Description

Technical Field

[0001] The present invention belongs to the technical field of construction engineering construction devices, and particularly relates to a novel embedded water-stop connecting wall member. Background Art

[0002] Connecting wall members often appear in the technical field of construction engineering construction. It refers to a member that strengthens the stability of other structures by connecting with a reliable fixed end. In construction engineering, it is used to connect the scaffolding frame body with the building main structure and can transfer tensile and compressive forces. The attached wall connection achieved by using connecting wall members plays a very important role in strengthening the overall stability of the scaffolding, improving its stable load-bearing capacity, and avoiding major accidents such as tipping or collapse.

[0003] Common connecting wall members generally include embedded parts, connecting wall members, right-angle fasteners, cross fasteners, and scaffolding. The embedded parts are generally made of steel pipes or steel bars. To ensure the installation of formworks such as shear walls and beams, they are usually vertically embedded above the shear walls and beams. When setting special components, PVC pipes can also be selected as the embedded parts, which are horizontally embedded through the wall for the subsequent setting of connecting wall members. However, the conventional connecting wall members vertically set on shear walls and beams cannot be set when encountering vertically continuous shear walls or extra-long and long-width continuous shear walls. Although the embedded parts of special structures passing through the wall can be implemented, "reserved scaffolding holes" will be left. After demolition, the construction of the "holes" is inconvenient and there are safety hazards. Moreover, the existence of the "holes" will bring potential leakage hazards to the structure, affecting the use function of the structure and leaving permanent quality hazards. Utility Model Content

[0004] The present utility model provides a novel embedded water-stop connecting wall member to solve the problems that existing conventional connecting wall members cannot be applied to vertically continuous shear wall structures and that the embedded parts passing through the wall will leave "scaffolding holes" during later demolition.

A plurality of installation holes are opened on the installation positioning plate; the special fastener includes a steel pipe locking buckle and a screw hole arranged on one side thereof. The steel pipe locking buckle is used to lock the connecting wall steel pipe. The connecting bolt passes through the screw hole and then screws in from the bottom opening of the galvanized steel pipe to connect the special fastener and the water-stop embedded part together.

[0006] Further, preferably, the steel pipe locking buckle includes an arc-shaped buckle seat and an arc-shaped buckle cover. One end of the arc-shaped buckle seat is hinged to one end of the arc-shaped buckle cover. A self-locking bolt is rotatably connected to the other end of the arc-shaped buckle seat. A card slot corresponding to the self-locking bolt is provided at the other end of the arc-shaped buckle cover. After the self-locking bolt is rotated and engaged into the card slot, the nut is tightened to lock.

[0007] Further, preferably, the screw hole is arranged on the outer side of the arc-shaped buckle seat.

[0008] Further, preferably, the diameter of the galvanized casing is 24.6 mm, the size of the water stop ring piece is 50×50 mm, and the size of the installation positioning plate is 60×60 mm.

[0009] Further, preferably, installation holes are provided at the four corners of the installation positioning plate, and the diameter of the installation holes is 5 mm.

[0010] The beneficial effects of the present utility model are as follows: The novel embedded water stop connecting wall member is convenient to install and disassemble, has good mechanical stress performance, can effectively transmit tension and pressure, forms a stable connecting wall device, is applicable to buildings or components of various structural types, and there are no problems of difficult disassembly and "frame holes" left after use. Moreover, the self-provided water stop ring piece can effectively prevent the risk of later leakage of the exterior wall, and has a significant effect on improving the construction efficiency and quality. In addition, the special fasteners and connecting wall steel pipes for disassembly can be reused, greatly reducing the construction cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] As Figure 1 shown, a new type of embedded water stop connecting wall member includes a special fastener 1, a water stop embedded part 2, and a connecting bolt 3 that connects the two together. Before construction, the water stop embedded part 2 is embedded in the structural wall 6 according to the plan and technical parameters, and then the special fastener 1 is connected to the water stop embedded part 2 through the connecting bolt 3. The special fastener 1 locks the connecting wall steel pipe 4, and the connecting wall steel pipe 4 is then fixedly connected to the outer frame vertical pole 5 through conventional scaffolding fasteners. In this way, the special fastener 1 and the water stop embedded part 2 can connect the outer frame vertical pole 5 into a whole, ensuring the overall stability of the outer frame.

[0021] As Figure 2As shown, the water-stop embedded part 2 includes a galvanized sleeve 21 (with a diameter of 24.6 mm) with an internal thread. The top thread of the galvanized sleeve 21 is connected with an adjustable bolt 22. The overall length of the water-stop embedded part 2 can be adjusted by the adjustable bolt 22 to adapt to the embedded depth of different structural walls 6. Moreover, the adjustable bolt 22 is T-shaped, which can also make the connection between the water-stop embedded part 2 and the structural wall 6 more stable; a water-stop ring piece 23 (50×50 mm) is provided in the middle of the galvanized sleeve 21 to prevent the risk of leakage of the external wall in the later stage; the bottom outer peripheral surface of the galvanized sleeve 21 is connected with an installation positioning plate 24 (60×60 mm), and installation holes 25 (with a diameter of 5 mm) are opened at the four corners of the installation positioning plate 24. After supporting the formwork, the installation of the water-stop embedded part 2 is completed through the installation holes 25.

[0022] like Figures 3 to 5 As shown, the special fastener 1 includes a steel pipe locking buckle 11 and a screw hole 12 arranged on one side thereof. The steel pipe locking buckle 11 is used to lock the wall-connected steel pipe 4. The steel pipe locking buckle 11 includes an arc-shaped buckle seat 111 and an arc-shaped buckle cover 112. One end of the arc-shaped buckle seat 111 is hinged to one end of the arc-shaped buckle cover 112. The other end of the arc-shaped buckle seat 111 is rotatably connected with a self-locking bolt 113. The other end of the arc-shaped buckle cover 112 is provided with a slot 114 corresponding to the self-locking bolt 113. After the self-locking bolt 113 is rotated and engaged with the slot 114, the nut 115 can be tightened to lock it. The screw hole 12 is arranged on the outside of the arc-shaped buckle seat 111 for the connection bolt 3 to pass through. During installation, the connection bolt 3 passes through the screw hole 12 and is screwed into the bottom opening of the galvanized sleeve 21, so that the special fastener 1 and the water-stop embedded part 2 can be connected.

[0023] Working principle: During installation, the embedded water-stop part 2 is fixed on the formwork of the structural wall 6 to be poured through the installation hole 25 (which can be matched with self-tapping screws or other common connectors) to complete the embedded installation; after the concrete is poured and the formwork is removed, the connecting bolt 3 passing through the screw hole 12 is screwed into the galvanized sleeve 21, and then the wall-connecting steel pipe 4 is put on the steel pipe locking buckle 11, the self-locking bolt 113 is closed, and the nut 115 is tightened to lock; finally, the wall-connecting steel pipe 4 is connected to the external frame upright through the scaffolding fastener to form a stable wall-connecting device. During later disassembly, there is no need to remove the embedded water-stop embedded part 2. It is only necessary to unscrew the connecting bolt 3 from the galvanized sleeve 21 to remove it, and the disassembled special fastener 1 and the wall-connecting steel pipe 4 can also be reused, which is conducive to reducing construction costs. In addition, the water-stop ring piece that comes with the embedded water-stop part 2 plays a water-stopping role and avoids the risk of leakage of the external wall in the later stage.
