Abstract

The utility model belongs to architecture hardware piece which is employed as angle-adjustable lighter joint claw. The prior lighter joint claw comprises claw arm, upper briquette, lower briquette and bolt. The claw arm comprises a long claw arm and a plurality of short claw arms. The back of the claw arm appears H shape, and the upper briquette and lower briquette is round. A screw is arranged in the middle, wherein the heaved round portion of the edge is matched with the flute of the claw arm. The utility model provides chisel teeth separately on the flute surface of the short claw arm and long claw arm and the matched joint surface of the heaved round portion of the upper and lower briquette. The utility model can adjust, position and lock the angle of the claw arm repeatedly through the cuneate gear framework, which makes the whole point-standing curtain wall reach a reasonable appearance and forced condition. The utility model radically resolves the prior problem of 'once positioned, the product is incapable of adjustment', and realizes the artifactitious standardization of the decorating plate and lighter joint claw, therefore, the simple local installation and excellent project quality are achieved.

Description

Refuting of a kind of adjustable-angle connects pawl

Technical field

The utility model belongs to a kind of architectural hardware, relates to a kind of refuting of adjustable-angle that is used on the special-shaped point supported curtain wall and connects pawl.

Background technology

The basic mounting method of point supported curtain wall is to connect pawl by refuting of various ways to be connected between decorative board (glass, aluminium sheet etc.) and support structure (body of wall, steel work etc.), because of the position difference of each plate, require connected refuting between the pawl arm that connects pawl that corresponding suitable angle will be arranged.Have such problem this moment, some deviation of actual angle value that often requires with the job site by the point of theory value that calculates, and in factory, the pawl arm all fixes by theoretical angle value, once fixing back because soldered and can not regulate.Connect pawl and can't install at the scene so caused some to refute, also cause refuting the Geometrical Tolerance Principle that connects pawl and decorative board highly and be easy to generate stress and concentrate and the plate breakage, the point supported curtain wall of moulding complexity is like this.

For addressing this problem, existing way is that theoretical calculating combines with the actual of scene as much as possible, to reduce angular deviation.But with regard to engineering, these actual angle values only just can record in work progress, nor may come customized one by one refuting to connect pawl by actual angle.If angle can't require to regulate according to reality between the pawl arm, the problems referred to above still rationally do not solve.

Summary of the invention

The purpose of this utility model is to provide refuting of a kind of adjustable-angle to connect pawl, and it can make the requirement of pawl arm in conjunction with the scene, makes any angular adjustment and positioning and locking repeatedly.

The technical solution of the utility model is that existing refuting connect pawl and improve, refute and connect pawl and comprise pawl arm, upper holder block, lower lock block and bolt are formed, the pawl arm has 1 long claw arm and a plurality of short claw arm, the rear end of pawl arm is I shape, the right side, projection rectangle position, both sides, middle part is provided with screw, lower lock block and upper holder block are circular, the centre has screw, its edge protuberance circle part matches with the groove of pawl arm, the utility model is with the groove surface of short claw arm and long claw arm and the upper holder block that cooperates with it, on the mating face of the circle part of lower lock block edge protuberance chisel teeth is set respectively.

With combination the becoming wheeled interlock of chisel teeth of original plane.Requirement in conjunction with on-the-spot is adjusted to the pawl arm on the operating position of proper angle in the rotation between briquetting by the pawl arm, holds out against lower lock block by the hexagon socket head cap screw on each pawl arm again and locatees, and compresses lower lock block by bolt at last and comes the locking jaw arm.

The utility model is by the chisel teeth wheel mechanism, but repeated multiple times is carried out angular adjustment, location and locking to the pawl arm, make whole point supported curtain wall reach rational appearance effect and stress easily, the defective of " once the location; can't regulate " of this existing like product of just fundamentally just having determined, relatively easily realize decorative board and refuted the standardization that connects the pawl factory process, goodization of field erected simplification and workmanship.

The specific embodiment

Describe mechanism of the present utility model and embodiment in detail below in conjunction with Fig. 1-8.

This is refuted the composition that connects pawl and comprises: lower lock block 1, upper holder block 2 and be clipped in five short claw arms 3 and a long claw arm 4 between them; The lower lock block gear 5 of wedge shape, the upper holder block gear 6 of wedge shape and the pawl arm tooth 7 that is meshed with them are arranged on the bonding surface of pawl arm and last lower lock block; An end that is connected with last lower lock block at the pawl arm has and is used for the screw 8 of installing and locating screw in addition, the screw 9 that is used for installing locking jaw arm bolt 10 usefulness is arranged at the center of last lower lock block, these screw 9 aperture differences, lean on the aperture of the aperture of Lower Half less than the first half, this aperture is identical with the aperture of upper holder block 2, is adapted to interior six square bolts 10 and passes through.

Concrete enforcement is as follows: at the construction field (site), earlier the chisel teeth on five short claw arms 3 and the long claw arm 4 is stuck on the wedge shape gear of lower lock block 1, actual conditions in conjunction with the job site, the angular adjustment of each pawl arm is arrived correct position, wedge shape gear with upper holder block 2 is engaged on the chisel teeth of six pawl arm another sides then, then the hexagon socket head cap screw that cooperates is positioned at each pawl arm on the existing position by the screw 8 on each pawl arm respectively with spanner, pass through the screw 9 at briquetting center and the body of wall of back with the hexagon socket head cap screw 10 that cooperates at last, steel work or other supporter are connected, when tightening six pawl arms are pressed between the lower lock block, have so just realized the angular adjustment of each pawl arm, location and locking.

More than be that typical six pawl is refuted the example that connects pawl, in conjunction with the needs of different engineerings, two multiple combinations with the dewclaw arm can be arranged equally according to this principle.No matter pawl arm quantity how much, because the engagement of the tooth on the tooth of pawl arm concave surface and upper and lower briquetting mating face, its adjusted angle orientation is locked, and quality is guaranteed.
