Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an improvement of a deep window section (for convenience, referred to as a deep window section) in a curtain wall.

(Prior art) Conventionally, as this type of deep window section, multiple mullions are fixed to the building frame with required left and right spacing, and the width of the indoor-outdoor direction is fixed to the outdoor side of the multiple mullions. Generally used is a structure in which a plurality of wide open windows are installed at a required vertical interval, and the upper and lower ends of the glass are respectively supported by the outdoor side ends of the vertically adjacent open windows. However, this conventional deep window has a structure in which the indoor end of the wide windowless window is supported in a mullioned cantilevered state, so the drawback is that the outdoor side part of the windowless window bends downward due to the weight of the glass etc. There is. On the other hand, when the above-mentioned glass is fitted, ribbed glass is joined at right angles to the indoor surface of the fitted glass to strengthen it, but the necessary amount of support is required to support the indoor end and upper and lower ends of the ribbed glass. There was an inconvenience that a glass support member had to be prepared separately and applied to it.

(Problems to be Solved by the Invention) The object of the present invention is to achieve prevention of distortion in the glass-fitted deep window portion and support of the ribbed glass by one means.

(Means for solving the problem) In order to achieve the above purpose, the deep window section of the present project is constructed by fixing multiple mullions vertically to the building frame with the required left and right spacing, and fixing multiple mullions to the The wide open mesh is supported horizontally at the indoor end thereof with a required vertical interval, and the upper and lower ends of the glass are supported on the outdoor end of the vertically adjacent wide open mesh, and the upper and lower ends of the glass are Inside the deep window section, in which the outdoor end of the ribbed glass is joined at right angles to the glass in the vertical room, a pair of upper and lower brackets are installed, each consisting of two key-shaped arms and having glass fitting grooves on the sides of the inner corners of both arms. and fixed to the upper and lower ends of the outdoor side surface of the mullion with one arm of the bracket, respectively,
The structure is such that the other arm of the bracket supports the upper and lower blinds, and the indoor end and the upper and lower ends of the rib glass are supported in the glass fitting grooves of both the brackets. Embodiments of the present invention will be described below with reference to the drawings.

2c, ... A frame for the ranma, a frame for the window part, and a frame for the waist are respectively formed between them, and the upper and lower ends of the frame for the ranma are closed 2a,
The glass 3 is supported at the indoor end of 2b, and the glasses 4 and 5 are supported at the outdoor end of each of the upper and lower blinds 2b, 2c and 2c, 2a of the window frame and the waist frame,
As a result, a transverse part 6, a deep window part 7, and a waist part 8 are formed, and the present invention is applied to the deep window part 7.

The proposed structure of the deep window portion 7 is as follows. first,
As shown in the third figure, the mullion 1 has a holding groove 9 with a rectangular C-shaped cross section that extends toward the outdoor side on the outdoor side of its main body.
, and an open support notch 10 is formed at the open mounting position of the groove portion 9.

As shown in the second figure, the upper blind 2b forming the upper frame of the deep window has a fitting groove 11 for supporting the upper end of the glass 4 on the lower surface of the outdoor end of the wide main body, and a fitting groove 11 on the upper surface of the indoor end. They each have a fitting groove 12 that supports the lower end of the glass 3 between them, and locking grooves 13 and 14 are formed on the upper and lower surfaces of the innermost end. , has a fitting groove 15 for supporting the lower end of the glass 4 on the upper surface of the outdoor side end of the wide body, and a fitting groove 16 for supporting the upper end of the glass 5 of the waist section on the lower surface, and the indoormost end Locking grooves 17 and 18 are formed on the upper and lower surfaces of the portion.
Both the left and right ends of the indoor side ends of these upper and lower blinds 2b..., 2c... are fitted and supported in the respective notches 10, 10,... of the left and right adjacent mullions 1, 1,..., and each of the above-mentioned mullions 1 The locking plates 19, 20, each having a C-shaped cross section, are slidably inserted into the holding grooves 9 of the upper and lower pairs of the upper and lower meshes 2b, 2a and 2b of

The pair of upper and lower brackets 22, 22 that reinforce the above-mentioned support are two arms 23, 2 in the shape of a right angle key.
4, and glass fitting grooves 25, as shown in Figures 3 and 5, are provided on the sides of the inner corners of both arms 23 and 24, respectively.
26 are formed continuously, and these brackets 22, 22 are brought into contact with each corner of the mullion 1... and the upper and lower blinds 2b..., 2c... on the outdoor side of each mullion 1... , one arm 23, 23,... is fixed to the locking plate 19..., 20... with the screw 27..., and in this state, the upper and lower blinds 2b..., 2c... are screwed to the other arm 24, 24,... 28... are respectively fixedly supported.

On the other hand, the left and right adjacent glasses 4, 4, ... are joined at positions corresponding to each mullion 1, respectively, and the outdoor end of the rib glass 29 is attached to each joint with a sealing material 30 as shown in the third figure. The rib glasses 29 are joined at right angles, and each indoor end of the rib glass 29 is inserted into the fitting groove 25 of each arm 23 of the pair of upper and lower brackets 22, 22, .
. . , and filled with a sealing material 31 to maintain watertightness.

In addition, the arms 2 of the pair of upper and lower brackets 22, 22
Since the mullion-shaped holding groove part 9 is exposed between 3 and 23, the cover 32 covering this is fixed to the locking members 19 and 20 with screws 33 as shown in the fourth figure, and the cover 32 is fitted. A gap with the rib glass 29 is closed by a sealing material 35 filled in the groove 34.

In this way, the pair of upper and lower brackets 2
2 and 22 reinforce the wide upper and lower blinds 2b and 2c that are supported in a cantilevered manner, and also support the indoor end and the upper and lower ends of the ribbed glass 29.

(Effects of the invention) According to the deep window section of the curtain wall of the present invention, reinforcement of the upper and lower sides of the wide width and support of the rib glass can be achieved by a single means of a pair of brackets. The rib glass can be firmly supported to sufficiently prevent the occurrence of deflection, and the indoor end and upper and lower ends of the rib glass can be held in the fitting grooves of the bracket to ensure reliable support. It is possible.
