JPS5851343Y2 - Anchor in aluminum or aluminum alloy sash - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an anchor for fixing an aluminum or aluminum alloy sash to an opening.

When attaching an aluminum sash to an opening in a building or general house, an anchor is attached to the aluminum sash, and the anchor is welded to the reinforcing bar of the building or to the reinforcing bar used as a binding material.A conventional anchor is shown in Figure 1. The structure is as shown in .

Reference numeral 1 designates a clamping piece cut and bent and formed, and 2 a fixing tongue piece. The anchor 3 configured in this manner is attached to the aluminum sash 4 by the clamping piece 1, and the fixing tongue piece 2 is attached.
The aluminum sash 4 is attached to the opening of a building by fixing it to a reinforcing bar 5 or the like in the opening.

Generally, an electrically conductive protective film is formed on the surface of an aluminum sash to prevent corrosion, and there is no electrical continuity between the iron anchor and the sash, preventing electrolytic corrosion. ing.

However, as mentioned above, since the clamping piece 1 of the anchor is formed by cutting a plate-shaped iron piece, there are burrs left on the cut surface, and between the clamping piece 1 and the flat part 6 there is an aluminum sash 4. When inserting the anchor, the protective film is damaged and torn by the burr, and the aluminum surface is exposed and comes into contact with the iron of the anchor 3, causing electrolytic corrosion due to the potential difference between the two metals, which will last a long time. has the disadvantage that the satsushi corrodes.

Conventionally, therefore, a cover 7 made of synthetic resin has been fitted around the clamping piece of the anchor and its surroundings, but the cover 7 has the disadvantage that it is easy to come off and requires time and effort to attach.

The present invention aims to solve the above-mentioned drawbacks and to provide an anchor that can reliably prevent electrolytic corrosion.

Figures 2, 3, and 4 show an embodiment of the present invention, in which cut-outs are provided at appropriate positions on both longitudinal sides of a plate-like piece 8 made of aluminum or the like, and the cut-outs are bent. A clamping piece 9 is formed.

An anchor 12 is formed by attaching a fixing tongue piece 10 bent at right angles to the middle of the plate-like piece 8 thus formed, with an insulating material f#11 such as rubber interposed, and fixed together with a rivet or the like. It is.

In the above structure, if necessary, it is preferable to interpose an insulator 13 on one or both sides of the rivet hole as shown in FIG.

The anchor having the above configuration is fitted to the end of the aluminum sash 4 using the clamping piece 9, and the fixing tongue piece 1 is inserted into the opening.
By attaching the ground to the fixing tongue piece 10 through the fixing tongue piece 0, since the insulators 11 and 13 are interposed between the fixing tongue piece 10 and the plate-shaped piece 8, Even if the protective film of the aluminum sash 4 is torn and the aluminum surface is exposed and comes into direct contact with the anchor 12 when the clamping piece 9 is inserted, electrolytic corrosion will not occur, increasing the durability of the sash. It has no effect on the

Incidentally, the ground to be attached to the fixing tongue may be provided to each individual anchor, or all the anchors may be connected by one ground wire.

According to the present invention having the above configuration 9 functions, even if the protective film is torn and the exposed aluminum surface comes into direct contact with the anchor when inserting the anchor into the aluminum sash as described above, the grounding point of the anchor and the aluminum Since the parts that come into contact with the sash are insulated by an insulating material, the exposed aluminum surface will not be electrolytically corroded.

Furthermore, since the plate-like piece is made of aluminum, the paris can be easily removed by soaking it in an alkaline solution, thereby eliminating adverse effects such as breaking the protective film during insertion.

Furthermore, in terms of structure, the joining of the plate-shaped piece and the fixing tongue piece can be produced in a factory, resulting in a stable product, and the workability is also excellent since no work is required at the installation site.
