Description

Technical Field

[0001] This utility model relates to the field of concrete component connection technology, and in particular to a quick connection device for concrete structural components. Background Technology

[0002] Reinforced concrete structural members are the basic load-bearing units of a building or engineering structure, made of both concrete and reinforcing steel. The steel bars are embedded in the concrete, allowing the concrete to primarily bear compressive forces, while the steel bars primarily bear tensile forces. This allows the member to effectively cope with various complex stress states, including bending, tension, shear, and compression. Furthermore, the concrete protects the steel bars from corrosion and the effects of high temperatures and fire.

[0003] When connecting prefabricated concrete structural components, grouting is generally used. This method results in a smaller contact area and slightly inferior connection performance, and it also requires a certain amount of time for alignment during installation. Therefore, a rapid connection device for concrete structural components is proposed to address these issues. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a quick connection device for concrete structure components, which effectively solves the deficiencies of the prior art.

[0005] To achieve the above objectives, one embodiment of this utility model provides a quick connection device for concrete structural components, including a vertical component and a horizontal component. A hollow shell is embedded at the top of the interior of the vertical component. Four guide tubes extending to the side of the vertical component are installed on one side of the hollow shell. A connecting frame is slidably installed inside the hollow shell, and one end of the connecting frame enters the interior of the four guide tubes. A top cover is installed at the top of the hollow shell, and a guide groove is installed in the middle of the top cover. The end of the connecting frame away from the horizontal component protrudes upward and enters the interior of the guide groove. Four protruding blocks are installed at the other end of the connecting frame. A connecting plate is installed on the side of the vertical component near the hollow shell.

[0006] The horizontal component has two guide tubes embedded at its end. The two guide tubes have two round holes on their sides that are adapted to the protrusions. The adjacent sides of the two guide tubes are fitted with bent plates that are adapted to the connecting plate. Hollow plates are slidably installed inside the two guide tubes, and the hollow positions of the two tubes are slidably connected to the outside of the connecting frame.

[0007] Preferably, in any of the above solutions, a protrusion is installed on the side of the vertical member near the connecting plate, and the top surface of the protrusion is in contact with the bottom surface of the horizontal member. This solution facilitates the limiting of the installation of the horizontal member and provides support for the end of the horizontal member. At the same time, it is installed inside the guide flat tube with the hollow plate and snapped into the end position of the connecting frame. The connecting plate is slidably connected with the two bending plates, thereby forming a rigid connection structure and improving the structural strength of the connection.

[0008] Preferably, in any of the above solutions, the edge of the top cover is fixedly connected to the top of the hollow shell by welding. Both the top cover and the hollow shell are made of steel plate. After the vertical component is cast, the hollow shell and the top cover can be stably connected to the vertical component, forming an integral structure with the vertical component. After the horizontal component is connected to the vertical component, it is used for fixed connection, improving the structural strength of the connection position. The top cover seals the top of the hollow shell, preventing concrete from entering the interior of the hollow shell during the casting of the vertical component.

[0009] Preferably, in any of the above solutions, the top of the connecting plate is provided with an angle, and a connecting frame is provided on one side of the bottom of the connecting plate. The connecting frame is embedded inside the vertical member. By using this solution, the thickness of the connecting plate can be reduced. During the hoisting of the horizontal member, it is convenient for the top of the connecting plate to cooperate with two bent plates. The two bent plates are made of steel plates and are L-shaped. One side of the two plates is fixedly connected to the side of the guide flat tube by welding. By sliding connection with the connecting plate, it is convenient to guide the hoisting and installation of the horizontal member and provide accuracy for subsequent coordination.

[0010] Preferably, in any of the above schemes, the two guide tubes are welded together by reinforcing bars. One side of the two guide tubes is flush with the end face of the horizontal member, and the other side of the two guide tubes is fixedly connected to the reinforcing cage inside the horizontal member. This scheme facilitates the fixed connection of the two guide tubes, keeping them relatively parallel. The two guide tubes are also fixedly connected to the reinforcing cage inside the horizontal member, thus forming a stable mechanical structure. Before pouring, the reinforcing cage is prestressed and stretched, so that after the horizontal member solidifies, it has high bending resistance, which facilitates stable support for the upper structure.

[0011] Preferably, in any of the above schemes, the axes of the four circular holes are collinear with the axes of the four guide tubes, and the inner diameters of the four circular holes are the same as the inner diameters of the four guide tubes. This scheme facilitates the alignment of the four guide tubes with the circular holes after the horizontal component is hoisted, making it easier to push the connecting frame to slide. This allows the protrusion to enter the interior of the guide flat tube through the circular holes. After the hollow plate is installed, it can block the protrusion. Later, grout is injected into the interior of the guide flat tube and the hollow shell to form a stable connection structure.

[0012] Preferably, the top ends of the two hollow plates are bent at a 90-degree angle, and both have U-shaped grooves on their top surfaces. The two sides of the two hollow plates are respectively attached to the side of the protrusion and the inner wall of the guide tube. This design facilitates the positioning and blocking of the protrusion. The two hollow plates are made of steel plates, and the bent structure at their ends makes it easy for the operator to tap them, allowing the hollow plates to enter the interior of the guide tube. The U-shaped grooves facilitate the injection of slurry, and the fluidity of the slurry completely fills the interior of the guide tube.

[0013] This utility model has the following advantages:

[0014] 1. This quick-connection device for concrete structural components consists of vertical and horizontal components. Two guide tubes are installed at the ends of the horizontal components, each with a circular hole on its side. Two bent plates are installed on the sides of the guide tubes. A connecting frame and a connecting plate are installed at the top of the vertical component. A protruding block is installed at the end of the connecting frame. During connection, the connecting plate enters between the bent plates, and the protruding block slides with the connecting frame, passing through the circular hole and entering the interior of the guide tube. Simultaneously, a hollow plate slides downwards along the guide tube and is installed between the side of the protruding block and the inner wall of the guide tube, thus forming a quick-connection structure. Grouting is then performed into the guide tube and the hollow shell to complete the fixed connection. The overall structure is simple, easy to operate, and greatly saves connection time, effectively solving the problems existing in the prior art.

[0015] 2. This quick connection device for concrete structural components has a vertical component with a protrusion on its side near the connecting plate. When the horizontal component is installed, the end of the horizontal component can directly rest on the top surface of the protrusion. The connecting plate is slidably connected to the two bent plates, which facilitates the positioning of the horizontal component and provides precise positioning for subsequent installation.

[0023] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0024] like Figures 1 to 6 As shown, a quick connection device for concrete structural components includes a vertical component 1 and a horizontal component 2. A hollow shell 7 is embedded in the top of the vertical component 1. Four guide tubes 11 extending to the side of the vertical component 1 are installed on one side of the hollow shell 7. A connecting frame 4 is slidably installed inside the hollow shell 7, and one end of the connecting frame 4 enters the interior of the four guide tubes 11. The connecting frame 4 is directly inserted into the interior of the hollow shell 7 and placed inside the reinforcing cage before the vertical component 1 is poured. It is connected to the external reinforcing cage by welding to lock the position of the hollow shell 7.

[0025] The top of the hollow shell 7 is fitted with a top cover 13, and a guide groove 5 is fitted in the middle of the top cover 13. The end of the connecting frame 4 away from the horizontal member 2 protrudes upward and enters the interior of the guide groove 5. Four protruding blocks 12 are fitted on the other end of the connecting frame 4. A connecting plate 6 is fitted on the side of the vertical member 1 near the hollow shell 7.

[0026] Two guide tubes 8 are inlaid at the end of the horizontal component 2. Two round holes 9 that are adapted to the protrusion 12 are opened on the side of the two guide tubes 8. Bending plates 10 adapted to the connecting plate 6 are installed on the adjacent side of the two guide tubes 8. Hollow plates 3 are slidably installed inside the two guide tubes 8, and the hollow positions of the two are slidably connected to the outside of the connecting frame 4.

[0027] A protrusion is installed on the side of the vertical member 1 near the connecting plate 6. The top surface of the protrusion is in contact with the bottom surface of the horizontal member 2. As an optional technical solution of this utility model, this facilitates the installation of the horizontal member 2 and provides support for the end of the horizontal member 2. At the same time, it is installed inside the guide flat tube 8 with the hollow plate 3 and is snapped into the end position of the connecting frame 4. The connecting plate 6 is slidably connected with the two bent plates 10, thereby forming a rigid connection structure and improving the structural strength of the connection.

[0028] The edge of the top cover 13 is fixedly connected to the top of the hollow shell 7 by welding. Both the top cover 13 and the hollow shell 7 are made of steel plate. As an optional technical solution of this utility model, after the vertical member 1 is poured, the hollow shell 7 and the top cover 13 can be stably connected to the vertical member 1, so that the two and the vertical member 1 form an integral structure. After the horizontal member 2 is connected to the vertical member 1, it is used for fixed connection to improve the structural strength of the connection position. The top cover 13 seals the top position of the hollow shell 7 to prevent concrete from entering the interior of the hollow shell 7 during the pouring of the vertical member 1.

[0029] The top of the connecting plate 6 is provided with an angle, and a connecting frame is provided on one side of the bottom end of the connecting plate 6. The connecting frame is embedded in the interior of the vertical member 1. As an optional technical solution of this utility model, this makes it easier to reduce the thickness of the connecting plate 6. During the hoisting process of the horizontal member 2, it is easier for the top of the connecting plate 6 to cooperate with the two bent plates 10. The two bent plates 10 are made of steel plates and are L-shaped. One side of the two is fixedly connected to the side of the guide flat tube 8 by welding. By sliding connection with the connecting plate 6, it is easier to guide the hoisting and installation of the horizontal member 2 and provide the accuracy of subsequent cooperation.

[0030] The two guide flat tubes 8 are welded together by steel bars. One side of the two guide flat tubes 8 is flush with the end face of the horizontal member 2, and the other side of the two guide flat tubes 8 is fixedly connected to the steel cage inside the horizontal member 2. As an optional technical solution of this utility model, this makes it easy to fix the two guide flat tubes 8 together and keep them relatively parallel. In addition, the two guide flat tubes 8 are fixedly connected to the steel cage inside the horizontal member 2, thereby forming a stable mechanical structure. Before pouring, the steel cage is prestressed and stretched, so that after the horizontal member 2 is solidified, it has high bending resistance and can provide stable support for the upper structure.

[0031] The axes of the four circular holes 9 are collinear with the axes of the four guide tubes 11, and the inner diameters of the four circular holes are the same as the inner diameters of the four guide tubes 11. As an optional technical solution of this utility model, this makes it easier to align the positions of the four guide tubes 11 and the circular holes 9 after the horizontal component 2 is hoisted, which facilitates the sliding of the connecting frame 4, allowing the protruding block 12 to enter the interior of the guide flat tube 8 through the circular holes 9. After the hollow plate 3 is installed, it is easy to block the protruding block 12. Later, grout is injected into the interior of the guide flat tube 8 and the hollow shell 7 to form a stable connection structure.

[0032] The tops of the two hollow plates 3 are bent at a 90-degree angle, and both of them have U-shaped grooves on their top surfaces. The two sides of the two hollow plates 3 are respectively attached to the side of the protruding block 12 and the inner wall of the guide flat tube 8. As an optional technical solution of this utility model, this makes it easy to limit and block the position of the protruding block 12. The two hollow plates 3 are made of steel plate, and the bending structure at their ends makes it easy for the operator to knock them, so that the hollow plates 3 enter the interior of the guide flat tube 8. The U-shaped grooves facilitate the injection of slurry, and the fluidity of the slurry is used to completely fill the interior of the guide flat tube 8.

[0033] The following steps are required when using this quick-connect device for concrete structural components:

[0034] 1) During installation, drag the connecting bracket 4 into the interior of the hollow shell 7;

[0035] 2) Lift the horizontal component 2 and bring its end close to the top of the vertical component 1;

[0036] 3) The connecting plate 6 is slidably connected to the two bent plates 10, and then the horizontal piece 2 is slowly lowered and comes into contact with the protrusion;

[0037] 4) Use a tool to enter the interior of the guide slot 5 and push the connecting frame 4 so that the protrusion 12 at the end of the connecting frame 4 enters the interior of the guide flat tube 8 along the guide tube 11 and the round hole 9.

[0038] 5) Insert the hollow plate 3 into the interior of the guide tube 8 and push it downwards so that the hollow plate 3 enters between the side of the protrusion 12 and the inner wall of the guide tube 8.

[0039] In summary, during use, the vertical component 1 and the horizontal component 2 are configured. Two guide tubes 8 are installed at the end of the horizontal component 2, and both have round holes 9 on their sides. Two bent plates 10 are installed on the sides of the guide tubes 8. A connecting frame 4 and a connecting plate 6 are provided at the top of the vertical component 1. A protruding block 12 is installed at the end of the connecting frame 4. During connection, the connecting plate 6 enters between the two bent plates 10, and the protruding block 12 slides with the connecting frame 4, passing through the round holes 9 and entering the interior of the guide tubes 8. Simultaneously, the hollow plate 3 slides downwards along the guide tubes 8 and is installed on the side of the protruding block 12 and the guide tubes 8. The inner walls of the flat tube 8 are connected to form a quick connection structure. Grouting is then injected into the interior of the guide flat tube 8 and the hollow shell 7 to complete the fixed connection. The overall structure is simple and easy to operate, which greatly saves connection time and effectively solves the problems existing in the prior art. Furthermore, by setting a vertical member 1, a protrusion is installed on the side near the connecting plate 6. When the horizontal member 2 is installed, the end of the horizontal member 2 can directly rest on the top surface of the protrusion. The connecting plate 6 is slidably connected to the two bent plates 10, which facilitates the positioning of the horizontal member 2 and provides precise positioning for subsequent installation.
