Description

Technical Field

[0001] This utility model relates to the field of steel structure building construction technology, specifically to a steel structure building with integrated decoration modules. Background Technology

[0002] The introduction of low-carbon green buildings has effectively reduced the workload and construction pollution on construction sites. With the vigorous promotion and development of modular prefabricated buildings, on-site labor and construction pollution have been greatly reduced, and construction time and costs have been saved. This meets the requirements for low-carbon emission reduction and green buildings.

[0003] In traditional building interior decoration work, the installation of mechanical and electrical equipment is usually carried out after the civil engineering is completed. Furthermore, the main power lines of the equipment must be installed first, followed by decoration and the integration of secondary mechanical and electrical equipment. However, this traditional approach results in a large amount of labor on-site, and the inconsistent quality of workmanship among different workers introduces uncontrollable factors into the project schedule and construction costs.

[0004] Existing modular prefabricated buildings, using prefabricated building modules, can meet the integration and standardization of decoration, saving a lot of labor in decoration construction and greatly improving construction efficiency. However, the embedded modules in existing modular buildings are prefabricated modules within the main structure after completion. The main structure is a modular structure, and installation requires slab lowering or backfilling, which involves a lot of wet work after the prefabricated modules are installed. Traditional prefabricated modules require floor systems due to fully prefabricated decoration, which can easily lead to cavities between the floor slab and the floor system, resulting in relatively poor structural comfort. Moreover, double-layer slabs plus cavities increase the floor thickness, requiring higher ceiling height. Embedded modules are usually pushed in, which requires extremely high flatness of the installation site and clear clearance along the path. The path of the prefabricated module cannot contain equipment shafts or stairwells, making installation conditions extremely limited. Furthermore, equipment systems along the path can only be installed after the prefabricated modules are in place, resulting in complex interleaving of multiple processes and cumbersome installation techniques. Compared to traditional hoisting modules, the existing push-to-install prefabricated modules require the installation of a module installation platform, which places extremely high demands on the structural design of the installation platform. Utility Model Content

[0005] Therefore, this utility model aims to solve the problems of high installation requirements and complex installation in existing modular prefabricated buildings, thereby providing a steel structure building with integrated decoration modules.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] A steel structure building with integrated decoration modules includes a steel structure frame body and integrated modules disposed within the steel structure frame body. The steel structure frame body is raised so that its bottom is suspended. Open holes are provided around the four sides, bottom and top of the steel structure frame body. The bottom of the integrated module is provided with a bottom support steel beam suitable for connection with the steel structure frame body. The integrated module is provided with a placement slot suitable for placing electromechanical systems.

[0008] Furthermore, the integrated module is an integrated box, the bottom of which is provided with a concrete base plate, and the bottom support steel beam is provided at the bottom of the concrete base plate away from the integrated box, and the bottom support steel beam and the bottom structure of the main steel frame are located on the same plane.

[0009] Furthermore, the bottom support steel beam includes a first bottom rod and a second bottom rod respectively disposed on opposite sides of the bottom of the integrated box, a fixed rod connected between the first bottom rod and the second bottom rod, and two diagonal rods connected between the first bottom rod and the fixed rod. One end of the two diagonal rods is connected to both ends of the first bottom rod, and the other end of the two diagonal rods is connected to the end of the fixed rod away from the first bottom rod.

[0010] Furthermore, the integrated housing is provided with a suspended ceiling on top, and the placement groove is provided on the suspended ceiling.

[0011] Furthermore, the top of the integrated housing is also provided with a top support steel beam located above the suspended ceiling.

[0012] Furthermore, the top support steel beam includes a support frame with the same circumference shape as the top of the integrated box, longitudinal beams connected to opposite ends of the support frame, and multiple transverse beams spaced apart and connected to opposite sides of the support frame, with the multiple transverse beams being perpendicularly connected to the longitudinal beams.

[0013] Furthermore, the bottom of the integrated box is provided with an electromechanical installation steel frame located below the bottom support steel beam, and the electromechanical installation steel frame is located in the suspended position at the bottom of the main body of the steel structure frame.

[0014] Furthermore, the main body of the steel structure frame includes multiple vertically arranged columns, multiple top beams connected between the tops of the multiple columns, and multiple bottom beams connected between the multiple columns and located near the bottom of the columns; the inner sides of the two top beams and the two bottom beams located on opposite sides are provided with fasteners suitable for connecting with the bottom support steel beams.

[0015] Furthermore, the fastener includes two fixed steel plates fixed to the main body of the steel structure frame, each fixed steel plate having a connecting hole and a connecting steel nail, and the distance between the two fixed steel plates being adapted to the length of the bottom supporting steel beam.

[0016] Furthermore, the integrated enclosure includes multiple light steel keel partition walls that form a rectangular frame. The outer side of the light steel keel partition walls is provided with an exterior finish, and the inner side of the light steel keel partition walls is provided with an interior finish. Wiring holes are provided on both the concrete base plate and the ceiling.

[0017] The technical solution of this utility model has the following advantages:

[0018] 1. The steel structure building with integrated decoration modules provided by this utility model features a steel frame main body with open holes on all four sides, bottom, and top. This facilitates the hoisting and installation of integrated modules within the steel frame main body through these open holes, making module installation unrestricted. Furthermore, it allows for installation of integrated modules from the side or bottom after the steel frame main body is topped out, significantly reducing the installation difficulty of prefabricated modules. By setting bottom support steel beams on the prefabricated modules, the structural strength reduction caused by the open holes at the bottom of the steel frame main body can be compensated for. This also improves the structural strength of the integrated modules during transportation and, after subsequent connection to the steel frame main body, the bottom support steel beams can distribute some of the stress, further enhancing the structural strength of the integrated modules. The integrated modules are equipped with placement slots suitable for placing electromechanical systems, allowing the necessary electromechanical systems to be installed directly before decoration. Upon arrival on site, only the pipelines of the electromechanical systems need to be connected to the on-site power supply, eliminating the need for on-site drilling and installation of the electromechanical systems, thus saving a significant amount of construction work and labor. This type of steel structure building can achieve full prefabrication and integration in the factory. On the construction site, it only needs to be hoisted and connected to meet the functional requirements of the building, reducing on-site wet work processes and improving the standardization of steel structure building decoration.

[0019] 2. The steel structure building with integrated decoration modules provided by this utility model has integrated modules as integrated boxes. A concrete base slab is provided at the bottom of the integrated box, and a bottom supporting steel beam is located at the bottom of the concrete base slab away from the integrated box. The bottom supporting steel beam and the bottom structure of the main steel frame are on the same plane. This arrangement means that only a single concrete base slab is needed between the integrated module and the main steel frame, saving building height and increasing the clear height within the building's limited height. Furthermore, this structure, with only one floor slab between the integrated module and the main steel frame, reduces the amount of floor pouring required on the construction site.

[0020] 3. The steel structure building with integrated decoration modules provided by this utility model includes a bottom support steel beam comprising a first bottom rod and a second bottom rod respectively disposed on opposite sides of the bottom of the integrated box, a fixed rod connecting the first bottom rod and the second bottom rod, and two diagonal rods connecting the first bottom rod and the fixed rod. One end of each diagonal rod is connected to both ends of the first bottom rod, and the other end of each diagonal rod is connected to the end of the fixed rod away from the first bottom rod. This arrangement provides the horizontal stiffness required for the main steel frame through the bottom support steel beam, preventing the weakening of the bottom planar stiffness of the main steel frame due to open openings. Simultaneously, after the integrated box is connected to the main steel frame, the bottom support steel beam provides strong stiffness to the module. Furthermore, the bottom steel beam can serve as a bottom tray during the hoisting of the integrated module, providing a hoisting anchor point. During hoisting, the lifting equipment can be directly connected to the bottom support steel beam, ensuring the stiffness of the integrated module and reducing the need for other hoisting reinforcement measures.

[0021] 4. The steel structure building with integrated decoration modules provided by this utility model has a suspended ceiling on the top of the integrated box, and a placement groove on the suspended ceiling. This design facilitates the installation of electromechanical systems and wiring on the top of the integrated box, eliminating the need to drill holes in the side walls of the integrated box for wiring, thus simplifying the construction process.

[0022] 5. The steel structure building with integrated decoration modules provided by this utility model also has a top support steel beam located above the ceiling on the top of the integrated box. This arrangement can provide support for the wiring of the electromechanical system and lines installed in the placement slot, and improve the structural strength of the top of the integrated box.

[0023] 6. The steel structure building with integrated decoration modules provided by this utility model includes two fixed steel plates fixed to the main body of the steel structure frame. Each fixed steel plate has a connecting hole with a connecting steel nail. The distance between the two fixed steel plates is adapted to the length of the bottom supporting steel beam. With this configuration, the bottom supporting steel beam can be fixedly installed to the main body of the steel structure frame using the fixed steel plates and the fixing steel nails.

[0031] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0032] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0035] like Figures 1-5 The steel structure building shown includes a steel frame main body 1 and an integrated module 2 set inside the steel frame main body 1. The steel frame main body 1 is raised so that its bottom is suspended. Open holes 3 are provided on all four sides, bottom and top of the steel frame main body 1. The bottom of the integrated module 2 is provided with a bottom support steel beam 4 suitable for connecting with the steel frame main body 1. The integrated module 2 is provided with a placement slot 5 suitable for placing the electromechanical system 23.

[0036] This type of steel structure building with integrated decoration modules utilizes a steel frame main body 1 with open openings 3 on all four sides, bottom, and top. This allows for the easy hoisting and installation of integrated modules 2 within the steel frame main body 1 through these openings, making the installation of integrated modules 2 unrestricted. Furthermore, integrated modules 2 can be installed from the side or bottom after the steel frame main body 1 is topped out, significantly reducing the difficulty of installing prefabricated modules. By incorporating bottom support steel beams 4 into the prefabricated modules, the structural strength of the steel frame main body is mitigated by the open openings 3 at the bottom. This also enhances the structural strength of integrated modules 2 during transportation and, after connection to the steel frame main body 1, distributes some of the stress through the bottom support steel beams 4, further improving the structural strength of integrated modules 2. The integrated modules 2 are equipped with placement slots 5 suitable for placing electromechanical systems 23, allowing the necessary electromechanical systems 23 to be installed directly before decoration. Upon arrival on site, only the pipelines of the electromechanical systems 23 need to be connected to the on-site power supply, eliminating the need for on-site drilling and installation of the electromechanical systems 23, thus saving significant construction steps and labor costs associated with on-site electromechanical installation. This type of steel structure building allows for complete prefabrication and integration in the factory. On-site installation only requires hoisting and connection to meet the building's functional requirements, reducing on-site wet work and improving the standardization of steel structure building decoration. It reduces the number of on-site floor slabs and secondary steel beams, saves on hoisting operations, reduces on-site wet work, and utilizes a completely dry hoisting method, saving materials and promoting green construction. The on-site environment is also highly civilized.

[0037] In an alternative embodiment, the bottom of the integrated housing is provided with an electromechanical installation steel frame 16 located below the bottom support steel beam 4, and the electromechanical installation steel frame 16 is located in the suspended position at the bottom of the main body of the steel structure frame 1.

[0038] In this embodiment, the main body of the steel structure frame 1 includes multiple vertically arranged columns 17, multiple top beams 18 connected between the tops of the multiple columns 17, and multiple bottom beams connected between the multiple columns 17 and close to the bottom of the columns 17; the inner sides of the two top beams 18 and the two bottom beams located on opposite sides are provided with fasteners 19 suitable for connecting with the bottom support steel beams 4.

[0039] Specifically, the fastener 19 includes two compartmentalized fixing steel plates fixed to the main body of the steel frame 1. Each fixing steel plate has connecting holes with connecting steel nails. The spacing between the two fixing steel plates matches the length of the bottom supporting steel beam 4. Mounting holes matching the connecting holes are provided at both ends of the bottom supporting steel beam 4. This configuration allows the bottom supporting steel beam 4 to be fixedly installed on the main body of the steel frame 1 using the fixing steel plates and fixing steel nails. Specifically, two sets of fasteners 19 are provided on the inner side of each top beam 18 and bottom beam (the number of fasteners 19 on the top beam 18 and bottom beam of the same main body of the steel frame 1 is the same). Each set of fasteners 19 includes two spaced-apart fixing steel plates. This configuration allows two integrated boxes to be installed on one main body of the steel frame 1 to form two building spaces, or the adjacent wall of two integrated boxes to be opened up to form a larger interior space. In an alternative embodiment, three or four sets of fasteners 19 may be provided on the inner side of each top beam 18 and bottom beam, and the specific number can be set according to the requirements.

[0040] In this embodiment, the integrated module 2 is an integrated box, with a concrete base slab 6 at its bottom. A bottom supporting steel beam 4 is located at the bottom of the concrete base slab 6, away from the integrated box, and the bottom supporting steel beam 4 is on the same plane as the bottom structure of the steel frame main body 1. This arrangement means that only the concrete base slab 6 exists between the integrated module 2 and the steel frame main body 1, saving building height and increasing the clear height within the building's limited height. Furthermore, this structure, with only one floor slab between the integrated module 2 and the steel frame main body 1, reduces the amount of floor pouring required on the construction site.

[0041] In this embodiment, the integrated box includes multiple light steel keel partition walls 20 that form a rectangular frame. The outer side of the light steel keel partition wall 20 is provided with an exterior finish 21, and the inner side of the light steel keel partition wall 20 is provided with an interior finish 22.

[0042] In this embodiment, the bottom support steel beam 4 includes a first bottom rod 7 and a second bottom rod 8 respectively disposed on opposite sides of the bottom of the integrated box, a fixed rod 9 connecting the first bottom rod 7 and the second bottom rod 8, and two diagonal rods 10 connecting the first bottom rod 7 and the fixed rod 9. One end of the two diagonal rods 10 is connected to both ends of the first bottom rod 7, and the other end of the two diagonal rods 10 is connected to the end of the fixed rod 9 away from the first bottom rod 7. This arrangement provides the horizontal stiffness required for the main body of the steel structure frame 1 through the bottom support steel beam 4, preventing the weakening of the bottom planar stiffness of the main body of the steel structure frame 1 due to the opening 3. Simultaneously, after the integrated box is connected to the main body of the steel structure frame 1, the bottom support steel beam 4 can provide strong stiffness for the module. Furthermore, the bottom steel beam can serve as a bottom tray during the hoisting of the integrated module 2, providing a hoisting anchor point. During the hoisting of the integrated module 2, the lifting equipment can be directly connected to the bottom support steel beam 4, ensuring the stiffness of the integrated module 2 and reducing the need for other hoisting reinforcement measures. Because the integrated enclosure has a bottom support steel beam 4, its decoration, structural design, and electromechanical layout can all be completed in the factory. After the integrated enclosure is hoisted, only the on-site pipelines need to be connected to the electromechanical wiring on the integrated enclosure, resulting in a high degree of integration and standardization. This reduces on-site decoration and electromechanical installation work.

[0043] Specifically, a suspended ceiling 11 is installed on the top of the integrated enclosure, and a mounting groove 5 is provided on the suspended ceiling 11. This design facilitates the installation of the electromechanical system 23 and wiring on the top of the integrated enclosure, eliminating the need to drill holes in the side walls of the integrated enclosure for wiring, thus simplifying the construction process. Specifically, wiring holes are provided on both the concrete base slab 6 and the suspended ceiling 11.

[0044] In this embodiment, a top support steel beam 12 is also provided on the top of the integrated enclosure, located above the suspended ceiling 11. This arrangement provides support for the electromechanical system 23 and wiring installed in the placement slot 5, improving the structural strength of the top of the integrated enclosure. Specifically, the top support steel beam 12 includes a support frame 13 with the same perimeter shape as the top of the integrated enclosure, longitudinal beams 14 connected to opposite ends of the support frame 13, and multiple transverse beams 15 spaced apart and connected to opposite sides of the support frame 13. The transverse beams 15 are perpendicularly connected to the longitudinal beams 14.

[0045] In summary, this type of steel structure building with integrated decoration modules, by setting up a steel frame main body 1 with open openings 3 on all four sides, bottom, and top, facilitates the hoisting and installation of integrated modules 2 into the steel frame main body 1 through the open openings 3. This allows for unrestricted installation of integrated modules 2 and enables installation from the side or bottom after the steel frame main body 1 is topped out, greatly reducing the installation difficulty of prefabricated modules. By setting bottom support steel beams 4 on the prefabricated modules, the structural strength reduction problem caused by the open openings 3 at the bottom of the steel frame main body can be compensated; it can also improve the structural strength of integrated modules 2 during transportation; and after integrated modules 2 are subsequently connected to the steel frame main body 1, the bottom support steel beams 4 can distribute some of the force, further improving the structural strength of integrated modules 2. The integrated module 2 is equipped with a placement slot 5 suitable for placing the electromechanical system 23, allowing the required electromechanical system 23 to be installed directly before decoration. After arriving on site, only the pipelines on the electromechanical system 23 need to be connected to the on-site power supply, eliminating the need for drilling and installation of the electromechanical system 23 on-site, thus saving a large number of construction procedures and labor costs associated with on-site electromechanical installation. This type of steel structure building can achieve full prefabrication and integration in the factory. On-site, only hoisting and connection are required to meet the functional requirements of the building, reducing on-site wet work procedures and improving the standardization of steel structure building decoration.

[0046] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
