Problems solved by technology

[0003] For prefabricated concrete structures, the connection mode of nodes is the core issue of the entire structure, and it is also the weakest link. It has high requirements for the reserved positions of holes and construction methods, which is the basis and focus of the overall seismic research of the structure. However, the current In the construction of prefabricated buildings, there are problems such as difficult assembly construction, poor node connectivity, and poor shear resistance.

Embodiment

[0026] Such as Figure 1-7 As shown, a new type of precast concrete beam-column joint, the beam-column joint needs to prepare precast beam 1, precast column 2, angle steel 3, connecting bolt 5 and connecting box bolt 10.

[0027] Such as figure 2 As shown, for the production of prefabricated beam 1, it is necessary to select and arrange the positions of pre-embedded through holes 6 and reserved grouting holes 7 at the beam end, and pre-embed the connection box 9 on the left according to the arrangement of longitudinal ribs 8 , to ensure that the longitudinal reinforcement 8 extends to the end of the beam, and a row of holes for passing through the bolts 10 of the connection box shall be reserved on the prefabricated beam 1 .

[0028] Such as image 3 and Figure 4 As shown, for the manufacture of the prefabricated column 2, the most important thing is to pre-embed the angle steel bolt 4 and the T-shaped steel 13. Embedding is an important step to ensure its shear resistan...

Abstract

The invention discloses a novel prefabricated concrete beam column joint, and belongs to the technical field of building. The novel prefabricated concrete beam column joint comprises a precast beam, aprecast column, angle iron, an angle iron bolt, a connecting bolt, and a connecting box bolt. The precast beam also comprises a beam-end reserved hole, a reserved drilled grout hole, and a connectingbox except a beam body. The precast column also comprises a plurality of pre-embedded T-shaped steel, pre-embedded bolts, and a reserved drilled grout hole. An upper beam end of the precast beam is provided with an L-shaped gap. The upper end of a joint of the precast column is provided with a U-shaped gap. Earlier stage connection of the novel prefabricated concrete beam column joint is all boltconnection. The joint is reliable in connection and reasonable in load carrying, and does not need weld on site, and construction speed is relatively fast. After construction ends, construction traces are not reserved on the external part, and the joint is tidy and beautiful.

Description

technical field [0001] The invention relates to the field of construction, in particular to a novel prefabricated concrete beam-column joint and a construction method thereof. Background technique [0002] Prefabricated buildings refer to factory prefabricated concrete structural components, which are hoisted and assembled on site to form the overall structural style of the house. It is also an important part of the modernization of the construction industry. The assembly methods of components generally include on-site post-cast laminated concrete, steel bar anchored post-cast concrete connection, etc. The steel bar connection can be connected by sleeve grouting connection, welding, mechanical connection and lap joint connection with reserved holes. Prefabricated concrete components have many advantages such as environmental protection, saving formwork, convenient installation, and shortening the construction period. According to data, when the prefabrication rate of the hou...
