need for a temporary fixing device for safety ropes and nets during steel structure construction. Utility Model Content

[0003] In view of the above problems, the purpose of this utility model is to provide a temporary fixing device for safety rope netting in steel structure construction, which is installed on the flange plate of the steel structure to solve the problem of unstable suspension of safety rope netting during the processing and installation of bridge steel structure.

[0004] This utility model provides a temporary fixing device for safety rope netting in steel structure construction, comprising a pair of flange clamps, a connecting plate, a safety rope hanging post, and a safety net clamp. The flange clamping plate includes an upper plate, a lower plate, and a connecting plate connecting the edges of the upper plate and the lower plate. The upper plate and the lower plate are parallel and their center lines are aligned. A central threaded hole is provided in the middle of the upper plate. The pair of flange clamping plates are respectively snapped onto the two sides of the upper flange plate of the H-beam of the steel structure and are symmetrical about the center line of the upper flange plate. The safety rope hanging post is fixed to one end of the connecting plate, and the connecting plate is provided with through holes corresponding to the two threaded holes respectively; The safety net clamp includes two pressure plates, and two insertion slots with the same spacing as the two through holes are provided on the pressure plates; The connecting plate is disposed on the upper part of the two upper plates, and the two pressure plates are disposed above the connecting plate in sequence, with the sockets of the two pressure plates facing each other. A safety net is sandwiched between the two pressure plates. The two pressure plates, the connecting plate, and the two upper plates are fixed together by central hole bolts passing through corresponding sockets, through holes, and central threaded holes.

[0005] One possible solution is that the distance between the upper plate and the lower plate is equal to the thickness of the upper flange plate.

[0006] One possible solution is that the width and length of the upper plate are greater than the width and length of the lower plate, respectively, and end threaded holes are provided at both ends of the upper plate. The upper plate is fixed to the upper flange plate by end bolts passing through the end threaded holes.

[0007] One option is that the width of the connecting plate is less than the distance between the two end threaded holes.

[0008] One option is that the width of the pressure plate is the same as the width of the connecting plate, and the socket includes a semi-circular hole disposed on the center line of the length direction of the pressure plate and an elongated hole opened from the semi-circular hole to the long edge of the pressure plate. The diameter of the circular hole and the width of the elongated hole are both equal to the diameter of the through hole.

[0009] One option is to tighten a first nut onto the bolt portion in the center hole between the safety net clamp and the connecting plate.

[0010] One option is to tighten a second nut onto the central bolt portion at the upper part of the safety net clamp.

[0011] One option is that the safety rope hanging post includes a steel pipe welded to the upper end of the connecting plate and closed, with two ear plates provided on the side wall of the steel pipe.

[0025] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Example 1 like Figures 1-4 As shown in the figure, the temporary fixing device for steel structure construction safety rope net proposed in this embodiment can be installed on the flange plate of the steel section of the steel structure for suspending safety ropes and safety nets, and can also be installed on both sides of other long strip plates for suspending nets or ropes.

[0027] The temporary fixing device for safety rope netting in steel structure construction proposed in this embodiment mainly includes a pair of flange clamping plates 1, a connecting plate 2, and a safety net clamping plate 4 arranged sequentially from bottom to top on the upper flange plate 8 of an H-beam or I-beam. A safety rope hanging post 3 is fixed to one end of the connecting plate 2. The pair of flange clamping plates 1 are used to clamp the two sides of the upper flange plate 8 along its length. The connecting plate 2 is used to pull and fix the pair of flange clamping plates 1 to the upper flange plate 8. The safety net clamping plate 4 is used to press and fix the safety net. The safety rope hanging post 3 is used to suspend the safety rope.

[0028] The flange clamp 1 includes an upper plate 11, a lower plate 12, and a connecting plate 13 connecting the edges of the upper plate 11 and the lower plate 12. The upper plate 11 and the lower plate 12 are parallel and their center lines are aligned. A central threaded hole 14 is provided in the middle of the upper plate 11. A pair of flange clamps 1 are respectively clamped on both sides of the upper flange plate 8 of the H-beam of the steel structure and are symmetrical about the center line of the upper flange plate 8.

[0029] In other words, the upper plate 11, the lower plate 12, and the connecting plate 13 constitute a U-shaped flange clamp 1. Each flange clamp 1 can be inserted into the edge of the upper flange plate 8. The upper plate 11 and the lower plate 12 respectively fit against the upper and lower sides of the upper flange plate 8, and the connecting plate 13 is close to the edge of the upper flange plate 8. The two flange clamps 1 are symmetrically clamped onto both sides of the upper flange plate 8 of the H-beam and locked in place. The threaded holes 14 on the two upper plates 11 are used by the connecting plate 2 to connect the two flange clamps 1, so that the two flange clamps 1 are pulled together relative to each other to clamp onto the upper flange plate 8.

[0030] The connecting plate 2 can be a rectangular steel plate with a length slightly larger than the width of the upper flange plate 8. The connecting plate 2 not only connects the two flange clamps 1 but also supports the safety rope hanging post 3. The safety rope hanging post 3 is fixed to one end of the connecting plate 2. The connecting plate 2 has through holes 21 corresponding to the two central threaded holes 14, for connecting the two flange clamps 1. The diameter of the through holes can be about 2mm larger than the diameter of the central threaded holes.

[0031] The safety net clamp 4 may include two pressure plates 41, and each pressure plate 41 has two insertion slots 42 spaced at the same distance as the two through holes 21. The safety net is clamped between the two pressure plates 41, increasing the fixing area of ​​the safety net, making the safety net firmly fixed, and preventing it from being pulled and damaged during use.

[0032] During installation, the connecting plate 2 is placed on the upper part of the two upper plates 11, and the two pressure plates 41 are placed above the connecting plate 2 in sequence. The sockets 42 of the two pressure plates 41 are arranged opposite each other. A safety net is sandwiched between the two pressure plates 41. The two pressure plates 41, the connecting plate 2 and the two upper plates 11 are fixed together by the central bolts 7 that pass through the corresponding sockets 42, through holes 21 and central threaded holes 14.

[0033] The connecting plate 2 is horizontally placed on the top surface of the upper plate 11 of the pair of flange clamping plates 1. The through hole 21 of the connecting plate 2 is aligned with the corresponding threaded hole 14. At this point, a safety net can be placed on the connecting plate 2. The center bolt 7 is screwed into the through hole 21 and the threaded hole 14 to initially connect the pair of flange clamping plates 1 and the connecting plate 2. One pressure plate 41 is placed on the upper part of the connecting plate 2, and the corresponding center bolt 7 is inserted into the socket 42. The other pressure plate 41 is placed on the upper part of the safety net, and the corresponding center bolt 7 is inserted into the socket 42. The sockets 42 of the two pressure plates 41 are opposite each other, and the two pressure plates 41 clamp the safety net in the middle. After tightening the center bolt 7, the two pressure plates 41, the safety net, the connecting plate 2, and the flange clamping plates 1 are fastened together as a whole and firmly installed on the upper flange plate 8. The center bolt 7 can also be slightly screwed into the upper flange plate 8 for further stable installation. The length of the center bolt 7 is equal to or slightly longer than the sum of the thicknesses of the upper plate 11, the connecting plate 13, and the two pressure plates 41.

[0034] In one specific embodiment of this utility model, the distance between the upper plate 11 and the lower plate 12 is equal to the thickness of the upper flange plate 8, ensuring that the flange clamping plate 1 can be stably fixed on the upper flange plate 8.

[0035] In one specific embodiment of this utility model, the width and length of the upper plate 11 are greater than those of the lower plate 12, respectively. Threaded holes 15 are provided at both ends of the upper plate 11, and the upper plate 11 is fixed to the upper flange plate 8 by end bolts passing through the threaded holes 15. The fixing of the upper plate 11 to the upper flange plate 8 by the end bolts on both sides further prevents the entire device from shaking or shifting.

[0036] In one specific embodiment of this utility model, the width of the connecting plate 2 is less than the distance between the two end threaded holes 15. The connecting plate 2 covers the upper part of the upper plate 11 of the two flange clamping plates 1 and is located between the two end threaded holes 15, without affecting the fastening installation of the end threaded holes 15.

[0037] In one specific embodiment of this utility model, the width of the pressure plate 41 is the same as the width of the connecting plate 2. The insertion port 42 includes a semi-circular hole disposed on the center line of the length direction of the pressure plate 41 and an elongated hole extending from the semi-circular hole to the long edge of the pressure plate 41. The diameter of the circular hole and the width of the elongated hole are both equal to the diameter of the through hole 21. The width and length of the insertion port 42 not only facilitate the insertion with the central bolt 7 but also ensure a stable insertion that will not fall off. After the two pressure plates 41 are inserted, an elongated hole is formed around the central bolt 7, clamping the safety net in the middle and preventing it from falling off.

[0038] In one specific embodiment of this utility model, a first nut 5 is screwed onto the central hole bolt 7 between the safety net clamping plate 4 and the connecting plate 2. After the connecting plate 2 covers the two upper plates 11, the central hole bolt 7 can be passed through the mesh of the safety net and the first nut 5, and screwed onto the corresponding through hole 21 and central threaded hole 14. Then, the first nut 5 is tightened to secure the connecting plate 2 to the pair of flange clamping plates 1, ensuring that the pair of flange clamping plates 1 can be firmly fixed on the upper flange plate 8 before the safety net clamping plate 4 is installed, facilitating the installation of the two pressure plates 41. The central hole bolt 7 is a fully threaded fine-pitch bolt, and its length is greater than the sum of the thicknesses of the upper plate 11, the connecting plate 13, and the two pressure plates 41.

[0039] In one specific embodiment of this utility model, a second nut 6 is screwed onto the upper central bolt 7 portion of the safety net clamping plate 4. The second nut 6 can be tightened after the two pressure plates 41 are inserted to secure the clamping of the two pressure plates 41. Through the tightening of the second nut 6 and the first nut 5, the two pressure plates 41, the safety net, the connecting plate 2, and the pair of flange clamping plates 1 are fixed as a whole.

[0040] In one specific embodiment of this utility model, the safety rope hanging post 3 includes a steel pipe 31 with its upper end closed and welded to the connecting plate 2. Two ear plates 32 are provided on the side wall of the steel pipe 31, with a certain distance between them. The distance is set according to the needs of the safety rope hanging. The ear plates 32 are perpendicular to the edge of the upper flange plate 8 and face the upper flange plate 8. The central hole of the two ear plates 32 is used to thread the safety rope. The portion of the safety rope located on both sides of the ear plates 32 is clamped using U-shaped clamps 33 that match the thickness of the safety rope. The outer circumference of the U-shaped clamps 33 is larger than the central hole of the ear plates 32, which can prevent the safety rope from shifting left and right and causing danger.

[0041] In one specific embodiment of this utility model, at least two temporary fixing devices for the steel structure construction safety rope net are installed on the upper flange plate 8 according to the width of the safety net and construction needs. Several temporary fixing devices for the steel structure construction safety rope net are equally spaced on the upper flange plate 8 of an H-beam to fix the entire safety net. Several temporary fixing devices for the steel structure construction safety rope net can also be installed on adjacent H-beams to stably fix larger safety nets.

[0042] Example 2 Figure 5 This is a schematic diagram of the structure of the connecting plate 2 according to Embodiment 2 of this utility model; Figure 6 This is a schematic diagram of the structure of the pressure plate 41 according to Embodiment 2 of the present invention; like Figure 5 and Figure 6 As shown in the figure, the temporary fixing device for steel structure construction safety rope net provided in this embodiment, based on embodiment 1, has evenly arranged insertion slots 42 on the pressure plate 41 and evenly arranged through holes 21 on the connecting plate 2 in order to adapt to upper flange plates 8 of different widths.

[0043] The connecting plate 2 has multiple through holes 21, allowing for flexible selection of two suitable through holes 21 for connection based on the spacing of the threaded holes 14 on the two flange clamps 1. The pressure plate 41 has multiple sockets 42, allowing for flexible selection of two suitable sockets 42 for insertion based on the spacing of the two central bolts 7. This design offers flexible installation and a wide range of applications.
