Bottom fold corner, the elongated muscle in middle part is positioned in the middle part of stirrup hanging portion, and with stirrup perpendicular contact, finally muscle elongated to bottom
With stirrup, the elongated muscle in middle part and stirrup carry out colligation.
3), require to classify reinforcing bar according to setting-out, be hoisted to scene；
4), Site Template makes:
4a), according to step 2) in reinforcing bar sample carry out installing template, template cavity and be wrapped in primary structure lintel and tie with secondary
Outside structure lintel, template butt seam cements with pressure sensitive adhesive double coated, it is to avoid gap；Template machines and makes primary structure lintel and secondary
The template of structure lintel is through, is an entire body；
4b), while installing template, being provided with thickness between the template outside secondary structure lintel and concrete walls is 1-
The soft isolation of 5cm, it is to avoid one-shot forming lintel and concrete walls connect as one structure；
5), on-the-spot colligation: by reinforcing bar completely colligation, to adjusting anchorage of stirrups part, keep the straight and mutual of reinforcing bar
Between distance.
6), checking and accepting, casting concrete in the template installed, the thickness controlling concrete cover is 1cm；
7), watering maintenance；
8), terminate construction, check and accept.
Step 2b) in, stirrup anchors into 1/6th of a length of total length of primary structure lintel, and described stirrup is straight
The one-level steel of footpath 6cm.
Described soft isolation is specially extruded sheet or template material, and its height does not anchors into primary structure with secondary structure lintel
The height of lintel sections is equal.
Having the beneficial effects that of the invention: the invention provides a kind of primary structure and secondary structure door opening mistake
Beam one-shot forming construction method, first carries out the construction of primary structure reinforcing bar beam, afterwards anchoring into by secondary structure stirrup, construction
The reinforcing bar part of secondary structure beam, makes template afterwards, molding after-pouring concrete, the present invention by above-mentioned construction method, two
Aggregated(particle) structure lintel is included in once construction, synchronization carries out with once constructing, and solves primary structure and splits with secondary structure contact position
The common quality defects such as seam, reduce precast lintel secondary working procedure, propelling construction progress.

Detailed description of the invention
Primary structure and secondary structure door opening lintel one-shot forming construction method, the steps include:
1) the reinforcing bar part construction of primary structure lintel 2, is carried out；
2), secondary structure lintel 1 reinforcing bar is carried out decompose setting-out:
2a), stirrup 1-2 setting-out construction is carried out: stirrup 1-2 is generally with the frame like structure of opening, and the stirrup 1-2 of opening part hangs down
Directly extend to the inside of frame；During construction, stirrup 1-2 is anchored in primary structure lintel 2 with the crotch at opening part two ends, and will
Hoop 1-2 colligation is on the reinforcing bar of primary structure lintel 2；
2b), the construction of long muscle: penetrating in stirrup 1-2 by elongated for bottom muscle 1-1 and middle part elongated muscle 1-3, wherein, bottom is elongated
Muscle 1-1 puts into stirrup 1-2 bottom fold corner, and middle part elongated muscle 1-3 is positioned in the middle part of stirrup 1-2 hanging portion, and with stirrup 1-2
Perpendicular contact, finally muscle 1-1 elongated to bottom and stirrup 1-2, middle part elongated muscle 1-3 and stirrup 1-2 carry out colligation.
3), require to classify reinforcing bar according to setting-out, be hoisted to scene；
4), Site Template makes:
4a), according to step 2) in reinforcing bar sample carry out installing template 4, template 4 cavity and be wrapped in primary structure lintel 2 and two
Aggregated(particle) structure lintel 1 is outside, and template butt seam cements with pressure sensitive adhesive double coated, it is to avoid gap；Template machines and makes primary structure lintel 2
Through with the template of secondary structure lintel 1, it is an entire body；
4b), while installing template, being provided with thickness between template 4 and the concrete walls outside secondary structure lintel 1 is
The soft isolation 3 of 1-5cm, it is to avoid one-shot forming lintel and concrete walls connect as one structure；
5), on-the-spot colligation: by reinforcing bar completely colligation, to adjusting stirrup 1-2 anchorage part, keep the straight and phase of reinforcing bar
Distance between Hu.
6), checking and accepting, casting concrete in the template installed, the thickness controlling concrete cover 4 is 1cm；
7), watering maintenance；
8), terminate construction, check and accept.
Step 2b) in, stirrup 1-2 anchors into 1/6th of a length of total length of primary structure lintel, described stirrup
1-2 is the one-level steel of diameter 6cm.
Described soft isolation 3 is specially extruded sheet or template material, and its height does not anchors into secondary structure lintel 1 once to be tied
The height of structure lintel 2 part is equal, and preferred thickness is 3cm.
Described stirrup 1-2, bottom elongated muscle 1-1 and middle part elongated muscle 1-3 are one-level steel, its middle and lower part elongated muscle 1-
A diameter of 12mm of 1 and middle part elongated muscle 1-3；The a diameter of 6mm of stirrup 1-2, arrangement pitch is 20cm；When secondary structure lintel 1
When not anchoring into the Partial Height of primary structure lintel 2 less than 20cm, the elongated muscle 1-3 in middle part can not be applied.
Fig. 4 show prior art constructing structure schematic diagram, needs precast lintel in advance, and precast lintel needs the most in advance
Prefabricated, and need to build masonry I in advance by laying bricks or stones, and precast lintel is placed on the masonry I built by laying bricks or stones, then the masonry II later stage is built
Build, precast lintel is filled with primary structure beam space.Construction procedure is loaded down with trivial details and the duration is longer, wastes manpower thing simultaneously
Power.
