Description

A connection component between a concrete foundation and a steel pipe column Technical Field

[0001] This application relates to the field of building technology, specifically to a connection component between a concrete foundation and a steel pipe column. Background Technology

[0002] In modern construction engineering, the connection between concrete foundations and steel pipe columns is a crucial element in ensuring the stability and safety of building structures. By firmly connecting the steel pipe columns to the concrete foundation, loads can be effectively transferred, enhancing the overall load-bearing capacity and seismic performance of the building.

[0003] Currently, the common connection method involves pre-embedding the reinforcing bars for connecting the steel pipe columns within the foundation before pouring the concrete. After the concrete hardens, the steel pipe columns are then welded to the pre-embedded threaded connecting columns or fixed using other methods. However, this traditional method has many drawbacks in actual construction. Due to the lack of effective positioning measures, the pre-embedded threaded connecting columns are prone to displacement, tilting, and uneven height during concrete pouring, leading to inaccurate rebar positioning. Once the rebar positioning deviates, it not only affects the connection strength between the steel pipe column and the concrete foundation, reducing the stability of the building structure, but may also require significant time and cost for rework correction, severely impacting construction progress and project quality.

[0004] Therefore, it is necessary to provide a connection component between the concrete foundation and the steel pipe column to solve the above problems. Summary of the Invention

[0005] In view of the above-mentioned problems in the prior art, the purpose of this application is to provide a connection component between a concrete foundation and a steel pipe column to solve the problems mentioned in the background art.

[0006] The technical solution adopted by this application to solve its technical problem is: a connection component between a concrete foundation and a steel pipe column, including a lower concrete foundation and a reinforcing cage formed by casting. The bottom of the reinforcing cage is cast in the lower concrete foundation. A top circumferential reinforcing bar in a horizontal state is welded to the top of the reinforcing cage. A positioning plate is placed on the top of the top circumferential reinforcing bar. Several adjusters are fixedly connected in the positioning plate. A threaded connecting column for connecting the steel pipe column is provided in the adjuster.

[0007] The regulator has a concentrically arranged nested block and a base. A base is snapped into the base, and a connecting seat is fixedly connected to the top of the base. Several spring pieces are arranged circumferentially on the connecting seat. The threaded connecting post passes through the nested block, the base, the base, and the connecting seat. Rotating the nested block counterclockwise will cause the spring pieces to tighten inward, thereby fixing the threaded connecting post.

[0008] Furthermore, the center of the nested block is hollow and a patterned part is pressed on the top outer peripheral wall. The lower outer peripheral of the nested block is provided with an external thread, and the top of the base is provided with an internal thread that matches the external thread. The inner wall surface of the hollow part near the bottom of the nested block is a conical surface with a diameter that gradually increases from top to bottom. The conical surface is conical.

[0009] Each of the spring pieces has an inclined surface at its tip that mates with a conical surface, the inclined surface being a part of the conical surface.

[0010] Furthermore, the base is hollow at the center and has a positioning groove on its outer peripheral wall that connects to the positioning plate.

[0011] Furthermore, the bottom wall of the base is provided with a plurality of protrusions spaced in a ring along the circumference. The center of the base is hollow and the base is located in the hollow part of the base. The outer peripheral wall of the base is provided with a plurality of limiting grooves that match the protrusions along the circumference. The protrusions and limiting grooves correspond one-to-one, and the protrusions are embedded in the corresponding limiting grooves.

[0012] Furthermore, the upper end of the threaded connecting column has a threaded portion, and the lower end has a pre-embedded portion, which is located inside the adjuster.

[0013] The beneficial effects of this application are as follows: The connection component between the concrete foundation and the steel pipe column provided by this application, by setting an inclined surface on the nesting block and a conical surface on the spring plate, allows the inclined surface and the conical surface to match and clamp the threaded connection column. By rotating the nesting block, the threaded connection column can be clamped or released, which makes it easier to adjust the height of the threaded connection column and make its positioning more accurate. After fixing several threaded connection columns with stirrups before pouring concrete, the threaded connection columns can be fixed more firmly and will not displace, which increases the connection strength between the threaded connection column and the concrete foundation and improves stability.

Detailed Implementation

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0027] As shown in Figures 1-6, this application provides a technical solution: a connection component between a concrete foundation and a steel pipe column, including a lower concrete foundation 1 and a reinforcing cage 5 formed by casting. The bottom of the reinforcing cage 5 is cast in the lower concrete foundation 1. A horizontal top circumferential reinforcing bar 6 is welded to the top of the reinforcing cage 5. A positioning plate 8 is placed on the top of the top circumferential reinforcing bar 6. Several adjusters 9 are fixedly connected in the positioning plate 8. A threaded connecting column 3 for connecting the steel pipe column 2 is provided in the adjuster 9.

[0028] The regulator 9 has a concentrically arranged nested block 91 and a base 92. A base 93 is snapped into the base 92. A connecting seat 94 is fixedly connected to the top of the base 93. Several spring pieces 941 are arranged circumferentially on the connecting seat 94. A threaded connecting post 3 passes through the nested block 91, the base 92, the base 93 and the connecting seat 94. Rotating the nested block 91 counterclockwise will cause the spring pieces 941 to tighten inward, thereby fixing the threaded connecting post 3.

[0029] The center of the nested block 91 is hollow and the top outer peripheral wall is pressed with a patterned part 911. The lower outer peripheral wall of the nested block 91 is provided with an external thread 912. The top of the base 92 is provided with an internal thread 921 that matches the external thread 912. The inner wall surface of the hollow part near the bottom of the nested block 91 is a conical surface 913 with a diameter that gradually increases from top to bottom. The conical surface 913 is conical.

[0030] Each spring piece 941 has an inclined surface 9411 at its top end that mates with the conical surface 913. The inclined surface 9411 is part of the conical surface.

[0031] The base 92 is hollow at the center and has a positioning groove 922 on its outer peripheral wall that connects to the positioning plate 8.

[0032] The bottom wall of the base 92 is provided with a plurality of protrusions 923 at circumferential intervals. The center of the base 93 is hollow and is located in the hollow part of the base 92. The outer peripheral wall of the base 93 is provided with a plurality of limiting grooves 931 that match the protrusions 923. The protrusions 923 and the limiting grooves 931 correspond one-to-one, and the protrusions 923 are embedded in the corresponding limiting grooves 931.

[0033] The upper end of the threaded connecting column 3 has a threaded part 31, and the lower end has a pre-embedded part 32, which is located inside the adjuster 9.

[0034] In one embodiment, the connection component is used in this way.

[0035] Specifically, the prepared steel cage 5 is placed in the foundation, and concrete is poured to fix the bottom of the steel cage 5 to form the lower concrete foundation 1. A positioning plate 8 is placed on the top circumferential steel bar 6 at the very top of the steel cage 5. The adjuster 9 is installed in the appropriate position on the positioning plate 8 according to the construction needs. The pre-embedded part 32 of the threaded connecting column 3 is slowly inserted downward from the adjuster 9. The threaded connecting column 3 passes through the nesting block 91, the base 92 and the base 93 in sequence. When the threaded connecting column 3 reaches the designated position, the nesting block 91 is turned counterclockwise by hand. The nesting block 91 moves downward along the base 92. When the conical surface 913 moves downward, the inclined surface 9411 that matches it gathers inward. Thus, the spring piece 941 gradually clamps the pre-embedded part 32 inward, so that the threaded connecting column 3 will not fall downward.

[0036] The threaded connecting columns 3 are sequentially clamped in the adjuster 9 in the same manner as described above. At this time, it is only necessary to rotate the adjuster 9 to fix or loosen the clamping of the threaded connecting columns 3. It is very convenient to adjust the height of the threaded connecting columns 3 to be flush with other threaded connecting columns 3 without performing any other complicated operations. After the top of the threaded part 31 is flush, the pre-embedded part 32 at the lower end of the positioning plate 8 is fixed with the stirrup 7. Then, concrete is poured again. When the concrete is about to reach the bottom of the positioning plate 8, the nesting block 91 is rotated clockwise in sequence, so that the nesting block 91 moves upward along the base 92. When the conical surface 913 moves upward, it disengages from the inclined surface 9411, causing the spring piece 941 to expand outward, thereby disengaging from the clamping of the threaded connecting column 3. The positioning plate 8 is moved upward to remove the positioning plate 8 from the threaded connecting column 3. Then, concrete is poured again until the designated position is reached, forming the upper concrete foundation 11. A part of the threaded part 31 is also embedded in the upper concrete foundation 11.

[0037] First, fastening bolts 4 are connected to the exposed threaded part 31. Then, the connecting plate 21 at the bottom of the steel pipe column 2 is aligned with the threaded part 31. The fastening bolts 4 are then fixed to the top of the connecting plate 21, so that the connecting plate 21 is located between the upper and lower fastening bolts 4. Then, the connection between the connecting plate 21 and the upper concrete foundation 11 is filled with concrete to complete the connection between the concrete foundation and the steel pipe column 2.

[0038] In summary, this component clamps the threaded connecting column 3 by setting a conical surface 913 on the nesting block 91 and an inclined surface 9411 on the spring piece 941, so that the conical surface 913 and the inclined surface 9411 match. By rotating the nesting block 91, the threaded connecting column 3 can be clamped or released, which makes it easier to adjust the height of the threaded connecting column 3 and make its positioning more accurate. After fixing several threaded connecting columns 3 with stirrups 7 before pouring concrete, the threaded connecting columns 3 are more firmly fixed and do not displace. This increases the connection strength between the threaded connecting column 3 and the concrete foundation and improves stability. It solves the technical problem that in actual construction, due to the lack of effective positioning measures, the pre-embedded threaded connecting columns are prone to displacement, tilting and uneven height during concrete pouring, resulting in inaccurate positioning of the reinforcing bars. Once the positioning of the reinforcing bars is deviated, it will not only affect the connection strength between the steel pipe column and the concrete foundation and reduce the stability of the building structure, but may also require a lot of time and cost to rework and correct, seriously affecting the construction progress and project quality.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
