Embodiment one:
As shown in Figure 1, a kind of concrete circular arc type formwork structure, including exterior sheathing 1, floor 2, circular arc-shaped corner 3 and face
To the inner template of concrete, it is fixedly connected between the exterior sheathing 1 and the exterior sheathing by floor 2, the inner template includes
First side plate 41 and the second side plate 42 are connected between first side plate 41 and second side plate 42 by circular arc-shaped corner 3.By
This structure places formwork structure it is found that when large box girder concrete cast-in-situ is constructed before cast-in-place concrete, exterior sheathing towards
Concrete, inner template are used to support exterior sheathing, are connected between exterior sheathing and inner template by floor 2, wherein exterior sheathing includes the
Side plate 41 and the second side plate 42 are connected between first side plate 41 and the second side plate 42 by circular arc-shaped corner 3.Circular arc-shaped corner 3 can
It is concentrated with effectively mitigating the stress of corner, avoids the problem that template is not connected firmly and leads to damaged template, on the other hand, tearing open
It can avoid causing damage when demoulding to corner and the phenomenon that arrisdefect, dew muscle occur, while circular arc-shaped corner 3 with overall pulling down when mould
With can also ensureing after box beam carrying stress transfer along the general character.
Preferably scheme, the number of floor 2 be it is multiple, the floor 2 is distributed in the two sides of circular arc-shaped corner 3.Thus structure
It is found that as shown in the figures 1 and 2, multiple floors 2 connect exterior sheathing and inner template, play the role of reinforcing rib.
Preferably scheme, floor 2 are I-steel or channel steel.Thus structure is it is found that I-steel or channel steel have stronger resist
Curved ability, the stress being highly resistant in concreting process, in addition, the edge of a wing scale face of fashioned iron is parallel to each other, so that its
It is easy in the connection with exterior sheathing and inner template, processing and installation.
Preferably scheme, circular arc-shaped corner 3 and the exterior sheathing are an overall structure.Thus structure is it is found that overall structure
Can effectively prevent the spillage problem of cast-in-place concrete, can also prevent because connector it is insecure caused by damaged template or production
Raw crack problem.
Preferably scheme, the both ends of circular arc-shaped corner 3 are welded with first side plate 41 and second side plate 42 respectively.By
This structure is it is found that by cast-in-place the first side plate of site welding, the 41, second side plate 42 and circular arc-shaped corner 3, so that exterior sheathing is one
A overall structure, mortar leakage prevention.
The radius of preferably scheme, circular arc-shaped corner 3 is greater than or equal to 5cm.Thus structure it is found that too small arc radius not
Can effectively excessive concrete cast-in-situ when stress.
Preferably scheme, circular arc-shaped corner 3 are inner concave shape circular arc-shaped corner or male type circular arc-shaped corner.Thus structure is it is found that such as
Shown in Fig. 1 and Fig. 2, when large-sized concrete structure corner indent, concrete can be thickened using inner concave shape circular arc-shaped corner form
Protective layer thickness；When large-sized concrete structure corner evagination, using male type circular arc-shaped corner form, guarantee the thickness of protective layer
Meet environmental requirement and standard regulation, further, it is also possible to be equipped with arrangement of reinforcement in male type circular arc-shaped corner, does not reduce main reinforcement length
In the case of degree, arrangement of reinforcement is equipped with circular arc crotch corresponding with male type circular arc-shaped corner, while not influencing protective layer thickness, moreover it is possible to
Guidance cast-in-place concrete internal stress is sustained along corner, and stress is avoided excessively to concentrate.
Preferably scheme, inner template corner are arc surface, and the arc surface and the inner template are an entirety.Thus it ties
For structure it is found that inner template also is provided with arc surface corresponding with exterior sheathing, exterior sheathing passes the power generated during concrete cast-in-situ
Inner template is passed, it is slowly excessive by arc surface when the stress of inner template two sides converges on the corner, effectively reduce right-angled bend
Corner splits caused by Shi Yingli is concentrated.
Embodiment two: a kind of concrete circular arc type formwork structure, including inner template, floor 2, exterior sheathing and circular arc-shaped corner
4, it is fixedly connected between the inner template and exterior sheathing by floor 2, the exterior sheathing is equipped with circular arc-shaped corner 4, wherein circular arc turns
Angle 4 is male type circular arc.
As shown in Fig. 2, the concrete of the present embodiment is the same as example 1 substantially with circular arc type formwork structure, difference exists
In arc chord angle 3 be male type circular arc-shaped corner.It just no longer repeats one by one herein.
Specific construction step are as follows: the setting of large-sized concrete structural body corner is in the arc-shaped, it can be and be forged into one in advance
A overall structure, or scene weld the first side plate, circular arc-shaped corner and the second side plate.When working out template construction plan,
Steel form corner is designed to one piece two to isometric sizing monolith steel form in advance, punching block board ends connect rib and punching block hangs down
Directly, it can be docked when being connect with adjacent punching block tight.Arc radius should generally be not less than 5cm, while according to structural body arrangement of reinforcement feelings
Condition guarantees that the protective layer thickness of crotch is designed when not reducing main reinforcement straight length.Round lead angle is arranged according to structure
Body corner situation considers that, when structural body corner indent, corner arrangement of reinforcement does not change in two kinds of situation；When structural body corner evagination
When, corner reinforcing bar crotch is also provided in the arc-shaped, while guaranteeing protective layer thickness not less than standard requirements
Exemplified as above is only to the utility model for example, not constituting to the protection scope of the utility model
Limitation, within all designs the same or similar with the utility model all belong to the scope of protection of the present invention.
