[0002] The loads of large equipment in a turbine room are heavy and often unevenly distributed across adjacent spans of continuous beams due to process layout requirements. Consequently, the frame beams, serving as mid-span supports for the continuous beams, are subject to significant torque due to unbalanced bending moments at both ends. However, to improve unit operating efficiency, ensure smooth and short pipeline layouts, and save investment, the turbine room's structural layout is subject to clear height requirements and column width limitations due to process layout requirements, making it impossible to meet the torsional requirements by significantly increasing the frame beam cross-section.

[0003] The purpose of the present invention is to solve the defects and shortcomings of the prior art. A horizontal armpit structure of the frame beam is designed to solve the problem of insufficient torsional resistance of the frame beam without affecting the process layout, so that the process pipeline can be arranged smoothly, the pipeline path is shortened, and investment is saved.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a horizontal axil structure of a frame beam, including an axil plate system and a steel bar system, the axil plate system includes an axil plate body respectively arranged on both sides of the frame beam, the axil plate body is used to connect the frame beam, the frame column and the continuous beam, and the thickness of the axil plate body is equal to the height of the continuous beam, the steel bar system includes multiple waist bars of the axil plate body and stirrups connected to the waist bars, and also includes oblique steel bars arranged at the top and bottom of the axil plate body. Through the joint cooperation of the axil plate system and the steel bar system, the bending moment in the continuous beam can be transferred to the frame column.

[0005] Preferably, the cross-section of the axil plate body is designed to be triangular in structure.

[0006] Preferably, one end of the oblique side of the axil plate body is connected to the midpoint of the frame column, and the other end is connected to the continuous beam.

[0007] Preferably, the angle between the hypotenuse of the armpit plate body and the central axis of the frame column is 45°.

[0008] Preferably, the two right-angled sides of the axil plate body are respectively connected to the frame column, the end of the frame beam and the part of the continuous beam close to the frame beam.

[0009] After adopting the above technical solution, the horizontal haunch structure of the frame beam provided by the present invention has the following beneficial effects:

[0010] (1) By utilizing the structure of the present invention, the support beams for important equipment such as the best machine in the steam engine room can adopt concrete continuous beams with better integrity, avoiding the connection hidden dangers between the steel secondary beams and the concrete frame beams, and ensuring the safe operation of the equipment.

[0011] (2) By utilizing the structure of the present invention, the requirements of the process professionals can be met without increasing the cross-section of the frame beams and columns, so that the process professionals can try their best to optimize the pipeline layout during design, improve the efficiency of the unit, and save investment.

[0012] In summary, the present invention utilizes two triangular horizontal axil plates to connect the continuous beam, the frame beam ends, and the frame columns, thereby changing the load transfer path so that the frame beam can meet the load-bearing requirements without increasing the height or width of the cross-section, thus providing a guarantee for the optimization of the process equipment and pipeline layout.

In all examples shown and discussed here, any specific values ​​should be interpreted as being merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0019] In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction.

Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0021] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0022] The present invention provides a horizontal haunch structure for a frame beam, such as Figure 1-2 As shown, it includes a haunch plate system and a steel bar system. The haunch plate system includes a haunch plate body 2 respectively arranged on both sides of the frame beam 1. The haunch plate body 2 is used to connect the frame beam 1, the frame column 3 and the continuous beam 4, and the thickness of the haunch plate body 2 is equal to the height of the continuous beam 4. The steel bar system includes multiple waist bars 5 of the haunch plate body 2 and stirrups 6 connected to the waist bars 5, and also includes oblique steel bars 7 arranged on the top and bottom of the haunch plate body 2.

[0023] Among them, the armpit plate body 2 is a concrete slab, and the cross-section of the armpit plate body 2 is designed as a triangular structure. One end of the hypotenuse of the armpit plate body 2 is connected to the midpoint of the frame column 3, and the other end is connected to the continuous beam 4. The angle between the hypotenuse of the armpit plate body 2 and the frame column 3 can be adjusted according to actual needs. Preferably, the angle between the hypotenuse of the armpit plate body 2 and the central axis of the frame column 3 is 45°, and the two right-angled sides of the armpit plate body 2 are respectively connected to the frame column 3, the end of the frame beam 3 and the part of the continuous beam 4 close to the frame beam 1.

[0024] The oblique steel bars 7 are main load-bearing steel bars. The oblique steel bars 7 , waist bars 5 , stirrups 6 and concrete axil plates work together to transmit torque to the frame columns 3 .

[0025] When a frame beam with a horizontal haunch structure is used, the force transmission path of the torque generated by the unbalanced bending moment is changed, so that the torque does not need to pass through the frame beam 1 but is directly transmitted to the frame column 3 by the haunch plate body 2 under bending, which greatly reduces the torque on the frame beam 1 and allows the frame beam 1 to be designed as a normal shear-bending member.

[0026] In summary, the present invention provides a horizontal armpit structure for a frame beam, which uses two triangular horizontal armpit plates to establish a direct connection between the continuous beam and the frame column, so that it can transfer the unbalanced bending moment generated by the load in the continuous beam, change the original force transmission path, avoid the influence of excessive torque on the frame beam, and enable the frame beam to meet the load-bearing requirements without increasing the height and widening the cross-section, while ensuring the net height requirements when arranging process equipment and pipelines.

[0027] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
