Abstract
The utility model relates to a fastening-connection light steel keel, comprising a main keel and a false keel. The main keel comprises a first main keel and a second main keel; the first main keel and the second main keel are mutually matched; the side face of the joint end of the main keel is provided with a raised lug, the side face of the joint end of the second main keel is provided with a clamping groove matched with the lug; the clamping groove is matched with the shape of the lug; the joint end of the first main keel is provided with a contraction joint. The utility model has the advantages of stable and firm connection of the keel, simple operation, improving the efficiency of construction, and meanwhile, the clamping groove has a beautiful and practical structure, saving the material.
Description
Technical field
The utility model relates to a kind of constructional materials, particularly relates to a kind of plug-in lightgage steel joist.
Background technology
The ceiling channel adopts main joist, rider keel cross to cooperate, and adds the binding suspension rod and finishes.During concrete the construction, keel often need lengthening, and the keel interface often adopts the parts of additional spreading to connect at present.Adopt in such a way, keel connect unstable, troublesome poeration.And regular meeting the node pine to occur spacious, spreading accuracy and bending resistance are poor, safety factor is low, effect is bad.
The utility model content
The utility model will solve the defective of above-mentioned prior art, provide a kind of simple to operate, connect stable, the neat plug-in lightgage steel joist of node.
The utility model solves the technical scheme that its technical problem adopts.This plug-in lightgage steel joist, comprise main joist, rider keel, main joist comprises first main joist and second main joist that cooperatively interacts, the tip side side of first main joist is provided with the projection of projection, the tip side side of second main joist is provided with the draw-in groove that cooperates with this projection, and the shape of this draw-in groove and projection is complementary; Have shrinkage joint on the first main joist tip side.
The effect that the utility model is useful is: keel connect stable, firm; Simple to operate, improved efficiency of construction; The draw-in groove structure is both artistic and practical, saves material.

Fig. 1 is the structural representation of the utility model first main joist;
Fig. 2 is the structural representation of the utility model second main joist;
Fig. 3 is the structural representation that the utility model first main joist is connected with second main joist;
Fig. 4 is the utility model user mode structural representation.
Description of reference numerals: 1-the first main joist, 2-bayonet socket, 3-breach, 4-projection, 5-shrinkage joint, 6-draw-in groove, 7-the second main joist, 8-rider keel, 9-suspension rod.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described further:
This plug-in lightgage steel joist, comprise main joist, rider keel 8, main joist comprises first main joist 1 and second main joist 7 that cooperatively interacts, the tip side side of first main joist 1 is provided with the projection 4 of projection, one end of projection 4 is connected with the side smooth transition, makes the cross section of projection 4 be similar to triangle.The tip side side of second main joist is provided with the draw-in groove 6 that cooperates with this projection 4, and this draw-in groove 6 is complementary with the shape of projection 4; Have shrinkage joint 5 on first main joist, 1 tip side.The main joist cross section is " ∏ " shape; The main joist lower end has the bayonet socket 2 of clamping rider keel, and these both sides, bayonet socket 2 middle part have breach 3.Breach 3 just can block the card rail of rider keel.Breach 3 has downward recess, and the card rail has the card article of downward folding, and card article is with after recess cooperates like this, and breach 3 is connected closelyr with rider keel.Whole draw-in groove is both artistic and practical, saves material.The main joist top has the suspension rod fixing hole, is fixed on the ceiling by suspension rod 9.When needing spreading, second main joist 7 is socketed on first main joist 1, and projection 4 is stuck in the draw-in groove 6, can guarantee that the connection of keel is stable, firm.In the cover termination process, the tip side of first main joist 1 adds the elasticity of steel owing to have shrinkage joint 5, and tip side can inwardly shrink, and is convenient to second main joist 7 and is placed on the tip side of first main joist 1.Adopt this mode to connect, keel connect stable, firm, efficiency of construction height, good engineering quality.
