Description
Technical field
The utility model relates to a kind of indoor top surface decoration accessory, particularly decorates end face expanded joint structure.
Background technology
House roofings is the quality of the important component part of interior decoration, its decorative effect, directly affects the decorative effect of whole architectural space.House roofings finishing is divided into direct-type and suspension two kinds, wherein, direct-type is for directly to apply ornament materials at soffit, be generally used for the place that cosmetic requirement is not high, suspension has another name called furred ceiling, be form of construction work conventional in current interior decoration engineering, allow indoor have insulation, heat insulation, the effect of insulating against sound.
But, end face is decorated in furred ceiling finishing, along with the environmental change such as temperature, humidity easily produces crack, and As time goes on, crack can be more and more wider, more and more longer, existing solution adopts closed U-shaped structure, the method of sticking with glue is fixed, the defect that this structure exists is: the impact that large-area plaster tablet suspended ceiling is expanded with heat and contract with cold is comparatively large, and traditional closed U-shaped flexible position easily occurs cracking defect, keeps in repair slightly higher; Gluing is installed insecure, more easily cross pollution occurs.
Notification number is that the utility model patent of 203022280U provides a kind of syndeton of decorating end face shrinkage joint, but this structure is comparatively complicated, and cost of manufacture is higher.
Utility model content
In order to overcome the shortcoming of prior art, the utility model provides decoration end face expanded joint structure, by adopting a kind of overlapping shrinkage joint processing scheme, ensureing that decoration completes end face and do not occur cracking phenomena, reducing maintenance rate, save construction cost, durable in use.
Technical solutions of the utility model are as follows:
Decoration end face expanded joint structure, comprise screw mandrel, main joist and rider keel is provided with below described screw mandrel, the below of described rider keel is provided with skin plate, described skin plate is provided with shrinkage joint, and described shrinkage joint place is provided with Z-type connector and L-type connector, and the lap length d of described Z-type connector and L-type connector is at least 10mm, described Z-type connector is all connected with skin plate by self-tapping screw with L-type connector, and described self-tapping screw is also connected with rider keel.
As preferably, described Z-type connector and L-type connector overlap inner corner trim place and leave 3mm gap.
As preferably, described L-type connector and Z-type connector are provided with some punchings, and described punching hole diameter size is 3-6mm, adjacent two punching spacing 8-12mm.
As preferably, described Z-type connector and L-type connector are formed by the thick galvanized sheet iron of 0.45mm.
The utility model beneficial effect is: 1) utilize Z-type connector and L-type connector mutually to overlap dexterously, replace traditional U-shaped structure, and described Z-type connector and L-type connector overlap best results when inner corner trim place leaves 3mm gap, enough strokes are provided for expanding with heat and contract with cold, decrease the phenomenon of end face cracking, extend application life; 2) described Z-type connector is all connected with skin plate by self-tapping screw with L-type connector, be connected firmly, and self-tapping screw is also connected with rider keel, enhances the fastness at whole shrinkage joint; 3) described Z-type connector and the thick galvanized sheet iron of the preferred 0.45mm of L-type connector are formed, sound construction.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Consult Fig. 3 to Fig. 5.
Decoration end face expanded joint structure, comprise screw mandrel 1, main joist 2 and rider keel 8 is provided with below described screw mandrel 1, the below of described rider keel 8 is provided with skin plate 3, described skin plate 3 is provided with shrinkage joint, and described shrinkage joint place is provided with Z-type connector 5 and L-type connector 4, and described Z-type connector 5 is at least 10mm with the lap length d of L-type connector 4, described Z-type connector 5 is all connected with skin plate 3 by self-tapping screw 7 with L-type connector 4, and described self-tapping screw 7 is also connected with rider keel 8.
Described Z-type connector 5 overlaps inner corner trim place with L-type connector 4 and leaves 3mm gap.
Described L-type connector 4 and Z-type connector 5 are provided with some punchings 6, and described punching 6 diameter is 3-6mm, adjacent two punching spacing 8-12mm.
Described Z-type connector 5 and L-type connector 4 are formed by the thick galvanized sheet iron of 0.45mm.
Installation process of the present utility model is:
Outer expansion bolt sleeve pipe is squeezed into the hoisting point position accomplishing fluently eye in advance, and rotated by screw mandrel 1 and be screwed into until tighten in sleeve pipe, require screw mandrel 1 perpendicular to agent structure floor layer perpendicular to furred ceiling surface layer, not run-off the straight is even bending; For convenience of the planeness of adjustment suspended ceiling framework, appropriate to the occasion slightly long about 50 ㎜ of screw mandrel 1 blanking.
Main joist 2 is installed to other one end successively from one end in position according to screw mandrel 1, if there is high-low bay, first installs high across part, and then installs low across part.Meet shrinkage joint main joist 2, rider keel 3 all disconnection process.
Skin plate 3 fixing should surrounding galvanized steel self tapping screw from from the centre of plate to plate directly with rider keel 3, fixing, can not multiple spot operation simultaneously, in order to avoid produce internal stress, lay injustice; In plate, the spacing of self-tapping screw is preferably about 200mm and is not more than 250mm; Head of screw slightly should sink to plate face 0.5 ~ 1 ㎜, and paper must not be made damaged; 5 ~ 8 ㎜ gaps should be stayed between plate and plate; Expansion joint position, staggers about 100mm in the position that the disconnection of skin plate need disconnect with keel.
Shrinkage joint end opening rushes φ 5mm hole punching spacing 10mm, adopts self-tapping screw Z-type connector 5 to be fixed on end face skin plate 3, rear installation L connector; These two parts are taked at overlap joint inner corner trim place to stay seam 3mm process, and Z-type connector lap length d need cover L-type connector 10mm(sees accompanying drawing 5); After the installation of whole shrinkage joint, then carry out postorder covering with paint operation.This structure, can effectively avoid because of impact of expanding with heat and contract with cold, and the end face skin plate problems of crack produced, thus greatly reduce maintenance rate, save construction cost; And install firmly, can not cross pollution be there is.
Above-mentioned drawings and Examples are only for illustration of the utility model, and any art those of ordinary skill to its suitable change done or modification, or is used other flower pattern instead and made this technical change, all should be considered as not departing from the utility model patent category.
