Description

Technical Field

[0001] This utility model relates to the field of prefabricated building structures, specifically to the foundation structure of small-scale excavation buildings in urban renewal. Background Technology

[0002] In urban construction, the scale of buildings is constantly increasing, including many old buildings. To improve the overall appearance and quality of urban architecture, and to prevent large-scale demolition and construction, "urban renewal" is an important means of building modern cities. The renovation of old building facades and structural reinforcement have become important methods of "urban renewal." Among these, the small-scale excavation of building foundations in urban renewal is one of the most crucial aspects of the renovation process. This foundation serves as the load-bearing component for installing steel columns on the renovated building facade, and is directly related to the overall stability of the building facade.

[0003] During the actual renovation and construction process, since businesses and residents are still conducting their normal business and daily lives, the current issue is how to ensure that the construction process does not disrupt the business operations of businesses and the normal lives of residents. Utility Model Content

[0004] This utility model aims to provide a small-excavation building foundation structure for urban renewal projects, in order to solve the problem of not affecting business operations and residents' normal lives during the renovation and construction process.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a small-excavation building foundation structure for urban renewal, including a base plate, on which at least two connecting steel members are detachably connected, and a steel column mounting base for fixing and installing steel columns is provided on the base plate, the steel column mounting base including a connecting plate connected to the base plate and a connecting body fixedly installed on the connecting plate.

[0006] The principle and advantages of this scheme are as follows: Drill pile holes on the ground at the locations corresponding to the connecting steel parts, then pour concrete into the pile holes and insert the connecting steel parts on the base plate into the concrete in the pile holes accordingly. After the concrete reaches the design strength, the steel column can be fixedly connected to the connector.

[0007] This solution requires minimal construction effort, necessitating only on-site assembly of the components. Furthermore, the drilling area is small, meaning that during actual construction, only holes need to be drilled in the road surface to be modified for installing connecting steel components. Additionally, all components in this solution are prefabricated and can be quickly assembled on-site, solving the problems of high noise and dust associated with traditional new construction or renovation projects. Therefore, businesses and residents can continue their normal operations and lives.

[0008] Preferably, as an improvement, the steel column mounting base is bolted to the base plate and the connection position is adjustable.

[0009] Preferably, as an improvement, the steel column mounting base is provided with a position adjustment part that cooperates with the base plate. The position adjustment part includes adjustment slots respectively provided on the connecting plate and the base plate, and a locking element is provided in the adjustment slots.

[0010] Preferably, as an improvement, the substrate is provided with auxiliary slots located on the extension line of the adjustment slots.

[0011] Preferably, as an improvement, the connector includes a square structure formed by connecting at least three steel plates, with connection holes on the steel plates for connecting with steel columns, and a reinforcing plate fixedly connected to each steel plate.

[0012] Preferably, as an improvement, a protective cover is also included to protect the substrate and the steel column mounting base.

[0013] Preferably, as an improvement, the bottom of the substrate is provided with a concrete counterweight for mounting connecting steel components. Attached Figure Description

[0015] Figure 2 This is a schematic diagram of the structure of Example 1 equipped with a protective cover and a steel column (the front side of the protective cover is not shown).

[0016] Figure 3 This is a schematic diagram of the structure of Example 2. Detailed Implementation

[0017] The following detailed description illustrates the specific implementation method:

[0018] The reference numerals in the accompanying drawings include: base plate 1, connecting steel part 2, connecting plate 3, connecting body 4, second adjusting strip hole 5, locking part 6, auxiliary strip hole 7, concrete counterweight block 8, reinforcing plate 9, protective cover 10, and steel column 11.

[0019] Example 1

[0020] This embodiment is basically as shown in the appendix. Figure 1 , Figure 2 As shown: The small-excavation building foundation structure in urban renewal includes a base plate 1. A connecting steel member 2 is installed at each of the four corners of the base plate 1. The connecting steel member 2 can be made of reinforcing steel. The upper part of the connecting steel member 2 is threaded. A connecting steel pipe passes through the base plate 1 and is fixed to the base plate 1 by nuts. The advantage of this connection method is that the installation length of the connecting steel member 2 is adjustable. In appropriate scenarios, the connection position between the nut and the connecting steel member 2 can be adjusted according to the length of the connecting steel member 2 to be embedded.

[0021] A steel column mounting base for fixing the steel column 11 is bolted to the base plate 1. The steel column mounting base includes a connecting plate 3 connected to the base plate 1 and a connector 4 fixedly mounted on the connecting plate 3. The connector 4 includes a square structure composed of four steel plates. The steel plates are provided with connecting holes for connecting to the steel column 11. A triangular reinforcing plate 9 is welded to each steel plate. The bottom of the reinforcing plate 9 is welded to the connecting plate 3 to enhance the stability of the connector 4, thereby ensuring the stability of the bottom of the steel column 11. In this design, the reinforcing plates are located inside the connector to reduce the footprint.

[0022] Considering that during the actual renovation process, after the base plate 1 is fixedly installed on the ground, the actual installation distance of the steel column 11 from the original building may be adjusted when installing the steel column 11. Therefore, in this solution, the steel column mounting base and the base plate 1 are designed to be bolted together and the connection position is adjustable. Specifically, the steel column mounting base and the base plate 1 are provided with a position adjustment part. The position adjustment part includes a first adjustment strip hole opened on the front and rear sides of the base plate 1 and a second adjustment strip hole 5 opened on the connecting plate 3. The first adjustment strip hole and the second adjustment strip hole 5 are located on the same vertical projection plane. Locking parts 6 for locking and fixing the base plate 1 and the steel column mounting base are installed in the first adjustment strip hole and the second adjustment strip hole 5. The locking parts 6 are bolts.

[0023] Secondly, to allow for a wider adjustment range of the steel column mounting base while ensuring the supporting strength of the base plate 1, an independent auxiliary slot 7 is provided on the extension line of the second adjustment slot 5 on the base plate 1. This ensures that the base plate 1 remains intact between the second adjustment slot 5 and the auxiliary slot 7, guaranteeing its supporting strength. When the steel column mounting base is adjusted to a greater distance to the right, the two ends of the first adjustment slot can be placed at the second adjustment slot 5 and the auxiliary slot 7 respectively, and then secured with bolts.

[0024] A protective cover 10 is installed on the side wall of the substrate 1. The protective cover 10 can be made of decorative materials such as stone, which can serve both protective and decorative purposes.

[0025] The specific implementation process is as follows: The steel column mounting base, base plate 1, and connecting steel parts 2 are connected as a whole. Pit holes are drilled on the ground corresponding to the four connecting steel parts 2. Concrete is then poured into the pile holes, and the connecting steel parts 2 on the base plate 1 are inserted into the concrete in the pile holes accordingly. After the concrete reaches the design strength, the steel column 11 is fitted onto the connecting body 4 and the two are connected and fixed with bolts. Finally, in order to protect the structure and achieve an aesthetic effect, a marble protective cover 10 is installed around the base plate 1.

[0026] In addition, all components in this solution (connecting steel parts 2, base plate 1, and steel column mounting base) are detachably connected, which not only facilitates transportation but also facilitates on-site assembly, reducing construction difficulty and shortening the construction period.

[0027] Example 2

[0028] Depending on the actual load-bearing conditions and whether the ground surface meets the drilling requirements, for example, if the construction site is a street and the concrete paving thickness of the street is insufficient to ensure the stability of the connecting steel part 2, there may be potential load-bearing hazards in this solution.

[0029] Based on the above situation, such as Figure 3 As shown, this design features a concrete counterweight 8 at the bottom of the base plate 1 for mounting the connecting steel component 2. This concrete counterweight 8 is cast with 2.3 tons of concrete per cubic meter. This independent placement of the concrete counterweight 8 ensures a more stable connection between the connecting steel component 2 and the concrete counterweight 8, thereby guaranteeing the load-bearing stability of this design.

[0030] For aesthetic purposes, a decorative cover is fitted over the concrete counterweight block 8.
