The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0040] Example 1:

[0041] See Figures 1-9 A pressure-bearing room can have its interior installed floor, the floor comprising multiple intermediate templates 1, which are arranged in an array along the horizontal and vertical directions; each intermediate template 1 includes a sealing edge beam 3 and a first panel 4;

[0042] The sealing edge beam 3 comprises a square beam body composed of a cover plate 3.1, a sealing plate 3.2, an inner side partition plate 3.3 and an outer side frame 3.4, wherein the inner side partition plate 3.3 and the outer side frame 3.4 are oppositely arranged, the cover plate 3.1 and the sealing plate 3.2 are oppositely arranged, the sealing plate 3.2 is located at the bottom and is sealingly connected between the inner side partition plate 3.3 and the outer side frame 3.4, and the cover plate 3.1 is located at the top and is detachably connected (preferably bolted) with the outer side frame 3.4.

[0043] The plurality of sealing edge beams 3 in the intermediate formwork are sequentially connected to form a first frame assembly, and the first panel 4 is arranged on the first frame assembly and sealingly connected between the first panel 4 and the inner side partition plate 3.3.

[0044] As shown in Figure 2 , Figure 3 , Figure 5 , the intermediate formwork forms a sealed formwork structure through the sealing edge beam 3 and the first panel 4, and the detachable connection of the cover plate 3.1 facilitates the installation of the intermediate formwork; before the cover plate is installed, the bolt assembly 9 can be placed in the middle of the square beam body to achieve the bolted connection of the outer side frames between adjacent formworks, thereby achieving the assembly of adjacent formworks, so that the installation of the floor from the inside of the pressure-bearing room is realized.

[0045] Preferably, the floor further comprises a plurality of outer side formworks 2 arranged along the outer side of the array group, as shown in Figure 1 , that is, the intermediate position of the floor is arranged with a plurality of intermediate formworks, and the edge position of the floor is arranged with outer side formworks, and the outer side formwork mainly serves to connect the floor with the side formwork (not shown) of the pressure-bearing room.

[0046] The outer side formwork 2 comprises a second panel 10 and a second frame assembly, the second frame assembly comprises a plurality of sealing edge beams 3 and at least one connecting beam 8, and in the embodiment, the plurality of sealing edge beams 3 are sequentially connected to form a beam group, and the at least one connecting beam is sequentially connected to form a connecting beam group (when there is only one connecting beam, the single connecting beam is the connecting beam group), and the beam group and the connecting beam group are connected to form the second frame assembly; the second panel 10 is arranged on the second frame assembly, and the second panel 10 is sealingly connected with the connecting beam 8 and the inner side partition plate 3.3 in the second frame assembly.

[0047] In the embodiment, the first frame assembly and the second frame assembly are both annular planar frame structures with the first end connected to the second end. Similarly, the outer side formwork forms a sealed formwork structure through the second panel, the sealing edge beam and the connecting beam, and the connecting beam serves to connect the floor with the side formwork of the pressure-bearing room, and the connecting beam can serve as a connecting structure and a bearing structure around the floor, effectively reducing the deformation of the formwork at the intermediate position and increasing the air tightness of the entire floor.

[0048] The sealing connection in the embodiment is preferably welding, and other connection forms capable of achieving sealing can also achieve the same effect, for example, sealing glue is applied after bolt connection.

[0049] Referring to Figure 8 , the sealing strips 6 are arranged between the sealing edge beams 3 of the two adjacent middle formworks 1, between the sealing edge beams 3 of the two adjacent outer formworks 2, and between the sealing edge beams 3 of the middle formwork 1 and the sealing edge beams 3 of the outer formwork 2 to achieve sealing, and the limiting strips 7 are arranged between the two sealing edge beams 3 to achieve spacing of the gaps for accommodating the sealing strips 6 between the two sealing edge beams 3.

The arrangement of the sealing strips 6 can solve the air tightness problem between the adjacent formworks, and the arrangement of the limiting strips 7 can prevent the relative rotation between the adjacent formworks under the action of the air pressure in the pressure bearing room, so that the sealing strips 6 are not extruded and deformed, and the air pressure is not released, thereby ensuring the normal sealing effect of the sealing strips. Meanwhile, the mounting holes on the limiting strips serve as the connecting structure, which increases the friction between the formworks and effectively avoids the shearing fracture of the connecting bolts.

In this embodiment, the distance between the sealing strip and the nearest limiting strip is 5-7 mm. The sealing strip can be welded on the outer side frame or clamped in the groove of the outer side frame. The limiting strip can be welded on the outer side frame or integrally formed with the outer side frame.

[0054] Referring to Figure 7 , the connecting beam in this embodiment is a box beam, which includes a top plate 8.2, a web plate 8.3, a rib plate 8.4, and a bottom plate 8.5.
