Description

Technical Field

[0001] The invention relates to the technical field of concrete frame structures, in particular to an assembled concrete frame structure. Background Art

[0002] Prefabricated concrete structures are energy-saving and environmentally friendly, with fast construction speed, and can greatly improve the quality of concrete pouring, vibration and maintenance. They have become one of the structural forms that conform to the modernization and transformation of my country's construction industry and are being used more and more widely. Generally, most frames are cast on site. In order to speed up the progress of the project and save formwork and top support, partial prefabrication (such as columns) and partial cast-in-place (beams) or cast-in-place joints of prefabricated columns and beams can also be adopted. Existing concrete frame structures include fixed and prefabricated types. As the name implies, the fixed type is directly cast on the concrete frame node, and the crossbeams and longitudinal beams are cast. The main cost is relatively low and meets the construction indicators, but the seismic absorption capacity is poor. Generally, during construction, construction units prefer prefabricated types because they are simple to splice, easy to operate, and easy to transport. The strength is also guaranteed. These prefabricated frame structures are generally divided into fixed and split types. The fixed crossbeams and longitudinal beams are more often connected by bolts and welding. The crossbeams and longitudinal beams maintain a certain angle, while the split type generally has the function of seismic resistance, absorbing energy, and preventing the wall from being severely split; In the patent technology with Chinese patent authorization number CN112726816B, the technology used is the anti-seismic reset function of the frame structure. This technology is fixed by connecting the ground and the support column through the column foot node structure. The crossbeam and the longitudinal beam are connected by the disc spring group at the beam end. According to the technology, the disc spring group at the beam end can absorb the energy of vibration and then reset itself. The same is true for the column foot node structure. Although the structure absorbs energy through the spring to generate compression, for example, the beam end disc spring group in this technology is connected by stiffening ribs passing through the longitudinal beam, and then the spring is reset to reset the whole, but by Since the vibration direction is not unique, and the source of force generated is not the same, the structure can absorb lateral force by separating the end plate and the longitudinal beam, and then driving the end plate to reset after the spring is compressed. For this structure, the longitudinal force will produce shear stress between the stiffening rib and the longitudinal beam. One of the stiffening rib and the longitudinal beam will inevitably be damaged, and the position of the longitudinal beam and the cross beam will change, causing the entire frame to deform and be difficult to repair. In addition, the spring is exposed outside, which is prone to corrosion and failure over time. Therefore, this structure also has certain defects. For this reason, we propose an assembled concrete frame structure. Summary of the invention

DETAILED DESCRIPTION

[0016] 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.

[0017] See also Figure 1-10The present invention provides a technical solution: an assembled concrete frame structure, comprising a plurality of connection seats 1 fixed on the ground, each of which is interspersed with a main support column 2 on the top of each connection seat 1, a sleeve frame 3 is detachably connected to the top of the main support column 2, and a U-shaped steel groove 7 is fixedly connected to the sleeve frame 3 on all sides, and each of the U-shaped steel grooves 7 is slidably connected to any one of a first-stage column 6a, a second-stage column 6b, and a third-stage column 6c, and the three-stage column 6c is respectively close to the ends of the second-stage column 6b and the first-stage column 6a, and two groups of three-stage columns 6c, two groups of one-stage columns 6a, and two groups of two-stage columns 6b are combined to form a rectangular Structure, each of the sleeve frames 3 is equipped with a sealing seat 4 on the top, and a connecting cover 5 is detachably installed on the top of the sealing seat 4. A connecting rod 9 is fixedly connected between each corner of the sealing seat 4 and the main support column 2, and a positioning pin 8 is connected between the connecting cover 5 and the connecting rod 9. A supporting column 11 is suspended on the top of the connecting cover 5, and a first spring 12 is sleeved on the outside of the supporting column 11. A pressure plate 13 is fixedly connected to the bottom of the first spring 12, and the pressure plate 13 is in conflict with the ends of the first column 6a, the second column 6b and the third column 6c located inside the sleeve frame 3. First, when installing, the longitudinal direction on the ground is used to connect the main support column 2. As the foundation, multiple connecting seats 1 are installed in sequence from the bottom to the top, and the main support column 2 is installed on each connecting seat 1. Then, each sleeve frame 3 is placed on the top of each main support column 2, and then the connecting rod 9 is fixed by bolts at the corners of the main support column 2 manually, and then the sealing seat 4 is placed on the top of the sleeve frame 3 to compact the sleeve frame 3, and finally the connecting cover 5 is placed on the top of the sealing seat 4, and then the positioning pin 8 is inserted between the connecting rod 9 and the connecting cover 5, wherein the bottom of the positioning pin 8 extends through the sealing seat 4, and then the connecting rod 9 is fixed by the positioning pin 8 on the top of the connecting cover 5, and the sleeve frame 3 and The sealing seat 4 and the connecting cover 5 are locked; then, a crane is used to transfer a first-stage column 6a or a second-stage column 6b to the U-shaped steel groove 7 on the sleeve frame 3 of the first batch of longitudinal columns, and the end of the second-stage column 6b is placed on the U-shaped steel groove 7. After the crane is removed, the second-stage column 6b is suspended on the sleeve frame 3 using the edge of the sleeve frame 3 as a lever, and then the positions of the multiple connecting seats 1 of the first batch of longitudinal columns are determined again. By analogy, the positions of the sleeve frames 3 of each installation batch in the horizontal and vertical columns can be determined in this way, which greatly saves the measurement time. When all the connecting seats 1 and the first-stage column 6a, the second-stage column 6b and the third-stage column 6c are installed, as shown in the attached figure Figure 1As shown, the end of each first-stage column 6a, second-stage column 6b and third-stage column 6c extends into the interior of the sleeve 3, and the pressure plate 13 at the bottom of the first spring 12 presses the U-shaped steel groove 7 and each column to ensure the stability of the overall structure. The first spring 12 is located inside the sleeve 3 and is not prone to natural damage such as rust. When the overall frame is vibrated, each first-stage column 6a, second-stage column 6b and third-stage column 6c bounces on the entire structure. Therefore, the first spring 12 increases the energy absorption effect each time it bounces, preventing the ends of the first-stage column 6a, second-stage column 6b and third-stage column 6c from being damaged during the vibration, thereby improving the service life of the overall structure.

[0018] Furthermore, the first-stage column 6a, the second-stage column 6b and the third-stage column 6c are all made of concrete, and the first-stage column 6a, the second-stage column 6b and the third-stage column 6c are all at the same height from the ground through the U-shaped steel groove 7. During the manufacturing process, steel bars are installed inside the first-stage column 6a, the second-stage column 6b and the third-stage column 6c, and beams are formed by inverted molds of templates. During installation, a crane is used to transport each first-stage column 6a, the second-stage column 6b and the third-stage column 6c to the U-shaped steel groove 7 around the frame 3 for splicing. Among them, it is worth mentioning that the first-stage column 6a, the second-stage column 6b and the third-stage column 6c are of the same specification, but the length of each is customized according to actual needs, so each column can be classified and produced, and the actual needs in reality are implemented according to the floor space occupied by each connecting seat 1, so it is necessary to determine the distance between each connecting seat 1.

[0019] Furthermore, each of the first-stage column 6a, the second-stage column 6b and the third-stage column 6c has a beam end groove 601 at the top of both ends, and each of the first-stage column 6a, the second-stage column 6b and the third-stage column 6c has a clamping groove 602 at the bottom of both ends. Each side of the sleeve frame 3 extends downward to form a redundant area, and the redundant area is connected to the U-shaped steel groove 7. Each redundant area corresponds to each beam end groove 601. The clamping groove 602 and the U-shaped steel groove 7 are connected together with a flat key. When the connecting seat 1 on one or one area vibrates, the first-stage column 6a, the second-stage column 6 b and one of the three-section column 6c will generate a lever through the slot 602 and the U-shaped steel groove 7, and the crossbeam end slot 601 at one end of the one-section column 6a, the two-section column 6b and the three-section column 6c will move to the redundant area, and at the same time, the other end will have a downward pressure trend. Since the slot 602 and the U-shaped steel groove 7 are spliced ​​with each other, the one-section column 6a, the two-section column 6b and the three-section column 6c of each section can be firmly buckled with the sleeve frame 3 under the restraint of the slot 602 and the U-shaped steel groove 7, preventing the one-section column 6a, the two-section column 6b and the three-section column 6c from derailing when encountering vibration.

[0020] Furthermore, the ends of the first-stage column 6a, the second-stage column 6b and the third-stage column 6c are all wedge-shaped, and a fixed base 15 is fixedly installed at the bottom of each of the sleeve frames 3. The middle part of the fixed base 15 is arched upward to form an arched platform, and a pin block 16 is fixedly installed on the top of the arched platform in the middle of the fixed base 15. The pin block 16 has an active cavity opened inside toward the end of each first-stage column 6a, the second-stage column 6b and the third-stage column 6c. The ends of the first-stage column 6a, the second-stage column 6b and the third-stage column 6c are all fixedly installed with an active cavity. The movable ball 603 is connected with the movable cavity pin; the top of the pin block 16 is fixedly installed with baffles 1601 all around, the bottom of the pressure plate 13 is fixedly installed with a rotating angle steel holder 14, and the rotating angle steel holder 14 is provided with a plurality of clamping areas 1401. The pin block 16 is fixedly connected with the rotating angle steel holder 14 after docking with the baffle 1601 and the clamping area 1401, and the top of the pressure plate 13 is slidably connected with a plurality of limit rods 10, and the plurality of limit rods 10 are fixed on the connection cover 5. When the vibration source When the direction is not unique and is relatively large, the first column 6a, the second column 6b and the third column 6c may rotate on the sleeve frame 3 with the main support column 2 as the rotation axis, which will make it impossible for any of the first column 6a, the second column 6b and the third column 6c to be reset after displacement. Therefore, when the entire structure is vibrated, the first column 6a, the second column 6b and the third column 6c rotate until they contact each connecting rod 9. When the sleeve frame 3 rotates, the first column 6a, the second column 6b and the third column 6c rotate until they contact each connecting rod 9. The ends of the first column 6b and the third column 6c drive the movable ball 603 to move laterally to the initial position, causing the pin block 16 to rotate. When the pin block 16 rotates, the baffle 1601 can drive the angle steel holder 14 to rise linearly in the positioning area 1401, further causing the first spring 12 to be stressed. After the first spring 12 is stressed, the pressure plate 13 is driven down in an energy-absorbing manner, allowing the first column 6a, the second column 6b and the third column 6c to generate reverse driving force, thereby improving the seismic resistance of the device.

[0021] Furthermore, the connecting seat 1 includes a buried plate 102 arranged on the ground, the corners of the buried plate 102 are fixedly connected with anti-seismic strips, a docking template 105 is fixedly connected at the bottom between the multiple anti-seismic strips, and a mounting plate 103 is detachably connected between two adjacent anti-seismic strips, and the multiple mounting plates 103 surround the main support column 2 on the side and each mounting plate 103 is fixedly connected with a shock absorbing damper 104 on this side, and each shock absorbing damper 104 conflicts with the main support column 2, and a mounting plate 103 is arranged between the buried plate 102 and the docking template 105. There is a sealing area 101, in which when installing the connecting seat 1, the buried plate 102 is sealed underground and then buried with soil, and then mud is poured in the sealing area 101. After the mud dries, it provides downward pressure for the overall support and improves the stability of the overall frame. When vibration occurs, the shock-absorbing damper 104 absorbs the vibration of the main support column 2 to stabilize the main support column 2. In addition, the bottom of the main support column 2 and the docking template 105 are fixedly connected with reinforced concrete, so that the main support column 2 and the docking template 105 will not loosen during the vibration.

[0022] Furthermore, a plurality of blocking areas 18 are fixedly installed inside each of the movable cavities, each of the blocking areas 18 is arranged toward the inner wall of the sleeve frame 3, and each of the blocking areas 18 is in conflict with the movable ball 603, and a plurality of reinforcing ribs 604 are fixedly installed outside each of the movable balls 603, and one end of each of the reinforcing ribs 604 is fixedly connected to the ends of the first-section column 6a, the second-section column 6b and the third-section column 6c, and a second spring 17 is fixedly connected between the pin block 16 and the reinforcing rib 604. During installation, a damping pad is fixedly filled into the blocking area 18, which can effectively absorb shock and reduce noise during slight vibrations. The second spring 17 can effectively make the damping pad inside the pin block 16 contact with the movable ball 603, and the reinforcing rib 604 prevents the ends of the first-section column 6a, the second-section column 6b and the third-section column 6c from breaking.

[0023] Furthermore, at least one movable ball 603 is provided, and each movable ball 603 is fixedly connected to the inner steel bars of the first column 6a, the second column 6b and the third column 6c. The middle part of the fixed base 15 is fixedly connected to the inner steel bars of the main support column 2. The number of movable balls 603 is set according to the usage scenario. If it is used in high-rise buildings or mountainous earthquake zones, the number of movable balls 603 needs to be increased to prevent the movable balls 603 from breaking during vibration.

[0024] Furthermore, connecting plates 19 are fixedly installed between the opposite bottom surfaces of two adjacent connecting seats 1, and a driving rod 20 is fixedly installed on each connecting plate 19. A limiting ball 21 is connected between the two driving rods 20, and a positioning plate 22 is fixedly connected to the bottom of the limiting ball 21. The middle part of the positioning plate 22 extends upward and penetrates into the limiting ball 21, and the top of the middle part of the positioning plate 22 is rotatably connected to a rotating seat 25. A calibration drum 23 is suspended on the top of the limiting ball 21, and a screw 26 is slidably connected to the top of the rotating seat 25. The calibration drum 23 and the screw 26 are threaded together, and a gear 24 is fixedly connected to the outer ring of the calibration drum 23. The gear 24 and a pair of driving rods 20 are meshed together, and the calibration drum 23 and the rotating seat 25 are rotatably connected. First, the limiting ball 21 does not exceed the top of the sealing area 101, and is buried underground with the bottom of the connecting seat 1, as shown in the attached Fig.10 As shown, a connecting piece 19 should be installed on each surface of the bottom of the connecting seat 1 (all surfaces in the figure are not drawn). When the connecting seat 1 vibrates, two or more connecting seats 1 can also pull each other to prevent the connecting seat 1 from vibrating and dislocating. When one of the connecting seats 1 is offset, the offset connecting seat 1 pulls the driving rod 20 connected to it to move. When the driving rod 20 moves, it drives the gear 24 to rotate. The rotation of the gear 24 causes the calibration drum 23 to rotate on the rotating seat 25, so that the screw 26 rises linearly and breaks the ground. The height of the rise of the screw 26 is convenient for manual detection to determine where the offset of the two adjacent connecting seats 1 occurs, and then the two connecting seats 1 are reset using existing means. The existing means can be a right-angle measurement method to measure the angle between the connecting seat 1 and the ground, and then one of the connecting seats 1 can be reset using a ceiling machine, which assists manual observation and improves the convenience and speed of resetting the device.
