Description

Technical Field

[0001] The utility model relates to the technical field of building structures, in particular to a support integrated combined node and a building suitable for a cable tensioning location of a tensioned lattice shell. Background Art

[0002] The string-and-string lattice shell structure is a new type of prestressed spatial structural system. It uses prestressing to reduce deadweight, improve structural stability, and achieve self-balancing. This structural system consists of an upper lattice shell, lower vertical struts, radial tie rods or cables, and circumferential cables, forming a complete structural system with a clear force transmission path. The application of this structural system not only improves building safety but also opens up new possibilities for architectural design, allowing architects to create more aesthetically pleasing and innovative architectural forms while meeting functional requirements.

[0003] To achieve self-balancing in a cable-tensioned lattice shell, the connection of the cable tensioning points is crucial. Furthermore, since the lattice shell members are mostly square tubes, this connection is even more difficult. Because the cable tensioning points are difficult to connect to the lattice shell, some cable tensioning points are disconnected from the lattice shell and installed directly on the columns below the supports. However, this also places new load requirements on the columns at the supports. Utility Model Content

[0005] The technical solution adopted by the present invention to solve the above technical problems is:

[0007] According to the above technical solution, the upper surface of the ear plate is connected to the bottom of the upper shell by welding, and the lower surface of the ear plate is connected to the top of the lower cylinder by welding.

[0008] According to the above technical solution, a connection surface with the same inclination angle as the upper surface of the ear plate is provided at the bottom of the upper shell, and a connection surface with the same inclination angle as the lower surface of the ear plate is provided at the top of the lower cylinder.

[0009] According to the above technical solution, a base plate and a support seat are also provided on the top of the lower cylinder. The support seat is fixed to the top of the support column by bolts, embedded parts, or welding. The base plate is welded to the upper surface of the support seat, and the bottom of the lower cylinder is welded to the upper surface of the base plate.

[0010] According to the above technical solution, the upper shell adopts a spherical cap structure.

[0011] According to the above technical solution, the upper shell adopts a hemispherical shell, and the lower cylinder adopts a columnar structure with the same cross-section as the horizontal projection of the hemispherical shell.

[0012] According to the above technical solution, a cross inner reinforcing plate is provided in the lower cylinder, the top of the inner reinforcing plate is welded to the lower surface of the ear plate, the side of the descending plate is welded to the inner wall of the lower cylinder, and the inner reinforcing plate is welded to the bottom plate.

[0014] According to the above technical solution, on the projection of the horizontal plane, a lattice shell member rib is provided on the lattice shell member corbel where the angle with the projection of the ear plate is within the set range; the lattice shell member rib is connected between the lattice shell member corbel and the upper shell body, between the lattice shell member corbel, the ear plate and the upper shell body, and between the ear plate and the lower cylinder body.

[0015] According to the above technical solution, the setting range is 5°

[0016] A building, characterized by comprising any of the above described support integrated combination nodes suitable for the cable tensioning position of a string-type lattice shell.

[0017] The utility model has the following beneficial effects:

[0018] 1. A combined node is formed by combining ear plates, an upper shell, a lower cylinder, and a base plate. Multiple lattice shell rod brackets connect all lattice shell rods at this connection point to the combined node. The ear plates are connected between the bottom of the upper shell and the ends of the cables, thereby applying prestress to the lattice shell structure. The cables, ear plates, upper shell, lower cylinder, lattice shell rod brackets, and lattice shell now form a single, stable, and self-balancing structure. The lower cylinders at multiple nodes then support this entire structure at the support columns, completing the installation of the lattice shell structure.

[0019] In the above process, the ear plates, upper shell, and lower cylinder are combined to form the core of the composite node. This can be prefabricated directly in the factory according to the design drawings. The connection points of the lattice rods, cables, and support columns can all be pre-set. Using this composite node, the composite node can be first installed on the support column, and then the cables and lattice rods can be installed on the support column. Compared with the existing technology that first installs the cables on the lattice shell and then installs the lattice shell on the support column, the configuration of the component node separates the installation process of the cables and lattice shell. While quickly achieving the force mode, it also simplifies the installation process of the cables and lattice shell, speeding up installation and improving construction efficiency.

[0020] 2. Since only a few lattice shell member brackets bear large tensile forces, lattice shell member ribs are only set in the lattice shell member brackets that bear large tensile forces to avoid the influence of temperature on the nodes when the lattice shell member ribs are welded on the structure.

[0021] 3. An inner stiffener is installed inside the lower cylinder, and the inner diameter plate is connected between the ear plate and the bottom plate to improve the structural strength of the lower cylinder.

[0037] Example 1

[0038] The invention comprises a cable 1, a lattice shell rod 2 arranged in the lattice shell, and a lattice shell support column 3; an ear plate 4, an upper shell 5, a lower cylinder 6, and a lattice shell rod bracket 7; the ear plate adopts a plate-like structure, one end of which is connected to the cable and maintains the same inclination angle as the cable; the upper shell is located on the top of the lower cylinder, and the other end of the ear plate is connected between the upper shell and the lower shell; the contact positions of the upper shell and the lower cylinder on the ear plate are vertically aligned with each other; one end of a plurality of lattice shell rod brackets is welded and fixed to the outer wall of the upper shell, the ear plate, and the lower cylinder, and the other end of the lattice shell rod brackets is connected to the corresponding lattice shell rods respectively; the bottom of the lower cylinder is directly or indirectly fixed to the support column. Some lattice shell rod brackets are welded and fixed to the outer wall of the upper shell, some lattice shell rod brackets are welded and fixed to the upper shell and the ear plate, and some lattice shell rod brackets are welded and fixed to the outer wall of the upper shell, the ear plate, and the lower cylinder.

[0039] In this embodiment, the ear plate is fixedly connected between the upper shell and the lower cylinder, and the three constitute an integral part; since the ear plate is connected between the upper shell and the lower cylinder, it is ensured that the ear plate is provided with two welding surfaces between the upper shell and the lower cylinder, thereby improving the welding strength of the ear plate between the upper and lower shells, ensuring that the ear plate can be stably fixedly connected to the support column indirectly through the upper shell and the lower cylinder when the ear plate is under tension.

[0040] In Example 1, preferably, the upper surface of the ear plate is welded to the bottom of the upper shell, and the lower surface of the ear plate is welded to the top of the lower cylinder. Furthermore, a connecting surface having the same inclination angle as the upper surface of the ear plate is provided on the bottom of the upper shell, and a connecting surface having the same inclination angle as the lower surface of the ear plate is provided on the top of the lower cylinder.

[0041] Example 2

[0042] The structure and principle of Example 2 are similar to those of Example 1, except that: in order to ensure the reliability of the connection of the lower cylinder to the support column, a base plate 8 and a support seat 9 are further provided on the top of the lower cylinder. The support seat is fixed to the top of the support column by bolts, embedded parts, or welding. The base plate is welded to the upper surface of the support seat, and the bottom of the lower cylinder is welded to the upper surface of the base plate.

[0043] In Examples 1 and 2, the upper shell adopts a spherical cap structure. Several lattice shell member brackets are connected to the upper shell. The spherical cap structure of the upper shell facilitates balancing the forces from the individual lattice shell member brackets, allowing the entire structure to quickly reach a state of force equilibrium at the component nodes.

[0044] Example 3

[0045] The structure and principle of Example 3 are similar to those of Example 2, except that:

[0046] Preferably, the upper shell is a hemispherical shell, and the lower cylinder is a columnar structure with the same cross-section as the horizontal projection of the hemispherical shell (its cross-section is elliptical). In order to improve the structural strength of the lower cylinder, a cross-shaped inner reinforcement plate 10 is provided in the lower cylinder. The top of the inner reinforcement plate is welded to the lower surface of the ear plate, the side of the lower plate is welded to the inner side wall of the lower cylinder, and the inner reinforcement plate is welded to the bottom plate.

[0047] In Example 3, the number of lattice shell rod brackets is determined by the number of lattice shell rods at the node. One end of the lattice shell rod bracket is provided with a mounting cavity that matches the dimensions of the lattice shell rod connection end. One end of the lattice shell rod bracket is welded to the outer wall of the upper shell, the ear plate, and the lower cylinder. The lattice shell rods are placed in the mounting cavity and fixed therein by welding.

[0048] Example 4

[0049] The structure and principle of Example 4 are similar to those of Examples 1-3, with the difference being that, in order to reduce the influence of temperature on the nodes during welding, it is comprehensively considered that only the lattice shell members in the same direction as the cables are subjected to greater forces. In the projection on the horizontal plane, a lattice shell member rib 11 is provided on the lattice shell member corbel where the angle with the ear plate projection is within a set range; the lattice shell member rib is connected between the lattice shell member corbel and the upper shell, as well as between the lattice shell member corbel, the ear plate and the upper shell, and between the ear plate and the lower cylinder.

[0050] Preferably, the setting range is 5°, that is, the angle between the lattice shell member corbel and the ear plate in the projection on the horizontal plane does not exceed 5°, so the lattice shell member rib can be set on the corbel.

[0051] The utility model also provides a building, comprising any one of the above described support integrated combination nodes applicable to the cable tensioning position of the string-type lattice shell.

[0052] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any ordinary technician in this industry can smoothly implement the present invention as shown in the drawings and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with this profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the scope of protection of the technical solution of the present invention.
