Description

Technical Field

[0001] This utility model relates to the field of steel structure wall technology, and in particular, to a wall-column connection structure. Background Technology

[0002] In the field of steel structure construction, the connection structure of columns is a crucial guarantee for building stability. Traditional wall-column connections often employ methods such as welding and bolting. However, these methods have several drawbacks. For example, welding requires specialized welding equipment and personnel, and the welding process is complex, easily leading to insufficient connection strength due to inconsistent weld quality. While bolting is relatively simple to operate, it requires precise hole alignment during installation, and both methods are cumbersome to install and disassemble, hindering rapid assembly and reuse. Especially in temporary or prefabricated buildings requiring frequent disassembly and reassembly, traditional connection methods struggle to meet the requirements of rapid construction and efficient utilization.

[0008] Furthermore, the limiting pressure block, limiting bottom block, protrusion, clearance notch and groove are evenly arranged in a circular pattern.

[0009] Furthermore, the bottom of the limiting sleeve is provided with a limiting hole, the column body is provided with a mounting block, and the limiting member is a vertical column that is flexibly and movablely mounted on the mounting block.

[0010] Furthermore, the mounting block is provided with a through hole, the vertical column is inserted through the through hole, the upper end of the vertical column is provided with an insertion head, the bottom of the insertion head is provided with a protruding ring, and a spring is sleeved on the vertical column.

[0014] Furthermore, the bottom of the mounting base is provided with an insertion pre-embedded part.

[0015] This utility model has the following beneficial effects:

[0016] The rapid insertion of columns is achieved through the interlocking of the protruding strip at the lower end of the column with the groove of the upper insertion hole, eliminating the need for complex welding or bolting operations.

[0038] Please refer to Figure 1 and Figure 2 A preferred embodiment of the present invention provides a wall-column connection structure, including a column 100, a limiting sleeve 200, and a limiting member 300.

[0039] The columns 100 are arranged vertically. The lower end of the column 100 has a convex strip 110 on its peripheral wall and an insertion hole 120 at its upper end. The peripheral wall of the insertion hole 120 has a groove 121. The bottom of the upper column 100 is inserted into the insertion hole 120 of the lower column 100 and the convex strip 110 is embedded in the groove 121, thereby achieving circumferential positioning.

[0040] The limiting sleeve 200 has a first state and a second state; the limiting sleeve 200 is rotatably fitted onto the column 100 to achieve switching between the first state and the second state. The upper inner ring of the limiting sleeve 200 has an inwardly protruding limiting block 210. In the first state, the limiting block 210 of the limiting sleeve 200 presses down on the upper end of the protruding strip 110, fixing the protruding strip 110 in the groove 121. In the second state, the limiting block 210 of the limiting sleeve 200 is offset from the protruding strip 110 to release the restriction on the protruding strip 110. In the second state, the limiting block 210 is offset from the protruding strip 110, and the protruding strip 110 can be pulled upwards out of the groove 121. The bottom wall of the groove 121 provides support for the protruding strip 110, working in conjunction with the limiting block 210 to achieve vertical fixation.

[0041] The limiting component 300 is installed on the column 100. The limiting component 300 is used to limit the limiting sleeve 200 in the first state, so that the limiting sleeve 200 is kept in the first state, thereby maintaining the vertical limitation of the protrusion 110 and making the splicing connection of adjacent columns 100 stable.

[0042] This utility model provides a wall-column connection structure. By engaging the protrusion 110 at the lower end of the column 100 with the groove 121 of the upper insertion hole 120, a quick connection between columns 100 is achieved, eliminating the need for complex welding or bolt-fitting operations. The rotating design of the limiting sleeve 200 allows it to switch between a first and second state, quickly fixing or releasing the connection of the columns 100, greatly improving installation and disassembly efficiency. It is particularly suitable for temporary or prefabricated buildings requiring frequent assembly and disassembly. In the first state, the limiting sleeve 200's limiting block 210 presses down on the upper end of the protrusion 110, firmly fixing the protrusion 110 within the groove 121, ensuring the stability and reliability of the connection between columns 100. Because this connection structure requires no welding or destructive disassembly, components such as the column 100, limiting sleeve 200, and limiting member 300 can remain intact after disassembly and can be reused multiple times, reducing construction costs.

[0043] Reference Figure 3 In some embodiments of this utility model, the column 100 includes a column body 130 and a column head 140. The column head 140 is connected to the upper end of the column body 130, and a protrusion 110 is provided at the bottom of the column body 130. An insertion hole 120 and a groove 121 extend downward from the upper end face of the column head 140. The diameter of the column head 140 is larger than that of the column body 130, so that the column head 140 partially protrudes from the periphery of the column body 130, and the column head 140 has sufficient size to provide an insertion hole 120 for insertion into the bottom of the column body 130.

[0044] Reference Figure 4 and Figure 8In some embodiments of this utility model, the lower inner ring of the limiting sleeve 200 is provided with an inwardly protruding limiting bottom block 220, and the limiting pressure block 210 and the limiting bottom block 220 are vertically aligned; the outer peripheral wall of the column head 140 is provided with a clearance notch 141 that is offset from the groove 121; the limiting bottom block 220 can vertically pass through the clearance notch 141; when the limiting sleeve 200 is in the first state, the limiting pressure block 210 and the limiting bottom block 220 are both offset from the clearance notch 141, and the upper end surface of the limiting bottom block 220 is in contact with the bottom surface of the column body 130 protruding from the bottom of the column head 140. In the second state, the limiting bottom block 220 is aligned with the clearance notch 141, so that the limiting sleeve 200 can be installed. The limiting bottom block 220 can pass through the clearance notch 141 to pass over the column head 140, so that after subsequent rotation, the upper end surface of the limiting bottom block 220 fits against the bottom surface of the column body 130 protruding from the bottom of the column head 140, thereby achieving vertical fixation of the limiting sleeve 200, and thus achieving vertical fixation of the limiting sleeve 200 on the protrusion 110. During installation, both the limiting block 210 and the limiting bottom block 220 are circumferentially offset from the protruding strip 110. The limiting bottom block 220 is inserted into the clearance notch 141 and moves vertically downwards until the limiting block 210 is flush with the upper surface of the column head 140. At this point, the limiting sleeve 200 is in its second state, with the limiting block 210 and the limiting bottom block 220 aligned with the clearance notch 141 and circumferentially offset from the protruding strip 110. The limiting sleeve 200 can then be rotated until the limiting block 210 and the limiting bottom block 220 are offset from the clearance notch 141, thus allowing the limiting block 210 to move vertically downwards. The bottom surface of the limiting block 220 is in contact with the upper surface of the protruding strip 110, and the upper surface of the limiting block 220 is in contact with the bottom surface of the column head 140 protruding from the column body 130. This achieves the pressing and fixing of the protruding strip 110 by the limiting block 210. In addition, the limiting block 220 restricts the vertical upward movement of the limiting sleeve 200, thus achieving the vertical fixation of the limiting sleeve 200. This allows the upward force of the protruding strip 110 to be transmitted to the column 100 below through the limiting sleeve 200, thereby avoiding the vertical force acting on the limiting member 300, which could cause stress concentration or excessive force at the limiting member 300 and make it prone to damage. Furthermore, the limiting member 300 restricts the rotation of the limiting sleeve 200, thus fixing the positions of the limiting sleeve 200 and the protruding strip 110.

[0045] In some embodiments of this utility model, the limiting pressure block 210, the limiting bottom block 220, the protruding strip 110, the clearance notch 141 and the groove 121 are evenly arranged in a circular pattern to achieve multi-position limiting and improve connection stability.

[0046] Reference Figure 4 and Figure 8In a further embodiment of this utility model, the bottom of the limiting sleeve 200 is provided with a limiting hole 230, the column body 130 is provided with an installation block 150, and the limiting member 300 is a vertical column that is elastically and movably installed on the installation block 150. The upper end of the vertical column can be inserted into the limiting hole 230 to achieve circumferential limiting of the limiting sleeve 200, so that the limiting sleeve 200 cannot rotate and remains in the first state. It is only necessary to pull the vertical column downward so that the upper end of the vertical column is disengaged from the limiting hole 230 to unlock the limiting sleeve 200. The operation is simple and convenient.

[0047] Reference Figure 6 and Figure 7 In a further embodiment of this utility model, the mounting block 150 is provided with a through hole 151, the vertical column is inserted through the through hole 151, the upper end of the vertical column is provided with an insertion head 310, the insertion head 310 is used to insert into the limiting hole 230, the bottom of the insertion head 310 is provided with a protruding ring 320, and a spring 400 is sleeved on the vertical column. The spring 400 is a compression spring and is located between the mounting block 150 and the protruding ring 320 to apply an upward elastic force to the protruding ring 320 and the insertion head 310, so that the insertion head 310 is kept in the state of being inserted into the limiting hole 230, thereby achieving stable limiting.

[0048] Reference Figure 6 and Figure 7 In a further embodiment of this utility model, the mounting block 150 is provided with a connecting block 152, and the connecting block 152 and the column body 130 are provided with corresponding holes for connection and fixation by fasteners, thereby realizing the connection and fixation of the mounting block 150.

[0049] Reference Figure 6 and Figure 7 In a further embodiment of this utility model, a hook 500 is also included; a stud 330 is provided at the lower end of the vertical column through the mounting block 150, and the upper end of the hook 500 is sleeved on the stud 330. A fastening nut 331 is threaded onto the stud 330 to fix the hook 500. During operation, the hook 500 can be pulled to drive the insertion head 310 out of the limiting hole 230, thereby unlocking the limiting sleeve, making the operation more convenient.

[0050] Reference Figure 5 In a further embodiment of this utility model, the column 100 has a central hole 160 at its center. The cross-sectional profile of the central hole 160 is smaller than that of the insertion hole 120. The upper end of the central hole 160 extends to the insertion hole 120, thereby reducing the weight of the column 100 and achieving lightweighting. Furthermore, since the cross-sectional profile of the central hole 160 is smaller than that of the insertion hole 120, a portion of the bottom wall of the insertion hole 120 is left to support the bottom of the upper column 100, thereby improving the stability of the support.

[0051] Reference Figure 3 and 5In a further embodiment of this utility model, the bottom of the lowest column 100 is connected to a mounting base 600, and the top of the mounting base 600 is provided with an insert post 610 for inserting into the center hole 160, thereby improving the installation accuracy and connection tightness of the mounting base 600 and the column 100. The insert post 610 and the column 100 can be fixed by welding or fasteners.

[0052] Reference Figure 3 and 5 In a further embodiment of this utility model, the bottom of the mounting base 600 is provided with an insertion pre-embedded part 620, the bottom of which is pointed to be embedded in the underlying concrete or soil layer. The mounting base 600 is also provided with holes for fixing to the ground by fasteners.

[0053] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
