Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panelized metal ceiling structure applied to industrialized houses and general buildings.

[0002]

2. Description of the Related Art Wooden ceiling panels are commonly used in steel-frame industrialized houses. This type of wooden ceiling panel is often constructed by arranging wooden piers in a grid pattern at half-width grid intervals of a module size (for example, 910 mm) of a building. When the module size is 910mm, the outer dimensions are 455-910mm and the length is 1,82.
Those having a size of 0 to 3,640 mm are used. How to hang
It is said that a metal object is attached to the steel beam and the ceiling panel is fixed with nails or screws. The light iron bar ceiling material is most often used as the ceiling material for general buildings. In this case, the JIS standard material is flowed in one direction as a field edge receiving material on a bolt hung from a steel beam or an upper floor, and then the field edge material is fixed with a metal object in a direction orthogonal to the field edge receiving material. And then shed. The plasterboard etc. to be stuck on the ceiling should be fixed with screws only on the edge material.

The above-mentioned wooden ceiling panel and light iron bar material ceiling substrate each have the following drawbacks. a. Wooden ceiling panel is heavier than light steel, and large (1,820-3,
If it is about 640 mm), the construction is difficult. Since it is made of wood, it is not stable in quality, and it takes time and effort to select materials such as the presence or absence of knot holes. In order to avoid the independent pillar in the room, it is necessary to process the notch in the field, which causes noise and waste materials. b. Light iron bar material Ceiling base material is made of a single material, so it is time-consuming to construct and requires a professional. Since cutting is also performed on site, noise and waste materials are generated. Since the edge material flows in only one direction at a pitch of about 300 mm, it is not possible to screw around the outer circumference of the gypsum board at a pitch of less than 300 mm. This pitch is acceptable for general buildings, but when applied to industrialized houses, it is uneconomical to put the field materials at the specified pitch in order to satisfy the standards set by the Financial Corporation. .

Therefore, as an alternative to such a ceiling structure, the applicant of the present invention has proposed the following ceiling structure (Japanese Unexamined Patent Application Publication No. Hei 9 (1999) -96952)
-111948). This is a core in which a plurality of light iron ceiling panel frames in which a connecting material is joined are provided between a pair of parallel main frame members, and the groove portion provided in the main frame members is provided at the lower end of the ceiling hanging metal fitting. When the ceiling panel frames are attached to each other, the adjacent portions of the ceiling panel frames are hung on the building frame such as a beam with ceiling hanging metal fittings. However, with this structure, it is difficult to attach the ceiling panel frame to the ceiling suspension fitting, and the workability is not sufficiently improved.

The present invention solves the above problems and achieves weight reduction, stable quality, easy construction, shorter construction period, no professionals required, and noise and waste materials generated during construction. It is an object of the present invention to provide a panelized metal ceiling structure that facilitates the work of attaching the ceiling panel frame to the ceiling suspension fitting.

[0006]

The ceiling structure of the present invention is
The metal frame material is used as a panel to stabilize the quality, and the ceiling panel frame is held by the ceiling hanging metal fittings to improve the workability, especially the workability of attaching the panel frame to the ceiling hanging metal fitting. In addition to the above, it is assumed that noise and waste materials are prevented by eliminating screwing and nailing work and eliminating on-site processing.
The ceiling panel frame is made of metal with a joining material joined between a pair of parallel main frame materials. A plurality of the ceiling panel frames are juxtaposed side by side with the main frame member. The main frame materials of adjacent ceiling panels shall be held by a common ceiling suspension fitting, and this ceiling suspension fitting shall be installed on the building frame such as a beam. The ceiling panel may be stretched over a plurality of ceiling panel frames installed, or may be stretched in advance on individual ceiling panel frames. It said main frame member, which stands lip groove-shaped outwardly and the Z-shape as the groove depth of the upper flange side is deeper web shall be the ones bent. This web
The protrusion that protrudes inward at the top of the
The stepped portion that becomes is a dovetail groove with an inclination. Before SL Ceiling fitting, two and top overlays piece covers the upper surface of the main frame member, overlies and web of the step in the deepened web of the outer surface of the upper surface overlays piece the main frame member extends from both ends of the adjacent a bent piece shaped pair of webs engaging piece for engaging the part, two Clip portion engaging piece you interposed between the lip portion of the two main frame member projects from the top surface overlies piece It shall have a door.
Each lip engaging piece engages with the upper lip of the corresponding main material frame.
A folding part is formed to fit the main frame material to the ceiling suspension fitting.
It shall be fitted. As described above, since the web of the main frame material of the ceiling panel frame has a Z-shaped cross section, and the ceiling hanging metal fitting has the web engaging piece and the lip engaging piece having the above-mentioned configuration,
The ceiling panel can be easily attached by fitting the main frame member into this ceiling suspension fitting. Further, the ceiling hanging metal fitting can stably hold the ceiling panel. Moreover, the ceiling hanging metal fittings have a simple structure.

In this structure, the building frame may be a lower chord member of a plurality of roof trusses arranged in parallel. In this way, when the ceiling panel is attached to the lower chord member of the roof truss, the ceiling can be easily constructed even when the roof has a frame structure without ceiling beams.
