Description
Technical field
The utility model relates to a kind of flexible bell and spigot joint iron drain-pipe anticreep clip, and it belongs to a kind of device for building iron drain-pipe pipeline joint anticreep.
Background technique
Used in construction drainage the most frequently used at present flexible bell and spigot joint cast iron tubing is a kind of pipe joint socket joint, and adopts the tubing of O-ring seal, flange and bolt presses interface Placement.This tubing is safe in general construction drainage Pipe installing.But bear comparatively mass-flow gravity, impact force and mechanical force pipe joint position at the rain drainage pipe of some pressure-bearings with some, often occur the phenomenon that pipe joint comes off.This not only uses to Pipe installing and brings potential safety hazard, also have impact on the application of flexible bell and spigot joint cast iron tubing on tall building storm sewer.
Outer the selecting of rain-water drainage tubing of architecture indoor is the large problem affecting construction quality.According to engineering discipline requirement, rain drainage pipe must carry out overflowing water experiment after installing.As the rain-water drainage standpipe of tall building, when overflowing water experiment, riser bottom can bear larger hydraulic pressure, and floor is higher, and pressure is larger.The outer rain-water drainage tubing of current architecture indoor mainly adopts plastic tube, cast iron tubing and steel pipe.Plastic tube because bearing capacity is poor, not ageing-resistant and sunlight exposure, fragile under low temperaturely to split, very short for working life for storm sewer; Though steel pipe has good bearing capacity, corrosion-resistant, also have influence on the working life of pipeline.Having flexible bell and spigot joint iron drain-pipe material is optimal rain-water drainage tubing, and it is ageing-resistant, corrosion-resistant, low noise, anti-seismic performance are good, long service life.But because it adopts the Placement of flexible interface, interface bearing capacity can only reach 0.35MPa, cause this tubing can only be used for the building roof rain drainage pipe of below 35 meters of height, greatly limit the Applicable scope of iron drain-pipe.In addition, discharge the position of horizontal main turning at architecture indoor drainage pipe soil stack to bottom, due to impact force and the horizontal dry in-pipe flow Action of Gravity Field of standpipe current, often easily occur that cast iron tube flexible interface comes off and cause leakage water problem.
Summary of the invention
The purpose of this utility model be solve pipe joint that existing iron drain-pipe exists easily come off cause leak, the low and non-serviceable technical problem of high-rise building of bearing capacity, provide a kind of and prevent iron drain-pipe from coming off, bearing capacity is high, join strength good and the flexible bell and spigot joint iron drain-pipe anticreep clip that high-rise building can be made to use.
The utility model is solve the problems of the technologies described above the technological scheme adopted to be:
A kind of flexible bell and spigot joint iron drain-pipe anticreep clip, comprise locking screw screw bolt and nut, wherein, it also comprises anticreep clip, described anticreep clip is at least made up of two panels clip monolithic, and described clip monolithic is the circular arc groove body with locking teeth, and locking teeth is located at the two ends up and down inside circular arc groove body, be provided with locking clamp ear in the both sides of circular arc groove body, be provided with fixing card ear at the middle part of the external side of circular arc grooved.
Described locking teeth is saw shape locking teeth, trapezoidal locking teeth, cone locking tooth or any one for increasing in other antiskid lock locking structure of surface friction drag.
Described fixing card ear is provided with oblong hole.
Described locking clamp ear is provided with circular port.
Described clip monolithic adopts steel plate punched shaping.
Because the utility model have employed technique scheme, utilize the structural feature of flexible bell and spigot joint iron drain-pipe material interface and existing clamping bolt, the utility model and socket flange are connected into an entirety.Simplify the linkage structure of anticreep clip.The utility model anticreep clip is fixed on card ear and is adopted long-round-shape fixing threaded hole, so that tube outer diameter size generation deviation, can radial displacement during anticreep locked clip device, and make locking teeth fully contact locking with outer pipe wall.The utility model adopts multiple monolithic composite structure, is convenient to the concentricity from Row sum-equal matrix Anti-release clamp hoop and tubing, makes it locking teeth and tube surfaces can be agreed with well.Multiple monolithic composite structure also makes the interface through reinforcing have certain elasticity.To resist the impact of pipe deforming docking port.Therefore, compared with background technique, the utility model has following advantages:
1, have that structure is simple, compact dimensions, easy for installation, be applicable to mass manufacturing, produce the advantages such as installation cost is cheap.For project installation, not only can save installing space, also can save construction cost in a large number, improve the Security of pipe joint.
2, interface bearing capacity is high, has brought up to 1.2MPa from 0.35MPa.The building roof storm sewer construction and installation requirement of below 120 meters of height can be met.
3, the utility model can also be used for the reinforcing installation that flexible bell and spigot joint iron drain-pipe suspends horizontal branch pipe interface in midair.Save Pipe installing and hang support.Improve the reliability of pipe joint.
