Description

Fastener is connected to furred ceiling fossil fragments

Technical Field

The utility model belongs to the technical field of buildings, and particularly relates to a ceiling keel connecting buckle.

Background

The use of decorative plasterboard suspended ceilings has been very widespread, with dry hanging being the dominant installation of decorative plasterboard suspended ceilings. The connection between the keels uses rivet riveting or connectionless, does not have other supports or spacing, and the stability of connection is relatively poor.

In view of this, the present utility model has been made.

Disclosure of Invention

To the problem that exists among the prior art, this patent provides a strengthen fossil fragments connection fastener of furred ceiling stability and convenient maintenance, is favorable to improving the stability of large tracts of land furred ceiling, and the maintenance of being convenient for.

In order to achieve the above purpose, the utility model provides a ceiling keel connecting fastener, which comprises a connecting plate, a buckling part and a bolt, wherein a threaded through hole matched with the bolt is formed in the connecting plate, the buckling part is symmetrically arranged at two ends of the connecting plate, and the buckling part comprises a limiting plate perpendicular to the connecting plate and a buckling protrusion arranged at the free end of the limiting plate.

Preferably, the connecting plate is welded with an inverted U-shaped reinforcing member, and a through hole for the bolt to pass through is formed in the reinforcing member.

Preferably, the surfaces of the connecting plate, the buckling part and the bolt are plated with a layer of zinc. The rust-proof step is omitted after installation, and rust-proof labor and rust-proof materials are saved, so that construction cost is saved.

The ceiling keel connecting buckle provided by the utility model has the following beneficial effects:

(1) The connecting buckle provided by the utility model enhances the stability between the keels.

(2) The utility model adopts the bolts to extrude the keels to provide the downward pressure, and the buckling bulges support the keels to provide the upward pressure to firmly link the keels, so that the keels are linked conveniently.

(3) When the keel needs to be replaced, the nut can be replaced after being loosened, the nut can be tightened after the replacement is completed, the keel can be connected again, and the replaced connecting piece can be used for multiple times.

Detailed Description

The utility model will be further described with reference to specific examples and figures to aid in the understanding of the utility model.

The ceiling construction steps generally include: measuring paying-off, fixing a suspender, installing a side keel, installing a main keel, installing a secondary keel, installing a veneer, and installing a closing strip. The suspended ceiling keel connecting buckle is mainly applied to the fixation of keels and comprises side keels, main keels and secondary keels.

As shown in fig. 1 and 2, the ceiling joist connecting fastener comprises a connecting plate 1, a reinforcing member 11, a through hole 12, a through hole 13, a fastening part 2, a limiting plate 21, a fastening protrusion 22 and a joist 4. The whole connecting plate 1 is rectangular, and the width of the connecting plate 1 shown in the left-right direction in the drawing is slightly larger than the width of the keel 4. The through hole 12 is positioned at the center of the connecting plate 1, and the inner side of the through hole is provided with threads matched with the bolt 3. The reinforcement 11 is in an inverted U shape, is fixedly connected with the upper surface of the connecting plate 1 above the through hole 12, and is provided with a through hole 13 in the center, wherein the through hole 13 is concentric with the through hole 12 in the vertical direction, and the bolt 3 can be matched with the internal thread of the through hole 12 through the through hole 13. Two buckling parts 2 are symmetrically arranged at the left end and the right end of the connecting plate 1, and the connecting plate 1 and the buckling parts 2 can be integrally formed. The buckling part 2 comprises a limiting plate 21 and buckling protrusions 22, and the limiting plate 21 is perpendicular to the connecting plate 1; the fastening protrusion 22 is horizontally disposed at a free end of the limiting plate 21 and extends toward the center of the connecting plate 1, and in this embodiment, the fastening protrusion 22 is a hook-shaped member.

As shown in fig. 3 and 4, when the keels 4 are installed, a certain gap is formed between every two keels 4, a connecting buckle with a proper width is selected according to the size of the keels 4, two ends of the butt joint of the keels 4 are inserted into the gap between the lower surface of the connecting plate 1 and the buckling protrusions 22, the circle centers of the through holes 12 and the through holes 13 are approximately aligned with the center of the gap, then the bolts 3 sequentially pass through the through holes 13 and the through holes 12, the bolts 3 are screwed downwards until the bolts are contacted with the upper surfaces of the two keels 4 at the butt joint and exert a certain pressure downwards, and at this time, the lower surfaces of the keels 4 are supported by the buckling protrusions 22, so that the keels 4 are firmly limited in the inner space of the connecting buckle. The stabilizing mode is suitable for fixing between the main joist and the main joist, between the secondary joist and between the secondary joist and the side joist.

And after the keel is installed, correcting the flatness of a lower keel, and determining that the keel is firmly installed. The standard for leveling the keels is: each keel is horizontal, the joint is not hard bent, the stress points are tightly combined, and the arching phenomenon is avoided. After leveling, the keel is rocked up and down and left and right by hands, and if the phenomenon of unstable rocking is avoided, the stability meets the standard.
