Link into an integrated entity, each steel formwork trolley element length is 12.5m～15m, and whole steel formwork trolley is the longest to reach 30m.
Embodiment two: with reference to Fig. 8 to Figure 10, and referring to figs. 1 to Fig. 7, the split of the present invention integrated underpass steel is described
The construction method of formwork jumbo, specifically comprises the following steps that
Step one: template group is arranged on steel formwork trolley, and is arranged in order three frames along underpass 50 transverse section
Posture mould plate supporting device 100,200,300, three frame-type mould plate supporting devices 100,200,300 reach assignment position
Afterwards, its lengthwise position is connected using detachable box-shaped beam 20 up and down, and is stably and firmly located in underpass 50, framework
Formula mould plate supporting device 100,200,300 after vertical hydraulic jack group 105,205,305 is adjusted to calibrated altitude, adjacent
Two frame-type mould plate supporting devices 100,200,300 between tear backform plate supporting device 400,500 open after bolt connection, make frame
Posture mould plate supporting device 100,200,300 and after tear on backform plate supporting device 400,500 5 pieces of fixing monomer top templates open
110th, 410,210,510,310 it is located at same level, then, progressively carry out concrete in the construction cell of underpass 50
Pouring construction；
Step 2: when the concrete of current construction cell reaches some strength, as shown in figure 9, in transverse hydraulic oil cylinder
Under the control of group 204 and vertical hydraulic jack group 105,205,305, make on frame-type mould plate supporting device 100,200,300
Three pieces of monomer top templates 110,210,310 decline, and the side template 111,311 of both sides shrinks, and tear top template open after unclamping two groups and prop up
The connection of support arrangement 400,500 and frame-type mould plate supporting device 100,200,300, as shown in Figure 10, frame-type after contraction
The outer profile size of mould plate supporting device 100,200,300 is less than the overall size of underpass 50 so that it can be in walking
The underpass 50 that is driven through of mechanism enters next construction cell；Now, frame-type mould plate supporting device 100,200,300
Front end leave upper and lower two box-shaped beams 20, to ensure the globality of frame-type mould plate supporting device 100,200,300, and tear open
Except the box-shaped beam 20 of other positions is so that when frame-type mould plate supporting device 100,200,300 moves forward, can tear top open after getting around
Mould plate supporting device 400,500 is smooth to enter next construction cell.
Step 3: after the concrete strength of current construction cell reaches design requirement, then by after tear open top template support dress
Put 400,500 and move to next construction cell, be connected with frame-type mould plate supporting device 100,200,300, form punching block again
Pallet car, carry out next construction cell pours operation.Above-mentioned concrete strength design requirement refers to that concrete strength meets
The regulation of " concrete structure engineering construction quality accident specification ".
The construction method of the split integrated underpass steel formwork trolley of the present invention, first, tears top template open by after two groups
Support meanss are bolted between adjacent two frame-type mould plate supporting device respectively, form steel formwork trolley, contentedly
The pouring construction of lower channel concrete, whne concrete strength reach necessarily require when, frame-type mould plate supporting device is in hydraulic pressure system
Shrink in the presence of system so that its can before move up into next construction cell, and recover original extended configuration, tear open after reservation
Backform plate supporting device is then after underpass concrete reaches design requirement, then removes next construction cell of entrance, with framework
Formula mould plate supporting device is assembled into the pouring construction that steel formwork trolley carries out concrete again.By the construction method of the present invention,
Not only can make underpass continuous concreting molding, and due to after tear the presence of backform plate supporting device open, frame can be made
Posture mould plate supporting device is when underpass concrete strength reaches some strength, you can moves to next construction cell and continues
Construction so that steel formwork trolley can do sth. in advance 10～15 heaven-made vertically move, realize early form removal and construct, decrease construction cost, contract
The short construction period, and ensure that construction quality and improve efficiency of construction.
Preferably, in above-mentioned steps two, when underpass 50 concrete strength reaches the 60%～70% of design requirement,
The top template 110,210,310 on frame-type mould plate supporting device 100,200,300 is made to decline, the side template 111,311 of both sides
Shrink, and pass through underpass 50 to enter next construction cell.
Embodiment three: combine Figure 11, and refering to Fig. 1 to Figure 10, the split of the present invention integrated underpass steel form is described
The construction method of chassis, from unlike embodiment two, the present embodiment is that have some bend segmental arc situations in underpass 50
Under pouring construction operation, as shown in figure 11, when the bend segmental arc having radius r to reach 400m in underpass, by punching block pallet
Car resolves into the steel formwork trolley unit 1 that length l is 12.5m length, and the box-shaped beam 20 on steel formwork trolley is removed, and directly will
Three frame-type mould plate supporting device 100,200,300 bolt connections become an entirety so that steel formwork trolley narrowed width, just
In moving forward along bend segmental arc in underpass 50, because steel formwork trolley shortens so that underground after concreting
The profile of the bend segmental arc of passage 50 can be closer to the arc shape of design requirement.The construction method of the present embodiment, by three frames
The direct bolt connection of posture mould plate supporting device, its narrowed width, to meet, there is pouring of bend segmental arc underpass concrete
Build construction, flexible operation, can treatment in accordance with local conditions so that the suitability of steel formwork trolley of the present invention is higher.
Foregoing description is only the description to present pre-ferred embodiments, not any restriction to the scope of the invention, this
Any change that the those of ordinary skill in bright field does according to the disclosure above content, modification, belong to the protection of claims
Scope.
