Technical field
The utility model belongs to the technical field of construction equipment device, and in particular to a kind of adjustable spiral shell of one side formwork
Bolt fastener.
Background technology
Building template is a kind of temporary supporting structure, is made by design requirement, makes concrete structure, component by defined
Position, geometric dimension forming, keep its correct position, and bear the external loads of building template dead weight and effect on it.Into
The purpose of row form work engineering is to ensure concrete engineering quality and construction safety, accelerate construction progress and reduce engineering cost.
The working architectural template structure of Cast-in-situ Concrete Structural Engineering, mainly by panel, support construction and connector three
Part forms.Panel is the force bearing plate for being in direct contact newly-laid concrete；Support construction is then supporting faceplate, concrete and construction lotus
The temporary structure of load, ensure architectural template structure combine securely, accomplish it is indeformable, do not destroy；Connector is by panel and branch
Support structure connects integral accessory.
Building template is the formwork and holder of concreting forming, can be divided into building template, building by the property of material
Wood glue plate, film coated plate, multi-layer board, two-sided re-glue, two-sided laminated construction formwork etc..Building template can be divided by construction technology condition
Cast in place concrete form, large form, rises to template etc. at pre-assembled template.
In Building Construction, since shear wall outside suitable for reading and toilet beam inner side majority are to face vacancy
It sets, when carrying out template installation here, cannot be reinforced to drawing, formwork bracing system is brought without supporting and drawing point to formwork reinforcement
Very big difficulty, causes shear wall, the toilet formwork reinforcement suitable for reading not in place, gets a foothold without branch when installing a story shear wall form
Support and reinforcement point, very big hidden danger of quality is caused to concrete formation quality.The installation of the template of the position was usually taken in the past
Nail is nailed in already installed Bars In Poured Concrete Slab template is wound in length and pine on nail by adjusting iron wire with iron wire again
Tight to be corrected and reinforce to template, template deforms due to iron wire poor rigidity, simultaneously because iron wire pulling force is not
Loosely concrete vibrating is easy to be pulled off and quick-fried mould occurs in the process for foot, fixed point.
Utility model content
When carrying out template installation to shear wall outside suitable for reading and toilet beam inner side for the prior art it is existing not
Foot place, the utility model proposes a kind of one side formwork adjustable bolt fastener, building template adjustable bolt fastenings
The problem of part was difficult to reinforce when both having overcome formwork bracing system without supporting point, template goes out during also avoiding casting concrete
Quick-fried mould now occurs during deformation and concrete vibrating.
The utility model adopts the following technical solution：
A kind of one side formwork adjustable bolt fastener, it includes bolt head, the first screw rod, the second screw rod, third screw rod
And bolt, it is connected by electric welding between bolt head, the first screw rod, the second screw rod and third screw rod, the first screw rod, the second spiral shell
The end of bar and third screw rod is equipped with screw thread, is connected by screw thread between bolt and the first screw rod, the second screw rod, third screw rod
It connects, the outer profile of bolt head is regular hexagon, and bolt head is equipped with eyelet.
Further, the longitudinal section of bolt is trapezoidal, and its longer so-called fixed bottom surface in bottom edge is opposite with bolt head.
Further, the length of the first screw rod is less than the length of the second screw rod, and the length of the second screw rod is less than third screw rod
Length.
Further, the first screw rod, the second screw rod are identical with the length of third screw rod.
Further, the first screw rod, the second screw rod are identical with the reach of third screw rod end.
Further, eyelet there are six being set on bolt head.
The utility model has the following advantages that relative to traditional architecture template fastener：1, formwork bracing system is overcome
The problem of being difficult to reinforce when no supporting point；2, template during casting concrete is avoided to occur deforming and concrete vibrating process
It is middle that quick-fried mould occurs；3, the utility model can realize the adjusting to spiro rod length by the position of bolt, therefore applicability is stronger.
