Description

Technical Field

[0001] The utility model relates to the technical field of industry, in particular to a quick-fastening and clamping mining column shoe column cap. Background Art

[0002] The column cap of non-metallic monomer pillar is based on nylon polymer, which is suitable for point column support or local support of monomer pillars in coal mines. It is positioned by the top cover claws on the upper part of the monomer pillar and padded between the top of the monomer hydraulic pillar or all metal friction pillars in the coal mine and the roof. The column cap is also called the column support plate. When the plate-column-shear wall structure adopts a beamless plate structure, it can be used in the form of a column cap-free plate or a column cap (column support) plate according to the bearing capacity and deformation requirements. The length and thickness of the column cap (column support plate) should be determined by calculation, and the length in each direction should not be less than 1 / 6 of the plate span, and its thickness should not be less than 1 / 4 of the plate thickness. It is advisable to use a column cap (column support plate) for 7 degrees, and a column cap (column support plate) for 8 degrees. For specific requirements, refer to the relevant content and data of JGJ3-2010 "Technical Code for Concrete Structures of High-rise Buildings".

[0003] After searching, the Chinese patent publication number CN203891903U discloses a quick-fastening and clamping mining column shoe cap, including a supporting bottom surface, a limiting slot is provided at the center of the supporting bottom surface, the complete end of the elastic split half-tube is installed in the installation slot of the limiting slot, the other end of the elastic split half-tube is provided with a V-shaped groove, and the elastic split half-tube is externally threaded and connected to the fastening nut, and a number of reinforcing ribs are provided between the limiting slot and the supporting bottom surface, and the supporting bottom surface is covered with a layer of anti-slip sleeve. The above patent has the following shortcomings: Although the patent can fix the hydraulic support, the fixing method is to fix it by multiple bolts. Therefore, when the hydraulic support needs to be repaired, it takes a lot of time to disassemble the multiple bolts, so the maintenance efficiency becomes low. In view of this, we propose a quick-fastening and clamping mining column shoe cap. Utility Model Content
