根据大量现有基桩竖向抗拔静载荷试验、单桩竖向抗压静载荷中的锚桩法试验,针对所需的传力抗拉钢筋焊接时遇到的不垂直、钢筋受力不均匀以及焊接效率低等问题,研制并试制出一种基桩抗拔试验用的由轮辐式、连接体传力马鞍及可调节高度螺杆所组成的组合传力装置,通过工程的试用,该装置设计合理,现场安装方便,能有效解决锚桩受拉钢筋的垂直受力问题,通过螺杆和马鞍的连接可快速进行轮辐式连接体与反力梁的高度调节,连接装置可重复利用,锚桩钢筋与轮辐式连接体的连接采用嵌入轮辐式导槽绑搭接焊的墩头来传递抗拉力,能够做到抗拉钢筋均匀受力,装置可用于单桩抗拔以及锚桩法等多种抗拔试验需求的场合。
According to a large number of existing static vertical pile anti-static load test, single vertical pile static load test in the anchor pile method, for the required transmission force of the tensile bar welding encountered not vertical, reinforced not force Uniform and low welding efficiency and other issues, the development and trial production of a base pile pull-pull test by the spokes, the connecting body force saddle and adjustable height screw composed of a combination of force transmission device, through the engineering trial, the device The utility model has the advantages of reasonable design and convenient installation on site, which can effectively solve the vertical force problem of the tension reinforcement of the anchor pile. The height adjustment of the spoke connection body and the reaction force beam can be quickly carried out by the connection of the screw rod and the saddle; the connection device can be reused; The connection between steel bar and spoke connector adopts the pier which is embedded in the spoke guide and is bonded and welded to transmit the tensile force so that the tensile bar can be uniformly stressed. The device can be used for the anti-pull of single pile and the method of anchor pile Kind of anti-pull test needs of the occasion.
