Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to a sound insulation structure at the connection between a wall body and a wire box with integrated pipelines of a double-layer ALC wallboard. Background Technique

[0002] In buildings, especially prefabricated buildings, autoclaved aerated concrete slabs are widely used for partition walls. Autoclaved aerated concrete slabs are made of siliceous and calcareous materials as the main raw materials, adding foaming agents, and using a steel mesh sheet with rust prevention technical treatment as the reinforcement. They are made into lightweight concrete slabs with a porous structure through processes such as casting, forming, cutting, and autoclaved curing. They are abbreviated as AAC boards or ALC boards, and are often called autoclaved aerated concrete strip boards.

[0003] Since wires need to be routed and wire boxes need to be installed on the wall body after installation, it is usually necessary to open wire pipe grooves or holes on the wall body. Opening wire pipe grooves or holes requires using a grooving machine or a percussion drill to chisel the wall body. This process often causes cracks in the joints between the wall body and the main structure and the joints between the boards; the parts filled with mortar after the installation of the wire pipes will also crack due to the inconsistent materials between the mortar and the wall body; moreover, the dust, noise, sewage, and construction waste generated during the grooving, chiseling, backfilling, and plugging processes greatly affect the construction environment. In response to this diversified demand in the construction market, domestic autoclaved aerated concrete board production enterprises have also carried out research and development. During the production process, pipelines are pre-buried in autoclaved aerated concrete boards. Mainly according to the requirements of the construction site, the layout drawing of autoclaved aerated concrete boards is designed. According to the positions of the water and electricity wire pipe points in the layout drawing, the method of pre-burying wire pipes and wire boxes during the production process is used to fix the wire pipes and wire boxes on the steel mesh sheet. After steam curing, the concrete layer on the surface of the wire box at one end of the wire pipe is removed, and the concrete layer at the other end of the wire pipe is removed to form a groove, install the corresponding quick-install joints or expose the wire pipes, form an integrated pipeline board and mark it. At the construction site, the autoclaved aerated concrete boards marked correspondingly are installed according to the layout drawing to form an integrated pipeline autoclaved aerated concrete board wall body.

[0004] For example, the Chinese patent with the application number "202320818558.5" discloses an ALC wallboard with a wire box that does not require grooving, which pre-sets a wire box on the wallboard in advance. However, whether it is set later or in advance, it will also cause the sound insulation effect of the original wallboard to become worse. In the existing construction methods, generally two ALC wallboards are set, and the wire pipes pass through the air layer formed between the two ALC wallboards. After setting the wire box on the ALC wallboard, the wall thickness of the wire box part will become thinner, and the sound is easily transmitted to the air layer between the two, and then transmitted to the other side. If wire boxes are set on both ALC wallboards, the sound insulation effect will be even worse, affecting the user experience.

[0005] The present utility model is studied and proposed in view of the deficiencies of the prior art. Summary of the Invention

[0006] To solve the above technical problems, the present utility model provides a sound insulation structure at the connection between a wall and a junction box for an integrated pipeline in a double-layer ALC wall panel, effectively solving the problem of poor sound insulation caused by installing a junction box through an installation hole in an ALC wall in the prior art.

[0007] A sound insulation structure at the connection between a wall and a junction box for an integrated pipeline in a double-layer ALC wall panel of the present utility model includes an integrated pipeline wall unit of an ALC wall panel. The integrated pipeline wall unit of the ALC wall panel includes two spaced ALC wall panels. There is an air interlayer between the ALC wall panels.

A pipeline is provided in the air interlayer and is connected to the junction box. A first fixing portion for covering and fixing the side and rear portions of the junction box to form an integral body is provided in the installation hole on one side of the ALC wall panel. A second fixing portion for filling the side portion of the junction box is provided in the installation hole on the other side of the ALC wall panel. A sound insulation layer is correspondingly provided in the installation hole at the rear portion of the junction box.

[0008] For the sound insulation structure at the connection between a wall and a junction box for an integrated pipeline in a double-layer ALC wall panel as described above, the rear end of the first fixing portion protrudes from the inner side of the ALC wall panel and extends towards the peripheral side of the ALC wall panel to form a covering layer.

[0009] For the sound insulation structure at the connection between a wall and a junction box for an integrated pipeline in a double-layer ALC wall panel as described above, the sound insulation layer is filled and abuts against the inner side of the opposite ALC wall panel.

[0010] For the sound insulation structure at the connection between a wall and a junction box for an integrated pipeline in a double-layer ALC wall panel as described above, the sound insulation layer is formed by one or more of rock wool, glass wool, and rubber sheets.

[0011] For the sound insulation structure at the connection between a wall and a junction box for an integrated pipeline in a double-layer ALC wall panel as described above, the materials of the first fixing portion and the second fixing portion are polymer cement mortar or ordinary cement mortar.

[0012] For the sound insulation structure at the connection between a wall and a junction box for an integrated pipeline in a double-layer ALC wall panel as described above, the junction boxes in the two ALC wall panels are arranged symmetrically or staggeredly.

[0013] For the sound insulation structure at the connection between a wall and a junction box for an integrated pipeline in a double-layer ALC wall panel as described above, the pipeline located in the air interlayer is connected to the junction box through a PVC corrugated hose.

[0014] The present utility model also provides a construction method for the sound insulation structure at the connection between the wall body and the junction box of the double-layer ALC wall panel with integrated pipeline. Using the sound insulation structure at the connection between the wall body and the junction box of the double-layer ALC wall panel with integrated pipeline as described above, it includes the following steps:

[0015] S1. Install the ALC wall panel on one side of the ALC wall panel unit with integrated pipeline, and open an installation hole for installing the junction box at the corresponding position of the ALC wall panel;

[0016] S2. Install the pipeline on the inner side of the installed ALC wall panel;

[0017] S3. Install the junction box in the installation hole obtained in step S1, and then insert one end of the corresponding pipeline into the junction box for connection;

[0018] S4. Fill the peripheral gap and the rear part of the junction box with polymer cement mortar to form a first fixing part;

[0019] S5. Install the ALC wall panel on the other side, an air layer is formed between the two ALC wall panels, and the corresponding installation hole is opened on the ALC wall panel to install the junction box. The junction box can be symmetrically or staggeredly arranged with the junction box in step S3;

[0020] S6. Set a sound insulation layer at the rear part of the junction box in step S5. The pipeline penetrates through the sound insulation layer, and the sound insulation layer is composed of one or more of rock wool, glass wool or rubber sheet;

[0021] S7. Install the junction box for the installation hole obtained in step S5, and the rear part of the junction box is correspondingly connected to the corresponding pipeline pre-buried in the air layer;

[0023] For the above construction method of the sound insulation structure at the connection between the wall body and the junction box of the double-layer ALC wall panel with integrated pipeline, the installation hole in step S5 has a structure that gradually increases from the outside to the inside.

[0024] Compared with the prior art, the present utility model has the following beneficial effects:

[0025] 1. The setting of the first fixing part and the second fixing part can relatively fix the junction box in the installation hole, and can fill the gap between the junction box and the installation hole, making the junction box more firmly fixed, and at the same time can achieve a better sound insulation effect.

[0026] 2. The setting of the sound insulation layer can achieve an effective sound insulation effect, preventing the sound from being easily transmitted through the junction box and the installation hole to the air interlayer and then further transmitted due to the installation holes being opened in the ALC wall panel for installing the junction box. After the sound insulation layer is arranged at the rear of the second fixing part, and on the side of the first fixing part near the air interlayer at the rear of one of the junction boxes, a covering layer is integrally formed. The first fixing part, the second fixing part, and the covering layer are all made of polymer cement mortar. Therefore, the first fixing part, the second fixing part, the covering layer, the air interlayer, and the sound insulation layer together form a multi-layer composite sound insulation structure, thus making up for the defect of poor sound insulation effect caused by opening installation holes in the ALC wall panel for installing the junction box in the prior art. Therefore, the utility model can effectively block the further transmission of sound and has a good sound insulation effect.

[0027] 3. The junction box and the wire pipe can be fixed correspondingly through the first fixing part, the second fixing part, and the sound insulation layer.

[0028] 4. In addition, the sound insulation layer fills and abuts against the inner side of the opposite ALC wall panel. Especially when the two junction boxes are symmetrically arranged, the wire pipe in the air interlayer is further covered. The sound insulation layer with better sound insulation effect fills the corresponding part of the air interlayer, which will further improve the sound insulation effect and play a role in saving materials.

[0029] 5. The method of the utility model can quickly fix the junction box, improve the construction efficiency. At the same time, relying on the structure of the utility model, after the junction box is installed on the ALC wall panel, an integrated wall structure can be formed, and it can have excellent sound insulation effect, effectively preventing the problem of poor sound insulation effect caused by opening installation holes for installing the junction box.

Detailed implementation mode

[0037] The following will describe in detail the implementation mode of the present utility model with reference to the accompanying drawings.

[0038] Please refer to Figures 1 to 6 , a sound insulation structure at the connection between a wall body and a junction box of a double-layer integrated ALC wallboard and pipeline of the present utility model includes an integrated wall unit 100 of an ALC wallboard and pipeline. The integrated wall unit 100 of an ALC wallboard and pipeline includes two spaced ALC wallboards 1. An air layer 2 is formed between the ALC wallboards 1. Mounting holes 3 penetrating through to the air layer 2 are formed at corresponding positions of the two ALC wallboards 1. A junction box 4 is arranged in the mounting holes 3. The junction boxes 4 can be arranged symmetrically or staggeredly. Pipelines 5 correspondingly connected to the junction box 4 are arranged in the air layer 2. It should be noted that the pipelines 5 located in the air layer 2 can be set in a direction according to requirements. And the pipelines 5 in the air layer 2 and the junction box 4 can be connected through a PVC corrugated hose. When the end of the pipeline 5 is connected to the junction box 4, it usually requires a certain bending or connecting a corresponding elbow. When the former is bent, it is easy to cause the deformation and flattening of the bent part of the pipeline 5, thus affecting wire threading and wire replacement; if the latter connection method is adopted, it will increase the on-site construction efficiency and cost. And the PVC corrugated hose is convenient for bending. Therefore, connecting the pipeline 5 and the junction box 4 through the PVC corrugated hose can not only be convenient for connecting with the junction box 4 to adapt to bending at various angles, facilitate subsequent wire threading and wire replacement, but also be convenient for workers to construct.

[0039] A first fixing part 6 for covering and fixing the side and rear of the junction box 4 is arranged in the mounting hole 3 of one of the ALC wallboards 1. The material of the first fixing part 6 is polymer cement mortar or ordinary cement mortar.

[0040] It should be noted that the present utility model preferably uses polymer cement mortar. Polymer cement mortar is prepared by mixing cement, aggregate (fine sand) and an organic polymer that can be dispersed in water. The polymer can be a homopolymer polymerized from a single monomer or a copolymer polymerized from two or more monomers. The polymer must form a film to cover the aggregate under corresponding environmental conditions, and make the cement body and the aggregate form a strong bond. And the polymer in the polymer cement mortar forms a corresponding network structure to effectively prevent the occurrence of microcracks and the expansion of cracks.

[0041] Therefore, through the polymer cement mortar, the junction box 4 can be stably fixed in the installation hole 3, and the tiny gap between the junction box 4 and the installation hole 3 can be filled, making the fixation of the junction box 4 more stable. At the same time, it can achieve a better sound insulation effect.

[0042] In the installation hole 3 on the ALC wallboard 1 on the other side, a second fixing part 60 for filling the side part of the junction box 4 is provided. A sound insulation layer 7 is arranged at the rear of the junction box 4. The sound insulation layer 7 is one or more of rock wool, glass wool, and rubber sheet 10. In addition, fireproof cotton can be filled in the sound insulation layer 7 to improve the fireproof performance. The material of the second fixing part 60 is polymer cement mortar or ordinary cement mortar, and preferably polymer cement mortar.

[0043] In this embodiment, by arranging the sound insulation layer 7 at the rear of the second fixing part 60, the sound insulation effect can be effectively achieved, preventing the phenomenon that the sound is transmitted to the air separation layer 2 and then further transmitted. After arranging the sound insulation layer 7 at the rear of the second fixing part 60, the sound transmission to the air separation layer 2 can be effectively blocked, making up for the defect of poor sound insulation effect caused by opening the installation hole 3 to install the junction box 4.

[0044] As can be seen from the above, the first fixing part 6, the second fixing part 60, the sound insulation layer 7, and the air separation layer 2 form the multi-layer composite sound insulation structure of the present utility model, effectively improving the sound insulation effect.

[0045] As a preferred solution of this embodiment, the rear end of the first fixing part 6 protrudes from the inner side of the ALC wallboard 1 and extends to the peripheral side of the ALC wallboard 1 to form a coating layer 8 with a certain thickness. By protruding the rear end of the first fixing part 6 and extending it to the peripheral side of the ALC wallboard 1 to form the coating layer 8, the connection stability can be further improved. The coating layer 8 can effectively block the sound, further improving the sound insulation effect.

[0046] The coating layer 8 and the first fixing part 6 are integrally formed, and preferably polymer mortar as well. The total thickness of the first fixing part 6 and the coating layer 8 at the rear of the junction box 4 on the ALC wallboard 1 is more than 30 mm. Since the material mass density of the first fixing part 6 and the coating layer 8 is different from that of the ALC wallboard 1, that is, the mass density of the polymer cement mortar is much higher than that of the ALC wallboard 1. The density of the polymer cement mortar is generally 1600 kg / m 3 Above, the density of the ALC wallboard 1 is generally 650 kg / m 3 Below, it can be seen that the mass density of the coating layer 8 is much greater than that of the ALC wallboard 1; according to the air sound insulation mass law of a single-layer homogeneous wall, the sound insulation amount of a wall or other building board is proportional to the logarithm of its apparent density (or mass per unit area), which can be expressed by the formula:

[0047] R = 20lgm + 20lgf - 48

[0048] Where: R is the sound insulation quantity, and the unit of the sound insulation quantity is dB; m is the surface density, and the unit of the surface density is kg / m 2 ; f is the incident sound wave frequency, and the unit of the incident sound wave frequency is Hz.

[0049] In the wall unit of the conventional 200 - mm - thick double - layer ALC wall panel 1, the thickness of each ALC wall panel 1 is 75 mm, and the air layer 2 formed between the two ALC wall panels 1 is 50 mm. Therefore, the polymer cement mortar with a thickness of 30 mm can achieve the sound insulation effect of the ALC wall panel 1 with a thickness of 75 mm.

[0050] As a further solution of this embodiment, the sound insulation layer 7 is filled with rock wool and / or glass wool and abuts against the inner side of the opposite ALC wall panel 1, and the air layer 2 at this part is filled up, thus further improving the sound insulation effect. The filled sound insulation layer 7 can abut against the inner side wall of the other ALC wall panel 1, effectively preventing the sound insulation layer 7 from loosening and falling off, and ensuring the stable and reliable sound insulation effect. In addition, when the two junction boxes 4 are symmetrically arranged, the sound insulation layer 7 at this place is located between the two junction boxes 4, so that a sound insulation layer 7 can be shared between the two junction boxes 4, ensuring good sound insulation effect while saving materials.

[0051] As a further solution of this embodiment, the sound insulation layer 7 can use one or two of rock wool and glass wool, and is adhesively bonded to the polymer cement mortar accordingly. Therefore, the sound insulation layer 7 can be stably fixed at the corresponding position through the polymer cement mortar.

[0052] In addition, when using the rubber sheet 10 for sound insulation, there are the following two situations:

[0053] One. As Figure 2 shown, the rubber sheet 10 is snap - connected to the rear of the corresponding junction box 4, and the part corresponding to the air layer is filled with rock wool or glass wool and abuts against the inner side wall of the other ALC wall panel 1.

[0054] Two. As Figure 5 shown, only a single rubber sheet 10 is used for sound insulation. The rubber sheet 10 is snap - connected and attached to the rear of the corresponding junction box 4, and the wire pipe 5 also penetrates through the rubber sheet 10 accordingly.

[0055] By using the above - mentioned structure, the present utility model also provides a construction method for the sound insulation structure at the connection of the wall and the junction box of the double - layer ALC wall panel with integrated pipeline, including the following steps;

[0056] S1. Install the ALC wall panel 1 on one side of the integrated wall unit 100 for ALC wall panels and pipelines. Drill an installation hole 3 for installing the junction box 4 in this ALC wall panel 1. By drilling the non-precast installation hole 3 subsequently, it provides better and more convenient operation space for installers, avoiding the problem of large deviation between the precast installation hole 3 and the actual situation.

[0057] S2. Install the pipeline 5 on the inner side of the installed ALC wall panel 1. This side will form an air layer 2 corresponding to the inner side of another ALC wall panel 1 in the subsequent steps. It should be noted that in this step, a part of the pipeline 5 is reserved in the installation hole 3, and the rest is arranged according to the actual situation. The pipeline 5 can be arranged in the required direction.

[0058] S3. Install the junction box 4 in the installation hole 3 obtained in step S1. Then connect one end of the corresponding pipeline 5 to this junction box 4. According to actual needs, the junction box 4 can be firmly connected to the ALC wall panel 1 with bolts or nails.

[0059] S4. Fill the peripheral voids and the rear part of the junction box 4 with polymer cement mortar to form the first fixing part 6. By filling the polymer cement mortar, the junction box 4 is fixed to the ALC wall panel 1. This filled part is connected to the ALC wall panel 1 as a whole, enhancing the sound insulation effect and the stability of the connection. At the same time, it can also support the junction box 4. It should be noted that the first fixing part 6 has two parts. When filling, first fill the voids between the junction box 4 and the periphery of the installation hole 3. Since this is the installation of the first ALC wall panel 1, there will be no other objects interfering or blocking on the inner side of this ALC wall panel 1. After filling the peripheral voids of the junction box 4, immediately continue to fill the polymer cement mortar on the inner side of the ALC wall panel 1 at the rear end of the junction box 4 to form a coating layer 8, which fully separates the junction box 4 from the subsequently formed air layer 2.

[0060] S5. Install the other ALC wall panel 1. An air layer 2 is formed between the two ALC wall panels 1. This ALC wall panel 1 correspondingly drills an installation hole 3 for installing the junction box 4. The junction box 4 can be symmetrically or staggeredly arranged with the junction box 4 in step S3.

[0061] S6. A sound insulation layer 7 is provided at the rear of the wire box 4 in step S5. The wire conduit 5 passes through the sound insulation layer 7. The sound insulation layer 7 is composed of one or more of rock wool, glass wool or rubber sheet 10. It should be noted that the sound insulation layer 7 can also be composed of other materials with sound insulation or sound absorption effects. In this step, when the wire conduit 5 passes through the sound insulation layer 7, a guiding component can be provided at the front end of the wire conduit 5 to facilitate its passing through the sound insulation layer 7. The guiding component is removably connected to the corresponding end of the wire conduit 5. When passing through the sound insulation layer 7, the resistance can be reduced, and it can also prevent the materials in the sound insulation layer 7 from being poked and scattered, thus damaging the sound insulation effect. In addition, the two wire conduits 5 are arranged in a staggered manner, which can prevent them from interfering with each other and make the structure more compact. Also, sound insulation materials can be filled while laying the wire conduits 5 to form the sound insulation layer 7, so that the sound insulation materials will not be scattered.

[0062] S7. Install the wire box 4 in the installation hole 3 obtained in step S5, and the rear part of the wire box 4 is correspondingly connected to the corresponding wire conduit 5 that has been inserted and pre-buried in the air separation layer 2.

[0063] S8. Fill the gap between the wire box 4 and the periphery of the installation hole 3 in step S7 with polymer cement mortar to form the second fixing part 60, and make the polymer cement mortar adhere to the sound insulation layer 7 to complete the installation of the wire box 4 on this side. According to actual needs, the wire box 4 can be strengthenedly connected to the ALC wallboard 1 with bolts or nails.

[0064] Through the above steps of construction, the wire box 4 can be quickly fixed, improving the construction efficiency. At the same time, relying on the structure of the present utility model, after installing the wire box 4 on the ALC wallboard 1, it can also have excellent sound insulation effect, avoiding the problem of poor sound insulation effect caused by opening the installation hole 3 to install the wire box 4. At the same time, after constructing by the method of the present utility model, a multi-layer composite sound insulation structure formed by the first fixing part 6, the second fixing part 60, the sound insulation layer 7 and the air separation layer 2 can be obtained, thus effectively improving the sound insulation effect.

[0065] In the above corresponding steps, in order to facilitate the better connection between the wire conduit 5 and the wire box 4, the wire conduit 5 located in the air separation layer 2 can be connected to the wire box 4 through a PVC corrugated hose.

[0066] Consult Figure 4 , in step S5 of this construction method, the installation hole 3 opened on the ALC wallboard 1 has a structure that gradually increases from the outside to the inside. With this structural setting, more sound insulation materials can be filled between the installation hole 3 and the corresponding wire box 4 to achieve a better sound insulation effect.
