Description

Technical Field

[0001] This utility model relates to the field of cofferdam construction technology, and in particular to a prefabricated cofferdam support connector. Background Technology

[0002] In cofferdam construction, sheet piles are a commonly used support structure. Traditional cofferdam support connections typically use welding for fixing, but this method suffers from low installation efficiency, difficulty in adjustment, and inconvenience in disassembly. Especially in prefabricated cofferdams, rapid installation and disassembly are required to adapt to different construction conditions. Existing connectors often lack flexibility and cannot accommodate minor deformations or displacements of the sheet piles, resulting in insufficient support stability. Furthermore, the tensioning and fixing mechanisms are complex, increasing construction time and costs. Therefore, a new type of connector is needed that simplifies the installation process, improves adjustment convenience, and enhances support stability. Summary of the Invention

[0003] This utility model aims to address the shortcomings of existing technologies by providing a prefabricated cofferdam support connector.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a prefabricated cofferdam support connector, comprising a first U-shaped connector fixed to the top of the concave side of a convex steel sheet pile, a second C-shaped connector fixed to the top of the convex side of the concave steel sheet pile, and a support rod detachably installed between two rows of steel sheet piles. An I-beam is slidably inserted into the second connector, and the concave steel sheet pile and the I-beam are fixed together by bolts. A sliding sleeve is slidably fitted on the side of the I-beam away from the second connector, and a connecting block is provided on the side of the sliding sleeve away from the concave steel sheet pile. A slot is provided on the top of the connecting block. The support rod is inserted into the slots of two opposite connecting blocks between the two rows of steel sheet piles, and the support rod and the connecting block are fixed together by bolts. A tensioning mechanism is provided between the I-beam and the first connector.

[0005] Specifically, the sliding sleeve has a sliding plate that contacts the web of the I-beam, and the sliding plate is threaded with bolts, which are tightened and fixed.

[0006] Specifically, the tensioning mechanism includes a threaded sleeve, an adjusting rod with reverse threads connected to both ends of the threaded sleeve, an insert plate installed at the end of the adjusting rod, and a third insert plate in the shape of an inverted S inserted into the side of the I-beam near the first insert plate. The top of the opposing surfaces of the first and third insert plates are provided with grooves corresponding to the adjusting rods. The two insert plates are respectively inserted into the corresponding first and third insert plates, and the adjusting rod is inserted into the groove. Tensioning is achieved by rotating the threaded sleeve.

[0007] Specifically, rubber anti-slip pads are provided on the contact surfaces of the first and third connectors and the plug plate.

[0008] Specifically, the third connector is bolted to the I-beam.

[0009] The beneficial effects of this utility model are as follows: By setting up a sliding I-beam, a sliding sleeve, and a tensioning mechanism, this utility model achieves rapid installation and position adjustment of the support rod, improving construction efficiency. The tensioning mechanism uses a threaded sleeve and an adjusting rod, which allows for convenient adjustment of the tension force and ensures the stability of the support. The design of the first and second connectors makes the connection between the sheet pile and the connector more robust. The sliding sleeve is bolted to the I-beam, allowing for flexible adjustment of the support rod's position. The overall structure is simple, easy to operate, and suitable for various prefabricated cofferdam construction scenarios. Attached Figure Description

[0016] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0018] like Figures 1-5 As shown, a prefabricated cofferdam support connector includes a first connector 2 in a U-shape fixed to the top of the concave side of a convex sheet pile 1, a second connector 4 in a C-shape fixed to the top of the convex side of a concave sheet pile 3, and a support rod 5 detachably installed between two rows of sheet piles. An I-beam 6 is slidably inserted into the second connector 4, and the concave sheet pile 3 and the I-beam 6 are fixed together by bolts. This design allows the I-beam 6 to slide within the second connector 4, facilitating position adjustment, and then is fixed by bolts, ensuring the connection's strength and adjustability.

[0019] A sliding sleeve 7 is slidably fitted on the side of the I-beam 6 away from the second connector 4. A sliding plate 10 extends from the sliding sleeve 7 and contacts the web of the I-beam 6. Bolts are threaded onto the sliding plate 10, and the plate is secured by tightening the bolts. The sliding sleeve 7 can slide on the I-beam 6, thereby adjusting the position of the support rod 5 to accommodate sheet piles with different spacings. The bolt-locking mechanism is simple to operate and provides reliable fixation.

[0020] The sliding sleeve 7 has a connecting block 8 on the side opposite to the concave steel sheet pile 3. The top of the connecting block 8 has a slot 9. The support rod 5 is inserted into the slots 9 of the two opposite connecting blocks 8 between the double rows of steel sheet piles, and the support rod 5 and the connecting block 8 are fixed together by bolts. The slot 9 design makes the support rod 5 easy to install and remove, and the bolt fixing ensures the stability of the support rod 5 and prevents it from falling off.

[0021] A tensioning mechanism is provided between the I-beam 6 and the first connector 2. The tensioning mechanism includes a threaded sleeve 11, an adjusting rod 12 with reverse threads connected to both ends of the threaded sleeve 11, an insert plate 13 installed at the end of the adjusting rod 12, and a third connector 14 in an inverted S-shape inserted into the side of the I-beam 6 near the first connector 2. The top of the opposing surfaces of the first connector 2 and the third connector 14 are provided with sliding grooves corresponding to the adjusting rod 12. The two insert plates 13 are respectively inserted into the corresponding first connector 2 and third connector 14, and the adjusting rod 12 is inserted into the sliding groove. Tensioning is achieved by rotating the threaded sleeve 11. The tensioning mechanism achieves synchronous adjustment through forward and reverse threads, which can quickly tighten or loosen, adapt to different working conditions, and improve the tightness and stability of the connection.

[0022] Rubber anti-slip pads are provided on the contact surfaces of the first connector 2, the third connector 14, and the insert plate 13. These rubber anti-slip pads increase friction, preventing the insert plate 13 from sliding, and also act as a buffer, reducing wear between metal parts. The third connector 14 is bolted to the I-beam 6, ensuring that the third connector 14 is securely fixed to the I-beam 6 and guaranteeing the effective transmission of the tensioning mechanism.

[0023] In operation, the I-beam 6 is inserted into the second connector 4 and slid to the appropriate position, then secured with bolts. Next, the sliding sleeve 7 is fitted onto the I-beam 6, adjusted to the desired position, and tightened with bolts. The matching support rod 5 is inserted into the slots 9 of the connecting blocks 8 on both sides and secured with bolts. Finally, the third connector 14 is fitted onto the I-beam 6, and the insert plates 13 are inserted into the first connector 2 and the third connector 14 respectively. By rotating the threaded sleeve 11, the tensioning mechanism is adjusted to tighten the I-beam 6 and the first connector 2, thereby enhancing the stability of the overall structure. The entire installation process is simple, quick, and easy to adjust, greatly improving construction efficiency.
