Description

The present invention relates to building shutters and methods of assembly thereof .

Conventionally, building shutters were generally supported by a descending wall provided above an opening of a building. In this case, the left and right sides of the opening are often walls. In other words, when viewed from the front, the opening of the building frame to which the building shutter is attached has a gate-shaped mounting frame-like structure surrounded by three sides of the downward wall and the left and right walls. The shutter for building utilizes the down wall and the left and right walls as the mounting parts on the frame side to provide a horizontal winding shaft for winding the shutter curtain, a storage part for storing the shutter curtain, and a vertical movement of the shutter curtain. A pair of left and right guide rails were fixed to the building frame. In this case, various members such as the take-up shaft, storage section, and guide rail are fixed to the front of the descending wall and the left and right walls by using brackets, frame members, and the like. In other words, the various members were arranged and fixed only on the plane parallel to the plane of the shutter curtain. The surface to which the bracket that supports the winding shaft is fixed is a vertical surface that is parallel to the winding shaft.

JP-A-2000-54758

However, in recent years, the number of large-scale buildings such as distribution warehouses that do not have descending walls is increasing in order to shorten the construction period and reduce the number of materials used. In this type of building, only a plurality of pillars are erected in a large indoor space in many cases, and walls connecting the pillars are usually not constructed. In other words, the surface parallel to the winding axis is only the front surface of the column. Furthermore, in the passage-like large space, the front of the pillar was also hidden, making it impossible to attach building shutters with the conventional support structure. That is, for example, walls facing each other across a passage, facing surfaces between pillars, and the like, which are “substantially perpendicular to the horizontal winding axis and facing in the building (simply referred to as “facing surfaces in the building”). ” only exists. On the other hand, even in such buildings where there are no descending walls or left and right walls that can be used as mounting frames, there is a demand for partitioning large spaces by installing shutters between opposing walls or between pillars. be.

FIG. 11 is an explanatory view of the assembly procedure of the building shutter 11 before the shaft end support bracket 25 and the bracket fixing plate 27 are fixed.
In the building shutter 11 according to this embodiment, the plate body plate 51 of the bracket fixing plate 27 is fixed to each of the in-building facing surfaces 19 with plate fixing bolts 53 .

The plate main body plate 51 is provided with longitudinally elongated holes 105 for adjustment that allow the plate fixing bolts 53 to move in the longitudinal direction and absorb the positional deviation between the in-building facing surface 19 and the bracket fixing plate 27 . Here, in the bracket fixing plate 27 of the present embodiment, a substantially L-shaped reinforcing support member 107 is welded and fixed to the lower end of the plate main body plate 51 so as to extend, and the reinforcing support member 107 is perforated. The long hole 105 is fixed to the building facing surface 19 with a plate fixing bolt 53 .

A pair of horizontal upper and lower mounting pieces 47 protrude from each bracket fixing plate 27 fixed to the in-building facing surface 19 in a direction toward each other. A pair of upper and lower bracket fixing pieces 41 of the shaft end support bracket 25 are placed on the upper surfaces of the upper and lower mounting pieces 47, respectively. , and fixed with mounting piece fixing bolts 49 . The mounting piece 47 is provided with a left-right elongated hole 109 that allows the mounting piece fixing bolt 49 to move in the left-right direction and absorb and adjust the positional deviation between the bracket fixing plate 27 and the shaft-end support bracket 25 . .

The bracket fixing piece 41 of the shaft end support bracket 25 is fixed to the mounting piece 47 so that the bracket body plate 39 becomes parallel to the building facing surface 19 . A U-shaped support groove 37 is formed in the bracket body plate 39 . Both ends of the winding shaft 15 around which the shutter curtain 17 is wound are diametrically inserted into the support grooves 37 of the shaft end support bracket 25 fixed to the bracket fixing plate 27 . The winding shaft 15 inserted into the support groove 37 has its bearing fixed to the bracket body plate 39 with a bearing fixing bolt 43 (see FIG. 3). As a result, the winding shaft 15 is attached to the building facing surface 19 via the shaft end support bracket 25 and the bracket fixing plate 27 .

In the above-described embodiment, an example of an assembly procedure was described in which the guide rail main body 29 is first fixed to the in-building facing surface 19 and then the winding shaft 15 is supported on the in-building facing surface 19 . The guide rail main body 29 may be fixed after the winding shaft 15 is first supported.

Therefore, according to the building shutter 11 according to the present embodiment, the longitudinal elongated hole 87, the upper and lower elongated holes 89 and 91, the lateral elongated hole 93, the longitudinal elongated hole 105, the longitudinal elongated hole 87, the longitudinal elongated holes 89 and 91, the longitudinal elongated holes 93, the longitudinal elongated holes 105, the longitudinal elongated holes 89 and 91, the longitudinal elongated holes 89 and 91, the longitudinal elongated holes 93, the longitudinal elongated holes 105, the longitudinal elongated holes 89 and 91, the longitudinal elongated holes 93, the longitudinal elongated holes 93, the longitudinal elongated holes With the long holes 109, it is possible to adjust the horizontality of the winding shaft 15, the verticality of the guide rail 23, etc. by adjusting the facing surfaces 19 on the building skeleton side that are not necessarily parallel and smooth to each other, The shutter curtain 17 can be installed on the building facing surface 19 between the pillars 83 and between the walls 85. - 特許庁

Further, since the building shutter 11 can be completely fixed by fasteners such as bolts without welding, construction can be performed without fire, and construction period can be shortened.
