The invention discloses a full-grouting sleeve for steel bar connection of an assembly-type building. The sleeve is characterized by comprising a rectangular pipe orifice (10), a first reducer pipe body (3), a second reducer pipe body (7), a round pipe orifice (13), a transition pipe body used for communicating between the first reducer pipe body and the second reducer pipe body, a pulp dischargehole (11) and a grouting hole (12), wherein axial cross sections of two ends of the transition pipe body are square; the upper end of the transition pipe body gradually changes to the rectangular pipeorifice through transition and shrinking of the first reducer pipe body; and the lower end gradually changes to the round pipe orifice through transition and shrinking of the second reducer pipe body. The sleeve disclosed by the invention has the beneficial effects that the structure is simple; application cost is low; the length of the full-grouting sleeve and cross sections of corresponding beam columns can be greatly reduced; and tensile strength of the full-grouting sleeve is further enhanced, and application cost of the assembly-type building is further reduced.
本发明公开了一种装配式建筑钢筋连接用全灌浆套筒，其特征在于，包括长方形管口（10）、第一变径管体（3）、第二变径管体（7）、圆形管口（13）、用于连通第一变径管体和第二变径管体的过渡管体、排浆口（11）和灌浆口（12），所述过渡管体两端的轴截面均为方形，其上端通过第一变径管体过渡缩小渐变成长方形管口，下端通过第二变径管体过渡缩小渐变成圆形管口。本发明结构简单，应用成本低，可大大减少全灌浆套筒的长度和相应梁柱的截面，进一步增强了全灌浆套筒的抗拉强度和减少了装配式建筑的应用成本。
