Description

Technical Field

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

[0002] With the acceleration of urbanization and the continuous development of construction technology, super high-rise residential buildings have become an important part of modern cities due to their special role in saving urban land, improving the city's image, and promoting social investment. In these high-rise buildings, the design of the core tube is particularly critical. It not only carries the functions of transportation and evacuation, but also directly relates to the structural safety of the building. In the actual design process, factors such as earthquakes and wind loads need to be considered to determine the shape and size of the core tube. Due to the high height of super high-rise residential buildings, the earthquake and wind load forces are large, so a larger core tube is required to meet the lateral stiffness of the structure and ensure the stability of the building. However, in the architectural plane design, after the necessary vertical transportation facilities and pipe shafts are arranged inside the core tube, a large remaining space is often left. For the remaining space in the core tube, the current common treatment method is to increase the number of elevators or increase the size of the pipe shaft. Although this method can fill the remaining space, it will increase the public area of ​​the building and reduce the actual housing rate of the residents. Summary of the invention

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

[0004] To achieve the above object, the present invention adopts the following technical scheme: A method for reducing the common area of ​​super high-rise residential buildings, comprising the following steps: a first step, obtaining super high-rise building information, calculating the structural parameters of the main body of the building structure according to 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 the pipe shafts and traffic facilities in the core tube, and divide the core tube into the common space and the remaining space through the centralized arrangement of the 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 open corresponding holes on the outer wall of the core tube according to the opening principle to connect the remaining space with the residential space.

[0007] Generally speaking, in order to ensure the lateral rigidity of super high-rise buildings, except for necessary entrances and exits, the integrity of the outer wall of the core tube needs to be guaranteed to provide sufficient lateral rigidity. After 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 has 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 the remaining space is used as a common space. It seems that the space inside the core tube is fully utilized by filling the space. However, too many elevators will cause a series of problems such as excess capacity, increased energy consumption, and rising 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 of the remaining space after laying out the pipe shaft, 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 prevention. 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, the remaining space is connected with the residential space based on the principle of opening holes in the outer wall of the core tube, thereby 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 make use of the remaining space of the core tube, so 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 available 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 economic efficiency of the building, and realizes the efficient utilization of land resources.

[0011] Furthermore, the principle of opening holes is as follows: 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] The distance between the opening in the outer wall of the core tube and the corner is greater than or equal to 50cm, measured from the inside of the core tube; this principle is to ensure that the integrity of the core tube structure is not affected by the opening. A distance of at least 50cm from the corner helps prevent stress concentration caused by the opening, thereby reducing the risk of cracks.

[0013] The number of openings in the exterior wall of the same core tube is less than or equal to two; limiting the number of openings can reduce the damage to the structural integrity of the core tube. Each opening will weaken 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 distance between the two holes should not be less than 120cm: 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 120cm helps to disperse the load and reduce stress concentration, thereby reducing the risk of wall rupture.

[0015] Beneficial effect: By limiting the location and number of openings, the impact of the openings on the core tube exterior wall on the core tube 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, and 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, storey 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, and the core tube size is determined, 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 walking 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 centrally arranged.

[0020] Beneficial effect: The walking stairs are set as scissor stairs and arranged together with the public elevator, so as to reduce 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, when 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 of the core tube on the housing ratio of residents.

[0023] Furthermore, the remaining space in the core tube can be used to arrange secondary function 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 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, meet the needs of different residents, and create 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 Fig. 9 As shown, the following steps are included:

[0037] The first step is to obtain information about super high-rise buildings, such as building layout, external dimensions, floor height, total height, and seismic fortification intensity; then, a structural finite element model is established based on the obtained super high-rise building information; 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, so as to determine the size of the core tube, and at the same time, determine 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;

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

[0039] 1. Measured from the inside of 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 50cm.

[0040] Explanation: This principle is to ensure that the integrity of the core tube structure is not affected by the openings. The distance of the openings from the corners by at least 50 cm helps 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 structural integrity of the core. Each opening weakens the continuity and stiffness of the wall, 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. The distance between the holes above 120 cm helps to spread the load and reduce stress concentration, thereby reducing the risk of wall rupture.

[0045] The second step is to arrange the necessary horizontal traffic, vertical traffic and pipe shafts in the core tube. The elevators should be arranged as centralized as possible, and scissor stairs should be used as much as possible to reduce the common area. The number of elevators should be determined by calculating the elevator operation capacity and relevant specifications to avoid making redundant elevators to fill the core tube. The size and number of pipe shafts should be calculated and determined according to the specifications.

[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 house, 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 based on 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 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 m2, 313.74 m2 and 264.51 m2 respectively.

[0052] The second step is to arrange pipe shafts and traffic facilities in the core tube. The size and number of pipe shafts are calculated and determined according to 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 in a centralized manner. 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. The walkways are arranged around the vertical traffic as much as possible, and the vertical traffic is connected to the walkways through the vestibule to facilitate entering and exiting the elevator room and entering the residence.

[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 of the rooms with lower lighting requirements such as bathrooms, kitchens, private elevators, and entrance halls. The residential bathroom has no 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 by utilizing 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 known specific technical solutions and / or characteristics in the solution is 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, several modifications and improvements can be made without departing from the technical solution of the present invention, which should also be regarded as the scope of protection of the present invention, and 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.
