Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated walls, and in particular to a quick-install prefabricated wall. Background Art

[0002] Prefabricated walls are wall components prefabricated in a factory. They have the advantages of environmentally friendly materials, low on-site labor, and high construction quality. There are many types of prefabricated walls, including prefabricated concrete wall panels, ALC wall panels, GRC wall panels, fiber cement wall panels, and lightweight brick block wall panels. Among them, ALC wall panels are lightweight prefabricated wall panels made from cement, sand, lime, aluminum powder, etc. as the main raw materials, through batching, mixing, foaming, autoclaving and other processes. They are mainly used for partitions inside houses and have the advantages of thermal insulation, convenient construction and green environmental protection.

[0003] When installing ALC wall panels, they need to be supported between the ceiling and the floor to form a partition for the house. The length of the ALC wall panels is shorter than the distance between the ceiling and the floor, so that the ALC wall is converted from a flat state to a vertical state. This results in a gap between the top of the ALC wall panels and the ceiling after the ALC wall panels are vertically erected. Workers need to use ladders and construction frames to inject glue into the gap to achieve a complete partition of the house. This method not only leads to a high degree of danger for workers in the construction, but also affects the installation efficiency of the ALC wall panels. Summary of the Invention

[0004] In order to overcome the shortcomings mentioned in the above background technology, the present invention provides a quick-install prefabricated wall.

[0005] Technical solution: A quick-install prefabricated wall, including a prefabricated wall panel, a steel reinforcement member is arranged in the prefabricated wall panel, and also includes a support shell, the support shell is arranged in the prefabricated wall panel, two support shafts are slidably connected in the support shell, a trigger assembly is arranged in the support shell, the trigger assembly is used to drive the two support shafts to slide outward along the support shell, raising the height of the prefabricated wall panel, the prefabricated wall panel is provided with two one-way limit assemblies, the one-way limit assembly is used to lock the support shaft in one direction, so that the support shaft slides in one direction along the support shell.

[0006] As an improvement to the above solution, protrusions and grooves are respectively provided on both sides of the prefabricated wall panels to facilitate the positioning and splicing of the prefabricated wall panels.

[0007] As an improvement to the above solution, the bottom of the support shaft is a frustum structure, which is used to improve the supporting strength of the prefabricated wall panel.

[0008] As an improvement to the above solution, the trigger component includes two push shafts. Both of the two push shafts are slidably connected to the support shell. The two push shafts are commonly and fixedly connected to a trigger plate. The push shaft is fixedly connected to a pressing block. The support shaft is fixedly connected to a pressed block. Two transmission components are arranged in the support shell. The transmission components are used to drive the adjacent support shaft and the adjacent push shaft to move in opposite directions.

[0009] As an improvement to the above solution, the trigger plate is provided with symmetrically distributed inclined surfaces, which facilitate the trigger plate to slide along the support shell under force.

[0010] As an improvement to the above solution, the transmission component includes a first connection block. The first connection block is slidably connected in the support shell. The first connection block is used to press the adjacent pressed block. A second connection block is slidably connected in the support shell. The pressing block is used to press the adjacent second connection block. A connecting rod is commonly arranged between the first connection block and the second connection block.

[0011] As an improvement to the above solution, the one-way limiting component includes a clamping shaft. The clamping shaft is fixedly connected to the precast wall panel. The support shaft is provided with a clamping plate. A first elastic element is fixedly connected between the support shell and the clamping plate. The support shaft penetrates through the clamping plate. The clamping shaft limits one end of the clamping plate, making the clamping plate inclined to limit the support shaft.

[0012] As an improvement to the above solution, the precast wall panel is provided with a notch. The trigger plate is located in the notch. The steel bar reinforcement is misaligned with the notch of the precast wall.

[0013] As an improvement to the above solution, a bolt is slidably connected to the trigger plate. The precast wall panel is provided with a first limiting hole and a second limiting hole. The bolt limits the trigger plate through the first limiting hole and the second limiting hole.

[0014] As an improvement to the above solution, both the first connection block and the second connection block are slidably connected to the connecting rod. A second elastic element is arranged between the first connection block and the second connection block.

[0015] The present invention has the following advantages: 1. In the present invention, two support shafts protrude from the precast wall panel and lift and support the precast wall panel, filling the gap between the precast wall panel and the ceiling, making the top of the precast wall panel fit with the ceiling, and uniformly transferring the gap to the bottom of the precast wall panel for glue injection treatment, simplifying the construction process, and improving the construction safety level and installation rate.

[0016] 2. By inserting the pin into the first limiting hole, the trigger plate is exposed to the notch at the bottom of the prefabricated wall panel, which can cope with the laying of pipes and lines through the wall and improve the laying efficiency.

[0017] 3. When the support shaft cannot continue to move, the second connecting block slides along the connecting rod, and the second elastic member is compressed to offset the sliding distance of the trigger plate, so that the two support shafts adapt to the height difference of the floor, thereby improving the installation stability of the prefabricated wall.

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] During the installation process of ALC wall panels, they usually need to be erected between the ceiling and the ground to effectively separate the space. To facilitate quick installation, the actual length of the ALC wall panels is generally slightly shorter than the clear height between the ceiling and the ground. In this way, they can be placed flat in place during installation and then flipped and lifted to a vertical state.

[0028] Due to this installation method, when the ALC wall panels are straightened, a certain gap is often formed between their top and the ceiling. To ensure the wall has good sealing and structural integrity, construction workers need to use auxiliary equipment such as ladders or scaffolding to inject sealant into the gap. This construction method not only increases the operating risks of workers, but also reduces the installation efficiency of ALC wall panels.

[0029] During installation, ALC wall panels need to be placed between the ceiling and the floor to achieve their partitioning function. However, because the length of the ALC wall panels is shorter than the distance between the ceiling and the floor, they must first be adjusted from a horizontal to a vertical position during installation. This adjustment leaves a gap between the top of the ALC wall panel and the ceiling. To ensure a complete partitioning of the house, construction workers need to use auxiliary equipment such as ladders or scaffolding to inject sealant into this gap. This construction method not only increases the operational risks for workers but also reduces the efficiency of ALC wall panel installation.

[0030] Example 1

[0031] This embodiment discloses a quick-assembly prefabricated wall, which is used for quickly splicing to form partitions and increasing the aesthetics of the splicing.

[0032] A quick-install prefabricated wall, such as Figures 1-4 As shown, it includes a prefabricated wall panel 1, a steel reinforcement 2 is arranged in the prefabricated wall panel 1, the steel reinforcement 2 is made of carbon steel, which is low in cost, and the shape of the steel reinforcement 2 is formed by bundling a plurality of straight steel bars and a plurality of rectangular steel bars, which improves the structural strength of the prefabricated wall panel 1, a support shell 3 is arranged in the prefabricated wall panel 1, the support shell 3 is located at the bottom of the prefabricated wall panel 1, and two support shafts 4 are slidably connected in the support shell 3. In the initial state, the bottoms of the two support shafts 4 are flush with the bottom of the prefabricated wall panel 1, and a trigger component is arranged in the support shell 3. The component is used to drive the two support shafts 4 to slide outward along the support shell 3 to raise the height of the prefabricated wall panel 1. The prefabricated wall panel 1 is provided with two one-way limit components. The one-way limit components are used to lock the support shaft 4 in one direction so that the support shaft 4 can slide in one direction along the support shell 3. A protrusion and a groove are respectively provided on both sides of the prefabricated wall panel 1. The protrusion is located on the left side of the prefabricated wall panel 1, and the groove is located on the right side of the prefabricated wall panel 1, forming a simple mortise and tenon structure, which is convenient for the positioning and splicing of the prefabricated wall panel 1. The bottom of the support shaft 4 is a frustum structure, which is used to improve the supporting strength of the prefabricated wall panel 1.

[0033] The above arrangement enables the two support shafts 4 to protrude from the prefabricated wall panel 1 in one direction, thereby supporting and lifting the prefabricated wall panel 1, so that the top of the prefabricated wall panel 1 fits with the ceiling, forming a seamless fit between the prefabricated wall panel 1 and the ceiling, thereby improving the aesthetics.

[0034] like Figures 1-6 As shown, the trigger assembly includes two push shafts 201, and the two push shafts 201 are slidably connected to the support shell 3. The two push shafts 201 are located in the middle of the support shell 3, and the two support shafts 4 are located on both sides of the two push shafts 201. The two push shafts 201 are fixedly connected to a trigger plate 202. The lower side of the trigger plate 202 is flush with the lower side of the prefabricated wall panel 1. The push shaft 201 is fixedly connected to an extrusion block 203, and the support shaft 4 is fixedly connected to a pressure block 204. The extrusion block 203 and the pressure block 204 are both trapezoidal blocks. The upper bottoms of the extrusion block 203 and the pressure block 204 are located on the upper side, and the lower bottoms are located on the lower side. Two transmission assemblies are provided in the support shell 3. The transmission assemblies are used to drive adjacent support shafts 4 and adjacent push shafts 201 to move in opposite directions. The trigger plate 202 is provided with symmetrically distributed inclined surfaces for easy The staff uses a crowbar to pry the trigger plate 202, so that the trigger plate 202 is forced to slide along the support shell 3. The transmission assembly includes a first connecting block 205, which is slidably connected to the support shell 3. The first connecting block 205 is used to squeeze the adjacent pressure block 204. The second connecting block 206 is slidably connected to the support shell 3. The first connecting block 205 and the second connecting block 206 are both right-angled triangle blocks, and the hypotenuse of the first connecting block 205 fits with the waist of the pressure block 204, and the hypotenuse of the second connecting block 206 fits with the waist of the extrusion block 203. The extrusion block 203 is used to squeeze the adjacent second connecting block 206. The first connecting block 205 and the second connecting block 206 are jointly provided with a connecting rod 207, and the connecting rod 207 is located between the first connecting block 205 and the second connecting block 206.

[0035] The above arrangement can be realized. When the staff pries the trigger plate 202 with a crowbar, the trigger plate 202 drives the squeezing block 203 to move upward through the push shaft 201, so that the waist of the squeezing block 203 pushes the oblique edge of the second connecting block 206. The second connecting block 206 is forced to drive the first connecting block 205 to slide horizontally through the connecting rod 207. The oblique edge of the first connecting block 205 squeezes the waist of the pressure block 204, so that the pressure block 204 drives the support shaft 4 thereon to move downward.

[0036] like Figure 3As shown, the one-way limit assembly includes a card shaft 301, which is fixedly connected to the bottom of the prefabricated wall panel 1. The card shaft 301 is located on one side of the corresponding support shaft 4. The support shaft 4 is provided with a card plate 303. A first elastic element 302 is fixedly connected between the support shell 3 and the card plate 303. The first elastic element 302 is a tension spring and is initially in a stretched state, which is used to apply an upward force to the card plate 303. The support shaft 4 passes through the card plate 303, and the card shaft 301 limits one end of the card plate 303, so that the card plate 303 is tilted to limit the support shaft 4.

[0037] The above setting can be achieved. When the support shaft 4 is subjected to a downward force, the card plate 303 is subjected to the downward force and is gradually corrected to a parallel state, thereby realizing the downward movement of the support shaft 4. However, when the support shaft 4 is subjected to an upward force, the support shaft 4 applies an upward force to the card plate 303. At this time, the card shaft 301 limits one end of the card plate 303, and the card plate 303 generates an extrusion force on the support shaft 4, so that the support shaft 4 generates a normal force at the position where it contacts the card plate 303. The friction between the support shaft and the card plate 303 increases, so that the card plate 303 forms a stuck limit on the support shaft 4, thereby realizing the state that the support shaft 4 can only slide downward.

[0038] When the prefabricated wall needs to be installed, the staff will move the prefabricated wall to the required installation position, then change the prefabricated wall from a flat state to a vertical state, and apply glue on the side of the prefabricated wall. Then the staff will move the prefabricated wall panel 1 with a crowbar, so that the prefabricated wall panel 1 will gradually move to the installation position, so that the protrusion of the prefabricated wall panel 1 will be docked with the groove of the corresponding prefabricated wall panel 1, and the position of the prefabricated wall panel 1 will be gradually corrected with the crowbar until the position of the prefabricated wall panel 1 coincides with the installation position. At this time, the preliminary installation work of the prefabricated wall is completed.

[0039] When the prefabricated wall is initially installed, the staff uses a crowbar to pry the trigger plate 202, so that the trigger plate 202 is driven by the prying force to drive the two push shafts 201 to slide upward along the support shell 3, so that the two push shafts 201 drive the extrusion block 203 thereon to slide upward. At this time, the extrusion block 203 pushes the pressure block 204 through the adjacent first connecting block 205, the connecting rod 207 and the second connecting block 206, so that the pressure block 204 drives the adjacent support shaft 4 to slide downward, and the support shaft 4 moves downward in contact with the adjacent card plate 303. Since the card plate 303 is in the position under the action of the card shaft 301 and the first elastic element 302, In the tilted state, the support shaft 4 can slide downward along the card plate 303, but cannot slide upward along the card plate 303. The two support shafts 4 gradually extend out of the support shell 3 and gradually lift the prefabricated wall panel 1 under the action of the floor, so that the top of the prefabricated wall panel 1 contacts the ceiling. The two support shafts 4 cannot extend out. The prefabricated wall panel 1 is extended through the two support shafts 4. The two support shafts 4 lift and support the prefabricated wall panel 1 so that the top of the prefabricated wall panel 1 fits the ceiling. The two support shafts 4 make up for the gap between the prefabricated wall panel 1 and the ceiling, reduce the existence of obvious gaps between the prefabricated wall panel 1 and the ceiling, and simplify the construction process.

[0040] When the prefabricated wall panel 1 is fitted with the ceiling, the staff stops prying the trigger plate 202. At this time, the trigger plate 202 slides downward due to gravity, and the trigger plate 202 drives the two push shafts 201 to reset, releasing the squeezing of the squeezing block 203 on the second connecting block 206. When the trigger plate 202 is reset to its initial position, the installation of the prefabricated wall is completed. At this time, since the top of the prefabricated wall panel 1 is fitted with the ceiling, the gap between the bottom of the prefabricated wall panel 1 and the floor is increased. Then the staff injects colloid into the gap between the bottom of the prefabricated wall panel 1 and the floor. In subsequent decoration, the gap between the bottom of the prefabricated wall panel 1 and the floor will be blocked by the laying of the floor. When the prefabricated wall needs to be spliced and installed again, the above steps are repeated.

[0041] Example 2

[0042] This embodiment discloses a quick-install prefabricated wall, which is a further improvement on the basis of the first embodiment.

[0043] like Figure 5 and Figure 6As shown, a notch is provided at the bottom of the precast wall panel 1. The trigger plate 202 is located within the notch. The notch at the bottom of the precast wall panel 1 provides a sliding area for the trigger plate 202. At the same time, the notch can be used for the laying of pipes and lines through the wall. The steel reinforcement member 2 is misaligned with the notch of the precast wall. The trigger plate 202 is in a "U" shape and is slidably connected to the precast wall panel 1, and is used to control the opening and closing of the notch of the precast wall panel 1. When the lower side surface of the trigger plate 202 is flush with the lower side surface of the precast wall panel 1, the trigger plate 202 blocks the notch. A through hole is provided on the trigger plate 202, and the bolt 401 slides within the through hole of the trigger plate 202. The trigger plate 202 is slidably connected with a bolt 401 through the through hole thereon. The precast wall panel 1 is provided with a first limit hole 402 and a second limit hole 403. The bolt 401 limits the trigger plate 202 through the first limit hole 402 and the second limit hole 403. In the initial state, the through hole on the trigger plate 202 is aligned with the second limit hole 403, and the bolt 401 is inserted into the second limit hole 403. At this time, the trigger plate 202 blocks the notch, and the probability of accidental touch of the trigger plate 202 is reduced. When the through hole on the trigger plate 202 is aligned with the first limit hole 402 (the trigger plate 202 can be pried to the highest position), the bolt 401 is inserted into the first limit hole 402, exposing the notch at the bottom of the precast wall panel 1 for the laying of pipes and lines.

[0044] The above settings can achieve that after the staff pries the trigger plate 202 with a crowbar, the trigger plate 202 slides along the precast wall panel 1. The staff determines whether the precast wall panel 1 needs the laying of pipes through the wall, and then by manipulating the bolt 401 to insert into the first limit hole 402 and the second limit hole 403, the trigger plate 202 is used to expose and block the notch at the bottom of the precast wall panel 1.

[0045] Before the installation of this precast wall, according to the actual situation, holes need to be cut at the bottom of some precast wall panels 1 for the subsequent laying of pipes and lines through the wall. After this precast wall is moved to the installation position, the staff pulls out the bolt 401. The bolt 401 slides out along the second limit hole 403 and the trigger plate 202, releasing the limit of the trigger plate 202. Then the staff starts to pry the trigger plate 202 to lift this precast wall. When the lifting of the precast wall is completed, at this time, the through hole on the trigger plate 202 is aligned with the first limit hole 402. When the laying of pipes and lines through the wall is required for this precast wall, the staff manipulates the bolt 401 to insert into the through hole on the trigger plate 202 and the first limit hole 402, so that the bolt 401 limits and locks the trigger plate 202, exposing the notch at the bottom of the precast wall panel 1 for the laying of pipes and lines. Then the staff stops prying the trigger plate 202.

[0046] When the prefabricated wall does not need to be penetrated by pipes and lines, the staff directly stops prying the trigger plate 202, so that the trigger plate 202 is reset to its initial state under gravity, and the trigger plate 202 covers the notch. Then the staff inserts the pin 401 into the second limiting hole 403 through the trigger plate 202, and the installation of the prefabricated wall is completed at this time.

[0047] Example 3

[0048] This embodiment discloses a quick-install prefabricated wall, which is a further improvement on the basis of the second embodiment.

[0049] like Figure 4 and Figure 7 As shown, the first connecting block 205 and the second connecting block 206 are both slidably connected to the connecting rod 207. In other embodiments, the relationship between the first connecting block 205 and the second connecting block 206 and the connecting rod 207 is a fixed connection. A second elastic member 501 is provided between the first connecting block 205 and the second connecting block 206. The second elastic member 501 is a spring, which is used to enable the first connecting block 205 and the second connecting block 206 to slide along the connecting rod 207.

[0050] The above setting can be achieved that when the first connecting block 205 cannot push the corresponding support shaft 4 to slide outward, the second connecting block 206 can slide along the connecting rod 207, and the second elastic member 501 is compressed, thereby causing the other support shaft 4 to continue to slide outward until it cannot slide, so that the two support shafts 4 can adapt to the height difference of the floor.

[0051] When the two support shafts 4 are squeezed and extended along the prefabricated wall panel 1, the floor may be uneven during the pouring process, that is, there is a height difference between the ground contacted by the two support shafts 4, which will cause the installation of the prefabricated wall to be unstable. Therefore, when the trigger plate 202 drives the two push shafts 201 to move upward, the squeezing block 203 squeezes the adjacent second connecting block 206, so that the second connecting block 206 drives the first connecting block 205 to move synchronously through the connecting rod 207 and the second elastic member 501. The first connecting block 205 squeezes the compressed block 204, so that the compressed block 204 drives the adjacent support shaft 4 to slide downward. When one of the support shafts 4 cannot continue to move downward, the staff continues to pry the trigger plate 202. Since the support shaft 4 cannot continue to move downward, the staff continues to pry the trigger plate 202. At this time, the second connecting block 206 is pressed and slides along the connecting rod 207, and the second elastic member 501 is compressed until the other support shaft 4 can no longer move downward. Then the staff continues to pry the trigger plate 202 to align the through hole on the trigger plate 202 with the first limit hole 402. At this time, the staff repeats the steps of Example 2, and determines the position of the trigger plate 202 according to actual conditions, whether the prefabricated wall needs to be laid through the wall for pipes, and then locks the trigger plate 202. When the support shaft 4 can no longer move, the second connecting block 206 slides along the connecting rod 207, and the second elastic member 501 is compressed to offset the sliding distance of the trigger plate 202, so that the two support shafts 4 adapt to the height difference of the floor, thereby improving the installation stability of the prefabricated wall.

[0052] The above is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
