[0002] In the field of construction technology, the development of prefabricated buildings is getting faster and faster. At present, the development level of prefabricated buildings in my country is still relatively low, and the main problem is the poor connectivity of the nodes. When installing adjacent prefabricated components, most of them are connected by grouting, that is, a grouting hole is reserved at the top of the prefabricated component, and a dowel bar is reserved at the bottom of the prefabricated component. After the dowel bar of the upper prefabricated component is inserted into the grouting hole of the lower prefabricated component, grouting is performed in the gap of the grouting hole. After the grout solidifies, the upper and lower prefabricated components are connected into a whole.

[0003] The connection nodes of the existing grouting-connected prefabricated components have the problems of high construction cost, great installation difficulty and long construction period; especially during the assembly of prefabricated columns, temporary support and reinforcement of the upper prefabricated columns are required, which increases the time for lifting and hoisting. Therefore, it is necessary to provide a prefabricated column with a self-fixing device without grouting, which can solve the problems of high construction cost, great installation difficulty and long construction period in the assembly of prefabricated columns in the existing technology.

[0020] When the prefabricated column 4 is manufactured, one end of the embedded connector 1 is embedded in the prefabricated column 4. According to the installation position and assembly requirements of the prefabricated column 4, the embedded connector 1 can be embedded at one end or both ends of the prefabricated column 4. Preferably, the embedded connector 1 can be made of high-strength steel such as I-beams, and the connecting plate 2 can be made of thick steel plates. The specifications of the I-beams and the sizes of the thick steel plates can be adaptively selected according to the cross-sectional size of the prefabricated column 4. The connecting plate 2 is fixed to one end of the embedded connector 1 located outside the prefabricated column 4 by full welding, which can be mass-produced and convenient for assembly construction.

[0021] By aligning and fitting the two connecting plates 2 of the upper and lower prefabricated columns 4, the connection area is large, which facilitates accurate and reliable docking of the upper and lower prefabricated columns 4. Six screw holes can be reserved on the connecting plate 2, and high-strength connecting parts such as high-strength bolts and nuts are used to fix the two connecting plates 2 through the screw holes.

[0022] Preferably, the embedded connecting ribs 3 can be steel bars, and the number of the embedded connecting ribs 3 can be adaptively adjusted according to actual needs. The embedded connecting ribs 3 of the upper and lower prefabricated columns 4 are aligned and butt-jointed to strengthen the connection nodes of the upper and lower prefabricated columns 4. The adjacent prefabricated columns 4 are assembled by using the embedded connectors 1, the connecting plates 2, and a plurality of embedded connecting ribs 3 without grouting, which makes the construction process simpler and more convenient while ensuring the reliability of the connection nodes, and reduces the construction cost.

[0023] Please see attached Figure 1 and attached Figure 2 The embedded connecting piece 1 is coaxially arranged with the prefabricated column 4.

[0024] The coaxially arranged embedded connector 1 can ensure the stability of vertical force transmission between two adjacent prefabricated columns 4 after connection, thereby ensuring the reliability of the grouting-free connection node between the two adjacent prefabricated columns 4 .

If it is necessary to connect a crossbeam at the connection node between two adjacent prefabricated columns 4, a plurality of reinforcing ribs 11 can be used to form a reinforced connection with the crossbeam, thereby improving the connection reliability between the crossbeam and the prefabricated column 4, having good scalability and assembly adaptability, and the reinforcing ribs 11 can be set according to actual needs.

[0031] Please see attached Figure 1 To Attachment Figure 3 , the construction method of the utility model is:

[0032] After the installation of the prefabricated column 4 at the bottom is completed, the prefabricated column 4 at the top is hoisted to the top of the prefabricated column 4 at the bottom, so that the connection plate 2 at the bottom of the prefabricated column 4 at the bottom is aligned with the connection plate 2 at the top of the prefabricated column 4 at the bottom, and the two connection plates 2 are fixedly connected by high-strength connecting parts such as high-strength bolts. At the same time, several embedded connection ribs 3 around the connection plate 2 are butt-jointed by split sleeves or electroslag pressure welding to connect the upper and lower prefabricated columns 4 coaxially.

[0033] By utilizing the vertical connection and force transmission of the embedded connecting bars 1 and the connecting plates 2, as well as the vertical docking and force transmission of a plurality of embedded connecting bars 3, a fixing device provided by the prefabricated column 4 is formed, thereby ensuring the connectivity and bearing capacity of the prefabricated column 4 while eliminating the need for grouting assembly.
