Description

Technical Field

[0001] The invention relates to the technical field of building structures, and in particular to an insert-type steel column foot installation structure and an installation method. Background Art

[0002] Inserted steel column foot is a way to connect steel column to concrete foundation. It is a form of column foot structure that directly inserts the lower end of the steel column into the reserved cup of the concrete foundation, and then forms an integral connection between the steel column and the foundation through secondary pouring of concrete. While ensuring the stability of the structure, it has the advantages of convenient construction, high precision and low cost. It is widely used in high-rise buildings, industrial plants, bridges and other steel structures that need to bear large loads. However, it is difficult to keep the inserted steel column foot in a vertical state during the installation process, and it is easy to tilt, thus affecting the stability of the steel structure.

[0003] In response to the above problems, the prior art has designed an installation structure for an inserted steel column base, including a concrete cup-shaped foundation and a steel column base inserted into the concrete cup-shaped foundation. A plurality of adjustment brackets are fixed around the steel column base, and leveling is performed by adjusting the threaded anchor bolts on the brackets so that the steel column base reaches and maintains a vertical state.

[0004] However, the leveling operation is extremely dependent on the experience and skills of the construction workers. Since the adjustment accuracy of the threaded anchor bolts is extremely high, a slight rotation angle deviation may cause the steel column base to tilt significantly in the vertical direction, which requires repeated adjustments by the construction workers. In addition, multiple adjustment brackets need to be adjusted, making the assembly process more cumbersome and the assembly efficiency low. Summary of the invention

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0042] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0043] The object of the present invention is to provide an insertable steel column foot installation structure and installation method, which can ensure that the steel column foot is vertical while simplifying the assembly process and increasing efficiency.

[0044] like Figure 1-Figure 8As shown, the present invention provides an insert-type steel column base installation structure, including an installation base 1, a centering mechanism 2, a locking mechanism 3 and a steel column base 4. The installation base 1 has an installation groove 10, and the groove bottom of the installation groove 10 is a plane; the centering mechanism 2 is arranged at the groove bottom of the installation groove 10, and the centering mechanism 2 includes a centering base column 21 and a centering plate 22. The centering base column 21 is provided with a accommodating cavity 210 inside, and the outer wall of the centering base column 21 is provided with a downward pressure through hole 211 and a protruding hole 212 connected to the accommodating cavity 210. The centering plate 22 is connected to the centering base column 21 and is perpendicular to the groove bottom of the installation groove 10; the locking mechanism 3 includes a locking base column 31, a downward pressure plate 32, a movable plate 33, an elastic member 34 and a locking rod 35. The locking base column 31 is arranged in the accommodating cavity 210, and the downward pressure plate 32 is provided on the outer wall of the centering base column 21. 32 is passed through the downward pressing through hole 211 and connected to the movable plate 33. The movable plate 33 is located in the accommodating 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 squeeze the movable plate 33 under the drive of the elastic member 34; a hollow groove is provided on the bottom surface of the steel column foot 4, and a limiting groove 41 and a positioning hole 42 connected to the hollow groove are provided on the outer wall of the steel column foot 4, 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 move down along the centering plate 22 to squeeze the downward pressing plate 32.

[0045] When installing the steel column foot 4, firstly, the centering plate 22 perpendicular to the bottom of the installation groove 10 is used to provide a vertical guide for the downward movement of the steel column foot 4, so that the steel column foot 4 can obtain a preliminary vertical positioning during the installation process, effectively avoiding the tilt caused by the inaccurate position at the initial installation. Then, the steel column foot 4 squeezes the lower pressing plate 32 to drive the movable plate 33 to move downward, so that the connecting hole 331, the extension hole 212 and the positioning hole 42 are connected. At the same time, the locking rod 35 is driven by the elastic member 34 to penetrate the above-mentioned connecting hole 331, the extension hole 212 and the positioning hole 42 in sequence to fix the steel column foot 4 in a vertical state, thereby completing the installation of the steel column foot 4. The entire assembly process is simple, reducing the time loss and precision deviation caused by human operation errors or repeated debugging, and realizing the installation of the plug-in steel column foot 4 efficiently and accurately.

[0046] In order to facilitate the steel column foot 4 to be inserted into the installation groove 10 along the vertical direction, the centering plate 22 can be inserted into the limiting groove 41 more smoothly.

[0047] Specifically, Figure 5 As shown, the top of the centering base column 21 gradually tilts downward from the center to the surrounding areas 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 installation groove 10 along the vertical direction, laying the foundation for the subsequent limiting groove 41 of the steel column foot 4 to be aligned with the centering plate 22.

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

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

[0050] Specifically, Figure 4 As shown, the bottom surface of the steel column foot 4 is provided with a limiting inclined groove 43 connected to the hollow groove, and the limiting inclined groove 43 is connected to the limiting groove 41, and the groove wall surface of the limiting inclined groove 43 is inclined in the direction away from the limiting groove 41. When the centering plate 22 approaches the bottom surface of the steel column foot 4 and is ready to be inserted into the limiting groove 41, it will first contact the inclined groove wall surface of the limiting inclined groove 43, and gradually adjust its position along the guiding direction of the inclined groove wall surface to slide in the direction of the limiting groove 41, so as to accurately extend into the limiting groove 41.

[0051] More specifically, one end of the centering plate 22 facing the notch of the installation groove 10 is provided with a guide slope 221 inclined toward the centering base column 21, and when the centering plate 22 is inserted into the limiting groove 41, the limiting groove 41 slides along the guide slope 221. The setting of the guide slope 221 can guide the steel column foot 4 to an accurate installation position.

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

[0053] Specifically, Figure 4 As shown, there are multiple centering plates 22, and the multiple centering plates 22 are evenly distributed around the centering base column 21. The steel column foot 4 is evenly provided with multiple limiting grooves 41 along the outer wall. The multiple centering plates 22 can be inserted into the multiple limiting grooves 41 one by one. The multiple centering plates 22 are inserted into the multiple limiting grooves 41, which can limit the steel column foot 4 from multiple directions, so that the installation path of the steel column foot 4 in the vertical direction is more accurate, and the steel column foot 4 is effectively prevented from tilting or deflecting during the vertical descent process. In addition, the combination of the evenly distributed centering plates 22 and the limiting grooves 41 enables the steel column foot 4 to evenly distribute the force to each centering plate 22 when subjected to external force, and jointly resist the external force to prevent the steel column foot 4 from tilting or shaking, thereby enhancing the stability of the entire installation structure.

[0054] In this embodiment, the steel column foot 4 is a quadrangular column, and the steel column foot 4 is evenly provided with four limiting grooves 41 along the circumference of the outer wall, and four centering plates 22 are provided, and the four centering plates 22 are evenly distributed around the centering base column 21. The four limiting grooves 41 correspond to the four centering plates 22 one by one, and can achieve 90-degree precise indexing positioning in the circumferential direction, effectively avoiding rotation deviation of the steel column foot 4; and in the vertical direction, the four centering plates 22 strictly constrain the downward movement path of the steel column foot 4, ensuring that it is vertically positioned, greatly improving the accuracy of installation, and reducing the risk of uneven force on the subsequent structure caused by inaccurate positioning.

[0055] In other embodiments, the steel column base 4 may also be a cylinder, and the steel column base 4 is evenly provided with three limit grooves 41 along the circumference of the outer wall, and three centering plates 22 are provided. The three centering plates 22 are evenly distributed around the centering base column 21, and the three limit grooves 41 correspond one-to-one with the three centering plates 22, achieving precise division at equal intervals of 120 degrees in the circumferential direction, effectively constraining the rotational freedom of the column base and preventing it from circumferentially offset.

[0056] The shape of the steel column foot 4 , the number of the middle plate 22 and the limiting grooves 41 are not specifically limited here.

[0057] More specifically, if Figure 5-Figure 6 As shown, corresponding to each centering plate 22, two pressing through holes 211 and two pressing plates 32 are respectively provided, the centering plate 22 is located between the two pressing through holes 211, and the two pressing plates 32 are correspondingly arranged in 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 subjected to force synchronously, and the pressing force is transmitted to the movable plate 33 more evenly, avoiding local deformation of the pressing plate 32 due to excessive force at a single point, ensuring the stability of the force during the transmission process, making the entire locking mechanism 3 run more smoothly and reliably, and laying the foundation for the subsequent accurate locking of the steel column foot 4.

[0058] Specifically, the centering plate 22 is provided with a guide groove 222, and the lower pressing plate 32 is inserted into the guide groove 222 and can move along the guide groove 222. The guide groove 222 provides a precise moving path for the lower pressing plate 32, so that the movement trajectory of the lower pressing plate 32 during the pressing process of the steel column foot 4 is strictly limited, avoiding the connection hole 331, the extension hole 212 and the positioning hole 42 from being misaligned or shaken during the pressing process, further ensuring the coordination 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, there are four centering plates 22 , and guide grooves 222 are provided on two opposite sides of each centering plate 22 . The two lower pressing plates 32 provided corresponding to each centering plate 22 can be inserted into the two guide grooves 222 one by one.

[0060] Specifically, there are multiple connection holes 331, extension holes 212, positioning holes 42, elastic members 34 and locking rods 35, respectively. By pressing down the lower pressing plate 32, multiple connection holes 331, multiple extension holes 212 and multiple positioning holes 42 can correspond to each other and be connected, and multiple elastic members 34 can correspondingly drive multiple locking rods 35 to be correspondingly penetrated in multiple connection holes 331, multiple extension holes 212 and multiple positioning holes 42. Driven by multiple elastic members 34, multiple locking rods 35 are penetrated in corresponding holes at the same time, which not only enhances the connection strength between the steel column foot 4 and the centering mechanism 2, but also provides a full range of vertical constraints for the steel column foot 4, ensuring that the steel column foot 4 always maintains a vertical state.

[0061] In this embodiment, four movable plates 33 are provided. Figure 8 As shown, each two lower pressing plates 32 are connected to a corresponding movable plate 33, and each movable plate 33 is provided with two connecting holes 331 along its length direction, a total of eight connecting holes 331, correspondingly, as shown in FIG. Figure 5 As shown, eight extension holes 212 are also provided, two extension holes 212 form a group, and the four groups of extension holes 212 are evenly distributed around the centering column 21. The two extension holes 212 in each group are distributed along the length direction of the centering column 21 and are located directly above the centering plate 22. Correspondingly, as shown in FIG. Figure 4 As shown, eight positioning holes 42 are also provided, two positioning holes 42 form a group, and the four groups of positioning holes 42 are evenly distributed around the steel column foot 4. The two positioning holes 42 in each group are distributed along the length direction of the steel column foot 4 and are located directly above the limiting groove 41; correspondingly, as shown in FIG. Figure 3 and Figure 6 As shown, eight elastic members 34 are provided, two elastic members 34 form a group, and four groups of elastic members 34 are evenly distributed around the locking base column 31. The two elastic members 34 in each group are distributed along the length direction of the centering base column 21, and each elastic member 34 is connected to a locking rod 35. The arrangement of four independent movable plates 33 means that even if the connecting hole 331 on one movable plate 33 is not connected to the corresponding extension hole 212 and positioning hole 42, it does not affect the connection holes 331 on the other three movable plates 33 being connected to the corresponding extension holes 212 and positioning holes 42. Therefore, this arrangement is more flexible and adaptable, and can better ensure that the steel column foot 4 is fixed in a vertical state.

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

[0063] Specifically, Figure 3 and Figure 7 As shown, the locking mechanism 3 further includes a sleeve 36, which is 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, and effectively prevents the locking rod 35 from shaking or deviating from the predetermined path during the reciprocating movement, ensuring that the locking rod 35 can accurately penetrate the corresponding hole every time, improving the working accuracy of the locking mechanism 3, and ensuring the reliability of the installation of the steel column foot 4.

[0064] More specifically, if Figure 6 As shown, an arc head is provided at one end of the locking rod 35 away from the elastic member 34 to facilitate the locking rod 35 to be inserted into the corresponding hole.

[0065] The present invention also provides an insertion type steel column foot installation method, which adopts the insertion type steel column foot installation 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 move downward along the centering plate 22 to squeeze the lower pressure plate 32 to drive the movable plate 33 to move downward, so that the connecting hole 331, the extension hole 212 and the positioning hole 42 are connected, and the locking rod 35 can be driven by the elastic member 34 to pass through the connecting hole 331, the extension hole 212 and the positioning hole 42 in sequence to fix the steel column foot 4.

[0067] By adopting the above-mentioned installation method, it is only necessary to align the limiting groove 41 of the steel column foot 4 with the centering plate 33 and move it downward. During the downward movement, the steel column foot 4 can automatically trigger the locking mechanism 3 to complete the fixing work. This process does not require manual participation, is simple to operate, and has high assembly efficiency.

[0068] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
