The profile structure of building curtain wall
Technical field
The utility model is the profile structure about a kind of building curtain wall, particularly a kind ofly can process in advance, reaches quality requirement easily, satisfies the different demands of architectural decoration and can reduce the profile structure of the building curtain wall of curtain wall manufacturing cost.
Background technology
Along with the develop rapidly of building trade, the architectural design of various moulding excellences such as large space, large span, facade are penetrating emerges in an endless stream, and makes curtain wall utilization under construction more and more widely.The support frame of building curtain wall can be made of aluminium and steel.Make framework with aluminium, though in light weight, handling ease is convenient, appearance looks elegant, and for the building structure of large space, large span, the rigidity of the support frame that aluminium is made can not meet the demands, makes framework so develop into steel.Support frame with steel are made is divided into rod-pulling type, drag-line and three kinds of forms of truss-like at present again.Adopt rod-pulling type and drag-line structure to belong to flexible support structure, in the installation process, all must apply prestressing force, and prestressed calculating more complicated needs the professional and technical personnel to finish, and need special erection equipment, also specific (special) requirements need be arranged to the main building structure simultaneously, use truss structure, be generally the welded construction of shaped steel, and welding easily produces internal stress and distortion, is difficult for guaranteeing the design and installation requirement of curtain wall; And the lead frame efficiency of construction is low at the construction field (site), and is difficult for ensuring the quality of products.
Summary of the invention
In order to overcome the deficiency of braced structures in the above-mentioned prior art, the purpose of this utility model promptly is to provide a kind of can process in advance, reach quality requirement easily, satisfy the different demands of architectural decoration and can reduce the profile structure of the building curtain wall of curtain wall manufacturing cost.
The purpose of this utility model is achieved through the following technical solutions:
The profile structure of the utility model building curtain wall is provided with two blocks of column Ji plates and is connected at least one block of column web between these two blocks of column Ji plates, is to fixedly connected between this column Ji plate and this column web wherein.
In the profile structure of above-mentioned building curtain wall:
Be to be fixed together between this column Ji plate and this column web wherein by being spirally connected of securing member.
Be to be fixed together between this column Ji plate and this column web wherein by spot welding.
Be on the plate face of this column Ji plate, to be provided with through hole between this column Ji plate and this column web wherein, be fixed together by being spirally connected of securing member again.
Be on the plate face of this column Ji plate, to be provided with through hole between this column Ji plate and this column web wherein, be fixed together by spot welding again.
Wherein be provided with through hole on the plate face of Ji plate, thirty years of age column web corresponding section is provided with the counterbore of appropriate depth, is fixed together by spot welding again.
Because the profile structure of above-mentioned building curtain wall has adopted said structure, makes section bar to shape in advance in factory, only connect assembling at the construction field (site), or impose a small amount of welding, therefore saved the engineering time greatly; In addition, owing to only adopted a small amount of welding, thus internal stress is little, and welding deformation is little, reaches the requirement of designing quality easily; Simultaneously, adopt the profile structure of profile structure of this building curtain wall simple, material usage is few, and support strength is big, thereby has reduced the manufacturing cost of curtain wall.

The specific embodiment
Please together with reference to figure 1, the profile structure of the utility model building curtain wall roughly is " H " shape, be provided with two blocks of column Ji plates 1 and be connected column web 2 between these two blocks of column Ji plates 1, wherein the plate face central axis of this column Ji plate 1 is provided with countersunk head through hole 12, and the corresponding section is provided with screw 22 on the central axis of the two sides of this column web 2, so can be connected and fixed by sunk screw 3 (perhaps adopting securing members such as double-screw bolt, screw) between this column Ji plate 1 and this column web 2.
Certainly, also can adopt spot welding to connect (as Fig. 2) being connected between above-mentioned column Ji plate 1 and the column web 2, promptly only on the vertical perpendicular bisector of plate face of this column Ji plate 1, through hole 14 is set, in this through hole 14, form solder joint 16 by plug welding then, thereby column Ji plate 1 and column web 2 are welded together (please refer to Fig. 2).
In addition, spot welding connected mode between above-mentioned column Ji plate 1 and the column web 2, can also adopt on the vertical perpendicular bisector of plate face of column Ji plate 1 through hole 14 is set, thirty years of age column web 2 corresponding section also is provided with the counterbore 24 (please refer to Fig. 3) of appropriate depth, forms solder joint 16 by plug welding in this through hole 14 and counterbore 24 then.
Please refer to Fig. 4, the section bar of profile structure that is to use the utility model building curtain wall and is used for fixing the user mode figure of cladding glass 4 after constituting framework.
