Displacement loading device for foundation pit concrete support
The invention relates to a displacement loading device for foundation pit concrete support, which is arranged in a groove of an enclosure purlin, provides support for an enclosure wall above, and comprises two first wedge-shaped blocks, a second wedge-shaped block, a center hole jack and a threaded rod, the bottom surfaces of the first wedge-shaped blocks are in contact with the bottom surface of the groove, the two first wedge-shaped blocks are oppositely arranged, and the center hole jack is connected with the threaded rod. The inclined surface of the first wedge-shaped block is positioned at the upper part and is inclined from the middle part of the groove to the inclined upper part; the second wedge-shaped block comprises two inclined surfaces, the two inclined surfaces are in contact with the inclined surfaces of the two first wedge-shaped blocks respectively, and the top surface of the second wedge-shaped block is in contact with the enclosure wall; the center hole jack is arranged on the outer side of one of the first wedge-shaped blocks; the threaded rod sequentially and horizontally penetrates through the two first wedge-shaped blocks, one end of the threaded rod is connected with the center hole jack, and the other end of the threaded rod is connected with the other first wedge-shaped block. The center hole jack is used for applying tiny jacking force, so that large concrete supporting axial force is generated.
本发明涉及一种用于基坑混凝土支撑的位移加载装置，设置于围檩的凹槽内，为上方的围护墙提供支撑，包括两个第一楔形块、一个第二楔形块、穿心式千斤顶以及螺纹杆，第一楔形块的底面与凹槽的底面接触，两个第一楔形块相对设置，第一楔形块的斜面位于上方并从凹槽的中部向斜上方倾斜；第二楔形块包括两个斜面，两个斜面分别与两个第一楔形块的斜面接触，第二楔形块的顶面与围护墙接触；穿心式千斤顶设置于其中一个第一楔形块的外侧；螺纹杆依次水平贯穿两个第一楔形块，且一端与穿心式千斤顶连接，另一端与另一个第一楔形块连接。本申请利用穿心式千斤顶施加微小的顶力从而产生较大的混凝土支撑轴力。
