Abstract
The utility model provides a square light steel joist, which comprises a bottom surface and a side of the light steel joist, the bottom surface is provided with a longitudinal lug boss reinforcing rib, the lug bosses are distributed in parallel at both sides and the middle of a sectional material. The side is a seamless square in shape. The utility model is suitable for the light steel joist in an indoor decoration of different kinds of buildings, and has the advantages of high strength, easy construction, hard deformation and has good matching functions of use.
Description
Technical field:
The utility model relates to a kind of decorating building lightgage steel joist, the square lightgage steel joist section bar of particularly a kind of high strength.
Background technology:
In recent years, lightgage steel joist brand on the market is various, and most keel all adopt shape of a hoof section bar, in use lightgage steel joist is intersected, middle punching is fixing, but owing to adopt the shape of a hoof, thereby the then big reduction of the intensity of lightgage steel joist, long-term use can cause the lightgage steel joist distortion, and bearing capacity is poor, problems such as the fracture of plate face, distortion.
The utility model content:
The technical problems to be solved in the utility model is to make lightgage steel joist can reach high strength and not yielding, and appearance looks elegant is generous, and energy and various carrying keel and the supporting use of accessory disclose the square lightgage steel joist section bar of a kind of high strength.
The technical scheme that the utility model adopted is: square lightgage steel joist section bar, comprise keel bottom surface and side, and it is characterized in that: there is boss reinforcing rib longitudinally described bottom surface, parallel both sides and the centre that is distributed in section bar of boss.Described side is seamless square.
The beneficial effects of the utility model are: the side is seamless square, has improved the heavy burden ability to bear of bottom surface section bar, has strengthened the intensity of bottom surface section bar, adds on the bottom surface that screw is fixing can not to produce distortion, has improved the quality of engineering greatly.
Description of drawings:
Fig. 1 is the bottom surface structural representation of the square lightgage steel joist of the utility model;
Fig. 2 is a sectional view of the present utility model;
Fig. 3 is a stereogram of the present utility model;
1, boss 3, interior beading in the middle of both sides, keel bottom surface boss 2, the keel bottom surface
The specific embodiment:
With reference to the accompanying drawings 1, shown in Figure 2, boss 2 parallel distributions in the middle of both sides, the keel bottom surface boss 1 of lightgage steel joist section bar and the keel bottom surface.The lateral layout of lightgage steel joist section bar has some interior beadings 3, parallel being distributed on the lightgage steel joist, be square, the effectively fixing of screw is convenient in the setting of lightgage steel joist cross section reinforcing rib, the frictional force that the surface concavity has strengthened the keel surfaces makes screw can be difficult for sliding when hammering into, and can not make the lightgage steel joist distortion.
It is more reasonable, firmly durable that the design of square lightgage steel joist contrasts traditional shape of a hoof lightgage steel joist.
Claims (2)
1. a square lightgage steel joist section bar comprises lightgage steel joist bottom surface and side, and it is characterized in that: there is the boss of parallel distribution described bottom surface.
2. square lightgage steel joist section bar according to claim 1, it is characterized in that: the cross section of lightgage steel joist is square, and seamless.
