Abstract
Description
Technical Field
[0001] The invention relates to the technical field of fixing steel plates, and in particular to a fastening bolt rivet component for preventing a thin plate steel structure from loosening and preventing interface side sliding. Background Art
[0002] Steel structure connection refers to the interconnection between steel structure members or components. Steel structure connection is widely used in buildings, bridges and other engineering fields, and its connection method is crucial to the performance and safety of the structure.
[0003] Traditional connection methods for thin-plate steel structures include welding, bolting and riveting. Among them, high-strength bolt connection is the most mainstream connection method, but when the bridge is subjected to vibration and load during use, the bolts are easy to loosen. Once a bolt is loose, the load on the adjacent bolts will increase, causing other bolts around it to start loosening. This phenomenon is called "loose propagation", which will aggravate the loosening problem and eventually cause the contact interface of the steel structure joint to slide, causing shear damage to the bolts. Welded steel structures are subject to thermal deformation and stress concentration. At the same time, the quality of the weld depends on the proficiency of the workers' skills. Operational errors may lead to poor quality of the welded joint, affecting the firmness of the connection and the safety of the structure. Riveting usually provides higher connection strength than bolting, especially for structures that need to withstand high loads, but due to the large size of the riveting equipment, it is difficult to construct in some local narrow spaces.

[0022] like Figure 1 As shown, the fastening bolt rivet component for preventing the thin plate steel structure from loosening and preventing the interface from sliding sideways is suitable for fixing the thin plate steel structure, and includes a bolt body 100, a fixing seat 140 and a load-bearing core bolt; the bolt body 100 is a hollow cylindrical structure with upper and lower openings, and is suitable for being inserted into a through hole on the thin plate steel structure 300 to be fixed; the fixing seat 140 is arranged at one end of the bolt body 100, and extends outwardly with a preset width relative to the circumference of the bolt body 100, and the middle part of the fixing seat 140 is also a hollow structure, which is connected to the bolt body 100. The hollow structure is connected; a fixing portion extending toward the outside of the circumference of the bolt body 100 is provided on the bolt body 100, the fixing portion abuts against one side of the thin steel plate structure 300 to be fixed, and the fixing seat 140 abuts against the other side of the thin steel plate structure 300 to be fixed; the load-bearing core bolt is arranged inside the bolt body 100 and the fixing seat 140; the fixing portion is formed by heating the bolt body 100 to enhance its plasticity after the bolt body 100 is inserted into the through hole, and then applying a riveting force along the axial direction of the bolt body 100 toward the fixing seat 140.
[0023] Specifically, the fixing seat 140 is provided to play a certain supporting role, supporting the bolt body 100. The fixing seat 140 is provided at one end of the bolt body 100, and extends outwardly by a preset width relative to the circumference of the bolt body 100, so that the diameter of the fixing seat 140 is larger than the diameter of the bolt body 100. The fixing seat 140 and the bolt body 100 are an integrated structure, and in order to be able to place the bolt, the bolt body 100 and the fixing seat 140 are hollow structures, and the bolt body 100 and the fixing seat 140 are connected. The fixing seat 140 also provides a reverse force arm during the riveting process. The fixing seat 140 is provided as a plate-like structure with a certain thickness, because sometimes the number of thin steel plate structures is large or the thickness of the thin steel plate structure is thick, and the fixing seat 140 has a certain thickness to avoid the fixing seat 140 bearing the load during the process of fixing the thin steel plate structure. In the event of failure to withstand pressure and breakage, the bolt body 100 is a hollow cylindrical structure with a certain length. The bolt body 100 is arranged on the top of the fixing seat 140. The bolt body 100 has a certain length because, in practice, the number of thin steel plate structures may be large and the thin steel plate structure also has a certain thickness. The bolt body 100 has a certain length in order to be able to pass through the thin steel plate structure. The bolt body 100 includes a deformation zone 110. After being heated and pressurized, the deformation zone 100 forms a fixing portion. The inner side of the fixing portion is tightly attached to the thin steel plate structure 300. The fixing portion cooperates with the fixing seat 140 to fix the thin steel plate structure 300. A load-bearing core bolt is arranged inside the bolt body 100 and the fixing seat 140 in order to stabilize and strengthen the tensile and shear resistance of the bolt body, thereby further strengthening the fixing performance.
[0024] In a possible implementation, the bolt body 100 further includes a force application area 120 and an expansion area 130 , and the force application area 120 , the deformation area 110 , and the expansion area 130 are sequentially connected from top to bottom.
[0025] Specifically, the bolt body is divided into a force application zone 120, a folding deformation zone 110 and an expansion zone 130. The force application zone 120 is used to apply pressure to the folding deformation zone 110 and the expansion zone 130. The folding deformation zone 110 begins to be squeezed and deformed after being subjected to pressure, and the expansion zone 130 begins to expand toward the outer peripheral side to support the thin steel plate structure after being subjected to pressure. In order to prevent the force application zone 120 from deforming when subjected to pressure, the inner diameter of the force application zone 120 is smaller than the inner diameter of the folding deformation zone 110. This arrangement makes the outer wall thickness of the force application zone 120 thicker and will not deform after being subjected to pressure. The outer wall thickness of the folding deformation zone 110 and the expansion zone 130 is thinner and is prone to deformation. The outer diameter and the inner diameter need to be compared with the commonly used series of bolts by calculating the tensile strength and shear strength, and finally determined after the performance is not less than the commonly used series of bolts used in actual working conditions.
[0026] In one possible implementation, the diameter of the force application zone 110 and the diameter of the expansion zone 130 are slightly smaller than the diameter of the through hole, and the expansion zone 130 is tightly connected to the inner circumference of the through hole after being subjected to pressure; the diameter of the fixing part is larger than the diameter of the through hole, and the diameter of the fixing part is larger than the diameter of the through hole, and the fixing part is formed by heating the deformation zone 110 to enhance its plasticity and then applying a riveting force.
[0027] Specifically, Figure 1 As shown, initially, the diameters of the force application zone 110, the expansion zone 130 and the deformation zone 110 are slightly smaller than the diameter of the through hole, so that the bolt body 100 can pass through the through hole. After local heating of the expansion zone 130 and the deformation zone 110, a riveting force is applied to form a fixing portion in the deformation zone 110. The diameter of the fixing portion is larger than the diameter of the through hole, so that the fixing portion cannot pass through the through hole.
[0028] In a possible implementation, the bolt body 100 is first recessed inward at a side of the fixing portion facing the fixing seat 140 , and then outwardly abuts against the inner side of the thin steel plate structure 300 to be fixed.
[0029] Specifically, Figure 1 As shown, the bolt body 100 is first passed through the through hole of the thin steel plate structure 300, and the plasticity of the deformation zone is enhanced by heating and a riveting force is applied to form a fixing portion. When pressure is applied, the portion of the bolt body 100 in the through hole will also be subjected to pressure, and thus will also deform to a certain extent. Because it is inside the through hole, the portion of the bolt body 100 in the through hole is tightly fitted with the inner wall of the through hole, forming an interference fit.
[0030] In a possible implementation, the load-bearing core bolt includes a load-bearing core bolt body and a load-bearing base 200, the load-bearing core bolt body is arranged on the top of the load-bearing base 200, and is an integrated structure, and its shape is the same as the hollow structure of the bolt body 100 and the hollow structure of the fixing seat 140; the load-bearing core bolt body includes a threaded area 210 and a load-bearing area 220, the load-bearing area 220 is arranged on the top of the load-bearing base 200, the threaded area 210 is arranged on the top of the load-bearing area 220, and an external thread is arranged on the threaded area 210; a chamfer 221 is arranged on the top of the load-bearing area 220, and the chamfer 221 is arranged around the top of the load-bearing area 220; an internal thread matching the external thread is arranged on the inner circumferential side of the force application area 120, the tooth shape of the internal thread is the same as the tooth shape of the external thread, and the pitch and number of thread heads of the internal thread are the same as the pitch and number of thread heads of the external thread.
[0031] Specifically, Figure 1As shown, the overall structure of the load-bearing core bolt is the same as the hollow structure of the bolt body 100 and the hollow structure of the fixing seat 140. The load-bearing core bolt includes a load-bearing core bolt body and a load-bearing base 200. The load-bearing core bolt body is arranged at the top of the load-bearing base 200, the load-bearing core bolt body is arranged inside the bolt body 100, and the load-bearing base 200 is arranged inside the fixing seat 140. In order to make the load-bearing core bolt better combined with the bolt body 100, the load-bearing core bolt body includes a threaded area 210 and a load-bearing area 220. The threaded area 210 is arranged at the top of the load-bearing area 220, and the threaded area 210 is provided with an external thread; the inner circumferential side of the force application area 120 is provided with an internal thread matching the external thread, because the internal thread and the external thread must be used in conjunction with each other, because the tooth shape of the internal thread is required to be the same as the tooth shape of the external thread, and the pitch and number of thread heads of the internal thread are the same as the pitch and number of thread heads of the external thread; because when bending occurs to form a fixed portion, in order to better form the fixed portion,
[0032] In a possible implementation, a first annular groove 111, a second annular groove 112 and a third annular groove 113 are provided on the deformation zone 110 to facilitate the formation of a fixing portion; the first annular groove 111 is provided at the top of the deformation zone 110, the third annular groove 113 is provided at the bottom of the deformation zone 110, and the first annular groove 111 and the third annular groove 113 are provided on the outer peripheral side of the deformation zone 110; the second annular groove 112 is provided on the inner peripheral side of the deformation zone 110, and is located between the first annular groove 111 and the third annular groove 113; the third annular groove 113 is connected to the thin steel plate structure 300.
[0033] Specifically, Figure 1 As shown, in order to better form the fixing part, a first annular groove 111 is provided at the top of the deformer 110, and a third annular groove 113 is provided at the bottom of the deformation zone 110. Because the formed fixing part needs to fix the thin steel plate structure 300, the fixing part needs to contact the thin steel plate structure 300. The third annular groove 113 is provided at the bottom of the deformation zone 110 and contacts the thin steel plate structure 300. The first annular groove 111 and the third annular groove 113 are provided to make the position of the first annular groove 111 and the outer wall of the third annular groove 113 thinner, so that the deformation zone is easily deformed after heating to enhance its plasticity and applying a riveting force; in order to prevent the fixing part from being recessed into the interior of the bolt body 100, a second annular groove 112 is provided on the inner peripheral side of the deformation zone 110 and located between the first annular groove 111 and the third annular groove 113. At the same time, the load-bearing core bolt is provided in the bolt body 100 and the fixing seat 140, which also prevents the fixing part from being recessed into the interior of the bolt body 100.
[0034] In a possible implementation, a processing groove 131 is provided at the bottom of the bolt body 100 to facilitate snapping onto the edge of the through hole.
[0035] Specifically, Figure 1As shown, because a through hole is opened on the thin steel plate structure 300, a corner is formed. In order to enable the fixing seat 140 to better fit with the thin steel plate structure 300, a processing groove 131 is provided at the bottom of the bolt body 100, which is also the connection position between the bolt body 100 and the fixing seat 140, so that the bolt body 100 can better enter the through hole and the fixing seat 140 can better fit with the thin steel plate structure 300, so as to better cooperate with the fixing part to fix the thin steel plate structure 300.
[0036] In one possible implementation, the shape of the outer periphery of the fixing seat 140 is hexagonal, square or cylindrical; the shape of the outer periphery of the load-bearing base 200 matches the shape of the fixing seat 140, which is hexagonal, square or cylindrical; the bolt body 100 and the fixing seat 140 are integrally formed.
[0037] Specifically, Figure 1 As shown, according to the actual needs and customer demands, the shape of the outer circumference of the fixing seat 140 is set to be hexagonal, square or cylindrical, because the load-bearing core bolt must be set in the bolt body 100 and the fixing seat 140, and because the shape of the outer circumference of the load-bearing base 200 must be the same as the shape of the outer circumference of the fixing seat 140 in order to be used together.
[0038] The fixing seat 140 and the bolt body 100 may be made of alloy steel, carbon steel, aluminum alloy, copper, titanium alloy, etc. according to actual needs.
[0039] When the present application is used: a through hole is punched at the same position on the thin steel plate structure 300 that needs to be fixed together, and then the bolt body 100 is heated, and the bolt body 100 passes through the through hole, and the fixing seat 140 is on one side of the thin steel plate structure 300. After heating, a riveting force is applied to the force application area 120, and through the heated bolt body 100, the folded deformation area 110 begins to protrude toward the outer peripheral side, and finally a fixed part is formed, and one side of the fixed part is connected to the thin steel plate structure 300. After applying the riveting force, the expansion area 130 also begins to expand toward the outer peripheral side to fill the gap of the through hole of the thin steel plate structure, and finally the deformed fixing part cooperates with the fixing seat 140 to fix the thin steel plate structure 300.
[0040] The present application provides a fixing seat 140 and a bolt body 100 to reduce the overall volume. The fixing seat 140 plays a certain supporting role, supporting the bolt body 100, and the fixing seat 140 also provides a reverse force arm during the riveting process. The load-bearing core bolts are provided inside the bolt body 100 and the fixing seat 140 to stabilize and strengthen the tensile and shear resistance of the bolt body, further strengthening the fixing performance. The first annular groove 111, the second annular groove 112 and the third annular groove 113 are provided on the deformation zone 110 to facilitate the formation of a fixing portion. The bottom of the bolt body 100 is provided with a processing groove 131 to facilitate the clamping of the edge of the through hole. Through the above arrangement, the present application fixes the thin steel plate structure to be fixed by the cooperation between the formed fixing portion and the fixing seat 140, thereby achieving the effect of tightening and preventing loosening, and solving the technical problems of complex riveted parts structure and poor fixing effect.
[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and concepts of the present invention within the scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
