Abstract
Description
Technical Field
[0001] The utility model relates to a civil air defense shaft structure, in particular to a civil air defense shaft structure connected with a seismic isolation ditch, and belongs to the technical field of building structures. Background Art
[0002] Seismic isolation buildings are buildings that have seismic isolation layers in their structures to achieve seismic isolation functions, including superstructures, seismic isolation layers, substructures, and foundations. The "Regulations on Seismic Management of Construction Projects" require that buildings such as schools, kindergartens, hospitals, nursing homes, child welfare institutions, emergency command centers, emergency shelters, and radio and television stations should adopt seismic isolation and shock reduction technologies. This project is a hospital, so seismic isolation design is adopted. At the same time, the basement part must be designed for civil defense. During the civil defense design, a civil defense shaft must be set up, adjacent to the outer wall of the basement, while the seismic isolation design requires a seismic isolation trench to be set up on the outer wall of the basement. Due to limited site space and the site roads surrounding the building, the outward movement of the civil defense shaft will occupy the road land, so it can only be set up adjacent to the outer wall of the basement. The civil defense shaft hinders the horizontal displacement of the seismic isolation building, and the setting of the civil defense shaft and the setting of the seismic isolation trench are in conflict. Utility Model Content
[0003] The purpose of the utility model is to solve the above-mentioned shortcomings and provide a civil air defense shaft structure connected to the seismic isolation ditch, which has a simple and reasonable structure, reduces the obstacles caused by the civil air defense shaft, gives full play to the role of the seismic isolation ditch, and improves the shock absorption capacity.
[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0005] A civil air defense shaft structure connected to a seismic isolation trench comprises a seismic isolation trench body arranged adjacent to a basement; the basement is connected to the shaft body, the shaft body is located between the seismic isolation trench body and the building; the shaft body comprises an upper shaft body and a lower shaft body which are relatively displaceable.
[0006] Furthermore, the building has a lower pier and an upper pier; the upper pier is connected to a cantilever beam; the lower pier is connected to a civil air defense roof plate; and the civil air defense roof plate is connected to a civil air defense beam.
[0007] Furthermore, the upper well body is composed of side beams; one side of the side beam is connected to the cantilever beam, and the other side is connected to the side wall of the seismic isolation trench body.
[0008] Furthermore, the lower well body is located between the civil defense beam and the side wall of the seismic isolation ditch body; the inner diameter of the upper well body is smaller than the inner diameter of the lower well body.
[0009] Furthermore, there is a movable gap between the bottom of the side beam and the lower shaft body; and a flexible filling layer is arranged in the movable gap.
[0010] Furthermore, a seismic isolation layer top plate is arranged in the upper pier; the seismic isolation layer top plate is connected to a layer of concrete piles; and a seismic isolation bearing is arranged between the upper pier and the lower pier.
[0011] The utility model has the following beneficial effects: by dividing the existing vertical shaft body into an upper shaft body and a lower shaft body that can be relatively displaced, the two are separated from each other and connected by a flexible filling layer; when the building encounters a natural disaster and vibrates, resulting in a deflection, the upper shaft body can be displaced relative to the lower shaft body and transmitted to the isolation ditch body, so that the setting of the civil defense shaft will not hinder the displacement of the building during the earthquake resistance process; at the same time, because the upper shaft body and the lower shaft body are interconnected and connected to the basement through the lower shaft body, the normal civil defense function of the civil defense shaft is not affected.

DETAILED DESCRIPTION
[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0016] The terms used herein, including technical and scientific terms, have the same meaning as those generally understood by those skilled in the art, unless the terms are defined differently. It should be understood that the terms defined in commonly used dictionaries have the same meaning as those in the prior art.
[0017] See also Figure 1-Figure 2
[0018] A civil air defense shaft structure connected to a seismic isolation trench comprises a seismic isolation trench body 2 arranged adjacent to a basement 1; the basement 1 is connected to the shaft body, the shaft body is located between the seismic isolation trench body 2 and a building 3; the shaft body comprises an upper shaft body 4 and a lower shaft body 5 which are relatively displaceable.
[0019] Furthermore, the building 3 has a lower pier 6 and an upper pier 7; the upper pier 7 is connected to a cantilever beam 8; the lower pier 6 is connected to a human defense roof plate 9; and the human defense roof plate 9 is connected to a human defense beam 10.
[0020] Furthermore, the upper well body 4 is composed of a side beam 11 ; one side of the side beam 11 is connected to the cantilever beam 8 , and the other side is connected to the side wall of the seismic isolation trench body 2 .
[0021] In this embodiment, since the upper well body 4 is surrounded by the side beams 11, it is an independent space relative to the lower well body 5, and is connected to the cantilever beam 8 of the building 3; therefore, when the building is in the process of earthquake resistance and deflection occurs, it can drive the entire upper well body 4 to move together and transfer it to the seismic isolation ditch body 2. The advantage of this design is that although the shaft body is between the building 3 and the seismic isolation ditch body 2, it will not hinder the displacement and energy absorption of the building 3 during earthquake resistance. It can solve the problem of the contradictory setting of the civil defense shaft and the seismic isolation ditch in the prior art, and can also solve the problem of the shaft body occupying excess space in order to avoid the basement.
[0022] Furthermore, the lower well body 5 is located between the civil defense beam 10 and the side wall of the seismic isolation ditch body 2 ; the inner diameter of the upper well body 4 is smaller than the inner diameter of the lower well body 5 .
[0023] Since the upper well body 4 is independent of the lower well body 5, it should be able to move as a whole relative to the lower well body 5, so the inner space is formed by the side beams 11 and can move as a whole. Under normal conditions, the lower well body and the basement can be connected.
[0024] Furthermore, there is a movable gap between the bottom of the side beam and the lower shaft body; a flexible filling layer 12 is arranged in the movable gap.
[0025] Furthermore, a seismic isolation layer top plate 13 is arranged in the upper pier 7; the seismic isolation layer top plate 13 is connected to a layer of concrete piles 14; and a seismic isolation bearing 15 is arranged between the upper pier and the lower pier.
[0026] Finally, it should be noted that the above embodiments are only for illustrating the technical solution of the utility model rather than limiting it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
