The specific embodiment
For the benefit of the understanding to structure of the present invention, describes below in conjunction with drawings and Examples.
Shown in Fig. 1, the invention provides a kind of reserved anchoring construction method of shear wall inner panel reinforcing bar, after having taken into full account the globality and requirement of strength of structure, adopt the mode of shear wall pre-buried " beard muscle ".And, vertical structure and horizontal structure are separated to construction, coordinate in addition Core Walls Structure creeping formwork to climb continuously, to accelerate efficiency of construction and to improve structural integrity intensity.
It should be noted that, some length calculation method applying in the method all should belong to conventional computational methods in existing shear force wall reinforcing steel bar construction, therefore, at this, does not add to repeat.
Actual job site, can implement by the step shown in successively in Fig. 1:
First, in conjunction with Fig. 1 and Fig. 2, carry out S1, the embedded bar 1 that intercepting consists of anchoring section and revealed section, specific practice is:
First select HPB300 grade reinforcing steel as embedded bar 1, the diameter of HPB300 grade reinforcing steel generally all adopts and is greater than rank of floor bar.For example, when the bar diameter of floor is 10mm, pre-buried HPB300 grade reinforcing steel diameter is got 12mm and is advisable.
After the selection of embedded bar 1 determines, according to the diameter of embedded bar 1, determine the length D1 of revealed section, and the concrete strength of building according to shear wall calculates the length D2 of anchoring section, to obtain the intercepted length of whole embedded bar 1.Wherein, the length D1 of revealed section requires to be not less than 20 times of embedded bar diameter; Meanwhile, after obtaining actual concrete strength numerical value, by existing anchoring section design formulas, (formula principle is not added to repeat at this, in theory, concrete strength is higher, and anchoring section length D2 just can be relatively smaller), to calculate the length D2 of anchoring section.
Next, as shown in Figure 2, at first take revealed section and anchoring section as boundary, by whole embedded bar 1 bending, then carries out S2, and the anchoring section of many embedded bars 1 is pre-buried to shear wall 2, and manifest the revealed section of embedded bar 1.
In addition, what need additional description is, because the length D2 of anchoring section is that intensity according to shear wall institute concreting determines, at whole embedded bar 1 after bending for the first time, may run into also relatively low situation of thinner and its concrete strength requirement of shear wall thickness requirement, thereby cause the tail end of anchoring section to stretch out from the opposite side of shear wall.Now, just need to be first that the tail end of anchoring section is again crooked, then the anchoring section after bending is pre-buried to shear wall 2, with the phenomenon of avoiding the tail end of anchoring section surprisingly to stretch out.
Afterwards, as shown in Figure 3, every crooked embedded bar 1 just consists of revealed section 10 and anchoring section 12.Wherein, require revealed section 10 and anchoring section 12 to keep vertical as far as possible, so that revealed section 10 can fit in the external surface of shear wall 2 as far as possible, and, revealed section 10 need be extended by the length direction along shear wall 2.So arrange, on the one hand, can be convenient to formwork for placing and shear wall 2 laminatings, on the other hand, be also convenient to cover isolation strip 3 at revealed section 10.
Then, in conjunction with Fig. 1 and Fig. 4, carry out S3, on revealed section 10, cover isolation strip 3 and fixed.In the present embodiment, select area spongiosa as isolation strip 3, and adopt colligation silk that area spongiosa and shear wall 2 colligations is firm, to guarantee that sponge there will not be when the concreting, come off.
Then, in conjunction with Fig. 4 and Fig. 5, carry out S4, matched moulds is also built shear wall 2, so that forms concrete vertical structure.After building, curing concrete vertical structure, until reach after form removal requirement, then stripping.
Finally, in conjunction with Fig. 6 and Fig. 7, carry out S5, remove isolation strip 3, by horizontal reinforcement 3, horizontal structure is installed, its specific practice is:
First remove sponge, revealed section 10 will be revealed in outside concrete naturally.Can be further to the reinforcing bar of exposed parts, carry out that concrete is whole picks work around, smooth so that the concrete of revealed section 10 peripheries keeps.Again that revealed section 10 is stretching along the thickness direction of shear wall 2, thus revealed section 10 can vertically extend outside shear wall, so far, the slab form of horizontal structure just can be installed.Can be on slab form colligation horizontal reinforcement, adopt one side welding mode by horizontal reinforcement and revealed section 10 welding, its weld length requirement is not less than ten times of horizontal reinforcement diameter.
So far, finally complete horizontal structure and vertical docking of structure, and after building, form " bearing " type docking structure being commonly called as in engineering.
Complete after above-mentioned implementation process the following characteristics of the present invention of should withdrawing deposit out:
1) by embedded bar 1, coordinate horizontal reinforcement 3 that horizontal structure can firmly fast be docked with vertical structure;
2) when being convenient to formwork for placing setting, by isolation strip 3, reduce and again carry out the difficulty of concrete Weeding, even avoid this work;
3), by above implementation process, further strengthen globality and the intensity of docking structure.
Below embodiment has been described in detail the present invention by reference to the accompanying drawings, and those skilled in the art can make many variations example to the present invention according to the above description.Thereby some details in embodiment should not form limitation of the invention, the present invention will be usingd scope that appended claims defines as protection domain.
