Precast concrete member connecting joint and connecting method

Abstract

The invention discloses a precast concrete member connecting joint, and relates to the technical field of building structures. The connecting joint comprises a member body, connecting rods and connecting pieces. The connecting rods are arranged at the ends of the member body respectively. The connecting rods are embedded into the member body in the length direction of the member body. One ends ofthe connecting rods stretch out of the member body, the connecting rods are used for being arranged on a supporting member, and the connecting pieces are embedded into the member body side by side inthe length direction of the member body. One ends of the connecting pieces are fixedly connected to the connecting rods. The invention further discloses a precast concrete member end connecting method. The method comprises the steps that the portions, stretching out of the member body, of the connecting rods are embedded into concrete; the supporting member needs to supply a supporting portion with enough strength to be connected with the precast concrete member to be flat, and the connecting rods stretching out of the member body are placed on the supporting portion of the supporting member.According to the technical scheme, the ends of the precast concrete member are connected firmly, and construction is convenient.

Description

technical field [0001] The invention relates to the technical field of building structures, in particular to a connection node of a prefabricated concrete component and a connection method thereof. Background technique [0002] In recent years, with the gradual disappearance of my country's demographic dividend and the rapid increase in labor costs, under the encouragement of national and local policies, construction industrialization has become the focus of industry development. Prefabricated concrete structures, as the main means of realizing construction industrialization, have been recognized by the industry. High attention, ushered in a new wave of development. Prefabricated buildings are concrete structures assembled by prefabricated concrete components through reliable connections, including assembled integral concrete structures, fully assembled concrete structures, etc. The road to the development of construction industrialization based on prefabricated concrete str...

Problems solved by technology

Because the diameter of the reinforced steel bars of the frame beams and columns is generally large, it will cause too much staggered steel bars in the joints, making it difficult to pour concrete, and it is difficult to ensure that the concrete is dense during construction, resulting in a decline in construction quality. In addition, steel bars from different directions in the joint area are prone to collision , resulting in difficulties in construction, which requires designers to accurately locate the arrangement of steel bars, increasing the difficulty
