Embodiment Construction

[0023] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0024] Such as figure 1 As shown, a prefabricated concrete primary and secondary beam connection structure includes a prefabricated main beam 1 and a prefabricated secondary beam 2. A post-casting section 3 is set at the place where the prefabricated main beam 1 overlaps the prefabricated secondary beam 2, and the main beam of the prefabricated main beam 1 The reinforced steel bars at the bottom are continuous in the post-casting section 3, the main beam stirrups 5 are reserved in the post-casting section 3 of the prefabricated main beam 1, the prefabricated secondary beam 2 extends into the post-casting section 3 of the prefabricated main beam 1, and the pref...

Abstract

The invention discloses a prefabricated concrete main beam and secondary beam connecting structure and a construction method thereof. The prefabricated concrete main beam and secondary beam connecting structure comprises a prefabricated main beam and a prefabricated secondary beam, wherein a post-cast section is arranged on the prefabricated main beam; load-bearing bars on the bottom of the prefabricated main beam can continuously penetrate in the post-cast section; main beam stirrups are reserved in the post-cast section of the prefabricated main beam; the prefabricated secondary beam extends into the post-cast section of the prefabricated main beam; longitudinal bars on the prefabricated secondary beam are directly anchored on the prefabricated main beam or are anchored on the prefabricated main beam through additional reinforcements; continuous load-bearing bars are paved in a laminating layer on the upper portion of the prefabricated main beam and penetrate in the upper portion of the prefabricated secondary beam; and the post-cast section is formed by a formwork in a pouring manner. Compared with the prior art, the prefabricated concrete main beam and secondary beam connecting structure has the advantages that a prefabricated main beam and prefabricated secondary beam connection mode is modified so as to facilitate hoisting and connection of prefabricated components, the connection performance of the prefabricated main beam and the prefabricated secondary beam is equal to the effect of a cast-in-place structure, joints are connected to one another firmly, horizontal sleeve grouting connection is not required, materials are saved, the manufacturing cost is reduced, and the prefabricated concrete main beam and secondary beam connecting structure is quick and easy to construct.

Description

technical field [0001] The invention belongs to the field of civil engineering, and relates to a prefabricated concrete primary and secondary beam connection structure and a construction method thereof. Background technique [0002] The key to the prefabricated integral frame structure is how to effectively connect the prefabricated components made in the factory to form an overall structural system after being hoisted on site. The ease of installation and the quality of concrete pouring in the connection node area will directly affect the construction progress and quality of the project. Therefore, on the premise of ensuring the safety of the structure, it is an urgent problem to be solved in the engineering field to find a connection method of the prefabricated monolithic frame that is as simple as possible. [0003] The precast concrete primary and secondary beams can be connected by grouting sleeves horizontally connecting stressed steel bars and other connection method...
