）等が開発されている。The present invention relates to a ceiling structure, and more particularly to a so-called stem-type ceiling structure that facilitates the positioning of a ceiling base in a suspended ceiling and provides surface rigidity to the ceiling base. . [Prior art] As a general suspended ceiling, a charail-shaped ceiling base material is suspended using hanging metal fittings from a hanging bolt suspended from a ceiling slab, and a ceiling finishing material is attached to the ceiling base material using a hanging means such as a clip. A structure in which ceiling panels are installed in parallel and ceiling panels are successively installed between the ceiling finishing materials is known. In this case, it is necessary to connect and fix the ceiling base material with the ceiling base material positioned, and generally the connecting metal fittings and the ceiling base material are fitted together and tightened with bolts (see Utility Model Publication No. 51-12015), or the connecting metal fittings A ceiling base material is placed on top of the ceiling base material, and a cut-and-raised piece of the connecting fitting is passed through the opening provided in the ceiling base material (Jikko Sho 51-3).
5133) etc. are known. In addition, in order to provide earthquake resistance, ceiling base materials are assembled in a lattice pattern using cross-shaped connecting metal fittings (Japanese Unexamined Patent Publication No. 59-1
58856, Utility Model Application Publication No. 60-130914) and structures in which a press member is stretched in an inclined manner between an anchor for attaching a hanging bolt to a ceiling slab and a hanging bracket for suspending a ceiling base material (see Utility Model Application Publication No. (Refer to Publication No. 13749/1983) etc. have been developed.

うにした天井構造を提供しようとするものである。However, 1. Conventionally, in ceiling structures that support this type of ceiling base material, it is difficult to adjust the ceiling base material to a predetermined height position, so there is a problem that it is only possible to form the ceiling base part in an accurately positioned state. Therefore, there was a problem in that the work of installing the ceiling panel was time-consuming and required skill. In addition, it has a complicated structure to provide earthquake resistance, and it is troublesome to install it, which also poses problems such as difficulty in accurate positioning. This invention was made in view of the above circumstances, and it forms a ceiling base part of standardized dimensions by height-adjustable coplanar ceiling base rows or ceiling base cross rows, and also forms a ceiling base part with standardized dimensions. It is an object of the present invention to provide a ceiling structure in which panels and the like can be easily assembled and positioned, and earthquake resistance can be improved.

な位置決めか行える点で好ましい。In order to achieve the above object, the ceiling structure of the present invention connects and supports ceiling base materials at least in the length direction using height-adjustable support means suspended from a laminate slab to form a row of ceiling base materials. At the same time, a plurality of rows of ceiling base materials are arranged parallel to each other to form a coplanar ceiling base part, and ceiling finishing materials are installed in parallel below the ceiling base material using a hanging means that is attached to the ceiling base material. At the same time, a ceiling panel is installed between the ceiling finishing materials. In the ceiling structure of the present invention, the support means may be of any type as long as it connects and supports the ceiling base materials linearly at least in the length direction to form a row of ceiling base materials on the same plane. The ceiling base material is connected and supported in the length direction and perpendicularly to the length direction to form a ceiling base cross row, and a plurality of ceiling base cross rows are arranged parallel to each other so that they are on the same plane. It is also possible to form a ceiling base grid section. The above-mentioned support means may have any structure as long as it is suspended from the ceiling slab and is adjustable in height, but it is preferable that the support means include a receiving metal fitting on which the ceiling base material is placed and a height-adjustable structure suspended from the ceiling slab. A fixing fitting that is temporarily fixed to the hanging bolt and presses the ceiling base material from above the receiving fitting; a height adjusting part that holds the receiving fitting and is attached to the hanging bolt; Preferably, the fixing member includes a fixing nut that is screwed together and fixes the upper surface of the fixing fitting. In this case, the receiving surface of the above-mentioned receiving metal fitting on which the ceiling base material is placed may be flat, or preferably, a hole may be formed on the receiving surface of the receiving metal fitting and on the lower surface of the ceiling base material. By forming a positioning protrusion that fits into the positioning notch, the distance between the supporting means can be determined. Further, it is preferable to connect the tensioning means to the supporting end of the ceiling base material and the ceiling slab diagonally upward in the longitudinal direction of the ceiling base material, since more reliable positioning can be achieved.

架設される。By configuring as described above, with a part of the support means (fixing metal fittings) temporarily fixed in advance to the hanging bolts suspended from the reference position of the ceiling slab, the ceiling base material can be fixed at least in a straight line or perpendicularly with the support means. By supporting the ceiling base material in a shape and adjusting the height of the ceiling base material, it is possible to form a ceiling base part having a standardized uniform plane surface rigidity. In addition, by connecting the tensioning means to the supporting end of the ceiling base material and the ceiling slab diagonally upward in the longitudinal direction of this ceiling base material, the position of the ceiling base part can be accurately positioned, and the entire ceiling can be earthquake-proofed. It is possible to improve sexual performance. Then, after the ceiling finishing materials are arranged side by side at predetermined positions on the ceiling base material using a hanging means, a ceiling panel is installed between the ceiling finishing materials.
