[0029] Figure 2 It is a schematic side view of the side structure of an underground entrance building according to a preferred embodiment of the present application.

[0030] Reference numerals in the drawings: 1 - arc-shaped roof; 2 - entrance isolation surface; 21 - aluminum decoration surface; 22 - stone decoration surface; 3 - arc-shaped support mechanism; 4 - glass filling surface; 5 - greening filling surface. Specific embodiments

[0031] The technical solutions of the present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0032] As Figure 1-2 shown, the present application provides an underground entrance building, including: an arc-shaped roof 1 and an entrance isolation surface 2.

[0033] Among them, the arc-shaped roof 1 is the main structure of the building of the present application. The arc-shaped roof 1 is in the shape of a single-layer reticulated shell and is arranged to climb from the ground to the open section of the entrance, that is, it is arranged to bulge upward in the center on the entrance side of the building, and its two sides and the rear side are connected to the ground at a preset slope, so that the arc-shaped roof and the ground form a shape similar to an "open shell" as a whole.

[0034] The arc-shaped roof 1 includes: an arc-shaped support mechanism 3 and a glass filling surface 4. The arc-shaped support mechanism 3 is arranged to bulge upward in the center, and its two sides are connected to the ground at a preset slope; the glass filling surface 4 starts from the top of the arc-shaped support mechanism 3 and fills in a preset area of the arc-shaped roof 1. The other areas of the arc-shaped roof 1 connected to the ground are non-preset areas.

[0035] That is to say, the arc-shaped support mechanism 3 plays an open support role on the front side of the building, that is, the open side, and the building structure from the arc-shaped support mechanism 3 to the ground around the building is a closed structure, and this closed structure includes a preset area filled with the glass filling surface 4. The "slope surface" at the top of the arc-shaped roof 1 is made for daylighting by setting the glass filling surface 4, and natural light is fully introduced into the entrance space, thereby improving the daylighting effect of the entrance.

[0036] The entrance isolation surface 2 is the open entrance end of the building of the present application. Its top is connected to the arc-shaped support mechanism 3, its bottom is connected to the ground, and it is vertically arranged on the entrance side of the building, so that the arc-shaped roof 1 and the entrance isolation surface 2 form a closed structure of the underground entrance building.

[0037] The connection structure between the arc-shaped roof 1 and the entrance isolation surface 2 can also be understood as that inside the structure of the entrance isolation surface 2 and the arc-shaped roof 1 is the indoor area for people to enter and exit the above-ground and underground areas, and outside the structure of the entrance isolation surface 2 and the arc-shaped roof 1 is the public open area.

[0038] Preferably, the area and position of the preset area can be set according to specific daylighting requirements, so as to achieve the best daylighting effect according to the specific geographical conditions of the building construction. The present application does not make specific limitations.

[0039] Preferably, to ensure the spatial comfort and structural stability of the building, the preset slope of the arc-shaped roof 1 is set to 20°, that is, the included angle between the arc-shaped roof 1 and the ground is 20°, and the height-span ratio of the arc-shaped roof is set to 1:3.

[0040] In a specific embodiment, the maximum opening span of the arc-shaped roof 1 is set within the range of 26 to 30 meters, and the maximum height from the ground at the highest point is within the range of 9 to 10 meters. The overall building achieves the best spatial comfort and structural stability in this design.

[0041] Preferably, specifically as Figure 2 shown, the center of the arc-shaped roof 1 is not only set to bulge upward but also set to bulge outward. Bulging upward means that the arc-shaped roof 1 has a height relative to the ground, and bulging outward means that the arc-shaped roof 1 bulges outward from the position of the entrance and exit, so that the arc-shaped roof 1 forms an eaves on the entrance and exit side.

[0042] Specifically, the arc-shaped support mechanism 3 is also set to bulge outward, so that the arc-shaped roof 1 forms an eaves on the entrance and exit side.

[0043] At the same time, the top of the entrance and exit isolation surface 2 is connected to the bottom of the arc-shaped support mechanism 3 at the preset indentation position, so that the entire arc-shaped roof 1 forms an eaves at the preset indentation position and on the entrance and exit side. The area within the preset indentation position can be understood as the central area of the building bounded by the preset indentation position, and the area outside the preset indentation position can be understood as the two-side areas of the building bounded by the preset indentation position.

[0044] Preferably, in the present application, the indoor net height of the underground entrance and exit building is greater than the first preset value, and the eaves height on the entrance and exit side is greater than the second preset value, and the preset indentation position is set according to the first preset value and the second preset value. That is to say, the length of the eaves of the arc-shaped roof 1 and the setting position of the entrance and exit isolation surface 2 are related to the indoor net height and eaves height of the building.

[0045] In a specific embodiment, the first preset value is set to 3 meters, and the second preset value is set to 8 meters. That is, the lowest point of the entrance and exit isolation surface 2 needs to be greater than 3 meters, so that the eaves height on the entrance and exit side is greater than 3 meters, and the highest point of the arc-shaped support mechanism 3 needs to be greater than 8 meters, so that the eaves width is controlled above 8 meters. The preset indentation position can be calculated according to these conditions.

[0046] Preferably, the entrance and exit isolation surface 2 includes: an aluminum decoration surface 21 and / or a stone decoration surface 22.

[0047] In a specific embodiment, the area where the top of the entrance and exit isolation surface 2 is connected to the bottom of the arc support mechanism 3 within the preset indentation position is the aluminum decoration surface 21, and the area where it is connected to the bottom of the arc support mechanism 3 outside the preset indentation position is the stone decoration surface 22. The exit and the entrance are respectively arranged at both ends of the aluminum decoration surface 21.

[0048] Preferably, the arc-shaped roof 1 further includes: a greening filling surface 5, which starts from the bottom of the arc support mechanism 3 connected to the ground and fills the non-preset area of the arc-shaped roof 1. That is to say, the greening filling surface 5 and the glass filling surface 4 jointly cover the entire arc-shaped roof 1, and the preset area corresponding to the lighting requirement is set as the glass filling surface 4, and the other areas are set as the greening filling surface 5. The greening filling surface 5 can be consistent with the scenery in the ground green belt, so that the building forms an upper roof lighting structure and a lower hidden landscape structure as a whole, making the building more beautiful.

[0049] Preferably, the underground entrance and exit building further includes: indoor facilities (not shown in the figure). The indoor facilities are arranged within the structures of the entrance and exit isolation surface 2 and the arc-shaped roof 1, including escalators and stairs.

[0050] The underground entrance and exit building provided by this application includes an arc support mechanism that is set to bulge upward on the entrance and exit side and is connected to the ground at both sides with a preset slope, and a glass filling surface filled in the preset area of the arc-shaped roof. This makes the building have a better lighting effect on the entrance and exit side due to the light transmission of the glass filling surface, and the structure of bulging upward on the entrance and exit side and being connected to the ground at both sides with a preset slope also makes the building have a certain width on the entrance and exit side, thus making the ventilation effect of the building better. Moreover, its arc-shaped roof structure also makes the landscape value of the building higher and can be more naturally integrated with the surrounding landscape environment.

[0051] The preferred embodiments of this application have been described in detail above. However, this application is not limited to the specific details in the above embodiments. Within the scope of the technical concept of this application, various simple modifications can be made to the technical solutions of this application, and these simple modifications all belong to the protection scope of this application.

[0052] In addition, it should be noted that, among the various specific technical features described in the above specific embodiments, they can be combined in any appropriate way without contradiction. To avoid unnecessary repetition, this application does not separately describe various possible combination methods.

[0053] In addition, any combination can be made between various different embodiments of this application as long as it does not violate the idea of this application, and it should also be regarded as the content disclosed by this utility model.
