Description

Technical Field

[0001] This invention belongs to the field of building engineering technology, specifically relating to a modular steel structure building complex that can be quickly installed and its installation method. Background Technology

[0002] In the construction of steel structure buildings, on-site welding is frequently employed. First, pile driving must be carried out during the main structure construction, followed by the erection of the main columns. After the main frame structure is completed, the construction of internal compartments, water and electricity pipelines, and interior decoration proceed. Each step of construction must be carried out based on the previous process, resulting in a long construction period and low efficiency. Column installation requires cranes to suspend the columns in the air and connect them to the foundation, which is difficult, time-consuming, and highly dangerous. The installation of horizontal steel structures also requires cranes to suspend the horizontal structures in the air, with workers welding on-site. This is difficult, time-consuming, and highly dangerous. Furthermore, the on-site construction environment is harsh, with extensive on-site welding work, making it difficult to guarantee construction quality and posing high safety risks to workers.

[0003] Therefore, there is a need for a steel structure building and its installation method that can be carried out without relying on on-site construction, allows multiple processes to be carried out simultaneously, can make great use of factory modular prefabrication, and has low on-site operation difficulty, short high-altitude hoisting time, and fewer processes. Summary of the Invention

[0004] The technical problem to be solved by this invention is to address the shortcomings of the existing technology by providing a modular steel structure building complex that can be installed quickly and its installation method. This method enables simultaneous implementation of the main frame, foundation, and cabin modules at each stage, allowing for rapid on-site installation. It solves the problems of long hoisting time, high risk, low prefabrication degree, long operation time, and harsh environment in the manufacturing and installation of various types of steel structures. This comprehensively shortens the on-site operation period, improves the degree of modular prefabrication, enhances construction quality, reduces construction difficulty, reduces high-altitude operations, and shortens the time workers spend on-site and at heights.

[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows:

[0006] A modular steel structure building complex capable of rapid installation includes several steel frame units and several rotating support bases adapted to the number of steel frame units. Each steel frame unit includes several opposing rotating side columns and supporting side columns. A rotating component is installed at the bottom of each rotating side column, and a horizontal compartment support beam is provided between the rotating side columns and the supporting side columns. Each rotating support base includes a base, a rotating shaft, and a pre-embedded structure. The rotating shaft is installed on the upper part of the base and is adapted to the rotating component for installing the steel frame units. The steel frame units can rotate around the rotating shaft to achieve conversion between horizontal and vertical states. The pre-embedded structure is installed at the lower part of the base to ensure the stability of the overall structure by being buried in the ground. The rotating side columns and supporting side columns of adjacent steel frame units are connected by a quick-connect fixing device to form the main frame.

[0007] The modular steel structure building complex also includes several cabin modules and traction pulley assemblies. The cabin modules can move vertically along the columns of the steel structure frame unit and horizontally along the cabin support beams under the drive of the traction pulley assemblies.

[0008] In the above scheme, adjacent rotating side columns are connected by rotating side horizontal columns, adjacent supporting side columns are connected by supporting side horizontal columns, and the rotating side columns and supporting side columns that are arranged opposite to each other are connected by a central horizontal column; the cabin support beam is installed between the oppositely arranged rotating side horizontal columns and supporting side horizontal columns, and the cabin support beam is arranged parallel to the central horizontal column.

[0009] In the above scheme, the rotation shaft of the rotating support base is installed on one side of the upper part of the base, and the other side of the upper part of the base is reserved for the installation space of the support side column.

[0010] In the above scheme, the quick connection fixing device adopts the form of bolts and nuts, welding, or clamps.

[0011] In the above scheme, the cabin module includes a cabin body and a sliding member. The sliding member is installed at the bottom of the cabin body and is adapted to the cabin support beam, and can move along the cabin support beam.

[0012] In the above scheme, the modular steel structure building complex also includes a movable support platform, which is installed on the columns of the steel structure frame unit and can move vertically under the drive of the traction pulley assembly; the cabin module can be temporarily placed on the movable support platform.

[0013] In the above scheme, the modular steel structure building complex also includes a movable fixed pulley group. The movable fixed pulley group is installed on the column of the steel structure frame unit and located on the opposite side of the movable bearing platform. The movable fixed pulley group can move vertically under the drive of the traction pulley assembly.

[0014] In the above scheme, the traction pulley assembly includes a drive mechanism, a first traction rope, a second traction rope, and a third traction rope; one end of the first traction rope is connected to the drive mechanism, and the other end passes through several fixed pulleys and is connected to the movable support platform; one end of the second traction rope is connected to the drive mechanism, and the other end passes through several fixed pulleys and is connected to the fixed pulley group; one end of the third traction rope is connected to the drive mechanism, and the other end passes through the movable fixed pulley group and is connected to the cabin module.

[0015] In the above scheme, the driving mechanism adopts a horizontal winch, and the winch is equipped with a drum that matches the number of traction ropes.

[0016] Accordingly, the present invention also proposes an installation method for the aforementioned modular steel structure building complex that can be quickly installed, comprising the following steps:

[0017] S1. Several steel structure frame units are prefabricated in the steel structure factory, several rotating support bases are prefabricated on the installation site, and the cabin modules are prefabricated in other factories simultaneously.

[0018] S2. Transport several steel frame units to the construction site. First, install a single steel frame unit. Place the steel frame unit horizontally and assemble its rotating parts with the rotating shaft of the rotating support base. Pull the steel frame unit with the traction pulley assembly to rotate the steel frame unit around the rotating shaft until it is vertical. At this time, the support column of the steel frame unit rotates to the adjacent rotating support base. Thus, the installation of one steel frame unit is completed.

[0019] S3. Following the method in step S2, install the other steel structure frame units in sequence, and connect adjacent steel structure frame units to form the main frame through quick connection fixing devices.

[0020] S4. Install a movable support platform on a column on one side of the main frame, and extend a first traction rope from the drive mechanism of the traction pulley assembly to connect with the movable support platform, and place the cabin module on the movable support platform; install a movable fixed pulley group on a column on the other side of the main frame, and extend a second traction rope from the drive mechanism of the traction pulley assembly to connect with the cabin module after passing through the movable fixed pulley group.

[0021] S5. Start the drive mechanism to raise the movable support platform and the movable fixed pulley group to a suitable height, and then pull the cabin module into the set position of the main frame.

[0022] The beneficial effects of this invention are as follows:

[0023] 1. The steel structure frame unit, rotating support base, and cabin module of the present invention can be prefabricated in different sites, and multiple processes can be carried out simultaneously. The prefabricated components can be transported to the construction site for rapid installation, which greatly shortens the on-site operation period. At the same time, it can adopt modular prefabrication in the factory to a great extent, which reduces the difficulty of on-site construction and improves the construction quality.

[0024] 2. The installation of the steel structure frame units requires no hoisting; simply rotate them from a horizontal to a vertical position using the traction pulley assembly around the rotating support base. Similarly, the installation of the compartment modules also requires no hoisting; simply pull them into their designated positions within the steel structure frame using the traction pulley assembly. This installation method reduces high-altitude work, shortens on-site and high-altitude work time, significantly improves construction safety, and also reduces construction costs.

[0025] 3. This invention is applicable to steel structure buildings of different sizes, with less welding work on the construction site, less environmental pollution, and less noise.

[0026] 4. The cabin modules of this invention are prefabricated in the factory. Electrical equipment, cables, pipelines and other components are pre-installed in the cabin modules. On-site, only the interfaces between the cabins need to be connected before they can be put into use, which greatly reduces the interior construction time.

[0027] 5. The main frame of this invention is manufactured in a workshop with a good welding and testing environment. Compared with open-air construction, the welding quality of the column structure is high, and 100% non-destructive testing can be achieved. Attached Figure Description

[0044] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0045] like Figure 1-7 As shown, a modular steel structure building complex that can be quickly installed according to an embodiment of the present invention includes several steel structure frame units 10 and several rotating support bases 20 adapted to the number of steel structure frame units 10; the modular steel structure building complex also includes several cabin modules 40, traction pulley assemblies 70, movable bearing platforms 50 and movable fixed pulley groups 60.

[0046] See Figure 2-5The steel structure frame unit 10 includes several opposing rotating side columns 11 and supporting side columns 12. A rotating component 16 is installed at the bottom of each rotating side column 11. Adjacent rotating side columns 11 are connected by rotating side horizontal columns 13, and adjacent supporting side columns 12 are connected by supporting side horizontal columns 14. The opposing rotating side columns 11 and supporting side columns 12 are connected by a central horizontal column 15. A compartment support beam 17 is installed between the opposing rotating side horizontal columns 13 and supporting side horizontal columns 14, and the compartment support beam 17 is parallel to the central horizontal column 15. The rotating side columns 11 and supporting side columns 12 of adjacent steel structure frame units 10 are quickly and stably connected by a quick-connect fixing device 30 to form the main frame.

[0047] See Figure 6 The rotating support base 20 includes a base 21, a rotating shaft 22, and a pre-embedded structure 23. The rotating shaft 22 is installed on the upper part of the base 21 and is adapted to the rotating component 16 for installing the steel structure frame unit 10. The steel structure frame unit 10 can rotate around the rotating shaft 22 to realize the conversion between horizontal and vertical states. The pre-embedded structure 23 is installed on the lower part of the base 21 and is buried in the ground to ensure the stability of the overall structure.

[0048] See Figure 7 The compartment module 40 can move vertically along the columns of the steel structure frame unit 10 and horizontally along the compartment support beam 17, driven by the traction pulley assembly 70. Specifically, the compartment module 40 includes a compartment body 41 and a sliding member 42. The sliding member 42 is installed at the bottom of the compartment body 41 and is adapted to the compartment support beam 17, allowing it to move along the compartment support beam 17.

[0049] The movable support platform 50 is installed on the columns of the steel structure frame unit 10 and can move vertically under the drive of the traction pulley assembly 70; the cabin module 40 can be temporarily placed on the movable support platform 50. The movable fixed pulley assembly 60 is installed on the columns of the steel structure frame unit 10 and located on the opposite side of the movable support platform 50. The movable fixed pulley assembly 60 can move vertically under the drive of the traction pulley assembly 70 and is fixed in a designated position. The traction pulley assembly 70 includes a drive mechanism 71, a first traction rope 72, a second traction rope 73, and a third traction rope 74. One end of the first traction rope 72 is connected to the drive mechanism 71, and the other end passes over several fixed pulleys 75 and is connected to the movable support platform 50. One end of the second traction rope 73 is connected to the drive mechanism 71, and the other end passes over several fixed pulleys 75 and is connected to the fixed pulley group. One end of the third traction rope 74 is connected to the drive mechanism 71, and the other end passes over the movable fixed pulley group 60 and is connected to the cabin module 40.

[0050] Further optimization involves installing the rotation shaft 22 of the rotating support base 20 on one side of the upper part of the base 21, and reserving installation space for the support side column 12 on the other side of the upper part of the base 21, so that the steel structure frame unit 10 can remain flat as a whole when installed on the rotating support base 20.

[0051] Further optimization involves the use of a bearing adapted to the rotating shaft 22 of the rotating support base 20 for the rotating component 16 at the bottom of the rotating side column 11. The bearing and the rotating shaft 22 cooperate with each other and have a certain load-bearing capacity.

[0052] Further optimization is achieved by using bolts and nuts, welding, or clamps for the quick-connect fixing device 30.

[0053] Further optimization involves adopting a horizontal winch for the drive mechanism 71. The winch is equipped with a drum that matches the number of traction ropes and needs to have certain traction force, speed adjustment function, and forward and reverse rotation function.

[0054] Accordingly, the present invention also proposes an installation method for the aforementioned modular steel structure building complex that can be quickly installed, comprising the following steps:

[0055] S1. Several steel structure frame units 10 are prefabricated in the steel structure factory, several rotating support bases 20 are prefabricated on the installation site, and the cabin modules 40 are prefabricated in other factories at the same time.

[0056] S2. Transport several steel structure frame units 10 to the construction site and install a single steel structure frame unit 10 first: Place the steel structure frame unit 10 horizontally and assemble its rotating part 16 with the rotating shaft 22 of the rotating support base 20; pull the steel structure frame unit 10 through the traction pulley assembly 70, causing the steel structure frame unit 10 to rotate around the rotating shaft 22 until it is in a vertical position. At this time, the support column 12 of the steel structure frame unit 10 rotates to the adjacent rotating support base 20; thus, the installation of one steel structure frame unit 10 is completed.

[0057] S3. Following the method in step S2, install the other steel structure frame units 10 in sequence, and connect adjacent steel structure frame units 10 through the quick connection fixing device 30 to form the main frame.

[0058] S4. Install a movable support platform 50 on a column on one side of the main frame. Lead out a first traction rope 72 from the drive mechanism 71 of the traction pulley assembly 70 and connect it to the movable support platform 50. Place the cabin module 40 on the movable support platform 50. Install a movable fixed pulley group 60 on a column on the other side of the main frame. Lead out a second traction rope 73 from the drive mechanism 71 of the traction pulley assembly 70, pass it around the movable fixed pulley group 60, and connect it to the cabin module 40.

[0059] S5. Start the drive mechanism 71 to raise the movable support platform 50 and the movable fixed pulley group 60 to a suitable height, and then pull the cabin module 40 into the set position of the main frame.
