Embodiment Construction
[0020] The present invention is described in detail below in conjunction with the accompanying drawings:
[0021] A rear-buried anchor bolt suspension positioning mechanism in concrete foundation pouring of a street lamp, comprising a concrete foundation pit 1, in which concrete 2 is poured in situ, and are respectively arranged on the ground outside the concrete foundation pit 1 There are positioning reference lines 3 before and after installation of street light poles and left and right positioning reference lines 4 for installation of street light poles. On the cast-in-place concrete 2, a square PVC board 5 is suspended, and the top surface of the square PVC board 5 is respectively provided with a front and rear suspension board The positioning reference line 6 and the left and right positioning reference line 7 on the suspension board are provided with a pair of pre-buried U-bolt penetration holes 8 in the front and rear directions on the front and rear positioning referenc...

The invention discloses a suspension positioning method for a post-buried type foundation bolt in street lamp concrete foundation pouring. The method solves the problem of how to consider the position accuracy of a pre-buried bolt and the strength of a concrete foundation in foundation bolt construction. Two U-shaped bolts are selected as embedded foundation bolts and are hung and distributed on a square PVC (polyvinyl chloride) plate in a cross manner to form a balanced and stable frame body, a positioning reference mark line of the foundation bolts is arranged on the top end surface of the square PVC plate, and the top ends of the two U-shaped bolts penetrate through the square PVC plate through locking nuts and then are fixed; after concrete pouring is completed in a concrete foundation pit at a time, the formed frame body is immediately placed in the poured concrete, the square PVC plate is made to suspend on the upper top face of the poured concrete, after the concrete is slightly solidified, horizontal arrangement and position adjustment of the square PVC plate are completed, and the embedded bolt accurate in positioning can be obtained.
Description
technical field [0001] The invention relates to an anchor bolt on a concrete foundation, in particular to a suspension positioning mechanism and a suspension positioning method using a back-buried anchor bolt in the pouring of a street lamp concrete foundation. Background technique [0002] Some street light poles are made of steel pipes. The foundation of these street light poles is concrete foundation, and anchor bolts are embedded on the concrete foundation to connect the street light poles on the foundation; [0003] The pre-embedded bolts in the concrete foundation generally use two methods. The first method is the direct-buried type, which is to fix the pre-embedded anchor bolts on the reinforced skeleton in the foundation, and pour the foundation concrete in one shot to form the foundation connecting the equipment. Bolts, this method is difficult to fix with pre-embedded anchor bolts, and the defect of position deviation is prone to occur during concrete pouring. The ...
