Description
Technical field
The present invention relates to a kind of construction method, be specially a kind of constructional column bar planting positioning construction method.
Background technology
When traditional constructional column bar planting is constructed, be to punch on the beams of concrete member of closely having constructed, then plantMuscle. Due to the three-dimensional steel muscles and bones frame systems such as principal rod, stirrup that gather in beam concrete component, while causing bar planting boring for dodgingFramework of steel reinforcement in the beam of having built, is offset serious construction quality problem ubiquity and produce constructional column reinforcement location,Through having formed the main mass defect in Constructional Col-umn Construction. As schematically shown in Figure 1, 2, position and the design attitude of bar planting are inconsistent,Cause like this flexural deformation of bar planting, affect the mechanical property of member integrated. Therefore, solve the construction method of this difficult problem non-Normal urgent.
Summary of the invention
The present invention, in order to solve the inaccurate problem in location existing in the construction of post reinforcing steel implant, provides a kind of constructional columnBar planting positioning construction method.
Technical scheme of the present invention is: a kind of constructional column bar planting positioning construction method, and in concrete beam reinforcing and template peaceAfter dress, prepare to carry out, before concreting, beam bottom board being cleared up, measure unwrapping wire, determine constructional column position, use chilli oilPaint is smeared location at beam bottom board, cast concrete, and form removal, according to the boring of red paint position, clear hole, injecting glue, bar planting, solidifies, protects,Check and accept.
Concrete steps are to install at concrete beam reinforcing and template, prepare to carry out before concreting, by template baseOn layer, clean out; Determine constructional column main reinforce position according to designing requirement and regulation and stipulation, and guarantee in bar planting depth boundsNo-reinforcing-bar and other members block; According to the position determining, the U-shaped reinforcing bar that uses width to make for the main muscle width of constructional column is determinedPosition mould, dips in red paint in the termination of orientation tool, smears location on beam bottom board, and the red anchor point of formation is mixed like thisSolidifying soil is built complete, and after form removal, red paint can form visual anchor point on beams of concrete bottom surface; Again according to visual anchor point positionPut and hole, hole depth meets bar planting requirement; Boring is cleared up, adopt behind the clear hole of compressed air, then be stained with third with absorbent cottonKetone is cleaned hole wall, and answers retaining hole inner drying; By glue kind join glue and to boring injecting glue; Adopt rustless reinforcing bar implant bore, rightReinforcing bar is rotated bonding in order to structure glue and the wall of a borehole, and the reinforcing bar of implantation does temporary fixed; After bar planting completes, according to bar plantingGlue type and environment temperature guarantee that planted reinforcing bar is cured at the appointed time, and setting up period is forbidden disturbance reinforcing bar; Structure glueAfter solidifying, the pull-out test that adopts instrument to carry out on-the-spot bar planting according to amount of inspection, to check the performance of bar planting, and wants by specificationAsk and carry out an acceptance inspection.
Compared with prior art, the key point of technical solution of the present invention is to install at concrete beam reinforcing and template,Preparation is carried out before concreting. Use U-shaped reinforcing bar jig according to constructional column main reinforce position at beam bottom board correspondence position, useRed paint is smeared location. Owing to being in concreting prelocalization, therefore can dodge out reinforcing bar in beam. Treat beam concrete bottom dieAfter dismounting, according to red paint position corresponding on the beam base concrete bar planting of holing, can ensure that a bar planting puts in place. Thereby keep awayExempt from the direction blindness in traditional bar planting construction, effectively improved efficiency of construction and construction quality.

Detailed description of the invention
As Fig. 3,4,5 illustrate, a kind of constructional column bar planting positioning construction method, step is as follows:
1, install at concrete beam reinforcing 7,5 and side template 6,4, prepare to carry out before concreting. For ensureing matterAmount, will clean out in basic unit, do not wait and have water stain grade of greasy dirt to hinder the spot of painting brushing, and beam bottom board 9 should be smooth, must notDamaged cracking.
2, measure unwrapping wire, determine constructional column position
Determine constructional column main reinforce position according to designing requirement and regulation and stipulation, can within the scope of tolerance, suitably avoidThe position of beam main tendon. And guarantee that the interior no-reinforcing-bar of bar planting depth bounds and other members block.
3, smear location with red paint at beam bottom board
According to the position determining, use long 1.5m left and right, width is the U-shaped reinforcing bar location that the main muscle width of constructional column is madeMould, this mould structure is as Fig. 4. Dip in appropriate red paint in termination, then insert in template, on beam bottom board, smear location. ShapeThe anchor point 8 becoming is round point shape, and diameter is advisable for " drilling diameter "+5mm. This mould structure is simple, can pass slow setting Tu LiangThe bar-mat reinforcement that reinforcing bar forms.
4, casting concrete.
5, form removal, after form removal, red paint can be bonded at and on beams of concrete 12 bottom surfaces, form anchor point 13 at the bottom of beam, notes locationPoint is protected, and avoids colliding with.
6 hole according to red paint position
Hole according to anchor point 13 positions, boring should adopt electric hammer or air drill pore-forming, need ensure that hole is positioned at when pore-formingAnchor point center, and drill bit is vertical with soffit, without skew. Hole depth should meet bar planting requirement.
7 clear holes
Boring is cleared up, adopt behind the clear hole of compressed air, then be stained with acetone with absorbent cotton and clean hole wall, and answer retaining holeInner drying.
8 injecting glues
By glue kind join glue and to boring injecting glue, when injecting glue must get rid of boring in air, consumption with reinforcing bar implant after slightlyBe extruded as standard.
9 bar plantings
Adopt rustless reinforcing bar 11 implant bores, reinforcing bar is rotated to bonding in order to structure glue and the wall of a borehole, implantReinforcing bar do temporary fixed.
10 solidify, protect
After bar planting completes, guarantee that according to anchoring adhesive type and environment temperature planted reinforcing bar is cured within a certain period of time,Setting up period is forbidden disturbance reinforcing bar.
11 check and accept
After structure glue is solidified, adopt the instrument pull-out test that carries out on-the-spot bar planting according to amount of inspection, to check bar plantingPerformance, and carry out an acceptance inspection by code requirement.
