Description

Technical Field

[0001] This application relates to building structures, and more particularly to a cross-joint closed beam structure. Background Technology

[0002] In architectural design and construction, buildings with ultra-long structures, complex shapes, and irregular facades may exhibit non-uniform stress distribution, deformation concentration, or significant seismic torsional effects under seismic loading due to their unique geometry and structural characteristics. This can lead to increased vulnerability of the structure, either locally or overall. To improve seismic performance, the traditional approach is to install seismic joints at appropriate locations, forming multiple relatively regular lateral force-resisting structural units to reduce the transmission and accumulation of seismic forces and ensure the independence and safety of each structural unit under seismic loading. However, the presence of seismic joints affects the continuity and integrity of the building and may limit the layout and function of the interior space, especially for modern buildings that pursue complex and varied interior spaces and floor plans. Therefore, how to improve the continuity and integrity of a building while incorporating seismic joints is a pressing issue that needs to be addressed. Utility Model Content

Unless otherwise stated, "a plurality of" means two or more.

[0035] Before explaining the technical solutions of the embodiments of this application, the concept of the embodiments of this application will be explained first.

[0036] In architectural design and construction, buildings with ultra-long structures, complex shapes, and irregular facades may exhibit non-uniform stress distribution, deformation concentration, or significant seismic torsional effects under seismic loading due to their unique geometry and structural characteristics, leading to increased vulnerability of the structure, either locally or overall. To improve the seismic performance of buildings, a related technology involves setting seismic joints at appropriate locations to form multiple relatively regular lateral force-resisting structural units. In this embodiment, these structural units can be individual buildings. The seismic joint 201 should have sufficient width based on the seismic fortification intensity, type of structural material, structural type, height and elevation difference of the structural units, and potential seismic torsional effects, and the superstructure on both sides should be completely separated. Specifically, the width of the seismic joint 201 should be calculated based on the maximum displacement that the structural unit may experience under the expected maximum seismic loading, thus determining the minimum width of the seismic joint 201. Currently, most building structures incorporate joints to reduce the transmission and accumulation of seismic forces and ensure the independence and safety of each structural unit under seismic loading, while meeting safety, applicability, and economic requirements. For example, under the premise of meeting safety, applicability, and economy, most building structures currently incorporate joint treatment. For instance... Figure 1 As shown, a seismic joint 201 is set between building A and building B, and it can be clearly seen that the seismic joint 201 should extend from the top of the foundation 101 all the way to the roof layer 102 to ensure that the structural unit is independent on all floors.

[0037] However, due to irregular building plans and other reasons, the superstructure on both sides needs to be completely separated, resulting in many building functions being unrealizable or interrupted. The existence of seismic joint 201 affects the continuity and integrity of the building and may also limit the layout and function of the interior space, especially for modern buildings that pursue complex and varied interior spaces and floor plans. Therefore, how to solve the problem of building continuity and integrity is an urgent issue to be addressed.

[0038] In view of this, this application discloses a cross-joint closed beam, which can reconnect the individual buildings of the joint through a ring beam, thereby forming a new overall building function and improving the overall design level.

[0039] To achieve the above objectives, this application discloses a joint-sealing beam, which is installed on the roof of multiple individual buildings with seismic joints 201 between them. The roof is provided with frame columns 307, and the joint-sealing beam includes:

[0040] Frame column 307, with supports provided on frame column 307;

[0041] As a key load-bearing component in the building structure, the 307 frame column can be made of a variety of materials, depending on the building design, functional requirements, cost considerations, and local building codes and standards.

[0042] For example, frame column 307 can be a concrete frame column, a steel frame column, a steel and reinforced concrete hybrid frame column, etc. Each material has its unique performance characteristics and applicable scenarios, and the most suitable material needs to be selected according to the specific needs of the project. During the design process, the sustainability, cost-effectiveness, and environmental impact of the materials also need to be considered.

[0043] In the field of structural engineering, supports play a crucial role. They are the points connecting the structure to the foundation or ground, used to transfer loads from the structure to the ground and control structural displacement. The design and type of supports directly affect the stability and safety of the entire structure.

[0044] For example, the support may be a fixed hinge support 203, a friction pendulum support 204, etc.

[0045] An annular closed beam 202 is connected above the support;

[0046] For example, the mechanical behavior of the annular closed beam 202 differs from that of a conventional beam because it lacks free ends and therefore does not exhibit cantilever effects like ordinary beams. When a load is applied to the annular beam, the force is evenly distributed across the entire ring, thereby reducing local stress concentration and improving the overall stability and load-bearing capacity of the structure. Furthermore, the annular closed beam 202 is better able to resist torsion and bending, making it perform excellently under cyclic or dynamic loads.

[0047] For example, when designing the annular closed beam 202, factors that need to be considered include, but are not limited to:

[0048] Material selection: such as concrete, steel, composite materials, etc. Each material has its specific mechanical properties.

[0049] Load analysis includes static loads, dynamic loads, and forces caused by temperature changes.

[0050] Geometric dimensions: The diameter, thickness, and cross-sectional shape of a ring all affect its load-bearing capacity and stiffness.

[0051] Connection method: The connection between the ring beam and other structural components must be firm and reliable to ensure the stability of the overall structure.

[0052] Construction methods, such as precast or cast-in-place, as well as the construction sequence and methods, will also affect the quality of the final structure.

[0053] The design and construction of the annular closed beam 202 typically require advanced calculation tools and software to accurately simulate load distribution and structural response, ensuring that the structure has sufficient safety margins under various conditions.

[0054] The annular closed beam 202 spans the seismic joints 201 of each of the individual buildings.

[0055] The aforementioned annular cross-joint closed beam can span multiple individual buildings, solving the problem that the upper structures on both sides of the roofs of multiple individual buildings need to be completely separated due to irregular building structure planes, resulting in many building functions being unable to be realized or interrupted, thus improving the continuity and integrity of the building.

[0056] On the other hand, the closed beam in this application embodiment is cleverly applied to the design of the skylight. For example, as... Figure 2 As shown, Figure 2 A schematic diagram of one application of the aforementioned cross-joint closed beam is provided, along with a schematic diagram of its support structure arrangement when the closed beam is used in a skylight. By setting fixed hinge supports 203 and spherical friction pendulum supports 204 on the roof, and constructing a closed annular concrete beam above these supports, a new structure capable of spanning the seismic joint 201 is formed, allowing the originally segmented structural units to be reconnected into a whole.

[0057] This design not only demonstrates the perfect integration of structural engineering and architectural design, but also embodies the design philosophy of pursuing architectural aesthetics and functionality while meeting safety standards, making it a model of modern building technology advancement. By innovatively combining the fixed hinge support 203 and the spherical friction pendulum support 204 with the closed ring beam, the seismic performance and stability of the structure can be effectively improved. This combination can not only withstand vertical loads, but also allow horizontal displacement of the structure through the spherical friction pendulum support, while the fixed hinge support restricts unnecessary angular deformation. The combined use of the closed ring beam with these two types of supports enhances the rigidity and torsional resistance of the overall structure, thereby providing better protection and support under external impacts such as earthquakes. The following details the components of the cross-joint closed beam mentioned in this application example and the function of each component in this embodiment.

[0058] Depend on Figure 2 It is not difficult to see that the roofs of the individual buildings are irregular, and seismic joints 201 are respectively set between buildings 1 and 2, between buildings 2 and 3, between buildings 3 and 4, and between buildings 4 and 1. Figure 3The structural diagram shows that the annular closed beam proposed in this embodiment has a frame column 307 on the roof. The frame column 307 is equipped with supports, including at least one fixed hinge support 203 and at least one friction pendulum support 204. The fixed hinge support 203 and the friction pendulum support 204 are respectively connected to the annular closed beam 202. The annular closed beam 202 spans the seismic joint 201 of each individual building and connects with each support to form a new whole.

[0059] Among them, seismic joint 201, also known as earthquake-resistant joint, is a structural measure set in building design to cope with earthquakes. Its main purpose is to reduce or avoid damage to buildings caused by earthquakes. Seismic joint 201 divides the building into several structurally independent units, allowing these units to deform independently under seismic loads, thereby reducing the interaction forces between structures and avoiding uncoordinated vibrations and potential structural damage to the overall structure.

[0060] For example, seismic joints 201 are typically placed in structural deformation-sensitive parts of a building, such as where the building is too long, has an irregular plan shape, or experiences abrupt changes in structural stiffness or mass.

[0061] By setting seismic joint 201, each part of the building can deform independently, reducing earthquake damage caused by structural integrity.

[0062] Optionally, the width of the seismic joint 201 is determined based on factors such as the building's structural type, height, and seismic intensity, and is usually between 50 and 100 millimeters.

[0063] The installation of seismic joint 201 can improve the seismic performance of buildings, reduce the risk of building damage during earthquakes, and protect the safety of people and property.

[0064] For example, the roof is provided with a parapet wall, and the embedded part is set on the frame column 307 at a position corresponding to the height of the parapet wall. Furthermore, at the height of the parapet wall above the roof, a fixed hinge support 203 and a friction pendulum support 204 for the embedded part are provided at the corresponding position of the frame column 307.

[0065] For example, a parapet wall is a low wall installed at the top edge of a building, typically located around the roof or at the top of a city wall. Its main function is to provide safety protection against falls from heights, and it also serves a certain degree of waterproofing, preventing water from accumulating on the roof and overflowing.

[0066] For example, the height of parapet walls is usually subject to specific regulations. Depending on different building codes, it is generally required to be at least 1.1 meters but not more than 1.5 meters to ensure sufficient safety without affecting the use or aesthetics of the building.

[0067] In building construction, embedded parts are components that are placed in the structure before concrete pouring, for connection during the later installation of other components or facilities. The location of embedded parts is usually determined based on subsequent usage requirements and building structural design.

[0068] For example, embedded parts refer to components made of metal or other materials that are placed in the structure before concrete is poured. They can be of various shapes and forms, such as reinforcing bars, steel plates, pipes, bolts, etc.

[0069] Optionally, embedded parts can be connected to external structures or equipment, supporting or fixing them: serving as anchor points for supporting or fixing temporary structures such as formwork and scaffolding.

[0070] The use of embedded parts can simplify subsequent installation work, improve project efficiency, and ensure the stability and safety of the structure.

[0071] For example, the embedded part includes at least one of the following: embedded plate, embedded steel bar, and shear key.

[0072] Alternatively, the embedded part can be an embedded plate. Due to its planar characteristics, embedded plates are often used in applications requiring large-area contact or connection. Embedded plates can serve as the foundation for subsequent connections to steel structures, concrete structures, or other structural components. For example, steel columns can be connected to embedded plates via welds, acting as a medium for load transfer within the structure, transferring loads from one component to another or the foundation. Furthermore, they provide precise positioning and fixing points for other structural components or equipment.

[0073] Alternatively, the embedded parts can also be embedded steel bars, which are mainly used to enhance the connection strength and stability of the structure, especially in concrete structures.

[0074] Alternatively, the embedded part can also be a shear key. Shear keys are usually placed in concrete to resist shear forces in the structure and ensure stable connections between structural components.

[0075] The combined effect of the embedded plate and the embedded steel bar significantly enhances the stability and load-bearing capacity of the structure. This reinforcement strategy is particularly crucial in applications such as the fixed hinge support 203, which must withstand vertical forces while meeting the requirements of omnidirectional rotation. Similarly, the friction pendulum support 204 is designed not only to cope with the effects of vertical forces but also to adapt to changes in omnidirectional displacement.

[0076] For example, the fixed hinge support 203 has vertical bearing capacity and allows for omnidirectional rotation. It allows the structure to rotate to a certain extent in the X and Y directions during an earthquake, but restricts the degree of freedom of rotation, thereby controlling the offset of the structure and ensuring structural stability. The fixed hinge support 203 is a support device used in building structures or mechanical engineering. Its main feature is that it allows the structure to rotate about a central point at the support, but does not allow the structure to produce any displacement in the horizontal and vertical directions. This means that the structure can rotate at the support to accommodate small angles of tilt or torsion, but cannot move in the X and Y directions (i.e., two orthogonal directions in the horizontal plane), and also has no degree of freedom of displacement in the Z direction (vertical direction).

[0077] Fixed hinge supports 203 play a crucial role in structural engineering. They efficiently transfer vertical loads such as the structure's self-weight and live loads, as well as axial forces caused by earthquakes, to the foundation or supporting structure, ensuring these forces are effectively absorbed and dispersed by the structural system. Simultaneously, they allow the structure to rotate at a limited angle at the support, a function essential for the structure to adapt to temperature changes, minor deformations, or slight uneven foundation settlement. Through this adaptability, fixed hinge supports 203 can mitigate rotational displacements caused by these factors, maintaining the geometric stability of the structure.

[0078] Furthermore, the fixed hinge support 203 plays a crucial role in limiting the horizontal and vertical displacement of the structure. This constraint helps control the deformation of the structure under external loads, preventing excessive displacement and thus ensuring the safety and stability of the structure. Especially in earthquake-prone areas, the design of the fixed hinge support 203 allows the structure to adapt to vibrations during earthquakes by rotating at the support, reducing the direct impact of seismic forces on the structure and significantly improving its seismic performance.

[0079] In conclusion, the fixed hinge support 203, with its advantages in load transfer, adaptability, structural stability, seismic performance, cost, and maintenance, has become an indispensable component in structural engineering design, providing solid foundation support for modern buildings and infrastructure.

[0080] To ensure structural stability in different directions and adapt to various environmental factors, the fixed hinge support 203 is often used in conjunction with the friction pendulum support 204.

[0081] The friction pendulum bearing 204 is a seismic isolation device inspired by the concept of a simple pendulum in physics. This bearing dissipates seismic energy through the friction of its spherical sliding surface, while simultaneously extending the structure's vibration period to reduce the impact of seismic forces. The friction pendulum bearing 204 can withstand vertical forces and also provides a certain degree of horizontal displacement to accommodate earthquake-induced displacement.

[0082] For example, the friction pendulum support 204 may be spherical.

[0083] In this application example, the friction pendulum support 204 is used in conjunction with the fixed hinge support 203 to jointly support the annular closed beam 202. By dissipating seismic energy and extending the natural vibration period, the friction pendulum support 204 reduces the seismic force transmitted to the skylight and the annular beam, protecting the structure from serious damage. In the event of an earthquake, the support 200 can release seismic energy, ensuring that the individual buildings do not collide, thereby also ensuring the safety of the cross-joint closed beam.

[0084] For example, Figure 3 This is a schematic diagram of a steel frame structure. The relative positions of the various components are shown in the diagram. In particular, the support 200 included in the diagram includes at least one fixed hinge support 203 or at least one friction pendulum support 204, which are respectively connected to the annular closed beam.

[0085] The combination of frame column 307, first embedded part 306, support 200, ring beam 303, second embedded part 308, steel column 302 and steel beam 301 forms a complete steel frame structure, which not only enhances the wind and earthquake resistance of the skylight, but also ensures the aesthetics and transparency of the structure.

[0086] Depend on Figure 3 It is easy to see that the frame column 307 is located at the bottom. Optionally, a support 200 is provided on the frame column 307. This support can be a friction pendulum support or a fixed hinge support. The frame column 307 and the support 200 are connected by a first embedded part 306. That is, the fixed hinge support 203 and the friction pendulum support 204 are respectively fixed to the frame column 307 by the first embedded part 306. The annular closed beam is supported by the support 200 and connected to the steel column by a second embedded part 308. The steel column and the steel beam are connected by bolts, together forming the above-mentioned steel frame structure.

[0087] For example, the annular closed beam 202 is connected to the frame column 307 on the side away from the frame column 307. (Combined) Figure 3 It can be seen that the frame column 307 and the annular closed beam 202 are supported by the support 200 and connected by a 24mm diameter steel strand 304 connected by the first embedded part 306. Figure 4 Enlarged view of the first embedded part of support 204 ， like Figure 4 As shown, the first embedded part consists of an embedded plate 3063, an embedded steel bar 3062, and a shear key.

[0088] One of the main functions of shear keys is to bear and resist shear forces, which is especially important at the connection between column bases and foundations. Their core function is to resist shear forces generated by the structure's own weight, live loads, wind loads, or seismic actions, forces that attempt to cause the structure to slide relative to each other along two parallel planes.

[0089] By fixing shear keys into the concrete, the displacement of structural members, such as column bases, relative to the foundation can be effectively limited, preventing slippage under shear forces and thus enhancing structural stability. Under extreme conditions such as earthquakes, shear keys are crucial for preventing relative sliding between structural members and are essential for improving the seismic performance of the structure.

[0090] In addition, since the fit clearance between traditional anchor bolts and bottom plate holes may not be sufficient to reliably resist shear forces, shear keys have emerged as a more effective shear resistance mechanism, providing flexibility for structural design and allowing engineers to comprehensively consider various load conditions in the design.

[0091] For example, when the first embedded part includes the shear key and the embedded plate, the shear key is located on the side of the annular closed beam 202 away from the frame column 307, and the shear key is pre-positioned below the embedded plate. The embedded steel bar 3062 and the shear key in the first embedded part 306 are pre-embedded before concrete pouring so that they can form an integral part with the concrete structure after the concrete hardens, thereby enhancing the connection strength and reliability.

[0092] In actual construction, shear keys are typically made of thick channel steel or steel plate, vertically welded to a horizontal steel plate at the bottom of the column base, and embedded in the concrete foundation. This construction method ensures that the shear keys can effectively bear shear forces and form an integral whole with the foundation, enhancing the overall stability and safety of the structure.

[0093] For example, the pull ring 3061 connected to the embedded steel bar in the first embedded part is made of Figure 4 As shown in the schematic diagram of the first embedded part, a prefabricated pull ring 3061 with a diameter of 75mm is respectively installed above the two embedded steel bars 3062 near the two sides. The larger diameter of this pull ring 3061 is designed to provide sufficient bearing area to withstand possible tensile or shear forces, while facilitating connection with other structural components.

[0094] For example, the finished pull ring 3061 and the embedded steel bar 3062 are mechanically connected, meaning they can be connected by threads, clips, or other mechanical means, rather than by welding. The advantages of mechanical connection are convenient installation, high reliability, and ease of on-site construction, while avoiding the heat-affected zone problems that may arise from welding.

[0095] For example, the support 200 can be divided into an upper support and a lower support. The upper support connects the support and the annular closed beam through a first embedded part, and the lower support connects the frame column 307 and the support through the first embedded part. Furthermore, the embedded reinforcing bars with pull rings near both sides of the support, i.e., the two outermost edges of the first embedded part, are connected by steel strands 304. The connection of the steel strands 304 increases the stability between the frame column, the support, and the annular closed beam, improving the load-bearing capacity and durability of the structure.

[0096] For example, Figure 5 This is a schematic diagram of the first embedded part installation hole structure of a cross-joint closed beam provided in this application embodiment. As can be seen from the figure, there are two types of installation holes in the schematic diagram. Installation holes 1-30631 are distributed at the four corners and are solid anchor bars with hooks. The white hole in the middle is installation hole 2-30632. Optionally, the specification can be 25mm.

[0097] The upper support plate of the aforementioned support is connected to the annular closed beam 202 via a first embedded part. The embedded reinforcing bars are also pre-cast within the annular closed beam 202. The frame column and the annular closed beam are connected via the aforementioned steel strands and the first embedded part, making the structure more stable.

[0098] For example, the annular closed ring beam 202 can be an annular concrete closed beam made of concrete.

[0099] In this embodiment, the innovative connection strategy of the annular closed beam 202 is not only reflected in its stable connection with the frame column 307, but also extended to its linkage with the steel column 302. This design method ensures that the closed beam can span multiple independent structural units, such as between different building units, to form a continuous and reinforced structural ring, thereby enhancing the overall stability and continuity of the structure.

[0100] For example, a second embedded part 308 is provided on the side of the annular closed beam 202 away from the frame column 307, and is connected to the steel column 302. Figure 6 This is a schematic diagram of the second embedded part, as shown below. Figure 6 As shown, combined with Figure 3 The embedded reinforcing steel bar 3062 is pre-cast into the annular closed beam 202, which is welded to the embedded plate as a whole and bolted to the steel column 302. The combined use of the embedded plate 3081 and the embedded reinforcing steel bar 3062 provides a robust connection point, allowing the steel structure to be securely connected to the concrete structure. The embedded plate 3063 provides a larger contact area, while the embedded reinforcing steel bar 3062 increases the anchorage depth and strength of the connection, enhancing its strength and reliability. Furthermore, pre-embedding the plate and reinforcing steel bar before concrete pouring simplifies the subsequent installation process. For example, when installing the steel structure, it can be directly welded or bolted to the embedded plate without on-site drilling or the use of expansion bolts, saving time and labor.

[0101] For example, a steel beam 301 is provided on the steel column 302, and the annular closed beam 202, the steel column 302 and the steel beam 301 are connected to form a steel frame structure. The steel column 302 is welded to the embedded part, and the steel column 302 and the steel beam 301 are bolted together.

[0102] In detail, the frame column 307 is installed on the annular closed beam 202, and the steel column 302 is connected to the annular closed beam 202.

[0103] For example, Figure 7 This is a schematic diagram of the steel column positioning for a translucent skylight roof with a cross-joint closed beam. Specifically, it shows the location of steel column 302, which is also the location of support 200. The support includes a friction pendulum support 204 and a fixed hinge support. (Combined with...) Figure 2 As can be seen from the installation diagram of the fixed hinge support 203 and the friction pendulum support 204, at least one support should be installed on the roof at each seismic joint 201. The positions of other supports need to be determined through professional calculations.

[0104] For example, Figure 8 A schematic diagram shows the installation holes for the steel column bases, including installation hole 3021. Besides bolt connections, steel columns and beams can also be connected by welding, but welding is inconvenient for on-site construction and the quality of the welds is difficult to guarantee; therefore, bolt connections are more common. These methods allow the steel structure to form a framework, thereby ensuring the safety and stability of the entire steel structure skylight. The overall effect is as follows. Figure 9 As shown, it satisfies the functional requirements of the building plan and the aesthetic effects of the building, thus improving the overall design level.

[0105] Overall, the meticulous design of the connection between the annular closed beam 202 and the frame column 307 and steel column 302, as well as the embedded part of the friction pendulum support 204, reflects the structural engineer's comprehensive consideration of structural stability, connection reliability, and construction convenience during the design process. This design not only enhances the structure's seismic performance and adaptability but also ensures efficiency and safety during construction, representing a significant manifestation of refinement and specialization in modern building structural design.

[0106] In summary, this application relates to building structures, and more particularly to a cross-joint closed beam structure. A cross-joint closed beam is installed on the roof of multiple individual buildings with seismic joints 201 between them. The roof is provided with frame columns 307. The cross-joint closed beam includes: supports mounted on the frame columns 307; and an annular closed beam 202 connected above the supports; wherein the annular closed beam 202 spans the seismic joints 201 of each of the individual buildings. This forms a new overall building function, improving the continuity and integrity of the building.
