The beneficial effects of the application are as follows:
1. the splice plate and the tail plate are connected by using a connecting structure, and the splice plate and the tail plate can be respectively prefabricated at the ends of the prefabricated column or the prefabricated wallboard. The two prefabricated components connected through the connecting piece can be connected after being inserted and locked through the bolt, so that the connection construction is more convenient.
2. When the plugboard is connected with the tail board, the end part of the plugboard at the interval between the adjacent plugboards is abutted with the notch drawknot body. At the moment, the notch drawknot body can limit the depth and the position of the inserting plate inserted into the clamping groove, so that the plug preformed holes correspond to the inner side plate preformed holes and the outer side plate preformed holes, and a connecting channel into which the plug can be inserted is formed; on the other hand, the notch drawknot body is used for blocking and restraining the plugboard, so that when the connecting structure connects two prefabricated columns or prefabricated wallboards, and when the ends of the two prefabricated columns or prefabricated wallboards to be connected are not injected or the injection is not strong, the mutual abutting of the notch drawknot body and the plugboard can form the compression bearing capacity of the abutting structure for resisting axial load.
3. After the bolt is inserted into the connecting channel and respectively abutted with the inner walls of the reserved holes of the outer side plate and the reserved holes of the plug connector, the bolt limits the separation movement of the plug plate and the tail plate.

The pressing force is eccentric pressure to the side plates, and can cause the outer side plates to expand outwards and bend, so that the tension bearing capacity of the connecting piece is greatly reduced. The notch drawknot body arranged at the connecting end of the side plate can effectively restrict the lateral deformation of the inner side plate and the outer side plate, so that the tension bearing capacity of the connecting piece can be greatly improved.
4. Because of unavoidable processing of the connecting piece and installation errors between the connecting piece and the prefabricated component, the positions of the bolts are uncertain when the bolts are abutted against the inner walls of the reserved holes of the side plates and the reserved holes of the plug connectors, so that after the bolts are abutted against the inner walls of the reserved holes of the side plates and the reserved holes of the plug connectors, enough contact length between the bolts and the inner and outer side plates of the connecting structure is needed to provide enough tensile bearing capacity, and therefore enough travel space is needed to be provided for the bolts on the connecting side plates. The bolt can move due to the structures of the outside threaded holes of the outer side plates, the side expansion nuts and the reserved holes of the inner side plates, and enough movement stroke space is not provided by the bolt, so that the influence of processing and installation errors on connection of the connecting piece is eliminated.
5. When the slope surface of the bolt is arranged on the side surface opposite to the opening end of the clamping groove and the slope surface of the corresponding plug connector preformed hole is correspondingly matched, the slope surface of the bolt and the slope surface of the plug connector preformed hole are mutually abutted to form the bearing capacity of the connecting piece when resisting the axial tension load; the slope surface of the bolt is arranged on one of two side surfaces perpendicular to the opening end surface of the clamping groove, the slope surface of the corresponding plug preformed hole is correspondingly matched, and the slope surface of the bolt and the slope surface of the plug preformed hole are mutually abutted at the moment to form the shearing bearing capacity of the connecting piece for resisting shearing load perpendicular to the axial direction. Therefore, the notch drawknot body and the bolts with different inclined surfaces facing to the different directions limit the plugboard, the inner side plate and the outer side plate completely, and each connecting piece corresponds to the reinforcing steel bar on one side of the column or the wall, so that the connecting piece has the equal strong connecting effect with the reinforcing steel bars in the cast-in-situ reinforced concrete column or the wall. In conclusion, the connecting piece has compression resistance, tensile resistance and shearing resistance, so that the slurry poured at the joint does not need to be waited for reaching strength, and continuous installation and construction can be carried out without a supporting template, thereby improving the installation and construction efficiency and reducing the engineering cost.

When the latch 41 stops moving, the front and rear ends thereof need to be maintained in sufficient contact with the outer and inner plate pre-grooves 311 and 321 to provide tensile load-bearing capacity, so that the outer and inner plates 31 and 32 need to provide sufficient front and rear stroke space for the latch 1. Therefore, when the bolt 41 is in certain machining errors and installation errors, the bolt can also have enough contact length and area with the reserved hole wall of the side plate, and the connecting piece can also have enough bearing capacity.
The connecting piece has compression resistance, compression resistance and shearing resistance, so the prefabricated column or the prefabricated wallboard with the connecting piece is fixedly arranged at the end part, and the continuous installation and construction can be realized when the end part of the prefabricated component is not grouted or grouting does not reach the strength. Because each connecting piece corresponds to the reinforcing steel bar on one side in the column or the wall, the connecting piece has a strong connecting effect with the cast-in-situ reinforced concrete column or the wall.

When the building connecting piece is applied to the connection of the prefabricated columns, the reserved grouting holes 14 are arranged, and grouting or concrete pouring can be carried out through the reserved grouting holes 14, so that the permanent compression bearing capacity of the prefabricated components is improved. When the connecting pieces are used for connecting the prefabricated columns, after the four connecting pieces are spliced according to the splicing grooves, the inserting plates 1 in the four connecting pieces are welded at the abutting positions through the grooves of the inserting plate grooves 16 and the tail connecting plate grooves 26, so that the connecting pieces are connected into a whole. The strength of the connecting piece is improved, and the relative position relation of the connecting pieces can be fixed through welding connection, so that the inserting connection of the connecting piece cannot be affected due to the installation error between the connecting piece and the prefabricated part after the connecting piece is fixed at the end part of the concrete member.
