Description

Technical Field

[0001] This utility model relates to the field of frame connection structures, and more particularly to a reinforced concrete frame connection structure. Background Technology

[0002] With the continuous development of building technology, people have put forward higher requirements for the safety, stability and applicability of buildings. Reinforced concrete frame structures have been widely used in various types of buildings due to their good load-bearing capacity, spatial performance and durability. Therefore, in order to meet the needs of building structure development, it is necessary to continuously study and improve reinforced concrete frame connection structures.

[0003] Current reinforced concrete frame connection structures use traditional sleeve connections. This traditional sleeve connection structure requires repeated calibration of the relative positions of the reinforcing bars using measuring tools during the connection process. Repeated adjustments can cause local deformation of the reinforcing bars, reducing their load-bearing capacity and increasing the installation burden on workers. Moreover, during transportation, traditional sleeves lack effective limiting protection. Under the bumps and vibrations of transport vehicles, the sleeves are prone to collisions and friction with other sleeves or transport vehicles, causing damage to the sleeves and affecting the tightness and strength of subsequent reinforcing bar connections. Therefore, a new reinforced concrete frame connection structure is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a reinforced concrete frame connection structure, which aims to improve the positioning of the reinforcing bars during the connection process and the limiting protection of the sleeve during transportation in the existing technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a reinforced concrete frame connection structure, comprising two reinforcing bars, each reinforcing bar having a cross-shaped groove at its top, and each reinforcing bar having a sleeve threadedly connected to its top. Limiting components are fixedly connected to both sides of each sleeve. A second reinforcing bar is fixedly connected to the top of each sleeve. A cross-shaped locking block is provided at the bottom of each second reinforcing bar. Threaded holes are provided inside both sleeves and reinforcing bars, and sleeves and reinforcing bars are fixedly connected by bolts. A second sleeve is threadedly connected to the top of each second reinforcing bar, and a third reinforcing bar is threadedly connected between the two sleeves.

[0006] As a further description of the above technical solution: the limiting component includes two limiting bases distributed on the left and right, the rear part of the right limiting base is fixedly connected to the surface of the sleeve, and the front part of the right limiting base is fixedly connected to a limiting block.

[0007] As a further description of the above technical solution: the rear part of the limiting base on the left is fixedly connected to a surface of the sleeve, and the front part of the limiting base on the left is fixedly connected to two upper and lower distributed outer shells, and springs are provided inside the two upper and lower distributed outer shells.

[0008] As a further description of the above technical solution: each of the springs has two vertically distributed limiting balls fixedly connected to its bottom, and the two vertically distributed limiting balls are slidably connected inside the outer shell;

[0009] As a further description of the above technical solution: the surface of the limiting block is provided with circular grooves distributed vertically, and the size of the limiting ball matches the size of the circular grooves on the surface of the limiting block.

[0010] As a further description of the above technical solution: a groove is provided in the middle of the limiting base on the left side, and the size of the limiting block matches the groove;

[0011] As a further description of the above technical solution: the second sleeve is configured as a right-angled sleeve, and the material of the second sleeve is galvanized steel;

[0012] As a further description of the above technical solution: the size of the cross-shaped groove opened at the top of the reinforcing bar matches the size of the cross-shaped locking block, and the size of the cross-shaped locking block is smaller than the diameter of the sleeve.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, the cross-shaped locking block at the bottom of the second reinforcing bar and the cross-shaped groove at the top of the first reinforcing bar are precisely matched, so that the workers can quickly complete the initial positioning by aligning the locking block with the groove. There is no need to repeatedly calibrate the relative position of the reinforcing bars with measuring tools, which reduces the position adjustment time during the connection process and avoids local deformation of the reinforcing bars caused by repeated adjustment of the reinforcing bar position.

[0015] 2. In this utility model, during transportation, the transport vehicle bumps and vibrates. Through the cooperation of the limiting base, limiting block, outer shell, spring and limiting ball, the relative rolling between the sleeves is effectively limited, avoiding direct collision between the sleeves, which would damage the sleeves themselves and render them unusable.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, those skilled in the art who have not made any innovative embodiments are all within the protection scope of the present utility model.

[0025] Reference Figure 1 - Figure 3This utility model provides an embodiment of a reinforced concrete frame connection structure, including two reinforcing bars 1. Each reinforcing bar 1 is threadedly connected to a sleeve 2. The sleeve 2 is cylindrical to facilitate the connection of longitudinal reinforcing bars. A second reinforcing bar 3 is fixedly connected to the top of the sleeve 2. A cross-shaped groove is formed at the top of the first reinforcing bar 1, and a cross-shaped locking block 7 is formed at the bottom of the second reinforcing bar 3. The size of the cross-shaped groove at the top of the first reinforcing bar 1 matches the size of the cross-shaped locking block 7 at the bottom of the second reinforcing bar 3. The cross-shaped locking block 7 and the cross-shaped groove ensure complete contact between the first reinforcing bar 1 and the second reinforcing bar 3. Furthermore, the size of the cross-shaped locking block 7 at the bottom of the second reinforcing bar 3 is smaller than the diameter of the sleeve 2, thus ensuring... Sleeve 12 is inserted into the bottom of rebar 23. Both sleeve 12 and rebar 23 have threaded holes inside, and sleeve 12 and rebar 23 are fixedly connected by bolts. When sleeve 12 is inserted into the bottom of rebar 23, the threaded hole inside sleeve 12 is matched and positioned with the threaded hole inside rebar 23. When the two threaded holes are completely overlapped, they are fixedly connected by bolts. Sleeve 24 is threadedly connected to the top of rebar 23. Sleeve 24 is set as a right-angle sleeve. This special-shaped sleeve can easily realize the connection of rebars in different directions, which can meet the needs of rebar connection at different angles in frame structures, increase the flexibility and applicability of the connection structure, and better adapt to complex building structure designs. Both sleeve 1 (2) and sleeve 2 (4) are made of galvanized steel. Galvanized steel is used for rebar sleeves. Its surface zinc layer can form a dense protective film, effectively resisting corrosion, extending the service life of the sleeve, and ensuring the long-term stability of the rebar connection in complex environments. It also has good processing performance and is easy to manufacture sleeves of various specifications to meet different construction needs. The two sleeves 2 (4) are connected by threads with rebar 3 (5). This multi-threaded connection and bolt fixing method makes the connection between the rebars tight and firm, which can effectively transfer stress, improve the overall stability of the reinforced concrete frame connection structure, and enhance its reliability when bearing loads.

[0026] Reference Figure 3 - Figure 6The limiting component 6 includes two left and right distributed limiting bases 61. The limiting bases 61 are designed to fix the sleeve 2 and the limiting component 6. The rear of the right limiting base 61 is fixedly connected to the surface of the sleeve 2, and the front of the right limiting base 61 is fixedly connected to a limiting block 62. The limiting block 62 is made of high-quality carbon steel, which has high strength and good processing performance. It can withstand large external forces, ensuring that the limiting block 62 is not easily deformed or damaged during transportation when faced with collisions and compression between the sleeves 2, effectively maintaining the limiting function. The surface of the limiting block 62 has vertically distributed bead-shaped grooves. The rear of the left limiting base 61 is fixedly connected to the surface of the sleeve 2, and the front of the left limiting base 61 is fixedly connected to two vertically distributed outer shells 63. Both of the two vertically distributed outer shells 63 contain springs 64. The design of the outer shells 63 effectively protects the springs 64 from being squeezed during the transportation of the sleeve 2. Each spring 64 is fixedly connected to two vertically distributed limiting balls 65, and the size of the limiting balls 65 matches the size of the circular grooves on the surface of the limiting block 62. When the sleeve 2 needs to be limited, the limiting balls 65 can be engaged in the circular grooves on the surface of the limiting block 62. The left limiting base 61 has a groove in the middle, and the size of the limiting block 62 matches the groove. When the spring 64 is compressed, the limiting balls 65 move in the opposite direction. At this time, the distance between the two limiting balls 65 is enough for the limiting block 62 to move, and the limiting block 62 is engaged in the groove in the middle of the left limiting base 61, thus completing the limiting effect.

[0027] Working Principle: In reinforced concrete frame connection structures, during actual construction, workers first hold rebar 2 (3) and then precisely align the bottom cross-shaped locking block 7 with the top cross-shaped groove of rebar 1 (1). The cross-shaped locking block 7 and the cross-shaped groove are designed for efficient positioning. Workers can quickly and accurately determine the corresponding positions of rebar 1 and rebar 2 (3) simply by visual observation, without needing any other complex measuring tools or precision instruments. From a construction process perspective, this convenient positioning method directly eliminates the cumbersome measurement and calibration steps of traditional positioning methods, thus greatly saving positioning time and significantly improving construction efficiency. In large-scale construction projects, numerous rebar connection operations require a significant amount of time. The application of this efficient positioning method can significantly shorten the overall construction cycle and reduce the input of manpower and time costs. From the perspective of construction quality, this convenient positioning method avoids repeated adjustments to the position of the rebar, which can cause local deformation of the rebar and reduce its load-bearing capacity. In the transverse rebar connection structure, sleeve 2 4 is used. Sleeve 2 4 is designed with a right angle to facilitate the connection between the transverse rebar 3 5 and the vertical rebar 2 3. On the other hand, in the reinforced concrete frame connection structure, when the transport vehicle is in a bumpy and vibrating state, due to the instability of the vehicle's movement, sleeve 1 2 may collide with each other, causing damage to sleeve 1 2 and affecting the quality of subsequent rebar connections. Therefore, limiting components 6 are set on both sides of sleeve 1 2 to protect sleeve 1 2 during transportation. By using the elasticity of spring 64 and the mechanical cooperation between limiting ball 65 and limiting block 62, sleeve 1 2 is protected during transportation. First, the limiting base 61 fixes the limiting component 6 and the sleeve 2. With the cooperation of the limiting block 62 and the limiting ball 65, a relatively stable limiting space is formed. Multiple sleeves 2 equipped with the limiting component 6 are placed side-by-side or stacked. The cooperation between the limiting block 62 and the limiting ball 65 restricts the relative displacement between the sleeves 2. The bead-shaped groove designed on the surface of the limiting block 62 matches the limiting ball 65. During transportation, the limiting ball 65 is embedded in the groove on the surface of the limiting block 62. Furthermore, the groove in the middle of the left limiting base 61 has a tight fit with the limiting block 62. Simultaneously with the limiting ball 65 embedding in the groove on the surface of the limiting block 62, the limiting block 62 also embeds in the groove in the middle of the left limiting base 61. This cooperation further ensures that the limiting block 62 remains stable during its limiting function. During construction, when the construction workers need to use sleeve 12, they pull the two sleeves 12 with force. Due to the elasticity of spring 64, the limiting ball 65 will move relative to each other, causing the limiting ball 65 to slide out of the groove on the surface of the limiting block 62. At the same time, the limiting block 62 will also slide out of the groove inside the left limiting base 61, thus releasing the limiting effect between the multiple sleeves 12.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
