Description
Technical field
The utility model relates to the concrete prefabricated element field, relates in particular to a kind of clear-water concrete precast stand slab.
Background technology
Clear-water concrete (As-cast Finish Concrete/BareConcrete) claim ornamental concrete again; Because of having decorative effect, it gains the name.It belongs to one-time cast-forming; do not do any outer decoration; directly adopt the natural surface effect of cast-in-situ concrete as facing; therefore be different from ordinary concrete; surfacing is smooth, color and luster is even, corner angle are clearly demarcated, no clashing and breaking and pollution; just be coated with one deck or two-layer transparent protective agent, seem very natural on the surface, serious.
Clear-water concrete is the five-star expression-form of concrete material, and what its showed is the most essential a kind of aesthetic feeling, embodiment be the taste of " wearing no make-up during an audience with the emperor ".Clear-water concrete has simple and unadorned, sedate naturally outward appearance charm, inherent thick and heavy and elegant be that some modern architecture materials can't be imitateed and match in excellence or beauty.The soft feeling that material itself is had, firm sense, warming sense, cold and detached sense not only exert an influence to people's sense organ and spirit, and can give expression to the building emotion.Therefore architects think that this is a kind of simplicity of noble quality, seem simple, the splendid artistic effect that has more of its fullsized.
The bleacher of present large-scale gymnasium mostly is the concrete cast-in-site and forms, and is characterized in that area is big, reaches 4.5 ten thousand square metres as sports palace, Olympics, Shenyang City area, can hold 60,000 people, is the stadiums of the Northeast and even domestic maximum.Cast-in-site see platen, the coarse surface decoration effect that does not reach clear-water concrete of concrete surface, construction period is generally longer in addition, can not satisfy the requirement of duration.
Summary of the invention
The purpose of this utility model provides a kind of clear-water concrete precast stand slab, and surface decoration effect is good, physical dimension precision height, short construction period.
For achieving the above object, the utility model is achieved through the following technical solutions:
The clear-water concrete precast stand slab is characterized in that, these prefabricated units are " L " shape structure, long 6～12m, and the minor face end is provided with stage, and end, long limit is provided with boss, and stage matches with the boss geomery.
Described prefabricated units are "T"-shaped structure, long 6～12m, and a side minor face end is provided with stage, and end, corresponding long limit opposite side is provided with boss, and stage matches with the boss geomery.
Cooperation position is provided with built-in fitting on long limit of described prefabricated units and the minor face, grows the limit boss, when the minor face stage is overlapped to form sandwich construction successively, is connected by built-in fitting at a plurality of prefabricated units.
Compared with prior art, the beneficial effects of the utility model are: good, the smooth surface good decorating effect of the compactness of member own, simple for production, turn around time weak point, physical dimension exquisiteness, closely knit gloss, speed of application are fast, batch process, superposed type assembling, adopt prefabrication to replace cast-in-place manufacture craft and measure, reduce engineering cost, be specially adapted to assembling in the large-scale stadium, the demanding reinforced concrete structure of decorative effect.
Description of drawings
Fig. 1 is the utility model structure one schematic diagram;
Fig. 2 is the utility model structure two schematic diagrames;
Fig. 3 is that the utility model is used schematic diagram.
Among the figure: the 10-built-in fitting of the long limit of the long limit 5-built-in fitting 6-stage 7-boss 8-minor face 9-of 1-stage 2-boss 3-minor face 4-.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further:
See Fig. 1, clear-water concrete precast stand slab, these prefabricated units are " L " shape structure, long 6～12m, and minor face 3 ends are provided with stage 1, and 4 ends, long limit are provided with boss 2, and stage 1 matches with boss 2 geomeries.
See Fig. 2, described prefabricated units are "T"-shaped structure, long 6～12m, and a side minor face 8 ends are provided with stage 6, and corresponding long limit 9 end opposite sides are provided with boss 7, and stage 6 matches with boss 7 geomeries.
See Fig. 3, cooperation position is provided with built-in fitting 5, built-in fitting 10 on long limit of described prefabricated units and the minor face, grows the limit boss, when the minor face stage is overlapped to form sandwich construction successively, is connected by built-in fitting 5, built-in fitting 10 at a plurality of prefabricated units.
The utility model is compared with conventional member, its structure satisfies and meets design drawing and current national codes requirement, because its presentation quality far surmounts existing GB requirement, technology quality height, this technology extends to other concrete workes, the effect of stone is accomplished seemingly to manage in the surface, has powerful social benefit and economic benefit, is irreplaceable high new product and has the powerful market competitiveness.
The utility model main points of operation is:
