Abstract
Description
Technical Field
[0001] This utility model relates to the field of pressurized building technology, specifically to a pressurized building. Background Technology
[0002] High-altitude regions have low air pressure and thin air. To help people living or working in these areas adapt to the climate and reduce health risks caused by the climate, pressurized buildings have emerged.

[0040] See Figures 1-7 This embodiment provides a pressurized building, including an upper structure and a lower structure that are interconnected;
[0041] The superstructure includes prefabricated steel structure wall 1 and roof slab; see also Figure 1 and Figure 2In this embodiment, the prefabricated steel structure wall 1 includes multiple steel columns 1.1, steel beams 1.2, and bearing steel plates 1.3. The multiple steel columns 1.1 are vertically arranged on the concrete structure foundation 3; the steel beams 1.2 are connected between two adjacent steel columns 1.1; and the bearing steel plates 1.3 are arranged between two adjacent steel columns 1.1.
[0042] Preferably, in this embodiment, the pressure-bearing steel plate 1.3 is provided with an upper stiffening plate 1.4 along the vertical direction to enhance the structural strength of the pressure-bearing steel plate 1.3.

[0044] The lower structure includes a concrete foundation 3, which includes a reinforced concrete base 3.1 and embedded steel components. The embedded steel components are embedded in the reinforced concrete base 3.1 and are sealed to the prefabricated steel structure wall 1.
[0045] For details, see Figure 2 and Figure 3 The embedded steel components include multiple embedded steel columns 3.2, embedded steel beams 3.3, and embedded pressure-bearing steel plates 3.4.

[0046] Preferably, the embedded steel beam 3.3 is provided with a flange plate 3.5 along the horizontal direction to enhance the pull-out resistance of the reinforced concrete base plate 3.1 and the embedded steel component; the embedded pressure-bearing steel plate 3.4 is provided with a stiffening plate 3.6 along the vertical direction to enhance the structural strength.
[0047] In this embodiment, see Figure 1 The pre-embedded steel component protrudes from the upper surface of the reinforced concrete base plate 3.1 and is provided with ( Figure 1 The connection point 5 between the upper and lower structures is shown (the position of which can be adjusted according to actual construction needs). The connection between the embedded steel component and the upper surface of the reinforced concrete base plate 3.1 is coated with structural sealant to ensure sealing performance.
[0048] In this embodiment, the steel column 1.1 and the pre-embedded steel column 3.2 are connected in a one-to-one correspondence and sealed connection (welded connection is adopted in this embodiment), and the pressure-bearing steel plate 1.3 and the pre-embedded pressure-bearing steel plate 3.4 are connected in a one-to-one correspondence and sealed connection (welded connection is adopted in this embodiment).
[0049] In this embodiment, the pressurized building also includes a reinforced concrete floor slab 4, which is set on the frame formed by the steel beams 1.2. The floor slab adopts a reinforced concrete structure, which can further reduce the cost of the overall structure.
[0050] The pressurized building provided by this utility model adopts a prefabricated steel structure for the upper structure and a concrete structure for the lower structure. The combination of the prefabricated steel structure and the concrete structure reduces the amount of on-site wet work, shortens the construction period, and reduces the requirements for construction space. On the other hand, compared with the traditional pressurized building with an integral steel structure, the overall cost is lower.
[0051] See Figures 4-8 The upper structure also includes a sealing window 2, which is installed on the prefabricated steel structure wall 1;
[0052] The sealed window 2 includes an operable window sash 2.1, a fixed window sash 2.2, and a window frame 2.3. The window frame 2.3 is disposed between two adjacent steel columns 1.1. The fixed window sash 2.2 is fixedly disposed on the window frame 2.3 and / or the steel column 1.1. The operable window sash 2.1 is hinged to the steel column 1.1. The operable window sash 2.1 and the fixed window sash 2.2 are arranged side by side.
[0053] In this embodiment, the fixed window sash 2.2 includes a transparent panel 2.5 (preferably glass or PC endurance board, which needs to meet the pressure requirements), and a window baffle 2.4 is provided on the window frame 2.3 and / or steel column 1.1. The transparent panel 2.5 is fixedly installed on the window baffle 2.4 by fastening bolts 2.6, and a sealing strip is provided between the transparent panel 2.5 and the window baffle 2.4.
[0054] In this embodiment, the operable window sash 2.1 includes a transparent panel 2.5, and a window baffle 2.4 is provided on the window frame 2.3 and / or steel column 1.1. The transparent panel 2.5 is provided on the window baffle 2.4, and a sealing strip is provided between the transparent panel 2.5 and the window baffle 2.4.
[0055] In this embodiment, one side of the transparent panel 2.5 is hinged to the window baffle 2.4 set on the steel column 1.1 by a hinge 2.10, and the transparent panel 2.5 and the hinge 2.10 are connected by clamp bolts.
[0056] Preferably, in order to avoid interference and friction between the hinge and the steel column 1.1, which would affect the opening and closing of the transparent panel 2.5, a hinge pad 2.7 is also provided between the hinge 2.10 and the steel column 1.1.
[0057] A window lock 2.9 is provided on the side of the transparent panel 2.5 of the operable window sash 2.1 away from the hinge 2.10. The window lock 2.9 includes a handle and a handle retaining buckle. The handle is disposed on the transparent panel 2.5 of the operable window sash 2.1, and the handle retaining buckle is disposed on the window frame 2.3. The handle and the handle retaining buckle cooperate to lock the transparent panel 2.5. Preferably, the end of the handle is weighted so that the end of the handle hangs down naturally in the natural state.
[0058] In this embodiment, a gas spring 2.8 is provided between the transparent panel 2.5 and the window baffle 2.4 of the operable window sash 2.1. The opening direction of the operable window sash 2.1 faces inward, and the gas spring 2.8 is used to realize the automatic opening of the transparent panel 2.5. In this embodiment, the gas spring 2.8 adopts existing technology.
[0059] By incorporating a gas spring 2.8 and a window lock 2.9, the operable window sash 2.1 can be opened to meet the ventilation needs of the pressurized building. Specifically, in the non-pressurized state (normal state), the operable window sash 2.1 can be manually opened and closed via the window lock 2.9. In the pressurized state, the operable window sash 2.1 can be manually closed first. Then, upon entering the pressurized state, the increased internal pressure of the pressurized building causes the operable window sash 2.1 to be further pressed towards the sealing strip, thereby loosening the handle. The handle is designed with a heavy end, and gravity causes the handle to droop, disengaging it from the handle limit latch. The window lock 2.9 becomes ineffective, thus ensuring that the operable window sash 2.1 can be automatically opened by the gas spring 2.8 in the pressurized building under depressurization conditions, achieving automatic opening of the operable window sash 2.1 in emergency situations.
[0060] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
