Description

Technical Field

[0001] The utility model relates to a buffer structure, in particular to a seismic isolation deformation buffer structure of adjacent buildings, and belongs to the technical field of building components. Background Art

[0002] When a building encounters natural disasters such as earthquakes, landslides, and hurricanes, it will swing, deflect, collapse, and fall. When the above situations occur, it will have a great impact on adjacent buildings, causing irreversible structural damage. In order to overcome the above problems, the prior art usually adopts a vibration reduction device with a spring between adjacent buildings to buffer the energy generated during the swinging process, such as a vibration reduction protection method for adjacent buildings disclosed in Chinese patent document No. CN 111779342B; but the defect of this patent is that the product has a relatively complex connection structure, and the installation process, especially the installation process in a high-altitude working environment, is relatively complicated; and because it has a complex transmission relationship, it is easy to malfunction under the influence of the external environment (such as rust, interference from debris causing jamming), resulting in reduced vibration reduction effectiveness, and frequent maintenance is also required. At the same time, it needs to be mass-produced by a factory, which is costly and has a long production cycle. Therefore, further improvement is needed. Utility Model Content

[0003] The purpose of the utility model is to solve the above-mentioned shortcomings and provide a seismic isolation deformation buffer structure for adjacent buildings, which has low production cost, convenient and fast construction, short production cycle and effectively shortens the construction period.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A seismic isolation deformation buffer structure of adjacent buildings comprises beams of two adjacent buildings; each of the beams is provided with a floor slab; each of the floor slabs is provided with a building surface layer, a connecting layer and a telescopic layer are provided between the building surface layers of the two adjacent buildings; the telescopic layer is fixed to the two beams by fasteners; and a buffer is also provided between the two beams.

[0006] Furthermore, an installation gap is formed between the building surface layer and the beam body; and a filling layer is also arranged between the connection layer and the expansion layer.

[0007] Furthermore, the two sides of the connecting layer, the filling layer and the telescopic layer are respectively embedded in two installation gaps of adjacent buildings; the connecting layer, the filling layer and the telescopic layer are stacked in sequence from top to bottom; and the surface of the connecting layer is flush with the building surface layer.

[0008] Furthermore, the connection layer is a flame-retardant plastic plate; the filling layer is an extruded plate; and the telescopic layer includes two stainless steel plates separated from each other.

[0009] Furthermore, there is a 30° bevel gap between the two stainless steel plates; the fasteners are first expansion bolts; and each of the stainless steel plates is fixed to the beam body by at least two first expansion bolts.

[0010] Furthermore, the buffer member includes an arched body; the arched body is elastically limited between two beams of adjacent buildings.

[0011] Furthermore, the buffer member also includes a fixed flange; the fixed flange is symmetrically arranged on both sides of the arch body; and the second fixed flange is connected to the beam body through expansion bolts.

[0012] The utility model has the following beneficial effects: the structure is arranged at the deformation joints (expansion joints, settlement joints, seismic joints, and seismic isolation joints) of the floor to meet the use function of the building structure, and can also serve as a decorative and beautiful device under the conditions of lower time and economic cost.

[0013] Specifically, it plays a covering and decorative role in terms of appearance; in terms of performance, it can adapt to expansion, settlement, seismic isolation and other functions, and meet the needs of deformation buffering of adjacent seismic isolation building floors. Construction personnel can make suitable building deformation joint devices on site according to the width of the deformation joint channel, which is low-cost and convenient and fast to construct. Traditional floor deformation joint devices are mass-produced by factories, with long production cycles and high costs. Compared with traditional products, this structure greatly shortens the construction period and reduces costs from production to construction and installation, while also reducing transportation costs. It is a better choice for engineering projects with tight construction periods. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] A seismic isolation deformation buffer structure for adjacent buildings comprises beam bodies 1 of two adjacent buildings; each of the beam bodies 1 is provided with a floor slab 2; each of the floor slabs 2 is provided with a building surface layer 3, and a connecting layer and a telescopic layer are provided between the building surface layers 3 of the two adjacent buildings; the telescopic layer is fixed to the two beam bodies by fasteners; and a buffer is also provided between the two beam bodies 1.

[0020] Furthermore, an installation gap is formed between the building surface layer 3 and the beam body 1; and a filling layer is also provided between the connection layer and the expansion layer.

[0021] Furthermore, the two sides of the connection layer, the filling layer and the expansion layer are respectively embedded in two installation gaps of adjacent buildings; the connection layer, the filling layer and the expansion layer are stacked in sequence from top to bottom; and the surface of the connection layer is flush with the building surface layer 3.

[0022] Furthermore, the connection layer is a flame-retardant plastic plate 4; the filling layer is an extruded plate 5; and the telescopic layer includes two stainless steel plates 6 separated from each other.

[0023] In this embodiment, a flame retardant plastic plate 4 and an extruded plate 5 are arranged on the surface of the telescopic layer as a covering surface, which can play a role in fire retardancy. When the building swings due to natural disasters such as earthquakes and hurricanes, the flame retardant plastic plate 4 and the extruded plate 5 will break; and the two stainless steel plates 6 are separated from each other, so when the flame retardant plastic plate 4 and the extruded plate 5 break, the two stainless steel plates 6 can adapt to the swing of the building and provide a telescopic space for it, which can also provide displacement space for buffering. Buffering is mainly achieved through buffering parts, as follows.

[0024] Specifically, the filling layer preferably adopts a 50 mm thick extruded board 5; the connection layer preferably adopts a non-slip treated flame-retardant plastic board 4; and the telescopic layer preferably adopts a 15 mm thick stainless steel board.

[0025] Furthermore, there is a 30° bevel gap between the two stainless steel plates 6 ; the fasteners are first expansion bolts 7 ; and each of the stainless steel plates 6 is fixed to the beam body by at least two first expansion bolts 7 .

[0026] Furthermore, the buffer member includes an arched body 8; the arched body 8 is elastically limited between the two beam bodies 1 of adjacent buildings.

[0027] Furthermore, the buffer member further comprises a fixed flange 9 ; the fixed flange 9 is symmetrically arranged on both sides of the arch body 8 ; the fixed flange 9 is connected to the beam body 1 through a second expansion bolt 10 .

[0028] In this embodiment, the arched body 8 is preferably made of 1 mm thick iron sheet and is treated with rust and fire prevention. When the building sways, the arched body 8 will deform, and the elasticity of the arched structure and the iron sheet material will be used to buffer and absorb energy.

[0029] The radius of the arch body 8 is R=L / 2, where L is the maximum displacement of adjacent seismic isolation buildings in rare earthquakes, and L=500-700 mm.

[0030] This solution meets the requirements of relevant national and regional specifications and standards such as the "Standard for Seismic Isolation Design of Buildings" (GB / T51408-2021) and the "Technical Code for Fire Protection of Building Steel Structures" (GB 51249-2017). Scope of application: Buildings that use seismic isolation technology, such as primary and secondary schools, hospitals, commercial complexes, and residential buildings (large, medium, and small).
