Besides affecting the installation accuracy of equipment, the deviation of the reserved holes of the foundation bolts brings other problems to the field engineering construction. For example, if the reserved holes exceeding the deviation are re-milled, not only are manpower and material resources wasted, but also concrete foundations can be damaged, and potential safety hazards are caused. Therefore, a new foundation bolt is urgently needed in a construction site to reduce the requirement for deviation of reserved holes of the foundation bolt, thereby saving cost and improving construction efficiency.

the double-end screw above the sliding sleeve is sleeved with a cylindrical sleeve, an inner thread is arranged on the inner wall of the upper portion of the cylindrical sleeve, the cylindrical sleeve is in threaded connection with the upper portion of the double-end screw, and the rotary cylindrical sleeve is used for pushing the sliding sleeve to move downwards.
Further, rectangular grooves are excavated at the lower parts of the double-headed screws, and the barb rods are connected in the rectangular grooves.
Further, the lower extreme of rectangle groove is connected with the axle center pole, and barb pole lower extreme is equipped with the through-hole, and the axle center pole is worn to locate in the through-hole of barb pole.
Further, long strip-shaped long grooves are formed in the upper gasket and the lower gasket and are used for being connected with the double-headed screw.
The utility model has the beneficial effects that: the effect of expanding the head is achieved through the barb rod on the double-headed screw rod, the overall tensile strength of the bolt is enhanced, and meanwhile the extensibility of the double-headed screw rod effectively guarantees the perpendicularity and stability of the bolt during pouring. The circular hole-reserving gasket has the function of adjusting and compensating the position deviation of the reserved hole, and the double nuts have the effect of preventing the rotation during the fastening of the bolts.
