Description

Technical Field

[0001] The utility model belongs to the technical field of assembled buildings, and in particular relates to a positioning tool for pre-embedded steel bars of PC components. Background Art

[0002] With the rapid development of society and the continuous rise in labor costs, the construction industry is moving towards high integration and industrialization. At the same time, the production methods of building materials are also gradually transforming. Factoryization and prefabrication have become new trends, promoting the widespread application of prefabricated and modular building technologies. Prefabricated buildings prefabricate all the PC components required for residential buildings on factory assembly lines and then transport them to the construction site for hoisting and splicing. With its advantages of convenient construction, fast speed and strong adaptability to the building environment, it occupies an important position in the field of modern construction.

[0003] However, in prefabricated buildings, the production process of embedded steel parts still faces some challenges. The production of embedded steel parts involves multiple links such as cutting, assembly, welding, and packaging, among which the assembly process is particularly complex and time-consuming. Due to the importance of steel bar positioning during the assembly process, once the positioning is wrong, the embedded parts will be scrapped, resulting in a waste of resources. The traditional assembly method relies on manual positioning and marking, and then the riveters perform spot welding and fixation according to the markings. This method is not only time-consuming, but also prone to errors. During the spot welding process, the various parts of the embedded parts may also slide, resulting in position deviation, further increasing the risk of inaccurate positioning.

[0004] Therefore, in order to improve the production efficiency and accuracy of embedded steel parts and reduce production costs and waste, it is necessary to introduce new technologies and methods to optimize the assembly process of embedded steel parts. This will help promote the further development of prefabricated building technology and meet the needs of modern buildings for high integration and high efficiency. Utility Model Content

[0005] Aiming at the problem of inaccurate positioning often occurring in the assembly process during the production of pre-embedded steel bars of PC components, the utility model provides a positioning tool for pre-embedded steel bars of PC components.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a positioning tool for embedded steel bars of PC components, comprising a base plate, a support frame is arranged at the bottom of the base plate, an end baffle and at least two positioning plates are vertically arranged on the top of the base plate, a side baffle is arranged at one end of the end baffle, and a plurality of grooves are arranged side by side on each of the positioning plates in a comb shape, which are located between the same longitudinal grooves of the two positioning plates and are used for embedding and installing longitudinal main bars, and a plurality of groups of positioning plates are arranged on the base plate, each group of positioning plates includes at least two and is used for embedding and installing transverse main bars.

[0007] As a further supplement to the above technical solution, a plurality of vertical baffles are arranged on the inner side of the end baffle, and the limiting groove formed between two adjacent vertical baffles corresponds to the groove of the positioning plate, which is used to cooperate with the positioning plate to jointly limit the swing of the longitudinal main reinforcement.

[0008] As a further supplement to the above technical solution, reinforcing ribs are respectively provided at both ends of each positioning plate to enhance the connection strength with the base plate, and the reinforcing ribs are used to prevent the connection structure of the positioning plate from being deformed.

[0009] As a further supplement to the above technical solution, a diagonal support plate is provided on the outer side of the end baffle to enhance the connection strength with the bottom plate, and the diagonal support plate is used to prevent the connection structure of the end baffle from being deformed.

[0010] As a further supplement to the above technical solution, a group of screw holes are set on the base plate between the end baffle and the positioning plate, and at least two groups of screw holes are set on the base plate between the two positioning plates, and the positioning plate is installed in the screw holes by bolts.

[0011] As a further explanation and limitation of the above technical solution, the positioning plate includes a fixed base plate and a support plate arranged perpendicularly thereto, the support plate is provided with an embedding groove for embedding and installing the transverse main reinforcement, and the fixed base plate is provided with a strip slot hole for passing the bolt.

[0012] As a further supplement to the above technical solution, a handle is provided on the end baffle to facilitate movement of on-site personnel.

[0013] Compared with the prior art, the utility model has the following advantages:

[0014] 1. The utility model can accurately position the longitudinal main reinforcement and the transverse main reinforcement at the predetermined position by designing a comb-shaped slotted positioning plate, combined with the installation method of the positioning plate and the screw hole. The precise positioning and stable structure reduce the workload of manual marking and positioning, reduce the difficulty of operation and human errors, and thus improve work efficiency and safety. At the same time, by adding a vertical baffle, the positioning accuracy and stability of the longitudinal main reinforcement are further enhanced, the swing of the steel bar during the assembly process is avoided, and the assembly quality of the PC component is ensured.

[0015] 2. The utility model significantly enhances the connection strength between the positioning plate and the base plate, and between the end baffle and the base plate through the design of the reinforcing rib plate and the diagonal support plate, making the entire tooling structure more stable, able to withstand greater external forces, and effectively preventing deformation and damage of the tooling during use.

[0016] 3. The handle design of the utility model enables on-site personnel to easily move and carry the entire tooling, thereby improving work efficiency. At the same time, the handle can also be used as a fixing point to facilitate fixing the tooling at the desired position, further improving the flexibility and convenience of operation.

[0017] 4. The positioning tooling for embedded steel bars of PC components provided by the utility model has the advantages of high precision, high stability, strong structure, easy operation and low scrap rate, which avoids the scrapping of PC components and waste of resources due to inaccurate positioning or loose assembly. At the same time, by improving the assembly accuracy and stability, it can also reduce the cost of later maintenance and replacement, which is of great significance to improving the assembly quality and efficiency of PC components.

[0026] Furthermore, in the above embodiment, the positioning plate 6 includes a fixed base plate 601 and a support plate 602 arranged perpendicularly thereto, and an embedding groove 603 is provided on the support plate 602 for embedding and installing the transverse main reinforcement 14, and a strip slot hole 604 is provided on the fixed base plate 601 for passing the bolt 7. Embodiment 2

[0027] On the basis of the first embodiment, in order to further improve the positioning accuracy and stability of the longitudinal main reinforcement. Figure 2 As shown, in this embodiment, a plurality of vertical baffles 9 are added to the inner side of the end baffle 4. These vertical baffles 9 are parallel to the positioning plate 3, and the limiting groove formed between two adjacent vertical baffles 9 corresponds to the slot of the positioning plate 3. When the longitudinal main rib 13 is embedded in the slot of the positioning plate 3, it will also enter the limiting groove formed by the adjacent vertical baffle 9, thereby forming a double limiting system together with the positioning plate 3, effectively preventing the longitudinal main rib 13 from swinging during the assembly process, and further improving the positioning accuracy and stability.
