Description

Detailed Description of the Invention (Field of Industrial Application) The present invention is directed to attaching a sash frame made of aluminum or aluminum alloy to a mounting body made of dissimilar metals such as reinforcing bars or dip bars buried in the periphery of a mounting opening in a building. This relates to an anchor for fixing a sash frame.

(Prior Art) Conventionally, in order to attach a sash frame 1 made of aluminum or an aluminum alloy to a mounting opening 2 of a building a, as shown in FIG. A method of fixing to a mounting body 3 such as a reinforcing bar or a rebar via an anchor 4 is adopted.

The mounting body 3 and anchor 4 are connected to the sash frame 1.
is made of different metals such as iron, and
Since the anchor 4 is fixed to the mounting body 3 by electric welding, if the sash frame 1 is in direct contact with the sash frame 1, contact corrosion will occur due to electrochemical action based on the potential difference between the two metals. 1 will be electrolytically eroded.

For this reason, conventionally, an insulating material 5 is coated on the sash frame attachment fitting portion 4a of the anchor 4, and the anchor 4 is
Electrical continuity was interrupted between the frame 1 and the sash frame 1.

(Problems to be Solved by the Invention) However, when fixing the anchor 4 to the mounting body 3, the anchor 4 is heated to a high temperature due to the heat generated during welding work, so the insulating material 5 In this case, it is necessary to use materials that are difficult to process and are expensive, such as ceramics with excellent heat resistance and fluorine resin (trade name: Teflon), and therefore, the anchor 4 becomes expensive. There was a problem.

Therefore, the present invention has been made in view of the above-mentioned problems, and it is possible to lower the thermal conductivity of the anchor by adding simple processing to the anchor without adding any special members or devices. To provide an inexpensive anchor by preventing high heat from welding work from being transmitted to the insulating material, and by allowing the use of an insulating material made of a resin material such as vinyl chloride, which is a relatively low heat resistant but inexpensive material. The purpose is to

(Means for Solving the Problems) For this purpose, in the present invention, the anchor is formed with a sash frame attachment fitting portion at both ends of the anchor, and an insulating material made of a resin material or the like is coated on the fitting portion. At the same time, a fixing mounting piece is formed in the center of one side edge of the anchor to be fixed to a mounting body such as a reinforcing bar or a crossbar, and a plurality of fixing pieces are formed over almost the entire area of the anchor except for the sash frame attachment fitting part. It has a structure with several holes for heat dissipation.

(Function) When the fixing mounting piece 14 of the anchor 11 is welded to a mounting body such as a reinforcing bar or a rebar, the fixing mounting piece 14 is heated to a high temperature due to the heat generated during the welding operation. High fever in piece 14 is anchor 11
The fixing mounting piece 14 is extended from the sash frame mounting fitting parts 12, 12 provided at both ends of the anchor 11 to the sash frame mounting fitting parts 12, 12 on both sides of the anchor 11. It is formed in the center of one side edge of the distant anchor, and also has a heat radiation hole 1.
5, 15, . . . are provided over almost the entire area of the anchor 11 except for the sash frame attachment fitting portions 12, 12, so that the high heat is transferred to the fixing attachment piece 14.
The heat radiation effect is efficiently performed by each heat radiation hole 12 in the process of propagating from the heat to the sash frame attachment fitting parts 12, 12, and the temperature gradually decreases as it goes to both wings of the anchor 11. The mounting fitting portions 12, 12 do not reach high temperatures.

(Example) Reference numeral 11 is an anchor for fixing the sash frame, and the anchor 11 has sash frame attachment fitting portions 1 at both ends.
2, 12 are formed, and insulating materials 13, 13 made of a resin material such as vinyl chloride, nylon, or rubber are adhered to the fitting portions 12, 12. Further, in the center of one side edge of the anchor 11 in the longitudinal direction, there is a fixing mounting piece 14 that is fixed to a mounting body such as a reinforcing bar or a rebar.
is formed by standing up almost vertically. Furthermore, the sash frame attachment fitting portion 1 of the anchor 11
Heat dissipation holes 15,
A plurality of 15, . . . are formed at appropriate intervals. In the embodiment, the heat dissipation holes 15, 15, .
Figure) shows an example of what is provided.

The heat dissipation hole 15 may be formed by punching as shown in FIG. 1, or may be formed by raising a cutout piece 16 by pressing such as drawing as shown in FIG. As shown in FIG. 2, when the cutout pieces 16 are formed in an upright manner, each cutout piece 16 functions as a heat radiation fin, so that there is an advantage that the heat radiation effect is further enhanced. Further, the shape may be round or square, and the processing method, shape, etc. can be freely selected as long as it can dissipate heat.

(Effects of the present invention) As described above, according to the present invention, a mounting piece that becomes extremely hot during welding work is formed in the center of one side edge of the anchor away from the sash frame mounting fitting part,
And the sash frame attachment fitting part 1 of the anchor 11
Heat radiation holes 15 over almost the entire area except 2 and 12,
Since a plurality of 15... are formed, when the attachment piece 14 of the anchor 11 is welded to the attachment body of reinforcing bars or differential reinforcement, the high heat generated in the attachment piece 14 is dissipated through each heat radiation hole 15 in the process of propagating through the anchor 11. Since heat is efficiently dissipated to the outside and the temperature gradually becomes low, the high heat of the mounting piece does not directly transfer to the sash frame mounting fitting part, and therefore the sash frame mounting fitting part does not become high temperature. , it is no longer necessary to use ceramics or fluorine resins (trade name: Teflon), which are difficult to process and are expensive, for the insulating material attached to the area.
Resin materials such as vinyl chloride, which have relatively low heat resistance but are inexpensive and have high insulation effects, can be used, and the heat dissipation holes can usually be formed during the manufacturing process of the anchor. Since it does not increase, it is possible to provide an inexpensive and practical anchor.
