Description

Technical Field

[0001] The invention belongs to the field of building storey-adding, reconstruction and reinforcement measures, and in particular relates to a shear and tension-compression energy-absorbing support after a building storey is added. Background Art

[0002] my country has a large population and very limited land resources. Therefore, saving land is an urgent problem to be solved; at the same time, the floor-adding and renovation project has a very significant effect on saving land, reducing project costs and many other aspects. In general, the floor-adding and renovation of houses can be divided into the floor-adding and renovation of civil and industrial houses. Among them, civil buildings such as residential buildings, office buildings, hospitals, hotels, shops, etc. are relatively large and wide-ranging buildings. According to my country's national conditions and national policies, it is not allowed to occupy good land to build houses. It is determined that my country should renovate and utilize low-rise or multi-story houses as much as possible, and cannot adopt the policy of completely demolishing and rebuilding. According to the survey, there are a large number of low-rise or multi-story civil buildings in towns and cities, which cannot be stopped from use, and urgently need to expand the use area. Adding floors in combination with improving the use function of the house or overhauling it is an important way to transform and utilize low-rise or multi-story houses into multi-story or medium-high-rise houses. Some of these buildings were not seismically fortified in the past or the fortification standards were low. Such buildings can be reinforced and renovated to achieve the purpose of improving the use function of the house, seismic reinforcement and structural energy dissipation and shock absorption, ensuring that the connection is sufficiently stable while improving the seismic performance. Earthquake disasters are sudden and destructive, seriously threatening the safety of human life and property. Nearly a thousand destructive earthquakes occur in the world every year. A major earthquake can cause economic losses of hundreds of billions of dollars and lead to the death or serious disability of hundreds of thousands of people. my country is located in the two most active seismic belts in the world and is one of the countries most severely affected by earthquake disasters. The casualties caused by earthquakes rank first in the world, and the economic losses are also huge. The poor seismic resistance of the structural connection of the added-story building during an earthquake can easily lead to a large amount of damage and collapse, causing serious damage or even collapse of the main load-bearing structure, which is the direct cause of the earthquake disaster. In order to avoid the above disasters, people must control the seismic response of the structure of the multi-storey building and eliminate the poor seismic resistance, so that it has sufficient rigidity to meet the use requirements in light wind or small earthquake. When a strong earthquake or strong wind occurs, the structure has a certain elastic effect and produces greater damping, which can consume a large amount of seismic or wind vibration energy input to the structure, so that the structural kinetic energy or elastic potential energy is converted into heat energy and dissipated, protecting the structure from damage in strong earthquakes or strong winds. The structure of multi-storey buildings currently developed has poor seismic resistance, so the manufacturing process and energy consumption capacity still need to be further improved. Summary of the invention

[0003] In order to solve the above-mentioned technical problems, the present invention provides a shear and tension-compression energy absorption support after adding floors to a building, which can well play the role of shear and tension-compression energy absorption support after adding floors to a building, and will not cause collision or tensile damage to the original building and the additional building when an earthquake occurs, thereby improving the seismic resistance and safety performance of the original building after adding floors. At the same time, as a protective measure when a collision occurs, the low cost is a significant advantage.

[0004] In order to achieve the above object, the technical solution adopted by the present invention is:

[0005] A shear and tension-compression energy-absorbing support after adding floors to a building, comprising an original building, an additional building, a connecting plate A, a main support energy-absorbing steel plate A, a main support energy-absorbing steel plate B, an internal circular hole, an energy-absorbing rib, a welded connection end, a shear energy-absorbing support steel plate, a connecting plate B, a connecting piece, a shear energy-absorbing support device, a tension-compression energy-absorbing support steel plate, a welded connecting plate, and a lightweight shear energy-absorbing material. A plurality of main support energy-absorbing steel plates A and main support energy-absorbing steel plates B are arranged in the gap between the original building and the additional building. The main support energy-absorbing steel plate A is arranged at the upper and lower ends of the gap. One end of the main support energy-absorbing steel plate A is connected to the connecting plate A, and the other end is connected to the connecting plate. The main support energy-absorbing steel plate B is connected, the main support energy-absorbing steel plate B is arranged between the main support energy-absorbing steel plates A, and the two ends of the main support energy-absorbing steel plate B are respectively connected to the connecting plate A, and the connecting plate A and the connecting plate B are fixed to the original building and the additional building by connecting parts; shear energy-absorbing support devices are arranged at the connection nodes between the connecting plate A and the main support energy-absorbing steel plate A and the main support energy-absorbing steel plate B, and the shear energy-absorbing support devices are surrounded by welded connecting plates and shear energy-absorbing support steel plates, and the interior is filled with lightweight shear energy-absorbing materials; tensile and compressive energy-absorbing support steel plates are arranged between the main support energy-absorbing steel plate A and the main support energy-absorbing steel plate B, and the adjacent main support energy-absorbing steel plates B;

[0006] A plurality of internal circular holes are arranged in the tensile and compressive energy-absorbing steel plate, the main support energy-absorbing steel plate A, the main support energy-absorbing steel plate B, and the shear energy-absorbing steel plate. Energy-absorbing ribs are arranged between adjacent internal circular holes. A welding connection end is arranged at one end of the main support energy-absorbing steel plate A, and welding connection ends are arranged at both ends of the main support energy-absorbing steel plate B.

[0007] The welding connection plate is welded to the connection plate A and the welding connection end respectively.

[0008] Furthermore, the main support energy-absorbing steel plate A, the main support energy-absorbing steel plate B, the shear energy-absorbing support steel plate, and the tension-compression energy-absorbing support steel plate are low-yield point energy-absorbing steel plates.

[0009] Furthermore, the lightweight shear energy dissipation material is made of foamed aluminum.

[0010] Furthermore, the connecting plate A, the main support energy-absorbing steel plate A, the main support energy-absorbing steel plate B, the shear energy-absorbing support steel plate, the connecting plate B, the connecting piece, the tensile and compressive energy-absorbing support steel plate, and the welded connecting plate are treated with galvanizing for corrosion protection.

[0011] Furthermore, the upper and lower ends of the tensile and compressive energy-absorbing support steel plate are connected to the energy-absorbing ribs of the main support energy-absorbing steel plate A and the main support energy-absorbing steel plate B.

[0012] Advantages and effects of the present invention:

[0013] The beneficial effects of the present invention are simple construction, low construction cost, and very convenient industrial disassembly. The prefabricated components are easy to produce and install, which is conducive to promoting the process of industrialization. When adding floors to the original building, the original building and the additional building are adjacent to each other. The device plays a good role in shearing and tension and compression energy-absorbing support after the building is added. When relative tension and compression occur, the main support energy-absorbing steel plate can consume energy and squeeze the tension and compression energy-absorbing support steel plate to consume energy. When relative shear occurs, the main support energy-absorbing steel plate can squeeze the shear energy-absorbing support device to consume energy. The shear energy-absorbing support steel plate can play an energy-absorbing support role, which significantly improves the energy-absorbing efficiency of the structure. A plurality of main support energy-absorbing steel plates are used as connections, and a shear energy-absorbing support device and a tension and compression energy-absorbing support steel plate are set as auxiliary supports to ensure the seismic energy absorption of the structure while giving it a certain rigidity. The original building and the additional building can work together to improve the seismic performance and safety performance of the original building after adding floors, and the construction cost is low.
