Description

Technical Field

[0001] This utility model relates to the field of building waterproofing construction technology, specifically to a fixing fixture for embedded waterstop strips. Background Technology

[0002] To enhance the waterproofing effect at construction joints in concrete structures, most projects currently use embedded waterstops for waterproofing. However, since the waterstops are in an unsupported state at the construction joints, they are prone to displacement and deformation during concrete pouring and vibration, which severely affects the waterproofing effect at the construction joints. At the same time, most existing waterstop fixing methods require steel bars as fixing materials, and the steel bars cannot be recycled after fixing, resulting in material waste.

[0003] Chinese Patent Publication No. CN223410304U discloses a waterstop fixing device, including a centering component, a clamping component, and a connecting component. This device connects the centering component and the clamping component via the connecting component, ensuring precise centering and clamping of the waterstop, ensuring straightness and preventing height deviation during installation, and enhancing the waterstop effect. The first adjusting member of the centering component can be adjusted along the length of the horizontal bar to adapt to different wall thicknesses and achieve precise centering. Simultaneously, the first fastener is connected to the horizontal reinforcement of the wall to ensure the stability of the horizontal bar. The clamping component symmetrically clamps the waterstop, applying a uniform clamping force to the clamping plate, reducing the risk of waterstop displacement due to vibration or stress. The second adjusting member is telescopic and can be adjusted according to the wall thickness to ensure the clamping plate firmly clamps the waterstop. This device has the advantages of precise positioning, simple operation, flexible adaptability, and low cost, and is suitable for use on walls of different specifications. The above device achieves connection and fixation through the centering component, clamping component, and connecting component, and requires the use of the horizontal reinforcement of the wall for final fixation. Therefore, it is imperative for those skilled in the art to solve the aforementioned technical problems. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the existing technology and improve the steering flexibility and service life of hydraulic plate compactors.

[0005] The technical solutions adopted in this utility model are as follows: A fixture for fixing an embedded waterstop includes a clamping plate, an upper fixing steel plate, rivets, bolt connection holes, connecting bolts, positioning holes, an upper positioning rod, and adjusting threads. The upper fixing steel plate is fixedly connected to the upper part of the clamping plate by rivets. Bolt connection holes are provided at both ends of the upper fixing steel plate, and the connecting bolts pass through the bolt connection holes of the upper fixing steel plates on both sides to connect the clamping plates laterally. A positioning hole is provided in the middle of the upper fixing steel plate, and the upper positioning rod passes through the positioning hole. The adjusting threads are provided on the outer wall of the upper positioning rod and are threadedly connected to the upper fixing steel plate.

[0006] By adopting the above technical solution, the upper fixed steel plate is fixedly connected to the upper part of the clamping plate by rivets, ensuring that the steel plate and the clamping plate form a rigid whole and avoiding relative displacement; the steel plates on both sides are tightened laterally by bolt connection holes and connecting bolts, which can form a stable clamping force on the waterstop and prevent the waterstop from shifting during pouring; the upper positioning rod passes through the positioning hole and is threaded to the steel plate through the adjusting thread, which can not only adjust the height of the positioning rod to adapt to waterstops of different thicknesses through the thread, but also maintain the positioning accuracy by taking advantage of the self-locking characteristic of the thread, so as to achieve precise fixation of the vertical position of the waterstop.

[0007] Furthermore, it also includes a self-locking washer, which is sleeved on the threaded rod of the connecting bolt and located between the upper fixing steel plate and the nut of the connecting bolt.

[0008] By adopting the above technical solution, the self-locking washer is sleeved on the threaded rod of the connecting bolt and located between the upper fixed steel plate and the nut. The elastic deformation and friction of the washer increase the anti-loosening effect of the bolt connection, which can effectively resist the vibration load generated by concrete pouring and vibration, avoid the decrease in clamping force caused by bolt loosening, and ensure that the tooling maintains a stable connection throughout the construction process.

[0009] Furthermore, the diameter of the positioning hole is slightly larger than the outer diameter of the upper positioning rod, and the axis of the upper positioning rod is collinear with the axis of the positioning hole.

[0010] By adopting the above technical solution, the diameter of the positioning hole is slightly larger than the outer diameter of the upper positioning rod, and the axes of the two are collinear. This provides the positioning rod with room for error during installation, avoiding assembly jamming due to processing errors. The collinearity of the axes also ensures the verticality of the positioning rod, preventing the positioning rod from tilting and causing the waterstop to deviate. At the same time, it facilitates the smooth adjustment of the height of the positioning rod in the hole.

[0011] Furthermore, it also includes an inner bolt hole and a lower positioning rod, wherein the inner bolt hole is opened in the middle of the clamping plate, and the lower positioning rod is vertically inserted into the inner bolt hole.

[0012] By adopting the above technical solution, an inner bolt hole is opened in the middle of the clamping plate, and the lower positioning rod is vertically inserted into the hole, so that the positioning rod forms a vertical support from below the clamping plate. Together with the upper positioning rod, it forms a double positioning structure, which enhances the longitudinal constraint on the waterstop, avoids tooling deformation caused by excessive force on a single positioning point, and improves the deformation resistance of the overall structure.

[0013] Furthermore, it also includes an adjusting block, which is sleeved on the outer wall of the lower positioning rod and matches the adjusting threads on the lower positioning rod.

[0014] By adopting the above technical solution, the adjusting block is sleeved on the outer wall of the lower positioning rod and matches the adjusting thread. By rotating the adjusting block, it can move along the axial direction of the positioning rod, which can both push the clamping plate upward to compensate for the installation gap and press the bottom of the waterstop downward to achieve bidirectional fixation of the waterstop in the vertical direction, further restricting its vertical movement during the pouring process.

[0015] Furthermore, it also includes a fixing block, which is fixedly sleeved on the lower end of the lower positioning rod, and its upper surface abuts against the lower surface of the clamping plate.

[0016] By adopting the above technical solution, the fixing block is fixedly sleeved on the lower end of the lower positioning rod and its upper surface abuts against the lower surface of the clamping plate. Through the rigid contact between the fixing block and the clamping plate, the axial displacement of the lower positioning rod is restricted, preventing the positioning rod from coming out of the inner bolt hole due to vibration or external force. At the same time, it provides stable support for the lower positioning rod, ensuring that it always maintains its vertical positioning function.

[0017] This utility model has the following beneficial effects: 1. This utility model forms a stable clamping structure by using the rivet rigid connection between the upper fixed steel plate and the clamping plate and the lateral tightening of the connecting bolts on both sides. It can apply a continuous and stable clamping force to the waterstop, effectively preventing the waterstop from shifting and deforming during the concrete pouring process. 2. This utility model enhances the anti-loosening effect of bolt connections by setting self-locking washers at the connecting bolts, utilizing the elastic deformation and friction of the washers. It can resist vibration loads and avoid the decrease in clamping force caused by bolt loosening, thus ensuring the connection stability of the tooling throughout the construction process. 3. This utility model, through the collinear design of the positioning hole and the upper positioning rod and the matching relationship of the hole diameter, not only provides error tolerance space for the installation of the positioning rod to avoid jamming caused by processing errors, but also ensures the verticality of the positioning rod. At the same time, the height can be adjusted by adjusting the threads, which improves the adaptability to waterstops of different thicknesses. 4. This utility model utilizes the dual positioning structure of upper and lower positioning rods and the synergistic effect of adjusting blocks and fixing blocks. The lower positioning rod forms a vertical support from below the clamping plate, the adjusting block can compensate for the gap in both directions and press the bottom of the waterstop, and the fixing block restricts the axial displacement of the positioning rod. Together, they enhance the longitudinal constraint, avoid deformation of a single positioning point, and improve the overall deformation resistance. Attached Figure Description

[0022] Reference Figure 1 , Figure 2 and Figure 3As can be seen, the present invention provides a fixing fixture for an embedded waterstop. The clamping plates 1, which serve as the basic load-bearing structure, are symmetrically distributed on both sides of the waterstop. The upper part of the clamping plates 1 is rigidly connected to the upper fixing steel plate 2 by rivets 3. The rivets 3 are spaced along the length of the clamping plates 1 to ensure that there is no relative displacement between the upper fixing steel plate 2 and the clamping plates 1, thus forming the main clamping frame. The upper fixing steel plate 2 has bolt connection holes 4 symmetrically opened at both ends. The connecting bolts 5 pass through the corresponding bolt connection holes 4 of the clamping plates 1 on both sides. The waterstop is clamped laterally by tightening the nuts on both sides of the clamping plates 1. A self-locking washer 6 is fitted on the thread of the connecting bolt 5. The washer is located between the upper fixing steel plate 2 and the nut of the connecting bolt 5. The elastic deformation of the washer fills the gap and increases the friction to prevent the bolt from loosening. A positioning hole 7 is provided in the middle of the upper fixed steel plate 2. The upper positioning rod 8 is vertically inserted into the positioning hole 7. The diameter of the positioning hole 7 is slightly larger than the outer diameter of the upper positioning rod 8, and the axes of the two are collinear. This provides the positioning rod with assembly tolerance space and ensures its verticality. The outer wall of the upper positioning rod 8 is machined with an adjusting thread 9. This thread is engaged with the internal thread around the positioning hole 7 on the upper fixed steel plate 2. By rotating the upper positioning rod 8, its extension length can be adjusted vertically to accommodate waterstops of different thicknesses. The clamping plate 1 has an inner bolt hole 10 in the middle. The lower positioning rod 11 is vertically inserted into the inner bolt hole 10 from bottom to top, forming a symmetrical double positioning structure with the upper positioning rod 8, which together restricts the longitudinal displacement of the waterstop. The outer wall of the lower positioning rod 11 is also provided with an adjusting thread 9. The adjusting block 12 is sleeved on the outer wall of the lower positioning rod 11 and threadedly connected to the adjusting thread 9. By rotating the adjusting block 12, it can move axially along the lower positioning rod 11. It can press against the lower surface of the clamping plate 1 to compensate for the installation gap, and press against the bottom of the waterstop to achieve bidirectional fixation. The lower end of the lower positioning rod 11 is fixedly sleeved with a fixing block 13. The upper surface of the fixing block 13 is in close contact with the lower surface of the clamping plate 1. The rigid contact restricts the axial movement of the positioning rod and prevents it from coming out of the inner bolt hole 10. At the same time, it provides stable support for the lower positioning rod 11 and ensures that it always maintains its vertical positioning function. The components form a coordinated whole structure through the above assembly relationship, achieving precise positioning and stable clamping of the waterstop.

[0023] In one embodiment, refer to Figure 3It can be seen that the two clamping plates 1 are symmetrically placed on both sides of the waterstop installation position, ensuring that the length direction of the clamping plates 1 is consistent with the extension direction of the waterstop. At the same time, check the integrity and dimensional compatibility of the components such as the upper fixing steel plate 2, rivets 3, connecting bolts 5, self-locking washers 6, upper positioning rods 8, and lower positioning rods 11. Then, the upper fixing steel plate 2 is fixedly connected to the upper part of each clamping plate 1 by rivets 3. The rivets 3 are drilled and riveted at intervals along the length direction of the clamping plate 1 to ensure that the upper fixing steel plate 2 and the clamping plate 1 are tightly fitted and without looseness, forming an overall clamping frame. Next, at both ends of the upper fixed steel plate 2 on both sides of the clamping plate 1, the connecting bolts 5 are passed laterally through the corresponding bolt connection holes 4, and self-locking washers 6 are fitted on the threads of the connecting bolts 5, so that the washers are located between the upper fixed steel plate 2 and the nuts of the connecting bolts 5. Then the nuts are tightened, and the clamping plate 1 initially clamps the waterstop through the tension of the connecting bolts 5 on both sides. During this process, the self-locking washers 6 fill the gap through elastic deformation, enhancing the anti-loosening effect of the bolt connection. After completing the lateral clamping, the upper positioning adjustment is performed: the upper positioning rod 8 is vertically inserted into the positioning hole 7 in the middle of the upper fixed steel plate 2. Since the diameter of the positioning hole 7 is slightly larger than the outer diameter of the upper positioning rod 8 and the two axes are collinear, it can be inserted smoothly; the upper positioning rod 8 is rotated, and the extension height of the upper positioning rod 8 is adjusted by using the adjusting thread 9 on its outer wall to engage with the thread of the upper fixed steel plate 2, so that its lower end presses against the upper surface of the waterstop, thereby achieving vertical positioning. Next, the lower-level positioning assembly is performed: A lower-level positioning rod 11 is vertically inserted from bottom to top into the inner bolt hole 10 in the middle of the clamping plate 1, forming a support from below the clamping plate 1. An adjusting block 12 is fitted onto the outer wall of the lower-level positioning rod 11. By rotating the adjusting block 12, it moves axially along the adjusting thread 9 on the lower-level positioning rod 11, pressing upwards against the lower surface of the clamping plate 1 to compensate for installation gaps, and downwards pressing against the bottom of the waterstop, achieving bidirectional fixation of the waterstop. Finally, a fixing block 13 is fixedly fitted onto the lower end of the lower-level positioning rod 11, ensuring that the upper surface of the fixing block 13 is in close contact with the lower surface of the clamping plate 1. This rigid contact restricts the axial displacement of the positioning rod, preventing it from coming out of the inner bolt hole 10. After installation, all connections are checked again for tightness. The positions of the upper-level positioning rod 8 and the adjusting block 12 are adjusted to ensure the waterstop is in a precise position under the lateral clamping force and vertical positioning action, allowing subsequent concrete pouring operations to proceed.

[0024] Working Principle: The device uses symmetrically distributed clamping plates 1 as the basic load-bearing structure. First, the main frame is constructed through a rigid connection between the upper fixed steel plate 2 and the clamping plates 1. The upper fixed steel plate 2 is riveted along the upper part of the clamping plates 1 at intervals using rivets 3, forming an integral structure without relative displacement, avoiding the loosening problems easily caused by traditional welding or bolt connections. The clamping plates 1 on both sides are laterally tightened by bolts 5 through bolt connection holes 4 at both ends of the upper fixed steel plate 2. The axial tension of the bolts creates a continuous and stable lateral clamping force on the waterstop, solving the problem of insufficient clamping force in traditional tooling, which easily leads to lateral displacement of the waterstop during concrete pouring and vibration. To further enhance clamping stability, a self-locking washer 6 is fitted on the thread of the connecting bolt 5. This washer is located between the upper fixed steel plate 2 and the nut, and through elastic deformation, it fills the thread gap and increases friction, effectively resisting the vibration load generated by vibration, avoiding the attenuation of clamping force due to bolt loosening, and overcoming the defects of poor vibration resistance and easy bolt loosening in traditional devices. In terms of vertical positioning, the device achieves precise adjustment through the cooperation of the upper positioning rod 8 and the positioning hole 7. The diameter of the positioning hole 7 opened in the middle of the upper fixed steel plate 2 is slightly larger than the outer diameter of the upper positioning rod 8, and the two axes are collinear. This provides a margin of error for the installation of the positioning rod to avoid assembly jamming caused by processing errors, and also ensures the verticality of the positioning rod, preventing the positioning tilting problem caused by the traditional single positioning hole and positioning rod being too tight or too loose. The adjusting thread 9 on the outer wall of the upper positioning rod 8 is engaged with the internal thread of the upper fixed steel plate 2. By rotating the positioning rod, the extension length can be adjusted vertically to adapt to waterstops of different thicknesses, solving the limitation of traditional tooling that cannot flexibly adapt to waterstops of various specifications. To enhance longitudinal restraint, the device innovatively adopts a dual-positioning structure: an inner bolt hole 10 is opened in the middle of the clamping plate 1, and the lower positioning rod 11 is inserted into the hole from bottom to top, forming a symmetrically distributed longitudinal positioning system with the upper positioning rod 8, which together restricts the vertical movement of the waterstop and avoids the deformation of the tooling caused by excessive force on the traditional single positioning point; the outer wall of the lower positioning rod 11 is also equipped with adjusting threads 9, and the fitted adjusting block 12 can move along the axial direction of the threads, pressing upward against the lower surface of the clamping plate 1 to compensate for the installation gap, and pressing downward against the bottom of the waterstop to achieve bidirectional fixation, which solves the problem that the traditional positioning structure can only limit movement in one direction and is prone to gaps that cause the waterstop to shift; the fixing block 13 at the lower end of the lower positioning rod 11 restricts the axial movement of the positioning rod by rigidly abutting against the lower surface of the clamping plate 1, preventing it from coming out of the inner bolt hole 10, and ensuring the stability of the positioning function throughout the construction process.
