Description

Technical Field

[0001] This application relates to the field of building engineering technology, specifically a steel structure diagonal bracing force transmission foundation structure for the renovation of existing buildings in underground confined spaces. Background Technology

[0002] In the field of building engineering, the renovation of existing buildings often faces the problem of limited underground space, especially when there are obstacles such as underground pipe trenches, making traditional excavation construction methods difficult to implement. With the acceleration of urbanization, more and more existing buildings need to be renovated to meet new usage requirements. Therefore, how to carry out effective structural renovation within limited spaces has become an urgent problem to be solved.

[0003] Currently, the methods commonly used in the industry include reinforcing the original structure and adding temporary supports. However, these methods all require large-scale excavation on the basis of the original structure, which requires a certain amount of construction space. Furthermore, they will damage the foundation and supporting facilities of the original structure, making construction difficult, costly, and having a significant impact on the original structure. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a steel structure diagonal bracing force-transfer foundation structure for the renovation of existing buildings in underground confined spaces. This structure offers advantages such as simple construction, no need for large-scale excavation, reduced impact on the original structure, structural stability, clear load transfer path, and improved structural safety. It solves the problems of currently common industry methods, including reinforcing the original structure and adding temporary supports, which all require large-scale excavation on the original structure's foundation, necessitate sufficient construction space, damage the original structure's foundation facilities, and result in high construction difficulty, high cost, and significant impact on the original structure.

[0005] To achieve the goals of simplified construction, elimination of large-scale excavation, reduced impact on the original structure, structural stability, clear load transfer path, and improved structural safety, this application provides the following technical solution: A steel structure diagonal bracing force-transfer foundation structure for the renovation of existing buildings in underground confined spaces, comprising an original support column, a first floor slab, and a second floor slab. The outer surface of the middle part of the original support column passes through and is fixedly connected to the first and second floor slabs. The first and second floor slabs are distributed sequentially from bottom to top on the outer surface of the middle part of the original support column. A first connecting anchor plate is provided on one side of the original support column by fixing bolts. One side of the first connecting anchor plate is fixedly connected to one end of a steel structure diagonal brace by a first connecting assembly. The other end of the steel structure diagonal brace is fixedly connected to the bottom of a second connecting anchor plate by a second connecting assembly. The second connecting anchor plate is set at the bottom of the first floor slab by fixing bolts. A concrete structural column is provided at the top of the first floor slab at a position corresponding to the second connecting anchor plate. The end of the concrete structural column away from the first floor slab is located at the bottom of the second floor slab.

[0006] The above scheme uses steel structural diagonal braces on one side of the original support column to support the first floor slab. The steel structural diagonal braces, together with the original support column, provide stable support for the concrete structural column at the top of the first floor slab. This achieves the effects of simple construction, no need for large-area excavation, reduced impact on the original structure, structural stability, clear load transfer path, and improved structural safety.

[0007] Furthermore, the first connecting assembly includes a first connecting plate, which is disposed at one end of the steel structure diagonal brace, and the first connecting plate is fixedly connected to the first connecting anchor plate by fixing bolts.

[0008] Through the above scheme, by using the fixing bolts to fix the first connecting plate to the first connecting anchor plate, one end of the steel structure diagonal brace can be stably fixed to the first connecting anchor plate, thereby enabling the original support column to provide stable support for the steel structure diagonal brace.

[0009] Furthermore, the outer surface of the middle part of the first connecting plate is slidably disposed within the inner wall of the middle part of the first positioning frame, and the first positioning frame is disposed on one side of the first connecting anchor plate.

[0010] The above solution allows for the positioning of the first connecting plate by setting the first positioning frame, ensuring the stability of the first connecting plate when it is installed on the first connecting anchor plate and improving the work efficiency when installing the first connecting plate on the first connecting anchor plate.

[0011] Furthermore, the second connecting assembly includes a second connecting plate, which is disposed at one end of the steel structure diagonal brace, and the second connecting plate is fixedly connected to the bottom of the second connecting anchor plate by fixing bolts.

[0012] Through the above scheme, by using the fixing bolts to fix the second connecting plate to the second connecting anchor plate, one end of the steel structure diagonal brace can be stably fixed to the second connecting anchor plate. In this way, the steel structure diagonal brace, together with the original support column, can provide a stable support point for the concrete structural column at the top of the first floor slab.

[0013] Furthermore, two second positioning frames are provided at the bottom of the second connecting anchor plate. The second positioning frames are L-shaped and symmetrically arranged. The inner sidewall of the second positioning frame is slidably connected to the side of the second connecting plate, and the second connecting plate is located above the short side of the second positioning frame.

[0014] The above solution allows the second connecting plate to slide into the interior of the two second positioning frames from one end, thus positioning the second connecting plate in place. This, in conjunction with the first connecting plate and the first positioning frame, provides stable support for the steel structure diagonal brace before it is securely fixed. This facilitates the use of fixing bolts to fix the steel structure diagonal brace without requiring additional support tools. Furthermore, during installation, the first and second connecting plates can be simultaneously slid into the first and second positioning frames by translating the steel structure diagonal brace, improving the efficiency of the installation process.

[0015] Furthermore, a first connecting bar is provided on the top of the second connecting anchor plate. The first connecting bar extends through the first floor slab into the interior of the concrete structural column. A second connecting bar is provided inside the concrete structural column. One end of the first connecting bar is fixedly connected to one end of the second connecting bar.

[0016] The above scheme enhances the connection strength between the second connecting anchor plate and the concrete structural column by fixing the first connecting bar and the second connecting bar, thereby improving the stability and load-bearing capacity of the entire structure, effectively transferring loads, and ensuring the overall safety of the structure.

[0017] Furthermore, a tie rod is provided between the original support column and the steel structure diagonal brace. One end of the tie rod is located on one side of the third connecting anchor plate, and the third connecting anchor plate is located on one side of the original support column by fixing bolts. The other end of the tie rod is connected to the steel structure diagonal brace by the third connecting assembly.

[0018] The above solution provides a tensile force to the steel structure bracing by installing diagonal tie rods, which further enhances the connection strength between the original support column and the steel structure bracing rods, thereby improving the stability and load-bearing capacity of the entire structure.

[0019] Furthermore, the third connecting component includes a sliding sleeve, which is slidably disposed on the outer surface of the middle part of the steel structure diagonal brace. An insert plate is provided on one side of the sliding sleeve, and the outer surface of the middle part of the insert plate is slidably connected to the inner wall of the middle part of the connecting frame. The connecting frame is U-shaped and is disposed at one end of the diagonal brace. The insert plate and the connecting frame are fixedly connected by fixing bolts.

[0020] Through the above scheme, the design of the third connecting component can ensure that the connection between the tie rod and the steel structure diagonal brace is both flexible and firm. The setting of the sliding sleeve and the insert plate makes it easy to slide the insert plate into the connection frame for connection after the tie rod is installed on the third connecting anchor plate, according to the position of the tie rod. This facilitates the connection between the tie rod and the steel structure diagonal brace. Furthermore, the setting of the sliding sleeve eliminates the need to drill holes in the steel structure diagonal brace for connection, without damaging the structure of the steel structure diagonal brace.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] This is a steel structure diagonal bracing load-transfer foundation structure for the renovation of existing buildings in underground confined spaces. The steel structure diagonal bracing is set on one side of the original support column, so that the steel structure diagonal bracing supports the first floor slab. The steel structure diagonal bracing, together with the original support column, provides stable support for the concrete structural column at the top of the first floor slab. It achieves the effects of simple construction, no need for large-area excavation, reduced impact on the original structure, structural stability, clear load transfer path, and improved structural safety.

[0023] This is a steel structure diagonal bracing force transmission foundation structure for the renovation of existing buildings in underground confined spaces. Through the cooperation of a first connecting component and a second connecting component, the position of the steel structure diagonal bracing rod can be temporarily fixed conveniently during installation. This facilitates subsequent operations on the steel structure diagonal bracing rod without the need for other supporting equipment to provide temporary support, thus improving the installation efficiency of the steel structure diagonal bracing rod.
