Abstract

The utility model discloses the simple keel of a building structure for hanging ceilings. The cross section of the keel forms a T shape. When the simple keel is arranged, the preformed hole of the keel is used and therefore, the bottom face of the keel is connected with a same horizontal plane through a connector, and decorative boards used as the ceilings are arranged on the lower flange of the keel. The space which is occupied by the keel corresponds to the height of the T-shaped cross section after the keel is arranged, and the surface of the keel is treated through plastic spraying, so the simple keel has the advantages of small occupy occupied area, simple structure, high installation speed, high efficiency, beautiful appearance, and high durability.

Description

Simple keel

The utility model relates to a kind of member that the lifting ceiling is used in building structure, particularly simple and easy keel.

Existing ceiling, be under the built-in fitting of floor, to connect big keel mostly, hang on the clad can keel under the big keel, under the clad can keel, nail on indoor various decorative panel, the structure of this lifting ceiling, levels ply at last again, the use material is many, it is big to take the interior space, and it is loaded down with trivial details to construct, very inconvenient.

The purpose of this utility model is that a kind of simple and easy keel will be provided, and it is simple in structure, and is easy for installation, has both reduced taking indoor headroom, makes lifting ceiling work safety, rapid again, and quality is solid and reliable.

The purpose of this utility model is achieved in that the cross section of these simple and easy keel is for folding the T font that forms with cold rolling of strip steel, the surface is after plastic-blasting is handled, utilize the preformed hole on the keel, keel are assembled into the framework of geometry with plug connector, this framework bottom surface is positioned on the same horizontal plane, and the decorative panel of using as ceiling promptly is installed on the bottom flange of keel.

The utility model advantage is that this shared headroom in keel assembling back only is equivalent to the height of a T section itself, and keel itself are handled through plastic-blasting again, so it is little to take indoor headroom, simple in structure, installation rate is fast, and good looking appearance is sturdy and durable.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof:

Fig. 1 is the utility model assembling back structural representation.

Fig. 2 is main joist and a stull keel structure schematic diagram in the utility model.

Fig. 3 is the utility model assembling rear section schematic cross-sectional view.

Fig. 4 is a spreading position schematic diagram behind the keel spreading.

Fig. 5 is plug connector 5 schematic diagrames that the keel spreading is used.

Fig. 6 is a keel corner connecting portion schematic diagram.

Fig. 7 is plug connector 1 schematic diagram that keel corner uses.

Describe CONSTRUCTED SPECIFICATION of the present utility model and working condition thereof in detail below in conjunction with accompanying drawing.

With reference to accompanying drawing 1～7 this simple and easy keel cross section is the T font, form by cold rolling of strip steel is folding, handle through plastic-blasting on its surface, this formed skeleton in keel assembling back is made of keelson 4, main joist 3, stull keel 2 and plug connector, except that keelson 4 is L shaped cross section with wall is connected with nailing, main joist 3 is connected with built-in fitting in the floor with suspension rod 6, and main joist 3 and stull keel 2 cross sections are identical T font; All keel bottom surfaces all are connected on the same horizontal plane with plug connector, the gypseous decorating board of using as ceiling 7 is installed on the bottom flange of keel, wherein the plug connector used of keel spreading is that two limbs pass to turn back again behind the keel end preformed hole 8 and are attached to the lip-deep U-shaped plug connector 5 of keel, the plug connector 1 that keel corner connects usefulness is made of the mutual L shaped member connected vertically of two long limbs, the manomelia of one of them L shaped member passes to turn back behind the preformed hole 9 of stull keel 2 and is attached on the surface of stull keel, and the manomelia of another L shaped member then strides across to turn back behind the upper limb of main joist and is attached on the surface of main joist.

During use, earlier press the decorative panel geomery, install keelson and main joist, in proper order stull keel 2 are installed then and decoration pulls 7, both are interlaced proceed to all be covered with till.

Claims

Hang the member that ceiling is used in a kind of building structure, particularly simple and easy keel is characterized in that the keel cross section is the T font, form by cold rolling of strip steel is folding, and handle through plastic-blasting on its surface.
