Background technique
In the work progress such as Tall Shear Wall Structures, due to controlling improper or other reasons, concrete strength is caused not
Foot, the i.e. bearing capacity of structure can not meet design requirement, then needing to carry out reinforcement and strengthening to the structure to go wrong, make it
Meet the needs of safe handling, common reinforcement means has Enlargement of Section, the concrete of aliquot replacement shear wall, all displacement
The concrete etc. of shear wall；In engineering, the lower floor shear wall concrete quality of such as construction differs greatly with design requirement,
In the case that increasing section and aliquot replacement concrete are unable to satisfy, then walls concrete is all replaced, such as the building
It has all bound or has approached and bound, then during replacing concrete wall, after removing one section of wall, it is likely that due to structure
The missing of part causes structure itself to be collapsed, and causes engineering accident.
Utility model content
For the defects in the prior art, the utility model provides a kind of shear wall that segmented is reinforced, by constantly counting
It calculates, construction carrying when whether the concrete area after determining the concrete area that can be replaced every time and displacement meets displacement next time
The requirement of power can repeatedly replace concrete, finally by low quality and heavily stressed concrete wall is replaced, solve and apply
The problem of work is safe and support can not be arranged.
The shear wall that a kind of segmented of the utility model is reinforced is equipped with displacement steel in the part of original structure concrete chisel removal
Muscle and vertical slot steel, and it is cast with displacement concrete, displacement reinforcing bar includes main reinforcement and stirrup, and main reinforcement retains with original structure concrete
Together, main reinforcement is banded together reinforcement welding by stirrup, and by original structure concrete interface dabbing before casting, male and fomale(M&F) is deep
Degree: beam is no less than 6mm, and plate is no less than 4mm, removes completely broken concrete, dross ash with steel brush after dabbing, original structure is mixed
Solidifying soil surface washing is clean, then with fresh No. 425 cement slurries or interfacial agents paint surfaces, is welded and fixed between stirrup and main reinforcement,
Ensure stabilized structure, it is closely knit to replace concrete vibrating after casting, cuts redundance after displacement concrete initial set is closely knit.
Further, it is built up by the way of segmented casting, primary segmentation first is carried out to original structure concrete and is cut, then
Once-cast is carried out cutting position, after the displacement concrete hardening that once-cast is formed, in remaining original structure concrete
Wall section carries out secondary segmenting and cuts, and then carries out second pouring in the secondary position that cuts, until full wafer wall section is replaced, one section
Wall can be divided into secondary, even four displacements completion three times, solve the problems, such as the displacement of full wafer wall section and support can not be arranged.
Further, the displacement concrete shrinks concrete, grade C35, the swelled mixture of the UEA of interior incorporation 12% using compensation
Solidifying soil, expansion rate are (2 ~ 3) × 10-4, anti-crack ability greatly improved.
Further, main ribs are multiple and left and right arrangement is two rows of, the vertical slot steel be placed in the two rows of main reinforcements in left and right it
Between, vertical slot steel be it is multiple, uniformly arranges between the two rows of main reinforcements in left and right, displacement concrete structural strength can not only be improved, and
Preferable supporting role can be played.
Further, the vertical slot steel is held out against with original structure concrete upper and lower interface, can effectively be propped up superstructure
Support, it is ensured that construction safety.
Further, the vertical slot steel uses No. 12.6 channel steels, and at low cost, comprehensive performance meets building requirements.
Further, thickness of the thickness of the displacement concrete not less than the part of original structure concrete chisel removal；It is allowed to full
The requirement of sufficient structural strength, rigidity and bearing capacity.
The beneficial effects of the utility model are: the shear wall that a kind of segmented of the utility model is reinforced, by constantly counting
It calculates, construction carrying when whether the concrete area after determining the concrete area that can be replaced every time and displacement meets displacement next time
The requirement of power can repeatedly replace concrete, finally by low quality and heavily stressed concrete wall is replaced, solve and apply
The problem of work is safe and support can not be arranged.
Detailed description of the invention
It, below will be right in order to illustrate more clearly of specific embodiment of the present invention or technical solution in the prior art
Specific embodiment or attached drawing needed to be used in the description of the prior art are briefly described.In the accompanying drawings, similar element
Or part is generally identified by similar appended drawing reference.In attached drawing, each element or part might not be drawn according to actual ratio.
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the plan view for needing reinforcing wall.
Specific embodiment
It is described in detail below in conjunction with embodiment of the attached drawing to technical solutions of the utility model.Following embodiment is only
For clearly illustrating the technical solution of the utility model, therefore it is only used as example, and it is originally practical to cannot be used as a limitation limitation
Novel protection scope.
It should be noted that unless otherwise indicated, technical term or scientific term used in this application should be this reality
The ordinary meaning understood with novel one of ordinary skill in the art.
It is as shown in Figure 1, 2: the shear wall that a kind of segmented of the present embodiment is reinforced, in the portion that original structure concrete 1 is cut
It is arranged with displacement reinforcing bar and vertical slot steel 5, and is cast with displacement concrete 2, the displacement concrete 2 shrinks concrete using compensation, etc.
Grade is C35, and the expansive concrete of the UEA of interior incorporation 12%, expansion rate is (2 ~ 3) × 10-4, anti-crack ability greatly improved；It is described
Thickness of the thickness of displacement concrete 2 not less than the part that original structure concrete 1 is cut；Be allowed to meet structural strength, rigidity and
The requirement of bearing capacity；Displacement reinforcing bar includes main reinforcement 4 and stirrup 3, and the reinforcement welding that main reinforcement 4 and original structure concrete 1 retain is one
It rises, main reinforcement 4 is banded together by stirrup 3, and by 1 interface dabbing of original structure concrete before casting, male and fomale(M&F) depth: beam is no less than
6mm, plate are no less than 4mm, remove completely broken concrete, dross ash with steel brush after dabbing, 1 surface of original structure concrete is rushed
Wash clean, then with fresh No. 425 cement slurries or interfacial agents paint surfaces, be welded and fixed between stirrup 3 and main reinforcement 4, it is ensured that structure
It is firm, 2 vibration compacting of concrete will be replaced after casting, redundance be cut after 2 initial set of displacement concrete is closely knit, using segmentation
The mode of formula casting is built up, and first be once segmented to original structure concrete 1 and is cut, and is then once poured cutting position
Note carries out secondary segmenting chisel in remaining 1 wall section of original structure concrete after the displacement concrete 2 that once-cast is formed hardens
Remove, then carry out second pouring in the secondary position that cuts, until full wafer wall section is replaced, one section of wall can be divided into it is secondary,
Even four displacements are completed three times, as shown in Fig. 2, displacement is completed in four times, label a is first time replacing section, and b is second
