Description

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

In conventional lighting windows installed in reinforced concrete buildings, a receiving frame is attached above a concrete base frame through a layer of mortar, and a swing window frame is attached to the receiving frame so as to be openable and closable. A gas spring is placed between the casement window frame and the receiving frame so that the casement window frame is automatically opened when the casement window frame is unlocked from the receiving frame. However,
A mounting bracket is used to connect the gas spring to the support frame, and in order to increase the mounting strength of the gas spring, the upper and lower ends of the mounting bracket are fixed to both the support frame and the mortar layer, so it cannot be opened. Each time the window frame is opened or closed, slight vibrations are transmitted to the mounting fittings via the gas spring, causing cracks in the mortar layer.

Therefore, the purpose of this invention is to provide a daylighting window that can prevent the occurrence of cracks in the mortar layer while ensuring the mounting strength of a window frame opening/closing control member such as a gas spring.

An embodiment of this invention will be described with reference to FIGS. 1 to 3. FIG. 1 is a perspective view of the lighting window A, FIG. 2 is an enlarged perspective view of the main part thereof, and FIG. 3 is a sectional view of the main part after construction. That is, as shown in FIG.
anchor bolt 2 along the circumferential direction on the top surface of
is intermittently planted, and a rectangular lower support frame 3 is placed above this base frame 1 and fixed to an anchor bolt 2 via a Z-shaped metal fitting 4. In this case, the Z-shaped fitting 4 is
The upper horizontal piece 4a is fixed to the projecting piece 3a of the lower support frame 3 with a screw 5, and the central vertical piece 4b is fixed to the anchor bolt 2 by welding.

Further, the groove-shaped crown portion 6a of the rectangular upper receiving frame 6 is externally fitted onto the inner circumferential edge convex portion 3b of the lower receiving frame 3, and connected with the bolt 8 and nut 9 via the packing 7.

As shown in FIG. 1, the horizontal frame 10a of a rectangular casement window frame 10 is pivotally connected to the horizontal frame 6b of the upper support frame 6, so that the casement window frame 10 can be freely opened above the upper support frame 6. In addition, tempered glass 11 is installed in the casement window frame 10.
is fitted, and the translucent dome 12 is placed above it.

On the other hand, L-shaped fittings 13 are protruded from the inner surfaces of both vertical frames 10b of the casement window frame 10, and both vertical frames 6c of the upper support frame 6 are provided.
Attach the mounting bracket 14 to the inner surface of the. As shown in FIG. 2 and FIG.
The lower end 14b is suspended below the upper support frame 6, and the protruding piece 14 is fixed to the outer surface of the lower end 14b.
Protrude c. Then, an elastic cap 16 made of elastic rubber or the like is fitted onto the protruding piece 14c.

Mortar is filled between the lower receiving frame 3 and the base frame 1 to form a mortar layer 17.
An upper elastic cap 16 is embedded in the inner surface of the cap. Note that this mortar layer 17 is also laminated on both sides of the base frame 1.

On the other hand, a gas spring 18 is attached between the L-shaped fitting 13 attached to the casement window frame 10 and the mounting fitting 14 attached to the upper support frame 6. This gas spring 1
8 is the shaft body 18 by the gas pressure sealed in the cylindrical body 18a.
b to protrude from the cylindrical body 18a, and the shaft body 1
While pivotally connecting one end of 8b to the L-shaped fitting 13,
The other end of the cylindrical body 18a is pivotally connected to the inner surface of the mounting fitting 14 via a bearing fitting 18c with a screw 19. Therefore, when the casement window frame 10 is unlocked from the upper support frame 6 (the locking mechanism is not shown) with the casement window frame 10 in the closed state, the shaft body 18b of the gas spring 18 protrudes from the cylindrical body 18a. , casement window frame 10
will be opened automatically.

As a result of this configuration, the upper end 14a of the mounting bracket 14 is fixed to the upper support frame 6 by the screw 15, and the projecting piece 14 of the lower end 14b of the mounting bracket 14 is fixed to the upper support frame 6 by the screw 15.
c is embedded and fixed in the mortar layer 17 via the elastic cap 16, in other words, the mounting bracket 1
4 is fixed at two places above and below, the gas spring 18 can be firmly held, and the service life of the lighting window A can be extended. In addition, since the elastic cap 16 is fitted onto the protruding piece 14c of the mounting bracket 14, the elastic cap 16 absorbs the minute vibrations transmitted to the mounting bracket 14 via the gas spring 18 when the casement window frame 10 is opened or closed. This prevents the cracks from being transmitted to the mortar layer 17, thereby preventing the occurrence of cracks in the mortar layer 17.

As described above, the daylighting window of this invention consists of a concrete base frame with anchor bolts planted on the top surface, a support frame placed above the base frame and fixed to the anchor bolts, and one horizontal frame attached to the support frame. A casement window frame is pivotally connected to a corresponding horizontal frame and can be opened upwardly from the receiving frame, and the outer surface of the upper end is fixed to the inner surface of the vertical frame of the receiving frame, and the lower end is suspended below the vertical frame. A mounting bracket having a projecting piece protruding from the outer surface of the lower end, an elastic cap fitted onto the projecting piece of the mounting bracket, and a space between the lower surface of the receiving frame and the upper surface of the base frame, and the elastic cap being placed on the inner surface. A buried mortar layer,
The window frame opening/closing control member is provided to span between the inner surface of the mounting bracket and the inner surface of the vertical frame of the casement window frame to control the opening/closing of the casement window frame, thereby ensuring the mounting strength of the window frame opening/closing control member. However, it has the effect of preventing the occurrence of cracks in the mortar layer.
