Description

Technical Field

[0001] This utility model relates to the technical field of sealing and leak-proofing tools for concrete pouring formwork joints, and in particular to a sealing and leak-proofing adjustment device for concrete pouring formwork joints. Background Technology

[0002] In concrete pouring construction, formwork serves as the core carrier for concrete forming, and its splicing quality directly determines the appearance accuracy and structural strength of concrete components. Formwork joints are the weakest link in the formwork system. Due to formwork processing errors, joint width deviations during installation, impact loads during pouring, and the lateral pressure of concrete, grout leakage is highly likely to occur at the joints.

[0003] Traditional concrete casting formwork joint structures have significant limitations in adapting to the width and depth of different types of fixing slots. They can only match a single specification of fixing slot and lack effective elastic compensation design. They cannot cope with dimensional deviations caused by the formwork's own weight and construction collisions during installation, and gaps are easily formed at the contact points. Their limiting methods are mostly single-point or few-contact designs, with a simple anti-sway restraint mechanism and high sliding friction resistance. They are unable to resist the internal angle offset and lateral displacement of the formwork under the impact load of pouring, resulting in weak structural stability at the joint. At the same time, these structural defects can easily cause the seals to detach from the formwork surface, thereby increasing the risk of grout leakage. Ultimately, this may lead to appearance and strength defects such as honeycomb, pitting, and exposed reinforcement in the concrete components, affecting construction quality and the progress of subsequent processes. Utility Model Content

[0004] The purpose of this utility model is to provide a sealing and leak-proof adjustment device for concrete pouring formwork joints. Through the coordinated operation of springs and pulleys, utilizing the elastic compensation effect of the springs and the sliding characteristics of the pulleys, the pre-compressed springs are fitted onto the surface of the installation column. This allows for adaptive elastic deformation according to the structural differences of the fixing groove. Combined with the rolling friction characteristics between the pulleys and the inner wall of the fixing groove, it can not only flexibly adapt to differences in groove width and depth of different models of fixing grooves, but also compensate for the formwork's own weight during installation in real time. Simultaneously, the configuration of eight pulley groups forms multi-point contact and limiting, significantly improving the constraint on formwork swaying, further enhancing the structural stability of the joints, and providing a more reliable guarantee for the sealing and leak-proof effect.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a sealing and leak-proof adjustment device for concrete pouring formwork joints, comprising: Main body, concrete block; The anti-sway assembly includes a fixing groove fixedly installed on the upper end of the concrete block surface, a slider locked in the inner cavity of the fixing groove, a mounting post fixedly installed on the upper and lower surfaces of the slider, a spring sleeved on the surface of the mounting post, a mounting seat fixedly installed on the front end of the mounting post surface, a rotating shaft fixedly sleeved on both ends of the mounting seat, a pulley sleeved on the surface of the rotating shaft, a limiting baffle fixedly installed on the front end of the slider surface, a fixing base fixedly installed on the top end of the slider surface, a hole opened on the surface of the fixing base, a first bolt penetrating inside the hole, an L-shaped mounting arm fixedly installed on the top end of the fixing base surface, a pressure plate fixedly installed on the top end of the L-shaped mounting arm surface, and a pressure strip placed on the top end of the pressure plate surface.

[0006] Furthermore, the fixing groove extends and is fixed along the length of the template joint at the upper end of the concrete block surface, and the slider is locked in the inner cavity of each fixing groove, with two sliders in each fixing groove.

[0007] Specifically, the fixing groove provides the slider with an installation reference and linear guide channel along the joint direction, ensuring that the slider's movement trajectory is consistent with the joint direction; the two sliders set in each fixing groove form multi-point support through distributed arrangement along the length of the fixing groove, which, together with other components of the anti-sway assembly, achieves balanced limiting at the template joint.

[0008] Furthermore, there are a total of eight mounting posts, which are fixed to the upper and lower surfaces of the slider in two groups. The four mounting posts on the upper surface of the slider are evenly distributed and symmetrically arranged along the length of the slider, while the four mounting posts on the lower surface of the slider are arranged coaxially with the corresponding mounting posts on the upper surface. Specifically, the eight mounting columns are arranged in a symmetrical pattern of four groups on each side. The coaxial layout and uniform symmetry of the upper surface provide a stable and balanced mounting carrier for the spring, mounting base and pulley. The distributed arrangement on the upper and lower surfaces ensures that the force of the anti-sway component is evenly distributed along the vertical direction of the slider, avoiding localized force concentration.

[0009] Furthermore, the fixing base is vertically fixed at the center of the upper surface of the slider, and the length of the fixing base is the same as the length of the slider; the hole extends through the thickness of the fixing base.

[0010] Specifically, the fixed base provides a centered and stable mounting reference for the L-shaped mounting arm and the first bolt, ensuring accurate assembly of subsequent components and uniform transmission of force along the central axis of the slider, avoiding local force deviation.

[0011] Furthermore, the first bolt corresponds one-to-one with the hole, the diameter of the first bolt's shank matches the inner diameter of the hole, and the head diameter of the first bolt is larger than the inner diameter of the hole.

[0012] Specifically, the first bolt is set to correspond one-to-one with the hole to ensure the coaxiality and fit of the bolt during installation and to avoid wobbling gaps; the diameter of the first bolt head is larger than the inner diameter of the hole, which can form an axial limiting and clamping effect after the bolt is tightened to prevent the bolt from falling out of the hole.

[0013] Furthermore, the concrete pouring formwork joint sealing and leak prevention adjustment device also includes a leak-connecting component, which includes a mounting base fixedly welded to both ends of the pressure plate, a second bolt penetrating inside the mounting base, a nut screwed into the middle of the second bolt, a drain plate screwed into the top of the surface of the second bolt, a screw hole opened at the top of the surface of the drain plate, and a drain groove opened at the lower end of the surface of the drain plate.

[0014] Furthermore, the leakage collection assembly also includes a hook for fixing the side of the drainage plate, a collection trough set on the side of the concrete block surface, and a hook fixedly welded to the top of the collection trough surface.

[0015] Specifically, the hook is fixedly installed on the side surface of the diversion plate to provide a connection support point for the collection tank; the collection tank is used to receive the seepage slurry diverted by the diversion tank; the hook is adapted to the hook, and the collection tank can be quickly positioned and fixed by the hook and the hook fastening connection.

[0016] Furthermore, one mounting base is fixedly welded to each end of each pressure plate along its length. The mounting base is set to fit against the end face of the pressure plate, and its axis is parallel to the vertical direction of the pressure plate.

[0017] Specifically, the mounting base provides symmetrical and stable mounting support points for the second bolt, ensuring that the second bolt is assembled in the vertical direction, avoiding installation offset from affecting the height adjustment accuracy of the diversion plate, and the symmetrical layout at both ends ensures that the pressure plate is subjected to balanced force, thus ensuring the overall assembly stability of the leakage connection component.

[0018] Compared with existing technologies, the advantages of this utility model are: The purpose of this utility model is to provide a sealing and leak-proof adjustment device for concrete pouring formwork joints. Through the coordinated operation of springs and pulleys, utilizing the elastic compensation effect of the springs and the sliding characteristics of the pulleys, the pre-compressed springs are fitted onto the surface of the installation column. This allows for adaptive elastic deformation according to the structural differences of the fixing groove. Combined with the rolling friction characteristics between the pulleys and the inner wall of the fixing groove, it can not only flexibly adapt to differences in groove width and depth of different models of fixing grooves, but also compensate for the formwork's own weight during installation in real time. Simultaneously, the configuration of eight pulley groups forms multi-point contact and limiting, significantly improving the constraint on formwork swaying, further enhancing the structural stability of the joints, and providing a more reliable guarantee for the sealing and leak-proof effect.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0024] Please see Figure 1-4 As shown, this embodiment is a sealing and leak-proof adjustment device for concrete pouring formwork joints, comprising: Main body, concrete block 11; In practical use, the concrete block 11 is the core forming object of the pouring construction, and the device is assembled on its surface.

[0025] The anti-sway assembly includes a fixing groove 21 fixedly installed on the upper surface of the concrete block 11, a slider 22 locked in the cavity of the fixing groove 21, a mounting post 23 fixedly installed on the upper and lower surfaces of the slider 22, a spring 24 sleeved on the surface of the mounting post 23, a mounting seat 25 fixedly installed on the front end of the surface of the mounting post 23, a rotating shaft 26 fixedly sleeved on both ends of the mounting seat 25, a pulley 27 sleeved on the surface of the rotating shaft 26, a limiting baffle 28 fixedly installed on the front end of the surface of the slider 22, a fixing base 29 fixedly installed on the top surface of the surface of the slider 22, a hole 210 opened on the surface of the fixing base 29, a first bolt 211 penetrating inside the hole 210, an L-shaped mounting arm 212 fixedly installed on the top surface of the surface of the fixing base 29, a pressure plate 213 fixedly installed on the top surface of the L-shaped mounting arm 212, and a pressure strip 214 placed on the top surface of the pressure plate 213.

[0026] In practical use, the fixing groove 21 is first fixedly installed on the upper surface of the concrete block 11, and then the slider 22 is locked in the inner cavity of the fixing groove 21 so that it can slide along the length of the groove. Then, the mounting column 23 is fixedly installed on the upper and lower surfaces of the slider 22, the spring 24 is sleeved on the surface of the mounting column 23, and the mounting seat 25 is fixedly installed on the front end of the surface of the mounting column 23 and fits against the front end of the spring 24. At the same time, the limiting baffle 28 is fixedly installed on the front end of the surface of the slider 22. The first bolt 211 is tightened, and the limiting baffle 28 abuts against the inner wall of the fixing groove 21 to achieve the fastening of the fixing base 29 and the template. The L-shaped mounting arm 212 is fixedly installed on the top of the surface of the fixing base 29, and the pressure plate 213 is fixedly installed on the top of the surface of the L-shaped mounting arm 212. Finally, the pressure strip 214 is placed on the top of the surface of the pressure plate 213 to complete the overall assembly.

[0027] Furthermore, in the existing device, the pressure plate 213 and the pressure strip 214 can only achieve the function of pressing the joint of the template. The pressing structure and the grout collection function are independent of each other and lack integrated design. Moreover, the existing collection components are mostly set up independently and need to be installed and positioned separately after the pressing operation is completed. This is not only cumbersome to install and disassemble and inconvenient to use, but also cannot be synchronized with the pressing action. During the process of pressing the template with the pressure plate 213, due to factors such as poor joint sealing and changes in pouring pressure, concrete grout inevitably leaks from the joint. Such independent collection structures often cannot respond quickly to grout leakage, resulting in the leakage of grout that cannot be collected in time. This not only wastes cement materials, but also contaminates the surface of the concrete block 11 and the construction base, increases the subsequent cleaning process, and may even affect subsequent construction operations due to grout solidification.

[0028] Specifically, it also includes a leakage connection component, which includes a mounting base 31 fixedly welded to the pressure plate 213 at both ends of the surface, a second bolt 32 penetrating inside the mounting base 31, a nut 33 screwed into the middle of the second bolt 32, a drain plate 35 screwed into the top of the surface of the second bolt 32, a screw hole 34 opened at the top of the surface of the drain plate 35, and a drain groove 36 opened at the lower end of the surface of the drain plate 35.

[0029] In practical use, the staff first welds the mounting base 31 to both ends of the pressure plate 213, then inserts the second bolt 32 vertically through the mounting base 31, and then screws the nut 33 into the middle of the second bolt 32. The diversion plate 35 is then screwed into the top of the surface of the second bolt 32 through the screw hole 34, so that the diversion plate 35 and the second bolt 32 form a threaded linkage. Tightening the nut 33 can adjust the installation height of the diversion plate 35 and lock it. Then, the device is assembled by fastening it to the hook 37 through the hook 38 on the collection groove 39.

[0030] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
