Problems solved by technology
[0004] In the existing technology, the beam-column joints are generally bound to each other with reserved steel bars, and then connected and fixed by cast-in-place in the later stage. The construction process is complex and the construction period is long, which is difficult to meet the requirements of prefabricated buildings with short construction period and simple assembly.

Embodiment
[0041] A method for connecting an assembled beam and a column with a self-locking structure, such as figure 1 As shown, it is used to connect the prefabricated beam 1 and the column 2. The two ends of the beam 1 are integrally provided with the connecting block 3, and the connecting block 3 is connected to the column 2, so as to realize the fixing and connection between the beam 1 and the column 2. The cross-sectional area of block 3 is the same as that of column 2 . It also includes connection between the connection block 3 and the column 2 using a connection assembly, the connection assembly includes a lower connector 4 embedded in the column 2 and an upper connector embedded in the connection block 3 (not shown in the figure) ), the upper connector and the lower connector 4 are made of steel.
[0042] like Figure 2-4 As shown, the lower connector 4 includes a lower embedded casing 5, which is cylindrical, with an open upper end and a closed lower end. The upper part o...

The invention discloses a connecting method of an assembled cross beam and a stand column with a self-locking structure. An upper connecting piece and a lower connecting piece which are mutually matched to form the self-locking structure are included and are respectively embedded and fixed on a connecting block of the cross beam and the stand column, when the connecting block is in butt joint withthe stand column, the upper connecting piece and the lower connecting piece are mutually inserted to form a limiting structure, and the upper connecting piece and the lower connecting piece are fixedly connected into a whole through a consolidation agent. The vertical limiting function is achieved, meanwhile, high rigidity and deformation resistance are achieved, construction is simple and convenient, and the construction period is short.
Description
technical field [0001] The invention relates to the technical field of prefabricated buildings, in particular to a method for connecting a prefabricated beam and a column with a self-locking structure. Background technique [0002] Prefabricated concrete structures refer to concrete structures assembled by prefabricated concrete components through reliable connection methods, including assembled integral concrete structures, fully assembled concrete structures, etc. In construction engineering, it is referred to as prefabricated building; in structural engineering, it is referred to as prefabricated structure. Prefabricated components refer to concrete components prefabricated in factories or on site, such as beams, slabs, walls, columns, balconies, stairs, canopies, etc. [0003] Traditional housing construction technology has low production efficiency, slow construction speed, long construction period, high material consumption and high labor intensity. These series of co...
