Description

Technical Field

[0001] This invention relates to the field of concrete pouring technology, and in particular to a device for preventing cracking and seepage at joints in poured concrete structures and its construction method. Background Technology

[0002] Concrete pouring refers to the construction process of pouring concrete into a mold until it is plasticized. It is mainly used in civil engineering projects. This process uses slag silicate cement, along with fine sand, gravel, and pumping agents. Before construction, it is necessary to complete preparatory work such as training operators. The pouring process includes cleaning the formwork, layered vibration, and continuous operation in sections.

[0003] Concrete pouring is a crucial process in construction engineering, and the crack prevention and seepage prevention treatment at the joints of concrete structures directly affects the overall quality and service life of the building. During the concrete pouring process and the curing stage after pouring, existing technologies have the following problems: temperature monitoring and curing control are independent, resulting in a delayed response. Current concrete curing mainly relies on manual experience for watering, or uses separate temperature and humidity monitoring equipment and curing spraying equipment. There is a lack of effective linkage control mechanism between the two systems. When the temperature difference between the inside and outside of the concrete is too large, it cannot automatically spray according to the temperature difference, leading to a delayed temperature control response and a tendency for temperature overshoot, resulting in unsatisfactory curing effects. The interface treatment process is fragmented, and the equipment has limited functionality. The interface treatment of new and old concrete joints involves multiple steps, such as roughening, cutting, washing, and applying an interface agent. In existing technologies, each step often requires different specialized equipment. For example, roughening requires an air compressor and pneumatic hammer, cutting requires an electric saw, washing requires a high-pressure water gun, and applying an interface agent requires a roller or spray gun. Each piece of equipment has limited functionality, and frequent site changes and repositioning are necessary during construction, resulting in long preparation times and high labor costs. Moreover, key parameters such as roughening depth and cutting position mainly rely on manual experience for control, making it difficult to guarantee accuracy and easily leading to problems such as under-roughening or over-roughening, which affects the bonding quality of new and old concrete. The mold clamping and positioning accuracy is low and the stability is poor. During the concrete pouring process, it is necessary to clamp and position the pouring mold to prevent it from shifting under the lateral pressure of the concrete. In the existing technology, mold clamping mainly relies on manual adjustment of the clamp position and fixation by bolts or clips. This method has low clamping accuracy, difficulty in height adjustment, and poor clamping stability. Under the vibration of concrete pouring, it is easy to loosen and shift, resulting in quality problems such as misalignment and grout leakage at the joint. At the same time, the interface treatment structure and the mold clamping structure are independent of each other. When switching between the interface treatment and pouring working states, manual disassembly and reinstallation are required, which increases the construction process and labor costs. Therefore, this application provides a crack prevention and seepage prevention device for the joints of poured concrete structures and its construction method to meet the requirements. Summary of the Invention

[0004] The technical problem to be solved by this invention is to provide a device for preventing cracking and seepage in the joints of cast concrete structures and its construction method to solve the problems of lack of linkage between temperature and humidity monitoring and curing control, and delayed temperature control response in existing concrete casting technology; the scattered interface treatment processes, single equipment functions, long construction preparation time, and high labor costs in existing technologies; and the problems of low mold clamping and positioning accuracy, poor stability, and easy misalignment of joints caused by concrete casting vibration in existing technologies.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A crack-prevention and seepage prevention device for joints of cast concrete structures and its construction method, comprising a base, a temperature and humidity control structure fixedly installed on the top of the base, a mold clamping structure fixedly installed in the middle of the top of the base, an interface treatment structure provided on the top of the base, and a flip-up storage structure movably sleeved on one side of the interface treatment structure, the flip-up storage structure being fixedly installed on one side of the top of the base. The temperature and humidity control structure includes a hollow shell, a liquid storage tank, a sprayer, a temperature controller, and a base plate. The hollow shell is fixedly installed on the top of the base. Sprayers are fixedly installed on both inner layers of the hollow shell. One side of each sprayer is connected to the liquid storage tank, which is fixedly installed on both sides of the outer surface of the hollow shell. Temperature controllers are fixedly installed on both inner layers of the hollow shell. The base plate is fixedly installed on the top of the base. A proportional linkage control loop is set between the sprayer and the temperature controller to automatically adjust the spray volume according to the difference when the temperature difference exceeds a preset threshold, avoiding the temperature overshoot problem caused by fixed spray volume and response lag. A liquid level feedback unit is set between the liquid storage tank and the sprayer to monitor the liquid level in the storage tank and alarm when the liquid level is below the warning line, ensuring the continuity of the maintenance process.

[0006] The mold clamping structure includes a pad, a receiving plate, a connecting frame, a straight groove, and a damping block. The pad is fixedly installed on the top surface of the base plate. The receiving plate is fixedly installed on the top of the pad. The connecting frame is fixedly installed on the top of the receiving plate. Straight grooves are opened on both sides of the top of the connecting frame. Damping blocks are movably engaged on both sides of the inner cavity of the straight groove. The damping blocks achieve horizontal position adjustment through a damping self-locking mechanism to prevent position displacement under external force. The mold clamping structure also includes a connecting seat, a telescopic controller, a telescopic rod, a connecting rod, a telescopic sleeve plate, and a telescopic shell. The connecting seat is fixedly installed on the top of the damping block. The telescopic controller is fixedly installed on the top of the connecting seat. The telescopic rod is fixedly installed on the top of the telescopic controller. The connecting rod is fixedly installed on the top of the telescopic rod. A telescopic sleeve plate is fixedly installed on one side of the connecting rod. A telescopic shell is movably fitted onto one end of the outer surface of the telescopic sleeve plate. The telescopic shell is fixedly installed on one side of another connecting rod. The cooperation of the telescopic controller and the telescopic rod enables vertical height adjustment. The horizontal and vertical adjustments are coupled and locked through a damping self-locking mechanism, improving clamping and positioning accuracy and effectively preventing misalignment of joints caused by mold displacement.

[0007] The interface processing structure includes a top plate, a locking block, a receiving block, a spring, a locking groove, a second connecting sleeve block, and a locking post. The springs are evenly and fixedly installed at the four top corners of the base. A receiving block is fixedly installed on the top of each spring. The top plate is fixedly installed on the top of each receiving block. Locking blocks are fixedly installed on the bottom two diagonally of the top plate. The locking blocks are movably engaged inside the locking groove. The locking groove is fixedly installed on the top of two other springs. A second connecting sleeve block is fixedly installed on both layers of the top plate. A locking post is fixedly fitted into the inner cavity of the second connecting sleeve block. The flipping motion of the top plate and the elastic support of the spring form a rigid-flexible coupling self-locking mechanism, realizing rapid locking and positioning after the top plate flips, without manual intervention.

[0008] The interface treatment structure also includes a water storage tank, a water inlet, a start button, a connecting pipe, a water tank, and high-pressure water nozzles. The water storage tank is fixedly installed on the top of the top plate. A water inlet is fixedly installed in the middle of the top of the water storage tank. A start button is fixedly installed on one side of the top of the water storage tank. The water tank is fixedly installed on one side of the top of the top plate. Both outer surfaces of the water storage tank are connected to connecting pipes. The bottom of the connecting pipes is connected to the water tank. The water tank is fixedly installed on both sides of the bottom of the top plate. The bottom of the water tank is connected to multiple high-pressure water nozzles. Through the cooperation of the connecting pipes and the water tank, high-pressure washing and cleaning of the roughened concrete surface is achieved, effectively removing debris and loose particles.

[0009] The interface processing structure also includes a connecting shell, a rotating column, a connecting sleeve, a connecting shaft, a rocker arm, and an arc-shaped groove. The connecting shell is fixedly installed at the bottom of the top plate. A rotating column is installed through the middle of the outer surface of the connecting shell. A connecting sleeve is fixedly sleeved on the outer surface of the rotating column. A connecting shaft is fixedly sleeved on one side of the connecting sleeve. A rocker arm is fixedly installed at one end of the connecting shaft. The other end of the connecting shaft is movably engaged inside the arc-shaped groove. The arc-shaped groove is fixedly installed on one side of the connecting shell. The rocker arm drives the connecting shaft to slide in the arc-shaped groove, causing the cutting component to rotate 180°, realizing one-click switching between the roughening mode and the cutting mode. The switching process does not require changing tools.

[0010] The interface treatment structure further includes a first connecting sleeve, an electric drill, an interface agent storage tank, a pad, and a liquid outlet. The first connecting sleeve is fixedly fitted onto both sides of the outer surface of the rotating column. An electric drill is fixedly installed on both sides of the top of the first connecting sleeve. An interface agent storage tank is fixedly installed on both layers of the first connecting sleeve. A pad is fixedly installed on the top of the interface agent storage tank, and a liquid outlet is fixedly installed in the center of the top of the pad. The electric drill, through the lifting and lowering movement of the rotating column and in cooperation with the depth limiting structure, enables precise control of the roughening depth. A metering pump control unit is provided between the interface agent storage tank and the liquid outlet to ensure uniform and consistent interface agent coating thickness.

[0011] The interface treatment structure also includes a stand, a connecting column, and a cutting strip. The stand is fixedly installed on both sides of the bottom of the first connecting sleeve block. The connecting column is fixedly installed on the inner side of the stand. The cutting strip is movably sleeved on the outer surface of the connecting column. The cutting strip and the chisel drill form a complementary interface treatment function. When the cutting strip is flipped to the working position, it can form a water-stop steel plate implantation groove at the joint, which facilitates the subsequent implantation of the water-stop steel plate and filling it with epoxy resin.

[0012] The flip-up storage structure includes a support telescopic rod, rubber clamping blocks, a fixed column, and movable sleeve blocks. The support telescopic rod is fixedly installed on both sides of the top of the base. Multiple rubber clamping blocks are fixedly installed on the outer surface of the support telescopic rod. A fixed column is fixedly sleeved in the top inner cavity of the support telescopic rod. Movable sleeve blocks are movably sleeved on both layers of the outer surface of the fixed column. The movable sleeve blocks are fixedly installed on one side of the top plate. Radial self-locking is achieved through the interference fit between the clamping column and the rubber clamping blocks, ensuring that the interface treatment structure will not shift due to the vibration of concrete pouring during the pouring process.

[0013] Compared with the prior art, the present invention has at least the following beneficial effects: 1. In the above solution, a proportional linkage control loop between the sprayer and the temperature controller is set in the temperature and humidity control structure. The temperature controller monitors the concrete surface temperature in real time and calculates the difference between the temperature and the ambient temperature. When the difference exceeds a preset threshold, the sprayer automatically adjusts the spray volume according to the difference, thereby achieving adaptive compensation control of the concrete temperature difference. This avoids the temperature overshoot problem caused by fixed spray volume and response lag in the prior art. At the same time, a liquid level feedback unit is set between the sprayer and the liquid storage tank. When the liquid level in the liquid storage tank is lower than the warning line, an alarm is automatically triggered to ensure the continuity of the curing process. This invention controls the internal and external temperature difference of concrete through the dual protection of adaptive temperature difference compensation and liquid level monitoring, effectively preventing the generation of temperature cracks.

[0014] 2. In the above solution, the interface treatment structure integrates four processes—sharpening, cutting, rinsing, and interface agent application—into a single workstation. A rigid-flexible coupling self-locking mechanism is formed by the flipping motion of the top plate and the elastic support of the spring. The locking block automatically engages with the receiving block under the pre-tension of the spring, achieving rapid locking and positioning. Furthermore, the sharpening assembly, through the lifting motion of the pressing top plate and the depth limiting structure of the electric drill, precisely controls the sharpening depth. The cutting mechanism drives the connecting shaft to slide within the arc-shaped groove via a rocker arm, causing the first connecting sleeve block to rotate 180°, enabling one-click switching between sharpening and cutting modes. The switching process requires no tool replacement. A metering pump control unit is installed between the interface agent storage tank and the outlet to ensure uniform interface agent application thickness. Through the synergistic effect of these technologies, the time required for a single joint interface treatment is reduced, significantly saving labor costs.

[0015] 3. In the above scheme, the coordinated function of the mold clamping structure and the flipping and storage structure achieves full-process positioning control of concrete pouring operations. The mold clamping structure adjusts its horizontal position by sliding the damping block along the straight groove, and adjusts its vertical height by extending and retracting the telescopic controller and telescopic rod. The horizontal and vertical adjustments are coupled and locked by the damping self-locking mechanism, improving clamping and positioning accuracy. The flipping and storage structure achieves radial self-locking when pouring is required by the rotation of the movable sleeve block around the fixed column and the interference fit between the top plate and the rubber clamping block through the locking column. This facilitates storage while ensuring that the interface treatment structure does not shift due to concrete pouring vibration. The telescopic fit between the telescopic sleeve plate and the telescopic sleeve shell can be adaptively adjusted according to the height of the pouring mold, eliminating the need for frequent manual adjustment of the clamp height. The synergistic effect of the above structures greatly shortens the pouring preparation time and improves the pouring accuracy, effectively preventing joint misalignment caused by mold displacement.

Radial self-locking is achieved by the interference fit between the locking post 427 and the rubber clamping block 52.

[0028] The technical solution provided by this invention firstly involves mold clamping and positioning. Based on the size of the concrete mold to be poured, the damping block 35 of the mold clamping structure 3 is pushed and pulled to drive the telescopic controller 37 and the telescopic sleeve 311 to adjust their horizontal position along the straight groove 34 of the connecting frame 33. The vertical height is adjusted by the extension and retraction of the telescopic controller 37 and the telescopic rod 38, so that the connecting rod 39 clamps and positions the pouring mold. Then, the interface treatment structure is flipped and unfolded. The top plate 421 of the interface treatment structure 4 is flipped over to the concrete joint. Under the elastic support of the spring 424, the top plate 421 is quickly locked into the receiving block 423 by the locking block 422, and the locking time is less than 2 seconds without manual intervention. Then, the surface is roughened. The top plate 421 is pressed to make the electric drill 414 contact the surface of the concrete part. The electric drill 414 is started to roughen the old concrete on the top of the concrete part, removing the surface laitance and exposing the coarse aggregate to form a rough and concave surface. The roughening depth is controlled within the required range. The roughening depth is controlled by the lifting and lowering movement of the top plate 421. After roughening, the surface is rinsed and cleaned. The roughened concrete part surface is rinsed with high pressure through the high-pressure water nozzle 47. The working pressure is 10MPa and the rinsing time is not less than 30 seconds to remove debris and loose particles. Then, the groove is cut. The rocker arm 411 drives the connecting shaft 410 to slide in the arc groove 412, causing the first connecting sleeve block 413 to rotate 180°, so that the cutting... The cutting strip 420 is flipped over to the top of the concrete component. The top plate 421 is pressed to cut the concrete with the cutting strip 420, forming a groove for the water-stop steel plate at the joint. After cutting, the water-stop steel plate is inserted, and epoxy resin is filled into the cutting groove. The water-stop steel plate is then inserted, and a water-swellable water-stop strip is arranged on each side of the steel plate. After the steel plate is inserted, an interface agent is applied. A carbon fiber mesh is placed on the top of the concrete component. Cement-based inorganic interface agent is evenly applied to the top of the concrete component through the outlet 417. Finally, the component is flipped and stored. When concrete is to be poured, the top plate 421 is lifted and rotated around the fixed column 53 via the movable sleeve block 54. This causes the interface treatment structure to be inserted into the rubber clamping block 52 through the clamping column 427, achieving flipping and storage. Then, high-grade slightly expanding concrete is poured to the joint. After the concrete is poured, the surface temperature of the concrete component is monitored in real time by the temperature controller 24, and the sprayer 23 automatically adjusts the spray volume according to the temperature difference for spraying and curing.
