Description

Technical Field

[0001] The utility model relates to the technical field of folding construction equipment for lattice shell units, in particular to a movable hinge device for folding and unfolding a lattice shell structure. Background Art

[0002] At present, lattice shell structures are used more and more. For large-space lattice shell structures, the commonly used methods are high-altitude bulk method, strip and block installation method, structural sliding method, overall lifting, and jacking method. Among them, overall lifting and overall jacking construction methods are more widely used.

[0003] For lattice shell structures with large spans and operating in confined spaces, general lifting or jacking methods cannot meet the construction requirements, and high-altitude bulk construction consumes more materials and manpower. Therefore, the "folding and unfolding method" of lattice shell construction was born. The core of lattice shell folding is the movement of the mechanism, and the key to the movement of the mechanism is the structure of the movable hinge.

[0004] However, the movable hinge setting is not yet mature, and there is no movable hinge device on the market that can fold the lattice shell unit. Therefore, there is an urgent need for a movable hinge that can be used for folding and unfolding overall construction. Utility Model Content

[0006] The technical solution is that it comprises a node plate connected by an axle pin, a connecting steel plate is arranged on the top of the node plate, and a rod member is arranged on the top of the connecting steel plate;

[0007] The shaft pins include a main shaft pin and a secondary shaft pin;

[0008] The main shaft pin is used for the hinge point to rotate, and the secondary shaft pin is used for fixing the rotating shaft.

[0009] The node plates are arranged in three pieces, one of which is located at one end of the main shaft pin and the secondary shaft pin, and the other two node plates are located at the other end of the main shaft pin and the secondary shaft pin.

[0010] The main shaft pin and the secondary shaft pin are both made of high-strength bolts.

[0011] The two node plates located on the same side of the main shaft pin and the secondary shaft pin are respectively arranged on the inner and outer sides of the single node plate on the other side.

[0012] The connecting steel plates are provided in two pieces, and the two connecting steel plates are respectively cross-welded with the node plates;

[0013] One of the connecting steel plates is arranged on the single node plate on one side, and the other of the connecting steel plates is arranged on the two node plates on the other side.

[0014] A gap is provided between the shaft pin and the node plate, and lubricating oil is applied to the gap to ensure free rotation of the node.

[0015] The beneficial effects of the technical solution provided by the embodiment of the utility model are as follows: the solution provides a movable hinge device for folding and unfolding a lattice shell structure, which can be used for folding and unfolding overall construction. The core is to use the movable hinge node to realize the rotation of the unit when the lattice shell structure is folded and unfolded at high altitude;

[0016] It is mainly composed of two pins, three node plates, and two connecting steel plates. The pin position can be assembled and disassembled immediately, and can be used in a turnover manner with high flexibility. Both pins use high-strength bolts. The main pin is responsible for the rotation of the hinge point, and the secondary pin is responsible for fixing the shaft, so that the component can be fixed in time after reaching the required angle. The three node plates are connected together by high-strength bolts and can rotate 180 degrees with a large rotation angle. The two connecting steel plates are cross-welded with the node plates respectively, and the connecting steel plates can adjust their directions in real time according to the angle of the component.

[0017] This solution has a simple structure and can be directly assembled and adjusted on site. The assembly is simple, the materials used are energy-saving, can be used in rotation, and the materials are recyclable. The entire hinge node structure conforms to the mechanical model of hinged connection, the force is clear and direct, the shape is beautiful and generous, and it truly turns the folding and rotation of the lattice shell structure from theory to practice, and it is highly practical. It can be applied to the connection and installation of rod components at various angles and directions; the number and area of ​​connecting steel plates can be adjusted in real time according to the number of rod components; the angle of the unfolding unit can be quickly fixed; it has a wide range of applications and can realize the folding of single-layer and double-layer lattice shell structures and special-shaped lattice shell structures; compared with traditional hinges, there is no need to use cables, and the folding unit can be fixed by axle pins.
