Description
Technical field
The utility model relates to a kind of cast support frock, and especially a kind of shape of a saddle hyperboloid concrete slab cast support frock belongs to technical field of building construction.
Background technology
By space geometry as can be known, hyperbola is rotated around ellipse can form hyperboloid, for example, locates elliptic equation zero point at the z axle and is:
Locating Hyperbolic Equation zero point at the y axle is:
When being rotated along ellipse, above-mentioned hyperbola can form hyperboloid.And under hyperboloid with the quadrangle projection that makes progress, cut a curved surface that at hyperboloid and be shape of a saddle hyperboloid.
Along with becoming increasingly abundant of architectural image is colorful, shape of a saddle hyperboloid structural construction exterior design is applied.This structure has broken through construction pattern in the past, has the individual style at a pair of upper uplifting angle and a pair of sinking angle.Yet, because shape of a saddle hyperboloid complex shape adopts traditional falsework to realize that the concrete slab structure needs to make the curve skeleton, not only very high to operating personnel's technical requirements, be difficult to guarantee construction quality, and work efficiency is extremely low, can't satisfies modern building operations schedule requirement.
The utility model content
The purpose of this utility model is: a kind of assurance under the required curve form prerequisite proposed, and the simple shape of a saddle hyperboloid concrete slab cast support frock of constructing, thus lay the foundation for follow-up concreting.
In order to reach above purpose, shape of a saddle hyperboloid concrete slab cast support frock basic structure of the present utility model is: the three-dimensional support system that comprises sweep the floor bar and vertical vertical rod and the supplemental support formation of flat grid structure, described vertical vertical rod is set up on the intersection point of plane grid, and the height of each vertical vertical rod is determined by the bi-curved corresponding projector distance of the shape of a saddle yet to be built respectively; The top of described vertical vertical rod respectively with stupefied being connected of straight line master spaced apart, constitute hyperboloid support beam spaced apart; It is time stupefied to bear fixing straight line of arranging according to the order of sequence with predetermined density on described straight line master is stupefied, constitutes hyperboloid space grid; Described straight line time stupefied going up covers fixed panel, forms the hyperboloid template.
On this basis, can carry out assembling reinforcement smoothly, form hyperboloid and build operations such as cavity and concreting, obtain the shape of a saddle hyperboloid concrete slab of good looking appearance.
Described panel of the present utility model can be spliced by the gummed lath, thereby the profiling effect is better.Amount of deflection by adjustable holder support and stupefied being connected of straight line master spaced apart, therefore can be eliminated by regulating respectively in the top of described vertical vertical rod, makes vertical vertical rod and main stupefied more accurate the stablizing that be connected.
The utility model is ingenious to utilize hyperboloid to have that any point all can be extended out the geometrical property that is positioned at two intersecting straight lines on the hyperboloid on it, only needing conventional straight line building materials just can form end face is the bi-curved support frock of the shape of a saddle, need not to draw complicated curve, also needn't make bent member fully, it is very easy to construct, technical ability to the operator is less demanding, is easy to guarantee that concrete structure moulding impression is good.

The specific embodiment
Embodiment one
The shape of a saddle hyperboloid concrete slab cast support frock of present embodiment is made by following concrete steps:
The first step, measure unwrapping wire---any point all can be extended out the geometrical property that is positioned at two intersecting straight lines on the hyperboloid on it because hyperboloid has, therefore can form the 3-D geometric model of waiting to make up shape of a saddle hyperboloid concrete slab by computer graphics instruments such as solidworks, and set up the space lattice that intersects the space line formation by predetermined accuracy thereon, be projected as the plane grid that the intersecting plane straight line constitutes with this space lattice is vertical again, the space intersection point in the space lattice is corresponding one by one with projection intersection point in the plane grid.
Second step, set up stand---go out and wait to make up the corresponding actual ratio plane grid of shape of a saddle hyperboloid space lattice in construction ground setting-out, and sweep the floor bar 2 and the vertical vertical rod 1 of taking the corresponding grid of formation by the true planar grid, vertical vertical rod 1 is set up on above-mentioned actual ratio plane grid intersection point, and the height of each vertical vertical rod is pressed 3-D geometric model space intersection point to the actual range of corresponding projection intersection point respectively and set (referring to Fig. 1).
The 3rd step, make up support system---by overlap joint cross bar 3, oblique supplemental support such as bridging (not shown), constitute to be mutually related with vertical rod 1 and stablize three-dimensional support system (referring to Fig. 2).
Stupefied of the 4th step, installation---will be connected with corresponding each vertical vertical rod 1 top according to the order of sequence with the corresponding position of 3-D geometric model space networks ruling respectively as main stupefied 4 steel pipe straight line building materials, constitute the parallel hyperboloid support beam spaced apart of projection.To bear according to the order of sequence with predetermined density as 50mm * 50mm flitch straight line building materials of inferior stupefied 5 again and be fixed on main stupefied 4 formation hyperboloid space grid (referring to Fig. 3).
The 5th goes on foot, builds template---to lay the gummed lath Mosaic face plate 6 of fixing wide 50～200mm thereon with inferior stupefied oblique crossing direction, until forming hyperboloid template (referring to Fig. 4) at hyperboloid space grid.
So just, can be made into the shape of a saddle hyperboloid concrete slab cast support frock of structure shown in Figure 4: the three-dimensional support system that comprises sweep the floor bar 2 and vertical vertical rod 1 and supplemental support cross bar 3 formations of flat grid structure.Vertical vertical rod 1 is set up on the intersection point of plane grid, and the height of each vertical vertical rod 1 is determined by the bi-curved corresponding projector distance of the shape of a saddle yet to be built respectively.Support with the stupefied 4(of straight line master spaced apart referring to Fig. 2 by adjustable holder respectively at the top of vertical vertical rod 1) be connected, constitute hyperboloid support beam spaced apart.Bear the fixing straight line time stupefied 5(that arranges according to the order of sequence with predetermined density on the straight line master stupefied 4 referring to Fig. 3), constitute hyperboloid space grid.Cover the panel 6 that fixing glue plywood bar is spliced on the straight line inferior stupefied 5, form the hyperboloid template.
Afterwards, finish at hyperboloid template edge fixed form rib, assembling reinforcement, construction cover plate, both can carry out concreting, obtain required shape of a saddle hyperboloid concrete slab.
Facts have proved that the cast support frock making of present embodiment is easy, profiling is effective, only needs conventional building materials, and is not high to operator's technical requirements, helps to improve work efficiency, satisfies modern building operations schedule requirement.
