Description
Technical field
The present invention relates to a kind of large sized spiral double-fold occlusal tank intensity stiffening device and method, application diameter 15m is above, above, the volume 3000m of height 16m
3More than, or diameter 30m is above, above, the volume 6000m of height 6m
3Above tank body.
Background technology
The spiral double-fold occlusal technology is work hardening principle and the thin shell structure principle of utilizing in the Metal Forming, by the special technology and equipment steel plate that 2.0～4.3mm is thick (or high strength galvanized steel plate), adopt " spiral, two-fold limit, seaming " technology to build tank body.The tank body that adopts this kind technology to build has sizable hoop tensile strength, can bear the hoop tension that tank interior liquid produces.And this kind technology has advantages such as short construction period, cost is relatively low, quality is better.Be subjected to the interlock process limitation, build steel plate that spiral double-fold occlusal tank adopts at present and roll and the thicklyest can not surpass 4.3mm, thereby the tank body maximum volume also can only be accomplished 6000m
3About.When the tank body ratio of height to diameter surpassed 1, the volume maximum can only be accomplished 3000m
3When surpassing above-mentioned volume, because it is bigger to bear pressure, the distortion of double-fold occlusal influential point of tendons, the bulging distortion can appear in the bottom tank skin.
Summary of the invention
The technical issues that need to address of the present invention are that the large sized spiral double-fold occlusal tank intensity that adopts technological means that existing technology is built carries out the part and strengthens, and stops and reduce the bulging distortion of bottom tank skin and interlock muscle.
Another technical matters that the present invention need solve is that a kind of installation method of stiffening device is provided.
The technical solution adopted for the present invention to solve the technical problems is: adopt a reinforcement of the jar outside or a jar inboard reinforcement dual mode that spiral double-fold occlusal tank is carried out intensity and strengthen.
Large sized spiral double-fold occlusal tank intensity stiffening device of the present invention, the tank body of a band spiral double-fold occlusal muscle, it is characterized in that in tank body or outside some vertical shaped steel are arranged, be connected with some clips on the vertical shaped steel and fix, or vertical shaped steel uniformly-spaced welds with a jar inwall with horizontal double-fold occlusal muscle.
Stiffening device can have multiple scheme.
One of preferred, on the tank skin between the double-fold occlusal muscle of described tank body middle and lower part, being arranged with stiffening band spirally, the two ends of stiffening band are individually fixed on the same vertical shaped steel; Limit of described vertical shaped steel and horizontal double-fold occlusal muscle near.Wherein respectively there is fixed block at the stiffening band two ends, have the bolt top to be stuck on the same vertical shaped steel on it.
Preferred described reinforcement bandwidth 30～80mm, thick 2～3mm, winding height 1～3m at the bottom of jar.
Since stiffening band because of the hoop tension of self can be tightly around the tank skin outside, thereby stoped the bulging of tank skin between the double-fold occlusal muscle effectively, the bearing capacity of whole tank body and stability are enhanced.
Preferred two, be periphery around the described tank body some vertical shaped steel and with the double-fold occlusal muscle near, be connected with some clips on the every vertical shaped steel and the double-fold occlusal muscle is fixed.Preferably on vertical shaped steel, be provided with the V-arrangement lacing wire.
Since the double-fold occlusal muscle both be subjected to vertical shaped steel near, fixed by the clip on the vertical shaped steel again, be positioned at firmly on the vertical shaped steel, stressed effect is fairly good, has effectively stoped the loosening distortion of double-fold occlusal muscle.If on vertical shaped steel, tiltedly drawn the V-arrangement lacing wire again, then stoped the deformation better effects if.
Preferred three, some vertical shaped steel is periphery and is close to inner tank wall, and all there is weld nugget on the shaped steel both sides, and weld nugget is between two circle double-fold occlusal muscle.Spacing between preferred two vertical shaped steel is 0.5～3m.
Shaped steel supports and horizontal double-fold occlusal muscle formation cellular structure longitudinally, and this cellular structure has strengthened the bearing capacity and the stability of tank body bottom.
As preferably, vertical shaped steel is channel-section steel or angle steel, one (or two) bar limit of angle steel (or channel-section steel) be used for the double-fold occlusal muscle near, the simplest and reliable.
One of preferred Unit Installation method is characterized in that:
1) outer vertical shaped steel of predetermined fixed of tank body;
2) winding stiffening band spirally on tank wall is stuck on the same vertical shaped steel bolt top of the fixed block at stiffening band two ends;
3) tight a bolt gradually, stiffening band is close on the tank skin;
4) tighten on the vertical shaped steel all that clips are fixed on the double-fold occlusal muscle, finish installation.
The invention has the beneficial effects as follows: the bottom intensity of spiral double-fold occlusal tank is strengthened, thereby whole bearing capacity of tank body and stability are improved.Make and build diameter 15～50m, volume 4000～10000m
3Single tank body become possibility.
