Description

Technical Field

[0001] The invention relates to the technical field of building glass curtain walls, and in particular to a design method for a ternary integrated shutter system of a curtain wall of a refuge layer of a high-rise building. Background Art

[0002] According to the Code for Fire Protection Design of Buildings (GB 50016-2014), public buildings with a building height of more than 100 meters must be equipped with a refuge floor, and such a refuge floor can also serve as an equipment floor. Specifically, the vertical distance from the floor of the first refuge floor to the ground of the fire-fighting and rescue site shall not exceed 50 meters, and the interval height between two adjacent refuge floors is recommended not to exceed 50 meters.

[0003] In practical applications, the refuge floor not only bears the function of emergency evacuation, but is also often used as an equipment floor in high-rise buildings. The equipment floor refers specifically to a specific floor in a high-rise building, and its effective area is mainly or entirely used to arrange facilities such as air conditioning, water supply and drainage, electrical and elevator rooms. Given the large demand for equipment space in high-rise buildings, usually more than 50% of the area of ​​the refuge floor is planned as equipment space.

[0004] In the design process of high-rise buildings, it is necessary to comprehensively consider the emergency evacuation needs, the functions of the fresh air system required by the equipment, and the reflective characteristics. Traditional designs often focus on showing the regularity of the refuge layer itself, such as the practice of Guangzhou International Finance Center, but such designs often ignore the consistency with the overall curtain wall style of the building, resulting in deficiencies in the reflective characteristics of the building.

[0005] For example, the traditional aluminum alloy louver system, as a common material for the current shelter design, has limitations in both visual and performance. The material reflectivity is significantly different from that of the glass curtain wall, resulting in a lack of continuity in the reflective properties of the building facade, affecting the overall reflective effect of the building. In addition, the system's performance in ventilation efficiency and waterproof performance is also unsatisfactory, especially in high-rise buildings.

[0006] In view of the above problems, we propose a three-component integrated shutter system design method for the curtain wall of the refuge layer of high-rise buildings to solve the above technical problems. Summary of the invention

[0007] In view of the problems existing in the above-mentioned prior art, the present invention provides a three-component integrated louver system design method for the curtain wall of the refuge floor of a high-rise building, which weakens the spatial characteristics of the refuge floor and emphasizes the integrity of the building form through similar processing methods. On this basis, a three-component integrated system combining two layers of glass louvers and one layer of rainproof louvers is designed to ensure that the facade presents a reflective property similar to that of the glass curtain wall, so that the overall facade of the high-rise building appears more coordinated and unified. At the same time, it fully meets the strict requirements of the refuge floor equipment area for complex ventilation and waterproofing technology.

[0008] In order to achieve the above object, the present invention adopts a three-element integrated louver system design method for a high-rise building refuge layer curtain wall, comprising the following steps:

[0009] Step 1: Install the first glass louver on the outer facade of the refuge layer;

[0010] Step 2: Install a second glass louver behind the opening of the refuge floor;

[0011] Step 3: Install rainproof louvers between the second glass louver and the equipment room; where:

[0012] The first glass louvers and the second glass louvers are arranged alternately.

[0013] As a further optimization of the above solution, the first glass louver is made of the same material as the outer glass curtain wall of the building.

[0014] As a further optimization of the above solution, the first layer of shutters is arranged parallel to the floor slab, and the second layer of shutters is fixed on the additional structure between the columns.

[0015] As a further optimization of the above solution, a buffer space is provided between the second layer of glass louvers and the rainproof louvers, and a floor drain is provided in the buffer space.

[0016] The above method weakens the spatial characteristics of the refuge floor and emphasizes the integrity of the building form through similar treatment methods. On this basis, a three-element integrated system combining two layers of glass louvers and one layer of rainproof louvers is designed to ensure that the facade presents a reflective property similar to that of the glass curtain wall, making the overall facade of the high-rise building more coordinated and unified. At the same time, it fully meets the strict requirements of the equipment area of ​​the refuge floor for complex ventilation and waterproofing technology.

[0017] As a further optimization of the above solution, the first glass louver has a recessed area, wherein:

[0018] The recessed area is located at two sides of the refuge layer. In the recessed area, a first spacing between two adjacent first louver units in the first glass louver is greater than a second spacing between two adjacent second louver units in the facade texture area.

[0019] For super high-rise buildings such as the main tower of Wuhan Greenland Center, the soft rounded corners on both sides of the refuge floor are used to reduce the wind resistance and vortex phenomenon around the high-rise building. This can effectively reduce the amount of structural materials required during the construction process, thereby achieving cost optimization. At the same time, the specially designed concave area also plays a role in reducing the structural wind load caused by the shedding of wind vortices, further improving the overall stability and safety of the building.

[0020] As a further optimization of the above solution, the first glass louver also has a facade texture area, the first glass louver in the recessed area is horizontal, and the first glass louver in the recessed area is arranged in parallel with the first glass louver in the facade texture area, and the facade texture area is cleverly formed in the middle of the refuge floor, which effectively reduces the impact of external wind pressure on the middle area of ​​the refuge floor, thereby improving the comfort and safety of the refuge floor during use.

[0021] As a further optimization of the above solution, the flipping angles of two adjacent second louver units are different, thus forming a wavy facade texture effect.

[0022] As a further optimization of the above scheme, the flip mechanism is used to realize the dynamic wave-like adjustment of the second louver unit, thereby significantly improving the reflective effect of the building. In addition, by adjusting the angle of the louver in real time, the internal airflow reception situation is effectively changed, and the indoor air is flexibly adjusted to ensure that the air quality of the internal space of the refuge floor better meets the use requirements. The specific details are as follows:

[0023] The facade texture area includes a plurality of flipping mechanisms arranged in sequence, the flipping mechanisms include fixed frames arranged at equal intervals, the second louver unit is installed on the fixed frames, and the driving assembly provides power for the second louver unit and drives the second louver unit to flip;

[0024] The driving assembly comprises two rotating shafts respectively passing through the two ends of the second louver unit in the length direction, a half gear is installed at one end of the rotating shaft, and the two half gears are arranged on the same side, a cylinder is installed at one end of the fixed frame, the output end of the cylinder is connected to a driving gas rod, a connecting frame is connected to the driving gas rod, and both ends of the connecting frame are connected to connecting plates, and both ends of the connecting plate are provided with a first tooth plate and a second tooth plate meshing with the half gears, and when the first tooth plate meshes with one of the half gears, the second tooth plate is in a non-meshing state with the other half gear;

[0025] The connecting frame is also provided with two limit frames, the fixed frame is provided with a placement slot for placing the rotating shaft, a fixed block is provided on the side of the placement slot, a limit hole is provided on the fixed block, the limit frame is provided with a limit block passing through the limit hole, and the top surface of the placement slot is located on the moving path of the limit block.

[0026] The three-element integrated louver system design method of the high-rise building refuge layer curtain wall of the present invention has the following beneficial effects:

[0027] 1. The three-component integrated louver system design method of the curtain wall of the refuge layer of a high-rise building of the present invention adopts a similar design method to weaken the characteristics of the refuge layer in order to highlight the integrity of the entire building. It incorporates a three-component integrated system consisting of two layers of glass louvers and one layer of rainproof louvers to ensure that the reflective characteristics of the facade are coordinated with the glass curtain wall, making the facade of the high-rise building more harmonious. In addition, the design effectively meets the needs of the equipment area of ​​the refuge layer for complex ventilation and waterproofing technology.

[0028] 2. The three-element integrated louver system design method of the curtain wall of the refuge layer of a high-rise building of the present invention is to reduce the wind resistance and vortex influence around the high-rise building, and the two sides of the refuge layer are designed with soft rounded corners, which significantly reduces the structural materials required for construction and helps cost control. In addition, the specially designed recessed area can add architectural features and effectively reduce the structural wind load caused by wind vortex shedding, thereby enhancing the overall stability and safety of the building.

[0029] 3. The three-element integrated louver system design method for the curtain wall of the refuge floor of a high-rise building of the present invention creates a unique facade texture area in the middle of the refuge floor, greatly enriching the appearance level of the building.

[0030] 4. In addition, the present invention also cleverly reduces the impact of external wind pressure on the middle part of the refuge layer, making the refuge layer more comfortable and safer when in use.

[0031] 5. The present invention provides a three-component integrated louver system design method for the curtain wall of a refuge layer of a high-rise building. Through the flipping mechanism, the second louver unit realizes dynamic wave-like adjustment, which significantly enhances the reflective effect of the building's exterior. At the same time, the flipping structure adjusts the louver angle in real time, flexibly adjusts the internal airflow reception, and thus effectively regulates the indoor air, so that the air quality inside the refuge layer better meets the use requirements.

The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0044] Please refer to the instruction manual Figure 1-7 The present invention provides a first embodiment of a three-element integrated louver system design method for a high-rise building refuge layer curtain wall, comprising the following steps:

[0045] Step 1: Install the first glass louver 1 on the outer facade of the refuge layer;

[0046] Step 2: Install a second glass shutter 2 at the rear side of the refuge floor opening;

[0047] Step 3: Install rainproof louvers 3 between the second glass louvers 2 and the equipment room; wherein:

[0048] The first glass louver 1 and the second glass louver 2 are arranged alternately. The first glass louver 1 is made of the same material as the glass curtain wall 4 outside the building. The first layer of louvers is arranged parallel to the floor slab, and the second layer of louvers is fixed on the additional structure between the columns. A buffer space is provided between the second layer of glass louvers and the rainproof louvers 3, and a floor drain is provided in the buffer space.

[0049] It should be noted that the electromechanical equipment 5 is arranged behind the waterproof louver. At the same time, the effective ventilation volume of the three-element integrated glass louver system is designed to be no less than the ventilation volume required by the equipment room. In the specific implementation, the opening height of the first layer of glass louvers and the spacing between the first layer of glass louvers and the second layer of glass louvers can be adjusted to meet the actual ventilation volume requirements.

[0050] It is further explained that the first layer of blinds and the second layer of blinds are staggered, and the glass blinds and the glass on the facade have the same reflectivity. Although the second layer of glass blinds is relatively darker than the first layer of blinds, it can still achieve a good reflective effect overall.

[0051] Please refer to the instruction manual Figure 1-7 The present invention provides a second embodiment of a ternary integrated louver system design method for a high-rise building refuge layer curtain wall. On the basis of the implementation steps of the first embodiment, the second glass louver 2 can be adjusted to an overall design and moved backward as a whole based on the premise that the space is relatively abundant. Under this design concept, the second glass louver 2 adopts relatively large glass louvers, and the ventilation spacing is relatively enlarged, which is convenient for the installation and maintenance of the second glass louver 2.

[0052] Please refer to the instruction manual Figure 1-7The present invention provides a third embodiment of a three-element integrated louver system design method for a high-rise building refuge layer curtain wall. Based on the above first embodiment, this embodiment refers to the high-rise building method of Debis Building and Wuhan Greenland Center, performs a softening fillet treatment on the refuge layer, and specifically forms a wind trough-like structure. Specifically, a recessed area 11 is designed on the first glass louver 1, and the recessed area 11 is located at two edge parts of the refuge layer. In this recessed area 11, the first spacing 111 between two adjacent first louver units in the first glass louver 1 is greater than the second spacing 121 between two adjacent second louver units in the facade texture area 12.

[0053] The design of the recessed area 11 is aimed at dealing with the wind resistance effect and vortex phenomenon that are prone to occur around high-rise buildings. To achieve this goal, both sides of the refuge layer are given a soft rounded corner treatment. This design strategy not only helps to reduce the required structural materials during the construction process and achieve the purpose of cost optimization, but also the unique structure of the recessed area 11 can effectively alleviate the structural wind load caused by the shedding of wind vortices, thereby significantly improving the overall stability and safety of the building.

[0054] Please refer to the instruction manual Figure 1-7 The present invention provides a fourth embodiment of a three-element integrated louver system design method for a high-rise building refuge layer curtain wall, wherein the first glass louver 1 also has a facade texture area 12, the first glass louver 1 in the recessed area 11 is horizontal, and the first glass louver 1 in the facade texture area 12 is horizontal, and at the same time, the facade texture area 12 is cleverly formed in the middle of the refuge layer. The appearance expression of the building is effectively enriched, and the influence of external wind pressure on the middle area of ​​the refuge layer is effectively reduced, thereby improving the comfort and safety of the refuge layer during use.

[0055] As a further optimization of the above solution, the flipping angles of two adjacent second louver units are different, thereby forming a wavy facade texture effect and optimizing the reflective effect of the refuge layer of the high-rise building.

[0056] As a further optimization of the above scheme, the flip mechanism 6 is used to realize dynamic wave-like adjustment of the second louver unit, thereby significantly improving the reflective effect of the building appearance, and by adjusting the angle of the louver in real time, the internal airflow reception situation is effectively changed, thereby flexibly adjusting the indoor air to ensure that the air quality of the internal space of the refuge floor better meets the use requirements. The specific details are as follows:

[0057] The facade texture area 12 includes a plurality of flipping mechanisms 6 arranged in sequence, and the flipping mechanism 6 includes fixed frames 61 arranged at equal intervals, the second louver unit is installed on the fixed frames 61, and the driving component provides power for the second louver unit and drives the second louver unit to flip;

[0058] The driving assembly includes two rotating shafts 62 respectively passing through the two ends of the second louver unit in the length direction, a half gear 63 is installed at one end of the rotating shaft 62, and the two half gears 63 are arranged on the same side, a cylinder 64 is installed at one end of the fixing frame 61, and a driving gas rod 65 is connected to the output end of the cylinder 64, a connecting frame 66 is connected to the driving gas rod 65, and both ends of the connecting frame 66 are connected to connecting plates 67, and both ends of the connecting plate 67 are provided with a first tooth plate 671 and a second tooth plate 672 meshing with the half gear 63, when the first tooth plate 671 is meshing with one half gear 63, the second tooth plate 672 is in a non-meshing state with the other half gear 63;

[0059] The connecting frame 66 is also provided with two limit frames 673, the fixed frame 61 is provided with a placement slot 611 for placing the rotating shaft 62, a fixed block 612 is provided on the side of the placement slot 611, a limit hole 613 is provided on the fixed block 612, and the limit frame 673 is provided with a limit block 674 passing through the limit hole 613, and the top surface of the placement slot 611 is located on the moving path of the limit block 674.

[0060] The working steps of the above-mentioned turning mechanism 6 are as follows:

[0061] The above-mentioned cylinder 64 causes the driving air rod 65 to move forward, thereby driving the rack to start moving, and the teeth on the rack mesh with one of the half gears 63 fixed on the object to be flipped. As the rack moves, the half gear 63 starts to rotate, and the rotation of the gear drives the object to be flipped to rotate around its fixed axis until it reaches the target position of 90 degrees. The above-mentioned cylinder 64 causes the driving air rod 65 to move in the opposite direction, thereby driving the rack to move in the opposite direction, and the teeth on the rack mesh with the other half gear 63 fixed on the object to be flipped. As the rack moves, the half gear 63 starts to rotate, and the rotation of the gear drives the object to be flipped to rotate around its fixed axis until it reaches the target position of -90 degrees, thereby achieving ±90 degree flipping for the second louver unit.
