A slot hole or a bolt head for revolving installation is arranged at an end of the straight bar. The utility model is characterized in that: a bush, the internal margin of which is equipped with an internal screw thread for matching the external screw thread of the anchor bolt, is mounted on the claw-shaped bolt sleeve. The external margin of the bush is in straight barrel shape. An anchoring claw extends from the front end of the bush, and a flute-shaped gap for installing is axially installed at the back end of the bush. The proposal relates to an anchoring fitting for curtain wall plate decoration, in particular to the back bolt, which can be universally used in the same hole diameter and different buried depths, overcoming the shortage that the existing back bolt cannot be commonly used in the same bole diameter and different buried depths.
Description
Technical field
The utility model relates to a kind of curtain wall panel fixed mechanism, is specifically related to the back of the body bolt in the curtain wall panel post-cut anchoring mechanism.
Background technique
Along with the development of building decorating industry, the outward appearance of City Building is not only pursued moulding, and more building begins to pay attention to attractive in appearance, the practicality and the environmental protection of decoration of exterior wall, so curtain wall panel is adopted by increasing building constructor.The City Building curtain wall uses dalles such as slabstone, ceramic plate or crystallite slabstone more at present, and its means of fixation adopts the post-cut anchoring to install more.Post-cut anchoring installation will get out similar earlier at the dalle back
The blind hole of shape is used special-purpose back of the body bolt and L type anchor pole that sheet material is hung then and is installed on the exterior wall of building, and wherein, L type anchor pole is used for hanging sheet material, and the effect of back of the body bolt then is the boring position that L type anchor pole is fixed on the sheet material back side.
Chinese patent CN2711439Y (" the detachable rotary back of the body is fastened ") has proposed a kind of back of the body bolt of new-type structure, and referring to shown in Figure 1, this back of the body bolt is made up of crab-bolt steel bushing 1, crab-bolt 2 and tightening nut 3 three members.Crab-bolt 2 is a screw rod, and crab-bolt steel bushing 1 is made of nut portions 4 and anchoring claw 5 one, and crab-bolt steel bushing 1 is connected with the outside thread of crab-bolt 2 by the internal thread of nut portions 4.During use, elder generation holes on base material and opens up the hole, according to the diameter and the buried depth size in hole, put into corresponding crab-bolt steel bushing, wherein, anchoring claw stretches in the mounting hole, the end face of nut portions abuts on the bore surfaces of base material, again crab-bolt is screwed in the crab-bolt steel bushing, and strut anchoring claw make the back of the body bolt be anchored in the vestibule, load onto L type anchor pole or the similar member that is used at last, the tightening nut of screwing on.Such project organization is simple, cost is low and easy for installation.But the greatest drawback of Cun Zaiing is not possess versatility between the back of the body bolt of same apertures in actual use, the user will prepare the crab-bolt steel bushing of respective length at the boring of different buried depth, since be subjected to the restriction of nut portions end face, can not be general between the anchoring claw of different length.The kind and the specification of back of the body bolt have just been increased so undoubtedly, give product production, manage, transport to be equipped with and bring unnecessary waste with the stock, make troubles also for user's selection, therefore, how designing a kind of back of the body bolt that has versatility between same apertures and different buried depth is the problem that the utility model need solve.
Summary of the invention
The utility model provides a kind of built-in type general back of the body bolt, its objective is the back of the body bolt versatility problem that will solve between same apertures and the different buried depth, to overcome the prior art deficiency.
For achieving the above object, the technical solution adopted in the utility model is: the general back of the body bolt of a kind of built-in type, comprise crab-bolt and claw type bolt cover, described crab-bolt has one section and is with externally threaded straight-bar, and straight-bar one end is provided with slotted eye or the bolt head that is used to screw in installation, and described claw type bolt is with one section sleeve, the sleeve inner edge is provided with internal thread and cooperates with the crab-bolt outside thread, outer rim is straight tubular, and the barrel forward end extension is provided with anchoring claw, and the rear end radially is provided with the fluted body breach that is used to install.
Related content in the technique scheme is explained as follows:
1, in the such scheme, the described slotted eye that is used to screw in installation is meant groove structure or hole structure, and wherein, the groove structure specifically refers to " one " font end slot or " ten " font end slot, and hole structure specifically refers to interior hexagonal stomidium; The described bolt head that is used to screw in installation is meant hexagonal bolt head, the first-class existing bolt header structure of four keratotic plugs.
2, in the such scheme, described " anchoring claw " is meant the disclosed pawl structure that is positioned at crab-bolt steel bushing front portion among the Chinese patent CN2711439Y, and the pawl point is provided with flange outwardly and acts on bottom outlet.The rear distraction anchoring claw is anchored in the vestibule back of the body bolt in crab-bolt is screwed into the crab-bolt steel bushing.
3, in the such scheme, can set up the nut back-up ring that a Wind-Pressure Resistance is used in that the aperture is installed when claw type bolt cover sinks to mounting hole, described nut back-up ring has a pressure-bearing end face, and axial centre is provided with internal thread and cooperates with the crab-bolt outside thread.In order to improve locating effect, to outer lug one shaft shoulder that is used to locate is set at the pressure-bearing end face middle part of nut back-up ring, the outer rim of this shaft shoulder cooperates with back of the body bolt mounting hole.
4, in the such scheme, described anchoring claw and sleeve joint outer rim are circumferentially with groove.The effect of this groove is in order to reduce anchoring claw deformation force when umbrella draws in or strut.
5, in the such scheme, the anchoring claw quantity of described claw type bolt cover front end is two～six, and every layout, wherein, best anchoring claw quantity is four to each anchoring claw at sleeve circumferencial direction homogeneous phase.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
1, the utility model is because the sleeve sections that the claw type bolt is overlapped is designed to straight tubular, and external diameter is less than the mounting hole diameter, therefore can make whole back of the body bolt general mutually between same apertures and different buried depth, overcome the defective that to prepare respective length " crab-bolt steel bushing " when existing " crab-bolt steel bushing " uses at different and then dark boring.And existing " crab-bolt steel bushing " owing to be subjected to the restriction of nut portions end face, can not be general between the anchoring claw of different length.
2, the utility model has not only been saved material because the sleeve sections that the claw type bolt is overlapped is designed to straight tubular, and processing is also convenient.
3, the utility model can significantly reduce the specification of back of the body bolt undoubtedly owing to have versatility between same apertures and different buried depth, give product production, manage, transport to be equipped with and brought convenience with the stock, bring convenience also for user's selection.
