Example Embodiment

[0065] Example 1

[0066] A bolted honeycomb H steel beam, such as figure 1 , figure 2 , image 3 , Figure 4 As shown, it is a horizontally long round hole honeycomb steel beam, including upper T-shaped beam 1, lower T-shaped beam 2, and bolts 5. The manufacturing method is as follows: First, the H-shaped steel beam web figure 1 The cutting line 4 shown is cut to obtain figure 2 The upper T-shaped beam and the lower T-shaped beam are shown. Bolt holes are made at the wave crests of the upper T-shaped beam and the lower T-shaped beam web. The upper T-shaped beam and the lower T-shaped beam have flanges on the webs Cut straight sections in parallel, and then lap the cut straight sections of the upper T-shaped beam web and the cut straight sections of the lower T-beam web through positional misalignment, keep the straight lines parallel and aligned at both ends, and then use high-strength bolts for lap connection The inter-hole web is formed, and the horizontally long round-hole h...

Example Embodiment

[0067] Example 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 upper T-shaped beam 1, lower T-shaped beam 2, bolts 5, splicing cover plate 6, and the wave crest and splicing of the upper and lower T-shaped beam webs of the honeycomb steel beam Bolt holes are made at the cover plate, and high-strength bolts are used to connect the upper and lower T-beam webs with the single-sided splicing cover plate. Others refer to Embodiment 1, which will not be repeated here.

Example Embodiment

[0069] Example 3

[0070] A bolted honeycomb H steel beam, such as figure 1 , figure 2 , Figure 7 , Picture 8 As shown, it is a honeycomb steel beam with vertical oblong holes, including upper T-shaped beam 1, lower T-shaped beam 2, bolts 5, and splicing plate 6. The width of the splicing cover plate and the upper and lower T-shaped beam webs The length of the cutting straight section is the same. Bolt holes are made at the wave crests of the upper and lower T-beam webs and the splicing cover plate, and high-strength bolts are used to connect the upper and lower T-beam webs with the single-side splicing cover plate. In this embodiment, the section height of the honeycomb steel beam is increased by splicing the cover plate on one side. Others refer to Embodiment 1, which will not be repeated here.

Abstract

The invention discloses a bolt-connected honeycomb H-steel beam and a manufacturing method thereof, comprising an upper T-shaped beam and a lower T-shaped beam with a T-shaped cross section, and the upper T-shaped beam and the lower T-shaped beam are symmetrically arranged up and down Form an H shape; and grooves of the same shape are evenly provided on the webs of the upper T-shaped beam and the lower T-shaped beam, and bolt holes are arranged on both sides of each groove, and the bolts pass through the The bolt holes of the upper and lower T-beams are bolted together, and the webs of the upper T-beam and the lower T-beam after splicing form honeycomb steel beams of different pass types. It solves the problem of inconvenient transportation of high-section honeycomb beams. During transportation, the upper and lower parts of T-shaped section honeycomb beams can be directly transported, and the two parts can be assembled when transported to the construction site.

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 ...
