Description

TECHNICAL FIELD

[0001] The utility model relates to the field of resident building construction engineering design, especially suitable for total height 12-18 layers of resident building core tube structure. BACKGROUND

[0002] The resident building core tube is the core part of the building, mainly has the central core tube formed by the antechamber, elevator room, stairwell, pipe well, entrance door, evacuation door and the like enclosure, and forms an outer frame inner tube structure with the outer frame.

[0003] According to the national design specification and standard, the resident building core tube structure of different height or layer number is also required to be different, and the resident building is generally divided into the following ranges according to height: 1 layer-6 layers, 7 layers-11 layers, 12 layers-18 layers, 19 layers-33 layers (height 100 meters below), and building height 100 meters above. The core tube structure of each range is very different according to the requirements of the national design specification and standard, which also results in that the core tube structure of each range is also very different, and the core tube of each different height or floor range has its own obvious characteristics.

[0004] The resident building core tube of total height 12-18 layers has few use scenes, belongs to the "small" core tube, and the technical designers pay little attention to this kind of core tube, and the traditional design technical scheme has many defects, and needs to be improved and developed.

[0005] For the resident building, the area of the user after purchasing the housing includes the in-suit area and the public share area, and the range of the public share area includes the core tube, the equipment room, the outer wall insulation layer and the like. Among them, the core tube accounts for about 70% in the total public share area, and other public shares are almost "rigid" public shares, which are difficult to reduce, and how to reduce the area of the core tube is the key to reduce the public share area and improve the housing rate; in addition, whether the antechamber can be naturally lighted and ventilated is an important index for measuring the living quality.

[0006] For core tube structures in high-rise residential buildings with a total height of 12-18 stories, the traditional design schemes are as follows, along with the problems associated with each: 1. A core tube structure with one elevator serving two households per floor and a connecting corridor is used in 12-18 story residential buildings. To reduce the area of ​​the core tube, natural lighting and ventilation in the vestibule are often sacrificed. The consequence of this design is that the vestibule lacks natural lighting and ventilation, resulting in a poor user experience and reduced living quality. To meet design specifications and standards, mechanical pressurization and ventilation systems must be added to the vestibule and stairwell, increasing construction and operating costs. 2. Another type of core tube structure with one elevator serving two households per floor and a connecting corridor is used in 12-18 story residential buildings. The evacuation stairwell is oriented east-west. To allow for natural lighting in the vestibule, the east-west width of the vestibule is increased to create window space. This increases the shared area and reduces the width of the unit's interior space, which is detrimental to the interior space design. 3. A core-tube structure in a 12-18 story residential building with two elevators serving two households per floor results in a large shared area, high equipment investment, and poor natural lighting and ventilation in the anteroom. It also occupies a significant portion of the floor area, reducing the usable interior space. Designing a comfortable interior space with this type of core-tube structure is difficult. 4. While a core-tube structure in a 12-18 story residential building with two elevators serving multiple households per floor reduces the shared area per household, the middle units lack cross-ventilation, leading to a poor living experience. Natural lighting and ventilation in the anteroom of this type of core-tube structure are also limited.

[0007] With the development of the times and the improvement of living standards, people have higher and higher requirements for the quality of housing. How to ensure that public spaces such as the anteroom are transparent, bright, simple and square, with good natural lighting and ventilation, reasonable structural layout, low construction cost, and less land occupation under the premise of low common area ratio is a prominent problem and a difficult problem in the core tube structure design of 12-18 story residential buildings.

[0008] In response to the problems existing in the aforementioned traditional technical solutions, designers have been making unremitting efforts over the past decade to improve upon these shortcomings and perfect the 12-18 story core tube structure. The following design examples also illustrate the designers' continuous efforts to improve their solutions.

[0009] For example, 1, CN203008413U core tube arrangement and corridor design of unit type high-rise residential. The design needs to set up a contact corridor every floor, which is an open public space, about two meters away from the north side window of the middle house, and forms a view with the north room of the middle house, seriously affecting the privacy of the middle house; At the same time, the front room layout is irregular, and the whole core tube area is large, which is not conducive to reducing the public area; The core tube occupies more east-west direction surface width resources, and squeezes the surface width resources of the suite space, which is not conducive to the design layout of the suite space. 2, CN 105133861 A notch collection residential building in one elevator multi-family. It is a two elevator four family structure, and the front room of this scheme cannot be naturally ventilated, and the west side middle house cannot be north-south transparent, which greatly reduces the living quality. In order to make the east side middle house north-south transparent, an open corridor is set on the north side of each floor, which makes the privacy worse and reduces the safety of the whole unit. 3, CN 207063166 U is a kind of assembly type hybrid structure system suitable for high-rise residential building. It adopts the typical core tube structure of two elevators and multi-family. Although this kind of core tube can be naturally ventilated, the public area is large, the surface width resources are occupied, and the freedom of suite space design is limited. The middle house is not north-south transparent, and the living quality is very poor. 4, CN115075618 B one elevator two family high-rise residential traffic core. In order to meet the requirements of design specification, two elevators must be used, which increases the equipment investment and increases the public area. In order to make the pipe well area enough, the width of the evacuation staircase or the depth of the front room needs to be increased, which will increase the public area. The core tube occupies more surface width resources, which is not friendly to the design of the suite space.

[0010] From the above existing examples, it is not difficult to see that the design scheme of the core tube, to improve the living quality and reduce the public area of the core tube, is a difficult decision. It can be seen that:

[0011] (1) In order to reduce the public area of the core tube, the core tube with corridor of one elevator and two families is usually used. The front room is usually abandoned for natural lighting and ventilation, which not only reduces the living quality, but also increases the cost of mechanical pressurized air supply system and the daily operation and maintenance cost, which is not conducive to energy saving and environmental protection. Another kind of core tube with corridor of one elevator and two families is used. In order to natural lighting and ventilation, the front room usually adopts the way that the evacuation staircase is in the east-west direction, which occupies more surface width resources. In order to open the window surface width, the opening space is also needed, which greatly increases the public area and compresses the surface width of the suite space, which is not conducive to the design of the suite space.

[0012] (2) In order to reduce the public area of the core tube and improve the housing rate, the main direction is placed on the core tube of two elevators and multi-family, which adopts the way of two elevators and three families, four families centralized layout. Although the public area of each family is less, the middle house cannot be north-south transparent, which greatly affects the living quality.

[0013] (3) the core tube of two-stairs and two-houses type can ensure better space in the house, but the public area shared by each house is larger, if the front room of the core tube adopts natural lighting and ventilation, the public area will be larger, and the face width resource is occupied, which affects the freedom of the space design in the house.

[0014] Therefore, how to provide a core tube of a 12-18 story high-rise residential building with good ventilation and lighting effect, simple, clear, reasonable overall space layout, small public area, and less face width resource is a problem to be solved by those skilled in the art.

The core barrel structure of the resident building with a total height of 12-18 layers is truly realized, and it is more green and environmentally friendly. Example one:

[0066] When the total height of the floor is 12 layers, the contact corridor 1 can not be arranged, and the roof 19 connected with each unit is used as the contact corridor, and the roof 19 connected with each unit is used as the roof surface of each unit. Example two:

[0067] When the total height of the floor is 13 layers (including) -17 layers (including): at least one of the contact corridors 1 is arranged, and the roof 19 connected with each unit is used as the second contact corridor. Example three:

[0068] When the total height of the floors is 18 floors, the connecting corridor 1 is provided with two schemes:

[0069] Scheme one: the connecting corridor 1 is arranged at the 12th floor and the 17th floor.

[0070] Scheme two: the connecting corridor 1 is arranged only at the 14th floor, and the roof 19 of each unit is used as a second connecting corridor.

[0071] Through the arrangement of the connecting corridor 1 and the roof 19 of each unit, the east core tube A and the west core tube B are combined into an integrated two-lift four-house overall public transportation core tube structure. The one-lift two-house unit is realized, the area of the public transportation core tube is greatly compressed, the public proportion is reduced, and the housing rate is improved under the premise of ensuring the south-north permeability of the residents, good natural lighting and ventilation, high comfort, meeting the economic and practical requirements. And the core tube occupies less surface width resource, the edge of the outer side is regular, so that the internal layout of the space adjacent to the core tube is more reasonable.
