Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a vibration damping beam for building construction. Background Technology

[0002] Beams used in building construction are key components that bear horizontal loads in building structures. They are mainly used to connect vertical load-bearing structures such as columns and walls, span spaces and transfer upper loads to ensure the integrity and stability of the building structure. In order to reduce the damage to the building structure caused by vibrations generated in the construction scene, a type of vibration damping beam is usually used in building engineering.

[0003] Existing damping beams only focus on reducing impact in one direction, relying mostly on rigid connections in the horizontal direction. This makes it difficult to effectively transmit and absorb horizontal vibration energy, resulting in horizontal forces acting directly on the main structure, which leads to poor damping performance of the damping beams. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a vibration damping beam for building construction, which aims to improve the problem that the existing technology only focuses on reducing energy impact in one direction, resulting in poor vibration damping effect.

[0013] This utility model has the following beneficial effects:

[0014] 1.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-3 An embodiment of this utility model provides: a vibration damping beam for building construction, including a vibration damping beam body 1, a first fixing block 2 fixedly connected to the bottom surface of the vibration damping beam body 1, a first shock absorber 3 rotatably connected to the left side of the first fixing block 2, a connecting piece 4 rotatably connected to the left side of the first shock absorber 3, a movable column 5 fixedly connected to the bottom of the connecting piece 4, a positioning column 9 fixedly connected to the top of the connecting piece 4, a second shock absorber 17 rotatably connected to the left side of the connecting piece 4, a hollow column 7 slidably connected to the bottom end of the movable column 5, a support column 8 fixedly connected to the bottom end of the hollow column 7, a connecting frame 11 fixedly connected to the top of the support column 8, a compression spring 6 fixedly connected to the top of the connecting frame 11, and a connecting mechanism provided on the surface of the vibration damping beam body 1;

[0024] Specifically, when the vibration intensity in the construction environment is low, there is no need for the two shock absorbers to work together. By removing the second shock absorber 17, the absorption of vibration energy and the reduction of impact can be completed solely by the impact reduction effect of the first shock absorber 3, the elastic potential energy conversion of the compression spring 6, and the sliding transmission of the moving column 5. This avoids the energy reduction impact redundancy caused by the simultaneous action of the two shock absorbers in low vibration scenarios, so that the vibration isolation effect matches the actual vibration intensity and improves the adaptability of the structure to different environments.

[0025] Reference Figure 4 The connecting mechanism includes a first fixing plate 13, the rear surface of the first fixing plate 13 is attached to the front surface of the shock-absorbing beam body 1, a first fixing member 12 is attached to the bottom front side of the first fixing plate 13, the bottom surface of the first fixing member 12 is attached to the support column 8, a first connecting rod 15 and a second connecting rod 16 are rotatably connected to the top of the first fixing plate 13, and a second fixing plate 14 is attached to the rear surface of the shock-absorbing beam body 1.

[0026] Specifically, the rear surface of the first fixing plate 13 is attached to the front surface of the shock-absorbing beam body 1, providing initial positioning for their relative positions and reducing the gap between them to prevent additional shaking during vibration. The first connecting rod 15 and the second connecting rod 16 can rotate relative to each other around the connection point. The second fixing plate 14 is rotatably connected to both the first connecting rod 15 and the second connecting rod 16, so that the first fixing plate 13 and the second fixing plate 14 form an adjustable linkage structure through the first connecting rod 15 and the second connecting rod 16. When it is necessary to adapt to shock-absorbing beam bodies 1 of different sizes, the distance between the first fixing plate 13 and the second fixing plate 14 can be changed by adjusting the relative angle of the first connecting rod 15 and the second connecting rod 16, thereby meeting the fixing requirements of shock-absorbing beam bodies 1 of different widths and improving the applicability of the connection mechanism.

[0027] Reference Figure 1 The first fixing member 12 has a fixing screw hole 20 on its surface. The fixing screw hole 20 is threaded with a fixing bolt on its inner wall. The fixing bolt is threaded with the support column 8.

[0028] Specifically, the first fixing member 12 is attached to the first fixing plate 13 and the support column 8, and the fixing bolts are used in conjunction with the fixing screw holes 20 on the surface to fix the first fixing plate 13 and the support column 8 together, thereby limiting the displacement of the first fixing plate 13 on the support column 8 and enhancing the stability of the overall connection.

[0029] Reference Figure 3 The bottom left and right sides of the shock-absorbing beam body 1 are provided with positioning holes 10, and the positioning column 9 is threadedly connected to the positioning hole 10.

[0030] Specifically, during the assembly process, the positioning pin 9 is screwed into the positioning hole 10 by the thread, which can strictly limit the horizontal displacement and rotation angle of the connecting piece 4 relative to the main body of the shock-absorbing beam 1, and avoid uneven force on the connecting piece 4 due to installation deviation.

[0031] Reference Figure 2 The second shock absorber 17 is rotatably connected to the left side of the second fixing block 18, and the second fixing block 18 is fixedly connected to the bottom surface of the shock absorber beam body 1.

[0032] Specifically, when the vibration energy is transmitted to the second shock absorber 17 through the connector 4, the second shock absorber 17 will swing to a certain extent with the energy impact, so that the shock absorber can adaptively adjust the angle according to the direction of the force, avoid the force transmission jam caused by rigid connection, and ensure that the energy can be smoothly introduced into the second shock absorber 17 to reduce the impact.

[0033] Reference Figure 4 The second fixing plate 14 has a second fixing member 19 attached to its bottom rear side, and the bottom surface of the second fixing member 19 is attached to the support column 8.

[0034] Specifically, the second fastener 19 is attached to the second fixed plate 14 and the support column 8, so that the pressure from the damping beam body 1 on the second fixed plate 14 can be transmitted to the support column 8 through the second fastener 19. The pressure is dispersed by the bearing capacity of the support column 8, and the second fixed plate 14 is prevented from deforming due to being subjected to force alone.

[0035] Reference Figure 4 The first link 15 and the second link 16 are rotatably connected, and the second fixed plate 14 is rotatably connected to the first link 15 and the second link 16 respectively;

[0036] Specifically, when it is necessary to adapt to the damping beam body 1 of different widths, the distance between the first fixing plate 13 and the second fixing plate 14 can be changed by adjusting the included angle between the connecting rods; the time distance increases when the included angle increases and decreases when the included angle decreases, thereby achieving a wrap-around fit to the damping beam body 1 of different sizes, ensuring that the connecting mechanism can stably clamp damping beams of various specifications.

[0037] Reference Figures 1-3 The bottom surface of the movable column 5 is slidably connected to the inner wall of the connecting frame 11, and the top surface of the hollow column 7 is fixedly connected to the connecting frame 11.

[0038] Specifically, when the compression spring 6 expands or contracts due to vibration, it will cause the moving column 5 to slide along the inner wall of the connecting frame 11. The connecting frame 11 and the hollow column 7 can ensure that the moving column 5 always moves in the vertical direction, avoiding lateral deviation or tilting during the sliding process.

[0039] Working principle: When vibration occurs during construction, the compression spring 6 is fixed to the top of the connecting frame 11 and fixedly connected to the moving column 5. The bottom end of the moving column 5 extends into the hollow column 7 fixed to the top of the support column 8. The moving column 5 is fixedly connected to the connecting piece 4. When the compression spring 6 converts the energy generated by the vibration into elastic potential energy, it can drive the moving column 5 to move up and down. Thus, the energy generated by the vibration is transmitted to the first shock absorber 3 and the second shock absorber 17 connected to the left and right sides of the connecting piece 4 through the moving column 5, so that the main body of the shock-absorbing beam 1 has good shock absorption performance.

[0040] Regarding the connection of the damping beam body 1, the surfaces of the first fixing plate 13 and the second fixing plate 14 are connected to the first connecting rod 15 and the second connecting rod 16. The first fixing plate 13 and the second fixing plate 14 can achieve the initial fixation of the damping beam body 1. The first fixing member 12 can fix the first fixing plate 13 and the second fixing plate 14 to the top of the support column 8. Since the first connecting rod 15 and the second connecting rod 16 are rotatably connected, the distance between the first fixing plate 13 and the second fixing plate 14 is adjustable, so that damping beam bodies 1 of different sizes can be fixedly connected.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
