Description

Technical Field

[0001] This invention relates to the technical field of seismic-resistant structural systems in civil engineering, specifically to a modular arrangement structure for reducing local room seismic acceleration. Background Technology

[0002] In recent years, in addition to traditional seismic design, various energy-dissipating and vibration-damping devices and new structural systems have received increasing attention from the academic and engineering communities. These include energy-dissipating vibration-damping technologies using dampers, seismic isolation technologies using seismic isolation bearings, frequency-modulated vibration reduction technologies using vibration absorbers, as well as self-resetting structures and swaying structures. Actively addressing these earthquake disasters is a crucial task in building urban and rural earthquake prevention and disaster reduction systems. In the field of civil engineering, the concept of earthquake resistance has evolved from "seismic resistance" by increasing cross-sections, to "vibration reduction" by adding energy dissipation, and to "seismic isolation" by isolating ground vibrations. In recent years, it has also been developing towards "recoverable functionality."

[0003] With the continuous development of society and economy and the ongoing progress of seismic technology, people have increasingly higher requirements for the seismic performance of building structures. Currently, structural vibration control technology is being applied more and more in building engineering. The most commonly used vibration control technologies in practice are passive control technologies, mainly including seismic isolation, energy dissipation and damping, and tuned vibration reduction.

[0004] During an earthquake, building structures are subjected to seismic forces, which exert both vertical and horizontal forces, causing seismic acceleration. The national "Seismic Resistance Technical Guidelines Based on Maintaining Normal Building Functionality" currently stipulates floor horizontal acceleration control for key buildings in "two zones and eight categories," particularly emergency command centers, main hospital buildings, emergency shelters, and broadcasting / television buildings. For example, the acceleration of a Class I building under a design earthquake should not exceed 0.2g. However, this requirement is difficult to meet for high-intensity seismic zones, especially high-rise hospital buildings in zones with seismic intensity of 9 degrees. Furthermore, the functionality of modular rooms such as operating rooms and treatment rooms in medical buildings cannot be interrupted during earthquakes. Therefore, it is urgent to introduce seismic isolation technology into acceleration-sensitive rooms, using modular structural layouts and construction to reduce seismic acceleration. Summary of the Invention

[0005] The technical problem to be solved by this invention is that it is difficult to reduce the seismic acceleration experienced by the internal rooms of civil engineering buildings when they are subjected to earthquakes. The purpose of this invention is to provide a modular arrangement structure that reduces the seismic acceleration of local rooms. In this invention, the seismic isolation structure is detachably installed on the main structure without changing the main structure. When the main structure is subjected to an earthquake, the seismic acceleration experienced by the seismic isolation structure and the equipment on the seismic isolation structure is reduced.

[0006] This invention is achieved through the following technical solution:

[0007] A modularly arranged structure for reducing local room seismic acceleration includes: a main structure and a seismic isolation structure;

[0008] The seismic isolation structure includes seismic isolation bearings, frame beams, flexible fillers, prefabricated composite seismic isolation panels, and sound-insulating flexible fillers;

[0009] The seismic isolation bearing and the sound insulation flexible filler are supported by the main structure, and the prefabricated composite seismic isolation plate is used to support the frame beam, which is supported on the seismic isolation bearing.

[0010] The flexible filler is placed between the main structure and the seismic isolation structure to seal the gaps between the sides of the main structure and the sides of the seismic isolation structure.

[0011] The main structure includes: corbels, precast waterproof panels, supporting beams, frame columns, and partition walls;

[0012] The support beam is inserted into the inner side of the frame column, and one end of the support beam is connected to the bracket. The bracket is used to support the front, back, left and right sides of the seismic isolation bearing and the prefabricated waterproof plate.

[0013] The prefabricated waterproof liner supports the remaining part of the seismic isolation bearing, and the prefabricated waterproof liner supports the sound-insulating flexible filler;

[0014] The partition wall is installed on the inner side of the frame column and is integrally formed with the frame column. The partition wall is in close contact with the flexible filler. The flexible filler is used to seal the partition wall and the prefabricated composite seismic isolation plate, the frame column and the prefabricated composite seismic isolation plate, and also to seal the seismic isolation bearing and the support beam. The flexible filler can buffer the horizontal seismic force on the seismic isolation bearing.

[0015] The frame beam extends downwards from the lower end of the four sides of the prefabricated composite vibration isolation plate. The inner side of the frame beam surrounds the outer side of the sound-insulating flexible filler. The lower end of the vibration isolation plate contacts the upper end of the sound-insulating flexible filler. The sound-insulating flexible filler is made of sponge material. A flexible pipe is opened inside the sound-insulating flexible filler, extending to the vibration isolation support and the interior of the prefabricated composite vibration isolation plate. The outer side of the frame beam is in contact with the flexible filler.

[0016] The seismic isolation bearing is used to support the frame beam. Anchors for connecting the frame beam and the seismic isolation bearing are provided inside the frame beam, or the anchors are provided on the upper side of the corbel. The anchors connect to the seismic isolation bearing. The seismic isolation bearing reduces the horizontal and vertical seismic acceleration of the frame beam and the prefabricated composite seismic isolation plate. The sound-insulating flexible filler fills the cavity formed between the frame beam, the prefabricated composite seismic isolation plate and the prefabricated waterproof plate, providing sound insulation and reducing the collision between the seismic isolation structure and the main structure.

[0017] An angle steel is fastened to the upper inner side of the bracket, and the angle steel is supported on the lower end face of the prefabricated waterproof board.

[0018] The thickness of the prefabricated waterproof liner is at least 80 mm.

[0019] The thickness of the flexible filler is at least greater than 100mm, which serves to buffer or reduce the horizontal movement speed of the frame beams and prefabricated composite vibration isolation plates, and avoid collisions with the support beams, frame columns and partition walls.

[0020] The diameter of the seismic isolation bearing is in the range of 200-300mm, and mature stacked rubber bearings can be used. The diameter and number of seismic isolation bearings supporting the seismic isolation structure depend on the weight, bearing capacity and displacement requirements of the seismic isolation structure and must meet the current specifications.

[0021] The main structure has a supporting beam, a frame column and a partition wall. The partition wall is located at the upper end of the supporting beam, and the supporting beam and the partition wall are separated by the frame column.

[0022] The main structure has a corbel and a support beam, which are integrally formed into an "L" shape, and the cross-sectional area of ​​the support beam is larger than that of the corbel.

[0023] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0024] The seismic isolation structure of this invention is detachably installed on the main structure. Without changing the form of the main structure, the seismic isolation structure reduces the acceleration caused by earthquakes on the main structure. This reduces the seismic acceleration experienced by important or functional equipment within the room, allowing for uninterrupted operation of this equipment. Specifically, the seismic isolation bearings (elastic components) and the sound-insulating flexible filler of the seismic isolation structure are connected and supported by the main structure. The seismic isolation bearings support the frame beams and the prefabricated composite seismic isolation plates. Under earthquake action, due to the horizontal and vertical forces acting on the main structure, the horizontal elasticity of the seismic isolation bearings and the horizontal buffering effect of the sound-insulating flexible filler reduce the impact on the frame beams, prefabricated composite seismic isolation plates, and the upper part of the room. The seismic acceleration experienced by the equipment inside the room is reduced by the vertical elastic effect of the seismic isolation bearing itself and the connection between the seismic isolation bearing and the frame beam and the main structure. The seismic isolation bearing itself reduces the vertical seismic acceleration experienced by the frame beam and the prefabricated composite seismic isolation plate and the equipment in the room above it. The flexible filler is placed between the main structure and the seismic isolation structure. Under the action of horizontal force, the main structure is subjected to horizontal vibration. The buffering effect of the flexible filler reduces the collision between the seismic isolation bearing, the frame beam and the prefabricated composite seismic isolation plate and the main structure. The vertical and horizontal seismic acceleration experienced by the equipment in the upper part of the frame beam and the prefabricated composite seismic isolation plate is reduced. Therefore, the seismic isolation structure of the present invention reduces the seismic acceleration experienced by the frame beam and the prefabricated composite seismic isolation plate and the equipment in the room above it.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0033] Example 1

[0034] like Figure 1-2 As shown, this embodiment provides a modular arrangement structure for reducing local room seismic acceleration, including: a main structure and a seismic isolation structure;

[0035] The seismic isolation structure includes a seismic isolation bearing 1, a frame beam 3, a flexible filler 4, a prefabricated composite seismic isolation plate 5, and a sound-insulating flexible filler 6.

[0036] The main structure includes: corbel 7, angle steel 8, prefabricated waterproof slab 9, support beam 10, frame column 11, and partition wall 12;

[0037] The support beam 10 is inserted into the inner side of the frame column 11. One end of the support beam 10 (i.e., the inner end of the frame column 11) is connected to a bracket 7. The seismic isolation bearing 1 and the sound insulation flexible filler 6 are supported by the main structure. That is, the bracket 7 is used to support part of the seismic isolation bearing 1 and the four sides of the prefabricated waterproof plate 9. The prefabricated waterproof plate 9 supports the remaining part of the seismic isolation bearing 1 and the sound insulation flexible filler 6. The seismic isolation bearing 1 is located between the outer sides of the flexible filler 4 and the sound insulation flexible filler 6. The seismic isolation bearing 1 is movable in the horizontal direction. The prefabricated composite seismic isolation plate 5 is used to support the frame beam 3. The frame beam 3 is supported on the seismic isolation bearing 1.

[0038] The partition wall 12 (similar to a combination of sound-insulating flexible filler 6 and prefabricated waterproof board 9, the partition wall 12 provides sound insulation and prefabricated waterproofing in the vertical direction) is installed on the inner side of the frame column 11. The partition wall 12 is integrally formed with the frame column 11. The partition wall 12 is in close contact with the flexible filler 4. The flexible filler 4 is installed between the main structure and the seismic isolation structure and is used to seal the sides of the main structure and the seismic isolation structure. That is, the flexible filler 4 is used to seal the partition wall 12 and the prefabricated composite seismic isolation board 5, the frame column 11 and the prefabricated composite seismic isolation board 5, and the seismic isolation support 1 and the support beam 10.

[0039] The frame beam 3 extends downwards from the lower end surfaces of the four sides (front, back, left, and right) of the prefabricated composite vibration isolation plate 5. The inner side of the frame beam 3 surrounds the outer sides of the sound-insulating flexible filler 6. The lower end surface of the vibration isolation plate 5 contacts the upper end surface of the sound-insulating flexible filler 6, and the sound-insulating flexible filler 6 contacts the upper end surface of the prefabricated waterproof plate 9. The sound-insulating flexible filler 6 is made of sponge material and fills the cavity formed between the frame beam 3, the prefabricated composite vibration isolation plate 5, and the prefabricated waterproof plate 9. Figure 3 and Figure 2 The difference is Figure 3 A flexible pipe 16 is opened inside the sound-insulating flexible filler 6. The flexible pipe 16 is opened to the vibration isolation support 1 and the interior of the prefabricated composite vibration isolation plate 5. The flexible pipe 16 can allow air to enter and exit at the contact position between the sound-insulating flexible filler 6 and the prefabricated composite vibration isolation plate 5. The sound-insulating flexible filler 6 plays the role of sound insulation and vibration isolation of the vibration isolation structure (specifically described in embodiment 4). The outer side of the frame beam 3 is in contact with the flexible filler 4.

[0040] The seismic isolation bearing 1 is used to support the frame beam 3. The diameter of the seismic isolation bearing 1 is in the range of 200-300mm. The frame beam 3 has anchors 2 inside for fastening the frame beam 3 structure. Anchors 2 can also be set on the upper side of the bracket 7. That is to say, the anchors 2 inside the frame beam 3 improve the stress strength of the frame beam 3 and prevent the frame beam 3 from falling apart. The anchors 2 on the frame beam 3 or on the bracket 7 are connected to the seismic isolation bearing 1. The seismic isolation bearing 1 reduces the horizontal and vertical seismic acceleration of the frame beam 3 and the prefabricated composite seismic isolation plate 5. The flexible filler 4 fills the gaps and provides sound insulation. To reduce the collision between the seismic isolation structure and the main structure, the lower end of the seismic isolation bearing 1 is fixed to the corbel 7, and the upper end of the seismic isolation bearing 1 is connected to the frame beam 3 of the prefabricated composite seismic isolation plate 5. Therefore, it is necessary to reserve movement space between the prefabricated composite seismic isolation plate 5 and the supporting beam 10, frame column 11 and partition wall 12. The flexible filler 4 is filled in the 100mm material filling gap 14 to reserve the movement space of the prefabricated composite seismic isolation plate 5 under earthquake. The reason for adding the flexible filler 4 is that the flexibility of the flexible filler 4 provides limited resistance to the structural movement of the seismic isolation bearing 1, and at the same time plays a role in buffering and preventing the seismic isolation bearing 1 from colliding with the supporting beam 10, frame column 11 and partition wall 12.

[0041] The seismic isolation bearing 1 adopts a mature laminated rubber bearing. The seismic isolation bearing 1 itself is an elastic element and can make elastic movements in the horizontal or vertical directions. In addition, the buffering effect of the flexible filler 4 can prevent the seismic isolation bearing 1 from colliding with the support beam 10, frame column 11 and partition wall 12. The buffering effect of the flexible filler 4 on the seismic isolation bearing 1 and the elastic effect of the seismic isolation bearing 1 itself can reduce the horizontal seismic acceleration of the structure or equipment 13 set on the seismic isolation bearing 1 under seismic action. The vertical seismic reduction effect of the seismic isolation bearing 1 is because it is an elastic element. The vertical stiffness of the seismic isolation bearing 1 is much lower than that of concrete. The seismic isolation bearing 1 itself can make vertical elastic movements, which can reduce the vertical seismic acceleration of the precast composite seismic isolation plate 5.

[0042] An angle steel 8 is fastened to the inner upper end of the bracket 7, and the angle steel 8 is supported on the lower end face of the prefabricated waterproof plate 9.

[0043] The thickness of the prefabricated waterproof liner 9 is at least greater than 80mm, which provides sufficient support for the prefabricated waterproof liner 9, and the prefabricated waterproof liner 9 itself can also be waterproof.

[0044] The thickness of the flexible filler 4 is at least greater than 100mm, which buffers or reduces the horizontal movement speed of the frame beam 3 and the prefabricated composite vibration isolation plate 5, and avoids collision with the support beam 10, frame column 11 and partition wall 12.

[0045] The main structure has a supporting beam 10, a frame column 11 and a partition wall 12. The partition wall 12 is located at the upper end of the supporting beam 10. The supporting beam 10 and the partition wall 12 are separated by the frame column 11. The room at the upper end of the frame beam 3 and the prefabricated composite vibration isolation plate 5 is waterproofed and soundproofed by the lateral partition wall 12, the lower sound-insulating flexible filler 6 and the prefabricated waterproof plate 9.

[0046] The main structure has a corbel 7 and a support beam 10. The corbel 7 and the support beam 10 are integrally formed into an "L" shape. The cross-sectional area of ​​the support beam 10 is larger than that of the corbel 7. The support beam 10 has sufficient strength within the frame column 11 to allow the corbel 7 to support the low-weight seismic isolation structure. The material of the corbel 7 is saved.

[0047] Example 2

[0048] like Figure 2 , 4As shown, frame columns 11 are located at the four corners of support beams 10. The four support beams 10 and frame columns 11 are interlocked to form the frame of the main structure. Four partition walls 12 each form the four walls of the room along the edge of each support beam 10. Precast waterproof panels 9 support the frame beams 3 and precast composite seismic isolation panels 5 through corbels 7, forming what is equivalent to the floor of the room. This room is assembled and constructed separately on the building structure; therefore, this room is a partial room of the building structure, such as... Figure 2 and Figure 4 The difference lies in the number of seismic isolation bearings 1 and angle steel 8 installed in this column on the room plane.

[0049] like Figure 1-4 As shown, equipment 13 for operation can be placed or fixed on the upper surface of the prefabricated composite seismic isolation plate 5. Material filling gaps 14 are formed between the support beam 10, frame column 11, partition wall 12, seismic isolation bearing 1, and frame beam 3. Flexible filler 4 is formed by filling the material filling gaps 14 starting from the upper surface of the corbel 7. The flexible filler 4 is also formed along the edge of the four partition walls 12. The filling of the flexible filler 4 can connect and seal the outer peripheral wall of the seismic isolation bearing 1, the outer peripheral wall of the prefabricated composite seismic isolation plate 5, the corbel 7, the support beam 10, the frame column 11, and the partition wall 12. Sliding doors 15 are installed on the four partition walls 12. Opening the sliding doors 15 allows access to the local room.

[0050] Additionally, notches can be made at the corners and edges of the sound-insulating flexible filler 6 (in conjunction with...). Figure 1-4 As shown, the outer peripheral wall of the notch of the sound-insulating flexible filler 6 surrounds the outer peripheral wall of the seismic isolation bearing 1, and the remaining outer peripheral wall of the seismic isolation bearing 1 that is not surrounded contacts the flexible filler 4. This allows the seismic isolation bearing 1 to move in a limited manner, reducing the acceleration of the seismic isolation structure under seismic action without colliding with the main structure.

[0051] Example 3

[0052] Since the upper end face of the angle steel 8 is welded to the lower end face of the precast waterproof plate 9, and the bracket 7 is also welded to the lower end face of the precast waterproof plate 9, the outer end face of the angle steel 8 is welded to the inner side of the bracket 7. The angle steel 8 is on the inner upper side of the bracket 7. The frame beam 3 and the precast composite vibration isolation plate 5 can be tightly attached to the sound insulation flexible filler 6. The precast waterproof plate 9 and the sound insulation flexible filler 6 can be tightly attached. The outer peripheral wall of the vibration isolation bearing 1 can be tightly attached to the outer peripheral wall of the sound insulation flexible filler 6.

[0053] This invention addresses the issue of partial rooms being subjected to earthquakes via frame columns 11. Frame columns 11 experience both horizontal and vertical forces, as do the main structure and the seismic isolation structure. Seismic isolation bearings 1 also experience both horizontal and vertical forces. The elasticity of the seismic isolation bearings 1, combined with their relatively low horizontal and vertical stiffness, effectively reduces the horizontal and vertical seismic acceleration of the seismic isolation structures, such as the frame beams 3, the prefabricated composite seismic isolation plates 5, and their upper equipment 13. The buffering effect of the flexible filler 4 reduces the collision between the seismic isolation bearings 1, the frame beams 3, the prefabricated composite seismic isolation plates 5, and the main structure. This comprehensive solution addresses the technical problem of reducing seismic acceleration in medical buildings after an earthquake.

[0054] The device 13 is placed or fixed on the upper end of the prefabricated composite seismic isolation plate 5. When the seismic acceleration experienced by the prefabricated composite seismic isolation plate 5 is reduced, the device 13 does not need to stop operating or running, that is, the device 13 can run continuously.

[0055] In addition, such as Figure 1 , 3 As shown, the corbel 7 is a concrete corbel or a steel corbel. When the support beam 10 is a steel structure, only a steel corbel can be used. When the support beam 10 is a concrete structure, a concrete corbel extending from the support beam 10 is used. The seismic isolation bearing 1 and the sound insulation flexible filler 6 are existing elastic components. The precast waterproof board 9 is also a common waterproof board. The flexible filler 4 can be an elastic plastic or rubber material or a sponge material. The partition wall 12 is an existing new type of environmentally friendly sound insulation and water-proof filler wall, and it is advisable to use a flexible connection with the main structure.

[0056] Example 4

[0057] The structural device of the present invention is suitable for high-rise hospital buildings in high-intensity seismic zones, especially in seismic zones of intensity 9, and can meet the requirements for reducing seismic acceleration under seismic fortification.

[0058] A seismic isolation structure is arranged on the main structure. The combination of the seismic isolation structure and the main structure serves as the structure of a local room, forming a "room within a room" structure. Precast waterproof panels 9 are installed at the lower end of the seismic isolation structure and on the corbel 7 for waterproofing, fireproofing, and heat insulation. Sound-insulating flexible filling material 6 is installed between the precast composite seismic isolation panel 5 and the precast waterproof panel 9, which can isolate room noise, replace floating floor slabs, and ensure the normal operation of important equipment.

[0059] This invention addresses the technical problem of interrupted operation of important or functional equipment in a room due to excessive acceleration during an earthquake, without altering the main structural form. By incorporating a seismic isolation structure into the main structure, the invention reduces the acceleration of the isolation structure under seismic action, ensuring uninterrupted operation of important or functional equipment within the room.

[0060] In the seismic isolation structure of the present invention, the floor slab adopts a thick prefabricated composite seismic isolation plate, and the prefabricated waterproof slab installed below it also adopts a steel truss floor deck, which can improve the component assembly rate of the overall structure.

[0061] A sound-insulating flexible filler is installed between the prefabricated composite vibration isolation slab and the 80mm prefabricated waterproof slab, so the equipment has good sound insulation and vibration isolation capabilities in the room and can replace the floating floor slab.

[0062] This invention, without altering the main structural layout, incorporates a seismic isolation structure within the main structure to function as a partial room, forming a "room within a room" structure. This room structure employs a large floor slab plus a frame beam system. The frame beam supports prefabricated composite seismic isolation slabs and seismic isolation bearings. Under seismic loading, the acceleration of the seismic isolation structure in important rooms is significantly reduced, effectively protecting the equipment in these special rooms. A seismic isolation layer is formed between the prefabricated composite seismic isolation slab and an 80mm prefabricated waterproof slab placed under the corbel. Sound-insulating flexible fillers are installed within this isolation layer, thus providing the equipment room with excellent sound and seismic isolation capabilities, replacing floating floor slabs.

[0063] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
