Technical Field

[0001] The present application relates to the field of concrete wall construction, and in particular to a large concrete wall formwork support device. Background Art

[0002] The construction of large concrete wall formwork (basement, shear wall, various shafts, etc.) usually requires the use of tension screws, which is inconvenient, ineffective, and costly. If the screw holes on the exterior wall are not properly processed, it is easy to leak water. If waterproofing is required, water-stop screws must be used. The screws cannot be reused, which is very costly.

[0003] The existing Chinese patent with announcement number CN211817946U discloses a formwork structure for a cast-in-place plain concrete wall, including formwork panels arranged on the front and rear sides of the plain concrete wall to be cast, vertical back ribs pressed on the outside of the formwork panels, horizontal back ribs installed on the outside of the vertical back ribs, and waterstop bolts tied between the horizontal back ribs on both sides; when working, concrete is poured between the two formwork panels to form a plain concrete wall, and when the plain concrete wall is solidified, the part of the waterstop bolt located outside the plain concrete wall needs to be sawed off, and the middle part of the waterstop bolt remains inside the wall.

[0004] With respect to the above-mentioned related technologies, the inventor believes that two formworks are connected by waterstop bolts and then concrete is poured into the two formworks. However, the waterstop bolts cannot be reused and the cost is high. Summary of the invention

[0005] In order to save costs, the present application provides a large concrete wall formwork support device.

[0006] The present application provides a large concrete wall formwork support device adopts the following technical solution:

[0007] A large concrete wall formwork support device is used to support the formwork body. Two formwork bodies are arranged on both sides of the wall and are close to the wall. It includes a contact plate that presses against the side of the formwork body away from the wall. A counterweight block is connected to the contact plate. A lifting plate is connected to the contact plate. A lifting component for controlling the lifting of the lifting plate is connected to the lifting plate. A plurality of support members that contact the formwork body are installed on the side of the lifting plate close to the formwork body. A stabilizing rod is connected to the lower end of the contact plate. The stabilizing rod gradually shrinks to a pointed end in a direction away from the contact plate and is inserted into the ground.

[0008] By adopting the above technical scheme, when working, the two formwork bodies are pressed against the two sides of the wall, and then the device is moved until the contact plates respectively contact the side of the formwork body away from the wall, and the contact plates remain in a state of pressing against the formwork body under the action of the counterweight block; then the lifting assembly is started to control the lifting of the lifting plate, and the lifting of the lifting plate drives the lifting of the support member, so as to provide better support for formwork bodies of different heights. At the same time, the tip of the stabilizing rod is inserted into the ground so that the connection between the device and the ground is more stable, and further the effect of pressing against the formwork body is better; then concrete is poured between the two formwork bodies to form a concrete wall, so that when the concrete wall is solidified, it can be inferred that the device is separated from the formwork body, so that the device can be reused, which is convenient for saving costs.

[0009] Preferably, the contact plate is a hollow structure and is rotatably connected to a lead screw inside. The lifting plate is placed inside the contact plate and the upper end of the lifting plate passes through the upper surface of the contact plate. The lead screw is connected to a drive motor that drives the lead screw to rotate.

[0010] By adopting the above technical solution, when the driving motor is started, the driving motor drives the screw to rotate, and the rotation of the screw drives the lifting plate to rise and fall. The lifting of the lifting plate can provide better supporting force for the template body at different heights. The structure is simple and can achieve the required construction effect.

[0011] Preferably, the lead screw is a bidirectional lead screw, one end of the lead screw away from the lifting plate is threadedly connected to the stabilizing rod, and one end of the stabilizing rod away from the lifting plate passes through the abutment plate.

[0012] By adopting the above technical solution, when the lead screw rotates to drive the lifting plate to rise and fall, the lead screw can simultaneously drive the stabilizing rod to move in the direction away from the lifting plate, that is, the depth of the stabilizing rod inserted into the ground continues to increase; in this way, when the device supports a higher template body, the connection between the device and the ground is also more solid, reducing the occurrence of movement of the device when the lifting plate rises and supports the template body.

[0013] Preferably, a support plate is fixed to a side of the contact plate away from the template body, a first rod body is hinged to a side of the contact plate close to the support plate, a second rod body is hinged to the upper surface of the support plate, a sliding hole is provided on a side of the first rod body close to the second rod body, an end of the second rod body away from the support plate extends into the sliding hole and is slidably connected to the first rod body, and a locking assembly is connected to the first rod body for locking the first rod body and the second rod body by pressing against the second rod body.

[0014] By adopting the above technical solution, when the lifting plate is lifted or lowered, the first rod body and the second rod body move in the direction of approaching or moving away from each other. When the lifting plate is lifted or lowered to the required height, the first rod body and the second rod body are locked by the locking assembly. In this way, the first rod body and the second rod body can provide a certain supporting force for lifting plates of different heights, so that the lifting plate can be better pressed against the template body.

[0015] Preferably, the locking assembly includes an installation groove opened on an inner wall of the first rod body, a locking block is slidably connected in the installation groove and pressed against the side wall of the second rod body, a spring is fixed between the locking block and the bottom wall of the installation groove, and a grip rod passing through the side wall of the first rod body is fixed to a side of the locking block away from the second rod body.

[0016] By adopting the above technical solution, the locking block is pressed against the side wall of the second rod body under the action of the spring. In this way, when the first rod body and the second rod body need to move relative to each other more smoothly, the grip rod is pulled in a direction away from the first rod body, and the grip rod pulls the locking block out of contact with the second rod body. In this way, the first rod body and the second rod body can move relative to each other more smoothly, and the operation is simple and convenient.

[0017] Preferably, a side surface of the second rod body close to the installation groove is provided with a plurality of engaging grooves arranged along the length direction of the second rod body, and the locking block is engaged with one of the engaging grooves.

[0018] By adopting the above technical solution, when the locking block is engaged with one of the engaging grooves, the first rod body and the second rod body are relatively locked, so that the locking assembly has a better effect of locking the first rod body and the second rod body; when the first rod body and the second rod body need to be relatively slidable, the gripping rod can be pulled away from the first rod body to disengage the locking block from the engaging groove, and the operation is simple and convenient.

[0019] Preferably, a surface of the locking block away from the support plate is an inclined surface inclined downward in a direction away from the mounting groove.

[0020] By adopting the above technical solution, when the first rod body and the second rod body move in a direction away from each other, the upper edge of each engaging groove abuts against the inclined surface so that the locking block slides completely into the installation groove; when the movement of the first rod body and the second rod body is stopped, the locking block can be engaged with the engaging groove close to the locking block under the action of the spring, that is, the locking block can automatically lock the first rod body and the second rod body, which is more convenient.

[0021] Preferably, the support member is a roller.

[0022] By adopting the above technical solution, when the lifting plate drives the roller to lift, the roller rolls during the lifting process, which can reduce the resistance to the lifting of the lifting plate, thereby facilitating the lifting of the lifting plate.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. It is convenient to provide better support for the formwork bodies of different heights. At the same time, the tip of the stabilizing rod is inserted into the ground, so that the connection between the device and the ground is more stable. The device can be reused, which is convenient for saving costs.

[0025] 2. When the device supports a higher formwork body, the connection between the device and the ground becomes more solid, reducing the movement of the device when the lifting plate rises and supports the formwork body;

[0026] 3. The locking block can automatically lock the first rod body and the second rod body, which is more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] The embodiment of the present application discloses a large concrete wall formwork support device. Figure 1, which is used to support the formwork body 2, the formwork body 2 is arranged on both sides of the wall 1, the wall 1 includes a first wall 11 and a second wall 12, a cavity 13 is left between the first wall 11 and the second wall 12, the two formwork bodies 2 are respectively located on both sides of the cavity 13, and the large concrete wall formwork supporting device includes a support plate 3, and a side of the support plate 3 close to the formwork body 2 is fixedly connected with a resistance plate 4 arranged in the vertical direction, the resistance plate 4 resists and supports the formwork body 2, and a plurality of counterweight blocks 31 are placed on the upper surface of the support plate 3.

[0034] During operation, the formwork body 2 is placed on both sides of the cavity 13 respectively, and the formwork body 2 is made close to the wall 1. Then, the device is moved to the side of the formwork body 2 away from the wall 1, and the device is pushed toward the formwork body 2, so that the contact plate 4 contacts and supports the side of the formwork body 2 away from the wall 1, and then a number of counterweights 31 are placed on the upper surface of the support plate 3 as needed; at this time, the device completes the support of the formwork body 2, and then concrete is poured into the cavity 13 to form the concrete wall 1.

[0035] Reference Figure 2 and Figure 3 A sliding hole 41 is provided on the upper surface of the contact plate 4. The contact plate 4 is a hollow structure, and a lifting plate 5 is arranged inside the contact plate 4. The upper end of the lifting plate 5 extends out of the sliding hole 41. A lifting component 6 is connected to the lifting plate 5 to drive the lifting plate 5 to rise and fall. The lifting plate 5 can provide support to the template body 2 together with the contact plate 4, and the lifting plate 5 is lifted and lowered under the drive of the lifting component 6 to facilitate the support of the template body 2 at different heights.

[0036] Reference Figure 3 The lifting assembly 6 includes a horizontal support rod 61 fixedly connected inside the contact plate 4. The number of the support rods 61 is 2, and a lead screw 62 set in the vertical direction is rotatably connected to the support rod 61. The upper end of the lead screw 62 is inserted into the lifting plate 5 and is threadedly connected to the lifting plate 5. A bevel gear 63 is fixedly connected to the outer wall of the lead screw 62. A drive motor 64 is installed on the side of the contact plate 4 away from the template body 2. The output shaft of the drive motor 64 extends into the contact plate 4 and is also fixedly connected to the bevel gear 63. The two bevel gears 63 are meshed with each other. The drive motor 64 has forward and reverse rotation.

[0037] When the driving motor 64 is started, the output shaft of the driving motor 64 rotates to drive the bevel gear 63 to rotate, and the rotation of the bevel gear 63 drives the lead screw 62 to rotate. In this way, the rotation of the lead screw 62 can drive the lifting plate 5 to rise and fall, and the operation is simple and convenient.

[0038] A support member is installed on one side of the lifting plate 5 close to the template body 2, and the support member always contacts the template body 2 during the lifting and lowering process of the lifting plate 5, so that the lifting plate 5 can provide better support for the template body 2. The support member is a roller 51, and when the lifting plate 5 drives the roller 51 to rise and fall, the roller 51 is always in a state of contacting the template body 2, and the rolling of the roller 51 during the lifting and lowering process can reduce the resistance to the lifting and lowering of the lifting plate 5, which is convenient for the lifting and lowering of the lifting plate 5.

[0039] In order to reduce the possibility that the device moves away from the template body 2 under the force given by the template body 2 during the rising process of the lifting plate 5, the screw 62 is a bidirectional screw 62, and the lower end of the screw 62 is threadedly connected with a stabilizing rod 65. The end of the stabilizing rod 65 away from the lifting plate 5 penetrates the bottom wall of the resistance plate 4, and the stabilizing rod 65 gradually shrinks in the direction away from the lifting plate 5 to form a pointed end.

[0040] When the lead screw 62 rotates to make the lifting plate 5 rise, the lead screw 62 rotates to drive the stabilizing rod 65 to move away from the contact plate 4 and insert into the ground, so that the higher the lifting plate 5 rises, the deeper the stabilizing rod 65 is inserted into the ground. This reduces the movement of the device when the lifting plate 5 rises and supports the template body 2.

[0041] The ends of the lifting plate 5 and the stabilizing rod 65 that are close to each other are respectively fixedly connected to the limiting blocks 66 , and each limiting block 66 respectively limits the lifting plate 5 and the stabilizing rod 65 from being separated from the abutting plate 4 .

[0042] Reference Figure 3 and Figure 4 Two support mechanisms 7 for supporting the lifting plate 5 are provided on the side of the lifting plate 5 away from the template body 2, and the two support mechanisms 7 are respectively located near the two ends of the lifting plate 5. The support mechanism 7 includes a first rod 71 hinged to the side of the lifting plate 5 away from the template body 2, and also includes a second rod 72 hinged to the upper surface of the support plate 3. A sliding hole 711 is provided on the side of the first rod 71 close to the support plate 3, and an end of the second rod 72 away from the support plate 3 extends into the sliding hole 711 and is slidably connected to the first rod 71. The first rod 71 is connected to a locking assembly 8 for locking the first rod 71 and the second rod 72.

[0043] When the lifting plate 5 rises, the locking assembly 8 is loosened, and the first rod 71 and the second rod 72 move away from each other. When the lifting plate 5 rises to a desired position, the first rod 71 and the second rod 72 are locked by the locking assembly 8, so that the first rod 71 and the second rod 72 can give a certain supporting force to the lifting plate 5, so that the lifting plate 5 can better support the template body 2. Similarly, when the lifting plate 5 descends, the locking assembly 8 is loosened, and the first rod 71 and the second rod 72 move toward each other.

[0044] A plurality of engaging grooves 721 are formed on one side of the second rod body 72, and the plurality of engaging grooves 721 are arranged along the length direction of the second rod body 72. The locking assembly 8 includes a mounting groove 81 formed on an inner side wall of the first rod body 71 close to the engaging groove 721, a locking block 82 is slidably connected in the mounting groove 81, a spring 83 is provided between the locking block 82 and the bottom wall of the mounting groove 81, one end of the spring 83 is fixedly connected to the locking block 82, and the other end is fixedly connected to the bottom wall of the mounting groove 81.

[0045] When the spring 83 is in a normal state, one end of the locking block 82 is engaged with one of the engaging grooves 721, and the other end is placed in the mounting groove 81. A gripping rod 84 is fixedly connected to a side of the locking block 82 away from the engaging groove 721. The gripping rod 84 penetrates the side wall of the first rod body 71 and extends out of the first rod body 71. The upper surface of the locking block 82 is an inclined surface 85 that is inclined downward in a direction away from the mounting groove 81.

[0046] When the first rod 71 and the second rod 72 move away from each other, the upper edge of each engaging groove 721 contacts the inclined surface 85 and exerts a force on the locking block 82 to slide toward the mounting groove 81, so that the locking block 82 completely slides into the mounting groove 81. At this time, the spring 83 is in a compressed state, and the first rod 71 and the second rod 72 can smoothly move away from each other. When the movement of the first rod 71 and the second rod 72 is stopped, the locking block 82 can engage with the engaging groove 721 close to the locking block 82 under the force of the spring 83, that is, the locking block 82 can automatically lock the first rod 71 and the second rod 72, which is more convenient.

[0047] When the first rod body 71 and the second rod body 72 move in a direction toward each other, the grip rod 84 is pulled in a direction away from the first rod body 71, and the grip rod 84 drives the locking block 82 to slide completely into the installation groove 81. At this time, the first rod body 71 and the second rod body 72 can move smoothly in a direction away from each other; when the movement of the first rod body 71 and the second rod body 72 is stopped, the grip rod 84 is released, and the locking block 82 can be engaged with the engaging groove 721 close to the locking block 82 under the action of the spring 83.

[0048] The implementation principle of a large concrete wall formwork support device in the embodiment of the present application is as follows: two formwork bodies 2 are placed on both sides of the cavity 13, and the formwork bodies 2 are controlled to be close to the wall 1, and then the device is moved to be placed on the side of the formwork body 2 away from the wall 1. The device is pushed toward the formwork body 2 until the contact plate 4 is pressed against the formwork body 2, and then a number of counterweights 31 are placed on the support plate 3 according to needs.

[0049] The driving motor 64 is started, and the driving motor 64 drives the lead screw 62 to rotate so as to control the lifting plate 5 to rise. At the same time, the stabilizing rod 65 is inserted into the ground driven by the lead screw 62. When the lifting plate 5 rises to the required height, the driving motor 64 is turned off. In the process of the lifting plate 5 rising, the first rod body 71 and the second rod body 72 move away from each other. When the lifting plate 5 stops rising, the locking block 82 is clamped with one of the clamping grooves 721 under the action of the spring 83, so that the first rod body 71 and the second rod body 72 are locked. The first rod body 71 and the second rod body 72 can provide better support for the lifting plate 5, so that the lifting plate 5 can be pressed against the template body 2.

[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.
