Description

Technical Field

[0001] This invention relates to the field of damper construction technology, and in particular to a gapless damper connection device and installation method. Background Technology

[0002] In residential buildings, offices, shopping malls, hospitals, and other similar locations, dampers are often required to be installed on connecting walls. Traditional viscous dampers are installed by connecting ear plates welded to an embedded plate. These ear plates have holes, and the damper is connected to the ear plate via pins. Due to the holes in the ear plates, a certain gap exists between the damper and the ear plate, resulting in no energy loss under small displacements, which weakens the structure's vibration reduction effect. Summary of the Invention

[0003] To improve the vibration reduction effect of dampers, this invention provides a gapless damper connection device and installation method.

[0004] In a first aspect, the present invention provides a gapless damper connection device, which adopts the following technical solution:

[0005] A gapless damper connection device is provided, which connects the damper to an upper or lower embedded plate. It includes a connecting ear plate with bolt holes, the connecting ear plate is perpendicular to the damper and connected by high-strength bolts, and a positioning ear plate is vertically fixed to the side of the connecting ear plate away from the damper. Both the connecting ear plate and the positioning ear plate are welded and fixed to the upper or lower embedded plate.

[0006] By adopting the above technical solution, the use of this gapless damper connection device effectively eliminates the connection gap of the damper, realizes the gapless connection of the damper, and enhances the vibration reduction effect of the structure.

[0007] Optionally, the connecting ear plate has a double-sided bevel on the side used to connect with the upper or lower embedded plate, and the positioning ear plate has a double-sided bevel on the side used to connect with the upper or lower embedded plate.

[0008] By adopting the above technical solution, the ear plate is opened with a two-way bevel, which effectively solves the problem of deformation caused by heat during welding, resulting in the damper installation misalignment. On-site installation is simple and the installation accuracy and construction speed of the damper are improved.

[0009] Optionally, the double-sided bevel of the positioning ear plate may have a weld hole at one end near the double-sided bevel of the connecting ear plate.

[0010] By adopting the above technical solution, the design of the through-hole facilitates full welding of the bevel of the connecting ear plate when welding the connecting ear plate, thereby improving the connection strength with the upper or lower embedded plate.

[0011] Optionally, multiple bolt holes are evenly distributed around the center of the connecting ear plate.

[0012] By adopting the above technical solution, the connecting lug and the damper are subjected to uniform force and have high connection strength.

[0013] Secondly, the present invention provides a method for installing a gapless damper, comprising the following steps:

[0014] S1. Fix the embedded plate to the connecting wall;

[0015] S2. Weld the connecting ear plate to the positioning ear plate;

[0016] S3. Bolt connection between damper and connecting lug;

[0017] S4. Hoist and weld the damper for installation.

[0018] Optionally, in S3, initial tightening is performed first to ensure that the damper and the connecting lug plate fit tightly together, and then final tightening is performed to ensure that the tensile force of the high-strength bolt reaches the required preload value.

[0019] In summary, the present invention has at least one of the following beneficial technical effects:

[0020] The use of this gapless damper connection device effectively eliminates the connection gap of the damper, realizes the gapless connection of the damper, and enhances the vibration reduction effect of the structure.

[0021] The double-sided bevel of the ear plate effectively solves the problem of deformation caused by heat during welding, which leads to the misalignment of the damper during installation. On-site installation is simple and the installation accuracy and construction speed of the damper are improved.

[0022] The design of the through-hole facilitates full welding of the bevel of the connecting ear plate when welding the connecting ear plate, thereby improving the connection strength with the upper or lower embedded plate. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 The present invention will be described in further detail below.

[0030] This invention discloses a gapless damper connection device and installation method. (Refer to...) Figure 1 The upper connecting wall 1 has an upper embedded plate 3 fixed on its bottom surface, and the lower connecting wall 2 has a lower embedded plate 4 fixed on its top surface. The damper 5 is located between the upper embedded plate 3 and the lower embedded plate 4. The gapless damper connecting device is used to connect the damper 5 to the upper embedded plate 3 or the lower embedded plate 4.

[0031] Reference Figures 1-4 The gapless damper connection device includes a connecting lug 6, on which multiple bolt holes 60 are circumferentially formed. The damper 5 is installed on the connecting lug 6 by high-strength bolts 7. The axis of the damper 5 is perpendicular to the surface of the connecting lug 6. The end face of the connecting lug 6 used for welding with the upper embedded plate 3 or the lower embedded plate 4 is set in the form of a double-sided bevel to prevent uneven heating during welding and reduce deformation.

[0032] Reference Figures 1-4 A positioning ear plate 8 is vertically welded to the side of the connecting ear plate 6 away from the damper 5. The end face of the positioning ear plate 8 used for welding with the upper embedded plate 3 or the lower embedded plate 4 is set in the form of a double-sided bevel to prevent uneven heating during welding and reduce deformation. At the same time, a weld hole 80 is opened at the end of the bevel of the positioning ear plate 8 near the connecting ear plate 6 so that the bevel of the connecting ear plate 6 can be fully welded when welding the connecting ear plate 6, thereby improving the connection strength with the upper embedded plate 3 or the lower embedded plate 4.

[0033] Reference Figure 5 The method for installing a gapless damper according to an embodiment of the present invention includes the following steps:

[0034] S1. Fix the embedded plate to the connecting wall, specifically including: fixing the upper embedded plate 3 to the upper connecting wall 1 reinforcement, fixing the lower embedded plate 4 to the lower connecting wall 2 reinforcement, setting up the formwork and pouring concrete, and waiting for the concrete to solidify before proceeding to the next step.

[0035] S2. Weld the connecting ear plate 6 and the positioning ear plate 8. Specifically, the connecting ear plate 6 and the positioning ear plate 8 are welded together according to the installation dimensions of the damper 5 reserved between the upper connecting wall 1 and the lower connecting wall 2. Both the connecting ear plate 6 and the positioning ear plate 8 adopt the form of double-sided bevel.

[0036] S3. Bolt connection between damper 5 and connecting lug 6, specifically including: using high-strength bolts 7 to connect damper 5 and connecting lug 6, first performing initial tightening to make damper 5 and connecting lug 6 fit tightly together, and then performing final tightening to make the tensile force value of high-strength bolts 7 reach the required pre-tension value.

[0037] S4. Hoisting and welding the damper 5, specifically including: after the damper 5 is connected to the connecting lug 6, it is installed as a whole. The damper 5 is hoisted to the installation position and spot welded. After it is firmly fixed, the welds between the positioning lug 8 and the upper embedded plate 3 or the lower embedded plate 4 are symmetrically welded on both sides. Then the welds between the connecting lug 6 and the upper embedded plate 3 or the lower embedded plate 4 are welded, so as to achieve the purpose of seamless connection of the damper 5.

[0038] The use of this gapless damper connection device effectively eliminates the connection gap of damper 5, achieving a gapless connection of damper 5 and enhancing the vibration reduction effect of the structure. The double-sided bevel of the ear plate effectively solves the problem of deformation caused by heat during welding, which leads to the misalignment of damper 5 during installation. On-site installation is simple and improves the installation accuracy and construction speed of damper 5.

[0039] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
