Problems solved by technology
[0004]
1. The connection methods of most of the nodes only adopt the commonly used bolt connection or welding method, and there are few new connection methods. Only the connection nodes cannot guarantee good tightness, safety and stability, etc.;
[0005]
2. The traditional prefabricated column-column vertical connection node is a precast concrete column-column lap joint, and the concrete grouting material is transported through the casing connection. Due to the difference in on-site construction technology, it is prone to the situation that the interior is not filled, and the grouting is dense The situation cannot be observed directly;
[0006]
3. The use of bolt connection requires intensive construction on site, which takes a long time, high labor costs, and high cost. Under the action of large loads, problems such as slippage and large overall deformation are prone to occur, and it is easy to loosen under the action of power, and the bolts are easy to break under fire. Burst, at the same time, the wall of the prefabricated fully decorated building module needs to be remodeled, which is time-consuming and labor-intensive;
[0007]
4. Column-to-column welding needs to transport the welding machine to the installation layer. Due to the difference in on-site construction technology, the welding quality of the weld seam is difficult to guarantee; Concave-convex deformation occurs on the original flat steel plate, and the pre-embedded steel plate and weld seam are prone to corrosion, so protective measures need to be taken, which increases the cost of anti-corrosion treatment

Embodiment Construction
[0031] In modern modular prefabricated buildings, the building is modularized. Each module structure is prefabricated and fully decorated in the factory, and then hoisted on site. The connection between modules is often a difficult point in construction, and the connection between columns The connection is the key part, and it is also the key to the further development of modular buildings. Therefore, how to quickly and firmly connect modules to modules is a technical problem to be solved urgently by those skilled in the art. However, the current solutions are limited. A large number of on-site welding is used to realize the connection between columns. However, there are various defects in the welded joints, and the construction site requires a lot of manpower and material resources. The construction labor cost is high, the difficulty is high, and the efficiency is low, which greatly reduces the modular assembly. The enthusiasm for the development of the modular construction in...

The invention discloses an occlusion type steel-concrete composite column-column connection joint and a manufacturing method thereof. The occlusion type steel-concrete composite column-column connection joint is applied to modularized assembled buildings and comprises at least two box-shaped steel columns to be connected, wherein the two box-shaped steel columns are adjacent to each other and horizontally connected; the face-to-face side surfaces of one box-shaped steel column and the other box-shaped steel column are occluded to allow the two box-shaped steel columns to perform cooperative work; and concrete is poured in the box-shaped steel columns. The connected side surfaces of two adjacent box-shaped steel columns are respectively provided with a snapping plug-in member and / or a snapping groove, and the snapping plug-in member of one box-shaped steel column is inserted into the snapping groove of the other box-shaped steel column so as to the face-to-face surfaces of the two adjacent box-shaped steel columns to be occluded together. The occlusion type steel-concrete composite column-column connection joint provided by the invention is convenient for on-site construction, improves production efficiency of a building, effectively improves the stress behaviors of a modularized assembled column-column connection structure and the seismic performance of a modularized assembledhouse, and enhances the integrity of a structure.
Description
technical field [0001] The invention relates to the technical field of modular prefabricated buildings, in particular to a method that facilitates on-site construction, improves building production efficiency, effectively improves the stress behavior of modular prefabricated column-column connection structures and the seismic performance of modular prefabricated houses, and enhances structural integrity The occlusal steel-concrete composite column-to-column connection node and its fabrication method. Background technique [0002] In the actual construction process of prefabricated buildings, the connection between prefabricated components is often a difficult point in construction, and the hoisting components are not easy to carry out construction positioning, which in turn reduces the construction quality and assembly efficiency. For prefabricated buildings, column-to-column connection is the key to ensuring structural safety; prefabricated components are connected through ...
