Description

[Detailed Description of the Invention] The present invention relates to a device for attaching a bay window to a building wall constructed using a precast concrete board such as lightweight foamed concrete (ALC).

In other words, the installation of a bay window to a building wall is generally carried out by inserting the base of the bay window main body into the window opening of the building wall and then fixing the base peripheral frame of the bay window main body to the building wall. When building with precast concrete plates such as lightweight foam concrete, this precast concrete plate has the advantage of being lightweight and has excellent heat insulation properties, but has the disadvantage of being brittle in terms of strength, so insert fittings are not used when making the precast concrete plate. It becomes necessary to embed it in one piece in advance and fix the peripheral frame of the base of the bay window main body to this insert metal fitting. Therefore, the precast concrete plate of the bay window mounting part has to be specially made, and the manufacture of the concrete plate becomes complicated. It also had the disadvantage of being disadvantageous in terms of cost.

The present invention was developed in view of these points, and an embodiment thereof will be described below based on the drawings.The building wall 2 to which the bay window main body 1 is attached as shown in FIG. 1 is a lightweight foam concrete plate 3... As shown in Fig. 2, a lightweight foamed concrete plate 3 is placed surrounding the window opening 4 of the building wall 2, and the concave portion 5 provided in the concrete plate 3 is utilized. The reinforcing bars 6 are inserted through the reinforcing bars 6, and an oval-shaped foundation metal fitting 7 is fitted to the indoor corner of the lightweight foam concrete plate 3, and one side 7a of this basic metal fitting 7 is brought into contact with the reinforcing steel 6. From this state, the base metal fittings 7 are welded to the reinforcing bars 6, and two parallel engaging grooves 9 and 10 are recessed into the base peripheral frame 8 of the bay window main body 1 on a surface parallel to the window opening 4. Either one of the engagement grooves 9 and 10 is formed.
The engaging metal fittings 11 are fitted at appropriate intervals, and support legs 12 are integrally extended from each of the engaging metal fittings 11 to the base metal fitting 7, and the supporting legs 12 and the basic metal fittings are connected to each other. 7 are welded together, and the base peripheral frame 8 of the bay window main body 1 is connected to the lightweight foamed concrete plate 3, and the base peripheral frame 8 is connected to the base peripheral frame 8 by covering the reinforcing bars 6, the engagement fittings 11, and one side 7a of the foundation metal fittings 7. Mortar 13 between lightweight foam concrete plate 3
is filled.

Reference numeral 14 indicates an interior material that covers the indoor side of the lightweight foamed concrete board 3, and 15 indicates a frame constructed between the bay window main body base peripheral frame 8 and the interior material 13.

Incidentally, the concave portion 5 of the lightweight foamed concrete board 3 is provided during the manufacture of the lightweight foamed concrete board 3 in order to connect the lightweight foamed concrete boards to construct a wall. The connection is carried out by passing reinforcing bars between the opposing recesses 5.5 of adjacent lightweight foam concrete plates and filling the recesses 5, 5 with mortar.

Therefore, the present invention attaches the foundation metal fittings 7 using the concave portion 5 originally provided in the lightweight foamed concrete plate 3 and the reinforcing bars 6 for connecting the concrete plates. There is no need to add any processing.

As detailed above, the present invention utilizes the recesses provided in the precast concrete plates and the reinforcing bars for connecting the precast concrete plates, fixes the foundation metal fittings to the reinforcing bars, and attaches the foundation metal fittings to the foundation metal fittings. Since the base surrounding frame of the bay window body is attached via the support legs, even though the precast concrete plate has the disadvantage of being weak in terms of strength, the bay window body can be strongly supported by the foundation metal fittings and reinforcing bars mentioned above. Moreover, since there is no need to embed insert metal fittings as anchor metal fittings in the precast concrete plate as in the past, the precast concrete plate used around the window opening does not have to be made to order, making manufacturing easier and reducing costs. can contribute to
