Abstract
The utility model relates to a revolving jointing piece used in architecture formwork system, which consists of a fastening screw rod, a joint bolt nut, a formwork and a joint screw rod. The utility model is characterized in that one end of the fastening screw rod provided with external threads is square; the joint bolt nut is fixed and connected with the fastening screw rod which goes through the other end of the formwork and is connected with the joint screw rod by the joint bolt nut; the joint bolt nut is provided with a rubber cover. One end of the joint bolt nut also can be made into a round shape, and the other end of the joint bolt nut also can be a hexagon; the joint bolt nut goes through the formwork and is sleeved with the fastening screw rod. Using a sleeve wrench to twist the fastening screw rod or the joint bolt nut to draw patterns is simple, quick, convenient, labor saving and working-hour saving. The utility model can save materials and reduce project cost; because the utility model is assembled and connected by the bolt nut and the screw rod, the exposed screw bolts at two sides of the concrete formwork and the joint bolt nut in the concrete can be used repeatedly, which saves 2/3 steel materials; the labor cost is reduced by improving the working efficiency, and the cost of raw materials like oxygen and acetylene can be omitted. As a result, the cost of a single project is greatly reduced.
Description
Technical field
The utility model relates to a kind of connector of building field, specifically relates to a kind of turnover connector that formwork system is used of building.
Background technology
The basement engineering and the civil air defense constructions and installations of present construction, function of use require reinforced concrete structure must airtightly can not seep water, breathe freely.Therefore the water proof type bolt that the connection between shear wall, post, the template is adopted in the formwork system can not be reused, and is disposable amortization part, cost height, stripping program complexity.At first want artificial form removal, and then manually cut wood glue cushion block in the concrete, the screw rod that last gas cutting excision is exposed.Because this screw rod generally exposes the outer 250mm left and right sides of concrete length, big during form removal, expose length because of screw rod density, artificial form removal effort, and also also big to the template damage.And be used for ± connecting the type bolt through walls that adopts between the reinforced concrete wall more than 0.00, post, beam forms contact the position with concrete, the way that pvc pipe is overlapped in normal employing is reused bolt.Such bolt function is single, can only play to connect the fastening effect of template, to the location of template, guarantees that the concrete structure physical dimension is correct, need set up interior support of reinforcing bar of disposable amortization in addition.This method support fixation difficulty, when loosening, template is subjected to external force vibration and often loses, and therefore the concrete component size is difficult to guarantee.And stay on concrete component and much wear the pvc pipe hole, structural element useful cross section size reduces, and is influential to the engineering structures safe mass.
Summary of the invention
The purpose of this utility model is in order to solve the shortcoming of said structure, has proposed a kind of simple in structurely, and the time saving and energy saving building formwork system that just can reach the molding effect by rotating screw bolt is with the turnover connector.
The utility model is to realize above purpose like this:
By fastening screw, attaching nut, template, the turnover connector that connecting screw rod is formed, its main points are: an end of the fastening screw of the outer silk of described band is a square, the attaching nut is fixed on the fastening screw, and the other end that fastening screw passes template is connected with connecting screw rod by the attaching nut; Described attaching nut is provided with garment bag.
For realizing that further above-mentioned purpose, described attaching nut also can be made into an end for circular, the other end is a hexagon, passes template and fastening screw socket.
The utility model advantage compared with prior art is:
1, by fastening screw, clamp nut, attaching nut, connecting screw rod and formwork system acting in conjunction, makes the template stationary positioned, guarantee project organization size constancy shape.
2, expose the hexagon of an end by rotating the outer attaching nut square or combining form of fastening screw, template is produced outward thrust, template is broken away from concrete bonding, reach the molding effect.
3, adopt box spanner to rotate fastening screw or attaching nut's molding, simple, quick and easy, laborsaving, save man-hour.
4, save material, reduction construction costs: because this utility model is to be connected with screw combinations by nut, the attaching nut is reusable in the exerted bolt on concrete blinding both sides and the concrete, saves steel 2/3; Reduce labour cost by improving work efficiency, save oxygen, acetylene raw material expense etc.Greatly reduce the individual works cost.
5, can select whole form turnover connector or combining form turnover connector for use according to different demand conditions.
