Column caps:
Column caps, also known as post pallets, in slab column - shear wall structure when no-slab construction, according to the requirements of the bearing capacity and deformation-free column cap plate or column caps (column Torr) plate form. Column caps (column pallets) to calculate the length and thickness shall be determined in each direction and a length of not less than 1/6 of the span plate, the thickness of not less than the plate thickness of 1 / 4.7-degree cap should be used when there is column (column bracket board), 8 degrees should be used pillared cap (column tray).

Column cap features:
Using one for mine (column caps) field with column shoes specially modified nylon composite material, which has been modified nylon mainly in the following aspects:
1.Improve the water absorption of nylon, improve the dimensional stability of products;
2. Improve flame retardant nylon to meet the requirements of underground work;
3. Improve the mechanical strength of the nylon, in order to achieve strength of the metal material, thereby replacing metal;
4. Improve resistance to low temperature performance nylon, enhance their ability to respond to the environment;
5. Improve the wear resistance of nylon to meet the abrasion resistance requirements of the occasion;
6.Improve nylon antistatic properties to meet the requirements of mining and mechanical applications;
7. Nylon reduce costs, improve product competitiveness.
