[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 a PC component node connection structure, which solves the problem that bolt connection will generate local stress concentration on the contact surface, and in the concrete precast parts, these stresses will cause the generation and expansion of concrete cracks.
[0005] To achieve the above object, the utility model provides the following technical solution: a PC component node connection structure, comprising at least two PC prefabricated components, both sides of the PC prefabricated components protrude outward to form a protrusion, and the protrusion is integrally formed with at least two protrusions on one side close to the adjacent PC prefabricated component;
[0006] Corresponding to the protrusion, a positioning hole for inserting the protrusion is opened on one side of the PC prefabricated component, so as to be used for butt connection between two adjacent PC prefabricated components;
[0007] A V-shaped groove is formed on one side opposite to the two adjacent protrusions along the Z-axis direction, and the two V-shaped grooves are combined to form a rectangular through hole, and a square tube is inserted into the inside of the rectangular through hole to lock the two protrusions.
[0008] Furthermore, the front and rear sides of two adjacent protrusions fit together.
[0009] Furthermore, the length of the protrusion in the X-axis direction is half of the length of the PC prefabricated component in the X-axis direction.
[0010] Furthermore, the square tube is a stainless steel tube.
[0011] Furthermore, the length of the square tube in the Z-axis direction is equal to the length of the PC prefabricated component in the Z-axis direction.
[0012] Furthermore, at least two positioning bolts are arranged on the upper end surface of the PC prefabricated component along the Z-axis direction, and corresponding to the positioning bolts, at least two connecting ports are opened on the bottom of the PC prefabricated component for docking the upper and lower PC prefabricated components.
[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0014] The PC component node connection structure is achieved by inserting a protrusion on one of the PC prefabricated components into a positioning hole inside an adjacent PC prefabricated component, so that the two protrusions fit each other, and the two protrusions fit respectively with the opposite sides of the two PC prefabricated components. At this time, the two V-grooves coincide with each other, and the two are combined to form a rectangular through hole. At this time, the prefabricated square tube is inserted into the interior of the rectangular through hole, and the two PC prefabricated components can be locked at this time, thereby completing the connection of the two adjacent PC prefabricated components.
