Abstract
Steel silo Special seal structural bolts, assembling steel plate storehouse because of its speed of application fast, cost is low, is widely used as all roll-overs and uses, but cannot solve leakage problem because of bolt, and steel silo can not be airtight, therefore cannot long-term storage.The development that this problem hinders assembling steel plate storehouse technology extends, and becomes a large technical bottleneck of silo industry.The utility model comprises: nuts (1), and described nuts connects ladder shelves shoulder (2) of sealing, and described ladder shelves shoulder connecting stud (3), described stud is M10-16, stud length 15-50mm.The utility model is used for the steel silo of the airtight requirement of tool.
Description
Technical field
the utility model relates to a kind of steel silo design aiming at the airtight requirement of tool, has bolt or the nut of airtight construction.
Background technique
long-term deposit silo, because of needs fumigant insect killing, must have certain tightness, and only in guaranteed storehouse, medicament reaches finite concentration and is just enough to kill off the insect pests.Airtight simultaneously due to steel silo, can ensure that in storehouse, medicament does not leak, free from environmental pollution, does not produce harm to human body.
assembling steel plate storehouse because of its speed of application fast, cost is low, is widely used as all roll-overs and uses, but cannot solve leakage problem because of bolt, and steel silo can not be airtight, therefore cannot long-term storage.The development that this problem hinders assembling steel plate storehouse technology extends, and becomes a large technical bottleneck of silo industry.
Summary of the invention
the purpose of this utility model is to provide a kind of bolt having the assembling steel plate storehouse of seal request to use.
the purpose of this utility model is achieved in that
a kind of steel silo Special seal structural bolts, its composition comprises: nuts, and described nuts connects ladder shelves shoulder, and described ladder shelves shoulder connecting stud, described stud is M10-16, stud length 15-50mm.
described steel silo Special seal structural bolts, described ladder shelves shoulder, in bulkhead plate side, is equipped with sealing joint strip.
described steel silo Special seal structural bolts, the smaller diameter end of described ladder shelves shoulder is towards described stud side, and as sealing support end, described sealing support end has seal ring towards described stud side and withholds groove.
described steel silo Special seal structural bolts, described major diameter one end of ladder shelves shoulder and the annular of the cross-sectional direction of central vertical are seal face, and its external diameter is 1.5-3 times of stud diameter, and thickness is 1-3mm.
described steel silo Special seal structural bolts, minor diameter one end diameter of described ladder shelves shoulder is less than major diameter one end 4-10mm of described ladder shelves shoulder, and thickness is 1-4mm.
described steel silo Special seal structural bolts, major diameter one end of described ladder shelves shoulder has back pressure cone.
beneficial effect:
sealing configuration special bolt of the present utility model has ladder shelves shoulder, after being connected with bulkhead plate, forming fixed opening sealing dedicated slot, after using the pressure sealing of cement sealing material, bulkhead plate and stud, bulkhead plate and shelves are takeed on and are formed dual face seals, colloid is embedded in seal groove, difficult drop-off, sealing effect is ideal, airtight requirement is fully meet through inspection, the steel silo tread flaking of short-term week conversion is made to become long-term storage type container, for brick is mixed the overall conversion upgrading plan to steel structure silo of silo by national requirements, provide technical foundation.
sealing support end withholds groove with seal ring, and in groove, sealing can be taked to be different from the another kind of material sealing material that grade shoulder seal uses material, and entirety forms two kinds of material double-layer sealing structures, guarantees sealing effect.
when being stud diameter 1.5-3 times through overtesting larger diameter end ladder shelves shoulder diameter, integral sealing effect is best, and bolt manufacture cost is both economical.1-3mm thickness is optimal economic size under the prerequisite of guarantee shelves shoulder intensity.
ladder shelves shoulder size diameter end diameter difference is at 4-10mm, and thickness is when 1-4mm scope, and major diameter shelves take on the most applicable operation of spill colloid fill area formed with silo wallboard.
ladder shelves shoulder major diameter side is bored with back pressure, can strengthen the intensity of shelves shoulder, and be convenient to forging molding.
bolt outside steel silo is exposed to for stud, adopts annular shelves to take on nut and nut and bulkhead sheet separation can be made to be sealed.
accompanying drawing illustrates:
accompanying drawing 1 is the structural representation of bolt of the present utility model.
accompanying drawing 2 is left views of accompanying drawing 1.
accompanying drawing 3 is working state figures of bolt of the present utility model.
the another kind of working state figure of accompanying drawing 4 bolt of the present utility model.
