The specific embodiment
Embodiment 1:
A kind of bolt sleeve embodiment, referring to Fig. 1, comprise a sleeve (bolt sleeve) 1 that can be inserted in bolt, have at least an end to be provided with the blister cavities 2 of projection to two ends at described sleeve outboard shafts, described blister cavities refers to the utricule of hollow, be full of in described blister cavities that foamed glue 2-1, described foamed glue are arranged is the building water-proof foamed glue, for example polyurethane foam glue.
Among the embodiment, referring to Fig. 2, described sleeve outboard shafts is provided with the catch 3 of projection to the centre, is respectively arranged with the blister cavities of projection to two ends at described sleeve outboard shafts, and blister cavities is threaded connection on sleeve, and the spinning in and out blister cavities is realized the adjusting of length sleeve.
Among the embodiment, described blister cavities is sealed balloon, comprise the joint face 2-2 that is connected with the sleeve endoporus with the vertical outer block face 2-3 that is connected that arranges of joint face one end, it is not yielding that wherein said joint face and outer block face all have some strength, for example be thickness greater than the plastic products of 1mm, outer block face outer end and the joint face other end have been connected to form sealed balloon by flexible material 2-4; Described flexible material is plastic flexible plastic (for example thickness is less than the plastics of 0.5mm), rubber or thickness less than 0.2 millimeter metal thin skin.
During use, can the inboard joint face of blister cavities be poked with brill or hard material, impel foamed glue to flow out and block the bolt hole of extracting bolt out, also can a perforate be set at the inboard joint face of blister cavities, perforate at ordinary times by a diaphragm seal that is easy to tear firmly.
Among the embodiment, for the ease of the subsequent treatment after the bolt extraction, for example need to remove the upper cement of surperficial a part of foamed glue filling floating, therefore, the hole wall diameter at blister cavities place, sleeve endoporus two ends is greater than diameter of bore in the middle of the sleeve.
Embodiment 2:
A kind of waterproof through-wall bolt device embodiment for shuttering supporting, referring to Fig. 3, described device includes a bolt 4 that is used for support shuttering, described bolt shaft is overlapped laterally embodiment 1 described bolt sleeve, described bolt sleeve arranges bossed catch vertically, have at least the bolt sleeve of a side to be provided with blister cavities in described catch both sides, being full of in described blister cavities has foamed glue.
Described as embodiment 1, described blister cavities is sealed balloon, blister cavities comprise the joint face that is connected with the bolt sleeve endoporus with the vertical outer block face that is connected that arranges of joint face one end, it is not yielding that described joint face and outer block face all have some strength, for example be thickness greater than the plastic products of 1mm, outer block face outer end and the joint face other end have been connected to form sealed balloon by flexible material 2-4; Described flexible material is plastics, rubber or thickness less than 0.2 millimeter metal thin skin, such as aluminium skin etc.
Among the embodiment, for the ease of processing and making, described bolt sleeve is the plastic products that form with die casting, and the inboard cover of bolt sleeve has screw thread, and bolt sleeve and bolt are threaded connection together.
Among the embodiment, in order to strengthen the anti-pervious function of bolt sleeve, described catch arranges perpendicular to the bolt sleeve surface, and the height of catch is 2 centimetres at least.
