Threaded inserting rod type precast pile quick connecting piece
The invention discloses a threaded insertion rod type precast pile quick connecting piece, and relates to a concrete pile, and aims to solve the problem of lack of axial limitation between occlusion petals, the threaded insertion rod type precast pile quick connecting piece is characterized by comprising an upper embedded part and a lower embedded part, the upper embedded part is provided with a bushing, the bushing is provided with occlusion petals, and the lower embedded part is provided with a threaded insertion rod. Compression springs are arranged between the occlusion petals and the top face of an inner cavity of the upper embedded part, the lower embedded part is provided with an inserting piece, the occlusion petals are connected in an attached mode to define a hollow columnar structure and are provided with outer circumferential faces, the occlusion petals are provided with length extension sections, spiral grooves are formed in the outer circumferential faces, and spiral spring steel strips are arranged on the spiral grooves in a sleeved mode. According to the threaded insertion rod type precast pile quick connecting piece, on one hand, the situation that the multiple occlusion petals are independently scattered, and consequently assembling is not easy is avoided, on the other hand, the relative movement degree of the occlusion petals in the central axis direction is limited through the spiral spring steel strips, and therefore dislocation of the occlusion petals is avoided.
本发明公开了一种螺纹插杆式预制桩快速连接件，涉及混凝土桩，旨在解决咬合瓣之间缺乏轴线向的限制，其技术方案要点是：一种螺纹插杆式预制桩快速连接件，包括上预埋件以及下预埋件，上预埋件设置有衬套，衬套设置有咬合瓣，咬合瓣与上预埋件的内腔顶面之间设置有压缩弹簧，下预埋件设置有插件，多个咬合瓣贴合连接围成空心柱状结构，且具有外圆周面，多个咬合瓣设置有长度延伸段，外圆周面开设有螺旋槽，螺旋槽套设有螺旋弹簧钢条。本发明的一种螺纹插杆式预制桩快速连接件，一方面避免多个咬合瓣独立散乱，而导致不易装配，另一方面由螺旋弹簧钢条限制多个咬合瓣沿中轴线方向的相对活动度，从而避免咬合瓣发生错位。
