Description

Reinforcement structures for old buildings suitable for urban renewal Technical Field

[0001] This utility model relates to the field of prefabricated building construction, specifically to a reinforcement structure for 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] To enhance the overall appearance and quality of urban architecture, "urban renewal" is a crucial means of building modern cities. For example, if a plan calls for transforming an area into a commercial street with a specific style, it requires the redevelopment of older buildings along the street. Currently, there are generally two ways to achieve this: one is to completely demolish and rebuild the existing old buildings, but this involves land acquisition, resident compensation and resettlement, demolition, and new construction, which consumes significant manpower, material resources, and financial resources; the other is to renovate the existing old buildings, and the current traditional construction method for facade renovation is as follows:

[0004] 1. First, remove the relevant base materials on the walls of the existing old building;

[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, and lay the decorative materials along the entire wall of the old building and fix them to the keel.

[0007] While this renovation method can offer some decorative and reinforcement benefits to old buildings, its effectiveness is very limited. It can only help reinforce cracked and peeling exterior walls. However, it falls short in terms of strengthening the overall structure of the building. Furthermore, this method involves a long construction period, complex procedures, significant pollution, and a substantial impact on businesses and residents. Summary of the Invention

[0008] This utility model aims to provide a reinforcement structure for old buildings suitable for urban renewal, so as to achieve structural reinforcement of old buildings.

[0009] To achieve the above objectives, this utility model adopts the following technical solution: a reinforcement structure for old buildings suitable for urban renewal, comprising a decorative support body installed on the exterior surface of the old building, wherein a reinforcing longitudinal beam is detachably connected between the decorative support body and the old building body; the decorative support body includes several column bases and supporting steel columns detachably connected to the column bases, wherein a reinforcing crossbeam is detachably connected between adjacent supporting steel columns; the column base includes a base plate, wherein at least two connecting steel members for fixing to the ground are provided on the base plate, and an mounting base for installing the supporting steel columns is also provided on the base plate, wherein the mounting base includes a connecting plate connected to the base plate and a connecting body fixedly installed on the connecting plate.

[0010] The principles and advantages of this scheme are:

[0011] 1. By independently installing decorative supports on the exterior of the old building and connecting them to the old building structure with reinforcing longitudinal beams, the decorative supports can reinforce the old building structure. Furthermore, reinforcing crossbeams connect the various supporting steel columns into a unified whole, enhancing the overall stability of the decorative supports and ensuring their reinforcement effect on the old building.

[0012] 2. In this scheme, the load-bearing part of the decorative support is the column base. By drilling pile holes in the ground, pouring concrete into the pile holes, and inserting the connecting steel parts of the column base into the concrete in the pile holes, the column base is firmly installed on the ground after the concrete reaches the design strength. In this way, the supporting force of the entire decorative support is transferred to the ground through the column base, ensuring the supporting force of the decorative support.

[0013] 3. All components in this solution are prefabricated in advance, and the components are assembled by means of detachable connection. Therefore, there is no need to cut or weld materials on site. The construction process is simple, the assembly speed is fast, and the cycle is short. At the same time, there will be no construction pollution problems such as high noise and large dust during the construction process, so it will not affect the normal business and life of businesses and residents.

[0014] 4. Independently designed decorative supports allow for a departure from the limitations of the original building's shape and style, enabling the redesign of new architectural styles based on evolving functional and aesthetic needs, such as antique-style architecture. This provides greater design flexibility for future architectural styles.

[0015] 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.

[0016] Preferably, as an improvement, the substrate is provided with auxiliary slots located on the extension line of the adjustment slots.

[0017] 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.

[0018] Preferably, as an improvement, it also includes a mounting plate that can be detachably connected to the old building structure, and the mounting plate and the supporting steel column are respectively detachably connected with grooved connectors for installing the reinforcing longitudinal beams.

[0019] Preferably, as an improvement, a decorative protective cover is provided on the peripheral wall of the substrate.

[0020] Preferably, as an improvement, the spacing between adjacent supporting steel columns is matched with the spacing between the structural columns of the old building.

[0021] Preferably, as an improvement, the decorative support is provided with decorative eaves at each floor of the old building. Attached Figure Description

[0028] The following detailed description illustrates the specific implementation method:

[0029] 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, reinforcing longitudinal beam 8, reinforcing plate 9, protective cover 10, supporting steel column 11, channel-type connecting part 12, auxiliary plate 13, column base 14, reinforcing crossbeam 15, decorative eaves 16, building body 17, decorative support body 18, grille 19, auxiliary strip hole 20, triangular frame body 21, roof crossbeam 22, reinforcing beam 23, roof 24, thermal insulation board 25, and fascia board 26.

[0030] The embodiment is basically as shown in Figure 1: A reinforcement structure suitable for old buildings in urban renewal includes at least decorative support bodies 18 installed on the front, back, left, and right sides of the old building 17. In this embodiment, the decorative support bodies 18 have a gap with the ground floor of the old building facing the street, abut against the second-floor wall, and abut against the left and right sides of the old building. The abutting parts are fixed with chemical bolts. A reinforcing longitudinal beam 8 is detachably connected between the decorative support body 18 located on the street-facing side and the old building 17. The decorative support body 18 includes several column bases 14 and supporting steel columns 11 detachably connected to the column bases 14. The spacing between adjacent supporting steel columns 11 is the same as the spacing between the structural columns of the old building 17. A reinforcing transverse beam 15 is detachably connected between adjacent supporting steel columns 11. The supporting steel columns 11, reinforcing longitudinal beams 8, and reinforcing transverse beams 15 are preferably made of hot-dip galvanized steel.

[0031] As shown in Figures 2 and 3, the column base 14 includes a base plate. A connecting steel member 2 is connected to 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 and installing the supporting steel 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 supporting 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 connecting body 4, thereby ensuring the stability of the bottom of the supporting steel column 11.

[0032] As shown in Figures 4 and 5, the mounting plate 7 is installed on the wall of the old building 17 using chemical bolts. The lower end of the supporting steel column 11 is connected to the connector 4 by high-strength bolts, and the upper side wall of the column and the mounting plate 7 are respectively bolted with slotted connectors 12. The specific connection method is as follows: multiple first connection holes are opened on the mounting plate 7 and the supporting steel column 11, and the slotted connectors 12 are provided with second connection holes corresponding to the first connection holes. In this way, the slotted connectors 12 and the mounting plate 7 can be simultaneously fixed to the wall with chemical bolts through the preset first connection holes and second connection holes, without the need for two-step installation (installing two at a time and then installing with a third party), thus speeding up the assembly cycle. The slots of the two slotted connectors 12 are opposite each other, and the two ends of the reinforcing longitudinal beam 8 are respectively fixed to the slotted connectors 12 with high-strength bolts. Several reinforcing longitudinal beams can be set in the same place according to the actual situation.

[0033] The two adjacent supporting steel columns 11 are also bolted with corresponding grooved connectors 12, and the two ends of the reinforcing beam 15 are fixed to the grooved connectors 12 by high-strength bolts.

[0034] Auxiliary plates 13 with perforations are installed on both sides of the mounting plate 7 and between the supporting steel columns 11 and the reinforcing beams 15. These plates serve both a reinforcing and decorative purpose. Grilles 19 are installed between each supporting steel column 11 and the wall of the building 17. The grilles 19 can be selected as storage partitions, New Year picture grilles, etc.

[0035] 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 supporting steel column 11 and the old building 17 may be adjusted when installing the supporting steel column 11. Therefore, in this solution, as shown in Figure 2, 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 members 6 for locking and fixing the base plate 1 and the mounting base are installed in the first adjustment slot and the second adjustment slot 5. The locking members 6 are high-strength bolts. A decorative protective cover 10 is installed on the side wall of the base plate 1. The decorative protective cover 10 can be made of decorative materials such as stone, which can provide both protection and decoration.

[0036] Secondly, to allow for a wider adjustment range of the mounting base while ensuring the supporting strength of the substrate 1, an independent auxiliary slot 20 is provided on the extension line of the second adjustment slot 5 on the substrate 1. This ensures that the substrate 1 remains intact between the second adjustment slot 5 and the auxiliary slot 20, guaranteeing its supporting strength. When the mounting base is adjusted to the right by a large distance, the two ends of the first adjustment slot can be placed at the second adjustment slot 5 and the auxiliary slot 20 respectively, and then secured with bolts.

[0037] Construction method: Connect the mounting base, base plate 1, and connecting steel parts 2 into one unit. Then, drill pile holes on the ground corresponding to the four connecting steel parts 2. Pour concrete into the pile holes and insert the connecting steel parts 2 on the base plate 1 into the concrete in the pile holes. After the concrete reaches the design strength, fit the supporting steel column 11 onto the connecting body 4 and connect and fix the two with bolts. Finally, install marble decorative protective covers 10 around the base plate 1. Fix the mounting plate 7 on the wall of the old building 17, and bolt the longitudinal beam 8 between the mounting plate and the supporting column to reinforce it. Bolt the transverse beam 15 between adjacent supporting steel columns 11 to reinforce it.

[0038] Example 2

[0039] Decorative support structures 18 are fitted with decorative eaves at each floor of the old building. Specifically, two reinforcing beams 15 are installed at each floor, spaced vertically, and connected by a grille 19, which serves both a reinforcement and decorative purpose. The decorative eaves 16 are installed at the uppermost reinforcing beam 15, protruding outward from the supporting steel column 11 in a direction away from the building structure 17. In this design, the decorative eaves 16 adopt an antique-style design, such as a hip roof, gable roof, or palace roof, making the renovated building facade more aesthetically pleasing.

[0040] Example 3

[0041] Due to a lack of management, residents of old buildings have arbitrarily erected temporary facilities on their rooftops. Because the shapes and materials are inconsistent with the architectural style, these structures appear out of place with the surrounding environment, negatively impacting the overall image of the town and streets. During the rooftop design process, some plans are abandoned due to concerns about the impact of new roofs on the load-bearing capacity of old buildings. However, for commercial streets with specific needs such as creating an antique architectural style, abandoning rooftops would significantly affect the overall aesthetic appeal of the building complex.

[0042] Based on this background, as shown in Figure 6, this embodiment designs a technical solution that can add a roof without burdening the load-bearing capacity of the old building 17. Specifically, a roof structure is detachably connected to the decorative support 18, which includes beam-column units and a top surface unit detachably installed on the beam-column units. The beam-column units include triangular frames 21 and roof beams 22. The three ends of the triangular frames 21 are detachably connected to the roof beams 22. Specifically, grooved connectors 12 are bolted to the opposite surfaces of two adjacent triangular frames 21. The two ends of the roof beams 22 are respectively fitted onto the grooved connectors 12 of the left and right triangular frames 21 and fixed by high-strength bolts.

[0043] In addition, a reinforcing beam 23 is horizontally installed in the middle of the tripod 21, forming a triangular cavity with the tripod 21, and a grid 19 is provided inside the triangular cavity. This arrangement not only enhances the stability of the tripod 21, but also improves the decorative appearance of the roof.

[0044] The top unit has a triangular cross-section and includes a roof 24 and an insulation board 25 located below the roof 24. The insulation board 25 is a conventional integrated insulation board 25, which has achieved the effect of thermal insulation for the building 17. Each edge of the top unit is detachably connected to a fascia board 26. Specifically, each fascia board 26 has a snap-fit ​​groove, into which the edges of the roof 24 and the insulation board 25 are snapped and fixed with bolts.

[0045] In this embodiment, the roof structure is detached from the original building and independently supported on the ground by decorative supports. Therefore, the roof structure in this solution will not pose a load-bearing risk to the original old building. At the same time, the roof structure in this solution can be redesigned with a new roof style according to new functional and aesthetic needs, such as an antique-style building, which greatly improves the overall aesthetics of the updated building complex.

[0046] The above descriptions are merely embodiments of this utility model. Commonly known technical solutions and / or characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application should be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
