In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments.

As shown in fig. 1 to 4, the present invention discloses a thin plate narrow section box shear wall, which includes two sets of box columns 20, at least two sets of wall segments 10, and at least one column top sealing plate 30, wherein three sets of wall segments 10 are taken as an example for description. The three groups of wall body sections 10 are sequentially welded and fixed between the two groups of box-shaped columns 20 to form a wall body.

The wall segment 10 includes a first wing plate 11, a second wing plate 12, a first web 13, a second web 14, and a plurality of first stiffener plates 15 for preventing welding deformation. First pterygoid lamina 11 and the mutual parallel arrangement of second pterygoid lamina 12, first web 13 and second web 14 are parallel arrangement each other and weld side by side between first pterygoid lamina 11 and second pterygoid lamina 12 equally, a set of relative border on first stiffener 15 respectively with first pterygoid lamina 11 and the welding of second pterygoid lamina 12, the border of first stiffener 15 still with first web 13 or the welding of second web 14, first pterygoid lamina 11 like this, second pterygoid lamina 12, first web 13, second web 14 and first stiffener 15 form the reinforcing system that supports each other, guarantee the shear strength of the wall body of final formation. In order to ensure that the first web plate 13 and the second web plate 14 can be welded completely, welding hand holes 17 are formed in the edges of the first wing plate 11 and/or the second wing plate 12 in the length direction, one side, located inside the box body, of the first web plate 13 and the second web plate 14 can be welded with the heel through the welding hand holes 17, especially when the upper-end shear wall and the lower-end shear wall are connected, the welding inside the box body of the two shear walls can be completed through the welding hand holes 17, and therefore the connection between the two shear walls is more reliable. A plurality of first concrete through holes 16 are formed in the first web plate 13 and the second web plate 14 at intervals along the length direction, and the first concrete through holes 16 are arranged so that concrete can be connected without being broken when grouting. The first concrete through hole 16 may be a rectangular hole, and the first concrete through hole 16 may also be used as a welding hand hole, so that the welding of the inner sides of the first web plate 13 and the second web plate 14 is easier.
