The utility model has the advantages that: the natural lighting, ventilation and evacuation of the basement are solved, the energy and the land are saved, and the environmental quality of the space of the basement is improved.
Description
Technical Field
The utility model belongs to the technical field of constructional engineering, and particularly relates to a sunk courtyard for fire-proof partition sharing natural lighting, ventilation and evacuation of a basement.
Background
The development of the underground space is beneficial to improving the utilization value of the land, but the confined space of the basement gives people the sense of depression, and the artificial lighting and the mechanical ventilation consume a large amount of energy, so that the basement ventilation shaft rising out of the ground brings adverse effects to the landscape. In engineering, under the condition that the range of the basement roof is allowed, the lighting well is arranged by a common design method, but the lighting well is usually designed in a fireproof partition and has a single function. How to integrate nature in basement design, improve space environment quality, save energy and land, and be easy for engineering coordination implementation is an engineering problem worthy of research.
Disclosure of Invention
The utility model provides a sinking yard structure for lighting, ventilation and evacuation shared by fireproof subareas of a basement on the premise of the existing standard, and can solve the problems of natural lighting, ventilation and evacuation for adjacent fireproof subareas of the basement.
The utility model adopts the following technical scheme: the basement fireproof partition is provided with a sinking yard structure at the adjacent part of the basement fireproof partition, the sinking yard structure comprises a sinking yard arranged at the adjacent part of the basement fireproof partition, the sinking yard is provided with an outdoor stair which is directly communicated with the ground, and the basement is provided with a fireproof solid wall and an opening wall hole for lighting, ventilation and evacuation of the fireproof partition towards the outer wall of the sinking yard.
The basement fireproof subareas are two to four, and the two to four basement fireproof subareas are distributed around the sinking courtyard.
The application range of the utility model is as follows: the method is suitable for summer heat, winter cold, summer heat, winter warm and mild areas in climate zones; each sinking yard is applicable to sharing between two and four fireproof partitions; the method is suitable for basements with burial depths of less than 10 meters; not applicable to all kinds of situations where specifications are well defined.
The utility model has the advantages that: the natural lighting, ventilation and evacuation of the basement are solved, the energy and the land are saved, and the environmental quality of the space of the basement is improved.
Drawings
Fig. 1 is a schematic plan view of the present utility model for two adjacent fire zones.
Fig. 2 is a schematic plan view of the present utility model for three adjacent fire zones.
Fig. 3 is a schematic plan view of the present utility model for four adjacent fire zones.
Description of the embodiments
The utility model is further described below with reference to the accompanying drawings.
As shown in fig. 1: two adjacent fireproof partitions A, B of the basement share a sinking yard 1; the basement is faced to the submerged yard outer wall, fireproof solid walls 21 and 22 are arranged at the fire wall, the rest is open wall openings 31 and 32, and the length of the fireproof solid walls 21 and 22 is not less than 2 meters; the fireproof subareas A, B are respectively naturally lighted, ventilated and evacuated to the sinking courtyard 1 through the open wall openings 31 and 32, and the sinking courtyard is designed to be evacuated to the ground by the outdoor stairs 4; the outdoor stairs 4 are arranged adjacent to the fireproof solid wall 21, and the distance between the outdoor stairs 4 and the edges of the open wall openings 31 and 32 is not less than 2 meters; the face-to-face distance of the open wall openings 31, 32 is not less than 6 m.
As shown in fig. 2, three adjacent fire-resistant partitions A, B, C of the basement share a sinking yard 1; the basement is provided with fireproof solid walls 21, 22 and 23 only at the fire wall, and the rest are open wall openings 31, 32 and 33, wherein the length of the fireproof solid walls 21 is not less than 2 meters, and the length of the fireproof solid walls 22 and 23 is not less than 4 meters; the fireproof subareas A, B, C are respectively naturally lighted, ventilated and evacuated to the sinking courtyard 1 through the open wall openings 31, 32 and 33, and the sinking courtyard is designed to be evacuated to the ground by the outdoor stairs 4; the outdoor stairs 4 are arranged adjacent to the fireproof solid wall 21, and the distance between the outdoor stairs 4 and the edges of the open wall openings 31, 32 and 33 is not less than 2 meters; the face-to-face distance of the open wall openings 31 and 32, 31 and 33, 32 and 33 is not less than 6 m.
As shown in fig. 3, four adjacent fire-resistant partitions A, B, C, D of the basement share a sinking yard 1; the basement is provided with fireproof solid walls 21, 22, 23 and 24 only at the fire wall, and the rest are open wall openings 31, 32, 33 and 34, the lengths of the fireproof solid walls 21 and 23 are not less than 2 meters, and the lengths of the fireproof solid walls 22 and 24 are not less than 4 meters; the fireproof subareas A, B, C, D are respectively naturally lighted, ventilated and evacuated to the sinking courtyard 1 through the open wall openings 31, 32, 33 and 34, and the sinking courtyard is designed to be evacuated to the ground by the outdoor stairs 4; the outdoor stairs 4 are arranged adjacent to the fireproof solid wall 21, and the distance between the outdoor stairs 4 and the edges of the open wall openings 31, 32, 33 and 34 is not less than 2 meters; the face-to-face distance of the open wall openings 31 and 32, 31 and 33, 32 and 33, 33 and 34 is not less than 6 m.
The drainage design of the sinking courtyard, the form and the position and the width of the outdoor stairs, the positions of the fire wall and the fireproof solid wall are determined by engineering design according to reality, the arrangement balance of the opening wall openings is realized as much as possible so as to be beneficial to the uniform lighting of the basement, the width and the area of the opening wall openings are determined according to the evacuation width and the natural ventilation area requirement of the fireproof partition passing through the sinking courtyard, and the actual size of the sinking courtyard is determined by comprehensive relevant factors.
