Description

[Detailed Description of the Invention] The present invention relates to a curtain wall structure for a building, and more particularly to a structure for supporting a cross member on the outer surface of a vertical mullion fixed to a building frame.

This kind of conventional curtain wall structure consists of vertical mullions that are fixed to the building frame, and the vertical mullions are placed at intervals on the outside of the building, and the cross members are fixed directly between the mullions with bolts. It is fitted with art materials such as glass plates or opening/closing windows.

However, when constructing a curtain wall with this type of structure, a high degree of precision is required for vertical positioning and installation of the crosspieces, and since the crosspieces are completely fixed to the mullions, there is no risk of thermal expansion and contraction of the crosspieces due to outside air temperature. I was unable to respond.

The present invention was developed in consideration of the above problem, and it uses a bracket for attaching a horizontal material such as a panel or glass plate to the outside of a vertical mullion fixed to a building frame. This is a mounting structure for horizontally fixing a curtain wall horizontal material through a horizontal member, and the horizontal member mounting bracket has a substrate fixed to the mullion, and a vertical member extending from the substrate toward the outdoor side. and a vertical wing-like plate extending vertically from the outer end of the connecting plate toward both sides of the connecting plate, and the indoor side surface of the horizontal member has an opening toward the indoor direction. A concave groove is formed in which the wing-shaped plate is approximately fitted in the vertical direction, and protrusions are formed on the upper and lower walls of the concave groove, respectively, and protrude into the concave groove. A washer is provided on the outside of the room and is disposed across both upper and lower protrusions, and bolts are embedded in the washer and fitted into grooves at both ends of the wing-shaped plate. The present invention provides a structure for attaching horizontal members in a curtain wall.

Hereinafter, the present invention will be described in detail with reference to embodiments.

As shown in FIGS. 1 and 2, reference numeral 1 denotes a small beam with a shaped cross section that supports a floor slab 2 and constitutes a part of the building frame. A plurality of vertical mullions 3 are fixed in parallel to the ends of the small beams 1. A plurality of horizontal members 4 are supported vertically in parallel at predetermined intervals on the outdoor side of the mullion 3. Furthermore, a curtain wall is constructed by fitting face materials such as a glass plate 5 and an opening/closing window frame 6 between the vertically adjacent horizontal members 4, 4. In addition, 7 is a fireproof board provided on the spandrel part of the curtain wall, 8 is a ceiling board, and 9 is a mullion 3 is a fastener attached to the small beam 1.

FIG. 3 shows an embodiment in which a cross member 4 on which a side member is fitted is fixed to a mullion via a bracket for attaching the cross member. As described above, the bracket 10 for attaching the girder material is attached to the outside (outdoor side) of the mullion 3 which is vertically fixed to the building frame via fasteners. (As shown in Fig. 6, the mullion has a substantially rectangular hollow cross section, and a C-shaped channel-shaped groove 11 is formed on its outdoor side.) The bracket 10 for attaching the horizontal members is shown in Figs. 3 to 6. As shown above, the C-shaped channel groove 11
C-shaped channel-shaped groove 1 which is wider than the opening of the
1, a vertical connecting plate 22 extending from the center of the substrate at right angles to the substrate, and a connecting plate extending from the vicinity of the outer end of the connecting plate including the vertical plane. A vertical auxiliary wing-like plate 12 and a wing-like plate 23 are provided, respectively, extending parallel to the base plate on both sides of the connecting plate. The auxiliary plate and the wing-shaped plate are parallel to each other with an interval A between them, and the auxiliary plate 12 is narrower in width from side to side than the wing-shaped plate 23.

In addition, a groove 13 is formed on the indoor side surface of the horizontal member 4 and is opened toward the indoor side and is fitted vertically into both the plates 12 and 23. A protrusion 13 is formed. The width of the protrusion 13A in the indoor and outdoor directions is equal to the distance A between the two plates 12 and 23.
approximately equal to.

For installation, use horizontal material mounting bracket 10.
The board 21 is inserted into the C-shaped channel groove 11 of the mullion 3, and is attached to a predetermined position by sliding in the groove. In this example, 24 below the end of the horizontal material
The parts 25 and 25 are cut out appropriately, and the mullion 3
The above-mentioned notch 24 is inserted from above the auxiliary plate 12 and the wing strip plate 23 of the horizontal member mounting bracket 10 attached to the
and 25, and drop the horizontal material 4 into the groove 1.
3 is supported by both plates 12 and 23, and the protrusion 13A of the welding member 4 is pulled to the wing-shaped plate 23 of the weft member mounting bracket 10 using bolts via the two left and right washers 19 that span both protrusions. Tighten. For this reason, the wing plate 2
Cut grooves 23A, 23A for bolts are provided on both sides of 3 (FIG. 5).

Figure 3 shows the case where glass plate 5 is used as the surface material.
Glass plates are fitted into the face material attachment parts 14 and 15 provided on the upper and lower sides of the horizontal members 4, 4, and fixed using packing material 16 and sealing material S. In this way, when the glass plate 5 is placed on the horizontal member 4 that has been dropped into the horizontal member mounting bracket 10 from above, the weight of the glass plate is applied to the horizontal member, and no upward external force acts on the horizontal member. It will not fall off from the material mounting bracket. Furthermore, since the horizontal movement of the horizontal material is not restricted, it is possible to cope with expansion and contraction due to outside temperature, etc.

In addition, in the embodiment, the auxiliary material 12 and the wing plate 2
3 clamps the protrusion 13A of the horizontal material, stable support can be obtained both indoors and outdoors.

In addition, 17 is a rib attached to the indoor side of the glass plate, 1
7A is a batten cover. 18 indicates a vertical frame placed between the horizontal frames.

FIG. 7 shows another embodiment of the invention. In this embodiment, the auxiliary plate of the bracket 10 for attaching the weft member is omitted, and a single washer 19 is used to connect the weft member 4 and the wing plate 23. Note that the washer 19 can also be divided into two pieces, left and right, as shown in FIG.

Since the present invention is constructed as described above, it has the following advantages.

- Since the connecting plate and the wing plate have a long cross-sectional area in the vertical direction, the strength to support the weight of the face material is large.

- Positioning of the horizontal material is extremely easy due to the contact between the top surface of the wing plate and the top wall of the groove.

- Provides stable support for the weft material even when repeated positive and negative pressures are applied to the glass plate.

- Can handle thermal expansion and contraction of horizontal materials.

- The relative position of the horizontal timbers relative to the mullions in the indoor/outdoor direction can be freely changed and adjusted using horizontal timber mounting brackets with different dimensions of the connecting plates, and air conditioning components can be accommodated in the space created by this. be able to.
