Description

Technical Field

[0001] The utility model relates to the technical field of T-beam maintenance, in particular to a T-beam anti-overturning support frame. Background Art

[0002] A beam bridge whose load-bearing structure is composed of the upper flange and beam ribs of reinforced concrete is called a T-beam, named because the cross-sectional shape of the main beam is like the English letter T. The compression zone of the T-beam section is made of pressure-resistant concrete to make the flange plate and also serve as the bridge deck; the tension zone uses steel bars or prestressed steel bars to bear the tension. As the width of the wing plate increases, the height of the compression zone of the T-shaped cross-section can be reduced, the internal force moment arm increases, and the required tensile reinforcement area is reduced. After the existing T-beams are removed from the formwork, they are usually placed on a support frame composed of square timber for maintenance, but due to factors such as the quality of the square timber, weather, and humidity conditions on site, the stability of the square timber support is difficult to guarantee. In addition, after the maintenance is completed, some of the square timber needs to be removed to facilitate the lifting of the T-beam, but due to the volume and weight of the T-beam, it is also very inconvenient to remove the square timber.

[0003] The Chinese patent with the authorization announcement number CN217707072U applied by the applicant recently discloses an adjustable prefabricated T-beam storage support frame, which includes at least two equally spaced fixed seats, at least two fixed legs arranged on the bottom surface of the fixed seats, an adjustment seat arranged between two adjacent fixed seats, at least two lifting legs arranged on the bottom surface of the adjustment seat, and a telescopic clamping plate arranged between the adjustment seat and two adjacent fixed seats, the lifting path of the adjustment seat passes through the gap between two adjacent fixed seats, and the two moving ends of the telescopic clamping plate are respectively provided with positioning magnetic blocks that are magnetically adsorbed to the fixed seat. The utility model adopts a fixed seat and an adjustment seat mainly made of metal material instead of square wood for support, and arranges a liftable and detachable adjustment seat at the lifting point, which facilitates the lifting operation of the T-beam while ensuring the stability of the T-beam support.

[0004] In the actual maintenance process, in order to improve the space utilization rate of the maintenance site, 2~3 T-beam prefabricated parts are usually placed on the above-mentioned support frame in a stacked manner. Due to the geometric characteristics of the prefabricated T-beam itself, the center of gravity is relatively high, and it is very easy to overturn during production and storage. If the support measures are improper, once overturning occurs, it will cause safety accidents and economic losses, which will have a major impact on the construction project. Therefore, square wood or steel pipes are usually used to support the two wings when storing beams. Square wood support uses wood as a supporting component, which is usually used for structures with relatively less force and load. The advantages of square wood support are easy material acquisition, convenient and simple construction, low cost, and suitable for temporary support. The disadvantages are unstable structure, inaccurate size, weak bearing capacity, easy deformation, easy decay, cannot be reused, and waste of materials; steel bar support uses steel as a supporting component, which is used to bear large loads of structural support or permanent support. The advantages of steel bar support are stable structure, accurate size, strong bearing capacity, not easy to deform, not easy to corrode, reusable, and material saving. The disadvantages are high cost, complex installation, need for professional operation, and difficult to disassemble. Utility Model Content

The bottom surface of the support seat is arranged relative to the ground or the top surface of the T-beam, and the top surface is arranged relative to the bottom surface of the T-beam. The rotation axis of the swing pair is horizontal and perpendicular to the length direction of the bidirectional screw pair. The limit terminal is arranged relative to the T-beam wing plate.

After the T-beam is installed, the angle between the bidirectional screw pair and the support seat can be directly adjusted by flipping and locking the rotating component of the swing pair, and the limit terminal is directed toward the inner edge of the T-beam wing. The bidirectional screw pair is then rotated so that the two moving ends of the bidirectional screw pair are moved away from each other and the limit terminal moves close to the T-beam wing. In this process, the limit terminal can be rotated alone to make the limit terminal match the contact surface of the T-beam wing. After the adjustment is completed After completion, the support system composed of the swing pair, the two-way screw pair and the limit terminal forms a triangular support on both sides of the T-beam, which has the advantages of stable support and strong bearing capacity; when disassembling, the two-way screw pair is rotated and retracted in sequence, and the swing pair is flipped to make the limit terminal detach from the T-beam wing plate, and then the T-beam is lifted by hoisting; in this process, a support system with adjustable installation angle and length is formed by the swing pair, the two-way screw pair and the limit terminal, and the support seat is used to provide interval support between the bottom surface and the T-beam, or between the upper and lower T-beams.

[0028] In order to make the technical means, creative features, objectives and functions achieved by the present invention clearer and easier to understand, the present invention is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0029] Reference Figure 1 , is a T-beam anti-overturning support frame disclosed by the utility model, the support frame is composed of steel, and includes a support seat 1, a pair of swinging pairs 2 symmetrically arranged on the support seat 1 and capable of self-locking, a bidirectional screw pair 3 with one moving end arranged at the swinging end of the swinging pair 2, and a limit terminal 4 arranged at the other moving end of the bidirectional screw pair 3. Among them, the bottom surface of the support seat 1 is arranged relative to the ground or the top surface of the T-beam, and the top surface is arranged relative to the bottom surface of the T-beam, the rotation axis of the swinging pair 2 is horizontal and vertical relative to the length direction of the bidirectional screw pair 3, and the limit terminal 4 is arranged relative to the T-beam wing plate.

[0030] A support system with adjustable installation angle and length is formed by a swing pair 2, a bidirectional screw pair 3 and a limit terminal 4, and is assisted by a support seat 1 to provide interval support between the bottom surface and the T-beam, or between the upper and lower T-beams. While facilitating the stacking of T-beams and not affecting the lifting of T-beams, it has the advantages of easy installation and disassembly, strong bearing capacity, easy adjustment of support position and reusability.

[0031] Reference Figure 2 First, the top surface of the support base 1 is provided with two internal thread sleeves 11, and the end surface of the internal thread sleeve 11 and the top surface of the support base 1 are approximately in the same plane. The lifting ring can be threadedly installed on the internal thread sleeve 11, which is convenient for lifting the support frame.

[0032] Reference Figure 3 , Secondly, the swing pair 2 includes a gasket 21 arranged on the support seat 1, a pair of mounting plates 22 arranged on the gasket 21 and spaced apart from each other, a fastener 23 that is rotationally locked on the pair of mounting plates 22, and a swing plate 24 that is inserted between the pair of mounting plates 22 and arranged on the fastener 23. Among them, the fastener 23 includes a bolt that is interspaced and penetrates the pair of mounting plates 22 and contacts the surface of one of the mounting plates 22, and a nut (not shown in the figure) that is threadedly connected to the bolt and contacts the surface of the other mounting plate 22. When adjusting the angle, loosen the fastener 23 and flip the swing plate 24 to adjust the angle between the bidirectional screw pair 3 and the support seat 1. After the adjustment is completed, tighten the fastener 23, which can directly limit the swing plate 24 from rotating relative to the mounting plate 22. The operation is simple and quick.

[0033] Again, the bidirectional screw pair 3 includes a bidirectional threaded sleeve 31, and a lower threaded steel bar 32 and an upper threaded steel bar 33 respectively threadedly connected to two sections of internal threads of the bidirectional threaded sleeve 31. Among them, the lower threaded steel bar 32 is arranged on the swing piece 24, and the upper threaded steel bar 33 is arranged on the limit terminal 4. The bidirectional threaded sleeve 31, the lower threaded steel bar 32 and the upper threaded steel bar 33 are all common materials in the production site, and the use cost is low.

After the T-beam is installed, the angle between the bidirectional screw pair 3 and the support seat 1 can be directly adjusted by flipping and locking the rotating member of the swing pair 2, and the limit terminal 4 is directed toward the inner edge of the T-beam wing plate, and then the bidirectional screw pair 3 is rotated to make the two moving ends of the bidirectional screw pair 3 move away from each other and the limit terminal 4 moves close to the T-beam wing plate. In this process, the limit terminal 4 can be rotated alone to make the limit terminal 4 match the contact surface of the T-beam wing plate. After the adjustment is completed, the support system composed of the swing pair 2, the bidirectional screw pair 3 and the limit terminal 4 forms a triangular support on both sides of the T-beam, which has the advantages of stable support and strong bearing capacity. When disassembling, the bidirectional screw pair 3 is rotated and retracted in turn, and the swing pair 2 is flipped to make the limit terminal 4 separate from the T-beam wing plate, and then the T-beam is lifted by hoisting.
