[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. Modular column base connection components are one of the key core technologies for achieving rapid installation, precise positioning and efficient force transmission of buildings. It represents the modernization and industrialization upgrade of traditional column base nodes, aiming to minimize on-site wet work and improve construction speed and quality stability.

[0003] However, when connecting modular column bases now, most of them are directly limited by fixing bolts to limit the edges. This means that when the connection is subjected to force, it can only bear the force through the edges. During long-term use, the connection points are prone to damage due to the single force position and uneven force distribution, which can lead to structural abnormalities and affect the stability and service life of the work. Utility Model Content

[0031] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0032] Example: Figure 1-4As shown, this utility model provides a technical solution: a modular column base connection component for steel structure prefabricated buildings, including a fixed operating column 1, and a combination component 2 is provided on the side end of the fixed operating column 1.

[0033] The assembly 2 includes a fixed limiting box 201, clamping bolts 202, an internal pressure clamping frame 203, limiting bolts 204, limiting nuts 205, an insertion locking block 206, a movable operating port 207, and an insertion limiting hole 208;

[0034] A fixed limit box 201 is sleeved at the bottom of the fixed operating column 1. A clamping bolt 202 is symmetrically rotatably connected to the inside of the fixed limit box 201. An internal pressure clamping frame 203 is connected to the side of the clamping bolt 202 through a screw seat. There are two internal pressure clamping frames 203. The internal pressure clamping frames 203 are slidably installed inside the fixed limit box 201. The bottom of the internal pressure clamping frame 203 is in contact with the bottom of the fixed operating column 1 to achieve stable combination support and ensure the stability of overall positioning restriction and snap-fit ​​limit.

[0035] Several limiting bolts 204 are welded at equal intervals on the bottom inner side of the fixed limiting box 201. The side ends of the limiting bolts 204 are fitted with the side ends of the fixed operating column 1 to achieve side end support clamping and support fixation. The side ends of the limiting bolts 204 are connected to the limiting nuts 205 by threads. The bottom end of the limiting nuts 205 is in contact with the top end of the inner pressure clamping frame 203 to ensure the stability of the limiting clamping and limiting fixation.

[0036] The internal pressure clamping frame 203 has an insertion locking block 206 symmetrically welded to one end. The bottom end of the fixed operating column 1 has several movable operating ports 207 equidistantly opened. The fixed operating column 1 has insertion limiting holes 208 symmetrically opened at both ends. The insertion locking block 206 is embedded and installed inside the insertion limiting hole 208 to realize the alignment and insertion limiting, and ensure the stability of the support positioning and support fixation.

[0037] A limit component 3 is provided on the side end of the fixed limit box 201;

[0038] The limiting component 3 includes an operating limiting post 301, a combined threaded hole 302, a connecting bolt 303, a closing limiting cover 304, and a protruding clamping block 305;

[0039] The fixed limit box 201 is symmetrically equipped with operation limit posts 301, and one end of the operation limit post 301 is provided with a combined threaded hole 302.

[0040] Both ends of the fixed operating column 1 are rotatably connected by connecting bolts 303. The connecting bolts 303 are combined with the operating limit column 301 through the combined threaded hole 302 to ensure the stability of the overall connection restriction and overall fixation.

[0041] The top of the fixed limiting box 201 is symmetrically hinged with a closed limiting cover 304. The side end of the closed limiting cover 304 is attached to the side end of the fixed operating column 1 to achieve top support and protection. Several protruding clamping blocks 305 are welded at equal intervals on the side end of the fixed limiting box 201.

[0042] The working principle and usage process of this utility model are as follows: When installing and fixing the column base, the operator inserts the fixing operation column 1 into the inner side of the fixing limit box 201. At this time, the fixing operation column 1 moves along the fixing limit box 201, and multiple sets of limit bolts 204 are fitted and connected to the fixing operation column 1. At this time, the limit bolts 204 pass through the moving operation port 207 through the fixing operation column 1, so that when the fixing operation column 1 moves down, it will not affect it. After the fitting is completed, by rotating the clamping bolt 202, the clamping bolt 202 drives the inner pressure clamping frame 203 to move along the fixing limit box 201. The position box 201 moves, pushing the internal pressure clamping frame 203 to the top of the fixed operating column 1 and the side of the limiting bolt 204, so that the insertion locking block 206 moves along the fixed operating column 1 and is embedded into the inside of the insertion limiting hole 208, thereby clamping and limiting the fixed operating column 1, increasing its contact area. After clamping and fixing, the limiting nut 205 and the limiting bolt 204 are combined by threads to clamp and fix the internal pressure clamping frame 203 and the fixed operating column 1, further improving the fixing effect and ensuring the stability of the connection.

[0043] After the fixed operating column 1 is engaged and fixed, push the connecting bolt 303 along the fixed operating column 1 to push the connecting bolt 303 into the inner side of the combined threaded hole 302. The connecting bolt 303 is combined with the operating limit column 301 through the thread to realize the clamping and fixing of the side end of the fixed operating column 1, ensuring the stability of its side limiting fixation. After the fixation is completed, rotate and close the limit cover 304 to isolate and restrict the inside, avoid the subsequent filling concrete and soil from corroding the connection, and prevent the connection point from being rusted and damaged, thus extending the service life of the combined fixation. The protruding clamping block 305 increases the contact area between the fixed limit box 201 and the fixed point, improves its stress strength, and ensures the stability of its stress contact.

[0044] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
