When making plastic mountain landscape, it is generally necessary to weld steel structure skeleton to support plastic mountain modeling. Small plastic mountain landscape uses angle steel structure, large plastic mountain body uses channel steel or I-beam steel and other large steel structures. The steel structure is fixed by welding and anchoring. The concrete fixing method of plastic mountain skeleton is introduced below.
I. Connection and Reinforcement and Connection of Reinforcement Parts
The connection method of steel structure is weld, rivet, ordinary bolt and high strength bolt. It should be strengthened according to the reasons, purposes, structure and construction conditions. At the same time, the original connection method of the structure should be considered.
Steel structure reinforcement is generally more suitable for weld connection, friction type high strength bolt connection, can also be based on weld and friction type high strength bolt hybrid connection, when using weld connection, it is necessary to adopt approved welding technology and connecting materials.
2. Reinforcement of Increased Section of Members
When strengthening steel members with enlarged cross-section, the selected cross-section form should be conducive to the technical requirements of strengthening, and the existing defects and damage conditions should also be taken into account. After section reinforcement is completed, specific measurements are needed to determine the fixed firmness.
3. Crack Repair and Reinforcement
Because of repeated loading and improper material selection, construction, manufacture, construction and installation, the plastic mountain skeleton tends to be fragile and tends to star crack damage. We should try to repair it. Before repair, we should analyze the causes and seriousness of the cracks, and take targeted measures to improve the actual work of the structure or reinforce the plastic mountain. It is not suitable to use repairing and reinforcing components, so they should be demolished and replaced.
The above reinforcement methods are the main fixing methods of the plastic mountain skeleton. After all welding and anchorage are completed, they should be measured, and rust-proof and corrosion-proof treatment should be carried out at the same time. After the fixing of the skeleton, the surface of the plastic mountain will be made, and the welding of the surface steel bar and the skeleton will determine the overall shape of the plastic mountain.
