When placed, the corners of the prefabricated beams and slabs are relatively fragile and easily damaged, and corner guards are needed to protect them to ensure the integrity of the corners. The existing corner guards are formed by bending steel plates or protective plates that match the beams and slabs, which are attached to the corners of the beams and slabs for protection. Targeted corner guards are required for beams and slabs of different sizes or corner angles. The corner guards are in hard contact with the corners of the prefabricated beams and slabs, and the contact surface and the corners of the beams and slabs produce friction, which will damage the corners and remain unchanged during installation.

[0015] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0016] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
[0017] like Figure 1-3 As shown, a prefabricated beam and slab corner protection device comprises a placing table 1, a flipping frame 2 and an adjustment protection assembly; the placing table 1 has a corresponding supporting force; the flipping frame 2 is rotatably mounted at one end of the placing table 1 and can be flipped onto the placing table 1; the frames on both sides extend along the length of the placing body and have a corresponding supporting force; the flipping frame 2 can be rotatably mounted at one end of the placing table 1 through a flipping axis, and the other end of the placing table 1 is provided with a foot 7 corresponding to the far end of the flipping frame 2; when the flipping frame 2 flips onto the placing table 1, the foot 7 supports the far end of the flipping frame 2; the flipping frame 2 can be U-shaped as a whole, and the two opposite lateral frames extend along the length direction of the placing table 1 and have a corresponding supporting force, and the corner guard 3 moves along the lateral frame through the sliding support block 6 to adjust the distance between the length directions. When the protection is released, after the sliding corner guard 3 is away from the corner, the flipping frame 2 is flipped, and the whole can be separated from the prefabricated beam and slab, which is convenient for the hoisting and transportation of the prefabricated beam and slab.
[0018] It should be noted that a limiting long rod 8 is assembled on the outer side of the lateral frame, and the sliding support block 6 is connected to the limiting foot 9, and the limiting foot 9 is slidably installed on the limiting long rod 8. When the sliding support block 6 moves, the limiting foot 9 slides along the limiting long rod 8, so that the movement of the corner guard 3 is more stable, and the outer wall of the limiting long rod 8 is equipped with a thread, and a limiting nut 10 corresponding to the limiting foot 9 is arranged on the limiting long rod 8, which is threadedly connected to the limiting long rod 8 and is used to limit the farthest position of the limiting foot 9 moving away from the beam and slab. After the corner guard 3 moves to a suitable position, the limiting nut 10 located on the outer side of the protective working surface of the corner guard 3 moves toward the outer side of the corner guard 3 and presses against the outer side of the corner guard 3 to position the corner guard 3.
[0019] In some preferred embodiments, the adjustment protection assembly includes a corner guard 3, which is slidably arranged on the two side frames of the flip frame through a sliding support block 6, and an expansion extrusion body 4 is installed at the angle of the protection working surface of the corner guard 3, and the expansion extrusion body 4 has a corresponding elastic deformation force; the expansion extrusion body 4 can be an expansion body made of sponge or polyurethane material, and has a corresponding elastic deformation force. When the corner guard 3 is squeezed close to the corner, it undergoes corresponding deformation to avoid excessive protection. Here, it is preferred that the corner guard 3 is set to 4, corresponding to the four corners of the prefabricated beam slab; the multi-stage telescopic rod 5 has a predetermined telescopic damping value, which is connected between the sliding support block 6 and the outer side of the corner guard 3, and when telescoping, the distance between the corner guards 3 along the width direction of the placement table 1 is adjusted. After the prefabricated beam is placed on the placement table 1, the position of the corner guard 3 on the lateral frame is adjusted along the length direction so that the corner guard 3 corresponds to the four corners of the prefabricated beam. At this time, the multi-stage telescopic rod 5 is stretched so that the inner side of the corner guard 3 completely fits the corner, and the expansion extrusion body 4 is squeezed and isolated between the corner guard 3 and the corner of the prefabricated beam to provide flexible protection for the corner.
[0020] In some preferred embodiments, further, the corner guard 3 is formed by connecting the sides of two protective plates, and a torsion spring is provided at the connection between the two protective plates of the corner guard 3, and the torsion spring is provided so that the corner guard 3 can be expanded to 180°. In the initial state, the two protective plates can fit together under the action of the torsion spring (after the expansion extrusion body 4 is assembled between the protective plates, the expansion extrusion body 4 can be squeezed, and the two protective plates cannot be completely fitted at this time), and can be stretched to a certain angle by the corners, and combined with the expansion extrusion body 4, it can better fit the different angles of the prefabricated beams and slabs. The corner guard 3 at the far end of the rotation can be provided with a torsion spring, or all four corner guards 3 can be provided with a torsion spring, and different corner guards 3 can be adjusted and replaced according to the actual protection operation requirements.
[0021] When in use, the device is placed in a suitable working position; the prefabricated beam is placed on the placing table 1, and the flip frame 2 is flipped so that the two side frames of the flip frame 2 are located on the two sides of the prefabricated beam. After the corner guard 3 is moved to a suitable position along the lateral frame, the multi-stage telescopic rod 5 is stretched so that the corner guard 3 is against the corner of the prefabricated beam (the corner guard 3 with a torsion spring can be unfolded when it is moved close to the corner, so that the corresponding protective door is against the corner, and then the corner guard 3 is moved). The corner guard 3 is adjusted twice to fit the corner of the prefabricated beam, and the corner squeezes the expansion extrusion body 4 inside the corner guard 3 to achieve flexible protection. When disassembly is required, loosen the limit nut 10, pull the corner guard 3 away from the corner along the limit long rod 8, and then flip the flip frame 2 to avoid affecting the lifting of the prefabricated beam.
[0022] Although the embodiments of the utility model have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the utility model, and the scope of the utility model is defined by the attached claims and their equivalents. In short, if those skilled in the art are inspired by them and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the scope of protection of the utility model.
