Step 1）Soil layer 13 under box beam 12 is tamped.
Step 2）Subgrade case 7 is equipped with according to upper load.
Step 3）Steel pipe column 8 is installed on subgrade case.
Step 4）Steel I-beam 9 is installed on steel pipe column.
Step 5）Bailey beam 10 is installed on steel I-beam.
Step 6）Spread flitch and template successively from the bottom to top in Bailey beam 10（Not shown in figure）, and the colligation in template
Reinforcing bar after-pouring concrete formation box beam 12, completes construction.
Step 1）In, it is contemplated that the security of construction and the reliability on construction basis, the earth bearing strength of soil layer, which need to reach, often puts down
Square 8 tons of rice.
The step 3 and step 4）Realized between middle steel pipe column and steel I-beam by the way of pin connection quick, removable
The installation unloaded.
In the present embodiment, step 3 and step 4）Middle use steady pin realizes pin connection, mainly by the plug division 1 of cylindricality, set
It is made up of the rectangle clamping block 2 and latch 5 of conduit 21.One end of plug division 1 is provided with step 11, and the other end, which is provided with, to be used to store
The groove 22 of clamping block 2.Latch 5 passes through the conduit 21 of clamping block, and wears and connect with groove 22, realizes the activity of clamping block 2 and plug division 1
Connection.When the length direction of clamping block 2 is vertical with cylindricality plug division axis, clamping block 2 makees a pair of parallel with the formation of step 11
Containment surfaces, two containment surfaces with conduit realized relative to the motion of latch it is mutual closer or far from, when clamping block 2 length
When spending the diameter parallel in direction and plug division 1, clamping block 2 is contained in groove 22.
The Fast Installation of the steady pin comprises the following steps：
a）Rotating clamping block 2 makes clamping block 2 be accommodated in the groove 22 of plug division 1, and steady pin is connected into steel pipe column 8 and road
In the mounting hole of base case 7 or steel pipe column 8 and steel I-beam 9, referring to Fig. 8.
b）Clamping is pulled to after extreme position for 2 pieces along the axis direction of plug division 1, rotating clamping block 2 makes the side of clamping block 2
Face is vertical with the axis of plug division 1, referring to Fig. 9.
c）Clamping block 2 is moved to the mutually close corresponding direction of two containment surfaces, until the side of latch and conduit inwall
During interference fit, Fast Installation is completed.The movement of clamping block can be according to using hand or instrument the need for actual close-fitting degree in the step
Realize, instrument can be using T-shaped hammer etc., referring to Figure 10.
The method for dismounting corresponding with above-mentioned installation method only need with hand or instrument movement clamping block i.e. can be achieved square tube with
The dismounting of plate, compares the operation with twisting rotation screw, very simply, it is easy to operate.
Further, such as Fig. 7, conduit 21 is inclined straight trough.Likewise, the conduit may be alternatively configured shaped groove, such as arc
Shape groove（Not shown in figure）.
In the construction basis for the cast-in-place high ferro box beam that the present embodiment is provided, the steel plate roadbed box of use is the work of recycling
Tool, and traditional bored concrete pile and strip footing is expendable consumed product.And traditional long construction period with bored concrete pile, it is necessary to be set
Standby, pouring strip footing needs the time, many using equipment, and the construction time is long.Technical scheme only needs soil layer to go through reality, directly
Steel plate roadbed box is hung to steel pipe column position directly below.On the other hand, steel I-beam and steel pipe in traditional construction method
Between post, largely using being welded to connect or being threadedly coupled between steel pipe column and strip footing, installation effectiveness is low, not easy to operate,
Connected in technical scheme using assembled, connection method is connected using bearing pin, connect quick and easy reliable, saving of labor
It is time saving.
