Description

Technical Field

[0001] This utility model relates to the field of building industrialization technology, specifically to a grouting compensation system for prefabricated building walls. Background Technology

[0002] In the field of industrialized construction, with the rapid expansion of prefabricated building scale and the continuous improvement of structural safety requirements, higher standards have been set for the construction quality of prefabricated component connection nodes. As a core load-bearing node of prefabricated concrete walls, the grouting density of grouting sleeve connections directly determines the overall structural strength and seismic performance of the wall.

[0003] In traditional grouting processes, to address grout shrinkage or sealing defects after grouting with a grouting sleeve, a handheld grouting device is typically used for secondary grouting. Specifically, the grout outlet seal must first be removed, and then the handheld grouting device is directly inserted into the outlet to replenish the grout. However, during grouting, the device is susceptible to tipping due to grout flow or external interference, requiring frequent adjustments, leading to inconvenience and low efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a grouting compensation system for prefabricated building walls, which can conveniently and stably fill grout into prefabricated building walls and improve the grouting efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This utility model provides a grouting compensation system for prefabricated building walls, comprising:

[0007] The precast wall structure has a grouting sleeve inside, and grouting holes and grouting outlet holes that communicate with the grouting sleeve are opened on the precast wall structure. The grouting holes are located below the grouting outlet holes.

[0008] A flow guiding assembly includes a flow guiding channel with a fluid deflection portion, and the flow guiding assembly includes a first end and a second end opposite to each other, the first end being detachably connected to the slurry outlet, and the second end extending above the slurry outlet;

[0009] The compensation component is connected to the second end of the flow guiding component. The bottom of the compensation component has a discharge port, which is connected to the flow guiding channel. The compensation component is provided with an anchoring connection part, which is connected to the precast wall structure through a flexible connector. The compensation component is used to receive external slurry and pass it into the flow guiding channel.

[0010] Compared with existing technologies, the grouting compensation system for prefabricated building walls provided by this utility model, when grouting is required to fill the grouting sleeve in the prefabricated wall structure, first connects one end of the flow guiding component to the grout outlet. The compensation component is then connected to the prefabricated wall structure through the anchoring connection and flexible connector. External grout enters the flow guiding channel from the outlet of the compensation component at the first end of the flow guiding component. The fluid deflection part changes the grout flow direction, causing the grout to flow downwards along the flow guiding channel through the second end of the flow guiding component and into the grout outlet. The grout then flows from the outlet into the grouting sleeve, filling the cavity. This configuration ensures a stable connection between the compensation component and the prefabricated wall structure through the anchoring connection and flexible connector, maintaining the compensation component in a preset position throughout the grouting process. This reduces the impact of grout flow or external interference, maintaining the stability of the compensation component and the flow guiding component. Therefore, continuous supply of material to the compensation component ensures a continuous and stable grouting process, improving grouting efficiency.

[0011] Optionally, in the above-mentioned grouting compensation system for prefabricated building walls, the anchoring connection includes a pull ring set on the top of the compensation component, bolts are provided on the prefabricated wall structure, and a flexible connector connects the pull ring and the bolts.

[0012] Optionally, in the above-mentioned grouting compensation system for prefabricated building walls, the grouting compensation system for prefabricated building walls also includes a connecting structure. The connecting structure is a hollow tubular structure with both ends connected. One end of the connecting structure is connected to the first end of the flow guiding component, and the other end of the connecting structure is interference-fitted with the grout outlet hole.

[0013] Optionally, in the above-mentioned grouting compensation system for prefabricated building walls, the flow guiding component includes a flow guiding pipe, the pipe body of which forms a fluid deflection section through physical bending.

[0014] Optionally, in the above-mentioned grouting compensation system for prefabricated building walls, the bending angle of the fluid deflection section is 90°-135°.

[0015] Optionally, in the above-mentioned grouting compensation system for prefabricated building walls, the material of the flow guiding component is PVC.

[0016] Optionally, in the above-mentioned grouting compensation system for prefabricated building walls, the compensation component includes a conical funnel, the lower end of which contracts to form a discharge port, and the top of which opens to form a grout receiving port, with the cone angle of the conical funnel being 60°-75°.

[0017] Optionally, in the above-mentioned grouting compensation system for prefabricated building walls, the inner surface of the conical funnel has scale lines, which are used to monitor the grout volume in the conical funnel.

[0018] Optionally, in the above-mentioned grouting compensation system for prefabricated building walls, the conical funnel is a transparent conical funnel.

[0019] Optionally, in the above-mentioned grouting compensation system for prefabricated building walls, the compensation component includes a grout storage tank, the top of which is provided with an openable and closable sealing cover. Attached Figure Description

[0029] Firstly, please refer to Figure 1 The grouting compensation system for prefabricated building walls provided by this utility model includes a prefabricated wall structure 1, a flow guiding component 2, and a compensation component 3. The prefabricated wall structure 1 has an injection hole 120 and an outlet hole 130 communicating with a grouting sleeve 110, with the injection hole 120 located below the outlet hole 130. The flow guiding component 2 includes a flow guiding channel with a fluid deflection section, and includes a first end and a second end opposite to each other. The first end is detachably connected to the outlet hole 130, and the second end extends above the outlet hole 130. The compensation component 3 is connected to the second end of the flow guiding component 2, and has an outlet at its bottom. The compensation component 3 communicates with the flow guiding channel through the outlet. An anchoring connection part 310 is provided on the compensation component 3, and the anchoring connection part 310 is connected to the prefabricated wall structure 1 through a flexible connector 320. The compensation component 3 is used to receive external grout and guide it into the flow guiding channel.

[0030] In practice: When it is necessary to replenish the grouting sleeve 110 in the precast wall structure 1, first connect one end of the flow guiding component 2 to the grout outlet 130. The compensation component 3 is connected to the precast wall structure 1 through the anchoring connection 310 and the flexible connector 320. After the external grout enters the flow guiding channel from the first end of the flow guiding component 2 through the outlet of the compensation component 3, the fluid deflection part changes the flow direction of the grout, so that the grout flows from top to bottom along the flow guiding channel through the second end of the flow guiding component 2 and is injected into the grout outlet 130. The grout flows from the grout outlet 130 into the grouting sleeve 110 and fills the cavity therein. With this configuration, the compensation component 3 forms a stable connection with the precast wall structure 1 through the anchoring connection part 310 and the flexible connector 320, so that the compensation component 3 always maintains the preset orientation during the grouting process, reducing the impact of grout flow or external interference, and maintaining the stability of the compensation component 3 and the flow guiding component 2. Therefore, as long as the material is continuously supplied to the compensation component 3, the grouting process can be guaranteed to proceed continuously and stably, thus improving the grouting efficiency.

[0031] As one possible implementation, the anchoring connection 310 includes a pull ring disposed on the top of the compensation component 3, bolts disposed on the precast wall structure 1, and a flexible connector 320 connecting the pull ring and the bolts. It should be noted that the anchoring connection 310 may consist of several pull rings symmetrically arranged on the top of the compensation component 3 or a single pull ring. Bolts are pre-embedded in the precast wall structure 1, and the compensation component 3 is connected to the pre-embedded bolts via the flexible connector 320. The flexible connector 320 may be a nylon rope or rubber rope, etc., with its two ends connected to the pre-embedded bolts and pull rings on the precast wall structure 1, respectively, thereby stabilizing the compensation component 3. In some embodiments, the anchoring connection 310 may consist of multiple downward-facing hook structures symmetrically arranged on the side of the compensation component 3, and the flexible connector 320 may be a rubber band or rubber rope. Thus, the elasticity of the flexible connector 320 is used to stably connect the compensation component 3 to the precast wall structure 1, achieving stability of the compensation component 3.

[0032] As one possible implementation, the grouting compensation system for prefabricated building walls also includes a connecting structure 4, which is a hollow tubular structure with both ends open. One end of the connecting structure 4 is connected to the first end of the flow guiding component 2, and the other end of the connecting structure 4 is interference-fitted with the grout outlet 130.

[0033] The connecting structure 4 connects the flow channel and the slurry outlet 130 through a hollow tube. Its connection end with the flow guide component 2 is fixed, and its mating end with the slurry outlet 130 forms an interference fit through the difference in pipe diameter. During slurry replenishment, the slurry enters the hollow channel of the connecting structure 4 from the flow guide component 2, forming a directional flow path constrained by the interference fit surface, preventing lateral leakage. The tubular through-type design of the connecting structure 4, without increasing the resistance to slurry flow, while the radial pressure generated by the interference fit further ensures the connection stability between the flow guide component 2 and the slurry outlet 130. The connecting structure 4 achieves an integrated connection between the flow guide component 2 and the slurry outlet 130, replacing the traditional separate sealing method. The interference fit improves connection stability and facilitates installation, avoiding repeated adjustments and repositioning.

[0034] In some embodiments, the connecting structure 4 is an elastic tube made of rubber or silicone. The elastic tube is fixed to the flow guiding component 2 by a press-fit sleeve. During installation, the elastic tube is sleeved onto the first end of the flow guiding component 2, and a sealing contact surface is formed by the elastic deformation of the elastic tube. The other end of the elastic tube is inserted into the grout outlet 130, and an adaptive interference fit with the grout outlet 130 is achieved by the elastic deformation of the rubber tube. During grouting, the grout enters the connecting structure 4 through the flow guiding component 2 and then enters the grout outlet 130. The flexibility of the connecting structure 4 can absorb fluctuations in grouting pressure, prevent the joint from falling off, and improve the stability of the grouting operation.

[0035] As one possible implementation, the flow guiding component 2 includes a flow guiding pipe, the body of which is physically bent to form a fluid deflection section. In practice, when grouting is required, grout is added to the compensation component 3. External grout enters the flow guiding pipe from the discharge port of the compensation component 3. Within the flow guiding pipe, it passes through the fluid deflection section, which changes the original flow direction of the grout, transforming its vertical or downward direction into the direction of entering the grout outlet 130. This creates a directional flow path, allowing the grout to flow downwards along the flow guiding pipe into the grout outlet 130, and then into the grouting sleeve 110 to fill the cavity. This precise directional flow guidance, achieved by changing the grout flow direction through the fluid deflection section, combined with the continuous supply from the compensation component 3, ensures efficient grouting. Furthermore, this structure of the flow guiding pipe is simple, easy to manufacture and install, and has a low cost.

[0036] In some embodiments, the flow guiding component 2 can be a pipe with a valve installed in the flow guiding channel. The flow rate and direction of the slurry can be controlled by opening and closing the valve, allowing for flexible adjustment based on actual conditions during slurry replenishment and better adapting to different slurry replenishment needs. Alternatively, the flow guiding component 2 can be a spiral pipe, increasing the stroke of the slurry during the flow guiding process, making the slurry flow more stable, and also utilizing gravity and centrifugal force to assist the slurry flow to the outlet hole 130 to a certain extent, improving the slurry replenishment effect. Or, the flow guiding component 2 can be a multi-branched flow guiding pipe, with a main pipe connected to the outlet hole 130, and multiple branch pipes extending from the main pipe and connected to the compensation component 3. During slurry replenishment, the slurry can flow into the main pipe simultaneously from multiple branches and then be injected into the outlet hole 130. Compared with a single-pipe flow guide, a multi-branch flow guide can significantly improve the grouting efficiency, especially when facing a large-volume grouting sleeve 110 that requires rapid grouting. It can simultaneously obtain grout from multiple compensation components 3 to quickly fill the cavity inside the grouting sleeve 110, and can make the grout more evenly distributed inside the grouting sleeve 110.

[0037] In some embodiments, the flow guiding component 2 can be a flow guiding channel. The outlet of the flow guiding channel is aligned with the slurry outlet 130, and then slurry is injected into the flow guiding channel. The slurry can then enter the slurry outlet 130 along the passage of the flow guiding channel to complete the slurry replenishment operation.

[0038] As one possible implementation, the bending angle of the fluid deflector is 90°-135°. Located in the middle of the flow guiding assembly 2, this fluid deflector, through a geometric deflection structure at a specific angle, such as 90°, 100°, 110°, 120°, 130°, 135°, or any angle within this range, transforms the slurry from a vertical or inclined downward path to a horizontal flow direction, allowing it to be injected into the horizontal slurry outlet 130 on the surface of the precast wall structure 1. When the slurry falls from the compensation assembly 3 to the bending section, its gravitational potential energy drives the slurry to impact the inner wall of the bending section. The bending angle, through geometric constraints, transforms the slurry flow into a horizontal flow. A 90° bend allows for a sharp change of direction, suitable for rapid filling needs, while bends greater than 90°, such as 100° to 135°, can reduce flow resistance through gradual deflection, adapting to the smooth delivery of high-viscosity slurries. The design of the bent fluid deflector blocks the reverse flow of the slurry, avoids backflow that may occur when slurry replenishment is interrupted, and ensures the stability of the structure.

[0039] As one possible implementation, the flow guiding component 2 is made of PVC. PVC (polyvinyl chloride) flow guiding component 2 has a smooth inner surface, which reduces the flow resistance of the slurry and improves the uniformity of slurry flow, reducing the possibility of clogging. Simultaneously, PVC flow guiding component 2 has good corrosion resistance, can be exposed to complex construction environments for extended periods without chemical reaction, and has low density and is easy to install, while also offering the advantage of low cost. In some embodiments, the flow guiding component 2 can be made of fiberglass or polyethylene. Fiberglass has high strength and is suitable for construction scenarios susceptible to external impacts, while polyethylene has good flexibility and can be made into complex coiled flow guiding tubes, suitable for the needs of complex spatial arrangements.

[0040] As one possible implementation, the compensation component 3 includes a conical funnel, the lower end of which contracts to form a discharge port, and the top of which opens to form a slurry receiving port. The cone angle of the conical funnel is 60°-75°.

[0041] In practice, after the slurry is injected from the slurry receiving port at the top of the conical funnel, it slides naturally down the conical sidewall. The flow characteristics are controlled by the slope angle of the cone: larger cone angles, such as 70° or 75°, provide a steep downward path, using gravity to increase the flow velocity of the slurry and achieve rapid slurry replenishment; while smaller cone angles, such as 60° or 65°, form a gentle contraction channel, extending the residence time of the slurry to ensure uniform delivery. At the same time, the smooth surface of the inner wall of the conical funnel guides the slurry to form a laminar flow, effectively avoiding the problem of slurry residue adhering to the wall in traditional straight-walled containers.

[0042] As one possible implementation, the inner surface of the conical funnel has graduated lines used to monitor the slurry volume within the funnel. During slurry replenishment, as external slurry enters the funnel through the slurry receiving port formed by the top opening, the liquid level gradually rises with continuous slurry injection. The graduated lines conveniently display the change in slurry volume within the funnel. By observing the graduated lines, the real-time slurry level in the funnel can be monitored. When the slurry volume is found to be close to or below the required replenishment amount, slurry can be promptly added to the funnel to ensure continuous and stable slurry replenishment. This graduated conical funnel design allows for precise real-time control of the remaining slurry volume, enabling advance planning of slurry replenishment operations and preventing interruptions due to insufficient slurry, thus improving the continuity and stability of the replenishment process. Furthermore, monitoring the slurry volume through the graduated lines effectively controls the replenishment progress, preventing over-injection and improving the quality and efficiency of the replenishment work. In some embodiments, a removable scale plate can be installed on the inner surface of the conical funnel. The scale plate has scale lines, and the scale lines on different scale plates are different. It can be customized or replaced according to the actual grouting needs to adapt to different grouting work.

[0043] Furthermore, the conical funnel is a transparent conical funnel. Due to its transparency, the real-time status of the grout within the funnel can be clearly and intuitively observed during the grouting process, including the grout level, flow, and the presence of impurities. This allows for timely decision-making based on the observed grout conditions, such as promptly replenishing grout to maintain continuity and avoid interruptions due to insufficient grout; or taking immediate action to clean impurities if they are found, preventing them from entering the guide channel and grouting sleeve 110 and affecting the grouting quality. Simultaneously, the transparent conical funnel design complements the inner surface graduations, enabling more convenient and accurate reading of the graduations, further enhancing the control over grout volume. Compared to opaque conical funnels, the transparent conical funnel significantly improves the visibility of the grouting process, effectively increasing the efficiency and quality of grouting operations and reducing potential construction risks.

[0044] As one possible implementation, the compensation component 3 includes a slurry storage tank with an openable and closable sealing cap on top.

[0045] Specifically, a slurry storage tank with an openable and closable sealing cap is used as compensation component 3. Before slurry replenishment, the sealing cap is closed, effectively isolating external dust and impurities to prevent them from mixing into the slurry inside the tank, ensuring the purity of the slurry and guaranteeing high-quality slurry replenishment. When slurry needs to be added to the tank, the sealing cap is opened for quick replenishment. During slurry replenishment, closing the sealing cap prevents waste due to accidental spillage or splashing, while maintaining stable pressure inside the tank, allowing the slurry to enter the guide channel through the outlet at a relatively stable flow rate, ensuring the continuity and stability of the slurry replenishment process. Compared to open slurry storage devices, this slurry storage tank design with an openable and closable sealing cap not only improves the safety and hygiene of slurry storage but also reduces the risk of slurry replenishment being hindered due to slurry loss or contamination, thereby improving the overall efficiency and reliability of the slurry replenishment operation.

[0046] Furthermore, the side wall of the slurry storage tank is equipped with a transparent observation window or a level sensor. When the slurry storage tank is equipped with a transparent observation window, the liquid level and state of the slurry in the tank can be viewed directly and intuitively in real time during the slurry replenishment process. When the liquid level drops to a certain level and slurry needs to be replenished in time, it can be easily detected, allowing for timely replenishment and preventing interruptions in slurry replenishment due to insufficient slurry, thus ensuring the continuity of slurry replenishment work. At the same time, the observation window can also be used to observe whether there are any abnormalities such as sedimentation or stratification in the slurry, so that measures such as stirring can be taken in time to ensure slurry quality and improve the slurry replenishment effect. When a level sensor is installed, it can accurately monitor changes in the liquid level of the slurry in the storage tank and feed back the liquid level information in the form of a signal. Based on the information transmitted by the level sensor, slurry replenishment work can be planned in advance, achieving more efficient slurry replenishment operation management. Compared to the traditional method of manually opening the slurry storage tank to check the liquid level, the liquid level sensor not only reduces the number of operation steps and the risk of external impurities entering the slurry storage tank and contaminating the slurry, but also improves the automation and intelligence of the slurry replenishment process, effectively improving the efficiency and quality of slurry replenishment operations and reducing slurry replenishment problems caused by human negligence or improper operation.

[0048] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
