Detailed Description

In order to solve the technical problem of the crosstalk, the technical scheme in the embodiment of the present application has the following general idea:

because the plate body is thin, reliable connection cannot be achieved by using screws, and installation efficiency is low and position adjustment is inconvenient by using glue for connection, the applicant thinks that the plate body is fixed on the main keel by using buckle connection, and the main keel is connected with the back plate of the plate body without damaging the panel of the plate body. The buckle connection only needs the buckle firmly to make the plate body with produce reliable connection between the main joist, joint strength can not be restricted the thickness of plate body even thinner back of the body aluminum plate also can produce quick reliable connection.

In order to enable the buckle connection to have enough connection strength and convenient and quick installation, the applicant designs a connecting part specially, the connecting part comprises an expansion pipe, a pin body, a back-mounted keel and a back-mounted splicing keel, the expansion pipe is inserted into a mounting hole formed in a back plate, the pin body is positioned in the expansion pipe, a first buckle groove of the back-mounted keel or a second buckle groove of the back-mounted splicing keel is buckled on the expansion pipe, the pin body, the back-mounted keel or the back-mounted splicing keel are locked through a first screw, the bottom of the pin body is pushed against the buckle position on the expansion pipe, the back plate of the plate body is clamped between the buckle position outside the expansion pipe and the back-mounted keel or the back-mounted splicing keel, so that the plate body is connected with the back-mounted keel or the back-mounted splicing keel, and then the first plug-in piece on the back-mounted keel or the second plug-in plug on the back-mounted splicing keel is clamped into a clamping piece on the main keel, thus realizing the hoisting of the plate body.

Wherein, back of the body dress piece seam fossil fragments still have the piece that compresses tightly that is used for suppressing the plate body downwards in back of the body dress fossil fragments, can realize the connection of two adjacent plate bodies of level. The expansion pipe is designed into a double-end or multi-head structure, the expansion pipe can be prevented from rotating when the first screw is locked or unscrewed, and meanwhile, the contact area between the buckling position of the expansion pipe and the back plate is increased, so that the connection is more reliable. The cross section of the top section of the pin body is polygonal, so that the pin body can be effectively prevented from rotating when the first screw is locked, and the connection is more reliable; the cross section shape of round pin body bottom segment is circular, with the expansion pipe inner wall adaptation, and the outward flange of bottom segment side surpasss the outward flange of top segment side, and when locking first screw, the round pin body moves up, and the bottom segment is in the tendency admission pipe body and is crowded by the expansion pipe inside wall, makes the position of detaining upwards extrude the backplate of plate body to the backplate is pressed from both sides tightly between the position of detaining outside the expansion pipe and back dress dragon or back dress piece joint fossil fragments.

In addition, the suspended ceiling is convenient for constructing two-layer or multi-layer suspended ceiling layers, and the upper and lower adjacent suspended ceiling layers are connected with the main keels which are connected in series and fixed on each layer through the hanging rods. The vertical plates are arranged between the upper and lower adjacent suspended ceiling layers, so that the gap between the two suspended ceiling layers can be covered, and the suspended ceiling is more attractive integrally. The riser passes through the riser fossil fragments and back of the body dress piece seam fossil fragments and is fixed continuous with the plate body that is located the upper story, connects stably, and the installation is swift.

Secondly, gapped between the plate body and the side wall of bottom, for the wholeness of guaranteeing the furred ceiling, designed and inserted limit receipts strake and elasticity and inserted limit receipts strake dress trim cover and fix the plate body of bottom on the side wall to from the supporting plate body all around, make the plate body stably keeps the level, and plays the decorative action, inserts limit receipts strake and elasticity and inserts limit receipts strake dress trim cover buckle connection, simple to operate, swift, and connect reliably.

To sum up, the suspended ceiling for interior decoration that this application provided is totally different with current mainstream mounting structure, adopt the mode that back of the body fossil fragments or back of the body patchwork fossil fragments are fixed mutually with the backplate of plate body, through the unique structure of innovative design expansion pipe and round pin body, make back of the body fossil fragments or back patchwork fossil fragments and the thinner backplate of plate body also can produce reliable and fast and connect, and rely on the fixed mode of back of the body fossil fragments or back patchwork fossil fragments and plate body backplate, develop brand-new plate body mounting structure and mounting means, the expressive force of plate body can be fully played, very big reduction the installation degree of difficulty of plate body, and improved the installation effectiveness. Therefore, the suspended ceiling for interior decoration solves the technical problem that the connection between the plate body and the keel in the prior art cannot be reliably, quickly and position-adjustable, and has the advantages of greatly reducing the installation difficulty of the plate body, improving the installation efficiency, and being reliable in connection and position-adjustable.
