Description

Technical Field

[0001] The present invention relates to a shock-absorbing support device, specifically a herringbone assembled combined energy-dissipating shock-absorbing support device, mainly applied to the energy dissipation and shock absorption of structures such as buildings, bridges, and railways, to dissipate unpredictable seismic energy, and belongs to the field of seismic resistance technology for building engineering. Background Art

[0002] In order to avoid or mitigate the impact of earthquake disasters on building structures, since the 1970s, people have gradually applied mild steel, viscous dampers, etc. to structural engineering such as buildings, bridges, and railways, using dampers to absorb unpredictable seismic energy.

[0003] With the increasing demand for the height, breadth, complexity of urban buildings and the energy dissipation and shock absorption capacity of buildings in the development of modern society, traditional single energy-dissipating shock-absorbing technologies have gradually been replaced by combined energy-dissipating shock-absorbing technologies. Since the combined energy-dissipating shock-absorbing technology has the advantages of two or more energy-dissipating shock-absorbing technologies, and the shock-absorbing design is more flexible and diverse, it is more suitable for the era requirements of modern urban development and can meet people's subjective requirements for buildings.

[0004] At the same time, due to the objective requirements of the times and people for buildings, the development of modern energy-dissipating shock-absorbing technologies requires the energy-dissipating shock-absorbing technologies to develop in the directions of having design flexibility, functional diversity, the shock-absorbing device can be industrially produced, the installation should be simple and fast, it should be convenient to monitor during use, and it should be able to be quickly replaced after damage.

[0005] A utility model patent with the publication number CN2725397Y proposes a small eight-shaped crank brace type frame. The fixed connections of each bolt of the small eight-shaped crank brace type frame are all rigid fixed connections. When the building is subjected to horizontal forces, the connection nodes between the support and the building are easily damaged. After damage, the replacement is cumbersome, increasing the labor intensity of construction workers and not achieving a good shock-absorbing effect at the same time. More importantly, there are greater potential safety hazards; the damper of the small eight-shaped crank brace type frame is arranged at the corner position of the building frame, and the displacement stroke of the damper deformation is restricted, and the advantages of the large stroke of the damper cannot be effectively exerted. The building installed with the small eight-shaped crank brace type frame cannot effectively resist large seismic actions, which is not conducive to the energy dissipation and shock absorption of the building; at the same time, the small eight-shaped crank brace type frame only arranges one type of damper and belongs to a single-function shock-absorbing device with a single function.

[0006] Therefore, the key to solving the above technical problems is to develop a herringbone assembled combined energy-dissipating shock-absorbing support device with flexible design, diverse functions, simple structure, fully assembled, easy installation, easy replacement after earthquake damage, small installation difficulty, low cost, and good implementation effect.

Among them, an injection molding layer, a rust-proof layer and a waterproof layer are sequentially provided on the outer surfaces of the main support member (1), the secondary support member (2) and the viscous damper (3) from the inside to the outside.

[0020] The working principle is as follows: Before using a herringbone assembled combined energy dissipation and vibration reduction support device with the above design structure, it is necessary to manufacture and install the support device with the design structure of the present invention as a standby.

[0021] For the convenience of understanding, it should be noted here that in the present invention, the building (5) includes building frame columns (51) and building frame beams (52).

[0056] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

A secondary support member 2 is movably installed on one side of any end of the main support member 1, and a viscous damper 3 is movably installed on the other side of any end of the main support member 1.

[0058] Furthermore, one end of the main support member 1 is provided with a connecting member 11, and a connection hole penetrating the front and back surfaces is formed on the connecting member 11; mounting seats 12 are respectively arranged on the upper and lower sides of the other end of the main support member 1.

[0060] Specifically, one end of the main support member 1 is connected to the building 5 through a fixed seat 4, and the other end is connected to the secondary support member 2 and the viscous damper 3 through a bolt assembly.

[0061] In the present invention, the main support member 1 is an overall straight-shaped steel girder or square steel; the secondary support member 2 is a curved soft steel beam. Among them, the main support member 1 has a large stiffness.

[0068] In the present invention, a connection node is welded to the end of the viscous damper 3, and the cross-section can be circular or square, capable of undergoing slow axial tensile and compressive deformations. After being subjected to seismic forces, it can undergo axial telescopic deformations to dissipate seismic energy.

[0073] In the present invention, any mentioned movable installation or movable connection refers to hinge connection, screw connection, bayonet connection, plug-in connection, or connection through a bolt assembly.

[0074] In summary, a more specific embodiment of the present invention is as follows:

[0075] Before using a herringbone assembled combined energy dissipation and seismic reduction support device with the above design structure, it is necessary to fabricate and install the support device with the design structure of the present invention for standby.

[0076] For the sake of easy understanding, it should be noted here that in the present invention, the building 5 includes building frame columns 51 and building frame beams 52.

[0077] During fabrication, the present invention can be processed and manufactured in a factory. The four components constituting the present invention, namely the main support member 1, the secondary support member 2, the viscous damper 3, and the fixed seat 4, are all fabricated according to the model sizes required by the actual construction. After passing the quality inspection, the construction workers only need to transport them to the designated construction site for installation, thus realizing the process of assembled manufacturing, transportation, and production.

[0078] During installation, the construction workers only need to detachably install the secondary support member 2 and the viscous damper 3 on the above-mentioned already fabricated main support member 1 through bolt assemblies. During installation, one end of the secondary support member 2 is detachably connected to the mounting seat 12 at the upper end of the main support member 1 through a bolt assembly, and one end of the viscous damper 3 is detachably connected to the mounting seat 12 at the lower end of the main support member 1 through a bolt assembly, thus completing the installation of the present invention. After the installation is completed, it can be put into normal use, and the state diagrams of the herringbone assembled combined energy dissipation and shock absorption support device under the action of horizontal forces, including horizontal seismic action or wind load, when stressed and unstressed, are as shown in Figures 13 to 15 the figure.

[0079] Before use, the construction workers only need to carry the present invention to the designated construction site for fixed installation. During fixed installation, the construction workers need to pre-embed the three fixed seats 4 of the present invention into the building 5 according to the construction standard requirements. These three fixed seats 4 are respectively pre-embedded at any triangular positions of the building 5, and the fixed seat 4 is located at the connection node of the building frame column 51 and the building frame beam 52.

[0080] During use, the construction workers only need to fix one end of the above-mentioned installed main support member 1 to the three fixed seats 4 by high-strength bolts, and fasten the end with a fastening nut to form an integral structure. For the installation of the other end of the main support member 1, first, the other end of the secondary support member 2 is detachably connected to the fixed seat 4 through a bolt assembly, and then the other end of the viscous damper 3 is detachably connected to the fixed seat 4 through a bolt assembly. Thus, a herringbone assembled combined energy dissipation and shock absorption support device of the present invention is installed in the reinforced concrete frame structure or steel frame structure, and then concrete is poured, so as to be better applied to the energy dissipation and shock absorption of the reinforced concrete and steel frame structures.

[0081] Finally, over time, when the present invention is damaged after long-term use, it needs to be demolished. During demolition, only the components of the damaged herringbone assembled combined energy dissipation and shock absorption support device need to be removed by removing the bolts and new components need to be replaced. The undamaged components can continue to be used.

[0082] During the above entire implementation operation process, the following construction preparations need to be made:

[0083] First, organize the construction management personnel and professional construction teams of each type of work to review the detailed design drawings of the shock absorption device, and familiarize with and master the details in the drawings. Then, arrange for the shock absorption device and related connecting components to enter the site and conduct re-inspection to be qualified, and prepare all the corresponding equipment and tools for transportation, hoisting, and installation. The load-bearing capacity of the machinery should meet the construction requirements. Then, conduct on-site dimension verification before installing each component. If any discrepancy is found with the drawings, promptly report it to the designer and make adjustments.

[0084] Second, loft, process, and fabricate the fixed seat 4. According to the large-scale drawings of the fixed seat 4 with different specifications provided by the design institute, the fixed seat 4 can be processed and customized in the factory or welded on-site. The fixed seat 4 is welded by a support plate 41, a mounting plate 42, and an anchoring member 43. The anchoring member 43 can greatly improve the bonding and wrapping force between the fixed seat 4 and the concrete. The welding positions should be strictly constructed according to the drawings, precise and reliable. When welding, the welds should be smooth without welding defects such as air holes and slag inclusions. If any defects are found, they should be repaired promptly.

[0085] Third, install the fixed seat 4. After the formwork of the beam, slab, and column is set up, use a tower crane to lift the metal fixed seat 4 to the corresponding embedded position of the floor structure. It is required that all components must be firmly tied up, and a special person should be arranged to command during the lifting process. To ensure that the fixed seat 4 is accurately and smoothly placed into the beam-column joint, after the formwork of the beam, slab, and column is set up, mark the installation position of the fixed seat 4 according to the detailed design drawings. After the main reinforcement bars of the beam, slab, and column are placed, lift the main reinforcement bars of the beam, and arrange a special person to promptly and accurately place the fixed seat 4 at the corresponding position of the beam-column joint and make temporary fixation. After the steel bars are tied up, the position of the fixed seat 4 should be re-verified again, and the centers of the upper and lower fixed seats 4 should be aligned to ensure that the chevron-shaped assembled combined energy dissipation and shock absorption support is installed in the vertical plane. When installing the fixed seat 4, the installation error of the fixed seat 4 should be less than 10 mm. After confirming that the installation is completed and qualified, the concrete can be poured.

[0086] Fourth, pour the concrete of the beam, slab, and column. When pouring the concrete, the position of the fixed seat 4 should be vibrated densely, and a steel rod can be used to assist in vibrating. Do not touch the fixed seat 4 during vibration. Before the initial setting after pouring is completed, use a long wooden float to finish the surface treatment, and at the same time, conduct plastic film moisture conservation in a timely manner within 12 hours. The maintenance period should be no less than 7 days and nights.

[0087] Fifth, installation and fixation of the present invention: After using a hoisting device to lift the corresponding support frame to a suitable installation position, construct according to the corresponding detailed design drawings. To ensure that the support is in the vertical plane, a positioning line should be drawn first before installation. Then, use a manual hoist to lift the support with the help of the main structure, adjust the positions up, down, left, and right to the design position, and use high-strength bolts to connect the main support member 1, the secondary support member 2, and the viscous damper 3 to the fixed seat 4. In this implementation process, the present invention can be transported, hoisted, and installed after being assembled as a whole, or can be transported, hoisted, and installed piece by piece.

[0088] Six is the connection node detection: After the construction of the entire assembled combined energy dissipation and seismic reduction support is completed, the reliability of the connection between the assembled combined energy dissipation and seismic reduction support components and the structure and the welds of the connection nodes shall be detected. For the first and second grade welds that are required to be fully penetrated by design, ultrasonic flaw detection shall be used to inspect the internal defects. When ultrasonic flaw detection cannot judge the defects, radiographic flaw detection shall be used. The test results shall meet the specification requirements;

[0089] Seven is the anti-corrosion and fire protection treatment. The welds shall be ground to remove all welding slag. When grinding, flush grinding shall be carried out, and the joint part shall be in a smooth state with the base metal, and there shall be no unevenness; Then, repair the damaged parts of the paint. The anti-corrosion of the joint connection components shall use epoxy zinc-rich paint, and the film thickness shall not be less than 12mm. The on-site welded parts shall be painted as soon as possible after welding; Finally, after the acceptance of the anti-corrosion construction, the fire protection construction shall be carried out according to the design requirements;

[0090] Eight is the masonry of the infill wall at the support connection part. When constructing the horizontal tie bars and structural columns of the wall, use connection clips to connect with the tie bars on both sides of the support to ensure the continuity of the tie bars; When plastering the wall, a layer of galvanized wire mesh shall be made at the support part. The galvanized wire mesh shall be fixed to the wall with galvanized wire and nail guns to ensure that the wall plastering does not crack.

The energy dissipation damage position of the support can be controlled. Due to the existence of the viscous damper, the damage of the curved mild steel support member can be slowed down, so that the curved mild steel support member has a large deformation performance, strong ability to dissipate seismic forces, and has greater energy dissipation capacity and design flexibility compared with a single mild steel seismic reduction support. Through reasonable design, it can be better applied to the energy dissipation and seismic reduction of reinforced concrete and steel frame structures;

[0096] 6. The present invention not only improves the seismic fortification intensity of super high-rise residential buildings, ensures that the building does not collapse under the action of large earthquakes and guarantees the safety of construction workers, but also effectively protects the building structure and interior decoration, improves the seismic safety level of the building within the design service life, and minimizes the losses of the building during major earthquakes;

[0098] 8. The components of the present invention are symmetric as a whole, with reasonable weights, facilitating hoisting and installation; since the support member is arc-shaped, it can not only transfer the bending moment between the precast wall and the precast coupling beam, and at the same time, the arc has a certain deformation ability, and can dissipate seismic energy through deformation during earthquakes, improving the structural safety. At the same time, it can also alleviate the inclination angle generated when the building wall twists and shakes during earthquakes. Through the above structure, during earthquakes, the continuous vibration damage of aftershocks to the building structure can be reduced;

[0099] 9. The present invention can select different working states according to the change of external forces, making full use of the energy dissipation effect of the viscoelastic damper when the external force is small to supplement the support member 1, that is, the defect that the mild steel cannot dissipate energy when the external force is small; it also makes full use of the energy dissipation effect of the support member 1 when the external force is large to supplement the defect that the viscoelastic damper loses the energy dissipation effect when the external force is large; when the external force is at an intermediate value, it can gradually change the main energy dissipation component, maintain the stability of replacement, yield in stages, effectively reduce the vibration response of the building structure, and improve the safety performance of the main building structure;

[0100] 10. The assembled rigid joint of the present invention has the characteristics of strong energy dissipation ability, good ductility, good shock absorption effect, and can avoid the collision of beams and columns under large earthquakes; and the construction is simple, easy to implement, with low cost, occupying a small building space and not affecting the use efficiency of the building space;

[0101] 11. Compared with the traditional one, the structure of the present invention is relatively simple, reasonable, economical and durable, especially suitable for concrete frame structures similar to this project, with stable seismic performance and convenient post-earthquake treatment; the shock absorption mechanism is clear and the effect is remarkable, and the application scope is not limited by the building height and plane layout form;

[0102] 12. Through optimized design, the present invention adopts an energy dissipation and shock absorption structure, improves the seismic capacity of the building, and has the characteristics of convenient structure installation, simple and fast construction, and good seismic effect;

[0103] 13. The present invention can completely carry out dry construction operations, making the working surface cleaner, effectively avoiding construction safety problems. With this structure, the requirements for construction technology are not high, and only simple operations are needed to achieve the reinforcement effect. The materials used are easy to collect and the structural configuration is simple, and its bearing capacity and seismic performance can be guaranteed.
