Description

Technical Field

[0001] The present invention belongs to the technical field of single-layer lattice shell connection nodes, and in particular relates 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 grid shells. The node domain consists of core components and nested standard H-shaped steel splicing nodes and corresponding H-shaped steel members. The core components include a central circular tube, an upper bent multi-panel, a lower bent multi-panel and a web connection plate. Inside the core component, the web connection plate is continuous by inserting a central circular tube between the web connection plates with different spatial surfaces. Between the upper and lower bent multi-panel outer eaves with different spatial surfaces, the upper and lower bent multi-panels are respectively continuous through two folding methods, namely, a central surface configuration or an outer eaves surface configuration, thereby realizing a rigid connection between the H-shaped steel members. The folded plate node connection structure connection fittings in normal use have a single shape, and the number of connections is generally 5-6, and the quantity adjustment range is limited.

[0003] The existing support system of 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 folding plate node assembly as the main connection center, and assembling after plugging in the connecting rods. However, the central rod plug-in of the folding plate node assembly as the main connection is fixed, and the adjustment range is first. When assembling the single-sided grid shell, it is necessary to make a variety of folding 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, it may affect the installation order of the glass, 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, to address the above problems, a folded plate node structure suitable for single-layer lattice shells is proposed. Summary of the Invention

By opening different slot 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] During the production of the folding plate node assembly 2 of the single-layer lattice shell 1, 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 other shapes are not required, triangular groove one 208, triangular groove two 209, triangular groove three 211, triangular groove four 212 and triangular groove five 215 can be opened directly in sequence, the end core is inserted into the corresponding triangular groove, and then the connecting rod 4 is inserted into the outside of the end core, and it is Welding is carried out. After the 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 5 215 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, and the tightening block 205 inside the rotating square block 203 is clamped into 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 1 207 on the outside of 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 maintain positioning.

[0069] During the connection operation of the connecting rod 4, different connecting rods 4 can be placed near the folding plate node assembly 2 and wait for standby. According to the requirements of the construction drawing of the single-layer lattice shell 1, the rotating square block 203 structure located on the outside of the spherical positioning block 201 can be rotated to adjust it to different arc grooves 210, or rotated to the corner position, and the orientation of the triangular groove 209 on the surface of the rotating square block 203 is changed. The end core is inserted into the pre-assembly with the connecting rod 4, and the side ball block 213 structure on the outside of 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-slip strip 204 can be used to prevent it from slipping off. The pressure plate 506 structure is rotated, and the positioning shaft 507 of the pressure plate 506 moves inside the guide groove 505. After it is rotated to a position flush with the horizontal plate 502, the positioning shaft 507 structure inside the guide groove 505 can be moved horizontally to the left to cooperate with the surface of the support plate 503 and the pad 504 at the bottom of the pressure plate 506. 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 inside of the limiting ring 706 and screwed into the inside of the socket 701 to tighten the position. After the positioning is completed, the spring 2 704 set 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, keeping the rotating ring 709 rotating on the surface of the pressure plate 506, and 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 the long rod 708 can drive the internal cross bar 711 to move and stretch during the rotation, control the adjustment rod 713 structure inside the clamp 712 to move up and down, and control the internal adjustment rod 713 structure to slide up and down, and can cooperate with the clamp 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 and pushes it close to the support plate 503 on the other side, pushing it tightly, and keeping the glass 6 and the glass clamping assembly 5 stable in the subsequent gluing state to avoid glue deflection and affect the appearance.
