[0027] The existing concrete structure building slab will be provided with a concrete structure beam 100 to improve the structural strength of each layer, wherein the concrete structure beam 100 comprises a cross beam 120 arranged in the horizontal direction.

[0030] Compared with the prior art, the present application adopts a steel structure, which can be prefabricated in advance, is convenient to process, does not need to be poured with concrete, and does not need to reserve a hole in advance. The steel structure supporting assembly serves as both a permanent supporting structure of the curtain wall 200 and a temporary support during the construction of a light partition wall, does not need to additionally invest in a formwork and a support frame, has low cost and short construction period; the steel structure is used as a transfer supporting structure of the curtain wall 200 due to its large strength and applicability to large-span supporting structures, reduces the connection nodes with the main structure of the concrete structure beam 100, and reduces the influence on the main structure of the concrete structure beam 100; and the present application can be used for the installation of curtain walls 200 of various angles, and the shape of the first steel member can be adjusted according to the requirements to meet the installation requirements at the corner of the lintel, effectively reducing the construction difficulty and improving the construction accuracy.

[0031] The fireproof layer 330 comprises a gypsum board and fireproof rock wool, the side of the first steel member is sealed with the gypsum board, and the fireproof rock wool is laid between the gypsum board and the first steel member to achieve the purposes of heat insulation and fireproofing.

[0032] In some embodiments, as Figure 1 and Figure 2As shown, the concrete structure beam 100 further comprises two load-bearing columns 110, which respectively support the ends of the cross beam 120, and the ends of the first steel member extend to be connected with the load-bearing columns 110. After the first steel member is hung below the cross beam 120, the ends of the first steel member are fixed with the load-bearing columns 110 to make the first steel member fixed firmly, and the first steel member is not easy to loosen and fall after bearing the weight of the load-bearing curtain wall 200.

[0033] In some specific embodiments, the first steel member comprises a plurality of first steel pieces 310 and second steel pieces 320, the first steel pieces 310 are arranged at intervals along the length direction of the cross beam 120, the first steel pieces 310 are hung in the vertical direction on the cross beam 120, the second steel pieces 320 are arranged in the horizontal direction, the adjacent two first steel pieces 310 are connected through the second steel pieces 320, and the first steel piece 310 close to the load-bearing column 110 is connected with the load-bearing column 110 through the second steel piece 320.

[0034] Specifically, as shown in the figure, Figure 2 As shown, the two sides of each first steel piece 310 are provided with the second steel pieces 320, one end of the vertically arranged first steel piece 310 is fixedly connected with the cross beam 120, and the side edge of the first steel piece 310 is connected with the load-bearing column 110 or another first steel piece through the horizontally arranged second steel piece 320, so as to improve the bending resistance of the first steel piece 310. The combined connection of the first steel piece 310 and the second steel piece 320 makes the structural design of the first steel member simple, light in weight, and also has strong load capacity.

[0035] In some embodiments, the ends of the plurality of first steel pieces 310 away from the cross beam 120 are connected through the same second steel piece 320, and the same end of all the first steel pieces 310 is connected through one second steel piece 320, and after the two ends of the second steel piece 320 are connected with the load-bearing column 110, the structural rigidity of the entire first steel member is effectively strengthened.
