Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a wall-attached support used for installing an attached lifting scaffold. Background Art

[0002] In the construction of high-rise buildings, in order to improve the efficiency and safety of the construction process, attached lifting scaffolding is usually used as an external protective frame on the periphery of the building. The traditional method of erecting attached lifting scaffolding is to set up an I-beam cantilever beam on the top floor of the building, and then set up a steel pipe leveling frame on the cantilever beam as the force point of the climbing frame to assemble the climbing frame. This erection process has the following disadvantages during construction: 1. The U-shaped clip used to fix the cantilever beam needs to be drilled on the floor. According to the force calculation, hundreds of holes need to be drilled on the floor, which is very destructive to the steel bars and embedded casing in the floor structure; 2. When erecting the steel pipe leveling frame, the erection personnel need to work at a height of 30 meters, and the safety measures can only rely on safety ropes, which is very dangerous; 3. When assembling the attached lifting scaffolding, when fixing the assembled part in the horizontal direction, it can only rely on the steel wire rope to be tied to the floor, which has the risk of overturning.

[0003] When installing traditional attached lifting scaffolding, usually a φ50mm hole is drilled on the main structure of the building, and then the M32 bolts are implanted with anchor glue, and then the wall-mounted bracket is installed. The traditional wall-mounted bracket is composed of a square steel base plate, a crossbeam, and a diagonal brace. It is fixed to the wall by bolts passing through the reserved holes on the square steel base plate. The defects of this method are: ① The bolts and concrete are bonded to each other with anchor glue, and the frame will vibrate when climbing, causing the bolts to loosen, affecting the stability and safety of the frame. ② Because the bolts are bonded to the concrete, the bolts cannot be removed for secondary use, resulting in material waste. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a wall-mounted support for the installation of an attached lifting scaffold. The wall-mounted support overcomes the defects of the traditional climbing frame erection. The climbing frame is erected using the wall-mounted support to ensure the stability of the entire system, avoid deviation or shaking, and prevent the climbing frame from overturning and falling during use, thereby providing necessary safety guarantees for high-rise building construction.

[0005] In order to solve the above technical problems, the utility model provides a wall-attached support for the installation of an attached lifting scaffold, comprising a wall-attached support, a roller frame, a roller, an adjustable support rod, a connecting block, an anti-fall hook, a star wheel and a swing pin, wherein the wall-attached support is arranged on the main structure of the building through a through-wall screw, the roller frame is arranged on the front side of the wall-attached support, the rollers are arranged at intervals on the roller frame and are arranged at intervals up and down, the wheel surface of the roller protrudes from the front side of the roller frame, the adjustable support rod is hinged to the front end of the wall-attached support through a first pin shaft, and the adjustable support rod is located above the wall-attached support to support the attached lifting scaffold, the connecting block is arranged on the bottom surface of the front end of the wall-attached support, the anti-fall hook and the star wheel are hinged to the bottom end of the connecting block through a second pin shaft, and the anti-fall hook and the star wheel are fixedly connected, the swing pin is hinged to the bottom end of the connecting block through a second pin shaft and a buckle is provided at the front end, and the swing pin is rotated to make the front end buckle snap into or out of the wheel surface of the star wheel.

BRIEF DESCRIPTION OF THE DRAWINGS

[0009] The present invention is further described in detail below in conjunction with the accompanying drawings and implementation examples:

[0010] Figure 1 The utility model is a schematic diagram of a wall-attached support for installing an attached lifting scaffold. DETAILED DESCRIPTION

[0011] Implementation example Figure 1As shown, the utility model comprises a wall-mounted support for installation of an attached lifting scaffold, comprising a wall-mounted support 1, a roller frame 2, a roller 3, an adjustable support rod 4, a connecting block 5, an anti-fall hook 6, a star wheel 7 and a swing pin 8. The wall-mounted support 1 is arranged on a main building structure 12 through a through-wall screw 11, the roller frame 2 is arranged on the front side of the wall-mounted support 1, the roller 3 is arranged at intervals on the roller frame 2 and arranged at intervals up and down, the wheel surface of the roller 3 protrudes from the front side of the roller frame 2, and the adjustable support rod 4 is arranged through a first pin shaft. 41 is hinged to the front end of the wall-mounted bracket 1, and the adjustable supporting rod 4 is located above the wall-mounted bracket 1 to support the top-attached lifting scaffolding. The connecting block 5 is arranged on the bottom surface of the front end of the wall-mounted bracket 1. The anti-fall hook 6 and the star wheel 7 are hinged to the bottom end of the connecting block 5 through the second pin shaft 61, and the anti-fall hook 6 and the star wheel 7 are fixedly connected. The pendulum needle 8 is hinged to the bottom end of the connecting block 5 through the second pin shaft 61 and a buckle is provided at the front end. The pendulum needle 8 is rotated to make the front end buckle snap into or out of the wheel surface of the star wheel 7.

[0012] Preferably, the adjustable support rod 4 is a telescopic support rod. The length can be easily adjusted by the telescopic support rod, which is convenient for supporting the climbing frame at different positions.

[0013] Preferably, the front bottom of the anti-fall hook 6 is an inclined surface 62. The inclined surface can avoid interference when the climbing frame is lifted, ensuring the normal lifting of the climbing frame.

[0014] When erecting the attached lifting scaffolding, firstly, erect a floor-type steel pipe leveling frame on the top plate of the building basement to the third floor of the building, and start assembling the climbing frame of the attached lifting scaffolding from the third floor of the building, and assemble the climbing frame to the position of the wall-mounted support; in combination with the vertical keel position of the climbing frame, lay out the line on the main structure 12 of the building to locate the installation position of the wall-mounted support; use a steel bar scanner to confirm the steel bar spacing in the main structure 12 of the building at the installation position, adjust the upper and lower positions of the wall-mounted support installation according to the steel bar spacing, and finally determine the drilling position of the main structure 12 of the building and make a mark; use a water drill to drill a φ50mm hole at the marked position, and use the through-wall screw 11 to install and fix the wall-mounted bracket 1 through the hole.

[0015] The adjustable supporting rod 4 of the wall-mounted support supports the climbing frame of the attached lifting scaffolding, which can bear the weight of the climbing frame and the load thereon, ensuring the stability of the entire system; the roller frame 2 and the roller 3 play a guiding role in the climbing frame, which helps to guide the movement direction of the climbing frame during the lifting process, avoid the climbing frame from deflecting or shaking, and can prevent the climbing frame from overturning during use, thereby ensuring the safety of construction operations; the anti-fall function of the climbing frame is achieved by the coordinated use of the star wheel and the pendulum needle. When the climbing frame body falls downward due to a fault, the anti-fall hook 6 is adjusted to a position where it can hook the climbing frame body, and the pendulum needle 8 is rotated so that the front end buckle is inserted into the wheel surface of the star wheel 7, thereby fixing the position of the anti-fall hook 6. The anti-fall hook 6 supports the climbing frame body to play an anti-fall role. This action is stable and reliable. When the climbing frame body falls, the anti-fall hook 6 is blocked by the star wheel 7 and the pendulum needle 8 and cannot be restored, thereby achieving anti-fall. The roller frame on the wall-mounted support is embedded in the vertical main keel guide rail of the climbing frame body. The guide rail transfers the load of the climbing frame body to the wall-mounted support through the adjustable support rod, and then transfers it to the main structure of the building.

[0016] Three wall-attached supports are set at each point of the attached lifting scaffold climbing frame, that is, it has three independent load-bearing, guiding, anti-tilting and anti-falling structures, which is far higher than the requirements of relevant safety regulations. In addition, the design and installation of this climbing frame support also take into account the firm connection with the building structure, that is, the wall-attached bracket is connected to the main structure of the building through the wall screw to ensure that the bearing requirements of support, anti-tilting and anti-falling can be met under various working conditions, and it is easy to disassemble and assemble, avoiding the defects of installing the wall-attached bracket with bolts implanted by anchor glue, providing necessary safety guarantees for the construction of high-rise buildings.
