Description
Technical field
The present invention relates to the realm of building construction, especially a kind of steel reinforcement cage combined hanging method.
Background technology
Major diameter, traditional hanging method of overlength steel reinforcement cage be by steel reinforcement cage colligation, be welded after be segmented by crane
Near steel reinforcement cage handling to stake position, then welded, be finally slowly put into rotary digging stake holes.Traditional hanging method is present
Problems with：When steel reinforcement cage is lifted by crane, steel reinforcement cage unbalance stress, it is easy to fall apart, deform has a strong impact on rotary digging stake to crane
Hole quality；Major diameter, overlength steel reinforcement cage deadweight it is excessive, the entrance of stake holes is normally on high-order ground, crane need elongation
Brachium lifts the steel reinforcement cage positioned at low level ground, is easily overturned in hoisting process, there is potential safety hazard；Lifting adjustment when
Between it is more long, can increase that rotary digging stake holes bottom hole sediment is thickening, collapse hole risk.
The content of the invention
The technical problems to be solved by the invention are：A kind of steel reinforcement cage combined hanging method is provided, is capable of achieving major diameter, is surpassed
Steel reinforcement cage long it is accurate, install lifting in place, steel reinforcement cage will not fall apart, deform in hoisting process, it is ensured that rotary digging stake holes into
Hole quality.
It is to solve above-mentioned technical problem the technical solution adopted in the present invention：A kind of steel reinforcement cage combined hanging method, bag
Include following steps：
A, the first lifting rope of port connection in steel reinforcement cage, the second lifting rope is connected in the stage casing of steel reinforcement cage and lower end, above-mentioned
Junction all sets reinforced steel；
B, the first crane are located at high-order ground, and the second crane is located at low level ground, steel reinforcement cage is lain on low level ground,
First crane connects the first lifting rope, and the second crane connects the second lifting rope；
C, the first crane and the second crane lift by crane steel reinforcement cage simultaneously, first by the first lifting rope and the second lifting rope prestretching during lifting
Tightly；
D, the first crane and the second crane are combined and steel reinforcement cage is hung into ground turn to stake holes, and the second crane is gradually reduced lifting
Power departs from steel reinforcement cage up to the second lifting rope, and steel reinforcement cage progressivelyes reach erectility；
E, when the second lifting rope depart from steel reinforcement cage after, the first crane increase lifting power simultaneously change brachium by steel reinforcement cage align piles
Hole, finally enters in stake holes steel reinforcement cage handling.
The beneficial effects of the invention are as follows：Lifting is combined to steel reinforcement cage using two cranes, it is ensured that steel reinforcement cage is from lifting
When horizontality to uniform force during erectility, will not be fallen apart because of unbalance stress, deformed, be also avoided that
Crane topples；The present invention can disposably lift steel reinforcement cage in place, it is not necessary to carry out segmental hoisting, save lifting step
Suddenly, and the lifting time is shortened, it is ensured that rotary digging stake holes hole quality.

Specific embodiment
For the ease of understanding the present invention, the present invention is further detailed below in conjunction with the accompanying drawings.
A kind of steel reinforcement cage combined hanging method of the present invention, comprises the following steps：
A, as shown in figure 1, steel reinforcement cage 1 port connect the first lifting rope 2, two terminations of the first lifting rope 2 are connected to
The two ends of the diameter of the port of steel reinforcement cage 1, the second lifting rope 3, two ends of the second lifting rope 3 are connected in the stage casing of steel reinforcement cage 1 and lower end
Head is connected to the stage casing and lower end of steel reinforcement cage 1, because the junction of lifting rope and steel reinforcement cage 1 is stress stress point, each connection
Place is easiest to fall apart, therefore all sets reinforced steel in above-mentioned junction；
B, the first crane 4 are located at high-order ground, and the second crane 5 is located at low level ground, steel reinforcement cage 1 is lain in into low level ground
On, the first crane 4 connects the first lifting rope 2, and the second crane 5 connects the second lifting rope 3；
C, as shown in Fig. 2 the first crane 4 and the second crane 5 lift by crane steel reinforcement cage simultaneously, first by the He of the first lifting rope 2 during lifting
The pretension of second lifting rope 3, during lifting, the steel reinforcement cage 1 of the first crane 4 and the second crane 5 all to keeping flat applies upward pulling force, by
The stage casing and lower end of steel reinforcement cage 1 are connected in the second lifting rope 3, then the middle hypomere of steel reinforcement cage 1 is subject to the pulling force of the second crane 5, the
One lifting rope 2 is connected to the port of steel reinforcement cage 1, then when lifting by crane, the middle epimere of steel reinforcement cage 1 is subject to the pulling force of the first crane 4, therefore steel
Muscle cage 1 accepts uniform in lifting, keeps horizontality, will not fall apart, deform；
D, as shown in figure 3, the first crane 4 and the second crane 5 combine by steel reinforcement cage hang ground turn to stake holes, the second crane
5 are gradually reduced lifting power up to the second lifting rope 3 departs from steel reinforcement cage, when the second crane 5 is gradually reduced lifting power, steel reinforcement cage 1
Suffered tension variations, the suffered pulling force from the second crane 5 of middle hypomere reduces, and the suffered pulling force from the first crane 4 in port is protected
Hold constant, then steel reinforcement cage 1 is inclined gradually downward, as the pulling force that the second crane 5 is provided is less and less, steel reinforcement cage 1 is progressivelyed reach
Erectility, now steel reinforcement cage 1 be no longer influenced by the pulling force from the second crane 5, the second lifting rope 3 also because of no pulling force effect from
Come off on steel reinforcement cage 1；
E, when the second lifting rope 3 depart from steel reinforcement cage after, the first crane 4 increase lifting power simultaneously change brachium by steel reinforcement cage align piles
Hole, finally enters in stake holes steel reinforcement cage handling；Concrete cover finally is fixed outside stake holes entrance, concrete cast is carried out
.
