Abstract
Description
Technical Field
[0001] This utility model relates to the foundation for power equipment installation, and in particular to a positioning mechanism for pre-embedding anchor bolts in reserved holes of a square concrete foundation base for electrical equipment installation. Background Technology
[0002] In the fields of thermal power, wind power, photovoltaic power, and power transmission and distribution, electrical equipment is installed on equipment foundations. These foundations are typically cast-in-place concrete foundations with pre-embedded anchor bolts. The electrical equipment is then installed on these foundations using these anchor bolts. During the pouring of the concrete foundation, holes for installing the anchor bolts (i.e., pre-drilled holes) are pre-drilled, and the cast-in-place concrete foundation cap is completed. When the electrical equipment is installed on the foundation cap, the anchor bolts are positioned in the pre-drilled holes, and then cement mortar is poured into the pre-drilled holes to fix the anchor bolts. This method is called the secondary grouting fixing method for anchor bolts. Many electrical equipment require high precision in terms of the density and level of the contact surface between the foundation cap and the equipment. To meet these requirements, the secondary grouting fixing method is generally used to pre-embed the anchor bolts. However, accurately positioning the anchor bolts in the pre-drilled holes and improving the construction efficiency of the secondary grouting has become a problem that needs to be solved on-site. Summary of the Invention
[0003] This utility model provides a precise positioning mechanism for anchor bolts embedded in pre-drilled holes in square concrete foundations, which realizes the precise positioning of anchor bolts in pre-drilled holes and improves the construction efficiency of secondary grouting.
[0004] This utility model solves the above technical problems through the following technical solution: A precise positioning mechanism for pre-embedded anchor bolts in pre-drilled holes in a square concrete foundation includes a cast-in-place square foundation. A first, second, third, and fourth pre-drilled holes are respectively provided on the top surface of the square foundation. An angle steel square frame is fitted onto the top of the square foundation. A first and second longitudinal elongated through holes are respectively provided on the left side of the angle steel square frame, and a third and fourth longitudinal elongated through hole are respectively provided on the right side of the angle steel square frame. The mechanism is described in the first longitudinal elongated through hole. An upper steel plate crossbeam is movably installed between the square and the third longitudinal elongated through hole. A first anchor bolt and a second anchor bolt are respectively installed on the upper steel plate crossbeam. The lower end of the first anchor bolt is set in the first reserved hole, and the lower end of the second anchor bolt is set in the second reserved hole. An upper left transverse elongated through hole is provided at the left end of the upper steel plate crossbeam, and an upper right transverse elongated through hole is provided at the right end of the upper steel plate crossbeam. The upper left transverse elongated through hole is cross-connected with the first longitudinal elongated through hole, and the upper right transverse elongated through hole is cross-connected with the third longitudinal elongated through hole.
[0005] An upper left fixing bolt is inserted between the upper left transverse elongated through hole and the first longitudinal elongated through hole, and an upper right fixing bolt is inserted between the upper right transverse elongated through hole and the third longitudinal elongated through hole; an upper left through hole is provided on the left side of the upper steel plate crossbeam, and an upper right through hole is provided on the right side of the upper steel plate crossbeam. The first anchor bolt is inserted into the upper left through hole, and the second anchor bolt is inserted into the upper right through hole.

[0009] The present invention will now be described in detail with reference to the accompanying drawings: A precise positioning mechanism for pre-embedded anchor bolts in pre-drilled holes in a square concrete foundation includes a cast-in-place square foundation 1. A first pre-drilled hole 2, a second pre-drilled hole 3, a third pre-drilled hole 4, and a fourth pre-drilled hole 5 are respectively provided on the top surface of the square foundation 1. An angle steel square frame 6 is fitted onto the top of the square foundation 1, with each side of the angle steel square frame 6 engaging with the edge of the top surface of the square foundation 1 to position the angle steel square frame 6. A first longitudinal elongated through hole 7 and a second longitudinal elongated through hole 8 are respectively provided on the left side of the angle steel square frame 6, and a third longitudinal elongated through hole 9 and a fourth longitudinal elongated through hole 10 are respectively provided on the right side of the angle steel square frame 6. An upper steel frame is movably arranged between the first longitudinal elongated through hole 7 and the third longitudinal elongated through hole 9. The upper steel plate crossarm 11 is provided with a first anchor bolt 12 and a second anchor bolt 13. The lower end of the first anchor bolt 12 is set in the first reserved hole 2, and the lower end of the second anchor bolt 13 is set in the second reserved hole 3. An upper left transverse elongated through hole 14 is provided at the left end of the upper steel plate crossarm 11, and an upper right transverse elongated through hole 15 is provided at the right end of the upper steel plate crossarm 11. The upper left transverse elongated through hole 14 is cross-connected with the first longitudinal elongated through hole 7, and the upper right transverse elongated through hole 15 is cross-connected with the third longitudinal elongated through hole 9. The distance between the first anchor bolt 12 and the second anchor bolt 13 can be accurately determined according to the drawings. By moving the upper steel plate crossarm 11 left and right and back and forth, the first anchor bolt 12 and the second anchor bolt 13 are accurately positioned in the reserved holes.
[0010] An upper left fixing bolt 16 is inserted between the upper left transverse elongated through hole 14 and the first longitudinal elongated through hole 7. An upper right fixing bolt 17 is inserted between the upper right transverse elongated through hole 15 and the third longitudinal elongated through hole 9. An upper left through hole 18 is provided on the left side of the upper steel plate crossbeam 11, and an upper right through hole 19 is provided on the right side of the upper steel plate crossbeam 11. A first anchor bolt 12 is inserted into the upper left through hole 18, and a second anchor bolt 13 is inserted into the upper right through hole 19. After positioning is completed, the position of the upper steel plate crossbeam 11 can be fixed by the above two fixing bolts. A first lower fixing nut 20 is provided between the bottom surface of the upper steel plate crossbeam 11 and the first anchor bolt 12; a second upper fixing nut 21 is provided between the top surface of the upper steel plate crossbeam 11 and the first anchor bolt 12; a third lower fixing nut 22 is provided between the bottom surface of the upper steel plate crossbeam 11 and the second anchor bolt 13; and a fourth upper fixing nut 23 is provided between the top surface of the upper steel plate crossbeam 11 and the second anchor bolt 13. By tightening the upper and lower fixing nuts, the anchor bolt is vertically installed in the reserved hole.
[0011] The method for determining the position of the lower steel plate crossbeam is the same as the method for determining the position of the upper steel plate crossbeam 11. After the four anchor bolts are positioned, cement mortar is poured into the reserved holes. After the poured cement mortar has set, the second upper fixing nut 21 and the fourth upper fixing nut 23 are removed. Then the entire angle steel square frame 6 is moved vertically upward, and the positioning mold is removed from the square foundation 1 for positioning the next foundation.
