JPS601184Y2 - 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 an 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. It is made of iron and has the structure shown in .

Reference numeral 1 designates a clamping piece cut and bent and formed, and 2 a fixing tongue piece.The anchor 3 constructed in this way is attached to the aluminum sash 4 by the clamping piece 1, and the fixing tongue piece 2
The aluminum sash 4 is attached to the opening of the 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, the clamping piece 1 of the anchor 3 is formed by cutting a piece of iron, so burrs from cutting remain on the cut surface, and the aluminum sash 4 is inserted between the clamping piece 1 and the flat part 6. When the protective film is damaged and torn by the burr, the aluminum surface is exposed and comes into direct contact with the iron of the anchor, causing electrolytic corrosion due to the potential difference between the two metals. It has the disadvantage of being corroded.

Therefore, conventionally, 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 a lot of time and effort to install.

This invention solves the above-mentioned drawbacks, and has a structure that makes it easy to insert the aluminum sash so that the base of the aluminum sash is not damaged by the burrs of the clamping pieces of the anchor. The purpose is to create an anchor that does not attach.

FIGS. 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 metal plate-like piece 8, and the cut-outs are bent. A clamping piece 9 is formed, and one or several protrusions 11 are formed in the clamping piece 9 and the flat part 10 in the longitudinal direction so that they face each other and have the same overall length. Form each one so that it protrudes.

Furthermore, a cut-out is provided at a right angle in the middle of the plate-like piece 8, or an iron piece bent at a right angle is fixed by welding, etc., to form the fixing tongue piece 1.
2 to form an anchor 13.

The anchor 13 with the above configuration is held between the clamping piece 9 and the flat part 10.
The aluminum sash 4 is attached to the opening by inserting it into the end of the aluminum sash 4 and fixing the fixing tongue piece 12 of the anchor 13 by welding to the reinforcing bar in the opening. When the anchor 13 is fitted to the sash 4, the sash is held by the protrusions 11 formed on the clamping piece 9 and the flat part 10 as shown in FIG. This will not damage the protective film on the aluminum sash surface.

Note that 14 in the drawings indicates ground.

According to the present invention having the above-described structure and operation, when inserting the end of the aluminum sash into the anchor, the protective film is not damaged by the burrs of the clamping pieces, etc., so that the bare surface of the aluminum sash is attached to the anchor. It does not come into direct contact and does not cause electrical corrosion.

Further, in terms of structure, it is only necessary to form protrusions in the longitudinal direction on both the clamping piece and the flat part, so it is easy to manufacture and does not affect the price.

Claims (1)

[Scope of utility model registration request] A clamping piece is bent on both sides in the longitudinal direction of the plate-shaped piece, and one or more protrusions are formed on the clamping piece and the flat part so that the clamping piece and the flat part face each other, and the entire length thereof is of equal height. What is claimed is: 1. An anchor for an aluminum or aluminum alloy sash, characterized in that each of the plate-shaped pieces has a protruding tongue piece protruding from the middle of the plate-like piece.
