Technical Field

[0001] The invention belongs to the technical field of building shock-absorbing equipment, and in particular relates to an assembled node connection device with a flexible shock-absorbing function, an assembly method and a shock-absorbing method. Background Art

[0002] Prefabricated building structures are a construction method in which some or all of the building components are prefabricated in the factory and then transported to the construction site for assembly and installation. Its main features include standardized design, industrialized production, prefabricated construction, and integrated decoration. This construction method can effectively improve the stability and consistency of project quality, shorten the construction period, and reduce on-site wet operations and construction waste.

[0003] The beam-column joint is a key part of the house frame structure. The stress condition in the core area of ​​the beam-column joint is relatively complex. When the earthquake load acts repeatedly, it often causes cross cracks in the core area and damage to the column ends. Therefore, it is very necessary to install a shock-absorbing device at the beam-column joint for the earthquake resistance of the house. The node energy-dissipating structure of the existing prefabricated building structure usually uses angle steel deformation and bolt friction to dissipate seismic energy, which is difficult to achieve the ideal shock-absorbing effect.

[0004] The node energy dissipation structures of existing prefabricated building structures mostly use angle steel deformation or bolt friction energy dissipation, which has the following defects: ⑴ The shock absorption effect is limited, and it is difficult to dissipate earthquake energy in multiple directions at the same time; ⑵ Relying on metal deformation or friction, prone to fatigue failure and short service life; ⑶The installation and disassembly process is complicated, making it difficult to adjust or maintain quickly. Summary of the invention

[0024] Compared with the prior art, the present invention has the following beneficial effects: ⑴ The first connection component and method of the present invention have significant shock absorption effect: using a hydraulic energy dissipation system (limiting ball + annular energy dissipation groove + hydraulic oil), the hydraulic oil circulates, compresses and expands during an earthquake, converting the seismic energy into internal energy, and the energy consumption efficiency in the X and Y directions is increased by more than 40%. Convenient and reversible installation: utilizing the thermal expansion and contraction characteristics of hydraulic oil, the limiting ball is automatically clamped at room temperature, the connection strength is enhanced at high temperature, and the volume is reduced at low temperature for easy disassembly, realizing tool-free rapid disassembly and assembly. The connecting sleeve supports multiple forms (├, ┼, ┴, ┬, ┤, etc.), adapts to complex node layouts, and improves assembly flexibility.

[0025] (2) The secondary energy dissipation of the second connection assembly and method of the present invention enhances redundancy: through the extrusion friction between the columnar elastic block and the second spring, combined with elastic deformation and dynamic damping adjustment, the seismic energy is further dissipated to form a multiple shock-absorbing mechanism. Dynamic adaptive adjustment: During an earthquake, the limit block and the columnar elastic block are in reciprocating contact, and the spring compression and rebound form dynamic damping to adapt to seismic forces in different directions and avoid structural displacement. Modular design: The multi-form design of the connection sleeve supports rapid assembly, and the limit holes and elastic blocks are standardized to reduce construction complexity.

[0026] ⑶ Rapid disassembly, assembly and resetting of the third connection assembly and method of the present invention: The crossbeam and the connection sleeve are connected by a limit column and an elastic ball, and the third spring provides a preload. It can be inserted with one click during installation and separated by reverse operation during disassembly. Annular damping energy dissipation: During an earthquake, the elastic ball moves along the annular mounting hole, dissipating energy through friction and the damping effect of the annular limit plate, adapting to multi-directional vibrations with high shock absorption efficiency. Anti-fall-off design: The diameter of the annular limit plate is smaller than that of the elastic ball, ensuring that the elastic ball does not fall off during movement, while allowing free circumferential movement to enhance reliability.

[0027] ⑷ The fourth connection assembly and method of the present invention can balance the bidirectional seismic force: the elastic damping unit (rubber gasket + conical spring) is symmetrically arranged along the X / Y direction, the rubber gasket provides initial shock absorption, and the conical spring consumes energy through friction and elastic deformation when compressed, so as to balance the bidirectional vibration. Anti-residual deformation: the shape memory alloy ring (SMA) undergoes phase deformation and absorbs energy during an earthquake, and is reset by heating after the earthquake, thereby reducing the accumulation of plastic deformation and extending the service life. Pre-installed limit grooves simplify construction: the pre-installed limit grooves at the ends of the beams are directly engaged with the rubber gaskets of the connecting sleeves, reducing the number of on-site adjustment steps and improving assembly efficiency by 60%.

[0028] ⑸ The core advantages of each assembly method of the present invention: Hydraulic system pre-tightening: The initial tightening force is ensured by the compressed state of the hydraulic oil, combined with the precise alignment of the limit ball to avoid installation deviation. Modular component alignment: The standardized design of the limit hole and the elastic block simplifies the assembly process and supports the rapid adaptation of multi-form connecting sleeves. Temperature adjustment without tools: The thermal expansion and contraction characteristics of hydraulic oil are used to achieve normal temperature installation and low temperature disassembly, reducing maintenance costs.

[0029] ⑹ The core advantages of each shock absorption method of the present invention: Energy conversion mechanism: hydraulic oil circulation compression and expansion, elastic component friction deformation, converting earthquake energy into heat energy and internal energy to avoid metal fatigue failure. Dynamic damping adjustment: bidirectional sliding piston, elastic ball annular movement and other designs, adaptive to different earthquake directions, continuous energy absorption. Self-reset capability: hydraulic oil volume recovery after earthquake, spring elastic reset, SMA shape memory effect, ensure that the structure returns to its original position and can be reused.

[0031] Main component symbols: DETAILED DESCRIPTION

[0032] The present invention will be further described below in conjunction with the accompanying drawings: Figures 1 to 5 A first embodiment of the present invention is shown.

[0033] See also Figures 1 to 5 As shown, the first connection assembly 5 of the assembled node connection device with flexible shock-absorbing function includes a first column 1 and a second column 2 axially connected by a connecting sleeve 3, and a crossbeam 4 radially connected by the connecting sleeve 3; The first column 1 and the second column 2 are connected via a first connecting component 5 of a linkage damping mechanism of a limiting ball 51 and an annular energy dissipation groove 52 .

[0034] See also Figure 5 As shown, the first connection assembly 5 is composed of a hydraulic energy dissipation system; the hydraulic energy dissipation system includes a plurality of limiting balls 51 arranged on the lower surface of the first column 1, an annular energy dissipation groove 52 correspondingly arranged on the upper surface of the second column 2, and the limiting balls 51 are embedded in the annular energy dissipation groove 52; arc plates 53 are arranged on both sides of the limiting balls 51, the arc plates 53 are connected to the piston 55 through the arc rod 54, the piston 55 is connected to the arc plug cylinder 56, and the arc plug cylinder 56 is filled with hydraulic oil 57; The hydraulic oil 57 in the arc plug barrel 56 of the hydraulic energy dissipation system is always in a compressed state, and the limit ball 51 is clamped between the two arc plates 53 by utilizing the tendency of the hydraulic oil 57 to expand outward. Limiting rings 551 are provided at both ends of the arc plug barrel 56, and the position of the piston 55 is limited by the limiting rings 551. During installation, the limit ball 51 is squeezed between the two arc plates 53, and the hydraulic oil 57 in the arc plug barrel 56 is compressed to generate expansion force, clamping the limit ball 51; the two arc plates 53 slide in the annular energy dissipation groove 52, compressing the hydraulic oil 57, that is, the hydraulic oil 57 has a tendency to increase in volume, and the two arc plates 53 have an extrusion force on the limit ball 51, especially the higher the ambient temperature, the greater the extrusion force of the two arc plates 53 on the limit ball 51, thereby locking the limit ball 51 in the annular energy dissipation groove 52, and realizing the quick connection between the first column 1 and the second column 2. When disassembling the first column 1 and the second column 2, lower the ambient temperature of the first column 1 and the second column 2, reduce the volume of the hydraulic oil 57, reduce the squeezing force of the two arc plates 53 on the limiting ball 51, and then forcefully separate the first column 1 and the second column 2. By utilizing the characteristic that the volume of the hydraulic oil 57 changes with temperature, the first column 1 and the second column 2 can be quickly installed and disassembled. The volume of the hydraulic oil 57 in the arc plug cylinder 56 shrinks by cooling, and the connection components are separated after the clamping force is reduced; it should be noted that the arc surface of the arc plate 53 in contact with the limiting ball 51 is adapted to the arc surface of the limiting ball 51, and when the two arc plates 53 squeeze against the limiting ball 51, the arc surfaces of the two arc plates 53 just fit with the limiting ball 51, further locking the limiting ball 51; During an earthquake, a relative horizontal displacement will occur between the first column 1 and the second column 2, and the limiting ball 51 will slide back and forth in the annular energy dissipation groove 52 and squeeze the arc plate 53, and the arc plate 53 will drive the piston 55 to slide in the arc plug cylinder 56, thereby compressing and expanding the hydraulic oil 57, and continuously converting the earthquake energy into the internal energy of the hydraulic oil 57 for consumption. Compared with ordinary spring shock absorption, the service life is longer. By setting the annular energy dissipation groove 52 and the limiting ball 51, flexible shock absorption in the x direction and the y direction is achieved, and the energy consumption effect is better.

[0035] In this embodiment, when the first column 1 and the second column 2 are not connected, the distance between the arc plates 53 on both sides of the limiting ball 51 is smaller than the diameter of the limiting ball 51; in a preferred embodiment, when the first column 1 and the second column 2 are not connected, the smaller the distance between the two arc plates 53, the greater the pressing force of the hydraulic oil 57 on the limiting ball 51, and the stronger the connection between the first column 1 and the second column 2. It should be noted that when the first column 1 and the second column 2 are not connected, a certain gap should be left between the two arc plates 53 to facilitate the limiting ball 51 to be squeezed between the two arc plates 53. An arc groove 59 adapted to the fixed rod 58 is arranged in the annular energy dissipation groove 52; a plurality of limiting balls 51 are distributed in a circular array, and during an earthquake, the arc plate 53 drives the piston 55 to slide in both directions, and the hydraulic oil 57 in the arc plug cylinder 56 is cyclically compressed and expanded, and its reaction force forms dynamic clamping, and the hydraulic oil 57 flows to dissipate energy during an earthquake; an arc limiting groove is arranged between the arc rods 54 to ensure the stability of the limiting ball 51 when sliding and avoid structural displacement; the hydraulic oil 57 in the hydraulic energy dissipation system changes with temperature, and the expansion of the hydraulic oil 57 at room temperature forms a stable clamping force on the limiting ball 51, and the high temperature enhances the connection strength, and the low temperature facilitates disassembly; the connecting sleeve 3 supports a variety of forms, including ├ shape, ┼ shape, ┴ shape, ┬ shape, and ┤ shape; to meet the layout requirements of different nodes and improve assembly flexibility.

The hydraulic oil 57 forms a dynamic clamping force in the compression and expansion cycle, thereby enhancing the structural stability. (4) Energy dissipation and reset: After the earthquake, the hydraulic oil 57 gradually recovers its initial volume due to temperature change, and the limiting ball 51 is reset in the annular energy dissipation groove 52; the elastic deformation auxiliary structure of the arc plate 53 returns to its original position to ensure that the device can be reused.
