Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a device for connecting the mullions of a curtain wall to a frame.

BACKGROUND TECHNOLOGY If a mullion is made long, it will deform due to the influence of heat, so it is made to have a predetermined length and connected through a joint sleeve so as to be relatively displaceable.

For this reason, since rainwater enters the interior of the room through the joints of the mullions, the joints of the mullions are sealed, as shown in, for example, Japanese Utility Model Application Publication No. 54-38317.

Problems that the invention aims to solve With the above-mentioned seal structure, the lower and upper ends of the mullion are cut out into a complicated step-like shape, which makes it difficult to process the ends of the mullion and also makes it difficult to attach the sealing material. Because it is troublesome, the work of connecting the mullions becomes troublesome.

Means and action for solving the problem A plurality of mullion brackets are attached to the building frame via fasteners so as to have gaps in the vertical direction, and the plurality of mullions are sealed over the front surfaces of the plurality of mullion brackets. It is installed so that there is a gap in the vertical direction through the material, and the gap is vertically shifted from the gap, so that rainwater that has entered through the gap between the mullions is directed to the indoor side by the mullion bracket. Moreover, the sealing material prevents the water from entering between the mullion brackets and from entering the indoor side from the lower end of the bracket.

Embodiment FIG. 3 is a schematic front view of a curtain wall, in which mullions 1 of a predetermined length are arranged at intervals on the left and right, and are also arranged in a straight line in the vertical direction. An upper horizontal member 2 and a lower horizontal member 3 are hung horizontally between the mullions 1 to constitute a frame 4, and a panel body, for example, glass 5 is attached to each frame 4 to constitute a functional part 6. ing.

FIG. 1 is a cross-sectional view taken along the line of FIG. 3, and the structure 10 connecting the mullion 1 to the building frame 7 includes a primary fastener 11 fixed to the building frame 7, a secondary fastener 12, and a mullion bracket. 13, the lower end of the upper mullion bracket 13 and the upper end of the lower mullion bracket 13 are fixed to the secondary fastener 12, and a gap _S1 is formed between the lower end surface 13a and the upper end surface 13b. In addition, the mullion 1 constituting the functional section 6 has upper and lower mullion brackets 13, 13.
The gap S2 between the lower end surface 1a and the upper end surface _1b is vertically shifted from the gap _S1 .

The primary bracket 11 has a horizontal piece 11a and a vertical piece 1.
1b, it becomes an L-shaped long piece, and its horizontal piece 11
a is fixed to the building frame 7 with bolts 14, and a pair of secondary fasteners 12 are attached to the vertical piece 11b.
A mounting piece 12a is fixed with a bolt 15, and a plurality of vertical elongated holes 16 are formed at intervals in the vertical direction in the connecting piece 12b of the pair of secondary fasteners 12.

As shown in FIG.
c, 13c are rectangular cross-section long materials, mullion 1
has the same length as , and both side walls 1
3c and 13c are fitted between the connecting walls 12b of the pair of secondary fasteners 12, and are fastened and fixed by long bolts 17 passing through the elongated holes 16, and a sealing material 18 is interposed on the fastening surfaces. There is.

On both sides of the outdoor wall 13b of the mullioned bracket 13, hook pieces 19 are formed in the longitudinal direction to form an elongated U-shaped recess 20 that opens toward the indoor side.

The mullion 1 has a main body 21 and a presser edge 22 connected by a screw 24 via a heat-insulating connecting member 23, and the main body 21 has a substantially T-shape with a mounting wall 25 and a projecting wall 26. At the same time, a presser edge 22 is connected to the tip of the protruding wall 26 with a screw 24 via a connecting member 23, and the mounting wall 25 is attached to the concave portion 2.
It has an elongated U-shape that is almost the same as that of 0, and the sealing material 27
It is tightly fitted into the concave portion 20 via the bracket 20 and fixed to the outdoor side wall 13b of the mullioned bracket 13 with bolts 28.

Because of this, rainwater that has entered between the upper and lower mullions 1 and 1 is prevented from entering the indoor side by the outdoor surface of the mullion bracket outdoor wall 13b, or by the outdoor surface of the sealing material 27 if there is a sealing material 27. Moreover, since the sealing material 27 does not infiltrate between the mullion bracket outdoor side wall 13b and the mullion 1, the sealing material 27 does not penetrate between the upper and lower mullion brackets 13 or between the upper and lower mullion 1.
There is no need to provide a sealing material between the parts, which simplifies the structure of that part and also simplifies assembly work.

As shown in FIG. 2, the mounting wall 25 has a pair of bent pieces 31 bent into a hook shape by a protruding piece 29 and a horizontal piece 30 with the protruding wall 26 as a boundary, and a pair of locking recesses 32. One side piece 33b of the attachment 33 formed in a substantially crank shape by the intermediate piece 33a, one side piece 33b, and the other side piece 33c engages with the locking recess 32, and the intermediate piece 33a becomes a horizontal piece. 30
A pair of left and right attachments 3 are fixed to the body 21 of the mullion 1 with a screw 35 through a sealing material 34.
3 is fixed in the longitudinal direction, and a glass 5 is attached via a packing 36 between the other side piece 33c of this attachment 33 and the presser edge 22.

As shown in FIG. 1, a pair of left and right connecting plates 37 between the upper and lower mullions 1 and 1 are provided with long holes 38 and through holes 38'.
This connecting plate 37 is fixed with a screw 39 inserted through it.
As shown in FIG. 2, the protruding piece 29 and the other side piece 33c of the attachment 33 are crimped together via a sealing material 40, and the screw 39 is screwed into the other side piece 33c.

The upper and lower cross members 2 and 3 have the same shape as shown in FIG. 1, and include a main body 41 and a presser edge 42, and the main body 41 is composed of a vertical wall 43, upper and lower projecting pieces 44 and 45, and an intermediate projecting wall 46, A presser edge 42 is fixed to the tip of the intermediate projecting wall 46 with a screw 48 via a heat-insulating connecting member 47, and the presser edge 42 and the upper and lower projecting pieces 4
4 and 45, a glass 5 is attached via a gasket 49.

As shown in FIG. 4, the end of the main body 41 faces between the main body 21 of the mullion 1 and the presser edge 22, and a vertical wall 43 is fixed to the horizontal piece 30 of the main body 21 with screws 50. The end of the presser edge 42 is in contact with the end surface of the presser edge 22 of the mullion 1 via the sealing material 51, so that the outer surfaces of both presser edges 22, 42 are flush.

Since this is the case, mullion 1 is shown in Figure 5.
After the upper and lower horizontal members 2 and 3 are framed in advance, they are fitted into the recessed part 20 of the mullioned bracket 13 from the outdoor side, screwed together with screws 28 and fixed, and then the attachment 33 is attached and the glass 5 can be attached.

In addition, in FIG. 1, 52 is a U-shaped cover material, and 53 is a fireproof board.

Effects of the invention Rainwater that has entered through the gap between the upper and lower end surfaces 1b and 1a of the mullion 1 is prevented from entering the indoor side by the mullion bracket 13;
The sealing material provided between the and the mullion 1 prevents rainwater from entering between the two, and can prevent rainwater from entering the indoor side.

Furthermore, it is only necessary to connect the mullion 1 and the mullion bracket 13 so that the gaps S ₁ and S ₂ are shifted vertically, and there is no need to perform special machining of the ends of the mullion or troublesome installation work of sealing material. This simplifies the work of connecting mullions.
