These beams are usually used to span the room to connect two walls to support various devices, such as hanging brackets, lamps, fans, curtains, hanging paintings, etc. However, since long-span concrete beams are easily affected by uneven force factors, their stress areas are deformed and cracks appear, affecting their structural performance and service life. Therefore, there is an urgent need for a long-span concrete beam anti-crack reinforcement structural device, whose goal is to provide an overall structural performance enhancement of the concrete beam and prevent cracks.

[0003] At present, most existing devices mainly use support members such as support rods or steel pipes fixed from the ground to provide support for large-span concrete beams to achieve the purpose of reinforcement. Some also have prefabricated steel beam sleeves on the outside of large-span concrete beams to strengthen the bending resistance of large-span concrete beams to achieve the purpose of reinforcement; however, there are some problems with the above method. First of all, when using support members such as steel pipes and vertical piles fixed on the ground, they will not only destroy the layout of the interior of the building, but also introduce obvious obstacles indoors, reducing the convenience and comfort of use. In addition, for the prefabricated steel beam sleeves installed on the outside of the large-span concrete beams, due to their heavy weight, they need to be suspended and fixed with the help of equipment such as cranes, which increases the complexity and cost of construction, especially in some indoor environments with limited space or equipment restrictions, the installation process becomes particularly difficult.

DETAILED DESCRIPTION

[0019] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] See also Figures 1 to 4 , the utility model provides a technical solution:

[0021] A large-span concrete beam anti-crack reinforcement structure device comprises a beam body 15, a reinforcement mechanism is arranged between the beam body 15 and the roof, through which an upward pulling force can be provided to the beam body 15 to achieve reinforcement of the beam body 15, thereby improving the structural stability and crack resistance of the beam body 15; the reinforcement mechanism comprises a bearing plate 1, in order to achieve a fixed connection between the bearing plate 1 and the roof, mounting holes are opened at the four end corners of the bearing plate 1, and fixing parts such as bolts or expansion nails can be installed in the holes to firmly fix the bearing plate 1 to the roof;

[0022] See attached Figure 1 and attached Figure 3 The bottom of the bearing plate 1 is connected with a rotating rod 3 through a detachable tension adjustment component, and the detachable tension adjustment component includes a first threaded rod 2 fixed at the middle position of the bottom of the bearing plate 1, and a thread groove adapted to the first threaded rod 2 is opened inside the rotating rod 3. Through the cooperation of the thread groove and the first threaded rod 2, not only can the rotating rod 3 be rotated on the outside of the first threaded rod 2 and threadedly connected with it, but also can be moved up and down on the outside of the first threaded rod 2; the bottom of the rotating rod 3 is connected with an L-shaped reinforcement plate 6 through a clamping component, and the top of the L-shaped reinforcement plate 6 fits the bottom of the beam body 15; as a preferred embodiment, since the surface of the beam body 15 may be uneven, in order to further increase the contact area between the L-shaped reinforcement plate 6 and the beam body 15, an elastic plate is arranged on the side of the L-shaped reinforcement plate 6 close to the beam body 15. When the L-shaped reinforcement plate 6 provides tension to the beam body 15, the elastic plate is deformed by force, thereby filling the gap between the L-shaped reinforcement plate 6 and the beam body 15, thereby increasing the contact area between the L-shaped reinforcement plate 6 and the beam body 15.

[0023] The clamping assembly includes a supporting block 4 rotatably connected to the bottom of the rotating rod 3, a first rotating groove 7 is opened on the outer side of the bottom of the rotating rod 3, a second rotating groove 8 is opened inside the supporting block 4, the first rotating groove 7 is located inside the second rotating groove 8, the rotating rod 3 and the supporting block 4 are rotatably connected through the setting of the first rotating groove 7 and the second rotating groove 8, a connecting block 5 is fixed on the outer side of the L-shaped reinforcement plate 6, a vertical sliding groove 9 adapted to the rotating rod 3 is opened inside the connecting block 5, a vertical positioning groove 10 adapted to the supporting block 4 is also opened on the connecting block 5, and the vertical sliding groove 9 is communicated with the vertical positioning groove 10.

[0024] First, according to the area of ​​the beam body 15 that needs to be reinforced, the number of uses of the device can be appropriately selected. When in use, the bearing plate 1 is aligned with the middle position of the beam body 15, and the bearing plate 1 is firmly fixed to the roof with bolts or expansion nails and other fixings. After fixation, it is only necessary to rotate the rotating rod 3 to make it threadedly connected with the first threaded rod 2, thereby completing the installation of the rotating rod 3, and observe the distance between the roof and the beam body 15, rotate the rotating rod 3 to make it move outside the first threaded rod 2, so as to realize the pre-adjustment of the height of the rotating rod 3; then, it is only necessary to lift the L-shaped reinforcement plate 6 to move the vertical slide groove 9 on the connecting block 5 to the outside of the rotating rod 3, and move the L-shaped reinforcement plate 6 downward to make the vertical slide groove 9 slide on the outside of the rotating rod 3, and at this time, the vertical positioning groove 10 slides to the outside of the bearing block 4, so that the connecting block 5 can be restricted by the bearing block 4, thereby completing the installation of the L-shaped reinforcement plate 6;

[0025] Since the height of the rotating rod 3 has been pre-adjusted, it is only necessary to fine-tune the height of the rotating rod 3 to move the L-shaped reinforcing plate 6 to the bottom of the beam body 15, thereby providing a pulling force for the middle position of the beam body 15, and reinforcing the beam body 15, thereby improving the stability and crack resistance of the beam body 15. During the process, since the bearing block 4 and the first threaded rod 2 are rotatably connected, the rotating rod 3 can be rotated with one hand using a tool, and the L-shaped reinforcing plate 6 can be supported with the other hand to align it with the beam body 15, thereby avoiding misalignment between the L-shaped reinforcing plate 6 and the beam body 15, and the pulling force provided by the L-shaped reinforcing plate 6 to the beam body 15 can also limit the downward movement of the beam body 15, and at the same time, the friction between the L-shaped reinforcing plate 6 and the beam body 15 can reduce the self-rotation of the L-shaped reinforcing plate 6; in summary: through the detachable tension adjustment component, when the bearing plate 1 is fixed to the wall, the rotating rod 3 thereon can be separated, which reduces the weight borne by the bearing plate 1, thereby facilitating the fixing of the bearing plate 1;

[0026] The height of the rotating rod 3 can be pre-adjusted by the detachable tension adjustment component, avoiding the need for a large adjustment due to increased load after the L-shaped reinforcement plate 6 is installed, thereby achieving rapid application of tension to the beam body 15, thereby strengthening the beam body 15 and improving the stability and crack resistance of the concrete beam;

[0027] By means of the clamping assembly, when the rotating rod 3 is connected to the first threaded rod 2, the L-shaped reinforcing plate 6 thereon can be separated, so that the number of parts on the rotating rod 3 is reduced, thereby reducing the burden on the rotating rod 3, facilitating the connection between the rotating rod 3 and the first threaded rod 2, and the L-shaped reinforcing plate 6 can be installed more quickly by means of the clamping assembly;

[0028] As a preferred embodiment, a universal mounting seat is provided on the bearing plate 1, and the universal mounting seat includes four threaded holes provided on the bearing plate 1, and the four threaded holes are respectively located at the four end corners of the bearing plate 1, and a second threaded rod 11 is threadedly connected in the threaded hole, and a connecting column 12 is fixed on the top of the second threaded rod 11, and a ball groove is provided inside the connecting column 12, and a ball 13 is installed in the ball groove, and a mounting plate 14 is fixed to the top of the ball 13 through the setting of the ball 13 and the ball groove. A through hole is provided at one end of the mounting plate 14, and a fixing member such as a bolt or an expansion nail can be installed therein to fix the bearing plate 1 to the roof;

[0029] According to the above structure, due to different roof structures, it may have an inclined surface or an uneven surface. The four second threaded rods 11 can be rotated according to the inclination of the roof, so that the four mounting plates 14 can be independently adjusted in height to match the height of the roof. The mounting plate 14 can be freely rotated and the angle can be adjusted by setting the ball joint between the mounting plate 14 and the connecting column 12, so that the top of the mounting plate 14 fits the inclined surface of the roof. At this time, the bearing plate 1 can be fixed to the roof by bolts or expansion nails.

[0030] When the roof structure is different, the universal mounting seat can be used to flexibly adjust the mounting plate 14 so that the mounting plate 14 fits the roof, so that the support plate 1 is not affected by the inclination or unevenness of the roof surface when it is fixed, thereby improving the applicability and practicality of the device.

[0031] The working principle of the above-mentioned large-span concrete beam anti-crack reinforcement structure device is as follows:

[0032] Align the bearing plate 1 with the middle position of the beam body 15, and use bolts or expansion nails to firmly fix the bearing plate 1 to the roof. After fixing, it is only necessary to rotate the rotating rod 3 to make it threadedly connected with the first threaded rod 2, thereby completing the installation of the rotating rod 3, and observe the distance between the roof and the beam body 15, rotate the rotating rod 3 to make it move to the outside of the first threaded rod 2, thereby realizing the pre-adjustment of the height of the rotating rod 3; then, it is only necessary to lift the L-shaped reinforcement plate 6 to move the vertical slide groove 9 on the connecting block 5 to the outside of the rotating rod 3, and move the L-shaped reinforcement plate 6 downward to make the vertical slide groove 9 slide on the outside of the rotating rod 3. At this time, the vertical positioning groove 10 slides to the outside of the bearing block 4, so that the connecting block 5 can be restricted by the bearing block 4, thereby completing the installation of the L-shaped reinforcement plate 6 and realizing the reinforcement of the beam body 15.
