Description

Technical Field

[0001] The present invention relates to a sound absorption and insulation pad and an installation method thereof. Background Art

[0002] Sound waves are a form of propagation generated by sound using air as a medium. When sound waves encounter an obstacle, they will be divided into three parts: 1. The first part of the sound wave will be reflected by the obstacle to form a reflected sound wave; 2. The second part of the sound wave will be absorbed by the obstacle and thus directly disappear; 3. The third part of the sound wave will pass through the obstacle and enter the space behind the obstacle.

[0003] Existing residential buildings have multiple residences. When residents live in their residences, various sounds will be generated, such as: sounds generated by residents' activities, sounds generated by small kitchen appliances working, sounds generated by audio and video playback devices working, sounds generated by sewer drainage, etc.

[0004] To eliminate sound waves, many sound absorption and insulation pads have emerged on the market. Taking one example of eliminating the sound generated by drain pipe drainage: users usually wrap a layer of sound absorption and insulation pad outside the sewer, and the sound absorption and insulation pad needs to be adhesively connected end to end at the construction site with an adhesive.

[0005] However, adhesively connecting the sound absorption and insulation pad end to end at the construction site with an adhesive has the following disadvantages: 1. Construction workers, in order to save the construction time of a single sound absorption and insulation pad, make the end-to-end pasting of the sound absorption and insulation pad not in place; 2. There is a certain probability that the sound absorption and insulation pad will be damaged during transportation, resulting in the end-to-end adhesive connection of the sound absorption and insulation pad not being in place; 3. At the construction site of the sound absorption and insulation pad, construction workers need to prepare the adhesive additionally. When too little adhesive is prepared, construction workers may reduce the amount of adhesive at the end-to-end adhesive connection of a single sound absorption and insulation pad. All in all, there is still room for improvement in the structure of the sound absorption and insulation pad at its adhesive connection. Summary of the Invention

[0006] The problem to be solved by the present invention is to provide a sound absorption and insulation pad and an installation method thereof.

[0007] To solve the above problems, the present invention provides the following technical solutions:

[0008] The sound absorption and insulation pad includes a backing plate. A clamping groove is provided on the head side of the backing plate, and a clamping block is provided on the tail side of the backing plate. The clamping block can be inserted into the clamping groove. After the clamping block is inserted into the clamping groove, a glue storage space is formed between the clamping block and the clamping groove. The sound absorption and insulation pad further includes:

[0009] A glue releasing member, which is provided on one of the clamping groove and the clamping block, and at least one glue releasing portion is provided on the glue releasing member;

[0010] Glue storage structure, the glue storage structure is provided on the other of the card slot and the card block, the glue storage structure includes a housing and an adhesive, and the adhesive is accommodated in the housing;

[0011] Wherein, when a glue storage space is formed between the card block and the card slot, at least part of the glue discharging portion is inserted into the housing and destroys it, so that the adhesive is filled into the glue storage space.

[0012] In the present invention, the sound absorption and sound insulation pad includes a backing plate, a card slot is provided on the first side of the backing plate, a card block is provided on the tail side of the backing plate, and when the card block is inserted into the card slot, a glue storage space is formed between the card block and the card slot; when the adhesive is stored in the glue storage space, the card block and the card slot are integrated. With such a design, it is difficult for the adhesive in the glue storage space to flow out of the glue storage space through the gap between the card block and the card slot, so as to improve the structure at the glue joint of the head and tail of the same sound absorption and sound insulation pad and improve the structure at the glue joint of different sound absorption and sound insulation pads.

[0013] In the present invention, the sound absorption and sound insulation pad further includes a glue storage structure, the glue storage structure includes a housing and an adhesive, a cavity is provided in the housing, and the adhesive is located in the cavity, that is, the adhesive is accommodated in the housing; when the adhesive is accommodated in the housing, the adhesive can be transported together with the backing plate, and the amount of the adhesive can be pre-filled in the production factory of the sound absorption and sound insulation pad. With such a design, construction personnel do not need to prepare additional adhesive on the construction site, so as to improve the structure at the glue joint of the head and tail of the same sound absorption and sound insulation pad and improve the structure at the glue joint of different sound absorption and sound insulation pads.

[0014] In addition, when the adhesive is accommodated in the housing, the amount of the adhesive can be determined by the production factory through calculation, without the need for construction personnel to determine it on the construction site according to experience or the adhesive instruction manual. With such a design, the amount of the adhesive between the card block and the card slot can be guaranteed, so as to improve the structure at the glue joint of the head and tail of the same sound absorption and sound insulation pad and improve the structure at the glue joint of different sound absorption and sound insulation pads.

[0015] In the present invention, the sound absorption and sound insulation pad further includes a glue discharging member, at least one glue discharging portion is provided on the glue discharging member, during the process of inserting the card block into the card slot, the glue discharging portion moves towards the glue storage structure to realize that the glue discharging portion destroys the housing; when the wall of the card block fits against the wall of the card slot and closes the gap therebetween, the gap between the card block and the card slot is the glue storage space, that is, a glue storage space is formed between the card block and the card slot. When a glue storage space is formed between the card block and the card slot, at least part of the glue discharging portion destroys the housing, and the adhesive flows from the damaged part of the housing into the glue storage space. With such a design, construction personnel can integrate the card block and the card slot without the help of any tools on the construction site, so as to improve the structure at the glue joint of the head and tail of the same sound absorption and sound insulation pad and improve the structure at the glue joint of different sound absorption and sound insulation pads.

[0016] It should be noted that in the present invention, the damage includes at least one of puncturing and cutting. That is to say, the glue discharging part may include a cutting edge, and the glue discharging member cuts the outer shell through the cutting edge so that the adhesive in the outer shell flows into the glue storage space; the glue discharging part may also include a puncture needle, and the glue discharging member punctures the outer shell through the puncture needle so that the adhesive in the outer shell flows into the glue storage space.

[0017] In the present invention, when the glue discharging member is arranged in the card slot, the card slot can protect the glue discharging member to reduce the probability of the glue discharging member being damaged by external objects. When the glue storage structure is arranged in the card slot, the card slot can protect the glue storage structure to reduce the probability of the glue storage structure being damaged by external objects.

[0018] Furthermore, the glue discharging member is detachably arranged in one of the card slot and the clamping block, and the glue storage structure is detachably arranged in the other of the card slot and the clamping block.

[0019] When the glue discharging member is detachably arranged in one of the card slot and the clamping block, and the glue storage structure is detachably arranged in the other of the card slot and the clamping block, the glue discharging member and the glue storage structure can be assembled to the backing plate at the construction site. With such a design, the probability of the glue discharging member and the glue storage structure being damaged by external objects during transportation is reduced, so as to further improve the structure at the head and tail bonding position of the same sound-absorbing and sound-insulating pad and improve the structure at the bonding position of different sound-absorbing and sound-insulating pads.

[0020] In addition, when the glue discharging member is detachably arranged in one of the card slot and the clamping block, and the glue storage structure is detachably arranged in the other of the card slot and the clamping block, the damaged glue discharging member and glue storage structure can be replaced separately. With such a design, the manufacturing cost of the sound-absorbing and sound-insulating pad is reduced.

[0021] Furthermore, the card slot and / or the clamping block are provided with a sliding groove, and the glue discharging member is arranged in the sliding groove and can slide along the sliding groove;

[0022] and / or, the glue discharging part includes a cutting edge for cutting the outer shell.

[0023] Furthermore, when one of the card slot and the clamping block is provided with a sliding groove, and the glue discharging part includes a cutting edge, the glue discharging member slides along the sliding groove so that the cutting edge cuts the outer shell. With such a design, the sliding groove defines the movement track of the glue discharging component to ensure that the cutting edge always corresponds to the glue storage structure; the glue discharging part is provided with a cutting edge, and the cutting edge can cut the outer shell from beginning to end to increase the speed of the adhesive in the outer shell flowing into the glue storage space.

[0024] Further, when the cushion plates are connected end to end, the volume of the glue storage space < the volume of the adhesive. With such a design, after at least part of the glue discharging part damages the outer shell and the adhesive flows from the damaged part of the outer shell into the glue storage space, the adhesive will overflow from the glue storage space, so as to facilitate the construction personnel to confirm that the adhesive is filled in place in the glue storage space.

[0025] Further, a glue supporting plate is arranged at the bottom of the clamping groove. When the cushion plates are connected end to end, the glue supporting plate closes the channel between the bottom of the glue storage space and the outside. With such a design, the glue supporting plate is used to prevent the adhesive from leaking out of the glue storage space.

[0026] Further, when the cushion plates are connected end to end, the clamping block and the clamping groove are in interference fit. After the clamping block and the clamping groove are in interference fit, the head side and the tail side of the cushion plate are connected as a whole. At this time, the adhesive can slowly solidify in the atmospheric environment. With such a design, through the interference fit between the clamping block and the clamping groove, the adhesive has sufficient time to bond the head side and the tail side of the cushion plate.

[0027] Further, two outer protrusions are arranged on the tail side of the cushion plate, the clamping block is located between the two outer protrusions, two inner protrusions are arranged on the head side of the cushion plate, and the gap between the two inner protrusions is the clamping groove. When the cushion plates are connected end to end, the outer wall of each inner protrusion is in interference fit with the inner wall of its corresponding outer protrusion, and the inner wall of each inner protrusion is in interference fit with the outer wall of the clamping block. With such a design, the connection strength between the head side and the tail side of the cushion plate is further increased after the clamping block and the clamping groove are in interference fit.

[0028] Further, the cushion plate includes a sound absorption pad and a sound insulation pad. The sound insulation pad is arranged on the outer side of the sound absorption pad. The sound insulation pad includes a fiber adhesive and a plurality of plant fiber wools, and the fiber adhesive fills the space between adjacent plant fiber wools. The sound absorption pad includes a rubber adhesive and a plurality of rubber particles, and the rubber adhesive fills the space between adjacent rubber particles.

[0029] Further, a plurality of inner convex platforms are arranged on the inner side of the sound absorption pad, and an outer convex platform is arranged on the outer side of the sound absorption pad. When the sound insulation pad is arranged on the outer side of the sound absorption pad, the sound absorption pad is connected as a whole with the sound insulation pad through the outer convex platform, so as to form a sound absorption cavity between the sound absorption pad and the sound insulation pad;

[0030] And / or, a sound absorption channel is arranged on the sound absorption pad.

[0031] In the present invention, the main functions of the inner convex platform, the outer convex platform and the sound absorption channel are all to reduce the reflected sound waves and increase the contact area between the sound waves and the cushion plate.

[0032] The installation method of the sound absorption and sound insulation pad includes the following steps:

[0033] The glue storage structure is provided at the other of the card slot and the card block;

[0034] The card block is inserted into the card slot so that the glue supporting plate closes the channel between the bottom of the glue storage space and the outside;

[0035] The glue discharging member slides along the sliding groove and cuts through the outer shell through the cutting edge so that the adhesive is filled into the glue storage space between the card block and the card slot;

[0036] The adhesive located in the glue storage space overflows the glue storage space.

[0037] In the present invention, the main purpose of the adhesive overflowing the glue storage space is to prompt the construction personnel that the adhesive between the card block and the card slot has been filled in place. Description of the Drawings

[0048] The technical solutions of the embodiments of the present invention will be explained and illustrated below with reference to the accompanying drawings of the embodiments of the present invention. However, the following embodiments are only the preferred embodiments of the present invention and not all of them. Based on the embodiments in the implementation manners, other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present invention.

[0049] In the present invention, Figures 1 to 5 is the first structural schematic diagram of the sound absorption and sound insulation pad; Figure 6 is the second structural schematic diagram of the sound absorption and sound insulation pad; Figure 7 is the third structural schematic diagram of the sound absorption and sound insulation pad; Figure 8 、 Figure 9 and Figure 10 is the fourth structural schematic diagram of the sound absorption and sound insulation pad.

[0050] Referring to Figure 1 and Figure 4 , the sound absorption and sound insulation pad includes a backing plate 1. A card slot 12 is provided on the head side of the backing plate 1, and a clamping block 11 is provided on the tail side of the backing plate 1. The clamping block 11 can be inserted into the card slot 12. Among them, the clamping block 11 can be inserted into the card slot 12 on the same backing plate 1. After the clamping block 11 on the same backing plate 1 is inserted into the card slot 12 on this backing plate 1, the head and tail of this backing plate 1 are connected end to end, so as to form a glue storage space 4 between the clamping block 11 and the card slot 12; the clamping block 11 can also be inserted into the card slot 12 on a different backing plate 1. After the clamping block 11 on one backing plate 1 is inserted into the card slot 12 on the adjacent backing plate 1, the two adjacent backing plates 1 are connected end to end, so as to form a glue storage space 4 between the clamping block 11 and the card slot 12.

[0051] In the present invention, the sound absorption and sound insulation pad further includes:

[0052] A glue discharging member 2, the glue discharging member 2 is arranged on one of the card slot 12 and the clamping block 11, and at least one glue discharging portion 21 is provided on the glue discharging member 2;

[0053] A glue storage structure 3, the glue storage structure 3 is arranged on the other of the card slot 12 and the clamping block 11, and the glue storage structure 3 includes a housing 31 and an adhesive 32, and the adhesive 32 is accommodated in the housing 11;

[0054] Among them, when a glue storage space 4 is formed between the clamping block 11 and the card slot 12, at least part of the glue discharging portion 21 is inserted into the housing 31 and destroys it, so that the adhesive 32 fills into the glue storage space 4.

[0055] Referring to Figure 2 , the glue discharging member 2 is arranged in the card slot 12, and the glue storage structure 3 is arranged on the clamping block 11. When the glue discharging member 2 is arranged in the card slot 12, only when both the glue storage structure 3 and the glue discharging member 2 are in the card slot 12 can the glue discharging member 2 destroy the glue storage structure 3. Moreover, the closer the glue storage structure 3 is to the bottom of the card slot 12, the more severely the glue discharging member 2 destroys the housing 11.

[0056] In addition, the glue - placing member 2 is arranged in the card slot 12, which can also reduce the probability that the hand of the construction worker is accidentally cut or punctured by the glue - placing part 21.

[0057] From Figure 4 It is not difficult to see that the depth of the card slot 12 > the height of the card block 11. When the depth of the card slot 12 > the height of the card block 11 and the card block 11 is inserted into the card slot 12, a glue - storage space 4 is formed between the card block 11 and the card slot 12. The glue - storage space 4 determines the amount of the adhesive 32 between the card block 11 and the card slot 12. That is to say, when the glue - storage space 4 is filled with the adhesive 32, the amount of the adhesive 32 between the card block 11 and the card slot 12 reaches the amount preset by the manufacturer, so as to ensure the connection strength at the head - to - tail adhesive joint of the same sound - absorbing and sound - insulating pad and ensure the connection strength at the adhesive joint of different sound - absorbing and sound - insulating pads.

[0058] See Figure 1 and Figure 3 As shown in

[0059] and

[0060] See Figure 2 , Figure 3 and Figure 4, the sound absorption and sound insulation pad further includes a glue - placing member 2. At least one glue - placing portion 21 is provided on the glue - placing member 2. During the process of inserting the clamping block 11 into the clamping groove 12, the glue - placing portion 21 moves towards the glue storage structure 3 to break the outer shell 31 of the glue - placing portion 21. When the outer wall 111 of the clamping block 11 fits against the inner wall 141 of the clamping groove 12 and closes the gap therebetween, the space between the clamping block 11 and the clamping groove 12 is the glue storage space 4, that is, a glue storage space 4 is formed between the clamping block 11 and the clamping groove 12. When a glue storage space 4 is formed between the clamping block 11 and the clamping groove 12, at least part of the glue - placing portion 21 breaks the outer shell 31, and the adhesive 32 flows from the damaged part of the outer shell 31 into the glue storage space 4. This structure enables construction workers to integrate the clamping block 11 and the clamping groove 12 without any tools at the construction site, so as to improve the structure at the head - to - tail bonding part of the same sound absorption and sound insulation pad and improve the structure at the bonding part of different sound absorption and sound insulation pads.

[0061] From Figure 1 It can be seen that one glue - placing portion 21 is provided on the glue - placing member 2. The glue - placing portion 21 includes a cutting edge (not marked) for cutting the outer shell 31. The glue - placing member 2 cuts the outer shell 31 through the cutting edge so that the adhesive 32 in the outer shell 31 flows into the glue storage space 4. In other embodiments of the present invention, the glue - placing member includes two or more glue - placing portions; or, one glue - placing portion is provided on the glue - placing member, and the glue - placing portion includes a puncture needle for puncturing the outer shell. The glue - placing member punctures the outer shell through the puncture needle so that the adhesive in the outer shell flows into the glue storage space; or, two or more glue - placing portions are provided on the glue - placing member, and the glue - placing portion includes a puncture needle for puncturing the outer shell. The glue - placing member punctures the outer shell through the puncture needle so that the adhesive in the outer shell flows into the glue storage space.

[0062] Of course, the glue - placing portion is not limited to the cutting edge and the puncture needle. The glue - placing portion can also be any other structure that can break the outer shell, such as a thin metal plate, a circular plastic plate, a stone chip, etc.

[0063] In the present invention, the glue - placing member 2 is detachably provided on one of the clamping groove 12 and the clamping block 11, and the glue storage structure 3 is detachably provided on the other of the clamping groove 12 and the clamping block 11.

[0064] When the glue - placing member 2 is detachably provided on one of the clamping groove 12 and the clamping block 11, and the glue storage structure 3 is detachably provided on the other of the clamping groove 12 and the clamping block 11, the glue - placing member 2 and the glue storage structure 3 can be assembled to the backing plate 1 at the construction site. When the glue - placing member 2 and the glue storage structure 3 are removed from the backing plate 1 and transported separately, the probability of being damaged by external objects during transportation will be greatly reduced.

[0065] In addition, when the glue dispensing member 2 is detachably provided on one of the card slots 12 and the clamping blocks 11, and the glue storage structure 3 is detachably provided on the other of the card slots 12 and the clamping blocks 11, even if the glue dispensing member 2 and the glue storage structure 3 are damaged, they can be replaced separately.

[0066] In the present invention, the card slot 12 and / or the clamping block 11 are provided with sliding grooves. Refer to Figure 5 , the sliding groove includes a first sliding groove 120 and a second sliding groove 110. The first sliding groove 110 is provided on the clamping block 11, and the second sliding groove 120 is provided on the card slot 12. The glue dispensing member 2 can be arranged in the first sliding groove 110 or the second sliding groove 120. When the glue dispensing member 2 is arranged in the first sliding groove 110, the glue dispensing member 2 can slide along the first sliding groove 110; when the glue dispensing member 2 is arranged in the second sliding groove 120, the glue dispensing member 2 can slide along the second sliding groove 120.

[0067] After the glue dispensing member 2 is arranged in one of the first sliding groove 110 and the second sliding groove 120, the glue storage structure 3 is arranged in the other of the first sliding groove 110 and the second sliding groove 120. This structure can reduce the manufacturing cost of the sound absorption and sound insulation pad, and moreover, when the glue dispensing member 2 and the glue storage structure 3 are installed, there is no need to determine their respective installation positions.

[0068] In the present invention, when one of the card slot 12 and the clamping block 11 is provided with a sliding groove, and the glue dispensing part 21 includes a cutting edge, the glue dispensing member 2 slides along the sliding groove so that the cutting edge cuts the outer shell 31. Specifically in this embodiment, when the card slot 12 is provided with the second sliding groove 120, and the glue dispensing part 21 includes a cutting edge, the glue dispensing member 2 slides downwards along the second sliding groove 120 so that the cutting edge cuts the outer shell 31.

[0069] In this embodiment, the first sliding groove 110 and the second sliding groove 120 are used to define the sliding tracks of the glue dispensing part 21 and the glue storage structure 3. When the same cushion plate 1 is connected end to end, at least part of the first sliding groove 110 of the cushion plate 1 corresponds to the second sliding groove 120 of this cushion plate 1; when two adjacent cushion plates 1 are connected end to end, at least part of the first sliding groove 110 of one cushion plate 1 corresponds to the second sliding groove 120 of the other cushion plate 1.

[0070] Preferably, the first sliding groove 110 is inclined. When the first sliding groove 110 is inclined and the glue storage structure 3 is arranged in the first sliding groove 110, the glue dispensing member 2 slides downwards along the second sliding groove 120 to realize different positions in the horizontal direction where the cutting edge cuts the outer shell 31. This structure changes the glue dispensing point of the damaged outer shell 31 to increase the glue dispensing speed of the outer shell 31. In other words, the glue storage structure 3 reduces the probability of generating air bubbles in the glue storage space 4 by changing the glue dispensing position and increasing the glue dispensing speed.

[0071] Preferably, when the cushion plates 1 are joined end to end, the volume of the glue storage space 4 < the volume of the adhesive 32. After at least part of the glue discharging part 21 damages the outer shell 31 and enables the adhesive 32 to flow into the glue storage space 4 from the damaged part of the outer shell 31, the adhesive 32 will overflow from the glue storage space 4 to facilitate the construction personnel to confirm that the adhesive 32 is filled in place in the glue storage space 4.

[0072] See Figure 1 and Figure 5 , a glue supporting plate 15 is provided at the bottom of the clamping groove 12. When the cushion plates 1 are joined end to end, the glue supporting plate 15 closes the channel between the bottom of the glue storage space 4 and the outside world, that is, the top surface 151 of the glue supporting plate 15, the clamping block 11 and the clamping groove 12 enclose a cavity with an opening at the top to realize that the glue supporting plate 15 closes the bottom of the glue storage space 4.

[0073] In the present invention, when the cushion plates 1 are joined end to end, the clamping block 11 and the clamping groove 12 are in interference fit. As Figure 3 and Figure 4 shown, the outer wall 111 of the clamping block 11 is in surface contact with the inner wall 141 of the clamping groove 12. After the outer wall 111 of the clamping block 11 is in surface contact with the inner wall 141 of the clamping groove 12, the head side of the cushion plate 1 and the tail side of the cushion plate 1 are connected as a whole. At this time, the adhesive 32 can slowly solidify in the atmospheric environment. That is to say, through the interference fit between the clamping block 11 and the clamping groove 12, the adhesive 32 has sufficient time to bond the head side of the cushion plate 1 and the tail side of the cushion plate 1.

[0074] In the present invention, the composition of the adhesive 32 is not improved, that is, the adhesive 32 is a conventional adhesive that can be purchased on the market. Therefore, the specific composition of the adhesive 32 is not introduced in the present invention.

[0075] See Figure 1 and Figure 2 , two outer protrusions 13 are provided on the tail side of the cushion plate 1, the clamping block 11 is located between the two outer protrusions 13, two inner protrusions 14 are provided on the head side of the cushion plate 1, and the gap between the two inner protrusions 14 is the clamping groove 12. When the cushion plates 1 are joined end to end, the outer wall 142 of each inner protrusion 14 is in interference fit with the inner wall 132 of its corresponding outer protrusion 13, and the inner wall 141 of each inner protrusion 14 is in interference fit with the outer wall 111 of the clamping block 11. This structure further increases the connection strength between the head side and the tail side of the cushion plate 1 after the interference fit between the clamping block 11 and the clamping groove 12.

[0076] At the glue joint at the head and tail of the same sound absorption and sound insulation pad (or at the glue joint between two adjacent sound absorption and sound insulation pads), sound waves need to pass through one of the outer protrusions 13, one of the inner protrusions 14, the clamping block 11, the other outer protrusion 13, and the other inner protrusion 14 in sequence. It can be seen from the above description that the outer protrusions 13 and the inner protrusions 14 effectively increase the sound insulation effect of the head side and the tail side of the cushion plate 1.

[0077] In addition, the two outer protrusions 13 and the clamping blocks 11 are in surface contact with the inner protrusion 14 respectively, so as to achieve double sealing at the head and tail adhesive joints of the same sound-absorbing and sound-insulating pad (double sealing at the adhesive joints of two adjacent sound-absorbing and sound-insulating pads). This structure can further reduce the probability of glue leakage of the adhesive 32 in the glue storage space 4 before solidification.

[0078] In the present invention, the backing plate 1 includes a sound-absorbing pad 10 and a sound-insulating pad 20. The sound-insulating pad 20 is arranged outside the sound-absorbing pad 10. The sound-insulating pad 20 includes a fiber adhesive and a plurality of plant fiber wools. The fiber adhesive fills the space between adjacent plant fiber wools. The sound-absorbing pad 10 includes a rubber adhesive and a plurality of rubber particles. The rubber adhesive fills the space between adjacent rubber particles. In other embodiments of the present invention, the backing plate includes a sound-absorbing pad and a sound-insulating pad. The sound-insulating pad is arranged outside the sound-absorbing pad. The sound-insulating pad is a sound-insulating board. The sound-absorbing pad includes a rock wool adhesive and a plurality of rock wool particles. The rock wool adhesive fills the space between adjacent rock wool particles.

[0079] The present invention does not innovate on the materials of the sound-absorbing pad 10 and the sound-insulating pad 20. Among them, the material of the sound-absorbing pad 10 can refer to the invention patent with the application number 2022100962646.

[0080] Since the sound-insulating pad 20 includes a fiber adhesive and a plurality of plant fiber wools, and the sound-absorbing pad 10 includes a rubber adhesive and a plurality of rubber particles, the material of the sound-absorbing pad 10 is different from that of the sound-insulating pad 20. When the material of the sound-absorbing pad 10 is different from that of the sound-insulating pad 20, the sound-absorbing and sound-insulating pad can at least absorb sound waves of two or more different vibration frequencies, that is, the frequency range of sound waves absorbed by the sound-absorbing and sound-insulating pad can be increased. Figure 6 and Figure 7 The structural schematic diagrams of two backing plates 1 are disclosed. It should be noted that for the convenience of marking, Figure 6 the inner boss 101 and the outer boss 102 in Figure 6 are respectively magnified, Figure 7 the sound-absorbing pad 10 and the sound-insulating pad 20 in Figure 7 are not magnified;

[0081] See Figure 6 , a plurality of inner bosses 101 are arranged on the inner side of the sound-absorbing pad 10, and an outer boss 102 is arranged on the outer side of the sound-absorbing pad 10. When the sound-insulating pad 20 is arranged outside the sound-absorbing pad 10, the sound-absorbing pad 10 is integrated with the sound-insulating pad 20 through the outer boss 102, so as to form a sound-absorbing cavity (not marked) between the sound-absorbing pad 10 and the sound-insulating pad 20.

[0082] When the sound-absorbing pad 10 is integrated with the sound-insulating pad 20 through the outer convex platform 102, sound waves need to pass through three media when passing through the sound-absorbing and sound-insulating pad. The three media are the sound-absorbing pad 10, the air in the sound-absorbing cavity, and the sound-insulating pad 20. The sound-insulating pad 20 is mainly used to block sound waves. Some sound waves will be reflected and generate reflected sound waves after encountering the obstruction of the sound-insulating pad 20. The air in the sound-absorbing cavity weakens the reflected sound waves, and the weakened reflected sound waves can be better absorbed by the sound-absorbing pad 10. The outer convex platform 102 is used to disperse the reflected sound waves to reduce the probability of resonance occurring after the sound waves converge.

[0083] In the present invention, the sound-absorbing pad 10 can increase the sound-absorbing effect of the sound-absorbing pad 10 through the volume of the inner convex platform 101 itself; the sound-absorbing pad 10 can also reduce the reflected sound waves of the sound-absorbing pad 10 through the gaps between the inner convex platforms 101.

[0084] Preferably, a plurality of arc-shaped inner sound-absorbing surfaces (not marked) are provided on the inner convex platform 101, and a plurality of arc-shaped outer sound-absorbing surfaces (not marked) are provided on the outer convex platform 102. The inner sound-absorbing surfaces and the outer sound-absorbing surfaces are used to change the reflection direction of the reflected sound waves to reduce the probability of adjacent emitted sound waves intersecting and resonating. In other embodiments of the present invention, a plurality of inner sound-absorbing planes are provided on the inner convex platform, and a plurality of outer sound-absorbing planes are provided on the outer convex platform. The function of the inner sound-absorbing plane is the same as that of the inner sound-absorbing surface, and the function of the outer sound-absorbing plane is the same as that of the outer sound-absorbing surface; or, a plurality of inner sound-absorbing planes and a plurality of inner sound-absorbing surfaces are provided on the inner convex platform, and a plurality of outer sound-absorbing planes and a plurality of outer sound-absorbing surfaces are provided on the outer convex platform.

[0085] In addition, since the inner convex platform 101 and the outer convex platform 102 are exposed outside the sound-absorbing pad 10, it is relatively easy to provide a plurality of inner sound-absorbing planes and / or a plurality of inner sound-absorbing surfaces on the inner convex platform 101, and it is relatively easy to provide a plurality of outer sound-absorbing planes and / or a plurality of outer sound-absorbing surfaces on the outer convex platform 102.

[0086] See Figure 7 , a sound-absorbing channel is provided on the sound-absorbing pad 10. The sound-absorbing channel includes an inner sound-absorbing channel 103 and an outer sound-absorbing channel 104. The inner sound-absorbing channel 103 is provided on the inner side of the sound-absorbing pad 10, and the outer sound-absorbing channel 104 is provided on the outer side of the sound-absorbing pad 10.

[0087] The functions of the inner sound-absorbing channel 103 and the outer sound-absorbing channel 104 are similar to those of the inner convex platform 101 and the outer convex platform 102. When the sound insulation pad 20 is provided outside the sound-absorbing pad 10, the sound wave needs to pass through three media when passing through the sound-absorbing and sound-insulating pad, and the three media are the sound-absorbing pad 10, the outer sound-absorbing channel 104, and the sound insulation pad 20. The sound insulation pad 20 is mainly used to block the sound wave. Some sound waves will be reflected and generate reflected sound waves after being blocked by the sound insulation pad 20. The air in the outer sound-absorbing channel 104 weakens the reflected sound waves, and the weakened reflected sound waves can be better absorbed by the sound-absorbing pad 10. The outer sound-absorbing channel 104 is used to disperse the reflected sound waves to reduce the probability of resonance when the sound waves converge.

[0088] Preferably, a plurality of arc-shaped inner sound-absorbing surfaces (not marked) are provided on the inner sound-absorbing channel 103, and a plurality of arc-shaped outer sound-absorbing surfaces (not marked) are provided on the outer sound-absorbing channel 104. The inner sound-absorbing surfaces and the outer sound-absorbing surfaces are used to change the reflection direction of the reflected sound waves to reduce the probability of intersection resonance of adjacent emitted sound waves. In other embodiments of the present invention, a plurality of inner sound-absorbing planes are provided on the inner sound-absorbing channel, and a plurality of outer sound-absorbing planes are provided on the outer sound-absorbing channel. The function of the inner sound-absorbing plane is the same as that of the inner sound-absorbing surface, and the function of the outer sound-absorbing plane is the same as that of the outer sound-absorbing surface; or, a plurality of inner sound-absorbing planes and a plurality of inner sound-absorbing surfaces are provided on the inner sound-absorbing channel, and a plurality of outer sound-absorbing planes and a plurality of outer sound-absorbing surfaces are provided on the outer sound-absorbing channel.

[0089] For the same sound-absorbing and sound-insulating pad, except for the poor sealing material itself, the most likely position for sound leakage is at the connection between the head side and the tail side of the sound-absorbing and sound-insulating pad; similarly, for two adjacent sound-absorbing and sound-insulating pads, except for the poor sealing material itself, the most likely position for sound leakage is at the connection between the two sound-absorbing and sound-insulating pads.

[0090] In the present invention, a first chamfer 15 is provided at the tail side edge of the backing plate 1, and a second chamfer 16 is provided at the head side edge of the backing plate 1. Figure 8 It can be seen that the first chamfer 15 extends to the locking block 11, and the second chamfer 16 extends to the clamping groove 12. After the head and tail of the same sound-absorbing and sound-insulating pad are connected, the first chamfer 15 and the second chamfer 16 on the backing plate 1 are spliced into a diversion groove (not marked), forming a glue storage space 4 between the locking block 11 and the clamping groove 12. And after the adhesive 32 in the glue storage space 4 overflows from the glue storage space 4, the adhesive 32 can flow along the diversion groove. After the head and tail of two adjacent sound-absorbing and sound-insulating pads are connected, the first chamfer 15 on one backing plate 1 and the second chamfer 16 on the other backing plate 1 are spliced into a diversion groove, forming a glue storage space 4 between the locking block 11 and the clamping groove 12. And after the adhesive 32 in the glue storage space 4 overflows from the glue storage space 4, the adhesive 32 can flow along the diversion groove.

[0091] In the present invention, the purposes of providing the first chamfer 15 and the second chamfer 16 on the backing plate 1 include: 1. To avoid waste of the adhesive 32 that overflows the glue storage space 4; 2. Since the first chamfer 15 and the second chamfer 16 generally do not exceed 5 mm, the adhesive 32 within the first chamfer 15 and the second chamfer 16 can solidify quickly, that is, the adhesive 32 in the diversion groove can further increase the connection strength between the clamping block 11 and the clamping groove 12; 3. When the clamping block 11 is inserted into the clamping groove 12, there may be a gap between the outer protrusion 13 and the inner protrusion 14, and the adhesive 32 in the diversion groove can seal the gap.

[0092] Preferably, a developing part (not marked) is provided on the first chamfer 15 and / or the second chamfer 16. The developing part can be a material that can change color when encountering water, and the developing part can also be a pigment coating. The presence of the developing part is used to remind the construction personnel that the sound absorption and sound insulation pad has been installed in place.

[0093] In this embodiment, the first chamfer 15 and the second chamfer 16 include at least one of a straight line segment and an arc segment, that is, the first chamfer 15 (the second chamfer 16) can be a straight chamfer, the first chamfer 15 (the second chamfer 16) can be an arc chamfer, and the first chamfer 15 (the second chamfer 16) can also be an irregularly shaped chamfer.

[0094] See Figure 9 , the first chamfer 15 includes a first recessed segment 151, a second recessed segment 152, a third recessed segment 153, and a fourth recessed segment 154 that are connected in sequence. Among them, the first recessed segment 151 is located at the edge of the clamping block 11, the second recessed segment 152 is located at the end edge of the tail side of the backing plate 1, the third recessed segment 153 is located at the edge of the outer protrusion 13, and the fourth recessed segment 154 is located at the side edge of the tail side of the backing plate 1. When the first chamfer 15 includes the first recessed segment 151, the second recessed segment 152, the third recessed segment 153, and the fourth recessed segment 154 that are connected in sequence, after the adhesive 32 located in the glue storage space 4 overflows the glue storage space 4, the adhesive 32 can flow sequentially along the first recessed segment 151, the second recessed segment 152, the third recessed segment 153, and the fourth recessed segment 154. In other embodiments of the present invention, the first chamfer may include at least one of the first recessed segment, the second recessed segment, the third recessed segment, and the fourth recessed segment.

[0095] See Figure 10, the second chamfer 16 includes a fifth recessed section 161, a sixth recessed section 162, a seventh recessed section 163, and an eighth recessed section 164 that are connected in sequence. Among them, the fifth recessed section 161 is located at the edge of the card slot 12, and the sixth recessed section 162 is located at the edge of the inner protrusion 14 (since the inner wall 141 of the inner protrusion 14 coincides with the wall of the card slot 12, in this embodiment, the edge corresponding to the inner wall 141 of the inner protrusion 14 is defined as the edge of the card slot 12). The seventh recessed section 163 is located at the end edge of the first side of the backing plate 1, and the eighth recessed section 164 is located at the side edge of the first side of the backing plate 1. When the second chamfer 16 includes the fifth recessed section 161, the sixth recessed section 162, the seventh recessed section 163, and the eighth recessed section 164 that are connected in sequence, after the adhesive 32 located in the glue storage space 4 overflows from the glue storage space 4, the adhesive 32 can flow sequentially along the fifth recessed section 161, the sixth recessed section 162, the seventh recessed section 163, and the eighth recessed section 164. In other embodiments of the present invention, the second chamfer may include at least one of the fifth recessed section, the sixth recessed section, the seventh recessed section, and the eighth recessed section.
