Description

Technical Field

[0001] The invention relates to the technical field of petrochemical industry, in particular to a triangular frame truss beam which is convenient for horizontal transportation in a tower and a use method thereof. Background Art

[0002] With the increasing requirements of the state on the petrochemical industry in the fields of environmental protection and energy conservation, as well as the current demand for maximizing corporate benefits, large-scale equipment has become a major development trend in the petrochemical industry. Whether it is a packed tower or a plate tower, for large-diameter towers, due to the large span and weight of internal parts such as tower plates, liquid distributors, and packings, the support beam will produce a large deflection. The reasonable design of the support beam plays a significant role in fully exerting the performance of the tower internals. The tower equipment has relatively strict requirements on the horizontality of the tower internals. If the support beam is improperly designed, it will directly affect the production capacity and efficiency of the tower. If you want to simply improve the efficiency of the tower, you hope that the strength of the tower internals is as high as possible and the deflection is as small as possible. However, if the strength is high and the deflection is too small, the thickness of the tower internals and the cross-sectional size of the support beam will increase, which will consume too much material. With the development of large tower equipment, the disadvantages of using I-beams and other steel beams have become increasingly prominent, especially in large towers over 7 meters. In order to ensure the requirements of strength and deflection, the height and width of I-beams and other steel beams have doubled, resulting in excessive weight of the beams, large space occupation, and serious impact on the flow state and mass transfer effect of gas-liquid two-phase in the tower. Therefore, the support beams in large towers are gradually replaced by truss beams such as I-beams.

[0003] The existing truss beam structure is generally a welded structure, which is mainly composed of two or more parallel chords and vertical rods or diagonal rods or fixed distance rods welded between the parallel chords. This kind of truss beam is generally not accessible from the manhole, and it is required to be delivered to the tower body factory in advance and installed in the tower before the last weld of the tower body is welded. The tower body with the truss beam installed needs to be transported to the site with the tower body and then other tower internals that can be entered from the manhole can be installed. For tower bodies with large tower diameters, since horizontal transportation is generally adopted during transportation, it is very inconvenient for ordinary truss beams. The advantages of the tower are that the vertical strength and stability of ordinary truss beams are very good, while the horizontal tower body is equivalent to a flat state for the truss beams that have been installed in the tower. The rigidity of the large-span truss beams in the horizontal tower body is very poor when installed, and the lateral deformation of the truss beams is further increased due to the bumps during transportation, which will cause the bolt holes on the beams to not be connected with the bolt holes of the internal parts after arriving at the site. Under normal circumstances, the truss beams in the tower need to be temporarily supported by an additional support frame to ensure the normal use of the truss beams after being transported to the site. This will consume a lot of manpower, material resources, and financial resources, and will result in a relatively long transportation cycle. Therefore, there is an urgent need for a triangular frame truss beam that is high in strength, good in rigidity, good in stability, convenient in transportation, and can save labor costs, which is convenient for horizontal transportation in the tower.

[0004] Triangular frame truss beams are widely used in steel structure facilities such as buildings and bridges, and the truss span can reach tens of meters. However, the triangular frame truss beams used as support beams in towers are very rare, and this truss beam is different from the triangular frame truss beams in the construction industry. On the one hand, this truss beam is just a pure steel structure beam that is not combined with reinforced concrete, and the support position is not as random as that in the construction industry due to the influence of the tower structure and support components. On the other hand, the deflection requirements of the support beams in the tower are more stringent, and the upper surface of the beam must be a horizontal structure to ensure that the tower components are stably placed on the truss beams. Summary of the invention

[0015] A method for using a triangular frame truss beam. During the tower body assembly process, the main beams are first arranged in an isosceles triangle and fixed in the tower to ensure that the upper surface of the main beams is horizontal, so as to facilitate the subsequent overlap of the tower internal components; then, the web bars are installed to connect with the main beams to ensure that the centroid line of the web bars and the centroid line of the main beams remain in the same plane to provide stable structural support; then, the connecting plate 1 is welded and fixed to both ends of the main beam, and connected to the connecting plate 2 welded on the tower body by bolts to achieve a stable connection with the tower body; thereafter, the support plate is installed and overlapped with the support welded and fixed on the tower body, and fixed by bolts to ensure the load-bearing of the components in the tower; at the same time, the support plate is installed on the support plate Rib plates are installed to enhance their bearing capacity; bolt holes are then opened at the upper chord position of the truss beam to facilitate connection with the tower plate; next, when supporting the filler support grid, cross limit plates are welded to prevent the grid blocks from moving during operation; in addition, a support assembly is provided, including support plate one, a buffer plate and support plate two, and the outer wall of support plate one is fitted to the lower end of the outer wall of the support, and connected by bolts one and two to ensure the stability of the overall structure; finally, the support rod is fixed to support plate one to further enhance the support strength, ensure that the main beam remains stable during transportation and operation, optimize the flow effect of gas and liquid in the tower, reduce flow resistance, and improve overall utilization efficiency.

[0016] Working principle: It relies on the triangular frame composed of main beams and web members. The main beams are arranged in an isosceles triangle, with one main beam on the top and two main beams on the bottom. They are connected at a certain angle through web members to enhance the overall stability and load-bearing capacity. The connecting plate 1 is located at both ends of the main beam and provides a bolt connection with the connecting plate 2 to ensure that the main beam is firmly fixed on the tower body. The support plate is set on the main beam and is connected to the support by bolts to bear the weight of the components in the tower, ensuring the stability of the structure. At the same time, the rib plate enhances the strength of the support plate, making the connection between the main beam and the support plate more secure. The cross-section design of each main beam is based on strength calculation to ensure that the upper surface of the upper chord main beam remains horizontal, which is conducive to the smooth overlap of the tower components and the support. Support plate 1 is connected to the support, and the pressure applied to the support is dispersed through the buffer plate, and connected to support plate 2, which further enhances the supporting capacity of the main beam and avoids deformation. The support rod and the fixed plate play a stabilizing role in the support assembly, so that the structure maintains good stability during transportation and installation. Arc plate 1 and arc plate 2 effectively disperse the pressure of the main beam on support plate 2 and reduce the impact of concentrated loads. Bolts 1 and bolts 2 are easy to install and disassemble through handles, so that the entire structure can be quickly adjusted when needed. This design not only improves the circulation efficiency of gas and liquid in the tower and reduces flow resistance, but also optimizes the transportation and installation process, reduces costs, and ensures strength and stability in large tower diameter applications.

[0017] The present invention provides a triangular frame truss beam that is convenient for horizontal transportation in a tower. It has the following beneficial effects:

[0018] 1. The present invention has three main beams arranged in a triangular shape, one main beam on the top and two on the bottom, arranged in parallel in an isosceles triangle, a web is arranged between every two main beams, the web forms a certain angle with the main beams to form a stable triangular structure, and both ends of each main beam are connected to the connecting plate and the support, which not only has high strength, good rigidity, high stability, and good permeability, but also overcomes the traditional truss beam installation and design method, and well guarantees the strength and rigidity requirements of the supporting tower internals. At the same time, the size of the cross-section of the truss beam main beam is greatly reduced, saving production costs. At the same time, it can better ensure the flow area of ​​gas and liquid in the tower, increase the lateral mixing of gas and liquid in the tower, reduce the gas phase flow resistance, and better reduce the pressure drop in the tower.

[0019] 2. The present invention overcomes the disadvantage that the existing truss beam needs to be temporarily built with the tower body during horizontal transportation to the site to support the truss beam to avoid large deformation of the truss beam during transportation. The triangular frame truss beam can be transported to the site with the tower body after being installed in advance. There is no need for the cumbersome process of temporarily building an additional frame support, which greatly shortens the installation and transportation cycle and greatly reduces the transportation cost and labor cost.

[0020] 3. The present invention further improves the stability of the two main beams and the supports at the bottom through the support assembly, and can be used in plate towers with large tower diameters as well as in packed towers. If the tower diameter is too large, the stability of the existing truss beams will not be guaranteed, while the triangular frame truss beams have excellent strength, rigidity and stability and are not limited by the maximum tower diameter.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Embodiment 1:

[0032] Please see attached Figure 1 - Attachment Figure 6 The embodiment of the present invention provides a triangular frame truss beam that is convenient for horizontal transportation in a tower, including: a main beam 1, which is connected with a web member 2, and the outer wall of the main beam 1 is connected with a connecting plate 3; a support plate 5, the outer wall of which is arranged on the main beam 1, and the upper surface of the support plate 5 is connected with a rib plate 4; there are three main beams 1, which are arranged in a triangular shape, one main beam 1 is arranged in parallel with two main beams 1 at the top and the bottom in an isosceles triangle, a web member 2 is arranged between every two main beams 1, the web member 2 is connected to the main beam 1 through a connecting plate 3 at a certain angle or is directly connected to the main beam 1, and is arranged in a triangular shape with the main beam 1, and a connecting plate 3, a support plate 5 and a rib plate 4 are arranged at both ends of each main beam 1, the connecting plate 3 is connected to the connecting plate 2 6 welded and fixed on the tower body by bolts, the support plate 5 is overlapped with a support 7 welded and fixed on the tower body, and is connected and fixed to the support 7 by bolts, thereby realizing the stable setting of the truss beam; a fixing component, which is connected to the support 7 and is used to provide support for the support 7 and the main beam 1.

[0033] The main beams 1 are generally set to be three, one on the top and two on the bottom, arranged in an isosceles triangle in space. The three main beams 1 are parallel to each other, and the two main beams 1 at the bottom are on the same horizontal plane and parallel to the upper main beam 1. The cross-sectional dimensions of the main beams 1 can be determined by strength calculation, and the cross-sectional dimensions can be the same or different, but the upper surface of the upper chord main beam 1 is required to be a horizontal structure to ensure that the tower internals can be smoothly overlapped and the horizontality of the tower internals can be ensured. The structure of the main beam 1 can adopt T-beams or other cross-section beams, wherein the T-beams can be finished T-beams or those formed by welding steel plates. The T-beam may be a T-beam composed of angle steel beams welded back to back; other cross-section beams include round tubes or I-beams composed of channel steels welded back to back, and symmetrical cross-section beams composed of other steel sections welded back to back. When the main beam 1 is a cross-section beam composed of back-to-back channel steels or angle steels, the connecting plate 3 should be clamped in the gap between the steel sections welded back to back on the main beam 1 and welded. This connecting plate 3 connects the symmetrical cross-section beams on the one hand, and facilitates the connection between the main beam 1 and the web 2 on the other hand. The centroid line of the web 2 between every two main beams 1 is aligned with the centroid of the main beam 1 connected. The center line should be kept in the same plane and intersect with the main beam 1; the web member 2 is a steel section or a round tube, and the angle between the web member 2 and the main beam 1 is between 0° and 180°. The connecting plates 3 at both ends of the main beam 1 have at least two oblong holes at each end, and a support plate 5 is arranged at the bottom of the connecting plate 3, and rib plates 4 are arranged on both sides of the connecting plate 3 to connect the support plate 5 and the main beam 1, wherein the support plate 5 is provided with circular holes at both sides of the connecting plate, and the circular holes on the support plate 5 are used as bolt holes to be connected to the support 7 welded on the tower body by bolts, and the connecting plate 6 is also provided with a connection hole The connecting plate 2 6 has bolt holes that match the plate 3. When the connecting plate 2 6 is installed, one end without bolt holes is welded to the tower body, and the other end is connected to the connecting plate 3 with oblong holes at both ends of the truss beam main beam 1 by bolts. A tower plate 10 is arranged above the connecting plate 3. When the tower plate 10 is supported by the triangular frame truss beam, the truss beam upper chord main beam 1 needs to have bolt holes corresponding to the bolt holes of the supported tower plate 10; when the truss beam supports the filler supporting grid 8, the truss beam upper chord needs to weld a cross limit plate 9 between the grid blocks to prevent the grid blocks from moving during operation.

[0034] Specifically, the main beams 1 are generally set to be three, one on the top and two on the bottom, forming an isosceles triangle structure to ensure their mutual parallelism in space. The two main beams 1 below are on the same horizontal plane and parallel to the upper main beam 1, thereby improving the overall stability and bearing capacity. The cross-sectional dimensions of the main beam 1 are determined by strength calculations. Although the same or different cross-sectional dimensions can be selected, the upper surface of the upper chord main beam 1 is required to remain horizontal to ensure that the tower internals can be smoothly overlapped, thereby improving installation accuracy and structural safety. The main beam 1 can adopt a variety of cross-sectional forms, such as T-beams, circular tubes or other symmetrical cross-sectional beams. The T-beams can be finished products or welded from steel plates. This flexibility allows the structure to be optimized according to different application requirements.

[0035] When the main beam 1 is made of back-to-back channel steel or angle steel, the connecting plate 3 is clamped in the welded steel gap of the main beam 1 to enhance the rigidity and stability of the connection, while promoting the effective connection between the main beam 1 and the web member 2. The centroid line of the web member 2 between every two main beams 1 is kept in the same plane as the centroid line of the main beam 1 and intersects. This design ensures the uniformity of the force of the structure. The web member 2 can be a steel section or a round tube, and the angle between it and the main beam 1 can vary between 0° and 180°, thereby making the structure more flexible in dealing with different external loads.

[0036] The connecting plates 3 at both ends of the main beam 1 are provided with multiple oblong holes to facilitate adjustment of the connection accuracy with the tower body. At the same time, a support plate 5 is provided at the bottom, and the connection strength with the main beam 1 is enhanced by the rib plate 4, so that the fit between the support plate 5 and the main beam 1 is more stable. The circular holes opened on the support plate 5 are used as bolt holes to ensure that it can be safely connected to the support 7 welded on the tower body, providing reliable support.

[0037] The bolt holes designed on the connection plate 2 6 match the connection plate 1 3, further enhancing the connection reliability between the main beam 1 and the tower body. At the same time, the coordination between the tower plate 10 configured above the connection plate 1 3 and the upper chord main beam 1 of the truss beam ensures that it can effectively bear various loads in the tower. In addition, when the truss beam supports the filler support grid 8, the cross limit plate 9 is welded between the grid blocks to effectively prevent the displacement of the grid blocks during operation, thereby enhancing the stability of the overall structure.

[0038] Please see attached Figure 1 - Attachment Figure 3The fixing assembly includes a support plate 11, the outer wall of the support plate 11 is attached to the lower end of the outer wall of the support 7, the inner thread of the support plate 11 is connected with a bolt 18, the outer wall of the bolt 18 is penetrated into the interior of the support 7, the upper surface of the support plate 11 is fixed with a buffer plate 12, the upper surface of the buffer plate 12 is fixed with a support plate 2 13, the lower surface of the support plate 2 13 is attached to the lower surface of the main beam 1, the inner thread of the support plate 2 13 is connected with a bolt 2 19, the bolt 18 and the bolt 19 are connected. There is a handle 20 inside the bolt 19, which can be rotated to facilitate the removal of the bolt. An arc plate 16 is fixed under the support plate 13, and an arc plate 17 is fixed under the support plate 13. The arc plate 16 and the arc plate 17 are used to disperse the pressure of the main beam 1 on the support plate 13. A support rod 14 is fixed to the lower surface of the buffer plate 12, and the lower surface of the support rod 14 is fixed to the upper surface of the support plate 11. A fixing plate 15 is fixed on the support plate 11.

[0039] Specifically, the outer wall of the support plate 11 fits tightly with the outer wall of the support 7, so that it can effectively transmit force when bearing the gravity of the main beam 1 and other external loads. The thread inside the support plate 11 is connected to the bolt 18, and the bolt 18 is passed through the inside of the support 7 to ensure the tightness and stability of the overall assembly, thereby avoiding looseness or displacement that may occur during operation. A buffer plate 12 is installed on the upper surface of the support plate 11. The function of the buffer plate 12 is to absorb and disperse the vertical pressure from the main beam 1, thereby reducing the impact of direct impact on the supporting structure.

[0040] The support plate 2 13 fits tightly against the lower surface of the main beam 1, further improving the stability of the overall structure. The internally threaded bolts 2 19 and bolts 1 18 together form an adjustable connection system. By rotating the handle 20, the operator can easily remove and install the bolts, which improves the convenience of maintenance. The arc plates 1 16 and 17 below the support plate 2 13 are designed to disperse the pressure exerted by the main beam 1 on the support plate 2 13. This arc structure effectively enhances the load distribution, so that the support plate 2 13 can more evenly withstand forces from different directions, thereby reducing the potential risks caused by local stress concentration.

[0041] In addition, the support rod 14 fixed on the lower surface of the buffer plate 12 not only provides additional support, but also enhances the rigidity of the overall assembly. The combination of the support rod 14 and the support plate 11 provides the structure with stronger bending resistance and effectively improves the overall stability. This design shows good adaptability and ease of use in construction and later maintenance, and can cope with operational requirements in different environments.
