Description

Technical Field

[0001] This utility model relates to precast shear walls, and in particular to a horizontal splicing structure for precast shear walls with high-strength soft cable ring connection. Background Technology

[0002] Precast shear walls are the main lateral force-resisting components in precast concrete shear wall structures, capable of withstanding earthquakes and wind loads. Horizontal joints in shear walls refer to the connection points between upper and lower layers of precast shear walls in an assembled shear wall structure. They are a crucial structural measure to ensure the integrity and stability of the shear wall structure, and their treatment and effectiveness directly affect the load-bearing capacity and safety performance of the entire structure.

[0003] The existing technology for horizontal joints in shear walls generally involves setting vertical connecting steel bars in the lower precast shear wall and connecting them to the connecting steel bars in the upper precast shear wall through sleeve grouting. The connecting steel bars can be set along the entire length of the precast shear wall or reliably anchored in the precast shear wall, and then concrete is poured for permanent connection. However, this connection method is relatively cumbersome and has low construction efficiency. Utility Model Content

The connector is used to connect the two ends of the first connecting cable to form a loop.

[0007] Preferably, the connector includes a connecting frame and two connecting plates. The connecting frame is fixedly connected to the second collar.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example 1: This example aims to propose a horizontal splice structure for prefabricated shear walls with high-strength soft cable ring connection.

[0016] according to Figures 1-4 As shown, it includes an upper shear wall 1, a lower shear wall 2, a floor slab, and connecting structures.

[0017] The upper shear wall 1 and the lower shear wall 2 are spaced apart vertically. The upper shear wall 1 is equipped with upper shear wall reinforcement 5, and the lower shear wall 2 is equipped with lower shear wall reinforcement 6.

[0018] The floor slab is located between the upper shear wall 1 and the lower shear wall 2. The floor slab includes a composite slab cast-in-place layer 13 and two precast base slabs 17. There is a gap between the two precast base slabs 17 for the first connecting cable 3 to pass through. The two precast base slabs 17 are detachably connected. The composite slab cast-in-place layer 13 is cast on the precast base slabs 17 and fills the gap between the precast base slabs 17. The composite slab cast-in-place layer 13 is formed by pouring concrete on top of the precast base slabs 17 and fills the gap between the precast base slabs 17.

[0019] The precast base slab 17 has reserved reinforcing bars. A second connecting cable 14 is provided between the two precast base slabs 17. The left and right ends of the second connecting cable 14 are respectively sleeved on the reserved reinforcing bars. The second connecting cable 14 and the adjacent first connecting cable 3 are staggered and perpendicular to each other. The second connecting cable 14 and the first connecting cable 3 are staggered to form a positioning opening. The composite slab cast-in-place layer 13 has cast reinforcing bars. The cast reinforcing bar cage is a double-layer structure. The first layer of the cast reinforcing bar cage extends in the left and right direction and is adapted to the length of the floor slab. The gap between the second layer of reinforcing bars and the two precast base slabs 17 is adapted. The second layer of reinforcing bars and the first layer of reinforcing bars are connected by reinforcing bars. The positioning opening is used to position the cast reinforcing bars. Specifically, the cast reinforcing bars of the second layer of reinforcing bars pass through the second connecting cable 14 and the first connecting cable 3 respectively, so that the second connecting cable 14 and the first connecting cable 3 limit the cast reinforcing bars, thereby positioning the cast reinforcing bars and suspending them. The lower structure positions the cast reinforcing bar cage by positioning the cast reinforcing bars.

[0020] The connecting structure is set between the upper shear wall reinforcement 5 and the lower shear wall reinforcement 6. The connecting structure includes multiple sets of connecting soft cables and anchoring reinforcement 4. The multiple sets of connecting soft cables are set at intervals. Each set of connecting soft cables includes two first connecting soft cables 3. The two first connecting soft cables 3 are respectively set on the upper shear wall reinforcement 5 and the lower shear wall reinforcement 6 through the installation parts. The anchoring reinforcement 4 is set between the upper shear wall reinforcement 5 and the lower shear wall reinforcement 6. The end of the first connecting soft cable 3 near the anchoring reinforcement 4 is sleeved with the outer surface of the anchoring reinforcement 4. The first connecting soft cable 3 passes through the gap between the two precast base plates 17.

[0021] The mounting components include a connector 7, a first collar 8, two first positioning ear plates 9, a second collar 10, and a second positioning ear plate 16. The first collar 8 is fixed to the upper shear wall reinforcement 5 or the lower shear wall reinforcement 6. The two first positioning ear plates 9 are fixedly connected to the first collar 8, and the positions of the two first positioning ear plates 9 are corresponding front and back. The second collar 10 is fixedly sleeved on the upper shear wall reinforcement 5 or the lower shear wall reinforcement 6, and the second collar 10 is located on the same side as the first collar 8.

[0022] The connector 7 is fixedly connected to the second collar 10, and the second positioning ear plate 16 is fixedly connected to the second collar 10. The connector 7 and the second positioning ear plate 16 are positioned in a front-to-back correspondence. Both the first positioning ear plate 9 and the second positioning ear plate 16 have through holes for the first connecting soft cable 3 to pass through. The connector 7 is used to connect the two ends of the first connecting soft cable 3 to form a cable loop.

[0023] The connector 7 includes a connector frame 11 and two connector plates 15. The connector frame 11 is fixedly connected to the second collar 10. The connector frame 11 has a slot that is open at both ends. The two connector plates 15 are fixedly connected to the two ends of the first connecting cable 3. The connector plates 15 are inserted into the slots. The connector frame 11 has two insertion holes. The connector plates 15 have locking holes. Locking bolts 12 are provided between the insertion holes and the locking holes.

[0024] Construction principle: First, the precast base plate 17 is installed at the top position. Then, the upper shear wall 1 is lifted. The lifting of the upper shear wall 1 drives the lower shear wall 2 to rise, so that the upper shear wall 1 and the lower shear wall 2 rise to the corresponding positions. Then, the cast steel reinforcement is positioned in the gap between the two precast base plates 17 through the second connecting soft cable 14 and the first connecting soft cable 3, so that the cast steel reinforcement cage is positioned. Then, the concrete is poured to connect the upper shear wall 1 to the floor slab.

[0025] This allows for the rapid hoisting of the upper shear wall 1 and the lower shear wall 2 to their designated positions. Furthermore, the upper shear wall 1 and the lower shear wall 2 are integrated with the floor slab through the precast base plate 17 and concrete pouring, thus enabling rapid construction and saving time.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims and not by the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
