Description

  The present invention relates to the technical field of a shutter device for building installed in an opening such as a doorway of a building.

Today, buildings such as buildings and condominiums have openings such as entrances and exits through which moving bodies such as people and vehicles can pass in the front-rear direction (inside and outside), and the shutter curtain can be opened and closed freely. There is a case in which an architectural shutter device configured to open and close the opening by moving to is installed. Among such architectural shutter devices, there is a case where the opening width (left-right width) of the opening is built in a wide left and right direction. In such a case, the architectural shutter device also corresponds to the width of the opening. It will be wide.
By the way, the architectural shutter device supports the left and right ends of the winding drum around which the shutter curtain is wound with the left and right support brackets. The support bracket is a vertical surface (vertical wall) provided on the housing side. One end part in the front-rear direction is attached (fixed) to the left and right support brackets, while a gap (gap) is provided between the left and right support brackets with the housing side, and the gap is moved along the movement path The shutter curtain fed out from the winding drum as a space is configured to open and close.
Such a massa part can be configured so that there is no problem in strength because it can be supported on the housing side through the support bracket at both the left and right ends, but the intermediate part in the left and right direction is relative to the housing side. Since the gap exists, it cannot receive direct support from the housing side, and as a result, it tends to be weak in strength, and this tendency is more pronounced as the frontage width is wider. In some cases, there is a possibility that the intermediate portion in the left-right direction of the musa portion hangs down due to the weight.
In such an architectural shutter device, there is a construction in which components such as a take-up drum are visually recognized from the outside. In such a device, the entire component is covered with a shutter case from the outside. The shutter case in such a case will be invisible (blindfolded), but the shutter case in this case is exposed to the outside, so durability is required and it will be strong in strength. It is common. Therefore, in the case where such a shutter case is provided, a reinforcing member suspended from the upper plate (top plate) of the shutter case is connected to the side of the massa portion, thereby reinforcing the massa portion. Have been proposed (see, for example, Patent Document 1).
However, among architectural shutter devices, many heavyweight architectural shutter devices, including the shutter curtain, are heavy, but the components including the winding drum are usually housed in the ceiling. Some components are built so that they cannot be seen directly from the outside. In such cases, the shutter case as described above is not necessarily required. Even if a case is provided, it is sufficient that the shutter case is simple enough to cover the shutter curtain wound around the winding drum, and is weak in strength. In some cases, the massa section is reinforced using a strong shutter case. The ones that can not be on the fact.
Therefore, if the shutter case is not provided in this way, or if it is provided, but it is weak in strength, the lower end portion of the U-shaped reinforcing member whose upper end portion is fixed to the housing side is used as the mass portion. What was comprised so that the said massa part may be reinforced by connecting to the side is proposed (for example, refer patent document 2).

JP 2011-12736 A JP 2013-227854 A

And by adopting the U-shaped reinforcing member supported on the housing side as in Patent Document 2, it was possible to secure the necessary strength for the massa part.

By the way, as the reinforcing member, the one corresponding to the above installation conditions is assembled in advance by welding (welding) at the factory, and this is supplied to the site. In this case, the factory responded to the site. Many reinforcing members must be manufactured and stored in stock, which not only complicates production management and inventory management at the factory, but also secures a large storage area at the factory, and further There is a problem that it is necessary to secure a large cargo space when transporting.
Also, in the unlikely event that the storage dimensions of the reinforcement members transported on site are different from those actually required, the reinforcement members are welded and fixed, so they cannot be corrected on site, and the reinforcement members are immediately put into the factory. In this case, the assembly work of the shutter device for construction is interrupted until the reinforcing member is corrected or the ordered product is delivered. Things are likely to happen.
Assuming this, it is advocated to assemble the reinforcement members on site, but there are some sites where fire is strictly prohibited and welding equipment cannot be prepared. In fact, there are cases where there is a case where equipment for taking out a proper dimension is not prepared, and it is unavoidable to assemble the factory, and there are problems to be solved by the present invention.
