The structural form of large sculptures and the precautions when making them

Large sculptures are a beautiful landscape in the city. Large sculptures generally have a load-bearing main steel frame structure. For different large sculptures, the structure of the steel frame is different. The following Beijing Sculpture Company will introduce to you The structural form of large sculptures and the precautions for their manufacture. One, the structural form of large sculptures 1, the reinforced concrete frame structure of the reinforced concrete frame structure of the statue is similar to the general construction project, it is mainly composed of reinforced concrete beams and columns cast-in-place The advantage is that the overall rigidity of the structure is relatively large, and the project cost is low; the disadvantage is that compared with the steel structure, the self-weight, the construction period is long, and the connection with the auxiliary support is inconvenient. 2. The reinforced concrete tube of the reinforced concrete tube structure statue The body structure is similar to the tube structure in high-rise buildings, and it can be designed as a cylinder, square tube or elliptical tube. Its advantages are that the overall rigidity of the structure is large, the wind resistance and seismic performance are good, and it is easy to combine with the use of the elevator shaft; The disadvantage is that it is only suitable for standing statues with relatively regular vertical shapes, which are usually referred to as standing statues. Generally, they can be connected with the auxiliary brackets and wall panels by setting up the auxiliary frame structure. 3. The steel truss structure of the steel truss structure statue is made of Steel rods such as square steel pipes, round steel pipes or angle steels are hinged structures formed by connecting surfaces of gusset plates. The advantage is that the connection requirements between the rods are not high, bolts or welding can be used, the construction difficulty is low, and the structure is light. , It is easier to meet the requirements of the outer contour of the statue by setting the rods in any direction of the space. Generally, there is no need to set up the auxiliary frame structure, and it can be directly connected to the auxiliary bracket; the disadvantage is that the overall rigidity of the structure is not large enough, and a large number of Oblique support rods can form a truss structure with geometric triangles, and the internal members are messy and complicated. 4. The steel frame structure of the steel frame structure statue is generally made of H-shaped steel or channel steel, large-section square steel pipe and other rods rigidly connected. The advantage of the rigid frame structure is that in addition to the advantages of the steel truss structure, there are fewer or no diagonal support members, the internal space is relatively simple, and the construction speed is fast; the disadvantage is that the connection requirements between the members 5. Steel grid structure The steel grid structure of the statue is a bolt ball or welded ball space grid structure formed by steel pipes through high-strength bolts or directly welded to processed steel balls. Its advantage is that the rod The processing of nodes and nodes can be carried out on special equipment, and its production efficiency and processing accuracy are high, and the on-site assembly speed is fast; the disadvantage is that it is not suitable for irregularly shaped statue structures, otherwise due to the irregular angle between a large number of rods , There are too many types of nodes, installation is difficult, and the overall cost is high. Second, the precautions for the production of large-scale sculptures 1. When connecting the vertical members on the periphery of the image, the actual outer contour of the image may exist between certain two layers of curves. The concave part, at this time, some components at this place may conflict with the position of the wall plate for the second installation, which is the so-called violation. 2. At the sudden change of the contours of the body, head, and neck of the statue, the mesh of the rods should be changed. The grid is appropriately refined and subdivided to facilitate a reasonable transition; 3. For slender parts such as arms and streamers, single-leg multi-fold rods should be used; 4. When the head has backlight, wall and other parts, it can be made of H-shaped steel. Or a single-layer grid structure composed of square steel pipes. It is an introduction to the structure of large-scale sculptures and the precautions when they are manufactured. I hope it can help you.
