Abstract
The utility model relates to a straight card light steel keel, comprising a main keel, a false keel and a suspension rod. The side face of the joint end of the main keel is provided with a raised clamping hook provided with an inclined plane from top to bottom; the other side face of the joint end of the main keel is provided with a clamping hole matched with the clamping hook; the lower end of the main keel is provided with a clamping groove used for being in clamping connection with the false keel; both sides of the middle part of the clamping groove are provided with notches; the clamping groove is in the n shape; both edges of the opening position are in curve transition; the middle part of the clamping groove is provided with bayonets toward theboth-side direction. 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 direct clamping type 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 additional spreading parts that present keel interface often adopts connect.Adopt in such a way, keel connect unstable, troublesome poeration.And regular meeting the node pine to occur spacious, spreading accuracy and do curved ability, 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 direct clamping type lightgage steel joist of node.
The utility model solves the technical scheme that its technical problem adopts.This direct clamping type lightgage steel joist comprises main joist, rider keel, suspension rod, and the tip side side of main joist is provided with the grab of projection, and this grab has inclined-plane from top to down, and the tip side side of another main joist is provided with the hole clipping that cooperates with this grab; The main joist lower end is provided with the draw-in groove that is used for the clamping rider keel, and these both sides, draw-in groove middle part have breach.This draw-in groove is n shape, and its opening part both sides arc transition has bayonet socket at the draw-in groove middle part to two side directions.
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.
Description of drawings
Fig. 1 is the structural representation of the utility model main joist one;
Fig. 2 is the structural representation of the utility model main joist two.
Description of reference numerals: 1-suspension rod fixing hole, 2-grab, 3-bayonet socket, 4-draw-in groove, 5-hole clipping, 6-main joist.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
This direct clamping type lightgage steel joist, comprise main joist 6, rider keel, suspension rod, the tip side side of main joist 6 is provided with the grab 2 of projection, and this grab 2 has inclined-plane from top to down, the tip side side of another main joist 6 is provided with the hole clipping 5 that cooperates with this grab 2, and main joist 6 cross sections are " П " shape; Main joist 6 lower ends have the draw-in groove 4 of clamping rider keel, and this draw-in groove 4 is n shape, and its opening part both sides arc transition has bayonet socket 3 at draw-in groove 4 middle parts to two side directions, and bayonet socket 3 just can block the side of rider keel.Main joist 6 tops have suspension rod fixing hole 1.When needing spreading, main joist two is socketed on the main joist one, and grab 2 blocks hole clipping 5, can guarantee that the connection of keel is stable, firm.Whole draw-in groove 4 is both artistic and practical, saves material.Adopt this mode to connect, keel connect stable, firm, efficiency of construction height, good engineering quality.
