Description

[0002] In modern engineering construction, in order to meet construction requirements and enhance the connection strength between the building infill wall and the frame structure, multiple rows of steel bars need to be connected between the building infill wall and the frame structure. One end of the steel bar is positioned in the fixed hole in the frame structure by planting steel bars, and the other end is exposed and positioned on the building infill wall.
[0003] At present, the connection and positioning of steel bars in fixed holes are achieved through the bonding of AB type glue. Not only is the operation troublesome, but the most important thing is that a large amount of powder will remain inside the fixed holes when drilling. The powder will seriously affect the bonding effect of the AB type glue. Therefore, after the drilling is completed, the powder in the hole needs to be cleaned, and generally a second emptying is required. If the emptying is not thorough, it will further affect the connection strength between the steel bars and the frame structure. The mixing ratio of AB type glue is also very important. Manual glue mixing is used on the construction site, and the mixing ratio cannot be accurately grasped, resulting in a low construction qualification rate, which brings serious safety hazards to the actual construction.

[0031] The present application will be further described below with reference to the drawings and specific embodiments, but is not limited by the present application.
[0032] The plastic connecting piece for filling wall anchorage of building frame structure provided in the present application, with reference to Figures 1-5 , comprises:
[0033] A connecting sleeve 1, one end of the connecting sleeve 1 is provided with a scraper 10 and a layer plate 11, the scraper 10 and the layer plate 11 are rotationally connected with the same push rod 8 and linkage rod 9 in the axial direction, the other end of the push rod 8 and the linkage rod 9 is respectively connected with a push plate 5 and a positioning plate 6, and the push plate 5 and the positioning plate 6 are provided with a spring 7; the scraper 10 and the layer plate 11 in the connecting sleeve 1 are provided with a storage cavity for storing dust in the hole, so that the dust on the inner wall of the hole is pressed into the storage cavity inside the connecting sleeve 1, and the dust is removed by sliding out of the positioning plate 6; and the inside of the connecting sleeve 1 after cleaning is fixedly connected with a plastic fixing tube 2 provided with a reinforcing bar.
[0034] Specifically, in the embodiment, the connecting sleeve 1 is designed as a hollow structure, the scraper 10 and the layer plate 11 are located at the opening end of the connecting sleeve 1 and can rotate around the axial direction of the connecting sleeve 1 under external driving, the push rod 8 is connected with the push plate 5, the positioning plate 6, the scraper 10 and the layer plate 11 in sequence, the linkage rod 9 is connected with the positioning plate 6, the scraper 10 and the layer plate 11 in sequence, and the push rod 8 and the linkage rod 9 conduct force and control the action of the scraper 10 / layer plate 11, in addition, the spring 7 between the push plate 5 and the positioning plate 6 can ensure that the force during pushing and pulling is balanced and the positioning is stable; the storage cavity is surrounded by the scraper 10 and the layer plate 11 and is used for collecting the dust accumulated on the inner wall of the hole. The insertion stage is to place the connecting sleeve 1 into the hole to ensure that the scraper 10 and the layer plate 11 are aligned with the hole wall, in the cleaning stage, the push plate 5 is manually or mechanically pushed, the spring 7 is compressed under stress, the push rod 8 and the linkage rod 9 are linked, the scraper 10 and the layer plate 11 are rotated and closely attached to the hole wall for cleaning. In the storage stage, the dust is pressed into the storage cavity by the scraper 10 and is stored by sliding with the positioning plate 6. In the emptying stage, the positioning plate 6 moves outward, the dust moves with the positioning plate 6 and completely separates from the hole. Therefore, in the structure of the present application, the scraper 10 and the layer plate 11 accurately fit the hole wall to ensure that there is no dust residue, the push-pull design is simple and intuitive, is convenient for on-site construction personnel to operate, and is made of high-toughness plastic, is durable and is not easy to damage the hole wall. The plastic connecting piece provided by the present application is not only suitable for cleaning the hole before filling wall bar planting, but also has the characteristics of high efficiency, convenience and environmental protection.
[0035] In the embodiment, referring to Figure 2 , one end of the plastic fixing tube 2 is provided with a limiting ring 3 with an outer diameter larger than that of the connecting sleeve 1, the limiting ring 3 effectively prevents the plastic fixing tube 2 from accidentally deepening into the hole to a position too deep, ensures the safety and accuracy of construction, ensures that the plastic fixing tube 2 can accurately reach the preset depth when planted into the hole, and improves the accuracy and efficiency of the bar planting project. Moreover, when the limiting ring 3 contacts the edge of the hole, an additional support point is formed, which increases the stability of the overall structure and prevents the plastic fixing tube 2 from deviating during subsequent construction. In addition, the limiting ring 3 indirectly avoids damage to the edge of the hole caused by forced insertion, thereby maintaining the integrity of the wall.
[0036] In the embodiment, referring to Figure 2, the plastic fixing tube 2 is internally provided with a bevel gear 4. The existence of the bevel gear 4 increases the friction between the plastic fixing tube 2 and the inner wall of the hole, significantly improves the pullout strength of the overall structure, and ensures that the reinforcing bar is more firmly fixed. The surface of the bevel gear 4 is a bevel surface that faces the limiting ring 3. The bevel surface is designed towards the limiting ring 3, which means that during the process of planting the reinforcing bar, once it is subjected to a reverse force, the bevel gear 4 will be more tightly engaged with the hole wall, preventing loosening or pulling out, and enhancing the reliability of the structure.
[0037] With reference to Figure 3 , the inner surface of the connecting sleeve 1 is provided with internal threads near the limiting ring 3, and the outer surface of the plastic fixing tube 2 is provided with external threads matching the internal threads. The matching of the internal threads and the external threads ensures the accurate alignment of the connecting sleeve 1 and the plastic fixing tube 2, improving the accuracy of the reinforcing bar operation. The engagement of the threads provides a firm physical connection, which can maintain the stability of the connection even in complex construction environments, avoiding loosening. Threaded connection allows quick assembly and disassembly, facilitating adjustment and maintenance during construction, and improving work efficiency. In addition, the threaded connection plays a sealing role to some extent, reducing the influence of dust or other impurities inside the hole, and maintaining the cleanliness of the reinforcing bar area.
[0038] In this embodiment, with reference to Figure 2 , one end of the connecting sleeve 1 is provided with a bevel surface. The bevel design greatly reduces the resistance when the connecting sleeve 1 is inserted into the hole, ensuring a smooth and unobstructed entry process. The bevel surface is designed with a ring-shaped tip at one end, which facilitates the insertion of the connecting sleeve 1 into the hole, improves construction accuracy, and ensures that the connecting part is correctly positioned. The bevel and tip structure reduces friction with the hole wall, prolongs the service life of the connecting sleeve 1, and also protects the hole wall from damage. In addition, the bevel naturally guides the internal substances (such as residual dust) in the hole to flow into the connecting sleeve 1, improving the cleaning efficiency.
[0039] In this embodiment, with reference to Figure 3 , the outer diameter of the scraper 10 is smaller than the inner diameter of the connecting sleeve 1, which is designed to ensure that it can rotate flexibly inside the connecting sleeve 1 to perform the cleaning task, while avoiding direct contact with the inner wall of the connecting sleeve 1 to reduce friction and wear. The diameter of the layer plate 11 is smaller than the diameter of the scraper 10, so that the layer plate 11 can be closer to the hole wall when the scraper 10 rotates, achieving a more thorough cleaning effect, while avoiding the increase of rotation resistance caused by excessive size. The size difference between the scraper 10 and the layer plate 11, as well as the reasonable gap between them and the inner diameter of the connecting sleeve 1, together ensure the balance between efficient cleaning and structural compactness, achieving deep cleaning while maintaining the structural integrity of the connecting sleeve 1.
[0040] With reference to Figures 4-5, the linkage rod 9 and the scraper 10 are connected in the middle to ensure the uniform distribution of force when the scraper 10 rotates, which helps to clean the hole wall more efficiently, while reducing the equipment damage that may be caused by uneven force. The push rod 8 and the layer plate 11 are connected at the bottom: the gravity assistance is effectively utilized, so that the layer plate 11 can fit more closely to the bottom of the hole under the push of the push rod 8, thereby enhancing the cleaning effect and ensuring the stable rotation of the layer plate 11. The position layout of the linkage rod 9 and the push rod 8 realizes the precise transmission of force, ensures the effective work of the scraper 10 and the layer plate 11 in the hole, and improves the overall cleaning efficiency. Through the above design, the present invention not only improves the cleaning efficiency, but also ensures the smooth and safe operation.
[0041] The construction method of the plastic connector for embedding reinforcement in the building frame structure provided by the present invention is as follows: Figures 1-5 , including the following steps:
[0042] Step 1: Drill holes in the wall to the desired depth;
[0043] Step 2: Insert the connecting sleeve 1 into the hole. The powder in the hole is squeezed into the interior of the connecting sleeve 1. By pushing the push plate 5 relative to the positioning plate 6, the push plate 5 squeezes the spring 7, driving the push rod 8 to move. The push rod 8 drives the scraper 10 and the layer plate 11 to rotate relative to the linkage rod 9, so that the scraper 10 and the layer plate 11 extend into the connecting sleeve 1. The scraper 10 and the layer plate 11 tilt and pass through the powder pile;
[0044] Step 3: Loosen the push plate 5, the scraper 10 and the layer plate 11 become vertical, pull the positioning plate 6 outward, and the scraper 10 and the layer plate 11 push the powder inside the connecting sleeve 1 out of the connecting sleeve 1;
[0045] Step 4: Heat the plastic fixing tube 2 with a flame until it softens, insert the steel bar into the plastic fixing tube 2, wait for the plastic fixing tube 2 to cool, and then insert the plastic fixing tube 2 into the connecting sleeve 1. Fix it through the threaded connection on the surface of the plastic fixing tube 2 and the connecting sleeve 1. The bevel teeth 4 limit the movement of the steel bar to ensure a firm connection between the steel bar and the wall.
[0046] This construction method ensures the cleanliness of the holes, enhances the connection strength between the steel bars and the filling wall, and provides protection for the safety and durability of the building structure.
[0047] The above are only preferred embodiments of the present invention and do not limit the implementation mode and protection scope of the present invention. For those skilled in the art, it should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
