Abstract
The invention discloses a steel reinforcement cage lifting structure. Specifically, reinforcement hoops are welded in the inner ring of a steel reinforcement cage main reinforcement ring. Three wire ropes are sleeved on the lateral of the steel reinforcement cage at lifting point A, lifting point B and lifting point C respectively and tighten up the steel reinforcement cage. Two ends of the wire ropes are provided with shrink-rings, wherein, the shrink-ring at one end passes through the shrink-ring at the other end and is hung on a lifting hook, while the shrink-ring at the other end is locked together with reinforcement hoops through a shackle. According to the invention, reinforcement hoops are welded in the inner ring of a steel reinforcement cage main reinforcement ring, thus, the wire ropes tighten up in the process of lifting, and the inward side pressure of the wire ropes is borne by the reinforcement hoops, while the main reinforcement is not subjected to force. Therefore, an accident that the main reinforcement breaks away from the reinforcement hoops as a result of poor welding quality of the reinforcement hoops and the main reinforcement can be avoided.
Description
Technical field
The present invention relates to building construction technology, relate in particular to steel reinforcement cage.
Background technology
Sleeve pipe interlock stake is when install reinforcing cage, if the method that adopts two joint steel reinforcement cages to lift by crane together generally adopts the lifting of three suspension centres as shown in Figure 1, A, B, C three suspension centres lay respectively at steel reinforcement cage left side central portion and right side, at this moment the length of steel reinforcement cage reaches more than 18 meters, weight surpasses 3 tons, in the lifting process, when steel reinforcement cage when vertical, main stress point is suspension centre C, suspension centre A and B do not stress substantially, and therefore, the welding quality of suspension centre C place reinforced rib is directly connected to reinforcing bar cage hoisting safety.On the standard position of strengthening hoop is not had clear and definite requirement, in general, strengthening hoop 1 is to be welded on main muscle ring 2 outsides that main muscle is formed, but like this in the reinforcement cage hoisting process, in case the Heave Here is stressed, steel rope 3 tightens up, and main muscle will be subjected to the inside lateral pressure of steel rope, especially the lifting coda, steel reinforcement cage is near vertical, and at this moment the only remaining suspension centre C of stress point if strengthen hoop and main muscle not prison welding, cause easily and strengthen hoop and main muscle disengaging, safety misadventure takes place.
Summary of the invention
Technical matters to be solved by this invention just provides a kind of reinforcement cage hoisting structure, and is simple in structure, safe and reliable.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of reinforcement cage hoisting structure, it is characterized in that: be welded on steel reinforcement cage master muscle ring inner ring, three steel ropes are sheathed on the steel reinforcement cage outside and steel reinforcement cage are tightened up at suspension centre A, suspension centre B and suspension centre C respectively.
As preferably, described steel rope two ends are provided with the collar, and wherein an end collar passes the other end collar and hangs on the suspension hook, the other end collar by shackle with strengthen hoop and lock together.
The present invention will be welded on steel reinforcement cage master muscle ring inner ring, three steel ropes are respectively at suspension centre A, suspension centre B and suspension centre C are sheathed on the steel reinforcement cage outside and steel reinforcement cage are tightened up, like this, during lifting, steel rope tightens up, its inside side pressure is born by strengthening hoop, main muscle does not stress, and so not only can avoid the Yin Fashengyin reinforcement to bind round bad with the welding quality of main muscle and accident that cause main muscle disengaging reinforcement to bind round, and, along with tightening up of steel rope, it is big that the bond stress of suspension centre place steel rope and steel reinforcement cage also becomes thereupon, and simultaneously, suspension centre place steel rope is connected with the reinforcement hoop by shackle, avoid steel rope along the steel reinforcement cage longitudinal sliding motion, guaranteed lifting safety.
Description of drawings
Below in conjunction with the drawings and specific embodiments the present invention is further described:
Fig. 1 is three a suspension centres lifting steel reinforcement cage structural representation;
Fig. 2 is the reinforcement cage hoisting structural representation;
Fig. 3 is the steel cord ends structural representation.
The specific embodiment
As shown in Figure 1 to Figure 3, be the embodiment of a kind of reinforcement cage hoisting structure of the present invention, some circles are strengthened hoop 1 and are welded on steel reinforcement cage master muscle ring 2 inner rings, and three steel ropes 3 are sheathed on the steel reinforcement cage outside and steel reinforcement cage is tightened up at suspension centre A, suspension centre B and suspension centre C respectively.Described steel rope two ends are provided with the collar 6, and wherein an end collar passes the other end collar and hangs on the suspension hook 5, and the other end collar locks together by shackle 4 and reinforcement hoop.
Claims (2)
1. reinforcement cage hoisting structure is characterized in that: some circles are strengthened hoop (1) and are welded on steel reinforcement cage master muscle ring (2) inner ring, and three steel ropes (3) are sheathed on the steel reinforcement cage outside and steel reinforcement cage is tightened up at suspension centre A, suspension centre B and suspension centre C respectively.
2. a kind of reinforcement cage hoisting structure according to claim 1, it is characterized in that: described steel rope two ends are provided with the collar (6), wherein an end collar passes the other end collar and hangs on the suspension hook (5), and the other end collar locks together by shackle (4) and reinforcement hoop (1).
