Abstract

The utility model disclose a supporting frame, in particular to a supporting frame for building curtain wall, aiming to overcome the problem that the truss type supporting frame which is made by welding in the prior art is of large internal stress, easy disfiguration and time consuming for processing and installing on site. The technical proposal of the utility model is that: the shaped steel of the supporting frame comprises two steel plates which are orthogonal, which are wing plate and web plate, and a ''T'' shaped steel which consists of at least two screws and binds two steel plates tightly. One kind of the ''T'' shaped steel is called column stand, the other kind is called beam. The component position relation of the column stand and the beam is that: the web plate of the column stand is intersected with the web plate of the beam; one long side of the top surface of the wing plate of the column stand is coincident with the short side of the top surface of the beam. Besides, two fixing pin axles and at least a screw are arranged between the column stand and the beam, wherein the fixing pin axles are parallel arranged on two sides of the combining line or the combining surface which is between the wing plate of the column stand and the wing plate of the beam, the screw is used to fix the wing plate of the column stand and the web plate of the beam.

Description

The support frame of building curtain wall

Technical field

The utility model relates to a kind of support frame, especially a kind of support frame of building curtain wall.

Background technology

Along with the develop rapidly of building trade, large space, large span, facade is penetrating, and the various architectural designs of moulding excellence emerge in an endless stream, and make 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, good looking appearance, 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, need the professional and technical personnel to finish, and need special erection equipment, specific (special) requirements need be arranged the main building structure.Use truss structure, be generally the welded construction of shaped steel, and welding easily produces internal pressure and distortion, be 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.In addition, this kind structure can increase curtain wall and take up space, and reduces the building usable floor area.

Summary of the invention

In order to overcome the deficiency of truss-like support frame in the above-mentioned prior art, the purpose of this utility model provides a kind of can processing in advance in factory, only connects assembling at the construction field (site), and the building curtain wall support frame that need not weld.

The utility model solves the problems of the technologies described above the technical scheme that is adopted:

Support frame is made up of shaped steel.The shaped steel that the utility model adopted is by two blocks of mutually perpendicular steel plates, i.e. Ji plate and web, and the T-steel that at least two screws that the two tightens together are formed.T-steel one class of being formed is called column, the another kind of crossbeam that is called.Column and crossbeam combined location relation are: the web of column and the web of crossbeam intersect, and a long limit of column Ji plate top surface overlaps with a minor face of crossbeam end face.And, also comprise the fixed pin shaft of both sides of two bonding surfaces that are positioned at column Ji plate and crossbeam Ji plate abreast or joint line and the screw of at least one vertical columns Ji plate and cantilever diaphragm between column and crossbeam.Above-mentioned column and crossbeam can form support frame in two-dimensional plane or three dimensions.The shape of framework and size are formed the number of the column of framework and crossbeam number and spacing and are determined according to the load that facade designing requirement and curtain wall bear.

Adopt the building curtain wall support frame of above technical scheme, have following beneficial effect:

1. because support frame can be processed in advance in factory, only carry out the assembling of bearing pin and screw attachment at the construction field (site), therefore saved the engineering time greatly;

2. avoided welded construction, thereby internal stress is little, does not have the welding distortion, reach the requirement of designing quality easily;

3. can constitute the framework of various complicated shapes such as plane, curved surface, satisfy the different demands of architectural decoration.

4. simple in structure, material usage is few, and support strength is big, reduces the manufacturing cost of curtain wall wall.And reduced the shared space of curtain wall.

5. not only can be used for building curtain wall, also can be applicable to the place that other needs support frame.

The specific embodiment

The utility model will be further described below in conjunction with accompanying drawing.

Referring to Fig. 1-Fig. 3.Column 1 is made of column Ji plate 1.2 and column web 1.1, and is tightened together by at least two sunk screws 6, and its central post web 1.1 is arranged in the vertically vertical bisector plane of column Ji plate 1.2; Crossbeam 2 is made of cantilever diaphragm 2.1 and crossbeam Ji plate 2.2, and is tightened together by at least two sunk screws 3, and wherein cantilever diaphragm 2.1 is arranged in the vertically vertical bisector plane of crossbeam Ji plate 2.2; Fastening between column 1 and the crossbeam 2 is to realize by two fixed pin shafts 5 and at least one sunk screw 4.Two fixed pin shafts 5 are parallel to each other and be positioned at the both sides of Ji plate 2.2 bonding surfaces of the Ji plate 1.2 of column and crossbeam 2; Sunk screw 4 is fixed together column Ji plate 1.2 and cantilever diaphragm 2.1.The position of column 1 and crossbeam 2 relation is: the web 1.1 of column 1 is mutual vertical with the web of crossbeam 2 2.1, and a minor face of Ji plate 2.2 end faces of long limit of Ji plate 1.2 end faces of column 1 and crossbeam 2 coincides.Corresponding with each sunk screw 3,6,4, the end face C of crossbeam, the screw hole on the end face D of column includes counter sink, to guarantee not give prominence to end face after sunk screw is packed into.Adopt Ji plate and web, the Ji plate of crossbeam and the advantage of web and column and crossbeam of sunk screw vertical columns to be, column end face, crossbeam end face, and unpolarized head of screw on the plane of the support frame formed of column and crossbeam or the broken line plane, be convenient to plate faces such as glass, stone material fixing of curtain wall.The fixing sunk screw number of Ji plate and web on column and the crossbeam is determined according to the bearing load of column or crossbeam.

Referring to Fig. 4.Column 1 and crossbeam 2 have constituted a curtain wall support frame.The curtain wall plane materiel can be glass, stone material, metal sheet or other material shown in number in the figure 7 among the figure, and the plane materiel structure that forms a whole separately in addition is fixed on the support frame with pressing plate and screw, breaks fluid sealant around the plate.
