Description

Technical Field

[0001] The present invention belongs to the technical field of building structure engineering, and in particular relates to a steel structure assembled building with a shock-absorbing function. Background Art

[0002] With the rapid advancement of building industrialization, steel structure prefabricated buildings have been widely used in residential, public buildings and other fields due to their advantages such as light weight, high strength, short construction period and green environmental protection. Steel structure prefabricated buildings have greatly improved construction efficiency and reduced on-site wet operations through factory prefabricated components and on-site assembly and connection, which meets the requirements of modern buildings for energy conservation, environmental protection and quality control.

[0003] A Chinese invention patent publication number CN112982826A discloses a steel structure prefabricated building with a shock-absorbing function, comprising an upper support and a lower support, the top center of the lower support and the bottom center of the upper support are connected to a load-bearing block, a shock absorber is arranged between the upper support and the lower support, and the upper and lower ends thereof are connected to the load-bearing block, two adjacent load-bearing blocks are fixedly connected by a load-bearing spring, the top of the lower support is evenly connected to the lower support rod in an annular manner, the bottom end of the upper support is evenly connected to the upper support rod in an annular manner, the upper support rod and the lower support rod are rotatably connected by a rotating shaft, and the two adjacent rotating shafts are connected by an annular spring. The center of the rotating shaft is horizontally connected to a sliding support rod, and the sliding support rod is slidably connected to a horizontal limit block, and the horizontal limit block is connected to the outer wall of the middle of the shock absorber through a fixed block. The horizontal limit block is hollow inside and a horizontal spring matching it is arranged. The device can buffer the shaking up and down and left and right, front and back, and provide basic shock-absorbing function for prefabricated buildings.

[0004] However, the above-mentioned technologies often have the following defects: the shock absorbers, springs and other components are concentrated between the upper and lower pillars, making the nodes a stress concentration area. Under long-term vibration or strong earthquakes, these connection nodes may become loose and deformed due to continuous stress, thereby affecting the overall structural strength of the steel structure prefabricated building and even causing safety hazards. In addition, the horizontal limit blocks, fixed blocks and other components are connected to the middle outer wall of the shock absorber, which increases the complexity of the local structure and may interfere with the modular design of the building and the standardized production of components.

[0005] To this end, the present invention provides a steel structure assembled building with shock absorption function. Summary of the Invention

Groove, the inner top wall of the rivet groove is movably connected to the angle of the upper end face of the L-shaped square tube column, and the bottom of the two side surfaces of the vertical tube column are provided with a concave edge groove, the inner side wall of the concave edge groove is fixedly connected to the stable end, and the inner side wall of the vertical tube column is sleeved with a column adding kit, the lower surface of the column adding kit is provided with a shock-absorbing square pad, the inner arc surface of the shock-absorbing square pad is provided with a rubber cone head, and a deformation arc surface is provided between the rubber cone head and the shock-absorbing square pad, honeycomb holes are provided on the circumferential end faces of the column adding kit, and the column adding kit is provided with an outer rib abutment end near the top of the deformation arc surface.

[0008] There are two vertical tubular columns, which are mirror-connected to the top and bottom of the joint assembly. The inner arc surfaces of the two vertical tubular columns are connected to a column adding kit, and the rubber cone heads at the bottom of the two column adding kits are placed opposite each other.

[0009] The inner arc surface of the rubber cone head is connected with a buffer bracket, the upper surface of the buffer bracket is provided with a conical column, the upper surface of the conical column is provided with a through hole, the conical column is connected to the rubber cone head through the through hole at the top, and the lower surface of the buffer bracket close to the conical column is provided with an outward end.

[0010] One end of the outward-facing end extends into the hollow structures on both sides of the L-shaped square tube column, and an inner lining butt end is provided at the extension of one end of the outward-facing end. The upper surface of the inner lining butt end is provided with a buffer abutment surface A, and the lower surface of the inner lining butt end is provided with a buffer abutment surface B.

[0011] The upper end surface of the buffer abutment surface A is placed on the inner top wall of the L-shaped square tube column, the lower end surface of the buffer abutment surface B is placed on the inner bottom wall of the L-shaped square tube column, the buffer bracket is placed in the middle of the two vertical tube columns, and the conical column at the top end of the buffer bracket abuts against the inner side wall of the joint assembly.

[0012] A shock-absorbing plate is fixedly installed on the upper surface of the conical column. Connecting flat ends are provided at the four corners of the upper surface of the shock-absorbing plate. Shock-absorbing soft balls are fixedly installed on the upper and lower surfaces of the connecting flat ends.

[0013] A rubber auxiliary pad is provided on the upper surface of the shock-absorbing soft ball, and the upper and lower surfaces of the rubber auxiliary pad are both attached to the bottom surface of the deformed arc surface. A fixing hole is opened in the middle of the upper surface of the shock-absorbing plate.

[0014] The upper surface of the fixing hole is sleeved on the outer arc surface of the rubber cone head. The shock-absorbing plate is provided with a weight-reducing groove away from the fixing hole. The number of the shock-absorbing soft balls is several and symmetrically distributed with the shock-absorbing plate as the center point.

[0015] The lower surface of the shock-absorbing soft ball at the bottom is connected to an inner end cross beam, and hinged ends are provided on both sides of one side surface of the inner end cross beam.

The buffer bracket, with the force decomposition effect of the tapered columns and the deformation adaptation of the outward end, guides the remaining vibration force to the foundation frame, achieving the ultimate dissipation of energy, significantly reducing the building's vibration response in strong earthquakes and reducing the risk of structural cracking, deformation, and even collapse.

[0017] 2. By combining the hollow structure of the L-shaped square tube column with the rigid support of the vertical tube column, and coordinating the multi-directional constraints of components such as the outer rib abutment end of the column addition kit and the outward extension end of the buffer bracket, the structure can maintain a stable shape under long-term use and vibration loads, reducing fatigue damage to components caused by excessive local stress.

[0018] 3. The close fit of the column-adding kit and the vertical column, the secure connection of the shock-absorbing plate and the rubber cone head through the fixing holes, and the multi-directional abutment of the buffer bracket and the L-shaped square column ensure that the vibration force can be evenly distributed to each component, reducing the deformation or fracture of the component caused by local excessive force. At the same time, the symmetrically distributed shock-absorbing soft balls on the shock-absorbing plate and the synergistic effect of the inner end beam enhance the overall rigidity and anti-lateral displacement ability of the structure, so that the building maintains a stable shape during vibration and improves the safety redundancy of the overall structure.

[0019] 4. By docking the joint assembly with the L-shaped square pipe column and the vertical pipe column, there is no need for complicated on-site debugging. The assembly can be completed by simple methods such as plug-in, socket connection, and fixed connection, which reduces a large amount of on-site construction work of traditional buildings and greatly shortens the construction period.

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1 、 Figure 2 and Figure 3As shown, the embodiment of the present invention includes an L-shaped square tube column 1, an upper end surface at the angle of the L-shaped square tube column 1 is provided with a plug-in groove, the inner arc surface of the L-shaped square tube column 1 is a hollow structure, and a joint assembly 2 is connected through the plug-in groove of the inner arc surface of the L-shaped square tube column 1, a notch 201 is provided on one end surface of the joint assembly 2, a stabilizing end 202 is provided at the edge of the inner side wall of the joint assembly 2, a vertical tube column 3 is fixedly plugged on the upper surface of the joint assembly 2, a rivet groove 301 is provided at the front angle of the vertical tube column 3, and the inner top wall of the rivet groove 301 is movably abutted against the angle of the upper end surface of the L-shaped square tube column 1 The bottom of both side surfaces of the vertical column 3 is provided with a concave edge groove 302, the inner side wall of the concave edge groove 302 is fixedly connected to the stable end 202, the inner side wall of the vertical column 3 is sleeved with a column adding kit 4, the lower surface of the column adding kit 4 is provided with a shock-absorbing square pad 401, the inner arc surface of the shock-absorbing square pad 401 is provided with a rubber cone head 402, and a deformation arc surface 403 is provided between the rubber cone head 402 and the shock-absorbing square pad 401, honeycomb holes 404 are provided on the circumferential end surface of the column adding kit 4, and an outer rib abutment end 405 is provided on the column adding kit 4 near the top of the deformation arc surface 403.

[0025] The L-shaped structure provides a stable bottom bearing frame for the entire building. The hollow inner arc surface design not only reduces its own weight, but also provides installation space for the buffer bracket 5 shock-absorbing components, so that the force generated by vibration can be dispersed and transmitted through the internal structure. The plug-in groove on the upper end face at the angle is the connection interface with the joint assembly 2. Through the through-fitting with the joint assembly 2, the load of the upper structure is stably transferred to the foundation. At the same time, with the help of its own rigidity, it resists horizontal and vertical vibration impact forces, providing a rigid support foundation for the entire structural system. The joint assembly 2 is the core hub connecting the L-shaped square tube column 1 and the vertical tube column 3, and plays the role of force transfer and distribution. It penetrates and is connected to the plug-in groove of the L-shaped square tube column 1, and is fixedly connected to the concave edge groove 302 at the bottom of the vertical tube column 3 through the stable end 202 of the inner wall edge, forming a rigid node, ensuring that the load transmitted by the vertical tube column 3 can be efficiently transmitted to the L-shaped square tube column 1. At the same time, when encountering vibration, the joint assembly 2 can evenly disperse the vertical force and horizontal force transmitted from the vertical tube column 3 to the L-shaped square tube column 1, reducing local stress concentration and improving the anti-vibration stability of the structure. The vertical tube column 3 is fixedly plugged into the top and bottom of the joint assembly 2 to form a vertical support that runs through from top to bottom. The support has its inner top wall of the rivet groove 301 at the front angle movably abutted against the angle of the upper end face of the L-shaped square tube column 1, further strengthening the connection with the L-shaped square tube column 1. During vibration, this abutment relationship can be used to limit the transition displacement, playing a preliminary limiting and buffering role. The column-adding kit 4 sleeved on the inner wall of the vertical tube column 3 can consume vibration energy through its own shock-absorbing square pad 401 and deformation arc surface 403 structure, and the vertical tube column 3 itself serves as a force transmission channel, transmitting the load of the upper structure and the force generated by vibration to the joint assembly 2 and the L-shaped square tube column 1. At the same time, with the help of its own rigidity and the synergistic effect of the elastic deformation of the column-adding kit 4, vertical and horizontal vibration buffering is achieved.

[0026] like Figure 4 and Figure 5 As shown, there are two vertical tube columns 3, which are mirror-inserted into the top and bottom of the joint assembly 2. The inner arc surfaces of the two vertical tube columns 3 are connected with the column adding kit 4. The rubber cone heads 402 at the bottom of the two column adding kits 4 are placed opposite to each other. The inner arc surface of the rubber cone head 402 is penetrated by a buffer bracket 5. The upper surface of the buffer bracket 5 is provided with a conical column 501. The upper surface of the conical column 501 is provided with a through hole. The conical column 501 is connected to the rubber cone head 402 through the through hole at the top. The lower surface of the buffer bracket 5 close to the conical column 501 is provided with an outward end 502.

[0027] The column adding kit 4 is sleeved on the inner arc surface of the vertical pipe column 3, and the outer rib abutment end 405 near the top of the deformed arc surface 403 is tightly fitted with the inner wall of the vertical pipe column 3. This fitting relationship ensures that the column adding kit 4 can synchronously bear the vibration load transmitted by the vertical pipe column 3, avoiding the concentration of vibration impact caused by the gap. The rubber cone heads 402 at the bottom of the two column adding kits 4 are placed opposite to each other, forming symmetrical force application points in the upper and lower parts, providing a force transmission interface for the intermediate buffer structure, so that the vibration energy can be diffused to the internal structure through the rubber cone head 402. The shock-absorbing square pad 401 on the lower surface of the column kit 4 is made of elastic material. When the vertical pipe column 3 is subjected to vertical or horizontal vibration, the shock-absorbing square pad 401 first undergoes elastic deformation, and consumes part of the vibration energy through the friction of the material itself, playing a preliminary buffering role. The deformation arc surface 403 between the rubber cone head 402 inside and the shock-absorbing square pad 401 acts as an energy dissipation structure. When the vibration load is transmitted to the rubber cone head 402, the deformation arc surface 403 will bend, stretch, etc. due to the force, converting the mechanical energy of the vibration into In order to release heat energy and disperse stress by changing the curvature of the arc surface, structural damage caused by local excessive force is avoided. The honeycomb holes 404 on the side end faces of the column adding kit 4 further enhance the shock absorption effect. The honeycomb structure has the characteristics of lightweight and high energy absorption. When the vibration wave is transmitted to the column adding kit 4 through the vertical pipe column 3, the hole wall of the honeycomb hole 404 will be slightly squeezed and deformed, and the vibration energy will be further dissipated through the interaction between the holes. At the same time, the weight of the column adding kit 4 is reduced, avoiding additional burden on the overall structure. In addition, the rubber cone head 402 is not only a force transmission node, but its own rubber material properties can also play a shock-absorbing role. When it contacts the components between the conical column 501 of the buffer bracket 5 and the fixing hole 604 of the shock-absorbing plate 6, the rubber cone head 402 will adapt to the forces in different directions through elastic deformation, and disperse the concentrated load into a uniform surface load, reducing the impact on adjacent components. At the same time, the interaction between the rubber auxiliary pad 603 on the shock-absorbing plate 6 and the deformed arc surface 403 forms a multi-level buffering system to enhance the ability to resist complex vibrations.

[0028] The column-adding kit 4 constructs an efficient shock-absorbing mechanism inside the vertical pipe column 3 through the initial buffering of the shock-absorbing square pad 401, the energy dissipation of the deformed arc surface 403, the secondary energy absorption of the honeycomb hole 404, and the force transmission and dispersion of the rubber cone head 402. It works in conjunction with other components to effectively reduce the impact of vibration on the steel structure prefabricated building.

[0029] like Figure 4 and Figure 6 As shown, one end of the outward-facing end 502 extends into the hollow structures on both sides of the L-shaped square tube column 1, and an inner lining butt end 503 is provided at the extension of one end of the outward-facing end 502. The upper surface of the inner lining butt end 503 is provided with a buffering butt surface A504, and the lower surface of the inner lining butt end 503 is provided with a buffering butt surface B505. The upper end surface of the buffering butt surface A504 is placed on the inner top wall of the L-shaped square tube column 1, and the lower end surface of the buffering butt surface B505 is placed on the inner bottom wall of the L-shaped square tube column 1. The buffer bracket 5 is placed in the middle of the two vertical tube columns 3, and the conical column 501 at the top of the buffer bracket 5 abuts against the inner side wall of the joint assembly 2. A shock-absorbing plate 6 is fixedly installed on the upper surface of the conical column 501. Connecting flat ends 601 are provided at the four corners of the upper surface of the shock-absorbing plate 6, and shock-absorbing soft balls 602 are fixedly installed on the upper and lower surfaces of the connecting flat end 601.

[0030] The top conical column 501 of the buffer bracket 5 abuts against the inner wall of the joint assembly 2, and the outward end 502 at the bottom extends into the hollow structure on both sides of the L-shaped square tube column 1. Through the upper-connected and lower-expanded layout, the vertical vibration force is guided from the upper structure to the basic frame, while reserving space for horizontal vibration buffering. In terms of force dispersion and buffering, the buffering abutment surface A504 on the upper surface of the lining abutment 503 at the extension of the outward end 502 contacts the inner top wall of the L-shaped square tube column 1, and the buffering abutment surface B505 on the lower surface contacts the inner bottom wall. When encountering vertical vibration, the buffering abutment surface A504 and the buffering abutment surface B505 convert part of the vertical force into horizontal dispersion force through mutual compression with the inner wall of the L-shaped square tube column 1, thereby avoiding concentrated force transmission. At the same time, the lining abutment 503 itself can undergo slight deformation, absorbing part of the vibration energy through the elastic properties of the material, and playing a preliminary buffering role. For horizontal vibrations, the outward end 502 of the buffer bracket 5 can adapt to the horizontal displacement of the structure by slightly swinging in the hollow structure of the L-shaped square tube column 1. The conical structure of the conical column 501 decomposes the lateral load into a component force along the conical surface under the action of horizontal force, and transmits it to the rubber cone head 402 and the joint assembly 2. Combined with the elastic deformation of the rubber cone head 402 and the rigid constraint of the joint assembly 2, step-by-step buffering of horizontal vibrations is achieved. In addition, the buffer bracket 5 is located in the middle of the two vertical tube columns 3, so that it can simultaneously bear the force transmitted by the vertical tube columns 3 on both sides, and integrate the dispersed loads through the integrity of its own structure to avoid structural deflection caused by excessive force on one side. The synergistic effect of the buffer bracket 5 and other components further enhances the shock absorption effect. The connection between its top and the rubber cone head 402 allows the vibration force to first pass through the elastic buffer of the rubber material during the transmission process, and the bottom abuts against the L-shaped square tube column 1, with the help of the rigid dispersion force of the basic frame; at the same time, the connection between the conical column 501 and the shock absorbing plate 6 transmits the remaining vibration force to the shock absorbing soft ball 602 on the shock absorbing plate 6, forming a multi-stage shock absorption chain from the bracket to the end buffer and then to the soft ball energy consumption, which greatly improves the ability to resist complex vibrations.

[0031] like Figure 4 and Figure 7As shown, one end of the outward-facing end 502 extends into the hollow structures on both sides of the L-shaped square tube column 1, and an inner lining butt end 503 is provided at the extension of one end of the outward-facing end 502. The upper surface of the inner lining butt end 503 is provided with a buffering butt surface A504, and the lower surface of the inner lining butt end 503 is provided with a buffering butt surface B505. The upper end surface of the buffering butt surface A504 is placed on the inner top wall of the L-shaped square tube column 1, and the lower end surface of the buffering butt surface B505 is placed on the inner bottom wall of the L-shaped square tube column 1. The buffer bracket 5 is placed in the middle of the two vertical tube columns 3, and the conical column 501 at the top of the buffer bracket 5 abuts against the inner side wall of the joint assembly 2. A shock-absorbing plate 6 is fixedly installed on the upper surface of the conical column 501. Connecting flat ends 601 are provided at the four corners of the upper surface of the shock-absorbing plate 6, and shock-absorbing soft balls 602 are fixedly installed on the upper and lower surfaces of the connecting flat end 601.

[0032] The fixing hole 604 in the middle is sleeved on the outer arc surface of the rubber cone head 402 to form an intermediate hub structure connecting the lower buffer bracket 5 to the upper column kit 4. This connection method ensures that the vibration force transmitted by the buffer bracket 5 can directly act on the shock absorbing plate 6. At the same time, with the help of the close fit between the fixing hole 604 and the rubber cone head 402, the excessive displacement of the shock absorbing plate 6 is limited, providing a basis for stable energy consumption. The damping balls 602 fixed to the upper and lower surfaces of the connecting flat ends 601 at the four corners of the damping plate 6 are made of a highly elastic rubber material with deformation recovery capabilities. When the vibration force is transmitted to the damping plate 6 through the conical columns 501, the damping balls 602 first absorb part of the energy through compression and deformation, converting the mechanical energy of the vibration into frictional heat energy within the material for release. At the same time, several damping balls 602 are symmetrically distributed around the damping plate 6, which can evenly distribute the concentrated load to multiple points of action, avoiding damage to components caused by excessive local stress. The rubber auxiliary pad 603 on the upper surface of the shock-absorbing soft ball 602 further enhances the buffering effect. The rubber auxiliary pad 603 is attached to the bottom surface of the deformed arc surface 403 of the column adding kit 4. When the column adding kit 4 is deformed due to vibration, the rubber auxiliary pad 603 forms a secondary buffer through mutual squeezing and friction with the deformed arc surface 403, which not only reduces the direct force on the shock-absorbing soft ball 602, but also dissipates more vibration energy through double elastic contact. The inner end cross beam 605 at the bottom of the shock-absorbing plate 6 is connected to the shock-absorbing soft ball 602 through the hinge end 606. The two inner end cross beams 605 are symmetrically distributed, which can integrate and transmit the dispersed vibration force and enhance the integrity of the structure. When encountering horizontal or vertical vibration, the inner end cross beam 605 can swing slightly with the deformation of the shock-absorbing soft ball 602, guiding part of the force to spread horizontally, and cooperating with the outward end 502 of the buffer bracket 5 and the hollow structure of the L-shaped square tube column 1 to form a synergistic mechanism from vertical buffering to horizontal dispersion.

[0033] like Figure 8As shown, in the initial transmission stage of the vibration load, the external vibration first acts on the vertical column 3, and the vertical column 3 transmits the vibration force to the column-adding kit 4 sleeved on its inner arc surface. The shock-absorbing square pad 401 of the column-adding kit 4 performs preliminary buffering through elastic deformation. At the same time, the deformed arc surface 403 bends and deforms due to the force, converting part of the vibration energy into heat energy dissipation. At this time, the rubber cone head 402 at the bottom of the column-adding kit 4 acts as a force transmission node, and concentrates the remaining vibration force to the middle shock-absorbing plate 6. The honeycomb holes 404 on the peripheral side further disperse the energy through hole wall extrusion. The shock-absorbing plate 6 acts as an intermediate hub connecting the upper and lower parts, and receives the vibration from the rubber cone head 402 of the column-adding kit 4. After the force is applied, the position of the shock-absorbing ball 602 is stabilized by the close fit of the central fixing hole 604 to avoid excessive displacement. The shock-absorbing soft balls 602 on the flat ends 601 of the four corner connections immediately absorb energy through compression deformation. The symmetrically distributed layout evenly distributes the concentrated load to multiple points of action. At the same time, the rubber auxiliary pads 603 on the upper surface of the shock-absorbing soft ball 602 and the deformed arc surface 403 of the column kit 4 squeeze and rub against each other to form a secondary buffer, which not only reduces the direct force on the shock-absorbing soft ball 602, but also dissipates more energy through double elastic contact. The inner end crossbeam 605 at the bottom of the shock-absorbing plate 6 swings slightly with the deformation of the shock-absorbing soft ball 602, guiding part of the force to the horizontal direction, thereby enhancing the anti-lateral displacement ability of the overall structure. The conical column 501 at the top of the buffer bracket 5 receives the remaining vibration force transmitted by the shock-absorbing plate 6, and decomposes the vertical force into component forces along the conical surface through the conical structure, and disperses them to the rubber cone head 402 and the joint assembly 2. The outward end 502 at the bottom extends into the hollow structure of the L-shaped square tube column 1, and the buffer abutment surface A504 and the buffer abutment surface B505 of the lining abutment end 503 are in contact with the inner top wall and the inner bottom wall of the L-shaped square tube column 1 respectively, further absorbing energy through extrusion deformation during vertical vibration, and adapting to displacement through the swing of the outward end 502 during horizontal vibration, cooperating with the rigid constraint of the L-shaped square tube column 1 to limit excessive deformation. The coordinated transmission of the three goes from multi-level transmission to layered energy dissipation and then to directional guidance. The column kit 4 is responsible for initial buffering and preliminary dispersion of vertical force. The shock-absorbing plate 6 realizes secondary energy dissipation and horizontal force guidance through soft components. The buffer bracket 5 transfers the remaining force to the basic frame structure to complete dissipation. It can not only effectively cope with vertical vibration, but also resist lateral impact through the horizontal force dispersion mechanism, forming all-round shock absorption protection, which greatly improves the structural stability of steel structure prefabricated buildings in complex vibration environments.
