Abstract
The utility model provides a telescopic piece of an anchor bolt. The telescopic piece is cylindrical, one end of which is provided with a telescopic groove and the other end of which is provided with a plurality of expansion sheets. The telescopic piece, a threaded rod, a sleeve, and a nut form an anchor bolt applied to the aperture of a stone plate; adjusting variation can be carried out freely along with a certain limitation of aperture size; the expansion sheets of the telescopic piece can expand easily in the apertures of the stone plate or a ceramic tile; thinner plates like the ceramic tile do not expand to form through holes or spalling; and the tensile strength can reach the requirement of architectural design in the plate aperture.
Description
Technical field
The utility model relates to a kind of building fixation device component, is particularly useful for the stone material plate that building curtain wall is decorated, and Ceramic Tiles connects the extensible member of equipment crab-bolt.
Background technology
Adopt the stone material plate in the existing building facade, the Ceramic Tiles curtain wall decoration is more and more, make crab-bolt formula dry-hanging method be used widely, and the crab-bolt extensible member is the stone material plate, the component of the requisite connection equipment of Ceramic Tiles.Existing expansion part is cylindrical, wherein an end has 3-4 sheet expanding plate, expanding plate and crab-bolt screw rod, sleeve pipe, nut are formed a crab-bolt during use, be installed in the hole of stone material plate, because in construction, the pore size that the stone material plate is got out does not reach consistent standard, this expansion part is under the big slightly situation of internal orifice dimension, can not be close together with the inner hole cone wall, will produce loosening, moreover this expanding plate is difficult for opening in the aperture of slabstone, does not reach required tightness and safety, thereby has brought potential safety hazard.
The utility model content
The utility model purpose provides a kind of improvement of extensible member, and this extensible member should be able to overcome the defective of above-mentioned background technology, have characteristics convenient, that be connected firmly are installed, and simple in structure easy to manufacture.
The utility model adopts technical scheme to be for achieving the above object: extensible member is the simple shape of circle, and an end of extensible member is shaped on several slots and forms several expanding plates, and an end of extensible member is shaped on a shrinkage joint, and this shrinkage joint is the top at expanding plate.
Because adopt above technical scheme: it makes extensible member of the present utility model, an end be shaped on a shrinkage joint, an end is shaped on several expanding plates.One end of described extensible member is shaped on several slots and forms several expanding plates, this slot expanding plate is easier under the effect of crab-bolt screw rod to be opened to four faces of screw rod conical surface body owing to having, described extensible member one end is shaped on a shrinkage joint, because being arranged, this shrinkage joint extensible member can do the free adjustment variation along with the sheet material pore size, (because the sheet material pore size all can not reach consistent standard in construction) extensible member cooperates with screw rod can both reach required tautness down in plate hole, and required anti-pulling intensity, thereby guaranteed the required safety of constructing, also made installation convenient more.
Description of drawings:
Fig. 1 is the main TV structure schematic diagram of extensible member in the utility model.
Fig. 2 is the plan structure schematic diagram of extensible member in the utility model.
Fig. 3 be in the utility model extensible member look up structural representation.
Specific implementation method:
As shown in Figure 1, the expanding plate 1-1 of extensible member, slot 1-2, shrinkage joint 1-3 annotate: [showing two expanding plates among the figure, can be 3 to 4 expanding plate].
The shrinkage joint 2-1 of extensible member as shown in Figure 2, same Fig. 1-3.
The expanding plate 3-1 of extensible member, slot 3-2 as shown in Figure 3.
State as can be known as shown in Figure 1: this extensible member is equipped with screw rod, sleeve pipe, crab-bolt of nut composition.Be installed in the stone material panel aperture, this extensible member can be done the free adjustment variation along with stone material panel aperture size, and the expanding plate of this extensible member is easier opening under the effect of screw rod conical surface body, reaches required anti-pulling intensity, tautness.
Claims (3)
1, a kind of extensible member of crab-bolt is characterized in that extensible member is cylindric, and extensible member one end is shaped on a shrinkage joint, and this shrinkage joint is on the top of expanding plate, and extensible member one end is shaped on several slots and forms several expanding plates.
2, the extensible member of a kind of crab-bolt as claimed in claim 1 is characterized in that an end of extensible member is shaped on a shrinkage joint, and this shrinkage joint is on the top of expanding plate.
3, the extensible member of a kind of crab-bolt as claimed in claim 1 or 2, an end that it is characterized in that extensible member is shaped on several slots and forms several expanding plates.
