grid structure

Announce

edit

grid structure It is composed of many continuous bars according to certain rules Reticular structure , add a ball at the contact to increase the link. Members mainly bear Axial force , can give full play to the strength of materials, save steel, Structure dead weight Small. Grid Structural space High rigidity, entirety Strong, good stability. It is built by using smaller rod pieces Large span Structure, and the member type is unified.

suspended-cable structure

Shell structure

suspended-cable structure (A bridge is built between two mountains, and an iron chain is used between the two mountains. This is the structure of the hanging lock. For example, the Red Army passed Luding Bridge ）Yes Large span An ideal structural form of roof. Suspension cable The structure is generally composed of steel cables Edge component And lower part Supporting structure form. For example: Olympic Movement The center is made of suspension cables.

Shell structure

edit

Shell structure There are vertical supports at both ends tangent When the force is decomposed to both sides, the size is very small, and the span can be very large. For example, building arch bridges and large churches.

Pipe truss structure

edit

Tube Truss structure Truss made of steel pipe structural system , so it is also called truss Or pipe structure. As long as the unique structural system is formed by using the superior mechanical performance and beautiful external shape of steel pipe, the latest design concept of steel structure can be met Materials used , load bearing and Stabilization Of Component combination To play the role of space.

membrane structure

membrane structure ( Membrane ）It is a new type developed in the middle of the 20th century Building structure form , is composed of various high-strength Film material ( PVC Or Teflon) and Stiffener (Steel frame Steel column Or steel cable) to generate a certain pretension stress in its interior in a certain way to form a certain spatial shape, as a covering structure, and can withstand a certain external load. Membrane structures can be divided into Inflatable membrane structure and Tensioned Membrane structure Two types. Inflatable membrane structure is based on continuous inflation indoors, which can generate certain Pressure difference (generally between 10 mm and 30 mm water column), the pressure difference between indoor and outdoor makes the roof Membrane cloth Under a certain upward buoyancy, a large span is achieved. The tensioned structure is supported by columns and steel frames or tensioned by steel cables, and its shape is very beautiful and flexible
