Description

Technical Field

[0001] The present application relates to the technical field of house construction, and in particular to a super-high parapet quick-install formwork and a construction method. Background Art

[0002] A parapet is a low wall around the roof of a building. In addition to maintaining safety, its main function is to apply waterproof bricks at the bottom to prevent water seepage from the waterproof layer or rainwater from the roof from overflowing.

[0003] In the prior art, parapet construction is usually done by manual stacking. Manual stacking is very simple for parapets of normal height. However, for the stacking of super-high parapets, construction workers need to use scaffolding for stacking. Because the parapet has not been completed, it is very dangerous for construction workers to stack on the scaffolding. In order to solve this technical problem, the prior art requires construction workers to wear a safety rope when they are working on the scaffolding. The safety rope is used to bind the construction workers to the scaffolding, thereby improving the safety of the construction workers on the scaffolding. However, the construction workers tied with the safety rope are always restricted by the safety rope when they are working, which delays the construction efficiency of the construction workers. Therefore, a super-high parapet quick-install template and construction method are needed. Summary of the invention

[0004] In view of the shortcomings of the existing technology, the purpose of this application is to provide a super-high parapet wall quick-install formwork and construction method, which is used to solve the technical problems in the existing technology that the construction efficiency of super-high parapet walls is low and has certain safety hazards.

[0005] The above-mentioned purpose of the present application is achieved through the following technical solutions: a super-high parapet wall quick-install formwork, including a fixed formwork and a movable formwork, fixed blocks extending laterally on both sides of the lower end of the fixed formwork, a fixing assembly is provided at the end of the fixed block away from the fixed formwork, the fixing assembly includes a fixing plate fixedly connected to the fixed block and fixing nails nailed into the ground through the fixing plate, a connecting structure for fixing the movable formwork to the fixed formwork is provided at the bottom end of the movable formwork and the upper surface of the fixed block, and a gap is left between the movable formwork and the fixed formwork.

[0006] By adopting the above technical scheme, when it is necessary to build an ultra-high parapet wall, the fixed template is hoisted to the edge of the top surface of the building by a crane, and then the construction workers use fixing nails to pass through the fixing plate and nail it into the ground to fix the fixed template, and then the movable template is hoisted and installed on the fixed block through the connecting structure to form a casting space between the fixed template and the movable template. The construction workers surround the edge of the top surface of the building with the fixed template and the movable template to form a casting space with an upper opening and a side closed, and pour concrete into the casting space between the fixed template and the movable template. After waiting for the concrete to solidify, the movable template and the fixed template are disassembled to complete the construction of the ultra-high parapet wall. In this way, the construction workers can build the parapet wall in a safe environment and improve the construction efficiency of the construction workers. The setting of the fixed block can make the lower end of the completed parapet wall have multiple drainage outlets that penetrate the parapet wall, so that the construction workers only need to wait for the concrete to solidify after pouring, and there is no need to punch drainage outlets, which reduces the workload of the construction workers and improves the construction efficiency of the construction workers.

[0007] Furthermore, the connection structure includes a vertical connection groove formed on the upper surface of the fixed block and a connection piece fixedly connected to the bottom surface of the movable template.

[0008] By adopting the above technical solution, when hoisting the moving template, the connecting piece is aligned with the connecting groove, and then the moving template is lowered to insert the connecting piece into the connecting groove, and the installation of the moving template can be completed, which is very convenient.

[0009] Furthermore, a supporting device is provided on a side of the movable template away from the fixed template.

[0010] Furthermore, the support device includes a support rod with one end rotatably connected to the upper end of the movable template, an abutment plate located at the other end of the support rod and fixedly connected to the support rod, and a support nail nailed into the ground through the abutment plate, and the abutment plate extends laterally away from the movable template.

[0011] By adopting the above technical solution, although the setting of the movable formwork and the fixed formwork enables the construction workers to build the parapet in a safe environment and improve the construction efficiency of the construction workers, the height of the super-high parapet is too high, and only the bottom ends of the movable formwork and the fixed formwork are fixed. This causes the pressure of the concrete during pouring, causing the upper end of the movable formwork to expand outward, while the bottom end of the movable formwork is fixed. This expansion may cause the bottom end of the movable formwork to break. The setting of the support device solves this technical problem by rotating the support rod to an inclined state so that the abutment plate abuts the ground, and then using support nails to pass through the abutment plate and nail them into the ground to fix the support rod. In this way, the support rod can provide support force to the movable formwork, thereby preventing the bottom end of the movable formwork from breaking.

[0012] Furthermore, two opposite fixing rubbers are provided on one side of the movable template away from the fixed template, a gap is left between the two fixing rubbers and limiting rubbers are extended toward each other at one end close to the support rod, and the fixing rubbers and limiting rubbers are both elastic.

[0013] By adopting the above technical solution, although the setting of the support rod can prevent the bottom end of the movable formwork from breaking, when the movable formwork is hoisted and transported, the movable formwork shakes during the movement, which will cause the support rod to rotate on the movable formwork, resulting in the hoisting personnel and the transportation personnel needing to pay attention to the position of the support rod to prevent the shaking support rod from hitting the construction personnel, which is very inconvenient. The setting of the fixed rubber and the limiting rubber solves this technical problem. Before hoisting and transporting the movable formwork, the support rod is rotated so that the support rod squeezes the limiting rubber and is located between the two fixed rubbers. The squeezed limiting rubber rebounds from blocking the support rod due to its own elasticity, so that the support rod can be fixed to prevent the support rod from affecting the movement of the movable formwork during hoisting and transportation of the movable formwork, making it more convenient for construction personnel to hoist and transport the movable formwork.

[0014] Furthermore, a connecting device is provided at the upper end of the opposite sides of the fixed template and the movable template, and the connecting device includes a connecting block fixedly connected to the fixed template and a plug-in block plugged into the movable template relative to the connecting block, the connecting block is hollow inside and has an opening toward the plug-in block, and the plug-in block passes through the movable template and through the opening relative to one end of the movable template.

[0015] By adopting the above technical solution, although the setting of the supporting device provides support for the upper end of the movable template to effectively prevent the movable template from breaking, after the movable template is supported, the pressure acts on the fixed template, making the connection point of the fixed block of the fixed template easy to break when subjected to the pressure of concrete. The setting of the connecting device solves this technical problem. After the movable template is installed on the fixed template and the supporting device is installed, the plug-in block is pushed into the connecting block, so that there is a certain friction when the upper end of the fixed template expands outward, thereby reducing the occurrence of fixed template breakage.

[0016] Furthermore, the connecting block and the plug-in block are provided with a limiting device for fixing the upper end of the fixed template to the upper end of the movable template.

[0017] Furthermore, the limiting device includes a ratchet located in the connecting block and rotatably connected to the connecting block, a limiting rod extending from the upper end of the end surface of one end of the plug-in block opposite to the connecting block, and a pawl rotatably connected to the limiting rod and cooperating with the ratchet, and the tooth groove of the ratchet is facing away from the movable template.

[0018] By adopting the above technical solution, although the friction force when the upper end of the fixed template expands outward can be increased by the connecting device to reduce the occurrence of the fixed template breakage, it still cannot completely prevent the fixed template from breaking. It is easy for technicians in this field to directly set a device that can fix the upper end of the fixed template on the upper end of the fixed template. However, the setting of this device makes it difficult to disassemble the fixed template. The setting of the limiting device allows the upper end of the fixed template to be fixed without affecting the disassembly of the fixed template. After the movable template is installed on the fixed template and the supporting device is installed, the plug-in block is pushed into the connecting block, so that The pawl rubs the arc of the ratchet and is clamped into the tooth groove of the ratchet, so that when the fixed template expands in the direction away from the movable template due to pressure, the pawl presses against the ratchet to clamp the entire connecting block to limit the expansion of the fixed template in the direction away from the movable template, so that the upper end of the fixed template can be fixed by the limiting device, and when the fixed template is removed, the plug-in block is pulled in the direction away from the fixed template. At this time, the pawl pushes the ratchet to rotate so that the plug-in block can be smoothly separated from the connecting block, which makes it very convenient to remove the fixed template, thereby achieving the purpose of fixing the upper end of the fixed template without affecting the removal of the fixed template.

[0019] Furthermore, limiting plates are provided on both sides of the plug-in block away from the fixed template, and a pull ring is provided on the end surface of the plug-in block away from the fixed template.

[0020] By adopting the above technical solution, the limit plate can prevent the fixed template from expanding in the direction away from the movable template due to pressure, which drives the plug-in block to move and causes the limit device to fail, and the pull ring makes it easy for construction workers to pull the plug-in block.

[0021] The construction method applied to the above-mentioned super-high parapet quick-install formwork comprises the following steps:

[0022] S1. First, hoist the fixed template to the edge of the building top surface, and then drive the fixing nails from the fixing plate into the ground to fix the fixed template;

[0023] S2. Lift the movable template to the top of the connecting groove, align the connecting piece with the connecting groove, and then lower the movable template so that the connecting piece is inserted into the connecting groove;

[0024] S3, rotating the support rod to make the abutment plate abut against the ground, and then driving the support nails into the abutment plate to fix the support rod;

[0025] S4, pushing the plug-in block to insert the plug-in block into the connecting block, so that the pawl abuts against the ratchet wheel;

[0026] S5. Pour concrete between the fixed formwork and the movable formwork, and remove the fixed formwork and the movable formwork after the concrete cools down.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. Through the setting of the fixed formwork and the movable formwork, when it is necessary to build an ultra-high parapet wall, the fixed formwork is hoisted to the edge of the top surface of the building by a crane, and then the construction workers use fixing nails to pass through the fixed plate and nail it into the ground to fix the fixed formwork, and then hoist the movable formwork to align the connecting piece with the connecting groove, and then lower the movable formwork to insert the connecting piece into the connecting groove, so that a casting space is formed between the fixed formwork and the movable formwork. After the construction workers surround the edges of the top surface of the building with the fixed formwork and the movable formwork, they pour concrete into the casting space between the fixed formwork and the movable formwork, and wait for the concrete to solidify before disassembling the movable formwork and the fixed formwork to complete the construction of the ultra-high parapet wall. In this way, the construction workers can build the parapet wall in a safe environment and improve the construction efficiency of the construction workers. The setting of the fixed block can make the lower end of the completed parapet wall have multiple drainage outlets that penetrate the parapet wall, so that the construction workers only need to wait for the concrete to solidify after pouring, and no drainage outlet is needed, which reduces the workload of the construction workers and improves the construction efficiency of the construction workers.

[0029] 2. Through the setting of the supporting device, it is achieved by rotating the support rod to an inclined state so that the abutment plate abuts the ground, and then the support nails are passed through the abutment plate and nailed into the ground to fix the support rod. In this way, the support rod can provide supporting force to the moving template, thereby preventing the bottom end of the moving template from breaking.

[0030] 3. Through the setting of the connecting device and the limiting device, it is achieved that the movable template is installed on the fixed template. After the supporting device is installed, the plug-in block is pushed into the connecting block so that the pawl rubs the arc of the ratchet and is clamped into the tooth groove of the ratchet. In this way, when the fixed template expands in the direction away from the movable template due to pressure, the pawl presses against the ratchet to clamp the entire connecting block to limit the expansion of the fixed template in the direction away from the movable template. In this way, the upper end of the fixed template can be fixed by the limiting device, and when the fixed template is removed, the plug-in block is pulled in the direction away from the fixed template. At this time, the pawl pushes the ratchet to rotate so that the plug-in block can be smoothly separated from the connecting block. In this way, it is very convenient to remove the fixed template, so that the upper end of the fixed template can be fixed without affecting the purpose of removing the fixed template.

DETAILED DESCRIPTION

[0036] The present application is further described in detail below in conjunction with the accompanying drawings.

[0037] Example, see Figure 1 , Figure 2 A super-high parapet wall quick-install formwork, comprising a fixed formwork 1 and a movable formwork 2, fixed blocks 10 extending laterally from both sides of the lower end of the fixed formwork 1, a fixing assembly 3 is provided at one end of the fixed block 10 away from the fixed formwork 1, the fixing assembly 3 comprises a fixing plate 30 fixedly connected to the fixing block 10 and a fixing nail 31 nailed into the ground through the fixing plate 30, a connecting structure 4 for fixing the movable formwork 2 to the fixed formwork 1 is provided at the bottom end of the movable formwork 2 and the upper surface of the fixing block 10, a gap is left between the movable formwork 2 and the fixed formwork 1, the connecting structure 4 comprises a vertical connecting groove 40 provided on the upper surface of the fixing block 10 and a connecting piece 41 fixedly connected to the bottom surface of the movable formwork 2, when it is necessary to build a super-high parapet wall, the fixed formwork 1 is hoisted to the edge of the top surface of the building by a crane, and then the construction personnel nail the fixing nail 31 through the fixing plate 30 into the ground to fix the fixed formwork 1, and then the movable formwork 2 is hoisted to make the connecting piece 41 Align the connecting groove 40, then lower the movable formwork 2 so that the connecting piece 41 is inserted into the connecting groove 40, so that a casting space is formed between the fixed formwork 1 and the movable formwork 2, and the construction workers surround the edges of the top surface of the building with the fixed formwork 1 and the movable formwork 2 to form a casting space with an upper opening and a side closed, and pour concrete into the casting space between the fixed formwork 1 and the movable formwork 2. After waiting for the concrete to solidify, the movable formwork 2 and the fixed formwork 1 are disassembled to complete the construction of the super-high parapet. In this way, the construction workers can build the parapet in a safe environment and improve the construction efficiency of the construction workers. The setting of the fixed block 10 can make the lower end of the completed parapet have multiple drainage outlets that are opened through the parapet, so that after the pouring is completed, the construction workers only need to wait for the concrete to solidify, and there is no need to open drainage outlets, which reduces the workload of the construction workers and improves the construction efficiency of the construction workers.

[0038] Although the arrangement of the movable formwork 2 and the fixed formwork 1 enables the construction workers to build the parapet in a safe environment and improves the construction efficiency of the construction workers, the height of the super-high parapet is too high, and only the bottom ends of the movable formwork 2 and the fixed formwork 1 are fixed. This causes the upper end of the movable formwork 2 to expand outwards due to the pressure of the concrete during pouring, while the bottom end of the movable formwork 2 is fixed. This expansion may cause the bottom end of the movable formwork 2 to break. In order to solve this technical problem, in this embodiment, a support device is provided on the side of the movable formwork 2 away from the fixed formwork 1. The supporting device 5 includes a supporting rod 50 having one end rotatably connected to the upper end of the movable template 2, an abutment plate 51 located at the other end of the supporting rod 50 and fixedly connected to the supporting rod 50, and a supporting nail 52 nailed into the ground through the abutment plate 51. The abutment plate 51 extends in a direction away from the movable template 2. By rotating the supporting rod 50 to an inclined state, the abutment plate 51 abuts against the ground, and then the supporting nail 52 is nailed into the ground through the abutment plate 51 to fix the supporting rod 50. In this way, the supporting rod 50 can provide supporting force to the movable template 2, thereby preventing the bottom end of the movable template 2 from breaking.

[0039] Although the setting of the support rod 50 can prevent the bottom end of the movable template 2 from breaking, when the movable template 2 is hoisted and transported, the movable template 2 shakes during the movement, which will cause the support rod 50 to rotate on the movable template 2, causing the hoisting personnel and the transportation personnel to pay attention to the position of the support rod 50 to prevent the shaking support rod 50 from hitting the construction personnel, which is very inconvenient. In order to solve this technical problem, in this embodiment, two relative fixing rubbers 20 are provided on the side of the movable template 2 away from the fixed template 1, and a gap is left between the two fixing rubbers 20 and close to the support rod 50. One end of the limit rubber 21 extends toward each other, and the fixed rubber 20 and the limit rubber 21 are both elastic. Before hoisting and transporting the movable formwork 2, the support rod 50 is rotated so that the support rod 50 squeezes the limit rubber 21 and is located between the two fixed rubbers 20. The squeezed limit rubber 21 rebounds from blocking the support rod 50 due to its own elasticity. In this way, the support rod 50 can be fixed to prevent the support rod 50 from affecting the movement of the movable formwork 2 when hoisting and transporting the movable formwork 2, making it more convenient for construction workers to hoist and transport the movable formwork 2.

[0040] Although the setting of the supporting device 5 provides support for the upper end of the movable template 2, which can effectively prevent the movable template 2 from breaking, after the movable template 2 is supported, the pressure acts on the fixed template 1, which makes the connection point of the fixed block 10 of the fixed template 1 easy to break when subjected to the pressure of concrete. In order to solve this technical problem, in this embodiment, a connecting device 6 is provided at the upper end of the opposite side of the fixed template 1 and the movable template 2. The connecting device 6 includes a connecting block 60 fixedly connected to the fixed template 1 and a plug-in block 61 plugged into the movable template 2 relative to the connecting block 60. The connecting block 60 is hollow inside and has an opening 62 facing the plug-in block 61. The plug-in block 61 passes through the movable template 2 and passes through one end of the movable template 2 relative to the opening 62. After the movable template 2 is installed on the fixed template 1 and the supporting device 5 is installed, the plug-in block 61 is pushed to be inserted into the connecting block 60, so that there is a certain friction when the upper end of the fixed template 1 expands outward, thereby reducing the occurrence of fixed template 1 breakage.

[0041] Although the friction force when the upper end of the fixed template 1 expands outward by the connecting device 6 can reduce the occurrence of the fixed template 1 breaking, it still cannot completely prevent the fixed template 1 from breaking. It is easy for a person skilled in the art to directly set a device that can fix the upper end of the fixed template 1 on the upper end of the fixed template 1. However, the setting of this device makes it difficult to disassemble the fixed template 1. In order to solve this technical problem, reference is made to Figure 3 , Figure 4In this embodiment, a limiting device 7 is provided on the connecting block 60 and the plug-in block 61 for fixing the upper end of the fixed template 1 to the upper end of the movable template 2. The limiting device 7 includes a ratchet 70 located in the connecting block 60 and rotatably connected to the connecting block 60, a limiting rod 71 extending from the upper end of the end surface of the plug-in block 61 opposite to the connecting block 60, and a pawl 72 that is rotatably connected to the limiting rod 71 and cooperates with the ratchet 70. The tooth groove of the ratchet 70 faces the direction away from the movable template 2. After the movable template 2 is installed on the fixed template 1 and the supporting device 5 is installed, the plug-in block 61 is pushed and inserted into the connecting block 60, so that the pawl 72 rubs the arc of the ratchet 70 and is clamped into the tooth groove of the ratchet 70. In this way, when the fixed template 1 expands in the direction away from the movable template 2 due to pressure, the pawl 72 presses against the ratchet 70, thereby clamping the entire connecting block 60 to limit The fixed template 1 expands in the direction away from the movable template 2, so that the upper end of the fixed template 1 can be fixed by the limiting device 7, and when the fixed template 1 is disassembled, the plug-in block 61 is pulled in the direction away from the fixed template 1. At this time, the pawl 72 pushes the ratchet 70 to rotate so that the plug-in block 61 can be smoothly separated from the connecting block 60, so that it is very convenient to disassemble the fixed template 1, and the purpose of fixing the upper end of the fixed template 1 without affecting the disassembly of the fixed template 1 is achieved. Limiting plates 73 are provided on both sides of the plug-in block 61 away from the end of the fixed template 1, and a pull ring 74 is provided on the end face of the plug-in block 61 away from the end of the fixed template 1. The limiting plates 73 can prevent the fixed template 1 from expanding in the direction away from the movable template 2 due to pressure, which drives the plug-in block 61 to move, resulting in failure of the limiting device 7, and the pull ring 74 facilitates the construction personnel to pull the plug-in block 61.

[0042] Specific implementation process: first, hoist the fixed formwork 1 to the edge of the top surface of the building, then nail the fixing nails 31 from the fixing plate 30, so that the fixing nails 31 are nailed into the ground to fix the fixed formwork 1, and then hoist the movable formwork 2 to the top of the connecting groove 40, align the connecting piece 41 with the connecting groove 40, and then lower the movable formwork 2 to insert the connecting piece 41 into the connecting groove 40, and then rotate the support rod 50 to make the abutment plate 51 abut the ground, and then nail the supporting nails 52 from the abutment plate 51 to fix the support rod 50, and then push the plug-in block 61 to insert the plug-in block 61 into the connecting block 60, so that the pawl 72 abuts the ratchet 70, and then pour concrete between the fixed formwork 1 and the movable formwork 2, and wait for the concrete to cool before removing the fixed formwork 1 and the movable formwork 2.

[0043] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
