Researching a prefabricated steel structure house that can withstand pressure and can be used in a transferable location is a new topic of plateau prefabricated buildings.

[0003] All existing prefabricated buildings are normal pressure structures, with no pressure difference inside and outside the house, and there is no need to design a sealed wall and transition cabin.

Therefore, the existing pressure rooms are all the size of containers, which brings great inconvenience to life and is not conducive to the residence of a large number of people. The existing reinforced concrete building structure can form a pressure-bearing space, which is a fixed building and cannot be transported and transferred according to work needs.

DETAILED DESCRIPTION

[0040] The embodiments of the present invention are described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways as defined and covered by the claims.

[0041] In plateaus and other environments with thin air and low air pressure, workers from plains often suffer from altitude sickness and have difficulty sleeping when living in ordinary closed houses. Therefore, it is necessary to change the indoor air pressure of houses in plateaus to create the same indoor environment as in plains. Researching a prefabricated steel structure house that can withstand pressure and can be used in a transferable location is a new topic of plateau prefabricated buildings.

[0042] In order to solve the above problems, this embodiment realizes a pressure-bearing building, such as Figure 1As shown, the pressure-bearing building includes a foundation 1 and a closed room 2 assembled on the foundation 1 and capable of bearing positive or negative pressure; the closed room 2 includes a beam-column assembly 2.1 and a pressure-bearing plate 2.2, the beam-column assembly 2.1 is a frame structure including columns and beams with load-bearing capacity and one or more installation areas, the number of the pressure-bearing plates 2.2 corresponds to the installation area, and the pressure-bearing plates 2.2 are detachably arranged on the installation area. The preferred installation area of ​​this embodiment is a square frame.

[0043] It should be noted that in this embodiment, the air pressure in the closed cavity is increased by an air compressor, and the air pressure in the closed cavity is greater than the external air pressure; since the pressure plate 2.2 is arranged inside the beam-column assembly 2.1, the pressure from the inside squeezes the pressure plate 2.2 so that the seal can fit the beam-column assembly 2.1 and the pressure plate 2.2 tightly, thereby enhancing the sealing effect. There is no load-bearing column inside the closed cavity, which is conducive to the allocation and use of the internal space of the closed cavity.

[0044] Specifically, Figure 2 As shown, the beam-column assembly 2.1 includes a top beam assembly 2.11 and a column assembly 2.12; the top beam assembly 2.11 includes one or more top beam pieces A1 located at the top of the pressure-bearing building and a connecting top beam A2 combined with the top beam piece A1 to form the top skeleton structure of the entire positive pressure building; the column assembly 2.12 includes a plurality of column pieces corresponding to the number of side wall surfaces of the pressure-bearing building and connecting columns B2 arranged on different wall surfaces and between adjacent column pieces, and the column pieces include one or at least two intermediate columns B1 arranged in parallel.

[0045] Furthermore, the top beam assembly 2.11 and the column assembly 2.12 are both self-sealing integral structures.

[0046] In this embodiment, the preferred top beam single piece A1 is an I-shaped structure, the connecting top beam A2 is a C-shaped beam structure, the two groups of connecting top beams A2 located at the ends and the top beam single piece A1 located in the middle form a ring-shaped top beam structure; the column single piece is a beam structure composed of a bottom beam B3 and an intermediate column B1 arranged perpendicular to the bottom beam.

[0047] like Figure 3 and Figure 4 As shown, the preferred connecting top beam A2 of this embodiment includes a beam body structure and a sealing plate A2-1 arranged at the end of the beam body structure. The beam body structure is a spliced ​​structure with a hollow portion formed by sequentially connecting three structural units with L-shaped cross-sections, and the beam body structure is provided with an installation portion for assembly with the top beam unit A1; the beam body structure and the sealing plate A2-1 are combined to form a self-sealing structure in which the hollow portion is completely isolated from the outside world.

[0048] like Figure 5 and Figure 6 As shown, the top beam single piece A1 of this embodiment is preferably a spliced ​​structure formed by two structural single pieces connected in parallel via a connecting plate, and the four free ends of the structural single pieces on the top beam single piece A1 are provided with docking portions that match the installation portions on the beam structure.

[0049] It should be noted that the structural unit in this embodiment is an integral structure with an L-shaped cross-section formed by two C-shaped plates with their opening directions stacked perpendicular to each other and the ends welded by the sealing plate A2-1, and a first reinforcing plate A2-2 is provided between the two stacked C-shaped plates to enhance its structural strength.

[0050] like Figure 7 and Figure 8 As shown, the connecting column B2 includes an L-shaped plate B2-1, a second reinforcing plate B2-2, an end flange plate B2-3 and a connecting flange plate B2-4; the second reinforcing plate B2-2 is arranged on the L-shaped plate B2-1 to enhance the structural strength of the connecting column B2; the two ends of the connecting column B2 are respectively provided with end flange plates B2-3 for connecting to the foundation 1 and the top beam A2, and the connecting flange plate B2-4 is arranged on the connecting column B2 to connect to the middle column B1.

[0051] like Fig. 9 As shown, the preferred intermediate column B1 of this embodiment includes a column body B1-1 and a column flange plate B1-2 arranged on the column body B1-1, and the intermediate column B1 is connected to the connecting flange plate B2-4 and / or to the top beam assembly 2.11 through the column flange plate B1-2.

[0052] like Fig.10 As shown, the pressure plate 2.2 includes a baffle 2.21, a mounting frame 2.22, a sealing ring 2.23 and a reinforcing structure 2.24; the pressure frame 2.22 is provided with a first mounting surface for mounting the baffle 2.21 and a second mounting surface for mounting the sealing ring 2.23; the pressure plate 2.2 is assembled and connected to the beam-column assembly 2.1 through the second mounting surface; the reinforcing structure 2.24 is arranged in the mounting frame 2.22 to enhance the pressure bearing capacity of the pressure plate 2.2. The preferred assembled connection in this embodiment is a threaded connection, and a threaded connection hole is provided on the second mounting surface of the pressure plate 2.2 to realize the threaded connection between the pressure plate 2.2 and the beam-column assembly.

[0053] It should be noted that, in this embodiment, the pressure plate 2.2 is laid inside the beam-column assembly 2.1, and the assembly error only exists in the installation area where the single pressure plate 2.2 is located, and will not cause cumulative errors, thereby effectively ensuring the accuracy of the pressure-bearing building installation process; the steps of the pressure-bearing building installation process are simplified, and the air tightness is checked after the overall installation of the pressure-bearing building is completed, and only the pressure plate 2.2 with poor sealing effect needs to be reworked.

[0054] Further, see Fig.11 , the enclosed room 2 is also provided with a partition 2.3, and the partition 2.3 is arranged in the enclosed cavity to divide the internal space of the enclosed cavity. It should be noted that in order to better install the partition 2.3, in this embodiment, a horizontal beam or a vertical beam for assembling the partition 2.3 can also be added in the enclosed cavity, and the horizontal beam or the vertical beam can choose a C-shaped plate as the main body; when it is necessary to divide the internal space of the enclosed room 2, the internal staggered C-shaped plates can make a preliminary division of the internal space of the enclosed cavity, and then the space division in the enclosed cavity is realized by laying the partition 2.3, and then a variety of functional areas can be arranged, such as conference rooms, rooms, etc.

[0055] The preferred sealing member in this embodiment is a sealing ring 2.23, which is made of elastic sealing material such as rubber, silicone and the like.

[0056] In order to better illustrate the advantages and purposes of this embodiment, the following will be explained based on the simulation calculation results: This embodiment considers the internal and external pressure difference of 0.05MPa, and establishes a structure size of 3×7.2×9m 3 The mechanical model of the pressure room is 3m×3m in size and made of Q345. The overall maximum deformation of the simulation result is 8mm. The maximum deformation of the mid-span area of ​​the double-layer lattice shell pressure structure specified in Appendix B Table B.2.4-2 of GB 50017-2017 "Steel Structure Design Standard" is L / 300, the maximum stress is 209mpa, and the safety factor reaches 1.65; the parameters in this embodiment are much smaller than the above standards, which shows that the structure has excellent pressure-bearing performance.

[0057] The present embodiment realizes a pressure-bearing building. In the present embodiment, the beam-column assembly 2.1 is a prefabricated structure. The beam-column assembly 2.1 is sealed by arranging a pressure-bearing plate 2.2 on the installation area. The prefabricated structure makes the volume of the beam-column assembly 2.1 ductile. Pressure-bearing buildings of different volumes can be assembled according to actual needs, which is conducive to life and work in a plateau environment and creates a good plateau working environment.
