Description

Technical Field

[0001] This invention belongs to the field of building core tube construction, and specifically relates to an integrated platform and construction method with a single machine position on one side and a double machine position on the other side, and a built-in tower crane. Background Technology

[0002] Hydraulic climbing formwork, as an integrated platform, is used for the construction of core tubes in high-rise and super high-rise buildings. It is a relatively mature technology. The structure mainly includes wall anchors, guide rails, a main frame, an upper frame, and hanging brackets. The main frame is equipped with climbing boxes that cooperate with the guide rails. The guide rails have ladders. The climbing boxes, in conjunction with the ladders, allow the climbing formwork to ascend while the guide rails remain stationary. Even when the climbing boxes are fixed to the wall anchors, they still cooperate with the ladders to lift the guide rails, thus alternately enabling the hydraulic climbing formwork to construct the core tube. During core tube construction, multiple hydraulic climbing formwork units are connected end-to-end to surround the core tube for pouring and casting.

[0003] Tower cranes are needed for concrete delivery during pouring. In core tube construction, setting up tower cranes inside the core tube can effectively improve coverage and construction efficiency. Therefore, the practice of setting up tower cranes inside the core tube has gradually emerged. For larger core tubes, integrated platforms can meet the requirements of stability and ensure construction safety. However, there are often situations where the space is relatively small. After setting up tower cranes, only three rows of hydraulic integrated platforms can be arranged in this space. One side of the tower crane is a single machine position, and the other side is a double machine position. The connection between the double machine positions on one side is relatively stable, but the structural stability of the integrated platform on the single machine position side is poor, which poses a technical problem of construction safety hazards. Summary of the Invention

[0004] This invention provides an integrated platform and construction method with a single-unit station on one side and a double-unit station on the other, and a built-in tower crane. This addresses the technical problem that while the integrated platform can ensure stability and construction safety for large-sized core tubes, there are often situations where space is limited. In such cases, after arranging the tower crane, only three rows of hydraulic integrated platforms can be arranged, with one side of the tower crane being a single-unit station and the other side being a double-unit station. The connection between the double-unit stations on one side is relatively stable, but the structural stability of the integrated platform on the single-unit station side is poor, posing a potential construction safety hazard.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an integrated platform with a single-unit location on one side and a double-unit location on the other, and a built-in tower crane, is installed inside the core tube. The tower crane is arranged in a conventional manner, which will not be elaborated here. The integrated platform includes a single-unit integrated platform located on one side of the tower crane inside the core tube and a double-unit integrated platform located on the other side. The single-unit and double-unit integrated platforms have the same structure. The single-unit integrated platform includes a wall-mounted device, guide rails, lifting components, a main truss, a hanging frame, and an upper frame. The upper frame includes a continuous upper frame upright and top-level crossbeams, first-level crossbeams, and second-level crossbeams installed between the upper frame uprights. A connecting beam group is used to connect the single-unit integrated platform and the dual-unit integrated platform. A reinforcing beam is also used to connect the single-unit integrated platform and the dual-unit integrated platform. The reinforcing beam is set on the side of the upper frame upright closest to the wall-mounted device and is fixedly connected to the upper frame upright by bolts. There are four reinforcing beams in the height direction. The four reinforcing beams include reinforcing beam one located below and close to the top horizontal beam, reinforcing beam two located below and close to the first-floor horizontal beam of the upper frame, reinforcing beam three located at the top height of the second-floor horizontal beam of the upper frame, and reinforcing beam four located at the top of the bottom horizontal beam of the main truss.

The first and second layer crossbeams of the single-station integrated platform are square structures formed by butt welding of channel steel, with back-to-back channel steel welded on both sides. The connecting beam group is fixed and installed by U-bolts that pass through the back-to-back channel steel on both sides of the channel steel in the first layer crossbeam of the single-station integrated platform. The bottom crossbeam of the main truss of the dual-station integrated platform is a single channel steel, and the connecting beam group is fixed and installed by U-bolts that pass through the single channel steel. The bottom crossbeam of the main truss (24) of the single-unit integrated platform is a square structure with butt welded channel steel and back-to-back channel steel welded on both sides. The connecting beam group is fixed by two U-bolts that pass through the back-to-back channel steel respectively. The hanging column of the double-unit integrated platform is a single channel steel and is fixed to the bottom crossbeam of the main truss of the double-unit integrated platform by bolts. The hanging column of the single-unit integrated platform is two columns that are respectively connected to the two sides of the square structure with butt welded channel steel by bolts. The hanging column of the double-unit integrated platform is a single channel steel and is fixed to the hanging column by bolts. The hanging column of the single-unit integrated platform has the same structure as the first-layer crossbeam of the single-unit integrated platform.

[0011] Preferably, the single-position integrated platform and the dual-position integrated platform are also provided with short beam groups.

[0012] Preferably, a platform slab is laid on top of the connecting beam group and the short beam group.

[0013] Preferably, two connecting beams are provided on the top-level crossbeam, the first-level crossbeam, the top crossbeam of the main truss, and the hanging beam, and one connecting beam is provided at the top of the second-level crossbeam and the bottom crossbeam of the main truss. The connecting beams are I-beams or channel steel.

[0014] The construction method for an integrated platform with a single-machine station on one side and a double-machine station on the other, and a built-in tower crane, includes the following steps: S1. After the tower crane is installed in place, install the wall-mounted devices and guide rails for single-position and double-position cranes, and then install the main truss and lifting components. S2. Connect the continuous, integral upper frame uprights and crossbeams together, arrange stable channel steel, and then hoist and install the whole structure onto the main truss. S3. Install hangers on the main truss; S4. Install connecting beams and reinforcing beams. Set one connecting beam and one reinforcing beam at the top of the second-floor crossbeam and the bottom crossbeam of the main truss. Set two connecting beams on the top-floor crossbeam, the first-floor crossbeam, the top crossbeam of the main truss, and the hanging beam crossbeam. Set a reinforcing beam below and near the top-floor crossbeam, and set a reinforcing beam below and near the first-floor crossbeam of the upper frame. Other conventional structures not mentioned in the process are also installed, such as the four-sided formwork and auxiliary components. The erection and operation of the formwork is a mature and well-known technology in the climbing formwork industry, and its detailed structure and principle will not be described in detail here.

[0015] S5. Install short beam assemblies, which are located at the top of the top beam, the first-floor beam, the second-floor beam, the top beam of the main truss, the bottom beam of the main truss, and the top of the hanging beam. S6. A platform slab is laid on top of the connecting beam group and the short beam group. A guardrail is installed on the platform slab for protection. This structure is conventional and will not be described in detail here.

[0016] The beneficial effects of this invention are as follows: This invention addresses the situation where, when the core tube is relatively small, only three rows of hydraulic integrated platforms can be installed in the space after arranging tower cranes, with one side of the tower crane serving as a single-position and the other side as a double-position construction site. 1. In addition to the connecting beam group between the single-station integrated platform and the dual-station integrated platform, a reinforcing beam was added to improve the overall integrity of the single-station integrated platform and the dual-station integrated platform. 2. The upper frame uprights and stabilizing channel steel form an L-shaped groove, and the reinforcing beam is fitted and embedded in the L-shaped groove and cannot move, thus ensuring stability; 3. Based on the existing single connecting beam, two connecting beams are installed at the same height where there is no reinforcing beam, and a single connecting beam is maintained at the same height where there is a reinforcing beam. 4. The first and second layer beams of the upper frame of the single-unit integrated platform were redesigned, laid out, and reinforced. The structure was strengthened and widened, which enhanced the support effect on the connecting beam group and the short beam group, and ensured the strength and stability of the single-unit side of its own structure. 5. Double hangers are used for the single-unit mounting bracket, and the crossbeams of the mounting bracket are also reinforced to increase the structural strength and stability of the bottom of the single-unit integrated platform.

[0017] This application, combining improvements 1, 2, 3, 4, and 5, can form a whole with high structural stability and sufficient safety performance. This eliminates the need to externally mount the tower crane for safety reasons in situations where the core tube houses the tower crane and only three rows of hydraulic integrated platforms can be arranged. It retains the construction efficiency of an internal tower crane while ensuring construction safety. It also solves the problem of limited space, where only three rows of hydraulic integrated platforms can be arranged after the tower crane is installed, with one side of the tower crane being a single-position platform and the other side a double-position platform. While the connection between the double-position platforms on one side is relatively stable, the structural stability of the integrated platform on the single-position side is poor, posing a technical risk to construction safety.
