Description

Technical Field

[0001] The present invention relates to the technical field of lifting platforms, and in particular to a convenient wall attachment method and a fall prevention method for a lifting platform support system. Background Art

[0002] The core of super high-rise building construction lies in the jacking platform system used in the core tube construction. The key to the jacking platform system lies in the support system. The overall jacking steel platform support principle mainly adopts two forms. One is the traditional low-position jacking technology, cylinder cross support column and climbing upper and lower box beam trusses. The other is the micro-convex fulcrum as its attachment method. The support frame is like a "climbing claw" climbing on a special template.

[0003] Traditional low-position jacking transmits force to the supporting box beam through the supporting column, and then to the core tube shear wall. It is necessary to open a large hole in the main structure of the shear wall as the supporting point of the supporting box beam, which greatly weakens the main structure and is difficult to repair later;

[0004] The slightly convex support point is used for climbing, and the concrete bracket is reserved on the wall, and then a special formwork is attached. The upper and lower supports are equipped with 6 "climbing claws" that are hooked in the reserved groove of the special formwork. They can withstand large loads. In case of emergencies, the "climbing claws" can be attached and stuck nearby, and the lifting attachment and anti-falling effects are safe and reliable. However, the support frame is difficult to make, the special formwork and lifting bracket are expensive, there are many support points, and more concrete needs to be poured. Summary of the invention

[0005] The object of the present invention is to provide a convenient wall attachment method and a fall prevention method for a jacking platform support system, so as to solve the problems raised in the above-mentioned background technology.

[0007] Preferably, the box-type support platform is in a circular ring structure, and two box-type support platforms are provided, and the two box-type support platforms are symmetrically distributed up and down with respect to the upper support frame.

[0008] Preferably, the upper support frame and the lower support frame are both in a square frame structure, a through opening is provided on the top plate of the lower support frame, and the long-stroke oil cylinder and the long-stroke oil cylinder cavity both pass through the through opening.

[0009] Preferably, the shoe-shaped steel corbels are provided in two groups, the two groups of shoe-shaped steel corbels are distributed in two vertical rows, and the outer cover frame is a square frame structure.

[0010] Preferably, two limit frames are provided, the anti-falling plate is located between the two limit frames, a plurality of anti-falling teeth are provided, and the plurality of anti-falling teeth are arranged vertically along the outer coat frame.

[0011] A convenient wall attachment method for a jacking platform support system includes the following steps:

[0012] Step 1: In the initial state, the boot-shaped steel brackets on the upper support frame and the lower support frame are both extended into the slots on the wall surface;

[0013] Step 2: Lift the upper support frame, start the long-stroke oil cylinder, and the upper support frame and the outer frame are lifted to the next construction layer by the thrust of the long-stroke oil cylinder, and the boot-shaped steel bracket on the surface of the upper support frame is inserted into the groove on the surface of the next construction layer. During this process, the boot-shaped steel bracket swings backward around the rotating support shaft and fits the wall. After the upper support frame climbs into place, the boot-shaped steel bracket swings forward into the groove to fix the upper support frame;

[0014] Step 3: Return the cylinder, the lower support frame follows the outer cavity of the large-stroke cylinder to rise to the position of the original upper support frame, and the boot-shaped steel bracket on the surface of the lower support frame is inserted into the slot to fix the lower support frame and complete the jacking.

[0015] A method for preventing a jacking platform support system from falling, characterized in that the method for preventing a jacking platform support system from falling comprises the following steps:

[0016] Step 1: Structural composition. The support system of the present invention is composed of platform pillars, elastic supports, upper support frames, lower support frames, long-stroke cylinders, outer frame, boot-shaped steel brackets, etc. The main materials are Q345C material H-shaped steel, 10mm / 20mm thick steel plate, elastic supports, Ф900×25 round steel pipes, rubber pads, long-stroke cylinders, etc.

[0017] Step 2: Pre-treatment of the support frame. The upper and lower support frames are welded with Q345C, H-shaped steel and steel plates to ensure overall rigidity. Three rows of upper and lower steel bull legs are set on the left side, with a total of six boot-shaped steel bull legs. The lower support frame needs to reserve holes according to the size of the outer steel cavity of the large-stroke cylinder, and a counterweight is added to the upper right part to prevent falling. Patterned steel plates are added to the bottom of the upper and lower support frames, which can be used as operating platforms for easy maintenance;

[0018] Step 3: Pre-treatment of climbing components. The boot-shaped steel corbel is in a "boot-shaped" shape and can be inserted into the slot on the wall surface. A steel pin is set on the upper part as a rotating support shaft, a reinforcing plate is set on the upper part, and a counterweight is set behind the corbel. As the upper support frame is lifted, the boot head of the boot-shaped steel corbel can be turned out of the slot on the wall surface and lifted against the wall. After lifting to the reserved square hole of the next layer, the boot-shaped steel corbel can be swung back to the slot using the counterweight. After the upper support frame is lifted, the return cylinder with a large stroke follows the large stroke cylinder cavity to rise. The principle is the same as that of the upper support frame. In order to prevent the boot-shaped steel corbel from swinging forward, a steel plate is added in front of the boot-shaped steel corbel.

[0019] Step 4: Anti-fall measures. Anti-fall measures are set on the upper right side of the lower support frame to emergency withstand the fall of the outer frame caused by the failure of the long-stroke cylinder. A thick steel plate is used to make an anti-fall plate. The anti-fall plate is connected to the pin shaft of the lower support frame ear plate through a limit frame on each side. A rubber pad is set at the bottom of the anti-fall plate to slow down the fall of the anti-fall plate. As the lower support frame is lifted, the anti-fall plate can rotate about 0-60° around the pin shaft. If the long-stroke cylinder fails and the outer frame falls, the anti-fall plate can jam the anti-fall teeth on the surface of the outer frame to prevent the upper support structure from falling.

[0020] Compared with the prior art, the invention has the following advantages:

[0021] 1. The present invention proposes a simple jacking and attaching corbel, which uses a counterweight to simplify the jacking process, eliminates the need for a small push-pull oil cylinder, simplifies anti-falling measures, forms a new type of jacking and wall attachment method, reduces the hole in the wall, does not affect the penetration of the stressed steel bars, and is very convenient for later repair;

[0022] 2. The climbing support bracket of the present invention is directly attached to the wall, eliminating the need for a special attachment template; each support frame uses a large-stroke oil cylinder, eliminating the need for a small-stroke oil cylinder for a push-pull support frame;

[0023] 3. The present invention adds a patterned steel plate at the bottom of the support frame, which can be used as an operating platform for easy maintenance. BRIEF DESCRIPTION OF THE DRAWINGS
