Abstract
Description
Technical Field
[0001] This utility model belongs to the field of building embedded parts technology, and more specifically, it relates to a prefabricated building embedded part. Background Technology
[0002] Prefabricated buildings refer to buildings where a large amount of on-site work in traditional construction methods is transferred to factories. Building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in factories, transported to the construction site, and assembled on-site using reliable connection methods. Embedded parts (prefabricated embedded parts) are components that are pre-installed (embedded) in concealed works. They are components that are placed during the pouring of the structure and are used for overlapping when building the superstructure to facilitate the installation and fixing of external engineering equipment foundations.
[0003] Existing pre-embedded components for prefabricated buildings still have the following shortcomings:
[0004] One issue is that there is room for improvement in the contact efficiency between the embedded parts and the concrete. When the contact efficiency between the embedded parts and the poured concrete is too low, it is easy for the embedded parts to tip over or detach from the concrete. Another issue is that after the embedded parts are connected by fixing screws, the fixing screws are likely to loosen under the influence of the external environment during subsequent use. Utility Model Content
[0005] To address the aforementioned technical problems, this utility model provides a prefabricated building embedded component. One issue is that the contact efficiency between the embedded component and the concrete has room for improvement; when the contact efficiency is too low, it can easily lead to tipping over or the embedded component detaching from the concrete. Another issue is that after the embedded component is connected by fixing screws, the fixing screws are prone to loosening under the influence of the external environment during subsequent use.
[0006] The purpose and function of this utility model for a prefabricated building embedded component are achieved by the following specific technical means:
[0007] An embedded component for prefabricated buildings includes a main block; the main block is a rectangular block structure, and a first connecting rod is welded in a rectangular array on the bottom surface of the main block. The first connecting rod is a cylindrical rod structure, and the lower end of each of the rectangular array of first connecting rods is welded to a base.
[0008] Furthermore, four auxiliary seats are welded to the top surface of the base. Each of the four auxiliary seats is an L-shaped block structure, and the inner side of each of the four auxiliary seats is welded to the main block.
[0009] Furthermore, a casting hole is provided at the center of the top surface of both the main block and the base, and the casting hole is a circular hole structure.
[0010] Furthermore, four ground nails are welded to the bottom end face of the base, and four auxiliary blocks are welded in a circular array on the outer wall of each ground nail. All sixteen auxiliary blocks are rectangular block-shaped joint structures.
[0011] Furthermore, each of the auxiliary blocks has two symmetrically formed grooves, which are rectangular grooves.
[0012] Furthermore, four square tubular connecting seats are welded to the top surface of the main body block. A second connecting rod with a square tubular structure is inserted into each connecting seat. A fixing screw for fixing the second connecting rod is threaded onto each connecting seat. Two anti-loosening blocks are welded onto each main body block. All eight anti-loosening blocks are rectangular block structures. The inner sides of the two anti-loosening blocks on each connecting seat are in close contact with the outer wall of the fixing screw adjustment point.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] Significantly improves the stability of the pouring: During the cement pouring operation, the cement can fully flow into the gap between the main block and the base, greatly increasing the contact area between the cement and the main block and the base; this design greatly improves the stability after pouring, making the entire structure more stable when subjected to external forces, and effectively reducing the risk of structural deformation or damage due to weak connection.
[0015] Significantly enhanced connection strength: Four L-shaped auxiliary seats are welded to the top surface of the base, and the inner sides of these four auxiliary seats are tightly welded to the main body block. During actual use, these auxiliary seats play a crucial supporting and reinforcing role, significantly improving the connection strength between the main body block and the base. This not only makes the overall structure more robust but also enhances its safety in various complex environments, effectively preventing loosening or separation between the main body block and the base, and extending the structure's service life.
[0016] Effectively improves pouring efficiency: By operating through this pouring hole, concrete can flow more smoothly and quickly into the part that needs to be filled, avoiding problems such as uneven pouring and the need to adjust the pouring position multiple times that may occur with traditional pouring methods. This greatly improves pouring efficiency, saves construction time and labor costs, and also helps to ensure the quality and uniformity of concrete pouring.
[0017] Significantly improves adhesion: After the concrete is poured, the concrete will come into full contact with the auxiliary block. The presence of the auxiliary block significantly increases the contact area and friction between the structure and the concrete, which greatly improves the adhesion between the two. This effectively reduces the probability of the device detaching from the concrete, ensures the stability of the structure in the concrete foundation, and provides a strong guarantee for the safety of the entire structure.
[0018] To maximize contact area: Each auxiliary block has two symmetrical rectangular grooves; these grooves further increase the contact area between the auxiliary block and the cement. More contact area means greater adhesion, allowing the auxiliary block to bond more tightly to the cement, thus enhancing the anchoring effect of the auxiliary block in the concrete and further improving the safety and stability of the overall structure, enabling it to better resist various external forces.
[0019] To effectively prevent screw loosening: Four square tubular connecting seats are welded to the top surface of the main body block. Each connecting seat contains a square tubular second connecting rod, which is fixed by a threaded fixing screw. Simultaneously, two rectangular anti-loosening blocks are welded to each main body block. The inner sides of the two anti-loosening blocks on each connecting seat are in close contact with the outer wall of the fixing screw adjustment area. When the fixing screw is tightened, the anti-loosening blocks exert a continuous counterforce on the fixing screw, effectively preventing loosening due to external vibrations, structural deformation, or other factors. This ensures that the connection between the second connecting rod and the connecting seat remains secure, improving the safety and reliability of the overall structure during use.

[0030] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.
[0031] Example 1:
[0032] As attached Figure 1 To be continued Figure 6 As shown:
[0033] This utility model provides a prefabricated building embedded component, including a main block 1. The main block 1 is a rectangular block structure, and a first connecting rod 101 is welded in a rectangular array on the bottom surface of the main block 1. The first connecting rod 101 is a cylindrical rod structure. The lower end of each of the rectangular array of first connecting rods 101 is welded to a base 102. After the main block 1, the first connecting rod 101 and the base 102 are embedded in the soil, cement needs to be poured. When the cement enters between the main block 1 and the base 102, it can increase the contact area between the cement and the main block 1 and the base 102, thereby improving the stability after pouring.
[0034] The base 102 has four auxiliary seats 103 welded to its top surface. Each of the four auxiliary seats 103 is an L-shaped block structure. The inner sides of the four auxiliary seats 103 are welded to the main body block 1. During use, the welding of the four auxiliary seats 103 can improve the connection strength between the main body block 1 and the base 102, thereby improving the overall safety.
[0035] Both the main block 1 and the base 102 have a pouring hole 104 at the center of their top surfaces. The pouring hole 104 is a circular hole structure. During use, concrete can be poured through the pouring hole 104, which can improve the pouring efficiency.
[0036] The base 102 has four ground nails 201 welded to its bottom surface. Each ground nail 201 has four auxiliary blocks 202 welded in a ring array on its outer wall. All sixteen auxiliary blocks 202 are rectangular block joint structures. After the concrete is poured, the concrete will come into contact with the auxiliary blocks 202, which can improve the adhesion between the structure and the concrete, reduce the probability of the device detaching from the concrete, and improve safety.
[0037] Each auxiliary block 202 has two symmetrical grooves 203. The grooves 203 are rectangular grooves. During use, the grooves 203 can increase the contact area between the auxiliary block 202 and the cement, thereby improving the stability of the adhesion between the auxiliary block 202 and the cement, and thus improving the overall safety.
[0038] Example 2:
[0039] Based on Embodiment 1, four square tubular connecting seats 301 are welded to the top surface of the main body block 1. A square tubular second connecting rod 302 is inserted into each connecting seat 301. A fixing screw 303 for fixing the second connecting rod 302 is threaded onto each connecting seat 301. Two anti-loosening blocks 304 are welded onto each main body block 1. All eight anti-loosening blocks 304 are rectangular block structures. The inner sides of the two anti-loosening blocks 304 on each connecting seat 301 are in close contact with the outer wall of the adjustment point of the fixing screw 303. After the fixing screw 303 is tightened, the anti-loosening blocks 304 can reduce the probability of the fixing screw 303 loosening by pressing against the fixing screw 303, thereby improving the overall safety.
[0040] Working principle: During installation, insert four second connecting rods 302 into four connecting seats 301, and then thread a fixing screw 303 onto each connecting seat 301 and tighten it. After the fixing screw 303 is tightened, the four second connecting rods 302 can be fixed. First, dig a pre-embedded pit, place this device in the pre-embedded pit, and then add concrete through the pouring hole 104.
