Description

Technical Field

[0001] The invention relates to the field of steel structure top beam components, in particular to a steel structure top beam cantilever component. Background Art

[0002] H-shaped steel is widely used in steel structure top beams due to its high strength and anti-bending effect. Especially for large-span steel structure top beams, H-shaped steel does not require complex supports and can improve space utilization. When using H-shaped steel as a large-span top beam, two symmetrically inclined H-shaped steels are generally connected in the middle to make the middle part of the top beam bulge upward, which can improve the anti-sinking effect of the middle part of the top beam.

[0003] However, the middle part of the top beam with a large span still has the risk of deformation and sinking. For this type of structure, inclined auxiliary support rods are generally added at both ends of the top beam. This method cannot provide effective anti-deformation support for the middle part of the top beam, or columns are set in the middle part of the top beam to vertically support the top beam. The columns set in this way will divide the internal space of the building. Therefore, it is of great significance to provide a cantilevered structure that can improve the anti-deformation strength of the middle part of the large-span top beam without occupying the internal space of the building. Summary of the invention

[0004] In order to make up for the deficiencies of the existing technical problems, the purpose of the present invention is to provide a steel structure top beam cantilever component for solving the problem of lack of support in the middle part of the steel structure top beam with an ultra-large span without occupying building space.

[0008] Preferably, annular teeth are arranged around the edge of the rotating position of the blade, racks are vertically arranged at the angle positions of the cross plate, the racks are meshed and connected to the annular teeth, the bottoms of the racks are connected to the support plate, and a spring is connected between the support plate and the cross plate to apply an upward elastic force to the racks.

[0010] Preferably, movable grooves penetrating the surface of the slider are opened at the upper and lower parts of the guide hole, and movable parts are arranged in the movable grooves. The surface of the guide column has an inclined protrusion. When the slide moves toward the base, the inclined protrusion squeezes the movable part to contact the flange plate of the H-shaped steel beam in an expanding manner.

[0011] Preferably, the movable part is an eccentric wheel, which rotates in a movable groove, and the inclined protrusion squeezes the eccentric wheel to rotate, so that the eccentric wheel deflects and squeezes the flange plate of the H-shaped steel beam.

[0012] Preferably, the movable part is a steel ball, which is linearly movable in a movable groove, and the inclined protrusion squeezes the steel ball to expand and move, so that the steel ball squeezes the flange plate of the H-shaped steel beam.

[0013] Preferably, the movable part is a slider, which is linearly slidably arranged in a movable groove, and the inner end of the slider is inclined, and the inclined surface protrudes against the expansion and sliding of the slider, so that the outer end plane of the slider squeezes the flange plate of the H-shaped steel beam.

The connector is supported by two longitudinal support rods distributed in an "eight" shape, and two transverse support rods distributed in a V shape support the middle of the H-shaped steel beam, forming a three-dimensional structure to suspend the top beam, thereby improving the anti-deformation strength of the entire middle area of ​​the top beam and ensuring the stability of the top beam.

[0018] 2. The present invention connects the transverse support rods and the longitudinal support rods respectively through elastically retractable transverse connecting seats and longitudinal connecting seats. When the top beam sinks and presses the transverse support rods and the longitudinal support rods, the elastic deformation of the transverse connecting seats and the longitudinal connecting seats provides a buffering force for the sinking of the top beam, thereby comprehensively improving the seismic stability of the top beam.

[0019] 3. The present invention arranges a movable part in the slide seat. When the top beam sinks excessively, the slide seat slides excessively, causing the inclined surface protrusion to resist the expansion of the movable part. The expanded movable part is squeezed and contacted with the flange plate of the H-shaped steel beam, forming multi-point friction on the slide seat, which has a braking effect and prevents the top beam from sinking excessively.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] Embodiment 1: Figure 1 , Figure 2 As shown, the steel structure has a plurality of longitudinally arranged top beams, which are composed of two symmetrically inclined H-shaped steel beams 8. The far ends of the two H-shaped steel beams 8 are connected to the columns of the steel structure, and the corresponding ends of the two H-shaped steel beams 8 are commonly connected to the connecting parts 2, so that the top beam forms a convex shape with the middle part higher than the two ends.

[0033] like Figure 3 As shown, the connecting member 2 includes a cross plate 21, and blades 22 are rotatably installed on the left and right sides of the cross plate 21 through pins. The blades 22 are flat against the web of the H-shaped steel beam 8 and are fixed by bolts. Since the H-shaped steel beam 8 is hinged to the cross plate 21 through the blades 22, the middle part of the top beam has a certain amount of sinking deformation.

[0034] like Figure 2 As shown, the H-shaped steel longitudinal beam 1 is arranged directly below the connector 2 and is cross-staggered with the top beam. Both ends of the H-shaped steel longitudinal beam 1 are connected to the skeleton at the edge of the steel structure. The H-shaped steel longitudinal beam 1 supports the H-shaped steel cross beam 8 through the cross support rod 4 and the longitudinal support rod 3.

[0035] like Figure 2 , Figure 5 As shown, the installation of the cross support rod 4 is as follows: a hinge seat 7 is fixedly installed on the surface of the H-shaped steel longitudinal beam 1 by bolts, and the hinge seat 7 is located directly below the connector 2. Two cross support rods 4 are symmetrically hinged on both sides of the H-shaped steel longitudinal beam 1 by the hinge seat 7. The two cross support rods 4 are distributed in a V-shape expansion upward, and the top of the cross support rod 4 is hinged to support the middle of the H-shaped steel cross beam 8 through the cross connector 5;

[0036] like Figure 2 , Figure 3 As shown, the longitudinal support rod 3 is installed as follows: two longitudinal support rods 3 are symmetrically hinged on the front and rear sides of the cross plate 21, and the two longitudinal support rods 3 are expanded and distributed in an eight-shaped shape downward, and the bottom ends of the longitudinal support rods 3 are hinged to the H-shaped steel longitudinal beam 1 through the longitudinal connecting seat 6.

[0037] The corresponding ends of the two H-shaped steel beams 8 are connected to the connector 2 in a hinged manner, replacing the traditional bolt hard connection method, ensuring that the middle part of the top beam has movable space to avoid the middle part of the top beam from sinking or vibrating and causing the hard connection to break. When the middle part of the top beam sinks, the connector 2 is in the area with the largest deformation. The two longitudinal support rods 3 distributed in an "eight" shape gather and support the connector 2, effectively increasing the anti-deformation support strength of the middle part of the top beam. The middle part of the H-shaped steel beam 8 is supported by two V-shaped transverse support rods 4, so as to achieve dispersed force support for the top beam and improve the anti-deformation strength of the entire middle area of ​​the top beam.

[0038] like Figure 3 , Figure 4 As shown, a half circle of annular teeth 23 are arranged around the edge of the rotation position of the blade 22, and racks 24 are vertically arranged at the angle position of the cross plate 21. The racks 24 are engaged and connected to the annular teeth 23, and the bottom of the racks 24 are fixedly connected to the support plate 25. A spring is connected between the support plate 25 and the cross plate 21 to apply an upward elastic force to the racks 24. When the middle part of the top beam sinks, the end of the H-shaped steel beam 8 drops, causing the connection point between the blade 22 and the cross plate 21 to rotate. The racks 24 are driven by the engagement of the annular teeth 23 to push the support plate 25 to drop relative to the cross plate 21, and the spring is stretched. The elastic force of the spring provides a counterforce to alleviate the downward amplitude of the middle part of the top beam, and also plays an elastic buffering role.

[0039] like Figure 6 As shown, the longitudinal connection seat 6 has the same structure and function as the transverse connection seat 5. The transverse connection seat 5 includes a base 51 and a slide 52. The base 51 is fixedly connected to the web of the H-shaped steel beam 8 by bolts. The slide 52 is slidably arranged between the flange plates of the H-shaped steel beam 8. A guide column 53 is fixed on the surface of the base 51. The guide column 53 points to the slide 52. A guide hole 54 is provided on the surface of the slide 52. The guide column 53 and the guide hole 54 are slidably inserted in a position so that the slide 52 can move linearly relative to the base 51. The surface of the slide 52 has a hinge hole 55 for rotating the end of the transverse support rod 4. A spring is connected between the slide 52 and the base 51. The spring exerts an elastic force on the slide 52 to move away from the base 51.

[0040] When the middle part of the top beam sinks, the cross support rod 4 has a tendency to expand and move under the action of pressure, and the end of the cross support rod 4 transfers the load to the slide 52, which is guided by the guide column 53 to move the slide 52 closer to the base 51. At this time, the spring is compressed, and the elastic force of the spring resists the pressure on the cross support rod 4, so that the cross support rod 4 supports the top beam, and the elastic sliding buffering effect of the slide 52 makes the middle part of the top beam have a good seismic effect. Similarly, the longitudinal connecting seat 6 also plays an elastic supporting role for the longitudinal support rod 3. The supporting directions of the longitudinal support rod 3 and the cross support rod 4 to the top beam are perpendicular to each other, forming a three-dimensional structure to suspend the top beam.

[0041] like Figure 7 As shown, movable grooves 57 penetrating the surface of the slider 510 are provided at the upper and lower parts of the guide hole 54, and an eccentric wheel 58 is rotatably installed in the movable groove 57 as a movable part. The surface of the guide column 53 has an inclined protrusion 56, and the tail of the inclined protrusion 56 extends to the surface of the base 51 to increase the connection area between the guide column 53 and the base 51. The front end of the inclined protrusion 56 is inclined.

[0042] Under normal conditions, there is a distance between the eccentric wheel 58 and the inclined protrusion 56. Within this distance, the movement of the slide 52 is not affected by the eccentric wheel 58, which only provides elastic buffering force. When the sinking amplitude of the top beam increases, the cross support rod 4 pushes the slide 52 to move a distance beyond this range. At this time, the inclined protrusion 56 contacts the eccentric wheel 58 and deflects, causing the eccentric wheel 58 to squeeze the flange plate of the H-shaped steel beam 8 outward, forming multi-point friction, increasing the sliding friction force of the slide 52, achieving a braking effect, and preventing the top beam from falling excessively.

[0043] like Figure 7 As shown, the slide seat 52 is composed of a first shell body 521 and a second shell body 522. The first shell body 521 and the second shell body 522 are fixed together by screws to form a complete guide hole 54 and a movable groove 57. The first shell body 521 and the second shell body 522 are separated by removing the screws to facilitate the assembly of the eccentric wheel 58 in the movable groove 57.

[0044] Embodiment 2: Figure 8 As shown, a steel ball 59 is arranged in the movable groove 57 as a movable part, and the steel ball 59 can move in a straight line along the movable groove 57. When the sinking amplitude of the top beam increases, the slide seat 52 moves to make the inclined protrusion 56 contact the steel ball 59, so that the steel ball 59 moves outward to expand and squeeze the flange plate of the H-shaped steel beam 8, forming multi-point friction, increasing the sliding friction force of the slide seat 52, playing a braking effect, and preventing the top beam from excessively descending.

[0045] Embodiment 3: Fig. 9 As shown, a slider 510 is linearly slidingly arranged in the movable groove 57 as a movable part, and the inner end of the slider 510 is in the shape of an inclined surface. When the sinking amplitude of the top beam increases, the slide seat 52 moves to make the inclined surface protrusion 56 squeeze the slider 510, so that the slider 510 slides outward to expand the plane and squeeze the flange plate of the H-shaped steel beam 8, forming multi-point friction, increasing the sliding friction force of the slide seat 52, achieving a braking effect, and preventing the top beam from dropping excessively.

[0046] Embodiment 4: Fig.10 As shown, a swing arm 511 is rotatably arranged in the movable groove 57 as a movable part. When the sinking amplitude of the top beam increases, the slide 52 moves to make the inclined protrusion 56 resist the expansion and rotation of the swing arm 511, so that the swing arm 511 squeezes and contacts the flange plate of the H-shaped steel beam 8, forming multi-point friction, increasing the sliding friction force of the slide 52, achieving a braking effect, and preventing the top beam from dropping excessively.

[0047] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the invention.
