Abstract
Description
Technical Field
[0001] This utility model relates to the field of expansion reinforcement strip technology, specifically a concrete expansion reinforcement strip. Background Technology
[0002] In construction engineering, the durability and safety of concrete structures are crucial; however, they often face the problem of cracking due to factors such as temperature changes and shrinkage. Traditional construction methods often use expansion joints to address concrete shrinkage, but this increases construction complexity and cost, and may affect the structural integrity and waterproofing performance. Furthermore, while existing concrete expansion reinforcement strips can compensate for concrete shrinkage to some extent, they have limitations in the distribution and effectiveness of the expansion agent. When the expansion agent is added manually, it is easy for it to not act evenly and continuously on different parts of the concrete, resulting in poor crack control and potentially affecting the overall support strength of the expansion reinforcement strip. Utility Model Content
[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a concrete expansion reinforcement strip to solve the problems of uneven expansion, low strength, easy cracking and damage, and complex structure of the concrete expansion reinforcement strip mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a concrete expansion reinforcing strip, comprising a first reinforcing bar for transverse force bearing, a second reinforcing bar for longitudinal force bearing, and concrete for pouring. The first and second reinforcing bars intersect to form a reinforcing mesh base. The concrete and the reinforcing mesh base are poured to form a concrete expansion reinforcing strip matrix. An infusion tube is provided on the reinforcing mesh base at positions corresponding to the first and second reinforcing bars. A plurality of reservoir tubes for temporarily storing expansion agent and capable of outputting expansion agent are provided between the infusion tubes and the reinforcing mesh base. The reservoir tubes are connected to the infusion tubes and are detachably connected to the reinforcing mesh base. The infusion tubes deliver liquid into the reservoir tubes.
[0005] As a further improvement of this utility model, at least one ring is slidably provided on the steel mesh base corresponding to each storage tube position. The ring is sleeved on the steel mesh base, and a limiting through hole is formed between the ring and the steel mesh base. After the storage tube is inserted into the limiting through hole, it can be positioned on the steel mesh base.
[0006] As a further improvement of this utility model, the storage tube is provided with a limiting wing at the position corresponding to the limiting through hole, and the limiting wing is inserted into the limiting through hole to form the positioning of the storage tube on the steel mesh base.
[0007] As a further improvement of this utility model, the limiting wing is provided with a soft pad for forming an interference fit with the limiting through hole, and the ring buckle can press the soft pad after being connected to the limiting wing.
[0008] As a further improvement of this utility model, the infusion tubing is provided to extend through the reservoir tube from the beginning to the end of the reservoir tube along the length direction of the reservoir tube. The infusion tubing is provided with a number of injection holes for injecting expansion agent into the reservoir tube at the corresponding positions of the reservoir tube. The connection between the infusion tubing and the reservoir tube is sealed. The reservoir tube is provided with an output hole for discharging the expansion agent.
[0009] As a further improvement of this utility model, a one-way valve is provided in the output port.
[0010] Compared with the prior art, this utility model provides a concrete expansion reinforcing strip with the following advantages: The reinforcing mesh base of this concrete expansion reinforcing strip is formed by a combination of several first reinforcing bars for transverse force and second reinforcing bars for longitudinal force, resulting in high base strength and better stability after pouring. This solution uses infusion hoses and storage pipes on the reinforcing mesh base for transporting and storing the expansion agent, and can output the expansion agent from the storage pipes. This allows the expansion agent to be evenly output at each location with a storage pipe after the concrete is poured, making the expansion reinforcing strip expand more evenly, improving the strength of the expanded reinforcing strip, and preventing cracking. The operation is simple, as the infusion hoses and storage pipes are installed simultaneously with the reinforcing mesh base, saving time and effort, and the structure is simple and easy to operate.

[0016] As shown in the figure, to achieve the above-mentioned objective, this utility model provides a concrete expansion reinforcing strip 3, including a first reinforcing bar 1 for transverse force bearing, a second reinforcing bar 2 for longitudinal force bearing, and concrete 3 for pouring. The first reinforcing bar 1 and the second reinforcing bar 2 intersect to form a reinforcing mesh base. The concrete 3 and the reinforcing mesh base are poured to form a concrete expansion reinforcing strip matrix. An infusion tube 4 is provided on the reinforcing mesh base at positions corresponding to the first reinforcing bar 1 and the second reinforcing bar 2. A plurality of storage tubes 5 for temporarily storing expansion agent and capable of outputting expansion agent are provided between the infusion tubes 4 and the reinforcing mesh base. The storage tubes 5 are connected to the infusion tubes. The storage tubes 5 are detachably connected to the reinforcing mesh base. The infusion tubes 4 deliver liquid into the storage tubes 5.
[0017] In this implementation, a first reinforcing bar 1 for lateral force bearing, a second reinforcing bar 2 for longitudinal force bearing, and concrete 3 for pouring are used. The first reinforcing bar 1 and the second reinforcing bar 2 intersect perpendicularly to each other, forming a stable reinforcing mesh base through binding or welding. The reinforcing mesh base serves as the skeleton of the expansion reinforcement strip of concrete 3, providing necessary mechanical support for concrete 3, ensuring the structural stability of concrete 3 under various loads, and also providing a foundation for the installation of other components. The concrete 3 and the reinforcing mesh base are poured to form the concrete expansion reinforcement strip matrix. In actual construction, those skilled in the art must strictly follow the concrete 3 mix proportion and pouring process to ensure that concrete 3 uniformly wraps the reinforcing mesh base, fully utilizing the synergistic performance of the reinforcing bars and concrete 3. On the reinforcing mesh base, corresponding to the positions of the first reinforcing bar 1 and the second reinforcing bar 2, infusion hoses 4 are installed. The infusion hoses 4 are arranged along the direction of the reinforcing bars and are fixedly connected to the reinforcing bars by binding straps or special clamps to prevent displacement or detachment during construction and ensure positional stability. This scheme preferably uses infusion hoses 4, as the rubber tubing is soft, not easily damaged by pressure, and has good corrosion resistance, making it suitable for transporting different liquids. Several storage tubes 5 are installed between the infusion hose 4 and the reinforcing mesh base. The storage tubes 5 are used to temporarily store the expanding agent and deliver it to the concrete 3 as needed. The storage tubes 5 are connected to the infusion hose 4, allowing the liquid in the infusion hose 4 to be smoothly delivered to the storage tubes 5. The storage tubes 5 and the reinforcing mesh base are detachably connected, which can be achieved through hooks, plugs, or other detachable fixing methods. This connection method allows for adjustment of the position and number of storage tubes 5 according to actual needs during construction, improving construction flexibility and convenience. Before pouring the concrete 3, the storage tubes 5 are installed on the reinforcing mesh base, and an appropriate amount of expanding agent is filled into the storage tubes 5. The filling amount is determined according to the design requirements of the expansion reinforcement strip of the concrete 3 and the actual construction conditions. The infusion hose 4 delivers liquid to the storage tubes 5, which can be achieved by connecting a pressure pump to the infusion hose 4. During the concrete 3 pouring process or at a specific time after pouring, the pressure pump is activated, allowing the liquid in the infusion hose 4 to flow to the storage tubes 5 under pressure. After the liquid enters the storage pipe 5, it mixes with the expanding agent, and then the mixed expanding agent solution is delivered to the concrete 3 through the open end of the storage pipe 5. By controlling the working time and pressure of the pressure pump, the output amount and output speed of the expanding agent can be precisely controlled, ensuring that the expanding agent is evenly distributed in the concrete 3, effectively compensating for the shrinkage of the concrete 3, and improving the crack resistance of the concrete 3. Those skilled in the art can set the length and width of the expansion reinforcement strip of the concrete 3 according to the actual situation, and rationally arrange the number and spacing of the first reinforcing bar 1, the second reinforcing bar 2, the liquid delivery hose 4, and the storage pipe 5 in combination with the structural stress characteristics of the concrete 3. The material, diameter, and other parameters of the liquid delivery hose 4 and the storage pipe 5 can also be optimized to meet different engineering needs.
[0018] At least one ring 6 is slidably provided on the steel mesh base corresponding to each storage tube 5 position. The ring 6 is sleeved on the steel mesh base, and a limiting through hole 7 is formed between the ring 6 and the steel mesh base. After the storage tube 5 is inserted into the limiting through hole 7, it can be positioned on the steel mesh base.
[0019] When implementing this solution, those skilled in the art need to fix each storage tube 5 to the reinforcing mesh base to prevent it from falling off. The preferred fixing method of this solution is to set a ring buckle 6 on the reinforcing mesh base. Those skilled in the art can set ring buckles 6 for both the first reinforcing bar 1 and the second reinforcing bar 2, and one ring buckle 6 corresponds to one storage tube 5. In other solutions, multiple ring buckles 6 can also be set for one storage tube 5 to increase the connection strength between the storage tube 5 and the reinforcing mesh base. The through hole formed between the ring buckle 6 and the reinforcing mesh base is used to partially insert the storage tube 5 into it, so that the reinforcing mesh base, the storage tube 5 and the ring buckle 6 form a snap-fit connection. The structure is simple and the snap-fit connection is convenient.
[0020] The storage tube 5 is provided with a limiting wing 8 at the position corresponding to the limiting through hole 7. The limiting wing 8 is inserted into the limiting through hole 7 to form the positioning of the storage tube 5 on the steel mesh base.
[0021] This solution uses a limiting wing 8 on the storage pipe 5. The limiting wing 8 in this solution is flat in shape, which is more suitable for smaller limiting through holes 7, saves space, avoids gaps in the expansion reinforcement strip of concrete 3, and makes insertion more convenient.
[0022] The limiting wing 8 is provided with a soft pad 9 for forming an interference fit with the limiting through hole 7. After the ring buckle 6 is connected to the limiting wing 8, it can press the soft pad 9 tightly.
[0023] In this solution, a soft pad 9 is placed on the limiting wing 8. This soft pad 9 can be attached to the limiting wing 8 by means of adhesive, which is convenient to operate. After the limiting wing 8 is inserted into the limiting through hole 7 and forms a snap-fit with the ring 6, the ring 6 will squeeze the soft pad 9 to deform it, thereby making the two form an interference fit, preventing the limiting wing 8 from falling out of the ring 6. The soft pad 9 can also reduce the impact of the vibration generated by the concrete 3 during pouring on the storage pipe 5.
[0024] The infusion tubing 4 extends through the reservoir tube 5 from its beginning to its end along the length of the reservoir tube 5. The infusion tubing 4 has several injection holes 10 evenly distributed at the position of the reservoir tube 5, which are for injecting expansion agent into the reservoir. The connection between the infusion tubing 4 and the reservoir tube 5 is sealed. The reservoir tube 5 is provided with an output hole 11 for discharging the expansion agent.
[0025] In implementation, the infusion hose 4 runs along the length of the storage tube 5 from its beginning to its end. Several injection holes 10 are evenly distributed at positions on the infusion hose 4 corresponding to the cavity of the storage tube 5. The connection between the infusion hose 4 and the storage tube 5 is sealed using sealant, sealing rings, or other methods to prevent leakage of the expanding agent. The storage tube 5 is equipped with an outlet hole 11 for discharging the expanding agent into the concrete 3. When a person skilled in the art starts the pressure pump, the expanding agent solution in the infusion hose 4 enters the cavity of the storage tube 5 through the injection holes 10. Because the injection holes 10 are evenly distributed, the expanding agent is uniformly distributed within the storage tube 5. Subsequently, the expanding agent is evenly released into the concrete 3 through the outlet hole 11 of the storage tube 5, according to design requirements, further optimizing the delivery effect of the expanding agent and improving the crack resistance of the concrete 3.
[0026] A one-way valve 12 is provided in the output port 11.
[0027] In this solution, a one-way valve 12 is installed in the output hole 11. The one-way valve 12 can block some external dust from entering the output hole 11 used for discharging the expansion agent, thus preventing the output hole 11 from becoming blocked. Preferably, the one-way valve 12 in this solution is integrally formed with the output hole 11 during the manufacturing process.
[0028] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
