Technical Field

The invention relates to a ceiling technology.

Background

Ceiling technology, especially buckle plate ceiling technology, as disclosed in patent CN201821545882X, generally comprises a triangular keel fixed on a floor slab on a roof, and buckle plates with embedded risers at four sides, wherein the triangular keel is bent into a triangle by a steel plate, a downward corner is an open corner, and two edges of the corner of the downward corner are turned outwards, of course, some technologies, as disclosed in patent CN201020281588X, are turned inwards, and the embedded riser of the buckle plate is embedded into the downward open corner, so as to fix the buckle plate. The technology is that the elastic force of the steel plate is utilized to enable the opening to have certain clamping force, the inlaid vertical plate of the pinch plate is clamped and fixed, and the clamping force formed by the elastic force is only utilized, so that no problem exists when the weight of the pinch plate is not heavy, but when the pinch plate is heavy (such as objects such as lamps and the like are installed on the pinch plate or the pinch plate made of stainless steel plate materials heavier than the pinch plate), the pinch plate is easy to fall off due to insufficient friction force formed by the clamping force.

Disclosure of Invention

The invention aims to provide a ceiling keel which can bear heavier weight, avoid the buckle plate from falling off and is easy to disassemble and assemble.

The invention is realized by the following steps that the triangular base comprises a triangular base with wing plates on two sides and an opening at the upper end, and is characterized in that the two sides of the opening at the upper end are connected with symmetrical inward-bent arc plates, the upper ends of the two arc plates are connected with vertical plates which are mutually leaned together, and the upper ends of the vertical plates are connected with outward-bent plates.

The outwardly bent plates are arc-shaped plates.

Include and insert two risers of fossil fragments for the smallpox and fix the buckle on fossil fragments for the smallpox through inlaying the riser, the riser of inlaying of buckle include the fixed riser of being connected with the buckle face, connect the arc of buckling to the inboard under the fixed riser, connect the insertion riser at the arc lower extreme of buckling to the inboard.

When in use, the buckle plate is fixed on a ceiling, then the inlaid vertical plate of the buckle plate is inserted between two vertical plates of the keel for the ceiling, because the inlaid vertical plates at the two sides of the pinch plate are respectively inserted between the two vertical plates of the keel for the ceiling at the two sides, after the buckle is inserted, the inward bent arc-shaped plate embedded with the vertical plate is positioned below the inward bent arc-shaped plate of the keel and is blocked by the inward bent arc-shaped plate, the fixed vertical plate is clamped by the two vertical plates of the keel for the ceiling, the arc-shaped plate bent inwards of the keel and the arc-shaped plate bent inwards of the buckle plate are adopted, so that the blocking force can be increased, the inlaid vertical plate of the buckle plate is not easy to loosen from the keel for the ceiling, and meanwhile, when the buckle plate needs to be taken out, under the pulling force of enough, can make the arc inclined plane of the inlaying riser of buckle relatively the arc inclined plane of the arc board of the inside bending of fossil fragments remove and break away from in the fossil fragments for the smallpox again. The utility model discloses a roof keel, including the roof keel, the roof keel is used for the roof keel, the roof keel is used for the.

Compared with the prior art, the invention has the advantages of bearing heavier weight, avoiding the pinch plate from falling off and being easy to disassemble and assemble.

Detailed Description

The present invention will now be described in further detail with reference to examples:

the invention comprises a triangular base 3 with wing plates 1 at two sides and an opening 2 at the upper end, wherein the triangular base 3 is composed of a bottom edge 3a and bevel edges 3b arranged at two ends of the bottom edge 3a, the opening 2 is formed in the space between the upper ends of the bevel edges 3b at the two ends, the lower end of the wing plate 1 which is horizontally arranged and is composed of a plate bent by 180 degrees is connected with the end part of the bottom edge 3a, the upper end of the wing plate 1 which is horizontally arranged and is composed of the plate bent by 180 degrees is connected with the lower end of the bevel edge 3b, two sides of the opening 2 at the upper end are connected with symmetrical arc plates 4 bent inwards, the upper ends of the two arc plates 4 are connected with vertical plates 5 which are mutually leaned together, and the upper end of the vertical plate 5 is connected with an arc plate 6 bent outwards. An embedded lead-in opening is formed between the two outwards bent arc plates 6. The wing plate 1, the triangular base 3, the arc plate 4, the vertical plate 5 and the arc plate 6 which is bent outwards are integrally formed by bending metal plates including stainless steel plates.

Include and insert between two risers 5 of fossil fragments for the smallpox and fix buckle a on fossil fragments for the smallpox through inlaying riser 7, buckle a's the riser 7 of inlaying includes the fixed riser 7a of being connected with buckle face 8, connects the arc 7b of buckling to the inboard under the fixed riser 7a tip, connects and inserts riser 7c at the arc 7b lower extreme of buckling to the inboard.

The length of the vertical plate 7a fixed by the buckle plate a is not less than that of the vertical plate 5, and the bending arc curvature of the arc plate 7b bent at the inner side of the embedded vertical plate 7 is not less than that of the arc plate 4 bent at the inner side. In this way, it is ensured that the inwardly bent arc 7b of the inlaid riser 7 is located below the riser 5.
