Abstract
The utility model discloses a RC spilt hollow shear wall, which consists of a plurality of reinforcing units (1), a formwork (2) is arranged between the two reinforcing units so that a longitudinal seam is formed; a cylindrical internal formwork (3) is placed at the center of the shear wall so that longitudinal cavities are formed. The utility model has smaller rigidity compared with the common shear wall, long self-vibration period, low earthquake response, saved materials, high bearing capacity, good effects in sound/heat insulation and heat preservation, light selfweight, as well as an ideal structure system with good earthquake-resistant behavior and reasonable construction cost, therefore, is suitable for multistory and small-and-median high-rise housing, and buildings with frame shear wall, larger space at ground/high-rise floor.
Description
The utility model relates to the building structure member, particularly the split type hollow shear wall slab of steel concrete.
China is populous, but one mu of per capita area of cultivated farmland less than.Loam brick is used in construction work in a large number, and the arable area of China is reduced with surprising rapidity.Country attaches great importance to this situation at present, calls the whole nation to quicken the wall reform paces, abolishes the application of loam brick in building construction as early as possible, to protect the fields, saves the energy, the conservation of nature environment.
At present, some earthquake areas multilayers and little high-story house adopt common reinforced concrete shear wall structure.Because this body of wall rigidity is big, certainly the shake cycle short, the house is from great, so geological process is big, and its to destroy form be the shear failure of fragility, in order to resist bigger seismic shear, must the enlarging section size and increase quantity of reinforcement.The split type hollow shear wall slab of steel concrete of the present utility model, be to draw common reinforced concrete shear wall good integrity, the bearing capacity height, advantages such as anti-seismic performance is good, overcome its use with multilayer and in the small sized multiple story building from great, certainly the shake cycle short, earthquake response is big, the cost height destroys a kind of new structure plate that the shortcomings such as shear failure for fragility propose.This plate is utilize to adjust the rigidity of building self and deadweight and reach a kind of shock-damping structure plate that reduces geological process.
The purpose of this utility model is to propose a kind of bearing capacity height, sound insulation, insulation, good heat-insulation effect, good from heavy and light, anti-seismic performance, mainly is suitable for multi-storey building, little high residential building and the split type hollow shear wall slab of steel concrete of the more public building of wall in length and breadth.
Technical solution of the present utility model is achieved in that
The split type hollow shear wall slab of steel concrete is made up of a plurality of arrangements of reinforcement unit (1), separates with template (2) between each arrangement of reinforcement unit (1), forms vertically seam; Put into cylindrical internal mold (3) in the middle of the shear wall slab, in wallboard, form vertical hole (4).
Shear wall slab is all reserved connecting reinforcement (5) up and down, and the wallboard side adjacent with constructional column also reserved the reinforcing bar (6) that is connected with constructional column.
This shear wall slab both can adopt the assembled integral construction, also can adopt the cast-in-site construction.
Template (2) thickness between the wall panel element (1) is generally 8～12mm, and this template can adopt disposable template, also can adopt tool-typed formwork.
Alleged split type of the utility model is meant with shear wall with vertical seam separately, forms shear wall with seam.Alleged hollow being meant before the shear wall fluid concrete put into cylindrical internal mold, makes and forms vertical hole within the walls, just as the hole heart floor of erectting.
The utlity model has following beneficial effect:
1, body of wall of the present utility model has been protected the farmland without loam brick, saves the energy, has avoided firing the atmosphere that loam brick causes and the environment pollution on ground.
2, alleviate dead load, economical with materials.Compare with common shear wall, weight can alleviate 25%～30%, has also saved the concrete of same ratio.
3, bearing capacity height, anti-seismic performance is good.The vertical bearing capacity of this wall is 4～5 times with cross section clay brick masonry wall; Shear-carrying capacity is 3～4.5 times of clay tile wall.This means that under the condition of identical wall thickness, the height of building can improve more than the twice.This is to improving land utilization ratio, and it is in short supply helpful to alleviate urban land.Rationally adjust the rigidity of structure, reduce geological process, both guaranteed that there is good seismic resistance in the house, reduced cost of a building again.
4, in common middle or small high-rise reinforced concrete shear wall building, owing to be subjected to the restriction of wall ratio of height to thickness, materials for wall is not fully used, and adopts hollow shear wall, has both satisfied the ratio of height to thickness requirement, and material is fully used.
5, hollow shear wall structure of the present utility model can be by the size in hole and the rigidity of reservation seam adjustment building, suitably lengthening is from the shake cycle, reduce geological process, thereby the also corresponding minimizing of sectional dimension with quantity of reinforcement, and with the brittle fracture of shearing-type change into plasticity preferably the curved scissors type destroy form, improved the ductility and the energy-dissipating property of building.
6, insulation, heat insulation, the more solid reinforced concrete wall of sound insulation value is good, energy-saving effect is obvious.
7, the internal mold pore-forming made from paper web mould or more cheap industrial waste, construction is simple, and is cheap.
Owing to the utlity model has the bearing capacity height, sound insulation, insulation, good heat-insulation effect are from heavy and light, multiple advantages such as anti-seismic performance is good, not only being fit to multilayer, medium and small high residential building, and being suitable for the more public building of wall in length and breadth, is the moderate ideal structure system of a kind of cost.This utility model is used in frame-shear wall and the bottom large space is many, in the high-story house, also can obtain same effect, thereby have wide application value.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is a wallboard sectional structure schematic diagram of the present utility model;
Fig. 2 is the structural representation of the utility model wallboard 1;
Fig. 3 is the structural representation of the utility model wallboard 2.
Embodiment 1:
Referring to Fig. 1, the form of reinforcement of the shear wall of this utility model is different with common shear wall, and it is made up of a plurality of arrangements of reinforcement unit 1, leaves the vertical slit of about 10mm between each arrangement of reinforcement unit 1, and the width of each arrangement of reinforcement unit and thickness are determined by design.Put into cylindrical internal mold 3 in the middle of the shear wall slab of each arrangement of reinforcement unit, in wallboard, form vertical hole 4.
