Technical field
What the present invention relates to is a kind of method and device of construction engineering technical field, and specifically a kind of catamaran type metal ceiling for indoor assists keel and technique optimization method thereof.
Background technology
Along with developing rapidly of modern architecture industry and new and high technology, modern sense strong, the Architectural Equipment of tall and big magnificence, as: high star hotel, fair, airport, harbour, conference centre, theater etc. are to interior decoration, especially to metal ceiling and decorative ceiling board not only magnificence attractive in appearance but also durable requirement, in the technical field being applied in whole building and decoration and industry.Existing indoor suspended ceiling generally adopts the keel of the c character form structure in Fig. 1 shown in a-d, T-shaped structure, n character form structure, or directly hangs panel, and these structures respectively have its shortcoming and defect.
The keel rheobase of n character form structure originally can meet the weight requirements of medium-and-large-sized aluminium alloy panel, but this structure preparation process operation is comparatively complicated, especially in the end keel formative stage needs that wider keel panel is folded to n character form structure gradually from plane needs to expend larger man-hour, and has higher requirements to the length of machining tool and power output.The keel preparation section of C character form structure is comparatively simple, but makes due to its unsymmetric structure the construction demand being difficult to meet large aluminum alloy panel, and long-time use after in order to cause material deformation; As by selecting hardness higher material or reinforcement material thickness then will directly to improve the requirement of manufacturing process and lathe.Although the keel of T-shaped structure are symmetrical structure, and intensity meets the demands substantially, its manufacturing process is then the most complicated in all keel and man-hour is longer, should not deposit in a large number more greatly once take up an area volume after preparing finished product.
Find by prior art documents, Chinese patent literature CN201265204, publication date 2009-07-01, disclose a kind of keel for furred ceiling, this technology is provided with the groove that runs through skeleton body between flank and flank, and flank is at least provided with one with groove vertical and through groove, groove is arranged on lower floor's steel plate, the two ends of skeleton body are respectively provided with a connection fastener, are provided with the mesopore corresponding with groove location in the middle part of skeleton body.
Chinese patent literature CN2903219 publication date 2007-05-23; disclose a kind of main joist with stereo groove; this technology comprises the top muscle connected successively; web and wing plate; web two ends are provided with and two tenons that joint face contrary symmetrical along web length direction center line, and tenon comprises and is arranged on tongue on web and plug, and tongue is waveform dual slope structure; openend updip, is arranged on inside plug; Plug is concave configuration, is arranged on web one end, and main body is list structure, and its external part outermost part tilts to the concave direction away from plug, and with plug body angulation, plug external part front end is provided with the grab higher than subject plane; Plug inner side edge inwardly has window to web corresponding to the inside first break position of tongue free end; Plug ragged edge is followed to nearest web back gauge equal to the distance on nearest web limit with tongue tongue, equal to the nearest back gauge of web with plug inner side edge to the nearest back gauge of web inside grab.But above-mentioned technical disadvantages is only the first between keel with keel being connected, and the structure of monolithic keel still belongs to T-shaped structure, and manufacture craft is comparatively complicated.
Summary of the invention
The present invention is directed to prior art above shortcomings, propose a kind of catamaran type metal ceiling and assist keel and technique optimization method thereof, while minimum change is carried out to existing lathe, the ceiling joist that quick volume production structural strength meets industrial requirement can be reached, be applicable to medium-and-large-sized aluminium alloy indoor suspended ceiling panel.
The present invention is achieved by the following technical solutions

The present invention relates to the catamaran type metal ceiling that said method prepares and assist keel, comprising: some mutually isostructural auxiliary keel, each auxiliary keel are provided with successively some to fixed mechanism.
Described auxiliary keel are vertically provided with some to the holddown groove for connecting main joist.
Described fixed mechanism comprises: positioning tooth and hole clipping, and wherein: positioning tooth and hole clipping are positioned at same level, preferably positioning tooth and hole clipping are positioned on the symmetry axis of auxiliary keel.
Described positioning tooth is the tab structures that one end is connected with auxiliary keel, and is provided with the salient point relative with protrusion direction in the middle part of the main body of positioning tooth.
The width of described hole clipping and the width of positioning tooth match, and described auxiliary keel are provided with the anchor point of corresponding salient point, and this anchor point is between hole clipping and positioning tooth.
Described salient point and the shape of anchor point match each other, and are preferably triangle.
The beeline of described anchor point distance hole clipping is less than the air line distance of described salient point to positioning tooth edge.
Technique effect
Compared with prior art, the present invention, by adjusting by a small margin existing technique, obtains the double-layer keel that intensity can meet completely existing medium-and-large-sized hang ceiling panel demand while can either keeping high speed output.And the symmetrical keel of two panels increase frictional force with the face way of contact, are aided with symmetrical multi-layer hole clipping structure and fix, be connected firmly and can stand load-bearing that is long-time, high strength.
