Description

Technical Field

[0001] This application relates to the field of construction, and in particular to a method for constructing a double-layer interior partition wall, installation tools for construction, and the double-layer interior partition wall itself. Background Technology

[0002] The construction location of double-layer interior partition walls can be selected according to actual needs. The common construction method of double-layer interior partition walls is to build a casting mold on site, and then pour the concrete on site. After the concrete is poured, it needs to be cured for a period of time to finally form a double-layer interior partition wall. Since the interior partition wall is formed by casting on site, the process of building the mold, pouring, and curing all require a lot of time, resulting in low efficiency in the construction of interior partition walls. Summary of the Invention

[0003] To improve the efficiency of constructing interior partition walls, this application provides a method for constructing a double-layer interior partition wall, installation tools for construction, and a double-layer interior partition wall.

[0004] Firstly, this application provides a method for constructing a double-layer internal partition wall, employing the following technical solution: A method for constructing a double-layer interior partition wall includes the following steps: S1. Construction preparation; The site was cleaned up, the installation location of the lightweight partition wall panels was determined at the construction site, and the lightweight partition wall panels were transported to the site for storage. S2. Cleaning the work surface; S3. According to the construction drawings, use a laser level to mark the wall edge lines and a chalk line to mark the control lines. S4. Install U-shaped steel clips on the lightweight partition wall panel; Sound-absorbing panels are installed on top of the lightweight partition wall panels, and U-shaped steel clips are installed at the locations where the lightweight partition wall panels need to be connected and fixed to the main building structure. S5. Use installation tools to install one side of the lightweight partition wall panel; S6. Use the installation tools to install the lightweight partition wall panel on the other side; S7. Fill the gaps between the lightweight partition boards on both sides and the ground, and cure them to form a double-layer interior partition wall.

[0005] By adopting the above technical solution, the steps of building molds, pouring, and curing are reduced in the process of constructing double-layer internal partition walls, which shortens the time required to construct double-layer internal partition walls and improves the efficiency of constructing double-layer internal partition walls.

[0006] Optionally, S5, the specific steps for installing one side of the lightweight partition wall panel using the installation tools are as follows: Use a trolley to transport the lightweight partition wall panel to the installation position, then tilt the lightweight partition wall panel to the side at a certain angle, and install two adjustable supports at the core-pulling hole at the bottom of the lightweight partition wall panel. Continue rotating the lightweight partition board until it is perpendicular to the ground. Then, use the installation tool to slowly move the lightweight partition board to the installation position. Leave a 30mm gap between the bottom wall of the lightweight partition board and the ground, a 10mm gap between the top surface of the lightweight partition board and the bottom surface of the floor slab, and a 5mm gap between two adjacent lightweight partition boards. Initially adjust the adjustable supports to move the lightweight partition wall panels upwards and press them firmly against the floor. Then, apply flame-retardant expanding foam to the joints of the lightweight partition wall panels. Use a pry bar to slowly move the lightweight partition wall panels so that the male and female grooves of two adjacent lightweight partition wall panels interlock. Squeeze out any excess expanding foam. Use a straightedge to check the flatness of the lightweight partition wall panels. If the flatness error of the panel surface is greater than 3mm, use a spare panel to replace it. After passing the test, fix the steel clips to the main building structure.

[0007] Optionally, S6, the specific steps for installing the other side of the lightweight partition wall using installation tools are as follows: Install the SHS silica insulation board at the junction of the main building and the lightweight partition wall. The remaining installation steps are the same as those in S5. When installing the other side of the lightweight partition wall, stagger the joints of the two sides of the lightweight partition wall by 300mm. After the other side of the lightweight partition wall is fixed, install the SHS silica insulation board with a height of 150mm at the bottom of the interlayer between the two sides of the lightweight partition wall.

[0008] Optionally, the specific steps for S7 are as follows: After the pipeline installation is completed, clean and moisten the area where the bottom of the lightweight partition board meets the ground, and fill the area with fine stone concrete.

[0009] Secondly, this application provides an installation tool for constructing a double-layer internal partition wall, employing the following technical solution: An installation tool for constructing a double-layer interior partition wall, applied to the above-mentioned construction method, includes a base plate, rollers installed on the lower surface of the base plate, a handle connected to one side of the base plate, and a vertical fixing plate connected to the base plate. The base plate has an installation groove on the side of the fixed plate away from the support rod. A sliding plate is provided in the installation groove. A slider is hinged to the bottom of the sliding plate. The slider is slidably connected to the base plate and slides along the arrangement direction of the sliding plate and the fixed plate. The base plate is also equipped with a drive assembly for controlling the movement and rotation of the sliding plate.

[0010] By adopting the above technical solution, in the initial state, the sliding plate is horizontal, and the upper surface of the sliding plate is lower than the upper surface of the base plate. The lightweight partition board is placed on the base plate, and the lightweight partition board is located between the fixed plate and the sliding plate. The drive component works to move the sliding plate closer to the fixed plate. At the same time, the drive component drives the sliding plate to rotate upward. When the sliding plate moves into position, the sliding plate is vertical and contacts the lightweight partition board. At this time, the sliding plate and the fixed plate cooperate to limit the lightweight partition board, reducing the possibility of the lightweight partition board tilting during movement.

[0011] After the lightweight partition wall panel is installed, the control drive component is activated to move and rotate the sliding plate until it returns to its initial position. The upper surface of the sliding plate is lower than the upper surface of the base plate. At this point, pulling the lever will pull out the base plate.

[0012] Optionally, a T-shaped slide rod corresponding to the slider is fixedly connected to the bottom of the mounting groove. The slide rod is slidably inserted into the slider, and the length direction of the slide rod is set along the sliding direction of the slider.

[0013] By adopting the above technical solution, the slider and the slide rod cooperate to enable the sliding plate and the base plate to slide together.

[0014] Optionally, the drive assembly includes an inclined plate connected to the lower surface of the base plate, the inclined plate being located on the side of the fixed plate away from the handle, and the upper surface of the inclined plate being inclined downward in the direction away from the fixed plate; A connecting sleeve is connected to the slider, and a drive rod that penetrates the base plate and is slidably inserted into the connecting sleeve is inserted into the connecting sleeve. The lower end of the drive rod is slidably connected to the inclined plate, and the upper end of the drive rod is hinged to a connecting block. The connecting block is slidably connected to the side wall of the sliding plate away from the fixed plate, and the connecting block slides along the height direction of the sliding plate. The drive assembly also includes a power component that can drive the slider to move.

[0015] By adopting the above technical solution, when the lightweight partition board is placed on the base plate, the power component pulls the slider, sliding plate, connecting sleeve, and drive rod to move closer to the fixed plate. At the same time, the inclined plate pushes the drive rod upward, causing the drive rod to push the sliding plate to rotate upward. When it is necessary to pull out the base plate, the power component is controlled to move the slider, sliding plate, connecting sleeve, and drive rod away from the fixed plate. At the same time, the sliding block and sliding groove cooperate to pull the drive rod downward. The drive rod drives the sliding plate to rotate downward through the connecting block. When the sliding plate, slider, and drive rod all return to their initial positions, the power component stops moving the sliding plate.

[0016] Optionally, the power component includes a gear rotatably connected to the lower surface of the base plate, with each gear corresponding to a slider. A support rod with a rectangular cross-section is connected to the end face of the gear. The support rod is aligned with the gear's axis. A rope winding wheel is inserted into the support rod, and a pull rope is wound around the rope winding wheel. The pull rope passes through the base plate and is fixed to the corresponding slider. A limit spring is connected to the slider, and the limit spring is fixed to the groove wall corresponding to the mounting groove. A support plate is provided between the sliding plate and the fixed plate. A support spring is connected to the support plate. The lower end of the support spring is fixed to the bottom wall of the mounting groove. A rack corresponding to each gear is connected to the support plate. The rack passes through the bottom plate and meshes with the gear.

[0017] By adopting the above technical solution, in the initial state, the support spring creates a certain distance between the support plate and the base plate. The lightweight partition board is placed on the support plate, and the lightweight partition board moves downward by pressing the support plate and the rack. At the same time, the support plate compresses the support spring. The rack drives the winding wheel to rotate through the gear and the support rod, winding the pull rope and causing the pull rope to pull the slider towards the fixed plate.

[0018] When the sliding plate needs to be reset, pull the rope reel off the support rod. At this time, the limit spring returns to its original shape and pushes the sliding plate away from the fixed plate. At the same time, pull the rope off the rope reel. After the sliding plate returns to its initial position, pull the lever to separate the base plate from the lightweight partition board. During this process, when the support plate loses contact with the lightweight partition board, the support spring returns to its original shape and pushes the support plate and rack upward. After the support plate returns to its initial position, reconnect the rope reel to the support rod.

[0019] Thirdly, this application provides a double-layer internal partition wall, which adopts the following technical solution: A double-layer interior partition wall, constructed using the above-mentioned construction method, includes a lightweight partition wall panel. The lightweight partition wall panel has a male groove and a female groove on both sides. The male groove and female groove of two adjacent lightweight partition wall panels are matched. Flame-retardant expanding foam is filled between the male groove and the female groove. The splicing joints of the lightweight partition wall panels on both sides are staggered. The top of one side of the lightweight partition wall panel is connected to a sound-absorbing panel, and the other side of the lightweight partition wall panel is equipped with SHS silica insulation board at the connection point with the main building. Each lightweight partition wall panel is fixed to the main building by U-shaped steel clips at the fixed position. The lightweight partition wall panel is equipped with an adjustable support at the bottom that contacts the ground. The bottom of the interlayer between the two lightweight partition wall panels is filled with SHS silica insulation board. The junction between the bottom of the lightweight partition wall panel and the ground is filled with fine stone concrete.

[0020] By adopting the above technical solution, the steps for constructing double-layer internal partition walls are reduced, and the efficiency of constructing double-layer internal partition walls is improved.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. By carrying out steps such as construction preparation, work surface cleaning, defense line, installation of steel clips, and installation of lightweight partition wall panels, the efficiency of constructing double-layer internal partition walls has been improved; 2. By setting up a base plate, a fixed plate, a sliding plate, and a drive assembly, the likelihood of lightweight partition walls tipping over during movement can be reduced; 3. By setting up lightweight partition boards, steel clips, sound-absorbing boards, SHS silica insulation boards, and adjustable supports, the efficiency of constructing double-layer interior partition walls can be improved.

[0028] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0029] This application discloses a method for constructing a double-layer internal partition wall. It includes the following steps: S1. Construction preparation; Before construction, the lightweight partition wall panel 1 is designed using the apartment type as a unit module, taking into full consideration the installation positions of the electrical boxes and wiring channels, and a layout drawing is formed. The production unit of the lightweight partition wall panel 1 produces and processes according to the layout drawing and packages it according to the apartment type. The site is cleaned up, and the installation position of the lightweight partition wall panel 1 is determined on the construction site. The pads are placed on the flat ground, and the packaged lightweight partition wall panels 1 are transported to the site for storage. The lightweight partition wall panels 1 are stacked on the pads to keep them at a distance from the ground.

[0030] S2. Cleaning the work surface; Remove the laitance, dust, and debris from the location where the lightweight partition wall 1 will be installed on the main body of the building, thereby cleaning the location where the lightweight partition wall 1 will be installed on the main body of the building.

[0031] S3. According to the construction drawings, use a laser level to mark the wall edge lines and a chalk line to mark the control lines. After the lines are laid out, an inspection and verification are required. If they are not up to standard, the wall edge lines are laid out again using a laser level and the control lines are laid out again using a chalk line until the lines are approved.

[0032] S4. Install U-shaped steel clips 15 on the lightweight partition wall panel 1; First, a 50mm wide polyester fiber sound-absorbing panel 13 is installed on the top of the lightweight partition wall panel 1. Then, a U-shaped steel clip 15 is installed on the top of the lightweight partition wall panel 1, and U-shaped steel clips 15 are installed at the positions where the lightweight partition wall panel 1 needs to be connected and fixed to the main building.

[0033] S5. Use installation tools to install one side of the lightweight partition wall panel 1; Use a trolley to transport the lightweight partition wall panel 1 to the installation position. Then, tilt the lightweight partition wall panel 1 to its side at a certain angle and install two adjustable supports 16 at the bottom of the lightweight partition wall panel 1. The adjustable supports 16 are located at the core-pulling holes of the lightweight partition wall panel 1. Continue to rotate the lightweight partition wall panel 1 until it is perpendicular to the ground. Then, transfer the lightweight partition wall panel 1 to the installation tool and use the installation tool to slowly move the lightweight partition wall panel 1 to the installation position. Leave a 30mm gap between the bottom wall of the lightweight partition wall panel 1 and the ground, a 10mm gap between the top surface of the lightweight partition wall panel 1 and the bottom surface of the floor slab, and a 5mm gap between two adjacent lightweight partition wall panels 1.

[0034] Adjust the adjustable support 16 to move the lightweight partition wall panel 1 upward and press it against the floor. Then apply flame-retardant expanding foam to the joints of the lightweight partition wall panel 1. Use a pry bar to slowly move the lightweight partition wall panel 1 so that the male groove 11 and female groove 12 of two adjacent lightweight partition wall panels 1 engage, squeezing out excess expanding foam. Use a straightedge to check the flatness of the lightweight partition wall panel 1. If the flatness error of the panel is greater than 3mm, use a spare panel to replace it. After the flatness check is qualified, fix the steel clip 15 to the main building structure. The steel clip 15 can be fixed by welding or nailing.

[0035] S6. Use the installation tools to install the lightweight partition wall panel 1 on the other side; SHS silica insulation board 14 is installed at the junction of the main building and the lightweight partition wall 1. The remaining installation steps are the same as those in S5. When installing the other lightweight partition wall 1, the splicing gaps of the two lightweight partition wall 1 are staggered by 300mm. After the other lightweight partition wall 1 is fixed, an SHS silica insulation board 14 with a height of 150mm is installed at the bottom of the interlayer between the two lightweight partition wall 1.

[0036] S7. Fill the gap between the lightweight partition wall panels 1 on both sides and the ground, and cure them to finally form a double-layer inner partition wall.

[0037] After the pipeline installation is completed, clean and moisten the bottom of the lightweight partition wall 1 where it meets the ground, and fill the area with fine stone concrete.

[0038] The above steps enable the construction of double-layered internal partition walls. This eliminates the need for operators to build molds, pour concrete, or perform curing, thus reducing the time required and improving the efficiency of the construction.

[0039] This application also discloses an installation tool for constructing a double-layer internal partition wall, applied to the above-described construction method. The installation tool is used to move the lightweight partition wall panel 1, as described above. Figure 1 and Figure 2 The system includes a base plate 2, on which rollers are installed. A horizontally arranged handle 21 is fixedly connected to one side wall of the base plate 2. A fixing plate 3 is vertically fixedly connected to the base plate 2. An installation groove 22 is provided on the base plate 2. The installation groove 22 is located on one side of the fixing plate 3. The side of the installation groove 22 away from the fixing plate 3 penetrates the corresponding side wall of the base plate 2.

[0040] Reference Figure 2 and Figure 3The mounting groove 22 is provided with a sliding plate 4, the length direction of the sliding plate 4 is set along the length direction of the fixed plate 3, and the sliding plate 4 and the fixed plate 3 are parallel to each other. The sliding plate 4 and the fixed plate 3 are arranged along the length direction of the handle 21. A slider 41 is hinged to the lower surface of the sliding plate 4. In this embodiment, there are two sliders 41. A sliding rod 23 corresponding to the slider 41 is fixedly connected to the bottom wall of the mounting groove 22. The cross section of the sliding rod 23 is T-shaped. The length direction of the sliding rod 23 is set along the length direction of the handle 21. The sliding rod 23 and the slider 41 are slidably inserted. The sliding rod 23 and the slider 41 cooperate to allow the sliding plate 4 to slide on the base plate 2.

[0041] The base plate 2 is also provided with a drive assembly 5. The drive assembly 5 can drive the sliding plate 4 to move and rotate. The drive assembly 5 includes an inclined plate 51 fixedly connected to the lower surface of the base plate 2. The inclined plate 51 is located on the side of the fixed plate 3 away from the handle 21. The inclined plate 51 gradually tilts downward in the direction away from the handle 21. A drive rod 52 is provided above the inclined plate 51. In this embodiment, there are two drive rods 52. The two drive rods 52 are arranged along the length direction of the sliding plate 4. The lower end of the drive rod 52 is fixedly connected to a sliding block 521. The upper surface of the inclined plate 51 is provided with a sliding groove 511 that corresponds to the sliding block 521. The sliding groove 511 and the sliding rod 23 are in the same length direction. The sliding block 521 is slidably inserted into the corresponding sliding groove 511.

[0042] The drive rod 52 passes through the base plate 2 and is slidably inserted into the base plate 2. The upper end of the drive rod 52 is hinged to a connecting block 522. The sliding plate 4 has a connecting groove 42 on its side wall away from the fixed plate 3, which corresponds to the connecting block 522. The length direction of the connecting groove 42 is set along the height direction of the sliding plate 4. The connecting block 522 is slidably inserted into the corresponding connecting groove 42. Each slider 41 is fixedly connected to a connecting sleeve 53. Each drive rod 52 is slidably inserted into the corresponding connecting sleeve 53. When the slider 41 moves, the slider 41 can drive the drive rod 52 to move through the connecting sleeve 53.

[0043] The drive assembly 5 also includes a power component 54 that drives the sliding plate 4 to move. The power component 54 includes gears 541 that correspond one-to-one with the drive rod 52. The gears 541 are rotatably connected to the lower surface of the base plate 2. A coaxial support rod 542 is fixedly connected to one end face of the gears 541. The support rod 542 has a rectangular cross section. A rope winding wheel 543 is inserted into the support rod 542. The support rod 542 and the rope winding wheel 543 are detachable. The rope winding wheel 543 is coaxial with the gear 541. The gear 541 can drive the rope winding wheel 543 to rotate through the support rod 542.

[0044] A pull rope 544 is wound on the rope reel 543. One end of the pull rope 544 passes through the base plate 2 and is fixed to the corresponding slider 41. A limit spring 545 is also fixedly connected to the slider 41. The end of the limit spring 545 away from the slider 41 is fixed to the groove wall corresponding to the mounting groove 22. A support plate 546 is provided above the base plate 2. A rack 547 corresponding to the gear 541 is fixedly connected to the lower surface of the support plate 546. The rack 547 passes through the base plate 2 and meshes with the corresponding gear 541. The two slide rods 23 are located between the two racks 547. A support spring 548 is fixedly connected to the lower surface of the base plate 2. In this embodiment, there are two support springs 548. The lower end of the support spring 548 is fixed to the bottom wall of the mounting groove 22.

[0045] In the initial state, the support spring 548 supports the support plate 546, so that there is a certain distance between the surfaces of the support plate 546 and the base plate 2 that are close to each other. At this time, the rack 547 and the gear 541 mesh, and the limiting spring 545 moves the slider 41 and the drive rod 52 away from the fixed plate 3. The drive rod 52 is located on the lower side of the inclined plate 51. The drive rod 52 limits the sliding plate 4 through the connecting block 522, so that the sliding plate 4 is horizontal and the upper surface of the sliding plate 4 is lower than the upper surface of the base plate 2.

[0046] When it is necessary to move the lightweight partition wall panel 1 to the installation position, place the lightweight partition wall panel 1 on the support plate 546, so that the lightweight partition wall panel 1 is located between the fixed plate 3 and the sliding plate 4, and both long side walls of the lightweight partition wall panel 1 are flush with the corresponding side walls of the support plate 546. The lightweight partition wall panel 1 moves downward by pressing down on the support plate 546 and rack 547, while the support plate 546 compresses the support spring 548. The movement of the rack 547 drives the gear 541, support rod 542, and rope winding wheel 543 to rotate. The rotation of the rope winding wheel 543 winds and coils the pull rope 544, thereby causing the pull rope 544 to pull the slider 41, sliding plate 4, connecting sleeve 53, and drive rod 52 towards the support plate 546. At the same time, the inclined plate 51 pushes the drive rod 52 upward, causing the drive rod 52 to push the sliding plate 4 to rotate upward. When the support plate 546 stops moving downward, the sliding plate 4 moves to contact the support plate 546, and the support plate 546 contacts the fixed plate 3. At this time, the drive rod 52 makes the sliding plate 4 vertical. Therefore, the sliding plate 4 and the fixed plate 3 cooperate to limit the movement of the lightweight partition wall panel 1, reducing the possibility of the lightweight partition wall panel 1 tilting during the movement.

[0047] After the lightweight partition wall panel 1 is moved into place, when the base plate 2 needs to be pulled out, the operator pulls the rope reel 543 to separate the rope reel 543 from the support rod 542. At this time, the limit spring 545 returns to its original shape and pushes the slider 41, connecting sleeve 53, drive rod 52 and sliding plate 4 to move away from the support plate 546. The slider 41 moves and pulls the pull rope 544 out of the rope reel 543. At the same time, the sliding block 521 cooperates with the sliding groove 511 to make the drive rod 52 move downward. The drive rod 52 pulls the sliding plate 4 downward through the connecting block 522. When the limit spring 545 returns to its initial state, the sliding plate 4 is horizontal, and at this time the upper surface of the sliding plate 4 is lower than the upper surface of the support plate 546.

[0048] Then, pull the lever 21 away from the lightweight partition board 1. When the support plate 546 is no longer in contact with the lightweight partition board 1, the support spring 548 returns to its original shape and pushes the support plate 546 and the rack 547 upward. The movement of the rack 547 drives the gear 541 and the support rod 542 to rotate. When the support spring 548 returns to its initial state, the support plate 546 returns to its initial position. At this time, the operator reconnects the rope reel 543 to the support rod 542.

[0049] The implementation principle of an installation tool for constructing a double-layer internal partition wall according to an embodiment of this application is as follows: a lightweight partition wall panel 1 is placed on a support plate 546, a fixing plate 3 is in contact with the lightweight partition wall panel 1, the lightweight partition wall panel 1 pushes the support plate 546 downward, the rope wheel 543 rotates and pulls the slider 41, the sliding plate 4 and the drive rod 52 to move, and at the same time the drive rod 52 pushes the sliding plate 4 to rotate upward; when the support plate 546 stops moving, the sliding plate 4 is in a vertical state and the sliding plate 4 is in contact with the lightweight partition wall panel 1.

[0050] When the base plate 2 needs to be removed, the rope reel 543 is pulled off the support rod 542. The limiting spring 545 returns to its original shape and pushes the slider 41, the sliding plate 4, and the drive rod 52 to move. At the same time, the drive rod 52 pulls the sliding plate 4 to rotate downward. When the limiting spring 545 returns to its initial state, the upper surface of the sliding plate 4 is lower than the upper surface of the support plate 546. Pull the lever 21 to move the base plate 2 to separate from the lightweight partition wall 1. During this process, after the support plate 546 loses contact with the lightweight partition wall 1, the support spring 548 returns to its original shape and pushes the support plate 546 to move back to its original position. Finally, the rope reel 543 is inserted into the support rod 542.

[0051] This application also discloses a double-layer internal partition wall, constructed using the above-described construction method. Reference Figure 4 and Figure 5The system includes a lightweight partition wall panel 1. The lightweight partition wall panel 1 has a male groove 11 and a female groove 12 on both sides. The male groove 11 and female groove 12 of two adjacent lightweight partition wall panels 1 are matched. Flame-retardant expanding foam is filled between the male groove 11 and the female groove 12. The splicing seams of the lightweight partition wall panels 1 on both sides are staggered. In this embodiment, the splicing seams of the lightweight partition wall panels 1 on both sides are spaced 300mm apart.

[0052] One side of the lightweight partition wall panel 1 has a sound-absorbing panel 13 connected to its top, while the other side has SHS silica insulation boards 14 installed at the connection points between the lightweight partition wall panel 1 and the main building structure. Each lightweight partition wall panel 1 is fixed to the main building structure using U-shaped steel clips 15. The bottom of the lightweight partition wall panel 1 is equipped with an adjustable support 16 that contacts the ground. The bottom of the interlayer between the two lightweight partition wall panels 1 is filled with SHS silica insulation boards 14, and the junction between the bottom of the lightweight partition wall panel 1 and the ground is filled with fine stone concrete.

[0053] When constructing double-layer interior partition walls, the above-mentioned construction method can be used to directly employ prefabricated lightweight partition wall panels 1, reducing the steps of building molds, pouring, and curing, saving the time required to construct double-layer interior partition walls, thereby improving the efficiency of constructing double-layer interior partition walls.

[0054] This application also discloses an implementation principle of a double-layer internal partition wall: a prefabricated lightweight partition wall panel 1 is used and installed using the above-mentioned construction method to finally form a double-layer internal partition wall.

[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
