At this time, the second crossbar 13 will slide. At this time, the distance between the first longitudinal rod 1 and the third longitudinal rod 15 can be extended. When it is extended to correspond to the gap between the bridges, the whole body is passed through the gap between the bridges, and then the support plate 16 is hung on the surfaces on both sides of the gap of the bridge. At this time, the position of the whole body can be fixed, and then the operator goes down to the first crossbar 12 and the second crossbar 13 to construct the bridge diaphragm. After the construction is completed, the operator leaves and the whole body is lifted out from the gap between the bridges, and then the third longitudinal rod 15 is pushed to the first longitudinal rod. When the second cross bar 13 is retracted and reset, the third longitudinal bar 15 is pulled away from the first longitudinal bar 1 according to the size of the gap between the bridges. At this time, the second cross bar 13 will slide. At this time, the distance between the first longitudinal bar 1 and the third longitudinal bar 15 can be extended. When it is extended to correspond to the gap between the bridges, the whole body is passed through the gap between the bridges, and then the support plate 16 is hung on the surfaces on both sides of the gap between the bridges. At this time, the position of the whole body can be fixed, and then the operator goes down to the first cross bar 12 and the second cross bar 13 to construct the bridge diaphragm. After the construction is completed, the operator leaves and hoists the whole body out from between the gaps of the bridges, and then Pushing the third longitudinal rod 15 toward the first longitudinal rod 1 can retract and reset the second crossbar 13. When the depth of construction of the bridge diaphragm is different, the fixing pin 34 is taken out and then the slide bar 3 is pulled to slide in the sleeve 32. At this time, the length between the sleeve 32 and the slide bar 3 can be changed to match the depth of construction. After aligning the first fixing hole 31 with the second fixing hole 33, the fixing pin 34 is inserted back. After adjusting the length between the first crossbar 12 and the second crossbar 13, the screw rod 4 can be driven to rotate by rotating the rotating rod 41 to move the end of the screw rod 4 toward the top of the second crossbar 13. When the end of the screw rod 4 contacts the second crossbar 13, the screw rod 4 can be The position of the second cross bar 13 is fixed. After use, the rotating rod 41 can be rotated in the opposite direction to drive the screw rod 4 away from the second cross bar 13 to release it. After the whole is hoisted to the construction position, the lock buckle 51 is hung on the embedded steel bars on the bridge gap. At this time, the sleeve 32 and the embedded steel bars of the bridge can be connected with the lock buckle 51 through the steel wire 5. After use, the lock buckle 51 is removed from the embedded steel bars. When the whole is lowered to the construction position, the steel column 61 is passed through the ring 6. At this time, the steel column 61 is located on both sides of the bridge gap. At this time, the whole can be protected. When the support plate 16 is hung on the bridge deck, the fixed cone 7 at the bottom of the support plate 16 will contact the bridge deck.
