Description

Technical Field

[0001] This application relates to the field of building construction technology, and in particular to a method for constructing concrete walls using wooden formwork without drilling. Background Technology

[0002] Currently, with the improvement of living standards, people have increasingly higher requirements for housing. Traditional construction methods, which are time-consuming and labor-intensive, no longer meet people's needs. Therefore, in order to build quickly and stably, people use the casting method to complete the construction of buildings. The installation of concrete wall formwork is one of the key steps. The traditional method of installing formwork is to use bolts to fix wooden formwork to the wall. This requires drilling holes in both the formwork and the wall, and then tightening with bolts.

[0003] However, traditional drilling connection methods can damage the integrity of the wall and affect its seismic performance. Frequent drilling operations can also accelerate the wear and tear on the wooden formwork. Summary of the Invention

[0004] To improve the integrity of the wall and reduce the wear and tear on the wooden formwork, this application provides a method for constructing concrete walls using wooden formwork without drilling.

[0005] This application provides a method for constructing concrete walls using wooden formwork without drilling, employing the following technical solution:

[0006] A method for constructing concrete walls using wooden formwork without drilling includes wooden formwork and clamping devices, and specifically includes the following steps:

[0007] S1: Prepare the wooden template and the clamping device;

[0008] S2: Place the wooden template at the location of the concrete wall to be constructed;

[0009] S3: Use the clamping device to clamp and fix the wooden template;

[0010] S4: Concrete pouring is carried out. After the concrete has solidified, the clamping device is removed and the wooden formwork is taken down.

[0011] By adopting the above technical solution, before operation, the workers prepare the wooden formwork and clamping devices. Then, the workers place the wooden formwork at the location of the concrete wall to be constructed. Subsequently, the workers use the clamping devices to strengthen the connection between the wooden formwork and maintain its stability. Then, the concrete is poured. During the concrete pouring, the clamping devices can reduce the possibility of the wooden formwork tipping over due to the impact force of the concrete. After the concrete has solidified, the workers remove the clamping devices and take off the wooden formwork.

[0012] Preferably, a clamping device is included, the clamping device comprising a pre-clamping component and a reinforcing clamping component, the pre-clamping component comprising two pre-clamping plates and a rotating column, the two pre-clamping plates rotating toward or away from each other on the rotating column, a torsion spring being sleeved on the rotating column, the two torsion arms of the torsion spring being fixedly connected to the two pre-clamping plates respectively, an insert block being fixedly connected to the pre-clamping plate, and a slot for inserting the insert block being provided on the wooden template.

[0013] By adopting the above technical solution, the two pre-clamping plates are in a closed state under the action of torsion springs. After the workers place the two adjacent wooden templates, they overcome the spring force of the torsion springs to open the pre-clamping plates and insert the inserts on the two pre-clamping plates into the slots on the two adjacent wooden templates respectively. Under the action of the torsion springs, the two pre-clamping plates clamp the side walls of the two adjacent wooden templates, thereby enhancing the connection between the adjacent wooden templates and making it easier for the workers to place subsequent wooden templates.

[0014] Preferably, the reinforcing clamping component includes a column and multiple clamping frames. The column is provided with a sliding groove, and the multiple clamping frames slide within the sliding groove. Each clamping frame is provided with a fixing component for fixing the clamping frame.

[0015] The clamping frame is slidably provided with two reinforcing clamping plates and two connecting rods. The two reinforcing clamping plates are respectively fixedly connected to the two connecting rods. A threaded tube is rotatably connected to the clamping frame. The two connecting rods are respectively threaded to both ends of the threaded tube. The clamping frame is provided with a limiting member for limiting the rotation of the connecting rods. The clamping frame is provided with a driving assembly for driving the threaded tube to rotate.

[0016] By adopting the above technical solution, after the workers have placed all the wooden templates, they use reinforcing clamping components to enhance the clamping effect on the wooden templates. First, the workers place the uprights close to the wooden templates. Then, the workers release the fixing components from the clamping frames and move the clamping frames to adjust their positions. After aligning the multiple clamping frames on the uprights with different heights of the wooden templates, the workers fix the clamping frames with the fixing components. Next, the workers drive the threaded tube to rotate using the drive component. Under the action of the limiting component, the connecting rod moves as the threaded tube rotates, thereby adjusting the distance between the two reinforcing clamping plates. This allows the reinforcing clamping plates to press tightly against the side wall of the wooden template, enhancing the stability of the wooden template and thus adapting to wooden templates of different sizes.

[0017] Preferably, the limiting member is a limiting block, the clamping frame has a through groove, the connecting rod passes through the through groove, the limiting block is fixedly connected to the inner wall of the through groove, the connecting rod has a limiting groove on its side wall, and the limiting block is slidably connected to the inner wall of the limiting groove.

[0018] By adopting the above technical solution, when the threaded tube rotates, the limiting block is inserted into the limiting groove of the connecting rod, thereby restricting the rotation of the connecting rod and driving the connecting rod to move in a straight line.

[0019] Preferably, the driving assembly includes a first worm gear, a first worm, a second worm gear, a second worm, and a motor. The motor is fixedly mounted on the column. The first worm gear is fixedly sleeved on the threaded tube. The first worm passes through the clamping frame and meshes with the first worm gear. The second worm gear is fixedly sleeved on the end of the first worm away from the first worm gear. The second worm rotates on the column. The shaft of the motor and the second worm are connected by a bevel gear set. The column is provided with a moving component that drives the second worm to move.

[0020] By adopting the above technical solution, when the operator adjusts the height of the clamping frame, the operator moves the second worm gear to a position away from the second worm wheel and fixes it using the moving component. When the operator needs to adjust the two reinforcing clamping plates to clamp the wooden template, the operator moves the second worm gear to the meshing position of the second worm wheel using the moving component. At this time, the second worm gear and the motor are connected through a bevel gear. The operator turns on the motor, and the second worm gear rotates under the drive of the bevel gear set. The second worm gear drives the second worm wheel to rotate, the second worm wheel drives the first worm gear to rotate, the first worm gear rotates to drive the first worm wheel to rotate, and the first worm wheel rotates to drive the threaded tube to rotate, thereby adjusting the distance between the two reinforcing clamping plates.

[0021] Preferably, the movable component includes a stand and a pull block. The stand is slidably connected to the inner wall of the slide groove, and the pull block is fixedly connected to the stand. The two ends of the second worm gear rotate on the opposite inner walls of the stand. The pull block passes through the inner wall of the slide groove. A connecting block is fixedly connected to the outer wall of the column. A pin passes through the connecting block. The pull block has a first insertion hole and a second insertion hole. The pin is inserted into the first insertion hole or the second insertion hole.

[0022] By adopting the above technical solution, when the worker needs to move the second worm, the worker first pulls out the pin in the first socket, then pulls the pull block outward. The movement of the pull block moves the upright, and the movement of the upright moves the second worm, thus moving the second worm away from the second worm wheel. Then, the worker inserts the pin into the second socket to fix the position of the second worm, which makes it easier for the worker to adjust the height of the clamping frame. When the worker needs to rotate the threaded tube, the worker pulls out the pin in the second socket and pushes the pull block inward. When the second worm and the fourth worm wheel mesh, the worker inserts the pin into the first socket to fix the second worm. Then, the worker starts the motor to drive the threaded tube to rotate.

[0023] Preferably, the fixing assembly includes two fixing blocks and a spring. The clamping frame has a placement groove. The two fixing blocks slide in the placement groove, either facing away from each other or towards each other. The two ends of the spring are fixedly connected to the opposite side walls of the two fixing blocks. The fixing blocks pass through the inner wall of the placement groove and abut against the inner wall of the sliding groove. A driving block and two hinge rods slide in the placement groove. The two ends of the hinge rods are respectively hinged to the driving block and the fixing block. A pull rod is fixedly connected to the driving block. The pull rod passes through and slides in the placement groove.

[0024] By adopting the above technical solution, when the operator needs to adjust the position of the clamping frame and move the second worm gear away from the fourth worm wheel, the operator pulls the lever to move. The movement of the lever drives the fixed block to compress the spring through the hinge rod. When the fixed block moves away from the inner wall of the slide, the operator drives the clamping frame to a suitable position and then releases the lever. At this time, the fixed block is pushed against the inner wall of the slide by the spring, thereby fixing the position of the clamping frame.

[0025] Preferably, a first locking block is fixedly connected to the clamping frame, and a second locking block is rotatably disposed on the pull rod. The second locking block has a locking groove, and the first locking block is engaged with the locking groove.

[0026] By adopting the above technical solution, after the worker pulls the lever to drive the fixed block away from the inner wall of the slide, the worker rotates the second locking block to make the first locking block engage in the slot, thereby fixing the lever and making it easier for the worker to move the clamping frame.

[0027] Preferably, a rubber pad is fixedly connected to the reinforcing clamping plate, and the rubber pad abuts against the wooden template.

[0028] By adopting the above technical solution, the rubber pad increases the friction between the reinforcing clamping plate and the wooden template, and reduces wear.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. Before operation, the workers prepare the wooden formwork and clamping devices. Then, they place the wooden formwork at the location of the concrete wall to be constructed. The workers then use the clamping devices to strengthen the connection between the wooden formwork and maintain its stability. After that, the concrete is poured. During the concrete pouring, the clamping devices can reduce the possibility of the wooden formwork tipping over due to the impact of the concrete. After the concrete has solidified, the workers remove the clamping devices and take down the wooden formwork.

[0031] 2. The two pre-clamping plates are in a closed state under the action of torsion springs. After the workers place the two adjacent wooden templates, they open the pre-clamping plates against the spring force of the torsion springs and insert the inserts on the two pre-clamping plates into the slots on the two adjacent wooden templates respectively. Under the action of the torsion springs, the two pre-clamping plates clamp the side walls of the two adjacent wooden templates, thereby strengthening the connection between the adjacent wooden templates and making it easier for the workers to place the subsequent wooden templates.

[0032] 3. After all the wooden formwork has been placed, the workers use reinforcing clamping components to enhance the clamping effect. First, the workers place the uprights close to the wooden formwork. Then, the workers release the fixing components from the clamping frames and move the clamping frames to adjust their positions. After aligning the multiple clamping frames on the uprights with different heights of the wooden formwork, the workers fix the clamping frames with the fixing components. Next, the workers drive the threaded tube to rotate using the drive component. Under the action of the limiting component, the connecting rod moves with the rotation of the threaded tube, thereby adjusting the distance between the two reinforcing clamping plates. This allows the reinforcing clamping plates to press tightly against the side wall of the wooden formwork, enhancing the stability of the wooden formwork and thus accommodating wooden formwork of different sizes.

[0041] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0042] Implementation 1

[0043] This application discloses a drilling-free construction method for wooden formwork 1 in concrete walls, including wooden formwork 1 and clamping device 2, specifically including the following steps:

[0044] S1: Prepare multiple wooden templates 1 and multiple clamping devices 2. The clamping device 2 includes a pre-clamping component 3 and a reinforcing clamping component 4.

[0045] S2: Place the wooden formwork 1 at the location of the concrete wall to be constructed. When placing adjacent wooden formwork 1, the workers use the pre-clamping component 3 to initially clamp and connect the two adjacent wooden formwork 1.

[0046] S3: After all the wooden templates 1 have been placed, use the clamping device 2 to clamp and fix the wooden templates 1.

[0047] S4: Concrete pouring is carried out. After the concrete has solidified, the clamping device 2 is removed and the wooden formwork 1 is taken off.

[0048] The implementation principle of Embodiment 1 of this application is as follows: Workers first prepare the wooden formwork 1 and clamping devices 2. They then place four wooden formwork 1s at the location of the concrete wall to be constructed, forming a pouring cavity. The four wooden formwork 1s are placed sequentially, with each formwork 1 abutting against the side wall of the previous formwork 1, thereby reducing the possibility of the formwork 1s tipping over into the pouring cavity before being fixed. Subsequently, workers use the clamping devices 2 to clamp the opposing wooden formwork 1s, with clamping devices 2 installed in all four directions to maintain the stability between the formwork 1s. Then, concrete is poured. During concrete pouring, the clamping devices 2 reduce the possibility of the wooden formwork 1s tipping over due to the impact force of the concrete. After the concrete has solidified, workers remove the clamping devices 2 and take down the wooden formwork 1s.

[0049] Implementation 2

[0050] Embodiment 2 of this application discloses a no-drill construction device for wooden formwork 1 for concrete walls, such as... Figure 1 and Figure 2 As shown, the device includes a clamping device 2, which includes a pre-clamping component 3 and a reinforcing clamping component 4. The pre-clamping component 3 includes two pre-clamping plates 5 and a rotating column 6. The rotating column 6 is cylindrical, and the pre-clamping plates 5 are cuboid. The two pre-clamping plates 5 rotate towards or away from each other on the peripheral sidewall of the rotating column 6. A torsion spring 7 is sleeved on the rotating column 6. The two torsion arms of the torsion spring 7 are respectively fixedly welded to the two pre-clamping plates 5. Under the elastic force of the torsion spring 7, the two pre-clamping plates 5 approach each other and are in a closed state.

[0051] like Figure 1 and Figure 2 As shown, two pre-clamping plates 5 have insert blocks 8 fixedly welded to their opposite sidewalls, and slots 9 for inserting the insert blocks 8 are provided on the outer sidewall of the wooden template 1. After the workers vertically place the two adjacent wooden templates 1, they overcome the spring force of the torsion spring 7 to open the pre-clamping plates 5 and insert the insert blocks 8 on the two pre-clamping plates 5 into the slots 9 on the two adjacent wooden templates 1 respectively. Under the action of the torsion spring 7, the two pre-clamping plates 5 clamp the sidewalls of the two adjacent wooden templates 1, thereby strengthening the connection between the adjacent wooden templates 1 and facilitating the workers to place subsequent wooden templates 1 and install the reinforcing clamping components 4.

[0052] like Figure 3 and Figure 4As shown, the reinforcing clamping frame 11 is installed on the four sides of the wooden template 1, which can increase the stability of the wooden template 1. The reinforcing clamping component 4 includes a column 10 and multiple clamping frames 11. The column 10 has a sliding groove 12. A vertical pole 42 is fixedly installed in the sliding groove 12. The clamping frame 11 is sleeved on and slides on the vertical pole 42. Multiple clamping frames 11 slide in the sliding groove 12 in the vertical direction. A fixing component 13 for fixing the clamping frame 11 is provided in the clamping frame 11. The fixing component 13 includes two fixing blocks 33 and a spring 34. A placement groove 35 is opened in the clamping frame 11. The two fixing blocks 33 slide in opposite directions or towards each other in the placement groove 35 in the horizontal direction and pass through the inner wall of the placement groove 35 and abut against the inner wall of the sliding groove 12. The spring 34 is horizontally installed in the placement groove 35 and its two ends are respectively fixedly welded to the opposite side walls of the two fixing blocks 33. A drive block 36 and two hinge rods 37 slide within the placement groove 35. The drive block 36 slides in a direction perpendicular to the fixed block 33. The two ends of the hinge rods 37 are respectively hinged to the drive block 36 and the fixed block 33. A pull rod 38 is fixedly welded to the drive block 36, and the pull rod 38 passes through and slides within the placement groove 35. A first locking block 39 is fixedly welded to the outer surface of the clamping frame 11. The first locking block 39 is cuboid in shape. A second locking block 40 is rotatably mounted on the pull rod 38. The second locking block 40 has a locking groove, and the first locking block 39 engages in the locking groove.

[0053] like Figure 3 and Figure 5 As shown, two reinforcing clamping plates 14 are horizontally slidable at both ends of the clamping frame 11. The two reinforcing clamping plates 14 are cuboid in shape, and rubber pads 41 are fixedly adhered to their opposite sidewalls. The rubber pads 41 abut against the wooden template 1, increasing the friction between the reinforcing clamping plates 14 and the wooden template 1, and reducing wear. Through grooves 19 are formed on the opposite sidewalls of the clamping frame 11, and connecting rods 15 pass through the through grooves 19. The connecting rods 15 are welded to the sidewalls of the reinforcing clamping plates 14. A threaded tube 16 is rotatably arranged between the two sidewalls of the clamping frame 11. The two connecting rods 15 are respectively threaded to the two ends of the threaded tube 16. The clamping frame 11 is provided with limiting members to restrict the rotation of the connecting rods 15. The limiting component is a limiting block 18, which is fixedly welded to the inner wall of the through groove 19. A limiting groove is formed on the side wall of the connecting rod 15. When the connecting rod 15 moves, the limiting block 18 is slidably connected to the clamping frame 11 on the inner wall of the limiting groove, thereby limiting the rotation of the connecting rod 15. The clamping frame 11 is provided with a drive assembly 17 for driving the threaded tube 16 to rotate.

[0054] like Figure 3 and Figure 6As shown, the drive assembly 17 includes a first worm gear 20, a first worm 21, a second worm gear 22, a second worm 23, and a motor 24. The motor 24 is fixedly installed on the top of the column 10. The first worm gear 20 is fixedly sleeved on the middle side wall of the threaded tube 16. The first worm 21 is horizontally arranged and passes through the clamping frame 11, meshing with the first worm gear 20. The end of the first worm 21 away from the first worm gear 20 rotates in the sliding groove 12. The second worm gear 22 is fixedly sleeved on the end of the first worm 21 away from the first worm gear 20. The second worm 23 passes through the column 10 vertically and rotates in the sliding groove 12. A bevel gear set 25 is fixedly sleeved on the rotating shaft of the motor 24. The bevel gear set 25 meshes with the top of the second worm 23. A moving assembly 26 is provided on the column 10 to drive the second worm 23 away from the second worm gear 22. The movable component 26 includes a support frame 27 and a pull block 28. The support frame 27 is C-shaped and is horizontally slidably connected to the inner wall of the slide groove 12. The pull block 28 is fixedly welded to the vertical side wall of the support frame 27 and can pass through the inner wall of the slide groove 12 to extend to the outside. The two ends of the second worm gear 23 rotate on the opposite inner walls of the horizontal side wall of the support frame 27. A connecting block 30 is fixedly welded to the outer wall of the column 10, and a pin 29 passes through the connecting block 30. A stop block is fixedly welded to the top of the device. The pull block 28 has a first insertion hole 31 and a second insertion hole 32 opened sequentially from the outside to the inside along the vertical direction. When the pin 29 is inserted into the first insertion hole 31, the second worm 23, the second worm wheel 22, and the bevel gear set 25 are all engaged. When the pin 29 is inserted into the second insertion hole 32, the second worm 23 and the second worm wheel 22 are not engaged. When the operator drives the clamping frame 11 to move, the second worm 23 does not affect the movement of the second worm wheel 22.

[0055] like Figure 1 and Figure 4 As shown, and in combination Figure 6As shown, after the workers have placed all the wooden templates 1 in sequence, they use the reinforcing clamping component 4 to strengthen the clamping effect on the wooden templates 1. First, the workers place the upright 10 close to the wooden template 1. Then, the workers pull out the pin 29 in the first insertion hole 31 and pull the pull block 28 to move outward. The movement of the pull block 28 causes the upright 27 to move away from the second worm gear 22. The movement of the upright 27 causes the second worm 23 to move, so that the second worm 23 moves away from the second worm gear 22. Then, the workers insert the pin 29 into the second insertion hole 32 to fix the position of the upright 27. Subsequently, the staff adjusted the height of each clamping frame 11 to ensure that the wooden formwork 1 was clamped and fixed at different heights, increasing its stability and resistance to concrete impact. The staff pulled the pull rod 38 away from the column 10. The movement of the pull rod 38 caused the fixing block 33 to compress the spring 34 and move in opposite directions through the hinge rod 37. When the fixing block 33 was away from the inner wall of the slide 12, the staff rotated the second locking block 40 to abut against the first locking block 39, thereby fixing the pull block 28 and facilitating the movement of the clamping frame 11. After the staff drove the clamping frame 11 to the appropriate position, the staff rotated the second locking block 40 to disengage from the first locking block 39 and released the pull rod 38. At this time, the fixing block 33 was pressed against the inner wall of the slide 12 by the spring 34, thereby fixing the position of the clamping frame 11.

[0056] like Figure 3 and Figure 6 As shown, after the height of the clamping frame 11 is adjusted, the operator starts the motor 24 and the bevel gear set 25 to rotate. The rotation of the bevel gear set 25 drives the second worm gear 23 to rotate, which in turn drives multiple second worm wheels 22 to rotate. The second worm wheels 22 drive the first worm gear 21 to rotate, which in turn drives the first worm wheel 20 to rotate. The first worm wheel 20 then drives the threaded tube 16 to rotate, thereby adjusting the distance between the two reinforcing clamping plates 14. This ensures that the reinforcing clamping plates 14 are pressed tightly against the side wall of the wooden template 1, enhancing the stability of the wooden template 1 and thus adapting to wooden templates 1 of different sizes. The clamping device 2 is installed on all four sides of the pouring cavity, with the clamping devices 2 on adjacent sides being staggered in height. After the concrete has solidified, the operator needs to remove the wooden template 1. First, the reinforcing clamping plates 14 are moved away from the wooden template 1 using the drive assembly 17, and then the column 10 is moved to a position away from the wooden template 1.

[0057] The implementation principle of Embodiment 2 of this application is as follows: After the workers have placed all the wooden templates 1, they use the reinforcing clamping component 4 to enhance the clamping effect on the wooden templates 1. First, the workers place the column 10 close to the wooden template 1. Then, the workers release the fixing component 13 from the clamping frame 11 and move the clamping frame 11 to adjust its position. After the multiple clamping frames 11 on the column 10 correspond to different heights of the wooden template 1, the clamping frame 11 is fixed by the fixing component 13. Next, the workers drive the threaded tube 16 to rotate by driving the drive component 17. Under the action of the limiting component, the connecting rod 15 moves with the rotation of the threaded tube 16, thereby adjusting the distance between the two reinforcing clamping plates 14, so that the reinforcing clamping plates 14 are pressed against the side wall of the wooden template 1, enhancing the stability of the wooden template 1, and thus adapting to wooden templates 1 of different sizes.

[0058] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
