Abstract
The invention belongs to the field of building decoration materials, and in particular relates to a lightgage steel joist profile. The lightgage steel joist profile comprises a bottom plate and two side plates; the section of the lightgage steel joist profile is triangular and has no clearance; the section of the lightgage steel joist is in a shape of a right angled triangle; furthermore, the section of the lightgage steel joist profile is in a shape of a isosceles right triangle; a part in which the bottom plate is connected with the two side plates can be in arc transition; two triangular lightgage steel joist profiles are clung to each other through the bottom plate; the outer sections of the clung triangular lightgage steel joist profiles are rectangular or quadrate and are fastened through loops which are in match with the outer sections of the triangular lightgage steel joists in shape. According to the technical scheme, the triangular lightgage steel joist profile has the advantages that the bearing capacity of the lightgage steel joist can be effectively improved; in addition, the triangular and rectangular structure is high in stability; in addition, the triangular lightgage steel joist profile has the advantages of being simple in structure, low in processing cost and high in production efficiency.
Description
Technical field
The invention belongs to architectural decoration material field, especially relate to a kind of triangle lightgage steel joist section bar.
Background technology
At present, on market, lightgage steel joist is various in style, and the cross sectional shape of common keel has C type, U-shaped, L-type.Owing to adopting channel-section steel, the intensity of lightgage steel joist is reduced greatly, and Long-Time Service can cause lightgage steel joist to be out of shape, and rupture in plate face, bearing capacity is poor, causes potential safety hazard.
Summary of the invention
The problem to be solved in the present invention overcomes the deficiencies in the prior art, provides a kind of triangle lightgage steel joist section bar.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of triangle lightgage steel joist section bar, and comprise base plate and two side plates, the cross section of described lightgage steel joist section bar is triangular in shape, and seamless.
Further, the rectangular triangle in cross section of described lightgage steel joist section bar.
Further, the cross section of described lightgage steel joist section bar is isosceles right triangle.
Further, the part that described base plate is connected with two side plates has arc transition.
Further, every two triangle lightgage steel joist section bars are fitted mutually with base plate, outer rectangular in cross-section or square after laminating, and the banding that both outer cross section shapes and the outer cross section of lightgage steel joist match is solid.
The advantage that the present invention has and good effect are: owing to adopting technique scheme, effectively can improve the bearing capacity of lightgage steel joist, and the structural stability of triangle and rectangle is good; Also have structure simple, processing cost is low, production efficiency advantages of higher.

Detailed description of the invention
As shown in Figure 1, the invention provides a kind of triangle lightgage steel joist section bar, comprise base plate 1 and two side plates 2, the cross section of described lightgage steel joist section bar is triangular in shape, and seamless.
Shown in Fig. 2, be a kind of embodiment of the present invention, the cross section of described lightgage steel joist section bar is isosceles right triangle.
Shown in Fig. 3, be another kind of embodiment of the present invention, two described triangle lightgage steel joist section bars are fitted mutually with base plate 1, and after laminating, outer cross section is in square, and the hoop 3 that both outer cross section shapes and the outer cross section of lightgage steel joist match is fastening.
Above one embodiment of the present of invention have been described in detail, but described content being only preferred embodiment of the present invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the present patent application scope change and improve, and all should still belong within patent covering scope of the present invention.
