Description

Technical Field

[0001] The utility model relates to the field of accessories for engineering construction, and particularly relates to a shear stud shear-resistant structural member. Background Art

[0002] The steel-concrete composite structure utilizes the compressive performance of concrete and the tensile performance of steel to provide the maximum strength and stiffness with less materials, achieving efficient and lightweight design, and is widely used in the construction of scenarios such as power stations and airports. Shear studs are commonly used in the connection construction between steel structures and concrete; the acting area of the shear stud is relatively small. In the connection of long structures such as steel beams, multiple shear studs are often required to ensure the effect of surface connection through multi-point connection, so as to achieve reliable mechanical connection and mechanical transmission between the steel beam and the concrete. However, this also affects the construction efficiency. At the same time, when it is necessary to perform limiting or layout applications for pipes, etc., shear studs are generally not used. For example, at least in the open vertical direction, it is difficult for shear studs to conveniently achieve limiting applications. Therefore, it is necessary to provide a structural member for cooperating with the construction of shear studs. Content of the Utility Model

[0003] Aiming at the deficiencies in the prior art, the utility model provides a shear stud shear-resistant structural member to strengthen the mechanical connection strength between the steel beam and the concrete and improve the construction efficiency.

[0004] To achieve the above purpose, the utility model provides a shear stud shear-resistant structural member, which includes a body integrally formed by a strip-shaped metal member; the body includes a first horizontal section, a second horizontal section and a vertical section, wherein the first horizontal section and the second horizontal section are respectively connected to both ends of the vertical section and are located on different sides of the vertical section; the first horizontal section, the second horizontal section and the vertical section all include a groove structure with a U-shaped cross-section, and the side walls of the groove structures of the first horizontal section, the second horizontal section and the vertical section are continuously connected; the length of the first horizontal section is greater than the length of the second horizontal section, and at least one shear stud connection hole is provided at the bottom of the first horizontal section.

[0005] Further, a boss structure is stamped at the bottom of the groove structure of the vertical section.

[0006] Further, at least one through hole is provided at the bottom of the second horizontal section.

[0007] Further, when the number of the through holes is more than one, the minimum distance between adjacent through holes is not less than 8 millimeters.

[0008] Further, an electroplated layer is provided on the surface of the body.

[0009] Further, the length dimension of the first horizontal section is between 45 mm and 80 mm, the height dimension of the vertical section is between 75 mm and 160 mm, and the length dimension of the second horizontal section is between 15 mm and 30 mm; the width dimensions of the groove structures of the first horizontal section, the second horizontal section and the vertical section are between 20 mm and 60 mm.

[0010] Further, a second convex structure is stamped on the side wall of the groove structure at the joint of the first horizontal section and the vertical section to enhance the shear resistance.

[0011] Further, the side wall height of the groove structure near the joint of the first horizontal section and the vertical section is greater than the side wall height of the groove structure far from the joint of the first horizontal section and the vertical section; the minimum side wall height of the groove structures corresponding to the first horizontal section, the second horizontal section and the vertical section is not less than 5 mm.

[0012] Further, the thickness of the strip-shaped metal part is between 2 mm and 5 mm.

[0013] When using this structural member, the bottom surface of the first horizontal section of the structural member can be abutted against the steel structure, and the shear studs are passed through the shear stud connection holes of the first horizontal section of the structural member. The shear studs are passed through the steel structure and the concrete structure through the nail gun system, and the end of the larger head of the shear stud is pressed against the bottom surface of the groove of the first horizontal section of the structural member. After installing the shear studs, the first horizontal section of the structural member will be pressed against the steel structure in a surface contact manner, increasing the contact area and more effectively transmitting the mechanical connection force. The connection of two to three shear studs can enable the structural member to quickly establish a stable reference direction. When the first horizontal section is fixed, the side surface of the vertical section and the bottom surface of the second horizontal section can be used as limiting surfaces, and the contact area of the limiting surfaces is significantly increased compared with the contact area of the limiting studs. Under the same pressure, the resistance is better, and at the same time, the deformation of the contact surface of the pipe fitting is avoided, improving the reliability. Compared with the prior art, the utility model has the following beneficial effects: it can quickly form a stable three-dimensional limiting surface, which helps to improve the construction efficiency and has good reliability.

Detailed implementation mode

[0019] The technical solutions in the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] The present invention provides a shear stud shear-resistant structural member, as Figure 1 shown, including a body integrally formed by a strip-shaped metal member; the body includes a first horizontal section 101, a second horizontal section 103 and a vertical section 102, wherein the first horizontal section 101 and the second horizontal section 103 are respectively connected to both ends of the vertical section 102 and are located on different sides of the vertical section 102; the first horizontal section 101, the second horizontal section 103 and the vertical section 102 all include a U-shaped groove structure in cross-section, and the first horizontal section groove side wall 1061, the second horizontal section groove side wall 1063 and the vertical section groove side wall 1062 are continuously connected; through the integrally formed U-shaped groove structure, it is helpful to improve the shear resistance of the shear stud shear-resistant structural member, and the continuity of the groove structure side wall is helpful for the transmission of shear force, avoiding bending under force, thereby improving reliability. The length of the first horizontal section 101 is greater than the length of the second horizontal section 103, so that the first horizontal section 101 serves as the main working section for mechanical connection, ensuring its center of gravity balance. Even when the shear studs are not used, it can be placed independently and stably, which is convenient for use as a position reference for the side and horizontal planes. At least one shear stud connection hole is provided at the bottom of the first horizontal section 101. In this embodiment, three shear stud connection holes are provided. When the number of through holes is more than one, the minimum distance between adjacent through holes is not less than 8 mm. After installing the shear studs, the first horizontal section 101 of the structural member will be pressed against the steel structure in a surface contact manner, increasing the contact area of the contact surface, more effectively transmitting the mechanical connection force, and scientifically reducing the overall number of shear studs used during construction, which is helpful for improving the construction efficiency. As an embodiment, when it is necessary to reduce the contact surface in the vertical direction, as Figure 2 shown, a boss structure 1021 is stamped at the bottom of the groove structure of the vertical section. The boss structure 1021 reduces the limiting contact surface on the one hand and enhances the bearing capacity of the vertical section in the horizontal direction on the other hand. The thickness of the strip-shaped metal member is between 2 mm and 5 mm, and there is no welding or riveting on the structural member itself. The integrally formed structure ensures the force value requirement. When the structural member is in use, Figure 3 One of the usage scenarios is provided, Figure 3The connection between the first horizontal section 101 and the steel member is not shown in the figure, but the temporary limiting method of the vertical section 102 for the construction pipe fitting 2 is clear, that is, multiple structural members are relatively crossed on both sides of the construction pipe fitting 2. This construction method can also be applied to the profiled steel sheet with corrugations, thus preventing the deformation of the construction pipe fitting 2 or the corrugations.

[0021] In addition, at least one through hole 105 is provided at the bottom of the second horizontal section 103. In this embodiment, the number of through holes 105 is one. When the first horizontal section 101 is used as the main working section for mechanical connection and abuts against the surface of the steel member, for the steel member limited at a certain position below the second horizontal section 103, a bolt can pass through the through hole 105, with the head of the bolt facing the side close to the first horizontal section 101. The bolt passing through the through hole 105 is connected with a nut, and by adjusting the nut, the head of the bolt can be abutted against the surface of the steel member, thereby increasing its stability. For example, if the profiled steel sheet has multiple corrugations, combining this method to limit the corrugations can further improve the reliability of the construction. The through hole 105 can also serve a similar function as the shear stud connection hole 104. In a construction scenario with a similar step limit, the second horizontal section 103 can be used as the main working section, and the shear stud passes through the through hole 105, the steel member and the concrete structure, and the end of the larger head of the shear stud is pressed against the bottom surface of the groove of the second horizontal section 103 of the structural member.

[0022] The surface of the body is provided with an electroplated layer, and the electroplated layer is used to protect the body of the structural member from corrosion. Specifically, a galvanized layer is provided on the surface of the body in this embodiment.

[0023] The length dimension of the first horizontal section 101 is between 45 mm and 80 mm, the height dimension of the vertical section 102 is between 75 mm and 160 mm, and the length dimension of the second horizontal section 103 is between 15 mm and 30 mm; the width dimension of the groove structures of the first horizontal section 101, the second horizontal section 103 and the vertical section 102 is between 20 mm and 60 mm.

[0024] A second convex structure 1064 is stamped on the side wall of the groove structure at the joint of the first horizontal section 101 and the vertical section 102 to further enhance the shear resistance and prevent the angle between the first horizontal section 101 and the vertical section 102 from changing.

[0025] The side wall height of the groove structure near the joint of the first horizontal section 101 and the vertical section 102 is greater than the side wall height of the groove structure far from the joint of the first horizontal section 101 and the vertical section 102; the minimum side wall height of the groove structures corresponding to the first horizontal section 101, the second horizontal section 103 and the vertical section 102 is not less than 5 mm. Combining with the U-shaped groove structure, vertical temporary limiting of the sheet material can also be carried out, providing more choices for the construction environment.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
