Description

Technical Field

[0001] The invention belongs to the technical field of prefabricated buildings and relates to a sliding seismic isolation modular building. Background Art

[0002] Modular construction refers to a building form that uses a room unit as a prefabricated component unit, which is prefabricated in the factory and then transported to the construction site for installation. The prefabricated module can be a room unit with complete pipe network decoration such as heating, sewerage and lighting. It is the highest integrated form of industrialized prefabricated buildings. Modular construction has the advantages of short construction period, labor saving, construction safety, and quality assurance, which is in line with the concepts of building industrialization and low-carbon construction.

[0003] The seismic performance of modular building structures depends on the mechanical properties of the modules themselves and the deformation coordination between modules. Considering the transportation, hoisting and building use requirements, the cross-section of the module unit components is relatively thin, and because it has non-structural components such as lightweight partitions, doors, and windows, the deformation limit requirements of the structure are relatively high. Taking sufficient seismic measures at the module joints will make the node area connection structure very complicated, which is not conducive to on-site assembly and is not economical.

[0004] The use of seismic isolation settings can reduce a large amount of seismic effects transmitted to the upper structure, and reduce the force requirements of the upper module units and the connections between module units. CN111827762A, CN206521843U, etc. have similar designs. However, there is currently no modular building structure seismic isolation system that can be widely promoted. For example, the use of spring isolators or dampers at the foundation is relatively complex; the use of sand cushion layers for vibration reduction has the risk of liquefaction; the cost of rubber seismic isolation bearings is relatively high; for sliding seismic isolation, the setting of limiters may cause the upper structure to be suddenly stressed and increase the risk of overturning.

[0005] It can be seen that appropriate seismic isolation measures should be effective in any horizontal direction and should not have adverse effects in other degrees of freedom. In addition, the seismic isolation structure should meet the deviation requirements caused by construction and maintain effectiveness within the allowable range. For modular buildings, which are a fast construction method, the seismic isolation measures should be simple in structure, low in cost, insensitive to construction errors, and can achieve the design goals of sliding seismic isolation under different fortification intensities. However, there are currently no reports on seismic isolation devices that meet the above requirements, and the present invention is proposed based on this. Summary of the invention

[0006] The purpose of the present invention is to provide a sliding isolation modular building. By arranging a sliding layer and a sliding control component between the module group and the foundation, the seismic response of the superstructure is reduced and the sliding isolation design goals under different fortification intensities are met, the lightweight design of the module unit is promoted, the connection between modules is simple and fast, the non-structural components inside the integrated module are effectively protected, and the problems of module structure design, construction and use caused by the current reliance on earthquake-resistant measures are improved.

[0007] The purpose of the present invention can be achieved by the following technical solutions:

[0008] A sliding isolation modular building, comprising:

[0009] The group of modules that make up the bulk of the building;

[0010] A building foundation that supports the module group;

[0011] A sliding layer between the module group and the building foundation, comprising an upper sliding interface and a lower sliding interface respectively fixedly connected to the bottom of the module group and the top of the building foundation, and a sliding medium disposed between the upper sliding interface and the lower sliding interface;

[0012] And a sliding control component which connects the module group and the building foundation and is used to control the sliding state.

[0013] Furthermore, the module group is an upper integral structure formed by reliable connection of a plurality of module units and a top roof panel. The reliable connection method is selected according to the appropriate connection of different components, such as prestressed connection, lock connection, etc., to ensure the connection stability between the components.

[0014] Furthermore, the module unit is a 3D solid component, a 2D panel component or a 1D beam-column component. More preferably, the structural components in the module unit can be welded by steel components or cast as a whole by concrete in the factory according to actual needs; the non-structural components can be completed by using different materials, door and window positions and sizes, and water and electricity network layout designs according to the needs of building use. The specific structure of the module unit in this part is conventional technology in the field and will not be repeated here.

[0015] Furthermore, the top roof panel is a cast-in-place concrete slab or a composite floor slab;

[0016] Different module units are connected by bolt connection or prestressed connection.

[0017] Furthermore, the building foundation is a strip foundation or a raft foundation, etc.

[0018] Furthermore, the upper sliding interface and the lower sliding interface are both made of rigid plates. Specifically, the rigid plates can be made of steel plates, stainless steel plates, aluminum alloy plates, etc. according to requirements such as rigidity and cost.

[0019] Furthermore, the upper sliding interface and the module group are connected by anchoring, and specifically, the anchoring connection method can be anchoring measures such as steel bar anchoring and shear nails;

[0020] The downward sliding interface is bonded to the building foundation, and specifically, the bonding material may be steel structure adhesive or the like.

[0021] Furthermore, the material of the sliding medium is molybdenum disulfide, polytetrafluoroethylene, polyethylene, nylon or graphite, which is combined with the upper sliding interface or the lower sliding interface in the form of uniform coating or embedding.

[0022] Furthermore, the slip control component is a brittle connection material that fixes the module group and the building foundation, and the stress fracture threshold of the brittle connection material is adjusted according to the slip requirements between the module group and the foundation. Exemplarily, the brittle connection material can be ceramic or glass, or other materials that will break when subjected to a certain force can be selected as needed.

[0023] Furthermore, a sliding space is reserved between the module group and the building foundation. Specifically, the sliding space is formed by widening the foundation according to the designed sliding amount, that is, under the action of an earthquake, the sliding displacement of the module group relative to the foundation does not exceed the size of the widened foundation.

[0024] Compared with the prior art, the present invention has the following advantages:

[0025] (1) Since the module unit itself contains a floor, a sliding layer can be conveniently set directly between the bottom of the module and the foundation;

[0026] (2) Compared with the seismic strengthening measures for modular buildings, the setting of sliding layers can reduce the amount of earthquake action on the upper structure, making the module unit lighter, reducing the bearing capacity and stiffness requirements of the connection between adjacent modules, reducing the deformation of the upper module structure, and protecting the non-structural components in the module unit;

[0027] (3) The modular structure has a relatively rigid module unit, and the interlayer deformation is more significant. Setting a sliding layer can make the deformation of the seismic isolation performance more fully exerted;

[0028] (4) By adjusting the sliding control components, the sliding isolation design goals of modular buildings under different fortification intensities can be achieved;

[0029] (5) By adjusting the slip medium in the slip layer, the seismic response of the structure can be significantly reduced, ensuring the integrity of the structure during slip, and adapting to the stress requirements of different plane layouts and structural forms, thereby reducing the requirements for lifting and transportation, and making module splicing more efficient and safe;

[0030] (6) The setting of roof panels increases the mechanical integrity of the modular building structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and specific operation process, but the protection scope of the present invention is not limited to the following embodiments.

[0042] In the following implementation manners or examples, unless otherwise specified, functional components or structures are conventional components or conventional structures used in the art to achieve corresponding functions.

[0050] In a more specific embodiment, the top roof panel 102 is a cast-in-place concrete panel or a composite floor panel;

[0051] Different module units 101 are connected by bolt connection or prestressed connection.

By adopting the anchoring method to form the upper sliding interface 201 and the module group 1 into a whole, in this way, in the production process of the bottom module unit 101, the entire upper sliding interface can be made without demoulding, which is convenient for production. The sliding interface 203 is connected to the building foundation 3 by bonding, which can better take into account the leveling function of the bottom and avoid the module group from tilting after the overall structure is installed.

It should be noted that, in the area between the building foundation and the module group, except for the area where the slip layer is not provided, the building foundation and the module group are basically out of contact with each other in the remaining area where the slip layer is not provided. In addition, there is no special requirement for the shape of the slip control component 4, as long as it does not affect the subsequent slip after it breaks.

[0059] The above embodiments may be implemented individually or in any combination of two or more.
