However, the description of these examples is not intended to limit the scope of the utility model in any way. According to specific application scenarios and needs, these numerical values or numerical ranges can be set otherwise.

[0026] As described above, the sealing between the corrugated plates of the top frame, between the ceiling edge boards, and between the circumferential beams of the edge area of the corrugated plates and the top frame in the prior art is insufficient, and a solution that can both ensure sealing and save manufacturing cost has not been found. The assembled ceiling proposed in the embodiments of the utility model at least partially solves the above problems. The structure and working principle of the assembled ceiling according to the example embodiments of the utility model will be described below with reference to Figs. 1-3 The assembled ceiling of the utility model embodiments mainly includes a frame beam, an edge sealing connecting plate 6, a ceiling edge board 5, a reinforcing plate 3, a main corrugated plate 1 and an edge corrugated plate 2, wherein the frame beam is hoisted at the bottom of the base top frame by a hoisting rod, and a plurality of frame beams are connected to each other to form a top frame; the ceiling edge board 5 is used to provide edge sealing for the ceiling and the storage tank; the main corrugated plate 1 and the edge corrugated plate 2 are both covered on the top frame; the edge sealing connecting plate 6 is used to be fixedly connected between adjacent ceiling edge boards 5; the reinforcing plate 3 is used to be fixedly connected with the frame beam, the edge sealing connecting plate 6 and the clamping plate, etc. Those skilled in the art can understand that the assembled ceiling of the utility model embodiments can be used for any scenario-built storage tank engineering structure, and for the convenience of description, the assembled ceiling for large LNG storage tanks is described below as an example.

[0027] In order to make conveniently, a plurality of corrugated plates are spliced to cover the top frame, and the embodiment of the utility model solves the problem of splicing and sealing between adjacent corrugated plates. In an embodiment, the corrugated part of each corrugated plate is manufactured to be the same shape, that is, the shape and size of the peak part 11, the valley part 12 and the transition part 13 are the same, so that the profiles of the corrugated parts of adjacent corrugated plates can be matched and lapped, in this case, a labyrinth sealing surface is formed between the matched and lapped profile parts, the sealing performance between adjacent corrugated plates is greatly improved, and the matched and lapped profiles can also provide horizontal positioning, avoiding horizontal movement of the corrugated plate during use, thereby affecting the sealing performance. At the same time, no additional parts are needed to seal between adjacent corrugated plates, greatly reducing the manufacturing cost.

[0028] In an embodiment, the corrugated part profile of the adjacent corrugated plates matched and lapped can only contain one valley part 12 and one transition part 13, or can contain one valley part 12, transition part 13 and peak part 11 at the same time, or can contain multiple valley parts 12, transition parts 13 and peak parts 11 at the same time. In fact, lapping too many profiles can further improve the sealing performance, but at the same time, it causes waste of corrugated plate materials.

[0029] In an embodiment, the profile of the corrugated part can be trapezoidal, semicircular, semi-elliptical, triangular, square or rectangular. However, the structure strength, sealing performance and manufacturing difficulty of the trapezoidal corrugated part profile are the best.

[0030] In an embodiment, the corrugated plate can be divided into a main corrugated plate 1 and an edge corrugated plate 2. The main corrugated plate 1 can be an integral corrugated plate or can be composed of a plurality of corrugated plates spliced and sealed with each other. The main corrugated plate 1 covers most of the area of the top frame, so the size of the main corrugated plate 1 is not strictly required, and the length and width of the plate can be set at will. The edge corrugated plate 2 near the edge area needs to ensure that there is no gap between the edge corrugated plate 2 and the ring beam 7 near the edge of the top frame. Especially for a special-shaped top frame, the size of each edge corrugated plate 2 can be different, so the manufacturing difficulty of the edge corrugated plate 2 is higher.

[0031] In an embodiment, the edge corrugated plate 2 is provided with a corrugated part and a straight plate part 21, the straight plate part 21 extends in the horizontal direction towards the ceiling edge plate 5, and the straight plate part 21 is lapped and sealed with the top surface of the ring beam 7 near the edge of the top frame. On the one hand, the edge of the straight plate part 21 is shaped according to the direction of the ring beam 7, which is much simpler than shaping the corrugated part. On the other hand, such a setting will not affect the profile of the corrugated part of the edge corrugated plate 2, and at the same time, the edge corrugated plate 2 can be set to a smaller size, and it is also easier to shape a smaller size workpiece.

[0032] In one embodiment, the mounting vertical plate 33 of the reinforcing plate 3 is arranged on the outer periphery of the upper edge of the top frame, and adjacent mounting vertical plates 33 are fixedly connected and sealed by the edge sealing connecting plate 6.

[0033] By setting the reinforcing plate 3, the ceiling panel on the outer periphery of the upper edge is fixedly connected to the top frame. In one embodiment, the reinforcing plate 3 is formed into a "Z" shaped structure. Specifically, it is provided with a horizontally extending base plate 32, which is used to fix with the frame beam. The two ends of the base plate 32 respectively form a vertically extending mounting plate 33 and a reinforcing plate 31. The mounting plate 33 extends upward to be fixedly connected with the edge sealing connecting plate 6, the clamping plate and the glass cloth on the outer periphery of the upper edge. The reinforcing plate 31 extends downward to clamp the frame beam, thereby providing structural reinforcement to the reinforcing plate 3, preventing the reinforcing plate 3 from deforming under stress, thus ensuring the glass cloth is clamped and installed firmly, and at the same time ensuring the sealing of the ceiling edge sealing plate 5.

[0034] In one embodiment, the mounting vertical plate 33 of the reinforcing plate 3 is fixedly connected to one or both sides of a clamping plate, which works together with the mounting vertical plate 33 to clamp the glass cloth.

[0035] A circumferential beam 7 is provided at the edge of the top frame, and the ceiling sealing plate 5 on the lower outer perimeter is fixedly connected to the circumferential beam 7. In one embodiment, the circumferential beam 7 can be an "I"-shaped beam, and the ceiling sealing plate 5 is directly fixed to the flange of the "I"-shaped beam, or fixed to the web of the "I"-shaped beam through an adapter. In another embodiment, the circumferential beam 7 can be a "T"-shaped beam, and the ceiling sealing plate 5 is directly fixed to the web of the "T"-shaped beam. Fixing the ceiling sealing plate 5 on the lower outer perimeter to the circumferential beam 7 stabilizes the position of the ceiling sealing plates 5 on the upper outer perimeter, ensuring the sealing performance of the ceiling sealing plates 5. The circumferential beam 7 and the ceiling sealing plate 5 on the lower outer perimeter are fixedly connected by a fixing connector 4. For example, the fixing connector 4 can be a bolt and nut connection, riveting, or welding.

[0036] In one embodiment, to ensure good sealing between the circumferentially arranged ceiling edge sealing panels 5, an edge sealing connecting plate 6 is provided between circumferentially adjacent ceiling edge sealing panels 5. This provides load-bearing capacity to the ceiling edge sealing panels 5 and also covers and seals any gaps that may exist between adjacent ceiling edge sealing panels 5.

The description of preferred embodiments involves combinations of features, which may exist independently or in combination; this utility model is not particularly limited to the preferred embodiments.
