[0002] PC components are an important part of prefabricated buildings, covering prefabricated exterior walls, prefabricated interior walls, prefabricated columns, prefabricated beams, prefabricated floor slabs, prefabricated stairs, prefabricated balconies, prefabricated air-conditioning panels, etc. in prefabricated concrete structures.

[0003] At present, bolts are usually used to fix the nodes of PC components. However, bolt connections will produce local stress concentration on the contact surface. In precast concrete parts, these stresses will cause cracks in the concrete to appear and expand, especially in the areas around the joints. In addition, bolt connections need to be accurately installed and tightened during the construction process. Since precast concrete parts are usually heavy and large in size, special tools and equipment are required for installation, which increases the complexity and cost of construction. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides an assembled PC component, which solves the problem that bolt connection may generate local stress concentration on the contact surface, and in the concrete precast parts, these stresses may cause the generation and expansion of concrete cracks.

[0006] T-shaped grooves are provided on the left and right sides of the horizontal plate and the left side of the side plate, and two adjacent T-shaped grooves are combined to form a through hole, and a connecting piece is inserted inside the through hole to connect two adjacent horizontal plates or connect the horizontal plate to the side plate;

[0007] A plurality of positioning rods are arranged on the right side of the transverse plate, and corresponding to the positioning rods, a plurality of positioning holes are opened on the left side of the adjacent transverse plate so that the positioning rods can be inserted into the interior of the adjacent transverse plate.

[0008] Furthermore, the left side of the side plate is provided with a plurality of connection holes for inserting a plurality of positioning rods respectively.

[0009] Furthermore, the through hole is in an I-shape.

[0010] Furthermore, the connecting piece is an I-beam.

[0011] Furthermore, the height of the connecting member is equal to the height of the transverse plate and the side plate.

[0012] Furthermore, a plurality of the positioning rods are symmetrically distributed on the front and rear sides of the T-shaped slot.

[0013] Furthermore, the upper end surfaces of the transverse plate and the side plates are both installed with connecting plates, and corresponding to the connecting plates, connecting ports that are adapted to the connecting plates are opened at the bottoms of the connecting plates and the side plates.

[0014] Furthermore, the shape of the side cross-section of the connecting plate is an isosceles trapezoid.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0016] 1. The assembled PC component is made by inserting the positioning rod into the positioning hole in the adjacent horizontal plate. At this time, the two T-slots are connected to each other, and the connecting piece can be inserted into the inside of the through hole to complete the docking of the two horizontal plates. The two adjacent horizontal plates are docked so that the T-slots inside the two adjacent horizontal plates fit each other, and at the same time ensure that the front and rear sides of the two horizontal plates are located on the same horizontal line, and then the connecting piece is inserted into the inside of the two T-slots to connect the two horizontal plates.
