Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a blind mounting member for joining blinds to a mullion which is a frame material for a curtain wall used as an outer wall of a building or the like. About. 2. Description of the Related Art In recent years, a curtain wall has been generally used as an outer wall of a building. A curtain wall is a wall formed by assembling a window, a waist panel, and the like into a lattice-shaped frame, and is attached to a structure such as a steel frame. In principle, the curtain wall itself does not bear the weight of the structure. Therefore, an extruded material such as aluminum, which is lightweight and easy to process, is usually used for the frame material constituting the frame body. In general, an extruded material such as aluminum is manufactured by extruding a billet put in a container from the opening of a die with a ram, so that even a considerably complicated cross-sectional shape is accurately manufactured depending on the shape of the die. be able to. FIG. 3 is a schematic view showing the appearance of a curtain wall applied as an outer wall of a building, wherein 1 is glass, 2 is a cubic which is a vertical frame member of the frame, and 3 is a horizontal frame material of the frame. Is blind. In addition, the cubic 2 is also called a mullion. FIG. 4 is a partial cross-sectional view showing a part of the curtain wall shown in FIG. 3 cut in a vertical direction, and FIG. 5 is a partial cross-sectional view showing the same cut in a horizontal direction. In each case, the glass 1 is fitted on the upper and lower sides of the blind 3 seen in the center of FIG. Further, the blind 3 is joined to the mullion 2 with mounting bolts 41 and 42 via a blind mounting member (bracket) 4. [0005] The glass 1 is set on the setting block 11 placed on the upward opening of the blind 3, and after pouring a backup material 12 on the inner and outer surfaces thereof and positioning it, the sealing material 13 is filled and hardened to waterproof. It has a structure.
Further, as shown in FIG. 5, the glass 1 placed on the blind 3
Is provided with a vertical frame 22 to hold. The vertical frame 22 is formed in a groove 23 provided in the mullion 2 in the vertical direction, that is, in the vertical direction.
It is arranged by engaging the protrusion of the vertical frame 22 with a. Incidentally, the blind mounting member 4 for joining the blind 3 and the mullion 2 has conventionally been arranged as shown in FIG. FIG. 6 shows a state where the blind mounting member 4 is joined to the mullion 2, and the mullion contact side 4 a of the L-shaped blind mounting member 4 is brought into contact with the side wall of the mullion 2 and is fixed with the bolt 42. Have been. The blind 3 and the blind mounting member 4 are bolted together via a hole 41a provided on the blind contact side 4b of the blind mounting member 4. [0007] However, in such a conventional mounting, as shown in FIG.
There has been a problem that the blind mounting member 4 is inclined and joined due to a processing error a or the like. When the blind mounting member 4 is joined in a tilted manner, the blind 3 itself joined to the blind mounting member 4 is also inclined. [0008] When the tilt is generated in the eyeless manner 3 as described above, a defective assembly of the curtain wall occurs. For this reason, not only the appearance is deteriorated due to the formation of a gap on the outer surface of the building, but also problems such as a decrease in airtightness and waterproofness arise. The present invention is to improve the quality of a curtain wall by improving the joining accuracy of a blind and a mullion and enabling accurate attachment. The present inventor has proposed that a vertical groove provided in a mullion for, for example, engaging a vertical frame or the like for fixing a glass by being engaged is provided in a blind mounting position. Paying attention to the fact that it is not effectively used, the present invention has been achieved. At the blind mounting position, no vertical frame or the like is arranged because the mullion and the blind intersect. Therefore, the groove of the blind mounting surface is not used and remains as it is. The present invention utilizes the grooves which have not been used in the past, and realizes an improvement in the accuracy of seamless mounting. That is, the present invention relates to an L-shaped blind mounting member for mounting a blind on a mullion having at least one groove in a direction perpendicular to the blind mounting surface.
At least one hole portion drilled for fastening with the mullion on the mullion contact side of the letter-shaped seamless attachment member, and at least one hole drilled for fastening with the blind on the other blind contact side. The above object is achieved by a blind mounting member having one hole and a claw member extending from the blind contact side and engaging with the groove to perform vertical positioning. did. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First, a preferred embodiment of the present invention will be described with reference to FIG. In the present invention, the blind mounting member 4
It is an essential condition that a groove 23a is formed on the blind mounting surface of the mullion 2 for mounting the mullion. The shape of the groove 23a is not particularly limited. In the example of FIG. 1, as described with reference to FIG. 5, the groove for holding the vertical frame for holding the glass is used.
Positioning of the blind mounting member 4 is performed by using a claw member 43a having a shape that just engages with the groove 23a. Here, the blind attachment member 4 is L-shaped, and at least one of each of the mullion contact side 4a and the blind contact side 4b is provided.
At least one hole portion 41a, 42a is provided, and is joined and fixed to each other with bolts. As the mullion, various shapes are used. For example, in the mullion 2 shown in FIG. 2A, a vertical frame for holding glass is sandwiched between the projections of the mullion by using a jig. Fixed by that. Meanwhile, Marion 2
Is formed with a groove 23b for inserting a packing for waterproofing. In the present invention, by utilizing the groove 23b, the claw member 43b and the groove 23b are engaged with each other as shown in FIG. In the case of a mullion that does not need to provide a groove on the blind mounting surface side, at least one or more grooves are formed in advance on the blind mounting surface side of the mullion in order to apply the present invention. It is essential to keep it. As described above, in the present invention, it is essential that the mullion has at least one groove on the side of the blind mounting surface that intersects with the blind. The blind mounting member has a claw member for engaging with the groove and performing positioning. However, it is needless to say that the shape of the groove and the claw member are not limited, as long as the positioning of the attachment can be performed by engaging with each other. According to the present invention, no gap is formed in the frame material of the curtain wall, so that the appearance of the building can be improved and the airtightness and waterproofness can be improved.
