Description

Technical Field

[0001] The present invention relates to the technical field of building steel structures, and in particular to a crane beam support connection structure and a connection method. Background Art

[0002] In heavy industrial plants, the tonnage of cranes is increasing, resulting in the crane beam itself bearing an increasingly large load. At the same time, the longitudinal force transmitted at the crane beam support, including the crane braking force and other loads, is very large. How to effectively transmit this longitudinal force to the plant columns and inter-column supports is very important for the crane beam support connection method.

[0003] Existing crane beam support connection methods include: spring plate connection method or bolt connection method, which often cannot meet the above-mentioned force transmission requirements due to the low quality of steel and weld materials, or the small diameter of bolts.

[0004] Therefore, it is necessary to propose a crane beam support connection structure and a connection method to solve at least one of the above problems. Summary of the Invention

[0008] In a preferred embodiment, the four sides of the baffle are fixedly connected to the top plate of the column shoulder beam by means of circumferential welding.

[0009] In a preferred embodiment, the gap between the crane beam support plate and the slotted hole is between 1 mm and 2 mm.

[0010] In a preferred embodiment, the baffle is made of high-strength steel plate.

[0011] In a preferred embodiment, the thickness of the baffle is smaller than the thickness of the crane beam support plate, the width of the baffle is larger than the width of the crane beam support plate, the baffle has a lower surface facing the column shoulder beam top plate, a transition step is formed between the lower surface of the baffle and the side wall of the column shoulder beam top plate, and a welding portion is provided at the transition step.

[0012] In a preferred embodiment, along the width direction, the baffle extends beyond the crane beam support plate by 100 mm to 200 mm on each side.

[0013] In a preferred embodiment, the crane beam is composed of at least two segmented crane beams, and for the column shoulder beam supported in the middle of a single crane beam, the slotted hole is configured to conform to the cross-sectional profile of a crane beam support plate.

[0014] In a preferred embodiment, the crane beam is composed of at least two segmented crane beams. For the column shoulder beam supported on the edge of a single crane beam, the structure of the slotted hole is configured to imitate the cross-sectional profile of the two crane beam support plates after splicing.

[0015] A crane beam support connection method is applied between a crane beam and a column shoulder beam, wherein a column shoulder beam top plate is provided on the top of the column shoulder beam, the crane beam comprises a crane beam body, and a crane beam support plate is provided on the crane beam body, which partially protrudes downward from the crane beam body. The crane beam support connection method comprises:

[0016] A slotted hole with a predetermined size is provided in the middle of a baffle with a predetermined thickness, wherein the slotted hole is used to insert the beam support plate, and the beam support plate is clearance-matched with the slotted hole;

[0017] Placing the baffle on the top surface of the column shoulder beam top plate, inserting the beam support plate into the slotted hole, and temporarily fixing the beam support plate and the baffle;

[0018] The outer periphery of the baffle is welded to the top plate of the column shoulder beam, and the inner side of the slotted hole and the crane beam support plate are not welded, and the beam support plate and the baffle are temporarily fixed.

[0019] In a preferred embodiment, the crane beam is composed of at least two segmented crane beams, and for the column shoulder beam supported on the edge of a single crane beam, the slotted hole is configured to conform to the cross-sectional profile of a crane beam support plate.

[0020] In a preferred embodiment, the crane beam is composed of at least two segmented crane beams. For the column shoulder beam supported in the middle of a single crane beam, the structure of the slotted hole is configured to imitate the cross-sectional profile of the two crane beam support plates after splicing.

[0021] The technical solution of the present invention has the following significant beneficial effects:

[0022] In the implementation mode of the present application, a slotted hole is provided in the middle of the baffle to clamp the crane beam support, thereby forming a baffle-type connection method. Specifically, the force transmission path is described as follows: the horizontal force borne by the crane beam is transmitted to the crane beam support through the crane beam component itself, and is transmitted to the support plate itself through the support plate weld; the two side surfaces of the crane beam support plate are in contact with the inner side of the slotted hole of the baffle, and the horizontal force is transmitted to the baffle through the pressure of this contact surface; the baffle is fixedly connected to the top plate of the column shoulder beam (welded with fillet welds) to transmit the horizontal force to the column shoulder beam, which can solve the problem of transmitting particularly large horizontal forces at the crane beam support.

[0023] The rationality of the force of the crane beam support connection structure provided in the embodiment of the present application is reflected as follows:

[0024] 1. The crane beam force is transmitted to the crane beam support plate by a fixed connection (such as a weld), which transmits the force directly and ensures the processing quality. However, the existing connection method, such as the spring plate connection method, is to connect the slot-shaped holes on the lower flange of the crane beam with the spring plate with bolts. In actual projects, since the spring plate is often not tightly fitted with the crane beam flange plate, the bolts are misaligned and easily damaged, resulting in little force bearing capacity. In addition, drilling holes on the crane beam itself also weakens the crane beam.

[0025] 2. The force transmission between the crane beam support and the baffle is more effective through end face pressure bearing. The design value of the end face pressure bearing strength of ordinary steel is 1.3-1.5 times the actual value of tensile strength.

The terms used herein in the specification of this application are intended only to describe specific embodiments and are not intended to limit this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0045] Existing technology 1: The crane beam support is supported on the column shoulder beam or the top surface of the bracket, and the lower flange of the crane beam and the column shoulder beam or the top surface of the bracket are connected by a spring plate. The above connection method has the following problems:

[0046] 1. The material of the spring plate connecting plate and the weld is low, and the bearing capacity is small;

[0047] 2. The spring plate needs to be welded on-site with the lower flange of the crane beam and the column shoulder beam or the top surface of the corbel. The construction space is small and the on-site welding is difficult; and the weld is prone to fatigue damage.

[0048] Existing technology 2: The crane beam support is supported on the column shoulder beam or the top surface of the bracket, and the lower flange of the crane beam and the column shoulder beam or the top surface of the bracket are connected by bolts. The above connection method has the following problems:

[0049] The bolt diameter is small and the load-bearing capacity is small. At the same time, there is generally a gap of 30-50mm between the lower flange of the crane beam and the column shoulder beam or the top surface of the corbel. The force on the bolt here is not pure shear, but also secondary bending moment. The force transmission is not direct and the load-bearing capacity is small.

[0050] The present invention provides a crane beam support connection structure and a connection method, which can solve the problem of large horizontal force transmitted longitudinally by the crane beam support connection; at the same time, the structure is simple, the force is reasonable, and the construction is convenient.

[0051] Please refer to the comprehensive Figures 1 to 6In the embodiment of the present application, a crane beam support connection structure is provided. The crane beam support connection structure is used to be arranged between the crane beam and the column shoulder beam 3. The top of the column shoulder beam 3 is provided with a column shoulder beam top plate 31. The crane beam includes a crane beam body 2. The crane beam body 2 is provided with a crane beam support plate 21 that partially protrudes downward from the crane beam body 2. The crane beam support connection structure includes: a baffle 1, and the baffle 1 is directly opposite to the crane beam support plate 21. A slotted hole 10 is provided at the position, the structure of the slotted hole 10 is adapted to the cross-section of the crane beam support plate 21, the crane beam support plate 21 is clearance-matched with the slotted hole 10, the four sides of the baffle plate 1 are fixedly connected to the column shoulder beam top plate 31, and the force on the crane beam is transmitted to the baffle plate 1 in a cross-sectional pressure-bearing manner through the crane beam support plate 21 and the inner side of the slotted hole 10 of the baffle plate 1, and then transmitted to the column shoulder beam top plate 31 through the baffle plate 1.

[0052] In the embodiment of the present application, a slotted hole 10 is provided in the middle of the baffle 1 to clamp the crane beam support, thereby forming a baffle 1 type connection mode. Specifically, the force transmission path is described as follows: the longitudinal horizontal force borne by the crane beam is transmitted to the crane beam support through the crane beam component itself, and is transmitted to the support plate itself through the support plate weld; the two side surfaces of the crane beam support plate 21 are in contact with the inner side of the slotted hole 10 of the baffle 1, and the horizontal force is transmitted to the baffle 1 through the pressure of this contact surface; the baffle 1 is fixedly connected to the column shoulder beam top plate 31 around the circle (welded with fillet welds) to transmit the horizontal force to the column shoulder beam 3, which can solve the problem of transmitting particularly large horizontal forces at the crane beam support.

[0053] The rationality of the force of the crane beam support connection structure provided in the embodiment of the present application is reflected as follows:

[0054] 1. The crane beam force is transmitted to the crane beam support plate 21 by a fixed connection (such as a weld), which directly transmits force and ensures processing quality. However, in existing connection methods, such as the spring plate connection method, the slotted holes on the lower flange of the crane beam are connected to the spring plate with bolts. In actual engineering, since the spring plate is often not tightly fitted with the crane beam flange plate, the bolts are misaligned and easily damaged, resulting in low load-bearing capacity. In addition, drilling holes in the crane beam itself weakens the crane beam.

[0055] 2. The force transmission between the crane beam support plate 21 and the baffle 1 is more effective through the end face pressure bearing. The design value of the end face pressure bearing strength of ordinary steel is 1.3-1.5 times the actual value of the tensile strength.

[0056] In one embodiment, the baffle 1 is fixedly connected to the column shoulder beam top plate 31 around its periphery by welding. When the baffle 1 is connected to the column shoulder beam top plate 31 by welding, since the welding position is on the outside of the baffle 1 and the column shoulder beam top plate 31, the operation space is large, the difficulty of on-site welding is low, and the structure of the column shoulder beam top plate 31 itself will not be damaged, and the force reliability is high. Of course, in some other ways, in theory, high-strength bolts can also be used to achieve connection. Relatively speaking, the use of the above-mentioned bolt connection will damage the structure of the column shoulder beam top plate 31 itself.

[0057] For example, the baffle 1 is welded around its perimeter to the column shoulder beam top plate 31. The baffle 1 has a lower surface facing the column shoulder beam top plate 31. A transition step is formed between the lower surface of the baffle 1 and the sidewall of the column shoulder beam top plate 31, and a welded portion is provided at the transition step. To form this transition step, the baffle 1 may extend beyond the column shoulder beam top plate 31 by a certain dimension, for example, 100 mm. Specifically, this application does not specify the specific value of this dimension.

[0058] When the welding portion is arranged at the above-mentioned transition step position, the following technical effects can be achieved:

[0059] The geometric shape of the transition step (e.g., a stepped shape) can change the stress transfer path, avoiding sharp right angles or sudden cross-section changes at the weld. This can reduce stress concentration at the weld, lower the risk of cracks in the structure under dynamic loads or alternating stresses, and extend the service life of the entire structure.

[0060] By performing welding at the above-mentioned transition step, it is convenient to accurately control the welding gun angle and welding parameters during welding, reduce welding defects caused by space limitations (such as incomplete penetration, slag inclusion, etc.), and improve weld formation quality and welding efficiency;

[0061] The transition step expands the connection surface between the baffle 1 and the column shoulder beam top plate 31 from a simple plane contact to a stepped multi-layer contact, thereby increasing the actual effective contact area of ​​the weld, improving the load-bearing capacity of the weld, and being able to withstand greater tensile, compressive and shear loads, thereby improving the reliability of the structural connection;

[0062] The step transition structure can guide the load to be gradually transferred along the multi-level interface, avoiding the load concentration on a single weld section. Therefore, when the structure is subjected to external load, the stress can be evenly distributed to the overall interface between the baffle 1 and the top plate through the transition step, reducing deformation or damage caused by local overload and enhancing the overall stability of the structure.

[0063] In one embodiment, the baffle 1 may be made of high-strength steel plates, thereby reliably ensuring the strength of the structure itself.

[0064] The baffle plate 1 has a predetermined thickness, which is less than the thickness of the crane beam support plate 21. For example, the baffle plate 1 is generally 10 mm thinner than the crane beam support plate 21. The thickness of the baffle plate 1 can be calculated based on existing theories, and this application does not impose a single numerical limit on its specific value.

[0065] The width of the baffle 1 is greater than the width of the crane beam support plate 21, thereby ensuring that the opening on the baffle 1 can completely cover the crane beam support plate 21. Specifically, along the width direction, each side of the baffle 1 exceeds the crane beam support plate by 100 mm to 200 mm.

[0066] In one embodiment, the gap between the crane beam support plate 21 and the slotted hole 10 is between 1 mm and 2 mm. When the crane beam support plate 21 and the slotted hole 10 are matched with a small gap, the crane beam support plate 21 can be easily displaced and accurately aligned with the side wall of the slotted hole 10 in a timely, reliable, and accurate manner when subjected to horizontal force, thereby achieving the transmission of horizontal force.

[0067] Please refer to Figure 1 、 Figure 2 and Figure 3 In a specific embodiment, the crane beam is composed of at least two segmented crane beams. For the column shoulder beam 3 supported on the edge of a single crane beam, the structure of the slotted hole 10 is configured to imitate the cross-sectional profile of one of the crane beam support plates 21.

[0068] In this embodiment, Figure 1 The method of supporting the crane beam with a high-strength steel baffle 1 at the column shoulder beam 3 (abbreviated as edge column) at the edge of a single crane beam is shown.

[0069] In this embodiment, the crane beam can be a continuous box-type crane beam, which has a box-beam structure enclosed by an upper flange plate, a lower flange plate, a first web plate, and a second web plate. For the side columns, the crane beam support is fixed with a crane beam support plate 21 at the bottom of the lower flange plate. Above this crane beam support plate 21, crane beam support stiffening ribs 22 can be installed at the corresponding web positions to enhance structural strength.

[0070] In the side column baffle 1, a crane beam support plate 21 needs to be inserted into its slotted hole 10. Therefore, the slotted hole 10 is configured to conform to the cross-sectional profile of the crane beam support plate 21. For example, if the cross-section of the crane beam support plate 21 is rectangular with a first length and a first width, the slotted hole 10 can be a rectangular hole with a long side length of 2-3 mm greater than the first length and a short side width of 2-3 mm greater than the first width.

[0071] Please refer to Figure 4 、 Figure 5 and Figure 6 In another specific embodiment, the crane beam is composed of at least two segmented crane beams. For the column shoulder beam 3 supported in the middle of a single crane beam, the structure of the slotted hole 10 is configured to imitate the cross-sectional profile of the two crane beam support plates 21 after splicing.

[0072] In this embodiment, Figure 4 The method of supporting a crane beam with a high-strength steel baffle 1 at a column shoulder beam 3 (referred to as a middle column) in the middle of a single crane beam is shown.

[0073] In this embodiment, the crane beam can be a continuous box-type crane beam, which has a box-shaped beam structure formed by an upper flange plate, a lower flange plate, a first web plate, and a second web plate. For the center column, a longitudinally extending crane beam support plate 21 is provided at the end of the crane beam in the height direction, with the lower end of the crane beam support plate 21 extending below the lower flange plate.

[0074] For the baffle plate 1 at the center column, two crane beam support plates 21 need to be inserted into its slotted hole 10. Therefore, the structure of the slotted hole 10 is configured to conform to the cross-sectional profile of the two crane beam support plates 21. Specifically, when manufacturing the slotted hole 10, in order to facilitate the processing of the slot, two halves can be first manufactured and then spliced ​​together to form a complete slotted hole 10.

[0075] For example, when the cross-section of the crane beam support plate 21 is a rectangle with a second length and a second width, the slotted hole 10 can be a rectangular hole, the length of its long side of which is 2-3 mm greater than the second length; the width of its short side of which is 2-3 mm greater than the first width plus the gap between the two crane beam support plates 21.

[0076] In an embodiment of the present application, a crane beam support connection method is further provided. The crane beam support connection method is applied between a crane beam and a column shoulder beam 3. A column shoulder beam top plate 31 is provided on the top of the column shoulder beam 3. The crane beam includes a crane beam body 2. A crane beam support plate 21 partially protruding downward from the crane beam body 2 is provided on the crane beam body 2. The crane beam support connection method includes:

[0077] A slotted hole 10 of predetermined size is provided in the middle of the baffle 1 of predetermined thickness, wherein the slotted hole 10 is used to insert the beam support plate, and the beam support plate is clearance-matched with the slotted hole 10;

[0078] Place the baffle 1 on the top surface of the column shoulder beam top plate 31, insert the beam support plate into the slotted hole 10, and temporarily fix the beam support plate and the baffle 1;

[0079] The outer periphery of the baffle 1 is welded to the column shoulder beam top plate 31 , while the inner side of the slotted hole 10 and the crane beam support plate 21 are not welded, and the beam support plate and the baffle 1 are temporarily released from fixation.

[0080] A crane beam support connection method is also provided in an embodiment of the present application. The crane beam support connection method is used to produce a crane beam support connection structure. Since the crane beam support connection structure can be obtained by the crane beam support connection method, the technical effect achieved by the crane beam support connection structure embodiment can be achieved. For details, please refer to the specific description of the above embodiment, and this application will not repeat it here.

[0081] Please refer to Figure 1 、 Figure 2 and Figure 3 In a specific embodiment, the crane beam is composed of at least two segmented crane beams. For the column shoulder beam 3 supported on the edge of a single crane beam, the structure of the slotted hole 10 is configured to imitate the cross-sectional profile of one of the crane beam support plates 21.

[0082] In this embodiment, Figure 1 The invention shows a method of supporting a crane beam with a high-strength steel baffle plate 1 at the shoulder beam 3 (referred to as the side column) at the edge of a single crane beam, wherein for the baffle plate 1 at the side column, a crane beam support plate 21 needs to be inserted into its slotted hole 10. Therefore, the structure of the slotted hole 10 is configured to imitate the cross-sectional profile of the crane beam support plate 21.

[0083] For example, when the cross-section of the crane beam support plate 21 is a rectangle with a first length and a first width, the slotted hole 10 can be a rectangular hole, the length of its long side is 2-3 mm greater than the first length; the width of its short side is 2-3 mm greater than the first width.

[0084] Please refer to Figure 4 、 Figure 5 and Figure 6 In another specific embodiment, the crane beam is composed of at least two segmented crane beams. For the column shoulder beam 3 supported in the middle of a single crane beam, the structure of the slotted hole 10 is configured to imitate the cross-sectional profile of the two crane beam support plates 21 after splicing.

[0085] In this embodiment, Figure 4The figure shows a crane beam support structure using a high-strength steel baffle plate 1 at the center of a single crane beam (referred to as the center column). The baffle plate 1 at the center column requires two crane beam support plates 21 to be inserted into its slotted hole 10. Therefore, the slotted hole 10 is configured to conform to the cross-sectional profile of the two crane beam support plates 21. Specifically, to facilitate slotting, the slotted hole 10 can be fabricated in two halves, which can then be spliced ​​together to form a complete slotted hole 10. This means the slotted hole 10 can be a spliced ​​hole.

[0086] For example, when the cross-section of the crane beam support plate 21 is a rectangle with a second length and a second width, the slotted hole 10 can be a rectangular hole, the length of its long side of which is 2-3 mm greater than the second length; the width of its short side of which is 2-3 mm greater than the first width plus the gap between the two crane beam support plates 21.

There is no order of precedence between the two, nor should they be understood to indicate or imply relative importance.
