Membrane ceiling support

Abstract

This article relates to a membrane ceiling support for supporting the edge of a membrane ceiling against the structural frame (walls, beams, columns, etc.) of a building. As shown in the "Reference Perspective View Showing the Names of Each Part" and the "Reference Exploded Perspective View Showing the Names of Each Part," the membrane ceiling support 10 of this article is composed of a base member 11, a height adjustment member 12, a stopper member 13, a lifting member 14, and a hanging member 15. The base member 11 has a pair of fixed portions 11a, 11a attached to the left and right sides of the flat portion of the base member 11, a pair of guide portions 11b, 11b attached to the left and right sides of the front side of the flat portion of the base member 11 in the up-down direction, a height adjustment member holding portion 11c attached to the lower front side of the flat portion of the base member 11, and an arm portion 11d protruding from the flat portion of the base member 11 to the front side with its tip facing downward. As shown in "Reference Figure 1 Showing the State of Use" and "Reference Figure 2 Showing the State of Use," the fixed portions 11a, 11a are fixed to a structural body such as a wall W using fasteners such as bolts. As shown in "Reference Perspective View Showing the Names of Each Part" and "Reference Exploded Perspective View Showing the Names of Each Part," the guide portions 11b, 11b each have a guide groove extending in the vertical direction, and guide the lifting member 14 in the vertical direction by inserting a guided piece 14a of the lifting member 14 described below. The height adjustment member holding portion 11c is a portion for holding the height adjustment member 12 described below. As shown in "Reference Figure 1 Showing the State of Use" and "Reference Figure 2 Showing the State of Use," the arm portion 11d is a portion for fixing the guide frame 50 to the tip (lower end) of its downward portion. As shown in the "Reference Perspective View Showing the Names of Each Part" and the "Reference Exploded Perspective View Showing the Names of Each Part," height adjustment member 12 is a bolt having a threaded shank and a head, and the threaded shank is inserted from below into a through-hole provided in height adjustment member holding portion 11c of base member 11 and is screwed into a threaded hole provided in lifting member 14. Furthermore, stopper member 13 is a nut that is screwed into the vicinity of the head of the threaded shank of height adjustment member 12 (bolt), thereby preventing height adjustment member 12 inserted into the through-hole of height adjustment member holding portion 11c from falling out.Furthermore, as shown in the "reference exploded perspective view showing the names of each part," the lifting member 14 has a pair of left and right guided pieces 14a, 14a, a screw hole for threading the screw shank of the height adjustment member 12 (bolt), and a through hole for attaching the hanging member 15 described below. The hanging member 15 is made up of a bolt 15a having a screw shank and a head, and a hook 15b that is threaded onto the tip end (lower end) of the screw shank of the bolt 15a, and is attached in a state hanging down from the lifting member 14 by inserting the screw shank of the bolt 15a from above into the through hole provided in the lifting member 14. As shown in "Reference Figure 1 Showing the State of Use," the membrane ceiling supports 10 of this article are fixed in a row at a predetermined interval in the approximately horizontal direction near the ceiling of the structural frame of a building (wall W in the figure), and a guide frame 50 (angle steel, etc.) is fixed and hung across the arm portion 11d of each membrane ceiling support 10. Similarly, membrane ceiling supports 10 are fixed to the structural frame of the building at locations facing these membrane ceiling supports 10 (opposing walls, etc.). The membrane ceiling 100 is constructed by suspending the membrane ceiling 100 (see "Reference Figure 2 Showing the State of Use") between the membrane ceiling support 10 fixed to the structural frame on one side (wall W, etc.) and the membrane ceiling fixed to the structural frame on the other side (opposing wall, etc.). The membrane ceiling 100 is hung around the underside of the guide frame 50, and its edge is hooked to the hook 15b of the hanging member 15. In this embodiment, a slide rail 60 is attached to the edge of the membrane ceiling 100, and a hook extending upward from the slide rail 60 is engaged with the hook 15b. When the head of the height adjustment member 12 (bolt) is manipulated from below using a tool such as a wrench or hex wrench to rotate the height adjustment member 12 (bolt) forward, the lifting member 14 threadedly engaged with the threaded shaft of the height adjustment member 12 (bolt) rises along the guide portion 11b. This allows the membrane ceiling 100 to be in a tensed state. On the other hand, when the height adjustment member 12 (bolt) is rotated in the opposite direction, the lifting member 14 descends along the guide portion 11b. This allows the membrane ceiling 100 to be in a slack state.The membrane ceiling support of this product not only makes it easier to install a membrane ceiling, but also makes it possible to easily adjust the tension of the membrane ceiling after installation.
