[0023] The present invention describes a metal frame assembly for floor decking, such as... Figures 1-4 As shown, it includes an upper chord 1, which is a steel pipe, structural steel or other non-reinforced structure. Both sides of the upper chord 1 are connected to web reinforcement 2, and each web reinforcement 2 is made by continuously bending a steel bar.

[0024] As shown in Figure 3 , the upper chord 1 can be located between the two side webs 2, and the webs 2 are welded and fixed to the arc edges on both sides of the upper chord. As shown in Figure 16 , the upper chord 1 is located at the top of the two side webs 2, and the webs 2 are welded and fixed to the two sides of the bottom of the upper chord 1.

[0025] The lower part of the web 2 is bent outward to the horizontal to form a horizontal bend 3, which can replace the stable connection between the traditional lower chord and the bottom plate. Compared with the fixed connection of the lower chord at the bottom of the web 2, the horizontal bend 3 is directly bent at the bottom of the web 2, which is simple to manufacture and has better integrity, and the connection between the web 2 and the bottom plate is more stable, and the overall structure has better rigidity.

[0026] The side web 4 is connected to the middle and lower parts of the web 2 on the outside, and the length direction of the side web 4 is parallel to the length direction of the upper chord 1. The arrangement of the side web 4 can enhance the connection strength between the web 2 and the cast-in-place layer on the bottom plate, improve the strength of the overall structure, and meet the arrangement spacing requirements of the steel structure in the floor support plate. It can not only be combined with the decorative plate type bottom plate, but also be used for floor support plates with protective layer requirements.

[0027] Further, as shown in Figure 5 and Figure 6 , the upper chord 1 is a steel pipe, and the cross section of the steel pipe is circular, oblong or elliptical or other shapes. As shown in Figures 7-10 , the upper chord 1 is a profile steel, and the cross section of the profile steel is trapezoidal, rectangular, H-shaped or grooved or other polygonal shapes. The upper chord 1 can also be an angle steel or other structures. The use of steel pipes, profile steels or other non-steel structures for the upper chord 1 can not only improve the strength of the structure, but also save the amount of steel, and has better economic efficiency and stronger strength, rigidity and overall carrying capacity.

[0028] Further, the upper chord 1 is a profile steel with a trapezoidal cross section, and the trapezoidal cross section is an isosceles trapezoid. The slope of the two sides of the isosceles trapezoid is consistent with the slope of the web 2, and the web 2 is in surface contact and welded to the side of the isosceles trapezoid. The connection between the web 2 and the upper chord 1 can be more tightly connected.

[0029] The technical scheme of the present application is not limited to the scope of the embodiments described in the present application. The technical content not described in detail in the present application is known technology.
