Description

  The present invention relates to a curtain wall structure in which a knock-down curtain wall structure prevents an unintentional dropout during an unattended installation operation.

  Conventionally, when building the outer wall of a building by the curtain wall construction method, if you install a curtain wall unit that is pre-framed with frame materials in order, the so-called unit method, and if you install a stand on the frame at the construction site, these methods A so-called knock-down method is performed in which an opening frame is formed by attaching a space between the openings, and a curtain wall panel is attached to each opening.

  The former unit system attaches a frame-like panel unit that has been pre-assembled vertically and seamlessly, so the construction is efficient, but the connection between each unit and the water stop structure are complicated. On the other hand, the structure of the latter knock-down method is simplified, but it is necessary to carry out the work of connecting the vertical and the invisible at the work site, which takes time and labor. However, there have been problems such as labor saving and inefficiency.

  In such a knock-down method, in order to attach the blind weight in a vertical manner, as shown in FIG. 11, the weight receiving brackets 51, 51 are fixed to the vertical attachment position of the vertical 50, and then the weight receiving brackets 51, 51 are fixed. The intangible 52 is bridged between 51, and screws 53 are screwed in from the lower surface side of the self-weight receiving bracket 51 so that the invisible 52 is fixed.

In recent years, in order to save labor for unattended mounting, pins or protrusions are projected from the upper surface of the self-weight-receiving bracket, and inserted into pin holes or openings formed on the lower surface of the unweighted surface to fix the unattended. Several methods have also been proposed (see Patent Documents 1 to 4).

  However, in the case where the vertical has a T-shaped cross-section finding flange on the outdoor side surface as in the caseless mounting structure described in Patent Documents 1 to 3, there is a risk that the side drops off even if the side falls to the outdoor side. However, in the case of the structure in which the vertical does not have a locating flange or the structure in which the locating flange (vertical pressing edge) is retrofitted as in the case of the unattended mounting structure described in Patent Document 4 above, the weight is unweighted. After placing on the bracket, it was necessary to work carefully so that the eyes would not fall down and fall off until the weight receiving bracket was fixed.

  In addition, the connection between the vertical and the seamless is performed by connecting the vertical and the seamless with the self-weight-receiving bracket on the back side of the seamless using an L-shaped cross-section fixing bracket. In this case, there are many cases in which the fixing operation is performed in two ways: the first procedure using the weight receiving bracket and the second procedure using the bracket for fixing the weight, and the fastening direction of the bolts is different. There was also a problem that the nature was bad.

  Therefore, a main problem of the present invention is to provide a curtain wall structure that can hold the eyeless toppling over and fall off, and save labor for the eyeless attaching work. is there.

In order to solve the above-mentioned problem, as the present invention according to claim 1, if a vertical is attached to the housing, the weight receiving brackets are fixed to the vertical mounting positions of these verticals, and then, between the weight receiving brackets. In the curtain wall structure built by forming an opening frame over the eyes and attaching a curtain wall panel to each opening frame,
The fall prevention metal fitting is provided on the outer side of the vertical wall to prevent the fall to the invisible outdoor side, and the fall prevention metal fitting is concealed by a vertical pressing edge attached to the outdoor side of the vertical wall. A curtain wall structure is provided.

  In the first aspect of the invention, since the fall prevention metal fitting for preventing the fall to the invisible outdoor side is provided outside the vertical outdoor side, when the invisible is attached, the invisible is the outdoor side Can be reliably prevented from falling over and falling off. In addition, since the above-described anti-falling metal fitting holds down the invisible outdoor side, it is possible to eliminate the need for an invisible fixing bracket that connects the vertical and the invisible, and the installation work is labor-saving, An invisible cross-sectional shape is simplified. Furthermore, effects such as improvement in design freedom, reduction in cost, and improvement in interior design are brought about simultaneously.

  According to a second aspect of the present invention, there is provided the curtain wall structure according to the first aspect, wherein the fall prevention metal fitting has a fall prevention surface that is in contact with or close to the invisible outdoor side surface.

  In the invention according to the second aspect, since the fall-preventing metal fitting has a fall-preventing surface that comes into contact with or close to the invisible outdoor side surface, it can reliably support the eyes and prevent even a slight fall. It becomes possible.

  According to a third aspect of the present invention, there is provided the curtain wall structure according to the second aspect, wherein the fall-preventing metal fitting is attached to an end of the vertical outdoor side, and the fall-preventing surfaces are formed on both left and right sides, respectively. The

  In the invention according to the third aspect, since the fall-preventing surfaces are formed on the left and right sides, respectively, it is possible to prevent an involuntary fall on the left and right with one metal fitting.

  According to a fourth aspect of the present invention, there is provided a projection piece projecting in an invisible direction in the fall-preventing metal fitting, and a portion of an invisible number being placed on the upper surface of the projection piece. The curtain wall structure according to any one of 1 to 3 is provided.

  In the invention described in claim 4, since the fall prevention metal fitting is formed with a protruding piece protruding in the invisible direction, and an invisible part is placed on the upper surface of the protruding piece, It is possible to reliably support the eyes without any overturning operation.

  According to a fifth aspect of the present invention, the vertical pressing edge is a substantially T-shaped member having a cross-section having an locating flange and a mounting leg projecting on the interior side surface, and the mounting leg is engaged in a vertical manner. The curtain wall structure according to any one of claims 1 to 4, wherein the mounting leg portion is cut out at a portion that interferes with the fall prevention metal fitting.

  In the invention according to claim 5, the vertical pressing edge is a substantially T-shaped member having a cross-section having an locating flange and a mounting leg projecting on the interior side surface, and the mounting leg is engaged in a vertical manner. In addition, since the mounting leg portion of the portion that interferes with the fall-preventing metal fitting is cut out, the vertical pressing edge can be a continuous design in the vertical direction.

  As described in detail above, according to the present invention, in the case of an unattended attachment operation, the intangible can be held so as not to fall down and fall off, and the unattended attachment operation can be saved.
