Referring to fig. 1 to 19, in one embodiment of the present invention, a high sound insulation integrated fabricated wall structure includes:
at least three keel frames 100 stacked together, wherein the keel frames 100 comprise frame-shaped plate portions 110 and frame-shaped bone portions 120, the bone portions 120 are connected to the inner side of the plate portions 110 in the circumferential direction, and a plurality of plate wall cavities 130 are formed by arranging the bone portions 120 at intervals in the thickness direction of the whole keel frame 100;
a plurality of main keels 200 arranged at intervals in the horizontal direction, wherein the main keels 200 are fixed at the upper and lower ends of the bone part 120;
the auxiliary keels 300 are arranged at intervals in the vertical direction, and the auxiliary keels 300 transversely penetrate through the thickness direction of the main keels 200;
the plurality of inner wall board layers 400 are respectively arranged in the board wall cavity 130, a plurality of first hanging pieces 410 are arranged on one side surface of the inner wall board layers 400, a second hanging piece 420 which is in hanging fit with the first hanging pieces 410 is arranged on the auxiliary keel 300, a plurality of supporting tongues 210 which are used for supporting the inner wall board layers 400 are arranged on the main keel 200 corresponding to the smooth surface of the inner wall board layers 400 in the height direction, and one side of the inner wall board layers 400 provided with the first hanging pieces 410 is abutted against the main keel 200;
The two outer wall plate layers 500, wherein a plurality of third hanging pieces 510 are arranged on the inner side of the thickness direction of the outer wall plate layer 500, fourth hanging pieces 520 which are in hanging fit with the third hanging pieces 510 are arranged on the auxiliary keels 300 on the outer two keel frame 100, and the inner side surface of the outer wall plate layer 500 is abutted against the main keels 200 at the corresponding positions;
wherein the high sound insulation integrated fabricated wall structure is provided with a damping layer 700 on at least seventy percent of an interface in a thickness direction.
In the invention, the integral thickness of the high sound insulation integrated assembly type wall structure body is about 12 cm to 25 cm, and the wall structure body can be thinned and thickened under some special requirements. The high sound insulation integrated fabricated wall structure includes at least three stacked joist frames 100, preferably 3 to 4. First, the specific structure of the plurality of keel frames 100 is not limited to be completely uniform, and may be different in detail in consideration of the fixing effect and the like. The plurality of keel frames 100 are not limited to a split structure in the thickness direction, and may be an integral structure. The plurality of keel frames 100 may be arranged at intervals (the whole wall thickness can be increased, and the sound insulation effect is improved) in the thickness direction, or may be partially overlapped (the whole wall thickness is reduced, the structural rigidity is high, and the installation process can be performed synchronously to a certain extent). For example, if the three keel frames 100 are partially overlapped in the thickness direction of the plate portion 110, then the three keel frames 100 form structural supports therebetween, and during installation, the process of securing the keel frames 100 to the external foundation may be accomplished at the overlapped portions of the plate portion 110 using securing structures such as expansion screws; during the above fixing process, structural fixing is also formed between the keel frames 100. The fixing mode of the keel frame 100 can be referred to the conventional section mode in the existing common building field. The keel frame 100 is frame-shaped, and can be an integral structure or a connecting structure in the circumferential direction, and if the connecting structure is the number of the connecting points related to the connecting structure, the number is selected according to the convenience of production or installation; that is, the plate portion 110 and the bone portion 120 also have the above-described characteristics in the circumferential direction. The plurality of bone portions 120 are spaced apart in the thickness direction of the overall keel frame 100 to form a plurality of panel cavities 130, providing room for the subsequent installation of the interior wall panel layer 400. For example, the keel frame 100 includes two cross runners 140 and two side runners 150 that are in turn interconnected to form a frame structure, and the entire high acoustic insulation integrated fabricated wall structure can be extended in a wide range of dimensions in either the horizontal or vertical directions by length sizing or lengthwise splicing of the cross runners 140 and side runners 150.
The main keels 200 are disposed at intervals (for example, 30 cm to 60 cm) in the horizontal direction, and the main keels 200 are fixed to the upper and lower ends of the bone parts 120, thereby realizing the integral connection with the keel frame 100. The main runner 200 provides a mounting foundation for the subsequent cross runner 300. The thickness direction of the main runner 200 may partially overlap, completely overlap, or completely overlap with the thickness direction of the runner frame 100; with specific reference to structural strength and ease of installation, partial overlap and complete overlap are preferred. The main joist 200 may be variously shaped, for example, the cross section of the main joist 200 is generally in an i-shape, and two ends of the main joist 200 in the height direction form a snap-fit with the bone 120 at the corresponding position in the cross section.
The plurality of cross runners 300 are disposed at spaced intervals in the vertical direction, and the cross runners 300 are disposed transversely across the thickness of the plurality of main runners 200. The plurality of cross runners 300, in addition to providing a structure between the plurality of main runners 200 such that the cross runners 300 and the main runners 200 together form a stable foundation grid structure, the cross runners 300 also provide a fixed foundation for the subsequent interior and exterior wall cladding layers 400, 500. It should be noted that, the cross runners 300 may be sectioned in the length direction, that is, the cross runners 300 include a plurality of sub-cross runners 300, and specific sub-cross runners 300 may be connected to each other or simply arranged in sequence in the length direction (even with a spacing in the length direction).
The plurality of inner wall panel layers 400 are respectively disposed in the wall cavities 130, for example, the number of the wall cavities 130 is two, and the number of the inner wall panel layers 400 is also two, and the characteristics such as the thickness and the material of the inner wall panel layers 400 are not limited to be uniform. A plurality of first hitches 410 are provided on one side of the inner wall panel layer 400, and a second hitches 420, which form a hitching fit with the first hitches 410, are provided on the cross runner 300. The first hanging members 410 on the inner wall panel layer 400 may be arranged in a rectangular array or other arrangement modes, specifically, the hanging process of the inner wall panel layer 400 is facilitated, and the second hanging members 420 on the corresponding auxiliary joists 300 are arranged in positions corresponding to the first hanging members 410. The length of the first and second hitches 410, 420 extending along the length of the cross runner 300 may be varied, typically about 15 cm, and one of the first and second hitches 410, 420 may be male and the other female, so as to form a hitch for plugging. The side of the inner wall panel layer 400 provided with the first hooking member 410 is abutted against the main runner 200 of the runner frame 100 where the inner wall panel layer 400 is hung, so that structural stability of the inner wall panel layer 400 is ensured. The thickness of the inner wall panel layer 400 cannot be equal to the thickness of the panel wall cavity 130, but is formed with a mounting gap cavity; the inner wall panel layer 400 is abutted against only one side of the main joist 200, otherwise the sound transmission channels are too many to be good for the sound insulation effect; the creation of the installation clearance cavity is achieved in the present invention by the presence of the abutment tongue 210. The main runner 200 corresponding to the smooth surface (the surface without the first hitching member 410) of the inner wall panel layer 400 is provided with a plurality of abutment tongues 210 in the height direction for abutting against the inner wall panel layer 400, and the inner wall panel layer 400 is supported by the abutment tongues 210, and the arrangement of the abutment tongues 210 greatly reduces the area of the sound bridge. The two surfaces of the inner wall panel layer 400 in the thickness direction are respectively abutted by the main joist 200 on one side and the abutment tongue 210 on the main joist 200 on one side. The manner in which the abutment tongue 210 is specifically formed may be post-assembled (e.g., by bolts or rivets, etc.) to the main runner 200 or may be integrally formed with the main runner 200 (as will be further described in the following embodiments). The inner wall panel layer 400 is a 20 mm and 8 mm thick board (gypsum board, cement board, glass magnesium board, fiberboard, etc.), respectively. The arrangement interval of the abutting tongue 210 in the height direction is designed according to the actual situation, and the less the number of the fixing effect is secured, the more excellent the effect of enhancing the sound insulation effect is similarly to the first hitching member 410. The abutment tongue 210 may have a plate shape, a columnar shape, or the like, and is preferably a plate shape having a small contact area with the inner wall panel layer 400 while providing a good structural support.
The two exterior wall board layers 500 are respectively disposed on the outer sides of the thickness direction of the high sound insulation integrated assembly type wall structure, and the particular exterior wall board layer 500 may be a decorative wall (at this time, the high sound insulation integrated assembly type wall structure is already a complete structure without appearance decoration) or a functional wall (at this time, a decorative structure such as wallpaper, wall bricks or wall boards is also required to be disposed on the exterior wall board layer 500). The exterior wall panel layers 500 are each a board (gypsum board, cement board, glass magnesium board, vitamin board, wood board, etc.) having a thickness of about 10 mm. The inner side of the outer wall plate layer 500 in the thickness direction is provided with a plurality of third hanging members 510, the auxiliary keels 300 on the outer two keel frames 100 are provided with fourth hanging members 520 which form hanging fit with the third hanging members 510, and the hanging structure of the specific outer wall plate layer 500 and the hanging structure of the inner wall plate layer 400 can be the same, and are not described in detail herein. Of course, the exterior wall panel layer 500 has a certain sound insulation effect even when it is a decorative wall panel. In the invention, on the premise that sound absorption filling is not added in the wall body, a high-quality sound insulation effect is realized, and particularly, a plurality of air cavities capable of improving the sound insulation effect are generated in the thickness direction of the assembled wall structure. Related functional structures such as junction boxes, network components, video and audio components, light effect components, pipelines, cables, storage boxes and the like can be integrally arranged in the air cavity. The above functional structures are disposed in the air chamber, and the fixed basis of the functional structures may be the keel frame 100, the main keel 200, the auxiliary keel 300, the inner wall ply 400, the outer wall ply 500, etc. (may be pre-installed) of the high sound insulation integrated fabricated wall structure. The remaining space may be filled with some sound absorbing material as needed. Skirting lines, decorative sealing strips and the like may be preset at corresponding positions of the wallboard layer 500, thereby reducing subsequent finishing installation steps.
The above inner and outer wall panel layers 400 and 500 are not limited to the integral structure, and may be a splice structure in both horizontal and vertical directions, and the less the splice is, the better the sound insulation effect is. There are two kinds of joint processing methods for the above exterior wall ply 500 or interior wall ply 400: firstly, the dimensional accuracy of the split sub-structure is greatly improved, and the split joint is removed from the aspect of physical dimension; second, a sealing filler such as a damping layer or a filler glue is provided at the relevant seam location.
In various embodiments, the assembled wall structure has a thickness ranging from 12 cm to 25 cm, using 8 mm and 20 mm plasterboard as the two interior wall plies 400, using 10 mm decorative board as the exterior wall ply 500, the bone 120 has a thickness of about 20 mm, the cavity 130 has a thickness of about 30 mm, and the final sound insulation test is up to 50 db or more, each approximately 60 db. Specifically, for the scenes with different requirements on sound insulation, the model and/or the thickness direction interval of the keel frame 100 and the surface density of the outer wall plate layer 500 and/or the inner wall plate layer 400 can be selectively adjusted, the influence on the overall structural design of the high-sound-insulation integrated assembly type wall structure is small, and the flexibility of design, the flexibility of application and the flexibility of performance are high. In specific implementation, the typical performance parameter requirements of 40 db, 45 db, 50 db, 55 db and 60 db can be realized by adjusting the relevant parameters. For some extreme sound insulation requirements, the number of layers of the keel frame 100 may be increased or the areal density of the interior wall panel layer 400 may be increased accordingly.
Before describing the function of the damping layer 700, taking the case of three keel frames 100 as an example, the noise transmission manner is uniform from both sides of the fabricated wall structure, and the middle-layer subsidiary keel 300 is formed at the most middle part of the thickness direction of the fabricated wall structure, then the contact sound transmission channel (sound bridge) from one side outer wall plate layer 500 to the middle-layer subsidiary keel 300 is analyzed. There are two types of contact-to-microphone channels:
the vibration of the third hitches 510 on the first and outer wall plies 500, to the fourth hitches 520, to the side cross runners 300 corresponding to the fourth hitches 520, to the outer main runner 200, to the abutment tongue 210 on the outer main runner 200, to the inner wall plies 400, to the first hitches 410 and the inner main runner 200, and then to the first hitches 410 sections is transferred to the second hitches 420 and the middle cross runner 300 in sequence;
the vibrations of the second, outer wall ply 500 to the outer main runner 200, to the abutment tongue 210 on the outer main runner 200, to the inner wall ply 400, to the first hanger 410 and the inner main runner 200, and then to the first hanger 410 portion are transferred to the second hanger 420 and the middle cross runner 300 in sequence.
Through the analysis of the above sound transmission channels, the overall sound transmission channels are complex and have small sound transmission areas, and all the sound transmission channels pass through the abutting tongues 210, at this time, the sound transmission channels are contracted into a plurality of abutting tongues 210 and form a plurality of linear contact surfaces with the inner wall plate layer 400, and then the contact area of the sound bridge is greatly reduced.
Specifically, the high sound insulation integrated assembly wall structure is provided with the damping layer 700 at the interface of at least seventy percent in the thickness direction, and the sound insulation effect is better as the above ratio is higher, and the sound insulation effect may not reach the standard if it is too low. In the present invention, there is no sound absorbing material filling, and the sound insulation effect is achieved by the inner wall ply 400, the outer wall ply 500, and the unfilled panel wall cavity 130. The damping layer 700 interrupts the sound transmission channel in multiple in the thickness direction, and of course, the damping layer 700 has the effects of structural sealing and structural buffering as well. It is possible here to analyze in particular the sound transmission channel in the thickness direction:
1. when the keel frame 100 is an assembled structure, the contact surfaces are assembled in the thickness direction;
2. the interface of the cross runner 300 with the main runner 200;
3. the interface of the inner wall panel layer 400 with the main runner 200 and the keel frame 100 at the corresponding locations;
4. the contact surface of the inner wall panel layer 400 with the first hitching member 410, the contact surface of the false keel 300 with the second hitching member 420, and the contact surface of the first hitching member 410 with the second hitching member 420;
5. an interface against the tongue 210 and the inner wall ply 400;
6. the contact surfaces of the exterior wall ply 500 with the main runner 200 and the runner frame 100 at the corresponding locations;
7. The contact surface of the exterior wall ply 500 with the third hitching member 510, the contact surface of the false keel 300 with the fourth hitching member 520, and the contact surface of the third hitching member 510 with the fourth hitching member 520.
In the high sound insulation integrated fabricated wall structure, the damping layer 700 is disposed on the above contact surface to interrupt the sound transmission channel as much as possible, so that the sound insulation effect of the high sound insulation integrated fabricated wall structure is improved. The specific method of processing the damping layer 700 is preferably pre-processing, but may be in-situ processing, and the method of pre-processing the damping layer 700 may be bonding, coating, or the like. The damping layer 700 may be made of various materials, such as rubber damping, asphalt damping, plastic damping, resin damping, etc., and inorganic fireproof or waterproof paint may be selected from the viewpoint of functions, so as to meet the requirements of fireproof, environmental protection and shock absorption.

The structures of the two cross runners 140 may be identical or may have some minor differences; the two sets of side runners 150 may be identical in construction or may have some minor differences. The keel frame 100 is assembled in four separate mechanisms (two cross runners 140 and two side runners 150) to provide a convenient way. In the installation process, the installation sequence of the transverse keels 140 and the side keels 150 is not limited, and the adjustment is carried out according to actual conditions. It should be noted that, the cross runner 140 and the side runner 150 are preferably formed by extrusion, and the detailed structures of the cross runner 140 and the side runner 150 may be modified after extrusion for tightness of the split between them.
In one embodiment, the main runners 200 are offset in a horizontal direction from the various ones of the keel frames 100.

In this embodiment, since a plurality of air cavities capable of improving the sound insulation effect are generated in the thickness direction of the assembled wall structure, relevant functional structures (such as a junction box, a network component, an audio-visual component, a light effect component, a pipeline, a cable, a storage box and the like) can be integrally arranged in the air cavities. The provision of a fixed base structure provides a mounting base for the above functional structure. The mounting locations of the fixed base structure may be the keel frame 100, the main keel 200, the cross runners 300, the interior wall cladding 400, the exterior wall cladding 500, etc. of the high sound insulation integrated fabricated wall structure (either preassembled or field flexibly installed).

In this embodiment, taking the inner wall plate layer 400 as an example, when the inner wall plate layers 400 are made of the same material, the difference in the surface density is formed by forming the difference in the thickness of two adjacent inner wall plate layers 400 in the thickness direction, so as to reduce the noise transmission generated by resonance between the two. For example, the two inner wall panel layers 400 are respectively 20 mm and 8 mm thick boards (gypsum board, cement board, magnesium board, etc.). When the materials of the inner wall plate layers 400 are different, the densities themselves are different, and then the improvement of the surface density difference is realized through thickness adjustment, so that noise transmission generated by resonance between the two layers is reduced.

The cross section shape can be selected from Chinese character 'ri' shape, chinese character 'mu' shape, etc. By improving the structural strength of the cross runners 300, the spacing of the cross runners 300 in the vertical direction may be increased from a conventional 60 cm to about one meter, i.e., reducing the overall number of applications for the cross runners 300.
