The attached lifting scaffolding equipment and its climbing technology have become an indispensable and important part in the construction of high-rise and super-high-rise buildings.

[0048] This embodiment provides an attached scaffold climbing and attachment device based on irregular structural layer construction. It includes:

[0049] 1. The steel truss column 1, as the main supporting member of the climbing attachment device of the attached scaffolding 9, is mainly used to install the first attachment support 8 and the hanging parts. It is tightly connected with the climbing track 10 of the attached scaffolding 9 by using tension bolts 6, so as to bear the vertical and horizontal loads that need to be transmitted from the attached scaffolding 9 during the climbing process.

[0050] Preferably, the steel truss column 1 adopts a rectangular channel steel with a length of 4m, and a connecting steel plate is used on the back of the channel steel for welding connection to form a stable spatial lattice system to resist stress deformation or distortion during the load-bearing process.

One end is fixedly connected to the steel truss column 1 at a 90° right angle to the auxiliary stiffener, and the other end is rigidly connected to the main diagonal brace channel steel 31 by welding, so that the deadweight load and dynamic load of the attached scaffolding 9 are transferred to the floor slab 7 through the steel truss column 1 and the main diagonal brace channel steel 31 to achieve the purpose of dispersing the concentrated load.

[0052] Preferably, the bottom horizontal channel steel 2 is formed of a lattice steel structure by combining 16# channel steels, and is fixedly connected to the floor slab 7 via tension bolts 6 over the entire length.

[0053] 3. The diagonal bracing channel steel 3 includes a main diagonal bracing channel steel 31, a left diagonal bracing channel steel 32 and a right diagonal bracing channel steel 33. The main diagonal bracing channel steel 31 is used to connect the steel truss columns 1, the bottom horizontal channel steel 2 and the horizontal supporting channel steel 4 to form a vertical main frame structure. Its two ends are rigidly connected to the steel truss columns 1 and the bottom horizontal channel steel 2 by welding, respectively, to bear the vertical and horizontal loads from the steel truss columns 1 and the attached scaffolding 9 during the climbing process, and firmly constrain them to the fixed working surface to prevent overturning.

[0054] Preferably, the main diagonal bracing channel steel 31 uses 10# channel steel with a length of about 4m as a diagonal bracing member, one end of which is rigidly connected to the steel truss column 1 by welding, and the angle between the two is preferably about 30°, and the other end is welded to the bottom horizontal channel steel 2 on the ground by welding with the help of a connecting steel plate, and the angle between the two is preferably about 60°. The middle part is rigidly connected with a certain number of horizontal channel steels 4 according to the load-bearing requirements to enhance its overall stability;

[0056] 4. The two ends of the horizontal support channel steel 4 are rigidly connected to the steel truss column 1 and the main diagonal bracing channel steel 31 by welding, so as to effectively reduce the actual working span of the steel truss column 1 and the main diagonal bracing channel steel 31, and at the same time bear part of the horizontal load to increase the overall stability of the device.

[0057] Preferably, the horizontal supporting channel steel 4 is made of 10# channel steel, and according to actual conditions, two channels are preferably provided, located at 1 / 3 and 2 / 3 of the length of the middle of the main diagonal bracing channel steel respectively.

[0058] 5. The channel steel pad 5 is a rectangular cross-section channel steel with a certain number of stiffeners arranged inside. It is placed below the bottom horizontal channel steel 2 and above the floor slab 7 of the layer, and plays a role in receiving the force transmission and transition between the bottom horizontal channel steel 2 and the floor slab 7.

[0059] Preferably, 1 to 3 stiffening plates are arranged in the transverse and longitudinal directions inside the channel steel pad 5 to improve the compressive strength of the channel steel pad 5 and play a role in transferring the upper load to the floor slab 7.

[0060] 6. The tension bolts 6 are composed of three parts, namely bolts, nuts and washers, and are used to reinforce the connecting components, so that the bolt connection between the bottom horizontal channel steel 2, the channel steel pad 5 and the floor slab 7 is tighter, and the overall stability of the climbing attachment device of the attached scaffolding 9 is better.

[0061] Preferably, the tension bolts 6 are high-strength bolts, and their screw rods, nuts and washers are all made of high-strength steel represented by No. 45 steel.

[0062] It should be noted that in the present application, when the attached scaffolding is difficult to find an effective attachment point for climbing due to the inward-retracted structure of the upper floor or the excessive clear height, by installing the attached scaffolding climbing attachment device based on the irregular structural layer construction on the current floor, a strong attachment point can be provided for the attached scaffolding during climbing, so that the attached scaffolding can be effectively climbed when facing the inward-retracted structure of the upper floor or the excessive clear height;

[0063] In addition, further functional extensions can be made based on the research of this utility model. When faced with an overhanging superstructure or an extremely large net height of a floor, consideration can be given to adjusting the inclination angle of the steel truss columns or increasing the working length of the steel truss columns, while using other connecting components to ensure its overall stability, thereby providing a safe and effective way for the attached scaffold to climb, thereby achieving a breakthrough in the climbing technology of the attached scaffold during the construction of high-rise and super-high-rise buildings.
