CN2692245Y - Anchor bolt used on stone material and non metal plate material and mated located sleeve - Google Patents

Abstract

The utility model discloses an anchor bolt used on stone materials and non-metal plate materials and a matched positioned sleeve, which is characterized in that: the anchor bolt which is cylindrical is provided with a groove on the front end; the groove is provided with an elastic retaining ring, the inner side or the external side of which is provided with a gap; the anchor bolt is matched with the positioned sleeve; the positioned sleeve is characterized in that: the positioned sleeve is composed of a cylinder and a pressing head handle; the inner upper part of the cylinder is cylindrical; the lower part of the cylinder is circular bench-shaped with a big top and a small bottom, and the pressing head handle is sheathed on the upper part of the cylinder. The utility model which has reasonable stress situation can be fixed with the thinner and crisper stone materials and non-metal plate materials, and furthermore, the shockproof performance of the curtain wall of the stone materials and the non-metal plate materials can be improved.

Description

Be used for crab-bolt and supporting sleeve in place on stone material and the nonmetal plate

Technical field

The utility model relates to the securing member in the building field, specifically a kind of crab-bolt and supporting sleeve in place that is used on stone material and the nonmetal plate.

Background technology

It is the shape of approximate cone that crab-bolt of the prior art or swell fixture generally adopt the top, utilize certain instrument to be pressed in stone material or the nonmetal plate then, the crab-bolt of this shape or swell fixture enter behind the sheet material because stressed not science, be easy to make the sheet material fracture, sheet material is destroyed.

Summary of the invention

The purpose of this utility model is a kind of stressed science that provides at the deficiencies in the prior art and crab-bolt and the supporting sleeve in place that can use on thin, more crisp stone material and nonmetal plate.

The purpose of this utility model is achieved in that

Be used for the crab-bolt on stone material and the nonmetal plate, characteristics are that crab-bolt is cylindrical, and its front end has groove, and groove is provided with circlip; The circlip inboard or the outside are provided with breach;

The sleeve that above-mentioned crab-bolt is in place, characteristics are that it comprises cylindrical shell and pressure head handle, and the cylindrical shell internal upper part is that cylindrical, bottom is up big and down small truncated cone-shaped, and the pressure head sleeve is contained in cylindrical shell top.

Compared with prior art, the utlity model has rational force-bearing situation, can fix thinner more crisp stone material and nonmetal plate, and then improved the shockproof properties of stone material and nonmetal plate curtain wall.

The specific embodiment

Consult Fig. 1,2,3, crab-bolt 1 of the present utility model is cylindrical, and its front end has groove 2, and groove 2 is provided with circlip 5; Circlip 5 inboards are provided with breach 6 or the outside is provided with breach 7; Sleeve of the present utility model comprises cylindrical shell 3 and pressure head handle 4, and cylindrical shell 3 internal upper parts are that cylindrical, bottom is up big and down small truncated cone-shaped, and pressure head handle 4 is sleeved on cylindrical shell 3 tops.

Consult Fig. 4,5, during use, the elastic scheibe 5 of on the groove 2 of crab-bolt 1 front end, packing into, or fasten 1 at anchor and be coated with or paste a thin elastic layer 9 with stone material 8 contact surface places, crab-bolt 1 is packed in the cylindrical shell 3, be pressed into pressure head handle 4, exert pressure to pressure head handle 4, make it withstand crab-bolt 1 and enter stone material and the nonmetal plate 8 of holding the hole in advance successfully with special tool, back in place elastic scheibe 5 opens, crab-bolt 1 connects as one with stone material and nonmetal plate, removes sleeve, carries out being pressed into of another crab-bolt again.
