Grouting joint bar compaction grouting sleeve precast concrete column and construction method
The invention discloses a grouting joint bar compaction grouting sleeve prefabricated concrete column and a construction method, the grouting joint bar compaction grouting sleeve prefabricated concrete column comprises a plurality of sections of prefabricated concrete columns which are connected up and down, the top of each prefabricated concrete column is provided with a circular steel pipe sleeve and a grouting sleeve, and the side surface of each prefabricated concrete column is provided with a grouting port and a grout outlet which are communicated with the inner cavity of each grouting sleeve; round steel pipe concrete shear keys and connecting steel bars protrude out of the bottom of the prefabricated concrete column, when all the sections of the prefabricated concrete column are spliced, the round steel pipe concrete shear keys are inserted into the round steel pipe sleeves, the connecting steel bars are inserted into the grouting sleeves, and the grouting sleeves and the round steel pipe sleeves are filled with high-strength grouting materials. According to the invention, grouting materials in all the sleeves can be ensured to be fully and compactly filled, and complicated sub-warehouse and pressure grouting links are not required to be carried out after steel bars are inserted into the test piece sleeves, so that the construction difficulty and the quality risk of pressure grouting in a traditional mode are greatly reduced, the defects of holes and the like caused by non-compact grouting are avoided, and safe and reliable force transmission at a connection position is ensured.
本发明公开了一种灌浆插筋挤密灌浆套筒预制混凝土柱及施工方法，包括多段上下连接的预制混凝土柱，预制混凝土柱的顶部设置有圆钢管套管和灌浆套筒，预制混凝土柱的侧面设置有与各个灌浆套筒内腔相通的注浆口和出浆口，预制混凝土柱的底部凸出有圆钢管混凝土抗剪键和与连接钢筋，拼接各段预制混凝土柱时，圆钢管混凝土抗剪键插入圆钢管套管内，连接钢筋插入灌浆套筒内，灌浆套筒和圆钢管套管内充满高强灌浆料；本发明可以确保所有套筒内的灌浆料均填满密实，无需在试件套筒插入钢筋后再进行复杂的分仓和压力注浆环节，大大降低传统方式压力注浆的施工难度和质量风险，不会存在注浆不密实的空洞等缺陷，确保连接位置的传力安全可靠。
