Description

Auxiliary hoisting structure for building construction

Technical Field

The utility model relates to a construction technical field, especially a hoisting structure is assisted in construction.

Background

The steel reinforcement cage includes that main muscle, stiffening hoop and spiral helicine stirrup constitute, and a spiral helicine stirrup welding is provided with stiffening hoop in the circle on many main muscle constitute cylindrical outer lane, by a plurality of rings hoop interval welded fastening at main muscle inner circle, should stiffen the effect that the hoop played the support steel reinforcement cage.

At present, when a reinforcement cage is hoisted, a stiffening hoop is generally hung by a lifting hook directly for hoisting, and the hoisting mode mainly has two problems, namely the reinforcement cage is not vertical after being hoisted, so that the reinforcement cage is not convenient to place in a foundation pit; secondly, the reinforcing cage stiffening hoops are easy to be detached from the welding by the single-side crane, so that the strength and the performance of the reinforcing cage are influenced. Therefore, a lifting appliance specially for lifting the reinforcement cage is needed at present.

Disclosure of Invention

To the situation, for solving the problem that exists among the prior art, the utility model aims at providing a hoisting structure is assisted in construction, out of plumb and the unbalanced problem of atress when can effectively solving the steel reinforcement cage hoist and mount.

The technical scheme includes that the device comprises a circular ring, a plurality of vertical guide rods are evenly distributed on the circumference of the circular ring, the guide rods can move up and down along the circular ring, a fixed disc is fixed at the lower ends of the guide rods, and a protruding block is arranged in the middle of the fixed disc; a plurality of radial supporting rods are arranged on the circular ring, and the supporting rods can reciprocate along the radial direction of the circular ring and reset inwards; after the supporting rod moves outwards, the outer end of the supporting rod can extend out of the outer edge surface of the circular ring; the convex block can block the support rod from resetting inwards after moving upwards.

The utility model discloses the simple operation can realize vertical lifting by crane, lifts by crane steadily to the unhook is convenient.

Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.

As shown in fig. 1 to 4, the utility model comprises a circular ring 1, a plurality of vertical guide rods 2 are evenly distributed on the circular ring 1, the guide rods 2 can move up and down along the circular ring 1, a fixed disc 3 is fixed at the lower ends of the guide rods 2, and a convex block 4 is arranged in the middle of the fixed disc 3; a plurality of radial supporting rods 5 are arranged on the circular ring 1, and the supporting rods 5 can reciprocate along the radial direction of the circular ring 1 and reset inwards; after the supporting rod 5 moves outwards, the outer end of the supporting rod 5 can extend out of the outer edge surface of the circular ring 1; after the convex block 4 moves upwards, the support rod 5 can be blocked to reset inwards.

In order to facilitate hoisting, the upper end of each guide rod 2 is provided with a hoisting hole 6, and the hoisting holes 6 of the guide rods 2 are connected through a steel wire rope 7.

In order to realize the reciprocating movement and inward reset of the supporting rods 5, a boss 8 is fixed at the inner end of each supporting rod 5, and a pressure spring 9 positioned between the boss 8 and the circular ring 1 is sleeved on each supporting rod 5.

In order to avoid the struts 5 from being completely contracted into the inner part of the ring 1, a convex point 10 is fixedly arranged on the lower side surface of the outer end of each strut 5.

For better clamping the stiffening hoops of the reinforcement cage, a groove 11 is formed in the upper side face of the outer end of each supporting rod 5.

The utility model discloses during the use, at first place this device in steel reinforcement cage's inside, later through stirring every branch 5, make a plurality of branches 5 all stretch out ring 1, then pull guide arm 2 for ring 1 is to lifting, make the inside that ring 1 can be arranged in to protruding piece 4 on the fixed disk 3 to make protruding piece 4 block branch 5 and reset. The grooves 11 on the struts 5 are then positioned to correspond to the stiffening hoops of the reinforcement cage, so that the struts 5 support different positions of the same stiffening hoop. And finally, the upper ends of the guide rods 2 are connected with the lifting hooks through steel wire ropes 7. The hoisting can be performed.

In the hoisting process, the plurality of support rods 5 on the circular ring 1 support the stiffening hoops of the reinforcement cage at multiple points, so that the lifting hooks can be positioned at the positions corresponding to the axis of the reinforcement cage, and the reinforcement cage can be kept in a vertical state after being hoisted; avoid the slope, be convenient for place inside the corresponding foundation ditch under the steel reinforcement cage.

Because the multi-point support is adopted, the gravity of the reinforcement cage can be uniformly distributed on the device, and the desoldering caused by the stress of a single point of the stiffening hoop is avoided.

After the steel reinforcement cage is placed, the device needs to be separated; the concrete operation is that after the lower part of the reinforcement cage, the lifting hook is continuously lowered, at the moment, the supporting rods 5 can be blocked by the spiral stirrups, the fixed disc 3 is positioned at the central position of the reinforcement cage and cannot be blocked, so that the fixed disc 3 can descend, the protruding blocks 4 are separated from the circular ring 1, at the moment, the plurality of supporting rods 5 can be reset inwards under the action of the pressure spring 9, the supporting rods 5 are contracted into the circular ring 1, and meanwhile, because the lower side surface of the outer end of the supporting rod 5 is provided with the salient points 10, the supporting rods 5 cannot be completely contracted, but are separated from the support of the stiffening hoops; thus, by now pulling the entire device up, the bumps 4 will abut the inner ends of the plurality of struts 5, raising the entire device.

The device is provided with the circular ring 1 and the supporting rod 5, utilizes the flexibility of the supporting rod 5 to insert into a gap of the reinforcement cage, and utilizes the supporting rod 5 to support the stiffening hoop of the reinforcement cage, thereby playing the effect of lifting the stiffening hoop hooked with the reinforcement cage; meanwhile, after the strut 5 is contracted into the circular ring 1, the strut 5 does not correspond to the stiffening hoops, so that the whole circular ring 1 can be lifted from the central position of the reinforcement cage.

The device has the advantages that the guide rod 2 capable of moving up and down, the fixed disc 3 and the protruding blocks 4 are arranged, the protruding blocks 4 are utilized to limit the supporting rods 5, and in the lifting process, the protruding blocks 4 are always positioned in the circular ring 1, so that the stability of lifting is guaranteed; when the lifting is not needed, the supporting rod 5 can automatically contract after the convex block 4 descends, and can be lifted again, so that the automatic unhooking function can be realized.
