Technical Field

[0001] The utility model relates to the technical field of steel structure buildings, and particularly relates to a steel beam fixing device. Background Art

[0002] Steel structure connection refers to the mutual connection between steel structure components or parts. Weld connection, bolt connection or rivet connection are commonly used in steel structure connection. Bolt connection is further divided into ordinary bolt connection and high-strength bolt connection. Among them, the cross-sectional types of steel structures are diverse. As one of the most common cross-sections, H-shaped steel beams are widely used in infrastructure fields such as high-rise buildings, stadiums, and subway stations.

[0003] When assembling parts such as connecting plates and stiffening plates on H-shaped steel beams, they are usually placed on a jig beam at a certain height, which facilitates welding for workers. However, when the H-shaped steel beam is placed on the jig beam, it is in a free state. Without locking, there is a risk of tipping over and may hit the operator. Summary of the Utility Model

[0026] The technical solution of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0027] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0028] In the description of the present utility model, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0029] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0030] Such as Figure 1As shown in the figure, a steel beam fixing device provided by the utility model includes: a first fixing structure 1 and a second fixing structure 2, wherein the first fixing structure 1 is bent; a receiving space is formed between the bent portions of the first fixing structure 1; the receiving space is adapted to receive the flanges of two steel beams; wherein the second fixing structure 2 is fixedly connected to the first end of the first fixing structure 1; the second fixing structure 2 includes a fixing portion 21 and an adjusting portion 22; the fixing portion 21 is fixedly connected to the first end of the first fixing structure 1; the adjusting portion 22 is movably connected to the fixing portion 21, and the adjusting portion 22 is adapted to move towards the flange of the steel beam. In this solution, the flanges of the two steel beams are placed in the receiving space, and the flanges of the two steel beams are abutted by moving the adjusting portion 22. One side of the flanges of the two steel beams abuts against the adjusting portion 22, and the other side abuts against the inner wall of the receiving space, so as to lock the flanges of the two steel beams, thereby preventing the risk of overturning of the two steel beams and providing safety.

[0031] It should be noted that the H-shaped steel consists of two parallel flanges and a web; the H-shaped steel is divided into two types: hot-rolled H-shaped steel and welded H-shaped steel. The hot-rolled H-shaped steel is further divided into three types: wide flange H-shaped steel (HW), medium flange H-shaped steel (HM), and narrow flange H-shaped steel (HN). HW means that the height and flange width of the H-shaped steel are basically equal; it is mainly used for the steel core column in the reinforced concrete frame structure column, also known as the stiffened steel column; it is mainly used for columns in steel structures; HM means that the ratio of the height to the flange width of the H-shaped steel is approximately 1.33 to 1.75. It is mainly used in steel structures: as a steel frame column and as a frame beam in a frame structure bearing dynamic loads; for example: equipment platforms; HN means that the ratio of the height to the flange width of the H-shaped steel is greater than or equal to 2, and it is mainly used for beams; the use of I-beams is equivalent to that of HN-shaped steel; the main materials of H-shaped steel include Q235B, SM490, SS400, Q345, Q345B, etc.

[0032] It should be noted that in this embodiment, the first end of the first fixing structure 1 is the end close to the top, and the second end is the end close to the bottom.

[0033] It should be noted that in this embodiment, the fixing portion 21 is a nut; the adjusting portion 22 is a bolt. Specifically, the specification of the nut of the fixing portion 21 is M30; in the actual operation process, the distance between the adjusting portion 22 and the flange of the steel beam is adjusted by rotating the adjusting portion 22. In this embodiment, the flanges of the two steel beams are overlapped and placed in the receiving space. At this time, the bottom of the flanges of the two steel beams abuts against the bottom of the receiving space, and then the adjusting portion 22 is manually rotated. During the rotation of the adjusting portion 22, it moves towards the flange of the steel beam until the adjusting portion 22 completely abuts against the top of the flanges of the two steel beams, so as to lock the flanges of the two steel beams by the adjusting portion 22.

[0034] Furthermore, in this embodiment, an abutting portion 3 is further provided. The abutting portion 3 is fixedly connected to the second end of the first fixing structure 1. By abutting the abutting portion 3 against the flange of the steel beam, the force transmission effect can be further increased. If the abutting portion 3 is not provided, during the process of locking the flange of the steel beam, the abutting force is provided to the flange of the steel beam through the side wall of the first fixing structure 1 near the second end. The contact area between the side wall of the first fixing structure 1 near the second end and the flange of the steel beam is small, so the force transmission effect is also poor. The contact area of the abutting portion 3 abutting against the flange of the steel beam is larger than the contact area between the side wall of the first fixing structure 1 near the second end and the flange of the steel beam.

[0035] As Figure 2 shown, during the actual operation process, the flanges of the two steel beams are overlapped and placed in the accommodating space. At this time, the bottom of the flanges of the two steel beams abuts against the upper surface of the abutting portion 3. Then, the adjusting portion 22 is manually rotated. During the rotation of the adjusting portion 22, it moves towards the direction of the flange of the steel beam until the adjusting portion 22 completely abuts against the top of the flanges of the two steel beams, thereby locking the flanges of the two steel beams.

[0036] Specifically, in this embodiment, the shape of the abutting portion 3 is a cylinder with a diameter of 30 mm. Therefore, the contact area of the abutting portion 3 abutting against the flange of the steel beam is circular, and the contact area between the side wall of the first fixing structure 1 near the second end and the flange of the steel beam is linear. The former has a larger and more concentrated contact area compared to the latter. Therefore, the former has a better force transmission effect than the latter. And the abutting surface of the cylinder of the abutting portion 3 is closer to the flange of the steel beam than the side wall of the first fixing structure 1 near the second end, ensuring that the abutting portion 3 abuts against the flange of the steel beam.

[0037] Specifically, as an alternative implementation, the shape of the abutting portion 3 is a nut with a diameter of 30 mm. Using a nut with a diameter of 30 mm is more convenient for material selection compared to a cylinder. However, the force transmission effect of the abutting portion 3 in the form of a nut is worse than that of a cylindrical abutting portion 3. During the actual construction process, it can be selected according to the actual difficulty of material selection.

[0038] Specifically, in this embodiment, the first fixing structure 1 is bent into a "C" shape. As an alternative implementation, the first fixing structure 1 can also be bent into a square with one side open or other irregular open shapes; the specific size of the open shape can be adjusted to ensure that the thicknesses of the flanges of the two steel beams can be accommodated. However, bending the first fixing structure 1 into a "C" shape is simpler and more convenient.

[0039] It should be noted that the accommodating space refers to the space formed inside the opening of the first fixing structure 1 bent into a "C" shape.

[0040] It should be noted that in this embodiment, the first fixing structure 1 is bent by hot bending. Specifically, for hot bending, an induction coil is sleeved on the part of the steel pipe to be bent of the straight pipe by a pipe bending and pushing machine, the pipe head is clamped by a mechanical rotating arm, and intermediate frequency current is passed through the induction coil to heat the steel pipe. When the temperature of the steel pipe rises to the plastic state, mechanical thrust is applied at the rear end of the steel pipe to carry out bending. The bent part of the steel pipe is quickly cooled by a coolant. In this way, while heating, pushing, bending, and cooling, the bent pipe is continuously produced.

[0041] It should be noted that in this embodiment, the first fixing structure 1 is made of steel. The size of the first fixing structure 1 is a steel column with a diameter of 20 mm.

[0042] Obviously, the above embodiments are only examples clearly described and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the present invention.
