Description

Technical Field

[0001] The invention belongs to the technical field of assembled buildings and relates to an assembled beam-column node. Background Art

[0002] Prefabricated buildings are a type of building structure that is being vigorously promoted at this stage. They transfer a large number of on-site work processes in traditional construction methods to the factory for advance operation, and then package the building components and accessories processed and manufactured in the factory. After transporting them to the construction site, they are installed and adjusted on site through reliable connection methods and then assembled and installed.

[0003] At present, prefabricated buildings are divided into five types according to the form of prefabricated components and construction methods: block buildings, plate buildings, box-type buildings, frame plate buildings and lifting plate and layer buildings. Frame plate buildings are quite popular in the market because of their reasonable structure, which can reduce the weight of the building and have flexible internal divisions. Frame plate buildings are composed of prefabricated frames and plates. Their load-bearing structures generally have two forms: one is a frame structure system in which columns and beams form a load-bearing frame, and then the floor slabs and non-load-bearing internal and external wall panels are placed; the other is a load-bearing plate-column structure system composed of columns and floor slabs, and the internal and external wall panels are non-load-bearing. The load-bearing frame is generally a heavy reinforced concrete structure, and there are also steel and wood frames and plate combinations, which are mostly used in light prefabricated buildings.

[0029] The current prefabricated beam-column nodes, in the conventional sense, refer to the intermediate connection structure formed by the column and multiple beams. The intermediate connection structure is usually formed by rigidly connecting the column and multiple beams with bolts. The prefabricated beam-column nodes formed under such a connection method have high rigidity. Under sudden multi-directional composite seismic loads, the prefabricated beam-column nodes will make the structure vulnerable to damage, resulting in poor reliability of the overall building.

[0030] In view of the technical problem that the existing assembled beam-column joints have high rigidity and poor seismic resistance due to the inability to absorb and consume earthquake energy through energy consumption, resulting in poor reliability of the entire building, the present invention provides a new assembled beam-column joint. Figure 1 To the attached Figure 7 , the technical solution in the present invention is described clearly and in detail.

[0031] It should be further explained that, in the description of the embodiments of the present invention, unless otherwise specified, “ / ” means or. For example, A / B can mean A or B. The “and / or” in the text is merely a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present invention, “multiple” refers to two or more than two.

[0032] The following terms "first", "second", "third" and "fourth" are used for descriptive purposes only and should not be understood to suggest or imply relative importance or implicitly indicate the number of technical features indicated. Thus, a feature defined as "first", "second", "third" and "fourth" may explicitly or implicitly include one or more of the features.

[0033] Example 1

[0034] like Figures 1 to 4 As shown, the present invention provides an assembled beam-column node, which includes a connecting seat 1 and two composite damping structures 2 arranged on both sides of the connecting seat 1, with a difference of 180 degrees between the two composite damping structures 2, so as to realize the connection of the cross beam 3 and the column in a straight structure.

[0035] Specifically, the connecting seat 1 is arranged between the first column and the second column, the upper end surface of the connecting seat 1 is used to be fixedly connected to the lower end surface of the first column, and the lower end surface of the connecting seat 1 is used to be fixedly connected to the upper end surface of the second column. Two special-shaped slots are provided on the connecting seat 1, and the special-shaped slots are filled with damping grease for isolation and shock absorption. One end of the two composite damping structures 2 is respectively used to be connected to the two beams 3 one by one, and the other end is respectively connected to the connecting seat 1. The composite damping structure 2 constitutes a buffering energy dissipation structure while reliably connecting the column and the beam 3 structure, which can significantly reduce the seismic energy on the path of seismic energy transmission, so that the influence factor of the seismic action on the building is minimized, and its safe and stable reliability is ensured.

[0036] like Figure 2 As shown, the structure of the composite damping structure 2 includes a first connection plate 21, a second connection plate 22, a ball head column 23 and a plurality of dampers 24, wherein the first connection plate 21 and the second connection plate 22 are arranged in parallel and at intervals, and are used as transition structures for connecting with the connection seat 1 and the cross beam 3 respectively, and the role of this part is the same as that of the flange in the mechanical field, which is to play a connecting role. The ball head column 23 is arranged in the middle of the second connection plate 22, and one end of the ball head column 23 is fixedly connected to the first connection plate 21, and a plurality of dampers 24 are evenly arranged around the ball head column 23, and the two ends of the plurality of dampers 24 correspond to the first connection plate 21 and the second connection plate 22 one by one and are fixedly connected, and the evenly distributed structural arrangement of the plurality of dampers 24 ensures the balance of mass, and at the same time, the synergistic action of the plurality of dampers 24 can consume the vibration energy in multiple directions, especially the vibration energy along the length direction of the damper 24, and the level of the vibration energy can be reduced under the balanced action.

[0037] Specifically, as a further refinement of this embodiment, the damper 24 is preferably a viscous damper, which uses the viscosity of the liquid to provide damping to dissipate vibration energy, buffer the vibration energy, and achieve the purpose of shock absorption, thereby increasing the safety and stability of the building structure.

[0038] In this embodiment, the viscous damper not only supports and connects the structure, but also consumes the vibration energy along the transmission path of the vibration energy, thereby reducing the vibration energy.

[0039] Specifically, as a further refinement of this embodiment, the structure of the ball head cylinder 23 includes a cylinder and a ball head. The ball head is located at one end of the cylinder and is fixedly connected to the cylinder. The other end of the cylinder is fixedly connected to the first connecting disk 21. The cylinder is inserted into the second connecting disk 22. The structure formed by the cylinder and the ball head matches the special-shaped slot.

[0040] In actual use, the first connection plate 21 is fixed to the end face of the crossbeam 3, and the second connection plate 22 is fixed to the side of the connection seat 1. The ball head of the ball head column 23 is embedded in the special-shaped slot on the connection seat 1 to form a spherical connection pair. When the multi-directional vibration energy is transmitted, this structure can transmit the multi-directional vibration energy to the spherical surface of the special-shaped slot through the ball head column 23. There is surface contact between the spherical surface and the enveloping spherical surface, and the contact surface is relatively large, which avoids the problem of stress concentration. In addition, in order to achieve vibration isolation while achieving connection, damping grease is filled between the ball head of the ball head column 23 and the special-shaped slot. The damping grease can provide a good isolation effect on the one hand, and the high viscosity property can also play a damping role on the other hand, thereby reducing vibration noise and providing buffering protection.

[0041] Specifically, as a further refinement of this embodiment, the damping grease can be one of polybutene damping grease, polysiloxane damping grease, polybutene + polysiloxane damping grease, ethylene and olefin polymer damping grease. The addition of damping grease forms an oil film between the ball head and the special-shaped slot of the ball head column 23. The oil film can block the energy of vibration and also use its damping characteristics to reduce the transmitted vibration.

[0042] Specifically, as a further refinement of the present embodiment, a sealing structure 1 is provided on the cylinder of the ball head cylinder 23 for sealing the damping grease to prevent leakage of the damping grease and prevent entry of external impurities and dust.

[0043] Specifically, the sealing structure 1 is preferably an O-ring, which is embedded in an annular groove 1 opened in the circumferential direction of the cylinder, the width of the annular groove 1 matches the O-ring, and the depth of the annular groove 1 and the diameter of the O-ring meet the following relationship:

[0044] h=0.7d,

[0045] Where h is the depth of the annular groove and d is the diameter of the O-ring.

[0046] Specifically, as a further refinement of the present embodiment, a sealing structure three is provided between the joint surfaces of the second connection plate 22 and the connection seat 1 to prevent the entry of water and dust.

[0047] Specifically, as a further refinement of the present embodiment, the sealing structure three is preferably an O-ring, which is embedded in the annular groove two provided on the second connecting disk 22, and the shape of the annular groove two matches the O-ring.

[0048] As a further refinement of this embodiment, from the perspective of processing and ease of installation, specifically, Figure 1As shown, the structure of the connecting seat 1 includes a first connecting block 11 and a second connecting block 12. The first connecting block 11 and the second connecting block 12 are connected by bolts to form a detachable connecting structure, and a special-shaped groove hole for clamping the ball head and the cylinder of the ball head cylinder 23 is formed on the joint surface of the two.

[0049] Specifically, Figure 2 As shown, as a further refinement of this embodiment, the first connecting block 11 includes a first block body, and the cross section of the first block body is square, such as Figure 2 and Figure 3 As shown, a plurality of first connection holes are provided on the first block, and the first connection holes are used to pass through the first connection members, and the first connection members are used to fix the first connection block 11 and the second connection block 12. For the convenience, the first connection members are not exposed on the surface of the first block, as shown in FIG. Figure 3 As shown, the first connection hole is made into a countersunk hole structure. The first flange is fixedly mounted on the first end of the first block, and a plurality of second connection holes are provided on the first flange. The second connection holes are used to pass through the second connection members, and the second connection members are used to achieve the fixation of the connection seat 1 and the first column. Two special-shaped grooves 1 are also provided at the second end of the first block away from the first flange, and the two special-shaped grooves 1 are symmetrically arranged.

[0050] Specifically, as a further refinement of this embodiment, the second connecting block 12 includes a second block, the cross-section of the second block is square, and a plurality of third connecting holes are opened on the second block. The third connecting holes correspond to the first connecting holes one by one and are used to pass the first connecting member. In order to prevent the first connecting member from being exposed on the surface of the second block, the third connecting hole can be made into a blind hole structure, and the second flange is fixed on the first end of the second block. A plurality of fourth connecting holes are opened on the second flange, and the fourth connecting hole is used to pass the third connecting member. The third connecting member is used to fix the connecting seat 1 and the second column. Two special-shaped grooves 2 are also opened at the second end of the second block away from the second flange. The two special-shaped grooves 2 are symmetrically arranged, and the special-shaped grooves 2 and the special-shaped groove 1 are assembled to form a special-shaped slot hole, and the shape of the special-shaped slot hole matches the free end structure of the ball head column 23.

[0051] Specifically, as a further improvement plan of this embodiment, a sealing structure 2 is provided around the special-shaped groove 2 and the special-shaped groove 1 to seal the damping grease to prevent leakage of the damping grease and prevent entry of external impurities and dust.

[0052] Specifically, as a further improvement plan of this embodiment, the sealing structure 2 is preferably an O-ring, which is embedded in the annular groove opened around the special-shaped groove 1, the special-shaped groove 2 and the periphery to seal the damping grease.

[0053] Specifically, as a further improvement scheme of the present embodiment, in order to improve the multi-directional seismic performance of the composite damping structure 2, a plurality of evenly distributed deformation plates 25 are added between the first connecting plate 21 and the second connecting plate 22, one end of the plurality of deformation plates 25 is fixedly connected to the second connecting plate 22, and the other end is fixedly connected to a slider, the slider is clamped in a slide groove opened on the first connecting plate 21, and the slide groove is spiral, and the distance from the first end of the slide groove to the center of the first connecting plate 21 is larger than the distance from the second end of the slide groove to the center of the first connecting plate 21, forming an inclined slide groove, which structure can facilitate the deformation plate 25 to convert vibration into the internal energy of the deformation plate during the process of self-deformation, and at the same time, the structure with one end moving and the other end fixed can convert the vibration of the deformation plate 25 into the movement of the end of the deformation plate 25 to consume the energy of the vibration during the process of self-deformation.

[0054] Specifically, considering the reset ability and service life of the deformation piece 25, the material of the deformation piece 25 is beryllium bronze, which is bronze with beryllium as the main added element. The beryllium content of beryllium bronze is 0.2% to 2%, and a small amount of cobalt or nickel as the third component (0.2% to 2.0%) is added. The alloy can be heat-treated and strengthened, and is an ideal high-conductivity, high-strength elastic material. Beryllium bronze is non-magnetic, spark-resistant, wear-resistant, corrosion-resistant, fatigue-resistant and stress-relaxation-resistant, and is easy to cast and press-form. Its high-strength elastic characteristics can ensure that it can withstand multiple deformations while maintaining its structure unchanged, so as to achieve the purpose of converting kinetic energy into internal energy during the deformation process to consume vibration energy.

[0055] Specifically, the beryllium bronze used in the embodiment of the present invention is high-strength and wear-resistant cast beryllium copper C82800. High-strength and wear-resistant cast beryllium copper C82800 has high elasticity, and is wear-resistant and fatigue-resistant. It can greatly increase the service life of the deformation plate 25 and reduce the economic losses caused by replacing the deformation plate 25, thereby achieving the purpose of reducing economic costs.

[0056] In order to further dissipate energy, an energy dissipation block can be provided at both ends of the slide groove respectively. The energy dissipation block is used to collide with the slider to dissipate energy when the slider moves to the preset position of the slide groove. The energy dissipation block can be made of highly elastic material, and in specific implementation, rubber or highly elastic polyethylene carbon fiber composite resin can be preferably used.

[0057] Specifically, the cross-section of the energy dissipation block used in the embodiment of the present invention can be a cuboid or a cube, and the corners of the cuboid or the cube are rounded to reduce stress concentration, which is beneficial to increase the service life of the energy dissipation block.

[0058] In actual use, such as Figure 4In the connection state shown, when multi-directional vibration occurs, the ball head column 23 and the damping grease are used to provide good isolation, while reducing vibration noise and providing buffering protection. Multiple dampers 24 and a deformable plate 25 that can be displaced at one end and an energy dissipation block work together to buffer multi-directional vibrations, and together play a role in reducing the vibration energy level, protecting the safety of the building and improving its reliability.

[0059] Example 2

[0060] As a further improvement scheme based on the technical foundation of the above embodiment, Figure 5 As shown, in this embodiment, a prefabricated beam-column node is provided for realizing an L-shaped connection between the cross beam 3 and the column at the turning point of the building structure.

[0061] Specifically, as a further refinement of the technical foundation of this embodiment, the assembled beam-column node includes a connection seat 1 and two composite damping structures 2 arranged on both sides of the connection seat 1, the two composite damping structures 2 are 90 degrees apart, and the two composite damping structures 2 are respectively located on two adjacent sides of the connection seat 1, and are respectively used to be connected to the two beams 3 in a one-to-one correspondence. The assembled beam-column node constitutes a building buffer energy dissipation structure, which can significantly reduce the seismic energy on the path of seismic energy transmission, so that the influence factor of the seismic action on the building is minimized, and its safety and stability reliability are guaranteed.

[0062] Example 3

[0063] As a further improvement scheme based on the technical foundation of the above embodiment, Figure 6 As shown, in this embodiment, a prefabricated beam-column node is provided for realizing a T-shaped connection between the cross beam 3 and the column at the middle partition connection of the building structure.

[0064] Specifically, as a further refinement of the technical foundation of this embodiment, the assembled beam-column node includes a connection seat 1 and three composite damping structures 2 arranged on three adjacent sides of the connection seat 1, the three composite damping structures 2 are 90 degrees apart, and are respectively used to be connected to the three beams 3 in a one-to-one correspondence. The assembled beam-column node constitutes a building buffer energy dissipation structure, which can significantly reduce the seismic energy on the path of seismic energy transmission, so that the influence factor of the seismic action on the building is minimized, and its safety and stability reliability are ensured.

[0065] Example 4

[0066] As a further improvement scheme based on the technical foundation of the above embodiment, Figure 7 As shown, in this embodiment, a prefabricated beam-column node is provided for realizing the connection of the cross beam 3 and the column in a cross structure at the middle partition connection of the building structure.

[0067] Specifically, as a further refinement of the technical foundation of this embodiment, the assembled beam-column node includes a connection seat 1 and four composite damping structures 2 arranged on four adjacent sides of the connection seat 1, and the four composite damping structures 2 are 90 degrees apart and are respectively used to be connected to four beams 3 in a one-to-one correspondence. The assembled beam-column node constitutes a building buffer energy dissipation structure, which can significantly reduce the seismic energy on the path of seismic energy transmission, so that the influence factor of the seismic action on the building is minimized, and its safety and stability reliability are guaranteed.

[0068] It is worth noting that the assembled beam-column node provided by the present invention can also have other expansion forms depending on the use environment. For example, the cross-section of the middle connecting seat 1 can be expanded to a regular hexagon, a regular octagon and a regular hexadecagon, so as to achieve a connection between the main supporting columns and the circumferential supporting beams similar to those in a tent, so that the connecting node has a composite effect of shock absorption while achieving a supporting connection.

[0069] The assembled beam-column node provided by the present invention utilizes the snap-fit ​​connection between the ball head column and the special-shaped slot to realize a universal sliding connection, and transmits the multi-directional vibration energy through the ball head column to the special-shaped slot to realize the suppression and isolation of the vibration energy through the damping grease. At the same time, the damping grease can also consume the dynamic vibration energy to avoid the further transmission of large-level vibration energy. At the same time, multiple dampers are evenly arranged, and the lateral vibration energy can be dissipated while realizing reliable support and connection. One end of the deformation sheet is fixed, and the other end is movably arranged in the slide groove. When there is multi-directional vibration energy, on the one hand, the energy can be dissipated through the deformation of the body, and on the other hand, the multi-directional vibration energy can be converted into the movement of the slider for energy dissipation, thereby further reducing the vibration energy, and absorbing and consuming the seismic energy through multiple composite energy dissipation and deformation, so that the assembled beam-column node has better seismic resistance, thereby ensuring the reliability of the structure under sudden multi-directional composite seismic loads.
