Abstract
The utility model discloses a plug type cock with ringy embedding groove. Two or more rib plates which are arranged on the outside of the plug type cock to be evenly disposes along the circumferential direction. A press disk is provided at the tail of the plug type cock. A metallic core is fixed in the plug type cock. A Rhabditis-form embedding section is provided at the front part of the plug type cock. Several ringy embedding grooves are axially arranged on the surface of the embedding section. The end of the embedding section is conical. The rib plate stretches from the press disk to be connected with the embedding section. The conical end of the embedding section of the plug type cock and the blade of the outside edge of the rib plate facilitate the insertion of the plug type in the heat insulating plate. The ringy groove on the embedding section of the plug type cock makes the plug type cock in constant and reliable connection with the cement wall to satisfy the requirements to the plug type cock for bearing the surface decorative layer of the wall. Moreover, the notch which is left for the supporting metal core during the injection is positioned in the sleeve of the plug type cock by the arrangement of a core rod, so as to eliminate the heat bridge in the notch to ensure an effective heat insulation of the heat insulating layer.
Description
Technical field
The utility model relates to a kind of grafting bolt that has the ring-type caulking groove.
Background technology
During insulation outside the existing building body of wall is handled, adopt the bloated bolt of nylon to do the anchoring piece of heat-insulation plate for external and body of wall usually.The expand tube termination of this anchoring piece is the spherical insertion warming plate that is difficult for of semicircle; During fluid concrete, because the effect of concrete lateral pressure is easy to generate the crooked fixed effect that influences, the fastness that combines with concrete is relatively poor in addition; Nylon expand bolt the expand tube bending rigidity less, be easy to generate distortion; The expand tube and the warming plate contact area of the bloated bolt of nylon are less, so relatively poor to the support of warming plate.
The utility model content
The purpose of this utility model is to provide a kind of grafting bolt that has the ring-type caulking groove for overcoming above-mentioned deficiency.This grafting bolt is easy to insert warming plate and has improved it and the anchoring strength of concrete wall.
The utility model is achieved in that a kind of grafting bolt that has the ring-type caulking groove, and grafting bolt outside is provided with circumferentially uniform fin of at least two edges, and grafting bolt afterbody has platen; Be fixed with metal-coredly in the grafting bolt, grafting bolt front end is provided with shaft-like interlocking section, and the interlocking section surface is provided with the several ringlike caulking groove vertically, and an interlocking section termination is made as taper, fin vertically from platen always the section of extending to and rabbet join.
Further, the grafting bolt is made of sleeve and core bar, the axial length of fin is identical with sleeve, core bar is inserted in the sleeve, and fix by helicitic texture or draw-in groove structure, metal-cored being arranged in the core bar, the core bar afterbody is provided with concentric counterbore, the thread segment of metal-cored afterbody is positioned at counterbore, the core bar tail end flushes with platen, and the sleeve afterbody is provided with the axial fastening structure that matches with the core bar tail end, core bar and metal-cored being made into integration, core bar inserts behind the sleeve its front end exposed portions serve and constitutes the described shaft-like interlocking of grafting bolt front end section, is positioned at sleeve for supporting the metal-cored technology breach that forms during injection moulding on the core bar.
Further, described fin radially is blade-like in the outer.
Further, described fin vertically integral body be taper.
Further, described fin extends from platen along grafting stud shaft line parallel, is becoming taper near interlocking section place.
The interlocking section termination of grafting bolt is made as after taper, fin outer be blade-like, is beneficial to the grafting bolt and inserts warming plate, saved the correspondence processing that warming plate is done for inserting warming plate, reduced processing cost; On the interlocking section that grafting is fastened, be provided with annular groove, make grafting bolt and concrete wall form reliable and stable being connected, thereby satisfy the load bearing requirements of grafting bolt the wall body surface decorative layer by this annular groove; Because the grafting body can be installed expanded metal lath in screed, compare with gauze wire cloth, has strengthened surperficial cracking resistance.In addition, for after supporting the metal-cored technology breach that forms and being located in the grafting bolt sleeve, eliminated the heat bridge that forms because of this breach effectively during with injection moulding, guaranteed effective insulation of insulation layer by the mode that core bar is set.

The specific embodiment
Further specify the utility model below in conjunction with drawings and Examples.
Embodiment 1, and the outside that has the grafting bolt (see figure 1) of ring-type caulking groove is provided with circumferentially uniform fin 3 of four edges, and grafting bolt afterbody has platen 1; Be fixed with metal-cored 7 (see figure 2)s in the grafting bolt, grafting bolt front end is provided with shaft-like interlocking section, and the interlocking section surface is provided with five ring-type caulking grooves 4 vertically, and an interlocking section termination 5 is made as taper, fin vertically from platen always the section of extending to and rabbet join.The grafting bolt is made of sleeve 2 and core bar 8, and the axial length of fin is identical with sleeve, and fin, platen and sleeve are injected into one.Core bar is inserted in the sleeve, and is connected and fixed by screw thread and sleeve.Metal-cored being arranged in the core bar, both cast out at one; Be positioned at sleeve for supporting the metal-cored technology breach 6 that forms during injection moulding on the core bar; The core bar afterbody is provided with counterbore 9, the thread segment of metal-cored afterbody is positioned at counterbore, and the core bar tail end flushes with platen, and the sleeve afterbody is provided with the axial fastening structure that matches with the core bar tail end, be the cone that the taper hole of sleeve tail end can stick the core bar tail end, realize axial limiting.Four fins integral body vertically are taper.Each fin radially outer 10 is blade-like.The assembling annexation of grafting bolt and body of wall as shown in Figure 4, utilize the outer of the blade-like of the cone-shaped end of interlocking section of grafting bolt and each fin pass the polyphenyl material warming plate 12, its part that passes warming plate casts from 11 li of concrete walls, and the platen 1 of grafting bolt tightly sticks warming plate; Along the traditional thread binding U-shaped packing ring 13 of grafting stud shaft, the U-shaped packing ring can make between expanded metal lath and the warming plate and maintain a certain distance in the outside of platen; At U-shaped packing ring outside cartridge plate net 15, expanded metal lath is arranged in screed 14, and expanded metal lath can strengthen the surperficial crack resistance of facing mortar layer; Next adorns an open washer 16, refills long nut 17 at last, and long nut and metal-cored afterbody are by being threaded, and long nut is arranged in the counterbore 9 of core bar afterbody.
Embodiment 2, and cylindricality is formed at four fin rear portions 18 of present embodiment, and anterior 19 are the taper (see figure 3).Compare with embodiment 1, this grafting bolt has further increased and warming plate and concrete wall contact area.
