The invention discloses a concrete-filled steel tube shear wall with concrete wrapped around side faces. The concrete-filled steel tube shear wall comprises a wall limb steel tube cavity containing atleast one closed cavity and formed by welding limb end plates, a corner steel tube and a plurality pieces of wall limb profile steel, the outward extending lengths of the limb end plates relative tothe two sides of the wall limb steel tube cavity each are not less than 20mm, core concrete fills the wall limb steel tube cavity, wrapping concrete is arranged on the outer side of the wall limb steel tube cavity, the thickness of the wrapping concrete is the same as the outward extending length of each limb end plate, holes for allowing the concrete to pass through are formed in the side faces of the closed cavities, needing to be filled with the core concrete, in the wall limb steel tube cavity, wherein the holes are distributed in an array mode or a quincunx mode, and the core concrete inside the wall limb steel tube cavity and the wrapping concrete on the outer side of the wall limb steel tube cavity are connected into a whole through the holes. The concrete inside and outside the steel tube is poured at the same time and connected into a whole through the holes, the wrapping concrete is effectively prevented from falling off in the using stage, the concrete outside the tube can solve the problems about corrosion and fire resistance of steel plates on the two sides at the same time, the concrete-filled steel tube shear wall is suitable for prefabrication production, and the construction cost is low.
本发明公开了一种侧面裹覆混凝土的钢管混凝土剪力墙，包括由肢端板、转角钢管和若干墙肢型钢焊接组成的不少于一个封闭空腔的墙肢钢管腔，肢端板相对于墙肢钢管腔的两侧外伸长度各不小于20mm，墙肢钢管腔内部填充核心混凝土，墙肢钢管腔外侧设有裹覆混凝土，裹覆混凝土的厚度与肢端板外伸长度相同，墙肢钢管腔中需填充核心混凝土的封闭空腔的侧面设有供混凝土通过孔洞，孔洞呈阵列式或梅花状分布，墙肢钢管腔内部的核心混凝土和外侧的裹覆混凝土通过孔洞连接为整体。钢管内外的混凝土同时浇筑，通过孔洞连接形成整体，有效防止裹覆混凝土在使用阶段的脱落，管外混凝土同时能够解决两侧钢板的腐蚀和抗火问题，适合预制化生产，施工成本低。
