Abstract
A novel prefabricated building connecting joint comprises a prefabricated sandwich superposed wall and a prefabricated superposed bottom plate, the prefabricated sandwich superposed wall comprises prefabricated layers at the two sides and a sandwich layer in the middle, and the prefabricated superposed bottom plate comprises a bottom plate prefabricated layer and a bottom 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 bottom plate cast-in-situ layer of the prefabricated superposed bottom 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 cast-in-place base plate is: in the preformed layer of prefabricated sandwich overlapping wall both sides, the vertical reinforcement of stress does not anchor into cast-in-place base plate, but insert in cast-in-place base plate 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 Bars In Poured Concrete Slab.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 providing a kind of novel fabricated building to connect node, the reinforcing steel bar bear mode making assembled architecture connect node 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 base plate, described prefabricated sandwich overlapping wall includes the preformed layer of both sides and middle sandwich in-situ layer, described prefabricated overlapping base plate includes base plate preformed layer and base plate 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 base plate in-situ layer of prefabricated overlapping base plate, 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 leans on two vertical reinforcements of prefabricated sandwich overlapping in-situ layer within the walls to insert in cast-in-place base plates with the connection of cast-in-place base plate completely, 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, being stretched out from preformed layer bottom by vertical reinforcement in the both sides preformed layer of prefabricated sandwich overlapping wall, the two vertical reinforcement bending revolutions stretched out connect fixing, then anchor in cast-in-place base plate, pour into a mould concrete again and connect fixing, two vertical reinforcement spacing width, anti-bending strength is good, and structural strength is high, its vertical reinforcement force way is the same with tradition cast-in-place structural, its node strength is high, is equal to cast-in-place structural, 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；
Fig. 3 is the embodiment of the present invention 3 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 base plates, 9 base plate preformed layers, 10 base plate in-situ layers, 11 middle wall body, 12 steel plate for sealing water, 13 embedded bars, 14 stirrups, 15 rainwater box culverts.
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 base plate, described prefabricated sandwich overlapping wall includes the preformed layer of both sides and middle sandwich in-situ layer, described prefabricated overlapping base plate includes base plate preformed layer and base plate in-situ layer, vertical reinforcement in the preformed layer of prefabricated sandwich overlapping wall side stretches out the vertical reinforcement that becomes entering in opposite side preformed layer after bending revolution and connects into Integral bending after preformed layer bottom is stretched out and turn back rotation structure from preformed layer bottom, in above-mentioned preformed layer the bottom of vertical reinforcement stretch out reserved steel bar bending revolving structure be anchored in the base plate in-situ layer of prefabricated overlapping base plate, cast-in-place concrete connects fixing, it is connected fixing inside the reinforcing bar of described general frame structure with many horizontal reinforcements.
The difference of Example 1 and Example 2 of the present invention is: the prefabricated sandwich overlapping wall of embodiment 1 is as side wall, and the prefabricated sandwich overlapping wall of embodiment 2 is as middle wall body；Embodiment 3 shown in Fig. 3 is with the difference of the embodiment 2 shown in Fig. 2: embodiment illustrated in fig. 33 is with rainwater box culvert.
