Compact four-beam anchor rod suitable for space-limited anchoring system
The invention relates to a compact four-beam anchor rod suitable for a space-limited anchoring system, which comprises a web plate, a bearing plate, a locking plate, a stiffening plate and a flange, the web plate comprises a slotted web plate section, and web plate slots are symmetrically formed in the slotted web plate section along the center line; the bearing plates are fixedly connected to the two sides of the middle of the web. The locking plate is arranged on the lower side of the bearing plate and fixedly connected to the middle of the web. One side of the stiffening plate is fixed on the bearing plate, and the other side of the stiffening plate is fixedly connected to the slotted web section; the flanges are fixedly arranged on the two sides of the bearing plate. The reinforcing structure has the beneficial effects that 1, the grooves are formed in the web plates, and the whole stiffening plate is adopted for fixing, so that the overall stress performance is good, and the stress concentration phenomenon is avoided; 2, under the condition that the number of main cable strands is large, the number of anchor rods can be reduced, and the steel consumption of an anchoring system is reduced; and 3, through a welding mode, the use of a high-strength bolt is avoided, and the service life of the anchor rod is prolonged.
本发明涉及一种适用于空间受限锚固系统的紧凑型四束锚杆，包括腹板、承压板、锁定板、加劲板及翼缘，腹板包括开槽腹板段，开槽腹板段沿中线对称设有腹板开槽；承压板固定连接于腹板的中部两侧；锁定板设于承压板下侧，且固定连接于腹板的中部；加劲板一侧固定在承压板上，另一侧固定连接于开槽腹板段；翼缘固定设于承压板两侧。本发明的有益效果在于：1、通过在腹板处开槽，且采用整块的加劲板固定，使整体受力性能好且没有应力集中现象；2、通过本申请可在主缆索股数量较多的情况下，减少锚杆的数量，减少锚固系统的用钢量；3、通过焊接的方式，避免了高强度螺栓的使用，增加了锚杆的使用寿命。
