Background
The prefabricated concrete structure is widely applied at home and abroad due to the advantages of high production efficiency, convenient assembly, environmental protection, energy conservation and the like. The low-multilayer fully-assembled bolt connection wallboard type reinforced concrete structure has better technical and economic advantages. The modular unitized wallboard integrating the vertical bearing member and the space division function is connected with each other by horizontal bolts in the horizontal direction, and the wallboard type assembly structure connected with the beam (or the foundation beam) improving the structural integrity in the vertical direction has the best construction efficiency and the structural integrity advantage and can resist larger earthquake action. This form of construction is being used in a wide variety of applications. The node of the beam has enough strength, rigidity and bearing capacity, which is one of the key technologies for realizing large span and complex structural form of the structure; meanwhile, the node completely realizes on-site concrete-free wet operation and can disassemble and reassemble the structure at any time, so that the railway room and the military room are solved, and particularly, the core which has short construction time, good durability after long-time use and can be disassembled and assembled for multiple times is positioned. In the prior art, there are major disadvantages as follows:
(1) the connecting nodes of the beams need to be additionally provided with templates for wet joint pouring concrete connection, so that the beams cannot be repeatedly used;
(2) the vertical flat plate (steel plate) bolt connection node of the beam only has vertical rigidity and bearing capacity, has smaller load bearing capacity, and is only suitable for the condition that a wallboard exists under the beam;
(3) when no wallboard is arranged under the beam or no floor slab is connected with the beam, the safety of a large-span structure and a complex structure cannot be ensured;
(4) in a narrow space with the length of only 300mm, the minimum width of the upper section of 120mm and the minimum width of the lower section of 220mm, due to the existence of construction errors, the construction precision of node connection is difficult to ensure, and the structural safety is reduced;
(5) in the prior art, the beam node form capable of being repeatedly disassembled and assembled for use is very rare.
Aiming at the problems in the prior art, a novel beam node structure for connecting the fully-assembled reinforced concrete wallboard with the bolts and resisting the vertical bending is researched and designed, so that the problem in the prior art is very necessary to be overcome.

The anchoring scheme has the technical advantages that a complex technical process is realized on a narrow beam section by a simple method, and the anchoring requirements of the structural beam in different bearing capacity ranges can be completely met.
The outer side of the beam-end steel plate anchor is the connecting part of the beam end and the beam end. The vertical steel plate and the beam end steel plate are welded to serve as the base plate, so that the vertical bending resistance of the node (the node mainly bears vertical bending moment and shearing force) is provided, and the base plate is also welded with the steel plate for horizontal connection. The horizontal connection steel plates are divided into upper and lower sides (upper horizontal connection steel plates and lower horizontal connection steel plates) and a middle horizontal connection steel plate.
