Description

Technical Field

[0001] The present invention relates to the technical field of curtain walls, in particular to modular GRC wall panels, GRC panels and GRC curtain walls. Background Art

[0002] A GRC wall panel is a kind of glass fiber reinforced cement board made of cement as a gelling material and alkali-resistant glass fiber filaments as a reinforcing material, formed by mechanical spraying or automated flow rolling. A GRC curtain wall is a building formed by connecting and fixing a GRC wall panel to a keel frame, and the GRC wall panel is supported by the keel frame. GRC curtain walls are mostly used for special-shaped buildings with complex and changeable shapes.

[0003] In the prior art, the installation of GRC wall panels on the keel frame is mostly carried out by fastening the GRC wall panel and the keel frame with a plurality of bolts and nuts. However, the fixing method using a large number of bolts and nuts is not only complicated in operation, but also the bolts and nuts exposed to the outside for a long time are prone to be eroded by the environment, affecting the stability of the installation of the GRC wall panel on the keel frame, and prone to the phenomenon of the GRC wall panel falling off. Summary of the Invention

[0004] The present application provides a GRC curtain wall, which can conveniently realize the installation of a GRC wall panel on a keel frame, avoid the trouble of using a plurality of bolts and nuts to connect the GRC wall panel and the keel frame, and reduce the possibility of the GRC wall panel falling off the keel frame.

[0005] The modular GRC wall panels, GRC panels and GRC curtain walls provided by the present application adopt the following technical solutions:

[0006] The GRC curtain wall includes a mounting plate and a keel frame; a mounting groove is provided on the side wall of the mounting plate; a GRC wall panel is installed in the mounting groove; the keel frame is installed on the side wall of the mounting plate away from the GRC wall panel; a pair of first cavities are provided in the mounting plate; a pair of first sliding grooves are provided on the inner side wall of the mounting groove; on the inner side wall of the end faces of the pair of first cavities close to each other, a first through hole communicating with the first sliding groove is provided; a push plate is slidably connected in the first through hole; a clamping plate is fixedly connected to the side wall of the push plate close to the GRC wall panel; the clamping plate is slidably matched with the inner side wall of the first sliding groove; a straight plate is slidably connected to the inner side wall of the pair of first cavities; the end faces of the pair of straight plates close to each other are respectively fixedly connected to the side walls of the pair of push plates away from the clamping plate; a driving component for driving the straight plate to slide towards the direction close to the GRC wall panel is provided on the side wall of the pair of straight plates away from the push plate, and a fixing part for fixing the keel frame is provided on the side wall of the straight plate close to the push plate.

[0007] By adopting the above technical solution, the GRC wallboard is installed in the installation groove of the installation plate, and the installation plate supports the GRC wallboard. Then, the installation plate is installed on the keel frame. The straight plate is driven by the driving component to slide towards the direction close to the GRC wallboard. During the sliding process of the straight plate, the push plate is driven to slide along the first through hole, so that the clamping plate slides towards the direction close to the GRC wallboard, and the GRC wallboard is clamped by the clamping plate, improving the stability of the GRC wallboard in the installation groove. Moreover, during the sliding process of the straight plate, the fixing component is driven to fix the installation plate and the keel frame, thus realizing the convenient installation of the GRC wallboard on the keel frame, avoiding the trouble of using multiple screws and bolts to connect the GRC wallboard and the keel frame, and reducing the possibility of the GRC wallboard falling off the keel frame.

[0008] Preferably, the driving component includes a first spring and a first threaded rod. One end of the first spring is connected to the side wall of the straight plate far from the push plate, and the end of the first spring far from the straight plate is connected to the inner side wall of the first cavity. A first threaded hole is provided on the inner side wall of the first cavity connected to the first spring. The first threaded rod is threadedly connected in the first threaded hole. The end of the first threaded rod extending into the first cavity contacts the side wall of the straight plate far from the push plate.

[0009] By adopting the above technical solution, when the GRC wallboard is installed into the installation groove, the first threaded rod is rotated, so that the end of the first threaded rod extrudes the straight plate to slide and stretches the first spring. During the sliding process of the straight plate, the clamping plate is driven to slide towards the direction close to the GRC wallboard, so that the clamping plate clamps the GRC wallboard, improving the stability of the GRC wallboard in the installation groove.

[0010] Preferably, a pair of jacks are provided on the side wall of the installation plate far from the installation groove. A pair of plug plates that can be inserted into the jacks are fixedly connected to the side wall of the keel frame close to the installation plate. Second through holes communicating with the pair of jacks one by one are provided on the inner side walls of the pair of first cavities close to each other. The fixing component includes a clamping block. The clamping block is fixedly connected to the side wall of the straight plate close to the push plate, and the clamping block is slidably matched with the inner side wall of the second through hole. A clamping hole matched with the clamping block is provided on the side wall of the plug plate close to the clamping block.

[0011] By adopting the above technical solution, after aligning the jacks on the installation plate with the plug plates on the keel frame, the plug plates are embedded into the jacks. During the process of the straight plate being extruded and sliding, the clamping block on the straight plate is driven to slide along the second through hole. The fixing between the installation plate and the keel frame is realized by embedding the clamping block into the clamping hole, so that the installation plate is kept stable on the keel frame.

[0012] Preferably, a rubber sheet is fixedly connected to the end face of the clamping plate far from the contact with the push plate.

[0013] By adopting the above technical solution, when the clamping plate squeezes and clamps the GRC wall panel, the rubber sheet arranged on the end face of the clamping plate is deformed under pressure and closely adheres to the side wall of the GRC wall panel. The arranged rubber sheet increases the friction force at the contact part between the clamping plate and the GRC wall panel, improves the clamping effect of the clamping plate, and makes it difficult for the GRC wall panel to fall off from the installation groove.

[0014] The combined GRC wall panel, based on the above GRC curtain wall, comprises a plurality of panels spliced with each other; placing grooves are arranged on the side walls where adjacent panels are in contact; fixing blocks for connecting adjacent panels are installed in the placing grooves; a second cavity is arranged inside the fixing blocks; fixing holes are arranged on the inner side wall at the bottom end of the placing grooves; a pair of third through holes matched with the fixing holes are arranged on the inner side wall at the bottom end of the second cavity; the pair of third through holes correspond to the positions of the fixing holes in a pair of mutually fitting placing grooves one by one, and insertion blocks which can be embedded into the fixing holes are slidably connected in the pair of third through holes; limiting grooves are arranged on the inner side walls of the pair of third through holes away from each other; limiting plates are fixedly connected to the side walls of the pair of insertion blocks away from each other; the pair of limiting plates are slidably connected in the limiting grooves, and a second spring is connected to the bottom surface of the limiting plates; the end of the second spring away from the limiting plate is connected to the inner side wall at the bottom end of the limiting groove; a driving mechanism for driving the pair of insertion blocks to be embedded into the fixing holes is arranged in the second cavity.

[0015] By adopting the above technical solution, when splicing a plurality of panels with each other, place the fixing blocks in the placing grooves on the side walls of the mutually spliced panels, and push the insertion blocks to slide along the third through holes through the driving mechanism, so that the insertion blocks are embedded into the fixing holes to realize the fixed connection between adjacent panels; during the sliding process of the insertion blocks, the limiting plates slide along the limiting grooves, and the cooperation between the limiting plates and the limiting grooves makes it difficult for the insertion blocks to extend out of the second through holes excessively, which is convenient for the driving mechanism to push the insertion blocks to slide, and the setting of the second spring is convenient for the return sliding of the insertion blocks.

[0016] Preferably, a first inclined surface is arranged on the top surface of the insertion block; the driving mechanism comprises a pair of sliders; the pair of sliders are slidably connected inside the second cavity, and first rounded corners matched with the first inclined surface are arranged on the bottom surfaces of the pair of sliders; third springs are connected to the side walls of the pair of sliders away from each other; the ends of the third springs away from the sliders are connected to the inner side wall of the second cavity; an extrusion assembly for driving the pair of sliders to slide in the direction away from each other is arranged in the second cavity.

[0017] By adopting the above technical solution, the extrusion assembly is used to push the pair of sliders to slide in the direction away from each other. During the sliding process of the sliders, the sliders squeeze the insertion blocks to slide down through the cooperation between the first rounded corners and the first inclined surface, so that the insertion blocks are embedded into the fixing holes to realize the connection between adjacent panels. The setting of the second spring enables the sliders to return to slide when not under the action of the extrusion force.

[0018] Preferably, a second inclined surface is provided on the side walls of a pair of sliding blocks that are close to each other; a second threaded hole is provided on the inner wall at the top of the second cavity; the extrusion assembly includes a pressure plate; the pressure plate is slidably connected to the inner wall of the second cavity, and a fourth spring is connected to the bottom surface of the pressure plate; the end of the fourth spring away from the pressure plate is connected to the inner wall of the bottom end of the second cavity; a second fillet matching the second inclined surface is provided on the side wall of the pressure plate close to the second inclined surface; a second threaded rod is threadedly connected to the second threaded hole; the bottom end of the second threaded rod is in contact with the top surface of the pressure plate.

[0019] By adopting the above technical solution, the second threaded rod is rotated so that the second threaded rod pushes the pressure plate to slide. With the cooperation of the second fillet on the side wall of the pressure plate and the second inclined surface on the side wall of the slider, a pair of sliders slide away from each other during the sliding process of the pressure plate, thereby causing the slider to squeeze the plug block into the fixing hole to realize the connection between adjacent panels.

[0020] Preferably, a countersunk hole is provided on the top surface of the fixing block at a position corresponding to the second threaded hole; the countersunk hole is coaxial with the second threaded hole.

[0021] By adopting the above technical solution, the countersunk hole arranged on the top surface of the fixing block plays a role of giving way, so as to accommodate the larger head of the second threaded rod and facilitate the installation of the GRC wall panel into the installation groove.

[0022] Preferably, a guide rod is fixedly connected to the inner side wall of the bottom end of the second cavity; the top end of the guide rod passes through the pressure plate and extends to contact the inner side wall of the top end of the second cavity; the pressure plate and the outer side wall of the guide rod are slidably matched.

[0023] By adopting the above technical solution, the guide rod plays a role of limiting the pressing plate during the movement of the pressing plate, so that the pressing plate is not easily offset during the sliding process.

[0024] The GRC panel is based on the above-mentioned combined GRC wall panel and comprises a panel; a sound insulation layer is arranged inside the panel.

[0025] By adopting the above technical solution, the sound insulation layer arranged inside the panel enables the panel to have a good sound insulation effect after being assembled as a whole, thereby reducing the possibility of noise from the external environment being transmitted to the interior of the building.

[0026] In summary, this application has the following beneficial effects:

[0027] 1. Install the GRC wall panel into the installation groove of the installation plate, support the GRC wall panel through the installation plate, then align the jack holes on the side wall of the installation plate with the plug plates on the side wall of the keel frame, so that the plug plates are inserted into the jack holes. Rotate the first threaded rod to make the first threaded rod squeeze the straight plate to slide. The straight plate pushes the push plate and the clamping block to slide along the first through hole and the second through hole respectively. The push plate pushes the clamping plate to clamp the GRC wall panel, improving the stability of the GRC wall panel in the installation groove; The clamping block is inserted into the clamping hole under the pushing action of the straight plate, thus realizing the fixation between the installation plate and the keel frame, and further realizing the convenient installation of the GRC wall panel on the keel frame, avoiding the trouble of connecting the GRC wall panel and the keel frame through screws and nuts, and reducing the possibility of the GRC wall panel falling off the keel frame;

[0028] 2. When assembling the panels, place the fixing block in the placement groove on the side wall of the mutually spliced panels. Rotate the second threaded rod to make the second threaded rod push the pressing plate to slide down, so that the pressing plate pushes a pair of sliders to slide in the mutually away direction, making the sliders squeeze the insertion blocks to slide down along the second through hole and embed into the fixing holes, thus realizing the connection of adjacent panels, and further making multiple panels combine into a GRC wall panel. The volume of a single panel is small, which is convenient for transportation, and the assembly method is simple and convenient, facilitating the on-site assembly of the GRC wall panel;

[0029] 3. A polyester fiber board is provided inside each single panel. The polyester fiber board has good sound insulation effect. By setting the polyester fiber board inside the panel for sound insulation, the overall assembled panel has good sound insulation effect, reducing the possibility of external environmental noise transmitting into the building interior.

[0037] The present invention will be further described in detail below with reference to the accompanying drawings. The same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper", "lower", "bottom surface" and "top surface" used in the following description refer to the directions in the accompanying drawings, and the terms "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.

[0038] The present invention discloses a GRC curtain wall, as Figure 1 shown, which includes a mounting plate 1, a keel frame 2 and a GRC wall panel 3; a mounting groove 11 is provided on the side wall of the mounting plate 1; the GRC wall panel 3 is installed inside the mounting groove 11; the keel frame 2 is installed on the side wall of the mounting plate 1 away from the GRC wall panel 3; the keel frame 2 is formed by welding a plurality of horizontal beams and a plurality of vertical beams.

[0039] First, the GRC wall panel 3 is installed in the mounting groove 11 of the mounting plate 1, and then the mounting plate 1 with the GRC wall panel 3 installed is installed on the side wall of the keel frame 2, so as to realize the installation of the GRC wall panel 3 on the keel frame 2.

[0040] As Figure 1 and Figure 2As shown in the figure, a pair of first cavities 12 are provided inside the mounting plate 1, which are respectively located on both sides of the mounting groove 11; first sliding grooves 13 are provided on the two inner side walls of the mounting groove 11 close to the first cavities 12; first through holes 14 communicating the first sliding grooves 13 with the first cavities 12 are provided on the inner side walls of the first sliding grooves 13 close to the first cavities 12; a push plate 141 is slidably connected in the first through hole 14, and a clamping plate 142 slidably matched with the inner side wall of the first sliding groove 13 is fixedly connected to the side wall of the push plate 141 close to the GRC wall panel 3; a straight plate 121 is slidably connected in each of the pair of first cavities 12, end faces of the pair of straight plates 121 close to each other are respectively fixedly connected to the side walls of the pair of push plates 141 away from the clamping plates 142, and a driving assembly 15 for driving the straight plate 121 to slide towards the GRC wall panel 3 is provided on the side walls of the pair of straight plates 121 away from the push plates 141; rubber sheets 143 are fixedly connected to the end faces of the pair of clamping plates 142 away from the push plates 141.

[0041] By driving the straight plate 121 to slide through the driving assembly 15, the push plate 141 is driven to slide towards the GRC wall panel 3 during the sliding process of the straight plate 121, so that the clamping plates 142 on both sides of the GRC wall panel 3 gradually approach the side wall of the GRC wall panel 3 and clamp the GRC wall panel 3, enabling the GRC wall panel 3 to be stable in the mounting groove 11. The rubber sheets 143 provided on the end faces of the clamping plates 142 increase the friction force at the contact part between the clamping plates 142 and the GRC wall panel 3, improving the stability of the GRC wall panel 3 in the mounting groove 11 and making the GRC wall panel 3 not easy to fall off.

[0042] As Figure 2 shown in the figure, the driving assembly 15 includes a first spring 151 and a first threaded rod 152. One end of the first spring 151 is connected to the side wall of the straight plate 121 away from the push plate 141, the end of the first spring 151 away from the straight plate 121 is fixedly connected to the inner side wall of the first cavity 12 away from the first through hole 14, and a first threaded hole 122 is provided on the inner side wall of the first cavity 12 connected to the first spring 151; the first threaded rod 152 is threadedly connected in the first threaded hole 122, and the end of the first threaded rod 152 close to the straight plate 121 contacts the end face of the straight plate 121 away from the push plate 141.

[0043] In the initial state, the first spring 151 supports the straight plate 121. Rotating the first threaded rod 152 causes the first threaded rod 152 to push the straight plate 121 to slide. During the sliding process of the straight plate 121, the push plate 141 is driven to slide along the first through hole 14, so that the clamping plate 142 clamps the GRC wall panel 3.

[0044] As Figure 2As shown in the figure, a pair of jacks 17 are provided on the side wall of the mounting plate 1 away from the mounting groove 11; a pair of insertion plates 21 that can be inserted into the jacks 17 are fixedly connected to the side of the keel frame 2 close to the mounting plate 1; engaging holes 211 are provided on the side walls of the pair of insertion plates 21 away from each other; second through holes 18 communicating with the pair of jacks 17 respectively are provided on the end faces of the pair of first cavities 12 close to each other, and a fixing member 16 is provided on the side wall of the straight plate 121 close to the push plate 141; the fixing member 16 includes a clamping block 161 that can cooperate with the engaging hole 211; the clamping block 161 is fixedly connected to the side wall of the straight plate 121 close to the push plate 141, and the clamping block 161 is slidably engaged with the inner side wall of the second through hole 18.

[0045] During the sliding process of the straight plate 121, the straight plate 121 pushes the clamping block 161 to slide along the second through hole 18, so that the clamping block 161 is embedded into the engaging hole 211 on the side wall of the insertion plate 21, thereby realizing the connection between the mounting plate 1 and the keel frame 2, and further realizing the installation of the GRC wall panel 3 on the keel frame 2. The installation method is simple and convenient, avoiding the trouble of using multiple screws and nuts to connect the GRC wall panel 3 and the keel frame 2.

[0046] As Figure 3 and Figure 4 shown, the combined GRC wall panel, based on the above GRC curtain wall, includes a plurality of panels 4 spliced with each other and fixing blocks 5 connecting adjacent panels 4; placing grooves 41 are provided on the side walls of adjacent panels 4 in contact with each other; the fixing blocks 5 are installed in the placing grooves 41 where adjacent panels 4 are in contact with each other; when combining and connecting the panels 4, the fixing blocks 5 are placed in the placing grooves 41 where adjacent panels 4 cooperate with each other, and the adjacent two panels 4 are fixedly connected by the fixing blocks 5.

[0047] As Figure 4 and Figure 5 shown, a second cavity 51 is provided inside the fixing block 5; fixing holes 42 are provided on the inner side wall of the bottom end of the placing groove 41; a pair of third through holes 52 cooperating with the fixing holes 42 are provided on the inner side wall of the bottom end of the second cavity 51; the pair of third through holes 52 correspond to the positions of the fixing holes 42 in the pair of mating placing grooves 41 one by one, a pair of insertion blocks 521 that can be embedded into the fixing holes 42 are slidably connected in the pair of third through holes 52, and limiting grooves 53 are provided on the inner side walls of the pair of third through holes 52 away from each other; limiting plates 522 are fixedly connected to the side walls of the pair of insertion blocks 521 away from each other; the limiting plates 522 are slidably engaged with the inner side walls of the limiting grooves 53, and a second spring 523 is fixedly connected to the bottom surface of the limiting plates 522; the end of the second spring 523 away from the limiting plate 522 is fixedly connected to the inner side wall of the bottom end of the limiting groove 53; a driving mechanism 6 for driving the pair of insertion blocks 521 to be embedded into the fixing holes 42 is provided in the second cavity 51.

[0048] After the fixed block 5 is placed in the placement groove 41, the driving mechanism 6 is used to push the insertion block 521 to slide along the third through hole 52, so that the insertion block 521 is embedded in the fixing hole 42 to realize the fixed connection between adjacent panels 4; during the sliding process of the insertion block 521, the limiting plate 522 slides along the limiting groove 53. The cooperation between the limiting plate 522 and the limiting groove 53 makes it difficult for the insertion block 521 to extend excessively outside the second through hole 18, which is convenient for the driving mechanism 6 to push the insertion block 521 to slide. The setting of the second spring 523 facilitates the return sliding of the insertion block 521.

[0049] As Figure 5 shown, a first inclined surface 524 is provided on the top surface of a pair of insertion blocks 521; the driving mechanism 6 includes a pair of sliders 61 and an extrusion assembly 63; the pair of sliders 61 are slidably connected inside the second cavity 51, and a first rounded corner 611 that cooperates with the first inclined surface 524 is provided on the bottom surface of the pair of sliders 61. Third springs 62 are fixedly connected to the side walls of the pair of sliders 61 facing away from each other, and the end surfaces of the third springs 62 away from the sliders 61 are fixedly connected to the inner side wall of the second cavity 51. The extrusion assembly 63 is arranged inside the second cavity 51, and the extrusion assembly 63 can push the pair of sliders 61 to respectively extrude the pair of insertion blocks 521.

[0050] By pushing the pair of sliders 61 to slide in a direction away from each other through the extrusion assembly 63, during the sliding process of the slider 61, the first rounded corner 611 contacts the first inclined surface 524. Under the cooperation of the first rounded corner 611 and the first inclined surface 524, the slider 61 extrudes the insertion block 521 to slide down to achieve the fixing effect.

[0051] As Figure 5 and Figure 6 shown, a second inclined surface 612 is provided on the side walls of the pair of sliders 61 facing each other; a second threaded hole 511 is provided on the inner side wall at the top end of the second cavity 51; the extrusion assembly 63 includes a pressing plate 631, a fourth spring 632 and a second threaded rod 634; the pressing plate 631 is slidably connected to the inner side wall of the second cavity 51; a second rounded corner 633 that cooperates with the second inclined surface 612 is provided on the side wall of the pressing plate 631 close to the second inclined surface 612. One end of the fourth spring 632 is fixedly connected to the bottom surface of the pressing plate 631; the end of the fourth spring 632 away from the pressing plate 631 is fixedly connected to the inner side wall at the bottom end of the second cavity 51; the second threaded rod 634 is threadedly connected in the second threaded hole 511; the bottom end of the second threaded rod 634 contacts the top surface of the pressing plate 631.

[0052] By rotating the second threaded rod 634, the second threaded rod 634 is used to push the pressing plate 631 to slide. Under the cooperation of the second rounded corner 633 and the second inclined surface 612, the pressing plate 631 pushes the pair of sliders 61 to slide in a direction away from each other. The fourth spring 632 provided at the bottom of the pressing plate 631 can drive the pressing plate 631 to return when the pressing plate 631 is not under the extrusion force of the second threaded rod 634.

[0053] As Figure 5 and Figure 6 shown, at the position corresponding to the second threaded hole 511 on the top surface of the fixed block 5, a counterbore 54 is provided; the counterbore 54 and the second threaded hole 511 are coaxial. A pair of guide rods 635 are fixedly connected to the inner side wall of the bottom end of the second cavity 51. The top ends of the pair of guide rods 635 penetrate through the pressure plate 631 and extend to contact the inner side wall of the top end of the second cavity 51. The pressure plate 631 is in sliding fit with the outer side wall of the guide rods 635.

[0054] The setting of the counterbore 54 facilitates the fixed block 5 to accommodate the larger head of the second threaded rod 634, which is convenient for the installation of the GRC wall panel 3. The guide rods 635 play a limiting role on the pressure plate 631 during the sliding process of the pressure plate 631, so that the pressure plate 631 is not easily displaced.

[0055] As Figure 4 shown, the GRC panel, based on the above-mentioned combined GRC wall panel, includes a panel 4; a sound insulation layer 43 is provided inside the panel 4, and the material of the sound insulation layer 43 is a polyester fiber board; the sound insulation layer 43 provided inside the panel 4 enables the panel 4 to have good sound insulation effect after overall assembly, reducing the possibility of external environmental noise being transmitted to the interior of the building.

[0056] Working principle: First, assemble the panel 4. Place the fixing block 5 in the placement groove 41 on the side wall of the mutually spliced panel 4. At this time, the third through hole 52 at the bottom of the fixing block 5 is aligned with the fixing hole 42 in the placement groove 41. In the initial state, the bottom of the plug 521 is located inside the third through hole 52. Rotate the second threaded rod 634, and the second threaded rod 634 pushes the pressure plate 631 to slide down along the guide rod 635 and compress the fourth spring 632. During the sliding process of the pressure plate 631, the second fillet 633 contacts the second inclined surface 612. Through the cooperation of the second fillet 633 and the second inclined surface 612, the pressure plate 631 pushes a pair of sliders 61 to slide in opposite directions. During the sliding process of the sliders 61, the first fillet 611 on the sliders 61 contacts the first inclined surface 524 on the plug 521. Under the cooperation of the first fillet 611 and the first inclined surface 524, the plug 521 slides down along the second through hole 18 and is inserted into the fixing hole 42, thereby realizing the connection of adjacent panels 4. The settings of the third spring 62 and the second spring 523 facilitate the return sliding of the sliders 61 and the plug 521, which is convenient for realizing the disassembly of adjacent panels 4. The limiting plate 522 limits the height of the plug 521 extending into the second cavity 51, so that the plug 521 is not likely to extend excessively into the second cavity 51, in order to realize the extrusion of the plug 521 by the sliders 61. After the panel 4 is spliced, multiple panels 4 form the GRC wall panel 3. Then, install the GRC wall panel 3 into the installation groove 11 on the side wall of the installation plate 1. The installation plate 1 supports the GRC wall panel 3. Align the jack 17 on the side wall of the installation plate 1 with the plug plate 21 on the side wall of the keel frame 2, so that the plug plate 21 is inserted into the jack 17. Then rotate the first threaded rod 152 so that the end of the first threaded rod 152 presses the straight plate 121 and stretches the first spring 151. During the sliding process of the straight plate 121, the straight plate 121 pushes the push plate 141 and the clamping block 161 to slide along the first through hole 14 and the second through hole 18 respectively. The push plate 141 pushes the clamping plate 142 to slide towards the GRC wall panel 3, so that the clamping plate 142 clamps the side wall of the GRC wall panel 3, improving the stability of the GRC wall panel 3 in the installation groove 11. The clamping block 161 is inserted into the locking hole 211 of the plug plate 21 under the pushing action of the straight plate 121, realizing the fixation between the installation plate 1 and the keel frame 2, and further realizing the installation of the GRC wall panel 3 on the keel frame 2, avoiding the trouble of connecting the GRC wall panel 3 and the keel frame 2 with screws and nuts, and reducing the possibility of the GRC wall panel 3 falling off the keel frame 2.

[0057] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
