Description
Technical field
The present invention relates to a kind of expansion bolt, a kind of expansion bolt with stability.
Background technology
Now with expanding economy, the building of the south of the lower reaches of the Yangtze River is also required to Winter heat supply summer cooling, but the typically no heat-insulation layer of former building is arranged, like this, the consumption of the heating and cooling of building is very big, therefore uses now for the old building not having heat-insulation layer and lays heat-insulation layer outside metope.Current heat-insulation layer typically uses metal or fleece outsourcing, is fixed on exterior wall with expansion bolt, and lays heat-insulation layer in metal or fleece, owing to exterior wall can be affected by blast, when malleation, metope is pressed inward, and during negative pressure, metope is pulled outside, the most common expansion bolt can be pulled loose at leisure, until being drawn out, whole metope can be caused to be blown off, news report often occurring, large area insulating layer of external wall is blown off, and the most also can cause the casualty accident of personnel.And entangle its reason, be exactly mainly existing expansion bolt structure institute extremely, the expanding block of the inverted cone bottom existing expansion bolt is unsettled, it is exactly that whole expansion bolt is in mobilizable state, once metope is affected by blast, will result in expansion bolt and is repeatedly drawn out press-in, presents a vibrational state, being computed, the expansion bolt of insulating layer of external wall has the vibration of thousands of times for one day.Just think, the most how gathering of more how fixing, existing expansion bolt, under the vibration of such high intensity, is certain to be drawn out.The most urgently improve the structure of existing expansion bolt, the problem that can loosen with solution with expansion bolt.
Summary of the invention
Present invention aim to address that in prior art, expansion bolt is in the problem being easily vibrated pull-out existing for movable state in the borehole, it is provided that a kind of expansion bolt with stability.The present invention designs a kind of expansion bolt with stability, including key, it is characterized in that: the bottom of key is fixing connects a screw rod, external screw thread is offered on screw rod, in the bottom of screw rod, set is rotary with expansion reverse taper, the screw rod expanding above reverse taper is cased with expansion tube, top at the bottom of screw rod is provided with left-hand thread, have a reverse stator by the left-hand thread twist-on arranged on top at the bottom of left-hand thread and screw rod.In the top screws of expansion tube, twist-on has a rotating gasket.Expansion tube lateral surface is provided with the anti-rotation steady pin of evagination.Upper end edge at key axially offers interior counterbore, and interior counterbore is provided with screw thread, this screw thread and fixing bolt twist-on.Upper end edge at key axially has an overhanging threaded rod.It is an advantage of the invention that expansion bolt is fixing after piercing, through installation, it is possible to keep stability.
Accompanying drawing explanation
Accompanying drawing 1 is the section of structure of the present invention.
Fig. 2 is another section of structure of the present invention.
Detailed description of the invention
A kind of expansion bolt with stability in figure, including key 1, it is characterized in that: the bottom of key is fixing connects a screw rod 2, external screw thread 3 is offered on screw rod, it is rotary with expansion reverse taper 4 at the bottom of screw rod set, the screw rod expanding above reverse taper is cased with expansion tube 5, top at the bottom of screw rod is provided with left-hand thread 6, have a reverse stator 7 by the left-hand thread twist-on arranged on top at the bottom of left-hand thread and screw rod.In the top screws of expansion tube, twist-on has a rotating gasket 8.Expansion tube lateral surface is provided with the anti-rotation steady pin 9 of evagination.Upper end edge at key axially offers interior counterbore 10, and interior counterbore is provided with screw thread, this screw thread and fixing bolt twist-on.In another embodiment, the upper end edge at key axially has an overhanging threaded rod 11, is used for and fixing nut twist-on.
nullWhen needs beat expansion bolt on body of wall，First can lean on good installing hole on body of wall，Then the expansion bolt of the present invention is put in hole，Tap expansion bolt outer end gently，Reality is struck by inside expansion bolt，Contact with the bottom surface of boring，Then key 1(instrument twist-on is rotated in the interior counterbore of expansion bolt with instrument)，Now，The expansion reverse taper of the bottom set rotation of screw rod moves along screw rod，Expansion tube on expansion bolt is inflated reverse taper and struts，Good in the hole inner position laying expansion bolt together with expansion tube and expansion reverse taper，And the key in outside just with boring tolerance fit，The outside of expansion tube also fixes，Owing to being provided with left-hand thread on top at the bottom of screw rod，When that rotates key, reverse stator will not be outer mobile，But shift to inner side，The bottom of expansion bolt has a reverse stator to sit the end in boring the most in fact，Drill hole inner wall is withstood by expansion tube and expansion reverse taper in middle part，Outside relative with boring empty wall by key，That expansion bolt is that interior China and foreign countries are each attached to bore in the air，If when installing expansion bolt，Some solidification glue are irrigated in boring，After expansion bolt is put into, then solidify glue can reversely overflow，Fixed expansion bolt in boring，And the anti-rotation steady pin of the evagination arranged on expansion tube lateral surface can ensure that when rotating key，Expansion tube will not concomitant rotation，Ensure strutting of expansion tube.
When installing the grid of heat-insulation layer, as long as by fixing bolt or fixing nut twist-on on expansion bolt.
