The cross section of the utility model takes the M shape; the blocking button takes a protruding semi-circular type which leads the upper plane of the lab joint to be a groove type combination, the fitting is close, the flatness is high, the blocking buttons are firm, and the firmness of the main keel is improved; the structure thereof is simple and the disassembly thereof is easy, and the utility model can be used in indoor decorative ceiling of buildings.
Description
Technical field
The utility model belongs to building finishing member field, is specially a kind of draw-in groove type main joist that is used for fixing decoration panel.
Background technology
At present, indoor furred ceiling finishing is main to adopt major and minor keel cross to cooperate, and installs suspension rod additional and fix, and main joist is generally the cell cube of specification, in the construction, each cell cube main joist adopts grab or buckle to be overlapped to form Len req, because the bond end cross section of existing main joist is n type shape, buckle is indent half back taper type, it is bad to exist faying surface applying degree, buckle is not firm, and steadiness is poor, deficiencies such as dismounting effort.
The utility model content
Technical problem to be solved in the utility model is, overcomes the problem that prior art exists, and provides a kind of applying degree good, and buckle is firm, improves the draw-in groove type main joist of steadiness.
In order to address the above problem the technical solution of the utility model is such:
A kind of draw-in groove type main joist for building, comprise the keel body and be arranged on buckle, slotted hole, bayonet socket, hole clipping, lapping, lifting hole(eyelet) on the body, it is characterized in that: described lapping cross section is the M shape, the lapping two sides are provided with the semi-circular buckle to outer lug, and the plane is provided with groove on the body at semi-circular buckle place.
Lapping and body transition knee are provided with fabrication hole.
Beneficial effect, cross section of the present utility model is M type shape, and it is semi-circular that buckle is evagination, and making overlap joint go up the plane is the grooved combination, fit closely, the planeness height, buckle is firm, improves the steadiness of main joist, this, simple in structure, dismounting is easy, can extensively be suitable for building interior decoration ceiling furred ceiling and use.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is the front view of the utility model structural representation;
Fig. 2 is the vertical view of the utility model structural representation:
Fig. 3 is the right view of the utility model structural representation:
Fig. 4 is an A-A sectional view among Fig. 1.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Consult Fig. 1, Fig. 2, shown in Figure 3, a kind of buckle-type grooved main joist, mainly comprise body 01, buckle 02, groove 03, slotted hole 04, bayonet socket 05, hole clipping 06, lapping 07, lifting hole(eyelet) 08, fabrication hole 09, its body 01 is the cell cube of lightweight metal material, cross section is M type shape, body 01 two sides are provided with the slotted hole 04 of ventilative or weight reduction, the plane is provided with lifting hole(eyelet) 08 and fabrication hole 09 on the body 01, lifting hole(eyelet) 08 is used for suspension rod and passes, fabrication hole 09 is as lapping 07 usefulness with body 01 transition position bending: an end of body 01 is lapping 07, lapping 07 two sides are provided with the semi-circular buckle 02 to outer lug, the other end of body 01 is provided with hole clipping 06, during two bodies, 01 overlap joint, the buckle 02 of a body 01 is installed in the hole clipping 06 of another body 01, and the camber bayonet socket 05 that 01 liang of base of body is provided with is used for clamping combination with rider keel.
Please continue shown in Figure 4ly, lapping 07 place's cross section of body 01 is M type shape, and last plane is provided with groove 03, fit closely when making two bodies, 01 overlap joint, the planeness height, the semi-circular buckle 02 of evagination is firm with clamping of square hole clipping 06 in addition, and the stability of main joist is improved.
Because cross section of the present utility model is M type shape, it is semi-circular that buckle is evagination, and making overlap joint go up the plane is the grooved combination, fits closely, the planeness height, buckle is firm, improves the steadiness of main joist, this, simple in structure, dismounting is easy, can extensively be suitable for building interior decoration ceiling furred ceiling and use.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the manual just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
