Problems solved by technology

With this type of connection, the workload of binding or welding the joint steel bars between prefabricated beams and prefabricated columns is very heavy, and the quality of the connection is not easy to guarantee, which may easily lead to improper or missing connections at the lap joints.
Because of the lack of simple, effective, and reliable mechanical connection structures to connect prefabricated beams and prefabricated columns, in order to ensure the overall structural strength of prefabricated buildings, beams and columns are still commonly used in cast-in-place construction during construction, which leads to The assembly rate of prefabricated buildings is low and the construction period is long

Embodiment 1

[0089] Such as figure 1 As shown, the connection structure between the prefabricated beam and the prefabricated column provided in this embodiment includes the lower prefabricated column 2, the first prefabricated beam 3, several connectors 7 and several extension rods 8, the connector 7 has a connector body, and the connector The body is provided with more than two connection ends, and the connector 7 is placed in the connection space formed by the combination of the lower prefabricated column 2 and the first prefabricated beam 3, and several stress tendons ( not shown in the figure), these stress tendons are exposed toward the end of the connecting space, and the extension rods 8 correspond to the stress tendons one by one, and the two ends of each extension rod 8 are respectively connected to the corresponding connector 7 and the corresponding Stress tendons connect the lower prefabricated column 2 with the first prefabricated beam 3, and the connecting space is filled with...

Embodiment 2

[0105] Such as Figure 19 with Figure 20 As shown, the connection structure between the prefabricated beam and the prefabricated column provided in this embodiment is basically the same as the connection structure between the prefabricated beam and the prefabricated column provided in Example 1, and will not be repeated here. The difference is that in this embodiment The inner threaded end provided at one end of the stress rib 9 is a connecting nut 12, one end of the connecting nut 12 is provided with a threaded hole, the extension rod 8 is screwed with the connecting nut 12, and the center of the end of the connecting nut 12 away from the threaded hole is provided with an internal large There is a small stepped hole on the outside and a clamping platform 13 is formed around the stepped hole, and the clamping platform 13 of the connecting nut 12 is clamped with the header 14 at the connecting end of the stress rib 9 . The inner threaded end is a connecting nut 12, and the ce...

Embodiment 3

[0107] Such as Figure 21 with Figure 22 As shown, the connection structure between the prefabricated beam and the prefabricated column provided in this embodiment is basically the same as the connection structure between the prefabricated beam and the prefabricated column provided in Example 1, and will not be repeated here. The difference is that in this embodiment , the inner threaded end provided at one end of the stressed rib 9 is a straight threaded sleeve 15, one end of the extension rod 8 is screwed with one end of the straight threaded sleeve 15, and the other end of the straight threaded sleeve 15 is connected with the screw at one end of the stressed rib 9. The column phase is screwed. The stud at one end of the tendon 9 stretches out of the prefabricated beam or the prefabricated column. The inner threaded end is a straight threaded sleeve 15, one end of the extension rod 8 is screwed to one end of the straight threaded sleeve 15, and the other end of the straig...

Abstract

The invention discloses a connecting structure of a prefabricated building. The connecting structure comprises a transverse prefabricated part with the end exposed out of a stress rib, a vertical prefabricated part located below the transverse prefabricated part and with the end exposed out of a stress rib, and a plurality of connectors. One end of the transverse prefabricated part is close to thevertical prefabricated part to form a connecting space, and the connectors are arranged in the connecting space. Each connector is connected with one stress rib in the vertical prefabricated part andone stress rib in the transverse prefabricated part; or, at least one connector is connected with one or more adjacent connectors, one part of the multiple connected connectors is connected with onecorresponding stress rib in the vertical prefabricated part, and the other part of the multiple connected connectors is connected with one corresponding stress rib in the transverse prefabricated part. The connecting structure of the prefabricated building has the advantages that rapid, simple and convenient rigid connection of the transverse prefabricated part and the vertical prefabricated partis achieved, and connection is firm and reliable.

Description

technical field [0001] The invention belongs to the technical field of prefabricated buildings, and in particular relates to a connection structure of prefabricated buildings. Background technique [0002] Prefabricated buildings have the advantages of high industrialization level, fast construction, reduced construction noise, and reduced construction procedures. It is conducive to reducing material consumption, saving a lot of manual labor, improving production efficiency, reducing costs, and is conducive to environmental protection. Prefabricated buildings are modern Trends in the construction industry. [0003] The prefabricated components of prefabricated buildings are generally produced in factories, which is easy to carry out quality control. During construction, the prefabricated components are transported to the construction site for assembly, and concrete is poured at the joints to achieve reliable structural connections. The connection between prefabricated compo...
