Description

[Detailed explanation of the idea] This idea is related to daylight windows.

FIG. 1 shows a conventional daylighting window A for a concrete building, and the daylighting window A is assembled using a window frame support 1 shown in FIG. That is, this metal fitting 1 has a horizontal piece 1b fixed to the upper part of the vertical piece of an L-shaped piece 1a.
The end portion of the rail is cut and raised into an L-shape, and the space between the cut and raised piece 1c and the horizontal piece 1b is used as a rail fitting slit 1d.

The construction of daylighting window A is carried out in the following steps.

(1) As shown in Figure 3, form a reinforced concrete base frame 3 with reinforcing bars 4 planted at the four corners of the upper surface.

(2) Attach the window frame support fitting 1 to the rail portions 6, 6 provided at the lower part of the inner peripheral surface of the rectangular window frame 5. That is, with the window frame support fitting 1 twisted at 45 degrees, insert its horizontal piece 1b from below between the rail parts 6, 6, and place it in the normal position (horizontal piece 1b is perpendicular to the longitudinal direction of the rail part 6). Return it and engage the rail part 6 with the rail fitting slit 1d.
The window frame support fittings 1 are attached to the four corners of the rectangular window frame 5.

(3) This rectangular window frame 5 is placed on the base frame 3 via a support (not shown).

(4) Slide the window frame support fitting 1 along the rail portion 6, align the L-shaped piece 1a with the reinforcing bar 4, and fix the L-shaped piece 1a and the reinforcing bar 4 by welding.

(5) Remove the support and fill it with mortar 7.

(6) This fixes the window frame 5. Next, place the transparent dome 9 on the horizontal piece 5a of the window frame 5 via the packing 8, and attach the bolts 1 to these.
By tightening nut 11 through 0,
The translucent dome 9 is fixed.

In this way, the reason why the window frame support fitting 1 is made to be able to slide freely along the rail part 6 is because the embedding precision of the reinforcing bars 4 is poor, so even if the reinforcing bars 4 are installed out of position, the window frame support This is to absorb the movement of the metal fittings 1 and to enable the window frame 5 to be mounted in the correct position with high precision. However, since the window frame support fitting 1 can only move in one direction (arrow B direction) along the rail portion 6, the reinforcing bar 4 can move in the other direction (arrow C direction).
There was a problem in that the window frame 5 could not be attached if the reinforcing bars 4 were out of position or the height of the reinforcing bars 4 was low.

Therefore, the purpose of this invention is to create a daylighting window that allows the window frame to be mounted accurately in the correct position even when the reinforcing bars are installed out of position in any direction in the horizontal plane or in the height direction. It is to provide.

An embodiment of this invention will be described with reference to FIGS. 4 and 5. That is, this lighting window D is
In place of the window frame support fitting 1 shown in the figure, a height adjusting screw 12, height adjusting nuts 13, 14, and a positional deviation adjusting fitting 15 are used, as shown in FIGS. 4 and 5. The window frame 5' has an L-shaped piece 16 extending in the circumferential direction of the window frame around the entire circumference of the window frame.
The height adjustment screws 12 are screwed vertically downward and penetrated into positions corresponding to the four corners of the window frame of the horizontal piece. The positional displacement adjustment fitting 15 is a substantially inverted L-shaped fitting in which a retaining piece 15b is formed by bending the lower end of a vertical piece 15a, and a long hole 17 extending in the longitudinal direction of the horizontal piece is bored in the horizontal piece 15c. 17 through the threaded rod 12a of the height adjustment screw 12. height adjustment nut 13,
14 is screwed onto the threaded rod 12a while holding the horizontal piece 15c of the displacement adjustment fitting 15. In this case, by loosening either one of the nuts 13, 14, the positional deviation adjustment fitting 15 can be freely slid in the longitudinal direction of the horizontal piece 15c along the elongated hole 15c, that is, in the direction of the arrow 15 can be freely adjusted to rotate in the direction of arrow Y around the threaded rod 12a, and by tightening the nuts 13 and 14 at the desired slide and rotation position, the horizontal piece 1
By holding 5c, position adjustment fitting 1
5 can be fixed to the threaded rod 12a. In addition, by adjusting the amount of screwing of both nuts 13 and 14 onto the threaded rod 12a, the positional deviation adjusting fitting 15 can be adjusted to the threaded rod 12a.
The height can be freely adjusted in the Z direction along arrow a. In addition, the vertical piece 1 of the positional deviation adjustment fitting 15
5a is welded to the peripheral surface of the reinforcing bar 4. Since the other configurations are the same as those of the conventional example, the same parts are given the same reference numerals and the explanation thereof will be omitted.

As a result of this configuration, even if the reinforcing bars 4 are installed in the base frame 3 with a misalignment in the height direction and horizontal direction, the misalignment adjustment fittings 15 can be inserted into the elongated holes 17.
The horizontal distance shift of the embedding position can be adjusted by sliding the embedding position in the horizontal direction along In addition, both nuts 13, 1
Since the deviation in the height direction can be adjusted by adjusting the amount of screwing of the window frame 5' into the threaded rod 12a of the window frame 5', the window frame 5' can be accurately and reliably mounted in the correct position. Moreover, the adjustment work requires both nuts 13 and 1.
4 is loosened, place the window frame 5' in the correct position above the base frame 3 via a support (not shown), and slide, rotate, and adjust the vertical piece 15a of the displacement adjustment fitting 15. This can be easily done by simply welding the reinforcing bar 4 in contact with its circumferential surface, tightening both nuts 13 and 14, and holding the horizontal piece 15c of the displacement adjusting fitting 15. Moreover, since the retaining piece 15b is embedded in the mortar 7, the pull-out strength is also increased. However, the retaining piece 15b is not necessarily necessary and may be omitted.

As described above, the lighting window of this invention consists of a concrete base frame formed into a rectangular shape with reinforcing bars planted at the four corners of the top surface, and a threaded rod protruding vertically downward from the four corners of the bottom surface, and the four corners of the bottom surface are connected to the base frame. A rectangular window frame is placed at a proper position above the base frame, facing the four corners of the upper surface of the frame, and the horizontal piece has a long hole extending in the longitudinal direction of the horizontal piece, and the threaded rod is passed through the long hole to insert the vertical piece into the reinforcing bar. an inverted L-shaped displacement adjustment fitting welded to the peripheral surface; a pair of height adjustment nuts screwed onto the threaded rod to clamp and fix the horizontal pieces of the displacement adjustment fitting; the base frame and the window frame; The structure includes mortar in which the reinforcing bars, the displacement adjusting fittings, the threaded rods, and the height adjusting nuts are embedded, and a translucent dome attached to the window frame. Even when the window frame is installed out of position in an arbitrary direction in the horizontal plane or installed out of position in the height direction, there is an effect that the window frame can be attached to the correct position with high precision.
