Assembled sash beam and design method thereof
The invention discloses an assembly type sash beam and a design method thereof. The assembly type sash beam comprises compartments formed by assembling steel beams and cross-shaped connecting pieces. Cross-shaped connecting pieces are arranged at the four corners of each compartment, steel beams are arranged on the four edges of each compartment, and the two ends of each steel beam are connected with the corresponding cross-shaped connecting pieces. A first anchor rod is arranged at the cross-shaped connecting piece, and the bottom of the first anchor rod is anchored into the side slope; a mother mesh is arranged in the compartment, and a mounting area is reserved in the middle of the mother mesh; the sub-mesh is mounted in the mounting area, and the periphery of the sub-mesh is connected with the mother mesh through springs; a second anchor rod is arranged in the middle of the sub-mesh, and the bottom of the second anchor rod is anchored into the side slope so as to apply prestress to the sub-mesh and the main mesh, so that the sub-mesh and the main mesh apply pressure to the side slope. The split mounting type lattice beam has the advantages of being low in cost, short in construction period and high in adaptability to geological conditions, prestress applied by the second anchor rods can enable the sub-meshes and the mother meshes to apply pressure to dangerous rocks on a side slope, and the risk that the dangerous rocks slide down is reduced.
本发明公开了一种拼装式框格梁及其设计方法，所述拼装式框格梁包括由钢梁和十字连接件拼装形成的隔间；隔间的四个角均设有十字连接件，四条边均设有钢梁，钢梁的两端均与十字连接件相连；十字连接件处设置有第一锚杆，第一锚杆底部锚入边坡中；隔间中设置有母网片，母网片中间预留有安装区域；子网片安装在所述安装区域中，子网片四周通过弹簧与母网片连接；子网片中部设置有第二锚杆，第二锚杆底部锚入边坡中，以对子网片和母网片施加预应力，使子网片和母网片对边坡施以压力。本发明的拼装式框格梁具有成本低、施工周期短、对地质条件适应性强的优点，且第二锚杆施加的预应力可使子网片、母网片对边坡上的危岩施加压力，减轻危岩滑落的风险。
