Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a vibration-damping beam structure for building construction. Background Technology

[0002] In construction projects, beams and columns are mostly constructed using steel reinforcement frames and concrete pouring, and there is a large amount of machinery and equipment on the construction site. When the machinery and equipment are in operation, they generate vibration waves, which propagate upwards along the mounting supports. Beams located at high altitudes are prone to breakage due to the influence of wind and the continuous propagation of vibrations, thus causing serious loss of life and property.

[0003] Existing vibration-damping beam structures typically employ energy-dissipating substructures, or vibration-damping buffer structures, placed inside or at the top of the beams and columns to counteract the forces caused by vibrations, thereby making the entire structure more stable. However, the vibration isolation effect of this passive vibration isolation system is often limited by factors such as the quality of the materials and their natural frequency, making it difficult to adapt to various complex working conditions and changes in vibration sources. In particular, its vibration reduction effect is relatively limited for some low-frequency vibrations. Utility Model Content

[0004] Based on the above description, this utility model provides a vibration damping beam structure for building construction, which solves the shortcomings of existing vibration damping beam structures that are difficult to adapt to various complex working conditions and changes in vibration sources, resulting in relatively limited vibration damping effects.

[0005] A vibration-damping beam structure for building construction includes a beam and a column. The top surface of the beam and column is provided with an installation groove at its center. A connecting beam is placed in the installation groove. A vibration-damping component is also provided on the bottom surface of the installation groove. The top surface of the vibration-damping component is in close contact with the bottom surface of the connecting beam. The side walls of the connecting beam extend outward to the outside of the beam and column and are provided with hinge seats on their bottom surfaces. An auxiliary support is also provided on the side walls of the beam and column. The top of the auxiliary support is movably connected to the hinge seat and applies an upward thrust.

[0006] This utility model is achieved through the following technical solution:

[0007] Furthermore, the connecting beam is configured as a cross-shaped structure, and the four sides of the mounting groove extend outward to form four openings. The four sides of the connecting beam fit perfectly into the openings. When the top surface of the connecting beam is in contact with the top building, the top surface of the connecting beam is flush with the top surface of the beam and column.

[0008] Furthermore, the shock absorption assembly includes an air spring fixedly disposed at the center of the bottom surface of the mounting groove. The air spring is cylindrical and has a circular connecting plate at the top. The four sides of the connecting plate are respectively provided with rectangular protrusions. The bottom surface of the connecting beam is provided with a spline hole at the center and is adapted to be inserted into the connecting plate.

[0009] Furthermore, the auxiliary support includes fixed seats arranged around the four sides of the beam and column, each fixed seat being fixedly connected to the beam and column, and the top surface of the fixed seat being set as a horizontal plane and provided with an installation ring. A diagonal brace is provided above the fixed seat, and the bottom of the diagonal brace is provided with a lifting ring and locked to the installation ring by bolts. The top of the diagonal brace is provided with a hinge end and is movably connected to the hinge seat on the bottom surface of the connecting beam.

[0010] Furthermore, the diagonal brace is configured as a spring damper, and the overall tilt angle of the diagonal brace is set to 45-60°.

[0011] Furthermore, reinforcing ribs extend outward below the openings on all four sides of the mounting groove. These reinforcing ribs are triangular in shape and their top surfaces are flush with the bottom surfaces of the openings.

[0012] Furthermore, the top surface of the reinforcing rib is provided with a shallow groove, and a buffer seat is fixedly installed inside the shallow groove, with the bottom surface of the buffer seat closely fitting the bottom surface of the connecting beam.

[0013] Furthermore, the buffer seat is configured as a rubber vibration isolation support.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0015] This application improves upon existing damping beams by combining auxiliary support components with damping modules within the mounting slots to create a damping structure with active damping capabilities. This structure effectively counteracts low-frequency vibrations by actively applying a certain thrust, thus enhancing overall stability. Furthermore, the damping modules, through the interaction of air springs and buffer seats, isolate downward vibration transmission, significantly improving the stability of the entire beam structure. In addition, this structure can be connected to adjacent beams and columns via connecting beams to form a unified support system, further enhancing construction safety. Attached Figure Description

[0020] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0021] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them.

[0022] Combination Figure 1-3 As shown, a vibration-damping beam structure for building construction includes:

[0023] Beam 1 is the main structure of the entire shock-absorbing beam, used for support. It has a mounting groove 11 on its top, which extends outward and forms 4 openings on the side wall of beam 1.

[0024] The connecting beam 2 is set in a cross shape. Its purpose is to form a whole with other beams and columns 1 nearby through the cross-shaped connecting beam 2, thereby improving the support effect of the entire construction floor. The connecting beam 2 can also be changed to a straight structure according to the actual use.

[0025] The vibration damping component 3 is set on the bottom surface of the mounting groove 11 and fits against the bottom of the connecting beam 2 to directly provide auxiliary support for the connecting beam 2 and at the same time play a vibration isolation role.

[0026] The auxiliary support is installed on the side wall of beam-column 1 and connected to the bottom surface of connecting beam 2 by means of diagonal bracing, thereby applying an upward thrust to it and improving the seismic resistance of the entire support structure.

[0027] Specifically, in this embodiment, the connecting beam 2 adopts a cross-shaped structure, and the protruding parts on the four sides are respectively engaged with the openings, thus combining with the beam and column 1 into a whole. Its top is used to provide auxiliary support for the top floor building. That is, when the top floor building is attached to the connecting beam 2, it will apply downward pressure, so that the top surface of the connecting beam 2 is flush with the top surface of the beam and column 1. At this time, the connecting beam 2 also applies pressure to the shock absorption component 3, while the auxiliary support component will apply an opposite thrust due to the compression, so that when it is affected by vibration, especially low-frequency vibration, it can offset some of the stress, thereby improving the stability of the entire beam and column 1.

[0028] The shock absorption assembly 3 includes an air spring 31 fixedly installed inside the mounting groove 11. The bottom of the air spring 31 is locked to the bottom surface of the mounting groove 11 by bolts. A connecting plate 32 is provided on its top. The connecting plate 32 is circular and has a rectangular protrusion on its side wall. A spline hole that matches the connecting beam 2 is provided at the center of the bottom surface, so that the connecting plate 32 can be smoothly inserted into the hole to complete the limiting installation. Therefore, when the top building vibrates, the air spring 31 can be used to effectively absorb and block it, thereby preventing the vibration from being transmitted downward and improving the stability of the entire beam and column 1.

[0029] The auxiliary support assembly 4 includes four fixed seats 41 set on the side wall of the beam-column 1. The beam-column 1 adopts a rectangular structure, so the fixed seats 41 are respectively arranged at the center of the four surfaces of the column. The fixed seats 41 are provided with mounting rings on the top surface. A diagonal brace 42 is also provided above the fixed seats 41. The top and bottom ends of the diagonal brace 42 are respectively provided with lifting rings. The bottom lifting ring and the mounting ring are movably connected by bolts, so that they can rotate around the screw. The top lifting ring is movably connected to the hinge seat on the bottom surface of the connecting beam 2.

[0030] In addition, the diagonal brace 42 is set as a damping spring. Therefore, when the connecting beam 2 at the top is pressed downward, the top of the diagonal brace 42 can contract inward and absorb the vibration. At the same time, the reverse thrust of the spring is used to apply an opposite force upward. The angle of the diagonal brace 42 is set to 45°-60°. This active upward thrust from all four sides can effectively counteract the low-frequency vibration of the top building, thereby improving the support effect. It can also effectively enhance the support strength of the beam and column 1 for the side force, and greatly improve the stability of the combination of the connecting beam 2 and the beam and column 1.

[0031] In addition, a reinforcing rib 5 is provided on the side wall of the beam-column 1. The reinforcing rib 5 is located below the opening and is arranged in a triangular shape. Its top surface is flush with the bottom surface of the connecting beam 2. At the same time, a shallow groove is provided on its top surface, and a buffer seat 51 is fixedly installed inside the shallow groove. The top surface of the buffer seat 51 is in contact with the bottom surface of the connecting beam 2. The purpose is to effectively utilize the triangular structure to improve the support effect of the beam-column 1 on the connecting beam 2. At the same time, the buffer seat 51 is used in conjunction with the shock absorption component 3 to further improve the seismic resistance and vibration isolation effect, so as to enhance the stability of the entire beam-column 1.

[0032] Based on the above structure, multiple damping beams should be installed, that is, multiple beams 1 should be installed vertically, and the connecting beams 2 at the top should be used to form a whole, thereby expanding the support area and improving the seismic resistance by utilizing the damping structure at the top.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the technical solutions of the embodiments of this utility model.
