Description
Technical field
The present invention relates to a kind of job practices of deformation joint, particularly relate to a kind of implicit expression processing method and steel deck-plate of deformation joint between wall surfaces.
Background technology
May cause sensitive part or other necessary position of the distortion of structural deterioration because of day and night temperature, differential settlement and earthquake at building, establishing in advance seam disconnects whole building along overall height, the each several part of building became independently unit after order disconnected, or be divided into the section of simple, rule, homogeneous, and make the seam between each section reach certain width, with needs that can adaptive deformation.
Present stage, China there is no the deformation joint national standard, and in engineering construction, often running into a large amount of deformation joint between wall surfaces needs to process.In traditional deformation joint construction, be generally fitted outside cover plate class, its decorative effect can affect the unity of facade effect, and usually can produce come off, the phenomenon such as seepage.
Summary of the invention
Technical problem to be solved by this invention is to overcome existing deformation joint to affect the wall decoration effect, and can occur coming off, the phenomenon such as seepage, a kind of implicit expression processing method and steel deck-plate of deformation joint between wall surfaces are provided, steel deck-plate is fixed in basic unit, can be thereon by the unified requirement construction surface layer of finish material, do not affect decorative effect, the weather-proof silica gel sealing of 20-30mm seam of reservation solves the problem that deformation joint seepage comes off.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
The implicit expression processing method of deformation joint between wall surfaces of the present invention comprises the steps:
(1) steel deck-plate is made: get two block plates, will be wherein one make three folded structures, become 90～95 ° of angles, 5 one-tenth 30～40 ° of angles of swash plate 3 and swash plate between straight plate 1 and the swash plate 3; Get an other block plate, make two folded structures, become 95 °～100 ° angles between straight plate 2 and the swash plate 4; Then two block plates are overlapped, straight plate 1 and straight plate 2 are positioned at same plane;
(2) deformation joint is processed: the deformation joint notch is carried out preliminary treatment, waterstop is layered on deformation joint, spread steel deck-plate and be fixed on the metope structure with expansion bolt, the installation gauze wire cloth is fixed and is welded on the steel deck-plate, then is closed flat the brush waterproof agent with cement mortar, bonding face brick or coating surface layer, deformation joint is cleaned out, set weather proofing sealant after inlaying the PE rod, get final product.
Further, step (2) described in the implicit expression processing method of above-mentioned deformation joint between wall surfaces is: the deformation joint notch is carried out preliminary treatment, take distortion sealing center as the cardinal point determination installation site, first waterstop is layered on deformation joint, then spread steel deck-plate and be fixed on the metope structure with expansion bolt, then gauze wire cloth is fixedly welded on the steel deck-plate, select 1:2.5 to whitewash with cement mortar and be closed flat, brush waterproof agent twice, bonding face brick or coating surface layer, the cleaning deformation joint, inlay the PE rod, latasuture is pasted the U.S. line paper of adhesive sticker, sets the silicone weather resistant fluid sealant, treating that the glue face solidifies removes U.S. line paper when tack-free, gets final product.
Further, in aforesaid processing method, the unified processing of gauze wire cloth and steel deck-plate can be in the same place, integral installation, integral installation is faster like this.When being installed, waterstop between framework, waterstop and concrete, distinguishes painting water-proof adhesive, to increase waterproof effect.
