Abstract

The utility model discloses a multifunctional card-type primary joist, a cross section of which is an open trapezoid (1), a hanger rod hole (2) is arranged on the top and the lower edges at both sides are symmetrically provided with a plurality of clamping position units (3), each of the clamping position unit (3) consists of a clamping position (4) which takes the form of a big anchor and a clamping position (5) which takes the form of a small anchor, the hook end (6) of the clamping position (4) which takes the form of a big anchor warps tilts upwards and is provided with a camber clamping groove (7), the hook end (8) of the clamping position (5) which takes the form of the small anchor is flat and straight in shape and is provided with a straight clamping groove (9). The multifunctional primary joist which adopts the structure can realize various functions can be utilized to hang light steel secondary joist or the aluminum square tube or to hang the aluminum square tube and a V-shaped pinch plate at the same time and the structure is very stable.

Description

Multi-functional cassette main joist

Technical field

The utility model relates to a kind of architectural decoration five metals material, particularly a kind of multi-functional cassette main joist.

Technical background

The cassette main joist that adopts in the existing building decoration construction, though be provided with screens of big anchor shape and the screens of grapnel shape, the design of its big anchor shape screens is not quite reasonable, the screens of grapnel shape only plays decoration function, generally can only hang light steel paired joist, and structure is firm inadequately, and function singleness is demanded urgently improving.

The utility model content

The technical problems to be solved in the utility model provides a kind of multi-functional cassette main joist, can realize multiple function, and structure is firm.

For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of multi-functional cassette main joist, its cross section is that opening is trapezoidal, the top is provided with boom hole, and the both sides lower edge is provided with some groups of card postion units symmetrically, and every group of card postion unit is made up of screens of a big anchor shape and the screens of a grapnel shape, the hook end of big anchor shape screens is upturned, on arc-shaped slot is arranged, the hook end of grapnel shape screens is a flat shape, on straight draw-in groove is arranged.

Adopt the multi-functional cassette main joist of said structure, can realize multiple function, both can be used for hanging light steel paired joist, can be used for hanging the aluminium square tube again, also can be used for hanging simultaneously aluminium square tube and V-arrangement buckle, and structure is very firm.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is the stereogram of described utility model;

Fig. 2 is the front view of described utility model;

Fig. 3 is one of user mode figure of described utility model;

Fig. 4 be described utility model user mode figure two;

Fig. 5 be described utility model user mode figure three.

The specific embodiment

Referring to Fig. 1, Fig. 2, a kind of embodiment of multi-functional cassette main joist is provided, its cross section is that opening is trapezoidal 1, the top is provided with boom hole 2, can connect suspension rod 3, and hangs on the roof by suspension rod 10.Its both sides lower edge is provided with some groups of card postion units 3 symmetrically, every group of card postion unit 3 is made up of big anchor shape screens 4 and grapnel shape screens 5, the hook end 6 of big anchor shape screens 4 is upturned, on arc-shaped slot 7 is arranged, the hook end 8 of grapnel shape screens 5 is a flat shape, on straight draw-in groove 9 is arranged.

The cassette main joist of this structure, can realize multiple function, both can be used for hanging this ceiling material of light steel paired joist, can be used for hanging this material that directly presents decorative effect of aluminium square tube again, also can be used for hanging simultaneously these two kinds of materials that directly present decorative effect of aluminium square tube and V-arrangement buckle.

Referring to Fig. 3, in the construction, when hanging light steel paired joist, the button bit groove 12 of top, light steel paired joist 11 both sides inserts in the arc-shaped slot 7 of big anchor shape screens 4, and the bottom land of button bit groove 12 and hook end 6 tightly offset, and structure is firm.

Referring to Fig. 4, when hanging aluminium square tube 13, the button bit right angle flanging 14 of top, aluminium square tube 13 both sides inserts the straight draw-in groove 9 of grapnel shape screens 5, tightly offsets with hook end 8, and structure is firm, has realized a kind of function that directly presents decorative effect.

Referring to Fig. 5, when hanging aluminium square tube 13 and V-arrangement buckle 15 simultaneously, because after above-mentioned aluminium square tube 13 inserts the straight draw-in groove 9 of grapnel shape screens 5, straight draw-in groove 9 also leaves the slit, again with the both sides button bit flanging 16 of V-arrangement buckle 15, insert respectively in the slit of two position straight draw-in grooves 9 in opposite directions in the two adjacent groups card postion unit, the button bit flanging 16 of V-arrangement buckle 15 is tight against on the button bit right angle of aluminium square tube 13 flanging 14 at this moment, double-dealing person tightly offsets with hook end 8 together, structure is firm, has realized the another kind of function that directly presents decorative effect.

Claims

1. multi-functional cassette main joist, its cross section is opening trapezoidal (1), the top is provided with boom hole (2), the both sides lower edge is provided with some groups of card postion units (3) symmetrically, it is characterized in that: every group of card postion unit (3) is made up of big anchor shape screens (4) and grapnel shape screens (5), and the hook end (6) of big anchor shape screens (4) is upturned, on arc-shaped slot (7) is arranged, the hook end (8) of grapnel shape screens (5) is a flat shape, on straight draw-in groove (9) is arranged.
