Grout sleeve for steel bar connection and machining process of grout sleeve
The invention relates to the technical field of steel bar sleeve grouting and discloses a grout sleeve for steel bar connection. The grout sleeve comprises an on-site assembling end and a prefabricated mounting end which are sequentially arranged in the grout flowing direction, wherein the on-site assembling end is provided with a feeding through hole, and the prefabricated mounting end is provided with a discharging through hole; a feeding conduit is fixed to the feeding through hole, and a discharging conduit is fixed to the discharging through hole; two wavy bosses are arranged on the innerwall of a grout sleeve body and are distributed at the two sides of a longitudinal section of the grout sleeve body in spatial symmetry along a longitudinal line; and upper groove lines are arrangedabove a transverse section of the outer wall of the grout sleeve body, lower groove lines are arranged below the transverse section of the outer wall of the grout sleeve body, and heat exchange circulating pipelines are tightly attached to the upper groove lines and the lower groove lines respectively. According to the grout sleeve, bubbles introduced in the grout construction process can be smoothly discharged, the universality of stress of a grout connecting joint of the steel bar sleeve is improved, the machining difficulty of the grout sleeve is lowered, the process is simple, the universality is high, and the requirement for construction in winter and summer can be met.
本发明涉及钢筋套筒灌浆技术领域，且公开了一种钢筋连接用灌浆套筒，按灌浆流动方向依次包括现场装配端和预制安装端；现场装配端设有进浆通孔，预制安装端设有出浆通孔；进浆通孔处固定有进浆导管，出浆通孔处固定有出浆导管，灌浆套筒内壁设置有波形凸台，波形凸台为两个，两个波形凸台分布于灌浆套筒纵向截面两侧且沿纵线空间对称分布；灌浆套筒外壁横向截面以上设置有上凹槽纹路，灌浆套筒外壁横向截面以下设置有下凹槽纹路，上凹槽纹路和下凹槽纹路上均密切贴合有热交换循环管路。本发明有利于使灌浆施工过程中引入的气泡顺利排出并提高钢筋套筒灌浆连接接头受力的均匀性，降低了灌浆套筒加工难度，工艺简单，通用性强，能满足冬夏施工要求。
