Semi-grouting sleeve assembly for fabricated building and construction method thereof
The invention discloses a semi-grouting sleeve assembly for prefabricated building. The semi-grouting sleeve assembly comprises a first steel bar provided with a first external thread, a second steelbar provided with a second external thread, an integrated nut bolt, a straight thread sleeve provided with a grout discharging hole, a semi-grouting sleeve and a square nut. The semi-grouting sleeve comprises a rectangular pipe, a square-round reducer pipe, a round pipe, an outer-round inner-square pipe and a grouting hole formed in the square-round reducer pipe; one end of the rectangular pipe istransitionally enlarged and gradually changed to one end of the round pipe through the square-round reducer pipe, the outer diameter of the round pipe is the same as that of the outer-round inner-square pipe, and fourth external threads are arranged on the outer surfaces of the round pipe and the outer-round inner-square pipe; and a rectangular hole allowing the first steel bar to penetrate through and allowing the square nut not to penetrate through is formed in the outer-round inner-square pipe, and first internal threads matched with the first external threads and third external threads are formed in the straight thread sleeve. The semi-grouting sleeve assembly is simple in structure and low in application cost, and the overall quality of the semi-grouting sleeve assembly can be guaranteed when the sleeve is not fully grouted.
本发明公开了一种装配式建筑用半灌浆套筒组件，包括设有第一外螺纹的第一钢筋、设有第二外螺纹的第二钢筋、一体式螺母螺栓、设有排浆孔的直螺纹套筒、半灌浆套筒和方形螺母，所述半灌浆套筒包括长方形管、方圆变径管、圆形管、外圆内方管和设置在方圆变径管上的灌浆孔，所述长方形管的一端通过方圆变径管过渡扩大渐变至圆形管的一端，所述圆形管和外圆内方管的外径相同，其外表面均设有第四外螺纹，所述外圆内方管设有用于第一钢筋穿过且方形螺母不能穿过的长方形孔，所述直螺纹套筒设有与所述第一外螺纹和第三外螺纹相匹配的第一内螺纹。本发明结构简单，应用成本低，可使套筒在灌浆不满时还能保证半灌浆套筒组件的整体质量。
