Description

Technical Field

[0001] This invention relates to the field of building construction technology, and more specifically, to building partitions with a spliced ​​frame structure and construction methods. Background Technology

[0002] Building partitions, as key structures for dividing interior spaces and meeting the needs of different functional zones, directly affect the quality of building use. With the development of building industrialization and prefabrication, and the increasing demands for indoor acoustic environments, these partitions are becoming increasingly important.

[0003] Traditional masonry partition walls are heavy, involve a lot of wet construction, are inefficient, and are not conducive to flexible changes in the interior space of a building. Therefore, lightweight partition walls such as light steel keel gypsum board partition walls are currently more mainstream. Although these partition walls achieve dry construction and a certain degree of prefabrication, their frame structure is usually fixed in size, and the installation position of the keel is inconvenient to adjust, making it difficult to quickly adapt to non-standard size construction or later renovation needs. At the same time, the sound insulation performance of these partition walls generally relies on a single sound-absorbing material such as sound insulation cotton, which has limited ability to suppress low-frequency resonance. Furthermore, the low-frequency booming noise of elevator operation or equipment has strong penetrating power, and uniform density sound insulation materials are prone to overall resonance in the low-frequency range, which will aggravate the sound energy transmission and affect the acoustic comfort of living and working.

[0004] Therefore, a new solution is needed to address this problem. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a building partition wall with a spliced ​​frame structure and a construction method, which has the advantage of reducing the resonance phenomenon of low-frequency noise caused by the partition wall.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a building partition wall with a spliced ​​frame structure, comprising: The frame module is provided in several groups, each group including at least two uprights and horizontally arranged connecting members. A sliding groove is opened on the side of two adjacent uprights that are close to each other. The two sides of the connecting members are slidably connected in the sliding groove, so as to realize quick connection and fixation with the uprights at any height to form a grid. The functional module includes a first sound insulation board and a second sound insulation board, which are installed in the grid by interference fit or elastic clips. The second sound insulation board is set on both sides of the first sound insulation board. Several non-continuous air gaps are formed between the first sound insulation board, the second sound insulation board, the uprights and connecting components. The first sound insulation board is a high-density inorganic board material, which provides the main mass law sound insulation. The thickness of the air gaps is designed by adjusting the size of the frame module or the thickness of the functional module to generate a resonance dissipation effect for specific low-frequency noise. The decorative module includes at least one double-layer decorative panel. The back of the double-layer decorative panel is detachably connected to the surface of the upright via a snap-fit ​​device. There is a gap between the double-layer decorative panels, and several discontinuous elastic support blocks are fixedly connected within the gap.

[0007] The present invention is further configured such that: a plurality of damping mass blocks are embedded inside the first sound insulation board, the damping mass blocks are distributed in a non-uniform matrix in the first sound insulation board, and the distribution density is higher in the periphery of the first sound insulation board than in the center, so as to break the uniformity of the first sound insulation board, improve its overall rigidity and raise its natural frequency, and avoid strong resonance with the target low-frequency noise.

[0008] The present invention is further configured such that: the second sound insulation board is made of a gradient density porous flexible sound-absorbing material, the porosity of which varies in a gradient along the thickness direction, so as to broaden the sound absorption frequency band.

[0009] The present invention is further configured such that: a splicing module is provided between two adjacent sets of frame modules, the splicing module including a tenon and a groove with a complementary shape, the cross-sectional profile of the tenon being an asymmetrical polygon, to ensure that adjacent frame modules have a unique correct orientation when spliced ​​longitudinally.

[0010] The present invention is further configured such that: the double-layer decorative panel includes a substrate and a decorative panel, the elastic support block is disposed between the substrate and the decorative panel, the two opposite sides of the decorative panel are respectively provided with flanges and grooves, the flanges and grooves interlock with each other, and a sealing strip is provided at the interlocking point.

[0011] The present invention is further configured such that the elastic support block is made of a variable stiffness composite material, the stiffness of which increases nonlinearly with increasing pressure.

[0012] The present invention is further configured such that: the contact interface between the upright and the connecting member is provided with an elastic damping pad.

[0013] A construction method for building partition walls with a modular frame structure, used to construct building partition walls with a modular frame structure, includes the following steps: S1. Based on the design drawings, lay out lines on the ground and ceiling to determine the location lines of the partition walls and the center lines for the installation of the poles; S2, install several uprights vertically between the ground and the ceiling along the marked position, and initially fix them with the bottom and top fixing parts, and ensure that the grooves opened on the adjacent uprights are aligned. Take the connecting component, install elastic damping pads on the sliders on both sides of the connecting component, and according to the design height, align the sliders on both sides of several connecting components and insert them into the grooves of the two adjacent uprights and fix them to form a grid. S3. Align the asymmetrical polygonal tenon on the end post of the first set of frame modules with the complementary groove on the end post of the second set of frame modules, insert and push it in the only correct orientation to complete the mechanical interlocking and positioning between the frame modules. S4, take the second sound insulation board, with the high-density side of the second sound insulation board facing the sound source side, and embed and fix it from the grid side into the grid unit surrounded by the uprights and connecting members through interference fit or elastic clips. Take the first sound insulation board with the damping mass block embedded inside, make its edge contact with the uprights and connecting members, and embed it in the middle of the grid. Then repeat the installation of the second sound insulation board, so that the first sound insulation board is located between the two, and leave an air gap layer in it. S5, the substrate and decorative panel are spliced ​​together in advance, and an elastic support block is installed inside to obtain a double-layer decorative panel. The side closest to the substrate is installed on the upright through a snap-fit ​​device, and the edges of the two adjacent double-layer decorative panels are interlocked. S6. Check the connection strength, splicing tightness and sealing integrity of the installed building partition walls.

[0014] In summary, the present invention has the following beneficial effects: 1. The installation method of the uprights and connecting components can change the cumbersome process of traditional keel that requires precise pre-drilling or welding, and realize that the connecting components can be adjusted arbitrarily according to the height of the indoor space, which improves the installation freedom and on-site adaptability of the partition frame structure, and facilitates the adjustment of non-standard space dimensions and subsequent modification. Second, by arranging the damping mass blocks, the uniformity of the mass and stiffness distribution of the first sound insulation board is broken, which decomposes and disturbs its inherent overall vibration mode. This is equivalent to significantly raising the resonance frequency of the first sound insulation board, making it deviate from the common low-frequency noise bands of elevators and equipment operation, thereby effectively avoiding strong resonance transmission caused by frequency matching and minimizing the vibration radiation sound energy of the first sound insulation board itself. Third, by setting the porosity of the second sound insulation board to gradually change from the denser part on the sound source side to the looser inner layer, this gradient structure can match the penetration depth of sound waves of different frequencies, achieving more efficient sound absorption over a wider frequency band, especially for absorbing reflected sound waves of mid-to-high frequencies, forming frequency complementarity with the mass sound insulation of the first sound insulation board and the low-frequency resonance dissipation of the air layer.

Detailed Implementation

[0017] To enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other.

[0018] In the description of this invention, it should be noted that the terms "upper", "lower", "inner", "outer", "top / bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0019] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0020] Building partitions with a modular frame structure, such as Figures 1-6 As shown, it includes a frame module, a functional module, and a decorative module. The frame module is used to construct the outer frame of the building partition wall. Several sets are set up, and these sets can be spliced ​​together. The functional module and the decorative module are installed inside the frame module.

[0021] like Figure 1 and Figure 5As shown, the frame module is set in several groups, each group including at least two uprights 1 and horizontally arranged connecting components 2. Both the uprights 1 and the connecting components 2 are supported by high-strength light steel keel to ensure the lightweight and sturdiness of the overall structure. A sliding groove 3 is opened on the side of two adjacent uprights 1 that are close to each other. The two sides of the connecting components 2 are slidably connected in the sliding groove 3 to realize quick connection and fixation with the uprights 1 at any height to form a grid 4. The contact interface between the uprights 1 and the connecting components 2 is provided with elastic damping pads 17. The elastic damping pads 17 interrupt the rigid connection between the metal parts. Through its viscoelastic internal friction, the structural vibration energy propagating along the frame module is converted into heat energy dissipation, effectively suppressing solid-borne sound transmission and improving the overall sound insulation performance of the partition wall.

[0022] During construction, as described in S1, workers can divide the interior space according to the pre-designed drawings and directly align and insert the two sides of the connecting component 2 between two adjacent uprights 1. Alternatively, one end of the connecting component 2 can be connected to one of the sliding grooves 3 and fixed by the fasteners such as locking bolts and elastic pins built into the connecting component 2 before fixing and installing the other upright 1. This installation method can change the cumbersome process of pre-drilling or welding required by traditional keel, and realize that the connecting component 2 can be arbitrarily adjusted according to the height of the interior space, which improves the installation freedom and on-site adaptability of the partition frame structure, and facilitates the adjustment of non-standard space dimensions and subsequent modification.

[0023] To achieve the construction of partition walls with a larger area, splicing modules are set between two adjacent sets of frame modules. The splicing module includes a tenon 10 and a channel 11 with a complementary shape. The cross-sectional profile of the tenon 10 is an asymmetrical polygon to ensure that the adjacent frame modules have a unique correct orientation when spliced ​​longitudinally. After the splicing is completed, a sealing strip of the corresponding shape can be inserted into the channel 11 at the end and locked with fasteners such as bolts, so that the unused channel 11 can be flush with the surface of the column, ensuring that the edge of the building partition wall is flat.

[0024] like Figures 1-4 As shown, the functional module includes a first sound insulation panel 5 and a second sound insulation panel 6, which are installed in the grid 4 by interference fit or elastic clips. The first sound insulation panel 5 and the second sound insulation panel 6 are installed in the grid 4 enclosed by the uprights 1 and the connecting members 2, forming an embedded modular sound insulation structure. The first sound insulation panel 5 is made of high-density inorganic board, such as cement fiberboard or magnesium oxide board. The first sound insulation panel 5 mainly provides a basic sound barrier through the mass law, that is, the greater the surface density of the material, the stronger the ability to isolate airborne sound, thus laying the physical basis for blocking mid-to-high frequency noise.

[0025] To overcome the problem that traditional homogeneous sound insulation boards are prone to overall resonance in the low-frequency range, leading to a sharp decrease in sound insulation, the first sound insulation board 5 in this specification has several damping mass blocks 9 embedded inside. The damping mass blocks 9 are distributed in a non-uniform matrix within the first sound insulation board 5, and the distribution density is higher in the peripheral areas of the first sound insulation board 5 than in the central area. This breaks the uniformity of the first sound insulation board 5, improves its overall rigidity, and raises its natural frequency, avoiding strong resonance with the target low-frequency noise. The damping mass blocks 9 are usually high-density metal blocks, such as cast iron. The arrangement of the damping mass blocks 9 breaks the uniformity of the mass and stiffness distribution of the first sound insulation board 5, decomposing and disturbing its inherent overall vibration mode. This is equivalent to significantly raising the resonance frequency of the first sound insulation board 5, causing it to deviate from the common low-frequency noise bands of elevators, equipment operation, etc., thereby effectively avoiding strong resonance sound transmission caused by frequency matching and minimizing the vibration radiation sound energy of the first sound insulation board 5 itself.

[0026] The second sound insulation panel 6 is symmetrically installed on both sides of the first sound insulation panel 5. Several non-continuous air gaps 7 are formed between the first sound insulation panel 5, the second sound insulation panel 6, the uprights 1, and the sound insulation components. The thickness of the air gaps 7 is designed by adjusting the size of the frame module or the thickness of the functional module to generate a resonance dissipation effect for specific low-frequency noise. The aim is to make the air layer generate a resonance dissipation effect near the target frequency, converting sound energy into heat energy, thereby enhancing the low-frequency sound insulation performance. At the same time, the second sound insulation panel 6 is made of a gradient density porous flexible sound-absorbing material, such as gradient foam or gradient glass wool. Its porosity changes in a gradient along the thickness direction, gradually changing from a denser area on the side facing the sound source to a looser layer inside. This gradient structure can match the penetration depth of sound waves of different frequencies, achieving a wider frequency band of efficient sound absorption, especially for absorbing mid-to-high frequency reflected sound waves. It complements the mass sound insulation of the first sound insulation panel 5 and the low-frequency resonance dissipation of the air layer in terms of frequency. Finally, the entire functional module works synergistically.

[0027] like Figure 1 and Figure 6As shown, the decorative module includes at least one double-layer decorative panel. The back of the double-layer decorative panel is detachably connected to the surface of the upright 1 via snap-fit ​​fasteners. These fasteners can be spring clips, eccentric locks, etc. This connection method ensures convenient and secure installation between the double-layer decorative panel and the upright 1. More importantly, it allows for easy removal of the double-layer decorative panel during later maintenance of the partition wall without damaging its main structure. A gap 8 exists between the double-layer decorative panels, and several discontinuous elastic support blocks 18 are fixedly connected within the gap 8. The double-layer decorative panel includes a base plate 12 and a decorative panel 13. The elastic support blocks 18 are positioned between the base plate 12 and the decorative panel 13. The presence of the elastic support blocks 18 allows a spring layer supported by discrete elastic pads to be formed between the base plate 12 and the decorative panel 13. The base plate 12 can be made of gypsum board or calcium silicate board. The decorative panel 13 is the final surface layer that presents the aesthetic effect and can be made of various materials such as wood veneer, metal plate, or polymer-coated board.

[0028] Furthermore, the elastic support block 18 is made of variable stiffness composite material, and high-damping rubber can be selected. Its stiffness increases nonlinearly with increasing pressure. This stiffness is the dynamic pressure brought by the sound wave impact. Under static load or small amplitude vibration conditions, the elastic support block 18 exhibits a low initial stiffness, which can effectively isolate the transmission of vibrations over a wide frequency band, especially having a good attenuation effect on high-frequency vibrations. When the decorative panel 13 is subjected to strong impact or large-amplitude low-frequency vibration, the elastic support block 18 will experience greater compression, and its stiffness will increase significantly nonlinearly with the amount of deformation. This characteristic of changing from soft to hard primarily serves to limit excessive displacement of the decorative panel 13, ensuring its structural stability and integrity, and preventing the failure of the connecting component 2 or damage to the decorative panel 13. Secondly, maintaining sufficient dynamic stiffness under strong excitation helps to maintain the vibration isolation efficiency of the building partition wall against low-frequency vibrations, avoiding a decrease in sound insulation performance due to instability or breakdown under large amplitude. Therefore, the presence of the elastic support block 18 can adaptively isolate vibrations according to the vibration amplitude, further improving the sound insulation effect of the building partition wall.

[0029] The decorative panel 13 has a flange 14 and a groove 15 on opposite sides. The flange 14 and the groove 15 interlock with each other. During installation, the flange 14 can be embedded into the groove 15 to form a tight mechanical interlock, which can ensure that the surface of the decorative panel 13 is flat and aligned. A sealing strip 16 is provided at the interlocking point. The sealing strip 16 can fill the gap between the two and effectively prevent air from leaking through the gap.

[0030] A construction method for building partition walls with a modular frame structure, used to construct building partition walls with a modular frame structure, includes the following steps: S1. According to the design drawings, lay out lines on the ground and ceiling to determine the position lines of the partition wall and the installation center line of the pole 1; S2, install several uprights 1 vertically between the ground and the ceiling along the marked position, and initially fix them with the bottom and top fixing parts, and ensure that the grooves 3 opened on the adjacent uprights 1 are opposite. Take the connecting component 2, install elastic damping pads 17 on the sliders on both sides of the connecting component 2, and according to the design height, align the sliders on both sides of several connecting components 2 and insert them into the grooves 3 of the adjacent two uprights 1 and fix them to form a grid 4. S3, align the asymmetrical polygonal tenon 10 on the end post 1 of the first set of frame modules with the complementary groove 11 on the end post 1 of the second set of frame modules, insert and push it in the only correct orientation to complete the mechanical interlocking and positioning between the frame modules. S4, take the second sound insulation board 6, with the high-density side of the second sound insulation board 6 facing the sound source side, and embed and fix it from one side of the grid 4 into the grid 4 unit surrounded by the upright 1 and the connecting member 2 through interference fit or elastic clip. Take the first sound insulation board 5 with the damping mass block 9 embedded inside, and make its edge contact the upright 1 and the connecting member 2, and embed it in the middle of the grid 4. Then repeat the installation of the second sound insulation board 6, so that the first sound insulation board 5 is located between the two, and an air gap 7 is reserved in it. S5, the substrate 12 and the decorative panel 13 are spliced ​​together in advance, and an elastic support block 18 is installed inside to obtain a double-layer decorative panel. The side closest to the substrate 12 is installed on the upright 1 through a snap-fit ​​device, and the edges of the two adjacent double-layer decorative panels are interlocked. S6. Check the connection strength, splicing tightness and sealing integrity of the installed building partition walls.
