Description

Technical Field

[0001] This utility model relates to the field of steel structure beam technology, specifically a novel steel structure beam. Background Technology

[0002] Steel structural beams are beams made primarily of steel and are crucial components in building structures used to support vertical loads. Through their high strength and excellent mechanical properties, steel structural beams effectively distribute the loads on buildings or bridges to columns or other supporting structures, thereby ensuring the stability and safety of the entire structure.

[0003] The existing patent document with authorization announcement number CN222044505U describes a novel steel structure beam connection structure, including a main mounting part. A trapezoidal protrusion is integrally formed on the center of one side of the main mounting part, and side mounting parts are integrally formed on both the front and rear sides of the trapezoidal protrusion. In this technical solution, a drainage hole connects to the trapezoidal protrusion. When leakage occurs and liquid flows down the column, the liquid flows into the groove and down along the drainage strip through the drainage hole, preventing the liquid from flowing between the steel structure beam and the side mounting parts and causing corrosion to the steel surface. However, under dynamic loads, fatigue cracks are prone to occur at the connection points between the drainage strips, affecting the stability of the structure. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a novel steel structure beam that solves the problem that fatigue cracks easily occur at the connection between the drainage strips under dynamic loads, affecting the stability of the structure. Furthermore, when the drainage base plate and drainage side plate are used for drainage, fatigue cracks easily occur at the connection between the drainage side plate and the drainage base plate under dynamic loads. The first reinforcing rib is used to improve the stress distribution at the connection, reduce the generation and propagation of fatigue cracks, and improve the fatigue resistance of the structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a novel steel structure beam, comprising an installation assembly, a drainage assembly, and a side plate assembly. The installation assembly includes a main installation plate, the drainage assembly includes a trapezoidal plate and a drainage base plate, and the side plate assembly includes an installation side plate and an installation layer plate. The main installation plate has a first installation hole penetrating its thickness on its inner side. The trapezoidal plate has a converging groove on its inner side of the top wall and a drainage hole on its inner side of the upper part. The drainage base plate is connected to the top of the drainage side plate, and a single-chamber groove is formed on its inner side. A first reinforcing rib is provided at the connection between the drainage base plate and the drainage side plate. A second reinforcing rib is connected to one end of the drainage base plate. The installation side plate has a second installation hole penetrating its thickness on its inner side. A corrugated steel plate is connected to the inner side of the installation layer plate, and a third reinforcing rib is connected to the bottom of the installation layer plate.

[0006] The beneficial effects of this utility model are as follows: When the drainage base plate and the drainage side plate are used for drainage, fatigue cracks are easily generated at the connection between the drainage side plate and the drainage base plate under dynamic load. The first reinforcing rib is used to improve the stress distribution at the connection, reduce the generation and propagation of fatigue cracks, and improve the fatigue resistance of the structure. The single-chamber groove with only one cavity inside the drainage base plate gives it good spatial stress performance and can effectively resist bending, torsion and shear forces. The drainage base plate with the single-chamber groove structure can effectively utilize materials while providing a large cross-sectional bending moment of inertia, thus improving the structural stability and economy.

[0007] For mounting the side panel via the second mounting hole:

[0008] As a further improvement to the above technical solution: the first mounting holes are symmetrically opened on the upper and lower sides of the trapezoidal plate, and the trapezoidal plate is connected to the main mounting plate along the width direction.

[0009] The beneficial effects of this improvement are: the first mounting hole is used to connect the main mounting plate to the predetermined mounting base surface, and the second mounting hole is used to install and connect the mounting side plate.

[0010] The purpose of the drainage channel is to collect rainwater flowing down from the main mounting plate and leaking from the joint between the main mounting plate and the intended mounting base, and to drain the rainwater away through the drainage channel:

[0011] As a further improvement to the above technical solution: the manifold is a concave groove, and the drainage hole is connected to the manifold.

[0012] The beneficial effects of this improvement are as follows: the drainage channel is used to collect rainwater flowing down from the main mounting plate and leaking from the joint between the main mounting plate and the predetermined mounting base, and the rainwater is drained away through the drainage channel, avoiding the accumulation and flow of rainwater on the surface of the trapezoidal plate, thereby reducing the erosion of the trapezoidal plate by rainwater, preventing the steel structure beam from rusting and corroding, and extending the service life of the steel structure beam. The drainage hole is used to guide rainwater out through a predetermined path, reducing the risk of rainwater seeping into the interior of the structure and achieving a waterproof and sealing effect.

[0013] The purpose of using the first stiffener is to improve stress distribution at the joint and reduce the initiation and propagation of fatigue cracks:

[0014] As a further improvement to the above technical solution: the side of the first reinforcing rib away from the drainage side plate is an arc-shaped structure, and the second reinforcing rib is set at equal intervals.

[0015] The beneficial effects of this improvement are as follows: When the drainage base plate and the drainage side plate are used for drainage, fatigue cracks are easily generated at the connection between the drainage side plate and the drainage base plate under dynamic load. The first reinforcing rib is used to improve the stress distribution at the connection, reduce the generation and propagation of fatigue cracks, and improve the fatigue resistance of the structure.

[0016] In order for the second reinforcing rib to distribute the concentrated stress over a larger area and reduce the stress peak at the connection:

[0017] As a further improvement to the above technical solution: there are two drainage base plates installed on the side of the trapezoidal plate where the drainage holes are opened. One drainage base plate is connected to the wall of the trapezoidal plate, and the other drainage base plate is connected to the wall of the mounting side plate. The ends of the two drainage base plates that are far apart are connected to a second reinforcing rib.

[0018] The beneficial effects of this improvement are as follows: Under load, stress concentration is prone to occur at the connection between the mounting side plate and the drainage base plate, as well as at the connection between the trapezoidal plate and the drainage base plate. The second reinforcing rib can disperse the concentrated stress to a larger area, reduce the stress peak at the connection, reduce the risk of structural damage caused by stress concentration, and extend the service life of the structure.

[0019] To ensure that the drainage base plate with a single-chamber groove structure provides a large cross-sectional bending moment of inertia while effectively utilizing materials and improving structural stability and economy:

[0020] As a further improvement to the above technical solution: the inner side of the drainage base plate is hollow, and the hollow cavity of the drainage base plate forms a single-chamber groove.

[0021] The beneficial effects of this improvement are as follows: the single-chamber groove with only one cavity inside the drainage base plate gives it good spatial stress performance, which can effectively resist bending, torsion and shear forces. The drainage base plate with the single-chamber groove structure can effectively utilize materials while providing a large cross-sectional bending moment of inertia, thus improving structural stability and economy.

[0022] The corrugated steel plates are designed to reduce the structure's self-weight, thereby lowering the foundation's load-bearing requirements.

[0023] As a further improvement to the above technical solution: the front cross-section of the corrugated steel plate is corrugated, and the mounting plate and the corrugated steel plate are integrally formed.

[0024] The beneficial effects of this improvement are as follows: By adopting a corrugated design, the corrugated steel plate reduces the self-weight of the structure, thereby reducing the load-bearing requirements of the foundation, reducing investment in foundation engineering, and also improving the safety of the structure under earthquake disasters.

[0025] To increase the effective cross-sectional area of ​​the connection points between the mounting shelves and the mounting side panels, so that the connection points between the mounting shelves and the mounting side panels can withstand greater loads:

[0026] As a further improvement to the above technical solution: there are two third reinforcing ribs, which are symmetrically installed at the bottom of the mounting plate. The side of the third reinforcing rib away from the mounting plate is connected to the mounting side plate. The third reinforcing rib is attached to the mounting side plate and connected to the trapezoidal plate.

[0027] The beneficial effects of this improvement are as follows: by setting the third reinforcing rib, the effective cross-sectional area of ​​the connection between the two ends of the mounting plate and the mounting side plate is increased, so that the connection between the mounting plate and the mounting side plate can withstand a greater load, improve the load-bearing capacity of the entire structure, and ensure that when subjected to a large external force, the stress amplitude and stress concentration coefficient at the connection are reduced by setting the third reinforcing rib, which can effectively extend the fatigue life of the structure and reduce structural failure and maintenance costs caused by fatigue damage.

The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0035] like Figure 1-5As shown, a novel steel structure beam includes an installation assembly 1, a drainage assembly 2, and a side plate assembly 3. The installation assembly 1 includes a main installation plate 11, the drainage assembly 2 includes a trapezoidal plate 21 and a drainage base plate 24, and the side plate assembly 3 includes a mounting side plate 31 and a mounting layer plate 33.

The top of the drainage base plate 24 is connected to a drainage side plate 25, and the inner side of the drainage base plate 24 has a single-chamber groove 26. The drainage base plate 24 and the drainage side plate 25 are connected to each other. A first reinforcing rib 27 is provided at the connection of the plate 25, a second reinforcing rib 28 is connected to one end of the drainage base plate 24, a second mounting hole 32 penetrating its thickness is opened on the inner side of the mounting side plate 31, a corrugated steel plate 34 is connected to the inner side of the mounting layer plate 33, a third reinforcing rib 35 is connected to the bottom of the mounting layer plate 33, the first mounting hole 12 is symmetrically opened on the upper and lower sides of the trapezoidal plate 21, and the trapezoidal plate 21 is connected to the main mounting plate 11 along the width direction; the first mounting hole 12 is used to connect the main mounting plate 11 to the predetermined mounting base surface, and the second mounting hole 32 is used to install and connect the mounting side plate 31. The drainage channel 22 is a concave channel, and the drainage hole 23 is connected to the drainage channel 22. The drainage channel 22 is used to collect rainwater flowing down from the main mounting plate 11 and leaking from the joint between the main mounting plate 11 and the predetermined mounting base surface, and drains the rainwater away through the drainage channel 22, preventing rainwater from accumulating and flowing on the surface of the trapezoidal plate 21, thereby reducing the erosion of the trapezoidal plate 21 by rainwater, preventing the steel structure beam from rusting and corroding, and extending the service life of the steel structure beam. The drainage hole 23 is used to guide rainwater out through a predetermined path, reducing the risk of rainwater seeping into the interior of the structure and achieving a waterproof sealing effect. The side of the first reinforcing rib 27 away from the drainage side plate 25 is an arc-shaped structure, and the second reinforcing rib 27 is an arc-shaped structure on the side away from the drainage side plate 25. The reinforcing ribs 28 are evenly spaced. When the drainage base plate 24 and the drainage side plate 25 are draining water, fatigue cracks are easily generated at the connection between the drainage side plate 25 and the drainage base plate 24 under dynamic load. The first reinforcing rib 27 is used to improve the stress distribution at the connection, reduce the generation and propagation of fatigue cracks, and improve the fatigue resistance of the structure. There are two drainage base plates 24, which are installed on the side of the trapezoidal plate 21 where the drainage hole 23 is opened. One drainage base plate 24 is connected to the wall of the trapezoidal plate 21, and the other drainage base plate 24 is connected to the wall of the mounting side plate 31. The ends of the two drainage base plates 24 that are far apart are connected to the second reinforcing rib 28.Under load, stress concentration is prone to occur at the connection between the mounting side plate 31 and the drainage base plate 24, as well as at the connection between the trapezoidal plate 21 and the drainage base plate 24. The second reinforcing rib 28 can disperse the concentrated stress over a larger area, reduce the stress peak at the connection, reduce the risk of structural damage caused by stress concentration, and extend the service life of the structure. The drainage base plate 24 is hollow inside, and the hollow cavity of the drainage base plate 24 forms a single-chamber groove 26. The single-chamber groove 26 inside the drainage base plate 24 provides good spatial stress performance and can effectively resist bending, torsion, and shear forces. The drainage base plate 24 with the single-chamber groove 26 structure provides a large cross-sectional bending moment of inertia while effectively utilizing materials, improving structural stability and economy. The front cross-section of the corrugated steel plate 34 is corrugated, and the mounting layer plate 33 and the corrugated steel plate 34 are integrally formed. The corrugated steel plate 34 adopts a corrugated shape. The third reinforcing rib 35 is designed to reduce the structure's self-weight, thereby lowering the foundation's load-bearing requirements and reducing foundation engineering investment. It also enhances the structure's safety under seismic loads. Two symmetrically arranged third reinforcing ribs 35 are installed at the bottom of the mounting plate 33. The side of the third reinforcing rib 35 furthest from the mounting plate 33 connects to the mounting side plate 31. The third reinforcing rib 35 is fitted along the mounting side plate 31 and connected to the trapezoidal plate 21. The third reinforcing rib 35 increases the effective cross-sectional area at the connection points between the mounting plate 33 and the mounting side plate 31, enabling the connection points to withstand greater loads and improving the overall structure's load-bearing capacity. This ensures that under significant external forces, the stress amplitude and stress concentration factor at the connection points are reduced, effectively extending the structure's fatigue life and reducing structural failures and maintenance costs due to fatigue damage.

[0036] The working principle of this utility model is as follows: the first mounting hole 12 is used to connect the main mounting plate 11 to the predetermined mounting base surface; the second mounting hole 32 is used to connect the mounting side plate 31; the corrugated steel plate 34 adopts a corrugated design to reduce the self-weight of the structure, thereby reducing the bearing requirements of the foundation, reducing the investment in foundation engineering, and also improving the safety of the structure under earthquake disasters; the third reinforcing rib 35 is used to increase the effective cross-sectional area of ​​the connection between the two ends of the mounting plate 33 and the mounting side plate 31, so that the mounting plate 33 and the mounting side plate 31 are connected. The connection point of the mounting side plate 31 can withstand greater loads, improving the overall load-bearing capacity of the structure. By setting the third reinforcing rib 35, the stress amplitude and stress concentration factor at the connection point are reduced when subjected to large external forces, effectively extending the fatigue life of the structure and reducing structural failures and maintenance costs caused by fatigue damage. The drainage channel 22 collects rainwater flowing down from the main mounting plate 11 and leaking from the joint between the main mounting plate 11 and the predetermined mounting base, and drains the rainwater away, preventing rainwater accumulation and flow on the surface of the trapezoidal plate 21, thereby reducing the impact of rainwater on the trapezoidal plate 21. Erosion prevention and rust control of steel structure beams extend their service life. Drainage holes 23 guide rainwater out along predetermined paths, reducing the risk of rainwater seeping into the structure and providing a waterproof seal. When the drainage base plate 24 and drainage side plate 25 are used for drainage, fatigue cracks are prone to occur at the connection between the drainage side plate 25 and the drainage base plate 24 under dynamic loads. The first reinforcing rib 27 is used to improve the stress distribution at the connection, reduce the generation and propagation of fatigue cracks, and improve the fatigue resistance of the structure. Under load, the connection between the mounting side plate 31 and the drainage base plate 24, as well as... The connection between the trapezoidal plate 21 and the drainage base plate 24 is prone to stress concentration. The second reinforcing rib 28 can disperse the concentrated stress to a larger area, reduce the stress peak at the connection, reduce the risk of structural damage caused by stress concentration, and extend the service life of the structure. The drainage base plate 24 has a single-chamber groove 26 with only one cavity inside, which gives it good spatial stress performance and can effectively resist bending, torsion and shear forces. The drainage base plate 24 with the single-chamber groove 26 structure can effectively utilize materials while providing a large cross-sectional bending moment of inertia, thus improving structural stability and economy.
