Description

Technical Field

[0001] This utility model relates to the field of construction technology of cast-in-place cap beam support, and in particular to the connection device between prefabricated steel bracket and rectangular pier support wall clamp. Background Technology

[0002] The cast-in-place cap beams in construction projects are mostly large-span, long-cantilever prestressed cast-in-place cap beams, which require high-precision supports. The steel structure of the cast-in-place cap beam support is large, making installation difficult. Traditional cap beam support erection connects the support to the embedded parts of the pier column to form a stable structure. However, traditional wall connection methods have problems such as high requirements for pre-embedding accuracy and significant impact on the overall landscape effect of the pier column. Summary of the Invention

[0003] This utility model aims to address the shortcomings of existing technologies by providing a prefabricated steel bracket and rectangular pier support clamp connection device.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a prefabricated steel bracket and rectangular pier support clamp connection device, including ear plates, I-beams, threaded steel bars, locking nuts, and a spacing adjustment mechanism. Two pairs of I-beams are respectively arranged on one side of the rectangular pier column facing the steel bracket. Their ends are connected by threaded steel bars and tightened with locking nuts to form a rectangular frame clamp structure, which hugs the outer perimeter of the rectangular pier column. Ear plates are respectively installed on both sides of the opposite surfaces of the I-beams and the steel bracket. The spacing adjustment mechanism is movably installed between the corresponding ear plates to connect the steel bracket and the rectangular frame clamp structure to form an integral structure.

[0005] Specifically, a first connecting plate is welded to the outer side of the end flanges of a pair of I-beams. Angle steel and L-shaped rubber pads are provided on the first connecting plate that is in close contact with the rectangular pier. The rubber pads are in contact with the edges of the rectangular pier. The first connecting plate and the angle steel are provided with through holes corresponding to the threaded steel. The through holes correspond to the gap between the pair of I-beams. The threaded steel passes through the through holes and is fixed by tightening the locking nut.

[0006] Specifically, a pair of I-beams are welded to the outer side of the flanges of the rectangular pier with a second connecting plate adjacent to the first connecting plate. Ear plates are welded to the second connecting plate. Several stiffening plates are welded to the side walls of the angle between the ear plates and the second connecting plate, and between the ear plates and the steel bracket.

[0007] Specifically, the spacing adjustment mechanism includes a threaded sleeve with two lead screws connected by reverse threads on both sides. The ends of the lead screws are provided with C-shaped connecting brackets, which are inserted into the ear plate and movably connected by pins.

[0008] The beneficial effects of this utility model are as follows: This utility model, through its innovative clamp-type connection design, effectively solves the problems of high precision requirements, damage to the pier structure, and impact on the overall landscape associated with traditional pre-embedded parts. The device utilizes two pairs of I-beams, threaded steel bars, and locking nuts to form a rectangular frame clamp, which can tightly fit around the rectangular pier. Installation is convenient, requires no pre-embedding, significantly improves construction efficiency, and reduces the permanent impact on the pier. By setting a first connecting plate with angle steel and L-shaped rubber pads, not only is the strength of the connection node enhanced, but the concrete edges of the pier are also protected from pressure damage, improving the friction of the contact surface and the reliability of the overall connection. The welded design of the ear plate and stiffening plate effectively enhances local stiffness, ensuring the stability of the node under complex loads. The spacing adjustment mechanism adopts a bidirectional screw and threaded sleeve structure, realizing the fine-tuning function of the distance between the steel bracket and the pier, compensating for construction and installation errors, exhibiting strong adaptability, ensuring the accuracy of the bracket installation position, thereby improving the stability and safety of the entire cast-in-place cap beam support system.

[0017] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0019] like Figures 1-7 As shown, the prefabricated steel bracket and rectangular pier support clamp connection device includes ear plate 1, I-beam 2, threaded steel bar 3, locking nut 4, and spacing adjustment mechanism 5. Two pairs of I-beams 2 are respectively arranged on the side of the rectangular pier column 6 facing the steel bracket 7. Their ends are connected by threaded steel bars 3 and tightened with locking nuts 4 to form a rectangular frame clamp structure, which hugs the outer perimeter of the rectangular pier column 6. A first connecting plate 21 is welded to the outer side of the end flange of a pair of I-beams 2. Angle steel 22 and L-shaped rubber pads 23 are provided on the first connecting plate 21 that is in close contact with the rectangular pier column 6. The rubber pads 23 are in contact with the edges of the rectangular pier column 6. The first connecting plate 21 and angle steel 22 are provided with through holes 24 corresponding to the threaded steel bars 3. The through holes 24 correspond to the gap of a pair of I-beams 2. The threaded steel bars 3 pass through the through holes and are fixed by tightening the locking nuts 4.

[0020] This utility model effectively solves the problems of high precision requirements, damage to the pier structure, and impact on the overall landscape associated with traditional pre-embedded parts through an innovative clamp-type connection design. The device utilizes two pairs of I-beams 2, threaded steel bars 3, and locking nuts 4 to form a rectangular frame clamp, which can tightly fit around the rectangular pier 6. Installation is convenient, requires no pre-embedding, significantly improves construction efficiency, and reduces permanent impact on the pier. By incorporating a first connecting plate 21 with angle steel 22 and L-shaped rubber pads 23, the strength of the connection node is enhanced, and the concrete edges of the pier are protected from pressure damage, improving the friction of the contact surface and the reliability of the overall connection.

[0021] Ear plates 1 are respectively installed on both sides of the opposite face of the I-beam 2 and the steel bracket 7. The spacing adjustment mechanism 5 is movably installed between the corresponding ear plates 1 to connect the steel bracket 7 and the rectangular frame clamp structure to form an integral structure. A second connecting plate 25 adjacent to the first connecting plate 21 is welded to the outer side of the flange of a pair of I-beams away from the rectangular pier column 6. Ear plates 1 are welded to the second connecting plate 25. Several stiffening plates 11 are welded to the side wall of the included angle between ear plates 1 and the second connecting plate 25, and between ear plates 1 and the steel bracket 7. The stiffening plates 11 are welded to ear plates 1 themselves and also to the web of the steel bracket 7 and the second connecting plate 25 respectively to ensure a more secure connection of ear plates 1. The spacing adjustment mechanism 5 includes a threaded sleeve 51. Two lead screws 52 are connected to the two sides of the threaded sleeve 51 by reverse threads. The ends of the lead screws 52 are provided with C-shaped connecting frames 53. The connecting frames 53 are inserted into the ear plates 1 and movably connected by pins.

[0022] The welding design of the ear plate 1 and stiffening plate 11 effectively enhances the local stiffness and ensures the stability of the node under complex loads. The spacing adjustment mechanism 5 adopts a two-way screw rod 52 and threaded sleeve 51 structure, realizing the fine adjustment function of the distance between the steel bracket 6 and the pier column, compensating for construction and installation errors, with strong adaptability, ensuring the accuracy of the bracket installation position, thereby improving the stability and safety of the entire cast-in-place cap beam support system.

[0023] During installation, ear plates 1 and stiffening plates 11 are welded at 3m center-to-center distances on the upper chords of the steel bracket 7. Double-jointed I-beams 2 are welded together via a first connecting plate 21 and a second connecting plate 25. Angle steel 22 is welded onto the first connecting plate 21, and rubber pads 23 are installed. Through holes 24 are made at corresponding positions. The I-beams 2 are then installed on the rectangular pier 6, passing through φ32 precision-rolled threaded steel 3, and the locking nut 4 is tightened to secure the clamp to the pier. The connecting frame 53 is then connected to the ear plates 1 via pins. This invention has outstanding advantages such as reasonable structure, convenient assembly and disassembly, adjustability, reusability, no damage to the pier, and minimal impact on the landscape, demonstrating good economic benefits and promotional value.
