Description

Technical Field

[0001] The invention relates to the technical field of structural engineering, and in particular to a sliding energy-consuming node between an additional elevator module and an existing structure and a building. Background Art

[0002] At present, there are a large number of buildings without elevators in my country. With the development of the economy, the people's growing demand for the convenience of going up and down stairs in buildings is in conflict with the current situation that a large number of buildings do not have elevators. Adding elevators to existing buildings has an important practical role, and the node where the elevator and the building are connected is an important technical difficulty in adding elevators to existing buildings under the premise of ensuring structural safety, economy and durability. The existing technology has the following deficiencies:

[0003] (1) Traditional connection nodes and construction methods have disadvantages such as complex on-site installation and adverse effects on the safety of the original structure after installation.

[0004] (2) Rigid nodes are often used to connect the traditional elevator to the original structure, which needs to be designed separately and the impact of the elevator on the performance of the original structure needs to be verified. When encountering earthquakes, traditional nodes cannot effectively dissipate energy, and when there is a settlement difference between the elevator and the original structure, traditional rigid nodes will generate additional bending moments, which will have an adverse effect on the structure.

[0005] (3) Traditional construction methods have a significant impact on the original structure and construction is more difficult. Summary of the invention

[0006] The object of the present invention is to provide a method for adding a sliding energy dissipation node between an elevator module and an existing structure to solve at least one technical problem existing in the prior art.

[0007] In order to solve the above technical problems, the present invention provides a sliding energy dissipation node between an additional elevator module and an existing structure, comprising a connecting beam, a T-shaped plate and a connecting plate;

[0008] The connecting plate includes a bottom plate and a side plate that are integrally connected;

[0009] The bottom plate is arranged vertically with the side plate;

[0010] The T-shaped plate comprises an upper plate and a lower plate which are integrally connected;

[0011] The upper plate is arranged vertically with respect to the lower plate;

[0012] A first connecting hole and a second connecting hole are respectively provided at relative positions of the lower plate and the side plate;

[0013] Connecting the connecting plate to the T-shaped plate by passing a pin through the first connecting hole and the second connecting hole;

[0015] The connecting beam is provided with a fourth connecting hole;

[0016] The upper plate is connected to the connecting beam by fasteners passing through the third connecting hole and the fourth connecting hole.

[0017] Furthermore, the side panels are two or more;

[0018] The lower plate is provided as one or more;

[0019] The spacing between the side panels is greater than or equal to the thickness of the side panels;

[0020] The lower plate is inserted into and connected to the gaps between the side plates.

[0021] Preferably, the third connection hole and the fourth connection hole are in the shape of long strips and are perpendicular to each other.

[0022] Preferably, the third connection holes are multiple in number and arranged in parallel;

[0023] The fourth connection holes are multiple in number and arranged parallel to each other.

[0024] Furthermore, a pad is provided between the connecting beam and the T-shaped plate;

[0025] The backing plate is provided with a fifth connection hole, the position of which corresponds to the positions of the third connection hole and the fourth connection hole.

[0026] Furthermore, a limiting structure is provided on both sides of the connecting beam;

[0027] The width of the upper plate matches the distance between the limiting structures, so that further limiting can be performed between the upper plate and the connecting beam.

[0028] Furthermore, a sixth connecting hole is provided on the bottom plate;

[0029] A seventh connection hole is provided on the connection wall of the existing building;

[0030] The connection plate can be connected to the connection wall of the existing building by connecting the sixth connection hole and the seventh connection hole with bolts and injecting grout.

[0031] Furthermore, after the bolt is installed in the connecting wall and before grouting of the connecting wall is performed, short steel bars are welded to the bolt by spot welding.

[0032] Furthermore, a grouting channel and a grouting channel are provided on the connecting wall;

[0033] The grouting channel is arranged below the grouting channel.

[0034] In a second aspect, the present application also discloses a building including a sliding energy dissipation node.

[0035] By adopting the above technical solution, the present invention has the following beneficial effects:

[0036] (1) The sliding energy dissipation node does not slip when subjected to wind loads and small earthquake loads, and the installed elevator structure can work together with the original structure in the horizontal direction.

[0037] (2) Under the action of a large earthquake, the nodes can slide back and forth to dissipate seismic energy, while also playing a role in seismic isolation and shock absorption, limiting the maximum horizontal seismic effect added to the original structure by the installed elevator structure, thus acting as a fuse.

[0040] (5) The connecting plate is fixed to the original structure through a double-sided anchor node of a clamping plate type. Bolt holes are opened in the original structure. After the bolts are installed, the holes are grouted by grooving or drilling to ensure a reliable connection between the multifunctional sliding energy dissipation node and the original structure.

[0041] (6) The node can be produced and constructed in a standardized manner, and different sizes can be selected according to actual needs, making the design and construction more flexible, overcoming the difficulties in connection, and improving the degree of structural integration and on-site assembly efficiency.

DETAILED DESCRIPTION

[0055] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0056] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0057] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0058] The present invention is further explained below in conjunction with specific implementation modes.

[0059] Example 1

[0060] like Figure 1-4 As shown, the present embodiment provides a sliding energy dissipation node between an additional elevator module and an existing structure, comprising a connecting beam 1, a T-shaped plate 2 and a connecting plate 3; the connecting plate 3 comprises an integrally connected bottom plate 4 and a side plate 5; the bottom plate 4 and the side plate 5 are vertically arranged; the T-shaped plate 2 comprises an integrally connected upper plate 6 and a lower plate 7; the upper plate 6 and the lower plate 7 are vertically arranged; a first connecting hole 8 and a second connecting hole 9 are respectively arranged at the relative position of the lower plate 7 and the side plate 5; the connecting plate 3 is connected to the T-shaped plate 2 by passing a pin shaft 10 through the first connecting hole 8 and the second connecting hole 9.

[0061] In order to improve the connection strength between the connecting plate 3 and the T-shaped plate 2, the side plates 5 can be set to two or more; the lower plate 7 can be set to one or more; the spacing between the side plates 5 is greater than or equal to the thickness of the side plates 5; the lower plate 7 is inserted between the gaps of the side plates 5 and connected.

[0062] Since the T-shaped plate 2 and the connecting plate 3 are connected by the pin 10, the design leaves a small space between the connecting plate 3 and the T-shaped plate 2, so that the bending moment generated can be released when there is a settlement difference between the original structure and the additional elevator.

[0063] The upper plate 6 is provided with a third connection hole 11; the connecting beam 1 is provided with a fourth connection hole 12; the third connection hole 11 and the fourth connection hole 12 are long strips and perpendicular to each other; the upper plate 6 is connected to the connecting beam 1 by fasteners passing through the third connection hole 11 and the fourth connection hole 12. The number of the third connection holes 11 is multiple and arranged in parallel; the number of the fourth connection holes 12 is multiple and arranged in parallel to each other.

[0064] Since the third connection hole 11 and the fourth connection hole 12 are long strip holes perpendicular to each other, a small-scale reciprocating slip can occur between the upper plate 6 and the connecting beam 1 under strong external force vibration, thereby dissipating earthquake energy while ensuring the relative stability of the connection. In addition, due to the length limitation of the third connection hole 11 and the fourth connection hole 12, it can play a role in seismic isolation and shock absorption in large earthquakes, limiting the maximum horizontal seismic effect added to the original structure by the installation of the elevator structure, and playing a role of a fuse.

[0065] Since there is a large stress at the sliding energy dissipation node, in order to avoid damage caused by excessive stress concentration, a pad 13 is further provided between the connecting beam 1 and the T-shaped plate 2; a fifth connection hole 14 is provided on the pad 13, and its position corresponds to the positions of the third connection hole 11 and the fourth connection hole 12. Different from the third connection hole 11 and the fourth connection hole 12, the fifth connection hole 14 is a circular bolt 17 hole.

[0066] In order to further limit the position between the upper plate 6 and the connecting beam 1, limiting structures 15 are provided on both sides of the connecting beam 1, and the width of the upper plate 6 matches the distance between the limiting structures 15. The limiting structures 15 on the connecting beam 1 can be provided by welding, or can be directly implemented by the structure of an I-beam or a C-beam.

[0067] The sliding energy dissipation node is connected to the connection wall 18 of the existing building through the connection plate 3. A sixth connection hole 16 is provided on the bottom plate 4, and a seventh connection hole 22 is provided on the connection wall 18 at a position corresponding to the sixth connection hole 16 of the bottom plate 4. The diameter of the seventh connection hole 22 is slightly larger than the diameter of the bolt 17. After the bolt 17 is set in the grouting connection hole, a short steel bar 19 is welded to the bolt 17 by spot welding, which can improve the firmness of the connection plate 3 installed on the connection wall 18 after the grouting operation.

[0068] The connection wall 18 is provided with a grouting channel 20 and a grouting channel 21; the grouting channel 20 is arranged below the grouting channel 21. The grouting channel 20 and the grouting channel 21 can be arranged on the same side or on different sides of the connection wall 18. There are two ways to arrange the grouting channel 20 and the grouting channel 21.

[0069] Mode 1: The grouting channel 20 includes a grouting slot and a grouting hose, and the grouting outlet channel 21 includes a grouting slot and a grouting outlet hose. The grouting slot and the grouting outlet slot are respectively trough bodies arranged on the connecting wall 18, and are connected to the seventh connecting hole 22. The grouting hose is arranged in the grouting slot, and the grouting material is injected into the seventh connecting hole 22 through the grouting hose. When the seventh connecting hole 22 is filled with grouting material, the excess grouting material will flow out from the grouting outlet hose.

[0070] Mode 2: The grouting channel 20 and the grouting channel 21 are grouting holes and grouting holes. The grouting holes and the grouting holes extend from the surface of the connecting wall 18 to the seventh connecting hole 22, and grouting material is injected into the seventh connecting hole 22 through the grouting holes. When the seventh connecting hole 22 is filled with grouting material, the excess grouting material will flow out from the grouting hole.

[0071] The grouting material is a room temperature grouting material, and the use environment is above 5°C. It must comply with the technical standards of JG / T 408-2013 "Sleeve Grouting Material for Steel Bar Connection" and JGJ 355-2015 "Technical Specification for Application of Steel Bar Sleeve Grouting Connection". The mixing water should comply with the provisions of JGJ 63-2006 "Concrete Water Standard". The following table shows the performance requirements of the grouting material:

[0072]

[0073] Note: The temperature of the test room during specimen molding should be 20±1℃, and the relative humidity should be greater than 50%; the temperature of the curing room should be 20±1℃, and the relative humidity should be greater than 90%; the temperature of the curing water should be 20±1℃. The temperature of the grouting material and mixing water should be consistent with the ambient temperature of the test room.

[0074] The whole process of bolt installation and grouting is divided into: pre-construction preparation, drilling, hole cleaning, bolt positioning and installation, grouting pipe soft installation, hole grouting, and final cleaning. Among them, the pre-construction preparation mainly includes: removing the decorative surface of the beam body at the bolt installation location, checking the materials and other materials and construction tools used for grouting, and grouting test operation; the drilling work mainly includes the drilling of the sixth connection hole and the seventh connection hole.

[0075] Specific installation steps: remove the decorative surface of the installation location, use a water drill to drill 2 bolt holes, then use a punch drill to drill 2 grouting holes and 2 slurry outlet holes, use auxiliary tools to clean the holes, install the bolt pair, then install the grouting pipe, and connect the grouting machine for grouting. After the grouting is completed, use rubber plugs to seal the grouting port and slurry outlet, and finally clean up.

[0076] The construction requirements during the grouting process are as follows:

[0077] (1) During the construction preparation stage, the internal and external surfaces of the building need to be cleaned and leveled. After the bolt pair is installed, epoxy mortar or type I rapid hardening cement is used to fill the gaps at the edges of the pad and concrete interface and the gaps at the ends of the bolts, leaving only the grouting ports and grout outlets.

[0078] (2) When installing the grouting nozzle, the gap between the grouting nozzle and the hole wall needs to be sealed with epoxy mortar or Type I quick-hardening cement to ensure that there is no leakage during grouting.

[0079] (3) When drilling bolt holes, the holes need to be kept horizontal. The inlet of the grouting hole should be set lower than the lowest position of the bolt hole, and the outlet should be connected to the bolt hole. The outlet position of the grouting hole should be higher than the highest position of the bolt hole, and the other end should also be connected to the bolt hole. When drilling the grouting hole, the hole should be drilled at an angle inclined to the building installation surface.

[0080] (4) When installing bolts, the screw should be kept in the center of the hole. Short steel bars can be spot welded on the screw or other measures can be taken.

[0081] (5) At the beginning of grouting, trial grouting is required to determine the appropriate grouting pressure and flow rate. At the same time, the bolt holes and grouting holes should be observed. When slurry continues to flow out of the grouting holes, grouting should be stopped and the grouting ports and grouting outlets should be sealed in time.

[0082] (6) Grouting operations should be carried out by injecting grouting materials from the grouting holes using the grouting method. Grouting should be stopped when the grouting material mixture at the joint of the grouting hole is higher than the highest point of the bolt hole. After the grouting is completed and inspected to be qualified, the grouting holes should be sealed. The sealing should be level with the original wall surface, and the remaining grout on the wall and ground should be cleaned up in time.

[0083] (7) The properties of cement slurry must meet the following requirements: the fluidity of the slurry should be controlled at 14-22s; the expansion rate of the slurry should be <3%; the initial setting time should be ≥4h, and the final setting time should be ≤24h; the slurry temperature should be controlled at 5-30℃ during grouting. When the ambient temperature is higher than 35℃, grouting should be carried out at a lower temperature.

[0084] The grouting material is timed from the time water is added, and the stirring time is 8-10 minutes; the slurry must be left to stand and defoam before use, and the standing time is 2 minutes. The slurry is stirred as it is used, and the stirred slurry must be used up within 30 minutes.

[0085] The grouting method can be one of the following three:

[0086] (1) Pressure grouting: low-pressure grouting technology is used to control the grouting pressure to control the slurry flow rate during the grouting process.

[0087] (2) Treatment of grout leakage: If grout leakage occurs, stop grouting and treat the leaking part. Continue grouting after the treatment is qualified.

[0088] (3) Sealing of grouting holes: After grouting is completed, the grouting tube can be removed. Sealing must be done in time to prevent the grouting cavity from overflowing from the hole cavity after being pressurized, resulting in incomplete grouting. The time interval between removing the grouting tube and sealing the rubber plug shall not exceed 1 second.

[0089] By adopting the above technical solution, the present invention has the following beneficial effects:

[0090] (1) The sliding energy dissipation node does not slip when subjected to wind loads and small earthquake loads, and the installed elevator structure can work together with the original structure in the horizontal direction.

[0091] (2) Under the action of a large earthquake, the nodes can slide back and forth to dissipate seismic energy, while also playing a role in seismic isolation and shock absorption, limiting the maximum horizontal seismic effect added to the original structure by the installed elevator structure, thus acting as a fuse.

[0092] (3) The slot node has a limiting function, which limits the maximum horizontal deformation value of the installed elevator structure and ensures the safety of the installed elevator structure.

[0093] (4) The sliding energy dissipation node is connected to the connecting plate through a T-shaped plate and a pin shaft. This design can release the bending moment generated when there is a settlement difference between the original structure and the added elevator.

[0094] (5) The connecting plate is fixed to the original structure through a double-sided anchor node of a clamping plate type. Bolt holes are opened in the original structure. After the bolts are installed, the holes are grouted by grooving or drilling to ensure a reliable connection between the multifunctional sliding energy dissipation node and the original structure.

[0095] (6) The node can be produced and constructed in a standardized manner, and different sizes can be selected according to actual needs, making the design and construction more flexible, overcoming the difficulties in connection, and improving the degree of structural integration and on-site assembly efficiency.

[0097] like Figure 5As shown, the present application includes a building including a sliding energy dissipation node having a building self-resetting beam-column and floor slab node structure. The sliding energy dissipation node in Example 1 and the building self-resetting beam-column and floor slab nodes in this embodiment all play an energy dissipation role, so that the building has better stability in natural disasters such as earthquakes. The sliding energy dissipation node in Example 1 is arranged on the floor slab body 811, beam body 818 or column body 819 in this embodiment and an elevator is installed.

[0098] The present embodiment provides a building self-resetting beam-column and floor node structure, including a floor body 811 and a beam-column support assembly 817 arranged at the bottom of the floor body 811, a node support assembly 812 is arranged between the beam-column support assembly 817 and the floor body 811, the beam-column support assembly 817 includes a node support frame group 813 and a reinforced main bracket 814 arranged on the side edge of the node support frame group 813, and a cross beam fixing bracket 815 and a column fixing bracket 816 are arranged on the reinforced main bracket 814.

The prestressed wing frame 822 includes a wing frame plate 844 disposed on the side edge of the main frame bracket 841 and a frame plate fixing frame 845 for connecting the wing frame plate 844. The main frame bracket 841 is located in the plate body spacing area of ​​the wing frame plate 844. The plate body of the wing frame plate 844 is provided with a swing installation groove 847, and the plate body of the main frame bracket 841 is provided with a steel strand connecting frame 846 connected to the swing installation groove 847.

[0104] In this embodiment, a surface frame type steel truss structure is composed of a main frame support 841, an end support rod 842 and an inner frame support rod 843, and the supporting effect on the floor main body 811 is maintained with the assistance of relevant fixing tools. The prestressed auxiliary wing frame 822 is composed of an auxiliary wing frame plate 844 and an inner frame support rod 843 to form a card frame structure, which is arranged on the periphery of the main frame support 841. Under normal conditions, it can help to increase the supporting range of the main frame support 841; at the same time, the auxiliary wing frame plate 844 has a certain range of motion relative to the main frame support 841, and can be folded a certain distance with the swing installation groove 847 as the folding point. The steel strand connecting frame 846 has steel strands for prestressed support built in, which are always in an elastic state, providing the necessary restoring force for the overall auxiliary wing frame plate 844 structure, which is used to dissipate seismic energy during vibration, reduce structural damage, and further reduce the impact of vibration force on the main frame support 841, so that the vibration force is consumed in the process of changing direction and flipping of the auxiliary wing frame plate 844, thereby further ensuring the stability of the main support frame 821 and the node support frame group 813 used to support the main support frame 821, that is, ensuring the stability of the overall beam-column support end.

[0105] In one case of this embodiment, see Figure 5 , Figure 6 and Figure 7 For the installation implementation structure of the lower support frame 823, the supporting substrate 824 and the bottom support frame 825, the present embodiment is designed as follows:

[0106] The main frame bracket 841 plate body extends downward and is provided with a bottom support frame 825. The bottom support frame 825 and the main frame bracket 841 are an integrated structure. A front support beam 851 is provided on the front side of the lower edge of the plate body of the main frame bracket 841, and a rear support beam 853 is provided on the rear side of the lower edge of the main frame bracket 841. The bottom ends of the front support beam 851 and the rear support beam 853 are respectively provided with a front beam bottom frame 852 and a rear beam bottom frame 854. The lower support frame 823 is fixedly installed on the front beam bottom frame 852 and the rear beam bottom frame 854.

[0107] The lower support frame 823 includes a bottom frame substrate 872 and a mounting rail frame 873 arranged on the bottom plane of the bottom frame substrate 872, the supporting substrate 824 includes a reset member support substrate 871 and an embedded mounting block 874 installed on the top of the reset member support substrate 871, the mounting rail frame 873 is provided with an inner rail mounting groove 875, the embedded mounting block 874 is embedded in the mounting rail frame 873 and fixed to the inner rail mounting groove 875 by a plurality of fixing bolts 876, and the reset member support substrate 871 is docked and installed with the prestressed reset support 836.

[0108] The bottom frame substrate 872 and the mounting track frame 873 are fixedly installed on the bottom of the main support frame 821, thereby forming a crossbeam structure at the bottom of the main support frame 821 to form a fixed support for the supporting substrate 824. The main body of the supporting substrate 824 is a reset member supporting substrate 871, which is arranged and installed along the track of the mounting track frame 873 through an embedded mounting block 874. As an example, two groups of supporting substrates 824 are installed on the mounting track frame 873 in the figure. The specific number and installation spacing of the supporting substrates 824 on the mounting track frame 873 can be determined according to the specific building structure.

[0109] In one embodiment, see Figure 5 and Figure 8 This embodiment is a further design of the above embodiment. On this basis, for the specific support implementation structure of the node support frame group 813, this embodiment is designed as follows:

[0110] A plurality of end rod mounting heads 862 are installed at the outer rod ends of the end support rods 842, a plurality of end rod positioning sleeves 863 fixed to the end rod mounting heads 862 are arranged on the plate body of the outer wing fixing frame 833, a plurality of frame supporting beams 865 are arranged on the frame supporting beam 865, the prestressed reset support 836 is matched one-to-one with the supporting base plate 824, a reset member frame 864 is arranged on the outer frame of the prestressed reset support 836, the reset member frame 864 is fixedly mounted on the corresponding frame supporting beam 865, a frame beam mounting head 866 is installed at the rod end of the frame supporting beam 865, and a frame beam positioning sleeve 867 for fixing the frame beam mounting head 866 is installed on the outer wing fixing frame 833.

[0111] The node support frame group 813 uses the outer wing fixed frame 833 as a supporting structure for the node support assembly 812. The outer wing fixed frame 833 is supported on the periphery of the frame structure composed of the main frame bracket 841, the end support rod 842 and the inner frame support rod 843. The outer rod end of the end support rod 842 is supported and fixed by the end rod mounting head 862, thereby supporting the four corners of the main support frame 821 to further improve the stability coefficient. In this embodiment, prestressed reset supports 836 are used to provide a bottom-up building self-reset force, and each prestressed reset support 836 is a self-reset support point. The number of supporting substrates 824 is determined according to the design number of prestressed reset supports 836.

[0112] For the specific implementation structure of the prestressed reset support 836, please refer to Figure 7 to Figure 10 , this embodiment is designed as follows:

[0113] The prestressed reset support 836 includes a reset member inner base 881 installed on the inner support fixing member 835, a middle support positioning frame 882 arranged at the midline position of the reset member inner base 881, and a middle support 883 installed on the middle support positioning frame 882. A middle telescopic bracket 885 is installed on the top of the middle support 883. A prestressed steel bar 886 is supported and installed on the middle telescopic bracket 885 through an elastic support head 884. An inserted support block 887 and an assembly plug plate 888 located on the side edge of the inserted support block 887 are arranged on the prestressed steel bar 886. An I-shaped slot 889 and a side wing slot 880 opened on the side edge of the I-shaped slot 889 are arranged at the midline position of the plate body of the reset member support base plate 871. The inserted support block 887 is connected to the I-shaped slot 889, and the side wing slot 880 is inserted into the slot installed in the side wing slot 880.

[0114] The inner base 881 of the reset member is the bottom support structure of the prestressed reset support 836. The middle support positioning frame 882 is the support structure at the midline position of the inner base 881 of the reset member, forming an upward positioning support for fixing and supporting the middle support 883. The middle telescopic bracket 885 is a vertical support structure erected on the middle support 883. The prestressed steel bar 886 is installed on the top of the middle telescopic bracket 885, and two elastic support base points are formed with the elastic support head 884 to connect and support the prestressed steel bar 886. The top of the stress steel bar 886 is assembled in a chimeric manner with the plate body of the reset member support base plate 871 through the two installation components, the internal support block 887 and the assembly plug plate 888. The overall structure allows the centerline support structure composed of the elastic support head 884 and the prestressed steel bar 886 to undergo a certain deformation during the vibration process. Therefore, as a prestressed element during the vibration process, it can resist the deformation of the structure. At the same time, it has a certain range of activity and deformation, and can absorb earthquake energy as an energy-absorbing component to reduce the vibration and damage of the structure. After the vibration ends, the restoring force provided by the elastic support head 884 will automatically reset the structure to its initial state, thereby achieving the recoverability of the structure.

[0115] The support stability of the above-mentioned prestressed element alone is still insufficient, so the present embodiment further provides the following structure:

[0116] The prestressed reset support 836 includes a median cross bracket 891, two of which are respectively installed on the median support positioning frame 882 and the median telescopic bracket 885. The prestressed reset support 836 also includes a plurality of prestressed support rods 892, which are arranged on both sides of the median support positioning frame 882.

[0117] The prestressed support rod 892 includes a support rod body 8101 and a threaded section 8102 arranged on the support rod body 8101, a top support plate 8103 is installed on the top of the support rod body 8101, and a bottom support plate 8104 is installed on the threaded section 8102, the top support plate 8103 and the bottom support plate 8104 are respectively rotatably installed on the middle cross bracket 891 through a top plate mounting sleeve 8105 and a bottom plate mounting sleeve 8106, and a torsion spring 8100 is wound around the periphery of the support rod body 8101, and the torsion spring 8100 is supported between the top support plate 8103 and the bottom support plate 8104, and the two ends of the torsion spring 8100 are fixed on the plate body of the top support plate 8103 and the bottom support plate 8104.

[0118] A plurality of top locking grooves 893 are provided on the plate body of the reset member support base plate 871, and a plurality of bottom locking grooves 894 are correspondingly provided on the plate body of the reset member inner base 881. Locking bolts 895 are installed on both the top locking grooves 893 and the bottom locking grooves 894. Rod end fixing blocks 8107 are installed on the top and bottom ends of the support rod body 8101, and rod end fixing heads 8108 are provided on the rod end fixing blocks 8107. The rod end fixing heads 8108 are fixedly locked to the corresponding locking bolts 895.

[0119] In this embodiment, the support structure in the frame of the prestressed reset support 836 includes an inner base 881 of the reset member located at the bottom and two middle cross supports 891 arranged in the middle position. This embodiment is also provided with a plurality of prestressed support rods 892. The prestressed support rods 892 are supported on the periphery of the prestressed element composed of the middle telescopic support 885, the elastic support head 884 and the prestressed steel bar 886 to form a peripheral prestressed reinforcement. The main body of the prestressed support rod 892 is the support rod body 8101. The column structure of the support rod body 8101 is fixedly supported between the inner base 881 of the reset member and the reset member support base plate 871. The top and bottom ends of the support rod body 8101 are fixedly locked to the corresponding locking bolts 895 through the rod end fixing head 8108 to form vertical support points in the upper and lower directions. These vertical support points are distributed on the periphery of the above-mentioned prestressed element to form a support structure for the outer ring of the prestressed element to maintain stability.

[0120] At the same time, the support rod body 8101 is also provided with a top support plate 8103 and a bottom support plate 8104, which are respectively positioned on the corresponding reset member support base plate 871; on the one hand, the top support plate 8103 and the bottom support plate 8104 are both rotatably installed, so that when the beams and the floor slabs are subjected to vibration, the two will rotate to a certain extent due to the vibration, and the rotational offset of the two will drive the two ends of the torsion spring 8100 to move, and then drive the torsion of the torsion spring 8100 to change. During the vibration process, it is necessary to overcome the elastic torsion, and then achieve the effect of elastic damping, so as to consume energy through the elastic force of the arc torque under the action of vibration, while maintaining the stability of the structure; after the vibration disappears, the reset trend of the torque is also conducive to generating a restoring force, which helps to reset the structure.

[0121] On the other hand, the bottom support plate 8104 is installed by means of a threaded connection, and there will be an upward and downward movement tendency during the rotation process. In this case, the distance between the top support plate 8103 and the bottom support plate 8104 will be reduced, thereby compressing the torsion spring 8100. As a result, the vibration force needs to overcome the elastic force formed by the compression of the torsion spring 8100, thereby further consuming the vibration force; and when the top support plate 8103 spirally moves up or down around the support rod body 8101, it will also form a friction damping effect, thereby further consuming the energy of the external vibration source.

[0122] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
