Description

Technical Field

[0001] The invention belongs to the technical field of construction engineering, and in particular relates to a highly stable assembled concrete connection node structure. Background Art

[0002] Prefabricated concrete connection node structure refers to the key part between prefabricated concrete components (such as prefabricated beams, prefabricated columns, etc.) that are assembled into an overall structural system on site through specific connection methods and construction measures;

[0003] At present, the traditional prefabricated concrete connection node structure is to put the steel cage into the column, and then use the lifting equipment to insert the prefabricated beam into the connection groove. After the installation is completed, concrete will be injected into the column to form a whole.

[0004] However, during the process of inserting the precast beam into the connection groove, the connection groove itself needs to bear huge pressure and weight. This initial support state is only temporary, because the next construction step also includes injecting concrete into the column. The concrete pouring process is not only to fill the space, but more importantly to firmly combine the steel cage, precast beam and column to form an integral structure. However, as the concrete is gradually injected, the load on the entire structure is also increasing. This increase in load, especially on the basis that the precast beam has already exerted a certain pressure on the connection groove, may further aggravate the stress concentration phenomenon of the connection groove and the surrounding structure, which may cause the integrity of the structure to be damaged and the overall stability of the node to be reduced. Summary of the invention

DETAILED DESCRIPTION

[0028] 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.

[0029] like Figures 1 to 7 As shown, the present invention provides a highly stable assembled concrete connection node structure, comprising a column 1, the outer surface of the column 1 is provided with four connection grooves 2, the interior of the four connection grooves 2 is plugged with a prefabricated beam body 3, and the interior of the column 1 is provided with a steel cage 12;

[0030] A supporting mechanism is arranged at the bottom end of the connecting groove 2, and the supporting mechanism includes a fixed shell 4, which is arranged at the bottom end of the connecting groove 2, and a spring 5 is fixedly installed inside the fixed shell 4, and a connecting block 6 located inside the connecting groove 2 is fixedly installed on the top of the spring 5, and a mounting rod 8 is fixedly installed on one side of the fixed shell 4, and a rotating rod 9 is rotatably connected inside the mounting rod 8, and a hinge plate 7 located inside the rotating rod 9 is fixedly installed at the bottom end of the connecting block 6, and a supporting groove 10 is arranged at the bottom end of the surface of the precast beam body 3, and a hinge block 11 located inside the rotating rod 9 is fixedly installed at the bottom end of the supporting groove 10.

[0031] The above scheme is adopted: the operator inserts the steel cage 12 into the interior of the column 1, and then uses the lifting equipment to insert the precast beam body 3 into the interior of the connecting groove 2. When the precast beam body 3 enters the interior of the connecting groove 2, it will contact one side of the connecting block 6 and squeeze the connecting block 6 to move downward. When the connecting block 6 descends, the spring 5 will be compressed, and then the connecting block 6 will drive the hinge plate 7 to move inside the rotating rod 9, and will drive the rotating rod 9 to rotate. During the rotation of the rotating rod 9, the hinge block 11 will also slide inside the rotating rod 9, and the rotating rod 9 will push the hinge block 11 and the support groove 10 to move toward the surface of the precast beam body 3, and then the support groove 10 will be sleeved on the surface of the precast beam body 3, thereby supporting the precast beam body 3. After the support is completed, concrete can be injected into the interior of the column 1 to form a whole. Finally, the precast beam body 3 squeezes the connecting block 6 so that the support groove 10 supports the precast beam body 3, thereby enhancing the integrity of the structure, helping the structure to better withstand external loads, and improving the overall stability of the node.

[0032] like Figure 5 , Figure 6 and Figure 7 As shown, it also includes: a positioning mechanism, which is arranged at the top of the connecting groove 2, the positioning mechanism includes a mounting plate 19, the mounting plate 19 is fixedly connected to the top of the connecting groove 2, and the number of the mounting plates 19 is four, four protective shells 14 are fixedly installed on one side of the four connecting grooves 2, a connecting plate 13 is fixedly installed on one side of the hinge plate 7, and four gears 15 are rotatably connected inside the four protective shells 14, and a toothed plate 16 located inside the protective shell 14 is fixedly installed on the top of the connecting plate 13, and the toothed plate 16 and the gear 15 are fixedly installed on the top of the connecting plate 13. 5 are meshed with each other, a screw rod 17 on one side of a mounting plate 19 is fixedly installed on one side of the gear 15, an extrusion block 18 is threadedly sleeved on the surface of the screw rod 17, a square shell 20 is fixedly installed on one side of the mounting plate 19, a spring 21 is fixedly installed inside the square shell 20, a square rod 22 located inside the square shell 20 is fixedly installed on one end of the spring 21, four positioning plates 23 are fixedly installed on one side of the square rod 22 close to the surface of the steel cage 12, and four connecting blocks 28 are fixedly installed on the bottom ends of the four positioning plates 23.

[0033] The above scheme is adopted: through the design of the positioning mechanism, when the hinge plate 7 descends, the connecting plate 13 will be linked to descend, and the connecting plate 13 will drive the tooth plate 16 to slide inside the protective shell 14. Since the tooth plate 16 is meshed with the gear 15, the moving tooth plate 16 will drive the gear 15 to rotate, and the gear 15 will drive the screw rod 17 to rotate. Since the screw rod 17 is threadedly connected with the extrusion block 18, when the screw rod 17 rotates, the extrusion block 18 will move on the surface of the screw rod 17, and then one side of the extrusion block 18 will contact one side of the connecting block 28, and then it will push the connecting block 28 to move, and the connecting block 28 will drive the four positioning plates 23 The square rod 22 will move toward the surface of the steel cage 12, and when the positioning plate 23 moves, the square rod 22 will move with it, and then the spring 21 inside the square shell 20 will be stretched, and then the surface of the positioning plate 23 will contact the surface of the steel cage 12 and push the steel cage 12 to move, and when the four positioning plates 23 contact the steel cage 12 at the same time, the steel cage 12 will be fixed at the center inside the column 1, and finally the positioning plate 23 will fix the steel cage 12 at the center inside the column 1 through the hinged plate 7 linking the connecting plate 13, thereby avoiding the position of the steel cage 12 from shifting when pouring concrete, thereby improving the overall quality of the concrete structure.

[0034] like Figure 6 and Figure 7 As shown, a limit ring 24 is fixedly installed on the surface of the screw rod 17, and one side of the limit ring 24 contacts one side of the protective shell 14, a limit groove 25 is opened on one side of the mounting plate 19, and the internal sliding connection of the limit block 26 is connected to the limit block 26, and one end of the limit block 26 is fixedly connected to one side of the extrusion block 18.

[0035] The above scheme is adopted: through the design of the limit ring 24, when the gear 15 rotates, the limit ring 24 will be driven to rotate. Since one side of the limit ring 24 contacts one side of the protective shell 14, the screw rod 17 can be limited through the cooperation between the gear 15 and the limit ring 24 to avoid the position shifting when the screw rod 17 rotates. Through the design of the limit groove 25 and the limit block 26, when the extrusion block 18 moves, the limit block 26 will be driven to slide inside the limit groove 25. When the limit block 26 moves, the moving direction of the extrusion block 18 can be limited, and it can be ensured that the extrusion block 18 can move normally.

[0036] like Figure 1 , Figure 2 , Figure 3 and Figure 6As shown, a telescopic rod 27 is fixedly installed on one side of the fixed shell 4, and the top of the telescopic rod 27 is fixedly connected to the bottom end of the supporting groove 10, the number of the telescopic rods 27 is two, and the telescopic rods 27 are designed to be laterally symmetrical about the center of the fixed shell 4, a positioning groove 29 is fixedly installed on the bottom end of the connecting groove 2, and positioning blocks 30 located inside the positioning groove 29 are fixedly installed on both sides of the surface of the connecting block 6, and one side of the connecting block 6 is designed as a slope.

[0037] The above scheme is adopted: through the design of the telescopic rod 27, when the rotating rod 9 pushes the supporting groove 10 to move, the telescopic rod 27 will be extended and retracted. During the extension and retraction process, the supporting groove 10 can be limited, thereby ensuring that the supporting groove 10 can be accurately sleeved on the surface of the prefabricated beam body 3. Through the design of the positioning groove 29 and the positioning block 30, when the prefabricated beam body 3 is away from the surface of the connecting groove 2, the compressed spring 5 will push the connecting block 6 to enter the interior of the connecting groove 2 again, and when the connecting block 6 moves, the positioning block 30 will move with it, and then the positioning block 30 will enter the interior of the positioning groove 29, thereby positioning the connecting block 6, ensuring that the inclined surface on one side of the connecting block 6 is on the same horizontal line as the bottom end of the inside of the connecting groove 2, thereby facilitating the moving prefabricated beam body 3 to squeeze the connecting block 6 to move.

[0038] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a fixing hole is opened at the top of the protective shell 14, and the tooth plate 16 can move inside the fixing hole. A square hole is opened on the surface of the fixing shell 4, and the rotating rod 9 and the connecting plate 13 can slide inside the square hole.

[0039] The above scheme is adopted: through the design of the protective shell 14, since a fixing hole is provided at the top of the protective shell 14, when the tooth plate 16 moves up, it will pass through the fixing hole, and the protective shell 14 will not interfere with the movement of the tooth plate 16. Through the design of the fixed shell 4, since a square hole is provided on the surface, when the rotating rod 9 and the connecting plate 13 move, they will slide inside the square hole, and the inner walls of the square hole are in contact with the surfaces of the rotating rod 9 and the connecting plate 13, so when the rotating rod 9 and the connecting plate 13 move, they can be limited.

[0040] like Figure 4 and Figure 6 As shown, the sides opposite to the extrusion block 18 and the connecting block 28 are both designed with inclined surfaces, and the two inclined surfaces are parallel to each other. Both sides inside the support groove 10 are designed with rounded corners, and the inner wall of the support groove 10 fits with the surface of the prefabricated beam body 3.

[0041] The above scheme is adopted: through the design of the extrusion block 18 and the connecting block 28, since the opposite sides of the extrusion block 18 and the connecting block 28 are both designed with inclined surfaces and are parallel to each other, when the extrusion block 18 moves, the resistance between the extrusion block 18 and the connecting block 28 can be reduced, which makes it convenient for the extrusion block 18 to push the connecting block 28 to move. Through the design of the support groove 10, since both sides of the inside of the support groove 10 are designed with rounded corners, it is convenient for the support groove 10 to be sleeved on the surface of the prefabricated beam body 3, and the inner wall of the support groove 10 is in contact with the surface of the prefabricated beam body 3, thereby improving its supporting effect.

[0042] The working principle and use process of the present invention:

[0043] First, the operator can insert the steel cage 12 into the column 1, and then use the lifting equipment to insert the precast beam body 3 into the connection groove 2. When the precast beam body 3 enters the connection groove 2, it will contact one side of the connection block 6 and squeeze the connection block 6 to move downward. When the connection block 6 descends, the spring 5 will be compressed, and then the connection block 6 will drive the hinge plate 7 to move inside the rotating rod 9. When the hinge plate 7 moves, it will link the connection plate 13 and the tooth plate 16 to descend, and the tooth plate 16 will drive the gear 15 and the screw rod 17 to rotate. When the extrusion block 18 moves on the surface of the screw rod 17, one side of the extrusion block 18 contacts one side of the connecting block 28 and pushes the connecting block 28 to move. The connecting block 28 drives the four positioning plates 23 to move toward the surface of the steel cage 12. When the positioning plates 23 move, the spring 21 inside the square shell 20 is stretched. Then the surface of the positioning plates 23 contacts the surface of the steel cage 12 and pushes the steel cage 12 to move. When the four positioning plates 23 contact the steel cage 12 at the same time, the steel cage 12 is fixed at the center inside the column 1.

[0044] At the same time, the hinge plate 7 will drive the rotating rod 9 to rotate. During the rotation of the rotating rod 9, the hinge block 11 will also slide inside the rotating rod 9, and the rotating rod 9 will push the hinge block 11 and the support groove 10 to move toward the surface of the precast beam body 3, and then the support groove 10 will support the precast beam body 3. After the support and fixation are completed, concrete can be injected into the interior of the column 1 to form a whole, and finally complete the operation process.
