Description

Technical Field

[0001] This utility model relates to the field of building construction, and more specifically, to a T-beam hoisting and positioning device and a T-beam hoisting system. Background Technology

[0002] Once the precast beams are completed and meet design and specification requirements, they can be moved according to site conditions. Traditional methods for moving precast beams typically involve lifting with lifting rings or using a gantry crane. The wire ropes are secured to the lifting rings or caught under the beam. During gantry crane lifting, the connection between the beam and the wire rope is insulated with rubber to prevent damage. After securing the wire ropes, the beam is slowly lifted until it reaches a height of 1 meter from the support platform. The bottom of the beam is then cleaned, especially the surfaces where the beam ends contact the support plates, ensuring there is no concrete debris or other impurities. After cleaning the bottom and sides, the beam is lifted to a height of 2 meters above the ground. The gantry crane is then slowly moved to the storage area, where the beam is placed.

[0003] The inventors discovered during their research that the existing T-beam hoisting methods have at least the following drawbacks:

[0004] Lifting with lifting rings is problematic because the lifting ring bars are generally made of round steel. During the manufacturing process, the round steel needs to be bent into shape, and the bending radius is small, which can easily damage the molecular structure inside the steel bar, thereby reducing the yield strength of the steel bar. This can easily lead to the lifting ring bars breaking during the lifting process, resulting in safety problems such as beam falling.

[0005] Using the beam support method can easily lead to forgetting to install the corner guards on the beam, which can cause damage to the corners of the beam due to stress during the beam hoisting process. In severe cases, it can cause serious damage to the appearance and structure of the beam. Utility Model Content

[0006] The purpose of this utility model includes, for example, providing a T-beam hoisting and positioning device and a T-beam hoisting system, which can improve the safety of hoisting precast beams and is less likely to damage the appearance quality and structure of the precast beams.

[0007] The embodiments of this utility model can be implemented as follows:

[0008] In a first aspect, this utility model provides a T-beam hoisting and positioning device for installation on a precast beam, comprising:

[0009] The lifting rod, fixing components, and leveling components are provided; the lifting rod is provided with a lifting hole; the leveling components are provided with an abutting inclined surface, and an assembly through hole is provided on the abutting inclined surface, through which the lifting rod passes; the fixing components are fixedly connected to the lifting rod, and the fixing components and the lifting hole are distributed on opposite sides of the leveling components;

[0010] The lifting rod is used to pass through the precast hole on the precast beam. The lifting hole and the abutting slope are located on both sides of the precast beam. The abutting slope is used to contact the bottom inclined side of the precast beam.

[0011] In an optional embodiment, the lifting rod includes an integral threaded rod segment and a smooth rod segment, the smooth rod segment being used to pass through the pre-made hole; the lifting hole is provided on the smooth rod segment; the fixing member is screwed into the threaded rod segment.

[0012] Based on the above scheme, the lifting rod has a simple structure. By machining external threads on part of the outer circumference, the machining difficulty is reduced, machining efficiency is improved, and thus machining costs are saved. The smooth rod segment passes through the pre-drilled hole, which fits tightly with the pre-drilled hole, has a large contact area, and provides high stability and safety during lifting. The fixing component is screwed to the threaded rod segment, which is convenient to assemble, has a self-locking function, is not easy to fall off, and has high safety.

[0013] In an optional embodiment, a widening head is provided at the end of the smooth rod segment away from the threaded rod segment, the width of the widening head being greater than the diameter of the smooth rod segment, and the lifting hole is provided on the widening head.

[0014] Based on the above solution, by setting a widened head, the width of a certain part of the lifting rod is increased. The widened head can contact the top of the precast beam, preventing the lifting rod from falling off the precast beam from top to bottom. The lifting rod and the precast beam are firmly connected after being inserted and fitted.

[0015] In an optional embodiment, the widened head is configured as an arc-shaped head, the diameter of which is larger than the diameter of the smooth rod segment.

[0016] Based on the above solution, the arc-shaped head design can reduce stress concentration, and the connection between the widened head and the smooth rod segment is less prone to cracking, making it safe and reliable to use.

[0017] In an optional embodiment, the fastener is configured as a fixing nut.

[0018] Based on the above solution, the fixing nut has a simple structure, is easy to process and manufacture, and has low cost. Furthermore, the fixing nut is directly screwed onto the threaded rod segment, making assembly convenient. When force is applied to the fixing nut to make it rotate relative to the threaded rod segment, slippage is not easily prevented, saving time and effort.

[0019] In an optional embodiment, the fixing nut includes an integral threaded cylinder and a washer, and the fixing nut is provided with a threaded hole that passes through both the threaded cylinder and the washer, and the threaded hole is screwed and fixed to the threaded rod segment.

[0020] Based on the above scheme, when the fixing nut is screwed into the threaded rod section, the washer plate contacts the leveling component, making it less prone to slippage.

[0021] In an optional embodiment, the leveling component includes a first plate, a second plate, and a third plate connected end to end in sequence, with the first plate and the third plate arranged at an acute angle; both the first plate and the third plate are provided with assembly through holes, and the lifting rod passes through the assembly through holes of both the first plate and the third plate; the abutting inclined surface is provided on the surface of the first plate away from the third plate.

[0022] Based on the above scheme, the leveling component is set as a triangular structure, which has high stability, good stress resistance, is not easily deformed or damaged during use, has a long service life, and is highly safe to use.

[0023] In an optional embodiment, the surface of the third plate away from the second plate is in planar contact with the fixing member.

[0024] Based on the above scheme, the third plate and the fastener are in planar contact, with a large contact area and stable force.

[0025] In an optional embodiment, the T-beam hoisting and positioning device further includes an anti-slip pad, which fits against the abutting inclined surface, and the hoisting rod passes through the anti-slip pad. The anti-slip pad is used to contact the bottom inclined side of the precast beam.

[0026] Based on the above solution, the anti-slip pads are placed between the leveling components and the precast beams, which can prevent the leveling components from directly contacting the precast beams, thereby reducing the damage to the precast beams caused by the leveling components and making the hoisting process safer and more reliable.

[0027] Secondly, this utility model provides a T-beam hoisting system, the T-beam hoisting system comprising:

[0028] The lifting equipment, the cable, and the T-beam lifting and positioning device described in any of the foregoing embodiments are provided, wherein one end of the cable is connected to the lifting equipment, and the other end of the cable is connected to the lifting hole.

[0029] The beneficial effects of this utility model embodiment include, for example:

[0030] In summary, the T-beam hoisting and positioning device provided in this embodiment is used in conjunction with a precast beam to provide fulcrums for cable positioning on the precast beam. In use, four positioning devices are typically employed, meaning four positioning devices are installed on the same precast beam to be hoisted, forming four hoisting fulcrums on the precast beam, thus improving the stability and reliability of the hoisting process. When the positioning device is used with the precast beam, the hoisting rod is first inserted into a precast hole in the precast beam. Then, the leveling component is inserted onto the hoisting rod from one side of the bottom of the precast beam, and then connected to the hoisting rod using fasteners to prevent the leveling component from falling off. During hoisting, the cable is connected to the top of the hoisting rod extending from the top of the precast beam. During the hoisting process, the weight of the precast beam acts on multiple leveling components, which are supported by the fasteners. By inserting the lifting rod through the precast hole, the lifting rod and the precast beam are positioned together. This method is convenient to operate. The lifting rod is restricted by the precast hole and is not easy to shake. The lifting process is stable and reliable, and the lifting process is highly safe. Attached Figure Description

Detailed Implementation

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0040] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0041] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0042] In the description of this utility model, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product is usually placed during use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0043] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0044] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0045] In existing technologies, precast beam hoisting generally employs two methods. One method involves installing lifting rings on the top of the precast beam, connecting them to slings, and then using lifting equipment to lift the beam using the slings. The other method involves binding steel wire ropes to the precast beam, looping the ropes around it, and connecting them to tension cables, then using lifting equipment connected to the tension cables to lift the beam. The first method carries the risk of the lifting rings easily detaching from the precast beam. The second method carries the risk of the steel wire ropes coming into contact with the edges of the precast beam, potentially damaging those edges.

[0046] In view of this, the designers have provided a T-beam hoisting and positioning device, which can improve the safety and reliability of T-beam hoisting and is less likely to damage the beam.

[0047] Please refer to Figures 1-4 This embodiment provides a T-beam hoisting and positioning device for installation on a precast beam 001. The T-beam hoisting and positioning device includes a hoisting rod 100, a fixing member 200, and a leveling member 300. The hoisting rod 100 is provided with a hoisting hole; the leveling member 300 is provided with an abutment slope 311, and an assembly through hole 301 is provided on the abutment slope 311, through which the hoisting rod 100 passes; the fixing member 200 is fixedly connected to the hoisting rod 100, and the fixing member 200 and the hoisting hole are distributed on opposite sides of the leveling member 300. The hoisting rod 100 is used to pass through the precast hole on the precast beam 001. The hoisting hole and the abutment slope 311 are located on both sides of the precast beam 001, and the abutment slope 311 is used to contact the bottom inclined side of the precast beam 001.

[0048] As described above, the working principle of the T-beam hoisting and positioning device provided in this embodiment is as follows:

[0049] Please refer to Figure 5 In use, four positioning devices are generally employed in conjunction, meaning four positioning devices are installed on the same precast beam 001 to be hoisted, forming four hoisting fulcrums on the precast beam 001, thus improving the stability and reliability of the hoisting process. Correspondingly, four reserved holes are provided on the precast beam 001, roughly located at the four corners of the same rectangle. When the positioning devices are used in conjunction with the precast beam 001, the hoisting rod 100 is first inserted into the reserved hole on the precast beam 001, and then the leveling component 300 is inserted onto the hoisting rod 100 from one side of the bottom of the precast beam 001. Finally, the fixing component 200 is used to connect to the hoisting rod 100 to prevent the leveling component 300 from falling off the hoisting rod 100. During hoisting, the cable is connected to the top of the precast beam 001 extending from the hoisting rod 100. During lifting, the weight of the precast beam 001 acts on multiple leveling components 300, which are supported by the fixing components 200. The hoisting rod 100 is inserted into a precast hole, achieving proper positioning between the hoisting rod 100 and the precast beam 001. This method is convenient, and the hoisting rod 100 is restrained by the precast hole, preventing swaying. The hoisting process is stable, reliable, and highly safe.

[0050] It should be understood that in actual operation, the number of positioning devices is set as needed, and multiple reserved holes can also be set on the precast beam 001, ensuring that the positioning device can cooperate with one reserved hole. To improve construction flexibility, the number of reserved holes on the precast beam 001 can be greater than the number of positioning devices, and the positioning device can select the reserved hole at the corresponding position according to the needs. Using four positioning devices and four reserved holes in combination can improve the stability of the precast beam 001 during hoisting.

[0051] The following embodiments illustrate the details of the T-beam hoisting and positioning device provided in this application by way of example.

[0052] Please see Figure 1 and Figure 2 In this embodiment, optionally, the lifting rod 100 includes an integral threaded rod segment 110 and a smooth rod segment 120. The smooth rod segment 120 is used to pass through a pre-drilled hole; the lifting hole is provided on the smooth rod segment 120; the fixing member 200 is screwed into the threaded rod segment 110. The lifting rod 100 is made of an integral structure, which has high structural strength, is not easily damaged during use, and has high safety. Furthermore, it is suitable for mass production, reducing processing and manufacturing costs. To improve the rigidity of the lifting rod 100, it can be manufactured using carbon steel.

[0053] It is worth noting that the lifting rod 100 is a cylindrical rod. By machining external threads on part of the outer circumference of the lifting rod 100, the machining difficulty is reduced, the machining efficiency is improved, and thus the machining cost is saved. The smooth rod segment 120 passes through the pre-drilled hole, and the fit with the pre-drilled hole is tight, with a large contact area, resulting in high stability and safe and reliable lifting during hoisting. The fixing part 200 is screwed to the threaded rod segment 110, which is convenient to assemble, has a self-locking function, is not easy to fall off, and has high safety.

[0054] Optionally, a widened head 130 is provided at the end of the smooth rod segment 120 away from the threaded rod segment 110. The width of the widened head 130 is greater than the diameter of the smooth rod segment 120, and a lifting hole is provided on the widened head 130. The widened head 130 can be configured as an arc-shaped head, with a diameter greater than the diameter of the smooth rod segment 120. During manufacturing, the widened head 130 and the smooth rod segment 120 are integrally formed, resulting in high overall structural strength and a long service life.

[0055] It should be understood that by setting the widening head 130, the width of a portion of the lifting rod 100 is increased. When the lifting rod 100 is inserted into the precast hole, the widening head 130 is located above the precast beam 001. The widening head 130 can contact the top of the precast beam 001, preventing the lifting rod 100 from falling off the precast beam 001 from top to bottom. The lifting rod 100 and the precast beam 001 are firmly connected after being inserted and fitted.

[0056] In addition, the arc-shaped head design reduces stress concentration, and the connection between the widened head 130 and the smooth rod segment 120 is less prone to cracking, making it safe and reliable to use.

[0057] Please see Figure 1 and Figure 3 In this embodiment, optionally, the fixing member 200 is a fixing nut. The fixing nut has a simple structure, is easy to process and manufacture, and has low cost. Furthermore, the fixing nut is directly screwed into the threaded rod segment 110, making assembly convenient. When force is applied to the fixing nut to make it rotate relative to the threaded rod segment 110, it is not easy to slip, saving time and effort. It should be understood that the fixing nut is made of metal material, and only needs to meet the required rigidity.

[0058] Optionally, the fixing nut includes an integral threaded sleeve 210 and a washer 220. The fixing nut has a threaded hole that passes through both the threaded sleeve 210 and the washer 220, and the threaded hole is screwed to the threaded rod segment 110 for fixation. After the fixing nut and the threaded rod segment 110 are screwed together, the washer 220 contacts the leveling component 300, resulting in a large contact area, making it less prone to slippage and wear failure.

[0059] Please see Figure 1 and Figure 4 In this embodiment, optionally, the leveling component 300 includes a first plate 310, a second plate 320, and a third plate 330 connected end-to-end. The first plate 310 and the third plate 330 are set at an acute angle, the first plate 310 and the second plate 320 are set at an acute angle, and the second plate 320 and the third plate 330 are set at a right angle, so the leveling component 300 is approximately a right-angled triangle structure. Both the first plate 310 and the third plate 330 are provided with mounting through holes 301. The mounting through holes 301 on the first plate 310 and the second plate 320 are both circular holes and coaxially arranged, and the axial direction of the mounting through holes 301 is perpendicular to the surface of the third plate 330. The lifting rod 100 passes through the mounting through holes 301 of both the first plate 310 and the third plate 330. The abutment slope 311 is provided on the surface of the first plate 310 away from the third plate 330.

[0060] With this design, the leveling component 300 is set as a triangular structure, which has high stability, good stress distribution, is not easily deformed or damaged during use, has a long service life, and high safety. The lifting rod 100 passes through the assembly through hole 301 and is positioned with both the first plate 310 and the third plate 330. The lifting rod 100 is perpendicular to the third plate 330. The fixing component 200 is screwed onto the lifting rod 100. The fixing component 200 contacts the surface of the third plate 330 away from the first plate 310, and the two are in planar contact, with a large contact area, resulting in stable and reliable stress distribution.

[0061] In this embodiment, optionally, the T-beam hoisting and positioning device further includes an anti-slip pad 400, which fits against the abutting inclined surface 311. The hoisting rod 100 passes through the anti-slip pad 400, and the anti-slip pad 400 is used to contact the bottom inclined surface of the precast beam 001. It should be understood that the anti-slip pad 400 can be independent of the leveling component 300. In use, the anti-slip pad 400 is placed on the abutting inclined surface 311, and the hoisting rod 100 passes through the anti-slip pad 400 and then through the leveling component 300, thereby fixing the relative position of the anti-slip pad 400 and the leveling component 300. By designing the anti-slip pad 400 and the leveling component 300 separately, it is easy to replace the anti-slip pad 400. Alternatively, in some embodiments, the anti-slip pad 400 can be directly fixed to the abutting inclined surface 311 of the leveling component 300.

[0062] In actual use, the anti-slip pad 400 is placed between the leveling component 300 and the precast beam 001. The anti-slip pad 400 contacts the precast beam 001, which can prevent the leveling component 300 from directly contacting the precast beam 001, thereby reducing the damage of the leveling component 300 to the precast beam 001, and making the hoisting process safer and more reliable.

[0063] The T-beam hoisting and positioning device provided in this embodiment has at least the following advantages:

[0064] Traditional T-beam hoisting mostly employs lifting rings or beam-supporting techniques. Traditional methods can lead to ring breakage, causing the beam to fall. Supporting the beam can result in corner damage if corner guards are not installed, severely impacting the beam's appearance and potentially causing structural failure. This embodiment utilizes a 100-type lifting rod, significantly enhancing safety and stability during hoisting, offering substantial long-term benefits. Its ease of installation and disassembly also protects workers, greatly reducing labor intensity and the number of personnel required. Furthermore, it surpasses traditional techniques in terms of technology and uses simpler materials, resulting in significant long-term social benefits.

[0065] This embodiment also provides a T-beam hoisting system, which includes hoisting equipment, cables, and T-beam hoisting positioning devices. One end of the cable is connected to the hoisting equipment, and the other end is connected to the hoisting hole. It should be understood that the number of cables is consistent with the number of positioning devices. For example, when assembling four positioning devices on the precast beam 001, four cables are used to connect to the four positioning devices respectively, and then the other ends of the four cables are gathered and connected to the hoisting equipment.

[0066] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
