Description

Technical Field

[0001] The invention belongs to the technical field of building seismic isolation fire wall bodies, and in particular relates to a building suspended split seismic isolation fire wall body and a construction method thereof. Background Art

[0002] Seismic isolation buildings need to meet fire protection regulations when passing through the seismic isolation layer to form a closed fireproof space. Because the upper structure of the seismic isolation building is a translational structure, it is necessary that when the upper structure of the seismic isolation building moves parallely, the fireproof enclosed space still meets the requirements of the regulations and maintains the closedness of the fire partition.

[0003] At present, existing seismic isolation buildings mostly use masonry walls in the construction process of the seismic isolation layer to connect the upper and lower structures of the seismic isolation layer. When the seismic isolation building is subjected to a certain horizontal load, the masonry wall will break in the seismic isolation layer, affecting the fire resistance of the building; in addition, the masonry wall is a rigid structure, and the cost of repairing the seismic isolation layer after the wall is damaged is high, and it is difficult to construct in a limited space.

[0004] Therefore, there is a lack of a building suspended split-type seismic isolation fire wall body with a simple structure and a reasonable design and a construction method thereof. A suspended split-type seismic isolation fire wall body is used at the upper and lower structures where the horizontal seams of the seismic isolation layer of the building are disconnected, so as to solve the problem that the rigid connection between the upper and lower structures of the seismic isolation layer wall of the seismic isolation building cannot meet the decoupling problem between the displacement of the upper structure of the seismic isolation building and the lower fixed structure, and effectively solve the problem of damage to the seismic isolation layer wall and loss of fire protection function of the seismic isolation building wall.

[0071] The seismic isolation fire wall can slide along the top of the aerated concrete block wall 3 through the sliding mechanism;

[0072] Two groups of symmetrically arranged upper fireproof sealing layers are arranged between the upper hanging wall fixing plate 14 and the sealing plate member, two groups of symmetrically arranged lower fireproof sealing layers 4 are arranged between the bottom of the seismic isolation fire wall and the top of the aerated concrete block wall 3, and the sliding mechanism is located between the two groups of the lower fireproof sealing layers 4.

[0073] In this embodiment, the sealing plate member includes a lower connecting plate 11, a U-shaped member 10 connected to and fitted with the lower connecting plate 11, and a sealing plate 9 arranged between the bottom of the U-shaped member 10 and the top of the seismic isolation fire wall, and the wall hanging hook 12 is installed on the lower connecting plate 11;

[0074] The number of the hanging ears 13 and the number of the wall hanging hooks 12 are both multiple and one-to-one corresponding.

[0075] In this embodiment, the sliding mechanism includes two upper L-shaped parts 7 symmetrically arranged at the bottom of the seismic isolation fire wall and a bull's eye wheel 17 arranged at the bottom of the upper L-shaped part 7. Two symmetrically arranged lower L-shaped parts 5 are arranged on the top of the aerated concrete block wall 3. Leveling metal plates 6 are arranged on the top of the two L-shaped parts 5. The top of the bull's eye wheel 17 and the upper L-shaped part 7 are fixedly connected by bolts, and the bottom of the universal ball in the bull's eye wheel 17 fits into the top of the leveling metal plate 6.

[0076] In this embodiment, the two groups of upper fireproof sealing layers both include an upper silicon-titanium fireproof cloth 15 and a plurality of upper counterweight rods 16 arranged along the height direction of the upper silicon-titanium fireproof cloth 15. The top end of the upper silicon-titanium fireproof cloth 15 is sealed and fixedly connected to the upper suspended wall fixing plate 14, and the bottom end of the upper silicon-titanium fireproof cloth 15 is sealed and fixedly connected to the lower connecting plate 11.

[0077] like Figure 2 As shown, in this embodiment, the two groups of the lower fireproof sealing layer 4 include two layers of lower silicon-titanium fireproof cloth 4-1 and a plurality of lower counterweight rods 4-3 sandwiched between the two layers of lower silicon-titanium fireproof cloth 4-1 and arranged along the height direction of the lower silicon-titanium fireproof cloth 4-1, the bottoms of the two lower silicon-titanium fireproof cloths 4-1 are integrated, an intermediate pad 4-2 is arranged between the tops of the two lower silicon-titanium fireproof cloths 4-1, side pads 4-4 are arranged on the sides of the lower silicon-titanium fireproof cloth 4-1, and the bottom of the lower silicon-titanium fireproof cloth 4-1 extends to the side of the aerated concrete block wall 3.

[0079] In the present embodiment, the seismic isolation fire wall in the suspended split-type seismic isolation fire wall body adopts a light steel keel rectangular frame, a rock wool layer and a fireproof partition to form a lightweight fire wall. In this way, a split wall is formed by the lightweight fire wall and the aerated concrete block wall 3. When the seismic isolation building is subjected to a certain horizontal load, the lightweight fire wall can move horizontally along the vibration isolation gap at the top of the aerated concrete block wall 3, thereby avoiding the fracture of the masonry wall in the seismic isolation layer of the current seismic isolation building.

The upper fireproof sealing layer and the lower fireproof sealing layer 4 can solve the problem that the rigid connection of the seismic isolation building cannot meet the deformation and fracture when the upper structure is displaced, and on the other hand, it can meet the horizontal movement of the upper structure when the upper structure is deformed, thereby ensuring the closed fire protection function.
