Abstract
The utility model discloses a shear wall of a high-rise building, which relates to a building member. The shear wall is characterized in that: double-rib grid welded meshes are built on the top of each building block in the edge member range of the end part of the shear wall; spiral hoops matched with the meshes are arranged in the holes of the building blocks, and are bound and fixed with mesh steel bars through fine reinforcing wires; a horizontal steel bar and a vertical steel bar of each building body are arranged as specified in the conventional way; and special grout concrete is poured on the horizontal steel bars and the vertical steel bars to form a shear wall structure with a restraining edge member. Due to the adoption of the shear wall, the problems of low shock deformation resistance (such as ductility) and low bending resistance of an RM shear wall caused by low restraining action since structures such as restraining steel bars, restraining plates and the like are arranged in building body mortar joints in the conventional national and international RM shear wall edge members are solved. The shear wall plays an important role in facilitating the popularization and application of a high-rise RM shear wall room and enhancing the shock resistance reliability of the structure.

The specific embodiment
With reference to the accompanying drawings the utility model is elaborated.
Combined type constraint structure of the present utility model is made up of main two parts, and its effect and function are described below respectively:
Two muscle lattice welded mesh sheets, can adopt fine steel rib (as
) the stitch welding moulding.The two vertical muscle of net sheet have strengthened the bond area with the mortar joint mortar, and net sheet horizontal bar is embedded in the grout concrete simultaneously.Like this net sheet in length and breadth reinforcing bar the masonry (comprising reinforcing bar) of confining region is formed two-way effect of contraction, improve a lot than the effect of contraction of single reinforcement welded mesh sheet or stirrup.According to the size (long 600 ㎜, wide 900 ㎜) of RM shear wall edge member regulation, the conversion volume distributed ratio of two muscle lattice net sheets
=0.0026, convert and join the hoop characteristic value
The closed spiral stirrup of upper and lower side, the perpendicular masonry hole inboard of pasting, the concrete column with grout concrete formation space constraint promptly really reaches the strong constraint effect of constrained edge member in the RC shear wall.By the minimum technical data of present technique, get the spiral stirrup diameter
, pitch is 40 ㎜, its volume distributed ratio
, convert and join the hoop characteristic value
So only the hoop characteristic value of joining of spiral stirrup has just exceeded concrete specification constrained edge member
Requirement.
And combined type constraint structure is an integral body, so it act as the two stack, i.e. and its volume distributed ratio
, join the hoop characteristic value accordingly
, much larger than
, the enhancing of its effect of contraction is described.Compare with the edge member that single reinforcement net sheet, stirrup only are set in horizontal mortar joint, only press the effect of contraction of the spiral stirrup of present technique, the bending resistance of masonry is improved more than 50%, thereby the deformability of wall sheet and anti-seismic performance have a greater degree of improvement and are high.
Colligation is with finer wire 3, be used for closed spiral stirrup 2 fixing on two muscle lattice welded mesh sheets 1, and place in the building block 4, vertical reinforcement 5 strengthen with, be located in the spiral stirrup 2.
The utility model is applicable to the edge member technical measures of high-rise RM shear wall in the reinforcement of the structure reinforcement district or the region of high stress---combined type constraint structure.It comprises two muscle lattice welded mesh sheets and the closed spiral stirrup of upper and lower side, in the edge member zone of masonry with mortar joint mortar and grout concrete, masonry form strong constraint edge member.Be applicable to that (the wall section end as ratio of axial compressive force to axial compressive ultimate capacity of section σ/fg) 〉=0.4 is provided with this combined type constraint structure, i.e. the constrained edge member for the reinforcement district of high-rise RM shear wall structure in the area of providing fortification against earthquakes or the region of high stress.The constrained edge member of strengthening by the utility model structure can meet or exceed effect of contraction and the function that RC shear wall constrained edge member should reach fully.Therefore the utility model measure can be directly used in the body of wall position that the RM shear wall need be provided with the constrained edge member.The constrained edge member that adopts this combined type constraint structure to form, realized three-dimensional effect of contraction to reinforced region, this is to constraint reinforcing steel bar bear performance---the great change of the masonry stress of unilateral constrain is set in mortar joint separately, i.e. great change from the plane to the space constraint, also be the variations of this technical measures in the matter of the stressed generation of masonry of confining region, the value place of this measure just.Because the building block hole is in 120 ㎜ * 120 ㎜ scopes, after adding the closed spiral stirrup up and down that internal diameter is 100 ㎜, reduced the concrete space of cast grout, therefore to adopt special-purpose grout concrete also should meet the regulation of " concrete block (brick) is used the grout concrete " JC861-2008, and employing minor diameter concrete vibrating rod, i.e. diameter≤25 ㎜.The domestic existing production of this minor diameter vibrating spear and using in the RM shear wall engineering at home.Adopting special-purpose grout concrete (in the masonry structure standard as compulsive clause) and minor diameter vibrating spear is the key of guaranteeing RM edge member concrete compaction.
