Abstract
The invention discloses a pouring method for a reinforced concrete protective layer of an iron tower foundation. The pouring method comprises the following steps: firstly building a reinforced structure at a position where the iron tower foundation is prebuilt; welding two supporting ribs with length of 5 cm on the two sides or two ends of each edge of rectangular stirrups in the horizontal direction respectively, wherein the supporting ribs are perpendicular to a corresponding edge of each rectangular stirrup, and the space between upper and lower groups of adjacent supporting ribs is 100-150 mm; fixedly arranging four formworks on the outer side of the rectangular stirrups and bundling together to form a closed pouring space, wherein the inner surface of each formwork is abutted against the corresponding supporting rib; pouring concrete in the pouring space defined by the formworks by using a concrete pouring vehicle, and closing the top end with an upper cover after the pouring space is filled up; disassembling the formworks after three days, wrapping with plastic cloth and placing in a pit for curing to finish operation. The method can guarantee that the thickness of protective layer of the reinforced concrete is uniform and reaches 5 cm to prevent oxidation of the reinforcements and prolong the life cycle of the iron tower foundation.
Description
Technical field
The present invention relates to a kind of casting method of iron tower foundation reinforced concrete protective layer.
Background technology
Reinforced concrete protective layer, be protection reinforcing bar not by corrosion, be also the guarantee of iron tower foundation life cycle, technical standard require institute placing of concrete Hou Du Wei≤5cm.Because when concrete baffle plate is fixed, there is no fixed standard in, probably due to fixing shakiness, cause concrete baffle plate crooked, or reinforcing bar distortion does not keep vertical state.During placing of concrete, it is in uneven thickness, local thickness less than 5cm, cause reinforced concrete protective layer to be not enough to prevent reinforcing bar to be oxidized, iron tower foundation life cycle shortened.
Summary of the invention
The present invention is the deficiency that will solve prior art existence, provides a kind of casting method of iron tower foundation reinforced concrete protective layer, ensures that Minimum Concrete Protective Coating Thickness is even, reach 5cm, prevents reinforcing bar to be oxidized, extend the life cycle of iron tower foundation.
A casting method for iron tower foundation reinforced concrete protective layer, its step is as follows:
1, first build the bar construction be made up of the reinforcing bar vertically placed, rectangle hoop building iron tower foundation position in advance, described reinforcing bar and rectangle hoop are linked together by iron wire binding;
2, welding two length respectively in the horizontal direction in the both sides on each limit of rectangle hoop or two ends is the brace rod of 5cm, and described brace rod is perpendicular to the corresponding edge of rectangle hoop; The spacing of two groups of neighbouring brace rods is 100mm-150mm;
3, outside rectangle hoop, set firmly four pieces of templates and tie, form the pouring space closed, every block template inner surface leans on the brace rod of correspondence;
4, in utilize concrete mobile to be filled in by concrete casting pouring space that template surrounds, rear top end cover upper cover plate is filled;
5, after 3 days, template of dismantling, with Polypropylence Sheet parcel, puts into heatable adobe sleeping platform and carries out health, fulfil assignment.
Beneficial effect of the present invention: operation is simple; under the prerequisite substantially not increasing cost; by the both sides on each limit at rectangle hoop or two ends, brace rod is set; template is made to lean on brace rod; solve because of template tilt or reinforcing bar be out of shape cause Minimum Concrete Protective Coating Thickness inequality, less than the problem of 5cm; make reinforced concrete protective layer reach design standard, reduce the reinforcing bar oxidation rate of steel tower pedestal, extend steel tower pedestal life cycle.

Fig. 1 is structural representation of the present invention;
Fig. 2 is the top view of Fig. 1.
In figure: 1-reinforcing bar, 2-rectangle hoop, 3-brace rod, 4-template.
Detailed description of the invention
As shown in the figure, the casting method of this iron tower foundation reinforced concrete protective layer, step is as follows:
1, first build the bar construction be made up of the reinforcing bar 1 vertically placed, rectangle hoop 2 building iron tower foundation position in advance, described reinforcing bar 1 and rectangle hoop 2 are linked together by iron wire binding;
2, weld the brace rod 3 that two length are 5cm respectively in the horizontal direction in the both sides on each limit of rectangle hoop 2 or two ends, described brace rod 3 is perpendicular to the corresponding edge of rectangle hoop 2; The spacing of two groups of neighbouring brace rods 3 is 120mm(or 140mm);
3, outside rectangle hoop 2, set firmly four pieces of templates 4 and tie, form the pouring space closed, every block template inner surface leans on the brace rod of correspondence;
4, concrete casting is filled in pouring space that template 4 surrounds, fills rear top end cover upper cover plate;
5, after 3 days, template 4 of dismantling, with Polypropylence Sheet parcel, puts into heatable adobe sleeping platform and carries out health, fulfil assignment.
