Description

Technical Field

[0001] This invention relates to the technical field of structural engineering, specifically to adjustable hyperboloid space frame units and space frame structures. Background Technology

[0002] In recent years, space frame structures have been widely used in large-span landmark civil buildings such as convention centers, stadiums, and airports due to their advantages such as reasonable stress distribution, lightweight and material-saving construction, and short construction period. However, traditional space frame structures have relatively simple forms and cannot meet the requirements of irregular structures; at the same time, they are difficult to coordinate changes and develop diverse structures for the deformation of large-space structures. Summary of the Invention

[0003] This invention addresses the problems mentioned in the background art by proposing an adjustable hyperboloid space frame unit and space frame structure. It not only meets the mechanical performance requirements of large-span roof structures, but also solves the deformation coordination problem of uniquely shaped irregular structures and large-span space structures, while promoting the development of space frame structures in my country.

[0004] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows:

[0005] An adjustable hyperboloid space frame unit consists of two identical bifurcated steel rods, a spring deformation coordinating component, and an adjusting tube. Each bifurcated steel rod includes a rod body with a coordinating component connection port and at least one adjusting tube connection port at its inner end. The number of adjusting tubes is the same as the number of adjusting tube connection ports. The spring deformation coordinating component is an elastic element, with both ends fixed to the coordinating component connection ports of the two bifurcated steel rods. The adjusting tube connection port is equipped with threaded teeth, and the inner cavity of the adjusting tube has threads that mate with the threaded teeth. Both ends of the adjusting tube are inserted into the adjusting tube connection ports of the two bifurcated steel rods. When the adjusting tube rotates, it can pull the two bifurcated steel rods closer together or push them further apart.

[0006] To optimize the above technical solution, the specific measures also include:

[0007] The aforementioned bifurcated steel connecting rod has two adjusting pipe connection ports, correspondingly, there are two adjusting pipes, and the coordinating component connection port is located between the two adjusting pipe connection ports.

[0008] The aforementioned spring deformation coordination component includes a spring connecting rod and a spring. The spring connecting rod is fixedly connected to both ends of the spring and is fixedly connected to the connection port of the coordination component by welding.

[0009] The adjustable hyperboloid space frame structure includes multiple adjustable hyperboloid space frame units and multiple assembly links. Every four adjustable hyperboloid space frame units form a square structure by connecting the outer ends of the link bodies. Each of the four corners of this square structure is fixedly connected to one end of an assembly link, resulting in a total of four assembly links. The other ends of these four assembly links are fixed to each other, forming link endpoints. Thus, four adjustable hyperboloid space frame units and four assembly links together form a unit group. Several unit groups form a space frame structure where all adjustable hyperboloid space frame units are on the same plane, and adjacent unit groups share a common adjustable hyperboloid space frame unit. On the same side, the assembly links are all located on the lower side of the space frame structure. The adjustable hyperboloid space frame unit of the space frame structure forms the upper chord surface. The ends of the links of two adjacent unit groups are fixedly connected by an adjustable hyperboloid space frame unit. The adjustable hyperboloid space frame unit between the ends of the links forms the lower chord surface. The upper chord surface and the lower chord surface are parallel. By adjusting the adjustment tubes of the adjustable hyperboloid space frame unit on the upper chord surface and the lower chord surface, the lengths of the adjustable hyperboloid space frame unit on the upper chord surface and the lower chord surface are made different, which causes the upper chord surface or the lower chord surface to bend in the left-right or front-back direction. Thus, the upper chord surface, the lower chord surface and the assembly links between them together form the hyperboloid space frame.

[0010] The length of the adjustable hyperboloid space frame unit on the lower chord surface of the aforementioned hyperboloid space frame is shorter than the length of the adjustable hyperboloid space frame unit on the upper chord surface, so that the lower chord surface is a plane and the upper chord surface is a curved surface.

[0011] The aforementioned adjustable hyperboloid space frame unit and assembly rods are all made of steel.

[0012] The aforementioned assembly link is a hollow link.

[0013] The other ends of the four assembly links in the aforementioned unit group are fixed to each other by welding to form the link endpoints.

[0014] Compared with traditional roof structures, this invention has the following advantages:

[0015] 1. This invention enables prefabricated construction. After the structural design is completed, each unit and unit group can be prefabricated in the factory, and then quickly installed on the construction site. This simplifies the construction process, improves construction efficiency, reduces the construction period, and meets the need for rapid building construction.

[0016] 2. This invention can solve the coordination problem of irregular spatial grid structures. This patent realizes the deformation transition of irregular spatial grid structures, achieving a unity of construction error, structural error, and deformation coordination.

[0017] 3. This invention offers diverse structural forms. This patent allows for alteration of the overall roof structure by adjusting the number of unit groups and component deformation, resulting in various configurations such as arched roof structures, hyperboloid roof structures, and saddle-shaped curved surface structures. This breaks away from traditional space frame structures, promotes structural innovation, and drives the development of space frame structures in my country.

[0018] 4. This invention has high sustainability. Compared with traditional space frame structures, this invention can change the form of the space frame structure by adjusting the position of the upper and lower chords, thus meeting the roof form requirements of different building structures. It has minimal environmental impact on the construction site, is green and environmentally friendly, and has high sustainability. Attached Figure Description

[0032] Before construction, the structural engineer designed the structural form of the space frame structure for the project, determining the number of unit groups, the number of adjustable hyperboloid space frame units (hereinafter referred to as unit components) required to form the unit groups, and the number of assembly links. Several unit components and assembly links 4 were prefabricated in the factory. The fabrication process for each unit component is as follows: First, two bifurcated steel connecting rods 1, one spring deformation coordination component 2, and two adjusting pipes 3 are prefabricated. Then, the middle parts of the two bifurcated steel connecting rods 1 are welded to both ends of the spring deformation coordination component 2, and the two ends of the two bifurcated steel connecting rods 1 are connected by adjusting pipes 3. According to the design requirements, adjacent unit components are welded to form the upper chord surface. At each welding point, an assembly link 4 is welded, and the other end of the assembly link 4 is welded to the same point, thus completing the fabrication of one unit group. Several unit groups are fabricated repeatedly. During construction, the welding points at the bottom of two unit groups are connected by another unit component, and the operation is repeated to form the required structural form.

[0033] Specifically, each unit group consists of four unit components and four assembly links 4. After the corresponding number of unit components and assembly links 4 are prefabricated, the four unit components are welded in pairs to form the upper chord. Then, an assembly link 4 is welded at each of the four welding points, and the other ends of the four assembly links 4 are welded to the same point.

[0034] The structural forms of unit groups are diverse. They can form spatial space frame structures such as "flat-plate space frame structures", "arched space frame structures", and "hyperbolic space frame structures".

[0035] 1. Flat-plate space frame structure

[0036] The flat-plate space frame structure requires several unit groups, each composed of several unit components. First, two bifurcated steel connecting rods 1, one spring deformation coordinating component 2, and two adjusting pipes 3 are prefabricated. Then, the middle parts of the two bifurcated steel connecting rods 1 are welded to both ends of the spring deformation coordinating component 2. The two ends of the two bifurcated steel connecting rods 1 are then connected by adjusting pipes 3. Adjacent unit components are welded to form the upper chord surface. At each welding point, an assembly connecting rod 4 is welded, with the other end of the assembly connecting rod 4 welded to the same point. The lower parts of two unit groups are connected by a unit component. This process is repeated to ensure that each unit component of the upper chord and the unit components of the lower chord are placed parallel, thus forming the flat-plate space frame structure.

[0037] Arched space frame structure

[0038] An arched space frame structure requires several unit groups, each composed of several unit components. First, two bifurcated steel connecting rods 1, one spring deformation coordinating component 2, and two adjusting pipes 3 are prefabricated. Then, the middle parts of the two bifurcated steel connecting rods 1 are welded to both ends of the spring deformation coordinating component 2, and the two ends of the two bifurcated steel connecting rods 1 are connected by adjusting pipes 3. Adjacent unit components are welded to form the upper chord surface. An assembly connecting rod 4 is welded to each welding point, with the other end of the assembly connecting rod 4 welded to the same point. The lower parts of two unit groups are connected by a single unit component, and this process is repeated. For a unit component in a specific direction (lateral or longitudinal), the spring deformation coordinating component 2 and the bifurcated steel connecting rod 1 of the upper chord are stretched, while the spring deformation coordinating component 2 and the bifurcated steel connecting rod 1 of the lower chord are simultaneously shortened, causing the upper chord to arch upwards, thus forming the arched space frame structure.

[0039] Hyperboloid space frame structure

[0040] The hyperboloid space frame structure requires several unit groups, each composed of several unit components. First, two bifurcated steel connecting rods 1, one spring deformation coordinating component 2, and two adjusting pipes 3 are prefabricated. Then, the middle parts of the two bifurcated steel connecting rods 1 are welded to both ends of the spring deformation coordinating component 2, and the two ends of the two bifurcated steel connecting rods 1 are connected by adjusting pipes 3. Adjacent unit components are welded to form the upper chord surface. An assembly connecting rod 4 is welded to each welding point, with the other end of the assembly connecting rod 4 welded to the same point. The lower parts of two unit groups are connected by a single unit component, and this process is repeated. For the unit components in two directions (lateral and longitudinal), the spring deformation coordinating component 2 and the bifurcated steel connecting rod 1 of the upper chord are stretched, while the spring deformation coordinating component 2 and the bifurcated steel connecting rod 1 of the lower chord are simultaneously shortened, causing the upper chord to arch upwards, thus forming the hyperboloid space frame structure.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of this application.

[0042] Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application. Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
