Example Embodiment

[0023] A prefabricated superimposed primary and secondary beam connector of the present invention mainly includes a supporting end arranged on the upper surface of the prefabricated part of the main beam and covered by the main beam superimposed part 1, prefabricated in the prefabricated part of the secondary beam and superimposed by the secondary beam Partially covered prefabricated end 2, connecting support end and prefabricated end, and the connection part 3 covered by the overlapping part of the secondary beam.

[0024] See Figure 1 to Figure 4 In the preferred embodiment of the invention, the prefabricated superimposed primary and secondary beam connectors are formed by connecting two parallel rectangular-like steel plates. The horizontal side of the two parallel rectangular-like steel plates is the supporting end 1, and the vertical side is prefabricated. At the end 2, the flat structure connecting the horizontal side and the vertical side is the connecting portion 3. The ...

Abstract

The invention provides a prefabricated superposed primary and secondary beam connecting piece. The prefabricated composite primary and secondary beam connecting piece comprises a supporting end, a prefabricated end and a connecting portion, wherein the supporting end is arranged on the upper surface of the prefabricated portion of a primary beam and is wrapped in the superposed portion of the primary beam, the prefabricated end is prefabricated on the prefabricated portion of a secondary beam and wrapped in the superposed portion of the secondary beam, the supporting end and the prefabricated end are connected through the connecting portion, and the connecting portion is wrapped in the superposed portion of the secondary beam. After concrete pouring of a primary and secondary beam superposed layer is completed, a firm whole of the primary beam and the secondary beam is formed. The combination strength between the connecting piece and the beams is high, and the tensile strength is high. In addition, the invention provides a prefabricated superposed primary and secondary beam connecting structure using the prefabricated superposed primary and secondary beam connecting piece, the prefabricated superposed primary and secondary beam connecting structure is high in structural strength and tensile strength, the prefabricated superposed primary and secondary beam is prevented from generating oblique cracks, and the loading capacity and the construction quality are improved.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a connection structure of prefabricated laminated primary and secondary beams and a special connecting piece thereof. Background technique [0002] In the prior art, the connecting piece used for the connection of prefabricated laminated primary and secondary beams is a blind corbel, which is composed of two parallel rectangular steel plates connected, and pads are welded at the bottom of both ends of the rectangular steel plates. The outer side is also welded with steel bars protruding downwards, and the steel bars are anchored in the prefabricated composite secondary beams. As the connector of the prefabricated laminated primary and secondary beams, the dark corbel has low bonding strength with the beam and poor pull-out resistance; and the steel bars are fixed on the outside of the steel plate by welding, which has certain quality risks. [0003] The connecti...
