The walkway area is provided with a steel beam structure connected to the outer frame, the core tube and the steel columns installed on the outer frame. In the conventional design in the prior art, the main pipelines are concentrated in the walkway range, resulting in a relatively tight net height of the walkway and difficulty in pipe layout.

[0017] In order to solve the problem that the main pipelines are concentrated in the walkway, the walkway net height is relatively tight, and the pipe harness is difficult to arrange, the utility model provides a steel beam arm reduction structure, which not only solves the problem of tight walkway net height and difficult pipe harness arrangement, but also reduces the amount of steel and reduces the cost. The steel beam arm reduction structure is further described below with specific embodiments combined with the accompanying drawings.
[0018] like Figure 1 to Figure 2 As shown, the utility model provides a steel beam armpit reduction structure, which is used to be arranged between a core tube and an outer frame, the outer frame includes a frame body and a steel column and a cantilever beam fixedly installed on the frame body, the steel beam armpit reduction structure includes a first steel beam for hinged connection between the core tube and the frame body, a second steel beam for hinged connection between the core tube and the steel column, and a third steel beam for hinged connection between the core tube and the cantilever beam, the first steel beam, the second steel beam and the third steel beam all include a main beam 11 and a secondary beam 12 welded to the main beam 11;
[0019] There is a height difference between the bottom of the main beam 11 and the bottom of the auxiliary beam 12, and the bottom of the auxiliary beam 12 is higher than the bottom of the main beam 11, and a space for arranging pipelines is formed by the height difference;
[0020] A stiffening rib 2 is fixedly installed at the welding point between the main beam 11 and the auxiliary beam 12 to reinforce the weld.
[0021] The first steel beam includes a set of main beams 11 and a set of secondary beams 12, the main beams 11 are hinged to the frame body, and the secondary beams 12 are hinged to the core tube;
[0022] By reducing the volume of the secondary beam 12 connected to the core tube, while the volume of the main beam 11 connected to the frame body remains unchanged, the height difference can form a space for arranging pipelines; at the same time, the bearing capacity of the outer frame body is weaker than that of the steel column in actual application, so the main beam 11 hinged to the outer frame body is not changed, which also ensures that the main beam 11 can be used normally under force.
[0023] The second steel beam includes a set of main beams 11 and two sets of secondary beams 12. The two sets of secondary beams 12 are respectively arranged at both ends of the main beam 11 for hingedly connecting the steel column and the core tube.
[0024] By reducing the volume of the secondary beam 12 hinged to the steel column and the core tube without changing the volume of the middle section main beam 11, the overall bearing capacity of the second steel beam is ensured to be unaffected. At the same time, space for arranging pipelines is formed at both ends, which is conducive to pipeline arrangement.
[0025] The third steel beam includes a group of main beams 11 and a group of secondary beams 12. The main beams 11 are hinged to the cantilever beams, and the secondary beams 12 are hinged to the core tube.
[0026] The cantilever beam is set to have the same application conditions as the outer frame body, and the volume of the main beam 11 hinged to the cantilever beam is not changed, which is also to ensure that the main beam 11 can be used normally under load.
[0027] The cross sections of the main beam 11 and the auxiliary beam 12 are both "H" shaped or "I" shaped;
[0028] By designing the main beam 11 and the auxiliary beam 12 into an "H" shape or an "I" shape, the cross-sectional area of the two can be optimized, the strength-to-weight ratio is more reasonable, and the bending resistance is strong. When the volume of the auxiliary beam 12 is appropriately reduced, it will not have a significant impact on the overall load-bearing capacity of the steel beam 1.
[0029] The height difference between the bottom of the main beam 11 and the bottom of the auxiliary beam 12 is 5 cm to 10 cm;
[0030] By designing the height difference between the bottom of the main beam 11 and the auxiliary beam 12 to be 5 cm to 10 cm, it is not only beneficial to increase the clear height of the aisle and meet the current pipeline layout requirements, but also the volume reduction of the auxiliary beam 12 is not large, which will not affect the shear stress and the overall force-bearing use of the steel beam 1.
[0031] By reducing the lower volume of one end hinged to the core tube and the steel column, that is, the volume of the secondary beam 12, without affecting the overall stress of the steel beam 1, a height difference is created between the bottom of the secondary beam 12 and the bottom of the main beam 11, forming a space for arranging pipelines, thereby increasing the clear height of the aisle and meeting the requirements for integrated electromechanical piping. At the same time, by appropriately reducing the volume of the secondary beams 12 at both ends, the amount of steel used is reduced and the cost is reduced.
