Description
Technical field
Exterior wall pouring construction technical field is the utility model is related to, more particularly to it is a kind of permanently cast-in-place for vacuum heat-insulation
The water-proof bolt of template.
Background technology
The state basic policy that green energy conservation assembled arthitecutral structure system is state fundamental construction is promoted, at present steel reinforced concrete shearing force
Wall construction exterior enclosure wall is most using the materials such as styrofoam, graphite polystyrene board, in recent years, China's energy saving building and wall thermal insulating skill
Art is also developed rapidly, designed at present invented a kind of light weight, high insulating effect, easy for construction, fire protecting performance is good,
Without potential safety hazard, the permanent cast-in-place concrete composite heat preservation moulding board with building with the life-span.This kind of permanent cast-in-place concrete
Compound heat preservation die plate, without removing, reduces form removal process, reduces work output, shorten the cycle after the completion of wall pours.
But this class template when pouring in order to avoid coagulation earth lateral pressure, usually using template screw rod by two pieces of template tightenings, treat
Extraction screw rod is needed to be in the milk screw hole after the completion of pouring.The concrete strength of grouting is low, and impermeability is poor, in screw hole
Immersion phenomenon easily occurs for place.
Utility model content
The purpose of this utility model be in order to solve shortcoming present in prior art, and the one kind proposed be used for vacuum every
The water-proof bolt of hot permanent cast-in-situ template.
To achieve these goals, the utility model employs following technical scheme：
A kind of water-proof bolt for the permanent cast-in-situ template of vacuum heat-insulation, it is characterised in that：Including intermediate bar, in centre
Bar both ends are equipped with screwed hole, and middle socket seal ring, a pull bar is threadedly coupled in each screwed hole on the outside of intermediate bar,
Pull bar both ends are equipped with external screw thread, and the screwed hole of external screw thread corresponding thereto is correspondingly arranged, and drawing is also threadedly coupled in pull bar one end
Tight nut.
Preferably, the seal ring is water-swellable sealing collar.
Preferably, screw thread mating connection seal receptacle is gone back on the external screw thread of described pull bar one end, seal receptacle is circular ring structure,
End face groove is provided with one of end face of seal receptacle, end face groove is set towards intermediate bar, is connected at end face groove close
Mounting.
Preferably, also it is socketed the frustum of a cone in the pull bar other end.
The utility model has the advantage of：One kind provided by the utility model is used for the permanent cast-in-situ template of vacuum heat-insulation
Water-proof bolt use three stage structure, convenient installation, the pull bar at both ends can be used in turn, and saved material, covered on intermediate bar
Connect seal ring, can water-swellable, can effective sealing, protective layer is provided with the outside of the water-proof bolt, can effectively prevent to stop
Timber bolt produces chemical reaction with concrete, influences the intensity, rigidity and its stability of cement.
