Description

Technical Field

[0001] This utility model belongs to the field of building construction, and in particular relates to groove-type embedded parts for prefabricated buildings. Background Technology

[0002] Embedded parts are metal connectors pre-embedded in concrete components, primarily used for the splicing and fixing of prefabricated components in prefabricated buildings. Functionally, they can be divided into structural embedded parts and non-structural embedded parts: the former, such as shear wall connection plates and beam-column joint steel plates, bear the main load transfer; the latter, such as curtain wall supports and equipment installation bases, serve the building's auxiliary functions. Material selection must balance strength and durability, commonly using Q235B or Q355B steel, with surface treatment of hot-dip galvanizing or epoxy coating for corrosion prevention. The design must comply with the "Technical Specification for Prefabricated Concrete Structures," using BIM technology to accurately locate the embedded positions, avoiding conflicts with reinforcing steel, and conducting pull-out force tests to verify anchorage performance. Embedded parts for prefabricated buildings are an important component of modern industrialized construction; their design and application directly affect the stability of the building structure and construction efficiency.

[0003] Comparing with Chinese Patent No. CN222822537U, a prefabricated building embedded component is disclosed, including an assembly and an embedded component. The assembly includes an expansion tube with several openings at equal angles on one end of its sidewall. A frustum-shaped section is located at one end of the expansion tube, close to the openings. A screw is attached to one end of the frustum-shaped section, extending into the interior of the expansion tube. A crossbar is fixedly connected inside the expansion tube, and the screw is threaded into and connected to the crossbar. A threaded section is provided on the inner wall of the other end of the expansion tube. The embedded component includes a fixing plate with a connecting pipe fixedly connected to its center. One end of the connecting pipe is an arc segment, and the expansion tube fits inside the connecting pipe. A cover is fastened to the end of the arc segment. The assembly and embedded component facilitate the construction of the embedded component and the connection to external components.

[0004] However, the aforementioned patented expansion plug-in fixation has a limited adjustment range, which increases the difficulty of assembly and adjustment, and greatly limits the scenarios in prefabricated buildings where repeated adjustments to the connection are required. Therefore, a new device needs to be designed. Utility Model Content

[0005] The purpose of this utility model is to provide a grooved embedded part for prefabricated buildings to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A prefabricated channel-type embedded component for prefabricated buildings includes a base assembly for fixing threaded steel bars in series, and a box-type channel assembly for support and adjustment fixedly installed on the base assembly. An adjustment component for adjustment and connection is installed in the middle of the box-type channel assembly. The base assembly includes a base plate with four ear plates evenly distributed at its four corners. A through hole is provided in the middle of each ear plate, through which the threaded steel bar passes. The box-type channel assembly includes a box-type channel body, which is rectangular in shape. A limit groove is provided at the top of the box-type channel body, and anti-slip teeth are provided on the inner top surface of the box-type channel body. Two plug mechanisms are symmetrically installed at both ends of the box-type channel body. The adjustment component includes an adjustment screw, a connecting plate fixedly installed at the top of the adjustment screw, a locking nut installed in the middle of the adjustment screw, and a limit block at the bottom of the adjustment screw.

[0008] Furthermore, several anchor legs are evenly distributed on both sides of the base plate, and the bottom end of each anchor leg is provided with an anti-detachment flange.

[0009] Furthermore, the anti-detachment edge is circular.

[0010] Furthermore, both the base plate and the anchor leg are made of Q235 material, and the anchor leg has a diameter of φ12mm and a length of 80mm-120mm.

[0011] Furthermore: the plug mechanism includes a cover, and the side of the cover is provided with a plug platform.

[0012] Furthermore, the tank body is made of Q355B galvanized material or 316L stainless steel.

[0013] Furthermore: the limiting block uses an M20 square nut, the locking nut uses an M20 hexagonal nut, and the connecting plate and the adjusting screw are welded together.

[0014] Compared with existing technologies, the beneficial effects are:

[0015] 1. Through the triple design of stable anchoring, flexible adjustment and efficient assembly, the pre-embedded pouring is completed first, and then the assembly position is adjusted independently, which reduces the interference of cross-operations on site and reduces the complexity of construction; it solves the problems of inaccurate positioning and difficult adjustment of traditional pre-embedded parts, and is especially suitable for scenarios in prefabricated buildings where repeated adjustments to the connection are required, combining construction convenience, economy and long-term reliability.

[0016] 2. The limiting block moves freely through the slide groove, facilitating quick adjustment of the connecting plate position; the anti-slip teeth provide friction locking to prevent accidental slippage during construction and ensure positioning accuracy; the limiting block can be tightened by tightening the locking nut to achieve quick fixation without complicated tools, greatly improving assembly efficiency; the position of the connecting plate can be steplessly adjusted along the slide groove to adapt to the installation requirements of different assembly components and enhance the versatility of embedded parts.

[0017] 3. By using the ear plate through-hole design at the four corners of the base plate and the pre-embedded threaded steel bars in series, combined with the evenly distributed anchor legs (with anti-detachment flanges), the pull-out resistance and stability of the embedded parts in the concrete are significantly enhanced, preventing displacement or detachment during pouring; the circular anti-detachment flanges further increase the contact area between the anchor legs and the concrete, improve the fixing force, and ensure long-term load-bearing reliability.
