For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of concrete structure of the impression steel wire that mixes, comprise concrete and reinforcing rib, and be doped with many impression steel wires in the concrete and be mixed into the doping layer of concrete;
Described impression steel wire length 18-30mm, width 2-4mm, thickness 0.5-1.5mm, depth of cup 3mm.
Described doping layer of concrete is divided into multilayer according to the proportioning difference of doping impression steel wire;
One of them proportioning is that impression steel wire and concrete percentage by weight are 1-5%;
Wherein another proportioning is that impression steel wire and concrete percentage by weight are 10-20%.
Described many reinforcing ribs are crisscross to be welded to form multilayer laminated structure, the end of each reinforcing rib and housing welding, the position of described reinforcing rib and housing welding is near the bottom of housing, and having at least in length and breadth, the reinforcing rib of each one deck has the shape that arches upward in the middle part.
Described impression steel wire is provided with a plurality of impressions, and the width of Indentation position is than the wide 0.3-1mm of the width of other positions.
A kind of method for preparing the concrete structure of doping impression steel wire may further comprise the steps:
One, housing is placed in the mould, insert the 3rd doping layer of concrete, in this layer, impression steel wire and concrete percentage by weight are 1-5%;
Two, smash shake closely knit after, insert the second doping layer of concrete, in this layer, impression steel wire and concrete percentage by weight are 10-20%;
Three, smash shake closely knit after, insert the first doping layer of concrete, in this layer, impression steel wire and concrete percentage by weight are 1-5%;
Obtain the concrete structure that failure load surpasses the doping impression steel wire of 360KN by above-mentioned steps.
The concrete structure of the doping impression steel wire that the utility model provides by adopting above-mentioned shape and structure, has improved the failure load of concrete structure, and the failure load of the concrete manhole cover of diameter 800mm is the highest can to reach 945KN, cracking load 405 KN.And the highest ranking failure load of existing standard is 360 KN.Above-mentioned experimental data is provided by Suzhou concrete water mud product research institute.
Utility model people finds, the impression steel wire that mixes in the layer of concrete is not The more the better, although more impression steel wire makes strength increase, also increased the possibility that produces the crack, affect the outward appearance of concrete products, and increased the probability that the impression steel wire is corroded, therefore, the utility model has adopted at the less impression steel wire that mixes near the position of outer wall, at the more impression steel wire that mixes near inner position, obtain thus the balance of performance, and saved steel approximately 25%.
Special impression steel wire, lowered difficulty of processing, adopt mould with the steel wire embossing, and mould is applied larger pressure, make under pressure, the distortion that the impression position is pressed by mould, width increases, under the prerequisite that does not increase too many difficulty of processing, further improved impression steel wire and concrete adhesion, or be called bond stress thus.
