Description

Technical Field

[0001] The invention belongs to the technical field of single-layer lattice shell connection nodes, and in particular to a folded plate node structure suitable for single-layer lattice shells. Background Art

[0002] The folded plate node structure is suitable for single-layer lattice shells. The node domain consists of core components and nested standard H-shaped steel splicing nodes and corresponding H-shaped steel rods. The core components include a central circular tube, an upper bent multi-panel, a lower bent multi-panel and a web connecting plate. Inside the core component, the web connecting plate is continuous by inserting a central circular tube between the web connecting plates with different surfaces in space. Between the upper and lower bent multi-panel outer eaves with different surfaces in space, the upper and lower bent multi-panels are respectively continuous by two folding methods of central surface configuration or outer eave surface configuration, thereby realizing a rigid connection between H-shaped steel rods. The folded plate node connection structure in normal use has a single shape of connecting pipe fittings, and the number of connections is generally 5-6, and the quantity adjustment range is limited.

[0003] An existing support system for a large-scale oblique woven node plate grid shell structure is very common during use, and the existing splicing method is mutually spliced ​​when in use, mainly using the central folded plate node assembly as the main connection center, and assembling after plugging in the connecting rods. However, the central rod plug-in hole of the folded plate node assembly serving as the main connection has an adjustment range. First, when assembling a single-sided grid shell, it is necessary to make a variety of folded plate node assemblies with different opening directions to meet the plug-in connection of the connecting rods. At the same time, when installing the glass, it is necessary to weld the support frame or directly weld the support frame to the outside of the triangular buckle. During installation and adjustment, the installation order of the glass may be affected, and during the gluing operation, the glass fixing operation is not easy to operate, and multiple screws need to be tightened and fixed, which slows down the construction progress of the single-sided grid shell.

[0004] Therefore, a folded plate node structure suitable for single-layer lattice shells is proposed to address the above problems. Summary of the invention

[0064] The top of the single-layer lattice shell 1 is welded with a folded plate node assembly 2 and a connecting rod 4 to form a top surface.

[0065] The lattice shell dome 3 and the connecting rod 4 are mainly made of 6061-T6 aluminum alloy, and the lattice shell dome 3 composed of the folded plate node assembly 2 and the connecting rod 4 is made of 6061-T6 aluminum alloy as a whole, which enhances the anti-corrosion performance and ensures the strength of the structure to avoid collapse caused by gravity. A single folded plate node assembly 2 can connect up to 14 connecting rods 4. The triangular groove 209 can be opened into different slot hole structures during production to connect connecting rods 4 of different shapes. By opening different slot hole structures, connecting rods 4 of different shapes can be plugged in and positioned, and different connecting rod 4 structures can be installed.

[0066] Among them, the building structure composed of glass 6 and single-layer grid shell 1 is an existing technology. On this basis, the connection method and connection quantity of the folded plate node assembly 2 of the single-layer grid shell 1 are adjusted and innovated, which will not be repeated.

[0067] The working principle of the technical solution provided by the present invention is as follows:

[0068] When the folding plate node assembly 2 of the single-layer lattice shell 1 is produced, it is made into a special spherical positioning block 201 structure. At the same time, the spherical positioning block 201, the connecting shaft 202, the rotating square block 203 and the tightening block 205 located inside the rotating square block 203 that are spliced ​​on the outside of the folding plate node assembly 2 are all provided with holes and grooves on the surface of the structure. The holes and grooves are mainly triangular holes and grooves, which have a more beautiful appearance. If there are other building facilities, the triangular holes and grooves can be opened into the shape of circular, square, elliptical and other connecting rods 4 for quick alignment and splicing. If no other shapes are needed, triangular grooves 1 208, triangular grooves 209, triangular grooves 3 211, triangular grooves 4 212 and triangular grooves 5 215 can be opened directly in sequence, and the end plugs are inserted into the corresponding triangular grooves. Then the connecting rods 4 are inserted into the outside of the end plugs, and they are shaped. Welding is performed. After welding is completed, the unnecessary protrusions are polished off to make its surface smoother. The rotating square block 203 can be inserted into the outside of the spherical positioning block 201 located in the middle position through the connecting shaft 202, and the side ball block 213 is installed to the outside of the connecting shaft 202. The pin 216 is inserted into the inside of the triangular groove 215 and rotated and tightened. It is positioned on the outside of the connecting shaft 202 through the threaded groove. The side ball block 213 can be rotated to adjust the orientation of the casting node 214. The tightening block 205 inside the rotating square block 203 is clamped into the inside of the arc groove 210 of the spherical positioning block 201. The tightening block 205 is clamped inside the arc groove 210 for positioning. After the assembly is completed, the spring 207 outside the damping rod 206 can be stretched and pushed to bounce open, and the tightening block 205 can be pressed against the inside of the arc groove 210 to keep it in position.

[0069] During the connection operation of the connecting rod 4, different connecting rods 4 can be placed near the folding plate node assembly 2 for standby use. According to the requirements of the architectural construction drawing of the single-layer lattice shell 1, the rotating square block 203 structure located outside the spherical positioning block 201 can be rotated to adjust it to different arc grooves 210, or rotated to the corner position, and the triangular groove 209 on the surface of the rotating square block 203 is moved and changed. The end plug is inserted and pre-assembled with the connecting rod 4. The side ball block 213 structure outside the connecting shaft 202 can be adjusted to adjust the casting node of the side ball block 213. After the point 214 is rotated to a different orientation, according to the above scheme, the connecting rod 4 is assembled to the outside of the casting node 214 and welded and fixed. The connection method is more convenient and flexible. When the side ball block 213 is rotated and adjusted, the anti-slipping strip 204 can be used to prevent it from slipping off. The pressing plate 506 structure is rotated, and the positioning shaft 507 of the pressing plate 506 moves inside the guide groove 505. After rotating to a position flush with the cross plate 502, the positioning shaft 507 structure located inside the guide groove 505 can be moved horizontally to the left, and the surface of the support plate 503 and the cushion layer 504 at the bottom of the pressing plate 506 can be matched. The structure is pressed against the outer surface of the glass 6 to stably position it and maintain stability during the connection process. At the same time, after the glass 6 is initially positioned, the fastening screw 702 in the glass adjustment assembly 7 can be inserted into the interior of the limiting ring 706 and screwed into the interior of the socket 701 to tighten it for positioning. After the positioning is completed, the spring 2 704 sleeved on the outside of the vertical shaft 705 can be used to push the limiting ring 706 structure to be pressed against the surface of the rotating ring 709 to keep the rotating ring 709 rotating on the surface of the pressure plate 506. The long rod on the other side can be driven by pulling the handle 707 at the top of the short rod 710. 708 rotates, and during the rotation process, the long rod 708 can drive the internal cross bar 711 to move, stretch and adjust, control the adjustment rod 713 structure inside the clamp block 712 to move up and down, control the internal adjustment rod 713 structure to slide up and down, and can cooperate with the clamp block 712 to clamp and position the side plate 715 structure. After completing the limit, it can remain stable. The adjustment rod 713 pulls the glass 6 to push it close to the top of the support plate 503 on the other side, pushes it tightly, and keeps the glass 6 and the glass clamping assembly 5 stable in the subsequent gluing state to avoid glue deflection and affect the appearance.
