Abstract

The present invention discloses a method for constructing a suspended elevator shaft, comprising the following steps: 1. constructing a suspension skeleton; 2. constructing an elevator shaft bottom plate; 3. constructing a third layer of prefabricated wall panels; 4. constructing a second layer of prefabricated wall panels; 5. constructing a first layer of prefabricated wall panels; 6. pre-embedding a suspension skeleton deformation monitor; and 7. waterproofing and anti-seepage treatment. The present invention provides an installation foundation for the prefabricated wall panels of the suspended elevator shaft by adopting a simulated construction method from top to bottom, avoiding the need to lay a supporting foundation layer in the basement elevator drop plate, and then assembling the prefabricated wall panels in sequence from bottom to top. The construction is orderly, eliminating the need for the construction process of removing the supporting foundation layer in a narrow space at a later stage, ensuring that the shaft of the seismic isolation elevator shaft and the basement elevator drop plate are disconnected at the lower part of the seismic isolation layer. At the same time, a suspension skeleton deformation monitor is pre-embedded on the suspension skeleton to monitor the real-time data of whether the suspension skeleton is deformed, and monitor the safe operation status of the suspended elevator shaft.

Description

Technical Field

[0001] This invention belongs to the field of suspended elevator shaft construction technology, and specifically relates to a method for constructing a suspended elevator shaft. Background Technology

[0002] Seismic isolation structures are widely used in many buildings, such as elevators. Elevator shafts are the channels through which elevators are installed, and their dimensions are determined by the elevator model. Existing seismic isolation elevator shafts effectively assist in elevator installation and use, and can also filter out frequencies in the incoming seismic waves that resonate with the structure, thus providing excellent seismic wave shielding. The seismic isolation elevator shaft needs to be disconnected from the basement elevator slab below the isolation layer, and then connected to the upper structure of the isolation layer to form a suspended elevator shaft. However, the small distance between the suspended elevator shaft and the basement elevator slab results in insufficient operating space for construction workers, and makes the later dismantling of the bottom and side supports difficult. Summary of the Invention

[0003] The technical problem to be solved by this invention is to address the shortcomings of the prior art by providing a method for constructing suspended elevator shafts. This method utilizes a simulated suspended frame from top to bottom, providing an installation foundation for the precast wall panels of the suspended elevator shaft. This avoids laying a support foundation layer inside the basement elevator slab. The precast wall panels are then assembled sequentially from bottom to top, ensuring orderly construction and eliminating the need for later removal of the support foundation layer in confined spaces. This ensures the shaft of the seismic isolation elevator shaft is disconnected from the basement elevator slab below the seismic isolation layer. Simultaneously, a deformation monitor is embedded in the suspended frame to monitor real-time deformation data, thus monitoring the safe operation of the suspended elevator shaft and facilitating widespread use.

[0011] Step 106: Use the third-layer supporting steel beam to connect the bottom of the third-layer suspension frame to form a suspension frame, which extends into the basement elevator lowering slab.

[0051] like Figures 1 to 8 As shown, a method for constructing a suspended elevator shaft according to the present invention includes the following steps:

[0052] Step 1: Constructing the suspended frame, the process is as follows:

[0053] Step 101: Install elevator shaft suspension frame embedded parts in the seismic isolation layer 1, and fix the first layer suspension frame 4 to the elevator shaft suspension frame embedded parts.

[0054] Step 102: Connect the bottom of the first layer suspension frame 4 with the first layer support steel beam 5 rings;

[0055] Step 103: Fix the second layer suspension frame 6 to the bottom of the first layer support steel beam 5;

[0056] Step 104: Connect the bottom of the second-layer suspension frame 6 using the 7 rings of the second-layer support steel beam;

[0057] Step 105: Fix the third layer suspension frame 8 to the bottom of the second layer support steel beam 7;

[0058] Step 106: Use the third layer support steel beam 9 rings to connect the bottom of the third layer suspension frame 8 to form a suspension frame, which extends into the basement elevator drop plate 3;

[0059] Step 2, Construction of elevator shaft bottom plate: The elevator shaft bottom plate 10 is hoisted from the shaft hole 2 into the suspension frame and installed on the third-floor support steel beam 9;

[0060] Step 3: Construct the third layer of precast wall panels: hoist the third layer of precast wall panels into the suspension frame through well hole 2 and install them on the third layer suspension frame 8;

[0061] Step 4: Construct the second layer of precast wall panels: hoist the second layer of precast wall panels 15 from the well hole 2 into the suspension frame and install them on the second layer of suspension frame 6;

[0062] Step 5: Construct the first layer of precast wall panels: hoist the first layer of precast wall panels 16 from the well hole 2 into the suspension frame and install them on the first layer of suspension frame 4;

[0063] Step 6: Pre-embed the deformation monitoring device for the suspension frame;

[0064] Step 7: Waterproofing and seepage prevention treatment: Apply waterproofing and seepage prevention treatment to all joints.

[0065] It should be noted that by adopting a simulated construction suspension frame from top to bottom, an installation foundation is provided for the prefabricated wall panels of the suspended elevator shaft. This avoids laying a support foundation layer inside the elevator drop slab in the basement. Then, by assembling the prefabricated wall panels from bottom to top, the construction is orderly and eliminates the construction process of removing the support foundation layer in a confined space later. This ensures that the shaft of the seismic isolation elevator shaft is disconnected from the elevator drop slab in the basement at the bottom of the seismic isolation layer. At the same time, a suspension frame deformation monitor is embedded in the suspension frame to monitor the real-time data of whether the suspension frame is deformed and to monitor the safe operation status of the suspended elevator shaft.

[0068] It should be noted that the number of T-shaped steel strips 18 to be set between two adjacent vertical angle steels 17 along the circumferential direction can be selected according to the size of the elevator shaft and the support strength, which has strong scalability.

[0069] In this embodiment, the third layer precast wall panel, the second layer precast wall panel 15 and the first layer precast wall panel 16 each include two left side wall precast panels 11, two right side wall precast panels 12, one front side wall precast panel and one rear side wall precast panel.
