A new type of assembled large-span rod cable structure

Abstract

This invention relates to the field of building structure technology, specifically to a novel prefabricated large-span cable-stayed structure, comprising component modules, connecting modules, and adjusting modules. Multiple component modules are sequentially overlapped to form a mutually supporting structure, with each module supporting the others to achieve a complete and independent support structure. The connecting modules prevent relative movement between the first and second components, increasing their stability. During normal use, the force acting on the second component is concentrated in its center. The adjusting modules distribute the localized force evenly across the entire second component, preventing uneven stress and thus avoiding bending. With the second component subjected to uniform stress, the overall stiffness of the overlapping component modules is improved, thereby extending the overall service life of the overlapping component modules.

Description

Technical Field

[0001] This invention relates to the field of building structure technology, specifically to a novel prefabricated large-span cable-stayed structure. Background Technology

[0002] An interlocking structure is a type of rod-like structure characterized by multiple overlapping members. These members support each other in a cyclical manner, with each member supporting others while being supported in return. These opposing forces bring the members into equilibrium. An interlocking structure is a flat, hierarchical structure; there is no clear unidirectional hierarchy among the members, and all members are equally important. The dispersed nodes of an interlocking structure prevent multiple members from sharing a single node, thus simplifying node construction. Furthermore, the rhythmic and aesthetically pleasing arrangement of the members in an interlocking structure makes it a popular choice among architects.

[0003] Compared to conventional grid structures, inter-support structures have weaker stiffness. In an inter-support structure, one component uses the mid-span of an adjacent component as a fulcrum. Under load, the deformation of the entire structure accumulates, resulting in very low overall stiffness and a short service life. Therefore, there is an urgent need for a geometric configuration to improve the overall stiffness of inter-support structures. Summary of the Invention

[0004] This invention provides a novel prefabricated long-span cable-stayed structure to solve the problem of low overall stiffness in existing inter-support structures.

[0005] The present invention provides a novel prefabricated long-span cable-stayed structure using the following technical solution:

[0006] A novel prefabricated long-span cable-stayed structure includes component modules, connection modules, and adjustment modules.

[0007] There are multiple component modules, each of which includes a first component and two second components. The two second components are connected to both ends of the first component. The two second components on any component module overlap the first component in the adjacent component module. A connection module is used to connect the first component and the second component. There are multiple adjustment modules, each of which is used to evenly distribute the force acting on a local part of the second component across the entire second component.

[0008] Furthermore, the adjustment module includes a strut and a cable. The strut is vertically positioned at the middle of the length of the second component. Both ends of the cable are connected to the second component. The cable is connected to the second component near the end of the second component. The middle of the cable abuts against the end of the strut away from the second component. The cable is in a taut state.

[0009] Furthermore, within the same component module, two second components are located in the same plane, with the first component positioned above the second components and the strut positioned below the second components.

[0010] Furthermore, the connection module includes a first connection block and a second connection block, both of which are fixedly mounted on the second component. The first connection block is used to connect the first component and the second component in the same component module, and the second connection block is used to connect the first component and the second component in two adjacent component modules.

[0011] Furthermore, the longitudinal section of the second component is set as a quadrilateral; the first connecting block and the second connecting block are located on two opposite side walls of the second component, the second connecting block is located at the end of the second component, and the first connecting block is located in the middle of the second component.

[0012] Furthermore, each second component is provided with a third connecting block, which is used to connect the strut to the second component.

[0013] Furthermore, both the third connecting block and the second connecting block are disposed on the downward-facing side wall of the second component.

[0014] Furthermore, the upper end of the strut is connected to the third connecting block, and the lower end of the strut is equipped with a fixed pulley, with the cable passing around the fixed pulley.

[0015] Furthermore, each second component is provided with two lifting rings, the ends of the cable are connected to the lifting rings, and the two lifting rings are located between the two second connecting blocks.

[0016] Furthermore, the longitudinal section of the first component is set to be circular.

[0017] The beneficial effects of this invention are as follows: This invention provides a novel prefabricated large-span cable-stayed structure, comprising component modules, connecting modules, and adjusting modules. By setting multiple component modules to be sequentially overlapped to form a mutually supporting structure, each component module supports the others, thus achieving a complete and independent support structure. Under the action of the connecting modules, the relative movement between the first and second components is less likely to occur, increasing the stability between the first and second components. During normal use, the force acting on the second component is concentrated in the middle of the second component. Under the action of the adjusting modules, the force acting on the second component is evenly distributed across the entire second component, avoiding uneven stress on the second component and thus preventing bending. After the second component is evenly stressed, the overall stiffness of the overlap of multiple component modules is improved, thereby increasing the overall service life of the overlap of multiple component modules.

[0032] like Figures 1 to 9 As shown in the figure, an embodiment of the present invention provides a novel prefabricated long-span cable-stayed structure, which includes a component module, a connection module, and an adjustment module.

[0033] Multiple component modules are provided, each including a first component 110 and two second components 120, with the two second components 120 connected to both ends of the first component 110. The two second components 120 of any component module overlap the first component 110 of an adjacent component module. Multiple component modules can be stacked sequentially to form a mutually supporting frame. Each component module is both a support and a supported element, and all component modules are of equal importance and are indispensable parts of the structure.

[0034] The connecting module connects the first component 110 and the second component 120. The connecting module prevents slippage during the overlap of the first component 110 and the second component 120, thereby improving the stability of the resulting inter-support structure. Multiple adjustment modules are provided, one on each second component 120. Each adjustment module distributes the force acting locally on the second component 120 evenly across the entire second component 120. With the action of multiple adjustment modules, the force on the multiple second components 120 is uniform, thus improving the overall stiffness of the inter-support frame structure composed of multiple component modules.

[0035] This invention discloses a novel prefabricated long-span cable-stayed structure. Multiple component modules are sequentially interlocked to form a mutually supporting structure, with each module supporting the others to create a complete and independent support structure. The connecting modules prevent relative movement between the first component 110 and the second component 120, increasing their stability. During normal use, the force acting on the second component 120 is concentrated in its center. With the adjustment module, the force acting locally on the second component 120 is evenly distributed across the entire component, preventing uneven stress and bending. After the second component 120 is evenly stressed, the overall stiffness of the interlocking component modules is improved, thus extending the overall service life of the interlocking component modules.

[0036] In one embodiment, the adjustment module includes a strut 130 and a cable 140. The strut 130 is vertically disposed at the middle of the length direction of the second component 120. After the second component 120 is compressed, the compressed point on the second component 120 is prone to deformation. By setting the position of the strut 130 on the second component 120, when the second component 120 is compressed, the force on the second component 120 can be synchronously transmitted to the strut 130. Both ends of the cable 140 are connected to the second component 120. The cable 140 is connected to the second component 120 near the end of the second component 120. The middle part of the cable 140 abuts against the end of the support rod 130 away from the second component 120. The cable 140 is in a taut state. In this state, the cable 140 and the second component 120 form a closed triangle. When the support rod 130 is subjected to force, the force on the support rod 130 acts on the middle part of the cable 140. Since the cable 140 is in a taut state in the initial state, when the middle part of the cable 140 is squeezed by the support rod 130, the cable 140 transmits the force on the support rod 130 back to both ends of the second component 120. This allows the force acting locally on the second component 120 to be adjusted to the entire second component 120, thereby preventing local deformation of the second component 120.

[0037] In one embodiment, within the same component module, two second components 120 are located in the same plane, with a first component 110 positioned above the second component 120 and a support rod 130 positioned below the second component 120. It is understood that the two second components 120 on any component module overlap with the first component 110 in an adjacent component module. That is, in any component module, the force on the second component 120 originates from the first component 110. By positioning the support rod 130 and the first component 110 in opposite directions on the second component 120, it is ensured that the force on the second component 120 can be transmitted to the support rod 130, thereby ensuring that the cable 140 can adjust the force on the support rod 130 to the entire second component 120.

[0038] In one embodiment, the connection module includes a first connecting block 150 and a second connecting block 160. Both the first connecting block 150 and the second connecting block 160 are fixedly disposed on the second component 120. The first connecting block 150 is used to connect the first component 110 and the second component 120 in the same component module, and the second connecting block 160 is used to connect the first component 110 and the second component 120 in two adjacent component modules. In a specific configuration, each second component 120 is provided with one first connecting block 150 and two second connecting blocks 160. The first connecting block 150 is disposed in the middle of the second component 120 along its length, and the two second connecting blocks 160 are disposed at both ends of the second component 120 along its length. In a further configuration, both the first connecting block 150 and the second connecting block 160 are provided with insertion holes 161, and the first component 110 can be inserted into the insertion holes 161. By using the first connecting block 150 and the second connecting block 160, the construction speed can be improved. The connection between the first component 110 and the second component 120 by using the first connecting block 150 and the second connecting block 160 is not restricted by weather conditions, and the quality of the connection between the first component 110 and the second component 120 can be improved, while reducing labor input.

[0039] In one embodiment, the longitudinal section of the second component 120 is set as a quadrilateral, and the second component 120 is set as a rectangular rod. When the second component 120 is placed, it has an upper sidewall and a lower sidewall. The first connecting block 150 and the second connecting block 160 are located on the two opposite sidewalls of the second component 120. In a specific arrangement, the first connecting block 150 is set on the upper sidewall of the second component 120, and the second connecting block 160 is set on the lower sidewall of the second component 120. The two second connecting blocks 160 are located at both ends of the length direction of the second component 120, and the first connecting block 150 is located in the middle of the length direction of the second component 120. The positions of the first connecting block 150 and the second connecting block 160 are clearly defined, which facilitates mass production in the production workshop.

[0040] In one embodiment, each second component 120 is provided with a third connecting block 170, which is used to connect the support rod 130 to the second component 120. Specifically, the third connecting block 170 is located on the lower sidewall of the second component 120, and at the middle of the length of the second component 120. The third connecting block 170 has a mounting hole 171 and a first locking screw, which is arranged radially along the mounting hole 171. When the first locking screw is rotated, its end can enter the mounting hole 171. The support rod 130 can be inserted into the mounting hole 171. When the support rod 130 is inserted into the mounting hole 171, rotating the first locking screw causes it to abut against the support rod 130, thereby fixing the support rod 130 to the third connecting block 170 and preventing the support rod 130 from detaching from the second component 120.

[0041] In one embodiment, the upper end of the strut 130 is connected to the third connecting block 170, and the lower end of the strut 130 is provided with a fixed pulley 131. The cable 140 is arranged to pass around the fixed pulley 131. The fixed pulley 131 can reduce the wear of the cable 140, thereby improving the service life of the cable 140.

[0042] In one embodiment, each second component 120 is provided with two lifting rings 180. The end of the cable 140 is connected to the lifting ring 180. The two lifting rings 180 are disposed between two second connecting blocks 160. In a specific configuration, the lifting ring 180 is provided with a threaded rod. The lower side wall of the second component 120 is provided with two threaded holes. The threaded rod on the lifting ring 180 can be inserted into the threaded holes, which improves the convenience of installing the lifting ring 180. By using the lifting ring 180 to connect the cable 140 and the second component 120, the construction cycle is shortened while ensuring the connection strength, thus improving the overall ease of installation.

[0043] In one embodiment, the longitudinal section of the first component 110 is set to be circular. In this embodiment, the first component 110 is set as a round rod, and the insertion hole 161 on the first connecting block 150 and the insertion hole 161 on the second connecting block 160 are both set as annular. A second locking screw is provided on both the first connecting block 150 and the second connecting block 160. The second locking screw is set along the radial direction of the insertion hole 161 and can enter the insertion hole 161. When the first component 110 is inserted into the insertion hole 161, by rotating the second locking screw, the second locking screw abuts against the first component 110, thereby fixing the first component 110 on the first connecting block 150 or the second connecting block 160 and preventing the first component 110 from detaching from the second component 120.

[0044] In one embodiment, the first connecting block 150, the second connecting block 160 and the third connecting block 170 are all fixed to the second member 120 using high-strength screws.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
