Description

Technical Field

[0001] The invention belongs to the field of building storey-adding, reconstruction and reinforcement measures, and in particular relates to an anti-collision and shock-absorbing reinforcement connection device for adding stores to an existing building. Background Art

[0002] In general, the addition and renovation of houses can be divided into the addition 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 widespread. 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 the improvement of house use functions or major repairs is an important way to transform and utilize low-rise or multi-story houses into multi-story, medium and 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. 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 an anti-collision and shock-absorbing reinforced connection device for adding floors to existing buildings, which adopts external and internal connecting energy-absorbing plates as connections and arranges multiple energy-absorbing steel plates at the nodes as supports to ensure the seismic energy absorption of the structure while giving it a certain rigidity, thereby ensuring the enhanced connection effect without bringing excessive load pressure to the building.

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

[0005] A collision-proof and shock-absorbing reinforcement connection device for adding floors to an existing building, comprising an original building, an additional building, a connection plate, an external connection energy-absorbing plate, an internal connection energy-absorbing plate, an internal circular hole, an energy-absorbing rib, a connection end, an energy-absorbing support steel plate, a tension and compression rod, a connection piece, a node angle steel energy-absorbing auxiliary support, a shear energy-absorbing main support steel plate, a connection right-angle plate, an energy-absorbing material, a hydraulic energy-absorbing device, a high-strength spring, and a buffer rubber block. An collision-proof and shock-absorbing reinforcement connection device surrounded by a connection plate and an external connection energy-absorbing plate is arranged between the original building and the additional building. Shear energy-absorbing main support steel plates are arranged on the inner sides of the four corners of the collision-proof and shock-absorbing reinforcement connection device, and node angle steel energy-absorbing auxiliary supports are arranged on the outer sides of the four corners. Adjacent connection plates and external connection energy-absorbing plates are connected by tension and compression rods. An energy-absorbing structure surrounded by the internal connection energy-absorbing plates is arranged at the center of the collision-proof and shock-absorbing reinforcement connection device. The four sides of the energy-absorbing structure are provided with a plurality of shear energy-absorbing main support steel plates. The angle is welded with the tension and compression rods, and the interior of the energy-absorbing structure is provided with a component formed by connecting a number of high-strength springs and buffer rubber blocks. The high-strength springs at the left and right ends of the component are fixedly connected to the built-in connecting energy-absorbing plates. Energy-absorbing materials are arranged in the internal cavity of the anti-collision and shock-absorbing strengthening connection device, and the connecting plate is connected to the original building and the additional building by connecting parts; a number of hydraulic energy-absorbing devices are arranged on the tension and compression rods; the node angle steel energy-absorbing auxiliary support is surrounded by an energy-absorbing support steel plate and a connecting right-angle plate, and the connecting right-angle plate is connected to the original building and the additional building by connecting parts; connecting ends are arranged on the left and right ends of the energy-absorbing support steel plate and the external connecting energy-absorbing plate; the connecting end connecting the right-angle plate and the energy-absorbing support steel plate is connected by welding; the energy-absorbing support steel plate, the external connecting energy-absorbing plate, the built-in connecting energy-absorbing plate, and the shear energy-absorbing main support steel plate are all provided with a number of internal circular holes, and energy-absorbing ribs are arranged between the internal circular holes.

[0006] Furthermore, the external connection energy-absorbing plate, the internal connection energy-absorbing plate, the energy-absorbing support steel plate, and the shear energy-absorbing main support steel plate are made of low-yield point energy-absorbing steel plates.

[0007] Furthermore, the energy dissipation material is made of high damping rubber.

[0008] Furthermore, the connection plates, external connection energy-absorbing plates, internal connection energy-absorbing plates, connection pieces, node angle steel energy-absorbing auxiliary supports, and shear energy-absorbing main support steel plates are treated with galvanizing for corrosion protection.

[0009] The advantages of the present invention are:

[0010] The beneficial effects of the present invention are simple construction, low construction cost, very convenient industrial disassembly, and prefabricated components are easy to produce and install, which is conducive to promoting the process of industrialization. The device plays the role of anti-collision and shock absorption, anti-shear and strengthening connection after the building is added. When tension and compression displacement occurs, the internal and external connection energy-absorbing plates consume energy. When shear displacement occurs, the node angle steel energy-consuming auxiliary support, the shear energy-consuming main support steel plate, and the hydraulic energy-absorbing device can play the role of energy-consuming support. The structural design of multiple energy-consuming steel plates and energy-consuming materials extrusion significantly improves the energy consumption efficiency. The external and internal connection energy-consuming plates are used as connections and multiple energy-consuming steel plates are set at the nodes as supports to ensure the seismic energy consumption of the structure while giving it a certain rigidity. When an earthquake comes, the original building and the additional building will not be damaged by collision or pulling out, etc., and the original building and the additional building can work together to improve the seismic performance and safety performance of the original building after the addition of floors. It can provide a strong support for the original building and the additional building, and not bring excessive load pressure to the building while ensuring the strengthening effect.
