Abstract

This invention discloses a high-intensity concave ceiling keel, comprising a reinforcement plate (1), last edge (2) and under edge (3). There are two ends (4) at the end of the reinforcement plate (1), and multiple points occlusion (5)on the reinforcement plate (1) , lap board (6) at the ends of the reinforcement plate (1) and under edge (3) used for joint with the keel, lap board (6) was L-shaped with one side located in the top surface (7) within lower side of edge (3), another side on the reinforcement plate (1) between end (4) and under edge(3). When the main keel and furring connects, the L-shaped plate set up on furring connected to the main keel, enhance their connectivity, so that enhance the strength of whole skeleton keel; the lap plate makes the main keel and furring bonding tightly, without light on the connect place, with good decorative effect of the ceiling.

Description

High strength concave type ceiling keel
Technical field:
The present invention 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 objective of the invention is in order to solve the existing in prior technology structural strength low, 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 invention 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 termination 4 usefulness 0Cr18Ni9/SUS304 stainless steel alloy steel bands are made.
The present invention compares 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.
Description of drawings:
Fig. 1 is the plugboard chart of embodiment of the invention rider keel and main joist.
Fig. 2 is the A-A view of Fig. 1.
Fig. 3 is the structural representation of embodiment of the invention biting point.
Fig. 4 is the A-A view of Fig. 3.
Fig. 5 is the B-B view of Fig. 3.
The specific embodiment:
Below in conjunction with description of drawings the specific embodiment of the present invention.
Embodiment 1:
As shown in Figure 1, 2: main joist can same prior art, rider keel is also formed by a metal sheet phase crimping system with prior art is the same, have gusset 1, upper edge 2 and lower edge 3, 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, 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.
Embodiment 2:
Other is with embodiment 1, be a plurality of biting points 5 be a row.Shown in Fig. 3,4,5: 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.
Embodiment 3:
Other is with embodiment 1 or embodiment 2, but termination 4 usefulness 0Cr18Ni9/SUS304 stainless steel alloy steel bands are made.
