A method of making folding square truss

2021-1-18
Brief Introduction:

Various types of trusses currently appearing on the market mainly include truss members and connectors. The truss members are provided with ribs, and multiple truss members are connected to each other through the connectors to form a truss structure.

 

The utility model relates to a folding frame, in particular to a foldable quadrangular truss.


Background technique:


Various types of trusses currently appearing on the market mainly include truss members and connectors. The truss members are provided with ribs, and multiple truss members are connected to each other through the connectors to form a truss structure. This kind of truss only needs to assemble the connecting piece and the truss rod when it needs to be assembled. When it needs to be transferred and transported, the connecting piece and the truss rod need to be separated and packaged, and then re-assembled when it reaches another position. The time spent on assembly and disassembly in the process is relatively long, which is very time-consuming.

Detailed ways


In order to make the technical means, creative features, objectives and effects of the utility model easy to understand, the following describes the utility model further in conjunction with specific implementations.


As shown in Figure 1-3, a foldable quadrangular truss includes a No. 1 quadrangular truss 8, a No. 2 quadrangular truss 9 and a folding head 4. The top side of the No. 1 quadrangular truss 8 passes through a hinge The aluminum 2 is connected to the No. 2 quadrangular truss 9. Both sides of the bottom of the No. 1 quadrangular truss 8 and the No. 2 quadrangular truss 9 are welded with folding female socket aluminum 3, and one side of the folding female socket aluminum 3 passes through a folding H-shaped joint The male 5 is connected to the aluminum round pipe 6, the folding head 4 is installed between the aluminum round pipes 6 through fixing bolts, and the two ends of the No. 1 square truss 8 and the No. 2 square truss 9 are provided with connecting sleeves 1 at both ends.


Wherein, the surface of the No. 1 quadrangular truss 8, the No. 2 quadrangular truss 9 and the aluminum round pipe 6 are all provided with a fireproof water glass layer 10, and the surface of the fireproof water glass layer 10 is provided with an anticorrosive epoxy resin layer 12. A high temperature resistant baking varnish layer 11 is provided between the fireproof sodium silicate layer 10 and the anticorrosive epoxy resin layer 12.


Wherein, the first quadrangular truss 8 and the second quadrangular truss 9 are both welded with reinforcing rods 7. The reinforcing rod 7 can increase the structural strength of the No. 1 quadrangular truss 8 and the No. 2 quadrangular truss 9 so as to enhance the overall structural strength of the quadrangular truss.


Wherein, the hinge aluminum 2 is provided in several groups.


It should be noted that the utility model is a foldable quadrangular truss. When working, the folding head 4 and the hinge aluminum 2 work together to complete the folding of the quadrangular truss during packaging and transportation (the folding head is bent at 4 places). In order to reduce the area occupied) or the unfolding of the square truss in use (the 4 points of the folding head are straightened to make the No. 1 square truss 8 and the No. 2 square truss 90 cross-shaped), the No. 1 square truss 8 and No. 4 The installation of the square truss 9 and the aluminum round pipe 6 surface fireproof water glass layer 10, anti-corrosion epoxy resin layer 12 and high temperature baking varnish layer 11 can enhance the fire resistance, corrosion resistance and high temperature resistance of the square truss and extend the square truss Service life.
