[0002] The grid frame is a space structure formed by connecting multiple rods through nodes according to a certain grid form. It has the advantages of space force, light weight, high rigidity, and good seismic performance. The typical structure of the grid frame is a double-layer structure. That is, the upper chord is connected by bolt balls to form the upper chord surface, the lower chord is connected by bolt balls to form the lower chord surface, and the upper chord surface and the lower chord surface are connected by web bars. Some bolt holes extend along the centerline of the bolt ball, so that the upper chord, lower chord and other members can coincide with the centerline of the bolt ball; Use needs, when the strength of the checked structure cannot meet the use function and original design requirements, there is a great potential safety hazard

Embodiment Construction
[0022] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0023] Such as Figure 1 to Figure 5 Shown; the present invention is a grid reinforcement connection structure, including the original grid 1, the new grid 2, the first connecting piece 3 and the second connecting piece 4; the lower chord surface of the original grid 1 has a first bolt ball 11 And the second bolt ball 12; the lower end of the first bolt ball 11 has existing bolt holes for installation. The existing bolt holes mentioned here refer to the bolt holes that can be used; the upper chord surface of the newly added grid 2 has a third Bolt ball 21 and fourth bolt ball 22; the upper end of the first connecting piece 3 is screwed into the existing bolt hole, and the lower end of the first connecting piece 3 is screwed into the first bolt hole provided at the upper end of the third bolt ball 21; The upper end of the second connecting p...

The invention discloses a connecting structure for net rack reinforcement. The connecting structure comprises an original net rack, a newly added net rack, first connecting pieces and second connecting pieces, wherein the lower chord plane of the original net rack is provided with first bolt balls and second bolt balls, the lower ends of the first bolt balls are provided with bolt holes for installation, the upper chord plane of the newly added net rack is provided with third bolt balls and fourth bolt balls, the upper ends of the first connecting pieces are screwed into the bolt holes, the lower ends of the first connecting pieces are screwed into first bolt holes formed in the upper ends of the third bolt balls, the upper ends of the second connecting pieces are welded to the lower endsof the second bolt balls, and the lower ends of the second connecting pieces are screwed into second bolt holes formed in the upper ends of the fourth bolt balls. By integrally connecting the originalnet rack and the newly added net rack, it is ensured that the two racks are jointly stressed, and improvement of the overall strength is facilitated.
Description
Technical field [0001] The invention belongs to the technical field of grid frames, and specifically relates to a connection structure for reinforcing grid frames. Background technique [0002] The grid is a spatial structure formed by multiple rods connected by nodes in a certain grid form. It has the advantages of space stress, light weight, high rigidity, and good seismic performance; the typical structure of the grid is a double-layer structure. That is, the upper chord is connected by the bolt ball to form the upper chord surface, the lower chord is connected by the bolt ball to form the lower chord surface, and the upper and lower chord surfaces are connected by the web rod. For the bolt ball, in order to avoid the force deflection, the bolt ball is installed Some bolt holes extend along the centerline of the bolt ball, so that the upper chord, lower chord and other members can coincide with the centerline of the bolt ball; after the grid structure is built and used, the gr...
