Description

Technical Field

[0001] The utility model belongs to the field of prefabricated buildings, and in particular relates to a seismic isolation mechanism for prefabricated buildings. Background Art

[0002] In the field of building structural engineering, earthquakes, as a sudden and destructive natural disaster, pose a serious threat to the safety and stability of building structures. In order to reduce the damage caused by earthquakes to building structures and protect life and property, earthquake resistance and shock absorption technology has become one of the core research directions in the field of construction engineering.

[0003] At present, seismic bearings (such as laminated rubber bearings) are usually used to bear the upper structure load and dissipate seismic energy to achieve shock absorption of the upper structure. With the promotion of prefabricated and assembled buildings, connection nodes and assembly connection technology have become key factors affecting the seismic performance of structures. The high-strength connections between prefabricated components must meet the bearing capacity and ductility requirements under earthquakes. When modular structures form an overall system through unit combination, their node design must also adapt to the coordinated deformation between units to ensure the overall working performance of the structure. The seismic effect of existing prefabricated building wall panels is average, and the noise reduction effect is poor, which needs further improvement. Utility Model Content

[0006] The assembly plate is provided with slurry outlet holes and grouting holes, both of which are connected to the interior of the cross-shaped trough;

[0007] Two support blocks are placed between the two crossbeams. The support blocks are composed of a U-shaped block and a protrusion fixed to the U-shaped block. The openings of the two support blocks are both facing the center of the wall panel, and the protrusion is located between the two vertical panels on the same side.

[0008] The top and bottom surfaces of the inner wall of the wall panel are fixed with two vertical poles, the side walls of the vertical poles are fixed with the cross beam, the side walls of the vertical poles are threaded with threaded sleeves, and the two ends of the support block abut against the side walls of the two vertical poles. When the threaded sleeve rotates upward or downward, its top or bottom end abuts against the top or bottom end of the inner wall of the U-shaped block.

[0009] Furthermore, the locking piece is composed of a threaded column and a nut. A plurality of first screw holes are opened through the wall panel, and a plurality of second screw holes are opened through the assembly plate. The inner walls of the first screw holes and the second screw holes are threadedly installed with threaded columns, and the outer walls at both ends of the threaded columns are threadedly installed with nuts.

[0010] Furthermore, limiting holes are formed through the four corner edges of the wall panel, and limiting columns are fixedly connected to the four corner edges of one end of the assembly plate close to the wall panel, and the side walls of the limiting columns are fitted with the inner walls of the limiting holes.

[0011] Furthermore, the shock absorbing mechanism includes a bottom block fixed to the inner wall of the wall panel, a shock absorber fixed to the bottom block, a U-shaped support block fixed to the output end of the shock absorber, and a crossbeam fixed to the inner wall of the U-shaped support block.

[0012] Furthermore, grouting grooves are provided through the top and bottom ends of the support block.

[0013] Furthermore, the two ends of the U-shaped support block close to the center of the wall panel are respectively in contact with the two right-angled corners of the beam.

[0014] Furthermore, the top and bottom surfaces of the inner wall of the wall panel are provided with a guide mechanism for guiding the shock-absorbing mechanism, the guide mechanism includes a first fixed block fixed to the inner wall of the wall panel, one end of the first fixed column is fixed to the side wall of the first fixed block, the other end of the first fixed column is fixed to the side wall of the bottom block, the end of the first fixed block close to the center of the wall panel is fixed to the limiting body, a through hole is opened on the limiting body, one end of the second fixed column is fixed to the side wall of the U-shaped support block, the other end of the second fixed column is fixed to the second fixed block, the second fixed block is fixed to a sliding rod, and the sliding rod is slidably arranged on the inner wall of the through hole.

[0015] Beneficial effects of the utility model:

[0016] 1. When an earthquake occurs, the wall panels are subjected to vibration loads, and the shock absorbers in the shock-absorbing mechanism will expand and contract vertically, driving the U-shaped support blocks and beams to move up and down synchronously. The two sides of the beams fit against the assembly plates, and the two ends fit against the vertical plates. The vertical plates will limit excessive horizontal displacement of the beams, while the ends of the U-shaped support blocks near the center of the wall panels abut against the right-angled corners of the beams, further restricting the deformation direction of the beams. The shock absorbers absorb seismic energy by expanding and contracting, and the fit between the beams, vertical plates, and assembly plates ensures uniform load transfer, solving the problem of mediocre earthquake resistance of existing prefabricated building wall panels.

[0017] 2. When the threaded sleeve on the vertical pole is rotated, the threaded sleeve will move up and down along the vertical pole, and its top or bottom end will abut against the concave surface of the U-shaped block of the support block, thereby adjusting the force state of the support block. The convex block of the support block is located between the vertical plates. The vertical plates limit the horizontal displacement of the support block, so that the support block forms a stable support for the crossbeam, and cooperates with the crossbeam and shock-absorbing mechanism to disperse the seismic load, which can avoid local stress concentration and further optimize the seismic effect.

[0018] 3. Grouting is performed into the cross-shaped trough through the grouting holes of the assembly plate. The slurry will flow through the grouting groove of the support block and eventually discharge the air from the slurry outlet to ensure that the slurry fills the entire trough. After the slurry solidifies, the area enclosed by the four vertical plates, two beams, two assembly plates and the inner wall of the wall panel forms a continuous whole, reducing the gaps between the components and blocking the path for sound to propagate through the gaps, thus solving the problem of poor noise reduction effect of existing prefabricated building wall panels.

DETAILED DESCRIPTION

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] Example 1: Please refer to Figure 1-Figure 7 , a seismic isolation mechanism of an assembled building, comprising a wall panel 1 and assembly plates 2 arranged at both ends of the wall panel 1, the two assembly plates 2 being mounted on the wall panel 1 by locking members, the wall panel 1 being frame-shaped, the top and bottom surfaces of the inner wall of the wall panel 1 being provided with a seismic isolation mechanism, a cross beam 12 being provided at the output end of the seismic isolation mechanism, the cross beam 12 being T-shaped, the two sides of the cross beam 12 being respectively fitted with one end of the two assembly plates 2 close to each other, vertical plates 19 being fixed at the four corners of the inner wall of the wall panel 1, the two ends of the cross beam 12 being respectively fitted with one end of the corresponding two vertical plates 19 close to each other, the four vertical plates 19, the two cross beams 12, the two assembly plates 2 and the inner wall of the wall panel 1 together enclose a cross-shaped trough;

[0029] The assembly plate 2 is provided with a slurry outlet hole 6 and a grouting hole 7, both of which are in communication with the interior of the cross-shaped trough body;

[0030] Two support blocks 22 are placed between the two cross beams 12. The support blocks 22 are composed of a U-shaped block and a protrusion fixed to the U-shaped block. The openings of the two support blocks 22 are both facing the center of the wall panel 1. The protrusion is located between the two vertical plates 19 on the same side.

[0031] Two vertical rods 20 are fixed to the top and bottom surfaces of the inner wall of the wall panel 1. The side walls of the vertical rods 20 are fixed to the cross beam 12. The side walls of the vertical rods 20 are threadedly installed with threaded sleeves 21. The two ends of the support block 22 abut against the side walls of the two vertical rods 20. When the threaded sleeve 21 rotates upward or downward, its top or bottom end abuts against the top or bottom end of the inner wall of the U-shaped block.

[0032] When in use, place the two support blocks 22 between the two beams 12 so that the protrusions of the support blocks 22 enter between the two vertical plates 19 on the same side, then manually rotate the threaded sleeve 21 to make it move upward or downward, so that the top or bottom end of the threaded sleeve 21 abuts against the top or bottom surface of the inner wall of the support block 22, and then place the two assembly plates 2 at both ends of the wall panel 1 respectively, so that the limiting column 5 enters the limiting hole 8, and then use the threaded column 3 to threadably install it on the wall panel 1 and the assembly plate 2, and then lock the two ends of the threaded column 3 with the nut 4, so that the two assembly plates 2 and the wall panel 1 are installed together, and then inject concrete slurry into the cross-shaped trough through the grouting hole 7, so that the support block 22 and the two beams 12 can be cast into an integrated structure, thereby improving the stability of the wall panel 1.

[0033] See also Figure 1In this embodiment, the locking member is composed of a threaded column 3 and a nut 4. A plurality of first screw holes are opened through the wall panel 1, and a plurality of second screw holes are opened through the assembly plate 2. The inner walls of the first screw holes and the second screw holes are threadedly installed with threaded columns 3, and the outer walls of both ends of the threaded column 3 are threadedly installed with nuts 4. After the threaded column 3 passes through the first screw hole of the wall panel 1 and the second screw hole of the assembly plate 2, it is doubly fixed by the nuts 4 at both ends, which can enhance the tightness of the connection between the wall panel 1 and the assembly plate 2, avoid relative looseness of the two during an earthquake, and improve the overall seismic stability of the structure.

[0034] See also Figure 1-Figure 3 In this embodiment, limiting holes 8 are provided through the four corner edges of the wall panel 1, and limiting columns 5 are fixedly connected to the four corner edges of one end of the assembly plate 2 close to the wall panel 1. The side walls of the limiting columns 5 fit the inner walls of the limiting holes 8. During assembly, the limiting columns 5 are inserted into the limiting holes 8, and the wall panel 1 and the assembly plate 2 can be pre-positioned at the initial stage of installation to ensure that the first screw hole and the second screw hole are accurately aligned, while limiting the relative displacement of the two in the horizontal direction. In combination with the threaded column 3 and the nut 4, the connection accuracy and seismic resistance are further improved.

[0035] See also Figure 1 、 Figure 3 and Figure 4 In this embodiment, the shock-absorbing mechanism includes a bottom block 9 fixed to the inner wall of the wall panel 1, a shock absorber 10 fixed to the bottom block 9, a U-shaped support block 11 fixed to the output end of the shock absorber 10, and a crossbeam 12 fixed to the inner wall of the U-shaped support block 11. The bottom block 9 provides stable support for the shock absorber 10. The shock absorber 10 can directly absorb seismic energy by expansion and contraction. The U-shaped support block 11 can evenly transfer the force of the shock absorber 10 to the crossbeam 12. At the same time, the U-shaped structure forms a wrapping constraint on the crossbeam 12, ensuring that the crossbeam 12 is stably deformed when subjected to force, thereby improving the energy dissipation of the shock-absorbing mechanism.

[0036] See also Figure 1 、 Figure 6 and Figure 7 In this embodiment, grouting grooves 23 are provided at the top and bottom ends of the support block 22. During grouting, the slurry can flow through the grouting grooves 23 at the upper and lower ends of the support block 22, ensuring that the slurry inside the cross-shaped groove is more fully filled, reducing residual bubbles, and making the support block 22 more closely integrated with the surrounding structure after solidification, thereby enhancing the overall stiffness and improving the noise reduction effect.

[0037] See also Figure 1 and Figure 4In this embodiment, the two ends of the U-shaped support block 11 close to the center of the wall panel 1 respectively abut against the two right-angled corners of the beam 12. This structure can limit the excessive torsion of the beam 12 in the horizontal direction, so that the beam 12 only moves synchronously with the shock absorber 10 in the vertical direction when subjected to force, avoiding deformation and damage of the beam 12 due to stress concentration at the corners, extending its service life and effectively ensuring its seismic performance.

[0038] Example 2: Please refer to Figure 5 On the basis of Example 1, the present application provides a technical solution: the top and bottom surfaces of the inner wall of the wall panel 1 are both provided with a guide mechanism for guiding the shock absorbing mechanism, the guide mechanism includes a first fixing block 14 fixed to the inner wall of the wall panel 1, one end of a first fixing column 13 is fixed to the side wall of the first fixing block 14, the other end of the first fixing column 13 is fixed to the side wall of the bottom block 9, the end of the first fixing block 14 close to the center of the wall panel 1 is fixed to a limiting body 15, a through hole is opened on the limiting body 15, and the side wall of the U-shaped support block 11 is fixed to the There is a second fixed column 16 at one end, and the other end of the second fixed column 16 is fixedly connected to a second fixed block 17, and a sliding rod 18 is fixed to the second fixed block 17. The sliding rod 18 is slidably arranged on the inner wall of the through hole. The first fixed column 13 and the first fixed block 14 enhance the installation stability of the bottom block 9. When the sliding rod 18 slides along the through hole of the limit body 15, it can constrain the movement direction of the U-shaped support block 11 and the shock absorber 10 to prevent them from deflecting or shaking during an earthquake, ensuring that the shock absorbing mechanism always absorbs energy efficiently in the vertical direction, thereby improving the reliability of earthquake resistance.

[0039] Working principle: When in use, first place the two support blocks 22 between the two crossbeams 12, so that the protrusions of the support blocks 22 are located between the two vertical plates 19 on the same side, and the two ends of the support blocks 22 abut against the side walls of the vertical poles 20. Manually rotate the threaded sleeve 21 on the vertical pole 20 to move it up or down until the top or bottom end of the threaded sleeve 21 abuts against the top or bottom end of the concave surface of the support block 22, thereby pre-fixing the support blocks 22;

[0040] Then, place the two assembly plates 2 at the two ends of the wall panel 1 respectively, insert the limiting posts 5 on the assembly plates 2 into the limiting holes 8 of the wall panel 1 to complete pre-positioning, then pass the threaded posts 3 through the first screw holes of the wall panel 1 and the second screw holes of the assembly plates 2, and tighten the ends of the threaded posts 3 with nuts 4 to firmly connect the assembly plates 2 to the wall panel 1;

[0041] At this time, the vertical plate 19, the cross beam 12, and the assembly plate 2 on the inner wall of the wall panel 1 together enclose a cross-shaped trough. Concrete slurry is injected into the cross-shaped trough through the grouting holes 7 on the assembly plate 2. The slurry flows through the grouting groove 23 of the support block 22 to fill the entire trough. Air is discharged from the slurry outlet 6. After the slurry solidifies, the support block 22, the cross beam 12, the vertical plate 19, the assembly plate 2 and the wall panel 1 form an integrated structure.

[0042] When an earthquake occurs, the wall panel 1 is vibrated, and the shock-absorbing mechanisms on the top and bottom surfaces of its inner wall begin to work. The bottom block 9 provides stable support for the shock absorber 10. The shock absorber 10 absorbs earthquake energy by expanding and contracting, and transmits the force to the beam 12 through the U-shaped support block 11. The end of the U-shaped support block 11 close to the center of the wall panel 1 abuts the right-angle corner of the beam 12, and cooperates with the fit between the two sides of the beam 12 and the assembly plate 2, and the fit between the two ends and the vertical plates 19 to limit the horizontal displacement and torsion of the beam 12, ensuring that it moves stably in the vertical direction with the shock absorber 10. The vertical rod 20 and the support block 22 work together to share the load and avoid local stress concentration.

[0043] If a guiding mechanism is provided, the U-shaped support block 11 will drive the second fixed column 16, the second fixed block 17 and the slide rod 18 to move synchronously when it moves, and the slide rod 18 will slide along the through hole of the limit body 15. With the auxiliary support of the first fixed column 13 and the first fixed block 14, the movement direction of the shock absorber 10 and the U-shaped support block 11 will be further constrained to prevent them from deflecting, thereby ensuring that the shock absorbing mechanism absorbs energy efficiently. At the same time, the continuum formed by grouting in the overall structure reduces gaps, effectively blocking sound propagation, thereby achieving the dual effects of shock isolation and noise reduction of the structure.
