[0029] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] like Figure 1-3 A light steel shear wall is shown, comprising a top beam 1, a bottom beam 2, a wall frame column 3 and a shear wall steel end column 4, wherein the top beam 1 and the bottom beam 2 are arranged in parallel up and down, and two shear wall steel end columns 4 are respectively fixed to the two ends of the top beam 1 and the bottom beam 2 to form a rectangle or a square; the two ends of a plurality of wall frame columns 3 are respectively fixed to the top beam 1 and the bottom beam 2; and galvanized steel plates or aluminum-zinc-coated steel plates 5 are also included, wherein the galvanized steel plates or aluminum-zinc-coated steel plates 5 are arranged simultaneously on at least one or both sides of the front side or the rear side of the wall, and are respectively fixedly connected to the top beam 1, the bottom beam 2, the wall frame column 3 and the shear wall steel end column 4.

[0031] Among them, the cross-sections of the top beam 1 and the bottom beam 2 are both U-shaped or C-shaped, the top end of the shear wall steel end column 4 is tightly pressed against the web of the top beam 1 and fixedly connected to the flange of the top beam 1; the bottom end of the shear wall steel end column 4 is tightly pressed against the web of the bottom beam 2 and fixedly connected to the flange of the bottom beam 2; the shear wall steel end column 4 is a combined end column or a hot-steel end column composed of a single cold-bent thin-walled steel end column or multiple cold-bent thin-walled steel columns; the top and bottom flanges of the shear wall steel end column 4 are respectively fixedly connected to the flange of the top beam 1 and the flange of the bottom beam 2.

[0032] The top end of the wall frame column 3 is pressed against the web of the top beam 1 and fixedly connected to the flange of the top beam 1; the bottom end of the wall frame column 3 is pressed against the web of the bottom beam 2 and fixedly connected to the flange of the bottom beam 2; the cross-section of the wall frame column 3 is C-shaped, and the flanges of the top and bottom ends of the wall frame column 3 are fixedly connected to the flange of the top beam 1 and the flange of the bottom beam 2 respectively.

[0033] The fixing methods include but are not limited to screws, bolts, rivets or welding.

[0034] In this embodiment, a U-shaped (or C-shaped) top beam 1, a U-shaped (or C-shaped) bottom beam 2, a plurality of C-shaped wall frame columns 3, two shear wall steel end columns 4 (cold-bent thin-walled steel end columns or hot-steel end columns), and a galvanized steel plate or an aluminum-zinc-coated steel plate 5 together constitute a steel frame. When the steel frame is subjected to lateral loads, the wall frame columns 3 and the galvanized steel plate or the aluminum-zinc-coated steel plate 5 in the inner cavity of the steel frame provide lateral stiffness for the steel frame, so that the steel frame will not tilt laterally when subjected to lateral loads, thereby improving the structural safety of the building.

[0035] like Figure 4-7As shown, a connection structure between a light steel shear wall and a foundation includes at least the light steel shear wall fixed on a concrete foundation 7, an iron embedded part 8 is preset on the concrete foundation 7, the shear wall steel end column 4 corresponds to the iron embedded part 8 and the two are fixed by an iron connecting part 9, and the bottom beam 2 is fixed to the concrete foundation 7 by bolts 10.

[0036] The light steel shear wall is installed on the concrete foundation 11, and an iron embedded part 8 is pre-set on the concrete foundation. The embedded position of the iron embedded part 8 is at the shear wall steel end column 4. When the light steel shear wall is installed on the concrete foundation 11, the shear wall steel end column 4 is on the upper surface of the iron embedded part 8, and the shear wall steel end column 4 is welded to the iron embedded part 8 through the iron connector 9 (if there is no embedded part, the anti-pull connector can be used to effectively connect with the foundation through bolts). The bottom beam 2 is effectively connected to the foundation through bolts 10 (or chemical anchor bolts, etc.).

[0037] like Figure 5 It is a top view: the iron connector 9 is arranged on the front and rear sides of the shear wall steel end column 4 and is effectively welded to the shear wall steel end column 4, and the iron connector 9 is effectively welded to the iron embedded part 8. When there is no space for installing the iron connector 9 on the left and right sides of the shear wall steel end column 4, it can be installed on the remaining two sides, as shown in 9A.

[0038] The iron connecting piece 9 is only a schematic diagram in the figure, and the shape is not the main one. Any parts that can form a fixed connection should be within the protection scope.

[0039] like Figure 8-11 The connection structure between a light steel shear wall and a floor shown in the figure comprises at least two light steel shear walls, wherein the upper light steel shear wall Q2 and the lower light steel shear wall Q1 are respectively located above and below the floor and aligned. The upper light steel shear wall Q2 comprises an upper wall top beam 111, an upper wall bottom beam 112, an upper wall frame column 113 and an upper shear wall steel end column 114, and the lower light steel shear wall Q1 comprises a lower wall top beam 121, a lower wall bottom beam 122, a lower wall frame column 123 and a lower shear wall steel end column 124, and the structures are the same, using the light steel shear wall structure, and are assembled from top to bottom.

[0041] Please refer to Figure 8 : The upper shear wall steel end column 114 and the lower shear wall steel end column 124 are aligned and placed, and the two are effectively fixedly connected by screws (or bolts, rivets, welding, etc.) through the connecting plate 6. When installing the connecting plate 6, it is necessary to groove the upper wall bottom beam 112 and the lower wall top beam 121 to facilitate the installation of the connecting plate 6.

[0042] For the sake of simplicity, only one end column at both ends of the shear wall is used to explain in detail how they are connected to each other.

The upper shear wall steel end column 114 and the lower shear wall steel end column 124 are aligned and placed, and the front and rear sides between the two are effectively connected by screws (or bolts, rivets, welding, etc.) through the connecting plate 6. When installing the connecting plate 6, it is necessary to make grooves on the upper wall bottom beam 112 and the lower wall top beam 121 to facilitate the installation of the connecting plate 6. When there is no space for installing the connecting plate 6 at the groove, it can be installed on the remaining two sides, as shown in 6A.

[0045] The web of the upper wall bottom beam 112 and the web of the lower wall top beam 121 are effectively connected by screws 10 (or bolts, rivets, welding, etc.).

[0046] like Fig.12 The figure is an overall diagram of the connection structure between the light steel shear wall, the floors and the foundation. The lower light steel shear wall Q1 is fixed on the concrete foundation 7, and the upper light steel shear wall Q2 is installed on the lower light steel shear wall Q1 to form upper and lower floors.

[0047] The setting of the light steel shear wall and its connection method between the upper and lower floors and the foundation are reasonably designed in structure. The shear wall steel end columns (cold-bent thin-walled steel end columns or hot-steel end columns), U-shaped (or C-shaped) top beams, U-shaped (or C-shaped) bottom beams and C-shaped cold-bent thin-walled steel wall frame columns and the galvanized or galvanized steel plates on both sides (or one side) of the wall form a lateral force resistance system, which provides effective lateral stiffness for the cold-bent thin-walled steel frame structure and can effectively improve the earthquake and wind resistance of the cold-bent thin-walled steel frame structure; the connection method of the shear wall between the upper and lower floors and with the foundation can enhance the pull-out resistance, thereby ensuring the structural safety of the building.
