Hinged supports
are divided into two types: movable hinged supports and grid fixed hinged supports
.
The sliding hinge support cannot move in the vertical direction, but can rotate and move in the horizontal direction.
The component and the support are connected with pins, and the support can move along the supporting surface. This constraint can only restrict the movement of the component in the direction perpendicular to the supporting surface, but cannot prevent the component from rotating around the pin and moving along the supporting surface. direction of movement. Therefore, the action point of its constraint reaction force is the contact point between the constraint and the constrained object. The constraint reaction force passes through the center of the pin and is perpendicular to the supporting surface. The direction may be toward the component or away from the component, depending on the active force.
The grid fixed hinged support
can rotate, but cannot move horizontally or vertically.
The component and the support are connected with a smooth cylindrical hinge. The component cannot move in any direction, but can rotate around the pin. It can be seen that the constraint reaction force of the fixed hinge support is the same as the cylindrical hinge constraint, that is, the constraint reaction force is certain Acts on contact point, through center of pin, direction undetermined.
Network frame fixed hinged support
The diameter of the hinged column foot ground anchor is determined according to the principle of coordination with the thickness of the steel column plate and the thickness of the bottom plate, and is not less than the diameter of the column foot ground anchor. The main function of the ground anchor is to install In fixing projects, it is often seen that there are four ground anchors at a column corner, and there are also two ground anchors, etc., which are generally determined based on the cross-sectional form, size, and installation requirements. For light steel structures with rigidly connected column feet, the bending moment and shear force are often large, while the axial force is relatively small, so the design requirements for column foot shear resistance are more stringent. The existence of bending moment and anchor bolt pretightening force will affect the shear resistance of rigidly connected column feet, which will directly increase the shear bearing capacity of rigidly connected column feet.

/>Technical indicators of grid fixed hinged supports
The supports can be divided into fixed supports according to their performance, which only have vertical rotation performance, code-named.
, One-way movable bearing, with vertical rotation and single-direction sliding performance, code-named.
, two-way movable bearing, with vertical rotation and longitudinal and lateral sliding properties, code-named.
, Applicable temperature range and friction coefficient Normal temperature bearings are suitable for ℃~+℃, what is the minimum design friction coefficient?
Cold-resistant bearings are suitable for ℃~+℃, and the minimum design friction coefficient is Value?
If the customer chooses cold-resistant bearings, they must indicate it when signing the agreement.
Maintenance methods for grid fixed hinged supports

Check whether the supports and upper and lower connections are damaged, check whether the bolts are sheared or loose, and whether the welds are cracked, etc.
. Check the dust accumulation in the dust cover and remove the dust.
. Check the rubber sealing ring for cracks and aging.
Turn the fixing nut, clean it and re-oil it to avoid rust.
. Check the height change of the support itself. This change reflects the wear of the PTFE plate. When the height change exceeds mm, it should be overhauled.
. Check the integrity of the anti-rust paint. If there is any peeling off, use emery cloth to grind out the steel body and show the metallic luster before repainting.
