Description

Technical Field

[0001] This invention relates to the field of building seismic isolation technology, specifically to a mechanical seismic isolation bearing and method for prefabricated mobile houses. Background Technology

[0002] Prefabricated modular houses are commonly used in construction sites for buildings, bridges, water conservancy projects, or new energy projects. Often, due to cost considerations, construction companies do not implement seismic isolation measures for these modular houses. Instead, they simply install a concrete pad underneath and rigidly connect the square steel pipe beams at the bottom of the modular house to the concrete.

[0003] This type of connection will cause a large amount of construction vibrations on the construction site to be transmitted into the prefabricated temporary housing. This means that people can easily feel small amplitude but high frequency vibrations, which will significantly reduce the living or working experience of the prefabricated temporary housing. Summary of the Invention

[0004] To address the problems existing in the prior art, the present invention provides a mechanical seismic isolation bearing and method for prefabricated mobile houses, which can achieve mechanical seismic isolation without additional energy.

The columnar rotating component has a swing plate on one side inside the main support structure and a load-bearing plate encased in the building body on the other side. The end of the load-bearing plate is driven by a hinged linkage mechanism with a stop on the swing arm, and the hinged linkage mechanism with a stop on the swing arm is driven by an energy dissipation mechanism.

[0008] Furthermore, the main support structure includes two first steel rings spaced apart, and a second steel ring is respectively provided on the side away from the two first steel rings. The same vibration amplification mechanism is provided between the first steel rings, and the inner wall is respectively provided with a hinge linkage mechanism with a stop and a transmission connection to an energy dissipation mechanism. An energy dissipation mechanism is provided inside the second steel ring.

[0009] Furthermore, both ends of the gap between the two first steel rings are provided with sealing members. The sealing members include a third steel pad and an ear plate vertically arranged on the side close to the two third steel pads. A cylindrical rotating member is provided through the side wall of the third steel pad of the sealing member close to the force plate.

[0010] Furthermore, the fixed end and free end of the swing plate are located between the two sets of ear plates, respectively;

[0011] The free end of the swing plate is provided with a second long groove along its length. A drive shaft is slidably disposed in the second long groove. The two ends of the drive shaft pass through the sidewalls of two adjacent first steel rings respectively, and are respectively connected to the input end of the energy-consuming mechanism via a hinge linkage mechanism for the swing rod inside the first steel ring.

[0012] Furthermore, the pendulum has a hinged linkage mechanism for transmission and energy dissipation, including a third connecting plate horizontally disposed on the side wall of the main support structure and a first connecting plate vertically disposed on the bottom surface of the main support structure. The third connecting plate is vertically hinged to a first rotating plate, which has an arc-shaped groove. The output end of the vibration amplification mechanism is slidably disposed within the arc-shaped groove. The first rotating plate is also hinged to a first transmission rod, the other end of which is hinged to an L-shaped connector. The bent portion of the L-shaped connector is hinged to a second transmission rod, the other end of which is hinged to the first connecting plate. The other end of the L-shaped connector is hinged to a rotating component, which is rotatably disposed through the first connecting plate.

[0013] Furthermore, the output end of the rotating component passes through the first connecting plate; the first connecting plate is rotatably provided with a second transmission gear disk, the second transmission gear disk has a central gear disk on its shaft, and the central gear disk is fixedly connected to the output end of the rotating component; a gear rack is provided on the inner side of the edge of the second transmission gear disk; the central gear disk and the gear rack are meshed with the same first rotating gear; the central gear disk, the gear rack, and the first rotating gear constitute a gear forward and reverse rotation mechanism.

[0014] The first rotating gear is fixedly sleeved on the transmission shaft, and the transmission shaft is connected to the energy-consuming mechanism.

[0015] Furthermore, the energy-consuming mechanism includes a liner and a fine sand layer arranged sequentially from top to bottom within the main support structure, and the edge of the liner is rigidly suspended from the inner wall of the main support structure by multiple tension and compression energy-consuming components;

[0016] The drive shaft is spirally surrounded by a spiral metal sheet, which is disposed within a layer of fine sand. The spiral metal sheet has an elliptical structure, and the major radius of the spiral trajectory of the spiral metal sheet is greater than the distance from the center of the drive shaft to the liner, while the minor radius is less than the distance from the center of the drive shaft to the liner.

[0017] Furthermore, an energy-dissipating rubber pad is provided on the upper side of the liner, and the top of the energy-dissipating rubber pad is provided with multiple recesses, in which multiple elastic balls are placed, and the main support structure on the upper side of the elastic balls is provided with a cover plate, which abuts against the elastic balls.

[0018] Furthermore, the bottom of the liner is provided with multiple square platforms spaced apart, and the square platforms are arranged in a matrix.

[0019] A method for a mechanical seismic isolation bearing for prefabricated modular houses includes the following steps:

[0020] After the load-bearing plate is subjected to the vibration transmitted by the concrete pad layer under the prefabricated mobile house, it transmits the reverse vibration to the swing plate through the column rotating component. At this time, the swing plate produces a reverse and large swing.

[0021] The swing plate drives the swing rod through a hinged linkage mechanism that has pauses, outputting a circular motion trajectory and inputting it into an energy-consuming mechanism to complete mechanical vibration isolation.

[0022] Compared with the prior art, the present invention has the following beneficial technical effects:

[0023] This invention provides a mechanical seismic isolation bearing and method for prefabricated modular houses, including a main support structure, and a vibration conversion mechanism and an energy dissipation mechanism disposed within the main support structure. The main support structure is spaced within the building body.

A swing plate is disposed on one side of the columnar rotating member within the main support structure, and a load-bearing plate encased within the building body is disposed on the other side. The end of the load-bearing plate is driven by a hinged linkage mechanism with a paused swing arm, which is driven by the energy dissipation mechanism. In this invention, after the load-bearing plate receives vibration transmitted from the building body, the columnar rotating member transmits a reverse vibration to the swing plate, causing the swing plate to swing in the opposite direction with a large amplitude. The swing plate drives the hinged linkage mechanism with a paused swing arm to output a circular motion trajectory, which is then input into the energy dissipation mechanism, thus completing the mechanical seismic isolation.

[0038] The present invention will be further described in detail below with reference to specific embodiments. These descriptions are for explanation purposes only and are not intended to limit the scope of the invention.

[0039] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0040] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0041] The high-frequency vibrations described in this application are applicable to the following scenarios: construction, new energy, water conservancy, and municipal engineering projects where a large number of soil compaction machines are used for construction, and the vibrations of these machines are transmitted to the concrete foundation layer under the nearby prefabricated houses; another example is construction, water conservancy, municipal, and bridge engineering projects where drilling machines are used for construction, and when high-power drilling machines are used to work on hard rocks or buildings, the vibrations of the machines are also transmitted to the concrete foundation layer under the nearby prefabricated houses.

[0042] This invention provides a mechanical seismic isolation bearing for prefabricated modular houses, such as... Figure 1 and Figure 2 As shown, it includes a main support structure, as well as a vibration conversion mechanism and an energy dissipation mechanism installed within the main support structure; the gap of the main support structure is located within the concrete cushion layer on the underside of the prefabricated mobile house.

[0043] The vibration conversion mechanism includes a vibration amplification mechanism, which includes a cylindrical rotating member 807 rotatably mounted on the side wall of the main support structure. A swing plate 804 is provided on one side of the cylindrical rotating member 807 within the main support structure, and a load-bearing plate 5 is provided on the other side, encased in a concrete pad layer beneath the prefabricated mobile house. The end of the load-bearing plate 5 is connected to a hinged linkage mechanism with a paused swing arm, which is further connected to an energy-dissipating mechanism. It should be noted that, in this application, the hinged linkage mechanism with a paused swing arm is used to convert the up-and-down reciprocating motion of the swing plate 804 into circular motion.

[0044] Preferably, the main support structure includes two first steel rings 1 spaced apart, and second steel rings 2 are respectively arranged on the opposite side of the two first steel rings 1. The same vibration amplification mechanism is arranged between the first steel rings 1, and the inner wall of the first steel rings 1 is respectively provided with a hinge linkage mechanism with a pendulum that stops and starts, which is connected to the energy dissipation mechanism. The second steel rings 2 are provided with an energy dissipation mechanism inside. It should be noted that those skilled in the art can coat the outer wall of the main support structure with lubricating oil or other materials or use water to absorb the plastic wrap to reduce friction. At the same time, it can reduce the adhesion and slippage between the concrete and the main support structure, which is convenient for the later recycling of the device.

[0045] Furthermore, both ends of the gap between the two first steel rings 1 are provided with sealing members 4. The sealing member 4 includes a third steel pad 401 and an ear plate 402 vertically arranged near the two third steel pads 401. A cylindrical rotating member 807 is provided through the side wall of the third steel pad 401 near the force plate 5. It should be noted that, as Figure 12 and Figure 13 As shown, the first steel ring 1 has a second steel pad 888 at its top, and a second steel ring 777 at its edge. The second steel ring 777 fits into the top of the first steel ring 1 to prevent sand, dust, or concrete from entering. The second steel ring 2 has a first steel pad 201 at its bottom, and a first steel ring 202 at its edge. The first steel ring 202 fits into the bottom of the second steel ring 2. It should be noted that the gap between the second steel ring 2 and the first steel pad 201 is filled or bonded with waterproof tape. The waterproof tape is used to prevent water in the concrete from flowing into the fine sand layer 997.

[0046] Preferred, such as Figure 5 and Figure 6As shown, the fixed end and free end of the swing plate 804 are located between the two sets of ear plates 402, respectively. A second long groove 805 is provided along the length of the free end of the swing plate 804. A drive shaft 101 is slidably disposed within the second long groove 805, and both ends of the drive shaft 101 pass through the adjacent sidewalls of two adjacent first steel rings 1, respectively, and are respectively connected to the input end of the energy-consuming mechanism via a hinged linkage mechanism with a pause in the swing arm within the first steel ring 1. A first long groove 666 is provided on the sidewall of the first steel ring 1, and the free end of the drive shaft 101 passes through the first long groove 666. It should be noted that the hinged linkage mechanism with a pause in the swing arm also further amplifies the construction vibration, giving the force plate 5 a small amplitude vibration, thus causing the rotating component 14 to rotate. The speed is greater; it should be further explained that, in this embodiment, a transition plate 803 and a fourth connecting plate 806 are also sequentially arranged between the swing plate 804 and the cylindrical rotating member 807. One end of the fourth connecting plate 806 is fixed to the cylindrical rotating member 807 and is arranged between the ear plates 402 to improve the overall structural strength. The transition plate 803 is a plate-shaped structure and is spaced apart on the outside of the ear plates 402. The transition plate 803 and the swing plate 804 are an integral structure. The transition plate 803 can improve its connection strength with the cylindrical rotating member 807. At the same time, each set of ear plates 402 includes two spaced plate structures. The cylindrical rotating member 807 is horizontally arranged in the third steel pad 401 and can be rotatably arranged in the third steel pad 401 through a short shaft or bearing.

[0047] Preferred, such as Figure 3 As shown, the pendulum has a hinged linkage mechanism for transmission and energy dissipation, including a third connecting plate 17 vertically disposed on the side wall of the main support structure and a first connecting plate 13 vertically disposed on the bottom surface of the main support structure. The third connecting plate 17 is vertically hinged to a first rotating plate 18, which is provided with an arc-shaped slide groove 110. The output end of the vibration amplification mechanism is slidably disposed in the arc-shaped slide groove 110. The first rotating plate 18 is also hinged to a first transmission rod 12, the other end of which is hinged to an L-shaped connector 15. The bent part of the L-shaped connector 15 is hinged to a second transmission rod 16, the other end of which is hinged to the first connecting plate 13. The other end of the L-shaped connector 15 is hinged to a rotating member 14, which is rotatably disposed on the first connecting plate 13.

[0048] Preferred, such as Figure 4As shown, the output end of the rotating component 14 passes through the first connecting plate 13; a second transmission gear disk 104 is rotatably mounted on the first connecting plate 13, and a central gear disk 1041 is mounted on the axis of the second transmission gear disk 104, and the central gear disk 1041 is fixedly connected to the output end of the rotating component 14. A gear rack 1042 is provided on the inner side of the edge of the second transmission gear disk 104, and the central gear disk 1041 and the gear rack 1042 are meshed with the same first rotating gear 103. The central gear disk 1041, the gear rack 1042 and the first rotating gear 103 constitute a gear forward and reverse rotation mechanism; the first rotating gear 103 is fixedly sleeved on the transmission shaft 3, and the transmission shaft 3 is connected to the energy-consuming mechanism; it should be noted that the central gear disk 1041 and the gear rack 1042 are both incomplete gear structures, and the teeth are only continuously distributed in half of the area, while the first rotating gear 103 is a complete gear structure.

[0049] Preferred, such as Figure 7 As shown, the energy-consuming mechanism includes a liner 9 and a fine sand layer 997 arranged sequentially from top to bottom within the main support structure. The edge of the liner 9 is rigidly suspended from the inner wall of the main support structure by multiple tension and compression energy-consuming components 998. A spiral metal sheet 7 is spirally arranged around the shaft of the drive shaft 3. The spiral metal sheet 7 is disposed within the fine sand layer 997. The spiral metal sheet 7 has an elliptical structure, and the major radius of the spiral trajectory of the spiral metal sheet 7 is greater than the distance from the center of the drive shaft 3 to the liner 9, while the minor radius is less than the distance from the center of the drive shaft 3 to the liner 9. It should be noted that when setting the fine sand layer 997, it is necessary to... To ensure the dryness and waterproofness of the fine sand; it should be noted that, in this embodiment, a sliding layer is provided between the liner plate 9 and the second steel ring 2. The sliding layer is made of a multi-hole sliding material, and the sliding layer is made of rubber products, including one of polytetrafluoroethylene, modified polytetrafluoroethylene, ultra-high molecular weight polyethylene, and ultra-high performance polytetrafluoroethylene; the porous structure of the sliding layer is used for gas circulation in the upper and lower spaces of the liner plate 9, to avoid air pressure imbalance and facilitate the up and down movement of the liner plate 9; furthermore, the lower end face of the square steel tube beam 900 is provided with air holes, and the air holes are offset from the elastic sphere 999.

[0050] Preferred, such as Figure 8 , Figure 9 and Figure 10As shown, an energy-dissipating rubber pad 10 is also provided on the upper side of the liner 9, and a plurality of recesses 996 are provided on the top of the energy-dissipating rubber pad 10. A plurality of elastic balls 999 are placed in the recesses 996, and the elastic balls 999 abut against the building body. In this embodiment, the elastic balls 999 abut against the lower end face of the square steel pipe beam 900 at the bottom of the prefabricated mobile house. It should be noted that the recesses 996 are evenly distributed on the upper side of the energy-dissipating rubber pad 10, and the elastic balls 999 are also evenly distributed on the upper side of the energy-dissipating rubber pad 10, all of which are used to provide a relatively balanced abutment surface.

[0051] Preferred, such as Figure 11 As shown, the bottom of the liner 9 is provided with a plurality of square platforms 995 at intervals. The square platforms 995 are arranged in a matrix. It should be noted that there are grooves between the square platforms 995, and the grooves are all interconnected.

[0052] In another preferred embodiment of the present invention, when multiple mechanical seismic isolation bearings for prefabricated mobile houses as described in this application are sequentially connected in series, the first steel ring 1 is driven to both sides of the second steel ring 2. At the same time, the swing rods respectively set in the first steel ring 1 have a hinge linkage mechanism that stops and starts, which together transmits the energy dissipation mechanism acting on the second steel ring 2. It should be noted that the forward and reverse rotation outputs of the gear forward and reverse rotation mechanisms respectively set in the first steel ring 1 must be consistent at any time, so as to input mechanical energy to the energy dissipation mechanism for energy dissipation. Meanwhile, all the force plates 5 in this embodiment are sequentially fixed by the linkage steel bars 6, so that the frequency transmitted to the vibration amplification mechanism tends to be consistent, thereby ensuring the consistency of the transmission cycle of each component.

[0053] This invention provides a method for a mechanical seismic isolation bearing for prefabricated modular houses, comprising the following steps:

[0054] After the load-bearing plate 5 is subjected to the vibration transmitted by the concrete pad layer under the prefabricated mobile house, it transmits the reverse vibration to the swing plate 804 through the column rotating component 807. At this time, the swing plate 804 generates a reverse and large swinging tendency.

[0055] The swing plate 804 drives the swing rod to output a circular motion trajectory through a hinged linkage mechanism with pauses, and inputs it into the energy dissipation mechanism to complete mechanical vibration isolation and energy dissipation.

[0056] Specifically, after the force plate 5 is subjected to vibration, the force plate 5 drives the cylindrical rotating member 807 to reciprocate within the closed member 4. The cylindrical rotating member 807 drives the swing plate 804 to swing in the opposite direction. The swing plate 804 drives the drive shaft 101 in the second long groove 805 to swing up and down, and also swings along the axis of the swing plate 804. At the same time, the drive shaft 101 slides up and down within the arc-shaped sliding groove 110, driving the first transmission rod 12 to swing. During the swinging process, the first transmission rod 12 drives the L-shaped connecting member 15 and the second transmission rod 16 to swing, and at the same time generates The push force causes the first rotating plate 18 to swing slightly, the L-shaped connector 15 drives the rotating part 14 to make a circular motion, the output end of the rotating part 14 drives the shaft gear disk 1041 to rotate, the shaft gear disk 1041 drives the first rotating gear 103 meshing with it to rotate, the first rotating gear 103 drives the gear rack 1042 meshing with it to rotate, the rotation process of the first rotating gear 103 is a periodic equal angle bidirectional rotation, and the position of the first rotating gear 103 remains unchanged during the rotation on the second transmission gear disk 104;

[0057] The first rotating gear 103 drives the transmission shaft 3 to rotate periodically at equal angles in both directions. Since the spiral metal plate 7 on the transmission shaft 3 has an elliptical structure, it periodically lifts the liner 9. During this lifting process, the energy-dissipating component 998 is compressed and dissipates energy. The energy-dissipating rubber pad 10 and the elastic ball 999 on the liner 9 are also compressed from above, dissipating energy. During the periodic rotation of the spiral metal plate 7, a certain amount of space appears in the periodically lifted liner 9. At this time, the fine sand near the spiral metal plate 7 is driven and reciprocates along the axial direction of the transmission shaft 3 to the end of the second steel ring 2 near the first steel ring 1, dissipating energy in the process. The gaps between the square platforms 995 at the bottom of the liner 9 serve to guide the fine sand, helping to level the sand and preventing excessive accumulation of fine sand on one side, which could cause the lower end of the liner 9 to be unable to fall back down due to the second steel ring 2 being close to the first steel ring 1.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein; and these modifications or substitutions 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.
