Description

Technical Field

[0001] The present invention relates to the technical field of subway station construction, and in particular to a hanger system suitable for installing a roof plate of an assembled station and a method of using the hanger system. Background Art

[0002] At present, during the assembly process of fully prefabricated subway stations, due to the influence of the first concrete support, some top plate components cannot be installed in place through the door crane. It is necessary to install steel supports in advance and then cut off the concrete supports. After the system conversion is completed, the top plate components below the concrete supports are installed. However, this approach has the following risks and shortcomings: 1. The concrete support and the surrounding structure form a rigid body. After being converted into steel supports, it can only withstand pressure but not tension. The integrity of the support structure system is poor and the support system is prone to deformation; 2. The efficiency of cutting off the concrete support is slow, which affects the overall assembly progress and prolongs the assembly period; 3. When the top plate is not assembled, there is an open surface 10 meters above the cut concrete support, and the cutting operation has a great safety risk.

[0003] Among the above technical issues: Technical Issue 1: directly affects construction safety and feasibility, and the conversion of the support system is likely to cause the conversion of the internal force mechanism of the support system; Technical Issue 2: directly affects the construction progress, and the long-term concrete support cutting operation will lead to a decrease in assembly efficiency and affect the construction period cost; Technical Issue 3: There are safety hazards, and the cutting of concrete supports requires the arrangement and installation of a rope saw on the top plate of the previous ring, which is a high-altitude edge operation.

[0004] For example, patent CN113200459A discloses a sling with adjustable stress state for installing the roof of an assembled subway station. The roof is composed of two prefabricated left and right roof components. At least four lifting points are distributed along the span direction of the roof, including two proximal lifting points and two distal lifting points. The sling is a hoisting trolley running on the crane main beam track. The trolley wire rope is wound on the trolley winch and is retracted and extended as the trolley winch rotates. The sling also includes hooks arranged on a horizontal beam, and the hooks are connected one by one to the lifting points of the roof through wire ropes. If this sling is used, the concrete support will affect the operation and the concrete support needs to be removed, which affects construction efficiency and poses a safety risk. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the present invention provides a hoisting system suitable for the installation of prefabricated station roofs and a method of using the system, which can efficiently complete the station roof hoisting operation without removing the concrete support.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0016] The sling component is welded together using section steel, and comprises a top plate, a bottom plate and a connecting vertical plate. The ends of the top plate and the bottom plate on the same side are welded together via the connecting vertical plate.

[0017] The steel wire rope sling connecting the gusset plate and the top of the sling component is composed of two steel wire ropes.

[0018] A method for using the spreader system suitable for installing a prefabricated station roof comprises the following steps:

[0019] S1. Place a set of sling components on the ground under the prefabricated roof, lift the gantry crane, and use the sling wire rope to connect it to the upper rotary bearing and rotary connector.

[0033] Preferably, the sling component is a "C"-shaped sling; the rotating connector can also be a powered connector; the lower part of the rotating bearing is connected to a steel beam, and a group of connecting plates are provided at the lower part of the steel beam. A "C"-shaped sling is hoisted under each connecting plate by a wire rope, and the top plate is hoisted stably and reliably by a group of "C"-shaped slings.

[0034] The wire rope sling connecting the gusset plate and the top of the spreader assembly utilizes a two-wire rope assembly. The lower end of the wire rope is connected to an upper lifting lug located at the top of the spreader assembly. This simple, stable, and reliable structure is achieved. The specifications and lengths of the two wire ropes are determined by the combined weight of the top plate and C-shaped spreader assembly.

[0035] Furthermore, the "C"-shaped sling adopts a welded combination of steel sections. The sling components include a top plate, a bottom plate and a connecting vertical plate. The ends of the top plate and the bottom plate on the same side are welded together by a connecting vertical plate, and its size can be adjusted according to the weight of the top plate to ensure that the "C"-shaped sling has sufficient load-bearing capacity and rigidity.

[0036] A positioning structure for positioning the top plate is provided within the cavity of the spreader component. Preferably, the positioning structure comprises a connected shackle, a top plate component wire rope positioning rigging, and a top plate lifting lug, the top plate lifting lug being located on the inner wall of the spreader component cavity. The top plate component wire rope positioning rigging utilizes a single steel wire rope, which is combined with a lifting nail. Its specifications and length are determined by the internal space of the "C"-shaped spreader cavity.

[0037] The present invention includes a "C"-shaped sling combination, upper and lower rigging, and a rotating device. The "C"-shaped sling has a steel structure, and its internal C-shaped cavity should have the space to encompass the concrete support and the top plate. The upper and lower rigging include an upper rigging and a lower rigging, wherein the upper rigging has the function of connecting the "C"-shaped sling to realize the connection between the "C"-shaped sling and the rotating device, and the lower rigging has the function of connecting the top plate component to realize the connection between the "C"-shaped sling and the top plate; the rotating structure can rotate the entire "C"-shaped sling combination 360° to ensure the consistent movement of the combined sling. The entire device system can meet the requirements of accurate and rapid installation of the top plate under the concrete support without dismantling the concrete support.

[0038] Preferred embodiments of the present invention are:
