Description

Technical Field

[0001] The utility model relates to the technical field of scaffolding, in particular to a high-rise scaffolding attachment device. Background Art

[0002] In construction, attached lifting scaffolds are widely used to ensure the safety of construction workers and provide necessary construction protection. However, in actual applications, existing attached lifting scaffolds face many challenges during installation and use, especially when the main structure of the building has a floor height of more than 3 meters. The traditional practice is to install wall supports on the exterior wall of the building structure to fix the scaffolding. However, since residential structures often have each floor higher than 3 meters, this fixing method has too large a distance between the upper and lower fixing points when encountering structures with a floor height of more than 3 meters. This is not only not conducive to the stable connection of the attached lifting scaffold, but also seriously affects its safety, thereby posing a safety hazard during the construction process.

[0003] Therefore, it is necessary to provide a high-rise scaffolding attachment device that can adapt to various floor heights, especially the main structure of the building with a floor height of more than 3 meters, which can effectively reduce the distance between the fixed points, so that the attached lifting scaffolding can be reliably supported under different floor height conditions, thereby effectively ensuring construction safety and reducing unnecessary risks. Utility Model Content

[0004] The utility model provides a high-rise scaffolding attachment device to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A high-rise scaffolding attachment device includes a scaffolding and a concrete slab. The concrete slab is provided with an attachment device, the attachment device comprising a crossbeam fixed to the concrete slab. Two channel steels are mounted on one end of the crossbeam facing the scaffolding. Lifting connection seats are slidably mounted on the two channel steels. The lifting connection seats are provided with wall-mounted supports, which are connected to the scaffolding. A diagonal brace is also connected between the upper end of each channel steel and the crossbeam. The wall-mounted supports are a commonly used connection structure for lifting scaffolding and are not intended to be the sole limitation herein. The diagonal brace, crossbeam, and channel steels are connected by welding, bolts, or other means.

[0007] Preferably, the groove sides of the two channel steels are arranged opposite to each other, the flat side of each channel steel is provided with a slide groove, and a plurality of screw holes are provided on both sides of the groove of each channel steel.

[0008] Preferably, the lifting connection seat includes a mounting plate, and L-shaped connecting plates are provided on both sides of the mounting plate. Each connecting plate is inserted into the slide groove on the corresponding channel steel. The mounting plate is provided with a plurality of screw holes 2 corresponding to screw holes 1, and the connecting plate is provided with screw holes 3 corresponding to screw holes 2. The wall-mounted support and the lifting connection seat are both installed and connected by screwing bolts into screw holes 1, 2, and 3. The bolts are threadedly connected to the nuts, and a short steel pipe is put on the nut to prevent the nut wrench from colliding with the support rod when tightening the bolt, thereby preventing the nut from being tightened. The lifting connection seat is driven to rise and fall by the connecting plate moving up and down along the slide groove, thereby achieving up and down height adjustment of the lifting connection seat and the wall-mounted support, thereby improving the stability and safety of scaffolding installed at different floor heights.

[0009] Preferably, a square tube is provided between the concrete slab and the crossbeam, the concrete slab is provided with a plurality of pre-buried holes, and the square tube and crossbeam are provided with four screw holes corresponding to the pre-buried holes. The concrete slab, square tube, and crossbeam are connected and fixed by screws. The square tube is used to adjust the height difference between the concrete slab and the crossbeam at different positions. By replacing square tubes of different heights to fill the gap between the crossbeam and the concrete slab, the crossbeam can be more stably fixed to the concrete slab, while also making the force distribution on the concrete slab more uniform and dispersed, reducing the force pressure on the screws.

[0010] Preferably, a reinforcing plate is provided between the lower bottom surface of the concrete slab and the screw rod, for distributing the pulling force of the lower end of the screw rod to the bottom surface of the concrete slab through the reinforcing plate, thereby increasing the force-bearing area of ​​the bottom of the concrete slab and improving the overall stability of the attachment device.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] The utility model arranges a crossbeam on the concrete slab and installs channel steel on the crossbeam, and cooperates with the slide groove and bolt connection to enable the lifting connection seat to slide up and down in the slide groove of the channel steel, thereby adjusting the connection height of the wall support and the scaffolding, ensuring that a stable connection can be maintained in building structures with different floor heights; at the same time, by arranging square tubes and embedded holes between the concrete slab and the crossbeam, and filling them with square tubes of different heights, the height difference between the crossbeam and the concrete slab is effectively adjusted, so that the crossbeam is more firmly fixed on the concrete slab, the stress pressure of the screw is reduced, and the overall stability of the device is further enhanced; in addition, the setting of the reinforcement plate disperses the tension of the lower end of the screw to the bottom surface of the concrete slab, increases the stress area of ​​the bottom of the concrete slab, and improves the overall safety and reliability of the attachment device, thereby significantly improving the safety and stability of the attached lifting scaffold in high-rise building construction.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] Reference Figure 1-3 A high-rise scaffolding attachment device includes a scaffolding 2 and a concrete slab 1. The concrete slab 1 is provided with an attachment device 3. The attachment device 3 includes a crossbeam 4 fixed to the concrete slab 1. Two channel steels 5 are installed on the crossbeam 4 facing one end of the scaffolding 2. A lifting connection seat 6 is slidably installed on the two channel steels 5. The lifting connection seat 6 is provided with a wall-mounted support 7. The wall-mounted support 7 is connected to the scaffolding 2. A diagonal brace 8 is also connected between the upper end of each channel steel 5 and the crossbeam 4. The wall-mounted support 7 is a commonly used connection structure for the lifting scaffolding 2 and is not the only one defined here. The diagonal brace 8, the crossbeam 4 and the channel steel 5 are connected by welding, bolts 17, etc.

[0019] The groove sides of the two channel steels 5 are arranged opposite to each other, and a sliding groove 14 is provided on the flat side of each channel steel 5. A plurality of screw holes 18 are provided on both sides of the groove of each channel steel 5.

[0020] The lifting connection base 6 includes a mounting plate 15, with L-shaped connecting plates 16 on both sides. Each connecting plate 16 is inserted into the chute 14 on the corresponding channel steel 5. The mounting plate 15 is provided with a plurality of second screw holes 19 corresponding to the first screw holes 18, and the connecting plate 16 is provided with a third screw hole 20 corresponding to the second screw hole 19. The wall-mounted support 7 and the lifting connection base 6 are both installed and connected by screwing bolts 17 into the first screw hole 18, the second screw hole 19, and the third screw hole 20. The bolts 17 are threadedly connected to the nuts. A short steel pipe is placed over the nuts to prevent the nut wrench from colliding with the support rod when tightening the bolts 17, thereby preventing the nut from being tightened. The connecting plates 16 move up and down along the chute 14, driving the lifting connection base 6 to rise and fall, thereby achieving vertical height adjustment of the lifting connection base 6 and the wall-mounted support 7, thereby improving the stability and safety of the scaffolding 2 installed at different floor heights.

[0021] A square tube 9 is provided between the concrete slab 1 and the crossbeam 4. The concrete slab 1 is provided with a plurality of pre-buried holes 12. The square tube 9 and the crossbeam 4 are provided with four screw holes 11 corresponding to the pre-buried holes 12. The concrete slab 1, the square tube 9, and the crossbeam 4 are connected and fixed by screws 13. The square tube 9 is used to adjust the height difference between the concrete slab 1 and the crossbeam 4 at different positions. By replacing the square tube 9 with different heights to fill the gap between the crossbeam 4 and the concrete slab 1, the crossbeam 4 can be more stably fixed to the concrete slab 1, and the force distribution on the concrete slab 1 is more evenly dispersed, reducing the force pressure on the screws 13.

[0022] A reinforcing plate 10 is provided between the lower bottom surface of the concrete slab 1 and the screw 13. The reinforcing plate 10 is used to disperse the tension of the lower end of the screw 13 to the bottom surface of the concrete slab 1 through the reinforcing plate 10, thereby increasing the force-bearing area of ​​the bottom of the concrete slab 1 and improving the overall stability of the attachment device 3.

[0023] When using the present invention, square tubes 9 are installed at different heights on the concrete slab 1, and crossbeams 4 are secured to the tubes 9 via screws 13. The height of the connecting plate 16 within the chute 14 is adjusted according to the floor level and the height of the scaffolding 2, thereby adjusting the position of the mounting plate 15. After the mounting plate 15 is moved to the desired height, the wall-mounted support 7 is mounted on the mounting plate 15 using bolts 17. The mounting plate 15 and connecting plate 16 are then secured to the two channel steels 5 to prevent the mounting plate 15 from moving up and down. Finally, the scaffolding 2 is connected to the wall-mounted support 7 to complete the installation.

[0024] The utility model can adjust the connection height between the wall-mounted support 7 and the scaffolding 2, ensuring a stable connection in building structures of different heights, and effectively improving the safety and stability of the attached lifting scaffolding 2 in high-rise building construction.
