Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a plastic connector for embedding reinforcement in a filling wall of a building frame structure and a construction method thereof. Background Art

[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, it is necessary to connect multiple rows of steel bars 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 embedding, 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 is achieved by bonding with AB type glue, which is not only troublesome to operate, but most importantly, 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 mix ratio of AB type glue is also very important. Manual glue mixing is used on the construction site, and the mix ratio cannot be accurately grasped, resulting in a low construction qualification rate, which brings serious safety hazards to the actual construction.

[0013] Optionally, the rotational connection positions of the linkage rod and the push rod with the scraper plate and the layer plate are respectively in the middle and the lower part.

[0014] A construction method for a plastic connector for embedding reinforcement in a building frame structure filling wall, comprising the following steps:

[0015] Step 1: Drill holes in the wall to a predetermined depth;

[0016] Step 2: insert the connecting sleeve into the hole, the powder in the hole is squeezed into the connecting sleeve, and the push plate is pushed to move relative to the positioning plate, the push plate squeezes the spring, drives the push rod to move, and the push rod drives the scraper and the layer plate to rotate relative to the linkage rod, so that the scraper and the layer plate extend into the connecting sleeve, and the scraper and the layer plate are tilted to pass through the powder pile;

[0020] 1. The device of the present invention solves the problem that the traditional blower and the electric heater need to be connected to an external power supply, the operation is cumbersome, and the dust flying after cleaning affects people's health, reduces the labor risk of operators, reduces the labor intensity of operators and reduces costs; it also solves the problem that the effect of the original process of anchor glue is affected by incomplete cleaning, and improves work efficiency;

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0031] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0032] The plastic connector for embedding reinforcement in the building frame structure infill wall provided by the present invention is referred to Figure 1-Figure 5 ,include:

[0033] A connecting sleeve 1, one end of which is provided with a scraper 10 and a layer plate 11, the scraper 10 and the layer plate 11 are axially rotatably connected with the same push rod 8 and the linkage rod 9, the other ends of the push rod 8 and the linkage rod 9 are respectively connected with a push plate 5 and a positioning plate 6, a spring 7 is arranged between the push plate 5 and the positioning plate 6; a storage cavity for storing dust in the hole is arranged between the scraper 10 and the layer plate 11 in the connecting sleeve 1, so that the dust on the inner wall of the hole is squeezed into the storage cavity inside the connecting sleeve 1, and the dust is removed as the positioning plate 6 slides out; and the interior of the connecting sleeve 1 after cleaning the dust is fixedly connected to a plastic fixing pipe 2 equipped with steel bars.

[0034] Specifically, in this embodiment, the connection sleeve 1 is designed as a hollow structure, the scraper 10 and the layer plate 11 are located at the open end of the connection sleeve 1, and can rotate around the axial direction of the connection sleeve 1 under external drive, the push rod 8 is connected to the push plate 5, the positioning plate 6, the scraper 10 and the layer plate 11 in sequence, the linkage rod 9 is connected to the positioning plate 6, the scraper 10 and the layer plate 11 in sequence, and the push rod 8 and the linkage rod 9 transmit force and control the movement of the scraper 10 / layer plate 11. In addition, the spring 7 interposed between the push plate 5 and the positioning plate 6 can ensure the balance of force and stable positioning during the push and pull process; the storage cavity is surrounded by the scraper 10 and the layer plate 11, and is used to collect dust accumulated on the inner wall of the hole. The insertion stage is to place the connection 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 pushed manually or mechanically, the spring 7 is compressed, and the push rod 8 is linked with the linkage rod 9 to drive the scraper 10 and the layer plate 11 to rotate and clean close to the hole wall. During the storage stage, the dust is squeezed into the storage cavity by the scraper 10 and retained as the positioning plate 6 slides. During the emptying stage, the positioning plate 6 moves outward, and the dust moves with the positioning plate 6 and completely leaves the hole. Therefore, in the structure of the present invention, the scraper 10 and the layer plate 11 precisely fit the hole wall to ensure that no dust remains. The push-pull design is simple and intuitive, which is convenient for on-site construction personnel to operate. In addition, it uses high-toughness plastic, which is durable and not easy to damage the hole wall. The plastic connector provided by the present invention is not only suitable for cleaning holes before embedding reinforcement in the filling wall, but also has the characteristics of high efficiency, convenience and environmental protection.

[0035] In this embodiment, refer to Figure 2 One end of the plastic fixing tube 2 is provided with a limiting ring 3 whose outer diameter is larger than that of the connecting sleeve 1. The existence of the limiting ring 3 effectively prevents the plastic fixing tube 2 from accidentally penetrating too deep into the hole, ensures construction safety and accuracy, and ensures that the plastic fixing tube 2 can accurately reach the preset depth when implanted in the hole, thereby improving the accuracy and efficiency of the rebar implantation 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 displacement of the plastic fixing tube 2 during subsequent construction. In addition, the setting of the limiting ring 3 indirectly avoids damage to the edge of the hole caused by forceful insertion and maintains the integrity of the wall.

[0036] In this embodiment, refer to Figure 2The plastic fixing tube 2 is provided with bevel teeth 4 inside. The existence of the bevel teeth 4 increases the friction between the plastic fixing tube 2 and the inner wall of the hole, significantly improves the pull-out strength of the overall structure, and ensures that the anchor bar is more firmly planted. The surface of the bevel teeth 4 is an inclined surface and the inclined surface faces the limit ring 3. The design of the inclined surface facing the limit ring 3 means that during the anchor bar planting process, once subjected to reverse force, the bevel teeth 4 will bite the hole wall more tightly to prevent loosening or pulling out, thereby enhancing the reliability of the structure.

[0037] Reference Figure 3 The inner surface of the connecting sleeve 1 is provided with an internal thread near the limit ring 3, and the outer surface of the plastic fixing tube 2 is provided with an external thread matching the internal thread. The matching of the internal thread and the external thread ensures the precise alignment of the connecting sleeve 1 and the plastic fixing tube 2, thereby improving the accuracy of the rebar planting operation. The bite action of the thread provides a solid physical connection, which can keep the connection stable and avoid loosening even in complex construction environments. The threaded connection allows for quick assembly and disassembly, facilitates adjustment and maintenance during construction, and improves work efficiency. In addition, the threaded connection plays a sealing role to a certain extent, reduces the influence of dust or other impurities inside the hole, and keeps the rebar planting area clean.

[0038] In this embodiment, refer to Figure 2 , one end of the connecting sleeve 1 is provided with an inclined surface, and the inclined surface design greatly reduces the resistance when the connecting sleeve 1 is inserted into the hole, ensuring a smooth and unobstructed entry process; one end of the inclined surface is a ring-shaped tip, which facilitates the insertion of the connecting sleeve 1 into the hole, improves the construction accuracy, and ensures that the connector is correctly positioned. The inclined surface and the tip structure reduce the friction with the hole wall, prolong the service life of the connecting sleeve 1, and protect the hole wall from damage. In addition, the inclined surface naturally guides the material inside the hole (such as residual dust) to flow into the connecting sleeve 1, improving the cleaning efficiency.

[0039] In this embodiment, refer to Figure 3 The outer diameter of the scraper 10 is smaller than the inner diameter of the connecting sleeve 1, in order to ensure that it can rotate flexibly in the connecting sleeve 1 to perform cleaning tasks, 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 wall of the hole when the scraper 10 rotates, achieving a more thorough cleaning effect, while avoiding the increase in 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 a balance between efficient cleaning and structural compactness, achieving deep cleaning while maintaining the structural integrity of the connecting sleeve 1.

[0040] Reference Figure 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, and at the same time reduces 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 operation 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 infill wall provided by the present invention is as follows: Figure 1-Figure 5 , including the following steps:

[0042] Step 1: Drill holes in the wall to a predetermined depth;

[0043] Step 2: Insert the connecting sleeve 1 into the hole, and the powder in the hole is squeezed into the connecting sleeve 1. By pushing the push plate 5 to move relative to the positioning plate 6, the push plate 5 squeezes the spring 7, drives the push rod 8 to move, and 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, and the scraper 10 and the layer plate 11 are tilted to pass through the powder pile;

[0044] Step 3: Release the push plate 5, the scraper plate 10 and the layer plate 11 become vertical, and pull the positioning plate 6 outward, so that the scraper plate 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 flame until it softens, insert the steel bar into the plastic fixing tube 2, wait for the plastic fixing tube 2 to cool, insert the plastic fixing tube 2 into the connecting sleeve 1, and 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 are not intended to limit the implementation methods and protection scope of the present invention. Those skilled in the art 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.
