Embodiment 1

[0076] Such as Figure 4-22 As shown, a prefabricated column and prefabricated beam connecting structure of a prefabricated building frame structure of the present invention includes a prefabricated column 1 and a prefabricated beam 2. The prefabricated column 1 and the prefabricated beam 2 are made of reinforced concrete, and the prefabricated column 1 is surrounded by There is at least one dark corbel section 3, the precast column 1 and the dark corbel section 3 are cast in one piece, such as Figure 6-8 As shown, the prefabricated column 1 surrounds the four dark corbel sections 3 as a prefabricated center column, which is arranged on the frame (such as Picture 10 As shown in the middle part, the prefabricated column 1 surrounds the three dark corbel sections 3 is a prefabricated side column, which is set in the frame (such as Picture 10 (Shown), the prefabricated column 1 surrounds the two dark corbel sections 3 is a prefabricated corner column, set in the frame (such as Pi...

Embodiment 2

[0086] Such as Figure 4-22 As shown, the present invention is a prefabricated column and prefabricated beam connection structure of a prefabricated building frame structure. The prefabricated column 1 is embedded with prefabricated column reinforcing ribs 22, and at least one end of the prefabricated column 1 is provided with a prefabricated Column steel plate 23, the prefabricated column steel plate 23 is connected to the prefabricated column reinforcement 22, and connecting through holes 24 are evenly distributed on the ring surface of the prefabricated column steel plate 23. Bolt connection installation groove 25. When two prefabricated columns 1 need to be connected, after the prefabricated column steel plates 23 at the ends of the two prefabricated columns 1 are connected, they are installed in the connecting through holes 24 through bolts 26 to realize the connection of the two prefabricated columns 1 connection. After the installation and connection are completed, the b...

Embodiment 3

[0088] Such as Figure 4-22 As shown, a method for connecting prefabricated columns and prefabricated beams of a prefabricated building frame structure of the present invention includes the steps:

[0089] The prefabricated component composed of the prefabricated column 1 and the dark corbel section 3 is integrally poured in the prefabricated component factory, and the prefabricated column 1 and the dark corbel section 3 are integrally poured;

[0090] Pouring the precast beam 2; the precast beam 2 is lapped on the precast beam lap joint 5 of the dark corbel section 3 on the two precast columns 1 through the corbel section lap joints 8 at both ends, and the corbel section lap joint 8 is overlapped with the precast beam After the joint 5 is lapped, the corbel connecting steel plate 9 on the corbel section lap joint 8 is connected with the precast beam connecting steel plate 6 on the precast beam lap joint 5.

[0091] The pouring of the dark corbel section includes the following steps:...

Abstract

The invention discloses a connecting structure and method for prefabricated columns and prefabricated beams of a fabricated building frame structure. The connecting structure comprises the prefabricated columns and the prefabricated beams. At least one hidden bracket section is arranged on each prefabricated column in an embracing mode, and each hidden bracket section is internally provided with abracket longitudinal reinforcing rib. A prefabricated beam lap joint is arranged at the outer end of each hidden bracket section, and prefabricated beam connecting steel plates are pre-buried in theupper end faces and the lower end faces of the prefabricated beam lap joints correspondingly. The prefabricated beam connecting steel plates and the bracket longitudinal reinforcing ribs are connected. Prefabricated beam longitudinal reinforcing ribs are arranged in the prefabricated beams, and the two ends of the prefabricated beams are provided with bracket section lap joints matched with the prefabricated beam lap joints correspondingly. Bracket connecting steel plates are pre-buried in the upper end faces and the lower end faces of the bracket section lap joints correspondingly. The bracket connecting steel plates are connected with the prefabricated beam longitudinal reinforcing ribs. Each prefabricated beam is connected to the prefabricated beam lap joints of the hidden bracket sections on the two corresponding prefabricated columns in a lap-joint mode correspondingly, and the bracket connecting steel plates on the bracket section lap joints and the prefabricated beam connectingsteel plates on the prefabricated beam lap joints are connected.

Description

Technical field [0001] The invention relates to the technical field of construction engineering, in particular to a prefabricated column and prefabricated beam connection structure and a method for a fabricated building frame structure. Background technique [0002] The construction industry is a pillar industry that drives my country's economic development. According to statistics from the Ministry of Housing and Urban-Rural Development: Since 2009, the added value of the construction industry has always maintained above 6.5% of GDP. In recent years, the country has strategically determined to promote the development of construction industrialization and has successively issued a series of policy documents. [0003] At present, the level of industrialization of construction in developed countries in the world is relatively high. For example, the industrialization of construction in Europe and the United States reaches 75%, Sweden is as high as 80%, and Japan can reach 70%. my coun...
