Abstract

This invention relates to the field of seismic resistance technology for building structures, specifically to a retractable facade enclosure device and structure for building seismic isolation joints, comprising a fence and tubular components. The tubular components are symmetrically arranged, with the fence connecting two symmetrically arranged tubular components to form a vertical planar device. This vertical planar device is used to connect with building components. The fence can fold and slide in the vertical plane, along its length and height.

Description

Technical Field

[0001] This invention relates to the field of seismic resistance technology for building structures, specifically to a retractable facade enclosure device and enclosure structure for building seismic isolation joints. Background Technology

[0002] Earthquake damage indicates that the primary cause of casualties and economic losses in earthquakes is the collapse and destruction of buildings. Seismic isolation technology is currently one of the most effective techniques for enhancing the seismic performance of building structures and mitigating earthquake damage. In buildings employing seismic isolation technology, the reserved space through seismic isolation joints ensures the normal functioning of the isolated structure during an earthquake. However, earthquake damage results show that, especially in seismically isolated buildings in medium- to high-intensity seismic zones, the building envelope or protective measures on both sides of the seismic isolation joints have many problems that affect the normal seismic performance of the isolated structure.

[0003] Firstly, the large width of seismic isolation joints currently leads to insufficient lateral bearing capacity of the building envelope or protective measures on the sides of passageways crossing them. This is because there are currently no specific atlases for designing the building envelope on the sides of passageways crossing seismic isolation joints; designers are forced to rely on existing building expansion joint atlases. However, the maximum applicable joint width in these atlases is only 300mm, while in seismic isolation buildings in medium- and high-intensity seismic zones, the joint width can reach 800mm or more. The continued application of these atlases or modifications during design phases results in insufficient lateral bearing capacity of the building envelope on the sides of the seismic isolation joints due to the increased span.

[0004] Secondly, during an earthquake, the building maintenance or protective measures on both sides of the seismic isolation joint may be damaged, either on their own or along with other components, causing the seismic isolation joint to become blocked and unable to move freely. Consequently, the seismic isolation structure cannot deform normally, leading to damage and destruction of the superstructure. At the same time, an earthquake can prevent people from escaping in time while crossing the seismic isolation joint, seriously endangering their personal safety. Summary of the Invention

[0005] The purpose of this invention is to provide a retractable facade enclosure device and enclosure structure for building seismic isolation joints. The device can generate expansion, contraction, and sliding deformation in the vertical plane, and rotational deformation outside the vertical plane, and can move freely in three directions. The device is fixed on the building components on both sides of the seismic isolation joint and can be used as a seismic expansion device for the side of passages or the exterior facade of buildings that span different widths of the seismic isolation joint. It can solve the problem that the seismic isolation structure cannot deform normally because the building components on both sides of the seismic isolation joint are damaged during an earthquake and cannot move freely.

[0006] This invention is achieved through the following technical solution:

[0007] A retractable facade enclosure for building seismic isolation joints, comprising a fence and a tube;

[0008] The pipes are arranged symmetrically, and a fence is connected between the two symmetrically arranged pipes to form a vertical planar device, which is used to connect with building components.

[0009] The fence can be folded and slid in the vertical plane, along the length and height. The rotatable joints at both ends of the fence are set in two tubes, and the plane on which the fence is located can be made vertical or inclined by rotation.

[0010] The slippage described in this invention refers to axial movement under seismic action; the length direction of the fence specifically refers to the width direction of the gap between the two pipes, and the height direction of the fence specifically refers to the axial direction of the pipes.

[0011] The fence of this invention can fold and slide in its length and height directions in the vertical plane. The rotating shafts at both ends of the fence are respectively set in two tubes, realizing the three-way free displacement and automatic reset of the fence. This avoids the problem of collision between adjacent building units or units on both sides of the expansion joint due to excessive deformation. Since the fence of this invention can fold and slide in its length and height directions in the vertical plane, that is, the fence can expand and contract in its length direction, it can adapt to vertical expansion joints of different widths. Furthermore, due to the three-way free displacement and automatic reset of the fence, the entire enclosure device for building adaptive seismic isolation joint facade deformation has a large load-bearing capacity.

[0012] Furthermore, the fence between the two pipes includes at least one of a segmented fence and a monolithic fence;

[0013] The segmented fence includes multiple independent telescopic units arranged in parallel from top to bottom, or the segmented fence includes multiple independent telescopic components arranged in parallel from top to bottom, each telescopic component including at least two telescopic units arranged in parallel from top to bottom, and adjacent telescopic units in each telescopic component are hinged to each other to enable the telescopic component to fold and slide in its height direction.

[0014] The integral fence includes multiple telescopic units arranged in parallel from top to bottom, with adjacent telescopic units hinged to each other to enable the integral fence to fold and slide in its height direction.

[0015] Furthermore, the telescopic unit is composed of several rhomboid units connected in series, with adjacent rhomboid units hinged to each other to enable the telescopic unit to fold and slide in its length direction; the four sides of the rhomboid unit are hinged to each other.

[0016] Furthermore, the two adjacent rhomboid units are detachably connected to allow for adjustable length of the telescopic unit.

[0017] Furthermore, all hinges are connected using pins.

[0018] Furthermore, a rotating shaft joint is provided inside the tube. Both ends of the fence are connected to the rotating shaft joint by screws. One end of the screw is hinged to the fence, and the other end is threaded to the rotating shaft joint.

[0019] Furthermore, a limiting plate is provided inside the tube, which is used to limit the downward movement of the fence in the axial direction of the tube.

[0020] Furthermore, a fan-shaped notch is provided on the side wall of the tube.

[0021] Furthermore, the fence is connected to a corrugated cover plate on at least one side, the corrugated cover plate being foldable and sliding along its length. The corrugated cover plate is equivalent to a corrugated flexible surface, which can be used to protect the fence without affecting the folding and sliding of the fence.

[0022] A seismic isolation building includes a facade seismic expansion joint as described above, and also includes building components; the tube is connected to the building components via pre-embedded anchor bolts.

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

[0024] This invention relates to a fence that can fold and slide in its length and height directions in a vertical plane. The rotating joints at both ends of the fence are respectively housed within two tubular sections, enabling three-way free displacement and automatic repositioning. This not only prevents collisions between adjacent building units or units on both sides of an expansion joint due to excessive deformation, but also gives the entire retractable facade enclosure device for building seismic isolation joints a greater load-bearing capacity. Furthermore, because the fence can fold and slide in its length and height directions in a vertical plane, meaning it can expand and contract along its length, it can adapt to vertical expansion joints of different widths. It is suitable for seismic expansion and contraction of joints with different spans, and simultaneously solves the problem of seismic isolation joints or trenches being blocked during earthquakes, preventing free displacement and thus hindering the normal deformation of the seismic isolation layer. Additionally, this retractable facade enclosure device for building seismic isolation joints can also serve as a lateral fence, ensuring the safety of life and property. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0035] Example 1:

[0036] like Figures 1-6 As shown, a retractable facade enclosure device for building seismic isolation joints includes a fence 3 and a tube 2.

[0037] Two pipes 2 are symmetrically arranged, forming a vertical plane between the two pipes 2. The pipes 2 are used to connect with building components 8, which include shear walls, wall columns or beams.

[0038] The fence 3 can fold and slide in its length and height directions in the vertical plane, that is, the fence 3 can be extended and retracted in both length and height directions to meet the seismic requirements. The rotating shafts 6 at both ends of the fence 3 are respectively set in the two tubes 2. By rotating, the plane on which the fence 3 is located can be a vertical plane or an inclined plane. That is, the fence 3 can slide and fold in its plane and rotate outside the plane to meet the seismic requirements.

[0039] The fence 3 described in this embodiment can fold and slide in its length and height directions in the vertical plane. The rotating shafts 6 at both ends of the fence 3 are respectively set in the two tubes 2, realizing the three-way free displacement and automatic reset of the fence 3. This not only avoids the problem of collision between adjacent building units or units on both sides of the expansion joint due to excessive deformation, but also makes the entire facade seismic expansion joint device have a large load-bearing capacity. Moreover, since the fence 3 of this invention can fold and slide in its length and height directions in the vertical plane, that is, the fence 3 can expand and contract in its length direction, it can adapt to vertical expansion joints of different widths. It can be applied to seismic expansion joints of different span widths, and at the same time, it can solve the problem that the seismic isolation joint or seismic isolation trench cannot be freely displaced during an earthquake, resulting in the seismic isolation layer of the seismic isolation structure not being able to deform normally. At the same time, this retractable facade enclosure device can also serve as a lateral fence to ensure the safety of life and property.

[0040] Specifically, the fence 3 between the two pipes 2 includes at least one of segmented fence and integral fence, that is, the fence 3 can be a segmented fence or an integral fence.

[0041] like Figure 3 As shown, the segmented fence includes multiple independent telescopic units arranged in parallel from top to bottom, or the segmented fence includes multiple independent telescopic components arranged in parallel from top to bottom. Each telescopic component includes at least two telescopic units arranged in parallel from top to bottom, and adjacent telescopic units in each telescopic component are hinged to each other to enable the telescopic component to fold and slide in its height direction.

[0042] like Figure 4 The integral fence includes multiple telescopic units arranged in parallel from top to bottom, with adjacent telescopic units hinged to each other to enable the integral fence to fold and slide in its height direction.

[0043] The overall height of fence 3 can be adjusted by setting the number of telescopic units.

[0044] The telescopic unit is composed of several diamond-shaped units connected in series. Adjacent diamond-shaped units are hinged to each other to allow the telescopic unit to fold and slide along its length. The four sides of the diamond-shaped units are hinged to each other. All hinges are connected by pins 7, which can be used to increase or decrease the length of the fence 3.

[0045] In a preferred embodiment, there is a detachable connection between two adjacent rhomboid units to allow for adjustable length of the telescopic unit. The detachable connection can be made via a pin 7.

[0046] In a specific implementation scheme, such as Figure 1As shown, a segmented fence is installed between the two pipes 2. The segmented fence consists of three telescopic components, each of which consists of two telescopic units.

[0047] In one specific implementation scheme, the rotation of fence 3 is achieved as follows:

[0048] A rotating joint 6 is installed inside the tube 2. Both ends of the fence 3 are connected to the rotating joint 6 via screws 5. One end of the screw 5 is hinged to the fence 3, and the other end is threaded to the rotating joint 6. Specifically, one end of the screw 5 is a hole, and the other end is a thread. The screw 5 acts as a support for the fence 3, allowing the fence 3 to fold and deform between supports, thus meeting the deformation requirements under seismic loads. The screw 5 and the rotating joint 6 are connected by threads to form a single unit, which is placed inside the tube 2.

[0049] Specifically, the tube is hollow to ensure that the fence 3 slides in the axial direction of the tube 2; an opening is provided on the inner side of the tube 2 or multiple through slots are provided on the inner side of the sliding tube 2. The opening or through slots are used to pass through the screw 5 and enable the screw 5 to slide in the axial direction of the tube 2. The inner side of the tube 2 specifically refers to the side of the two tubes 2 facing each other.

[0050] In a preferred embodiment, a fan-shaped notch is provided on the side wall of the tube 2. The tube 2 has a fan-shaped notch with the plane of the fence 3 as the axis, which can ensure that the fence 3 can rotate out of the plane to meet the deformation requirements of multiple directions during earthquakes.

[0051] In a preferred embodiment, a limiting piece is provided on one side inside the tube 2 to ensure that the fence 3 slides in the axial direction of the tube 2 without falling; that is, the limiting piece is used to limit the downward movement of the fence 3 in the axial direction of the tube 2.

[0052] In a specific implementation scheme, such as Figure 1 As shown, a segmented fence is set between the two tubes 2. The segmented fence consists of three telescopic components. Each telescopic component consists of two telescopic units, and each telescopic unit has a screw 5 at both ends. The screw 5 and the rotating shaft 6 are connected by threads to form a whole and are placed inside the tube 2.

[0053] In a preferred embodiment, the fence 3 is connected to a corrugated cover plate 4 on at least one side. The corrugated cover plate 4 is foldable and slideable along its length. The corrugated cover plate is essentially a flexible corrugated surface that protects the fence without affecting its folding and sliding. The corrugated cover plate 4 is connected to the fence 3 by adhesive or spot welding to form a whole. The whole structure can meet the deformation requirements in multiple directions under seismic loading.

[0054] In this embodiment, the telescopic unit is connected by a pin 7 to form an in-plane rhomboid unit and an out-of-plane hinged waveform flexible surface. The tube 2 is connected to the built-in rotating shaft 6 and is connected to the telescopic unit through a screw 5 to form an integrated system. This mainly solves the problems of small displacement, poor bearing capacity, and inability to adapt to large deformations in multiple directions in seismic isolation buildings.

[0055] Example 2:

[0056] An enclosure structure for a seismic isolation building facade includes a retractable facade enclosure device as described in Embodiment 1, and also includes building components 8; the building components 8 are arranged in pairs, and a vertical expansion joint is formed between the two building components 8; the retractable facade enclosure device described in Embodiment 1 is placed in the vertical expansion joint; the pipe 2 is connected to the building components 8 through pre-embedded anchor bolts 1; the building components 8 include wall columns or beams, specifically structural shear walls or structural columns.

[0057] The enclosure structure described in this embodiment can enable the building component 8 to deform both inside and outside the plane while avoiding collision damage.
