Problems solved by technology

[0005] But these existing patents also have the following defects: 1. in the device, all rely on the spring members fixedly arranged along the horizontal direction to realize shock absorption and buffering. Compression and elongation, the spring itself will also directly produce a rebounding reverse force in the horizontal direction after being compressed and stretched
Therefore, the active force and reaction force of the spring are converted back and forth in the horizontal direction, which makes the actual shock absorption effect of the device and the effect of reducing the left and right swing of the building poor.
2 The function of the anti-seismic joint itself is to avoid the impact on adjacent building units when a single building unit collapses and falls, and the structure of the existing anti-seismic joint shock-absorbing devices is fixedly installed between adjacent buildings, so when a single building unit When it collapses and falls, it will act on the adjacent building units through the traction of the shock absorbing device, which greatly reduces the function and significance of the seismic joint itself

specific Embodiment approach

[0073] Specific implementation mode: A method for protecting adjacent buildings from swinging and damping. Seismic joints are arranged between adjacent buildings, and a shock-absorbing buffer device is arranged in the seismic joints to transform and dissipate the kinetic energy of the building's left and right swing. A separation structure is provided between the bases at both ends of the shock buffer device and the side walls of the building on both sides of the seismic joint, so that when the building on either side collapses and falls, the shock buffer device can rely on the separation structure and the side wall of the building to achieve separation.

[0074] In this way, the present invention can reduce the impact on the building by the provided shock absorption buffer device when the building is swayed from side to side due to earthquake or hurricane weather. At the same time, the disengagement mechanism is provided so that the shock-absorbing buffer device can not affect th...

Embodiment 1

[0077] In this embodiment, the method relies on Figure 1-4 The shock absorber shown is realized.

[0078] See Figure 1-4 , The shock-absorbing and buffering device of this embodiment includes two bases 2 installed on the side walls 1 of two adjacent buildings on both sides of the adjacent buildings, and a horizontal shock-absorbing spring 3 is arranged between the two bases 2 , Which also includes a sliding cylinder 4 and a sliding rod 5 arranged horizontally. The sliding cylinder 4 has a bottom end and an open end. One end of the sliding rod 5 is connected to a base, and the other end of the sliding rod 5 is slidably inserted and fitted. Insert the sliding cylinder into the open end of the sliding cylinder for a certain distance. The bottom end of the sliding cylinder 4 is connected to another base. The horizontal damping spring 3 is a coil spring and is installed inside the sliding cylinder 4. The bottom of the cylinder is fixedly connected, and the other end is fixedly conne...

Embodiment 2

[0110] In this example 2, the method relies on Figure 5-8 The shock absorber shown is realized.

[0111] See Figure 5-8 , The shock-absorbing and buffering device of this embodiment includes two bases 2 installed on the side walls 1 of the two adjacent buildings on the adjacent sides of the two adjacent buildings (that is, the side walls of the buildings on both sides of the seismic joint), and also includes internal threads The sleeve 3 and the screw 4 with external threads. The sleeve 3 and the screw 4 are arranged horizontally and each have a mating end and a mounting end connected to the base. The mating end of the screw 4 is inserted into the mating end of the sleeve 3. A certain distance and thread matching is realized, the mounting end of the sleeve 3 or the screw 4 and the base are rotatably connected, and the inclination angle of the thread slope of the external thread and the internal thread is greater than the friction angle.

[0112] In this way, when the building u...

Abstract

The invention discloses an anti-swinging damping protection method for adjacent buildings. Seismic joints are arranged between the adjacent buildings, and damping buffering devices are arranged in theseismic joints to convert and dissipate kinetic energy swinging left and right of the buildings. The anti-swinging damping protection method for the adjacent buildings is characterized in that separating structures are arranged between bases at the two ends of the damping buffering devices and building side walls of the two sides of the seismic joints, so that when any side of building collapsesand falls down, the damping buffering devices can be separated depending on the separating structures and the building side walls. The anti-swinging damping protection method for the adjacent buildings has the advantages that the damping buffering protection can be realized when the buildings swing left and right, meanwhile, it is ensured that the self functions of the seismic joints can be realized, and the influence on the adjacent buildings is reduced when the buildings collapse.

Description

Technical field [0001] The invention relates to the technical field of building earthquake resistance, in particular to a method for protecting adjacent buildings from swinging and damping. Background technique [0002] Seismic joints, also known as earthquake joints, refer to the structural joints between adjacent building units when designing and constructing houses. They are pre-set to reduce or prevent the collision of adjacent building structural units caused by earthquakes. gap. In order to prevent the building from being damaged by earthquakes, earthquake-proof joints are used to divide the building into several independent parts with simple shapes and uniform structural rigidity. [0003] However, after seismic joints separate the building into individual building units, the horizontal area of ​​a single building unit is small, its own stability is poor, and the anti-sway effect is reduced. Especially for some high-rise buildings, a single building unit is exposed to small...
