Description

Technical Field

[0001] The utility model relates to the technical field of top nodes of steel structure corridor brackets, in particular to a novel top method of a closed corridor bracket. Background Art

[0002] At present, in order to ensure that the corridor, its supports and adjacent buildings (structures) can form a complete longitudinal stability system and earthquake-resistant system, fixed supports are usually required. For long-distance belt conveyors, fixed support columns and lateral supports are generally made of hot-rolled H-shaped steel or rectangular and round tubes. When the height of the support is less than 15m, a structure with equal widths at the top and bottom is usually adopted. When the height of the support is greater than 15m, a trapezoidal structure with a small top and a large bottom is usually adopted.

[0003] When the length of each span of the belt conveyor and the height of the fixed bracket are large, the corridor often has a large head / tail wheel load, and the bracket bears a large load. When the height of the corridor bracket is greater than 25m, the wind vibration effect is obvious. The corridor span is large, and the bracket bears a large wind load. At the same time, when the earthquake intensity is large, the seismic force borne by the corridor fixed bracket is very large, causing a sharp increase in the amount of steel used in the bracket. In order to ensure the continuity of the corridor, the head or tail of one side of the corridor usually needs to be cantilevered a certain length according to the size of the fixed bracket, resulting in the problem of eccentricity of the foundation, affecting the size of the foundation and increasing the amount of engineering work for the foundation. Utility Model Content

[0004] In order to improve the above-mentioned problems, the utility model provides a novel top method of a closed corridor bracket.

[0005] The utility model provides a novel top construction method of a closed corridor support, which adopts the following technical scheme: a novel top construction method of a closed corridor support, two groups of transverse beams and two groups of longitudinal beams are respectively arranged at a certain distance from the top of a fixed support and at the same horizontal front, rear, left and right sides, the upper parts of the two ends of the two groups of transverse beams parallel to the running direction of the belt conveyor are respectively connected with inclined oblique columns, the tops of the two groups of oblique columns are connected to shoulder beams, and the two ends of the two groups of longitudinal beams perpendicular to the running direction of the belt conveyor are also respectively connected with inclined oblique columns and column supports at the upper parts, the connection between the oblique columns and the shoulder beams is realized by cantilever beam sections and cantilever column sections, and the flanges of the cantilever beam sections are vertical bars at the ends of steel structure corridors;

[0006] The width of the upper flange plate of the cantilever beam section gradually narrows, and the upper flange end at the intersection of the cantilever beam section and the column is locally widened according to the size and position of the vertical rod at the end of the corridor. The cantilever beam section and the shoulder beam flange are fully welded (with an arc-starting plate), and the web is connected with friction-type high-strength bolts. The inclined column is connected to the shoulder beam through the cantilever column section, and the cantilever beam part of the inclined column and the flange and web of the inclined column are connected with a full-penetration groove weld.

[0007] Based on the above technical features: This scheme forms a basic frame structure at the top of the bracket by setting up two groups of transverse beams and two groups of longitudinal beams, and oblique columns are obliquely connected at both ends of the two groups of transverse beams and the two groups of longitudinal beams, and the top of the oblique columns is connected to the shoulder beam. The basic frame structure of the top of the bracket is formed, and the oblique columns and the shoulder beams are connected by cantilevered beam sections and cantilevered column sections, so that the shoulder beam can cantilever support the end of the corridor to achieve a closing transition. The corridor end vertical bars are set on the cantilevered beam sections, and the corridor end vertical bars are fully welded to the shoulder beams, so that the ends have strong rigidity and bearing capacity. From the above, it can be seen that this scheme improves the overall rigidity and stability by optimizing the dimensions and connection methods of components such as cantilevered beam sections, cantilevered column sections, oblique columns, transverse beams and longitudinal beams.

[0009] Based on the above technical features: This solution helps to form a stable, coordinated and reliable structure on the top of the bracket through the setting of vertical support structure and the application of connecting plates, as well as the use of double-sided fillet weld connection, which meets the stability and reliability requirements of the corridor bracket during operation and load bearing.

[0010] As a new type of top method of a closed corridor support described in the utility model, the corridor end vertical bars at both ends of the top of the cantilever beam section are symmetrically placed, and the welding connection between the transverse beam and the inclined column is transitioned through an arc.

[0011] Based on the above technical features: This solution plays an important role in the design of the corridor end part through the symmetrically placed corridor end vertical rods and the welding connection method through arc transition, which helps to improve the overall stability, rigidity and appearance of the bracket, which has a positive impact on the normal operation and safety of the belt conveyor bracket.

[0014] As a new type of top method of a closed corridor support described in the utility model, the thickness of the upper flange connecting the cantilever beam section and the vertical rod at the end of the corridor is not less than 25 mm.

[0015] Based on the above technical features: The thickness of the upper flange in this solution is directly related to the strength of the connection between the cantilever beam section and the vertical rod at the end of the corridor. By setting the upper flange thickness to be not less than 25mm, the bearing capacity of the connection point can be effectively improved, and the overall strength of the structure can be increased, so that the bracket can better withstand the force from the upper load.

[0016] As a new type of top method of a closed corridor support described in the utility model, the shoulder beam and the inclined column are both made of H-shaped steel, and the inter-column support is made of square steel pipes or round steel pipes.

[0017] Based on the above technical features: the shoulder beam and the diagonal column in this scheme are both made of H-shaped steel, which has high strength and rigidity and is suitable for structures that bear large loads. In the bracket, the shoulder beam and the diagonal column are the main load-bearing components, and the use of H-shaped steel helps to ensure that the entire bracket has sufficient strength and stability;

[0018] The inter-column supports in this scheme adopt square steel tubes or round steel tubes. Compared with solid steel columns, square steel tubes or round steel tubes are relatively light in weight, which is conducive to lightweight design, reducing the weight of the bracket itself, and reducing the load on the foundation. Square steel tubes or round steel tubes have regular cross-sections and are easy to process and connect, which is conducive to the manufacture and installation of the bracket and improves the construction efficiency of the project. Square steel tubes or round steel tubes as supporting components have good bending strength, can effectively support the corridor structure, and enhance the overall stability of the bracket.

The upper parts of the two ends of the two groups of horizontal beams 4 parallel to the running direction of the belt conveyor are respectively connected with inclined oblique columns 6. The tops of the two groups of oblique columns 6 are connected to the shoulder beam 1. The two ends of the two groups of longitudinal beams 8 perpendicular to the running direction of the belt conveyor are also respectively connected with inclined oblique columns 6 and column supports 3 at the upper parts. The connection between the oblique columns 6 and the shoulder beam 1 is through The cantilever beam section 2 and the cantilever column section 5 are realized, the flange of the cantilever beam section 2 is the steel structure corridor end vertical rod 7, the width of the upper flange plate of the cantilever beam section 2 is gradually narrowed, and the upper flange end at the intersection of the cantilever beam section 2 and the column is locally widened according to the size and position of the corridor end vertical rod 7, the cantilever beam section 2 and the shoulder beam 1 flange are fully welded (with an arc-starting plate), the web friction type high-strength bolts are connected, the inclined column 6 is connected to the shoulder beam 1 through the cantilever column section 5, and the cantilever beam part of the inclined column 6 and the flange and web of the inclined column 6 are connected with a full penetration groove weld.

[0028] An inter-column support 3 is arranged on the top of the bracket perpendicular to the running direction of the belt conveyor, and the inter-column support 3 and the inclined column 6 are connected by a connecting plate, and the connection between the connecting plate and the inter-column support 3 and the inclined column 6 is connected by a double-sided fillet weld, the inter-column support 3 and the shoulder beam 1 are connected by a connecting plate, and the connecting plate and the shoulder beam 1 and the inter-column support 3 are connected by a double-sided fillet weld. This scheme helps to form a stable, coordinated and reliable structure on the top of the bracket through the setting of a vertical support structure and the application of a connecting plate, as well as the use of a double-sided fillet weld connection method, which meets the stability and reliability requirements of the corridor bracket during operation and load bearing. The corridor end vertical rods 7 at both ends of the top of the cantilever beam section 2 are symmetrically placed, and the welding connection between the transverse beam 4 and the inclined column 6 is transitioned by an arc. The symmetrically placed corridor end vertical rods 7 and the welding connection method through the arc transition play an important role in the design of the corridor end part, which helps to improve the overall stability, rigidity and aesthetic appearance of the bracket, which has a positive impact on the normal operation and safety of the belt conveyor bracket.

[0029] See also Figure 2-4When the oblique column 6 and the shoulder beam 1 are connected, stiffening ribs are arranged at the corresponding positions. The thickness of the stiffening ribs should not be less than the corresponding flange thickness. The steel grade of the stiffening ribs is consistent with the corresponding components. By adding stiffening ribs at the connection between the oblique column 6 and the shoulder beam 1, the scheme fully takes into account the strength and stability at the connection point, provides more reliable support for the entire structure under stress conditions, and improves the overall performance and service life of the bracket.

Compared with solid steel columns, square steel tube or round steel tube is relatively light, which is conducive to lightweight design, reducing the weight of the bracket itself, and reducing the load on the foundation. Square steel tube or round steel tube has a regular cross-section and is easy to process and connect, which is conducive to the manufacture and installation of the bracket and improves the construction efficiency of the project. Square steel tube or round steel tube as a supporting member has good bending strength, can effectively support the corridor structure, and enhance the overall stability of the bracket.

It can be seen from the above that this scheme improves the overall rigidity and stability by optimizing the size and connection method of the cantilever beam section 2, the cantilever column section 5, the oblique column 6, the transverse beam 4 and the longitudinal beam 8.

[0032] This solution uses a new type of steel structure corridor support to significantly reduce the amount of steel structure used in the structure, reduce economic costs, and at the same time reduce the eccentricity effect, so that the force on the inclined column 6 is more reasonable, and the force on the foundation is more uniform, which increases the stability of the support. Especially for large-span corridors and ultra-high steel structure supports, the inclined column 6 and the foundation size are effectively optimized, and the installation is convenient, the number of nodes is reduced, and the construction efficiency is improved.
