Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a vertical connection device for external steel plate protective netting and its construction method. Background Technology

[0002] For projects with high floors, large spans, wide spacing between external frame columns, no infill walls, and a semi-concealed frame glass curtain wall exterior, the scaffolding for frame construction often uses cantilevered steel pipe scaffolding as both construction scaffolding and external protective scaffolding. To improve safety, steel plate safety netting is often added to the outside of the scaffolding. Existing external scaffolding steel plate safety netting is connected to the external scaffolding in various ways, but primarily uses horizontal connectors, neglecting vertical connectors. If horizontal connectors cannot be used due to structural constraints, there is no effective method for vertical connection.

[0003] Therefore, with the premise of horizontal connection, this connection device can also improve the overall safety and stability of the external steel plate protective net. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a vertical connection device for external steel plate protective netting and its construction method. Under the premise of horizontal connection, the overall safety and stability of external steel plate protective netting can also be improved by using this connection device.

[0005] The vertical connection device and construction method for the external steel plate protective netting provided by this invention adopt the following technical solution:

[0006] In a first aspect, a vertical connection device for an external steel plate protective net includes a buckle and a connecting assembly fixed on a steel pipe of the external steel plate. The connecting assembly includes a connecting arm disposed on the buckle, the connecting arm extending outward from the wall and inclined downward, and a connecting rod connected to the end of the connecting arm away from the buckle. The connecting rod is fixed horizontally to the protective net.

[0007] By adopting the above technical solution, the protective netting is connected and installed on the steel pipe of the scaffold steel plate through the connecting arm, realizing the vertical connection of the protective netting on the scaffold steel plate. This avoids the situation where the protective netting cannot be connected by horizontal connectors due to the influence of the structure.

[0008] Furthermore, the connecting assembly also includes a movable rod arranged horizontally on the connecting arm, and a sleeve is provided at the lower end of the connecting arm in the horizontal direction. The movable rod passes through the sleeve and is connected to the connecting rod. A fastening bolt for fixing the movable rod is provided on the sleeve.

[0009] By adopting the above technical solution, the movable rod and the connecting rod are welded and fixed. By pushing the movable rod, the protective net can be moved, and the distance between the protective net and the outer frame steel plate can be adjusted, making it convenient to adjust the position of the protective net.

[0010] Furthermore, the lower side of the connecting arm is provided with multiple lifting rods, which are arranged vertically. The lower end of each lifting rod is provided with a support tube, through which the movable rod passes.

[0011] By adopting the above technical solution, the movable rod passes through the support pipe, and the hanger can support the movable rod, enabling it to withstand greater loads, preventing the movable rod from tilting, and making the installation more stable.

[0012] Furthermore, the spacing between the multiple suspension rods is the same.

[0013] By adopting the above technical solution, the spacing between the hangers is the same, making the supporting force of the hangers on the movable rod more uniform.

[0014] Furthermore, the lower end of the buckle is provided with a connecting plate in the vertical direction, and an adjusting tube is rotatably provided on the connecting plate. The end of the movable rod passes through the adjusting tube and is threaded into the adjusting tube. The end of the sleeve is provided with a guide bar, and a guide groove is provided on the side wall of the movable rod. The guide bar is located in the guide groove to prevent the movable rod from rotating. Rotating the adjusting tube causes the movable rod to move horizontally to adjust the position of the protective net.

[0015] By adopting the above technical solution, rotating the adjusting tube allows the movable rod to move horizontally to adjust the position of the protective net. After the movable rod and the connecting rod are welded and fixed, rotating the adjusting tube allows the movable rod to move horizontally, making the adjustment of the protective net position more convenient.

[0016] Furthermore, the end of the movable rod away from the connecting rod is provided with a limiting block to prevent the movable rod from disengaging from the adjusting tube.

[0017] By adopting the above technical solution, when the movable rod moves outward a certain distance, the limiting block will abut against the adjusting tube, preventing the movable rod from continuing to move outward and falling off the adjusting tube.

[0018] Furthermore, the limiting block is threaded onto the movable rod.

[0019] By adopting the above technical solution, the position of the limit block on the movable rod can be adjusted by rotating the limit block, thereby controlling the movement stroke of the movable rod.

[0020] Furthermore, the surface of the connecting rod is serrated.

[0021] By adopting the above technical solution, the serrated connecting rod can be better connected to the protective net, reducing the possibility of the connecting rod falling off the protective net.

[0022] Firstly, a method for vertically connecting external steel plate protective netting is described, comprising the following steps:

[0023] S1. Fix the buckle to the steel pipe with bolts, and then weld the connecting arm to the buckle at an angle.

[0024] S2. Pass the front end of the movable rod through the adjusting tube, the support tube, and the sleeve in sequence;

[0025] S3. Fix the connecting rod to the protective net and hoist the protective net to the installation position;

[0026] S4. Weld the end of the movable rod to the connecting rod and fix it. Move the movable rod by rotating the adjusting tube until the distance between the protective net and the outer frame steel plate is appropriate. Use fastening bolts to fix the movable rod to the sleeve.

[0027] In summary, the present invention has at least one of the following beneficial effects: Compared with the prior art, the connecting device of the present invention can solve the technical problem of vertical connection of the external scaffold steel plate protective net. The connecting device can be used in the construction of external scaffold steel plate protective nets, and it has strong versatility and wide application range. Attached Figure Description

[0031] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0032] The following is in conjunction with the appendix Figure 1 The present invention will be described in further detail below.

[0033] This invention discloses a vertical connection device for an external steel plate protective net and its construction method. (Refer to...) Figure 1The vertical connection device for the protective netting on the scaffolding steel plate includes a buckle 1 fixed to the steel pipe of the scaffolding steel plate and a connecting component 2. The connecting component 2 includes a connecting arm 21 set on the buckle 1. The connecting arm 21 extends outward from the wall and is inclined downward. A connecting rod 3 is connected to the end of the connecting arm 21 away from the buckle 1. The connecting rod 3 is fixed horizontally to the protective netting. The protective netting is connected and installed on the steel pipe of the scaffolding steel plate through the connecting arm 21, realizing the vertical connection of the protective netting on the scaffolding steel plate. This avoids the situation where the protective netting cannot be connected by horizontal connectors due to the influence of the structure.

[0034] In this embodiment, the connecting assembly 2 further includes a movable rod 22 arranged horizontally on the connecting arm 21. The lower end of the connecting arm 21 is provided with a sleeve 23 in the horizontal direction. The movable rod 22 passes through the sleeve 23 and is connected to the connecting rod 3. The sleeve 23 is provided with fastening bolts for fixing the movable rod 22. The movable rod 22 and the connecting rod 3 are welded and fixed. By pushing the movable rod 22, the protective net can be moved to adjust the distance between the protective net and the outer frame steel plate, so as to facilitate the adjustment of the position of the protective net.

[0035] In this embodiment, the lower side of the connecting arm 21 is provided with multiple suspension rods 24. The suspension rods 24 are arranged in a vertical direction. The lower end of the suspension rod 24 is provided with a support tube 25. The movable rod 22 passes through the support tube 25. The suspension rods 24 can support the movable rod 22, so that the movable rod 22 can withstand a larger load, avoid the movable rod 22 from tilting, and make the installation more stable.

[0036] In this embodiment, the multiple suspension rods 24 are spaced at the same distance, and the spacing between the suspension rods 24 is the same, so that the supporting force of the suspension rods 24 on the movable rod 22 is more uniform.

[0037] In this embodiment, the lower end of the buckle 1 is provided with a connecting plate 4 in the vertical direction, and an adjusting tube 41 is rotatably provided on the connecting plate 4. The end of the movable rod 22 passes through the adjusting tube 41 and is threadedly engaged with the adjusting tube 41. The end of the sleeve 23 is provided with a guide strip 27, and a guide groove 28 is provided on the side wall of the movable rod 22. The guide strip 27 is located in the guide groove 28 to prevent the movable rod 22 from rotating. Rotating the adjusting tube 41 causes the movable rod 22 to move horizontally to adjust the position of the protective net. After the movable rod 22 and the connecting rod 3 are welded and fixed, the movable rod 22 can be moved in the horizontal direction by rotating the adjusting tube 41, making the adjustment of the position of the protective net more convenient.

[0038] In this embodiment, the end of the movable rod 22 away from the connecting rod 3 is provided with a limiting block 26 to prevent the movable rod 22 from detaching from the adjusting tube 41. When the movable rod 22 moves outward a certain distance, the limiting block 26 will abut against the adjusting tube 41 to prevent the movable rod 22 from continuing to move outward and falling off the adjusting tube 21.

[0039] In this embodiment, the limiting block 26 is threaded onto the movable rod 22. By rotating the limiting block 26, the position of the limiting block 26 on the movable rod 22 can be adjusted, and the movement stroke of the movable rod 22 can be controlled.

[0040] In this embodiment, the surface of the connecting rod 3 is serrated, which allows for a better connection with the protective net and reduces the possibility of the connecting rod 3 falling off the protective net.

[0041] A method for vertically connecting external steel plate protective netting includes the following steps:

[0042] Step 1: Fix the buckle 1 to the steel pipe with bolts, and then weld the connecting arm 21 to the buckle 1 at an angle;

[0043] Step 2: Pass the front end of the movable rod 22 through the adjusting tube 41, the support tube 25 and the sleeve 23 in sequence;

[0044] Step 3: Fix connecting rod 3 to the protective netting and hoist the protective netting to the installation position;

[0045] Step 4: Weld the end of the movable rod 22 to the connecting rod 3 and move the movable rod 22 by rotating the adjusting tube 41 until the distance between the protective net and the outer frame steel plate is appropriate. Use fastening bolts to fix the movable rod 22 to the sleeve 23.
