Abstract
Description
Technical Field
[0001] This utility model relates to the field of template shaping and reinforcement, specifically a device for shaping and reinforcing curved wall templates. Background Technology
[0002] In construction engineering, wall formwork is a crucial preparatory step before concrete pouring, directly affecting the dimensional accuracy, verticality, and surface smoothness of the concrete. Wall formwork typically involves the design, fabrication, installation, and reinforcement of the formwork. Formwork materials often include film-coated plywood, while the framing uses a combination of square timber and steel pipes to provide sufficient strength and rigidity. The support system usually employs steel pipe scaffolding or specialized support frames, securely connecting the formwork to the support system using bolts, fasteners, and other connectors to ensure that the formwork does not deform or shift during concrete pouring.
[0003] During use and observation, it was found that when using existing technology to reinforce curved walls with formwork, the curvature of the curved wall changes, causing uneven deformation of the formwork under stress, which leads to bulging.
[0004] Therefore, a curved wall formwork shaping and reinforcement device is proposed to address the above problems. Utility Model Content
[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The arc-shaped wall template shaping and reinforcement device of this utility model includes three pairs of first templates, and multiple pairs of second templates are provided between adjacent pairs of first templates; each pair of first templates has a pair of back ribs on both sides; each pair of second templates has pressure plates on both sides; each pair of second templates has a channel steel on the top; the channel steel and the adjacent pair of pressure plates are connected by bolts; multiple tie rods are installed between each pair of pressure plates and each pair of back ribs; the tie rods and the second templates and back ribs are all through-type; by selecting steel second templates, the second templates can improve the forming quality and appearance quality of the arc-shaped wall. At the same time, through the connection and installation of pressure plates, channel steel, and tie rods, the second templates can be subjected to the stabilizing reinforcement effect applied by the pressure plates during installation, ensuring that the second templates can stably support the wall during pouring and reducing the bulging of the template during wall pouring.
[0007] Preferably, a plurality of lead screws are fixedly connected to the inner wall of the outer pressure plate; a sleeve is threadedly connected to the middle of the lead screw; a top plate is rotatably connected to the end of the sleeve; the inner wall of the top plate has an arc-shaped structure; through the cooperation of the sleeve and the top plate, when the pressure plate reinforces the second template, the top plate can be supported by rotating the sleeve, thereby increasing the contact area between the pressure plate and the second template and improving the stability of the pressure plate in reinforcing the second template.
[0008] Preferably, a groove is provided in the middle of the sleeve; the inner wall of the groove is multi-angled; by providing a groove on the surface of the sleeve, when the worker operates the sleeve, the sleeve can be rotated by a wrench or other tools to ensure that the sleeve and the top plate can apply sufficient compression force when pressing the second template.
[0009] Preferably, a filling pad is fixed to the end of the top plate; the filling pad is located between the pressure plate and the second template; by setting the filling pad, when the inner walls of the top plate and the second template come into contact, the filling pad will fill the gap between the top plate and the second template caused by the processing tolerance, thereby increasing the contact area between the top plate and the second template and improving the reinforcement effect of the device on the second template.
[0010] Preferably, an anchor cable is fixed between adjacent back ribs; the anchor cable is elastically configured; after the back ribs are installed, the two ends of the anchor cable can be fixed inside the back ribs by welding. After welding, the anchor cable will adapt to the wall at the second template and deform. At the same time, because the anchor cable is elastic, it will continuously squeeze the pressure plate under the elastic force, thereby increasing the squeezing effect of the pressure plate on the second template and further reducing the possibility of bulging during the pouring of the second template.
[0011] Preferably, multiple pairs of second templates are fixedly connected with sponge strips; the sponge strips are located at the bottom of the second templates; by setting the sponge strips, when the concrete on the inner wall of the second template is poured, the mortar passing through the gap between the second template and the bottom plate will be blocked by the sponge strips, reducing the leakage of mortar during the wall pouring.
[0012] The advantages of this utility model are:
[0013] 1. The curved wall formwork shaping and reinforcement device of this utility model improves the forming quality and appearance quality of the curved wall by using a steel second formwork. At the same time, through the connection and installation of pressure plate, channel steel and tie rod, the second formwork can be stabilized and reinforced by the pressure plate during installation, ensuring that the second formwork can stably support the wall during pouring and reducing the bulging of the formwork during the pouring of the wall.
[0014] 2. The arc-shaped wall template shaping and reinforcement device of this utility model, through the cooperation of the sleeve and the top plate, allows the top plate to support the second template when the pressure plate reinforces the second template, by rotating the sleeve, thereby increasing the contact area between the pressure plate and the second template and improving the stability of the pressure plate reinforcement of the second template.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0023] Specific implementation examples are given below.
[0024] Please see Figures 1 to 5As shown in the embodiment of this utility model, a curved wall template shaping and reinforcement device includes three pairs of first templates 1, with multiple pairs of second templates 13 between adjacent pairs of first templates 1; each pair of first templates 1 has a pair of back ribs 12 on both sides; each pair of second templates 13 has pressure plates 14 on both sides; each pair of second templates 13 has a channel steel 15 on the top; the channel steel 15 and the adjacent pair of pressure plates 14 are connected by bolts; multiple tie rods 16 are installed between each pair of pressure plates 14 and each pair of back ribs 12; the tie rods 16 and the second templates 13 and back ribs 12 are all through-type; during installation, the first templates 1 and second templates 13 can be installed on the base plate at the designed positions. The second templates 13 can be made of steel. The connections between adjacent second templates 13 and between the first templates 1 and second templates 13 can be assembled by bolts. The inner walls of the outermost first templates 1 and second templates 13 are flush with the edge of the base plate. After the main assembly is completed, the tie rods 16 can penetrate the first templates 1 and second templates 13 to connect the corresponding pressure plates 14 and back ribs 12. The back brace 12 is connected, so that the first template 1 and the second template 13 will be subjected to additional tie and support. The existing technology for the template reinforcement of the normal wall at the first template 1 and the use of tie rods 16 is very mature and will not be described in detail here. For the curved wall at the second template 13, the channel steel 15 can be erected on the top of the second template 13 to rigidly connect the adjacent pressure plate 14. Specifically, it can be connected and installed with bolts, so that the connection between the pair of pressure plates 14 is tighter, and the second template 13 can be more stably reinforced. This ensures that the second template 13 will not bulge during the pouring of the wall, so as to ensure that the cross-sectional dimensions of the wall meet the design requirements. By using a steel second template 13, the second template 13 can improve the forming quality and appearance quality of the curved wall. At the same time, through the connection and installation of pressure plate 14, channel steel 15 and tie rods 16, the second template 13 can be stably reinforced by the pressure plate 14 during installation, ensuring that the second template 13 can stably support the wall during the pouring of the wall and reduce the bulging of the wall during the pouring of the wall.
[0025] Please see Figure 4 and Figure 5As shown, multiple lead screws 2 are fixed to the inner wall of the outer pressure plate 14; a sleeve 22 is threadedly connected to the middle of the lead screw 2; a top plate 23 is rotatably connected to the end of the sleeve 22; the inner wall of the top plate 23 has an arc-shaped structure; after a pair of pressure plates 14 are connected by the pull screws 16, the sleeve 22 can be rotated to slide along the lead screws 2, and the sleeve 22 will move together with the top plate 23 towards the inner wall of the second template 13. During the process, the inner wall of the top plate 23 can be aligned by rotating the top plate 23. The inner wall of the second template 13 extends to the top plate 23, which abuts against the inner wall of the second template 13, thereby increasing the pressing area of the pressure plate 14 on the second template 13 and improving the reinforcement effect of the pressure plate 14 on the second template 13. Through the cooperation of the sleeve 22 and the top plate 23, when the pressure plate 14 reinforces the second template 13, the top plate 23 can be supported by rotating the sleeve 22, increasing the contact area between the pressure plate 14 and the second template 13 and improving the stability of the reinforcement of the second template 13 by the pressure plate 14.
[0026] Please see Figure 5 As shown, a groove 3 is provided in the middle of the sleeve 22; the inner wall of the groove 3 is multi-angled; by providing a groove 3 on the surface of the sleeve 22, when the worker operates the sleeve 22, the sleeve 22 can be rotated by a wrench or other tools to ensure that the sleeve 22 and the top plate 23 can apply sufficient squeezing force when squeezing the second template 13.
[0027] Please see Figure 5 As shown, a filling pad 4 is fixedly connected to the end of the top plate 23; the filling pad 4 is located between the pressure plate 14 and the second template 13; by setting the filling pad 4, when the inner walls of the top plate 23 and the second template 13 come into contact, the filling pad 4 will fill the gap between the top plate 23 and the second template 13 caused by the processing tolerance, thereby increasing the contact area between the top plate 23 and the second template 13 and improving the reinforcement effect of the device on the second template 13.
[0028] Please see Figure 1 and Figure 2 As shown, anchor cables 5 are fixed between adjacent back ribs 12; the anchor cables 5 are elastically configured; after the back ribs 12 are installed, the two ends of the anchor cables 5 can be fixed inside the back ribs 12 by welding and prestressing is applied. After welding, the anchor cables 5 will adapt to the wall at the second template 13 to deform. At the same time, because the anchor cables 5 are elastic, they will continuously squeeze the pressure plate 14 under the action of elastic force, thereby increasing the squeezing effect of the pressure plate 14 on the second template 13, further reducing the possibility of bulging during the pouring of the second template 13.
[0029] Please see Figure 3As shown, multiple pairs of second templates 13 are fixedly connected with sponge strips 6; the sponge strips 6 are located at the bottom of the second templates 13; by setting the sponge strips 6, when the concrete of the inner wall of the second template 13 is poured, the mortar passing through the gap between the second template 13 and the bottom plate will be blocked by the sponge strips 6, reducing the leakage of mortar during the pouring of the wall.
[0030] Working principle: The first template 1 and the second template 13 are installed at their designed positions on the base plate. The second template 13 can be made of steel. Adjacent second templates 13 and the connections between the first template 1 and the second template 13 can be assembled using bolts. The inner walls of the outermost first template 1 and the second template 13 are flush with the edge of the base plate. After the main assembly is completed, tie rods 16 can be used to connect the corresponding pressure plates 14 and back ribs 12 through the first template 1 and the second template 13, so that the first template 1 and the second template 13 will receive additional tension and support. For the reinforcement of the normal wall at the first template 1 and the use of tie rods 16, the existing technology is already very advanced. The details of the process are not elaborated here. Regarding the curved wall at the second formwork 13, a channel steel 15 can be installed on top of the second formwork 13 to rigidly connect the adjacent pressure plates 14. Specifically, this can be achieved through bolt connection, resulting in a tighter connection between the pair of pressure plates 14 and providing more stable reinforcement to the second formwork 13. This ensures that the second formwork 13 will not bulge during pouring, guaranteeing that the wall's cross-sectional dimensions meet design requirements. After connecting the pair of pressure plates 14 using the tie rod 16, the sleeve 22 can be rotated to slide along the threaded rod 2. The sleeve 22 will move along with the top plate 23 towards the inner wall of the second formwork 13. During this process, [further details can be added]. By rotating the top plate 23, the inner wall of the top plate 23 is aligned with the inner wall of the second template 13 until the top plate 23 can abut against the inner wall of the second template 13. This increases the pressing area of the pressure plate 14 on the second template 13, improving the reinforcement effect of the pressure plate 14 on the second template 13. A groove 3 is provided on the surface of the sleeve 22, allowing workers to rotate the sleeve 22 using a wrench or other tools, ensuring sufficient pressing force is applied when the sleeve 22 and the top plate 23 press against the second template 13. A filling pad 4 is provided so that when the top plate 23 and the inner wall of the second template 13 come into contact, the filling pad 4 will fill any gaps caused by machining tolerances between the top plate 23 and the second template 13. The gaps are filled to increase the contact area between the top plate 23 and the second template 13, thereby improving the reinforcement effect of the device on the second template 13. After the back rib 12 is installed, the two ends of the anchor cable 5 can be fixed inside the back rib 12 by welding and prestressing is applied. After the anchor cable 5 is welded, it will adapt to the wall at the second template 13 and deform. At the same time, because the anchor cable 5 is elastic, it will continuously squeeze the pressure plate 14 under the elastic force, thereby increasing the squeezing effect of the pressure plate 14 on the second template 13. By setting the sponge strip 6, when the concrete on the inner wall of the second template 13 is poured, the mortar passing through the gap between the second template 13 and the bottom plate will be blocked by the sponge strip 6.
[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
