Description

Simple limiting split heads for supporting upper and lower layers of reinforcing steel bars

Technical Field

The utility model particularly relates to a building engineering technical field especially relates to a simple and easy spacing split heads of lower floor reinforcing bar on supporting.

Background

The reinforcing steel bar split heads are used between the upper and lower reinforcing steel bar meshes and play a role in fixedly supporting the upper reinforcing steel bar mesh, so that the upper reinforcing steel bar mesh can bear loads caused by various construction activities, and the upper reinforcing steel bar mesh is ensured to have enough concrete protective layer thickness, so that the protective layer thickness is in a range specified by a specification. When the reinforced concrete slab is constructed, the split heads are indispensable construction auxiliary members in the measure reinforcing steel bars. At present, the general split heads have the shapes of 'n' -shaped, 'herringbone' and triangular shapes, binding or welding fixation needs to be carried out on the steel bar mesh, if the steel bar split heads are fixed in a welding mode, the workload of constructors is large, time and labor are wasted, the construction period is influenced, meanwhile, the construction cost is high, if the steel bar split heads are fixed in a binding mode, after loads are applied to the surface of the upper layer of steel bar mesh, the steel bar split heads are prone to being deformed or binding wires between the steel bar mesh fall off, the thickness of the protective layers of the upper layer of steel bar mesh and the lower layer of steel bar mesh cannot reach the range specified by standards, and the bearing capacity of the reinforced concrete slab cannot reach the design value requirement.

In the prior art, the publication numbers are: the patent document "CN 210342446U" discloses an adjustable steel bar split heads for building construction. It includes and can carry out the fixed part of support fixing to the reinforcing bar according to reinforcing bar diameter size, left branch leg and right branch leg, the fixed part includes the recess that is equipped with at the fixed part top along the length direction of fixed part, length direction along the recess is equipped with a spout in the bottom of recess, be equipped with the slider with spout looks adaptation on the spout, the slider passes through lock nut and spout fastening locking, the slider set up to the arcwall face that suits with the reinforcing bar with a side of reinforcing bar contact, be equipped with the fin on the arcwall face, below at the fixed part is equipped with supporting component, supporting component includes gusset plate and stand. However, the split heads in the above patent technologies need to be bent during the manufacturing process, the processing technology is complex, and is difficult to be widely popularized and applied in the construction site, the upper and lower layers of steel bars are supported by the separate columns, the stability is poor, and when concrete is poured, the split heads are easily deformed by the impact of the concrete, so that the engineering construction quality is affected.
