Abstract
Utility model provides a kind of new cooling sealing up screw.The cooling sealing up screw includes two external screw rods, and the casing being connected between external screw rod.The both ends of described sleeve pipe are both provided with and the matched internal thread screw thread of external screw rod external spiral screw thread.The periphery of described sleeve pipe is arranged with cooling tube.The middle part of the cooling tube is equipped with hydro-expansive rubber seal ring.Elastic rubber round platform is also socketed with the external screw rod.When pouring into a mould concrete, the free end of the external screw rod is positioned in template by nut.Template is close in the side bottom surface of the elastic rubber round platform, and opposite side bottom surface contact is at the mouth of pipe of cooling tube.The cooling sealing up screw can cool down wall by cooling tube, reach the effect of control critical eigenvalue.External screw rod assembling and disassembling is simple and convenient, and engineering construction is efficient.
Description
Technical field
Architectural engineering concrete works and form work engineering field are the utility model is related to, it is more particularly to a kind of to reduce concrete
Temperature and then control distress in concrete, while play a kind of new cooling sealing up screw of sealing effect.
Background technology
The domestic usual cast in situs of building shear wall, when building formwork for placing, it is necessary to which substantial amounts of split bolt comes
Fixed, drawknot template, the wall high to waterproof requirement, it is also necessary to consider the water-proofing treatment of Screw arbor with nut at both-ends, the most common are use
Sealing up screw.In addition, pour and often due to hydrated cementitious, concrete internal temperature is high, and internal-external temperature difference is big in maintenance processes, production
Raw temperature stress, and then thermal cracking is produced, it is necessary to take certain cooling measure, such as pre-buried water pipe.
Traditional sealing up screw waste of materials and construction cost height.After the completion of shear wall pours, usually have very in template
More sealing up screw pass through, and cause form removable to be not easy, and dismounting speed is slow, or even can damage template.This kind of screw rod cannot be from wall
Taken off on body, it is necessary to exposed part is sliced off, and cannot be reused.Meanwhile be retained in concrete wall mileage amount compared with
More, get rusty easily expansion, influences concrete durability.
Utility model content
The purpose of this utility model is to provide a kind of new cooling sealing up screw, to solve existing in the prior art ask
Topic.
To realize that the technical solution that the utility model aim uses is a kind of such, new cooling sealing up screw, bag
Include two external screw rods, two elastic rubber round platforms, and the casing being connected between two external screw rods.
The both ends of described sleeve pipe are both provided with and the matched internal thread screw thread of external screw rod external spiral screw thread.Described sleeve pipe
Periphery be arranged with cooling tube.The middle part of the cooling tube is equipped with hydro-expansive rubber seal ring.
Axial hole is provided with the elastic rubber round platform.Described two elastic rubber round platforms are tightly sleeved in cooling respectively
The both ends of pipe.
During work, template inner surface is close in the side of the elastic rubber round platform away from casing.The both ends of the cooling tube
Through two side templates, and it is concordant with template outer surface.The free end of the external screw rod is positioned in template by nut.Institute
State at external screw free end, there is packing ring between nut and template.The packing ring is provided with water inlet in cooling tube correspondence position
And water outlet.
Further, the internal thread screw thread direction at described sleeve pipe both ends is opposite.
Having the technical effect that for the utility model is unquestionable：
1) wall can be cooled down by cooling tube, reaches the effect of control critical eigenvalue；
2) structural member degree of safety and durability requirements are met, it is ensured that wall waterproof quality；
3) external screw rod assembling and disassembling is simple and convenient, and engineering construction is efficient；
4) external screw rod and rubber round platform is reusable, cost-effective.

Embodiment
With reference to embodiment, the utility model is described in further detail, but should not be construed the above-mentioned master of the utility model
Topic scope is only limitted to following embodiments.It is common according to this area in the case where not departing from the above-mentioned technological thought of the utility model
Technological know-how and customary means, make various replacements and change, should all include within the protection scope of the present utility model.
A kind of new cooling sealing up screw, it is characterised in that：Including two external 2, two elastic rubber round platforms 5 of screw rod,
And it is connected to the casing 3 between two external screw rods 2.
The both ends of described sleeve pipe 3 are both provided with and the matched internal thread screw thread of external 2 external spiral screw thread of screw rod.The set
The internal thread screw thread direction at 3 both ends of pipe is opposite.The periphery of described sleeve pipe 3 is arranged with cooling tube 4.Wherein, adhesive linkage 6 has filled up set
Annular space between 4 inner surface of tube body of 3 outer wall of pipe and cooling tube, and reserve intake-outlet.The middle part of the cooling tube 4 is equipped with
Hydro-expansive rubber seal ring 1.
Axial hole is provided with the elastic rubber round platform 5.The axial hole runs through the both sides bottom of elastic rubber round platform 5
Face.Axial hole is stretched out at the both ends of the cooling tube 4, and two elastic rubber round platforms 5 are tightly sleeved in the both ends of cooling tube 4 respectively.
The elastic rubber round platform 5 can mortar leakage prevention, the effect as first layer waterproof.Middle hydro-expansive rubber seal ring 1,
It can play the role of second layer waterproof.
During work, template is close in the side of the elastic rubber round platform 5 away from casing 3.Two side templates are corresponded in cooling tube 4
Position is provided with water inlet and water outlet.The free end of the external screw rod 2 is positioned in template by nut.The external spiral shell
2 free end of bar, has packing ring between nut and template.The packing ring does not block the position of intake-outlet.
In the present embodiment, the cooling tube 4 includes liner layer 401, hollow layer 402 and outer shell 403.The hollow layer
402 are arranged between liner layer 401 and outer shell 403.Spiral deflector, spiral deflector are provided with the hollow layer 402
Uniform disk is connected on liner layer 401.In the concrete temperature rise period, water inlet and water outlet insertion are led with what aperture matched
Pipe, by high-strength hydraulic pressure, cooling water is passed through in water inlet, and the cooling water constantly flowed absorbs the heat that concrete produces, drop
Low concrete highest heating value, reduces temperature difference, controls temperature stress, limits concrete thermal cracking.
After concrete setting, remove that the lumps of wood on the outer two external screw rods 2 of wall is stupefied and template.Screw out external screw rod 2.Will
The elastic rubber round platform 5 being socketed on cooling tube 4 takes out.The external screw rod 2 and elastic rubber round platform 5 removed are reusable.
