Embodiment
1~Fig. 5 of reference picture, the present invention are a kind of erection methods of split type level bridges, and the split type level bridges include base
1, one folding first pontic 4 of seat and at least one foldable second pontic 5, comprise the following steps：
First, will be holded up in the first pontic 4 of folded state, the center of rotation of the first pontic 4 is above, the first pontic 4
Both ends be located at lower section, one end and the pedestal 1 of the first pontic 4 are rotatably coupled；
2nd, the first pontic 4 carries folding-unfolding mechanism, drives the first pontic 4 to deploy by folding-unfolding mechanism, and control the first pontic
4 are gradually reduced, and the other end to the first pontic 4 installs；
3rd, the second pontic 5 is pushed on the first pontic 4 for having set up, the second pontic 5 in place after, by the one of the second pontic 5
End is connected with the first pontic 4, and the second pontic 5 carries folding-unfolding mechanism, is driven and deployed by folding-unfolding mechanism, the second pontic 5 of control
The other end gradually decreases down to be bonded with the first pontic 4；
4th, the connection between the first pontic 4 and the second pontic 5 is released, by the first pontic 4 and the second pontic 5 in side pivot
Connect, be then lifted out the second pontic 5 so that the second pontic 5 rotates relative to the first pontic 4, now the second pontic 5 and the first pontic 4
In parallel arranged on same plane；
Step 5: the connection of the first pontic 4 and pedestal 1 is released, and lifting the first pontic 4 and the second pontic 5 are so as at it
Lower section erection support, complete to set up.Also have one second pontic 5 is moved into the former institute of first pontic 4 between step 1 and step 2
The step of locating position, preferably to regard the second pontic 5 as the counterweight for setting up the first pontic 4；Turned in step 4 in the second pontic 5
After having turned, the connection of the first pontic 4 and the second pontic 5 is released, the second pontic 5 is translated into setpoint distance.Above-mentioned split type steelframe
The erection method of bridge sets up efficiency high, makes full use of the deadweight of the first pontic 4 and the second pontic 5, mitigates the requirement to counterweight, the
Counterweight is used as by the second pontic 5 and pedestal 1 when one pontic 4 is set up, the second pontic 5 is very low to counterweight requirements when setting up, and second
