Specific embodiment
The present embodiment is illustrated by taking the wedge block of prefabricated box beam and pre-embedded bolt as an example, as depicted in figs. 1 and 2, auxiliary
Rectangle frame 1 is helped in mold to be welded using the closing of 20# channel steel, length is not less than 13000mm, the not small precast beam bottom width of width,
The composite plate 2 that 1 port top surface of rectangle frame is completely spread is 5+1 clad steel plate, and by being welded and fixed, the wherein reserved installation of clad steel plate is led
The pre-buried hole of mold；Inclined plate 3 is made into chamfering using 50 × 50mm plate, and the supporting rod 7 with channel steel welding is 12 reinforcing bars.
As shown in Figure 3 and Figure 4, lower template 4 uses 2cm steel form in the present embodiment, having a size of 700 × 600mm, in 2cm
The handle hole 13 that diameter is 300mm is opened in steel form center, while in the four Angle Position welding 40 of 2cm punching block back
Sleeve 9 and installation and adjustment bolt 8 are adjusted, bolt 8 and precast beam pedestal is adjusted and passes through sleeve connection, 2cm steel form mounting height
Adjusting bolt 8 is turned by handle hole 13 to be adjusted；Cope plate 5 uses 1cm steel form, the steel having a size of 700 × 500mm
Plate carries out setting location hole according to determining 11 position of support pre-embedded bolt.
In the present embodiment, adjustment hole 12,12 side of setting of adjustment hole are arranged according to 10 size of connection sleeve of pre-embedded bolt 11
