Description

Technical Field

[0001] The utility model relates to the technical field of building engineering, in particular to an assembled building shock-absorbing connection structure. Background Art

[0002] Building shock absorption (structural energy dissipation and shock absorption technology) is to set energy-absorbing devices at certain parts of the structure (such as supports, shear walls, joints or connectors), and generate friction, bending (or shearing, torsion), elastic-plastic (or viscoelastic) hysteresis deformation through the device to dissipate or absorb the energy of the earthquake input structure, so as to reduce the seismic response of the main structure, thereby avoiding damage or collapse of the structure and achieving the purpose of shock absorption control. When fixing lightweight prefabricated buildings such as plate buildings or wooden buildings with the bottom embedded parts, there is a lack of shock-absorbing structure between the embedded parts and the prefabricated parts. This not only causes a direct rigid collision connection between the parts and the embedded parts, resulting in a reduction in the service life of the parts, but also the seismic resistance of the lightweight prefabricated buildings is low, which is not conducive to improving the service life of the lightweight prefabricated buildings. Therefore, the utility model proposes a prefabricated building shock-absorbing connection structure to solve the problems existing in the prior art.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0018] See also Figure 1-3 , including a bottom plate 1, the top of the bottom plate 1 is fixedly connected with a lower protective shell 7, the top of the lower protective shell 7 is provided with a through hole 13, the through hole 13 passes through the top of the lower protective shell 7, one end of a plurality of first springs 11 distributed evenly are fixedly connected to the opposite sides of the interior of the lower protective shell 7, the top of the first spring 11 is fixedly connected with a support plate 10, the top of the support plate 10 is fixedly connected with one end of a support rod 14, the support rod 14 passes through the inside of the through hole 13, the top of the support rod 14 is fixedly connected with a top plate 2, one end of a plurality of second springs 15 distributed evenly are fixedly connected around the top of the support plate 10, and the other end of the second spring 15 is fixedly connected to the top of the lower protective shell 7. The first spring 11 greatly improves the shock resistance. When vibration occurs, the support rod 14 absorbs energy by shaking. The support plate 10 contacts the inner wall of the lower protective shell 7 to prevent excessive shaking that causes the support rod 14 to tilt and become unusable. When the support plate 10 moves downward, the second spring 15 applies an upward pulling force, which reduces the degree of downward movement of the support plate 10 and reduces the vibration response of the equipment.

[0019] See also Figure 1 The top of the top plate 2 is fixedly connected with a cross connection block 3, and a plurality of grooves 4 are evenly distributed around the cross connection block 3. By setting the cross connection block 3 and the groove 4, it is convenient to fix with a mortise and tenon structure, which greatly improves the installation fit of the device.

[0020] See also Figure 1-3 The inner middle of the lower protective shell 7 is fixedly connected with a limit block 12, the bottom of the top plate 2 is fixedly connected with an upper protective shell 5, and the top of the bottom plate 1 is fixedly connected with a buffer pad 6. The limit block 12 is used to limit the height of the support plate 10 to reduce the pressure of the support plate 10 on the first spring 11, thereby preventing the first spring 11 from being damaged and affecting its service life. The buffer pad 6 is used to prevent the upper protective shell 5 from directly contacting the bottom plate 1 when it moves downward. The main function of the buffer pad 6 is to alleviate the impact, vibration and noise generated by the object during movement or force. As a device for eliminating impact and reducing vibration, the buffer pad 6 can play a certain role in reducing the impact when the object is subjected to impact force, thereby protecting the equipment or object from damage.

[0021] See also Figure 1-2 The bottom of the bottom plate 1 is fixedly connected with a mute cotton 9. The mute cotton 9 can prevent the device from sliding during use, making the device more stable, reducing the risk of sliding and shaking, and avoiding accidental sliding or sliding noise. The use of the mute cotton 9 can greatly improve the stability and safety of the device and extend the service life of the device.
