Abstract
A novel prefabricated building connecting joint comprises a prefabricated sandwich superposed wall and a prefabricated superposed top plate, the prefabricated sandwich superposed wall comprises prefabricated layers at the two sides and a sandwich layer in the middle, and the prefabricated superposed top plate comprises a top plate prefabricated layer and a top cast-in-situ layer; a vertical steel bar in the prefabricated layer at one side of the prefabricated sandwich superposed wall stretches out of the bottom end of the prefabricated layer, is bent and turned, and then enters the prefabricated layer at the other side to become a vertical steel bar, or vertical bars in the prefabricated layers at the two sides of the prefabricated sandwich superposed wall stretch out of the bottom ends of the prefabricated layers and are connected to form an overall bent and turned structure, the bent and turned steel bars are anchored in the top plate cast-in-situ layer of the prefabricated superposed top plate, and connection and fixation are achieved through cast-in-situ concrete. The steel bar stress mode in the prefabricated building connecting joint acts as the optimal selection, the strength of the joint is equivalent to that of a cast-in-situ structure, and the prefabricated building connecting joint is high in structural strength and bending resistance.
Description
Technical field
The invention belongs to construction engineering technical field, be specifically related to the connection node of a kind of assembled architecture.
Background technology
In existing assembled architecture, prefabricated sandwich overlapping wall with the connection node of top board is: in the preformed layer of prefabricated sandwich overlapping wall both sides, the vertical reinforcement of stress does not anchor into top board, but insert in top board by setting up two row's vertical reinforcements in prefabricated sandwich overlapping wall sandwich of layers, the bonding strength of node is ensured with this, but these two row's vertical reinforcement spacing set up are narrow, and this most greatly weakens the structural strength that prefabricated sandwich overlapping wall is connected with top board.Structural strength for making both connect is improved, sometimes can only the concrete layer of prefabricated sandwich overlapping wall both sides be made the thinnest, the spacing of two row's vertical reinforcements in sandwich of layers is set up to pull open as far as possible, but this way space fine-adjusting is limited, still can not fundamentally ensure bonding strength and the anti-bending strength of node.
Summary of the invention
The technical problem to be solved is: solve the problem that above-mentioned prior art exists, and provide a kind of novel fabricated building to connect node, making assembled architecture connect node reinforcing steel bar bear mode is optimum selection, node strength equivalent cast-in-place structural, structural strength is high, and anti-bending strength is good.
The technical solution used in the present invention is: novel fabricated building connects node, including prefabricated sandwich overlapping wall and prefabricated overlapping top board, described prefabricated sandwich overlapping wall includes the preformed layer of both sides and middle sandwich in-situ layer, described prefabricated overlapping top board includes top board preformed layer and top board in-situ layer, vertical reinforcement in the preformed layer of prefabricated sandwich overlapping wall side is after bending revolution is stretched out in preformed layer bottom, vertical reinforcement is become in entering back into opposite side preformed layer, or vertical reinforcement connects into Integral bending after preformed layer bottom is stretched out and turns back rotation structure in the preformed layer of prefabricated sandwich overlapping wall both sides, above-mentioned bending revolution Bar Anchorage is in the top board in-situ layer of prefabricated overlapping top board, cast concrete connects fixing.
In technique scheme, it is connected fixing inside described bending revolution reinforcing bar with many horizontal reinforcements.
Prominent substantive distinguishing features and remarkable result:
In existing assembled architecture, prefabricated sandwich overlapping wall inserts in top board by prefabricated sandwich overlapping two vertical reinforcements of in-situ layer within the walls completely with the connection of top board, and this connection node two vertical reinforcement spacing of prior art is little, and anti-bending strength is poor, and structural strength weakens.The present invention revolutionizes the connecting joint structure of this prior art, stretch out reserved from preformed layer bottom for vertical reinforcement in the both sides preformed layer of prefabricated sandwich overlapping wall, two Vertical bar connection stretched out are fixed, integral bending revolving structure, then anchor in the in-situ layer of prefabricated overlapping top board, pour into a mould concrete again and connect fixing, two vertical reinforcement spacing width, anti-bending strength is good, structural strength is high, its vertical reinforcement force way is optimal choice, its node strength is high, its vertical reinforcement force way is the same with tradition cast-in-place structural, its node strength equivalent cast-in-place structural, it it is the most best structural strength.
Accompanying drawing illustrates:
Fig. 1 is the embodiment of the present invention 1 structural representation；
Fig. 2 is the embodiment of the present invention 2 structural representation.
Accompanying drawing marks: 1 prefabricated sandwich overlapping wall, 2 preformed layers, 3 in-situ layers, vertical reinforcement in 4 preformed layers, 5 truss, 6 bending revolution reinforcing bars, 7 horizontal reinforcements, 8 prefabricated overlapping top boards, 9 top board preformed layers, 10 top board in-situ layers, 11 middle wall body.
Detailed description of the invention:
See Fig. 1, Fig. 2, the novel fabricated building of the present invention connects node, including prefabricated sandwich overlapping wall and prefabricated overlapping top board, described prefabricated sandwich overlapping wall includes the preformed layer of both sides and middle sandwich in-situ layer, described prefabricated overlapping top board includes top board preformed layer and top board in-situ layer, vertical reinforcement in the preformed layer of prefabricated sandwich overlapping wall side stretches out from preformed layer bottom in entering opposite side preformed layer after bending revolution becomes vertical reinforcement, or vertical reinforcement connects into Integral bending after preformed layer bottom is stretched out and turns back rotation structure in the preformed layer of prefabricated sandwich overlapping wall both sides, above-mentioned bending revolution Bar Anchorage is in the top board in-situ layer of prefabricated overlapping top board, cast concrete connects fixing, it is connected fixing inside described bending revolution reinforcing bar with many horizontal reinforcements.
Embodiment 2 shown in Fig. 2 is with the difference of the embodiment 1 shown in Fig. 1: in Fig. 2, prefabricated sandwich overlapping wall uses as middle wall body, but its structure and node are identical.
Claims (2)
1. a novel fabricated building connects node, it is characterized in that: include prefabricated sandwich overlapping wall and prefabricated overlapping top board, described prefabricated sandwich overlapping wall includes the preformed layer of both sides and middle sandwich in-situ layer, described prefabricated overlapping top board includes top board preformed layer and top board in-situ layer, vertical reinforcement in the preformed layer of prefabricated sandwich overlapping wall side is after bending revolution is stretched out in preformed layer bottom, vertical reinforcement is become in entering back into opposite side preformed layer, or vertical reinforcement connects into Integral bending after preformed layer bottom is stretched out and turns back rotation structure in the preformed layer of prefabricated sandwich overlapping wall both sides, above-mentioned bending revolution Bar Anchorage is in the top board in-situ layer of prefabricated overlapping top board, cast concrete connects fixing.
Novel fabricated the most according to claim 1 building connects node, it is characterised in that: it is connected fixing inside described bending revolution reinforcing bar with many horizontal reinforcements.
