Description

Technical Field

[0001] This application relates to the field of building structure replacement, and in particular to a recyclable column replacement device. Background Technology

[0002] In the construction field, with urban development and the updating of building functions, the demand for the renovation and reinforcement of existing building structures is increasing. Optimizing and adjusting building structures can improve the safety, usability, and durability of buildings, meeting the usage requirements of different periods. This is of great significance for making full use of existing building resources and reducing the environmental impact of new buildings. At the same time, reasonable building renovations can also help reduce construction costs and improve the economic efficiency of buildings. With the continuous advancement of building technology, people are also placing higher demands on the efficiency and quality of building structural renovations.

[0003] In the structural renovation of existing buildings, the common approach to column replacement has historically been to directly demolish the old columns and cast new ones. This method requires extensive formwork and support systems, making the construction process quite complex. Another method involves using temporary support structures to transfer the load of the superstructure to these temporary supports before removing the old columns and installing new ones. However, this method requires precise calculations of the temporary supports' load-bearing capacity, and both the installation and removal of these supports are time-consuming and labor-intensive. Additionally, a method of overall jacking is used, where the entire superstructure is lifted to a certain height before column replacement; however, this method demands advanced jacking equipment and technical expertise.

[0004] Existing column replacement methods have several drawbacks. Directly removing the old column and recasting a new one results in a long construction period and significantly impacts the building's usability. Using temporary support structures is complex in its construction and dismantling, and the calculation of load-bearing capacity carries a risk of error. Overall jacking is costly and technically challenging, making it unsuitable for most column replacement projects. Summary of the Invention

[0005] The purpose of this application is to overcome the above-mentioned technical problems and provide a recyclable column replacement device. To achieve the above objectives, the present invention adopts the following technical solution: a recyclable column replacement device, comprising a non-replacement column and a column to be replaced, wherein an upper support beam is provided above the column to be replaced, the upper support beam is provided on both sides of the non-replacement column, and a plurality of screws are provided inside the upper support beam, the screws passing through the upper support beam and the non-replacement column and extending to both sides of the upper support beam; a lower support beam is provided below the column to be replaced, the lower support beam is provided on both sides of the non-replacement column, and a plurality of screws are provided inside the lower support beam, the screws passing through the lower support beam and the non-replacement column and extending to both sides of the lower support beam; a replacement steel column is provided at the top of the lower support beam, and a jack is provided at the top of the replacement steel column, the jack extending to the bottom of the upper support beam.

[0006] Preferably, the screw is a high-strength screw with full threading.

[0007] Preferably, steel pads are provided at both ends of the screw extending from the upper and lower support beams.

[0008] Preferably, the supporting steel column is configured as a multi-section hollow structure.

[0009] Preferably, an end sealing plate is provided between the supporting steel column and the jack.

[0010] Preferably, the upper and lower support beams are provided with stiffening ribs.

[0011] Preferably, the surfaces of the supporting steel column, the upper supporting beam, and the lower supporting beam are all coated with an anti-corrosion coating.

[0012] In summary, this application includes at least one of the following beneficial technical effects: 1. By using upper and lower beam replacement, bolts, steel column replacement and jacks, the method of directly demolishing the old column and re-casting the new column can be avoided, reducing the workload of building formwork and support system. The device can be quickly and completely disassembled and reused, shortening the construction cycle and reducing the impact on the normal use of the building. 2. It eliminates the need for temporary support structures to transfer the load from the superstructure, avoiding the complexity of temporary support construction and dismantling processes, as well as the risk of errors in load-bearing capacity calculations. It is economical and environmentally friendly, reduces construction material costs, and conforms to the concept of green building. 3. The column replacement method does not use the overall jacking method, which reduces costs and technical difficulty. It can be quickly adjusted, and the replacement height can be flexibly adjusted by segmented steel columns and jacks, making it suitable for most column replacement projects.

[0016] The technical solutions in the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. The described embodiments are only possible technical implementations of the present invention, but are not limited thereto. Other embodiments obtained by those skilled in the art in conjunction with the embodiments of the present invention without creative effort are also within the protection scope of the present invention.

[0017] This application mainly adopts the method of setting up replacement beams, replacement steel columns and jacks for column replacement, which achieves the effects of simplifying the column replacement construction process, reducing costs and being recyclable. The following is a further detailed description of this application.

[0018] Example 1 The recyclable column replacement device provided in this application includes a non-replacement column 10, a column to be replaced 8, an upper support beam 5, a lower support beam 3, screws 1, a replacement steel column 7, and jacks 3. The upper support beam 5 is positioned above the column to be replaced 8, located on both sides of the non-replacement column 10. Several screws 1 are installed within the upper support beam 5, penetrating both the upper support beam 5 and the non-replacement column 10 and extending to both sides of the upper support beam 5. A lower support beam 6 is positioned below the column to be replaced 8, located on both sides of the non-replacement column 10. Several screws 1 are installed within the lower support beam 6, penetrating both the lower support beam 6 and the non-replacement column 10 and extending to both sides of the lower support beam 6. A replacement steel column 7 is positioned at the top of the lower support beam 6, and a jack 3 is positioned at the top of the replacement steel column 7, extending to the bottom of the upper support beam 5. This achieves the effect of transferring the load of the upper structure, facilitating column replacement, and enabling the device to be recycled. This is because the upper support beam 5 and the lower support beam 6 are fixed to the non-replacement column 10 by the screw 1, which can stably bear the load of the upper structure. The support steel column 7 and the jack 3 work together to transfer the load from the column to be replaced 8, thereby realizing the replacement of the column. The device can be reused after it is removed.

[0019] Specifically, the upper support beam 5 includes a beam body and screw rods 1. The beam body is usually made of steel or reinforced concrete, and is generally rectangular in shape. It has a certain strength and rigidity to withstand the load of the superstructure. The beam body is installed on both sides of the non-replacement column 10 and above the column to be replaced 8, and is tightly fitted to the non-replacement column 10. The screw rod 1 is a high-strength screw rod with full threading. This type of screw rod has high strength and can provide reliable connection force. The screw rod 1 passes through the beam body and the non-replacement column 10 and extends to both sides of the beam body. Steel pads 2 are provided at both ends of the extension. The steel pads 2 are generally square or round steel plates. Their function is to increase the contact area between the screw rod 1 and the beam body and the non-replacement column 10, distribute pressure, and prevent excessive local stress. The screw rod 1 is connected to the beam body and the non-replacement column 10 by threads. During installation, the screw rod 1 is first passed through the pre-drilled holes in the beam body and the non-replacement column 10, and then the steel pads 2 are installed at both ends and the nuts are tightened to ensure a firm connection. The beam body of the upper support beam 5 and the screw rod 1 are combined together to transfer the load of the upper structure to the non-replacement column 10, and at the same time work together with other components to realize the function of column replacement.

[0020] Specifically, the lower support beam 6 includes a beam body and screw rods 1. The beam body of the lower support beam 6 is similar in structure to that of the upper support beam 5, also made of steel or reinforced concrete, and is rectangular in shape. It is installed on both sides of the non-replacement column 10 and located below the column to be replaced 8. The screw rods 1 are also high-strength, fully threaded screw rods, penetrating the beam body and extending to both sides of the non-replacement column 10, with steel pads 2 installed at both ends. The connection method between the screw rods 1 and the beam body and non-replacement column 10 is the same as that of the screw rods 1 in the upper support beam 5, through threaded connection and using steel pads 2 to distribute pressure. The function of the lower support beam 6 is to cooperate with the upper support beam 5 to jointly bear the load of the superstructure, providing stable support for column replacement.

[0021] Specifically, the supporting steel column 7 is a multi-segment hollow structure. The supporting steel column 7 is generally made of steel, with each segment being a hollow cylinder. This hollow structure reduces the weight of the steel column while ensuring sufficient strength, and also meets the requirements of different replacement heights. The supporting steel column 7 is installed on top of the lower supporting beam 6 and fixed to the lower supporting beam 6 by bolts or other means. An end sealing plate 4 is installed between the supporting steel column 7 and the jack 3. The end sealing plate 4 is generally a circular steel plate, and its function is to ensure a tight connection between the supporting steel column 7 and the jack 3, allowing the jack 3 to stably transfer the load to the supporting steel column 7. The multi-segment hollow supporting steel column 7 can be combined according to actual needs, facilitating installation and disassembly, and can be reused in different column replacement projects.

[0022] Specifically, jack 3 is typically a hydraulic jack, which has a large lifting force. Jack 3 is installed on top of the supporting steel column 7, extending to the bottom of the upper supporting beam 5. When column replacement is required, the jack is operated to provide an upward force to the upper supporting beam 5, thereby transferring the load of the superstructure from the column to be replaced 8 to the support system composed of the supporting steel column 7 and jack 3.

[0023] In addition, stiffening ribs 9 are installed inside the upper support beam 5 and the lower support beam 6. The stiffening ribs 9 are generally steel plates, and their shape can be triangular or rectangular. They are installed inside the beam body and fixed to the beam body by welding or bolting. The function of the stiffening ribs 9 is to enhance the strength and rigidity of the beam body and improve its load-bearing capacity. The surfaces of the support steel column 7, the upper support beam 5, and the lower support beam 6 are all coated with an anti-corrosion coating. The anti-corrosion coating can be made of materials such as rust-proof paint, and its function is to prevent these components from rusting and corroding, extending the service life of the device.

[0024] The implementation principle of this embodiment is as follows: The reusable column replacement device of this embodiment, through the combination of components such as the upper support beam 5, the lower support beam 6, the screw rod 1, the support steel column 7, and the jack 3, can stably transfer the load of the superstructure from the column to be replaced 8 to the support system, thereby facilitating column replacement. The fully threaded high-strength screw rod 1 and the steel pad 2 ensure the reliability of the connection, the multi-section hollow support steel column 7 facilitates installation and disassembly, the end sealing plate 4 ensures a tight connection between the jack 3 and the support steel column 7, the stiffening rib 9 enhances the load-bearing capacity of the support beam, and the anti-corrosion coating extends the service life of the device. Moreover, the device can be reused in other column replacement projects after dismantling, reducing costs and improving resource utilization. Compared with existing column replacement methods, the construction process is simpler, the impact on the normal use of the building is smaller, and it is suitable for most column replacement projects.

[0025] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
