Description

Technical Field

[0001] The present invention belongs to the technical field of construction engineering construction, and specifically relates to an axis positioning structure for precast beam construction. Background Art

[0002] As a commonly used structural component in modern construction engineering, precast beams are widely used in the construction of bridges, high-rise buildings, industrial factories, etc. The installation process of precast beams includes precise measurement and lofting. First, determine the installation position of the beam body according to the design drawings to ensure that the dimensions and positions meet the requirements, prepare for hoisting, install appropriate lifting tools and check the capacity of the lifting equipment, use a crane to lift the beam body to the designated position, ensure accurate docking and install the precast beams one by one, ensure that the beam body is horizontal, fix it with supports after adjustment, and use connection methods such as steel bars, bolts or welding to fix the beam to the support structure to ensure firm and reliable connection, and conduct strength inspection.

[0003] For example, the utility model with the publication number CN222632510U discloses a precast beam installation structure, including precast columns. The number of the precast columns is two. A precast beam is arranged on the top of the precast columns. Installation mechanisms for quickly and firmly connecting two precast beams are arranged at both ends of the precast beam. A connection mechanism is arranged between the precast column and the precast beam. By setting the precast columns, precast beams, installation mechanisms and connection mechanisms, the installation mechanisms can enable quick and firm connection between multiple groups of precast beams during the construction of precast beams, enhance the connection strength between two groups of precast beams, improve the installation efficiency and installation strength of precast beams, and the connection mechanisms can enable quick and firm installation between the precast beam and the precast column, improving the stability of precast beam installation.

[0004] During the construction process of precast beams, when the crane lifts the beam body to the designated position, it needs to be accurately placed on the top of the installation column for welding and fixing. Due to the differences in the sizes of existing precast beams and the possible deviations between the sizes of the installation columns and the design requirements, the axis of the precast beam may deviate from the installation column during the placement process. The deviation will not only affect the docking accuracy between the beam body and the support column, but also may cause the beam body to be unable to correctly align with the design position, thereby affecting the stability and structural safety of the beam body. In addition, the size differences between the precast beam and the installation column may also cause additional adjustment work during installation. For example, the beam body may need to be adjusted multiple times to ensure its precise placement, increasing the complexity and construction period of the construction. The deviation of the beam body may cause difficulties in subsequent welding and fixing operations. More compensatory operations may be required during the welding process, resulting in a delay in the overall construction progress.

[0005] Therefore, an axis positioning structure for precast beam construction is proposed to solve the problems raised in the background art. Summary of the Invention

Detailed implementation manners

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] As Figures 1 to 8 shown, the present invention provides a construction axis positioning structure for precast beams, including;

[0037] Support columns 1, at least two are provided, and the two support columns 1 are arranged in the same horizontal direction;

[0038] Precast beam 01, arranged above the support column 1;

[0039] Installation component 100, arranged on the outer wall of the support column 1, and an installation mechanism is arranged on the outer wall;

[0040] Positioning component 200, slidably installed on the top of the installation component 100;

[0041] Transmission component 300, fixedly installed on the top of the positioning component 200;

[0042] Among them, the transmission component 300 includes a power component and a transmission component. There are two groups of transmission components and they are symmetrically distributed. The transmission component includes a mounting block 31. A second rotating rod 32 and a third rotating rod 33 are rotatably mounted on the inner wall of the mounting block 31. A first half gear 322 and a second half gear 331 are respectively and fixedly sleeved on the outer walls of the second rotating rod 32 and the third rotating rod 33. The first half gear 322 meshes with the second half gear 331. A first connecting rod 323 and a third connecting rod 332 are respectively and fixedly sleeved on the outer walls of the second rotating rod 32 and the third rotating rod 33. A second connecting rod 3231 and a fourth connecting rod 3321 are respectively and hingedly mounted on the outer walls of the first connecting rod 323 and the third connecting rod 332. The other ends of the second connecting rod 3231 and the fourth connecting rod 3321 are both hingedly mounted on a positioning plate 4. The top of the positioning plate 4 is bent outwards and is designed as an obtuse angle. The power component includes a double-headed motor 22. A worm 221 is respectively and fixedly mounted on the two output shafts of the double-headed motor 22. A half worm gear 321 is fixedly sleeved on the outer wall of the second rotating rod 32. The half worm gear 321 meshes with the corresponding worm 221. The positioning component 200 includes a support plate 21. The support plate 21 is fixedly connected to the mounting block 31 and the double-headed motor 22. Two fixing blocks 212 are fixedly mounted on the top of the support plate 21. The two fixing blocks 212 are respectively and rotatably connected to the corresponding worms 221.

[0043] Adopting the above scheme: The support columns 1 are arranged in at least two in the same horizontal direction for supporting the precast beam 01. On the basis of the support columns 1, the stability of the precast beam 01 is ensured, and it can effectively bear the weight of the precast beam 01 and ensure its accurate position. The precast beam 01 is supported by the support columns 1 to ensure that the beam body is stably placed at the designed position. The stable installation of the precast beam 01 is an important part of the construction process to avoid structural problems caused by inaccurate position of the beam body. The installation component 100 is arranged on the outer wall of the support column 1 and provides an installation platform for the positioning component 200. The setting of the installation mechanism can ensure the stable installation and adjustment of the positioning component 200 and improve the construction accuracy. The positioning component 200 is slidably mounted on the top of the installation component 100, which enables the positioning component 200 to be accurately adjusted on the axis to ensure the accurate alignment of the precast beam 01. The sliding design allows the positioning component 200 to be freely adjusted to adapt to the construction requirements of different precast beam 01 sizes.

[0044] The transmission component 300 includes a power component and a transmission component, which are divided into two groups with a symmetrical design. The transmission component 300 ensures that the positioning plate 4 can be positioned according to the control requirements and is driven and adjusted through power transmission. The power component includes a double-headed motor 22. Worms 221 are respectively and fixedly mounted on the two output shafts of the motor. The double-headed motor 22 drives the worms 221 to mesh with the half worm gears 321, thereby driving the second rotating rod 32 and the third rotating rod 33 by rotating the worm gears. In this way, the double-headed motor 22 can effectively control the movement of the positioning plate 4.

[0045] Rotating rods are respectively rotatably installed on the inner walls of the second rotating rod 32 and the third rotating rod 33 in the transmission assembly, and a first half gear 322 and a second half gear 331 are installed on the outer walls of the rotating rods to control the movement of the positioning plate 4, ensuring that the positioning assembly 200 can quickly and accurately align with the position of the precast beam 01;

[0046] Through the first connecting rod 323, the third connecting rod 332, the second connecting rod 3231 and the fourth connecting rod 3321, a connecting rod drive is formed. Each connecting rod is connected to the positioning plate 4 by a hinge, ensuring that the positioning plate 4 always moves stably and synchronously during the movement. Driven by the transmission assembly, the positioning plate 4 can adjust the distance as needed to ensure the accuracy of the axis of the precast beam 01;

[0047] By bending the top of the positioning plate 4 outward and designing it to be obtuse, it makes it easier for the precast beam 01 to enter the middle of the two positioning plates 4, strengthening the fixing effect on the precast beam 01;

[0048] By adopting symmetrically distributed transmission assemblies and a double-headed motor 22, and driving the movement of each component synchronously through the double-headed motor 22, the position of the positioning plate 4 is accurately controlled to ensure that the precast beam 01 remains in the accurate position during the installation process and avoid errors.

[0049] As Figures 1 to 8 shown, two second bumps 211 are fixedly installed at the bottom of the support plate 21, and the two second bumps 211 are designed in a plum blossom shape; the installation mechanism includes a first clamping block 11 and a second clamping block 12 slidably installed on the outer walls of the two second bumps 211. Chutes 13 are respectively opened at the tops of the first clamping block 11 and the second clamping block 12. The chutes 13 are adapted to and slidably connected to the second bumps 211; two screw rods 111 are rotatably installed on the outer wall of the first clamping block 11, and both of the two screw rods 111 penetrate through the second clamping block 12 and are threadedly connected to the second clamping block 12; two slide rails 112 are fixedly installed at the bottom of the first clamping block 11, and two first bumps 121 are fixedly installed at the bottom of the second clamping block 12. The two first bumps 121 are respectively slidably connected to the corresponding slide rails 112; a rectangular groove is opened on one outer wall of the support plate 21, and the area value of the rectangular groove is larger than the top area value of the support column 1.

[0050] Adopting the above solution: The plum blossom design of the second bump 211 helps to improve the structural stability, can evenly distribute the load, avoid excessive local pressure, and enhance the overall bearing capacity; it can also make the first clamping block 11 and the second clamping block 12 be more firmly fixed on the support plate 21; through the matching design of the sliding grooves 13 respectively opened at the tops of the first clamping block 11 and the second clamping block 12 with the second bump 211, the first clamping block 11 and the second clamping block 12 can slide smoothly and without resistance, ensuring their precise docking, thereby improving the placement accuracy of the precast beam 01; the slide rail 112 installed at the bottom of the first clamping block 11 is slidably connected with the first bump 121 at the bottom of the second clamping block 12, ensuring that the second clamping block 12 can slide smoothly and precisely along the slide rail 112; this not only improves the flexibility of the structure, but also can conveniently adjust the distance between the clamping blocks to adapt to precast beams 01 of different sizes; through the threaded connection between the screw 111 and the second clamping block 12, it can be ensured that the second clamping block 12 will not loosen during the adjustment process, providing higher stability and reliability, and avoiding structural instability caused by the loosening of the threaded connection; the second bump 211 at the bottom of the support plate 21 and the sliding installation structure of the first clamping block 11 and the second clamping block 12 reduce the complex operations in the traditional installation method, making the installation process simpler and more efficient; at the same time, it becomes easier to adjust the position of the clamping blocks, and the construction personnel can quickly complete the fixation of the beam body, saving time and improving work efficiency; the rectangular groove opened on the outer wall of one side of the support plate 21 has an area value larger than the area value of the top of the support column 1, which enables the support plate 21 to flexibly adapt to support columns of different specifications and provides a large adjustment space, helping to adapt to different installation requirements; the design of the installation mechanism is compact, the structure is simple and integrated, and through combinations such as threads, slide rails 112, and first bumps 121, an efficient installation mechanism is formed; the close cooperation of each component reduces the volume of the equipment, reduces the occupied space, and also makes the operation more convenient.

[0051] The working principle and usage process of the present invention:

[0052] The construction personnel first rotate the screw 111. Due to the threaded connection between the second clamping block 12 and the screw 111, when the screw 111 rotates, the second clamping block 12 can drive the first bump 121 at the bottom to move linearly in the slide rail 112, making the second clamping block 12 move away from the first clamping block 11, and then slide it into the outer wall of the support column 1. After determining the position, reverse-rotate the screw 111, making the second clamping block 12 approach the first clamping block 11 and finally fix it on the outer wall of the support column 1;

[0053] Then align the second bump 211 at the bottom of the support plate 21 with the sliding grooves 13 at the tops of the first clamping block 11 and the second clamping block 12 and slide it in. When the support plate 21 is installed;

[0054] Start the double-headed motor 22, so that the output shaft of the double-headed motor 22 drives the worm 221 to rotate. Through the meshing of the worm 221 and the half worm wheel 321, the half worm wheel 321 is driven to drive the second rotating rod 32 to rotate. The second rotating rod 32 drives the first half gear 322 to rotate. Through the meshing of the first half gear 322 and the second half gear 331, the second half gear 331 is driven to rotate. The second half gear 331 drives the third rotating rod 33 to rotate;

[0055] Then, the first connecting rod 323 and the second connecting rod 3231 are driven to move by the second rotating rod 32, and the third connecting rod 332 and the fourth connecting rod 3321 are driven to move by the third rotating rod 33. Since the rotation directions of the second rotating rod 32 and the third rotating rod 33 are opposite, and the second connecting rod 3231 and the fourth connecting rod 3321 are hinged to the positioning plate 4, the two positioning plates 4 are driven to move horizontally closer to and away from each other; The distance between the two positioning plates 4 is adjusted according to the width value of the precast beam 01, so that the precast beam 01 can be accurately placed on the top of the support column 1.
