Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, specifically a double-cavity sound-insulating vertical keel with built-in fasteners. Background Technology

[0002] In the field of building decoration and sound insulation engineering, light steel keel, as the core load-bearing and supporting component of wall structure, is widely used in the construction of partition walls in various scenarios such as residential buildings, commercial buildings, and public facilities due to its advantages of convenient installation, high construction efficiency, and high degree of industrialization. With the continuous improvement of people's requirements for building sound insulation performance, construction flexibility, and cost control, double-cavity sound-insulating vertical keel has gradually become the mainstream choice in sound insulation wall systems because it can weaken sound wave transmission and improve sound insulation effect through the cavity structure. Currently, traditional prefabricated lightweight partition walls on the market often use C-shaped top and bottom keels, vertical keels, through-core horizontal keels, and gypsum board and rock wool to form the wall. However, the sound insulation effect of this combination is limited and cannot meet the privacy requirements of environments such as residences and offices. Therefore, prefabricated wall structures with built-in sound insulation panels have emerged on the market.

[0003] The installation and fixing of sound insulation panels in prefabricated partition walls has always been a challenge. Adding new fixing structures would complicate the vertical keel structure and increase material usage. In existing technologies, the installation and fixing of sound insulation panels mostly rely on the natural grooves on both sides of the H-shaped structure at the keel connection. To save steel consumption in the vertical keel and improve the speed of prefabricated construction, application number CN202022435948.3 (Background Art 1) discloses a vertical keel for prefabricated high sound insulation walls, including a base plate and side plates on both sides of the base plate, with one or more through holes on the base plate; the key feature is the presence of an inwardly recessed "U"-shaped groove on the base plate, with a positioning abutment edge on the bottom edge of the "U"-shaped groove. The installation steps for this technical solution in ordinary (within 3 meters) non-ultra-high space walls are as follows: Step 1: Install the floor joists on the ground and the ceiling joists on the interior ceiling; Step 2: Install all vertical keels between the ground keel and the top keel according to the spacing requirements in the drawing, and fix them with vertical locking nails; Step 3: Insert one side of the sound insulation board into the "U" shaped slot of the vertical keel, and fix the other side against the positioning abutment edge of the adjacent vertical keel by nailing or gluing. Step 4: Repeat steps 1 to 3 to continue the installation of the sound insulation panels. In this technical solution, the sound insulation panels do not need to be simultaneously inserted and positioned on both sides, nor do they require horizontal joists for positioning. This significantly improves installation efficiency, reduces material and labor costs, greatly enhances wall strength and sound insulation performance, completely solves the problem of sound leakage, and achieves fast, efficient, and streamlined on-site assembly.

[0004] However, when using lockstitch connections, the sound insulation board only has 20-25 mm of clearance against the edge and is blocked by the outer vertical edge of the keel, making it impossible to nail directly; only angled work is possible. Lockstitching can damage the edges of the sound insulation board, making it prone to falling off and affecting structural safety. It also fails to solve the sound transmission problem, thus failing to achieve a high sound insulation effect. Furthermore, once the sound insulation board is fixed with lockstitches, it cannot be reused, and disassembly will generate a large amount of construction waste. On the other hand, when using adhesive fixing, firstly, the vertical keel surface has oil stains from processing, and removing these stains is very tedious and damages the galvanized layer on the keel surface; secondly, the positioning of the vertical keel against the edge and the sound insulation... The small contact area of ​​the board, coupled with insufficient flatness of the sound insulation board edges, results in insufficient adhesion. Thirdly, on-site adhesive application is easily affected by the environment and climate, leading to unevenness or deformation of the sound insulation board and vertical keel surfaces. After bonding, the positioning of the sound insulation board and the vertical keel, the pressure applied to the edge, and the drying time are all challenges. The keel is suspended vertically, making construction very complicated and requiring a professional construction team, which increases the difficulty of construction management. Fourthly, adhesive bonding requires a curing period, and collisions are strictly prohibited during the curing period. This is difficult to control on-site, resulting in the inability to carry out cross-operations of wall pipes and decorations. The next process can only be carried out after the adhesive has dried and cured, which reduces the overall construction efficiency.

[0005] Therefore, using nails or adhesives at the junction of the sound insulation board and the support edge presents significant problems and is not very practical. Moreover, if the sound insulation board is nearly 3 meters high, the flatness is even worse, the deformation is greater, and the installation of the sound insulation board is more difficult. At least two workers are needed to install the sound insulation board at the same time. This is only for walls within 3 meters. If the installation is on a super high wall of more than 3 meters, the difficulty is even greater and the structural risks are even greater.

[0006] Patent application number 202123128117.2 (Background Art 2) discloses a prefabricated wall quick-installation keel structure. The vertical keel with its own misaligned clamps is formed by stamping and flipping the two sides of the U-shaped slot, which achieves the effect of quickly and efficiently fixing the sound insulation board and improving the installation efficiency of the sound insulation board while saving the amount of materials. However, because the through holes on both sides will produce gaps when installing the sound insulation board, the sound insulation effect will be reduced (the through holes on both sides form through grooves, and the sound leaks through the through grooves). In addition, the thickness deviation of the sound insulation board is large, and it is difficult to adapt to the problem of sound insulation boards of different thicknesses on site. Therefore, we propose a double cavity sound insulation vertical keel with its own clamps. Utility Model Content

[0007] The purpose of this utility model is to provide a double-cavity sound insulation vertical keel with built-in fasteners to solve the technical problems mentioned in the background art 1, which is that the sound insulation board cannot be reused and the installation efficiency is low due to the use of locking nails or adhesive to fix the sound insulation board, and the technical problems mentioned in the background art 2, which are that the sound insulation effect is reduced due to gaps generated when installing the sound insulation board.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a double-cavity sound-insulating vertical keel with built-in locking mechanism, comprising multiple sets of vertical keel bodies, two sets of sound-insulating panels disposed between two sets of vertical keel bodies, multiple sets of adjustable levers and strips respectively disposed on one side of each vertical keel body, the multiple sets of adjustable levers and strips forming a locking groove, and slots provided on the vertical keel body; The adjustable lever has a T-shaped structure, and three sides of the adjustable lever have an arc-shaped structure.

[0009] Preferably, the top of the vertical keel body is provided with a tianlong bone, and the top of the vertical keel body penetrates into the interior of the tianlong bone.

[0010] Preferably, both sides of the vertical keel body are bent to form folded edges.

[0011] Preferably, the vertical keel body has two sets of placement grooves formed by bending.

[0012] Preferably, multiple sets of threading holes are evenly distributed on the side of the vertical keel body and along the length of the vertical keel body.

[0013] Preferably, the interior of the vertical keel body is provided with multiple sets of punched grooves.

[0014] Compared with the prior art, the beneficial effects of this utility model are: (1) By setting an adjustable lever on one side, the width of the slot can be adjusted by bending the lever, which can be adapted to sound insulation boards of different thicknesses. This solves the problem that the traditional slot is not adjustable and cannot adapt to the installation of sound insulation boards of different thicknesses. The sound insulation board is inserted into the slot and the slot without the need for nails or adhesives, avoiding the damage to the sound insulation board caused by the traditional use of nails for fixing, reducing costs. In addition, since the adjustable lever is set on one side, the problem of gaps being generated when installing the sound insulation board due to the through holes on both sides is solved, which leads to a reduction in the sound insulation effect.

[0015] (2) Two sets of sound insulation boards, together with rock wool or glass wool filled in the double cavity, play a double role in blocking sound waves, improving the sound insulation performance of the wall, and meeting the privacy needs of living rooms and offices.

[0016] (3) Through multiple wire holes, it is convenient for water and electricity pipelines to pass through, and the stamping waste can be recycled and reused, reducing the cost of raw materials. At the same time, it can also reduce the weight of the finished product, making it easier to transport and construct, and improving the cost performance. Attached Figure Description

Detailed Implementation

[0018] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Example 1 Please see Figures 1-7This utility model provides a technical solution: a double-cavity sound-insulating vertical keel with a built-in locking mechanism (viewed from left to right, the first set of sound-insulating panels 104 are installed between the slots 108 on the first set of vertical keel bodies 100 and the slots 108 on the second set of sound-insulating panels 104; the second set of sound-insulating panels 104 are installed in the slots 109 on the right side of the second set of vertical keel bodies 100 and the slots 108 in the third set of vertical keel bodies 100), the locking mechanism being an adjustable lever 103, which is adjustable... The sheet 103 uses a forward punching and reverse deflection process, saving raw materials and reducing the weight of the finished product. The adjustable deflector 103 can be bent to accommodate sound insulation panels 104 of different thicknesses (the width of the slot 108 varies when the adjustable deflector 103 is bent, adapting to different thicknesses of sound insulation panels 104), improving its applicability. The vertical keel body 100 is made of metal and must be used with the top and bottom keels (the top and bottom keels consist of the top keel 102 and the bottom keel 104). The keel structure consists of a ground keel located at the bottom of the vertical keel body 100 (not shown in the figure, with the same structure as the top keel 102) and sound insulation panels 104. It includes multiple sets of vertical keel bodies 100, with two sets of sound insulation panels 104 positioned between each set of vertical keel bodies 100. Each side of the vertical keel body 100 is equipped with multiple sets of adjustable levers 103 and strips 105. The strips 105 and the vertical keel bodies 100 have an overlapping structure. A slot 108 is formed between them, and a slot 109 is provided on the vertical keel body 100. The sound insulation plate 104 can be inserted into the slot 108 and the slot 109. Under normal use, the sound insulation plate 104 can act as a baffle to achieve part of the sound insulation effect. When it is necessary to install other sound insulation plates 104 of different thicknesses, the sound insulation plate 104 can be manually removed (by bending the adjustable lever 103 toward the punched groove 110), and then any thickness of sound insulation plate 104 can be installed. The adjustable lever 103 adopts a forward punching and reverse shifting process. In its initial state, it is located inside the punching groove 110, forming a slot 108 with the strip 105 with a basic width. After the sound insulation panel 104 is inserted into the slot 108 and the slot 109, the width of the slot 108 can be changed by manually bending the adjustable lever 103 (bending it away from the punching groove 110). The larger the bending angle, the smaller the width of the slot 108, and vice versa. This is to accommodate sound insulation panels 104 of different thicknesses, achieving a fixation without nails or adhesives, and avoiding the problem of damage to the sound insulation panel 104 caused by traditional fixing methods. The adjustable lever 103 has a T-shaped structure or other structures, and the three sides of the adjustable lever 103 have an arc-shaped structure. The arc-shaped structure can reduce the use of materials and reduce costs. The adjustable lever 103 is manually adjusted on site and can be adjusted to any angle to adapt to sound insulation panels 104 of different thicknesses.

[0020] Example 2 Please refer to Example 1. Figures 1-7 The top of the vertical keel body 100 is provided with a top keel 102. The top of the vertical keel body 100 is inserted into the interior of the top keel 102. The width of the vertical keel body 100 is slightly narrower than the width of the top keel 102 and the bottom keel. The top keel 102, the bottom keel and the two ends of the vertical keel body 100 are all fixed with screws. The two ends of the top keel 102, the bottom keel and the vertical keel body 100 are all provided with screw slots for screws to pass through, which increases the firmness of the connection between them. Both sides of the vertical keel body 100 are bent to form folded edges. When the rock wool or glass wool is placed in the placement groove 106, the folded edges can increase the clamping effect on the rock wool or glass wool, thereby increasing the stability after the rock wool or glass wool is filled. The vertical keel body 100 has two sets of placement grooves 106 formed by bending. The two sets of placement grooves 106 are two sets of cavities, forming a double cavity effect. When the placement grooves 106 are filled with rock wool or glass wool, the porous structure of the two materials can absorb and reflect the sound waves passing through the placement grooves 106. After the sound waves enter the placement grooves 106, the fiber gaps of the rock wool and glass wool will hinder the propagation of the sound waves. Some of the sound waves are reflected multiple times in the gaps and their energy is consumed, thereby reducing the penetration ability of the sound waves. Compared with the unfilled placement grooves 106, the sound insulation performance of the wall can be significantly improved. At the same time, rock wool and glass wool have good thermal insulation performance. After filling, the heat transfer of the wall can be reduced, improving the energy-saving effect of the building.

[0021] Example 3 Please refer to Example 2. Figures 1-7 Multiple sets of wire holes 101 are evenly distributed on the side of the vertical keel body 100 and along the length of the vertical keel body 100. The interior of the vertical keel body 100 also has multiple sets of punched slots 110. The punched slots 110 are used to allow horizontal water and electricity pipes to pass through after the wall is assembled, avoiding the need to drill additional holes in the wall later and damaging the structure, thus ensuring the integrity of the wall. The multiple sets of punched slots 110 not only facilitate the passage of water and electricity pipes, but also save materials. The original metal material (i.e., circular scrap) formed after punching can be used for the production of subsequent raw materials such as the vertical keel body 100, saving costs.

[0022] Working principle and usage process of this utility model: When using this utility model, first lay out the lines on site, fix the top keel 102 and the bottom keel, and fix the top keel 102 and the bottom keel to the light steel structure (beam and plate) using expansion screws or self-tapping screws. Then (viewed from left to right), the first and second vertical keel bodies 100 are placed inside the top keel 102 and the bottom keel. Next, a sound insulation plate 104 is inserted between the first and second vertical keel bodies 100. Then, the third vertical keel body 100 is placed inside the top keel 102 and the bottom keel, and a sound insulation plate 104 is inserted between the second and third vertical keel bodies 100. At this point, all the sound insulation plates 104 are inserted into the slots 108 and 109 in the vertical keel bodies 100. Screws are used to fix the contact points between the top keel 102, the bottom keel, and the vertical keel bodies 100, so that the top keel 102, the bottom keel, and the vertical keel bodies are properly secured. The two ends of 100 are fixed together. At this time, the back of the sound insulation board 104 is in contact with the front of the strip 105. Then, the adjustable lever 103 in the perforated groove 110 is pulled outward (bent and bent) to an angle close to 180 degrees. At this time, the adjustable lever 103 is in contact with the front of the sound insulation board 104. If the thickness of the sound insulation board 104 is different, it is only necessary to bend the adjustable lever 103 outward at different angles to contact the front of the sound insulation board 104. The wire hole 101 on the side of the vertical keel body 100 is used to pass water and electrical pipes horizontally. Then, rock wool or glass wool is selected to be filled in the placement groove 106 (cavity) in the vertical keel body 100 to increase the sound insulation and heat preservation performance. There are two finishing methods for the keel. The first method is to use a base plate (magnesium oxide board / gypsum board, etc.) and lock it to the vertical keel body 100 with self-tapping screws. The surface can be pasted with a decorative integrated panel or puttyed and painted. Alternatively, the vertical keel body 100 can be dry-hung. The decorative integrated panel can be directly dry-hung on the surface (front and back) of the vertical keel body 100 to make its outer surface beautiful. The wall construction plan is now complete.

[0023] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
