Description

Technical Field

[0001] The present application relates to the field of building construction technology, and in particular to a lightweight all-aluminum prefabricated formwork structure and a modular construction method thereof. Background Art

[0002] Prefabricated formwork structures have a wide range of application scenarios in the field of construction engineering, especially in projects that require high precision, rapid construction and reuse of formwork, such as prefabricated buildings, bridges, dams, hydropower stations and other fields. The use of prefabricated formwork construction has the advantages of shortening construction period, reducing construction risks, improving construction quality and reducing construction costs.

[0003] At present, the prefabricated formwork structure mainly includes an outer formwork and an inner membrane formed by splicing multiple formworks in sequence, and a diagonal brace bracket for supporting the formwork; the inner formwork and the outer formwork are the key parts of the building frame wall, wherein the inner formwork and the outer formwork are set at intervals, and when the inner formwork and the outer formwork are precisely spliced ​​and built, a continuous closed space will be formed, and then the inner formwork and the outer formwork need to be fixed and positioned by the diagonal brace bracket after the splicing is completed, to ensure that the formwork is not easily displaced or deformed during the concrete pouring process; after the space between the inner formwork and the outer formwork is prepared, concrete pouring begins, and the pouring of concrete needs to be carried out in a certain order and speed to avoid excessive pressure on the formwork structure, while ensuring the concrete Density and uniformity; after the concrete is poured, it needs to be cured to ensure that the concrete reaches sufficient strength before the formwork can be removed. The order of removing the formwork is usually the opposite of the installation order. The outer formwork is removed first, and then the inner formwork is removed to avoid damage to the concrete structure. The removed formwork is cleaned and inspected and can be used for the next construction project; however, when the outer formwork and the inner formwork are spliced ​​together through the formwork, a large number of bolts are required to splice adjacent formworks. Not only is the disassembly and assembly cumbersome, it also requires a lot of labor intensity and time, resulting in low overall construction efficiency, and the bolt connection is susceptible to vibration or the degree of tightness of the tightening, resulting in the risk of local bolts loosening and falling off. Summary of the invention

[0004] In order to increase the disassembly and assembly speed of adjacent formworks, shorten the construction period, and at the same time improve the stability of the connection between adjacent formworks, the present application provides a lightweight all-aluminum prefabricated formwork structure and a modular construction method thereof.

[0005] The present application provides a lightweight all-aluminum prefabricated formwork structure and a modular construction method thereof, which adopts the following technical solutions: In a first aspect, a lightweight all-aluminum prefabricated formwork structure includes an inner mold and an outer mold formed by sequentially splicing a plurality of formworks, and a diagonal support bracket arranged on one side of the formwork, wherein the inner mold and the outer mold are arranged at intervals, and a casting chamber is formed between the inner mold and the outer mold; A connecting rod is slidably connected to one side of the template, and a plurality of connecting rods are provided. The connecting rods are arranged obliquely, and a plurality of connecting blocks corresponding to the connecting rods are fixedly provided on the side of the template away from the connecting rods. The connecting rods can be plugged into corresponding connecting blocks on adjacent templates; The tensioning quick-connect mechanism is arranged on the template and is used to drive the connecting rod to be inserted and fixed into the corresponding connecting block on the adjacent template, and at the same time apply tensioning force to the joint of two adjacent templates.

[0006] By adopting the above technical solution, when carrying out construction, firstly align and arrange the adjacent templates in sequence according to the design requirements, then arrange the inner and outer templates at intervals according to the design requirements, and then drive the connecting rod to be inserted and fixed into the connecting block through the tensioning quick-connect mechanism between the two adjacent templates, and at the same time apply tensioning force to the joints of the two adjacent templates to ensure that the templates are tightly connected; after the templates are spliced, a closed pouring chamber is formed, and then concrete is poured according to the construction specifications, and the density and uniformity of the concrete are ensured during the pouring process; after the concrete reaches the designed strength, it is cured, and after the concrete wall panel reaches sufficient strength, the template can be removed, first the outer template and then the inner template, so as to avoid damage to the concrete structure; on the one hand, the connecting rod and the tensioning quick-connect mechanism are used to connect the templates, and then the outer template and the inner template are removed. The use of the connecting mechanism and the like makes it unnecessary to install and remove a large number of bolts during the entire installation and disassembly process of the inner and outer molds, thereby simplifying the splicing and disassembly process of the templates, significantly reducing the time of template splicing, and improving the construction speed. On the other hand, the tensioning quick-connect mechanism applies tensioning tension to the template joints, so that the template is not easily displaced or deformed during the concrete pouring process, thereby preventing defects such as gaps from forming, improving the sealing of the structure, ensuring that the structure dimensions are accurate and the surface is flat after the concrete is poured, reducing the subsequent finishing work, and improving the overall quality of the construction project; at the same time, the inclined setting of the connecting rod disperses the horizontal tension between the two adjacent templates to other directions, thereby enhancing the compressive strength of the template during the concrete pouring process, and further preventing gaps from forming between the two adjacent templates under the huge pressure of pouring concrete.

[0007] Optionally, the tensioning quick-connect mechanism includes: A driving assembly is disposed between the plurality of connecting rods and is used to drive the plurality of connecting rods to move synchronously and lock the positions of the connecting rods after they move; A tensioning assembly is provided between the connecting rod and the template, and is used to apply a certain tensioning force between two adjacent templates through the connecting rod; The fixing assembly is arranged between the connecting rod and the connecting block, and is used for connecting and fixing the connecting rod and the connecting block.

[0008] By adopting the above technical solution, during the template splicing process, the driving component is first started, and the driving component synchronously drives all the connecting rods to move, and then the connecting rods begin to move toward the connecting block on one side of the adjacent template. At this time, the tensioning component starts to work, and as the connecting rods gradually move toward the inside of the connecting block, the tensioning force applied by the connecting rods to the two adjacent templates gradually increases until they are fully inserted into the connecting block; wherein, through the coordinated use of the driving component, the tensioning component, and the fixing component, the connecting rods are tightly connected between the two adjacent templates, and the tensioning force is continuously applied to the template splicing, so that the template is not easily displaced or deformed during the concrete pouring process, ensuring that the structural dimensions after concrete pouring are accurate and the surface is flat, reducing the later finishing work, and improving the overall quality of the construction project.

[0009] Optionally, the driving component includes: The driving rack is fixedly arranged at the middle part of the connecting rod; A rotating shaft is rotatably connected to the template, and a plurality of rotating shafts are provided and correspond one to one with the plurality of connecting rods; A driving gear is fixedly sleeved on the rotating shaft, and the driving gear is meshed with a corresponding driving rack; Wherein, a sprocket is provided on the outer fixed sleeve of the rotating shaft, and chains are meshed on the outer sides of two adjacent sprockets; and further comprising: The one-way locking component is arranged between one of the rotating shafts and the template, and is used to lock the angle of the rotating shaft after rotation.

[0010] By adopting the above technical solution, when multiple connecting rods are synchronously driven to move by the driving assembly, the construction personnel first rotate one of the rotating shafts, and the rotating shaft synchronously drives multiple driving gears to rotate through the linkage of the sprocket and the chain, and the driving gear can drive the connecting rod fixedly connected to it to move toward the connecting block on the adjacent template; when the connecting rod is moved to be fully inserted into the connecting block, the rotating shaft rotates to a predetermined angle, and the one-way locking component locks the position of the rotating shaft to prevent it from rotating in the opposite direction, thereby ensuring that the position of the connecting rod is stable during the force application process of the tensioning assembly.

[0011] Optionally, the one-way locking component includes: A locking sleeve is fixed on the outer side of the template; A ratchet wheel, fixedly sleeved on the outer side of the rotating shaft; A locking shaft, rotatably connected to the locking sleeve; A pawl is fixedly sleeved on the outside of the locking shaft and meshes with the ratchet wheel; The torsion spring is arranged between the locking shaft and the locking sleeve, and the torsion spring always gives the pawl a force toward meshing with the ratchet wheel.

[0012] By adopting the above technical solution, when the rotating shaft rotates to a predetermined angle and the pawl engages with the ratchet, the locking sleeve prevents the rotating shaft from rotating in the opposite direction through the locking action of the pawl on the ratchet, thereby locking the position of the rotating shaft, ensuring the stability of the position of the connecting rod after being plugged into the connecting block, and preventing displacement due to external force during the concrete pouring process; when the formwork needs to be disassembled, the pawl and the ratchet are separated by rotating the locking shaft, and the engagement between the pawl and the ratchet is released, so as to unlock the rotating shaft; wherein the one-way locking component ensures the locking of the rotating shaft at a predetermined angle through the engagement of the pawl with the ratchet, preventing the displacement of the connecting rod during the concrete pouring process, and improving the stability and sealing of the formwork connection.

[0013] Optionally, the one-way locking component further includes: The locking rod is slidably inserted into one end of the locking shaft along the length direction of the locking shaft; A fixed frame, fixed to the template; The locking magnet is fixedly sleeved on the locking rod and can be adsorbed to the fixing frame.

[0014] By adopting the above technical solution, when the construction personnel need to release the locking state of the rotating shaft by the one-way locking component, they first rotate the locking rod, the locking rod drives the locking shaft to rotate, the locking shaft drives the pawl to move to the side away from the ratchet, so that the ratchet and the pawl are released from the meshing state. At this time, the construction personnel pull the locking rod to the side close to the fixed frame, the locking rod drives the locking magnet to move, and the locking magnet is adsorbed on the fixed frame, so that the ratchet and the pawl can be kept unlocked for a long time; when the construction personnel need to lock the rotation angle of the rotating shaft, they only need to press the locking rod so that the locking rod drives the locking magnet to separate from the fixed frame, and the pawl can rotate under the action of the torsion spring and resume the meshing state with the ratchet; after the construction personnel need to release the locking state of the rotating shaft, there is no need to twist the locking shaft by hand for a long time, so that the ratchet and the pawl can be released from the meshing state.

[0015] Optionally, the tensioning assembly comprises: A support shaft is arranged at an interval at one end of the connecting rod; A tensioning spring is sleeved on the outside of the supporting shaft; A sliding sleeve is sleeved on the outside of the support shaft, two of which are provided, and the two sliding sleeves are respectively located at the two ends of the tensioning spring; two symmetrically arranged connecting rod groups are also provided between the two sliding sleeves; Each of the connecting rod groups includes two tension connecting rods respectively hinged on two sliding sleeves, and a support seat hinged to the two tension connecting rods at the same end away from the sliding sleeve. The two tension connecting rods in the same connecting rod group are symmetrically arranged; one of the support seats in the two connecting rod groups is fixedly connected to the template, and the other support seat is fixedly connected to the connecting rod.

[0016] By adopting the above technical solution, when the connecting rod begins to move toward and plug into the connecting block on the adjacent formwork, the tensioning assembly begins to activate. At this time, the movement of the connecting rod has not yet generated a force on the tensioning assembly. As the connecting rod is plugged into the connecting block, the movement of the connecting rod drives the support seat fixedly connected thereto to move, and then through the tension link in the connecting rod group, the two sliding sleeves are moved toward the center position of the support shaft to compress the tensioning spring. At this time, the tensioning spring stores energy and generates a tensioning force on the connecting rod until the connecting rod is fully plugged and locked into the connecting block. The tensioning force of the tensioning spring is transmitted to the connecting rod and the formwork through the coordinated use of the sliding sleeve, the tension link, the support seat, etc., so that the position of the connecting rod at the formwork connection is stable, so that the adjacent formwork is not easily displaced due to external force during the concrete pouring process, thereby improving the stability and sealing of the formwork connection until the formwork is disassembled and the compression force of the tensioning spring is released.

[0017] Optionally, the tensioning assembly further includes: A fixed limit block is fixedly arranged at one end of the supporting shaft; The movable limit block is detachably connected to the end of the support shaft away from the fixed limit block.

[0018] By adopting the above technical solution, the setting of the fixed limit block and the movable limit block ensures the stability of the tensioning spring during use, prevents the tensioning spring from detaching from the support shaft during compression or release, and improves the reliability of the tensioning assembly; and when the tensioning spring needs to be replaced due to long-term use or damage, the construction personnel can disassemble the movable limit block, remove the tensioning spring from the support shaft, replace the new tensioning spring, and then reinstall the movable limit block, thereby increasing the service life of the tensioning assembly.

[0019] Optionally, the fixing component includes: A fixed block is slidably connected in the template, and is provided in multiple numbers and corresponds to multiple connecting rods one by one. The connecting rods are provided with multiple fixing grooves along their length direction, and the fixed block can be inserted into the fixing grooves; A movable frame is arranged between the plurality of fixed blocks and is slidably connected to the template; A fixed spring, fixedly arranged between the fixed block and the movable frame; The handle is fixed on the movable frame, and one end of the handle passes through the template and is located outside the template. The template is provided with a movable groove, and the handle can slide in the movable groove.

[0020] By adopting the above technical solution, when the connecting rod is moved to and plugged into the connecting block on the adjacent formwork, the construction personnel push the mobile frame through the handle, so that the mobile frame drives the fixed block to slide along the formwork until the fixed block is plugged into the fixed groove on the connecting rod, thereby fixing the connecting rod; after the fixed block is plugged into the fixed groove, the fixing spring is compressed and continuously applies thrust to the fixed block, so that the fixed block is not easily affected by vibration or other external forces and detached from the fixed groove during the concrete pouring process, thereby improving the stability of the fixing assembly.

[0021] Optionally, a side of the fixing block close to the connecting rod is arranged in an inclined surface.

[0022] By adopting the above technical solution, the inclined surface setting reduces the direct contact area between the fixed block and the connecting rod, reduces the friction, and the inclined surface of the fixed block enables the connecting rod to slide along the inclined surface when the fixed block and the connecting rod are initially in contact, without causing jamming due to direct contact, making the connection process of the connecting rod smoother.

[0023] In a second aspect, the present application also provides a modular construction method for a lightweight all-aluminum prefabricated formwork structure, which is applicable to the above-mentioned lightweight all-aluminum prefabricated formwork structure, and the construction steps are as follows: S1. Level the construction surface to ensure the flatness of the ground and mark the lines; S2. Align adjacent templates in sequence according to design requirements, then space the inner and outer templates according to design requirements, and support the templates with diagonal braces; S3, drive the connecting rod to be inserted and fixed into the connecting block through the tensioning quick-connect mechanism between two adjacent templates, and at the same time apply tensioning force to the joint of two adjacent templates to ensure the tight connection between the templates; S4. Then pour concrete into the closed pouring chamber according to the construction specifications. During the concrete pouring process, ensure the uniformity and density of the concrete to avoid the generation of voids and cracks; S5. After the concrete reaches the designed strength, it will be cured. After the concrete wall panels reach sufficient strength, the formwork can be removed. First, the outer formwork will be removed, and then the inner formwork will be removed to avoid damage to the concrete structure.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: 1. On the one hand, by using the connecting rod, tensioning quick-connect mechanism, etc. in combination, it is not necessary to install and remove a large number of bolts during the entire installation and removal process of the inner and outer molds, which simplifies the splicing and disassembly process of the templates, significantly reduces the time of template splicing, and improves the construction speed. On the other hand, the tensioning quick-connect mechanism applies tensioning tension to the template splicing, so that the template is not easy to be displaced or deformed during the concrete pouring process, resulting in gaps, thereby improving the sealing of the structure, ensuring that the structure size is accurate and the surface is flat after the concrete pouring, reducing the subsequent finishing work, and improving the overall quality of the construction project; at the same time, the inclined setting of the connecting rod disperses the horizontal tension between the two adjacent templates to other directions, thereby enhancing the compressive strength of the template during the concrete pouring process, and further preventing the two adjacent templates from producing gaps under the huge pressure of pouring concrete; 2.

DETAILED DESCRIPTION

[0027] The following is combined with Figure 1-Figure 7 This application is described in further detail.

[0028] The present application embodiment discloses a lightweight all-aluminum prefabricated formwork structure. Figure 1 and Figure 2 The structure of the lightweight all-aluminum prefabricated formwork 1 includes an inner mold 2 and an outer mold 3 formed by splicing a plurality of formworks 1 in sequence, and a diagonal support bracket 4 arranged on one side of the formwork 1, wherein the inner mold 2 and the outer mold 3 are spaced apart, and a closed casting chamber 5 is formed between the inner mold 2 and the outer mold 3, and the cross-section of the formwork 1 can be of various specifications such as "I" shape, "L" shape, etc.

[0029] Reference Figure 3 , a plurality of inclined connecting rods 6 are slidably connected to one side of the template 1. For example, the connecting rods 6 are arranged at a certain angle to the horizontal direction, preferably at an angle of 45°. A plurality of connecting blocks 7 corresponding to the plurality of connecting rods 6 are fixedly arranged on the side of the template 1 away from the connecting rods 6. The connecting rods 6 can be plugged into the corresponding connecting blocks 7 on the adjacent templates 1. A tensioning quick-connect mechanism 8 is provided on the template 1. The tensioning quick-connect mechanism 8 is used to drive the connecting rods 6 to be plugged and fixed into the corresponding connecting blocks 7 on the adjacent templates 1, and at the same time apply tensioning force to the joints of the two adjacent templates 1.

[0030] During construction, adjacent templates 1 are first aligned and arranged in sequence according to design requirements, and then the inner template 2 and the outer template 3 are spaced according to design requirements. Then, the tensioning quick-connect mechanism 8 between two adjacent templates 1 drives the connecting rod 6 to be inserted and fixed into the connecting block 7, and at the same time, tensioning tension is applied to the joints of the two adjacent templates 1 to ensure a tight connection between the templates 1. After the templates 1 are spliced, a closed casting chamber 5 is formed, and then concrete is cast according to the construction specifications, and the density and uniformity of the concrete are ensured during the casting process.

[0031] After the concrete reaches the designed strength, it is cured. After the concrete wall panel reaches sufficient strength, the formwork 1 can be removed, first the outer formwork 3, and then the inner formwork 2 to avoid damage to the concrete structure. On the one hand, by using the connecting rod 6, the tensioning quick-connect mechanism 8, etc., there is no need to install and remove a large number of bolts during the entire installation and removal process of the inner formwork 2 and the outer formwork 3, which simplifies the splicing and disassembly process of the formwork 1, significantly reduces the time of splicing the formwork 1, and improves the construction speed. On the other hand, the tensioning quick-connect mechanism 8 applies a tensioning tension to the splicing of the formwork 1, so that the formwork 1 is not easy to be displaced or deformed during the concrete pouring process, and the gap is generated, which improves the sealing of the structure, ensures that the structure size is accurate and the surface is flat after the concrete is poured, reduces the later finishing work, and improves the overall quality of the construction project. At the same time, the connecting rod 6 is tilted to disperse the horizontal tension between the two adjacent formworks 1 to other directions, enhances the compressive strength of the formwork 1 during the concrete pouring process, and further makes it difficult for the two adjacent formworks 1 to have gaps under the huge pressure of pouring concrete.

[0032] In some embodiments, reference Figure 3 and Figure 4 The tensioning quick-connect mechanism 8 includes a driving assembly 81 disposed between the plurality of connecting rods 6, and the driving assembly 81 is used to drive the plurality of connecting rods 6 to move synchronously, and lock the position of the connecting rods 6 after the movement. A tensioning assembly 82 is disposed between the connecting rods 6 and the template 1, and the tensioning assembly 82 is used to apply a certain tensioning force between two adjacent templates 1 through the connecting rods 6. A fixing assembly 83 is disposed between the connecting rods 6 and the connecting block 7, and the fixing assembly 83 is used to connect and fix the connecting rods 6 and the connecting block 7.

[0033] During the splicing process of the template 1, the driving assembly 81 is first started, and the driving assembly 81 drives all the connecting rods 6 to move synchronously, and then the connecting rods 6 begin to move toward the connecting block 7 on the side of the adjacent template 1, and the tensioning assembly 82 starts to work. As the connecting rods 6 gradually move into the connecting block 7, the tensioning force applied by the connecting rods 6 between the two adjacent templates 1 gradually increases until they are fully inserted into the connecting block 7. The driving assembly 81, the tensioning assembly 82, and the fixing assembly 83 are used in coordination, so that the connecting rods 6 are tightly connected between the two adjacent templates 1, and the tensioning force is continuously applied to the splicing of the templates 1, so that the templates 1 are not easily displaced or deformed during the concrete pouring process, ensuring that the structural dimensions after the concrete pouring are accurate and the surface is flat, reducing the later finishing work, and improving the overall quality of the construction project.

[0034] In some embodiments, reference Figure 3 and Figure 5 The driving assembly 81 includes a driving rack 811 fixedly mounted in the middle of the connecting rod 6; a plurality of rotating shafts 812 are rotatably connected to the template 1, and the plurality of rotating shafts 812 correspond to the plurality of connecting rods 6 one by one. A driving gear 813 is fixedly sleeved on the rotating shaft 812, and the driving gear 813 is meshed with the corresponding driving rack 811. A sprocket 814 is fixedly sleeved on the outer side of the rotating shaft 812, and a chain 815 is meshed on the outer side of two adjacent sprockets 814. A hand wheel 816 is fixedly mounted on one end of one of the rotating shafts 812, and a one-way locking component 817 is arranged between the template 1, and the one-way locking component 817 is used to lock the angle of the rotating shaft 812 after rotation.

[0035] When the driving assembly 81 synchronously drives the multiple connecting rods 6 to move, the construction personnel first rotate the hand wheel 816, and the hand wheel 816 drives the rotating shaft 812 fixedly connected thereto to rotate, and the rotating shaft 812 synchronously drives the multiple driving gears 813 to rotate through the linkage of the sprocket 814 and the chain 815, and the driving gear 813 can drive the connecting rods 6 fixedly connected thereto to move toward the connecting block 7 on the adjacent template 1. When the connecting rod 6 moves to be fully inserted into the connecting block 7, the rotating shaft 812 rotates to a predetermined angle, and the one-way locking component 817 locks the position of the rotating shaft 812 to prevent it from rotating in the reverse direction, thereby ensuring that the position of the connecting rod 6 is stable during the force application process of the tensioning assembly 82.

[0036] In some embodiments, reference Figure 6 and Figure 7 The one-way locking component 817 includes a locking sleeve 8171 fixedly mounted on the outer side of the template 1, and one end of the locking sleeve 8171 is fixedly connected to the template 1. A ratchet 8172 is fixedly sleeved on the outer side of the rotating shaft 812, and a locking shaft 8173 is rotatably connected to the locking sleeve 8171. A pawl 8174 is fixedly sleeved on the outer side of the locking shaft 8173, and the pawl 8174 is meshed with the ratchet 8172. A torsion spring 8175 is arranged between the locking shaft 8173 and the locking sleeve 8171, and the torsion spring 8175 always gives the pawl 8174 a force toward meshing with the ratchet 8172. A locking rod 8176 is provided at one end of the locking shaft 8173, and the locking rod 8176 is slidably inserted into the locking shaft 8173 along the length direction of the locking shaft 8173. For example, the locking shaft 8173 is provided with a spline groove along its length direction, and a spline is fixedly provided on the outer side of the locking rod 8176, and the spline is slidably inserted into the spline groove; and a knob 8177 is fixedly provided at one end of the locking rod 8176 away from the locking shaft 8173. A fixing frame 8178 is fixedly provided on the template 1, and a locking magnet 8179 is fixedly sleeved on the locking rod 8176, and the locking magnet 8179 and the fixing frame 8178 can be adsorbed to each other.

[0037] When the rotating shaft 812 rotates to a predetermined angle and the pawl 8174 engages with the ratchet 8172, the locking sleeve 8171 prevents the rotating shaft 812 from rotating in the opposite direction through the locking action of the pawl 8174 on the ratchet 8172, thereby locking the position of the rotating shaft 812 and ensuring the stability of the position of the connecting rod 6 after being inserted into the connecting block 7, thereby preventing displacement due to external force during the concrete pouring process. When the template 1 needs to be disassembled and the construction workers need to release the locking state of the one-way locking component 817 on the rotating shaft 812, they first turn the knob 8177, the knob 8177 drives the locking rod 8176 to rotate, the locking rod 8176 drives the locking shaft 8173 to rotate, the locking shaft 8173 drives the pawl 8174 to move to the side away from the ratchet 8172, so that the ratchet 8172 and the pawl 8174 are disengaged. At this time, the construction workers pull the locking rod 8176 to the side close to the fixed frame 8178, the locking rod 8176 drives the locking magnet 8179 to move, and the locking magnet 8179 is adsorbed onto the fixed frame 8178, so that the ratchet 8172 and the pawl 8174 can remain unlocked for a long time, thereby releasing the lock on the rotating shaft 812.

[0038] When the construction personnel need to lock the rotation angle of the rotating shaft 812, they only need to press the knob 8177 to make the locking rod 8176 drive the locking magnet 8179 to separate from the fixing frame 8178, and the pawl 8174 can rotate under the action of the torsion spring 8175 and resume the meshing state with the ratchet 8172. When the construction personnel need to release the locking state of the rotating shaft 812, they do not need to twist the locking shaft 8173 by hand for a long time to release the meshing state of the ratchet 8172 and the pawl 8174; and the one-way locking component 817 ensures that the rotating shaft 812 is locked at a predetermined angle through the meshing of the pawl 8174 and the ratchet 8172, thereby preventing the displacement of the connecting rod 6 during the concrete pouring process and improving the stability and sealing of the connection of the template 1.

[0039] In some embodiments, reference Figure 3The tensioning assembly 82 includes a support shaft 821 spaced apart at one end of the connecting rod 6, and a tensioning spring 822 is sleeved on the outer side of the support shaft 821. Two sliding sleeves 823 are sleeved on the outer side of the support shaft 821, and the two sliding sleeves 823 are respectively in contact with the two ends of the tensioning spring 822. Two symmetrically arranged connecting rod groups 824 are also arranged between the two sliding sleeves 823; each connecting rod group 824 includes two tension connecting rods 8241 respectively hinged on the two sliding sleeves 823, and a support seat 8242 hinged to the ends of the two tension connecting rods 8241 away from the sliding sleeve 823. The two tension connecting rods 8241 in the same connecting rod 6 group are symmetrically arranged. One of the support seats 8242 in the two connecting rod groups 824 is fixedly connected to the template 1, and the other support seat 8242 is fixedly connected to the connecting rod 6. A fixed limit block 825 is fixedly provided at one end of the support shaft 821, and a movable limit block 826 is detachably connected to the end of the support shaft 821 away from the fixed limit block 825 through a thread, wherein the setting of the fixed limit block 825 and the movable limit block 826 is used to improve the stability of the tensioning spring 822 during use, prevent the tensioning spring 822 from detaching from the support shaft 821 during compression or release, and improve the reliability of the tensioning assembly 82.

[0040] When the connecting rod 6 starts to move toward and plug into the connecting block 7 on the adjacent template 1, the tensioning assembly 82 starts to be activated. At this time, the movement of the connecting rod 6 has not yet generated a force on the tensioning assembly 82. As the connecting rod 6 is plugged into the connecting block 7, the movement of the connecting rod 6 drives the support seat 8242 fixedly connected thereto to move, and then through the tensioning connecting rod 8241 in the connecting rod assembly 824, the two sliding sleeves 823 move toward the center position of the support shaft 821, compressing the tensioning spring 822. At this time, the tensioning spring 822 stores energy and generates a tensioning force on the connecting rod 6 until the connecting rod 6 is fully plugged in and locked into the connecting block 7.

[0041] When the tension spring 822 needs to be replaced due to long-term use or damage, the construction personnel can rotate and disassemble the movable stop block 826, remove the tension spring 822 from the support shaft 821, replace the new tension spring 822, and reinstall the movable stop block 826, thereby increasing the service life of the tension assembly 82. The tensioning force of the tension spring 822 is transmitted to the connecting rod 6 and the template 1 through the use of the sliding sleeve 823, the tension link 8241, the support seat 8242, etc., so that the position of the connecting rod 6 at the connection of the template 1 is stable, so that the adjacent template 1 is not easily displaced due to external force during the concrete pouring process, and the stability and sealing of the connection of the template 1 are improved until the template 1 is disassembled and the compression force of the tension spring 822 is released.

[0042] In some embodiments, reference Figure 3-Figure 5The fixing assembly 83 includes a plurality of fixing blocks 831 slidably connected to the template 1. The plurality of fixing blocks 831 correspond to the plurality of connecting rods 6 one by one. The connecting rods 6 are provided with a plurality of fixing grooves 61 along their length direction. The fixing blocks 831 can be inserted into the fixing grooves 61. The fixing blocks 831 are provided with an inclined surface on one side close to the connecting rods 6. A moving frame 832 is provided between the plurality of fixing blocks 831. The moving frame 832 is slidably connected to the template 1. A fixing spring 833 is fixed between each fixing block 831 and the moving frame 832. A handle 834 is fixed on the moving frame 832. One end of the handle 834 passes through the template 1 and is located outside the template 1. The template 1 is provided with an inclined moving groove 11. The handle 834 can slide in the moving groove 11.

[0043] When the connecting rod 6 moves toward and plugs into the connecting block 7 on the adjacent template 1, the inclined surface of the fixing block 831 enables the connecting rod 6 to slide along the inclined surface when the fixing block 831 and the connecting rod 6 are initially in contact, without causing jamming due to direct contact, until the connecting rod 6 is fully inserted into the connecting block 7, and the fixing block 831 is plugged into the fixing groove 61 on the connecting rod 6 to fix the connecting rod 6. When it is necessary to release the fixing of the connecting rod 6 by the fixing assembly 83, the construction personnel first push the moving frame 832 upwards through the handle 834, and the moving frame 832 drives the fixing block 831 to slide upwards along the template 1, so that the fixing block 831 is out of the fixing groove 61. The inclined surface of the fixing block 831 reduces the direct contact area between the fixing block 831 and the connecting rod 6, reduces the friction, and makes the plugging process of the connecting rod 6 smoother. At the same time, after the fixing block 831 is inserted into the fixing groove 61, the fixing spring 833 is compressed and continuously applies thrust to the fixing block 831, so that the fixing block 831 is not easily affected by vibration or other external forces and detached from the fixing groove 61 during the concrete pouring process, thereby improving the stability of the fixing component 83.

[0044] The present application also discloses a modular construction method for a lightweight all-aluminum prefabricated formwork structure, which is applicable to the above-mentioned lightweight all-aluminum prefabricated formwork structure, and the construction steps are as follows: S1. Level the construction surface to ensure the flatness of the ground and mark the lines.

[0045] S2. Align and arrange adjacent templates 1 in sequence according to design requirements, then space the inner mold 2 and the outer mold 3 according to design requirements, and support the template 1 through the diagonal support bracket 4.

[0046] S3. The connection rod 6 is driven to be inserted and fixed into the connection block 7 through the tensioning quick-connect mechanism 8 between two adjacent templates 1, and at the same time, a tensioning force is applied to the joint of the two adjacent templates 1 to ensure that the templates 1 are tightly connected.

[0047] S4. Then, concrete is poured into the closed pouring chamber 5 according to the construction specifications. Shear walls, columns, and beams are poured first, and then the horizontal floor slabs are poured. The pouring is carried out in multiple times and continuously. During the concrete pouring process, the uniformity and density of the concrete are ensured to avoid the generation of voids and cracks.

[0048] S5. After the concrete reaches the designed strength, it is cured. After the concrete wall panel reaches sufficient strength, the formwork 1 can be removed. First, the outer formwork 3 is removed, and then the inner formwork 2 is removed to avoid damage to the concrete structure.

[0049] The implementation principle of a lightweight all-aluminum prefabricated formwork structure and its modular construction method in the embodiment of the present application is as follows: when carrying out construction, first align and arrange adjacent formworks 1 in sequence according to design requirements, then set the inner formwork 2 and the outer formwork 3 at intervals according to design requirements, and then drive the connecting rod 6 to be inserted and fixed into the connecting block 7 through the tensioning quick-connect mechanism 8 between the two adjacent formworks 1, and at the same time apply tensioning force to the joints of the two adjacent formworks 1 to ensure that the formworks 1 are tightly connected; after the formworks 1 are spliced, a closed pouring chamber 5 is formed, and then concrete is poured according to the construction specifications, and the density and uniformity of the concrete are ensured during the pouring process; after the concrete reaches the designed strength, it is cured, and after the concrete wall panel reaches sufficient strength, the formwork 1 can be removed, first the outer formwork 3 is removed, and then the inner formwork 2 is removed to avoid damage to the concrete structure; wherein On the one hand, by using the connecting rod 6, the tensioning quick-connect mechanism 8, etc. in combination, there is no need to install and remove a large number of bolts during the entire installation and disassembly process of the inner mold 2 and the outer mold 3, which simplifies the splicing and disassembly process of the template 1, significantly reduces the splicing time of the template 1, and improves the construction speed. On the other hand, the tensioning quick-connect mechanism 8 applies a tensioning force to the splicing of the template 1, so that the template 1 is not easily displaced or deformed during the concrete pouring process, resulting in gaps, thereby improving the sealing of the structure, ensuring that the structure size is accurate and the surface is flat after the concrete is poured, reducing the subsequent finishing work, and improving the overall quality of the construction project; at the same time, the connecting rod 6 is inclined to disperse the horizontal tension between the two adjacent templates 1 to other directions, thereby enhancing the compressive strength of the template 1 during the concrete pouring process, and further preventing the two adjacent templates 1 from producing gaps under the huge pressure of pouring concrete.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
