Description

Technical Field

[0001] This utility model relates to the field of prefabricated building steel structure components, specifically to a prefabricated building steel connector. Background Technology

[0002] Standardized steel components, because steel is recyclable and meets the requirements of sustainable development, and steel structures have good toughness and ductility, which can effectively resist seismic forces. Prefabricated steel connectors are manufactured in factories and then transported to the construction site for rapid assembly. The main advantages of this method include shortening the construction cycle, improving construction accuracy, and reducing the complexity of on-site construction.

[0003] The existing technology has the following shortcomings: the construction of prefabricated building steel structure components is usually quite complex, and most steel connectors are not designed with assembly positioning mechanisms to accurately limit the positioning holes. This design defect may lead to installation deviations or improper connections by workers during construction, thereby increasing safety hazards and potentially causing the steel structure frame to collapse. Therefore, optimizing the assembly positioning mechanism and installation method of prefabricated building steel connectors is crucial to ensuring building safety.

[0004] Therefore, it is necessary to invent a prefabricated steel structure component for buildings. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated building steel connecting structure, including beams, columns, crossbeams, and connectors. The beams are installed through the connectors. The connectors have several first slots on their inner side. The crossbeams are inserted into the first slots on the inner side of the connectors. The first slots are tightly fitted with the insertion end of the crossbeams. A slot sleeve is fixedly installed on the upper end of the connectors. A second slot is provided on the inner side of the slot sleeve. A vertical beam is inserted into the second slot. The second slot is tightly fitted with the insertion end of the vertical beam.

[0006] Preferably, a plurality of support plates are provided at the angle between the lower end of the connector and the beam and column. The upper end of the support plate is fixedly connected to the lower end of the connector by a first bolt. The lower end of the support plate is connected to a fixing plate on the beam and column. The fixing plate is fixedly installed on the beam and column by a plurality of first bolts.

[0007] Preferably, four limiting plates are fixedly installed between the connector and the slot sleeve, and a gap is provided between the four limiting plates.

[0008] Preferably, the vertical beam insertion end is provided with a third bolt hole, the third bolt is inserted into the third bolt hole, the third bolt passes through the slot sleeve, and one end of the third bolt is provided with a fastening bolt.

[0009] Preferably, the crossbeam insertion end is provided with a second bolt hole, the crossbeam is inserted and installed in a first slot, a first bolt hole is provided above the first slot, a second bolt is inserted into the first bolt hole, and the second bolt passes through the first bolt hole and is inserted into the second bolt hole.

[0010] The beneficial effects of this utility model are as follows: In the steel structure components of prefabricated buildings, slots are provided on the connectors, and bolt holes are provided at the upper end of the slots. Bolt holes are also provided at the insertion end of the steel beams. When assembling the steel beams, workers insert the insertion end of the steel beams into the slots and tighten the bolts through the bolt holes to firmly fix the steel beams in the slots. To prevent the bolts from being turned crooked, left and right limiting plates are also added to the design. This design effectively solves the problem of installation deviation or improper connection that may occur during construction and greatly reduces the risk of the steel structure frame collapsing due to installation deviation. It also optimizes the positioning and installation methods of steel connectors in prefabricated buildings. Attached Figure Description
