Description

Technical Field

[0001] This utility model relates to the field of shock absorber technology, and in particular to a building shock absorption structure. Background Technology

[0002] Buildings refer to man-made assets, falling under the category of fixed assets, and include two main categories: houses and structures. Houses are engineering structures used for living, working, studying, producing, operating, entertaining, storing goods, and conducting other social activities. Structures, in contrast to buildings, refer to engineering structures other than houses, such as walls, roads, dams, wells, and tunnels. In timber-framed buildings, beams and columns are the components that bear the horizontal and vertical forces of the building structure, respectively, playing a crucial role in the overall stability of the building. Because timber columns bear vertical forces, they provide stable support when the building is subjected to vibrations. However, existing timber columns, directly fixed to column bases, only provide a certain degree of auxiliary stabilization.

[0003] Patent CN206090915U discloses a vibration-damping building structure, comprising a steel ball top seat, a column, a top seat steel ball groove, a column groove, a sealing cover, a device body groove, a box, a steel ball base, a base steel ball groove, a steel ball, a spring fixing groove, and a spring. The box contains a device body groove, with a steel ball base at the bottom. A base steel ball groove is located at the center above the steel ball base, containing a steel ball. A steel ball top seat is located above the steel ball, and a top seat steel ball groove is located at the center below the top seat. The top seat steel ball groove fits onto the steel ball. A column groove is located above the top seat, with the bottom end of the column inserted into the column groove. Four spring fixing grooves are located between the base steel ball groove and the four corners above the steel ball base, with the springs secured in the spring fixing grooves. The upper ends of the springs rest against the lower end of the top seat. A sealing cover is located above the box.

[0004] The aforementioned patents still have the following technical defects: due to the repeated compression of the spring in the shock absorption mechanism, the spring is prone to metal fatigue. If it is not replaced in time after a long period of use, it will affect the shock absorption effect on the building. Utility Model Content

The threaded rod and the mounting base plate are respectively installed at the upper and lower ends of the spring shock absorber. The mounting base plate and the support base have a detachable connection structure. The support ring is fixed on the threaded rod.

[0010] Multiple sets of mounting components are mounted on a ring plate along a circular array. Each mounting component includes a threaded sleeve, a guide rod, and a movable plate. The movable plate is positioned directly above the notch on the corresponding side.

[0020] Example 1

[0021] like Figures 1-3 As shown in the figure, the building vibration reduction structure proposed in this embodiment includes a support sleeve 1, a support base 2, multiple sets of vibration reduction mechanisms, and multiple sets of installation components.

[0022] The upper end of the support sleeve 1 is open. The support sleeve 1 is located directly above the support base 2. The bottom circumference of the support sleeve 1 is connected to an annular plate 4. The annular plate 4 has multiple notches 401. The multiple notches 401 are arranged in an annular array. There are at least six notches 401, of which at least three are reserved for replacing the new shock absorber mechanism. The notches 401 allow the spring shock absorber 3 to pass through.

[0023] Each shock absorption mechanism includes a spring shock absorber 3, a mounting base plate 5, a support ring 12, and a threaded rod 13. The spring shock absorber 3 is an automotive shock absorber. The threaded rod 13 and the mounting base plate 5 are respectively installed at the upper and lower ends of the spring shock absorber 3. The mounting base plate 5 and the support base 2 have a detachable connection structure. The support ring 12 is fixed on the threaded rod 13. The mounting base plate 5 and the support base 2 are connected by multiple bolts and multiple nuts. The multiple bolts are vertically connected to the support base 2. The mounting base plate 5 has through holes for the multiple bolts to pass through. The multiple bolts pass through the multiple through holes and are threadedly connected to the multiple nuts.

[0024] Multiple sets of mounting components are mounted on annular plate 4 in a circular array. The mounting components include threaded sleeve 6, guide rod 7 and movable plate 14. Movable plate 14 is located directly above the notch 401 on the corresponding side. Guide rod 7 is vertically connected to annular plate 4. Limit block 71 is provided at the upper end of guide rod 7. Movable plate 14 is slidably mounted on guide rod 7. Threaded sleeve 6 is rotatably mounted on movable plate 14. Knob 8 is provided at the upper end of threaded sleeve 6.

[0025] Specifically, in this technical solution, at least three sets of shock-absorbing mechanisms are installed between the support sleeve 1 and the support base 2. It should be noted that the support base 2 is fixedly installed on the ground, so that the bottom end of the support column that needs to be supported and shock-absorbing is located inside the support sleeve 1. The multiple sets of shock-absorbing mechanisms installed can play a shock-absorbing and buffering role for the supported column.

[0026] Since a spring is installed inside the spring damper 3, the spring will be repeatedly compressed during the damping process, causing metal fatigue. Therefore, the spring damper 3 is a vulnerable part and needs to be replaced after long-term use and damage. The following is the replacement process for the spring damper 3.

[0027] First, prepare no fewer than three sets of damping mechanisms. Pass the damping mechanisms through the corresponding side notches 401, and fix the mounting base plate 5 at the bottom of the spring damper 3 with bolts and nuts. This realizes the connection between the spring damper 3 and the support base 2. Then, place the threaded sleeve 6 on the upper end of the threaded rod 13, and place the support ring 12 on the lower end of the moving plate 14. Drive the threaded sleeve 6 to rotate by the knob 8, so that the threaded sleeve 6 is threadedly connected to the upper end of the threaded rod 13, thereby realizing the connection between the spring damper 3 and the spring damper 3. After the new set of damping mechanisms is installed, the adjacent old set of damping mechanisms can be removed. Alternatively, multiple new damping mechanisms can be installed before the old damping mechanisms are removed simultaneously.

[0028] Example 2

[0029] like Figure 3 As shown, this embodiment proposes a building vibration reduction structure. Compared with Embodiment 1, in this embodiment, each set of installation components is equipped with an anti-rotation mechanism on its side. The anti-rotation mechanism includes a gear 9, a limiting rod 10, and a sliding rod 11. The gear 9 is installed on the outer periphery of the bottom end of the threaded sleeve 6. The limiting rod 10 is vertically slidably disposed on the outer side wall of the support sleeve 1. The sliding rod 11 is vertically connected to the limiting rod 10 and is slidably disposed on the support sleeve 1. Before driving the threaded sleeve 6 to rotate, the limiting rod 10 is moved to the upper limit position. After the threaded sleeve 6 rotates to the set angle, the limiting rod 10 is moved downward to insert into the corresponding tooth groove on the gear 9, thereby completing the limitation of the angle of the threaded sleeve 6. It should be noted that the cross section of the limiting rod 10 is adapted to the tooth groove of the gear 9.

[0030] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
