Description

Technical Field

[0001] The present invention relates to the field of high-rise buildings, and in particular to a method for reducing the common area of ​​super-high-rise residential buildings. Background Art

[0002] With the acceleration of urbanization and the continuous advancement of construction technology, super-high-rise residential buildings have become a vital component of modern cities due to their unique role in conserving urban land, enhancing urban image, and promoting social investment. The core tube design of these high-rise buildings is particularly critical. It not only carries out transportation and evacuation functions but also directly affects the building's structural safety. In the actual design process, factors such as earthquake and wind loads must be considered to determine the shape and size of the core tube. Due to the height of super-high-rise residential buildings, the seismic and wind loads are greater, necessitating a larger core tube to meet the structural lateral stiffness and ensure building stability. However, in architectural plan design, after the necessary vertical transportation facilities and ducts are arranged within the core tube, a large amount of unused space is often left. The current common approach to addressing this unused space within the core tube is to add elevators or increase the size of the ducts. While this approach can fill the remaining space, it increases the building's common area and reduces the actual floor space ratio for residents. Summary of the Invention

[0003] The present invention aims to provide a method for reducing the common area of ​​super high-rise residential buildings, so as to reduce the common area of ​​super high-rise residential buildings and improve the actual housing ratio of residents.

[0004] To achieve the above-mentioned object, the present invention adopts the following technical solution: a method for reducing the common area of ​​a super-high-rise residential building, comprising the following steps: first, obtaining super-high-rise building information, calculating the structural parameters of the main building structure based on the super-high-rise building information, obtaining the core tube size of the super-high-rise building, and determining the position and size of the holes that can be opened on each side of the core tube according to the principle of opening holes in the outer wall of the core tube;

[0005] The second step is to centrally arrange pipe shafts and traffic facilities in the core tube, dividing the core tube into common space and remaining space through the centralized arrangement of pipe shafts and traffic facilities. The pipe shafts and traffic are centrally arranged in the common space.

[0006] The third step is to incorporate the remaining space into the residential space for planning, and according to the opening principle, open corresponding holes on the outer wall of the core tube to connect the remaining space with the residential space.

[0007] Generally speaking, in order to ensure the lateral rigidity of super high-rise buildings, excluding necessary ingress and egress passages, the integrity of the outer wall of the core tube needs to be ensured to provide sufficient lateral rigidity. When holes are punched in the outer wall of the core tube, the integrity of the outer wall of the core tube will inevitably be affected. For the space inside the core tube, only public equipment such as elevators or pipe shafts can be installed, thereby dividing the space inside the core tube into common space. However, if the elevators are reasonably arranged based on the number of residents and the carrying capacity of the elevators, there is still a lot of space left in the core tube. The inventor found through statistics in the actual work process that after the elevators, stairs and pipe shafts are reasonably arranged in the core tube, the remaining space is about 3-9% of the building floor area. In order to reasonably plan the remaining space, there are two existing solutions. One is to increase the number of elevators or increase the size of the pipe shaft as mentioned in the background technology, and fill the remaining space with public space. Filling the space inside the core tube seems to make full use of the space inside the core tube, but too many elevators will cause a series of problems such as excess capacity, increased energy consumption, and increased maintenance costs. Similarly, simply increasing the size of the pipe shaft will also cause problems such as space waste and increased costs. At the same time, larger pipe shafts are more likely to transmit noise and vibration, affecting the comfort of residents; another way is to knock out the floor slabs in the remaining space after laying out the pipe shafts, stairs and elevators to form a structure similar to a patio. On the one hand, it enhances the lighting of residents near the core tube and reduces the common area of ​​the building to a certain extent. However, it fails to achieve efficient use of land resources and also brings some other problems. For example, the holes in the floor slabs form a chimney effect, which is not conducive to building fire protection. In addition, the holes in the floor slabs reduce the lateral constraints of the core tube, which reduces the safety of the core tube to a certain extent.

[0008] The beneficial effects of this scheme are as follows: this scheme increases the utilization rate of the space inside the core tube by dividing the internal space of the core tube into residential space, thereby reducing the common area ratio of super-high-rise residential buildings. At the same time, according to the principle of opening holes in the outer wall of the core tube, the remaining space is connected with the residential space, reducing the impact of the openings in the outer wall of the core tube on the structural strength of the core tube.

[0009] In addition, the solution of the present application can utilize the remaining space of the core tube. Therefore, without affecting the necessary vertical traffic and pipeline well layout, the size of the core tube can be flexibly adjusted to achieve the optimal structural seismic performance and the best structural economy.

[0010] At the same time, by effectively utilizing the remaining space, the space utilization rate of the entire building is improved and the usable area is increased. The solution of this application determines the size of the core tube of the super high-rise building and the opening position of the outer wall of the core tube through computer simulation. After arranging the necessary vertical traffic and pipeline wells in the core tube, the remaining space in the core tube is efficiently utilized. The proportion of indoor space arranged using the remaining space of the core tube reaches 17%-40%, which significantly increases the usable area of ​​super high-rise residential buildings, reduces the common area ratio of standard floors by about 3%-9%, greatly improves the building economy, and realizes the efficient use of land resources.

[0011] Furthermore, the principle of opening holes is: measured from the inside of the core tube, the distance between the opening position on the outer wall of the core tube and the corner is greater than or equal to 50 cm, and the number of holes on the outer wall of the same core tube is less than or equal to two. When the number of holes is two, the wall distance between the two holes is not less than 120 cm.

[0012] Measured from the core tube, the distance between the core tube's exterior wall openings and corners should be at least 50 cm. This principle ensures that the core tube's structural integrity is not affected by the openings. A distance of at least 50 cm from corners helps prevent stress concentration caused by the openings, thereby reducing the risk of cracks.

[0013] The number of openings in the exterior wall of a core tube should be no more than two; limiting the number of openings can reduce damage to the core tube's structural integrity. Each opening weakens the continuity and rigidity of the wall, so limiting the number of openings helps maintain the overall stability and safety of the structure.

[0014] When there are two openings, the wall distance between the two holes should not be less than 120 cm: this principle ensures that even if there are two openings, there is sufficient wall support between them to maintain the stability of the wall. The distance between holes of more than 120 cm helps to distribute the load, reduce stress concentration, and thus reduce the risk of wall cracking.

[0015] Beneficial effect: By limiting the location and number of openings, the impact of openings on the core tube's exterior wall on the core tube's structural strength is reduced.

[0016] Furthermore, the super-high-rise building information collected in the first step includes information such as building layout, external dimensions, floor height and total height. The calculation method is: a structural finite element model is established through the collected information, and the structural finite element model is input into the structural calculation software. The structural parameters of the main body of the building structure are calculated through simulation to determine the core tube size.

[0017] Beneficial effects: A structural finite element model is established based on information such as building layout, external dimensions, floor height and total height, and the structural finite element model is input into structural calculation software. The structural parameters of the main body of the building structure are calculated through simulation to determine the core tube size, thereby obtaining a core tube size with optimal seismic performance.

[0018] Furthermore, the transportation facilities include horizontal transportation and vertical transportation. The horizontal transportation includes walkways, and the vertical transportation includes stairs and public elevators. The walkways are arranged around the vertical transportation, so as to facilitate entering and exiting the elevator room of the building and entering the residence.

[0019] Furthermore, the walking stairs are scissor stairs, and the scissor stairs and public elevators are arranged centrally.

[0020] Beneficial effects: The walking stairs are set as scissor stairs and arranged centrally with the public elevator, thereby reducing the floor space and the common area. At the same time, there is no need to add elevators or expand the size of the pipe shaft to fill the core tube.

[0021] Furthermore, in the third step, during planning, it is necessary to set up a partition wall or entrance door to separate the remaining space in the core tube from the common space.

[0022] Beneficial effect: By setting up openings and partition walls, the remaining space is connected to the residential space to form an integrated residential space, thereby reducing the impact of the remaining space in the core tube on the housing ratio of residents.

[0023] Furthermore, the remaining space in the core tube can be used to arrange secondary functional rooms, which are one or more rooms with lower lighting requirements such as bathrooms, kitchens, private elevators, entrance halls, storage rooms or cloakrooms.

[0024] Beneficial effects: 1. When designing the core tube, the location of these spaces can be planned in advance so that the corresponding space can be reserved during the construction process; 2. Arranging these rooms in the core tube can increase privacy, especially in apartments or residential buildings; 3. By using part of the core tube's exterior wall as the residential wall, the demand for residential wall construction can be reduced, thereby saving construction materials and costs; 4. Through clever design, these spaces can be made more practical, meeting the needs of different residents and creating a more comfortable living environment. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The following is further described in detail through specific implementation methods:

[0035] The reference numerals in the drawings of the specification include: core tube outer wall 1, partition wall 2.

[0036] Methods to reduce the common area of ​​super high-rise residential buildings, such as Figure 9 As shown, the following steps are included:

[0037] The first step is to obtain information about the super-high-rise building, including building layout, external dimensions, floor height, total height, and seismic fortification intensity. Subsequently, a structural finite element model is established based on the acquired super-high-rise building information. The structural finite element model is then input into structural calculation software, and the structural parameters of the main building structure are calculated through simulation to determine the core tube dimensions. Simultaneously, the locations and sizes of the holes that can be opened on each side of the core tube are determined based on the principles for opening holes in the core tube's exterior walls.

[0038] The principles for opening holes in the core tube exterior wall include:

[0039] 1. Measured from inside the core tube, the distance between the opening position of the core tube outer wall 1 and the corner is greater than or equal to 50 cm.

[0040] Explanation: This principle is to ensure that the integrity of the core tube structure is not affected by the openings. The openings are located at least 50 cm away from the corners to help prevent stress concentration caused by the openings, thereby reducing the risk of cracks.

[0041] 2. The number of openings in the exterior wall of the same core tube is less than or equal to two.

[0042] Explanation: Limiting the number of openings can reduce damage to the core's structural integrity. Each opening weakens the wall's continuity and stiffness, so limiting the number of openings helps maintain the overall stability and safety of the structure.

[0043] 3. When there are two holes, the distance between the two holes should not be less than 120cm:

[0044] Explanation: This principle ensures that even if there are two openings, there is sufficient wall support between them to maintain the stability of the wall. A distance of more than 120 cm between openings helps to distribute the load and reduce stress concentration, thereby reducing the risk of wall cracking.

[0045] The second step is to arrange the necessary horizontal and vertical transportation systems and duct shafts within the core tube. Elevators should be centrally located, and staircases should be used whenever possible to minimize common areas. The number of elevators should be determined based on capacity calculations and relevant regulations to avoid unnecessary installation to fill the core tube. The size and number of duct shafts should be calculated and determined according to regulations.

[0046] The third step is that after the second step is completed, there will be some remaining space in the core tube. This remaining space can be used to arrange secondary functions in the residential unit, such as bathrooms, kitchens, private elevators, entrances and other rooms with low lighting requirements for efficient use. In combination with the core tube exterior wall opening principle determined in the first step, door and window openings can be set, and the opening width can be set according to specific needs. At the same time, the opening height is less than or equal to the floor height.

[0047] The following will be through Case 1 to Case 3 and the attached Figure 1-6 The present invention is described in further detail.

[0048] Case 1 has a building height of 148.5m, a standard floor area of ​​1223.33㎡, a frame core tube (double tube) structure, an earthquake fortification intensity of 8 degrees, and a residential function.

[0049] Case 2 has a building height of 240.6m, a standard floor area of ​​1284.91㎡, a frame core tube structure, an earthquake fortification intensity of 6 degrees, and a residential function.

[0050] Case 3 has a building height of 182.6m, a standard floor area of ​​1264.94㎡, a frame core tube structure, an earthquake fortification intensity of 6 degrees, and a residential function.

[0051] The first step is to establish a structural finite element model based on the building information of Case 1, Case 2, and Case 3. Then, the structural finite element model is input into the structural calculation software, and the structural parameters of the main body of the building structure are calculated through simulation to determine the core tube size. Before the optimization according to this scheme, the architectural plan of the core tube is as follows: Figure 1 、 Figure 3 、 Figure 5 As shown, Figure 8 As shown, the core tube layer areas of Case 1, Case 2 and Case 3 are 233.23㎡, 313.74㎡ and 264.51㎡ respectively.

[0052] The second step is to arrange pipe shafts and traffic facilities in a centralized manner in the core tube. The size and number of pipe shafts are calculated and determined according to the specifications. Traffic facilities include vertical and horizontal traffic. Vertical traffic includes pedestrian stairs and public elevators. When arranging, public elevators and pedestrian stairs are arranged centrally. At the same time, scissor stairs are used as much as possible for pedestrian stairs to reduce the common area. The number of elevators is determined by calculating the elevator operating capacity and relevant specifications to avoid making redundant elevators in order to fill the core tube. Horizontal traffic includes walkways and vestibules. Walkways are arranged around vertical traffic as much as possible, and vertical traffic is connected to walkways through vestibules to facilitate entering and exiting elevator rooms and entering residential units.

[0053] The third step is to incorporate the remaining space in the core tube into the residential space for planning, and set up a partition wall 2 to isolate the remaining space from the common space. At the same time, according to the principle of opening holes, corresponding holes are opened in the outer wall 1 of the core tube to connect the remaining space with the residential space. Subsequently, the remaining part of the core tube is used to arrange the secondary functional rooms in the residential household. The secondary functional rooms include one or more rooms with lower lighting requirements such as bathrooms, kitchens, private elevators, and entrance halls. Residential bathrooms do not have mandatory lighting and natural ventilation requirements and can be set in the corner of the core tube. The entrance hall should consider the connection between the entrance and the living room in accordance with the principle of opening holes in the shear wall. The location of the kitchen should meet the lighting and natural ventilation requirements in accordance with the location of the opening holes in the shear wall. Then, consider setting up the entrance door, indoor corridors or door and window openings in accordance with the principle of opening holes in the shear wall. After optimization according to this plan, the architectural plan of the core tube is as follows Figure 2 、 Figure 4 、 Figure 6 shown.

[0054] According to the method described in the above patent, Figure 7 As shown, the core tubes of the super-high-rise residential projects in Cases 1 to 3 are optimized, and the proportion of indoor space arranged using the remaining space of the core tube is about 17%-40%, and the common area ratio of the standard floor is reduced by about 3%-9%.

[0055] The above is only an embodiment of the present invention, and common knowledge such as the specific technical solutions and / or characteristics in the solution are not described in detail here. It should be pointed out that the technical means for solving the problems in the above-mentioned embodiments of the present invention can be used in combination to solve multiple technical problems at the same time. For those skilled in the art, without departing from the technical solution of the present invention, several variations and improvements can be made, which should also be regarded as the scope of protection of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
