Cast-in-place pile fixing device for building foundation construction
The invention belongs to the technical field of cast-in-place pile construction, and particularly discloses a cast-in-place pile fixing device for building foundation construction, the cast-in-place pile fixing device for building foundation construction comprises a bearing disc, a plurality of penetration nails and an elastic base, and the tail ends of the penetration nails are hinged to the edge of the bearing disc through shafts; the elastic base is connected with the bottom of the bearing disc through an elastic piece, a plurality of guiding slope tables are arranged at the top of the elastic base around the elastic piece, guiding slopes are arranged on the top faces of the guiding slope tables and located under the corresponding penetration nails, and the heights of the guiding slopes are gradually reduced in the direction away from the circle center of the bearing disc. All the penetrating nails are vertically folded under the action of gravity; when the bearing disc bears concrete to enable the elastic base to be compressed, the head ends of the penetration nails slide along the corresponding guide slopes, so that the penetration nails rotate to be horizontal and extend in the radial direction of the bearing disc. The fixing device can effectively solve the technical problem that when concrete is poured into a pile hole of a cast-in-place pile, the bottom of a reinforcement cage is prone to inclining or shaking.
本发明属于灌注桩施工技术领域，具体公开了一种用于建筑基础施工的灌注桩固定装置，包括承载盘、若干贯入钉及弹性基座，贯入钉的尾端与承载盘边缘轴铰；弹性基座通过弹性件与承载盘底部连接，弹性基座顶部围绕弹性件设有若干引导坡台，引导坡台顶面设有引导斜面，引导斜面位于对应的贯入钉的正下方，引导斜面的高度沿远离承载盘圆心的方向逐渐降低，当弹性基座处于自然状态时，全部贯入钉在重力作用下竖直收拢；当承载盘承载混凝土，以使弹性基座压缩时，贯入钉的首端沿对应的引导斜面滑动，以使贯入钉转至水平，并沿承载盘的径向延伸。该固定装置能够有效解决于灌注桩的桩孔内灌注混凝土时，钢筋笼底部容易发生倾斜或晃动的技术问题。
