The invention has the following advantages:

(1) the bending strength of the C-shaped steel structure can be improved by arranging the reinforcing ribs. Further, the first circular arc line can form a first protrusion facing the second direction. The second circular arc line can further form a second protrusion facing a third direction on the first protrusion. Compared with the common reinforcing rib, the section contour line of the structure is longer, and further the bending strength is higher.

(2) The bending strength of the C-shaped steel structure can be further improved by arranging the reinforcing component.

(3) When single shaped steel structural strength is not enough, can be relative two shaped steel structures back each other, realize the butt joint extension of two C shaped steel structures through the reinforcement subassembly. The butt joint extension of C shaped steel structure is easy and simple to handle to the bending strength of two C shaped steel structures can be strengthened through same reinforcement assembly, and then can reduce use cost.

Detailed Description

The invention will be further described with reference to the accompanying drawings, without limiting the scope of the invention to the following:

as shown in fig. 1 and 2, the present application provides a C-shaped steel structure applied to roof reinforcement, which at least includes a first plate body 1, a second plate body 2 and a third plate body 3 connected end to end. The first plate 1 is disposed at a first end of the third plate 3. The second plate 2 is disposed at a second end of the third plate 3. The first plate body 1 and the second plate body 2 are substantially parallel to each other. The third plate 3 is substantially perpendicular to the first plate 1. All be provided with the strengthening rib 4 that a plurality of strip all extends along first direction on the inner wall of first plate body 1 and second plate body 2. The cross section of the reinforcing bead 4 is defined by a first circular arc line 5 curved towards a second direction and a second circular arc line 6 curved towards a third direction, wherein the second direction and the third direction are opposite to each other, and the second direction is substantially perpendicular to the first direction. The bending strength of the C-shaped steel structure can be improved by arranging the reinforcing ribs 4. Furthermore, the first circular arc line 5 can form a first projection facing the second direction. The second circular arc line 6 can further form a second protrusion facing a third direction on the first protrusion. Compared with the common reinforcing rib, the section contour line of the structure is longer, and further the bending strength is higher. As shown in fig. 1, the first direction is a direction perpendicular to the paper. The second direction may be a vertically downward direction. The third direction may be a vertically upward direction.

A reinforcing element 8 is arranged in the hollow area 7 enclosed by the first, second and

third plate bodies

1, 2, 3. One end of the reinforcing member 8 abuts against the reinforcing rib 4 attached to the first plate body 1. The other end of the reinforcement member 8 abuts against the reinforcing rib 4 attached to the second plate body 2. The bending strength of the C-shaped steel structure can be further improved by arranging the reinforcing component 8.

The reinforcement assembly 8 comprises at least several support members 8a arranged in parallel and reinforcement bars 8b extending in a first direction. The support 8a has four ends. One reinforcing rod 8b is provided on each end. In particular, the support 8a comprises at least a first body 9 and a second body 10 crosswise to each other. The two ends of the first rod and the two ends of the second rod together constitute the four ends of the support 8 a. As shown in FIG. 2, when the strength of a single section steel structure is insufficient, it is possible to realize the butt expansion of two C-section steel structures by the reinforcement assembly 8 after the two section steel structures are opposed to each other. The butt joint extension of C shaped steel structure is easy and simple to handle to the bending strength of two C shaped steel structures can be strengthened through same reinforcement component 8, and then can reduce use cost.

The working principle of this application does: when the C-shaped steel structure is used alone, the end part of the reinforcing component 8 is inserted into the reinforcing rib 4. When two C shaped steel structures need to splice and use, the end parts of the reinforcing assemblies 8 are respectively inserted into the reinforcing ribs 4 corresponding to the two adjacent C shaped steel structures.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
