Technical parameters of spherical steel support for grid support with ball hinge


The technical parameters of ball hinge support for the lower grid are introduced by the manufacturer of the spherical grid support


1. Vertical bearing capacity of bearings is divided into 14 grades of 300KN~10000KN


2. The horizontal resistance of the bearing is 20% of the vertical bearing capacity;


3. Vertical tension resistance of support: GKQZ type GJQZ type are 20% of the vertical bearing capacity; The resistance to vertical tension of GKGZ type GJGZ type is 30% of the vertical bearing capacity;


4. Design corner is 0.08rad (it can be designed separately according to user requirements)


5. The radial displacement of the bearing is ±20mm-±50mm, the circular displacement is ±60mm-±100mm; The above technical requirements can be designed produced according to customer requirements.

The connection form of the installation scheme of the spherical steel support of the grid frame should be specifically agreed with the structural designer to ensure the reliable connection function of the upper lower structure support. The mark number of the reinforced concrete column under the spherical steel support of the grid frame shall be lower than Grade C40. The reinforcement in the column of spherical steel support of the grid frame should refer to the research analysis results in the design of this support, that is, the configuration of horizontal stirrup section with enlarged section should be within the height range of 0.25b to 0.6b the top of the column along the column axis along the column foot (b is the column width), the increment should be determined according to the analysis results of bearing capacity. The movable support of the spherical steel support of the grid frame shall set the deviation value between the upper support plate the sliding plate according to the design requirements. If welding is adopted for the connection between the spherical steel support of the grid frame the embedded steel plate, cooling measures should be taken the method of intermittent welding on the opposite side should be adopted to prevent the overheating of the steel support damaging the polyfour plate, rubber sealing ring silicone grease. The elevation levelness of the substructure should meet the design requirements before the installation of the spherical steel support of the grid frame. ㎜ four corners are better than 1㎜.
