Description

Technical Field

[0001] The invention relates to the technical field of slope support construction, and in particular to an assembled lattice beam, which is mainly fixed to the outer side of a slope rock and soil body for supporting the slope. Background Art

[0002] Anchor frame beams are often used for support in excavation slope support. The main process is to construct anchor cables or anchor rods on the slope after excavation, and then cast the lattice beams, that is, tie steel bars, support formwork, and pour concrete on the slope. After the age of the lattice beams, the support is completed after tensioning and locking the anchor cables or anchor rods.

[0003] There are several construction difficulties in this construction plan: 1) After the excavation forms a slope, the construction position of the lattice beam is located in the middle of the slope, which requires the establishment of scaffolding and increases the risk of high-altitude operations; 2) Since the slope formed by excavation has a certain slope, the angle is mostly 45-60°, and the steel bar binding and formwork on the slope require additional fixing measures, and it is difficult to ensure the construction accuracy; 3) Since the lattice beam is set on the slope, the beam surface will also be an inclined surface, which makes it very difficult to pour concrete; 4) It takes 14-28 days to proceed to the next step.

[0004] Therefore, the research purpose of the present invention is to design an assembled lattice beam that can prefabricate lattice beams, guide and install the prefabricated lattice beams smoothly, and enable the prefabricated lattice beams to form a stable support on the outside of the slope.

[0007] A plurality of rows of corresponding supporting balls are installed side by side at intervals on the guide rod. After the limiting pipe of the prefabricated lattice beam is inserted into the guide rod, the outer ends of the supporting balls roll and abut against the inner side wall of the limiting pipe.

[0008] Hanging rings corresponding to the fixed ear plates are fixedly connected to both sides of the steel wire rope, and the fixed ear plates and the hanging rings are hinged through corresponding hinge shafts.

Under the guiding action of the guide rod 402, the prefabricated lattice beam 3 is tilted until the guide rod 402 and the locking rod 102 are in a straight line, and the guide rod 402 no longer rotates under the fixation of the latch 5; then, the hoisting height of the prefabricated lattice beam 3 is controlled to be lowered. Under the guiding action of the guide rod 402, the prefabricated lattice beam 3 is assembled to the slope 2 where the locking rod 102 is located, and the locking rod 102 is plugged into the limiting pipe 303 of the prefabricated lattice beam 3; Locking nut 8, after the prefabricated lattice beam 3 is assembled to the slope position where the locking rod 102 is located, the fixing sleeve 401 is removed, and the locking nut 8 is locked to the end of the locking rod 102 to fix the prefabricated lattice beam 3.
