Description

Technical Field

[0001] The utility model belongs to the technical field of prefabricated buildings, and more specifically, particularly relates to a prefabricated building structure. Background Art

[0002] Prefabricated building structures refer to buildings that are manufactured in factories or other manufacturing sites and transported to the intended destination after completion. After the prefabricated components are completed, they will be transported to the construction site and finally assembled and installed through hoisting, splicing, etc. In order to improve construction efficiency and shorten construction period, many existing small buildings generally use prefabricated pile foundations. When constructing prefabricated pile foundations, it is necessary to excavate the foundation pit, level the bottom of the foundation pit with mortar, and finally hoist the prefabricated pile foundation.

[0003] The existing application number is: CN202220131735.8. The utility model disclosed in the utility model belongs to the field of pile foundation node technology, specifically a prefabricated building structure combined pile foundation node structure, including a base and a positioning component, a plurality of through holes are equidistantly arranged in a rectangular shape on the base, the positioning component includes a prefabricated pile connected to the through hole, a connecting shaft rod is arranged in the prefabricated pile, the top end of the connecting shaft rod extends to the top of the prefabricated pile, and a cone head is integrally formed at the bottom end of the prefabricated pile. By reserving large and small holes on the through hole, the disadvantage that the bonding surface of the new and old concrete of the hole is consistent with the punching direction of the pile top is avoided, the connection strength between the cap and the pile foundation is enhanced, and when the base is connected to the pile foundation, the pile foundation will not be unable to be inserted into the reserved hole due to the offset design position. At the same time, the movable seat cooperates with the connecting shaft rod, and by rotating the connecting shaft rod, the movable seat makes a linear reciprocating motion from the connecting shaft rod, so that the other end of the anti-detachment claw makes an outward expansion motion, is embedded in the ground and tightly grips the ground, and the connection stability is increased.

[0004] Based on the above, the existing prefabricated pile foundations are generally pre-buried with anchor bolts at the top of the piles. Since buildings generally need to install multiple sets of prefabricated pile foundations, when the pile foundations are placed on site, cement and the like on the construction site are easily splashed onto the periphery of the anchor bolts, causing the threads to be contaminated, affecting the subsequent installation of the prefabricated pillars.
