Description

Technical Field

[0001] The invention relates to the technical field of building exterior walls, and in particular to an inclined building exterior wall capable of recovering its function after wind vibration, a system and an installation method thereof. Background Art

[0002] Building exterior walls refer to components that maintain buildings and form boundaries between indoor and outdoor areas. Building exterior walls also have the function of bearing wind loads. Especially for high-rise or super-high-rise buildings, wind loads have a particularly significant effect on controlling the self-vibration of building structures. Current building exterior walls do not have a strong wind-vibration resistance function. If strong wind loads act on building exterior walls, not only will the building have a large self-vibration, but it will also endanger people's lives and property.

[0003] The restorable function is a new type of building form. It has been applied in the field of structural technology, but it is rarely applied in the field of building exterior walls. In addition, building technology is developing rapidly. In order to achieve the beauty of the building facade, it is necessary to set up exterior walls with various appearance forms, among which the inclined building exterior wall is the most widely used one. The inclined building exterior wall has a larger area affected by wind loads than the straight building exterior wall. The high-rise or super-high-rise buildings with inclined building exterior walls are more significantly affected by wind loads. Therefore, a kind of inclined building exterior wall with strong wind resistance and restorable function can be proposed, which is suitable for high-rise or super-high-rise buildings.

[0009] Preferably, a first slide track is provided on the inclined wall panel, and the first sliding block is engaged with the first slide track.

[0010] Preferably, a sliding connection plate is provided at one end of the distal connection member close to the inclined wall plate, the sliding connection plate is slidably hinged to the distal connection member, and the sliding connection plate is connected to the inclined wall plate via a fixing member.

[0012] The number of the rotating connecting rods is an even number. When there are two rotating connecting rods, a self-resetting device is provided between the two rotating connecting rods.

[0013] When the number of the rotating connecting rods is greater than two, a self-resetting device is provided between the two rotating connecting rods on both sides of the symmetry axis, and the rotating connecting rods on the same side of the symmetry axis are connected by a lightweight series rod.

[0014] Preferably, the rotatable connecting rod is rotatably connected to the outer wall through a fixed block.

[0015] Preferably, the self-resetting device is connected to the rotating connecting rod via a top cap.

[0016] A method for installing an inclined building exterior wall system capable of recovering its function after wind vibration, using the inclined building exterior wall system capable of recovering its function after wind vibration, comprising the following steps:

[0017] S1, first install the linkage device to a predetermined position on the outer wall, at which time the connecting arm is not connected to the first slider;

[0018] S2, sequentially installing the proximal connection structure and the distal connection member 5 on the outer wall 1;

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] The invention discloses an inclined building exterior wall capable of recovering its function after wind vibration. When the side of the inclined wall panel away from the exterior wall is subjected to wind vibration, the inclined wall panel approaches the exterior wall, and at this time, the end of the connecting arm connected to the inclined wall panel moves downward (refer to Figure 1 ), and drives the first slider to slide under the push of the inclined wall panel to protect the integrity of the inclined wall panel.

[0025] Furthermore, the proximal connection structure can not only realize the connection between the outer wall and the inclined wall panel, but also ensure a stable gap between the outer wall and the inclined wall panel. The proximal connection piece plays the role of connecting the rotating connecting rod and the outer wall.

[0026] The distal connector can increase the stability and safety of the inclined wall plate when it approaches the outer wall. When the inclined wall plate approaches the outer wall, one end of the distal connector connected to the inclined wall plate slides along the longitudinal axis of the distal connector.

[0027] Furthermore, the second sliding block and the second slideway cooperate with each other, which helps the inclined wall panel to stably approach the outer wall when subjected to wind vibration.

[0028] Furthermore, the first slideway and the first sliding block cooperate with each other, which helps to ensure stable connection and sliding of the inclined wall panel and the outer wall.

[0029] In the present invention, a slanted building exterior wall system capable of recovering function after wind vibration realizes linkage and unification of the entire system by rotating connecting rods, self-resetting devices and light series rods, which can balance wind loads and make each slanted wall panel produce the same movement trend, and can greatly reduce the impact of wind loads on high-rise or super high-rise buildings. When the slanted wall panel is subjected to wind load, the slanted wall panel has a tendency to rotate, and because the slanted wall panel is symmetrically arranged, with the axis of symmetry as the dividing line, the rotation trend direction of the slanted wall panel is opposite, and at this time the self-resetting device is pulled and consumes energy, so that the slanted wall panel has a tendency to recover the rotation trend.

[0030] The light series rod can connect multiple inclined panels on both sides of the symmetry axis in series, so that the multiple inclined panels have the same rotation tendency. BRIEF DESCRIPTION OF THE DRAWINGS
