Description

Technical Field

[0001] The present application relates to the technical field of building construction, and in particular to a pre-embedded wall connecting member structure for a shallow cylindrical silo wall. Background Art

[0002] The shallow silo is a cylindrical reinforced concrete structure with a main concrete grade of C35. The cylinder wall structure is constructed using slipforms. Due to the particularity of the silo, the construction workers need to tie the upper and lower sliding formwork platforms to the cylinder wall structure to ensure its stability.

[0003] The prior art provides a pre-embedded wall connection device, including a pre-embedded steel plate, pre-embedded steel bars and a connecting plate. The pre-embedded steel bars are embedded in the wall of the silo, and the pre-embedded steel bars extend into the concrete structure of the silo. The connecting plate is fixed to the outward side of the pre-embedded steel bars so that the connecting plate extends out of the silo, and then is hung or slidably connected with a pre-connector.

[0004] However, when the above technical solution is applied, the stability of the pre-connector installed on the silo is weak and it is easy to fall off, which not only affects the construction efficiency but also poses a threat to the safety of the construction workers. Summary of the invention

[0005] In order to improve the stability of the pre-connector when it is installed on the silo, the present application provides a pre-embedded wall connecting member structure for the wall of a shallow circular silo.

[0006] The present application provides a pre-embedded wall connecting member structure for a shallow circular silo wall, which adopts the following technical solution:

[0007] A pre-embedded wall connection structure for a shallow circular silo wall comprises a pre-embedded steel plate, pre-embedded steel bars and a wall connection member, wherein the pre-embedded steel plate is pre-embedded in the silo wall, the pre-embedded steel bars are fixed to the side walls of the pre-embedded steel plate and extend into the concrete structure of the silo, the wall connection member is fixed to the other side wall of the pre-embedded steel plate and extends out of the silo, and a reinforcement assembly is arranged on the wall connection member.

[0008] By adopting the above technical solution, combined with embedded steel plates, embedded steel bars and wall connecting parts, a stable support system is formed. The embedded steel plates are embedded in the silo wall, which increases the stability of the structure; the embedded steel bars are fixed to the side walls of the embedded steel plates and extend into the concrete structure, further enhancing the firmness of the structure; and the wall connecting parts are fixed to the other side wall of the embedded steel plates and extend out of the silo, providing convenience for external connection. This structure not only improves the overall strength and stability of the shallow circular silo wall, but also facilitates subsequent maintenance and expansion operations, effectively improving the safety of the overall structure.

[0009] Preferably, a weld cutout A is provided on a peripheral wall of one end of the wall connecting member close to the embedded steel plate, 0°<A<80°, and the weld cutout is fully welded.

[0010] By adopting the above technical solution, a weld cutout A is opened on the peripheral wall of one end of the wall connecting member close to the embedded steel plate, and full welding is performed, which significantly improves the connection strength between the wall connecting member and the embedded steel plate. This operation increases the firmness of the welding and effectively reduces the safety hazards caused by loose welding. At the same time, by reasonably controlling the angle of the weld cutout A between 0° and 80°, the welding quality and the rationality of the structure are ensured.

[0011] Preferably, the edge of the wall connecting member close to one end of the embedded steel plate is provided with a flange, and the flange is attached to the outer wall of the silo.

[0012] By adopting the above technical solution, the flange design enables the wall connection parts to fit more closely to the outer wall of the silo, thereby enhancing the integrity and stability of the structure, reducing the gaps at the joints to a certain extent, reducing the impact of external factors (such as wind, rain, etc.) on the structure, and helping to improve the load-bearing capacity and service life of the silo.

[0013] Preferably, the reinforcement assembly includes a steel bar head fixed to the outer wall of the wall connection member, which is used to reinforce and prevent the wall connection member from slipping.

[0014] By adopting the above technical solution, the presence of the steel bar head increases the friction between the wall connection member and the external structure, effectively preventing the wall connection member from shifting or being damaged due to sliding or external force, which helps to improve the safety of the structure and enhance the strength of the structure.

[0015] Preferably, the wall connecting member is a steel tube body, an even number of the steel bar heads are provided, two of the steel bar heads form a group, and are symmetrically arranged along the length center line of the wall connecting member.

[0016] By adopting the above technical solution, the steel tube body is used as the wall connection member, which enhances the bearing capacity and stability of the structure. At the same time, an even number of steel bar heads are arranged symmetrically on both sides of the length center line of the wall connection member, ensuring uniform distribution of force and reducing structural tilt or damage caused by unilateral force, thereby helping to improve the stability of the overall structure, simplify the construction process, and improve installation efficiency.

[0017] Preferably, the reinforcement assembly includes an anchoring steel bar, and the anchoring steel bar is fixed to an end of the embedded steel bar away from the embedded steel plate.

[0018] By adopting the above technical solution, the anchor steel bar is fixed at the end of the embedded steel bar away from the embedded steel plate, which helps to enhance the tensile strength of the embedded wall connection structure and can reduce the loosening or pulling out of the embedded steel bar due to external force, thereby ensuring the stability and safety of the overall structure.

[0019] Preferably, a plurality of the embedded steel bars are provided, and the extension direction of the anchor steel bars is perpendicular to the extension direction of the embedded steel bars, presenting an "L"-shaped structure; and / or a plurality of the anchor steel bars are provided at the end of each of the embedded steel bars, and the plurality of anchor steel bars are distributed in an umbrella shape.

[0020] By adopting the above technical solution, a more complex support system is formed by combining multiple embedded steel bars with anchor steel bars. The "L"-shaped structure forms a vertical support between the anchor steel bars and the embedded steel bars, which enhances the stability of the structure; while the multiple anchor steel bars distributed in an umbrella shape further expand the support area and improve the anti-overturning ability, thereby achieving the purpose of improving the bearing capacity and anti-deformation performance of the embedded wall connection structure.

[0021] Preferably, the embedded steel bars and the embedded steel plates, and the wall connecting members and the embedded steel plates are vertically arranged.

[0022] By adopting the above technical solution, the vertical setting relationship between the embedded steel bars, wall ties and embedded steel plates is ensured, so that the entire embedded wall tie structure can form an effective force transmission path when subjected to force, reducing problems such as stress concentration or reduced transmission efficiency caused by angle deviation, thereby ensuring the bearing capacity and service life of the overall structure. At the same time, the vertical setting is also conducive to simplifying the positioning and installation operations during the construction process, thereby improving construction efficiency.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. Combining the embedded steel plates, embedded steel bars and wall connectors, a stable support system is formed. The embedded steel plates are embedded in the silo wall, which increases the stability of the structure. The embedded steel bars are fixed to the side walls of the embedded steel plates and extend into the concrete structure, further enhancing the firmness of the structure. The wall connectors are fixed to the other side walls of the embedded steel plates and extend out of the silo, providing convenience for external connections. This structure not only improves the overall strength and stability of the shallow circular silo wall, but also facilitates subsequent maintenance and expansion operations, effectively improving the safety of the overall structure.

[0025] 2. A weld cutout A is opened on the peripheral wall of the wall connecting piece close to the embedded steel plate, and full welding is performed, which significantly improves the connection strength between the wall connecting piece and the embedded steel plate. This operation increases the firmness of the welding and effectively reduces the safety hazards caused by weak welding;

[0026] 3. The steel tube is used as the wall connection part to enhance the bearing capacity and stability of the structure. At the same time, an even number of steel bar heads are arranged symmetrically on both sides of the length center line of the wall connection part to ensure uniform distribution of force and reduce structural tilt or damage caused by unilateral force, thereby helping to improve the stability of the overall structure, simplify the construction process, and improve installation efficiency.

[0030] The following is combined with Figure 1-2 This application is described in further detail.

[0031] The embodiment of the present application discloses a pre-embedded wall connecting member structure for the wall of a shallow circular silo.

[0032] The shallow silo of the present application is a cylindrical reinforced concrete structure with a diameter of 22.0m, a cornice elevation of 39.00m, a cylinder wall thickness of 260mm, and a main concrete grade of C35.

[0033] Reference Figure 1 A pre-embedded wall connecting member structure for a shallow circular silo wall comprises a pre-embedded steel plate 1, pre-embedded steel bars 2 and a wall connecting member 3. The pre-embedded steel plate 1 is embedded in the wall of the silo 4. The pre-embedded steel bars 2 are fixed to the side wall of the pre-embedded steel plate 1 and extend into the concrete structure of the silo 4. The wall connecting member 3 is fixed to the other side wall of the pre-embedded steel plate 1 and extends out of the silo 4. A reinforcement component 5 is arranged on the wall connecting member 3.

[0034] The present application combines the embedded steel plate 1, the embedded steel bar 2 and the wall connecting member 3 to form a stable support system, so that the embedded steel plate 1 is embedded in the wall of the silo 4, the embedded steel bar 2 is fixed to the side wall of the embedded steel plate 1 and extends into the concrete structure, and the wall connecting member 3 is fixed to the other side wall of the embedded steel plate 1 and extends out of the silo 4, so as to increase the overall strength and stability of the shallow circular silo wall, facilitate subsequent maintenance and expansion operations, and thus improve the safety of the overall structure.

[0035] Specifically, refer to Figure 1 and Figure 2The reinforcement component 5 includes an anchoring steel bar 52, which is fixed to one end of the embedded steel bar 2 away from the embedded steel plate 1, which helps to enhance the tensile strength of the embedded wall connection member 3 structure and can reduce the loosening or pulling out of the embedded steel bar 2 due to external force, thereby ensuring the stability and safety of the overall structure.

[0036] There are multiple embedded steel bars 2, and the extension direction of the anchor steel bar 52 is perpendicular to the extension direction of the embedded steel bar 2, presenting an "L"-shaped structure; and / or multiple anchor steel bars 52 are arranged at the end of each embedded steel bar 2, and the multiple anchor steel bars 52 are distributed in an umbrella shape. In the present application, the ends of the anchor steel bars 52 can be chamfered or guide rods can be added so that the anchor steel bars 52 can easily move in the direction of the force, but no matter whether the shape structure obtained after the anchor steel bars 52 and the embedded steel bars 2 are assembled is "L"-shaped or umbrella-shaped, the anchor steel bars 52 are always anchored outward in the concrete structure of the silo 4.

[0037] The combination of multiple embedded steel bars 2 and anchoring steel bars 52 forms a more complex support system. The "L"-shaped structure forms a vertical support between the anchoring steel bars 52 and the embedded steel bars 2, thereby enhancing the stability of the structure; and the multiple anchoring steel bars 52 distributed in an umbrella shape further expand the support area and improve the anti-overturning ability, thereby achieving the purpose of improving the bearing capacity and anti-deformation performance of the embedded wall connection member 3 structure.

[0038] Reference Figure 1 and Figure 2 In the present application, a connection method between a wall connecting member 3 and an embedded steel plate 1 is provided. A weld cutout 31A is provided on the peripheral wall of one end of the wall connecting member 3 close to the embedded steel plate 1, 0°<A<80°, and the weld cutout 31 is fully welded, thereby achieving a stable connection between the wall connecting member 3 and the embedded steel plate 1.

[0039] In addition, the present application also provides another connection method between the wall connecting member 3 and the embedded steel plate 1. The edge of the wall connecting member 3 close to one end of the embedded steel plate 1 is provided with a flange, which is attached to the outer wall of the silo 4, and then the two are reinforced by welding. The design of the flange enables the wall connecting member 3 to be more closely attached to the outer wall of the silo 4, thereby enhancing the integrity and stability of the structure, reducing the gap at the connection to a certain extent, reducing the impact of external factors (such as wind, rain, etc.) on the structure, and helping to improve the load-bearing capacity and service life of the silo 4.

[0040] Reference Figure 1 and Figure 2The embedded steel bars 2 and the embedded steel plates 1, as well as the wall ties 3 and the embedded steel plates 1 are arranged vertically, so that the entire embedded wall ties 3 structure can form an effective force transmission path when subjected to force, reducing stress concentration or reduced transmission efficiency caused by angle deviation, thereby ensuring the bearing capacity and service life of the overall structure.

[0041] In addition, the reinforcement component 5 includes a steel bar head 51 fixed to the outer wall of the wall connection member 3, which is used to reinforce and prevent the wall connection member 3 from slipping. The presence of the steel bar head 51 increases the friction between the wall connection member 3 and the external structure, effectively preventing the wall connection member 3 from shifting or being damaged due to sliding or external force, thereby helping to improve the safety of the structure and enhance the strength of the structure.

[0042] The wall connecting member 3 is a steel pipe body to enhance the bearing capacity and stability of the structure. An even number of steel bar heads 51 are provided, two steel bar heads 51 form a group, and are symmetrically arranged along the length center line of the wall connecting member 3 to ensure uniform distribution of force and reduce structural inclination or damage caused by unilateral force, thereby helping to improve the stability of the overall structure, simplify the construction process, and improve installation efficiency.

[0043] Furthermore, in the present application, connecting steel bars are provided on the steel bar heads 51, and each connecting steel bar is welded and fixed to multiple steel bar heads 51 located at the same height at the same time. The ends of the connecting steel bars can also be fixed to the side walls of the embedded steel plates 1 to further improve the strength and stability of the overall structure.

[0044] The above are all preferred embodiments of the present application. The embodiments are only explanations of the present application and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
