Description

Technical Field

[0001] The utility model relates to the technical field of building structure engineering, in particular to a main plant frame supporting structure with a longitudinal single-beam and double-beam joint arrangement. Background Art

[0002] In thermal power plants, the coal bunker layout in front of the main powerhouse is one of the most commonly used layout schemes. The steam engine room, deaerator room and coal bunker room are arranged in parallel in front of the boiler to form a joint structure, which is one of the main layout forms of the main powerhouse of a thermal power plant. The optimization of the structural form of the main powerhouse is one of the most important contents in the structural design of a thermal power plant. The main powerhouse can usually adopt reinforced concrete structure or steel structure, and reinforced concrete structure is widely used due to its low cost and other advantages. Usually, the column cross-section of the main powerhouse of a large thermal power plant is large. In order to ensure the rigidity of the main powerhouse frame, two concrete frame beams need to be set in the longitudinal direction of the main powerhouse, that is, the weak axis direction of the column cross-section. At the same time, the double beam is also convenient for the layout of process pipelines.

[0003] In areas with high seismic fortification intensity, the applicable height of reinforced concrete frame structures in the specifications usually cannot meet the needs of process layout, so frame-shear wall or frame-steel support structure systems are often used. The process system layout in the main plant is relatively complex, and there are many pipelines and equipment, so it is difficult to arrange shear walls in the main plant, while the layout of steel supports is more flexible, so frame-steel support structure systems are often used. In order to facilitate construction and installation, the connection between steel supports and concrete frames is usually made of embedded parts, but due to the large load and stiffness of the main plant, the internal force generated by the earthquake is also large, and the selection and production of embedded parts is more difficult. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-5 The utility model discloses a main plant frame support structure with a longitudinal single-beam and double-beam joint arrangement, including a plant frame, the plant frame is composed of a plurality of reinforced concrete columns 1 and a plurality of reinforced concrete beams 2 arranged between two adjacent reinforced concrete columns 1; the reinforced concrete beams 2 include a single beam 21 and a double beam 22, a cross support 3 is arranged between two adjacent single beams 21, and the cross support 3 is in an X shape;

[0022] A plurality of embedded connectors 4 are provided on the reinforced concrete column 1 , and the four ends of the cross support 3 are connected to the reinforced concrete column 1 through the embedded connectors 4 .

[0023] In the utility model, the cross support 3 and the reinforced concrete column 1 are connected by embedded parts, so that the construction and installation of the cross support 3 can be carried out after the construction of the factory frame, which shortens the construction period of the factory frame and is conducive to speeding up the construction speed of the project. At the same time, the arrangement of the cross support 3 is relatively flexible, and the arrangement position can be flexibly adjusted according to the arrangement of the process pipeline; by adopting the combined arrangement of the longitudinal single beam 21 and the double beam 22, only the single beam 21 needs to be set at the position where the cross support 3 is arranged, so that the factory frame can reduce the longitudinal stiffness to a certain extent while meeting the overall stiffness, so that the structure has a certain ductility and better seismic resistance, and at the same time can reduce the amount of steel used and reduce the cost.

[0024] In the specific implementation, the factory building frame is composed of a transverse frame rack, a longitudinal frame and a longitudinal cross support 3. The transverse frame rack and the longitudinal frame are both composed of reinforced concrete columns 1 and reinforced concrete beams 2; the longitudinal frame is a joint arrangement of a single beam 21 and a double beam 22, and the cross support 3 is arranged to adapt to the longitudinal single beam 21. The longitudinal frame can be divided into four rows of A, B, C, and D. Among them, the load of row A is small and the impact on the process layout is small. The arrangement of the cross support 3 mainly considers the impact of the busbar and the vehicle. The ends of rows B, C, and D have little impact on the process layout. The cross support 3 mainly considers the impact of the building passage. At the same time, the arrangement of the cross support 3 along the height direction can be flexibly adjusted according to the arrangement of the process pipeline to ensure that the cross support 3 is arranged in a continuous span.

[0025] In one embodiment, the top section of the single beam 21 is an I-shaped structure, and the top section of the double beam 22 is an =-shaped structure.

[0026] In one embodiment, the cross support 3 is composed of a long support 31 and two short supports 32, and both ends of the long support 31 and one end of the short support 32 are provided with a first splicing joint for connecting to the embedded connecting piece 4, a connecting piece is provided on the long support 31, and a second splicing joint for connecting to the connecting piece is provided at one end of the short support 32 away from the first splicing joint.

[0027] Such a design ensures that the cross supports 3 do not need to be arranged in a standard X shape during installation, and the number of long supports 31 and short supports 32 can be flexibly increased or decreased according to the requirements of the process pipeline to arrange them in different shapes.

[0028] In one embodiment, mounting holes are provided on the first splicing joint and the embedded connecting part 4, and a rotation auxiliary part 5 is arranged in the mounting hole. The rotation auxiliary part 5 includes a rotating shaft section that is consistent with the aperture of the mounting hole. The length of the rotating shaft section is not less than the sum of the depths of the two mounting holes. An anti-slip section is provided at one end of the rotating shaft section. The anti-slip section is disc-shaped, and the outer diameter of the anti-slip section is larger than the aperture of the mounting hole. A stop section is provided at the other end of the rotating shaft section. The stop section is a truncated cone with a cross-shaped groove in the middle. The outer diameter of the stop section close to the rotating shaft section is larger than the aperture of the mounting hole, and the outer diameter of the stop section away from the rotating shaft section is smaller than the aperture of the mounting hole.

[0029] With this design, when installing the long support 31 or the short support 32, the end corresponding to the embedded connecting piece 4 can be connected together through the rotating auxiliary piece 5 first, so that the long support 31 or the short support 32 after connection can be rotated to adjust the position of the other end without being separated from the embedded connecting piece 4, which is convenient for the installer to quickly align the installation hole and improve the construction convenience.

[0030] In one embodiment, at least two first insertion holes for bolt installation are provided on the first splicing joint, and at least four second insertion holes for bolt installation are provided on the embedded connecting member 4, and the plurality of second insertion holes are distributed in a ring shape with the center of the installation hole.

[0031] With this design, the installation of cross supports 3 at different installation angles can be achieved by inserting bolts into different second holes, so that when installing the embedded connectors 4, uniform specifications and models can be used to reduce the construction difficulty of the installers. At the same time, it also avoids the problem of different models of the embedded connectors 4 affecting subsequent construction after the wrong installation position.

[0032] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.
