Abstract
The utility model discloses a high-strength concave ceiling keel which is provided with a ribbed plate (1), an upper edge (2) and a lower edge (3), wherein both ends of the ribbed plate (1) are provided with end heads (4), a plurality of engaged points (5) are arranged on the ribbed plate (1), and lapping plates (6) which is used for lapping on the main keel are arranged on both ends of the ribbed plate (1) and the lower edge (3). The lapping plate (6) forms an L shape, one side is positioned on the inner top surface (7) of the lower edge (3), and the other side is positioned on the ribbed plate (1) among the end heads (4) and the lower edge (3). When the main keel is connected to the auxiliary keel, the L-shaped lapping plates arranged on the auxiliary keel is in lap joint with the main keel, which enhances the connecting force between the main keel and the auxiliary keel and raises the integral intensity of the keel framework. The lapping plates keep the main keel in close connection with the auxiliary keel, which keeps the splicing position lightproof and keeps a good ceiling decorative effect.
Description
Technical field:
The utility model relates to the concave type ceiling keel that a kind of indoor smallpox ceiling decoration uses, especially a kind of durable, in conjunction with tight high strength concave type ceiling keel.
Background technology:
At present, it is that main joist is pegged graft into skeleton mutually with rider keel mostly that indoor smallpox is decorated, and will be placed on the skeleton by the ceiling that fire proofing material is made again.Existing main joist and rider keel all be by a metal sheet mutually crimping system form, has the upper edge, gusset, lower edge, two row pressure chalaza are arranged on gusset, make the gusset combination that folds, the pressing point be by a pair of press bonding roller shear, pressing forms, its plane protrusion height is 1.95mm, below a row pressure chalaza be 14mm apart from the base, lower edge.There is elongated hole the main joist middle part, and the gusset of rider keel is concordant with the lower edge end face, is connected to the alloy termination of being made by galvanized steel strip with gusset, and flag sheet, flag sheet jack are all arranged on each alloy termination.During installation the alloy termination of a pair of rider keel is inserted in the elongated hole of main joist middle part, the cross section of rider keel lower edge is attached on the dual-side of main joist lower edge, flag sheet on the every pair of alloy termination, flag sheet jack are pegged graft, play the effect that is connected and fixed, main joist and rider keel are directly intersected.Existing channel exists following problem:
1. rider keel and main joist just are connected and fixed by the termination, and not only the keel overall construction intensity is low, and the engage sides imprecision of the inner top surface of secondary bone and main bone, and be gapped and cause printing opacity, influences visual appearance;
2. the biting point intensity of being processed is low, plane protrusion degree height, if the position then can influence laying of ceiling near the base of lower edge, it highly can only be risen for this reason; And the result who highly rises reduces the anti crack performance of product, so can only process two row biting points, time-consuming, effort on gusset;
3. the alloy termination of galvanized steel strip easily produces burn into and is difficult for long-term storage and uses, and intensity is low, rigidity is poor, yielding, because flag sheet elasticity is low, the perk angle is little, the essential paired two-way grafting in alloy termination, very trouble during installation; And produce galvanized steel strip also can produce harmful waste water, waste gas because of electroplating, environmental pollution is serious.
Summary of the invention:
The purpose of this utility model is low in order to solve the existing in prior technology structural strength, in conjunction with technical problems such as tight shape differences, provide a kind of durable, in conjunction with tight high strength concave type ceiling keel.
Technical solution of the present utility model is: a kind of high strength concave type ceiling keel, gusset 1, upper edge 2 and lower edge 3 are arranged, at the two ends of gusset 1 termination 4 is arranged, a plurality of biting points 5 are arranged on the gusset 1, be useful on the lapping plate 6 that is overlapped on the main joist at the two ends of gusset 1 and lower edge 3, lapping plate 6 is L-shaped, and one side is positioned on the inner top surface 7 of lower edge 3, and another side is on the gusset 1 between termination 4 and the lower edge 3.
Described biting point 5 is to form by shearing, pressing, stretching, roll milling technology, and its plane protrusion height is 1.57mm, is positioned at the 10mm place, top, base of lower edge 3.
Described termination 4 usefulness 0Cr18Ni9/SUS304 stainless steel alloy steel bands are made.
The utility model is compared with prior art has following advantage:
1. when main joist is connected with rider keel, L shaped lapping plate set on the rider keel is overlapped on the main joist, has strengthened the power that is connected between main joist and the rider keel, and the bulk strength of keel skeleton is improved; Lapping plate makes that main joist engages with rider keel closely, splicing position is light tight, the ceiling good decorating effect;
Therefore 2. plane, biting point protrusion height is little, even nearer apart from the lower edge inner top surface, also can not influence the installation of ceiling, can move down 4mm to the base, lower edge, makes two folding gussets firmly, closely fit together, and has improved the anti crack performance of product;
3. termination intensity height, corrosion-resistant, the good springiness made from 0Cr18Ni9/SUS304 stainless steel alloy steel band can increase the perk degree of flag sheet, can unidirectional grafting install, and be simple and convenient.
