Abstract
The utility model relates to a protective bolt, in particular to an expansion bolt. The protective bolt can not be rusted inside a wall body or outside the wall body, and enable rainwater not to penetrate into the protective bolt from a protective bolt hole. The protective bolt comprises a screw rod and a screw cap, wherein an expansion sleeve is arranged on the screw rod; the screw rod, the screw cap and the expansion sleeve are set into the stainless type or zinc plating stainless type; a convex rubber gasket, a concave metal gasket and a flat metal gasket are arranged outside the expansion sleeve in sequence; and an elastic metal gasket is arranged on the inner side of the screw cap. In the utility model, the protective bolt is made of stainless materials, and the expansion sleeve and the screw cap are all provided with the protective gaskets, so that the rusting and corrosion phenomena of the protective bolt are completely prevented, the wall body and a heat-insulating layer can not be damaged, and the effects of avoiding from polluting the attractiveness and the harmony of the wall body are achieved.
Description
Technical field
The utility model relates to a kind of fender bolt, specifically, relates to a kind of EXPANSION ANCHOR BOLTS.
Background technique
Present protective grating window, hanging outdoor unit of air conditioner, (metal is pre-buried for lightning protection system, after bury reinforcing bar branch bar), Outdoor clothes airing rack is fixed, the fixing grade of roofing solar energy we can say that the personal inclination with the owner makes arbitrarily, install, make the external facade in script building attractive in appearance extremely inharmonious, and expansion fender bolt of the prior art generally all comprises screw rod, nut, expansion sleeve, expansion sleeve is provided with the outside of screw rod, these parts all are to make with iron, iron gets rusty easily especially, infringement and pollution to the building body are very serious, because the guard rail that the owner is installed additional and fixedly air conditioner support all be with at present common EXPANSION ANCHOR BOLTS around window opening and body of wall fixing with, this just makes, and original thermal insulation layer is destroyed have been fallen, simultaneously because thereby the very fast corrosion under the state of wind and weather of its EXPANSION ANCHOR BOLTS causes the body of wall layer, cement layer, the thermal insulation layer accelerated ageing was lost efficacy, the body of wall layer also descends because of water inlet makes cement setting power, thereby the house has caused heavy damage carelessly because of ours, reduced the working life in house, and more and more serious rusty stain makes also the outer facade of body of wall seriously polluted.
Summary of the invention
The utility model overcomes above-mentioned defective, provides a kind of installation back can not get rusty in body of wall He outside the body of wall, and rainwater can be from the fender bolt of fender bolt hole infiltration yet.
The technological scheme of fender bolt of the present utility model is such: it comprises screw rod, nut, and expansion sleeve is set on the screw rod, and screw rod, nut and expansion sleeve are set to stainless steel or zinc-plated stainless steel type screw rod, nut, expansion sleeve; Expansion sleeve sets gradually protruding Rubber washer, indent metallic shim, metal plain cushion outward, and the inboard of nut is provided with flexible metal gasket.
Expansion sleeve outer installment cross gap, the corresponding cross gap of screw rod outer tip end is provided with cross recess.
The arranged outside plastic cap nut of nut.Get final product as installing supporting prolongation metalwork additional as lightning-arrest fixing branch bar.
Fender bolt of the present utility model, owing to used stainless steel material, and all be provided with the protection pad at expansion sleeve and nut, so prevented the corrosion phenomenon of fender bolt fully, do not destroy body of wall and thermal insulation layer, reach the effect of not polluting body of wall coordination attractive in appearance.
Description of drawings
Fig. 1 is a disassembly diagram of the present utility model.
Embodiment
It comprises screw rod 1, nut 8 fender bolt of the present utility model, and expansion sleeve 2 is set on the screw rod 1, and screw rod 1, nut 8 and expansion sleeve 2 are set to stainless steel or zinc-plated stainless steel type screw rod 1, nut 8, expansion sleeve 2; Set gradually protruding Rubber washer 4, indent metallic shim 5, metal plain cushion 6 outside the expansion sleeve 2, the inboard of nut 8 is provided with flexible metal gasket 7.Expansion sleeve 2 outer installment cross gap 3, the corresponding cross gap of screw rod 1 outer tip end is provided with cross recess.The arranged outside plastic cap nut 9 of nut 8.
At first with power to 8 on the EXPANSION ANCHOR BOLTS, 9 one-tenth, nut 8, pad are laid down the expansion sleeve 2 that has cross recess up to exposing in use, protruding Rubber washer 4, indent metallic shim 5 package successively targetedly, again with institute's fixture, metallic elastic pad 7 again; Tighten nut 8 at last and exterior nut cap 9 gets final product.The present on year-on-year basis length of the spiro rod length of this upset bolt will increase to some extent, to reserve raised rubber, the space of groove metallic shim, the protective grating window is being installed, hanging outdoor unit of air conditioner, lightning protection system (replace pre-buried by suggestion, after bury metal reinforcing bar branch bar), roofing solar energy is fixed when waiting, at first the metalwork of EXPANSION ANCHOR BOLTS is to adopt stainless steel or stainless material such as zinc-plated to form, install aging-resistant rubber layer pad again additional, outside it, install plastic cap nut after the use again on the terminal screw additional and protected, use EXPANSION ANCHOR BOLTS both to reach not corrosion like this at window hurdle and air conditioner support, do not destroy body of wall and thermal insulation layer, reach the effect of not polluting body of wall coordination attractive in appearance.This bolt is used general in related domain.
