Description

steel composite structure

The present invention relates to a section steel composite structure technology, specifically, the present invention is a section steel structure technology which is easy to manufacture and integrally formed, and has a stable structure and is suitable for supporting and erecting various pipelines.

Steel structure buildings have many advantages such as light weight, good seismic performance, industrial production, and prefabricated installation. Therefore, they are often used in various modern buildings, especially in the design of high-tech factories. The use of steel structure buildings can achieve a wide application space. And it can greatly change with various building forms and have a higher level of seismic structural strength.

The steel structure buildings in the conventional technology are composed of various steel sections joined to each other, and the joints are usually bolted as a combination method, but the more bolt holes, the worse the production efficiency of the section steel, and affect the rigidity, strength and corrosion resistance of the section steel , so that the section steel is vulnerable to damage, deformation or corrosion by external forces, resulting in an impact on the overall safety of the building.

And when the various steel sections are combined by welding, the combined steel structure is often unstable due to insufficient weld beads, the connection is not tight enough, it is easy to separate and loose, and it cannot support the building structure for a long time or effectively prevent earthquakes.

Based on the above-mentioned purpose, the purpose of this model is to provide a composite structure of section steel, which includes: a section steel, which is an elongated structure formed by integral punching of steel plates, and the section steel has a back plate and at least one structure connected to the back plate. Side plate; wherein, there are a plurality of welding parts on the back plate; wherein, the number of section steel is at least two, and the section steel is arranged symmetrically to each other, and each of the back plates of the section steel is welded to each other by these welding sections; wherein, each of the welding sections is spaced The distance is 200~300mm.

Please refer to Fig. 1 to Fig. 3, what is depicted in the figure is the first embodiment of the new type steel composite structure, the elongated structure body that shape steel plate 10 is integrally punched into shape and process, the total length of shape steel 10 is 3000～ Between the range of 10000mm, the overall length of the steel 10 in this embodiment is 6000mm, the thickness is 2.0mm, the height is 41mm, and the width is 40mm. The section steel 10 has a back plate 11 and at least one side plate 12 connected with the back plate 11. There are a plurality of welds 13 at the central position of the back plate 11. In this embodiment, there are 22 welds 13, and the welds 13 are from The front end of the backboard 11 extends to the rear end at intervals.

The profiled steel composite structure is composed of at least two profiled steels 10 , each profiled steel 10 is arranged symmetrically with each other, with the back plate 11 facing the back plate 11 and connected with each other through the back plate 11 .

The shaped steel 10 can be one of C-shaped steel, L-shaped steel, H-shaped steel, or square steel or a combination of two or more. In this embodiment, the shaped steel 10 is composed of C-shaped steel. The self-weight of C-shaped steel is lighter than other shaped steels, and The production is fast and convenient, and it can save a lot of steel while effectively carrying the weight.

The C-shaped steel has a back plate 11 and two side plates 12 arranged symmetrically on both sides of the back plate 11 and connected with the back plate 11 . Each section steel 10 faces the backboard 11 with the backboard 11, and utilizes the welded part 13 on each backboard 11 to be welded together, and the length of each welded part 13 is 30mm, and is arranged at intervals from each other, and the distance between the welded parts 13 is It is 252mm, and is set evenly from the front end of the steel 10 to the rear end of the steel 10. And the shortest distance from the welding part 13 to the front end 14 of the shaped steel 10 is 20 mm, and the shortest distance from the welded part 13 to the rear end 15 of the shaped steel 10 is 30 mm.

After the steel sections 10 are welded to each other by the welding part 13, the two back plates 11 are tightly joined together, and the combined structure of the new type steel strengthens the number of the welding parts 13, so that the number of welding points between the steel sections 10 increases, and the tightness of the combination of the steel sections 10 is improved. High, but can strengthen the structural strength of the combined steel 10, and because no bolts are used, the structural production of the steel 10 is simple, easy and fast, and the strength of the steel 10 will not be damaged and weakened by the opening of the bolts.

The steel 10 raw material of the new type steel composite structure further uses environmentally friendly green building materials. In addition to meeting the certification requirements of domestic green building materials, it also meets the high-standard certification standards of the EU RoHS (Restriction of Hazardous Substances) and avoids the use of materials containing harmful substances. Raw materials and alloy element materials of high concern in the manufacturing process are reduced, and the use of restricted substances that have a significant impact on the environment is also reduced. Therefore, it can meet the requirements of building material safety regulations for many large-scale scientific and technological factories and buildings.

The new type steel composite structure can be used in the construction of modern high-tech factory buildings, especially in the construction of modern high-tech factory buildings, and cooperates with various pipelines in the factory buildings because of the reinforced number of welded parts 13 as the combination points of the steel 10 groups, and the combination method of elastic changes. Supporting the erection mode and combining them into different types not only enables the construction to be carried out quickly and effectively, but also has a higher bearing capacity than ordinary steel combinations.
