Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to pre-embedded wall ties. Background Technology

[0002] Wall ties are components that enhance the stability of other structures by connecting to reliable fixed ends. In construction engineering, they are used to connect scaffolding to the main building structure and can transmit tensile and compressive forces. Wall ties enhance the overall stability of scaffolding by creating wall-attached connections, and connecting them to concrete walls reinforces the concrete surface.

[0003] As shown in the reference case "A Pre-embedded Wall Tie" (Announcement No. CN221236387U), this method eliminates the need for pre-embedded steel pipes, thus not affecting the quality of the main structure and saving on subsequent cutting, grouting, and repair costs. It also eliminates the need for installation through shear walls, avoiding the risk of external wall leakage caused by later wall repairs or inadequate repairs. The entire process of pre-embedding, installation, use, and removal does not affect any other procedures. Installation and removal are convenient, and all external components can be recycled and reused, reducing costs.

[0004] According to the above reference materials, the above device uses double-ended screws to fix the pre-embedded components in the corresponding positions of the template. After the concrete is poured, the double-ended screws are removed, and the fasteners are connected to the fixing screws and tightened into the pre-embedded components. The fasteners connect the external scaffolding system to achieve the purpose of wall ties. However, when installing the wall ties, the connection between the wall ties and the scaffolding and concrete wall is not stable enough and is prone to loosening due to external forces. This makes it inconvenient to install the wall ties stably and reduces the effectiveness of the device. Utility Model Content

[0005] Therefore, it is necessary to provide pre-embedded wall ties to address the problem of inconvenient and unstable installation of wall ties.

[0006] The device includes an embedded part, one end of which is threadedly connected to a connecting bolt. A steel pipe is provided on one side of the connecting bolt, and a fixing mechanism is provided on the outer wall of the steel pipe. The fixing mechanism includes a first fixing member installed at both ends of the steel pipe. A second fixing member is fixedly connected to one side of one of the first fixing members. A locking block is slidably connected to the other side of the first fixing member and one side of the inner wall of the second fixing member. A first adjusting bolt is threadedly connected to the other side of the first fixing member and one side of the second fixing member. One end of the first adjusting bolt is rotatably connected to one side of the locking block. A reinforcing component is provided on one side of the other first fixing member.

[0007] In one embodiment, the fixing mechanism further includes two guide rods fixedly connected to one side of the locking block, one end of each guide rod being slidably connected to the inner wall of the first fixing member, and the two guide rods being respectively disposed on both sides of the first adjusting bolt.

[0008] In one embodiment, two anti-slip plates are fixedly connected to both sides of the inner wall of the first and second fixing members.

[0009] In one embodiment, the first fixing member and the second fixing member are rotatably connected to one side of the top of the fixing bolt, and one end of the fixing bolt is threaded with a nut.

[0010] In one embodiment, the reinforcement component includes a fixing block fixedly connected to one side of another first fixing member, and a limit plate is slidably connected to one side of the inner wall of the fixing block.

[0011] In one embodiment, a second adjusting bolt is threaded onto one side of the fixing block, and one end of the second adjusting bolt passes through the fixing block and is rotatably connected to the limiting plate.

[0012] In one embodiment, two positioning rods are fixedly connected to one side of the limiting plate, and the positioning rods are slidably connected to the inner wall of the fixing block. The two fixing blocks are respectively disposed on both sides of the second adjusting bolt.

[0013] Beneficial effects

[0014] 1. In the aforementioned pre-embedded wall tie, the two first and second fixing parts improve the friction coefficient between the first and second fixing parts and the steel pipe and scaffold pole through the anti-slip plate on the inner wall, thereby improving the stability of the first and second fixing parts. The locking block on one side of the inner wall of the first and second fixing parts can be moved to one side by the first adjusting bolt to clamp and fix the steel pipe and scaffold pole. The inner wall of the locking block is V-shaped, which can improve the stability of the first and second fixing parts. Two guide rods can position and guide the locking block. The first and second fixing parts are composed of two fasteners and are hinged to each other. The first and second fixing parts can be installed by the cooperation of fixing bolts and nuts, which can improve the stability of the pre-embedded wall tie and ensure stable installation of the wall tie.

[0015] 2. When installing with the embedded parts and connecting bolts, the fixing block on one side of the other second fixing part is fitted onto the connecting bolt. The second adjusting bolt cooperates with the fixing block to drive the limiting plate to move to one side to clamp and fix the connecting bolt, thereby improving the connection effect between the steel pipe and the embedded parts. The two positioning rods can position and guide the limiting plate, which can improve the connection stability of the embedded wall tie. Attached Figure Description

[0028] The following is combined Figures 1-4 This invention describes the pre-embedded wall tie component.

[0029] In one embodiment, the pre-embedded wall tie includes an embedded part 100, one end of which is threadedly connected to a connecting bolt 200. A steel pipe 300 is provided on one side of the connecting bolt 200, and a fixing mechanism 400 is provided on the outer wall of the steel pipe 300. The fixing mechanism 400 includes first fixing members 410 installed at both ends of the steel pipe 300. One side of one of the first fixing members 410 is fixedly connected to a second fixing member 420. The other side of the first fixing member 410 and one side of the inner wall of the second fixing member 420 are slidably connected to a locking block 430. The other side of the first fixing member 410 and one side of the second fixing member 420 are threadedly connected to a first adjusting bolt 440. One end of the first adjusting bolt 440 is rotatably connected to one side of the locking block 430. A reinforcing component 480 is provided on one side of the other first fixing member 410.

[0030] It should be noted that the pre-embedded wall tie consists of pre-embedded bolts, fasteners, and bolts. The pre-embedded bolts are installed inside the concrete wall, and the fasteners are installed on the pre-embedded bolts. Then, the fasteners are fastened to the steel structure with bolts. Another fastener can be used to connect it to the scaffold pole. The first fixing member 410 and the second fixing member 420 can clamp and fix the steel pipe 300 and the scaffold pole through the anti-slip plate 460 on the inner wall and the clamping block 430, thereby improving the installation effect of the fasteners. The limiting plate 482 in the fixing block 481 is stably connected to the pre-embedded member 100 through the second adjusting bolt 483. The fixing mechanism 400 and the reinforcing component 480 can reinforce and optimize the pre-embedded wall tie without affecting its normal use.

[0031] like Figure 2 and Figure 3 As shown, the fixing mechanism 400 also includes two guide rods 450 fixedly connected to one side of the locking block 430. One end of the guide rod 450 is slidably connected to the inner wall of the first fixing member 410. The two guide rods 450 are respectively set on both sides of the first adjusting bolt 440. Two anti-slip plates 460 are fixedly connected to both sides of the inner wall of the first fixing member 410 and the second fixing member 420. A fixing bolt 470 is rotatably connected to one side of the top of the first fixing member 410 and the second fixing member 420. A nut is threadedly connected to one end of the fixing bolt 470.

[0032] In this embodiment, the first fixing member 410 and the second fixing member 420 can be used to install and fix the steel pipe 300 and the scaffold pole by the fixing bolt 470 and the nut. The anti-slip plate 460 on the inner wall of the first fixing member 410 and the second fixing member 420 can increase the friction coefficient between the first fixing member 410 and the second fixing member 420 and the steel pipe 300 and the scaffold pole. The first adjusting bolt 440 drives the clamping block 430 to clamp and fix the steel pipe 300 and the scaffold pole. The two guide rods 450 can guide and support the clamping block 430, which can stably install the pre-embedded wall tie and improve the reinforcement of the pre-embedded wall tie.

[0033] like Figure 4 As shown, the reinforcement component 480 includes a fixing block 481 fixedly connected to one side of another first fixing member 410. A limiting plate 482 is slidably connected to one side of the inner wall of the fixing block 481. A second adjusting bolt 483 is threadedly connected to one side of the fixing block 481. One end of the second adjusting bolt 483 passes through the fixing block 481 and is rotatably connected to the limiting plate 482. Two positioning rods 484 are fixedly connected to one side of the limiting plate 482. The positioning rods 484 are slidably connected to the inner wall of the fixing block 481. The two fixing blocks 481 are respectively located on both sides of the second adjusting bolt 483.

[0034] In this embodiment, another first fixing member 410 is installed on the outer wall of the connecting bolt 200 through the fixing block 481, which can connect the embedded part 100. Rotating the second adjusting bolt 483 and the fixing block 481 threadedly connects the limiting plate 482 to one side, which can clamp the connecting bolt 200. The two positioning rods 484 can guide and support the limiting plate 482, which can stably connect the embedded wall tie and improve the use effect of the embedded wall tie.

[0035] Working principle: The embedded part 100 is installed in the concrete wall. The connecting bolt 200 passes through the fixing block 481 and is threaded to the inner wall of the embedded part 100. The second adjusting bolt 483 is manually rotated and threaded to the fixing block 481, which drives the limiting plate 482 to move to one side to clamp and fix the connecting bolt 200. Two first fixing parts 410 are installed at both ends of the steel pipe 300. The first fixing parts 410 are installed by manually rotating the fixing bolt 470 and threaded to the nut. The second fixing part 420 is connected to the scaffold pole. The second fixing part 420 is installed by the top fixing bolt 470 and nut. The first adjusting bolt 440 on one side of the first fixing part 410 and the second fixing part 420 is manually rotated and threaded to the fixing part, which drives the clamping block 430 to move to one side to clamp and fix the steel pipe 300 and the scaffold pole.

[0036] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
