Description

New and old building connection structures suitable for urban renewal Technical Field

[0001] This utility model relates to the field of prefabricated buildings, specifically to a connection structure between new and old buildings suitable for urban renewal. Background Technology

[0002] In towns, counties, and some urban streets across my country, there are numerous old buildings along the streets. These buildings are mostly of similar form, generally not very tall, and have relatively simple facades. However, due to years of disrepair, the exterior walls are incomplete, polluted, and damaged, resulting in a cluttered appearance that seriously affects the building's facade and even poses structural safety hazards in some cases.

[0003] Therefore, to improve the overall appearance of urban buildings and the quality of the city, "urban renewal" is an important means of building modern cities. The renovation of old building facades and structural reinforcement have become key projects in "urban renewal." Currently, the traditional construction methods for facade renovation are as follows:

[0004] 1. Remove the existing wall surface and related base materials;

[0005] 2. New keel and load-bearing structural layers are constructed, with the structural load relying on the existing building;

[0006] 3. Add new decorative materials, including on-site cutting, welding, and processing.

[0007] Therefore, traditional facade renovation methods have certain limitations, such as long cycle, complex construction process, construction pollution, and significant impact on business operations and residents. Summary of the Invention

[0008] This utility model aims to provide a connection structure between new and old buildings suitable for urban renewal, in order to solve the problems of complex construction and long cycle in traditional facade renovation construction.

[0009] To achieve the above objectives, the present invention adopts the following technical solution: a new and old building connection structure suitable for urban renewal, including a new support unit, an installation plate for detachable installation on the exterior of the old building, and a connecting longitudinal beam for connecting the new support unit and the installation plate. The new support unit includes a column base and a support column detachably connected to the column base. The two ends of the connecting longitudinal beam are detachably connected to the support column and the installation plate, respectively.

[0010] The advantages of this solution are: by using independently installed new support units and mounting plates on the exterior of the old building, and then connecting the new support units to the old building via connecting longitudinal beams, the new support units can reinforce the structure of the old building. Furthermore, all components in this solution are assembled using detachable connections, eliminating the need for on-site material cutting and welding. This simplifies the construction process, speeds up assembly, and shortens the construction cycle. Additionally, the construction process avoids high noise and dust pollution issues.

[0011] Preferably, as an improvement, the mounting plate and the support column are detachably connected with grooved connectors, and the grooves of the two grooved connectors are opposite each other.

[0012] Preferably, as an improvement, both the surface of the groove connector that connects to the mounting plate and the mounting plate are provided with corresponding connection holes.

[0013] Preferably, as an improvement, the column base includes a base plate, on which at least two connecting steel members are provided, and on which a mounting base for fixing and installing the support column is provided, the mounting base including a connecting plate connected to the base plate and a connecting body fixedly installed on the connecting plate.

[0014] Preferably, as an improvement, the 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.

[0015] Preferably, as an improvement, the side wall of the mounting plate is provided with an auxiliary plate, and the auxiliary plate has multiple hollow holes.

[0016] Preferably, as an improvement, an auxiliary support block is detachably connected to the mounting plate, and the auxiliary support block abuts against the bottom of the groove connector. Attached Figure Description

[0021] The following detailed description illustrates the specific implementation method:

[0022] 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, mounting plate 7, connecting longitudinal beam 8, reinforcing plate 9, protective cover 10, support column 11, groove connector 12, auxiliary plate 13, column base 14.

[0023] This embodiment is basically as shown in Figures 1 and 2: a new and old building connection structure suitable for urban renewal, including a new support unit, an installation plate 7 for detachable installation on the exterior of the old building, and connecting longitudinal beams 8 for connecting the new support unit and the installation plate 7. The number of connecting longitudinal beams 8 varies depending on the actual stress conditions; in this embodiment, two connecting longitudinal beams 8 are installed. The new support unit includes a column base 14 and a support column 11 detachably connected to the column base 14. The two ends of the connecting longitudinal beam 8 are detachably connected to the support column 11 and the installation plate 7, respectively.

[0024] As shown in Figures 3 and 4, the column base 14 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 a reinforcing bar. The connecting steel member 2 is fixed to the base plate 1 by bolts. A mounting base for fixing the support column 11 is bolted to the base plate 1. The mounting base includes a connecting plate 3 connected to the base plate 1 and a connecting body 4 fixedly installed on the connecting plate 3. The connecting body 4 includes a square structure formed by four steel plates. The steel plates have mounting holes for connecting to the support 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 connecting body 4, thereby ensuring the stability of the bottom of the support column 11.

[0025] The lower end of the support column 11 is fitted onto the connector 4, and its upper sidewall and mounting plate 7 are detachably connected with grooved connectors 12. The grooves of the two grooved connectors 12 face each other. The specific connection method is as follows: multiple first connection holes are opened on the mounting plate 7 and the support column 11, and second connection holes corresponding to some of the first connection holes are provided on the grooved connectors 12. In this way, the grooved connectors 12 and the mounting plate 7 can be fixed to the wall simultaneously with chemical bolts through the preset first and second connection holes, without the need for two-step installation (installing them in pairs first and then installing them with a third party), thus speeding up the assembly cycle. The remaining first connection holes on the mounting plate 7 and the support column 11 can be used to assemble other components, such as auxiliary support blocks. By abutting the auxiliary support blocks against the grooved connectors 12, the support strength of the connecting longitudinal beam 8 can be reinforced.

[0026] Both ends of the connecting longitudinal beam 8 are respectively fitted onto the grooved connector 12 and fixed by high-strength bolts.

[0027] As shown in Figure 2, when the mounting plate 7 is installed on a wall that is not a structural beam or column, considering that the wall does not have the same load-bearing capacity as a structural beam or column, auxiliary plates 13 are horizontally fixedly installed on both sides of the mounting plate 7 to increase the load-bearing surface of the mounting plate 7 and thus achieve multi-point connection between the mounting plate 7 and the wall, thereby improving its load-bearing strength. Secondly, multiple perforated holes are provided on the auxiliary plates 13. These perforated holes serve both a decorative effect and as connection holes; different perforated holes can be selected as connection holes to the wall depending on the different connection points.

[0028] When the mounting plate 7 is installed on the structural beam or structural column, an auxiliary plate 13 with perforated holes can also be installed, which can serve a decorative purpose.

[0029] Furthermore, considering that during the actual renovation process, after the base plate 1 is fixedly installed on the ground, the actual installation distance between the support column 11 and the old building structure may be adjusted when installing the support column 11. Therefore, in this solution, as shown in Figure 4, the mounting base and the base plate 1 are designed to be bolted together with an adjustable connection position. Specifically, the mounting base and the base plate 1 are equipped with a position adjustment part, which includes a first adjustment slot on the front and rear sides of the base plate 1 and a second adjustment slot 5 on the connecting plate 3. The first adjustment slot and the second adjustment slot 5 are located on the same vertical projection plane. Locking elements 6, which are bolts, are installed in the first adjustment slot and the second adjustment slot 5 to lock and fix the base plate 1 and the mounting base. A protective cover 10 is installed on the side wall of the base plate 1. The protective cover 10 can be made of decorative materials such as stone, which can provide both protection and decoration.
