Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of concrete embedded parts, and particularly relates to a concrete embedded part. Background Technology
[0002] Embedded parts (precast embedded parts) are steel reinforcement components that are pre-installed (embedded) in a structure. Existing concrete embedded parts use threaded steel bars. During use, the concrete embedded part is first tied together with the connecting frame, and then concrete is poured. These embedded parts mainly rely on the threads on the surface of the threaded steel bar to increase the contact area between the steel reinforcement and the concrete, working together with the concrete to share the load, thereby enhancing the bond and friction between them, ultimately increasing the strength of the concrete.
[0003] However, relying solely on the threads on the surface of the rebar to enhance the strength of concrete has limited effect and often fails to achieve significant results. Utility Model Content

The main reinforcing steel bars include a third support end, and the reinforcing steel section is connected to the first connection end and / or the second connection end through the third support end. The multiple sets of reinforcing components are arranged sequentially along the length direction of the main reinforcing steel bars in such a way that their axes coincide with the axis of the main reinforcing steel bars.
[0010] Furthermore, the reinforcing component includes multiple side bars, each side bar having a fourth support end.

[0029] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0030] like Figure 1-4 As shown, this utility model provides a concrete embedded part, such as... Figure 1 As shown, it includes a screw section 1 and at least one reinforcing bar section 2. The screw section 1 includes a main screw 11 and a plurality of auxiliary screws 12. The main screw 11 includes a first support end 111 and a first connecting end 112. The main screw 11 can be fixed to a connecting frame for supporting concrete embedded parts through the first support end 111. The plurality of auxiliary screws 12 are arranged at intervals along the length direction of the main screw 11 with their axes intersecting the axis of the main screw 11. The auxiliary screws 12 include a second support end 121 and a second connecting end 122 for connecting with the main screw 11.
[0031] The threads on the main screw 11, as well as the threads on the multiple auxiliary screws 12, increase the contact area between the concrete embedded part and the concrete, thereby enhancing the strength of the concrete. Simultaneously, the auxiliary screws 12 better prevent the main screw 11 from moving.
[0032] like Figure 2As shown, the reinforcing bar section 2 includes a main reinforcing bar 21 and multiple sets of reinforcing components 23. The main reinforcing bar 21 includes a third support end 211. The reinforcing bar section 2 is connected to the first connecting end 112 of the main screw 11 and / or the second connecting end 122 of the auxiliary screw 12 via the third support end 211. The multiple sets of reinforcing components 23 are arranged sequentially along the length direction of the main reinforcing bar 21 with their axes coinciding with the axis of the main reinforcing bar 21. The reinforcing components 23 include multiple side bars 231, each side bar 231 including a fourth support end 2311. The multiple side bars 231 are arranged along the same circumference on the side wall of the main reinforcing bar 21, and the side bars 231 are fixed to the side wall of the main reinforcing bar 21 via the fourth support end 2311.
[0033] The side reinforcement 231 also increases the contact area between the concrete embedded part and the concrete, thereby enhancing the strength of the concrete. At the same time, the side reinforcement 231 can better prevent the main reinforcement 21 from moving.
[0034] In order to further increase the contact area between the concrete embedded parts and the concrete and to increase the tensile strength inside the concrete, a first bend 22 is provided at the end of the main reinforcing bar 21 away from the third support end 211, and a second bend 233 is provided at the end of the side reinforcing bar 231 away from the fourth support end 2311.
[0035] The auxiliary screw 12 and the side reinforcement 231 together enhance the stability of the concrete embedded part.
[0036] In order to ensure that the fractured parts are evenly distributed in the concrete and that the deformation resistance of each area in the concrete is as similar as possible, multiple sets of reinforcing components 23 on the same main steel bar 21 are arranged at equal intervals.
[0037] The reinforcing bar 2 also includes a fracture section, which can break during concrete pouring to form multiple dispersed fibers within the poured concrete, thereby improving the concrete's resistance to deformation, as well as its toughness and impact resistance, enabling the concrete to better resist damage under impact loads. In this embodiment, as... Figure 2-3 As shown, each side reinforcement 231 is provided with multiple fibers 232 forming fracture sections, and the multiple fibers 232 are arranged in multiple rows along the circumferential direction on the side wall of the side reinforcement 231. This makes the concrete fiber-reinforced concrete. Due to the high tensile strength and elongation of the fibers, the tensile, flexural, and impact strength, as well as the elongation and toughness of the concrete are improved. The fibers can control the further development of cracks in the matrix concrete, thereby improving crack resistance. Simultaneously, as... Figure 4 As shown, the fiber 232 has multiple cracks 2321. When the fiber 232 is subjected to external force, the cracks 2321 will break, causing the fiber 232 to disperse into multiple dispersed fibers, thereby further playing the role of crack prevention. That is, it can prevent the expansion of existing defects in concrete such as microcracks, effectively delay the appearance of new cracks, and enhance impact resistance and tensile strength.
[0038] Preferably, the fiber 232 is spiral-shaped, which can increase its contact area with the hardened concrete, thereby improving the tensile strength of the concrete.
[0039] In order to enable the screw part 1 and the reinforcing bar part 2 to continuously play a role in enhancing strength in concrete, a carburizing protective layer is coated on the surface of the screw part 1 and the reinforcing bar part 2. The carburizing protective layer is a coating formed by non-ferrous metal or a coating formed by carburizing paint, which can effectively prevent the penetration of moisture or other liquids and protect the screw part 1 and the reinforcing bar part 2.
[0040] Preferably, in order to further ensure the life of the screw part 1, the material of the screw part 1 is selected as stainless steel.
[0041] In addition, the third support end 211 is provided with an external thread (not shown in the figure), such as Figure 1 As shown, the main reinforcing bar 21 is threadedly connected to the main threaded rod 11 and / or the auxiliary threaded rod 12 through a sleeve 3 with internal threads. This allows the number of reinforcing bars 2 to be selected according to the size of the concrete volume, thus avoiding material waste.
[0042] Working principle:
[0043] In use, the main screw 11 is fixed to the connecting frame. Then, as the concrete is poured and formed, the screw part 1 and the reinforcing bar part 2 will be embedded in the concrete. During the concrete pouring, the workers need to continuously stir and level the unformed concrete. In this process, stirring pressure is applied to the multiple fibers 232 on the side reinforcement 231. Since the fibers 232 have cracks 2321, the fibers 232 under pressure will disperse into multiple short, dispersed fibers embedded in the concrete, which plays a role in preventing cracking.
