Abstract
The invention relates to an improved steel structure support beam, which is characterized by comprising two channel steels, wherein a vertical rib is arranged between the two channel steels, a fireproof structure is arranged between the channel steels and the vertical rib, the tops and the bottoms of the two channel steels are provided with steel plates, the channel steels and the steel plates are fixed through screw bolts, and steel plate gaskets are arranged between the channel steels and the steel plates. The improved steel structure support beam has the advantages that the structure is simple, the fixation is firm, the use and the installation are convenient, the fireproof effect is good, the integral intensity is strong, the anti-tearing capability of a load bearing panel is strong, and the cost performance is high.
Description
Technical field
The present invention relates to a kind of steel structure support beam, relate in particular to a kind of improved steel structure support beam.
Background technology
At present, the channel-section steel girder steel has the up and down level to become, and resistance to compression, bending resistance are effective, at certain twisting resistance, intensity is high, a large amount of ends that are difficult for, but channel-section steel is the easy pressure break of panel when heavy duty is frequent, makes the application life of steel plate short, and effect is bad, some steel plates all weld together usually, complex production process, inconvenient maintenance, precision is difficult to grasp, and enabling capabilities is low, has had a strong impact on result of use, for addressing the above problem, the spy provides a kind of new technical scheme.
Summary of the invention
The purpose of this invention is to provide a kind of improved steel structure support beam.
The technical solution used in the present invention is:
A kind of improved steel structure support beam, comprise two U-steels, be provided with vertical bar between described two U-steels, be provided with fire proof construction between described U-steel and vertical bar, described two U-steel tops and bottom are provided with steel plate, be bolted between described U-steel and steel plate, be provided with the steel plate packing ring between described U-steel and steel plate.
Described fire proof construction comprises fire prevention pad and fireprotection layer, and described fireprotection layer is arranged at fire prevention pad external surface.
Described steel plate is the yi word pattern steel plate.
Advantage of the present invention is: simple in structure, and fixation, easy to install and use, flameproof effect is good, and whole intensity is high, and load-bearing panel lear energy is strong, and cost performance is high.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Fig. 1 is structural representation of the present invention.
Fig. 2 is the sectional view of fire proof construction in Fig. 1.
Wherein: 1, U-steel, 2, vertical bar, 3, fire proof construction, 4, the yi word pattern steel plate, 5, bolt, 6, the steel plate packing ring, 7, the fire prevention pad, 8, fireprotection layer.
The specific embodiment
as depicted in figs. 1 and 2, the steel structure support beam of a modification of the present invention, comprise two U-steels 1, be provided with vertical bar 2 between two U-steels 1, be provided with fire proof construction 3 between U-steel 1 and vertical bar 2, fire proof construction 3 comprises fire prevention pad 7 and fireprotection layer 8, fireprotection layer 8 is arranged at fire prevention pad 7 external surfaces, two U-steel 1 tops and bottom are provided with yi word pattern steel plate 4, fixing by bolt 5 between U-steel 1 and yi word pattern steel plate 4, be provided with steel plate packing ring 5 between U-steel 1 and yi word pattern steel plate 4, simple in structure, fixation, easy to install and use, flameproof effect is good, whole intensity is high, load-bearing panel lear energy is strong, cost performance is high.
