Description
Technical field
The present invention relates to construction engineering technical field, particularly to a kind of double-layer curtain wall.
Background technology
Double-layer curtain wall has inside and outside two-layer facade, separated by a distance to form an insulating layer between facade, it is possible to play the effect of green energy conservation.The structure of existing double-layer curtain wall is divided into: internal layer curtain wall is fixed on building body, and the bar of encorbelmenting that outer layer curtain wall is stretched out by building keel is fixed.Owing to bar of encorbelmenting needs to undertake gravity and the wind load of outer layer curtain wall, gravitational load is delivered to building body, and encorbelmenting, bar afterbody produces the biggest moment of flexure, and this proposes very high request to the connection reliability of this position connector.
Summary of the invention
The technical problem to be solved in the present invention is: the gravity of existing double-layer curtain wall outer layer curtain wall is excessive to bar afterbody moment of flexure of encorbelmenting, the problem affecting connector reliability.
For solving above-mentioned technical problem, the invention provides a kind of double-layer curtain wall, including: outer layer curtain wall, internal layer curtain wall, building body, encorbelment bar and drag-line；Described internal layer curtain wall is fixed on described building body, and described outer layer curtain wall is positioned at the outside of described internal layer curtain wall；
Described drag-line is between described internal layer curtain wall and described outer layer curtain wall, and vertical direction is arranged, and its two ends are fixed with described building body respectively；
Described bar of encorbelmenting includes that front bar and rear bar, described front bar and rear bar are fixed by end, and its junction is provided with the through hole passed for described drag-line, and described drag-line keeps tensioned state；
The other end of described rear bar is fixed with described building body, and the other end of described front bar is fixed with described outer layer curtain wall.
Preferably, described drag-line is cable wire.
Preferably, the end of described front bar and rear bar is threaded connection fixing.
This double-layer curtain wall wears drag-line in the middle part of bar of encorbelmenting, for sharing the moment of flexure that outer layer curtain wall gravity produces, the shearing force suffered by bar afterbody of encorbelmenting can be converted into tensile force, and this improves the reliability of bar afterbody fastening of encorbelmenting, it is to avoid long-time use rear overhang rod flexural deformation.
Accompanying drawing explanation
Fig. 1 is the top view of the double-layer curtain wall of the present invention.
Fig. 2 is the side view of the double-layer curtain wall in Fig. 1.
Fig. 3 is the structural representation of the bar of encorbelmenting of the double-layer curtain wall in Fig. 1.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, the detailed description of the invention of the present invention is described in further detail.Following example are used for illustrating the present invention, but are not limited to the scope of the present invention.
Double-layer curtain wall as shown in Figure 1 to Figure 3, including: outer layer curtain wall 1, internal layer curtain wall 2, building body 3, encorbelment bar 4 and drag-line 5.Internal layer curtain wall 2 is fixed on building body 3, and outer layer curtain wall 1 is positioned at the outside of internal layer curtain wall 2.
Drag-line 4 is the steel rope of diameter 30 ~ 50mm, and it is between internal layer curtain wall 2 and outer layer curtain wall 1, and vertical direction is arranged, and its two ends are fixed with building body respectively.
Bar 4 of encorbelmenting includes that front bar 401 and rear bar 402, front bar 401 and rear bar 402 are interfixed by the screw thread of end, and its junction is provided with the through hole 403 passed for drag-line 5, and drag-line 5 keeps tensioned state.
The other end of rear bar 402 is fixed with building body 3, and the other end of front bar 401 is fixed with outer layer curtain wall 1.
This double-layer curtain wall wears drag-line in the middle part of bar of encorbelmenting, for sharing the moment of flexure that outer layer curtain wall gravity produces, the shearing force suffered by bar afterbody of encorbelmenting can be converted into tensile force, and this improves the reliability of bar afterbody fastening of encorbelmenting, it is to avoid long-time use rear overhang rod flexural deformation.
Embodiment of above is merely to illustrate the present invention; and not limitation of the present invention; those of ordinary skill about technical field; without departing from the spirit and scope of the present invention; can also make a variety of changes and modification; the technical scheme of the most all equivalents falls within scope of the invention, and the scope of patent protection of the present invention should be defined by the claims.
