Detailed ways

Specific implementations of the present utility model will be described below, and it should be pointed out that in the specific description process of these implementations, in order to describe briefly and concisely, it is impossible for this specification to describe all the features of the actual implementations in detail. .

Below in conjunction with above-mentioned accompanying drawing, the utility model embodiment is described in detail again. the

As shown in Figure 1, the utility model is a curtain wall support system based on large-span horizontal fish-belly steel trusses. The fish-belly steel trusses 1 are arranged at a certain distance, and the galvanized steel columns 00 of the curtain wall 0 are hinged with the fish-belly steel trusses 1.

Furthermore, as shown in the figure, the fish-belly steel truss 1 is arranged with three tie rod structures 11 in the orthogonal direction outside the plane. When the span is large, the free length of the rods outside the plane is too large to cause instability. Possibly, the horizontal fishbelly truss structure adopts three tie rod structures 11 arranged in an out-of-plane orthogonal direction as a stable structure.

Arrange 5 fish-belly steel trusses 1 with a span of 30m every 6500mm above the curtain wall 0. The galvanized steel columns of the front lobby curtain wall 0 are hinged to the fish-belly steel truss 1, the self-weight load of the curtain wall 0 acts on the ground structure from top to bottom, and the wind load of the curtain wall 0 acts on the horizontal fish-belly truss.

Referring to Figure 2 and Figure 3, the galvanized steel column 00 has a steel plate connector 2, and the fish-belly steel truss 1 has a steel plate support 12, the steel plate support 12 is mainly composed of two steel plates, and the steel plate connector 2 is inserted between the two steel plates between and fixed. Specifically, the insertion distance of the steel plate connector 2 between two steel plates is 15 mm adjustable (±15 mm).

During the specific construction, continue to refer to Fig. 2 and Fig. 3, first insert the steel plate connector 2 of the curtain wall steel column 00 between the two steel plates of the steel plate support 12 on the fish-belly steel truss 1, and then four Adjust the direction of the relative position of the steel plate connector 2 (steel column 00) and the steel plate support 12 (fish-belly steel truss 1). The steel plate connectors 2 of the steel column are welded together, the weld seam is polished smooth and the exterior surface is treated (fluorocarbon spraying in this example), this step makes the galvanized steel column 00 of the front lobby curtain wall and the fish-belly steel truss 1 is hinged, the self-weight load of the curtain wall 0 acts on the ground structure from top to bottom, and the wind load of the curtain wall 0 acts on the horizontal fish-belly truss; finally, the aluminum alloy decoration of the steel column 00 and the curtain wall glass and other components are installed to complete the entire front lobby curtain wall 0 installation work.

During the implementation process, the steel plate support 12 on the fish-belly steel truss 1 has been welded and polished in the factory in advance, and must be positioned accurately. This link is related to whether the positioning of the curtain wall steel column 00 in the left and right directions meets the engineering curtain wall division quality requirements; In addition, when the steel column is installed on the construction site, the relative relationship with the fish-bellied steel truss 1 must be accurately positioned, and the on-site measurement work is difficult and requires high precision; when the steel gasket is welded to the steel plate connector 2 of the steel column 00, care must be taken to prevent The steel plate is overheated and deformed.

The numerical values in this embodiment are only set to meet specific engineering requirements, without any limiting meaning. Although the present utility model has been described in conjunction with specific embodiments, those skilled in the art can understand that many modifications and variations can be made to the present utility model. It is therefore to be realized that the appended claims are intended to cover all such modifications and variations as are within the true spirit and scope of the present invention.
