The utility model is compared with existing tower crane, concrete pump, derrick, has following advantage: 1. creeping formwork and derrick organically are combined as a whole, have improved work efficiency; 2. derrick is supported on the hoistway wall, and climbs, save steel along with the rising of hoistway wall, good in economic efficiency; 3. simple in structure, be convenient to dismounting and operation; 4. climb and adopt guide rail to contact, reduced the lifting resistance, promote good stability with pulley.
Below in conjunction with accompanying drawing the utility model is illustrated:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A section drawing of Fig. 1.
As shown in Figure 1, 2, the utility model is by head sheave beam 1, head sheave 2, outrigger 3, bottle gouard moved by hands or electric block 4,5, steel wire rope 6, internal mold 7, external mold 8, Bolt 9, outrigger 10, derrick 11, the borehole wall 12, guide rail 13, cage 14, Spandrel girder 15, bolt 16, land wheel 17, hoist engine 18, draw-beam 19, Pull bar 20, pulley 21, outrigger spandrel girder 22, flooring 23, steel wire rope 24 Common formation.
Embodiment: derrick bearing beam 15 is supported on hoistway wall 12, and bolt up is in flooring 23 tops, and derrick 11 bolt ups are in derrick bearing beam 15 upper ends.Derrick 11 outsides are with outrigger 10, and also bolt up is on outrigger bearing beam 22 for outrigger 10, and outrigger bearing beam 22 also is supported on the hoistway wall 12, also is anchored on flooring 23 tops with bolt 16.The draw-beam 19 on outrigger 10 tops is provided with the bottle gouard moved by hands or the electric block 5 of derrick 11 usefulness of climbing.Derrick 11 is provided with guide rail 13, and outrigger 10 respectively is provided with 4 pulleys 21 up and down.During formwork, outrigger 10 is connected as a single entity by pull bar 20 and internal mold 7, and internal mold 7 is connected as a single entity with external mold 8 usefulness bolts 9.Four limits, derrick 11 tops are provided with lifting outrigger 3, and lifting outrigger 3 is provided with bottle gouard moved by hands or the electric block 4 that is used to promote internal mold 7, external mold 8 and outrigger 10.Derrick 11 tops are provided with head sheave beam 1, head sheave beam 1 is provided with head sheave 2, ground is provided with land wheel 17 and winch 18, be provided with cage (or hopper) 14 in the derrick 11, steel rope 24 is pulled to head sheave beam 1 from ground, as the guide rail of cage 14, steel rope 6 is connected in winch 18 by head sheave 2 and land wheel 17 with cage 14.
During use, water the high ferro-concrete hoistway wall 12 of two floors by drawing earlier, should reserve the hole of placing bearing beam 15,22.When hoistway wall 12 intensity reach 20Mpa, derrick bearing beam 15 is inserted in the hole that hoistway wall 12 reserve, be anchored on the flooring 23 with bolt 16, with derrick 11 bolt ups on derrick bearing beam 15.Then outrigger bearing beam 22 is inserted in the hole of hoistway wall 12 reservations, be anchored on the flooring 23 with bolt 16, again outrigger 10 is enclosed within derrick 11 outsides, bolt up is on outrigger bearing beam 22, continue the high hoistway wall 12 of pouring first floor with pull bar 20 and bolt 9 well, with 8 of internal molds 7, external mold.When the intensity for the treatment of newly to water hoistway wall 12 reaches 20MPa, with bottle gouard moved by hands 4 outrigger 10 that climbs, internal mold 7, external mold 8, when climbing outrigger 10, should loosen earlier and outrigger bearing beam 22 bonded assembly bolts, make outrigger 10 be in supreme restrained condition down, when climbing, pulley 21 on the outrigger 10 rises along the guide rail on the derrick 11 13, and at this moment, the weight bearing of outrigger 10 is on derrick 11, assigned position climbs, standby outrigger bearing beam 22 is inserted in the hole of hoistway wall 12 reservations, put down outrigger 10, the outrigger bearing beam is anchored on the flooring 23 with bolt 16, the sheet bolt is anchored on outrigger 10 on the outrigger bearing beam 22, unloads the outrigger bearing beam 22 of original position when not climbing.Subsequently, formwork continues the high hoistway wall 12 of pouring first floor, then with bottle gouard moved by hands 5 derrick 11 that climbs, before climbing, should loosen earlier and derrick bearing beam 15 bonded assembly bolts, make derrick 11 be in the supreme state of constraint down, when climbing, the guide rail 13 on the derrick 11 rises along the pulley on the outrigger 10 21, at this moment, the weight bearing of derrick 11 is on outrigger 10, and the assigned position that climbs inserts standby derrick bearing beam 15 in the hole of hoistway wall 12 reservations, put down derrick 11, with bolt 16 derrick bearing beam 15 is anchored on the flooring 23, derrick 11 is anchored on the derrick bearing beam 15, unload the derrick bearing beam 15 of former placement when not climbing with bolt.Like this, can carry out the circulation second time, reciprocation cycle, hoistway wall 12 constantly pouring raises, and derrick 11 also constantly climbs thereupon.During hoisting heavy, start winch 18, can realize cage (or hopper) 14 up-and-down movements.In case of necessity, derrick 11 can be set up driving lever, in order to surpluses such as lifting reinforcing bars.
