Description

a building profile

technical field

The invention relates to the technical field of keel profiles used in buildings, in particular to a building profile.

Background technique

At present, the light steel keel used in the building is formed by extruding a mold after slitting the galvanized sheet. The width of the profile is determined by the width of the strips after slitting. By cutting strips of different widths, building profiles of different widths can be obtained. The building profiles can be used in decoration, such as the laying of some indoor wall panels, etc. The profile can be used, and in order to facilitate the assembly of the profile and reduce the cost of the material formed, generally several through holes are opened on the profile to facilitate the insertion of other profiles to form a skeleton structure. The opening of the hole is generally formed by punching on the profile. However, the profiles currently on the market require more metal raw materials.

Contents of the invention

The technical problem to be solved by the present invention is to provide a building profile, which saves raw materials compared with profiles of the same specification on the market.

In order to solve the above technical problems, the technical solution of the present invention is: a building profile, including a profile body made of metal material, the profile body includes a middle plate, and the edges on both sides of the middle plate are bent to form longitudinal folds. On the side, at least two rows of through holes extending longitudinally are arranged on the middle plate part, and the through holes in adjacent rows are arranged in offsets, wherein each through hole shares a connection with the adjacent through holes in the offset position. The connecting portion includes at least two twisted connecting ribs formed by transverse stretching, and gaps are provided between the twisted connecting ribs.

As a preferred solution, several reinforcing ribs are further provided on the middle plate, and each reinforcing rib is respectively located between each row of adjacent through holes.

As a preferred solution, the reinforcing rib is a transversely extending reinforcing rib.

As a preferred solution, the reinforcing ribs are located on the symmetry line of another row of corresponding through holes.

As a preferred solution, longitudinal ribs are respectively provided on the outer sides of the through holes on the middle plate portion, and the longitudinal ribs are connected with corresponding reinforcing ribs.

As a preferred solution, the free end of the reinforcing rib is set as a spherical end.

As a preferred solution, the through hole is a polygonal hole, wherein the through hole includes three connected straight hole sides on the middle plate, the angle between the three straight hole sides is 120°, each straight hole The vertices where the edges connect are rounded.

As a preferred solution, the longitudinal fold is further provided with a reinforcing fold, and the reinforcing fold is parallel to the plate surface of the middle plate portion.

As a preferred solution, the hole sides on the left and right sides of the through hole include a section of hole side extending transversely.

After adopting the above-mentioned technical solution, the effect of the present invention is: since the building profile includes a profile body made of metal, the profile body includes a middle plate, and the edges on both sides of the middle plate are bent to form a longitudinal Folding, at least two rows of longitudinally extending through-holes are arranged on the middle plate, and the through-holes of adjacent rows are misplaced, wherein each through-hole shares a The connecting part, the connecting part includes at least two twisted connecting ribs formed by transverse stretching, gaps are arranged between each twisted connecting rib, and the common connecting parts of the building profiles are twisted by stretching due to the common connecting parts of the through holes. Connecting ribs, therefore, you can use a relatively narrow strip plate and then form it into a conventional profile, then stamp it to form the hole mark of the through hole, and then increase the overall width of the profile by transverse stretching, and the process of transverse stretching A through hole will be formed in the center to facilitate the insertion and assembly of other profiles. This building profile can be stretched horizontally to a wider profile using narrow profile raw materials, so that compared with profiles of the same width, less materials are used. Thereby saving raw materials and reducing costs.

And because several reinforcing ribs are also arranged on the middle plate part, and each reinforcing rib is respectively located between each row of adjacent through holes, the reinforcing ribs can further increase the strength of the profile, and it is also convenient to install on the middle plate part. Protect the middle plate during transverse stretch forming to avoid excessive deformation of the middle plate during stretching.

And because described reinforcing rib is on the symmetry line of another row corresponding through hole, like this, this reinforcing rib can be used as the reference standard of through-hole forming, and simultaneously, the transverse position that each reinforcing rib reinforces is the same as the corresponding through hole. The positions correspond to each other, so that the strength of each part of the entire profile is more uniform.

And because the outer sides of the through holes on the middle plate are respectively provided with longitudinal ribs, the longitudinal ribs are connected with the corresponding reinforcing ribs, so that the longitudinal ribs can connect the reinforcing ribs as a whole, Thereby improving the strength of the profile as a whole and better satisfying the use of architectural decoration.

And because the free end of the reinforcing rib is set as a spherical end, the spherical end can effectively protect the middle plate and avoid cracking of the middle plate when the reinforcing rib is formed.

And because the through hole is a polygonal hole, wherein the through hole includes three connected straight hole sides on the middle plate, the angle between the three straight hole sides is 120°, and the vertex angle of each straight hole side is 120°. In this way, the through hole can be punched out with three straight hole edges during stamping and forming, and then the through hole is formed by transverse stretching, which is more convenient for forming.

Moreover, since the longitudinal flange is also provided with a reinforcing flange, which is parallel to the surface of the middle plate portion, the reinforcing flange can further increase the bending resistance of the profile.
