Description

[Detailed description of the invention] [Industrial application field]

This invention relates to a support structure for a ceiling base material and its support metal fittings, and more specifically, it relates to a support structure for a ceiling base material and its support metal fittings. =
The present invention relates to a support structure for array-supporting ceiling base materials and its support metal fittings.

[Conventional technology]

As a general suspended ceiling, the ceiling base material is suspended using hanging metal fittings from the hanging bolts hanging from the ceiling slab.
A system ceiling is known in which ceiling finishing materials are arranged side by side on this ceiling base material using hanging means such as clips, and ceiling panels are successively installed between the ceiling finishing materials. In order to provide earthquake resistance, a system ceiling has been developed in which the ceiling base materials are assembled in a grid pattern on the same plane using cross-shaped connecting metal fittings (Japanese Patent Laid-Open No. 59-158856). Publication, Utility Model 60-1
(See Publication No. 30914). This type of structure has a U-shaped connector in the cross direction, and the ceiling base material is placed in each receiver, and is fixed with a fastening device such as a rivet, or an inverted U-shaped connector.
Inside each holding part of the cross-shaped connecting fitting with the letter-shaped holding part protruding in the cross direction! =It has a structure in which a ceiling base material is inserted and a covering plate is integrated so as to cover the intersection from below the connecting fitting.

[Problem to be solved by the invention]

However, in ceiling structures that support the ceiling base material using conventional cross-shaped connectors and connecting metal fittings, it is difficult to adjust the ceiling base material to a predetermined height, so it is difficult to accurately position the ceiling base grid section. There is a problem in that the ceiling panel can only be supported in a suspended state, and as a result, the installation work of the ceiling panel is time-consuming and requires skill. This invention has been made in view of the above circumstances, and includes supporting the intersections of ceiling base materials in the same plane, supporting them in a height-adjustable manner to form a ceiling base grid part, and firmly supporting the ceiling base material. The object of the present invention is to provide a support structure for a ceiling base material and its supporting metal fittings, in which the surface rigidity is improved by fixing the material. [Means for Solving the Problems] In order to achieve the above object, the support structure for ceiling base materials of the first invention includes ceiling base materials arranged in a grid to support the intersections of the ceiling base materials. The support structure is based on the assumption that the support structure is attached to a hanging bolt hanging from the ceiling slab so that the height can be adjusted. At the same time as placing the end portion, the upper surface of the placed ceiling base material is pressed by a fixing member located above the cross support member, so that the height of the ceiling base material is adjustable and on the same plane. It is supported in a shape. In the ceiling base material support structure t-S of the present invention, the receiving part of the cross support member may have any form as long as it supports the support side end of the ceiling base material, but it is preferable. It is better to form a U-shaped cross section, and a positioning protrusion is provided on the receiving surface, and a positioning notch drilled on the lower surface of the ceiling base material is fitted into this positioning protrusion. It is preferable to do so. The ceiling base material support fitting of the second invention is based on the ceiling base material support metal fittings that support the intersections of the ceiling base materials and are arranged in a grid, and the ceiling base materials are placed in a cross direction. a cross-shaped support member having a U-shaped cross-sectional receiving part; a fixing member that is temporarily fixed to a hanging bolt hanging from a ceiling slab and presses a ceiling base material from above the cross-shaped support member; The height adjusting member is screwed to the hanging bolt, and a fixing nut is screwed to the hanging bolt to fix the upper surface of the fixing member. In the supporting metal fitting of the present invention, the receiving part of the cross receiving member may have any form as long as it supports the supporting end of the ceiling base material, but preferably has a U-shaped cross section. More preferably, a positioning protrusion is formed on the receiving surface to fit into a positioning notch drilled in the lower surface of the ceiling base material. Further, the above-mentioned fixing member may be of any form, or preferably, as long as it is temporarily fixed to a hanging bolt hanging from the ceiling slab and presses the ceiling base material from above the cross support member. The fixing member has a truncated conical bowl-shaped fixing member main body that opens downward, and a reinforcing rib that is bent outward from the opening of the bowl-shaped fixing member main body. It would be better if it consists of a flange.

[Created by]

By configuring as described above, after the fixing member is temporarily fixed in advance to the hanging bolt hanging from the reference position of the ceiling slab, the height adjustment member is screwed to the hanging bolt from below the cross support member, and the cross support is assembled. After holding the member and placing the support side end of the ceiling base material on each receiver of the cross support member, adjust the horizontal position and height of the ceiling base material using the height adjustment member, and then fix it. By tightening the nut, the fixing member is pressed against the upper surface of the ceiling base material, forming a coplanar ceiling base grid portion having surface rigidity.
