Description

Technical Field

[0001] This invention belongs to the field of waterstop technology, specifically a waterstop anti-deformation fixing structure. Background Technology

[0002] Embedded rubber waterstops are generally made of natural rubber and various synthetic rubbers. They are primarily used as waterstops installed inside concrete structures such as expansion joints and deformation joints. They utilize the elasticity of the rubber material and their structural form to adapt to the expansion and contraction of the concrete. By leveraging the high elasticity and compressive deformation properties of rubber, they produce elastic deformation under various loads, effectively preventing water leakage and seepage in building components, and also providing shock absorption and cushioning, thus ensuring the service life of engineering structures.

[0003] Construction joints are frequently encountered during construction. They are the joints formed between sections of concrete poured at different times, according to design requirements or construction needs. Because the later-poured concrete cannot mix with the already-set earlier-poured concrete, the concrete will separate into layers. The interface between these two layers is called a construction joint. Since construction joints are prone to water seepage, a waterproofing strip is installed at the joint to prevent this.

[0004] Currently, in formwork construction, waterstops are generally fixed by directly clamping them between the upper and lower formwork. This method has poor fixing effect, and the waterstop is difficult to be firmly positioned. It is prone to displacement during concrete pouring, which leads to deviation between the waterstop hole and the expansion joint. Summary of the Invention

[0027] A slide groove is provided on the connecting plate to limit the movement of the clamping plate, and the clamping plate is slidably connected to the slide groove.

[0028] As a further preferred embodiment of this technical solution: the clamping plates are provided in two sets, and are respectively provided at both ends of the connecting plate, and the inner side of the clamping plates is provided with anti-slip stripes.

[0035] Compared with the prior art, the beneficial effects of the present invention are:

[0036] 1. In this invention, the upper limit of the support rod and the double-sided clamping of the bottom of the limit plate form an omnidirectional constraint, which can effectively resist the impact and lateral pressure during concrete pouring. This fundamentally prevents the rubber waterstop from floating, shifting, twisting and sinking, ensuring that the hole in the waterstop is always accurately aligned with the position of the expansion joint, and significantly improving the reliability of the sealing and waterproofing of the construction joint.

[0037] 2. In this invention, the limiting mechanism adopts a triple locking design of gear tooth groove self-locking + T-groove anti-loosening + bolt positioning. Combined with the limiting plate that can steplessly adjust the angle and position, it can quickly adapt to rubber waterstops of different specifications and installation postures. The adjustment operation is simple, the positioning is firm and does not loosen, and it can be reused, which greatly reduces the difficulty of on-site installation and construction costs.

[0038] 3. The positioning component adopts a double-clamp anti-slip clamping design, which is firmly connected to the positioning steel bar without slipping or rotating. At the same time, the splicing component can flexibly extend and splice multiple sets of support rods to meet the needs of long-distance and multi-scenario construction. The overall structure is quick to install and highly versatile, effectively solving the problems of unreliable positioning and poor adaptability of traditional waterstop fixing methods.

[0052] Example

[0053] Please see Figures 1-6 As shown, the present invention provides a technical solution: a waterstop anti-deformation fixing structure, comprising: a support rod 2, arranged above the rubber waterstop body 1, for limiting the position of the rubber waterstop body 1 during concrete pouring; a limiting mechanism, including limiting plates 301 attached to both sides of the rubber waterstop body 1, for limiting the bottom of the rubber waterstop body 1 during pouring; a positioning component, including a connecting plate 401 arranged on one side of the support rod 2, for fixing the support rod 2 to the positioning reinforcement; and a splicing component for splicing multiple sets of support rods 2.

[0054] It should be noted that the support rod 2 is the main load-bearing component, which is arranged above the rubber waterstop body 1 to achieve the upper limit position; the limiting plate 301 is attached to both sides of the waterstop to achieve the bottom limit position; the support rod 2 is fixed to the positioning steel bar through the connecting plate 401; and multiple sets of support rods 2 are connected by splicing components to form an all-directional constraint on the waterstop in the upper, lower, left and right directions, which solves the problem of easy displacement and deformation during pouring. The whole can be fixed and spliced, and is suitable for on-site construction.

[0055] In this embodiment, specifically, the limiting mechanism further includes: an adjusting rod 302 for supporting the limiting plate 301, with the limiting plate 301 hinged to one end of the adjusting rod 302; a spur gear 303 fixedly arranged at the end of the adjusting rod 302 away from the limiting plate 301, for limiting the adjusted adjusting rod 302 after adjustment; an adjusting block 304 for supporting the adjusting rod 302; a toothed groove 305 formed in the adjusting block 304 for limiting the spur gear 303, with the spur gear 303 meshing with the toothed groove 305, and one end of the adjusting rod 302 slidingly and rotatably connected to the adjusting block 304; a return spring 306, one end fixedly arranged on one side of the spur gear 303, and the other end abutting against the adjusting block 304; and a limiting groove 307 formed on the support rod 2, with the adjusting block 304 slidably connected to the limiting groove 307.

[0056] The limiting plate 301 is hinged to the end of the adjusting rod 302 and can adaptively fit the contour of the waterstop. The outer end of the adjusting rod 302 is fixed to the spherical gear 303, which meshes in the tooth groove 305 in the adjusting block 304. Pulling the adjusting rod 302 outward to disengage the gear will rotate the angle adjustment. The return spring 306 will rebound to re-engage and lock the gear. The adjusting block 304 can slide and position itself in the T-shaped limiting groove 307 of the support rod 2, realizing stepless adjustment of the angle of the limiting plate 301, fitting waterstops of different specifications, with convenient adjustment, reliable positioning, and no loosening.

[0057] In this embodiment, the limiting mechanism further includes: a vertical plate 308, which is fixedly arranged on the upper end of the adjusting block 304; a limiting bolt 309, which is threaded through the vertical plate 308 and used to limit the moving adjusting block 304; and a limiting hole 310, which is opened on one side of the support rod 2, and one end of the limiting bolt 309 is engaged in the limiting hole 310.

[0058] It should also be understood that the upper end of the adjusting block 304 is provided with a vertical plate 308, and the limiting bolt 309 passes through the vertical plate 308 and is inserted into the limiting hole 310 on the side wall of the support rod 2, so as to completely fix the horizontal position of the adjusting block 304, prevent the adjusting block 304 from slipping due to the impact of pouring, ensure the position of the limiting plate 301 is stable for a long time, and improve the overall anti-disturbance ability.

[0059] In this embodiment, specifically: the adjustment block 304 is provided in several groups, and the limiting hole 310 is provided in several groups.

[0060] In addition, multiple sets of adjustment blocks 304 and multiple sets of limiting holes 310 are set up and arranged at multiple points along the length of the waterstop to achieve segmented and multi-point clamping, so that the long-distance waterstop is subjected to uniform force and no local warping or deviation occurs.

[0061] In this embodiment, specifically: the limiting groove 307 is T-shaped, and one end of the adjusting block 304 is T-shaped to fit the limiting groove 307.

[0062] It should be noted that the limiting groove 307 on the support rod 2 is T-shaped, and the end of the adjusting block 304 is a matching T-shaped structure. It slides and cannot be dislodged laterally. The adjusting block 304 only slides without dislodging or tipping over, making the movement smooth, with stronger load-bearing capacity, and safe and stable.

[0063] In this embodiment, the positioning component further includes: a clamping plate 402 for fixing the connecting plate 401 to the positioning reinforcing bar; a threaded rod 403 for threaded connection to the connecting plate 401, with one end rotatably connected to a T-shaped groove on one side of the clamping plate 402 for moving the clamping plate 402; and a sliding groove 404 for limiting the clamping plate 402, with the clamping plate 402 slidably connected to the sliding groove 404.

[0064] The threaded rod 403 is screwed into the connecting plate 401, and its end rotates in the T-shaped groove of the clamping plate 402, pushing the clamping plate 402 to move along the sliding groove 404, thereby clamping and releasing the positioning steel bar. The threaded drive clamping has controllable force and firm clamping. The overall structure is quickly fixed to the steel bar and is easy to disassemble and assemble.

[0065] In this embodiment, specifically: two sets of clamping plates 402 are provided, and are respectively provided at both ends of the connecting plate 401, and anti-slip stripes are provided on the inner side of the clamping plates 402.

[0066] It should also be understood that each end of the connecting plate 401 is equipped with a set of clamping plates 402, with anti-slip stripes on the inner side, bi-directional clamping positioning steel bars, double-point clamping + anti-slip, so that it does not slip or rotate, making the overall support more stable and not shaking with the impact of concrete.

[0067] In this embodiment, specifically: the splicing component includes: a splicing groove 501, which is formed and arranged on the connecting plate 401 for connecting multiple sets of support rods 2, and one end of the support rod 2 is slidably connected to the splicing groove 501; a splicing plate 502, which is fixedly arranged at both ends of the support rod 2 for supporting the support rod 2; and a fixing bolt 503, which is slidably connected through the splicing plate 502 and threadedly connected to the threaded hole at the upper end of the connecting plate 401.

[0068] In addition, the end of the support rod 2 is inserted into the splicing groove 501 of the connecting plate 401, and the splicing plate 502 is locked to the connecting plate 401 by the fixing bolt 503. The splicing is firm and the coaxiality is high. The multiple sections of the support rod 2 are connected into a whole, and the length can be freely extended.

[0069] In this embodiment, specifically: several sets of splicing grooves 501 are provided, and they are respectively opened on both sides of the connecting plate 401.

[0070] Among them, multiple splicing slots 501 are opened on both sides of the connecting plate 401, which can simultaneously connect multiple support rods 2.

[0071] In this embodiment, specifically: two sets of support rods 2 are provided, and they are respectively located on both sides of the rubber waterstop body 1.

[0072] Working principle or structural principle: When in use, first place two sets of support rods 2 on the upper sides of the rubber waterstop body 1 respectively. The positioning component completes the reliable connection between the overall structure and the positioning steel bars on the construction site. Then, by rotating the threaded rod 403, the clamping plate 402 moves towards each other along the sliding groove 404 on the connecting plate 401, so that the two sets of clamping plates 402 clamp the positioning steel bars. The anti-slip stripes on the inner side of the clamping plate 402 increase the clamping friction, so as to prevent the overall structure from shaking or shifting during the pouring process, thus providing a stable support foundation for the waterstop.

[0073] Subsequently, the bottom of the waterstop is precisely positioned and fixed using a limiting mechanism. The adjusting block 304 is pushed to slide along the T-shaped limiting groove 307 on the support rod 2, moving the limiting plate 301 to a position that matches both sides of the bottom of the waterstop. The adjusting rod 302 is pulled outwards to disengage the sprocket 303 from the toothed groove 305 inside the adjusting block 304. At this point, the adjusting rod 302 can be freely rotated to adjust the angle and height of the limiting plate 301, ensuring it fully conforms to the side of the waterstop. The adjusting rod 302 is then released. 2. The return spring 306 rebounds and pushes the spherical gear 303 to re-mesh with the tooth groove 305, completing the self-locking of the angle of the adjustment rod 302. Then, tighten the limiting bolt 309 on the upper vertical plate 308 of the adjustment block 304 so that it is inserted into the corresponding limiting hole 310 on the side wall of the support rod 2, and completely fix the position of the adjustment block 304. This ensures that the limiting plate 301 continuously and stably clamps the bottom of the waterstop, preventing the waterstop from shifting left and right, sinking or twisting under the action of concrete side pressure.

[0074] At the same time, the support rod 2 directly presses on the rubber waterstop body 1, forming a limiting constraint on the upper part of the waterstop, avoiding the waterstop from arching or shifting due to the impact of concrete pouring, and forming a limit protection in all directions (up, down, left, and right) with the bottom limiting plate 301, so that the waterstop always maintains the designed position and ensures that the central hole of the waterstop is precisely aligned with the deformation joint.

[0075] In addition, according to the construction length requirements of the waterstop, multiple sets of support rods 2 can be spliced ​​and extended using splicing components. The ends of the support rods 2 are inserted into the splicing grooves 501 on both sides of the connecting plate 401, and then the fixing bolts 503 are passed through the threaded holes at the top of the splicing plate 502 and the connecting plate 401 to complete the locking and fixing, so as to achieve a stable connection of multiple support rods 2, which can be adapted to construction scenarios of different lengths. The overall structure completely solves the problems of poor positioning and easy displacement and deformation of traditional fixing methods through all-round limiting, reliable fixing and flexible splicing, effectively ensuring the sealing and waterproofing effect of the construction joint and the construction quality of the project. Finally, it can be removed after the concrete is poured.
