[0002] In the field of architecture, beam supports are also called "corbels". There must be a resting structure between the hanging beam and the cantilever of the cantilever system. Usually, the local structure at the cantilever end and the hanging beam end is called "corbel", also known as beam supports. The original function of the beam support is to concentrate the gravity of the beam to the supporting column to reduce the load on the wall. The function of the beam support is to connect the cantilever beam and the hanging beam and transfer the load from the hanging beam. In layman's terms, it is an oblique support between the beam and the column. Therefore, the height of the beam support has been weakened to less than half of the beam height, but it has to transmit larger vertical and horizontal reaction forces, which makes it a weak part of the superstructure, and various situations are prone to occur.

[0015] The present invention has the following beneficial effects:

[0016] 1. The ring beam replacement reinforcement structure of the concrete structure building increases the degree of engagement between the two by cooperating with the internal structure of the building beam and the first supporting structure, and changing the connection method between one side of the right-angle support frame and the inner wall of the building beam. The transverse plug-in combination of the reinforced steel bar and the hollow groove can further provide vertical load-bearing pressure for the right-angle support frame. The upper end of the right-angle support frame fits with the inner wall of the building beam, providing support for the building beam. The interior of the building beam is also filled with concrete, which plays a role in fixing the stability between the two when the right-angle support frame is located inside the casting trough, and increases the connectivity between the beam body and the device, making the device as a whole more coherent. At the same time, the connection strength between the right-angle support frame and the inner wall of the building beam is strengthened, so that the pressure on the side of the building beam is effectively transmitted to the lower end of the building beam. Compared with the previous split structure, the device has a tighter connection and a greater bearing capacity, so that the device can adapt to the transmission of large weights and support effects.

[0017] 2. The ring beam of the concrete structure building is replaced and reinforced. When the edge position of the building beam bears downward pressure, the first support shaft and the second support shaft enable the inner bracket and the outer bracket to have a lever effect, so that the downward pressure of the building beam is transmitted to the upper end position of the outer bracket, and the outer bracket is tilted and transmitted to the toggle pin, and then the lower end of the inner bracket is pushed to one side by the toggle pin. The inner bracket is a nearly right-angle structure. When it is pushed open, the upper end of the inner bracket is pushed up to act on the inner position of the supporting beam, and the inner side of the upper end of the supporting beam is pushed up, and the building beam is pushed up at the same time. The building beam is a right-angle structure. When the inner side is subjected to the lifting force, its edge position will be lifted, so that the internal linkage of the building beam is formed inside the device, and the downward pressure on the edge of the building beam is converted by the outer bracket and the inner bracket into a lifting force on the inner side of the building beam, and a lifting force is provided for the lower end of one side of the building beam to lift up, thereby realizing the support effect on the edge position of one side of the building beam.

[0018] 3. The ring beam support replacement reinforcement structure of the concrete structure building, through the coordinated movement between the tensioning structure and the fixed structure and the extension adjustment structure and the internal structure of the extension structure, firstly, the overall length of the stretching rod is adjusted over a long distance between the extension shaft rod and the shaft rod body. After adjusting to a suitable distance, one end of the stretching rod is fixedly installed through the cooperation of the shaft rod body and the extension shell body, so that the extension adjustment structure and the fixed structure have the functions of quick installation and locking, which is convenient for the overall stretching and supporting of the stretching rod. Finally, through the internal structure of the tensioning structure, the fixed structure is driven to move in the direction of the tensioning structure, and the two tensioning structures are contracted with each other, so as to achieve the contraction and stretching effect on the stretching rod, so that the structure between the two first supporting structures is more compact and more stable, and multiple first supporting structures can be arranged and connected to strengthen the degree of fixation between each structure, further improve the overall strength of the first supporting structure, make the supporting effect of the beam support more significant and also have the ability to resist the lateral force of the beam support, further expand the scope of use of the device.

DETAILED DESCRIPTION

[0027] 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. Example

[0028] See also Figure 1-7 A ring beam replacement and reinforcement structure for a concrete structure building includes a building beam 1 and a first supporting structure 2 in the building beam 1. The first supporting structure 2 includes a supporting shell 21, a right-angle supporting frame 22, a hollow groove 23, a casting groove 24 and a reinforcing steel bar 25. The supporting shell 21 is used to be installed on one side of the inner wall of the building beam 1. The right-angle supporting frame 22 is installed inside the supporting shell 21. The hollow groove 23 is provided on one side of the right-angle supporting frame 22. The inner wall of the building beam 1 is also provided with a casting groove 24. The casting groove 24 is installed with a reinforcing steel bar 25. One end of the reinforcing steel bar 25 is used to be embedded in the hollow groove 23. One side of the right-angle supporting frame 22 is used to be embedded in the casting groove 24. The interior of the supporting shell 21 is filled with concrete.

[0029] One side of the right-angle support frame 22 is embedded in the casting groove 24, and one end of the reinforcing steel bar 25 is stuck in the inside of the hollow groove 23. Then, the support shell 21 is buckled on the outer surface of the inner wall of the building beam 1, and one end of the support shell 21 is stuck between the two sides of the right-angle support frame 22 and the inner wall of the casting groove 24, so that the right-angle support frame 22 is located inside the support shell 21. At this time, concrete is filled into the support shell 21;

[0030] When the concrete is shaped, it will form a bonding effect on the right-angle support frame 22 and the reinforcing steel bar 25 according to the shape of the inside of the support shell 21, and at the same time strengthen the fixation between the two. By coordinating the internal structure of the building beam 1 and the first support structure 2, and changing the connection method between one side of the right-angle support frame 22 and the inner wall of the building beam 1, the bite degree between the two is increased;

[0031] The transverse plug-in combination of the reinforcing steel bar 25 and the hollow groove 23 can further provide vertical load pressure for the right-angle support frame 22, and the upper end of the right-angle support frame 22 is in contact with the inner wall of the building beam 1, providing support for the building beam 1. The interior of the building beam 1 is also filled with concrete. When the right-angle support frame 22 is located inside the casting trough 24, it plays a role in fixing the stability between the two and increasing the connectivity between the beam body and the device, making the overall device more coherent. At the same time, the connection strength between the right-angle support frame 22 and the inner wall of the building beam 1 is strengthened, so that the pressure on the side of the building beam 1 is effectively transmitted to the lower end of the building beam 1. In addition, compared with the previous split structure, the device has a tighter connection and a greater bearing capacity, so that the device can adapt to the transmission of large weights and support effects. Example

[0032] This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-7 A second supporting structure 3 is provided on one side of the supporting shell 21, and the second supporting structure 3 includes a supporting bracket 31, an inner bracket 32, an outer bracket 33, a toggle pin 34, a first supporting shaft 35 and a second supporting shaft 36. A supporting bracket 31 is provided on one side of the supporting shell 21, and the inner bracket 32 ​​is installed inside the supporting bracket 31, and the outer bracket 33 is installed at the lower end of the inner bracket 32. A toggle pin 34 is provided at one end of the outer bracket 33, and the first supporting shaft 35 is installed inside the inner bracket 32, and the second supporting shaft 36 is installed inside the outer bracket 33. The first supporting shaft 35 is used to rotatably connect the inner bracket 32 ​​to the supporting bracket 31, and the second supporting shaft 36 is used to rotatably install the outer bracket 33 in the supporting bracket 31. The height of the upper end of the outer bracket 33 is higher than the height of one side of the inner bracket 32. The angle of the inner side of the right-angle supporting bracket 22 is ninety-five degrees, and the right-angle supporting bracket 22 includes a supporting cross beam and a supporting vertical beam.

[0033] Generally, when loading a beam, the longer the beam extends outward, the more weight it needs to support, and the edges of the beam require a larger support structure for support;

[0034] The upper end of the right-angle support frame 22 is attached to the inner wall of the building beam 1, and the upper surface of the outer bracket 33 is attached to the lower surface of one end of the supporting beam. At this time, the push pin 34 is attached to the lower end of the inner bracket 32, and provides support and limit effect for the whole inner bracket 32, and supports the inner position of the supporting beam;

[0035] The outer bracket 33 is higher than the inner bracket 32 ​​in support height and the supporting crossbeam is tilted upward, so that the support force at the edge of one side of the building beam 1 is greater than the inner area of ​​the building beam 1, and the edge of the building beam 1 is strengthened to support the edge. When the edge of the building beam 1 bears downward pressure, the inner bracket 32 ​​and the outer bracket 33 are provided with a lever effect through the first support shaft 35 and the second support shaft 36, so that the downward pressure of the building beam 1 is transmitted to the upper end of the outer bracket 33, and the outer bracket 33 is tilted and transmitted to the toggle pin 34, and then the toggle pin 34 pushes the lower end of the inner bracket 32 ​​to one side, and the inner bracket 32 ​​is a nearly right-angle structure.

[0036] When it is pushed open, the upper end of the inner bracket 32 ​​is lifted up and acts on the inner position of the supporting beam, and the inner position of the upper end of the supporting beam is pushed up, and the building beam 1 is lifted up at the same time. The building beam 1 is a right-angle structure, and when the inner side is subjected to the lifting force, its edge position will be lifted up, thereby forming a linkage inside the device of the building beam 1, and the downward pressure on the edge of the building beam 1 is converted into a lifting force on the inner side of the building beam 1 by the outer bracket 33 and the inner bracket 32, and an upward lifting force is provided for the lower end of one side of the building beam 1, thereby achieving a supporting effect on the edge position of one side of the building beam 1. Example

[0037] This embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figure 1-7 A tensioning structure 4 is provided on both sides of the first supporting structure 2, a fixed structure 5 is installed at one end of the tensioning structure 4, a stretching rod 9 is installed at one end of the fixed structure 5, the stretching rod 9 includes an extension adjustment structure 6, an extension structure 7 and a connecting steel bar 8, extension structures 7 are installed at both ends of the connecting steel bar 8, an extension structure 6 is installed at one end of the extension structure 7, and one end of the extension adjustment structure 6 is used to be installed in the fixed structure 5.

[0038] By cooperating with the stretching rod 9, the tensioning structure 4 and the fixing structure 5, the two first supporting structures 2 can be connected to each other, which can increase the lateral stability of the beam support and enable the device to have a lateral load-bearing function, thereby enabling the device to have a multiple weight support function. If the building is connected in a ring shape, multiple first supporting structures 2 can also be connected by the stretching rod 9, and the entire building can be folded at the same time. Example

[0039] This embodiment is an improvement made on the basis of embodiment 3. For details, please refer to Figure 1-7 The tensioning structure 4 includes an outer shell 41, an inner cavity 42, a driving wheel 43 and a supporting threaded shaft 44. The inner shell 41 is provided with an inner cavity 42, the driving wheel 43 is installed inside the inner cavity 42, and a supporting threaded shaft 44 is also installed inside the inner cavity 42. The supporting threaded shaft 44 is used to be spirally installed inside the driving wheel 43, and one end of the supporting threaded shaft 44 is used to be fixed to the fixing structure 5.

[0040] The stretching rod 9 needs to be tightened and fixed between the two first supporting structures 2. If the tension of the stretching rod 9 is insufficient, the stability between the two first supporting structures 2 will be affected.

[0041] By rotating the support threaded shaft 44, the support threaded shaft 44 and the inside of the driving wheel 43 are formed into a threaded engagement connection state. While engaging, the support threaded shaft 44 is driven to extend toward the inside of the outer shell 41. Through the connection with the fixed structure 5 and the stretching rod 9, the stretching rod 9 is stretched, and the traction and tightening effect is achieved between the two first support structures 2, and the stability between the two first support structures 2 is greatly increased. In addition, multiple first support structures 2 are fixed to each other, which has a higher degree of stability. Example

[0042] This embodiment is an improvement made on the basis of embodiment 4. For details, please refer to Figure 1-7 Support bearings 46 are installed on both sides of the driving wheel 43, and the support bearings 46 are used to install the driving wheel 43 in the inner cavity 42. The outer side of the driving wheel 43 is provided with oblique external teeth 45, and the outer side of the outer shell 41 is installed with a driving shaft 47. One end of the driving shaft 47 is provided with matching oblique teeth 49, and the matching oblique teeth 49 are used to form a tooth-groove meshing connection with the oblique external teeth 45. A limiting slide 40 is provided at one end of the supporting threaded shaft 44, and a limiting slide bar 48 is provided on the inner wall of the inner cavity 42. The limiting slide bar 48 is connected to the limiting slide bar 40 by a slide groove.

[0043] By rotating the driving shaft 47, the matching oblique teeth 49 and the oblique external teeth 45 form a tooth-groove transmission state, and drive the driving wheel 43 to rotate. While the driving wheel 43 rotates, it forms a threaded engagement state with the outer surface of the supporting threaded shaft 44, and drives the supporting threaded shaft 44 to extend into the outer shell 41. At the same time, the limiting slide bar 48 and the limiting slide plate 40 are connected by a slide groove, providing a limiting support effect for the supporting threaded shaft 44. This structure adopts a mechanical transmission method to adjust the supporting threaded shaft 44, reduce the operating intensity of the operator, and increase the traction force of the supporting threaded shaft 44. Example

[0044] This embodiment is an improvement made on the basis of embodiment 5. For details, please refer to Figure 1-7 The fixed structure 5 includes an extension shell 51, a spring piece 56 and a movable lever 55. One end of the extension shell 51 is connected to one end of the supporting threaded shaft 44. The movable lever 55 is installed inside the extension shell 51. The lower end of the movable lever 55 is installed with a spring piece 56. The inner side of the movable lever 55 is provided with a supporting shaft. The interior of the extension adjustment structure 6 also includes a shaft body 61, a plug-in fixed end 62 and a fixed ring groove 63. One end of the shaft body 61 is provided with a plug-in fixed end 62, and the outer side of the plug-in fixed end 62 is provided with a fixed ring groove 63. One end of the movable lever 55 is used to be stuck in the fixed ring groove 63.

[0045] A fixing structure is required between the fixing structure 5 and the extension adjustment structure 6 to facilitate the operator to fix the integral stretching rod 9 when installing it;

[0046] By inserting the shaft body 61 into the interior of the extension shell 51, when one end of the movable lever 55 is not inside the inner side of the fixed ring groove 63, it will press against the inner wall of the fixed ring groove 63, providing a locking function for the shaft body 61, so that the extension adjustment structure 6 can be quickly installed when connected with the fixed structure 5, and it is convenient for the overall support operation. Example

[0047] This embodiment is an improvement made on the basis of embodiment 6. For details, please refer to Figure 1-7 A sliding sleeve 52 is installed on the outer side of the extension shell 51, a spring 53 is installed on one end of the sliding sleeve 52, and a downward pressing block 54 is provided on the inner wall of the sliding sleeve 52. The lower surface of the downward pressing block 54 is in contact with one end of the movable lever 55.

[0048] By pushing the sliding sleeve 52 to one side, when the sliding sleeve 52 moves, the upper end of the movable lever 55 will directly contact the lower surface of the downward pressing inclined block 54. Through the inclined structure of the lower surface of the downward pressing inclined block 54, when the downward pressing inclined block 54 moves, the upper end of the movable lever 55 is pressed downward. A supporting shaft is provided inside the movable lever 55, and the movable lever 55 is in a lever state through the supporting shaft. At the same time, the lower end of the movable lever 55 is tilted, so that the lower end of the movable lever 55 is withdrawn from the interior of the fixed ring groove 63, so that the shaft rod body 61 and the extension shell 51 are in direct contact and locked state, so that the fixed structure 5 and the extension adjustment structure 6 can realize the functions of convenient fixation and flexible installation. Example

[0049] This embodiment is an improvement made on the basis of embodiment 7. For details, please refer to Figure 1-7 The other end of the shaft body 61 is provided with an inner limit annular groove 65, and the interior of the inner limit annular groove 65 is provided with a threaded groove 66. The extension structure 7 also includes an extension shaft 71, a matching spiral groove 72 and a positioning tooth groove 73. The outer surface of the extension shaft 71 is provided with a matching spiral groove 72, and the matching spiral groove 72 is used to spirally install the extension shaft 71 in the inner limit annular groove 65.

[0050] If the length of the stretching rod 9 is long, when the tensioning structure 4 is tightened as a whole, it is difficult to retract the stretching rod 9 over a long distance, so that the distance between the stretching rods 9 is too large, and it is difficult to achieve the supporting effect of the two first supporting structures 2;

[0051] When one end of the extension shaft 71 is inserted into the shaft body 61, the cooperating spiral groove 72 will rotate along the spiral trajectory of the inner limit annular groove 65. When rotating, the extension shaft 71 will extend toward the inside of the shaft body 61. When the extension shaft 71 is extended toward the inside of the shaft body 61, the distance between the extension adjustment structure 6 and the extension structure 7 can be shortened, thereby changing the overall length of the stretching rod 9, and vice versa. Through this structure, the long-distance adjustment function between the extension adjustment structure 6 and the extension structure 7 can be realized. Example

[0052] This embodiment is an improvement made on the basis of embodiment 8. For details, please refer to Figure 1-7 A rotating outer ring 64 is also installed at one end of the shaft body 61, and a lever wedge block 67 is installed at one end of the rotating outer ring 64. A middle shaft pin 68 is installed on the inner side of the lever wedge block 67, and a connecting shaft pin 69 is installed at one end of the lever wedge block 67. The connecting shaft pin 69 is used to connect one end of the lever wedge block 67 with the rotating outer ring 64. A positioning tooth groove 73 is also provided on the outer side of the extended shaft 71, and one end of the lever wedge block 67 is used to be stuck in the positioning tooth groove 73.

[0053] When the extension shaft 71 is extended to a suitable length, the rotating outer ring 64 is rotated, and one end of the lever wedge 67 is driven to move in conjunction, and the middle shaft pin 68 divides the lever wedge 67 into two ends. Through the traction of one end of the lever wedge 67, the other end is driven to move in the opposite direction, and the lever wedge 67 is arranged in a circular array in the rotating outer ring 64 and is in an inwardly retracted state, so that one end of the lever wedge 67 is stuck in the positioning tooth groove 73, and the positioning tooth groove 73 is fixed, thereby realizing the adaptive adjustment function of the length between the extension adjustment structure 6 and the extension structure 7, and at the same time, the device has a length locking function;

[0054] Through the coordinated movement between the tensioning structure 4 and the fixed structure 5 and the extension adjustment structure 6 and the internal structure of the extension structure 7, the overall length of the stretching rod 9 is first adjusted over a long distance between the extension shaft 71 and the shaft body 61. After adjusting to a suitable distance, one end of the stretching rod 9 is fixedly installed through the coordination between the shaft body 61 and the extension shell 51, so that the extension adjustment structure 6 and the fixed structure 5 have the functions of quick installation and locking, which is convenient for the overall stretching and supporting function of the stretching rod 9;

[0055] Finally, the internal structure of the tensioning structure 4 is used to drive the fixed structure 5 to move toward the tensioning structure 4, and the two tensioning structures 4 are contracted with each other, so as to achieve the contraction and stretching effect on the stretching rod 9, so that the structure between the two first supporting structures 2 is more compact and more stable, and multiple first supporting structures 2 can be arranged and connected to strengthen the degree of fixation between each structure, further improve the overall strength of the first supporting structure 2, make the supporting effect of the beam support more significant, and also have the ability to resist the lateral force of the beam support, further expand the scope of use of the device. Example

[0056] This embodiment is an explanation based on the embodiment 9. For details, please refer to Figure 1-7 A plurality of thin steel bars are arranged inside the connecting steel bar 8, and the connecting steel bar 8 is formed by twisting the thin steel bars.

[0057] Through the function of connecting the steel bars 8, the thin steel bars have certain bending functions, so that the stretch rod 9 as a whole can make adaptive adjustments through the connecting steel bars 8 when dealing with some bending environments.
