Description

Technical Field

[0001] The utility model relates to the technical field of T-beam anti-prestressing technology, in particular to a T-beam anti-prestressing deformation structure. Background Art

[0002] Large-span T-beams are heavy and large in size. After installation, they will deform due to long-term use. In order to ensure the stability of the T-beam, prestressed design is required. Prestressing is the compressive stress pre-applied to the structure during construction to improve the service performance of the structure. During the service life of the structure, the pre-stressed stress can fully or partially offset the tensile stress caused by the load and avoid structural damage.

[0003] Traditional T-beams are not designed with anti-prestressed structures, or simply have welded steel plates at the bottom for anti-prestressed reinforcement, which has poor performance. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of traditional T-beams that have no anti-prestressed structure or simply set welded steel plates at the bottom for anti-prestressed reinforcement, resulting in poor use effect, and to propose a T-beam anti-prestressed deformation structure.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A T-beam anti-prestressed deformation structure includes a T-beam, two support plates are welded to the bottom of the T-beam, both support plates are provided with through holes, and adjustment and stretching mechanisms are movably installed in the two through holes. The same anti-prestressed mechanism is arranged between the two adjustment and stretching mechanisms, and the anti-prestressed mechanism is connected to the bottom of the T-beam.

[0007] Preferably, reinforcement plates are fixedly installed on both sides of the two support plates, and the reinforcement plates are welded to the bottom of the T-beam.

[0008] Preferably, the adjusting and stretching mechanism includes a screw rod, the screw rod is movably connected to the through hole, the outer side of the screw rod is threadedly connected to a nut, and the nut is located on the outer side of the support plate.

[0009] Preferably, a U-shaped part is welded to the inner end of the screw rod, and two through holes are provided on the U-shaped part. The two through holes located on the same vertical axis are installed with the same screw pin, and the U-shaped part is fixed to the anti-prestressed mechanism by the screw pin.

[0010] Preferably, the anti-prestress mechanism includes a carbon fiber plate and an alloy plate, the carbon fiber plate and the alloy plate are fixedly coated and connected, two matching holes are provided at both ends of the carbon fiber plate and the alloy plate, and screws are inserted into the matching holes to fix the carbon fiber plate and the alloy plate to the U-shaped part.

[0011] Preferably, the carbon fiber plate and the alloy plate are of arc-shaped design, a plurality of arc-shaped steel plates are fixedly mounted on the top of the carbon fiber plate, and the top of the arc-shaped steel plates is connected to the bottom of the T-beam.

[0012] Compared with the prior art, the advantages of the present invention are:

[0013] In this solution, the curved steel plate contacts the bottom of the T-beam and plays a supporting role. When the prestressing strength needs to be strengthened, the nuts are turned from both ends to tighten the two screw rods. The two screw rods drive the two U-shaped parts to straighten and tighten the carbon fiber plate and the alloy plate. When the carbon fiber plate and the alloy plate are straightened, the multiple curved steel plates are pushed upward. The multiple curved steel plates squeeze the bottom of the T-beam and reduce the deformation of the T-beam.

[0014] This solution adds carbon fiber plates, alloy plates and T-beams to form a whole, which improves the overall strength and can further reduce the deformation of the T-beam;

[0015] The utility model has a simple structure. When the carbon fiber plate and the alloy plate are stretched straight, the multiple curved steel plates are pushed upward, and the multiple curved steel plates squeeze the bottom of the T beam, thereby reducing the deformation degree of the T beam.

The anti-prestressed mechanism 4 is connected to the bottom of the T-beam 1. Reinforcement plates 22 are fixedly installed on both sides of the two support plates 21. The reinforcement plates 22 are welded to the bottom of the T-beam 1.

[0026] Reference Figure 2 、 Figure 4 In this embodiment, the adjusting and stretching mechanism 3 includes a screw rod 31, which is movably connected to the through hole 23. The outer side of the screw rod 31 is threadedly connected to a nut 32, and the nut 32 is located on the outer side of the support plate 21. A U-shaped part 33 is welded to the inner end of the screw rod 31, and two through holes 35 are provided on the U-shaped part 33. The two through holes 35 located on the same vertical axis are installed with the same screw pin 34, and the U-shaped part 33 is fixed to the anti-prestressed mechanism 4 through the screw pin 34.

[0027] Reference Figure 2 、 Figure 5 In this embodiment, the anti-prestress mechanism 4 includes a carbon fiber plate 41 and an alloy plate 42, and the carbon fiber plate 41 and the alloy plate 42 are fixedly coated and connected. Two matching holes 44 are provided at both ends of the carbon fiber plate 41 and the alloy plate 42, and the screw pin 34 penetrates the matching hole 44 to fix the carbon fiber plate 41 and the alloy plate 42 to the U-shaped part 33.
