Description

Technical Field

[0001] The invention relates to the technical field of large-span spatial structures of buildings, and in particular to a rigid roof, a building and a construction method of the rigid roof. Background Art

[0002] At present, in large-span buildings at home and abroad, annular tension cable-truss structures, spoke-type beam-string structures and some new cable-truss structures are widely used in the roof design of large-span buildings. In the design of cable-truss structures, the force analysis process is relatively complicated, and there is no general program that can fully analyze such structures. Designers need to have a high professional background and special skills to be able to design cable-truss structures. When constructing cable-truss structures, since the cables are flexible components and they must be tensioned during construction, the construction forming analysis is closely related to the actual tensioning process of the structure, which places high demands on the construction team and cannot achieve the popularity of cable-truss structures. In addition, in cable-truss structures, when they encounter strong or heavy winds, the structure deforms greatly and generates a lot of noise, which affects their service life.

DETAILED DESCRIPTION

[0058] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0059] In the present invention, the directions or positional relationships indicated by the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom", "inner", "outer", "middle", "vertical", "horizontal", "lateral", "longitudinal" and the like are based on the directions or positional relationships shown in the drawings. These terms are mainly used to better describe the present invention and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific direction, or to be constructed and operated in a specific direction.

[0060] In addition, some of the above terms may be used to express other meanings in addition to indicating orientation or positional relationship. For example, the term "on" may also be used to express a certain dependency or connection relationship in some cases. For those skilled in the art, the specific meanings of these terms in the present invention can be understood according to specific circumstances.

[0061] In addition, the terms "installed", "set", "provided with", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0062] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise specified, "plurality" means two or more.

[0063] As people's functional requirements for building venues become more diverse, the functional requirements for gymnasiums, performance halls, etc. are becoming more and more diverse. Take the gymnasium as an example. As a landmark building that symbolizes the sports and cultural spirit of a city, the gymnasium building must not only meet the needs of accommodating multiple sports events, but also accommodate tens of thousands of spectators to watch sports games. Therefore, while the gymnasium building is a landmark building, it must also be highly practical and compatible. In order to accommodate tens of thousands of spectators, gymnasium buildings usually occupy a large area and are mostly large-span structures. In addition, in order to meet the landmark building requirements of gymnasium buildings, their building appearance usually needs to be specially designed. In the past, gymnasium buildings mostly used rigid roof structure systems such as grids, grid shells, cantilever tube trusses, and arch supports to form unique structural shapes. At the same time, these traditional structural systems and construction methods are relatively mature and are also familiar to the majority of designers. That is, it has become a trend to design the roof of gymnasium buildings as steel structures.

[0064] With the emergence of cable dome structures and cable-membrane structures, gymnasiums mostly use flexible space cable-truss structures, which not only have a unique appearance design, but also the building roof with a large opening in the middle improves the lighting of the gymnasium building and the audience's field of vision.

[0065] However, compared with the ordinary structural system, the main difference between the annular tension cable truss structure is the source of the vertical stiffness of the structure. The vertical stiffness of the annular tension cable truss structure is basically contributed by prestress, that is, by tensioning the radial cable, the inner ring cable is tensioned and the outer ring beam is compressed to form a stable initial equilibrium state of the structure. Its stiffness can be obtained on demand by adjusting the size of the prestress. That is, the initial equilibrium state of the structure is achieved by applying prestress to flexible components such as cables after the building is completed. This increases the difficulty of force analysis of the overall structure during the design process of the annular tension cable truss structure. At the same time, since the flexible components are greatly affected by external loads, the overall building needs to be subjected to three stages during the design process: initial form, form, and load state. This includes not only traditional internal force calculations, but more importantly, the geometric and topological analysis of the system. This analysis method and analysis means are significantly different from traditional structural thinking habits, and there is no general program that can fully analyze such structures. It requires a high professional background and special skills to master and apply this technology. In addition, this annular tension cable truss structure needs to be installed according to the topological relationship during the construction process because the shape of the flexible components cannot be controlled, which greatly increases the difficulty of the construction personnel's work. In addition, the flexible structure is greatly affected by external loads, that is, it is easy to deform or generate excessive noise, which will affect the user experience.

[0066] For ordinary structural systems, such as lattice shells, grids or cantilever structures, their structural types are mainly full-covered roof structures, that is, there is no large opening in the middle of the building. In order to achieve the requirement of large opening in the middle, it is necessary to support the roof structural system or add external steel beams for cantilevering. However, since this type of building has high force requirements for cantilevered steel beams, the strength requirements for steel columns used to fix cantilevered steel beams are extremely high, and the service life is relatively low. Especially in the renovation of existing gymnasium buildings, the load-bearing system in the existing structure cannot bear the load of the cantilever structure, resulting in a greatly reduced service life of the gymnasium building.

[0067] Based on this, the present application discloses a rigid roof, which adopts a steel structure design, including a rigid pressure ring, a rigid pull ring and a plurality of radial connection components, by arranging the rigid pull ring on the outer periphery of the rigid pressure ring and spacing it with the rigid pressure ring, and at the same time, a plurality of radial connection components are arranged between the rigid pressure ring and the rigid pull ring and distributed radially along the center of the rigid pressure ring, and the two ends of each radial connection component are rigidly connected to the rigid pressure ring and the rigid pull ring respectively. In this way, the self-weight of the above-mentioned structures (such as the rigid pressure ring, the rigid pull ring, and the radial connection components) is used to form a structural self-balancing system, without the need to apply additional tension, which greatly improves the overall rigidity and strength of the structure to bear external loads.

[0068] The technical solution of the present invention will be further described below in conjunction with embodiments and drawings.

[0069] See also Figure 1 and Figure 2 In a first aspect, the present embodiment provides a rigid roof 100, which is applied to a building and arranged on the top of the building. The rigid roof 100 includes a rigid pressure ring 10, a rigid pull ring 20 and a plurality of radial connection components 30; the rigid pull ring 20 is used to be connected to the top of the building, and the rigid pull ring 20 is arranged on the outer periphery of the rigid pressure ring 10 and is spaced apart from the rigid pressure ring 10; a plurality of radial connection components 30 are arranged between the rigid pressure ring 10 and the rigid pull ring 20, and the plurality of radial connection components 30 are radially distributed along the center of the rigid pressure ring 10, and each radial connection component 30 includes a first end 31 and a second end 32 opposite to each other, the first end 31 of the radial connection component 30 is rigidly connected to the rigid pressure ring 10, and the second end 32 of the radial connection component 30 is rigidly connected to the rigid pull ring 20.

[0070] It can be understood that the rigid roof 100 is an inner and outer ring structure, the rigid pressure ring 10 serves as the inner ring of the rigid roof 100, and when the rigid roof 100 is built, its inner ring is subjected to pressure to form the rigid pressure ring 10, and the rigid pull ring 20 serves as the outer ring of the rigid roof 100, and when the rigid roof 100 is built, its outer ring is subjected to tension to form the rigid pull ring 20.

[0071] That is, each structure in the rigid roof 100 is rigidly connected to form a structural whole. It can be seen that the rigid pressure ring 10, the rigid pull ring 20 and the plurality of radial connection components 30 are rigidly connected to form a complete rigid roof 100. In actual construction, the rigid pull ring 20 can be first rigidly connected to the top of the building to form a connection foundation for the rigid roof 100; then a temporary bracket is built, and the temporary bracket is used to support the radial connection component 30 during the construction of the rigid roof 100; the second end 32 of the radial connection component 30 is rigidly connected to the rigid pull ring 20, and a part of the radial connection component 30 is overlapped on the temporary bracket, and the radial connection component 30 is supported by the temporary bracket, so that the radial connection component 30 can be connected to the rigid pull ring 20 at the second end 32 of the radial connection component 30. After the pull ring 20, the first end 31 of the radial connection assembly 30 can be suspended on the side of the temporary bracket away from the rigid pull ring 20, that is, the first end 31 of the radial connection assembly 30 is suspended in the air to reach the height at which the rigid pressure ring 10 needs to be installed; after the second ends 32 of all the radial connection assemblies 30 are rigidly connected to the rigid pull ring 20 and overlapped on the temporary bracket, the first end 31 of the radial connection assembly 30 can form an installation space for the rigid pressure ring 10; finally, the rigid pressure ring 10 is rigidly connected to the first end 31 of the radial connection assembly 30, and the temporary bracket is removed.

[0072] Since temporary brackets are used to support the radial connection assembly 30 during the construction of the rigid roof 100, the temporary brackets bear the gravity from the radial connection assembly 30, and when the rigid pressure ring 10 is connected to the radial connection assembly 30, the temporary bracket also bears part of the gravity from the rigid pressure ring 10; when the temporary bracket is removed, the gravity of the rigid pressure ring 10 and the radial connection assembly 30 is released, and the rigid pressure ring 10 and the radial connection assembly 30 will have a certain horizontal and vertical displacement. Through the analysis and calculation of the force and deformation of the rigid roof 100 during the design process, and with the help of the constraints of the rigid connection structure of each component of the rigid roof 100, this displacement can be controlled within a controllable range. In addition, in the rigid roof 100, the rigid pressure ring 10, the rigid pull ring 20 and the radial connection assembly 30 connected by the rigid connection provide a complete path for the force transmission of the entire rigid roof 100.

[0073] It can be seen that the rigid roof 100 of the present application forms a structural self-balancing system by leveraging the self-weight of the above-mentioned structures (such as the rigid pressure ring 10, the rigid pull ring 20, and the radial connection assembly 30), without the need for additional tension, thereby greatly improving the overall stiffness and strength of the structure to bear external loads.

[0074] In order to facilitate understanding of the structural self-balancing system formed by the rigid roof 100, the stress conditions of the rigid roof 100 will be described in detail below with reference to the accompanying drawings.

[0075] Specifically, under the action of its own weight, the internal force transmission is as follows: Figure 1 As shown by the arrow in the middle, Figure 1 In the embodiment, since the middle of the rigid roof 100 is a hollow structure, the radial connection assembly 30 cannot transmit the internal force through direct connection. At this time, since the rigid pressure ring 10 rigidly connects the radial connection assembly 30 to the rigid pressure ring 10, the rigid pressure ring 10 will be subjected to the pressure F generated by the influence of the gravity of all radial connection assemblies 30. 1 , and due to the rigid connection between the rigid pressure ring 10 and the radial connection assembly 30, the radial connection assembly 30 can separate the rigid pressure ring 10 and its own gravity F 2 The rigid pull ring 20 is transmitted to the rigid pull ring 20, so that the rigid pull ring 20 is subjected to the tensile force F 3, so that the rigid roof 100 forms a force-bearing structure of tension and compression rings, forms a load-bearing structure of the radial connection assembly 30 through the rigid compression ring 10, and forms a gravity-bearing structure of the rigid compression ring 10 and the radial connection assembly 30 through the rigid pull ring 20, and then converts the respective gravity into the structural internal force of the rigid roof 100 to form a gravity self-balancing system. After the rigid roof 100 forms a self-balancing system under the action of its own weight, the rigid roof 100 can improve the rigidity and strength of the rigid roof 100 under the influence of its internal force, making the rigid roof 100 more stable, and at the same time, the spanning capacity of the rigid roof 100 can be increased, which can be adapted to large-span space structures.

[0076] Furthermore, when the rigid roof 100 is subjected to external load, a force analysis is performed by intercepting a group of radial connection components 30 of the rigid roof 100 and the connection points of the rigid pressure ring 10 and the rigid pull ring 20. The force analysis diagram is shown in FIG. Figure 3 As shown, after the temporary support is removed, the rigid pressure ring 10 will produce horizontal and vertical displacements. Therefore, according to the force characteristics of the connection point between the radial connection component 30 and the rigid pressure ring 10, this connection point can be simplified into an elastic support force model. At the same time, when the rigid roof 100 is connected to the top of the building with a movable hinge support, since the movable hinge support can be offset in the horizontal direction but is fixed in the vertical direction, according to the force characteristics of the connection point between the rigid pull ring 20 of the rigid roof 100 and the top of the building, the connection point can be simplified into an elastic support model in the horizontal direction and a fixed support model in the vertical direction.

[0077] Specifically, when the rigid roof 100 is subjected to Figure 3 When the external load q is shown, without considering the self-weight of the rigid roof 100, it is assumed that the rigid connection point between the rigid pull ring 20 and the radial connection assembly 30 is the connection point A, the rigid connection point between the rigid pressure ring 10 and the radial connection assembly 30 is the connection point C, the horizontal distance between the connection point A and the connection point C is x, and the vertical distance between the connection point C and the connection point A is y. Under the action of the external load q, the connection point A will be subjected to a vertical force R from the movable hinge support. 1 At the same time, the connection point A will be subjected to the horizontal force R provided by the movable hinge support. 2 , the connection point C is subject to the horizontal R 3 The force of

[0078] When the external load is q, we know that R 1 =qx,

[0079] According to the equilibrium equation: ∑F x =0,M A =0;

[0080] We can get:

[0081] Among them, ∑F x is the sum of the external forces in the x direction borne by the rigid roof 100 structure;

[0082] M A is the sum of the moments borne by the rigid roof 100 structure at point A;

[0083] That is, when the top of the building has a movable hinge support, and when the thrust in the horizontal and vertical directions that the movable hinge support can withstand satisfies the above relationship, the rigid roof 100 can achieve structural stability under the action of external loads, that is, form a structural self-balancing system.

[0084] It can be understood that the above-mentioned external loads may include wind loads, snow loads and other forces from the external environment.

[0085] It can be seen from the above force analysis process that when the roof structure adopts a purely rigid structure, the force analysis process of the rigid roof 100 formed can be simpler and clearer, which can effectively simplify the design work of the roof structure, reduce the difficulty of force analysis of the rigid roof 100, and realize the design popularity of the rigid roof 100.

[0086] Since the vertical stiffness of the building roof has a great influence on the self-stability of the roof structure, compared with the annular tension cable truss structure with a large opening in the middle, the rigid roof 100 uses all-rigid materials (i.e., steel structure) and all-rigid connections to replace the flexible components in the annular tension cable truss structure, and the vertical stiffness of the pure rigid structure comes from the component material itself, that is, its own stiffness can keep it in a stable initial form (such as beams, columns and other components, which is a geometrically stable system), that is, in the above-mentioned force analysis, the rigid roof 100 can form a self-balancing system to form a stable structure. At the same time, the change in the shape of the rigid structure due to the external load is small, and the rigid roof 100 can achieve small deformation under the external load to ensure the stability of the overall structure.

[0087] Compared with the existing grid shell or cantilever structure, the rigid roof 100 can form a stable structure through the rigid connection between the rigid pressure ring 10, the rigid pull ring 20 and the radial connection assembly 30, and no longer needs an external supporting structure or cantilever structure to support the entire roof with external force to achieve the stability of the roof structure with a large opening in the middle. Since there is no need to add an external cantilever structure to reinforce the roof, the rigid roof 100 will not affect the bearing capacity of the building, and can also ensure the service life of the building.

[0088] In order to form a self-balancing system of the rigid roof 100, a large amount of calculation and analysis is used to determine that in order to achieve the stability of the structural system of the rigid roof 100, in addition to limiting the materials and connections of the rigid roof 100, it is also necessary to design the sagittal height of the rigid roof 100, the rigid pressure ring 10, the rigid pull ring 20 and the cross-sectional form of the radial connection assembly 30. At the same time, in order to reduce the bearing capacity requirements of the rigid roof 100 on the building, an optimized design method is also given for the connection method between the rigid roof 100 and the top of the building.

[0089] Firstly, in order to better control the stability of the rigid roof 100 , during the design process, the deformation of the rigid roof 100 can be controlled by adjusting the sagittal height of the rigid roof 100 .

[0090] Specifically, see Figure 4 In the rigid roof 100, the relative height difference between the top of the rigid pressure ring 10 and the center of the rigid pull ring 20 in the vertical direction is the rise H of the rigid roof 100; the horizontal distance between the two connection points of the radial connection assembly 30 and the rigid pressure ring 10 and the rigid pull ring 20 is the span B of the rigid roof 100; then the rise-span ratio of the rigid roof 100 is H / B.

[0091] In order to ensure that the deformation of the rigid roof 100 is small after the temporary support is removed, and at the same time, the support requirements for the top of the building are low to achieve the stability of the rigid roof 100, the relationship between the rise and the building span can be restricted during the design process. For example, the ratio of the rise to the building span can be gradually increased to perform analysis to obtain a stable rigid roof 100.

[0092] When the rigid roof 100 needs to adapt to buildings with different spans, the rise of the rigid roof 100 can be adjusted to obtain a suitable rise-to-span ratio to adjust the structural internal force, so that the rigid roof 100 can adapt to buildings with different spans.

[0093] Furthermore, considering that in different building scenarios, the required shapes of the rigid roof 100 are different, the radial connection assembly 30 can be Figure 4 As shown, the radial connection assembly 30 can be connected between the rigid pressure ring 10 and the rigid pull ring 20 in a straight line, or the radial connection assembly 30 can be Figure 5 As shown, the radial connection assembly 30 can also be connected in a curved shape when connected between the rigid pressure ring 10 and the rigid pull ring 20 .

[0094] like Figure 4 As shown, when the radial connection assembly 30 is connected in a straight line, the rise-span ratio of the rigid roof 100 is When the rigid roof 100 is calculated and analyzed, the following can be obtained: Figure 6 As shown in the curve, it can be seen from the figure that when the radial connection assembly 30 is connected in a straight line, no matter whether the rigid roof 100 is affected by its own gravity or by external loads, the larger the rise-to-span ratio of the rigid roof 100 is, the smaller the structural deformation of the rigid roof 100 is, and the better the structural stiffness is. Therefore, in the design process of the rigid roof 100, a suitable rise-to-span ratio can be selected to ensure the structural stability of the rigid roof 100.

[0095] like Figure 5 As shown, when the radial connection assembly 30 is connected in a curved shape, the rise-span ratio of the rigid roof 100 is When the rigid roof 100 is calculated and analyzed, the following can be obtained: Figure 7 As shown in the curve, it can be seen from the figure that when the radial connection assembly 30 is connected in a curved shape, no matter whether the rigid roof 100 is affected by its own gravity or by an external load, the larger the rise-to-span ratio of the rigid roof 100 is, the smaller the structural deformation of the rigid roof 100 is, and the better the structural stiffness is. Therefore, in the design process of the rigid roof 100, a suitable rise-to-span ratio can be selected to ensure the structural stability of the rigid roof 100.

[0096] In addition, by comparing Figure 6 and Figure 7 It can be seen from the curve in that, under the influence of the same force, the vertical displacement of the rigid pressure ring 10 of the rigid roof 100 of the radial connection assembly 30 connected in a straight line is smaller, and the vertical displacement of the rigid pressure ring 10 of the rigid roof 100 of the radial connection assembly 30 connected in a curved line is greater than the vertical displacement of the rigid roof 100 of the radial connection assembly 30 connected in a straight line, that is, the rigid roof 100 of the radial connection assembly 30 connected in a straight line has a better rigidity than the rigid roof 100 of the radial connection assembly 30 connected in a curved line, that is, when the radial connection assembly 30 is connected in a straight line, the rigid roof 100 has better rigidity and smaller structural deformation of the rigid roof 100. Therefore, when the building has no specific requirements on the shape of the rigid roof 100, the radial connection assembly 30 connected in a straight line can be preferred, and the design difficulty of the rigid roof 100 can also be reduced.

[0097] It can be understood that the rigid pressure ring 10 and the rigid pull ring 20 of the rigid roof 100 can be designed to be circular, elliptical, or approximately circular or elliptical ring structures. At the same time, the rigid pressure ring 10 and the rigid pull ring 20 can be arranged concentrically or eccentrically. Their specific shape and arrangement can be selected based on the specific design and force analysis, and are not specifically limited in this embodiment.

[0098] Specifically, the rigid pressure ring 10 can be formed by welding a plurality of rigid sub-rods. Similarly, the rigid pull ring 20 and the radial connection assembly 30 can also be formed by welding a plurality of rigid sub-rods. The rigid pressure ring 10, the rigid pull ring 20 and the radial connection assembly 30 are then rigidly connected to form the rigid roof 100.

[0099] Furthermore, the structure of the rigid compression ring 10 may be at least one of a solid steel beam, a plane truss or a three-dimensional truss.

[0100] In one example, when the rigid roof 100 is located in an environment where environmental loads such as wind loads have little effect on the rigid roof 100, for example, when the rigid roof 100 is located at a low altitude, the wind load in the environment is small or relatively regular, and strong winds, severe rain and snow are not likely to occur in the environment, or when the span of the building is appropriate, solid steel beams can be preferentially used to form the rigid compression ring 10 to ensure that the structural stability of the rigid roof 100 is sufficient, which can simplify the force analysis in the design process and the construction process.

[0101] In another example, when the load influence from the environment in which the rigid roof 100 is located is too large, for example, the rigid roof 100 is located at a high altitude, the wind load in the environment is large, and strong winds, severe rain and snow weather are prone to occur in the environment, or when the span of the building is too large, and the deformation of the rigid roof 100 cannot be controlled within an ideal range by adjusting the span-rise ratio of the rigid roof 100, it can be considered to replace the solid steel beam with a plane truss structure to improve the force transmission effect and force stability of the rigid pressure ring 10.

[0102] In another example, when the external load from the environment in which the rigid roof 100 is located is relatively complex, for example, the rigid roof 100 is located at a high altitude, the wind load in the environment is large and the direction of the wind load is unstable, and severe rain and snow weather and large temperature differences are prone to occur in the environment, a three-dimensional truss can be used to form a rigid compression ring 10. Since the three-dimensional truss is a spatial structure, it can better withstand forces from all directions, so that the rigid compression ring 10 can better withstand and transmit the external load from the environment, so that the external load borne by the rigid compression ring 10 can be transmitted to the radial connection assembly 30 through multiple force transmission paths, and then transmitted to the rigid pull ring 20 and the building system, so as to better share the pressure of the rigid compression ring 10, so that the external load force borne by the rigid roof 100 can be better released, so as to achieve the structural stability of the rigid roof 100 structure under the action of complex external loads.

[0103] Similarly, the structure of the rigid pull ring 20 can also be a solid steel beam, a plane truss or a three-dimensional truss. When the rigid roof 100 is located in an environment where environmental loads such as wind loads have little effect on the rigid roof 100, for example, when the rigid roof 100 is located at a low altitude, the wind load in the environment is small or relatively regular, and it is not easy to have strong winds, severe rain and snow weather, etc. in the environment, or when the span of the building is appropriate, solid steel beams can be preferably used to form the rigid pull ring 20 to ensure that the structural stability of the rigid roof 100 is sufficient, and the force analysis and construction process in the design process can be simplified.

[0104] When the load influence from the environment in which the rigid roof 100 is located is too large, for example, when the rigid roof 100 is located at a high altitude and the wind load in the environment is large, and strong winds, severe rain and snow weather are prone to occur in the environment, or when the span of the building is too large, and the deformation of the rigid roof 100 cannot be controlled within an ideal range by adjusting the rise-span ratio of the rigid roof 100, it can be considered to replace the solid steel beam with a plane truss structure to improve the force transmission effect and force stability of the rigid pull ring 20.

[0105] When the external load from the environment in which the rigid roof 100 is located is relatively complex, for example, when the rigid roof 100 is located at a high altitude, the wind load in the environment is large and the direction of the wind load is unstable, and severe rain and snow weather and large temperature differences are prone to occur in the environment, a three-dimensional truss can be used to form the rigid pull ring 20. Since the three-dimensional truss is a spatial structure, it can better withstand forces from all directions, so that the rigid pull ring 20 can better withstand and absorb the external load in the environment on the rigid pressure ring 10 and the radial connection assembly 30. The external load force borne by the rigid pull ring 20 and the radial connection assembly 30 can be transmitted to the building body through multiple force transmission paths, so as to better share the pressure of the rigid pressure ring 10, thereby better releasing the external load force borne by the rigid roof 100, so as to achieve the structural stability of the rigid roof 100 structure under the action of complex external loads.

[0106] In addition, the radial connection assembly 30 can be a solid steel beam, a box steel beam, a plane truss, and a three-dimensional truss structure. Since the radial connection assembly 30 mainly plays the role of transmitting the self-weight of the rigid roof 100 in the rigid roof 100, when the rigid roof 100 adopts the above-mentioned structural form, the effect of effectively transmitting the self-weight can be achieved. The selection of the structural form of the radial connection assembly 30 can refer to the selection principle of the above-mentioned rigid pressure ring 10 and rigid pull ring 20. At the same time, when the structure of the rigid pressure ring 10 and the rigid pull ring 20 is relatively complex, that is, when the structural rods of the rigid pressure ring 10 and the rigid pull ring 20 are relatively more, the self-weight of the rigid roof 100 will increase. At this time, the structural form of the radial connection assembly 30 can be selected as a plane truss structure or a three-dimensional truss structure to ensure that the radial connection assembly 30 can effectively transmit the self-weight of the rigid roof 100 and achieve the structural stability of the rigid roof 100.

[0107] As can be seen from the foregoing, when designing the rigid roof 100, the structural forms of the rigid pressure ring 10, the rigid pull ring 20, and the radial connection assembly 30 can be selected as needed. At the same time, when the structure of the rigid pressure ring 10 is a solid steel beam, the rigid pull ring 20 can be a solid steel beam, a plane truss or a three-dimensional truss, and the structural form of the radial connection assembly 30 can be a solid steel beam, a box-type steel beam, a plane truss or a three-dimensional truss; when the rigid pressure ring 10 is a plane truss structure, the rigid pull ring 20 can be a solid steel beam, a plane truss or a three-dimensional truss, and the structural form of the radial connection assembly 30 can be a solid steel beam, a box-type steel beam, a plane truss or a three-dimensional truss; similarly, when the rigid pressure ring 10 is a three-dimensional truss structure, the rigid pull ring 20 can be a solid steel beam, a plane truss or a three-dimensional truss, and the structural form of the radial connection assembly 30 can be a solid steel beam, a box-type steel beam, a plane truss or a three-dimensional truss. That is, the rigid pressure ring 10, the rigid pull ring 20 and the radial connection assembly 30 can be selected and matched after a force analysis based on the environmental characteristics and architectural form of the rigid roof 100. In this embodiment, the rigid pressure ring 10, the rigid pull ring 20 and the radial connection assembly 30 are not limited.

[0108] For some examples, see Figure 8In order to improve the stress stability of the rigid roof 100, the rigid roof 100 may further include at least one annular component 40, which is arranged between the rigid pressure ring 10 and the rigid pull ring 20, and is connected to the radial connection component 30. When the annular component 40 is one circle, the annular component 40 may be arranged in the middle of the rigid pressure ring 10 and the rigid pull ring 20, and is rigidly connected to the radial connection component 30, so as to support the radial connection component 30, effectively prevent the radial connection component 30 from being deformed, and at the same time, prevent the rigid pressure ring 10 and the rigid pull ring 20 from failing, thereby improving the overall structural rigidity of the rigid roof 100. It is understood that the annular component 40 and the radial connection component 30 may be rigidly connected or hinged, and the specific connection method may be selected after the actual stress analysis to ensure the structural rigidity and strength of the rigid roof 100. In this embodiment, there is no specific restriction on the connection between the annular component 40 and the radial connection component 30.

[0109] See also Fig. 9 , Fig.10 When the environmental load of the rigid roof 100 is relatively complex, for example, the rigid roof 100 is located at a high altitude, the wind load in the environment is large and the direction of the wind load is unstable, and severe rain and snow weather and large temperature differences are likely to occur in the environment, it is possible to consider setting up multiple ring components 40. At this time, the multiple ring components 40 can be evenly spaced between the rigid pressure ring 10 and the rigid pull ring 20, and connected to the radial connection component 30 to ensure that the support effect of the ring component 40 on the radial connection component 30 is more uniform, that is, the effect of the radial component transferring gravity can be better shared. In addition, when designing the rigid roof 100, when comprehensively considering the environmental factors and the influencing factors of the building span, the structure of the ring component 40 can be selected as a plane truss or a three-dimensional truss structure to improve the stability of the rigid roof 100 structure.

[0110] It is understandable that when the annular component 40 is disposed between the rigid pressure ring 10 and the rigid pull ring 20 , the annular component 40 can be disposed concentrically with the rigid pressure ring 10 and the rigid pull ring 20 , and of course, can also be disposed eccentrically with the rigid pressure ring 10 and the rigid pull ring 20 .

[0111] For example, Fig. 9 , Fig.10 As shown, in Fig. 9In the rigid roof 100 shown in FIG. 1 , the structures of the rigid compression ring 10 and the rigid pull ring 20 are both solid steel beams, the structure of the radial connection assembly 30 is a three-dimensional truss, and the structure of the annular assembly 40 is a plane truss. When the span of the rigid roof 100 is large, the required size of the rigid roof 100 is large, and the structural deadweight of the rigid roof 100 becomes large. In order to better transmit the self-gravity of the rigid roof 100, ensure the stability of the internal force of the rigid roof 100, and achieve the stability of the overall structure of the rigid roof 100, the structure of the radial connection assembly 30 can be selected as a three-dimensional truss structure. At the same time, in order to effectively prevent the structural instability of the radial connection assembly 30, it can be supported by setting a plurality of circles of annular assemblies 40, and the structure of the annular assembly 40 can be selected as a plane truss structure to better help the radial connection assembly 30 to transmit the internal force, so as to achieve the structural self-balancing system of the rigid roof 100. In addition, the three-dimensional truss structure of the radial connection assembly 30 and the planar truss structure of the annular assembly 40 can help the rigid roof 100 to better resist the effect of external loads to ensure the stability of the structure.

[0112] It can be understood that in the three-dimensional truss structure of the radial connection component 30 and the plane truss structure of the annular component 40, the structural shapes of the three-dimensional truss and the plane truss and the arrangement and connection positions of the upper chord, lower chord, diagonal web and vertical rods in the truss structure can be designed and arranged through force analysis, and are not specifically limited in this embodiment, but all of its rods are rigid rods, and the connections between the rigid rods are rigid connections to ensure the rigidity of the structure.

[0113] For example, Fig.11 , Fig.12 As shown, in Fig.11 In the structure of the rigid roof 100 shown in FIG, the rigid compression ring 10 and the rigid pull ring 20 are both solid steel beams, the structure of the radial connection assembly 30 is a three-dimensional truss, and the structure of the annular assembly 40 is a three-dimensional truss. When the span of the rigid roof 100 is large, the required size of the rigid roof 100 is large. At this time, the structural deadweight of the rigid roof 100 becomes large. In order to better transmit the self-gravity of the rigid roof 100, ensure the stability of the internal force of the rigid roof 100, and achieve the stability of the overall structure of the rigid roof 100, the structure of the radial connection assembly 30 can be selected as a three-dimensional truss structure. At the same time, in order to effectively prevent the structural instability of the radial connection assembly 30, it can be supported by setting a plurality of circles of annular assemblies 40, and the structure of the annular assembly 40 can be selected as a three-dimensional truss structure to better help the radial connection assembly 30 to transmit the internal force, so as to achieve the self-balancing system of the rigid roof 100. In addition, the three-dimensional truss structure of the radial connection assembly 30 and the three-dimensional truss structure of the annular assembly 40 can help the rigid roof 100 to better resist the effect of external loads to ensure the stability of the structure.

[0114] It can be understood that in the three-dimensional truss structure of the radial connection component 30 and the three-dimensional truss structure of the annular component 40, the shape of the three-dimensional truss and the arrangement and connection positions of the upper chord, lower chord, diagonal web and vertical rods in the truss structure can be designed and arranged through force analysis, and are not specifically limited in this embodiment, but all of its rods are rigid rods, and the connections between the rigid rods are rigid connections to ensure the rigidity of the structure.

[0115] For some examples, see Figures 13 to 15 In order to improve the structural rigidity of the rigid roof 100 and the effect of transmitting the horizontal load, the rigid roof 100 also includes an annular support assembly 50 located between the rigid pressure ring 10 and the rigid pull ring 20, and the annular support assembly 50 is rigidly connected to the rigid pull ring 20 and the annular assembly 40 adjacent to the rigid pull ring 20.

[0116] As can be seen from the above, the annular component 40 can be one or more. When the annular component 40 is more than one, taking the multiple annular components 40 and the rigid pressure ring 10 and the rigid pull ring 20 as an example, among the multiple annular components 40, the annular component 40 adjacent to the rigid pull ring 20 is defined as the first annular component 41, and a first support space can be formed between the rigid pull ring 20 and the first annular component 41 adjacent thereto, and the first support space is the annular space formed between the rigid pull ring 20 and the first annular component 41. Since the rigid pull ring 20 and the first annular component 41 are connected to the radial connection component 30, and there are multiple radial connection components 30 between the rigid pressure ring 10 and the rigid pull ring 20, the radial connection component 30 can divide the first support space into multiple first support units 61, and an annular support component 50 is provided in each first support unit 61. There are multiple first support units 61, that is, the annular support assembly 50 can be arranged in multiple first support units 61. The multiple annular support assemblies 50 can equally divide the internal force from the rigid pull ring 20, the first annular assembly 41 and the adjacent radial connection assembly 30, so that the internal force borne by each group of annular support assemblies 50 is reduced, thereby improving the structural stability of the annular support assemblies 50.

[0117] Specifically, see Fig.16, the annular support assembly 50 includes a first oblique rod 51 and a second oblique rod 52, the first oblique rod 51 and the second oblique rod 52 are cross-connected in the first support unit 61, and both ends of the first oblique rod 51 and the second oblique rod 52 are rigidly connected to each first support unit 61. Exemplarily, taking the first support unit 61 as an approximately fan-shaped annular unit as an example, the fan-shaped annular unit includes four nodes, namely a first node 611, a second node 612, a third node 613, and a fourth node 614, wherein the first node 611 is formed by connecting one of two adjacent radial connection assemblies 30 and the first annular assembly 41, the second node 612 is formed by connecting the other of the two adjacent radial connection assemblies 30 and the first annular assembly 41, the third node 613 is formed by connecting one of the two adjacent radial connection assemblies 30 and the rigid pull ring 20, and the fourth node 614 is formed by connecting the other of the two adjacent radial connection assemblies 30 and the rigid pull ring 20. Two ends of the first oblique rod 51 are connected to the first node 611 and the fourth node 614 respectively, and two ends of the second oblique rod 52 are connected to the second node 612 and the third node 613 respectively.

[0118] The annular support assembly 50 is arranged in the first support unit 61 through the intersection of the first oblique rod 51 and the second oblique rod 52, which can improve the structural stability of the first support unit 61. At the same time, the annular support assembly 50 can better withstand the load from the horizontal direction, and can effectively prevent the radial connection assembly 30 from being deformed under the action of the horizontal load, that is, the first oblique rod 51 and the second oblique rod 52 can push and pull the two adjacent radial connection assemblies 30. When the horizontal load causes the two adjacent radial connection assemblies 30 to generate forces in opposite directions. Without the support of the first oblique rod 51 and the second oblique rod 52, the two adjacent radial connection assemblies 30 will be deformed by approaching each other, and the distance between the two adjacent radial connection assemblies 30 will be reduced, while the distance from other radial connection assemblies 30 will be increased. When the first diagonal rod 51 and the second diagonal rod 52 are arranged between two adjacent radial connection components 30, the first diagonal rod 51 and the second diagonal rod 52 can generate a force to resist the deformation of the radial connection component 30. When each first support unit 61 is provided with an annular support component 50, the first diagonal rod 51 and the second diagonal rod 52 between two adjacent first support units 61 can achieve the continuity of the force transmission path through the radial connection component 30, that is, the external horizontal load can be transmitted to other first support units 61 connected thereto, so as to weaken the influence of the horizontal load on a certain first support unit 61, and weaken the local force by the overall structure, so as to prevent the local force from being too large and causing local deformation, thereby affecting the stability of the entire structure.

[0119] At the same time, since the first diagonal rod 51 and the second diagonal rod 52 are connected to the above-mentioned nodes of the radial connection component 30 and the rigid pull ring 20 and the first annular component 41, the first diagonal rod 51 and the second diagonal rod 52 can also support the rigid pull ring 20 and the first annular component 41 adjacent thereto. The supporting effect and supporting function generated can be referred to the above-mentioned analysis of the adjacent radial connection component 30, which will not be repeated here.

[0120] In some embodiments, in order to improve the structural rigidity of the rigid roof 100 and the effect of transmitting horizontal loads, the rigid roof 100 also includes a first radial support assembly 70 located between the rigid pressure ring 10 and the rigid pull ring 20, and rigidly connected to the rigid pressure ring 10 and the annular assembly 40 adjacent to the rigid pressure ring 10.

[0121] Among the multiple annular components 40, the annular component 40 adjacent to the rigid pressure ring 10 is defined as the second annular component 42, so a second support space can be formed between the rigid pressure ring 10 and the second annular component 42, and the second support space is the annular space formed between the rigid pressure ring 10 and the second annular component 42.

[0122] A second support space can be formed between the rigid pressure ring 10 and the second annular component 42 adjacent thereto, and since the rigid pressure ring 10 and the second annular component 42 are connected to the radial connection component 30, and there are multiple radial connection components 30 between the rigid pressure ring 10 and the rigid pull ring 20, the radial connection component 30 can divide the second support space into multiple second support units 62. Since there are multiple second support units 62, the first radial support component 70 can be arranged in the multiple second support units 62, and the multiple first radial support components 70 can equally divide the internal force from the rigid pressure ring 10 and the second annular component 42 and the adjacent radial connection components 30, so that the internal force borne by each group of first radial support components 70 is reduced, thereby improving the structural stability of the first radial support components 70.

[0123] The first radial support assembly 70 is provided in at least two second support units 62, that is, several of the plurality of second support units 62 can be selected to set the first radial support assembly 70, but the selection of the second support unit 62 should be symmetrical with respect to the center of the rigid pressure ring 10, so as to ensure the uniformity of the support effect of the first radial support assembly 70 on the rigid roof 100, and not cause a certain local rigidity to be larger and the other positions to be smaller, so as to prevent the first radial support assembly 70 from affecting the stability of the overall structure of the rigid roof 100. Of course, if the building form is relatively special, that is, the building structure is an asymmetric structure, or the load borne by the rigid roof 100 is relatively special, for example, when strong winds, rain and snow often appear in the environmental load, it is known through force analysis that a certain part of the second support unit 62 of the rigid roof 100 needs to be structurally strengthened, then the selection of the second support unit 62 where the first radial support assembly 70 needs to be set can be determined according to the force analysis. In summary, the selection of the second support unit 62 provided with the first radial support assembly 70 should be selected based on the stress analysis requirements of the overall structure to ensure that the first radial support assembly 70 can improve the overall rigidity of the rigid roof 100.

[0124] Specifically, see Fig.17 The first radial support assembly 70 includes a third oblique rod 71 and a fourth oblique rod 72, and the third oblique rod 71 and the fourth oblique rod 72 are cross-connected in the second support unit 62, and in each second support unit 62, a group of cross-connected third oblique rods 71 ​​and fourth oblique rods 72 are rigidly connected. Exemplarily, taking the second support unit 62 as an approximate fan-shaped annular unit as an example, the fan-shaped annular unit includes four nodes, namely a fifth node 621, a sixth node 622, a seventh node 623, and an eighth node 624, wherein the fifth node 621 is formed by connecting one of two adjacent radial connection assemblies 30 and the second annular assembly 42, the sixth node 622 is formed by connecting the other of the two adjacent radial connection assemblies 30 and the second annular assembly 42, the seventh node 623 is formed by connecting one of the two adjacent radial connection assemblies 30 and the rigid pressure ring 10, and the eighth node 624 is formed by connecting the other of the two adjacent radial connection assemblies 30 and the rigid pressure ring 10. Two ends of the third oblique rod 71 are connected to the fifth node 621 and the eighth node 624 respectively, and two ends of the fourth oblique rod 72 are connected to the sixth node 622 and the seventh node 623 respectively.

[0125] Arranging the first radial support assembly 70 on the second support unit 62 through the intersection of the third diagonal rod 71 and the fourth diagonal rod 72 can improve the structural stability of the second support unit 62. At the same time, the first radial support assembly 70 can better withstand the load from the horizontal direction, and can effectively prevent the radial connection assembly 30 from being deformed under the action of the horizontal load, that is, the third diagonal rod 71 and the fourth diagonal rod 72 can push and pull the two adjacent radial connection assemblies 30. When the horizontal load causes the two adjacent radial connection assemblies 30 to generate forces in opposite directions, in the absence of the support of the third diagonal rod 71 and the fourth diagonal rod 72, the two adjacent radial connection assemblies 30 will be deformed by approaching each other, and at the same time, the spacing between the two adjacent radial connection assemblies 30 will be reduced, while the distance from other radial connection assemblies 30 will be increased. When the third diagonal rod 71 and the fourth diagonal rod 72 are arranged between two adjacent radial connection components 30, the third diagonal rod 71 and the fourth diagonal rod 72 can generate a force to resist the deformation of the radial connection component 30, and at the same time can transmit the external horizontal load to other second support units 62 connected thereto, so as to weaken the influence of the horizontal load on a certain second support unit 62, and weaken the local force by the overall structure being subjected to force, so as to prevent the local deformation caused by excessive local force, thereby affecting the stability of the entire structure.

[0126] At the same time, since the third diagonal rod 71 and the fourth diagonal rod 72 are connected to the nodes of the radial connection component 30 and the rigid pressure ring 10 and the annular component 40, the third diagonal rod 71 and the fourth diagonal rod 72 can also support the rigid pressure ring 10 and the second annular component 42 adjacent thereto. The supporting effect and supporting function produced can be referred to the above analysis of the adjacent radial connection component 30, which will not be repeated here.

[0127] It can be understood that when the annular component 40 has only one circle, the annular component 40 adjacent to the rigid pressure ring 10 and the rigid pull ring 20 is the same annular component 40, that is, the annular component 40 divides the space between the rigid pressure ring 10 and the rigid pull ring 20 into a first support space and a second support space to respectively arrange the annular support component 50 and the first radial support component 70.

[0128] In some embodiments, in order to improve the structural rigidity of the rigid roof 100 and the effect of transmitting horizontal loads, the rigid roof 100 also includes a second radial support assembly 80 located between the rigid compression ring 10 and the rigid pull ring 20 and rigidly connected to two adjacent annular assemblies 40.

[0129] Among the multiple annular components 40, the annular component 40 that is neither adjacent to the rigid pressure ring 10 nor adjacent to the rigid pull ring 20 is defined as the third annular component 43, and a third supporting space can be formed between two adjacent third annular components 43, and the third supporting space is the annular space formed between the two adjacent third annular components 43.

[0130] And since two adjacent third annular components 43 are connected to the radial connection component 30, and there are multiple radial connection components 30 between two adjacent third annular components 43, the radial connection component 30 can divide the third support space into multiple third support units 63. Since there are multiple third support units 63, the second radial support component 80 can be arranged in the multiple third support units 63. The multiple second radial support components 80 can equally divide the internal force from the adjacent annular components 40 and the adjacent radial connection components 30, so that the internal force borne by each group of second radial support components 80 is reduced, thereby improving the structural stability of the second radial support component 80.

[0131] At least two of the third support units 63 are provided with a second radial support assembly 80, that is, several of the plurality of third support units 63 can be selected to be provided with the second radial support assembly 80, but the selection of the third support unit 63 should be symmetrical with respect to the center of the rigid pressure ring 10, so as to ensure the uniformity of the support effect of the second radial support assembly 80 on the rigid roof 100, and not cause a certain local rigidity to be larger and the other positions to be smaller, so as to prevent the second radial support assembly 80 from affecting the stability of the overall structure of the rigid roof 100. If the building form is relatively special, for example, the building structure is an asymmetric structure, the load borne by the rigid roof 100 is relatively special, and it is known from the force analysis that a certain part of the third support unit 63 of the rigid roof 100 needs to be structurally strengthened, then the selection of the third support unit 63 where the second radial support assembly 80 needs to be provided can be determined according to the force analysis. In short, the selection of the third support unit 63 provided with the second radial support assembly 80 should be selected according to the force analysis of the overall structure, so as to ensure that the second radial support assembly 80 can play an effect of improving the overall rigidity of the rigid roof 100.

[0132] Specifically, see Fig.18The second radial support assembly 80 includes a fifth oblique rod 81 and a sixth oblique rod 82, which are cross-connected in the third support unit 63, and each third support unit 63 is rigidly connected with a group of cross fifth oblique rods 81 and sixth oblique rods 82. Exemplarily, taking the third support unit 63 as a fan-shaped annular unit, the fan-shaped annular unit includes four nodes, namely a ninth node 631, a tenth node 632, an eleventh node 633, and a twelfth node 634, wherein the ninth node 631 is formed by connecting one of two adjacent radial connection assemblies 30 and one of the two third annular assemblies 43, the tenth node 632 is formed by connecting the other of the two adjacent radial connection assemblies 30 and one of the two third annular assemblies 43, the eleventh node 633 is formed by connecting one of the two adjacent radial connection assemblies 30 and another of the two third annular assemblies 43, and the twelfth node 634 is formed by connecting the other of the two adjacent radial connection assemblies 30 and another of the two third annular assemblies 43. Two ends of the fifth oblique rod 81 are connected to the ninth node 631 and the twelfth node 634 respectively, and two ends of the sixth oblique rod 82 are connected to the tenth node 632 and the eleventh node 633 respectively.

[0133] Arranging the second radial support assembly 80 on the third support unit 63 through the intersection of the fifth diagonal rod 81 and the sixth diagonal rod 82 can improve the structural stability of the third support unit 63. At the same time, the second radial support assembly 80 can better withstand the load from the horizontal direction, and can effectively prevent the two adjacent third annular assemblies 43 from being deformed under the action of the horizontal load, that is, the fifth diagonal rod 81 and the sixth diagonal rod 82 can push and pull the two adjacent third annular assemblies 43. When the horizontal load causes the two adjacent third annular assemblies 43 to generate forces in opposite directions, in the absence of the support of the fifth diagonal rod 81 and the sixth diagonal rod 82, the two adjacent third annular assemblies 43 will be deformed by approaching each other, and at the same time, the distance between the two adjacent third annular assemblies 43 will be reduced, while the distance from other annular assemblies 40 will be increased. When the fifth diagonal rod 81 and the sixth diagonal rod 82 are arranged between two adjacent third annular components 43, the fifth diagonal rod 81 and the sixth diagonal rod 82 can generate a force to resist the deformation of the third annular component 43, and at the same time can transfer the external horizontal load to other third support units 63 connected thereto, so as to weaken the influence of the horizontal load on a certain third support unit 63, and weaken the local force by the overall structure, so as to prevent the local deformation caused by excessive local force, thereby affecting the stability of the entire structure.

[0134] At the same time, since the fifth diagonal rod 81 and the sixth diagonal rod 82 are connected to the connection nodes between the radial connection component 30 and the two adjacent third annular components 43, the fifth diagonal rod 81 and the sixth diagonal rod 82 can also support the adjacent radial connection components 30. The supporting effect and supporting function generated can be referred to the above analysis of the adjacent third annular components 43, and will not be repeated here.

[0135] It can be understood that, in the above-mentioned rigid roof 100, the rigid connection methods mentioned, such as the rigid connection between the rigid pull ring 20 and the top of the building, the rigid connection between the rigid pull ring 20 and the second end 32 of the radial connection assembly 30, can all be welding. The specific welding form and welding method can be selected based on force analysis and construction conditions, and are not specifically limited in this embodiment.

[0136] For example, Fig.18 , 19 As shown, Fig.18 In the structure of the rigid roof 100, the structures of the rigid compression ring 10 and the rigid tension ring 20 are both solid steel beams, the structure of the radial connection component 30 is a plane truss, and the structure of the annular component 40 is a plane truss.

[0137] When the environmental loads such as wind loads in the environment where the rigid roof 100 is located are relatively complex, a first diagonal rod 61 and a second diagonal rod 62 may be provided between the first annular component 41 of the rigid roof 100 and the rigid pull ring 20 to improve the ability of the rigid roof 100 to resist horizontal loads. At the same time, a third diagonal rod 71 and a fourth diagonal rod 72 may be provided between the second annular component 42 of the rigid roof 100 and the rigid pressure ring 10 to improve the ability of the rigid roof 100 to resist horizontal loads. A fifth diagonal rod 81 and a sixth diagonal rod 82 may be provided on two adjacent third annular components 43 of the rigid roof 100 to further improve the ability of the rigid roof 100 to resist horizontal loads.

[0138] When the span of the rigid roof 100 is large, the required size of the rigid roof 100 is large, and the structural deadweight of the rigid roof 100 becomes large. In order to better transmit the self-weight of the rigid roof 100, ensure the stability of the internal force of the rigid roof 100, and achieve the stability of the overall structure of the rigid roof 100, the structure of the radial connection component 30 can be selected as a plane truss structure. At the same time, in order to effectively prevent the structural instability of the radial connection component 30, it can be supported by setting the first annular component 41, the second annular component 42 and the plurality of third annular components 43, and the structure of the first annular component 41, the second annular component 42 and the plurality of third annular components 43 can be selected as a plane truss structure to better help the radial connection component 30 to transmit the internal force, so as to achieve the self-balancing system of the rigid roof 100. In addition, the plane truss structure of the radial connection component 30 and the plane truss structure of the first annular component 41, the second annular component 42 and the plurality of third annular components 43 can help the rigid roof 100 better resist the effect of external loads to ensure the stability of the structure.

[0139] It can be understood that the shape of the plane truss in the plane truss structure of the radial connection component 30 and the plane truss structure of the first annular component 41, the second annular component 42 and the multiple third annular components 43, as well as the arrangement and connection positions of the upper chord, the lower chord, the diagonal web and the vertical rods in the truss structure can be designed and arranged through force analysis, and are not specifically limited in the present embodiment, but all of its rods are rigid rods, and the connections between the rigid rods are rigid connections to ensure the rigidity of the structure.

[0140] Second, see Fig. 20 The embodiment of the present invention provides a building 200, which includes the rigid roof 100 as described in the first aspect, and the rigid roof 100 is arranged on the top of the building 200 to shield the internal structure of the building 200, and the rigid roof 100 can also realize the lighting of the building 200. The building 200 can be a building such as a stadium, an activity center, etc. that requires an opening design on the top.

[0141] For further information, see Fig.21The rigid roof 100 can be connected to the top 210 of the building 200 through a movable hinge support 220. The movable hinge support 220 includes a fixed end 221 and a connecting end 222. The relative positions of the fixed end 221 and the connecting end 222 in the horizontal direction are movable. The fixed end 221 is connected to the building 200, and the connecting end 222 is rigidly connected to the rigid pull ring 20 of the rigid roof 100. From the force analysis of the first aspect above, it can be seen that when the rigid roof 100 is connected to the top 210 of the building 200 through the movable hinge support 220, the movable hinge support 220 can constrain the vertical displacement of the rigid roof 100 and release the horizontal displacement of the rigid roof 100 at the same time, so as to reduce the horizontal force acting on the top 210 of the building 200 from the rigid roof 100, and can effectively reduce the boundary conditions of the top 210 of the building 200. Calculations have shown that when the top 210 of the building 200 is connected to the rigid roof 100 by a movable hinge support 220, the vertical and horizontal displacements of the rigid roof 100 only need to increase by about 10 mm, which is a very small deformation relative to the entire main body of the building 200. This means that the structural stability of the rigid roof 100 can be ensured, while reducing the pressure on the top 210 of the building 200, thereby reducing the requirements for the construction of the building 200.

[0142] See also Fig. 22 The third aspect of this embodiment provides a construction method of the rigid roof as described in the first aspect above, and the construction method comprises the following steps:

[0143] S1. Install the rigid pull ring to the top of the building;

[0144] S2. Install a temporary bracket inside the rigid pull ring;

[0145] S3, installing the radial connection assembly, rigidly connecting the radial connection assembly to the rigid pull ring and allowing the temporary bracket to be supported by the radial connection assembly;

[0146] S4, installing the rigid pressing ring, and making the rigid pressing ring be located inside the rigid pull ring, and making the rigid pressing ring be connected to the radial connection assembly;

[0147] S5. Remove the temporary support.

[0148] It is understandable that during the construction process, the rigid pull ring 20 is first installed on the top 201 of the building. The rigid pull ring 20 can be formed by welding multiple rigid rods one by one on the top of the building, or it can be formed partially or in whole in a factory and then hoisted to the top 201 of the building for installation by a large hoisting device. The specific form of the rigid pull ring 20 depends on the hoisting capacity of the hoisting device at the construction site to facilitate installation. The same is true for the formation process of the radial connection assembly 30 and the rigid pressure ring 10, which will not be repeated here.

[0149] Specifically, Fig.23 As shown, the temporary support 101 can be installed at a position where the distance between the connection point between the temporary support 101 and the radial connection component 30 and the rigid pressure ring 10 is half the distance between the connection point between the radial connection component 30 and the rigid pull ring 20, that is, the distance between the connection point between the temporary support 101 and the radial connection component 30 and the rigid pressure ring 10 is the distance between the connection point between the radial connection component 30 and the rigid pressure ring 10 and the connection point between the radial connection component 30 and the rigid pull ring 20. Fixing the temporary support 101 near this position can ensure that the radial connection component 30 can be better supported, so as to ensure that the subsequent installation of the rigid pressure ring 10 can be more stable. At the same time, the structural stability of the rigid roof 100 can be achieved when the temporary support 101 is removed.

In summary, the content of this specification should not be understood as a limitation on the present invention.
