Technical Field

The utility model relates to the technical field of steel bar pouring, in particular to a steel bar spacing device, a steel bar layer and a pouring mold.

Background

The currently adopted steel bar spacer mainly comprises a plastic cushion block, a mortar cushion block, a finished product long-strip-shaped steel bar stirrup and a self-made Z-shaped steel bar stirrup. The spacers are developed after years of practice in the construction industry, are convenient to purchase or manufacture, are simple to install, have mature processes and have high field acceptance. But also have more shortcoming, the finished product distance piece of purchase all is fixed dimension, and with wrong and reinforcing bar protective layer control inaccurate when different floor thickness, the cushion is emptyd easily, and finished product metal stirrup bottom is direct and template contact, appears the phenomenon of becoming rusty easily after the form removal, has not been suitable for present floor bottom and exempts from the technological trend of whitewashing and probably brings adverse effect for concrete structure's durability. The Z-shaped steel bar spacer manufactured on site only can bear point-shaped load, the position without the spacer is easy to shift, and the integral state of the floor slab steel bar is difficult to control. More importantly, the existing traditional steel bar spacer comprises an arc-shaped steel bar stirrup connecting structure with similar processes, only can separate upper and lower steel bar frameworks, and the thickness of the steel bar protective layer and the structural plate cannot be accurately controlled. The function is single, the cost performance is low, and the aim of directly controlling the plate thickness cannot be achieved.

As disclosed in patent document CN205917998U, an arc-shaped steel bar split heads connection structure is disclosed, which comprises an upper layer of steel bars, a lower layer of steel bars, and split heads supported therebetween, wherein the split heads are in the form of trusses and comprise upper horizontal stay bars, lower horizontal stay bars, and a set of web members, the upper side of the upper horizontal stay bars is supported on the lower side of the upper layer of steel bars, and the lower side of the lower horizontal stay bars is supported on the upper set of web members of the lower layer of steel bars; the split heads in this scheme can play better supporting role to upper and lower layer reinforcing bar, but its function is single to a certain extent, if upper reinforcing bar pressurized is great, the support stability of split heads is still relatively poor.
