Bolt steel bar plug pin prefabricated wooden structure column base joint

Abstract

The invention discloses a bolt steel bar plug pin prefabricated wooden structure column base joint, and belongs to the field of constructional engineering. The bolt steel bar plug pin prefabricated wooden structure column base joint comprises a prefabricated wooden structure column, foundation embedded parts, a connecting steel bar, nuts, end nuts and a pin board. Four protruding steps are arranged on the four faces of the bottom of the prefabricated wooden structure column, steel bar holes are reserved in the protruding steps, and pin board grooves are reserved on the rear portions of the protruding steps. Pin boards are inserted in the pin board grooves. Thread holes are formed in the centers of the foundation embedded parts, and the foundation embedded parts are pre-buried in a foundation of a column base and opposite to the reserved steel bar holes. Thread sections are arranged at the two ends of the connecting steel bars and inserted into reserved holes, and the bottoms of the thread sections are screwed into the thread holes of the foundation embedded parts in a threaded mode. The nuts are screwed to the thread sections at the upper ends of the connecting steel bars, and thenuts are closely attached to the protruding steps. The end nuts are screwed to the upper ends of the connecting steel bars and closely inserted to the pin boards. The bolt steel bar plug pin prefabricated wooden structure column base joint is connected by threads and the nuts, in actual installation, the work of screwing bolts and installing the pin boards is only needed, convenience and efficiency are achieved, efficiency is high, the tensile and compressive properties of steel bars can be transmitted, and good structural performance is achieved.

Description

technical field [0001] Bolt reinforcement bolt prefabricated assembly timber structure column foot node. Background technique [0002] The prefabricated wooden structure has reached a higher level of housing in terms of design, material regeneration, low carbon, living comfort, energy saving, and earthquake resistance. The prefabricated wooden structural components are produced in the factory, and then the prefabricated components are transported to construction. , to assemble. This construction method can greatly improve the level of mechanized construction, reduce construction personnel, save construction time, speed up construction progress, and reduce construction costs. The development of prefabricated wood structure is an effective way to realize the industrialization of construction, which can effectively save resources, reduce environmental pollution, and is conducive to improving the modernization level of the national construction industry, and has broad developme...
