Description

Technical Field

[0001] The invention relates to the technical field of prefabricated component installation nodes, in particular to an installation node and method for a support hinged concrete prefabricated component. Background Art

[0002] Precast concrete components with hinged supports, such as precast concrete stair slabs and precast concrete stadium stands, are designed with a variety of lifting rings or nails and installation holes for the convenience of demoulding, lifting and installation. However, there are problems such as low production efficiency, low installation accuracy, difficulty in quality assurance and high construction cost. Figure 1 The precast concrete component shown comprises a precast component 1 and a lifting ring 2 detachably connected to the upper side thereof.

[0003] In the face of Figure 2 In the installation environment, when the installation surface 3 is in an inclined state, that is, the installation surface 3 has an inclination angle 4, because the center of gravity of the prefabricated component 1 is downward and in a horizontal state under the action of the lifting ring, the prefabricated component 1 needs to be embedded in the supporting frame 5. The existing installation method needs to continuously use external auxiliary limiting tools to achieve installation, which is troublesome and cumbersome. If the concrete prefabricated component is also kept in a corresponding inclined state during installation, it can facilitate the rapid installation of the concrete prefabricated component.

[0004] However, due to the limitations of existing installation nodes, such as ring-type installation nodes, precast concrete components are often unable to freely adjust their left and right tilt states. Under the action of the center of gravity, there is always a driving force for the precast concrete components to restore the horizontal state, and only the position or front and rear tilt states of the precast concrete components can be adjusted.

[0005] Therefore, in order to solve the above problems, an installation node and method for support hinged precast concrete components are proposed. Summary of the invention

[0006] The purpose of the present invention is to provide an installation node and method for a support hinged precast concrete component. When facing an installation environment that is tilted left or right, the existing installation method requires continuous use of external auxiliary limiting tools to achieve installation, which is troublesome and cumbersome. The installation node in the present invention can keep the precast concrete component in a corresponding tilted state during installation, thereby facilitating the rapid installation of the precast concrete component.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: the installation node of the support hinged concrete prefabricated component includes a hollow ball fixed at the center of the prefabricated component, the outer side of the hollow ball is fixedly connected with a connecting rib, the connecting rib is diffusely distributed on the outer side of the hollow ball, the connecting rib is embedded in the inner side of the prefabricated component, the connecting rib is used to increase the structural strength of the prefabricated component, the inner side of the hollow ball is rotatably connected with a rotating ball, the inner center of the rotating ball can be spirally connected with a connecting column, the top surface of the rotating ball is also provided with two positioning holes, the rotating ball can be fixed through the positioning holes, and the top of the connecting column is fixedly connected with a lifting ring;

[0008] The lower side of the connecting column is connected to a connecting rod by a hinge rotation. The number of the connecting rods is 4 and they are evenly distributed on the outer side of the connecting column. After the bottom end of the connecting column rotates to the end on the inner side of the rotating ball, the four connecting rods can be respectively arranged in the front, rear, left and right directions of the prefabricated component;

[0009] A piston plate is fixedly connected to the connecting rod toward the outside of the prefabricated component, an outer side of the piston plate is slidably connected to an outer cylinder, a bottom end of the outer cylinder away from the connecting rod is rotatably connected to a ball, the inner side of the connecting rod is hollow, and the connecting rod is connected to a liquid outlet toward the outside of the prefabricated component. When liquid flows out of the liquid outlet, the liquid in the outer cylinder increases, and the outer cylinder can move toward the outside of the prefabricated component, thereby realizing the adjustment of the inclination angle of the prefabricated component.

[0010] Under the above settings, the installation nodes in the present invention can keep the precast concrete components in a corresponding tilted state during installation, which facilitates the rapid installation of the precast concrete components. The present invention only has one lifting ring through the rotating ball and the connecting column, which can reduce the steps of using and connecting one lifting ring compared to the two lifting rings in the prior art, thereby omitting the operation steps.

[0011] The prefabricated component in the present invention is supported by a central hollow ball and a rotating ball, and the rotating ball is spirally connected to an external connecting column, so that the prefabricated component can rotate around the rotating ball. The present invention adds a counterweight to one side of the rotatably connected prefabricated component, thereby realizing convenient adjustment of the inclination to one side and the degree of inclination, which is convenient for rapid installation of an installation surface with an inclined angle.

[0012] During installation, the rotating ball is fixed by inserting the positioning pin into the positioning hole, and the connecting column is screwed into the inner side of the rotating ball. After the bottom end of the connecting column is rotated to the end inside the rotating ball, the four connecting rods are respectively arranged in the front, rear, left and right directions of the prefabricated component;

[0013] In the tilting direction, the liquid in the two outer cylinders increases, and the outer cylinders can move to the outside of the prefabricated component. However, due to the large difference in the amount of liquid increase in the two outer cylinders, the weight and walking distance in the outer cylinders will deviate. As the liquid increases, the weight in the outer cylinder is heavier than that in the other outer cylinder, and the walking length of the outer cylinder is longer, the prefabricated component will tilt more.

[0014] As the installation node of the support hinged precast concrete component of the present invention, preferably, the vertical distance from the hinge point of the outer tube on the connecting column to the upper surface of the precast component is greater than the outer edge diameter of the outer tube.

[0015] This arrangement enables the hinge point of the outer tube on the connecting column to be higher than the outer tube, making it easier for the gravity of the outer tube to be applied to the prefabricated component;

[0016] Preferably, as the installation node of the support hinged concrete prefabricated component of the present invention, a cylinder is fixedly connected to the outer side of the upper end of the connecting column, a circular ring plate is slidably connected to the inner side of the cylinder, the inner side of the cylinder is filled with balancing liquid, four liquid outlet holes are provided at the bottom end of the cylinder, the outlet ends of the liquid outlet holes are connected to a hose, the bottom end of the hose is connected to the inner side of the connecting rod, a swivel is slidably connected to the inner side of the bottom end of the cylinder, and two movable openings are provided on the swivel.

[0017] The circular plate in the present invention has enough downward space and will not be blocked by the gears at the lower position;

[0018] As the installation node of the support hinged concrete prefabricated component of the present invention, preferably, one of the movable openings is arranged near the central symmetric point of the other movable opening on the swivel, and when the circular ring plate of the swivel moves downward, the balancing weight liquid in the cylinder is compressed, so that the balancing weight liquid can enter the inner side of the outer cylinder through the movable opening, the corresponding liquid outlet, the hose, the connecting rod and the liquid outlet.

[0019] Preferably, as the installation node of the support hinged precast concrete component of the present invention, the inner side of the cylinder is rotatably connected to a knob, and the knob is fixedly connected to a gear on the side close to the connecting column. The top of the swivel is in the shape of a gear ring, and the top of the swivel is meshed with the gear, and the position of the swivel is changed by rotating the gear.

[0020] When the prefabricated component needs to be tilted, the knob is turned to rotate the rotating ring so that the movable opening is connected with the liquid outlet hole on the side that needs to be tilted. Because one of the movable openings is arranged near the central symmetric point of the other movable opening on the rotating ring, the overlapping areas of the two movable openings and the two liquid outlet holes on the tilted side will be inconsistent. When the circular ring plate descends, the liquid flow entering the corresponding outer cylinder will be inconsistent, so that the weight on both sides of the tilting direction is inconsistent, so as to achieve the tilting of the prefabricated component. The tilting degree can be adjusted according to the descending time of the circular ring plate. The longer the descending time, the greater the weight difference between the two corresponding outer cylinders, so as to achieve the adjustment of the tilting amount.

[0021] As the installation node of the support hinged precast concrete component of the present invention, the cylinder is preferably made of non-metallic material, the outer side of the cylinder is rotatably connected with a connecting ring, the corresponding surfaces of the connecting ring and the swivel are made of magnetic material, the connecting ring and the swivel form a magnetic attraction synchronization structure, and the connecting ring can rotate with the rotation of the swivel.

[0022] As the installation node of the support hinged concrete precast component of the present invention, preferably, the connecting ring is engraved with a reference point, and the surface of the cylinder is engraved with scale lines, and the position of the movable opening on the swivel is obtained by observing the scale lines and the reference points.

[0023] Preferably, as the installation node of the support hinged concrete precast component of the present invention, the outer side of the upper end of the connecting column is fixedly connected to a connecting plate, the inner side of the connecting plate is spirally connected to a screw, the bottom end of the screw is rotatably connected to the top end of the circular ring plate, and the lifting movement of the circular ring plate in the cylinder is realized by the rotation of the screw, the inner side of the connecting plate is slidably connected to a limit rod, and the bottom end of the limit rod is fixedly connected to the top end of the circular ring plate.

[0024] Preferably, as an installation node for the support hinged concrete precast component of the present invention, a limiting groove is provided at the bottom end of the rotating ball, a sliding groove is provided on the inner side of the bottom end of the connecting column, a block is slidably connected to the inner side of the sliding groove, a spring is provided on the inner side of the sliding groove, two ends of the spring are respectively fixedly connected to one end of the block and the inner end of the sliding groove, the block can slide outward into the inner side of the limiting groove, the top end of the connecting column is slidably connected to a pull block, the bottom end of the pull block is fixedly connected to a pull rope, the other end of the pull rope passes through the inner side of the connecting column and is fixedly connected to the other end of the block, and the block can be pulled out of the limiting groove by pulling the pull block.

[0025] Under the above settings, components such as the card block are used to prevent the connection column from sliding and rotating under force. When installing the connection column, the pull block can be pulled to hide the pull block at the bottom end of the connection column, and then the spiral connection of the connection column can be achieved. After installation, the pull block is released, and the card block can slide outward into the inner side of the limit groove to achieve limit.

[0026] A method for using an installation node of a support hinged concrete prefabricated component, the steps of which are:

[0027] Step 1: Installation: insert the positioning pin into the positioning hole to fix the rotating ball, screw the connecting column into the inner side of the rotating ball, and after the bottom end of the connecting column is rotated to the end inside the rotating ball, the four connecting rods are respectively arranged in the front, rear, left and right directions of the prefabricated component;

[0028] Step 2: Adjustment. When the prefabricated component needs to be tilted, turn the knob to rotate the rotating ring so that the movable opening is connected with the liquid outlet hole on the side that needs to be tilted. Because one of the movable openings is arranged near the central symmetry point of the other movable opening on the rotating ring, the overlapping areas of the two movable openings and the two liquid outlet holes on the tilted side will be inconsistent. When the circular ring plate moves downward, the liquid flow rate entering the corresponding outer cylinder will be inconsistent, so that the weight on both sides of the direction that needs to be tilted is inconsistent, thereby realizing the tilting of the prefabricated component. The degree of tilt can be adjusted according to the descending time of the circular ring plate. The longer the descending time, the greater the weight difference between the two corresponding outer cylinders, thereby realizing the adjustment of the tilt amount.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. The support is hinged to the installation node of the precast concrete component. Through the installation node in the present invention, the precast concrete component can be kept in a corresponding tilted state during installation, which facilitates the rapid installation of the precast concrete component. The present invention only has one lifting ring through the rotating ball and the connecting column. Compared with the two lifting rings in the prior art, it can reduce the steps of using and connecting one lifting ring, thereby omitting the operation steps.

[0031] 2. The support is an installation node of a hinged concrete prefabricated component. The prefabricated component in the present invention is supported by a hollow ball and a rotating ball in the center. The rotating ball is spirally connected to an external connecting column, so that the prefabricated component can rotate around the rotating ball. The present invention adds a counterweight to one side of the rotatably connected prefabricated component, thereby realizing convenient adjustment of the inclination to one side and the degree of inclination, and facilitating rapid installation of an installation surface with an inclination angle. During installation, the rotating ball is fixed by inserting a locating pin into the locating hole, and the connecting column is spirally rotated to the inner side of the rotating ball. After the bottom end of the connecting column is rotated to the end on the inner side of the rotating ball, the four connecting rods are respectively arranged in the front, rear, left and right directions of the prefabricated component.

[0032] 3. The support is hinged on the installation node of the concrete precast component. In the inclined direction, the liquid in the two outer cylinders increases, and the outer cylinders can move to the outside of the precast component. However, due to the large difference in the amount of liquid increase in the two outer cylinders, the weight and travel distance in the outer cylinders will deviate. As the liquid increases, the weight in the outer cylinder is heavier than that in the other outer cylinder, and the travel length of the outer cylinder is longer, the precast component will tilt more.

[0033] 4. The support is hinged at the installation node of the concrete precast component. When the precast component needs to be tilted, the knob is turned to rotate the swivel to connect the movable opening with the liquid outlet hole on the side that needs to be tilted. Because one of the movable openings is arranged near the central symmetry point of the other movable opening on the swivel, the overlapping areas of the two movable openings and the two liquid outlet holes on the tilted side will be inconsistent. When the circular ring plate descends, the liquid flow rate entering the corresponding outer cylinder will be inconsistent, so that the weight on both sides of the direction that needs to be tilted is inconsistent, thereby realizing the tilting of the precast component. The degree of tilting can be adjusted according to the descending time of the circular ring plate. The longer the descending time, the greater the weight difference between the two corresponding outer cylinders, thereby realizing the adjustment of the tilting amount.

DETAILED DESCRIPTION

[0049] 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.

[0050] Example 1, please refer to Figure 1-Figure 14 , the present invention provides a technical solution:

[0051] The mounting node of the support hinged concrete prefabricated component includes a hollow ball 6 fixed at the center of the prefabricated component 1, a connecting rib 8 is fixedly connected to the outside of the hollow ball 6, the connecting rib 8 is diffusely distributed on the outside of the hollow ball 6, the connecting rib 8 is embedded in the inside of the prefabricated component 1, and the connecting rib 8 is used to increase the structural strength of the prefabricated component 1. The inside of the hollow ball 6 is rotatably connected to a rotating ball 7, and the inner center of the rotating ball 7 can be spirally connected to a connecting column 17. The top surface of the rotating ball 7 is also provided with two positioning holes 26, and the rotating ball 7 can be fixed through the positioning holes 26. The top of the connecting column 17 is fixedly connected to a lifting ring 2;

[0052] The lower side of the connecting column 17 is connected to a connecting rod 9 by a hinge rotation. There are four connecting rods 9, which are evenly distributed on the outer side of the connecting column 17. After the bottom end of the connecting column 17 rotates to the end on the inner side of the rotating ball 7, the four connecting rods 9 can be respectively arranged in the front, rear, left and right directions of the prefabricated component 1;

[0053] The connecting rod 9 is fixedly connected to a piston plate 24 in the direction toward the outside of the prefabricated component 1, and the outer side of the piston plate 24 is slidably connected to an outer cylinder 10. The bottom end of the outer cylinder 10 on the side away from the connecting rod 9 is rotatably connected to a ball 11. The inner side of the connecting rod 9 is hollow, and the connecting rod 9 is connected to a liquid outlet 25 in the direction toward the outside of the prefabricated component 1. When liquid flows out of the liquid outlet 25, the liquid in the outer cylinder 10 increases, and the outer cylinder 10 can move toward the outside of the prefabricated component 1, thereby realizing the adjustment of the inclination angle of the prefabricated component 1.

[0054] Under the above settings, the installation nodes in the present invention can keep the precast concrete components in a corresponding tilted state during installation, which facilitates the rapid installation of the precast concrete components. The present invention only has one lifting ring 2 through the rotating ball 7 and the connecting column 17, which can reduce the steps of using and connecting one lifting ring 2 compared to the two lifting rings in the prior art, thereby omitting the operation steps.

[0055] The prefabricated component 1 in the present invention is supported by a central hollow ball 6 and a rotating ball 7, and the rotating ball 7 is spirally connected to an external connecting column 17, so that the prefabricated component 1 can rotate around the rotating ball 7. The present invention adds a counterweight to one side of the rotatably connected prefabricated component 1, thereby realizing convenient adjustment of the inclination to one side and the degree of inclination, and facilitating rapid installation of the installation surface 3 with an inclination angle 4;

[0056] During installation, the rotating ball 7 is fixed by inserting the positioning pin into the positioning hole 26, and the connecting column 17 is screwed into the inner side of the rotating ball 7. After the bottom end of the connecting column 17 is rotated to the end inside the rotating ball 7, the four connecting rods 9 are respectively arranged in the front, rear, left and right directions of the prefabricated component 1;

[0057] In the tilting direction, the liquid in the two outer cylinders 10 increases, and the outer cylinder 10 can move to the outside of the prefabricated component 1. However, due to the large difference in the amount of liquid increase between the two outer cylinders 10, the weight and travel distance in the outer cylinder 10 will deviate. As the liquid increases, when the weight in the outer cylinder 10 is heavier than that in the other outer cylinder 10 (the counterweight increases), and the travel length of the outer cylinder 10 is longer (the power arm increases), the prefabricated component 1 will tilt more.

[0058] Specifically, the vertical distance from the hinge point of the outer cylinder 10 on the connecting column 17 to the upper surface of the prefabricated component 1 is greater than the outer edge diameter of the outer cylinder 10 .

[0059] This arrangement enables the hinge point of the outer cylinder 10 on the connecting column 17 to be higher than the outer cylinder 10 , so that the gravity of the outer cylinder 10 is applied to the prefabricated component 1 ;

[0060] Specifically, a cylinder 21 is fixedly connected to the outer side of the upper end of the connecting column 17, a circular ring plate 16 is slidably connected to the inner side of the cylinder 21, the inner side of the cylinder 21 is filled with a counterweight liquid, four liquid outlet holes 29 are provided at the bottom end of the cylinder 21, the outlet end of the liquid outlet hole 29 is connected to a hose 12, the bottom end of the hose 12 is connected to the inner side of the connecting rod 9, a swivel 28 is slidably connected to the inner side of the bottom end of the cylinder 21, and two movable openings 30 are provided on the swivel 28.

[0061] The circular plate 16 of the present invention has enough downward space and will not be blocked by the gear 27 at the lower position;

[0062] Specifically, one of the movable openings 30 is arranged near the central symmetrical point of the other movable opening 30 on the swivel 28. When the annular plate 16 of the swivel 28 moves downward, the counterweight liquid in the cylinder 21 is compressed, so that the counterweight liquid can enter the inner side of the outer cylinder 10 through the movable opening 30, the corresponding liquid outlet 29, the hose 12, the connecting rod 9 and the liquid outlet 25.

[0063] Specifically, the inner side of the cylinder 21 is rotatably connected to a knob 18, and a gear 27 is fixedly connected to the side of the knob 18 close to the connecting column 17. The top of the swivel 28 is in the shape of a toothed ring, and the top of the swivel 28 is meshed with the gear 27. The position of the swivel 28 is changed by rotating the gear 27.

[0064] See also Figure 11-Figure 14 When the prefabricated component 1 needs to be tilted, the knob 18 is turned to rotate the rotating ring 28 so that the movable opening 30 is connected with the liquid outlet hole 29 on the side that needs to be tilted. Because one of the movable openings 30 is arranged near the central symmetric point of the other movable opening 30 on the rotating ring 28, the overlapping areas of the two movable openings 30 and the two liquid outlet holes 29 on the tilted side will be inconsistent. When the circular ring plate 16 moves downward, the liquid flow rate entering the corresponding outer cylinder 10 will be inconsistent, so that the weight on both sides of the tilting direction is inconsistent, and the tilting of the prefabricated component 1 is realized. The tilting degree can be adjusted according to the descending time of the circular ring plate 16. The longer the descending time, the greater the weight difference between the two corresponding outer cylinders 10, thereby realizing the adjustment of the tilting amount.

[0065] Specifically, the cylinder 21 is made of non-metallic material, and the outer side of the cylinder 21 is rotatably connected with a connecting ring 23. The corresponding surfaces of the connecting ring 23 and the rotating ring 28 are made of magnetic material. The connecting ring 23 and the rotating ring 28 form a magnetic attraction synchronization structure, and the connecting ring 23 can rotate along with the rotation of the rotating ring 28.

[0066] Specifically, a reference point 19 is engraved on the connecting ring 23 , and scale lines 20 are engraved on the surface of the cylinder 21 . The position of the movable opening 30 on the rotating ring 28 can be obtained by observing the scale lines 20 and the reference point 19 .

[0067] Specifically, the outer side of the upper end of the connecting column 17 is fixedly connected to the connecting disk 13, the inner side of the connecting disk 13 is spirally connected to the screw 22, the bottom end of the screw 22 is rotatably connected to the top end of the circular ring plate 16, and the lifting movement of the circular ring plate 16 in the cylinder 21 is realized by the rotation of the screw 22. The inner side of the connecting disk 13 is slidably connected to the limit rod 14, and the bottom end of the limit rod 14 is fixedly connected to the top end of the circular ring plate 16.

[0068] Example 2: This example is a further improvement of Example 1. Figure 3 and 4 A limiting groove 32 is provided at the bottom end of the rotating ball 7, a sliding groove is provided on the inner side of the bottom end of the connecting column 17, a block 31 is slidably connected to the inner side of the sliding groove, a spring 33 is provided on the inner side of the sliding groove, and the two ends of the spring 33 are respectively fixedly connected to one end of the block 31 and the inner end of the sliding groove, so that the block 31 can slide outward into the inner side of the limiting groove 32, and a pull block 15 is slidably connected to the top end of the connecting column 17, and a pull rope 34 is fixedly connected to the bottom end of the pull block 15, and the other end of the pull rope 34 passes through the inner side of the connecting column 17 and is fixedly connected to the other end of the block 31, and the block 31 can be pulled out of the limiting groove 32 by pulling the pull block 15.

[0069] Under the above setting, the components such as the block 31 are used to prevent the connection column 17 from sliding and rotating under force. When installing the connection column 17, the pull block 15 can be pulled to hide the pull block 15 at the bottom end of the connection column 17, and then the spiral connection of the connection column 17 can be realized. After installation, the pull block 15 is released, and the block 31 can slide outward into the inner side of the limit groove 32 to realize the limit.

[0070] The present invention also discloses a method for using an installation node of a support hinged concrete prefabricated component, the steps of which are:

[0071] Step 1: Installation, insert the positioning pin into the positioning hole 26 to fix the rotating ball 7, screw the connecting column 17 into the inner side of the rotating ball 7, and after the bottom end of the connecting column 17 is rotated to the end inside the rotating ball 7, the four connecting rods 9 are respectively arranged in the front, rear, left and right directions of the prefabricated component 1;

[0072] Step 2: Adjustment. When the prefabricated component 1 needs to be tilted, turn the knob 18 to rotate the rotating ring 28 so that the movable opening 30 is connected with the liquid outlet 29 on the side that needs to be tilted. Because one of the movable openings 30 is arranged near the central symmetric point of the other movable opening 30 on the rotating ring 28, the overlapping areas of the two movable openings 30 and the two liquid outlets 29 on the tilted side will be inconsistent. When the circular ring plate 16 moves downward, the liquid flow rate entering the corresponding outer cylinder 10 will be inconsistent, so that the weight on both sides of the direction that needs to be tilted is inconsistent, thereby realizing the tilting of the prefabricated component 1. The degree of tilting can be adjusted according to the descending time of the circular ring plate 16. The longer the descending time, the greater the weight difference between the two corresponding outer cylinders 10, thereby realizing the adjustment of the tilting amount.

[0073] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
