Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a lightweight partition wall groove repair structure and process. Background Technology

[0002] Lightweight partition walls are a new type of panel material that has been promoted for use as non-load-bearing walls in buildings in recent years. Lightweight partition walls refer to prefabricated panels made of lightweight materials or with lightweight structures, featuring tenons, mortises, and joint grooves on both sides, and a density not exceeding the standard specified values ​​(90kg / m²: 90 panels, 110kg / m²: 120 panels). They are generally used as prefabricated panels for non-load-bearing interior partition walls in industrial and civil buildings. The raw materials used should comply with the JG / T169-2016 standard. Lightweight partition walls use cement as the main binding material, with industrial slag, fly ash, volcanic ash, polypropylene fiber, foamed perlite, etc., as additives, along with chemical additives. After thorough mixing, the mixture is cast into molds to obtain the product, which is then cut to the required length according to project needs before being used in buildings.

[0003] In current construction practice, lightweight partition walls are widely used as interior partitions in most apartment buildings and office buildings due to their economic advantages and ease of construction. Lightweight partition walls differ from traditional masonry aerated concrete block lightweight partition walls; their strength and thickness are inferior. Grooving during the construction of lightweight partition walls can easily damage their structure, leading to reduced strength and ultimately affecting their safety.

[0004] First, grooves are cut into the lightweight partition wall to install electrical boxes for both high-voltage and low-voltage wiring. Then, cement mortar or gypsum mortar is used to fill and repair the grooved wall. This traditional repair method has some drawbacks. For example, during the drying and shrinkage process, cement mortar or gypsum mortar may have a different shrinkage rate than the lightweight partition wall material, leading to weakened adhesion between the materials and causing cracks and damage. In addition, these traditional materials are relatively hard, which is incompatible with the flexibility of lightweight partition walls, making the wall more susceptible to damage when subjected to external impacts. Moreover, the weight of cement mortar may place additional load-bearing pressure on the lightweight partition wall, potentially affecting its stability and sound insulation.

[0005] Patent CN113279596B describes a method for repairing a lightweight partition wall by grooves, which involves: marking lines for positioning, cutting grooves, grinding the groove walls, erecting a support structure, pouring a side wall retaining wall, and sealing the groove. The grooves do not affect the strength of the lightweight partition wall and are used to prevent cracking or collapse. However, in this solution, the repair surface of the wall is small and the repair effect is poor. Furthermore, the material cost of the support structure after repair is high. If it is directly embedded in the lightweight wall, it can significantly increase the repair cost of the lightweight partition wall.

[0006] Existing filling and repair methods have failed to effectively solve the repair problems that are compatible with lightweight partition wall materials, especially in ensuring the overall performance of the wall, such as crack prevention and sound insulation. There is still considerable room for improvement. New repair materials or technologies need to be more compatible with lightweight partition walls, extend the service life of the walls, and maintain their inherent sound insulation and other properties. Summary of the Invention

[0007] The purpose of this invention is to provide a lightweight partition wall groove repair structure and process, which improves the mechanical strength of the grooved lightweight partition wall, ensures the safe use of the building, and facilitates the installation of electrical circuits.

[0008] This invention is achieved through the following technical solution:

[0009] A lightweight partition wall grooving repair structure is provided, in which a working groove is opened in the lightweight partition wall. A top plate is installed at the top and a bottom plate is installed at the bottom of the working groove. A first protective mesh plate is installed on the lower side of the top plate and the upper side of the bottom plate, respectively. A second protective mesh plate is installed on the left inner side and the right inner side of the working groove, respectively. A support adjustment component is provided on the inner side of the second protective mesh plate on the left inner side and the right inner side of the working groove. After adjusting the height of the support adjustment component, it is fixed so that its top and bottom are tightly pressed against the lower side of the top plate and the upper side of the bottom plate, respectively.

[0010] The top of the working trough is provided with a π-shaped limiting groove that connects to the working trough. A π-shaped locking block is fixedly installed at the top center of the top plate. The π-shaped locking block is engaged with the π-shaped limiting groove.

[0011] The gap between the second protective mesh and the working trench wall was filled with gypsum mortar.

[0012] To optimize the above technical solution, the specific measures / limitations also include:

[0013] The aforementioned support adjustment assembly is an X-shaped cross movable frame composed of two cross support rods. The cross center of the two support rods is connected by a rotatable shaft. The upper and lower ends of the two support rods are connected by distance adjustment rods, and the height is changed by adjusting the degree of cross between the two support rods through the distance adjustment rods.

[0014] The four ends of the X-shaped cross movable frame are all connected to the distance adjustment rods through mounting heads. The ends of the two supporting long rods are movably snapped into the mounting heads. The upper distance adjustment rods pass through the two upper mounting heads, and the lower distance adjustment rods pass through the two lower mounting heads.

[0015] Furthermore, a right-angle movable groove is provided inside the housing of the mounting head, and a U-shaped bayonet is provided on the groove wall of the right-angle movable groove. A positioning screw is threaded to the side of the U-shaped bayonet. The top and bottom of the support rod are provided with transverse locking posts, which are correspondingly engaged in the U-shaped bayonet. The locking posts can rotate within the right-angle movable groove of the mounting head housing and are limited by the positioning screw to prevent them from falling out.

[0016] Furthermore, the distance adjustment rod is a threaded straight rod, and a positioning hexagonal nut is installed on the threaded straight rod. The distance between the ends of the X-shaped cross movable frame is adjusted and fixed by loosening and tightening the positioning hexagonal nut on the distance adjustment rod.

[0017] The π-shaped limiting groove includes a longer horizontal groove at the top and two shorter vertical grooves at the bottom that connect the horizontal grooves. Between the two vertical grooves is a square wall block retained in the lightweight partition wall. The π-shaped locking block includes a longer horizontal block at the top and two shorter vertical blocks at the bottom that connect the horizontal block and the top plate. Between the two vertical blocks is an empty groove.

[0018] Both the first and second protective mesh panels are composed of a frame panel and a protective isolation mesh, which form an integrated component.

[0019] The protective isolation netting is selected from plastic netting, fiber netting, natural material netting, or composite material netting.

[0020] This invention also provides a lightweight partition wall grooving repair process, which adopts the above-mentioned lightweight partition wall grooving repair structure, forming the main frame inside the working groove through a top plate and a bottom plate; the wall at the top of the working groove is reinforced by correspondingly engaging a π-shaped limiting groove with a π-shaped locking block installed on the top plate; a first protective mesh plate is installed on the lower side of the top plate and the upper side of the bottom plate, and a second protective mesh plate is installed on the left inner side and the right inner side of the working groove; between the top plate and the bottom plate, the inner sides of the left and right inner protective mesh plates of the working groove are supported and fixed by a support adjustment component, and the gap between the second protective mesh plate and the wall of the working groove is filled with gypsum mortar.

[0021] Furthermore, the specific steps of the lightweight partition wall groove repair process are as follows:

[0022] Step 1: Cut grooves in the lightweight partition wall and cut a π-shaped limiting groove above the grooves.

[0023] Step 2: Place the top plate into the inner top of the working trough, and use the π-shaped locking block and the π-shaped limiting groove to lock and fix the top plate in place. Then, install and fix the bottom plate into the inner bottom of the working trough.

[0024] Step 3: Based on the dimensions of the top plate and bottom plate, and the dimensions of the left and right inner sides of the working trough, make the corresponding first protective net plate and second protective net plate, and fix them on the inner side wall of the working trough.

[0025] Step 4: Use the support adjustment assembly to support the top and bottom plates. Adjust the height of the support adjustment assembly so that its top and bottom ends are respectively pressed against the lower side of the top plate and the upper side of the bottom plate and then fixed.

[0026] Step 5: Fill the gap between the second protective mesh and the working trench wall with gypsum mortar.

[0027] The present invention also provides a method for installing an electrical box in a lightweight partition wall, characterized in that a working groove is opened in the lightweight partition wall, the working groove is repaired using the above-mentioned lightweight partition wall groove repair process, and after the repair is completed, an electrical box and an electrical tray are installed in the working groove, so that the electrical box is connected to the electrical tray, and cement is filled between the electrical tray and the working groove.

[0028] Compared with the prior art, the beneficial effects of the present invention are:

[0029] The lightweight partition wall grooving repair process of this invention, through the combined application of X-shaped cross-moving frames, side protective mesh panels, and gypsum mortar, can significantly improve the mechanical strength of the grooved lightweight partition wall. The π-shaped locking blocks between the top plate and the working groove provide stress relief for the working groove, preventing wall damage, maintaining the integrity of the lightweight partition wall structure during construction, and reducing repair difficulty. This invention uses a support adjustment component to provide support between the top and bottom plates. This support adjustment component is easy to disassemble and install, has a wide range of adjustment, and is convenient to operate, effectively applicable to working grooves of different sizes. This invention also uses a protective mesh panel to provide shock absorption protection for the inner side of the working groove.

[0030] This invention enhances structural stability by using a π-shaped limiting groove and a π-shaped locking block to interlock between the top plate and the working trough. The combination of the π-shaped limiting groove and the locking block provides a more robust connection. Compared to traditional repair materials, this not only strengthens the structural stability between the top plate and the working trough but also reduces deformation and cracking caused by repairs. It is also more effectively able to withstand impacts and vibrations that may occur during daily use. Furthermore, the π-shaped structure provides elasticity and buffer space, which can absorb and disperse stress caused by temperature changes or other external factors to a certain extent, compared to repairs using cement mortar or plaster mortar. It significantly reduces the risk of wall cracks and damage; facilitates installation and maintenance: the snap-fit ​​structural design simplifies the installation process and improves construction efficiency. Furthermore, when electrical wiring or circuit maintenance is needed, the clips can be easily removed from the limiting groove, facilitating access to the interior space of the wall and subsequent maintenance work; improves sound insulation: the matching design of the π-shaped limiting groove and the clips maintains the airtightness and integrity of the partition wall, thereby maintaining or even improving its sound insulation effect; enhances aesthetics: due to the tight snap-fit ​​between the clips and the limiting groove, the surface treatment achieves a flush appearance with the wall, providing a cleaner and more professional look.

[0031] This invention fills the gap between the protective mesh and the working trench wall with gypsum mortar, which can improve the strength of the wall repair: Gypsum mortar has good bonding properties, and after being filled into the gap between the protective mesh and the working trench wall, it can form a firm bond with the original wall material, enhancing the overall strength of the repaired area and reducing the fragility of the wall after grooving; it prevents the formation of cracks: Gypsum mortar has small volume changes during the curing process, reducing cracks caused by shrinkage and improving the overall stability of the wall, thereby avoiding partial or overall cracks and damage to the wall that may be caused by traditional repair materials; it also improves sound insulation performance: Gypsum mortar Its dense properties help block the propagation of sound waves, and the filled wall can maintain or improve its sound insulation effect, which is beneficial to improving the acoustic environment inside the residence; it speeds up the construction process: the curing time of gypsum mortar is relatively fast, which can shorten the waiting time for curing during the construction process, thereby improving work efficiency; it improves the surface treatment quality: the surface of gypsum mortar is smooth after drying, which provides a good base for subsequent wall decorations such as paint and wallpaper, which is conducive to improving the quality and aesthetics of wall decoration; it is environmentally friendly and healthy: gypsum mortar is an environmentally friendly material, which is beneficial to the health of the indoor environment of the building and the comfort of users.

[0032] In the lightweight partition wall grooving repair process of this invention, the sound insulation effect is improved in the following aspects: Sealing: The repair operation maintains or enhances the sealing of the wall, reducing the transmission of sound waves through the wall gaps, thereby improving the sound insulation effect; Material properties: Gypsum mortar itself has certain sound absorption characteristics, reducing the sound waves reflected by the wall and reducing the echo and resonance of noise in the room; Structural features: The structural construction increases the wall's ability to block and absorb sound waves; Avoiding cracks: Wall cracks can become sound wave propagation channels. The repair process helps to eliminate these potential sound leakage points by effectively filling and sealing cracks; Overall structural consistency: The consistency of the wall structure helps with sound insulation and avoids sound wave amplification caused by unevenness or voids in the structure. Restoring the consistency of the wall during the repair process helps to maintain its sound insulation characteristics.

[0033] The solution provided by this invention offers a convenient and efficient process for repairing and grooving lightweight partition walls. It effectively reduces structural damage to the lightweight partition wall after grooving, ensuring the strength of the lightweight partition wall, better guaranteeing the safe use of the building, facilitating the installation of indoor circuits, and providing good sound insulation performance.

[0043] The present invention will be further described in detail below through embodiments, but it should not be construed as limiting the scope of the subject matter of the present invention to the following embodiments. All technologies implemented based on the above content of the present invention fall within the scope of the present invention.

[0044] In one embodiment, the present invention proposes a lightweight partition wall groove repair structure, please refer to [link / reference]. Figure 1-4 A working trough 2 is opened in the lightweight partition wall 1. A top plate 3 is installed at the top and a bottom plate 4 is installed at the bottom of the working trough 2. The top plate 3 and the bottom plate 4 protect the inner top and inner bottom of the working trough 2, respectively. A first protective net plate 501 is installed on the lower side of the top plate 3 and the upper side of the bottom plate 4, respectively. A second protective net plate 502 is installed on the left inner side and the right inner side of the working trough 2, respectively. A support adjustment component is provided on the inner side of the second protective net plate 5 on the left inner side and the right inner side of the working trough 2. After adjusting the height of the support adjustment component, it is fixed so that its top and bottom are pressed against the lower side of the top plate 3 and the upper side of the bottom plate 4, respectively, to support the top plate 3 and the bottom plate 4 and ensure the stability of the top plate 3 and the bottom plate 4.

[0045] In this embodiment, the working trough 2 is preferably square in structure. In this embodiment, the four corners of the top plate 3 and the four corners of the bottom plate 4 are fixed to the inner wall of the working trough 2 by bolts.

[0046] The top of the working trough 2 is provided with a π-shaped limiting groove 201 that connects to the working trough 2. A π-shaped locking block 301 is fixedly installed at the top center of the top plate 3. The π-shaped locking block 301 is engaged with the π-shaped limiting groove 201. The matching engagement between the π-shaped limiting groove and the π-shaped locking block can enhance the structural stability, reduce cracks and damage, facilitate installation and maintenance, and improve the sound insulation effect.

[0047] The gap between the second protective mesh panel 502 and the wall of the working trough 2 is filled with gypsum mortar. This invention uses filling the gap between the second protective mesh panel and the wall of the working trough with gypsum mortar as a main reinforcement and fixing method. This not only facilitates the fixing of the electrical trough body and protects the wires from moisture or external damage, but also avoids sound wave amplification caused by uneven or hollow structures, thus contributing to the overall sound insulation effect.

[0048] The support adjustment assembly is an X-shaped cross movable frame 601 composed of two cross support rods. The cross center of the two support rods is connected by a rotatable shaft. The upper and lower ends of the two support rods are connected by distance adjustment rods. The height of the two support rods is changed by adjusting the degree of cross between them through the distance adjustment rods.

[0049] The four ends of the X-type cross movable frame 601 are all connected to the distance adjustment rods through the mounting heads. The ends of the two support rods are movably snapped to the mounting heads. The upper distance adjustment rods pass through the two upper mounting heads, and the lower distance adjustment rods pass through the two lower mounting heads.

[0050] Furthermore, a right-angle movable groove 6021 is provided inside the housing of the mounting head, and a U-shaped bayonet 6022 is provided on the groove wall of the right-angle movable groove 6021. A positioning screw 6023 is threaded to the side of the U-shaped bayonet 6022. The top and bottom ends of the support rod are provided with transverse locking posts 6011. The locking posts 6011 are correspondingly locked in the U-shaped bayonet 6022. The locking posts 6011 can rotate within the right-angle movable groove 6021 of the mounting head housing and are limited by the positioning screw 6023 to prevent them from falling out.

[0051] The distance adjustment rod is a threaded straight rod, and a positioning hexagonal nut 608 is installed on the threaded straight rod. The distance between the ends of the X-type cross movable frame 601 is adjusted and fixed by loosening and tightening the positioning hexagonal nut 608 on the distance adjustment rod.

[0052] In the embodiments, please refer to Figure 5 , Figure 6One top end of the X-shaped cross-mounted frame 601 is movably connected to the first upper mounting head 602, the other top end is movably connected to the second upper mounting head 603, one bottom end is movably connected to the first lower mounting head 605, and the other bottom end is movably connected to the second lower mounting head 606. The center of the X-shaped cross-mounted frame 601 is a rotatable shaft. An upper distance adjusting rod is connected between the first upper mounting head 602 and the second upper mounting head 603. The upper distance adjusting rod is an upper limit threaded straight rod 604. The first lower mounting head 605 is connected to the second lower mounting head 606. A lower distance adjusting rod is connected between the mounting heads 606. The lower distance adjusting rod is a lower limit threaded straight rod 607. The upper limit threaded straight rod 604 and the lower limit threaded straight rod 607 are respectively provided with adjusting components for adjusting the distance between the two mounting heads at the same end. The adjusting components are several positioning hexagonal nuts 608, which are respectively installed on both sides of the first upper mounting head 602, the second upper mounting head 603, the first lower mounting head 605, and the second lower mounting head 606 on the upper limit threaded straight rod 604 and the lower limit threaded straight rod 607.

[0053] In this embodiment, the first upper mounting head 602 is also fixed to the top plate 3 by screws, and the first lower mounting head 605 is also fixed to the bottom plate 4 by screws.

[0054] Specifically, the π-shaped limiting groove 201 includes an upper, longer horizontal groove and two lower, shorter vertical grooves that connect the horizontal grooves, with a square wall block retained on the lightweight partition wall 1 between the two vertical grooves; the π-shaped locking block 301 includes an upper, longer horizontal block and two lower, shorter vertical blocks that connect the horizontal block and the top plate 3, with an empty groove between the two vertical blocks.

[0055] Both the first protective mesh panel 501 and the second protective mesh panel 502 are composed of a frame panel 503 and a protective isolation mesh 504, which form an integrated component.

[0056] The selection of 504 stainless steel protective fencing should be based on the following aspects, depending on the actual construction conditions:

[0057] a. Environmental tolerance: Consider environmental factors such as temperature, humidity, corrosive gases or liquids;

[0058] b. Strength requirements: How much mechanical support or impact resistance is needed;

[0059] c. Economic costs;

[0060] d. The processing difficulty and installation methods of different materials;

[0061] e. Safety performance: non-flammable, insulating, non-toxic, etc.

[0062] Common materials include, but are not limited to:

[0063] Metal mesh: such as stainless steel mesh, aluminum alloy mesh, galvanized steel mesh, etc., is suitable for occasions that require corrosion resistance, high temperature resistance or a certain mechanical strength.

[0064] Plastic mesh: such as polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), etc., is suitable for occasions requiring lightweight, corrosion resistance, and insulation.

[0065] Fiber mesh: such as glass fiber, carbon fiber, etc., is suitable for applications requiring enhanced insulation performance and tensile strength.

[0066] Composite material mesh: This type of mesh combines the characteristics of different materials, such as metal and plastic, or fiber and plastic, and is used in applications with special requirements.

[0067] Natural material mesh: such as bamboo mesh, cotton mesh, etc., are more suitable for one-time or short-term use.

[0068] In another embodiment, the present invention proposes a lightweight partition wall grooving repair process, employing the aforementioned lightweight partition wall grooving repair structure. (See also...) Figure 7 The main frame of the working trough 2 is formed by the top plate 3 and the bottom plate 4. The wall at the top of the working trough 2 is reinforced by a π-shaped limiting groove 201 that is correspondingly engaged with a π-shaped locking block 301 installed on the top plate 3. A first protective net plate 501 is installed on the lower side of the top plate 3 and the upper side of the bottom plate 4, and a second protective net plate 502 is installed on the left inner side and the right inner side of the working trough 2, respectively. Between the top plate 3 and the bottom plate 4, the inner sides of the left and right inner protective net plates 5 of the working trough 2 are supported and fixed by a support adjustment component. The gap between the second protective net plate 502 and the wall of the working trough 2 is filled with gypsum mortar.

[0069] Furthermore, the specific steps of the lightweight partition wall groove repair process are as follows:

[0070] Step 1: Cut the working groove 2 on the lightweight partition wall and cut a π-shaped limiting groove 201 above the working groove 2;

[0071] Step 2: Place the top plate 3 into the inner top of the working trough 2, and use the π-shaped locking block 301 to engage with the π-shaped limiting groove 201 to install and fix the top plate 3. Then install and fix the bottom plate 4 into the inner bottom of the working trough 2.

[0072] Step 3: Based on the dimensions of the top plate 3 and the bottom plate 4, and the dimensions of the left and right inner sides of the working trough 2, make the corresponding first protective net plate 501 and second protective net plate 502, and fix them on the inner side wall of the working trough 2.

[0073] Step 4: Use the support adjustment assembly to support the top plate 3 and the bottom plate 4. Adjust the height of the support adjustment assembly so that its top and bottom ends are respectively pressed against the lower side of the top plate 3 and the upper side of the bottom plate 4 and then fixed.

[0074] Step 5: Fill the gap between the second protective mesh 502 and the wall of the working trench 2 with gypsum mortar.

[0075] A pre-reserved opening can be made above the gap for filling, effectively filling the gap at the repair site and improving the density of the repaired lightweight partition wall.

[0076] The process for filling with gypsum mortar is as follows:

[0077] Prepare plaster mortar: According to the manufacturer's instructions or industry standards, mix plaster powder with water in the specified proportions and stir to form a uniform paste.

[0078] Clean the gaps: Before filling, ensure that the surfaces inside the gaps are clean and free of dust, oil, and loose material to ensure that the gypsum mortar can adhere well.

[0079] Filling with plaster mortar: Tools used: Use a scraper, mortar gun or other suitable tools to press plaster mortar into the gap; start from one end of the gap and push evenly to the other end; ensure that the filler is deep into the gap and forms a tight bond between the protective mesh and the wall.

[0080] Leveling and finishing: Before the gypsum mortar begins to solidify, use a scraper or trowel to level and compact the filling surface; ensure that the gypsum mortar surface is flat, flush with the surrounding walls, or slightly recessed, to facilitate subsequent painting or coating work.

[0081] Drying and curing: Avoid strong vibrations or wind before the gypsum mortar cures to prevent cracks from forming; depending on the ambient temperature and humidity, gypsum mortar generally needs several hours to a day to dry and cure completely.

[0082] Grinding and coating: After the gypsum mortar has completely dried, any uneven areas on the surface can be ground appropriately; finally, the gypsum mortar surface can be brushed or coated as needed.

[0083] During the filling process, in order to ensure that the gypsum mortar does not leak or sink, some auxiliary tools or materials may be needed, such as filling paper tape, sealing tape or other leak-stopping materials, to support the gypsum mortar until it hardens.

[0084] In another embodiment, the present invention proposes a method for installing an electrical box in a lightweight partition wall. A working groove 2 is opened in the lightweight partition wall 1, and the working groove 2 is repaired using the above-mentioned lightweight partition wall groove repair process. After the repair is completed, an electrical box and an electrical tray are installed in the working groove 2, so that the electrical box is connected to the electrical tray. Cement is filled between the electrical tray and the working groove 2 to ensure the stability and sealing of the structure.

[0085] The electrical box will be installed in a suitable location on the wall, with its rear or side usually connected to the electrical conduit. The cable passes through the electrical conduit and finally enters the electrical box, where it is properly connected.

[0086] Explanation of relevant construction and engineering terminology:

[0087] Electrical cable trays (usually referring to cable ducts, conduits, or wire conduits) and electrical boxes (i.e., electrical distribution boxes, used to install electrical components such as switches, sockets, and circuit breakers) are two different components in electrical installation. Their installation relationship is usually as follows:

[0088] Electrical cable trays are channels used to protect and manage cables. They can be made of metal or plastic and run through walls, floors, or ceilings. After being channeled into lightweight partition walls, electrical cable trays are installed in the working channels to safely guide cables through the walls to electrical appliances or electrical boxes in other parts of the building.

[0089] Electrical box: usually refers to a distribution box or junction box. It is an enclosed space fixed to the wall for installing electrical equipment such as sockets, switches, circuit breakers, etc. Electrical boxes usually need to be fixed in the reserved space in the wall to facilitate wiring and installation of electrical components.

[0090] The present invention will be further described in detail below with reference to a specific construction embodiment:

[0091] The steps for repairing grooves in lightweight partition walls are as follows:

[0092] 1. Perform the grooving operation on the lightweight partition wall: draw a cutting line with a pencil at the grooving position of the lightweight partition wall, then cut the grooving, and cut a π-shaped limiting groove 201 above the grooving.

[0093] 2. Install the top plate 3 and the bottom plate 4: Place the top plate 3 into the inner top of the working groove 2, and use the π-shaped locking block 301 to engage with the π-shaped limiting groove 201. Install bolts at the four corners of the top plate 3 to install and fix the top plate 3. Similarly, install and fix the bottom plate 4 into the inner bottom of the working groove 2.

[0094] 3. Based on the dimensions of the top plate 3 and the bottom plate 4, and the dimensions of the left and right inner sides of the working trough 2, cut the protective isolation net to make the corresponding first protective net plate 501 and second protective net plate 502, and fix them to the inner side wall of the working trough 2 with screws.

[0095] 4. Use the support adjustment assembly to support the top plate 3 and the bottom plate 4. Adjust the distance between the first upper mounting head 602 and the second upper mounting head 603, and the distance between the first lower mounting head 605 and the second lower mounting head 606 on the upper limit threaded straight rod 604 and the lower limit threaded straight rod 607 by loosening the positioning hexagonal nut 608. This will deform the X-shaped cross movable frame 601 and adjust its height until the height of the X-shaped cross movable frame 601 is equal to the height difference between the top plate 3 and the bottom plate 4, so that its top and bottom are respectively pressed against the inner side of the top plate 3 and the inner side of the bottom plate 4. Then tighten the positioning hexagonal nut 608 to fix it.
