Embodiment Construction

[0010] As shown in Figure 1, the universal joint unit of the structural member of the present invention is composed of a thrust joint bearing 1, a thrust joint bearing 2, a fixed base 3, a fixed cover plate 4, a high-strength fixing bolt 5, a nut 6, a washer 7 and a mandrel 8 , it is characterized in that: the thrust joint bearing 1 and the thrust joint bearing 2 are installed in pairs on one end of the mandrel 8, the pair of thrust joint bearings and the mandrel are put into the inner hole of the fixed base 3 together, and there is a fixed cover with a hole in the middle The plate 4 covers the large end face of the seat ring of the thrust joint bearing 2, and is connected with the fixed base 3, and is fixed by a plurality of high-strength fixing bolts 5, nuts 6, and washers 7 to form a hinged unit structure. The thrust joint bearing is made of stainless steel.

[0011] During installation, the end of the fixed base in the hinge unit is connected with a component of the buildi...

Abstract

The invention discloses a hardware universal hinging unit, which consists of a pair of thrust articulated bearings, a mandrel, a fixed base, a fixed cover plate, a bolt, a nut and a washer. The pair of thrust articulated bearings are matched and connected with the mandrel; housing washer excircles of the pair of thrust articulated bearings are matched with an inner bore of the fixed base; the fixed cover plate is pressed on the housing washer of one of the thrust articulated bearings and locked with each other through the bolt, the nut and the washer to form the hinging unit; a fitting surface between the thrust articulated bearings and the housing washer is a spherical surface and the two can be relatively rotated, so a member connected with the other end of the mandrel and a member connected with the end of the fixed base can be rotated in all directions in the circumference; a hinging function node with multi-direction rotation is realized, surface outer shearing force or additional bending moment loaded on the hardware can be effectively unloaded, and the safety of a building element is ensured; and the thrust articulated bearings are made of stainless steel, so the hardware universal hinging unit has a rust-proof function.

Description

technical field [0001] The invention relates to a universal hinge unit of a structural part, in particular to a universal hinge unit of a building steel structure. Background technique [0002] Hinge joints are often used in building steel structures, but conventionally used hinge joints are generally one-way rotating joints such as pin shafts or high-strength bolt ear-plate connections. For space structural systems with complex forces, the joints generally have two directions. Shear force, so the joint needs to have the ability to rotate in both directions in order to meet the structural requirements. At present, there are not many joints that can meet the rotation requirements of two directions or more than two directions, especially the joints that can be used for beam end supports have not been used yet. The design of the invention applies the joint bearing to the hinge node to realize the hinge function node with multi-directional rotation. Contents of the invention ...
