Description

Technical Field

[0001] The present invention relates to the technical field of earthquake-resistant residential structures, and in particular to a high-strength assembled earthquake-resistant residential structure. Background Art

[0002] Prefabricated houses are buildings assembled on site from prefabricated components. In order to improve the construction efficiency and quality of the project, more and more houses with two floors or more are assembled and constructed using prefabricated steel structures and prefabricated concrete structures. The assembled prefabricated steel structures have the advantages of high strength, good integrity, and strong seismic stability.

[0003] After searching, the Chinese patent (publication number: CN113338669B) disclosed "an assembled earthquake-resistant residential building structure, including a civil foundation, on which load-bearing columns and a load-bearing frame are vertically arranged, on which wall panels and floor slabs are installed, and on which roof panels are installed the tops of the load-bearing columns and the load-bearing frames, and the load-bearing columns and the load-bearing frames are interconnected by a suspension mechanism, a shock-absorbing mechanism is arranged between the load-bearing columns and the civil foundation, and a horizontal offset mechanism is arranged between the load-bearing frame and the civil foundation.

The outer side of the lower beam column is provided with a plurality of connecting bolts that are threadedly matched with the first screw holes, and the ends of the plurality of first screw holes are fixedly connected with threaded extension sleeves that are threadedly connected to the connecting bolts.

[0009] Preferably, the docking member also includes a guide rod fixedly connected to the bottom of the docking seat, the bottom of the guide rod is fixedly connected to a first friction block, the inner side of the lower beam is fixedly connected to a fixing plate, and the top of the fixing plate is provided with a buffer member that slides with the first friction block.

[0010] Preferably, the auxiliary part includes two pins, which are rotatably connected to the two ends of the inner side of the first connecting plate respectively, and the two pins are fixedly connected to an inclined pressure plate, and one end of the two pins is sleeved with a torsion spring, one end of the torsion spring is welded to the pressure plate, and the other end of the torsion spring is welded to the inner wall of the first connecting plate.

[0012] Preferably, elastic friction plates are fixedly connected to the four sides of the inner side of the sleeve, and the second friction block and the first friction block are slidably connected to the elastic friction plates.

[0013] Preferably, a positioning mechanism is provided on the inner side of the horizontal beam, and the positioning mechanism includes a screw rod, the screw rod passes through the bottom wall of the horizontal beam and is threadedly connected to the bottom wall of the horizontal beam, the bottom end of the screw rod is fixedly connected to a rotating cap, the top end of the screw rod is rotatably connected to a mounting seat, the top end of the mounting seat is rotatably connected to two coaxially arranged connecting rods, the ends of the two connecting rods away from the mounting seat are hinged with positioning rods, the two positioning rods are respectively slidably connected to the two ends of the inner side of the horizontal beam, and the ends of the two positioning rods away from the corresponding connecting rods are slidably matched with the corresponding lap seats.

[0016] The working principle and beneficial effects of the present invention are: 1.

This makes the upper and lower positions of the docking seat fixed by bolts, so that the upper beam is stably installed on the lower beam, which greatly improves the overall stability; 2. During assembly, you only need to hoist the upper beam to the top of the lower beam, and then lower the upper beam so that the docking seat moves downward and contacts the pressure plate, causing the pressure plate to rotate under force. At this time, the torsion spring contracts to produce a reverse elastic force, causing the two pressure plates to apply pressure to the docking seat at the same time, causing the docking seat to approach the center of the lower beam until the docking seat and the lower beam slide together. This can achieve rapid coordination between the docking seat and the lower beam without repeated manual adjustments, greatly saving assembly time and improving the efficiency of column lap joints in multi-story steel structures. 3. By slidingly fitting the docking seat with the lower beam, the first friction block and the sleeve seat are slidably fitted, so that the first friction block contacts the second friction block. Since the bottom of the second friction block is welded to the buffer spring, the first friction block and the second friction block are in elastic contact. When the overall structure is subjected to severe vibration, the first friction block will exert pressure on the second friction block, so that the buffer spring is compressed to produce a reverse elastic force, which can reduce the impact force on the steel structure. At the same time, sliding friction occurs between the first friction block, the second friction block and the elastic friction plate, so that the impact energy of the steel structure is consumed in the form of heat energy, thereby reducing the vibration of the overall structure. The elastic properties of the elastic friction plate itself can maintain a close fit with the first friction block and the second friction block, thus avoiding the problem of reduced friction efficiency due to wear of the first friction block and the second friction block.

DETAILED DESCRIPTION

[0020] The following will be combined with 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.

[0021] like Figure 1 to Figure 8 As shown, this embodiment proposes a high-strength assembled earthquake-resistant residential structure, including a plurality of lower beams 1 arranged in parallel, upper beams 2 are arranged above the plurality of lower beams 1, and a docking mechanism 3 is arranged between the plurality of upper beams 2 and the corresponding lower beams 1, and the docking mechanism 3 includes a first connecting plate 31, the first connecting plate 31 is fixedly connected to the top of the corresponding lower beam 1, and the bottom of the lower beam 1 is fixedly connected to the second connecting plate 32, the second connecting plate 32 is stacked on the top of the first connecting plate 31, and the second connecting plate 32 and the first connecting plate 31 are fixed by bolts. The first connecting plate 31 and the second connecting plate 32 are both rectangular frame structures, and the cross-sectional areas of the second connecting plate 32 and the first connecting plate 31 are exactly the same. The bottom of the second connecting plate 32 is provided with a docking piece 33 that slides with the lower beam column 1, and the inner side of the first connecting plate 31 is provided with an auxiliary piece 34 for assisting the second connecting plate 32 to cooperate with the lower beam column 1. The outer sides of several lower beam columns 1 are fixedly connected with a lap seat 4, and a horizontal beam 5 is clamped between two adjacent lap seats 4. Both ends of the horizontal beam 5 are fixedly connected with the corresponding lap seat 4 by bolts. The upper beam column 2 realizes the connection of the upper and lower columns by sliding with the lower beam column 1 through the docking piece 33, and during the assembly process, the docking piece 33 can be accurately docked with the lower beam column 1 through the auxiliary piece 34, so as to realize the rapid assembly of the upper and lower columns, which greatly saves the assembly adjustment time and improves the assembly efficiency.

[0022] Furthermore, the docking member 33 includes a docking seat 331, which is slidably matched with the lower beam 1, and a plurality of first screw holes 332 are provided on the side walls around the docking seat 331. The outer side of the lower beam 1 is provided with a plurality of connecting bolts 11 threadedly matched with the first screw holes 332, and the ends of the plurality of first screw holes 332 are fixedly connected with threaded extension sleeves 333 threadedly connected with the connecting bolts 11. The bottom of the docking seat 331 is fixedly connected with a guide rod 334, and the bottom of the guide rod 334 is fixedly connected with a first friction block 335. The inner side of the lower beam 1 is fixedly connected with a fixing plate 35, and the top of the fixing plate 35 is provided with a buffer member 36 slidably matched with the first friction block 335.

[0023] During assembly, the second connecting plate 32 is completely overlapped and tightly fitted with the second connecting plate 32 by sliding the docking seat 331 with the lower beam 1, and then the second connecting plate 32 is fixed to the first connecting plate 31 by high-strength bolts, and then the docking seat 331 is fixed to the lower beam 1 by connecting bolts 11. This makes the upper and lower positions of the docking seat 331 both subject to the action of bolts, so that the upper beam 2 is stably installed on the lower beam 1, greatly improving the overall stability.

[0024] Furthermore, the auxiliary component 34 includes two pin shafts 341, which are rotatably connected to the two ends of the inner side of the first connecting plate 31 respectively, and the two pin shafts 341 are fixedly connected to an inclined pressure plate 342.

[0025] During assembly, it is only necessary to lift the upper beam 2 to the top of the lower beam 1, and then lower the upper beam 2 so that the docking seat 331 moves downward and contacts the pressure plate 342, causing the pressure plate 342 to rotate under force. At this time, the torsion spring 343 contracts to produce a reverse elastic force, causing the two pressure plates 342 to apply pressure to the docking seat 331 at the same time, causing the docking seat 331 to approach the center of the lower beam 1 until the docking seat 331 slides with the lower beam 1. This allows the docking seat 331 to quickly fit with the lower beam 1 without the need for repeated manual adjustments, greatly saving assembly time and improving the efficiency of column lap joints in multi-story steel structures.

[0026] Furthermore, the buffer member 36 includes a sleeve 361 fixedly connected to the top of the fixed plate 35, the sleeve 361 is slidably matched with the first friction block 335, a buffer spring 363 is welded to the bottom end of the inner side of the sleeve 361, and a second friction block 362 is welded to the top end of the buffer spring 363, the second friction block 362 is in contact with the first friction block 335, and elastic friction plates 364 are fixedly connected to the inner side of the sleeve 361 all around, and the second friction block 362 and the first friction block 335 are both slidably connected to the elastic friction plate 364.

[0027] By slidingly matching the docking seat 331 with the lower beam 1, the first friction block 335 and the sleeve seat 361 are slidably matched, so that the first friction block 335 and the second friction block 362 are in conflict. Since the bottom of the second friction block 362 is welded to the buffer spring 363, the first friction block 335 and the second friction block 362 are in elastic contact. When the overall structure is subjected to severe vibration, the first friction block 335 will apply pressure to the second friction block 362, so that the buffer spring 363 is compressed to generate a reverse elastic force, which can reduce the impact force on the steel structure. At the same time, sliding friction occurs between the first friction block 335, the second friction block 362 and the elastic friction plate 364, so that the impact energy of the steel structure is consumed in the form of heat energy, thereby reducing the vibration of the overall structure. The elastic performance of the elastic friction plate 364 itself can maintain a close fit with the first friction block 335 and the second friction block 362, thereby avoiding the problem of reduced friction efficiency due to wear of the first friction block 335 and the second friction block 362.

[0028] Furthermore, a positioning mechanism 6 is provided on the inner side of the horizontal beam 5, and the positioning mechanism 6 includes a screw 61, the screw 61 passes through the bottom wall of the horizontal beam 5 and is threadedly connected to the bottom wall of the horizontal beam 5, the bottom end of the screw 61 is fixedly connected to a rotating cap 62, the top end of the screw 61 is rotatably connected to a mounting seat 63, the top end of the mounting seat 63 is rotatably connected to two coaxially arranged connecting rods 64, the ends of the two connecting rods 64 away from the mounting seat 63 are hinged with positioning rods 65, and the two positioning rods 65 are respectively slidably connected to the water At the two ends of the inner side of the flat beam 5, the two positioning rods 65 are slidably matched with the corresponding lap joint 4 at one end away from the corresponding connecting rod 64, and guide grooves 66 slidably connected to the positioning rods 65 are provided at both ends of the horizontal beam 5. A number of third screw holes 67 are provided on the upper and lower sides of the horizontal beam 5. The cross-section of the lap joint 4 is a U-shaped structure. A positioning groove 42 matching the positioning rod 65 is provided in the middle of the lap joint 4, and a number of second screw holes 41 corresponding to the third screw holes 67 are provided on the upper and lower sides of the lap joint 4.

[0029] Workflow: During assembly, the upper beam 2 is hoisted above the lower beam 1, and then the upper beam 2 is lowered so that the docking seat 331 moves downward and contacts the pressing plate 342, so that the pressing plate 342 is forced to rotate. At this time, the torsion spring 343 contracts to generate a reverse elastic force, so that the two pressing plates 342 simultaneously apply pressure to the docking seat 331, so that the docking seat 331 approaches the center of the lower beam 1, until the docking seat 331 and the lower beam 1 are slidably matched. This can achieve rapid matching between the docking seat 331 and the lower beam 1, without the need for repeated manual adjustments, which greatly saves assembly time. When the docking seat 331 and the lower beam 1 are slidably matched, the second connecting plate 32 and the second connecting plate 32 are completely overlapped and tightly attached, and then the second connecting plate 32 and the first connecting plate 31 are fixed by high-strength bolts, and then the docking seat 331 and the lower beam 1 are fixed by connecting bolts 11, so that the upper and lower positions of the docking seat 331 are fixed by bolts, so that the upper beam 2 is stably installed on the lower beam 1, which greatly improves the overall stability; During the sliding cooperation between the docking seat 331 and the lower beam 1, the first friction block 335 will slide with the sleeve seat 361, so that the first friction block 335 and the second friction block 362 are in conflict. Since the bottom of the second friction block 362 is welded to the buffer spring 363, the first friction block 335 and the second friction block 362 are in elastic contact. When the overall structure is subjected to severe vibration, the first friction block 335 will apply pressure to the second friction block 362, so that the buffer spring 363 is compressed to generate a reverse elastic force, which can reduce the impact force on the steel structure. At the same time, sliding friction occurs between the first friction block 335, the second friction block 362 and the elastic friction plate 364, so that the impact energy on the steel structure is consumed in the form of heat energy, thereby reducing the vibration of the overall structure. The elastic performance of the elastic friction plate 364 itself can maintain a close fit with the first friction block 335 and the second friction block 362, thus avoiding the problem of reduced friction efficiency caused by wear of the first friction block 335 and the second friction block 362. By respectively clamping the two ends of the horizontal beam 5 on the two lap seats 4, and then fixing the horizontal beam 5 and the lap seat 4 with high-strength bolts, and then rotating the rotating cap 62 to rotate the screw 61, the screw 61 drives the mounting seat 63 to move upward, so that the two connecting rods 64 rotate and the angle between the two connecting rods 64 becomes larger, which makes the two positioning rods 65 slide back to back and cooperate with the positioning grooves 42 of the corresponding lap seat 4, which can further improve the stability of the horizontal beam 5 and the lap seat 4.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
