Description
The facing that the present invention relates to interior wall is handled.In particular, the present invention relates to edge to the cross part that is positioned at two body of wall intersections carries out facing and handles.
Extensively adopt drywall board so that form the ceiling and the interior wall in room in builing industry.Drywall board is coated with plaster sandwich layer paper, through strengthening by plaster or appearance and constitutes.Drywall board has and is easy to cut into required size, and is easy to the advantage with various frame fixation.But, be difficult to like this drywall board to be cut, straight and level and smooth thereby its edge keeps, and can form straight bight, and above-mentioned situation is seen from angle attractive in appearance and is needed.In addition, when drywall board was cut into required size, the edge of this plate just exposed.The plaster sandwich layer that this exposes is softer, if the edge that is cut is not carried out to a certain degree protection, then it is broken easily.Locate above-mentioned situation particular importance at the external wall angle.
When wall and ceiling by frame parts, when constituting such as timber, it is straight that formed inboard bight and bight, the outside seldom can keep.The less scale error of wooden frame parts, timber generation warpage, and the inharmonious meeting of construction operation is in the intersection of body of wall and ceiling, and locate to cause not really straight bight in the wall end that is positioned at gateway inlet and passage.When after with drywall board with produce crooked frame parts fixedly the time, the cross part between them also can produce bending.
People have adopted various devices so that to being positioned at two mortarless wall parts press mutually provides level and smooth and durability with the cross part that forms inboard or bight, outside place finish coat at present.In the above-mentioned common unit that adopts, include mortarless wall adhesive tape (tape) and metal bead.Common mortarless wall adhesive tape (tape) is to provide with narrower, the porous paper tape of long strip type that is rolled into volume or the mode of bar.Sometimes this paper is punched so that moisturize permeability, and prevent at above-mentioned adhesive tape back generation bubble.The edge of the drywall board that at first above-mentioned mortarless wall adhesive tape is laid in joint and presses mutually covers it by plaster afterwards, and this plaster is sometimes referred to as " mud ".Form the inclination featheredge of plaster along the edge of above-mentioned adhesive tape, and it is floating so that will be laid with the tape edge of above-mentioned adhesive tape and the border between the drywall board covers.When above-mentioned mud is dry, can lays coating to above-mentioned adhesive tape and mortarless wall, or otherwise they be covered by the wall covering that is fit to.
Plaster is smeared in many technical ability of the both sides in inboard bight needs, so that obtain straight cross part.In addition,, often must smear multilayer plaster, and be a whole day the required drying time between every layer of plaster for the bending that the frame parts that compensates above-mentioned generation warpage and inharmonic construction operation cause.Even like this, still seldom obtain straight bight.Equally, if do not use the very skilled personnel of operative skill, the trowel of plastering when smearing the 2nd side can damage the 1st side of plaster.In case above-mentioned plaster is smeared, and dry, then must carry out polishing to it, until forming the facing degree that is fit to, so that the surface that is suitable for laying coating or wallpaper is provided by sand paper.
In housing construction contractor and buyer, very generally adopt grid and vaulted type (vaulted) ceiling recently.Acute angle is often formed on the top of above-mentioned ceiling.Be difficult to the common trowel of plastering is embedded in the above-mentioned angle.
Because above-mentioned mortarless wall adhesive tape forms by paper, its flexibility is bigger like this, and can match with the various surface configurations at the edge of the drywall board that intersects.When common mortarless wall adhesive tape was used for the bight, the outside of body of wall, because the non-straight shape at the edge that expose, that cut off in adhesive tape and the drywall board matches, the flexibility of above-mentioned like this adhesive tape can cause the border, bight of non-regular shape.Above-mentioned adhesive tape also damages easily, and can not be kept upright, thereby makes bight, the outside suffer the damage of nonvolatil reality.Consequently, the common mortarless wall adhesive tape bight, the outside that can not be used to expose.
Therefore, carry out facing for external side corner sections in building operations and handle, people often adopt the metal bead.L-shaped or the angle steel shape of the cross section of common metal bead, it generally by the rectangular metal that has the hole, is made such as the galvanized steel lath, and this lath produces permanent deformation by 90 ° of bendings so that form the angle steel of long strip type.Above-mentioned metal bead generally be positioned at into square crossing so that at the cross part of the adjacent drywall board in bight, the indoor formation outside.By nail is passed drywall board to impact mode, this metal bead part is fixed with the wooden supporting structure part that is positioned at the drywall board back.
Afterwards thereon plastering so that the metal edge of a wing in the metal bead or leg branching part are covered, the edge of floating plaster, thus and form the inclination featheredge metal edge covered.
When the rigidity of metal bead can make the bight, the outside of inner wall of building have the flattened edge of point, above-mentioned here decoration can be satisfactory from angle attractive in appearance, then adopts the metal bead can produce some serious problems.Through after a while, the metal bead can get rusty, thereby produces rust staining, can know on the surface of wall at place, bight and see above-mentioned rust staining.Generally the edge of the metal edge of a wing or the head of a nail all can not be covered, can influence the required smooth exterior of body of wall like this, the above-mentioned metal edge of a wing or the head of a nail are used for metal bead and drywall board are fixed.Produce the crack through regular meeting in the plaster of on the outer ledge on the edge of a wing is in, smearing.Take place for fear of above-mentioned situation, often smear 2 or 3 layers of plaster, and before one deck, make the dry and sclerosis of existing layer under smearing, this need spend and reach 24 hours time.When since below the problem of framework, when above-mentioned bight produced bending or indentation, the metal bead can not cover enough big surface area, or did not have enough flexibilities so that compensate produced not concordant.Another problem is: the ductile metal that constitutes the metal bead has very poor memory, and it can produce indenture or produce fold, then is difficult to afterwards its alignment is formed level and smooth finish coat.Because the coarse operation that most material stood at the construction field (site), above-mentioned lath can often produce fold, indenture, or be distorted, thereby they can not be used, or only be used to produce relatively poor final result.In addition, when construction, can adopt above-mentioned laths of metal in a large number, can cause cost higher like this.
In order to solve the above problems, people have developed multiple drywall corner finishing device.In these devices, comprise following form:
