Rigid connection, 8 two sides of tension rib are equipped with grasp, and the side grasp of tension rib 8 is anchored in inwall 6, and 8 other side of tension rib is worn
It crosses polyphenyl plate heat preserving layer 7 and extends to brick wall body 1, the other side grasp of tension rib 8 is anchored in brick wall body 1, tension rib 8
Grasp is L shape or U-shaped etc., and the setting of tension rib 8 can enhance the bonding strength of inwall 6 Yu brick wall body 1, makes the two securely
It is connected as one.
As shown in Figure 1 to Figure 3, it is embedded in the center line of 8 grasp of tension rib in brick wall body 1 and close to inwall 6 one
The distance on 1 surface of side brick wall body is the 1/2~2/3 of 1 thickness of brick wall body, guarantees that the grasp of tension rib 8 being capable of stable anchorage
In in brick wall body 1.
Please continue to refer to Fig. 1 to Fig. 3, it is in matrix that multiple tension ribs 8 are transversely and longitudinal direction is placed equidistant in inwall 6
Shape is distributed in inwall 6, and more preferably, the spacing of two neighboring tension rib 8 is 500mm, so that 6 stress of inwall is more balanced.
Illustrate the flexible connecting method of inwall of the present invention and main structure in conjunction with Fig. 1 to Fig. 6, the specific steps are as follows:
After line setting is qualified, assembling reinforcement and tension rib 8 is set in inwall 6 to be poured, by the perpendicular of inwall 6
It is connected to 4 reinforcing bar of lower layer's floor to reinforcing bar, one end of tension rib 8 is anchored in brick wall body 1, and the other end of tension rib 8 is located at
In inwall 6 to be poured；
At 6 top of inwall to be poured, multiple connectors 10, the pinboard 11 of connector 10 are set along its length
It is fixed in 3 bottom frame of upper layer floor to set a roof beam in place 5 lower flanges, the card slot 12 of connector 10 is embedded in 6 top of inwall；
Formwork after-pouring concrete completes inwall 6 and constructs, and 11 bottom of pinboard is embedded in the notch of card slot 12, and
Styrofoam is set in the gap between inwall 6 and Vierendeel girder 5, structural column 2 and does filleting processing so that inwall 6 with it is upper
Floor plate 3, structure on two sides column 2 are flexibly connected.
The flexible connecting method of inwall of the present invention and main structure, firstly, the assembling reinforcement in inwall 6 to be poured
And tension rib 8 is set, 6 vertical reinforcement of inwall is connect with 4 reinforcing bar of lower layer floor, and the other end of tension rib 8 is embedded in wait pour
The brick wall body 1 in 6 outside of inwall installs multiple connectors 10 along 6 length direction of inwall, and the pinboard 11 of connector 10 is solid
It is connected to 3 bottom frame of upper layer floor to set a roof beam in place 5 lower flanges, the card slot 12 of connector 10 is embedded in 6 top of inwall, 6 coagulation of inwall
After the completion of soil pours, 11 bottom of pinboard is embedded in the notch of card slot 12, meanwhile, inwall 6 and Vierendeel girder 5, structural column 2
Between gap in be arranged and styrofoam and do filleting processing, to realize the flexible connection of inwall 6 Yu main structure；The present invention
Inwall 6 and the flexible connecting method of main structure not only can effectively enhance the globality of building structure, but also not will increase main body
The rigidity of structure, and have in the Aseismic Design of building structure entirety；Moreover, in the construction process, inwall 6 can be used as inside and outside
The interface of decorations construction separates, and indoor and outdoor synchronous construction and is independent of each other, can substantially shorten construction period.
