Description
Technical field
The utility model relates to a kind of back of the body bolt, for all kinds of building dry-hung plate decoration, it is by plate back anchor connection, therefore claim " back of the body bolt ", be applicable to anti-vibration and require that higher building external envelope structure and anti-braking are impacted the dry hanging curtain walls such as subway station and used, be particularly useful for the use such as porcelain plate, devitrified glass, also can be used for other building structure field.The utility model also relates to the syndeton utilizing this back of the body bolt.
Background technology
At present, the existing screw-in back of the body bolt used in building external envelope structure curtain wall, its great advantage is that the expansion part head expansion bottom outlet bored behind with stone slab, porcelain plate etc. of punctuating forms the synchronous load of whole circle, and its disadvantage is that expanding plate load is too weak.Main cause is that the strength of the screw thread relying on screw rod to screw in is to strut expansion member, thick cannot to strut, so cause its expansion member to do very thin, its thread place only has an appointment 0.3 millimeter, therefore this sheet load is poor, also have because the uncontrollable screw rod of manual installation is screwed into the degree of depth, once be not screwed into the end will cause indentation pull-out when carrying negative blast, pushed up at the bottom of firm plate hole when being screwed into dark, when carrying positive wine pressure, top is worn, also have and can produce screw bolt loosening under the shake frequently of the positive and negative blast of annual 20-30 ten thousand times, so can only indoor be applicable to, as larger in being applied to outer curtain wall hidden danger, and cost is higher, in order to prevent thinner cannot tapping and cannot the demoulding, its Bian long cylinder first being gone out a hex nut+thicker by hot upsetting, after tapping, except expanded head, its outside machines away by whole section, secondary tapping after grooving, due to too thin, when secondary tapping and polishing, its waster amount is large, during securing member is produced, its waster is easy to escape from detection, future trouble is larger.And during mounting suspension member nutting, because screw rod is along with nut rotation, almost 100% all head at the bottom of plate, so hidden danger is larger.
Spacing in order to solve, there is another kind of screw-in back of the body bolt, spacing bead has together been established in its employing endoporus bottom, spacing from it solving on the surface, but violate gross error from mechanical major angle, because its load of screw-in back of the body bolt mainly relies on screw thread on expanding plate that bearing capacity is passed to screw rod by screw thread on screw rod.And screw thread tapping is because having established spacing bead in bottom, hole, to cause at least load section cannot by screw thread power transmission, and the crucial load place of this place expansion head just in time, so 4 sheet loads as thin as paper bottom thread can only be relied on, once bending tablet will be caused to rupture for expansion head load and head-bent skids off, what namely cannot carry the heavily loaded pulling force of stone slab and positive and negative blast bears power.
In addition, along with the impact of grabbing tighter and tighter on the duration with builing industry of soaring of China's labour cost, China is entering machine comprehensively and is replacing the artificial epoch, and the existing screw-in back of the body bolt, not only complex manufacturing, and prepackage and mounting process more complicated, time-consuming, cannot Auto-mounting be used.

The nut of described back of the body bolt adopts and presses solidly nut 4, the described nut that presses solidly is provided with and presses solidly deformation section 41, the described deformation section that presses solidly can be destroyed by above-mentioned instrument, and the screw thread position embedded on screw rod, and/or the screw thread position on destruction screw rod, and form the syndeton of never becoming loose, described in press solidly the profile of deformation section 41 consistent with the profile of described position point 23, also can operated by the instrument identical by the handheld tool operated position point 23.
Syndeton provided by the utility model, comprises the object 100(such as curtain wall panel arranging described expansion bottom outlet 101), the above-mentioned back of the body bolt that is connected with described object 100, described position point 22 is exposed to described expansion bottom outlet 101 aperture place.During operation, can be connected with position point 23 with the location structure on instrument or described electrical equipment or pneumatic equipment and maintain setting element 2, with the connector 10 of the swivel head connecting screw rod 1 on electronic or pneumatic tool, by rotary screw 1, screw rod 1 is screwed in expansion member 2, impulse stroke or spacing is controlled by automation equipment, make the end of screw rod 1 accurately can arrive the degree of depth of needs, expansion position 22 is expanded by screw rod 1 in this process, after expansion position 22 has been expanded, namely back of the body bolt is connected with object 100, then position point 23 can be destroyed with handheld tool, setting element 2 and screw rod 1 is made to form the entirety of never becoming loose.Described expansion bottom outlet mouth is counter bore structure 102, is placed with pad 500 in counter bore structure, and when making positive wine pressure, object 100 back is for the overall load of described back of the body bolt.
And then be inserted in fixture 300(such as suspension member at position point 23 place), also have the plane coordinated with position point 23 in the hole of ear hanging pieces, thus the anti-rotation forming fixture and expansion member is connected.
Then the nut 41 of back of the body bolt is inserted in screw rod, fastening, can deformation section be pressed solidly with handheld tool is broken, make nut 4 and screw rod 1 form the entirety of never becoming loose.
In addition, also can be provided with flexible boot outward in described expansion member, flexible boot is provided with tear fracture mouth at the adjacent expansion position of expansion member.
With reference to Fig. 1,3, in the present embodiment, the middle part of described screw rod 1 is provided with spacing section 11, and spacing section 11 is protruding or boss.Coordinate with the upper end of expansion member for spacing section 11, when the upper-end contact of spacing section 11 and expansion member, the bottom of screw rod 1 just arrives the extreme position at the bottom of hole, thus just can strut completely and support expansion position comprehensively, avoid institute's produced problem in background technology, prevent again bolt bottom from causing damage at the bottom of expansion bottom outlet hole.
With reference to Fig. 7, in the present embodiment, described nut 4 adopts conventional nut, and described had support zone by firmware part 300, and support zone is directly formed to support with the position, expansion bottom outlet 101 aperture of object 100 and coordinates.The other parts fundamental sum preceding sections of the present embodiment is identical, and drawing reference numeral is identical with Fig. 1-6 in the figure 7, represents identical implication.
With reference to Fig. 8, in the present embodiment, the upper end of expansion member 2 is provided with counterbore type step 201, spacing section of lower end in the middle part of screw rod 1 is sunk on described counterbore type step 201, counterbore type step arranged outside has position point 110, described position point is the location structures such as instrument otch, outer-hexagonal or other shape that may be used for input torque of surely turning, and with it as the spacing of aforementioned embodiments coordinates.Drawing reference numeral is identical with Fig. 1-7 in fig. 8, represents identical implication.
