Embodiment 1

[0066] A bolted honeycomb H steel beam such as figure 1 , figure 2 , image 3 , Figure 4 As shown, it is a honeycomb steel beam with horizontal oblong holes, including an upper T-shaped beam 1, a lower T-shaped beam 2, and bolts 5. The manufacturing method is carried out according to the following steps: first, the web of the H-shaped steel beam is figure 1 The cutting line 4 shown in the figure is cut to obtain figure 2 For the upper and lower T-beams shown, bolt holes are made at the crests of the webs of the upper and lower T-beams, where the webs of the upper and lower T-beams have flanges Parallel cut the straight section, and then displace the cut straight section of the upper T-beam web and the cut straight section of the lower T-beam web, keep the straight line parallel and align the two ends, and then use high-strength bolts for lap connection The inter-hole web is formed, and the honeycomb steel beam with horizontal long round holes is finally obtained. The H...

Embodiment 2

[0068] A bolted honeycomb H steel beam such as figure 1 , figure 2 , Figure 5 , Image 6 As shown, it is a circular-hole honeycomb beam, including an upper T-shaped beam 1, a lower T-shaped beam 2, a bolt 5, and a spliced ​​cover plate 6. Bolt holes are made at the cover plate, and high-strength bolts are used to connect the upper and lower T-beam webs with a single-side spliced ​​cover plate. For other references to Embodiment 1, details are not repeated here.

Embodiment 3

[0070] A bolted honeycomb H steel beam such as figure 1 , figure 2 , Figure 7 , Figure 8 As shown, it is a vertical oblong hole honeycomb steel beam, including an upper T-shaped beam 1, a lower T-shaped beam 2, a bolt 5, and a splicing plate 6. The width of the splicing cover plate is the same as that of the upper and lower T-shaped beam webs The length of the cutting straight line section is the same, bolt holes are made at the crests of the upper and lower T-beam webs and the spliced ​​cover plate, and high-strength bolts are used to connect the upper and lower T-beam webs with the help of a single-side spliced ​​cover plate. In this embodiment, the section height of the honeycomb steel beam is increased by splicing the cover plate on one side. For other references to Embodiment 1, details are not repeated here.

Abstract

The invention discloses a honeycomb H-shaped steel beam connected by bolts and a manufacturing method. The honeycomb H-shaped steel beam comprises an upper T-shaped beam body and a lower T-shaped beam body with the T-shaped cross sections. The upper T-shaped beam body and the lower T-shaped beam body are arranged to be in an H shape in an up and down symmetrical mode. Grooves with the same shape are uniformly formed in web plates of the upper T-shaped beam body and the lower T-shaped beam body. Bolt holes are formed in the two sides of each groove. The bolts penetrate through the bolt holes to splice the upper T-shaped beam body and the lower T-shaped beam body in a bolted mode. The honeycomb steel beam with holes in different shapes being formed in the web plates of the upper T-shaped beam body and the lower T-shaped beam body after splicing is formed. The problem that the honeycomb beam with the high section is inconvenient to transport is solved, at the time of transporting, the upper honeycomb beam body with the T-shaped section and lower honeycomb beam body with the T-shaped section can be transported directly, and after transported to a construction site, the two parts are assembled.

Description

technical field [0001] The invention relates to the related technical field of building steel structures, in particular to a bolt-connected honeycomb steel beam and a manufacturing method thereof. Background technique [0002] Honeycomb beam is a new type of steel structural member. In order to reduce the self-weight of the components and save steel, the web part of the shaped steel beam is cut along the curve, and welded in dislocation, and spliced ​​into round holes or hexagonal holes in the web, which increases the steel without increasing the amount of materials. The section height of the beam improves the bending rigidity and bearing capacity of the original solid web beam, and reduces the self-weight; at the same time, it is convenient to arrange pipeline threading to reduce the height of the building. Since it was used in engineering at the beginning of the 20th century, especially with the emergence of rolled H-shaped steel, honeycomb beams have been widely used in ...
