Node structure of sinking prefabricated plate and H-shaped steel beam

Abstract

The invention belongs to the field of prefabricated construction, and relates to a connection node structure of a sinking prefabricated plate and an H-shaped steel beam. The plate top of a beam and plate connecting part is pre-embedded with a connecting member. The connecting member is composed of a connecting steel plate and a W-shaped steel bar. A single row of bolt holes are reserved in an outer extending section of the connecting steel plate. The W-shaped steel bar is welded to the bottom of the connecting steel plate. A single row of bolt holes are reserved in an upper flange of the H-shaped steel beam. Bolts pass through the upper flange of the steel beam and the connecting steel plate in sequence. The lower end of each bolt is welded firmly with the bottom of the upper flange of thesteel beam. The upper end of each bolt is fixed through a nut. A load on the prefabricated plate is transferred onto the steel beam through the W-shaped steel bar and the connecting steel plate, andthe path of the transferring force is clear. The W-shaped steel bar, the connecting steel plate and the bolts have good strength and rigidity so that the beam and plate connection are safe and reliable. The plate top of the prefabricated plate is flush with the top of the steel beam, the total height of the beam and plate is low, and the indoor height is increased. The beam and plate are connectedthrough the bolts, the on-site welding is avoided, and the assembly efficiency is increased.

Description

technical field [0001] The invention belongs to the field of prefabricated buildings and relates to a node structure for connecting sunken prefabricated panels and H-shaped steel beams. Background technique [0002] The prefabricated building is a building assembled from prefabricated parts on the construction site. The prefabricated parts are produced and processed in the workshop, and the on-site construction adopts assembly operations, which greatly reduces the cast-in-place operations. Prefabricated buildings have the characteristics of standardization of design and informatization of management. The more standardized the components, the higher the production efficiency, and the lower the cost of the corresponding components. With the digital management of the factory, the cost performance of the entire prefabricated building is very high. Now the country is actively promoting the reform of supply structure and the development of new urbanization, and vigorously developi...

AI Technical Summary

Problems solved by technology

The total height of the beams and slabs in this method is relatively large, which reduces the indoor net height, and the connection method is welded on site, so the assembly efficiency is relatively low
