Description

Technical Field

[0001] This utility model belongs to the field of precast shear wall technology, specifically relating to a precast shear wall connection structure. Background Technology

[0002] Precast shear walls are wall structures manufactured in factories by pouring reinforced concrete into steel molds to form a single, monolithic wall structure. These precast wall structures are then assembled on-site to form the overall structure of a building. Precast shear walls are typically made of reinforced concrete and ordinary concrete, and are characterized by high strength, high stiffness, and high stability.

[0003] In the actual process of joining precast shear walls, a guide plate is usually pre-installed to ensure that the two wall sections can be accurately and efficiently joined together. This guide plate plays a crucial role; it acts like an invisible track, guiding the two precast shear walls along its designated path. This design greatly simplifies the joining process, improves construction efficiency, and ensures that the joined precast shear walls remain relatively flush.

[0004] However, it is worth noting that after the precast shear walls are connected by guide plates, the operators still need to make several small adjustments to ensure that the two connected precast shear walls maintain a high degree of horizontal consistency in both the lateral and longitudinal directions. This task also puts a considerable burden on the operators, thus increasing the difficulty of connecting the precast shear walls. Utility Model Content

[0005] The purpose of this utility model is to provide a connection structure for precast shear walls, which aims to solve the problem that after the precast shear walls are connected by guide plates, operators still need to make multiple small adjustments to ensure that the two connected precast shear walls maintain a high degree of horizontal consistency in both the lateral and longitudinal directions. This task also places a considerable burden on the operators, thereby increasing the difficulty of connecting precast shear walls.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a prefabricated shear wall connection structure, comprising a first wall, a second wall connected to one side of the first wall, and a fitting block fixedly provided on the outer wall of the joint end of the first wall and the second wall;

[0007] The interlocking block is inserted into the interior of the second wall. Two insert rods are movably inserted into the top of the second wall near the end that connects with the first wall, and the two insert rods are completely inserted into the interior of the second wall.

[0008] In order to enable the insert to be smoothly inserted into the slot, as a prefabricated shear wall connection structure of this utility model, preferably, a slot is also provided on the outer wall of the first wall on one side of the interlocking block, and the slot is a fan-shaped structure;

[0009] An insert is fixedly installed on the outer wall of the connection end between the second wall and the first wall, and four fitting grooves are equally spaced on the outer wall of the second wall on one side of the insert;

[0010] The size of the insert is adapted to the size of the slot.

[0011] To facilitate the smooth insertion of the interlocking blocks into the interlocking slots, as a prefabricated shear wall connection structure of this utility model, preferably, four interlocking blocks are arranged at equal intervals, each interlocking block has two second insertion holes through it, and each interlocking block has a beveled edge on the side facing the slot.

[0012] The top of the second wall has two first insertion holes, and each first insertion hole is connected to the interior of the fitting groove.

[0013] In order to ensure that the interlocking blocks and interlocking slots can be fixed inside the interlocking slots after docking, as a prefabricated shear wall connection structure of this utility model, preferably, the four interlocking blocks are respectively adapted to one interlocking slot, and the insertion rod penetrates into the interior of the second wall from the interior of the second wall, and the insertion rod is simultaneously inserted into the four interlocking blocks.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] When connecting the first wall and the second wall, first fix the second wall in the installation position, then move the first wall closer to the second wall. When the first wall and the second wall are connected, the slots and fitting blocks on the first wall will connect with the inserts and fitting grooves on the second wall. During this connection process, the slots and inserts will gradually align with the center through the arc edges set on them, so that the first wall and the second wall can maintain a good horizontal connection state after they are connected.

[0016] In addition, the mating block after docking will be inserted into the mating groove, and then the plug rod will be inserted into the first and second plug holes, so that the mating block can be fixed inside the mating groove, thereby fixing the first wall and the second wall together after docking.

[0017] Therefore, in practical use, the combination of the above two technical solutions can improve the accuracy and stability of the connection between the first wall and the second wall, thereby simplifying the connection process and facilitating actual operation. Attached Figure Description

[0023] 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.

[0024] Please see Figure 1-3 The present invention provides the following technical solution: a prefabricated shear wall connection structure, including a first wall 1, a second wall 2 connected to one side of the first wall 1, and a fitting block 3 fixedly provided on the outer wall of the joint end of the first wall 1 and the second wall 2;

[0025] Both the first wall 1 and the second wall 2 are precast shear walls. The first wall 1 and the second wall 2 are reinforced with steel bars and concrete and poured into steel plate molds to form a whole wall structure.

[0026] The interlocking block 3 is inserted into the interior of the second wall 2. Two plug rods 4 are movably inserted into the top of the second wall 2 near the end that connects with the first wall 1, and the two plug rods 4 are completely inserted into the interior of the second wall 2.

[0027] Preferably, a slot 11 is provided on the outer wall of the first wall 1 on one side of the interlocking block 3, and the slot 11 has a fan-shaped structure;

[0028] An insert 21 is fixedly installed on the outer wall of the connection end between the second wall 2 and the first wall 1. Four fitting grooves 22 are equally spaced on the outer wall of the second wall 2 on one side of the insert 21.

[0029] The dimensions of the insert 21 are adapted to the dimensions of the slot 11.

[0030] In practical use, the longitudinal length of the insert 21 is the same as the longitudinal length of the first wall 1. After the insert 21 and the slot 11 are connected, they will be completely inserted into the interior of the slot 11, so that the connecting surfaces of the first wall 1 and the second wall 2 can maintain a normal connection effect.

[0031] Preferably, four interlocking blocks 3 are evenly spaced, and two second insertion holes 31 are opened through each interlocking block 3. Each interlocking block 3 has a beveled edge 32 on the side facing the slot 11.

[0032] The top of the second wall 2 is provided with two first insertion holes 23, and each first insertion hole 23 is connected to the interior of the fitting groove 22.

[0033] In practical use, the fitting groove 22 has a connecting surface that is opposite to the beveled edge 32. One end of the outer wall of the fitting block 3 is an arc-shaped structure, so that the fitting block 3 can slide into the interior of the fitting groove 22 more smoothly when docking.

[0034] Preferably, the four fitting blocks 3 are respectively adapted to a fitting groove 22, and the insertion rod 4 penetrates into the interior of the second wall 2 from the interior of the second wall 2, and the insertion rod 4 is simultaneously inserted into the four fitting blocks 3.

[0035] In practical use, the first step in connecting the first wall 1 and the second wall 2 is to securely install the second wall 2 in the predetermined position, ensuring it remains stable. Then, the first wall 1 is moved closer to the second wall 2. As they approach contact and dock, the slot 11 and insert 21 on the first wall 1, and the fitting groove 22 and fitting block 3 on the second wall 2, engage in a mating process. During this docking, the slot 11 and insert 21, with their respective designed curved edges, gradually adjust and naturally align towards the center as they approach each other. This design ensures that the first wall 1 and the second wall 2 achieve a high degree of horizontality and maintain a perfect docking state after docking.

[0036] Furthermore, as the first wall 1 and the second wall 2 are joined, the interlocking block 3 will be precisely embedded into the interlocking groove 22 of the second wall 2, forming a preliminary fixing effect. To further enhance this fixing effect, the insertion rod 4 needs to be precisely inserted into the pre-designed first insertion hole 23 and second insertion hole 31 on the first wall 1 and the interlocking block 3. This step not only ensures that the interlocking block 3 can be firmly fixed inside the interlocking groove 22, but also, through physical connection, tightly combines the joined first wall 1 and second wall 2 together, forming a stable whole.

[0037] In summary, this series of meticulously designed docking and fixing steps greatly improves the accuracy and stability of the connection between the first wall 1 and the second wall 2. This high degree of accuracy and stability provides a solid foundation for subsequent construction procedures, making the entire construction process more convenient and efficient.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
