Description

Technical Field

[0001] This utility model relates to the field of earthquake-resistant wall technology, specifically to an earthquake-resistant building. Background Technology

[0002] Precast concrete slabs, also known as precast concrete panels, are concrete slabs prefabricated in a factory using molds. They are characterized by standardized and efficient production. Precast slabs are commonly used in building structures such as floor slabs, wall panels, partitions, and slope protection, providing reliable support and protection. Their advantages include rapid installation, stable quality, environmental friendliness, energy efficiency, and high durability.

[0003] However, existing walls composed of precast slabs are relatively weak in terms of seismic performance, mainly due to defects in the connection method between adjacent precast slabs. Traditionally, precast slabs are often spliced ​​by binding steel bars before pouring concrete, but this connection method is not strong enough and is easily damaged under strong external forces such as earthquakes, resulting in poor seismic performance. Therefore, a seismic-resistant building method has been proposed. Utility Model Content

[0004] The purpose of this utility model is to provide an earthquake-resistant building in order to solve the problem that existing walls composed of precast panels have weak seismic performance.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] An earthquake-resistant building includes a precast slab 1 and a precast slab 2. Several equally spaced reinforcing bars 1 are fixedly installed on the side of the precast slab 1 near the precast slab 2. A concrete block is fixedly installed on each reinforcing bar 1, and a slot is formed on the top of each concrete block. Several equally spaced reinforcing bars 2 are fixedly installed on the side of the precast slab 2 near the precast slab 1. A connecting block is fixedly installed on each reinforcing bar 2, and a locking block is fixedly installed on the side wall of each connecting block. These locking blocks are movably installed inside adjacent slots. Expansion bolts 1 are threadedly connected to both sides of each concrete block, and each expansion bolt 1 is threadedly connected to the interior of an adjacent locking block.

[0007] Furthermore, each of the card blocks has a limiting groove at its bottom, and a limiting rod is fixedly installed inside each limiting groove. Each limiting rod is fixedly installed inside the adjacent card groove.

[0008] Furthermore, a strip rod is provided above the connecting block, and each connecting block is fixedly installed at the bottom of the strip rod. An expansion bolt is threaded onto the strip rod at the position of each concrete block, and each expansion bolt is threaded into the interior of the adjacent concrete block.

[0009] Furthermore, each concrete block is provided with an embedded component on the side near the second precast slab, and each connecting block is provided with an embedded component on the side near the first precast slab. The embedded component includes a long rod, each concrete block is fixedly connected to an adjacent long rod, each connecting block is fixedly connected to an adjacent long rod, and two short rods are fixedly installed on both sides of each long rod. A crossbar is fixedly installed at the end of each short rod away from the adjacent long rod.

[0010] Furthermore, the pre-embedded component also includes mounting holes. Each long rod has a mounting hole at one end, and a rotating shaft is threaded into the interior of each mounting hole. A connecting rod is fixedly installed at one end of each rotating shaft. A limiting rod II is fixedly installed at one end of each connecting rod. A hexagonal sleeve is fixedly installed on each connecting rod. A semicircular block is provided on the side of each limiting rod II away from the adjacent connecting rod. A limiting groove II is provided on the side of each semicircular block near the adjacent limiting rod II. Each limiting rod II is movably installed inside the adjacent limiting groove II. Each precast slab I is fixedly connected to the adjacent semicircular block, and each precast slab II is fixedly connected to the adjacent semicircular block.

[0011] Furthermore, the hollow area inside the card slot is a convex block structure, and the card block is adapted to the hollow area inside the card slot.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model first places precast slab one and precast slab two in the designated installation positions, and makes each locking block movably installed inside the adjacent locking slot. Then, the workers turn each expansion screw one in turn, so that each expansion screw one is threaded to the inside of the adjacent locking block, and each concrete block is connected to the adjacent connecting block. Finally, the workers pour concrete in the middle of precast slab one and precast slab two. Compared with the traditional steel bar binding method, the installation is faster, more convenient and more stable.

[0024] like Figures 1 to 5 As shown, an earthquake-resistant building includes a precast slab 1 and a precast slab 2. Several equally spaced reinforcing bars 3 are fixedly installed on the side of the precast slab 1 near the precast slab 2. A concrete block 4 is fixedly installed on each reinforcing bar 3, and a slot 5 is formed on the top of each concrete block 4. Several equally spaced reinforcing bars 6 are fixedly installed on the side of the precast slab 2 near the precast slab 1. A connecting block 7 is fixedly installed on each reinforcing bar 6, and a locking block 8 is fixedly installed on the side wall of each connecting block 7. These locking blocks 8 are movably installed inside adjacent slots 5. Expansion bolts 9 are threaded to both sides of each concrete block 4, and each expansion bolt 9 is threaded to the inside of an adjacent locking block 8. It should be noted that the precast slab 1 and precast slab 2 are first placed in their designated installation positions, and each... The locking blocks 8 are all movably installed inside the adjacent locking slots 5. Then, the workers rotate each expansion screw 9 in sequence, so that each expansion screw 9 is threaded into the interior of the adjacent locking block 8, and each concrete block 4 is connected to the adjacent connecting block 7. Finally, the workers pour concrete in the middle of the precast slab 1 and the precast slab 2. Compared with the traditional steel bar binding method, the installation is faster, more convenient and more stable. In the event of an earthquake, the structure between the precast slab 1 and the precast slab 2 will not easily loosen. At the same time, the structure between the precast slab 1 and the precast slab 2 also acts as a skeleton for the concrete poured in the middle. The structure between the precast slab 1 and the precast slab 2 and the poured concrete are tightly combined, which improves the overall stability of the structure, can withstand greater impact, and improves the seismic performance.

[0025] like Figures 1 to 4 As shown, each card block 8 has a limiting groove 11 at its bottom, and a limiting rod 10 is fixedly installed inside each limiting groove 11. Each limiting rod 10 is fixedly installed inside the adjacent card slot 5. It should be noted that while each card block 8 is movably installed inside the corresponding card slot 5, each limiting rod 10 also needs to be engaged with the inside of the adjacent limiting groove 11. By using the cooperation of the limiting rod 10 and the limiting groove 11, the installation position of the card block 8 can be restricted to a certain extent, and the connection stability of the card block 8 inside the card slot 5 can be ensured.

[0026] like Figures 1 to 4As shown, a strip rod 12 is provided above the connecting block 7. Each connecting block 7 is fixedly installed at the bottom of the strip rod 12. An expansion screw 13 is threadedly connected to the position of each concrete block 4 on the strip rod 12. Each expansion screw 13 is threadedly connected to the interior of the adjacent concrete block 4. It should be noted that after each locking block 8 is movably installed inside the corresponding locking slot 5, each expansion screw 13 is rotated in sequence, so that each expansion screw 13 is threadedly connected to the interior of the adjacent concrete block 4, thereby connecting the strip rod 12 to each concrete block 4, which can further enhance the stability of the connection between each concrete block 4 and the adjacent connecting block 7.

[0027] like Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, each concrete block 4 is provided with an embedded component 14 on the side near the precast slab 2, and each connecting block 7 is provided with an embedded component 14 on the side near the precast slab 1. The embedded component 14 includes a long rod 1401. Each concrete block 4 is fixedly connected to the adjacent long rod 1401, and each connecting block 7 is fixedly connected to the adjacent long rod 1401. Two short rods 1402 are fixedly installed on both sides of each long rod 1401, and a crossbar 1403 is fixedly installed at the end of each short rod 1402 away from the adjacent long rod 1401. It should be noted that after concrete is poured between the precast slab 1 and the precast slab 2, the long rods 1401, short rods 1402, and crossbars 1403 can all act as a skeleton in the concrete, further ensuring the connection stability between the precast slab 1 and the precast slab 2.

[0028] like Figure 1 , Figure 2 , Figure 4 , Figure 5As shown, the pre-embedded component 14 also includes mounting holes 1404. Each long rod 1401 has a mounting hole 1404 at one end. A rotating shaft 1405 is threaded into the interior of each mounting hole 1404. A connecting rod 1406 is fixedly mounted at one end of each rotating shaft 1405. A limiting rod 1407 is fixedly mounted at one end of each connecting rod 1406. A hexagonal sleeve 1408 is fixedly mounted on each connecting rod 1406. A semi-circular block 1409 is provided on the side of each limiting rod 1407 away from the adjacent connecting rod 1406. A limiting groove 1410 is provided on the side of each semi-circular block 1409 close to the adjacent limiting rod 1407. Each limiting rod 1407 is movably installed inside the adjacent limiting groove 1410. Each precast slab 1 is fixedly connected to the adjacent semi-circular block 1409. Next, each precast slab 2 is fixedly connected to the adjacent semicircular block 1409. It should be noted that before the concrete is poured, after each locking block 8 is movably installed inside the corresponding locking groove 5, each limiting rod 1407 is placed inside the adjacent limiting groove 1410. Then, each hexagonal sleeve 1408 is rotated, and each hexagonal sleeve 1408 drives the corresponding rotating shaft 1405 and connecting rod 1406 to rotate at a certain angle, so that each limiting rod 1407 rotates vertically inside the corresponding limiting groove 1410. Then, concrete is poured between the precast slab 1 and the precast slab 2. Since the poured concrete restricts the rotation of the limiting rod 1407, the limiting rod 1407 will not loosen from the corresponding limiting groove 1410, further ensuring the connection stability of the precast slab 1 and the precast slab 2.

[0029] like Figure 3 , Figure 4 As shown, the hollow area inside the slot 5 is a convex block structure. The card block 8 is adapted to the hollow area inside the slot 5. It should be noted that the card block 8 is a convex block structure. When the card block 8 is movably installed inside the slot 5, it can ensure that the card block 8 will not easily shift inside the slot 5.

[0030] In summary:

[0031] First, precast slab 1 and precast slab 2 are placed in their designated installation positions, ensuring that each locking block 8 is movably installed inside the adjacent locking slot 5. Then, the workers rotate each expansion bolt 9 in sequence, so that each expansion bolt 9 is threaded into the interior of the adjacent locking block 8, connecting each concrete block 4 to the adjacent connecting block 7. Finally, the workers pour concrete between precast slab 1 and precast slab 2. Compared with the traditional steel bar binding method, this installation is faster, more convenient, and more stable. In the event of an earthquake, the structure between precast slab 1 and precast slab 2 will not easily loosen. At the same time, the structure between precast slab 1 and precast slab 2 also acts as a skeleton for the concrete poured in the middle. The structure between precast slab 1 and precast slab 2 and the poured concrete are tightly integrated, improving the overall stability of the structure, which can withstand greater impact forces and enhance seismic performance.
