Abstract
The invention discloses a light corrosion-resistant composite steel structure beam and belongs to the technical field of steel structures. The light corrosion-resistant composite steel structure beam comprises H-shaped steel, wherein reinforcing plates are arranged on two surfaces of a web of the H-shaped steel at intervals, and the reinforcing plates on the two surfaces of the web are staggered; cross-shaped holes are formed in the web between the adjacent reinforcing plates; threaded holes are formed in the end parts of two flange plates of the H-shaped steel, and bamboo fiber plastic layers are arranged on the surfaces of the H-shaped steel and the reinforcing plates. The strength is greatly improved, and the carrying capacity is improved. The cross-shaped holes in the web can reduce the weight of the whole steel structure beam and also ensures the combining adhesive force between the steel structure beam and concrete or other building materials. By arranging the bamboo fiber plastic layers, a certain mechanical strength is ensured and wear resistance and corrosion resistance are achieved.
Description
Technical field
The present invention relates to long strands field, in particular to a kind of light anticorrosive composite steel structure beam.
Background technology
In building at present, be mostly reinforced concrete structure, cast-in-site, time-consuming, speed is slow, and heavier, also have be between adopt the steel such as H profile steel or C-type steel to be welded into skeleton as beam, achieve lightweight, but its intensity is relatively low, is difficult to comprehensively meet building demand.
Summary of the invention
The object of the present invention is to provide a kind of light anticorrosive composite steel structure beam, to solve the problem.
For realizing the object of the invention, the technical scheme of employing is: a kind of light anticorrosive composite steel structure beam, comprises H profile steel, and two surfaces of the web of described H profile steel are all arranged at intervals with stiffener, and stiffener on web two surfaces is interlaced; Web place between adjacent stiffening plates offers cruciform vent; The end opens of two frange plates of H profile steel has screwed hole; The surface of H profile steel and stiffener is provided with bamboo fibre plastic layer.
Further, described stiffener and H profile steel are welded to connect.
Further, described bolt hole is symmetrical relative to web.
The invention has the beneficial effects as follows, the stiffener that interleaved is arranged substantially increases intensity, improve supporting capacity, and the weight that cruciform vent can alleviate steel structure girder entirety offered by web, avoid too heavy, if fluid concrete etc. simultaneously, also assures that between this steel structure girder and concrete or other constructional materialss in conjunction with adhesive power, prevent from mutually departing from and reduce overall application life, bamboo fibre plastic layer both ensure that certain mechanical strength, had again wear-resisting and decay resistance.
Accompanying drawing explanation
Fig. 1 is the front view of light anticorrosive composite steel structure beam provided by the invention;
Fig. 2 is the top view of Fig. 1;
Fig. 3 is the sectional view at A-A place in Fig. 2.
Detailed description of the invention
Also by reference to the accompanying drawings the present invention is described in further detail below by specific embodiment.
Fig. 1, Fig. 2, Fig. 3 show light anticorrosive composite steel structure beam provided by the invention, comprise H profile steel 1, and two surfaces of the web of H profile steel 1 are all arranged at intervals with stiffener 2, and stiffener 2 on web two surfaces is interlaced; Web place between adjacent stiffening plates 2 offers cruciform vent 3; The end opens of two frange plates of H profile steel 1 has screwed hole 4; The surface of H profile steel 1 and stiffener 2 is provided with bamboo fibre plastic layer 5, and stiffener 2 and H profile steel 1 are welded to connect.Bolt hole 4 is symmetrical relative to the web of H profile steel 1, to install.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
