Abstract

The invention relates to a truss connection structure, more specifically a floor truss pin shaft connection node structure, including a floor kingpin, a middle sliding sleeve, an adjusting screw sleeve, a truss side bar, a reinforcing bar, an adjusting support bar and a top frame , the middle sliding sleeve is slidably connected to the middle end of the floor kingpin, and the adjusting screw sleeve is connected to the upper end of the floor kingpin through thread fit, and spring I and spring II are sleeved on the floor kingpin, and the spring I and spring II are respectively located at the upper and lower ends of the middle sliding sleeve, and the left and right ends of the middle sliding sleeve are respectively hingedly connected with the lower end of a truss side bar. The invention can adjust the height of the top frame by adjusting the screw sleeve; through the middle sliding sleeve, spring I and spring II, the force of the top frame can be cushioned; by pushing and pulling the connecting rod and the elastic support rod, the top frame can be raised The support span of the elastic support rod is increased at the same time, so as to ensure the stability of the structure.

Description

technical field [0001] The invention relates to a truss connection structure, in particular to a ground truss pin shaft connection node structure. Background technique [0002] For example, the patent application number is CN201510984907.0, a ground truss pin connection node structure, which includes a connecting bracket and a pre-embedded steel plate. The connecting bracket includes a main chord, a top plate, a web and a bottom plate. The top plate is herringbone bent The plate includes a first connecting portion and a second connecting portion connected in sequence, the main chord includes a first chord and a second chord, and the first chord and the second chord are respectively perpendicular to and fixed to the first The top of the connecting part and the second connecting part, the web is fixed between the top plate and the bottom plate, the lower end of the bottom plate is provided with a first connecting piece extending vertically downward along its end surface, and t...
