[0002] As people's living standards improve, their requirements for indoor space in buildings are also gradually increasing. At present, for the design of multi-story or high-rise steel structure buildings, steel beam components with web openings can be used instead of solid web beam components, allowing various pipelines or equipment lines to pass through the web openings, reducing the occupation of building space by pipeline equipment and significantly increasing the net height of indoor space.

However, there will often be a certain position deviation when the pipeline is installed on site, which may cause the pipeline to fail to pass through the beam plate according to the designed route, increasing the time for on-site rectification.

[0031] Example 1

[0032] refer to Figures 1 to 4 As shown in the figure, a steel beam opening structure is shown, and the steel beam opening structure includes an outer steel beam 100 and an inner steel beam 200, wherein the outer steel beam 100 is an H-shaped steel and the inner steel beam 200 is an H-shaped steel.

[0033] Preferably, a beam plate hole 102 is provided on the outer steel beam web 103 of the outer steel beam 100. The inner steel beam 200 is nested in the beam plate hole 102 and can slide along the extension direction of the beam plate hole 102. An inner steel beam hole 206 is provided on the inner steel beam web 204 of the inner steel beam 200, and the size of the inner steel beam hole 206 matches the size of the beam-penetrating pipe 300 to be passed through.

[0034] Furthermore, the inner steel beam hole 206 is a rectangular frame structure, or the inner steel beam hole 206 has the same shape as the beam-penetrating pipe 300 to be passed through.

[0035] Preferably, the beam-slab hole 102 is formed by first determining the spatial position of the beam-penetrating pipe 300 passing through the outer steel beam 100, using a rectangular frame line as the boundary range of the beam-penetrating pipe 300, extending the critical lines on both sides outward by 5-10 cm in the horizontal direction, and using the frame line as the cutting size to cut the outer steel beam web 103 to form a rectangular hole, which is the beam-slab hole 102. Then, beam-slab chute 101 is opened at the top and bottom of the left and right sides of the beam-slab hole 102. The four beam-slab chute 101 have the same size, and the length of the opening is consistent with the distance extended outward from the critical line before the hole is opened.

[0036] Preferably, the inner steel beam 200 is composed of an upper wing plate 201, a lower wing plate 202, an inner steel beam web 204 and a partition plate 203, and the area surrounded by the upper wing plate 201, the lower wing plate 202 and the partition plate 203 is a hollow area, that is, the inner steel beam hole 206.

[0037] Preferably, the upper wing plate 201 is clamped in the beam plate slide groove 101 at the top of the beam plate hole 102, the lower wing plate 202 is clamped in the beam plate slide groove 101 at the bottom of the beam plate hole 102, and the inner steel beam 200 can slide along the extension direction of the beam plate slide groove 101.

[0038] Furthermore, in the cross-sectional direction, there is a distance deviation between the center line of the inner steel beam web 204 and the center line of the inner steel beam 200 , and the deviation size is half of the thickness of the outer steel beam web 103 .

[0039] Preferably, the upper wing plate 201 and the lower wing plate 202 are further provided with a plurality of sliding wheels 207, and the sliding wheels 207 and the inner steel beam web 204 are respectively located on both sides of the outer steel beam web 103, and complete the clamping of the outer steel beam web 103. This ensures that the inner steel beam 200 will not fall off during the sliding process on the outer steel beam 100.

[0040] Furthermore, the upper wing plate 201 and the lower wing plate 202 are provided with shaft holes 205 , and each sliding wheel 207 is fixed to the upper wing plate 201 and the lower wing plate 202 through the shaft holes 205 .

[0041] The position relationship of the inner and outer steel beams on the cross section is as follows: Figure 5 As shown, the center lines of the two steel beams coincide, the inner steel beam web 204 is in close contact with the outer steel beam web 103, and the sliding wheel 207 is installed on the upper and lower wing plates of the inner steel beam, and its wheel edge is in close contact with the other side of the outer steel beam web.

[0042] When installing the inner steel beam 200, first hoist the inner steel beam 200 to the corresponding beam plate hole 102 of the outer steel beam 100, keep the hoisting state and push the inner steel beam 200 into the beam plate hole 102, so that the inner steel beam web 204 is close to the outer steel beam web 103, and then install the sliding wheel 207 at the wing plate shaft hole of the inner steel beam 200 to complete the installation of the component.

[0043] During the installation of electromechanical pipelines, when there is a small deviation between the actual position of the pipeline passing through the beam and the designed position of the steel beam hole, the inner steel beam 200 can be moved horizontally to allow the pipeline to completely pass through the steel beam area, eliminating the need for secondary adjustments to the pipeline installation at the construction site.

[0044] That is, through the structural setting of the steel beam opening structure of the utility model, the beam-penetrating pipe 300 to be passed through can effectively pass through the steel beam under the condition of a certain distance deviation, and the effective limit of each beam-penetrating pipe is maintained, that is, each beam-penetrating pipe 300 does not pass through a single large-sized hole in a scattered manner.
