Description

Technical Field

[0001] This invention relates to the field of elevator technology, and in particular to a method for assembling an elevator for a top formwork system. Background Technology

[0002] In high-rise building construction, construction hoists are indispensable vertical transportation tools. Currently, hoists are typically installed within pre-existing elevator shafts inside the building, and the guiding devices used with them are also standard elevator sections. These standard elevator sections need to be fixed to the wall. Therefore, the transport height of commonly used hoists is limited by the concrete structural layer, making it impossible to transport workers to the construction space above the structural layer. When performing top formwork construction above the structural layer, additional staircases are often required. However, moving back and forth on these staircases is time-consuming and laborious for construction workers, significantly reducing construction efficiency.

[0003] Patent 2011100328173 discloses a self-elevating construction elevator. The self-elevating construction elevator includes a car, an elevator power system located above the car, a steel wire rope connecting the car and the elevator power system, and an elevator guide device connected to the car. The elevator power system is placed in an elevator machine room, which is located above the structural construction floor and fixedly placed on a steel platform on the top of the high-rise building under construction. The elevator guide device includes a movable frame, connecting embedded parts, elevator guide rails, and guide rail supports. The upper part of the elevator guide rails is located within the movable frame, and the upper end of the elevator guide rails is located above the steel platform. The lower part of the elevator guide rails is located within the core tube elevator shaft.

[0004] While this device can increase the operating range of the construction elevator, each time the steel platform rises, the moving frame rises along with the elevator machine room and the steel platform. The elevator guide rails become disengaged between the lower part of the moving frame and the upper part of the guide rail supports. After the moving frame stops rising, the elevator guide rails at this point need to be rejoined according to the rising height. This is very troublesome during construction, and the suspended car is prone to slippage, posing a certain safety hazard. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a method for constructing a lifting platform for a top formwork system, which integrates the lifting platform with the top formwork structure, making its use more flexible and safer.

[0006] Therefore, the technical solution of the present invention is: a method for assembling a lifting platform for a top formwork system, wherein the lifting platform is installed after the top formwork platform is assembled, including the following steps:

[0011] S5. Correct the verticality of the standard section and lay out the line accordingly;

[0012] S6. Install and calibrate the guide rails on the standard section;

[0013] S7. Construct the elevator drive unit, cage unit, and counterweight balancing device;

[0019] Based on the above scheme and as a preferred embodiment of the above scheme: In step S1, a temporary step is provided on one side of the base support component and a retractable positioning pin is provided on the other side. The temporary step can be attached to the floor level, and the positioning pin can be inserted into the reserved hole to achieve pre-fixation of the base support component. At the same time, the base support component is a telescopic structure, and its length can be adjusted according to the installation environment so that the base support component can be fixedly connected to the wall.

[0020] Based on the above scheme and as a preferred option: in step S2, a Bailey support frame is provided on the top formwork platform, and the mounting beam at the bottom of the top machine room can be moved relative to the Bailey support frame to finely adjust the position of the top machine room.

[0021] Based on the above scheme and as a preferred embodiment of the above scheme: in step S3, the adjustable base includes two sliding grooves that are perpendicular to each other and slidably fitted. The first sliding groove is installed on the base support component, and the second sliding groove is connected to the bottom of the standard section, so as to adjust the verticality of the standard section.

The bottom support components are connected to the standard sections via electric hoists, allowing the elevator to climb along with the top formwork platform. The bottom support components are fixed to the concrete floor surface, eliminating the need for the support frame to be built from the bottom of the building, which greatly reduces the amount of standard sections used and lowers construction costs. At the same time, the bottom support components can further ensure the safety of the cage operation and reduce safety hazards.

[0031] 2. The base support component is designed as a telescopic structure, which can be used in different installation environments.
