Description

But reuse's reinforcing bar split heads for building floor

Technical Field

The utility model relates to a construction technical field, in particular to but reuse's reinforcing bar split heads for building floor.

Background

In the construction of building construction engineering, in order to ensure the accuracy of the position of the upper layer steel bar or the hogging moment steel bar of the cast-in-situ floor slab, a steel bar split heads is usually adopted between the upper layer steel bar and the lower layer steel bar of the cast-in-situ floor slab to support and fix the upper layer steel bar. In the cast-in-place reinforced concrete floor slab component, the hogging moment reinforcing steel bars are used as main stress reinforcing steel bars, whether the accuracy of the position of the component can be ensured during construction or not can be ensured, and the bearing capacity and the durability of the component can be directly influenced. At present, construction units generally adopt simple and easy reinforcing steel bar split heads made of reinforcing steel bar leftovers in order to save construction cost, although the fixing of upper reinforcing steel bars can also be realized, because the reinforcing steel bar split heads are poured into the concrete together with the structural steel bars, cyclic utilization can not be realized, and the production cost is actually increased.

In order to save construction cost, a plurality of reusable steel bar split heads are available, namely, the split heads can be extracted before the cast concrete is completely solidified, but the split heads common in the current engineering have some unsatisfactory defects, for example, patent CN 103422622 a discloses a height-adjustable reusable steel bar split head, which comprises a lifting hook, a lifting mechanism and a bracket, wherein the bracket comprises a tray with a central through hole, and the lower part of the tray is hinged with three legs in a triangular arrangement; the lifting mechanism is a screw lifting mechanism, a handle sleeve fixedly connected with the nut into a whole is sleeved on a screw of the screw lifting mechanism, the screw lifting mechanism is inserted into the screw, the central through hole of the tray is integrally assembled on the bracket, and a lifting hook for lifting the steel bar is welded at the lower end of the screw.

Above-mentioned patent simple structure, reuse's function has obviously been realized, but also there are a lot of problems, if when taking out the split heads, operating personnel need let the certain angle of split heads slope just can ensure the support that the reinforcing bar breaks away from the lifting hook, because the split heads is located in the middle of the concrete, it has been very hard directly to take out, it is just more difficult to take out the split heads after need slope earlier, the split heads of this structure can make peripheral concrete not hard up at the in-process that takes out, and can bring out a large amount of concrete, cause the floor quality to be difficult to guarantee, follow-up floating mends hole work load great.
