Introduction of steel structure toll booth space frames construction - design and construction of the space truss and toll station space frames construction. High structural form of steel strength. With the construction model of the space truss, TINTA also provides space truss accessories such as cone head, cage, bar bolt, hexagon bolt, iron ball, steel ball space truss for the gymnasium. or construction of toll station space frame.

In the design and construction of the toll booth space frames of steel structure technology, TINTA is a pioneer for more than 20 years specializing in the construction of toll station space frames. Today, in addition to the construction of the space frames, TINTA has provided space frame accessories for construction companies to construct the toll booth space frames by themselves to maximize costs for the investor.

1. Construction structure of toll station space frames and steel pipe. Also known as steel pipe space truss structure, pipe truss, pipe structure, is divided into a plane or space truss system.

The difference in the construction of the toll booth space frames compared to the common rafter is the connection of the nodes. The space truss structure uses screwed ball buttons or hollow balls, while the fixed welded pipe truss structure only uses steel pipes. Round steel pipes or square steel pipes, welded directly at the intersections at bridge nodes.

Steel pipe toll station space frame construction structure has the advantage of simple button form, concise and generous form. At the same time, due to the use of weld intersecting at the cone end with bolts, cage, it is also beneficial for rust prevention and cleaning and maintenance. However, intersecting welding has certain requirements on processing technology and equipment, so the structure of the steel pipe truss's space gantry construction has some limitations.

The design and construction of the toll station space frames of the intersections must be designed similar to the outer diameter of steel pipes. For bars with different bearing capacity, the same outer diameter of steel pipe and different wall thickness is often used. The wall thickness of the pipe should not change too much, otherwise, the number of joints between steel pipes is too large. Therefore, it is not possible to promote the maximum strength of the material to increase the amount of steel used. This is one of the reasons that the construction of the toll booth space truss with steel pipe truss structure often uses more steel than the herringbone structure.

2) Toll station space rig construction and intersection are complicated, the groove on the intersection is changed, it is difficult to cut by hand, so the machine requirement is very high.

3) Steel pipe truss space gantry construction structures are welds, need to control the amount of welding shrinkage, require high welding quality, and are welded on site, and the workload is large.

TINTA Joint Stock Company not only constructs but also produces and sells accessories.

The construction process of toll station space frames. With the development of laser cutting technology and multi-thickness numerical control over cutting thickness, a number of difficulties have been overcome in the process of fabricating toll station space gantry and steel pipe truss structure. Currently, some domestic enterprises contact TINTA to buy space frame accessories. Tinta has many years of design and installation of space truss with this technology, so it is possible to advise the use of intersecting point pipe truss structure in real works.

Structure of the space truss and construction of the steel tubular toll booth space truss should apply the form of vertical triangular cross-section space truss. That is, it consists of a layer of the upper truss, a layer of the lower truss, and the crossbar structures. Connecting these layers of space truss is also called the main pipe and the crossbar is called the branch duct.

The diameter of the main pipe is relatively thick, also connected together to facilitate cross welding of branch pipes. It is advisable to choose the layout when designing and constructing toll booth space with reasonable width and height. The weld seams connect the tubes and the cone end, so the design of the wing details as far as possible. Toll station space rig constructions or coal storage structures may be equipped with a number of three-dimensional pipe trusses. Crossbars and tie bars should be placed between each pipe truss.

The toll station space truss construction model used in the calculation and analysis of the steel pipe space truss structure is mainly related to the stiffness of the interconnection node. According to the bending moment of the rod end and the stiffness of the ball joint, there are three analytical models: ①Rating bar energy where all the components have ball knots; All components are considered to be bridged. As for hardness, the parts are considered according to the beam factor; ③ Assume that the main steel pipe truss bars are a tightly connected herringbone beam, branch duct, and main pipe have hinges and only axial load-bearing branch duct.

For the construction of the space gantry of the steel pipe truss structure, special pipe truss nodes are required. The pipe truss node described here does not use a truss plate, hollow ball or bolts, but rather refers to steel pipes (round steel or square steel pipes) that directly intersect with welded steel pipes at intersections. each other and there are only two main tubes on the same shaft. Through the construction of the toll booth space rig, the remaining bars (ie branch pipes) are welded directly to the outer surface of the pier (ie the main pipe) after being processed by the final junction; non-penetrating bars have a certain gap at the node (gap-type node), or part of it Overlap (junction type button).

The form of toll booth space frame construction of the intersections is related to the number of connected bars. When the cross truss bars and the flat bars are in the same plane, it is a single plane node and when the cross truss bars and the zero bar are in the same plane, it is a point to note the load force of the plane. A specific outer layer of multiple plane nodes is shown in the toll booth space rig construction.

Cutting the junction in tollgate space frames construction used to be considered a more difficult manufacturing process, as the number, angle, and size of the steel pipes intersect making the shape of the junction. differential and more difficult groove machining in a space rig. structure. But with the development of multi-dimensional CNC cutting technology, these difficulties have been overcome. Currently, some domestic enterprises have been equipped with this technology, including TINTA, which is always the pioneer in the construction of toll station space, so a similar steel pipe truss structure has good prospects for application in large-span structures.
