Description

Technical Field

[0001] The utility model relates to the technical field of building components, in particular to an arched embedded part for building concrete. Background Art

[0002] In engineering structures such as bridges and large buildings, steel strands are key load-bearing components, and their installation position and degree of tightening are crucial to the safety and stability of the structure. To solve these problems, technicians are actively exploring. For example, Chinese patent CN211948916U discloses a concrete embedded part for civil construction, which uses multiple sets of limiting plates to achieve firm fixation of the embedded part in the concrete. However, this solution still needs to be improved: it does not fully consider the guidance and tightening requirements of the steel strands during installation, resulting in dislocation and loosening of the steel strands. At the same time, the embedded parts on the market are diverse in form and the interface standards are not unified, especially the steel strand embedded parts without threaded interfaces, which bring hidden dangers to the quality and safety of the project. Therefore, it is still necessary to further optimize the setting of the embedded parts to meet the installation and tightening requirements of the steel strands. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an arched embedded part for building concrete.

[0004] The technical solutions adopted in this utility model are as follows:

[0005] An arched embedded part for building concrete, including an embedded part arranged in a strip shape, the cross-section of the embedded part is I-shaped, and the embedded part is bent in an arc shape along the long side direction, wherein: the embedded part includes a lower bottom, an upper top and a middle part that are integrally processed and formed, wherein the lower bottom and the upper top are both penetrated by a through hole, and a steel strand for bridges is penetrated through the through hole; adjacent through holes are arranged at intervals in an arc shape; the surface of the middle part is wavy, and reinforcing ribs arranged along the penetration direction of the through hole are vertically arranged.

[0006] This technical solution achieves effective restraint, guidance and tightening of the steel strands by improving the shape of the embedded parts. Specifically, the embedded parts are arched, which can convert the vertical load they receive into axial pressure along the arch, better adapting to the stress distribution in the concrete and avoiding structural damage caused by stress concentration. The I-shaped cross-section has a large cross-sectional moment of inertia, which can effectively resist bending deformation and improve the bending stiffness of the embedded parts. By improving the shape of the embedded parts, the material usage can be reduced while ensuring strength, thereby reducing costs. The wavy shape of the middle part can increase the toughness of the embedded parts, enabling them to better absorb energy when subjected to external forces and reduce brittle failure. The wavy structure can change the stress transmission path in the embedded parts, making the stress distribution more uniform and avoiding excessive local stress. By rationally setting the position and number of reinforcing ribs, the stress state of the embedded parts can be improved. The integrated processing and molding can reduce welding, connection and other processes in the production process, improve production quality, ensure that the connections between the various parts of the embedded parts are firm and reliable, and avoid problems such as loosening or breakage during use. The through holes arranged in an arc shape can optimize the arrangement of the steel strands, making them better adapted to the stress distribution and deformation requirements in the concrete. The rational arrangement of the through holes and the through connection of the steel strands ensure a firmer and more reliable connection between the embedded parts and the concrete.

[0007] In addition, the above-mentioned arched embedded part for building concrete according to the present invention also has the following additional technical features:

[0008] According to an embodiment of the present invention, the embedded parts and the steel strands are embedded in the concrete to form a whole.

[0009] This technical solution achieves integrated embedding of the arched embedded parts and concrete by adjusting the combination method of the arched embedded parts for building concrete and the steel strands.

[0010] According to an embodiment of the present invention, the lower bottom and the upper top are recessed inward along the edges to form retaining edges for limiting.

[0011] This technical solution realizes the limiting function of the embedded part by forming a retaining edge by inwardly recessing the edges of the lower bottom and the upper top.

[0012] According to one embodiment of the present invention, the cross section of the lower bottom portion is larger than the cross section of the upper top portion; and the cross section of the middle portion is a trapezoid that is wider at the bottom and narrower at the top.

[0013] This technical solution enhances the structural stability of the embedded part by setting the cross section of the bottom to be larger than the cross section of the top and the cross section of the middle part to be trapezoidal.

[0014] According to one embodiment of the present invention, the number of through holes in the lower bottom portion and the upper top portion is consistent with the number of steel strands that need to be tightened.

[0015] This technical solution ensures the tightening of the steel strands and the effective use of embedded parts by matching the number of through holes on the lower bottom and upper top with the number of steel strands.

[0016] According to an embodiment of the present invention, an opening inclined outward is provided at the edge of the through hole.

[0017] In the technical solution, an opening inclined outward is provided at the edge of the through hole, thereby facilitating the insertion and fixation of the steel strand and improving the practicality of the embedded part.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) By improving the shape of the embedded parts, the effective restraint, guidance and tightening of the steel strands can be achieved; the embedded parts are arched, which can convert the vertical load into axial pressure along the arch, better adapt to the stress distribution in the concrete, and avoid structural damage caused by stress concentration;

[0020] (2) The I-shaped cross section and wavy middle part not only improve the bending stiffness and toughness of the embedded parts, but also make the stress distribution more uniform and reduce the risk of brittle failure;

[0021] (3) The opening with the edge of the through hole tilted outwards facilitates the insertion and fixation of the steel strand, thereby improving the practicality and construction efficiency of the embedded parts. BRIEF DESCRIPTION OF THE DRAWINGS
