Description

Technical Field

[0001] The utility model belongs to the technical field of steel structures, and particularly relates to a structure of a sub-shaped main arch member. Background Technique

[0002] In the field of steel structure buildings, especially in the construction of complex structures such as large exhibition halls, bridges, and stadiums, there are extremely high requirements for the strength, stability, and manufacturing precision of components. As an important load-bearing and supporting structure, the design and manufacturing process of the sub-shaped main arch member directly affect the stability and safety of the overall structure.

[0003] Traditional arched member structures often adopt a single web or a complex box-shaped cross-section. These structures may have problems such as stress concentration, material waste, or difficult processing when bearing bending moments, shear forces, and torques. Summary of the Invention

[0004] The purpose of the utility model is to provide a structure of a sub-shaped main arch member for the problems existing in the prior art.

[0005] To achieve the above purpose, the following technical solution is adopted in the utility model: A structure of a sub-shaped main arch member includes a pair of webs, a partition is provided between the pair of webs, stiffening plates are provided on both sides of the partition, flange plates are respectively installed on both sides of the webs, a gusset plate is provided between the pair of flange plates, and the gusset plate is connected to the stiffening plate.

[0006] By adopting the above technical solution, through its unique design, the structure of the sub-shaped main arch member realizes multiple functions such as enhancing the overall stiffness and stability, improving the bearing capacity and bending resistance, optimizing the stress distribution, and improving the construction efficiency and safety. These functions together ensure the stability and reliability of the component in a complex stress environment.

[0007] Optionally, the pair of webs are arranged in parallel, the lengths of the pair of webs are different, and the lengths of the pair of webs are respectively greater than 700 mm.

[0008] By adopting the above technical solution, the design with different web lengths but both greater than 700 mm not only meets specific structural requirements but also improves the bearing capacity and stability of the component in the length direction by increasing the material usage in the length direction.

[0009] Optionally, the flange plate includes a main plate and auxiliary plates installed on both sides of the main plate. The main plate is trapezoidal, and the pair of auxiliary plates are rectangular. The lengths of the pair of auxiliary plates are twice the width of the main plate.

[0010] By adopting the above technical solutions, the design of the flange plate is an important measure to enhance the flexural capacity of the component. The trapezoidal design of the main plate helps to disperse stress, making the stress distribution more uniform when stressed, thereby improving the bearing capacity and stability of the component. As an extension of the main plate, the secondary plate not only increases the width of the flange plate but also further enhances the flexural capacity of the component.

[0011] Optionally, the stiffening plate and the partition are on the same horizontal plane. Grooves are respectively formed on the stiffening plate, the partition and the web, and the angle of the groove is 35°.

[0012] By adopting the above technical solutions, the design of the stiffening plate provides additional strength support for the component. Acting together with the partition, it further enhances the overall stiffness of the component. The stiffening plate and the partition being on the same horizontal plane ensures their close connection and collaborative work. The design of the groove is for facilitating welding and ensuring the weld quality. The 35° groove angle is an optimized choice, which can not only ensure the full fusion of the welding materials during welding but also reduce welding stress and deformation.

[0013] Optionally, a support plate is provided between a pair of the flange plates, and the support plate and the partition are on the same horizontal plane.

[0014] By adopting the above technical solutions, the design of the support plate provides additional support for the flange plate, enhancing the stability of the flange plate when stressed. The support plate and the partition being on the same horizontal plane ensures their collaborative work. This design helps to disperse the stress on the flange plate and prevent excessive deformation or damage of the flange plate when stressed.

[0015] Optionally, a backing plate is installed at one end of the flange plate and the web, and an arc-shaped groove is formed on the backing plate.

[0016] By adopting the above technical solutions, the design of the backing plate facilitates the hoisting and positioning of the component, improving the construction efficiency. The formation of the arc-shaped groove enables the backing plate to better cooperate with the hoisting equipment during hoisting, reducing friction and resistance during hoisting. At the same time, the backing plate also has a certain strength and stiffness, and can provide necessary support and protection for the component during hoisting.

[0017] Optionally, a lifting lug is installed on the flange plate.

[0018] By adopting the above technical solutions, the installation of the lifting lug is for facilitating the hoisting operation of the component. The design of the lifting lug should meet the strength and stability requirements during hoisting to ensure the safety and stability during hoisting.

[0019] Compared with the prior art, the beneficial effects of the present utility model are:

[0020] 1. By designing a structure with a partition plate set between a pair of webs, stiffening plates added on both sides of the partition plate, and flange plates installed on both sides of the webs, this sub-shaped main arch member can more effectively disperse and resist bending moments, shear forces, and torques from all directions, thus significantly improving the overall strength and stability of the member; 2. The design with different web lengths all greater than 700 mm and the combination form of the main plate and the sub-plate for the flange plates not only meets the requirements of structural strength but also avoids excessive waste of materials through reasonable size planning. This design concept reflects the careful calculation of material use and conforms to the concepts of green building and sustainable development; 3. The connection between the gusset plate and the stiffening plate and the support plate set between the flange plates enhance the connection strength and integrity between the various components of the structure, enabling the entire main arch member to maintain better cooperative working performance when stressed.

[0026] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the drawings in the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present utility model.

[0027] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "middle", "upper", "lower", "left", "right", "inside", "outside", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0028] AsFigure 1 As shown in Figure 4, the specific solution of the embodiment is as follows: A sub-shaped main arch member structure includes a pair of webs 1. The pair of webs 1 are arranged in parallel. The webs 1 are arc-shaped or straight-plate-shaped. The lengths of the pair of webs 1 are different, and the lengths of the pair of webs 1 are each greater than 700 mm. The design of the webs 1 helps to enhance the stability and load-bearing capacity of the member in the length direction. A partition 2 is provided between the pair of webs 1. The partition 2 is welded between the pair of webs 1. The partition 2 is arranged between the pair of webs 1, playing a role of separating and supporting, and enhancing the overall stiffness of the member. Stiffening plates 3 are provided on both sides of the partition 2. The stiffening plates 3 are located on both sides of the partition 2 and are on the same horizontal plane as the partition 2, providing additional strength support for the member;

[0029] Flange plates 4 are respectively installed on both sides of the web 1. The butt joint position of the flange plate 4 and the web 1 is a full penetration grade I. The flange plate 4 includes a main plate and auxiliary plates installed on both sides of the main plate. The main plate is trapezoidal. The main plate of the flange plate 4 is designed to be trapezoidal. This shape is beneficial to dispersing stress and improving the load-bearing capacity and stability of the member. The pair of auxiliary plates are rectangular, and the length of the pair of auxiliary plates is twice the width of the main plate. Such a design increases the width of the flange plate 4 and further enhances the bending resistance of the member. The welds between the flange plate 4, the web 1 and the stiffening plate are staggered by at least 300 mm. Weld concentration will lead to stress concentration in this area, increasing the risk when the structure is stressed. By staggering the welds, the influence of the welds on the structure can be dispersed, making the stress distribution more uniform, thereby improving the overall strength and stability of the structure. The stiffening plate 3 is on the same horizontal plane as the partition 2.

[0030] Grooves are respectively opened on the stiffening plate 3, the partition 2 and the web 1. The angle of the groove is 35°. The design of the groove is for easy welding and ensuring the weld quality. The groove is processed by a semi-automatic cutting machine. After processing, the groove surface and the range within 50 mm nearby need to be polished to remove sundries such as oxidation slag and oxide skin. A support plate 401 is provided between the pair of flange plates 4. The support plate 401 has the same function as the stiffening plate 3 and can provide additional support for the flange plate 4 to ensure the overall stability of the member. The support plate 401 is on the same horizontal plane as the partition 2;

[0031] A gusset plate 402 is installed at one end of the flange plate 4 and the web 1. The design of the gusset plate 402 facilitates the hoisting and positioning of components, improving construction efficiency. An arc-shaped groove is provided on the gusset plate 402, and a lifting lug 403 is installed on the flange plate 4. The weld of the lifting lug 403 is a full penetration grade III weld, ensuring a firm connection between the lifting lug 403 and the flange plate 4. During the hoisting process, operations should be carried out strictly in accordance with the hoisting plan to avoid safety accidents caused by overloading or improper operations. A node plate 5 is provided between a pair of the flange plates 4. The node plate 5 is connected to the stiffening plate 3. As a key connecting component, the node plate 5 ensures the close connection and coordinated operation between the various components of the component.

[0032] A pair of the webs 1 are arranged in parallel, and several partitions are provided between the pair of the webs 1. Two of the partitions are respectively located at the ends of the pair of the webs 1, and the remaining partitions are centrally installed at the middle position of the web 1. Stiffening plates are respectively installed on the upper and lower sides of the pair of the webs 1 and are in the same straight line as the partitions. The stiffening plates are divided into long stiffening plates and short stiffening plates. Short stiffening plates are respectively installed on the lower surfaces of the lower webs 1, and long stiffening plates and short stiffening plates are installed on the upper surfaces of the upper webs 1, and the short stiffening plates are located between the two long stiffening plates. Flange plates are respectively installed on the front and rear sides of the web 1. A node plate is installed at the position between the tops of the two flange plates. The lower end face of the node plate is connected to a plurality of long stiffening plates. The length of the node plate is the same as the upper end length of the flange plate.

[0033] The steel material of the main arch component is Q355B or Q390B-Z15, and the weld grade requirement of the main arch component is full penetration grade I or II, and 100% UT inspection is required. At the same time, the inspection requirements for the weld appearance are increased, such as there shall be no cracks, slag inclusions, lack of fusion and other defects on the weld surface. When cutting the main arch component, a straight-line cutting machine or a numerical control cutting machine shall be used, and specific cutting allowances and groove processing requirements shall be met. In the main arch component, regular plate parts are cut by a straight-line cutting machine, and irregular plate parts and parts are cut by a numerical control cutting machine. After the main arch component is welded, surface treatment shall be carried out before rust removal to remove burrs, welding slag, spatter, dust, oxide scale and coating materials until the metal luster of the steel surface is exposed;

[0034] When the plate thickness t ≤ 20mm, the weld requirement is a double-sided fillet weld. When the plate thickness t > 20mm, the weld requirement is partial penetration, and when the plate thickness t > 20mm, the fillet weld requirement is changed to a partial penetration weld, and the partial penetration requires a penetration depth of not less than 2t / 3 (t is the plate thickness). The additional fillet leg requirements for full penetration and partial penetration welds reach t / 4 and do not exceed 10mm.

[0035] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
