Description

Indoor sound insulation structure independent of external environment

Technical Field

The present invention relates to an indoor sound insulation structure independent of an external environment.

Background

With the increase of the open work space, the privacy required in the work space is affected, workers are required to design a quiet and private area in the open work space, in which one or more persons can concentrate on work or thinking, or discussion without interference, and can also make or receive a video call without affecting the work of surrounding persons due to noise generated by the phone or video call or discussion, and the above design purpose can be achieved by a sound insulation structure. The sound insulating construction may be defined as a small indoor building construction, or may be defined as a piece of public furniture, primarily for use in a public office space, a public service space, or a public business space. Typically with a closed door frame and leaf assembly, a fixed window assembly, a wall assembly, and a top and bottom assembly accessible by the user. The sound insulation and sound absorption type indoor sound insulation and absorption device can be usually disassembled and assembled for many times, and can provide a private space for inside and outside sound insulation and inside sound absorption for one or more people in an indoor open environment. Typical uses are indoor kiosks, indoor movable sound-insulated workshops, indoor movable meeting rooms, etc. that provide sound-insulated spaces in open environments.

Such a sound insulation structure is a small indoor building constructed according to the requirements of building physics, and it is necessary to satisfy not only a relatively high sound insulation requirement but also functions required for comfortable use, such as ventilation, sound absorption, and the like, which are very likely to impair sound insulation performance.

It is known that the sound insulation performance of a sound insulation structure depends on the combination of the sound insulation performance of the sound insulation structure and the sound insulation performance of sound in different frequency bands, and the sound insulation structure with good sound insulation performance is difficult to construct by using a single material with a single density, and the sound insulation performance is easy to achieve by adopting a plurality of materials with different densities to compositely construct the sound insulation structure.

Because the space planning and the space arrangement of the open working space are often adjusted, the arrangement position of the sound insulation structure is required to be adjusted according to the new space planning and arrangement requirements when necessary, and therefore the sound insulation structure can be remounted after being disassembled and moved for a plurality of times without affecting the sound insulation performance.

Removable sound insulation constructions often include a top assembly, a bottom assembly, a wall assembly, and a door assembly, wherein the wall assembly generally includes a plurality of interconnected cavities. Because the components adopt various composite materials for good sound insulation performance, and the composite materials are materials with sound insulation or sound absorption performance, such as plywood, a PET sound absorption plate and the like, the materials do not have precise processing conditions, the wall components are formed by the materials which are not easily processed by precise processing, the precision of door frame and door leaf components and fixed glass window components can be generally measured only by the requirements of building components, the components are easily combined together to have errors of a few millimeters, and the positions and the sizes of the errors have certain randomness. In order to meet the requirement of high sound insulation inside and outside, the weight of each component of the sound insulation structure reaches dozens of kilograms, the assembled sound insulation structure is often hundreds of kilograms, and the sound insulation structure for a single person is generally 300 to 400 kilograms. The assembly of the sound insulation structure is assembled, used and disassembled for many times, random deformation errors can be generated due to the deformation of materials in the assembling and disassembling processes of the assembly of the sound insulation structure, and the errors objectively existing in the modular assembling mode and the manufacturing process of each module exist, so that the combined surface between the assemblies of the sound insulation structure is easy to insulate sound and lose efficacy due to the random errors. In particular, the problem of failure of sound insulation due to deformation of the material during repeated mounting and dismounting is difficult to solve with the sound insulation structure of the conventional structure.

Detailed Description

The invention is described in detail below with reference to the following figures and embodiments:

the utility model provides an indoor sound insulation structure independent of external environment, includes top subassembly 400, bottom subassembly 500, wall subassembly 610 and door subassembly 200, or still includes window subassembly 300, and the face of being connected that carries out with other subassemblies in each subassembly all comprises a plank, and in the subassembly that contains a plurality of faces of being connected, every is connected face and connects each other through mortise and tenon structure 920, sets up two sets of location pinhole combination 801 and two sets of bolted connection 901 on interconnect's the face of being connected between each subassembly at least.

As shown in fig. 2 and 6, the top module 400, the bottom module 500 and the two side wall modules 610 are not only connected to the door module 200, but also connected to the window module 300 or another wall module instead of the window module 300, and the two side wall modules 610 are also connected to the top module 400 and the bottom module 500 at the same time, so that the top module 400, the bottom module 500 and the two side wall modules 610 include a plurality of connection surfaces, and in each module, the connection surfaces are connected to each other through the mortise and tenon structure 920, so that the connection surfaces can obtain higher structural strength when only wood is used as a main structure, the size deformation and error of the connection surfaces can be reduced, and the connection surfaces are not easily deformed even if being disassembled and assembled for many times. While the door assembly 200, the window assembly 300, or another wall assembly instead of the window assembly 300 has only one connection surface that is connected to both the top assembly 400, the bottom assembly 500, and the two side wall assemblies 610.

Obviously, in the indoor sound insulation structure, the structure and the position relation between the top assembly, the bottom assembly, the wall assembly, the door assembly and the window assembly are not limited to the above form, and there may exist a structure form that the top assembly and/or the bottom assembly have only one connection surface, and the wall assembly, the door assembly and the window assembly have a plurality of connection surfaces, and other structure forms that cannot be listed.

As shown in fig. 6, at top subassembly 400, set up two sets of location pinhole combination 801 and two sets of bolted connection 901 on interconnect's the connection face between bottom subassembly 500 and the wall subassembly 610 of two both sides at least, also set up the same location structure and connection structure on the connection face of other subassemblies, location pinhole combination 801 can make each subassembly pinpoint when the equipment, avoid the equipment error, and bolted connection 901 can be at the in-process of bolt tightening, the shape defect and the error of connecting the face can be eliminated to a certain extent to the strength of bolt tightening, make two connect the face take place the deformation of certain degree, thereby make two connect the face and laminate as far as possible, strengthen two leakproofness of connecting the face and connecting.

Therefore, in the invention, the mortise and tenon structure provides structural strength for the connecting surface of the assembly, the positioning pin hole combination provides accurate positioning for the installation of the assembly, and the bolt connection can eliminate the error of the connecting surface, so that the indoor sound insulation structure cannot cause sound insulation failure due to shape error in the installation process. Moreover, in the repeated dismounting process, the mortise and tenon structure enables the assembly to be not easy to deform, the positioning pin holes can always conveniently position the connection of the assembly, and the bolt connection can eliminate the slight deformation of the assembly in the dismounting process, so that the indoor sound insulation structure can also ensure the sound insulation effect in the repeated dismounting process.

As a preferred structure, in an assembly including a plurality of connection surfaces, the connection surfaces form a frame structure through the mortise and tenon structure 920, and a bolt passes through the connection surfaces from the non-contact side of the connection surfaces to be connected with another connection surface. Referring to fig. 6, the top assembly 400, the bottom assembly 500 and the wall assembly 610 all include a plurality of connecting surfaces, and in each assembly, a frame structure is formed between the connecting surfaces through a mortise and tenon structure 920, so that the structural strength of the whole assembly is ensured. Meanwhile, the frame structure is convenient for bolts to penetrate through the connecting surfaces to connect the two connecting surfaces together.

As shown in fig. 7, a concrete material structure of the top assembly 400 is a PET sound-absorbing panel 401, a sound-absorbing sponge 402, a multi-layer panel 403 and an exterior sound-insulating steel panel 701 from the inside to the outside of the sound-insulating structure. The PET sound absorption board 401 and the sound absorption cotton 402 both have a sound absorption effect, the multilayer board 403 and the exterior sound insulation steel plate 701 both have a sound insulation effect, and the sound insulation and absorption structure of the top component can realize sound insulation and sound absorption of the top component, so that the sound insulation structure has an excellent sound insulation effect. Especially, the two-layer sound absorption structure close to the interior of the sound insulation structure can prevent the noise of conversation, telephone and the like of a user in the sound insulation structure from being conducted to the outside, and ensure that the sound activity of the indoor sound insulation structure can not influence the external environment.

As shown in fig. 8, the wall component 610 is a multilayer sound absorption and insulation composite structure, and comprises a PET sound absorption plate 401, a multilayer plate 403, sound absorption cotton 402, a sound insulation steel plate 404, sound absorption cotton 402, a multilayer plate 403 and an exterior decoration sound insulation steel plate 701 in sequence from inside to outside of the sound insulation structure. The 4-layer sound insulation and 3-layer sound absorption composite structure ensures good sound absorption and sound insulation performance of the sound insulation structure. Sound insulation and absorption treatment of the sound insulating construction wall panel assembly is particularly important since noise in the sound insulating construction occurs primarily within the height range of the sound insulating construction wall assembly and the user's perception of comfort of the acoustic environment inside the sound insulating construction is also primarily concentrated within this height range. The multilayer sound absorbing and insulating composite structure adopted by the wall component 610 can meet the sound insulating and absorbing requirements of a sound insulating structure.

As shown in fig. 9, the bottom assembly 500 is composed of a sound-proof structure, from inside to outside, a carpet 405, a multi-layer board 403, a sound-absorbing cotton 402, a multi-layer board 403, and an exterior sound-proof steel plate 701. The carpet 405 also provides sound absorption while the multi-layer panel 403 abutting the carpet 405 provides support and sound insulation, and is otherwise identical to the top assembly 400.

The top assembly 400, the wall assembly 610 and the exterior sound insulation steel plate 701 outside the bottom assembly 500 are structured as shown in fig. 2, and the whole periphery of the sound insulation structure is wrapped by one circle, so that not only sound insulation effect but also decorative effect can be achieved. The exterior sound insulation steel plate 701 can be adsorbed on each component through magnets, and the installation is convenient and fixed. The components of the sound insulation structure are discontinuous and discontinuous due to the requirements of internal structure and function, and have some blind points and weak points for sound insulation treatment.

As shown in fig. 6, the sound insulation structure further includes an electric device 570 and a network device 580 installed in the bottom assembly 500, and is surrounded by the sound insulation multilayer board to insulate the operation noise of the devices, reducing the influence of the devices on the sound insulation structure and the sound insulation effect of the whole sound insulation structure.

As shown in fig. 2, the door assembly 200 includes a door frame 230 and a door leaf 210, the door frame 230 is a door frame integrated by laminating adhesive and adopting plywood and a fireproof plate, the door leaf 210 includes a door leaf frame and glass, and the door leaf frame is an integrated door leaf frame glued by adopting plywood. The sound insulation structure can adopt a relatively heavy sound insulation door in order to achieve a relatively good internal and external sound insulation effect, but the door frame assembly of the sound insulation structure is assembled on the whole sound insulation structure by an assembly type method, so that the door frame of the integrated type is adopted, the door frame can achieve high strength, the door leaf is not easy to cause loose deformation of the door frame after being opened and closed repeatedly, and the durability of the door frame is improved. The door frame 230 and the door leaf frame are made of a multi-layer composite material, and have stronger bearing weight and deformation resistance, thereby not only ensuring the structural stability of the door assembly and the window assembly and the overall structural stability of the sound insulation structure, but also ensuring the sound insulation performance of the door assembly and the window assembly and the sound insulation performance of the sound insulation space obtained by combining the door assembly and the window assembly with other assemblies.

With reference to fig. 2 to 5, four corners of the door leaf frame are rounded. The design of the four-corner round corners can improve the structural stability of the door leaf and resist the deformation possibly generated due to stress in use. The sound insulation performance of the entire door assembly is increased. Since the door leaf frame is designed to have four rounded corners, the door leaf 210 on one side of the handle presses against the plane of the door frame 230 when the door is closed, as shown in fig. 4; and one side of the hinge, leaf 210, is pressed against the facade of the door frame 230, fig. 5. The vertical surface gap between the door frame 230 and the door leaf 210 is about 5mm, the plane gap is about 2mm, and the four corners of the door leaf adopt the round angle design, so when the door leaf 210 and the door frame 230 are combined by the hinge, the sealing strip 220 between the door leaf 210 and the door frame 230 can be smoothly curved in an arc shape along with the arc-shaped bending of the door leaf 210 without influencing the sound insulation performance, therefore, the sealing strip between the door leaf 210 and the door frame 230 can meet the requirement by being designed into a long round shape, and the sound insulation between the door leaf 210 and the door frame 230 is ensured.

As shown in fig. 4 and 5, the door leaf 210 has a glass strip 240 between the door leaf frame and the glass to increase the sealing performance of the door leaf 210, and this structure can also be used in the window assembly 300.

Fig. 10 is an overall schematic view of a second embodiment of the present invention, which is different from the first embodiment in that the shape of the door assembly 200, particularly the door leaf 210, is changed. Fig. 11 is an overall schematic view of a third embodiment of the present invention, in which the overall size is changed, and the size and number of components are changed accordingly, so as to accommodate more people.
