Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building structures, and in particular to an inserted steel column base mounting structure and a mounting method. BACKGROUND

[0002] The inserted steel column base is a way of connecting a steel column and a concrete base, which is a column base structure that directly inserts the lower end of the steel column into the reserved cup opening of the concrete base, and then forms an integral connection between the steel column and the base by secondary pouring of concrete. While ensuring structural stability, it has the advantages of convenient construction, high precision and low cost, and is widely used in steel structures such as high-rise buildings, industrial plants, bridges and other structures that need to bear large loads.

[0042] The technical solutions of the present application will be further illustrated below in conjunction with the drawings and through specific embodiments.

[0043] The purpose of the present application is to provide a plug-in steel column foot mounting structure and mounting method, which ensures the verticality of the steel column foot and has simple assembly process and high efficiency.

[0044] As Figures 1-8As shown in the drawings, the present application provides an insertion type steel column foot mounting structure, which comprises a mounting base 1, a centering mechanism 2, a locking mechanism 3 and a steel column foot 4. The mounting base 1 has a mounting groove 10, and the groove bottom of the mounting groove 10 is a plane; the centering mechanism 2 is arranged on the groove bottom of the mounting groove 10, and comprises a centering base column 21 and a centering plate 22; the inside of the centering base column 21 is provided with a containing cavity 210, and the outer wall of the centering base column 21 is provided with a lower pressing through hole 211 and a protruding hole 212 which are communicated with the containing cavity 210; the centering plate 22 is connected to the centering base column 21 and is perpendicular to the groove bottom of the mounting groove 10; the locking mechanism 3 comprises a locking base column 31, a lower pressing plate 32, a movable plate 33, an elastic member 34 and a locking rod 35; the locking base column 31 is arranged in the containing cavity 210; the lower pressing plate 32 is arranged through the lower pressing through hole 211 and is connected to the movable plate 33; the movable plate 33 is located in the containing cavity 210 and is provided with a connecting hole 331; one end of the elastic member 34 is connected to the locking base column 31, and the other end is connected to the locking rod 35; the locking rod 35 can press the movable plate 33 under the driving of the elastic member 34; the bottom surface of the steel column foot 4 is provided with a hollow groove, the outer wall of the steel column foot 4 is provided with a limiting groove 41 and a positioning hole 42 which are communicated with the hollow groove, and one end of the limiting groove 41 extends to the bottom surface of the steel column foot 4; the steel column foot 4 can be aligned with the centering plate 22 through the limiting groove 41 and is pressed downward along the centering plate 22 to press the lower pressing plate 32.

[0045] When the steel column foot 4 is mounted, first, the centering plate 22 which is perpendicular to the groove bottom of the mounting groove 10 provides vertical guidance for the downward movement of the steel column foot 4, so that the steel column foot 4 obtains preliminary vertical positioning during the installation process, effectively avoiding the inclination caused by inaccurate initial position during installation; then the steel column foot 4 presses the lower pressing plate 32 to drive the movable plate 33 to move downward, so that the connecting hole 331, the protruding hole 212 and the positioning hole 42 are communicated, and at the same time the locking rod 35 is arranged through the above connecting hole 331, protruding hole 212 and positioning hole 42 in sequence under the driving of the elastic member 34 to fix the steel column foot 4 in the vertical state, thereby completing the installation of the steel column foot 4. The whole assembly process is simple, which reduces the time loss and precision deviation caused by human operation errors or repeated debugging, and efficiently and accurately realizes the installation of the insertion type steel column foot 4.

[0046] In order to more conveniently insert the steel column foot 4 into the mounting groove 10 along the vertical direction, and more smoothly insert the centering plate 22 into the limiting groove 41.

[0047] Specifically, as shown in the drawings, Figure 5 the top end of the centering base column 21 gradually inclines downward from the center to the periphery to form a guide end; when the steel column foot 4 approaches the guide end of the centering base column 21, the guide end can gradually guide the steel column foot 4 to be inserted into the mounting groove 10 along the vertical direction, which lays a foundation for the subsequent limiting groove 41 of the steel column foot 4 to be aligned with the centering plate 22.

[0048] In the embodiment, the bottom end of the centering base column 21 is a quadrangular prism, and the guide end is a quadrangular truncated pyramid.

[0049] In other embodiments, the bottom end of the centering base column 21 can also be a cylinder, and the guide end is a cone. The shape of the centering base column 21 is not specifically limited.

[0050] Specifically, as shown in Figure 4 The bottom surface of the steel column base 4 is provided with a limiting inclined groove 43 communicating with the hollow groove, and the limiting inclined groove 43 communicates with the limiting groove 41. The groove wall of the limiting inclined groove 43 is inclined away from the limiting groove 41. When the centering plate 22 approaches the bottom surface of the steel column base 4 and is ready to be inserted into the limiting groove 41, it will first contact the inclined groove wall of the limiting inclined groove 43, and gradually adjust its position along the guide direction of the inclined groove wall to slide towards the limiting groove 41, thereby accurately extending into the limiting groove 41.

[0051] More specifically, the centering plate 22 is provided with a guide inclined surface 221 inclined towards the centering base column 21 at one end of the slot opening of the mounting groove 10. When the centering plate 22 is inserted into the limiting groove 41, the limiting groove 41 slides along the guide inclined surface 221. The provision of the guide inclined surface 221 can guide the steel column base 4 to the accurate installation position.

[0052] Further, in order to enhance the vertical accuracy and stability of the steel column base 4.

[0053] Specifically, as shown in Figure 4 The centering plate 22 is provided with a plurality of centering plates 22, which are uniformly distributed around the centering base column 21 in the circumferential direction, and the steel column base 4 is provided with a plurality of limiting grooves 41 uniformly distributed in the circumferential direction of the outer wall. The plurality of centering plates 22 can be inserted one by one into the plurality of limiting grooves 41. The plurality of centering plates 22 inserted into the plurality of limiting grooves 41 can restrict the steel column base 4 from multiple directions, making the installation path of the steel column base 4 in the vertical direction more accurate, effectively preventing the steel column base 4 from tilting or deviating during vertical descent. Moreover, the uniform distribution of the centering plate 22 and the limiting groove 41 combination makes the steel column base 4 able to evenly distribute the force to each centering plate 22 when subjected to external force, collectively resisting external force, preventing the steel column base 4 from tilting or shaking, thereby enhancing the stability of the entire installation structure.

[0054] In this embodiment, the steel column base 4 is a quadrangular prism. Four limiting grooves 41 are evenly arranged along the circumference of the outer wall of the steel column base 4. Four centering plates 22 are also provided, evenly distributed around the centering base column 21. The one-to-one correspondence between the four limiting grooves 41 and the four centering plates 22 enables precise 90-degree indexing and positioning in the circumferential direction, effectively preventing rotational deviation of the steel column base 4. Furthermore, in the vertical direction, the four centering plates 22 strictly constrain the downward movement path of the steel column base 4, ensuring its vertical positioning, greatly improving installation accuracy and reducing the risk of uneven stress on the subsequent structure due to inaccurate positioning.

[0055] In other embodiments, the steel column base 4 can also be a cylinder. The steel column base 4 has three limiting grooves 41 evenly arranged along the outer wall circumference. Three centering plates 22 are provided. The three centering plates 22 are evenly distributed around the centering base column 21. The three limiting grooves 41 correspond one-to-one with the three centering plates 22. Precise indexing is achieved in the circumferential direction at equal intervals of 120 degrees, which effectively constrains the rotational freedom of the column base and prevents it from deviating around the circumference.

[0056] The shape of the steel column base 4, the number of the middle plate 22 and the limiting groove 41 are not specifically defined here.

[0057] More specifically, such as Figures 5-6 As shown, for each centering plate 22, there are two pressing through holes 211 and two pressing plates 32. The centering plate 22 is located between the two pressing through holes 211, and the two pressing plates 32 are inserted one-to-one through the two pressing through holes 211 and connected to the movable plate 33. When the steel column foot 4 is pressed down, the pressing plates 32 on both sides of each centering plate 22 are simultaneously subjected to force, which transmits the pressing force to the movable plate 33 more evenly. This avoids local deformation of the pressing plate 32 due to excessive force at a single point, ensures the stability of the force during transmission, and makes the entire locking mechanism 3 operate more smoothly and reliably, laying the foundation for the precise locking of the steel column foot 4 in the future.

[0058] Specifically, the centering plate 22 is provided with a guide groove 222, and the lower pressure plate 32 is inserted into the guide groove 222 and can move along the guide groove 222. The guide groove 222 provides a precise movement path for the lower pressure plate 32, so that the movement trajectory of the lower pressure plate 32 during the pressing process of the steel column foot 4 is strictly limited, avoiding the misalignment of the connecting hole 331, the protruding hole 212 and the positioning hole 42 due to deviation or shaking during the pressing process, further ensuring the cooperation between the steel column foot 4 and the centering mechanism 2 and the locking mechanism 3, and improving the stability of the entire installation structure.

[0059] In this embodiment, four centering plates 22 are provided, and each centering plate 22 has guide grooves 222 on both opposite sides. The two pressure plates 32 provided for each centering plate 22 can be inserted into the two guide grooves 222 one by one.

[0060] Specifically, the connecting holes 331, the protruding holes 212, the positioning holes 42, the elastic members 34 and the locking rods 35 are respectively provided with multiple, by pressing the pressing plates 32, the multiple connecting holes 331, the multiple protruding holes 212 and the multiple positioning holes 42 can one by one correspond and communicate, the multiple elastic members 34 can correspond to drive the multiple locking rods 35 one by one correspondingly threaded in the multiple connecting holes 331, the multiple protruding holes 212 and the multiple positioning holes 42. The multiple locking rods 35 are simultaneously threaded in the corresponding hole positions under the driving of the multiple elastic members 34, not only enhance the connection strength between the steel column foot 4 and the centering mechanism 2, but also provide the steel column foot 4 with all-round vertical constraint, which can ensure that the steel column foot 4 always maintains vertical state.

[0061] In the embodiment, the movable plate 33 is provided with four, as shown in Figure 8 Each two pressing plates 32 correspond to one movable plate 33, and each movable plate 33 is provided with two connecting holes 331 along the length direction, a total of eight connecting holes 331, corresponding to Figure 5 As shown, the protruding holes 212 are also provided with eight, two protruding holes 212 for a group, four groups of protruding holes 212 are uniformly distributed around the centering base column 21, and the two protruding holes 212 of each group are distributed along the length direction of the centering base column 21 and located directly above the centering plate 22; corresponding to Figure 4 As shown, the positioning holes 42 are also provided with eight, two positioning holes 42 for a group, four groups of positioning holes 42 are uniformly distributed around the steel column foot 4, and the two positioning holes 42 of each group are distributed along the length direction of the steel column foot 4 and located directly above the limiting groove 41; corresponding to Figure 3 and Figure 6 As shown, the elastic members 34 are provided with eight, two elastic members 34 for a group, four groups of elastic members 34 are uniformly distributed around the locking base column 31, and the two elastic members 34 of each group are distributed along the length direction of the centering base column 21, and each elastic member 34 is connected with a locking rod 35. The setting of four independent movable plates 33 means that even if the connecting holes 331 on one movable plate 33 do not communicate with the corresponding protruding holes 212 and positioning holes 42, it does not affect the communication of the connecting holes 331 on the other three movable plates 33 with the corresponding protruding holes 212 and positioning holes 42, so the setting flexibility and adaptability are stronger, and the steel column foot 4 can be more reliably fixed in the vertical state.

[0062] In other embodiments, the movable plate 33 can also be provided with two, and the two movable plates 33 are both L-shaped, each movable plate 33 is provided with two connecting holes 331 on the two sides forming the L-shaped angle, and the two connecting holes 331 are distributed along the length direction of the movable plate 33, and the other settings are the same as those in the above embodiment, which will not be repeated here.

[0063] Specifically, as shown in Figure 3 andFigure 7 As shown, the locking mechanism 3 further comprises a sleeve 36 connected to the locking base column 31, the elastic member 34 is located in the sleeve 36, and the locking rod 35 can extend into the sleeve 36. The sleeve 36 limits and guides the movement of the elastic member 34 and the locking rod 35, so that the movement trajectory of the locking rod 35 is stable and controllable, effectively preventing the locking rod 35 from shaking and deviating from the predetermined path during reciprocating movement, ensuring that the locking rod 35 can accurately and accurately penetrate into the corresponding hole position each time, improving the working precision of the locking mechanism 3, and ensuring the reliability of the steel column foot 4 installation.

[0064] More specifically, as shown in the drawings, Figure 6 The end of the locking rod 35 away from the elastic member 34 is provided with a circular arc head, which facilitates the insertion of the locking rod 35 into the corresponding hole position.

[0065] The present application also provides an insertion type steel column foot mounting method, which adopts the above-mentioned insertion type steel column foot mounting structure, comprising:

[0066] Insert the steel column foot 4 into the installation groove 10, so that the limiting groove 41 is aligned with the centering plate 22, and the lower moving extrusion of the lower pressing plate 32 drives the movable plate 33 to move downward, so that the connecting hole 331, the protruding hole 212 and the positioning hole 42 are communicated, and the locking rod 35 can be sequentially arranged in the connecting hole 331, the protruding hole 212 and the positioning hole 42 under the driving of the elastic member 34, and the steel column foot 4 is fixed.

[0067] By using the above-mentioned mounting method, only the limiting groove 41 of the steel column foot 4 needs to be aligned with the centering plate 33 and moved downward, and the steel column foot 4 can automatically trigger the locking mechanism 3 to complete the fixing work in the process of moving downward, which does not need manual intervention, is simple to operate and has high assembly efficiency.

[0068] Obviously, the above embodiments of the present application are only examples for clear illustration of the present application, and are not a limitation on the embodiments of the present application.
