Description

[Detailed description of the invention] This invention relates to a device for installing a window unit between the mullions in a curtain wall, etc. The purpose of this invention is to easily hold the window unit between the mullions by turning the window unit, thereby increasing the stability and ease of installation. The aim is to provide a structure that brings about sexuality.

In conventional window unit mounting devices of this type, L-shaped fixing fittings are used to secure the mullion and the window unit with bolts.

However, in the case of the conventional structure mentioned above, since there is an error between the mullions, it is not possible to prepare bolt holes for mounting the fixing fittings in the mullions and the window unit in advance. The work was tedious.

Therefore, in order to improve workability on site, a screw screw was screwed onto the inner wall of the frame of the window unit, and a hook was made to protrude from the window unit to the tip of the screw, and was attached rotatably. Some are hung in grooves on the inner wall of the mullion, but in this case,
In order to insert the window unit between the mullions by turning it left and right, it is necessary to increase the groove depth of the mullion, and the position of the window unit is only regulated, which provides stability for installation. It's not a thing.

This invention was devised to solve the above-mentioned conventional problems, and its details will be explained below with reference to illustrated embodiments.

In the figure, a window unit 2 is built between mullions 1 and 1.

This window unit 2 is surrounded by a formwork 3 and a horizontal frame 4, and a rotating window 5 is provided inside thereof.

A recess 6 into which the formwork 3 fits is formed on both sides of the mullion 1, and two protruding pieces 8 are fixed to the bottom wall 7 of the recess 6 by bolts or the like in two stages corresponding to the upper and lower parts of the formwork 3. It is.

This protruding piece 8 has a hat-shaped steel cross section and has two parts at the tip of its web.
The protrusions 9, 9 of the strips are formed vertically and parallel to each other.

An opening 10 is bored in the form 3 of the window frame unit 2 in correspondence with the protrusion piece 8, and the upper part of the opening 10 has two grooves 11. in correspondence with the protrusion 9, 9. 11 is formed at the base of this groove 11, and a tapered portion 1 is formed at the base of this groove 11 to move the window unit 2 toward the indoor side and to make it easier for the protrusion 9 to fit into the groove.
2 is formed.

Further, a tongue piece 13 is formed between the grooves 1'l and l'1, and the tongue piece 13 has a long hole into which a screw 14 is inserted so that the window frame unit 2 can follow the interlayer displacement of the mullion 1. 15 is the perforation.

When installing, turn the protruding pieces 8 of the mullions 1 and 1 so that they fit into the lower part of the opening 10 of the formwork 3, erect the window unit 2 between the mullions 1 and 1, and then lower the window unit 2 into the groove 11.
．． 11 and the protrusion 9 of the protrusion piece 8 is fitted into the opening 1.
0, in particular, the screw 14 is brought into contact with the upper side of the groove 11 and the indoor side, and is inserted into the elongated hole 15 of the tongue piece 13. The screw 14 is screwed between the protrusions 9, 9 of the protrusion piece 8 and fixed.

In addition, a reinforcing plate 16 is fitted inside the formwork 3 at an appropriate position, and the tips of the screws 17 screwed into the reinforcing plate 16 and the side wall of the formwork 3 are brought into contact with the bottom wall 7 of the mullion 1 to secure the window unit 2. Position left and right.

This invention has the above-mentioned structure, and when installing a window unit in a mullion, a protruding piece protruding from the side of the mullion is inserted into an opening provided in the vertical frame of the window unit, and then hooked again. As a result, the weight of the window unit can be placed on the mullion, which improves installation retention and stability after installation.
And the work is easy.

In addition, by fitting the protrusions provided on the protrusion into the grooves provided in the opening, the attachment can be made more secure, and the opening corresponds to the two protrusions on the protrusion. Since a tapered part 12 is formed at the base of the two grooves formed on the upper part, the tapered part 12 guides the protrusion into the groove, making it easy to fit into the groove and making it easier to fit the window unit. It is also possible to draw it indoors.
