Description

Technical Field

[0001] The utility model relates to a seismic isolation trench structure and belongs to the technical field of building seismic isolation. Background Art

[0002] The traditional seismic isolation trench structure adopts the method of setting a gap between the upper seismic isolation trench cover plate 1 and the lower vertical baffle plate 2 (or retaining wall), such as Figure 1 As shown, generally, the ends of the seismic isolation trench cover plate 1 and the vertical baffle plate 2 are flush, and a flexible material 3 (such as a polytetrafluoroethylene plate having the same width as the vertical baffle plate 2) is used to fill the gap.

[0003] Under the action of earthquake, the seismic isolation trench cover plate 1 moves horizontally relative to the vertical baffle plate 2; under the action of earthquake, it is difficult for the building to be completely restored, which may cause the following Figure 2 The situation shown in the figure where the seismic isolation trench cover plate 1 cannot cover the vertical baffle plate 2 will result in a gap between the seismic isolation trench cover plate 1 and the vertical baffle plate 2 (i.e. the seismic isolation trench cover plate 1 cannot completely cover the seismic isolation trench), which has a great impact on the waterproofing and thermal insulation of the building. Utility Model Content

[0004] In view of this, the utility model provides a seismic isolation trench structure, which can solve the problem of outdoor seismic isolation trench exposure caused by the inability to completely restore the building after an earthquake, and can improve the waterproof effect of the building.

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] This embodiment provides a seismic isolation trench structure, which can solve the problem of outdoor seismic isolation trenches being exposed due to the inability of the building to be completely restored after an earthquake, and can also improve the waterproof effect of the building.

[0026] like Figure 3 As shown, the seismic isolation trench structure includes: seismic isolation trench cover plate 1, vertical baffle plate 2 and seismic isolation cover plate extension 4; seismic isolation trench cover plate 1 is horizontally arranged, located above seismic isolation trench 8 and vertical baffle plate 2, and there is a gap between seismic isolation trench cover plate 1 and vertical baffle plate 2 as a seismic isolation gap, as an example, the seismic isolation gap width (referring to the distance between the lower end surface of seismic isolation trench cover plate 1 and the upper end surface of vertical baffle plate 2) is 20-30mm; in order to avoid the problem of outdoor seismic isolation trench being exposed due to failure to fully reset after an earthquake, seismic isolation trench cover plate 1 has a seismic isolation cover plate extension 4 extending outwardly on the outer side surface of vertical baffle plate 2, and seismic isolation cover plate extension 4 can be an integral structure with seismic isolation trench cover plate 1, or can be obtained by lengthening the end of seismic isolation trench cover plate 1, so that the cover plate formed by seismic isolation trench cover plate 1 and seismic isolation cover plate extension 4 is a cantilever structure as a whole. The seismic isolation cover plate extension can be equipped with reinforcing ribs.

[0027] The total length of the seismic isolation trench cover 1 and the seismic isolation cover extension 4 is not less than 2D, where D is the maximum displacement of the seismic isolation trench cover 1 (obtained after calculation based on the seismic isolation of the main structure of the building, which is the prior art). Figure 3 As shown, D is the width of the seismic isolation trench 8 obtained based on the seismic isolation calculation of the main building structure.

[0028] The upper end surface of the above-mentioned cover plate (seismic isolation trench cover plate 1 plus seismic isolation cover plate extension 4) is provided with a waterproof layer, which covers the upper end surface and the outer side surface of the cover plate as a whole ( Figure 3 and a sealing paste 6 is used to seal between the end of the waterproof layer (i.e., the dripping point 5) and the cover plate as a whole.

[0029] A polystyrene foam plastic plate 7 is arranged in the seismic isolation gap between the seismic isolation trench cover plate 1 and the vertical baffle plate 2 , and the inner and outer sides of the polystyrene foam plastic plate 7 are sealed with a sealing paste 6 .

[0030] When designing the seismic isolation trench structure of the above structure, first perform the seismic isolation calculation of the main structure to determine the maximum displacement D of the seismic isolation structure; then determine that the width of the seismic isolation trench is not less than D (in this example, the width of the seismic isolation trench is D). Then determine the overall length of the cover plate, which is not less than 2D (in this example, Figure 3 As shown in the figure, the overall length of the cover is 2D), and the thickness and reinforcement of the seismic isolation trench cover are determined according to the cantilever calculation. Next, the width of the seismic isolation joint is determined, and the width of the seismic isolation joint can be taken as 20 to 30 mm.

[0031] With the seismic isolation trench structure in the above-mentioned structural form, even if the building cannot be completely restored during an earthquake, the cover plate can still cover the entire seismic isolation trench 8 to avoid the situation of being exposed and affecting evacuation. At the same time, since the overall length of the cover plate exceeds the seismic isolation trench 8 and the vertical baffle 2, the protruding part forms a rain shield (similar to a canopy) and a drip point 5, which improves the waterproof effect.

[0032] like Figure 4 As shown, if there is an oblique member (such as a sloping top plate of a lane) at the isolation trench, the minimum vertical distance to avoid collision should be determined first, thereby determining the vertical size of the vertical baffle 2.

[0033] Although the utility model has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model. Therefore, these modifications or improvements made without departing from the spirit of the utility model are within the scope of protection claimed by the utility model.
