Description

Technical Field

[0001] The present 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 conforms to the modernization and transformation of my country's construction industry and are being used more and more widely. Generally, the frames are mostly cast on site. In order to speed up the project progress and save formwork and top support, some parts can be prefabricated (such as columns) and some can be cast in place (beams), or the prefabricated column-beam joints can be cast in place.

[0003] Existing concrete frame structures include fixed and prefabricated types. As the name suggests, the fixed type is directly cast on the concrete frame nodes, 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 tend to choose prefabricated types because they are simple to splice, easy to operate, easy to transport, and have guaranteed strength. These prefabricated frame structures are generally divided into fixed and split types. The fixed crossbeams and longitudinal beams are mostly connected by bolts and welding. The crossbeams and longitudinal beams maintain a certain angle, while the split type generally has seismic resistance, absorbs energy, and prevents the wall from being severely split.

[0004] In the patented technology with the 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 column foot node structure between the ground and the support column, and the crossbeam and the longitudinal beam are connected by the beam end disc spring group. According to the technology, the beam end disc spring group can absorb the energy of vibration and then reset itself. The column foot node structure is the same. 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 a stiffening rib passing through the longitudinal beam, and then the spring is used to reset the whole, but it is reset by Since the vibration direction is not unique, the source of the force generated is not the same. The structure can absorb the 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 generate shear stress between the stiffener and the longitudinal beam. One of the stiffener and the longitudinal beam will inevitably be damaged, and the position of the longitudinal beam and the cross beam will change, causing the deformation of the entire frame to be difficult to repair. In addition, the spring is exposed and prone to corrosion, leading to 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

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-10The present invention provides a technical solution: an assembled concrete frame structure, comprising a plurality of connecting seats 1 fixed on the ground, each of which is interspersed with a main support column 2 installed on the top of each connecting seat 1, a sleeve frame 3 is detachably connected to the top of the main support column 2, and a U-shaped steel channel 7 is fixedly connected to each of the sleeve frames 3 on all sides, and a crossbeam is slidably connected to each of the U-shaped steel channels 7 (in this solution, 6a, 6b and 6c are all crossbeams, which can serve as the main supporting part), the ends of each crossbeam are close to each other, and a sealing seat 4 is installed on the top of each sleeve frame 3. , the top of the sealing seat 4 can be detachably installed with a connecting cover 5, each corner of the sealing seat 4 is fixedly connected to the main support column 2 with a connecting rod 9, a positioning pin 8 is connected between the connecting cover 5 and the connecting rod 9, and the top of the connecting cover 5 is suspended with a supporting column 11, the outside of the supporting column 11 is sleeved with a first spring 12, and the bottom of the first spring 12 is fixedly connected with a pressure plate 13, and the pressure plate 13 is in conflict with the end of the beam inside the sleeve frame 3. First, when installing, take the vertical column on the ground as the basis and install multiple connecting rods from the bottom to the top in sequence. Connect the seat 1, install the main support column 2 on each connecting seat 1, and then place each sleeve frame 3 on the top of each main support column 2, and then manually fix the connecting rod 9 with bolts at the corners of the main support column 2, and then put the sealing seat 4 on the top of the sleeve frame 3 to compact the sleeve frame 3, and finally put the connecting cover 5 on the top of the sealing seat 4, and then insert the positioning pin 8 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 on the top of the connecting cover 5, use the positioning pin 8 to fix the connecting rod 9 by bolting, and put the sleeve frame 3 and the sealing seat 4 on top. Then, use a crane to transport one section column 6a or two sections column 6b to the U-shaped steel channel 7 on the sleeve frame 3 of the first batch of longitudinal columns, and place the end of the two sections column 6b on the U-shaped steel channel 7. After removing the crane, the two sections column 6b is hung on the sleeve frame 3 with 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 can be determined again. By analogy, the positions of the sleeve frames 3 of each installation batch of transverse columns and longitudinal columns can be determined in this way, which greatly saves measurement time. When all the connecting seats 1 and beams are installed, as shown in the attached figure, Figure 1 As shown, the end of each beam 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 channel 7 and each column to ensure the stability of the overall structure. The first spring 12 is located inside the sleeve 3 and is difficult to cause natural damage such as rust. When the entire frame is vibrated, each beam bounces on the entire structure. Therefore, the first spring 12 increases the energy absorption effect every time it bounces, preventing the end of the beam from being damaged during the vibration process, thereby improving the service life of the overall structure.

[0028] Furthermore, the crossbeams are made of concrete, and each crossbeam passes through a U-shaped steel trough and has the same height from the ground. During the manufacturing process, steel bars are installed inside the crossbeams, and the beams are formed by inverting the formwork. During installation, each crossbeam is transported by a crane to the U-shaped steel trough 7 around the frame 3 for splicing. It is worth mentioning that the crossbeams are of the same specifications, but the length of each is customized according to actual needs, so each column can be classified and produced. In reality, the actual needs are implemented according to the ground occupation of each connecting seat 1, so it is necessary to determine the distance between each connecting seat 1.

[0029] Furthermore, a beam end groove 601 is provided at the top of each of the two ends of the beam, and a clamping groove 602 is provided at the bottom of each of the two ends of the beam. Each side of the 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, and 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 an area vibrates, one of the beams will generate a lever through the clamping groove 602 and the U-shaped steel groove 7, and the beam end groove 601 at one end of the beam will move toward the redundant area, while the other end will have a downward pressure trend. Since the clamping groove 602 and the U-shaped steel groove 7 are spliced ​​with each other, each section of the beam can be firmly buckled with the frame 3 under the restraint of the clamping groove 602 and the U-shaped steel groove 7, preventing the beam from derailing during vibration.

[0030] Furthermore, both ends of the multiple beams are wedge-shaped, and a fixed base 15 is fixedly installed at the bottom of each sleeve 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. A movable cavity facing each beam end is provided inside the pin block 16, and the beam ends are fixedly installed with movable balls 603, and the movable balls 603 are connected to the movable cavity pins together; baffles 1601 are fixedly installed on the top of the pin block 16, and a rotating angle steel holder 14 is fixedly installed at the bottom of the pressure plate 13, and a plurality of positioning areas 1401 are provided on the rotating angle steel holder 14. The pin block 16 is fixedly connected to the rotating angle steel holder 14 after docking with the baffle 1601 and the positioning area 1401, and a plurality of limit rods 10 are slidably connected to the top of the pressure plate 13, and a plurality of limit rods 10 are all fixed on the connecting cover 5. When the direction of the vibration source is not unique and is relatively large, the beam may rotate on the sleeve frame 3 with the main support column 2 as the rotation axis. This will make it impossible for any beam to be reset after displacement. Therefore, when the overall structure is subjected to vibration, the rotation angle of the beam is until it contacts each connecting rod 9. When the sleeve frame 3 rotates, the end of the beam drives 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 on 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 the same energy-absorbing manner, causing the beam to generate a reverse driving force, thereby improving the seismic performance of the device.

[0031] Furthermore, the connecting seat 1 includes a buried plate 102 set on the ground, and the corners of the buried plate 102 are fixedly connected to the anti-seismic strips, and the bottoms of the multiple anti-seismic strips are fixedly connected to the docking template 105. The mounting plate 103 can be detachably connected between two adjacent anti-seismic strips. The multiple mounting plates 103 surround the main support column 2 on the side and each mounting plate 103 is fixedly connected to a shock absorbing damper 104 on this side. Each of the shock absorbing dampers 104 conflicts with the main support column 2. A space is set 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, thereby improving 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 process.

[0032] 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 and the movable ball 603 are in conflict with each other, 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 end of the beam, 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 end of the beam from breaking.

[0033] Furthermore, at least one movable ball 603 is provided, and each movable ball 603 is fixedly connected to the internal steel bar of the beam, and the middle part of the fixed base 15 is fixedly connected to the internal steel bar of the main support column 2. The number of movable balls 603 is set according to the usage scenario. If it is used in a high-rise building or a mountainous earthquake zone, the number of movable balls 603 needs to be increased to prevent the movable balls 603 from breaking during the vibration process.

[0034] Furthermore, connecting pieces 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 piece 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. 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 the outer ring of the calibration drum 23 is fixedly connected to a gear 24, and the gear 24 and a pair of driving rods 20 are meshed together. 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 the bottom of the connecting seat 1 is buried underground, as shown in the attached Figure 10As 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 drive rod 20 connected to it to move. When the drive 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 straight up and breaks the ground. The height to which the screw 26 rises 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.
