Description
Technical field
The invention belongs to the technical field that External Wall in the floor construction body process adds lagging casing, relate to a kind of external wall outer insulation site construction technology based on ultra-light foaming cement material.
Background technology
The technical task of putting on " warming coat " to construction wall is scintillating the building trade personage's.Increasing building adopts and carries out the thermal-insulating waterproof construction, and the employing heat preservation plate material that has is in the mode that exterior wall pastes, the form that the employing that has is directly smeared at exterior wall, and the present invention mainly is for on-the-spot technique of constructing on exterior wall.Because the good heat insulating of foamed cement material, and reach the fireproof effect, therefore adopting foamed cement material is an extraordinary behave as heat preservation core layer, but traditional foam cement mostly is greatly following form to the casting method in the body of wall: 1, the two sides is masonry, the middle cavity that forms, pouring foaming cement in the cavity; 2, template has been propped up on the two sides, forms cavity in the template, pouring foaming cement in the cavity; 3, the one side formed body of wall, formwork supporting plate body of wall outside, to formation cavity in pouring foaming cement.More than three kinds of forms all need to rely on ground or scaffold support, must scaffold erecting first during construction.It is loaded down with trivial details to construct, and efficient is lower, especially needs to remove scaffold after exterior wall forms, and uses afterwards the difficulty of formwork supporting plate larger, and construction is inconvenient.Therefore be badly in need of and study the problem of insulation and waterproof site operation.
Summary of the invention
The invention provides a kind of external wall outer insulation site construction technology based on ultra-light foaming cement material, solve the large technical barrier of formwork supporting plate difficulty in the prior art, a kind of mould and whole work progress of new-type pouring foaming cement material have been designed, need not the support of ground or scaffold, both reduce the difficulty of formwork supporting plate, saved the working time, implanted again stressed bolt, heat insulation system firmly is connected with side fascia, has realized killing two birds with one stone.
The present invention realizes that the technical scheme that goal of the invention adopts is, based on the external wall outer insulation metope site construction technology of foamed cement material, is included in the processing step of directly making heat preservation core layer and waterproof layer on the exterior wall, and concrete steps are:
A, make the first mould of strip grooved and with flat board as the second mould, for subsequent use;
B, take ground as basal plane, on exterior wall according to the first die horizontal cross direction profiles, vertical location require form the unit grid in the hanging wire side of drawing;
C, in each unit grid, respectively in the punching of the above and below of the first mould pre-determined bit, and by reinforcing bar planting material implanted metal bolt;
D, the first mould is withheld on the exterior wall end face, compressed by compressing steel plate, and position by locking nut;
E, in the first mould pouring foaming cement based slurry, form the heat insulation inner core cushion block after the sclerosis, and remove the first mould;
F, the second mould is positioned between the end face of upper and lower adjacent two heat insulation inner core cushion blocks by locking nut and metal bolts;
G, in the space that forms between the second mould and two the heat insulation inner core cushion blocks pouring foaming cement based slurry again, after the sclerosis and heat insulation inner core cushion block and metal bolts shape all-in-one-piece heat preservation core layer structure, and remove the second mould;
H, smear the compression polymer cement mortar in heat preservation core layer, form waterproof layer after the sclerosis;
I, along continuous straight runs extension arrange the first mould, re-cover execution in step c-h until reach the border of design and construction;
J, established insulation layer are that the bottom surface re-covers the b-i step heat insulation inner core pad is extended upward until reach the height of design.
The bolt of some is implanted in the present invention's perforate on outer wall body, fixes two kinds of templates with it, and bolt is connected with wire lath in the anti-cracking waterproof surface layer, the main stress point that carries as heat insulation system.Take on ground as basal plane, two kinds of masterplates are adopted interval cross bearing mode, at first positioned at intervals the first template as pedestal, is positioned at cast foam cement well on the interval with the second template overlap joint again, and final cast forms heat preservation core layer.Need not to set up scaffold, greatly increase work efficiency.The metal bolts of utilize implanting, and postorder cement nail or the expansion bolt squeezed into have been strengthened the support force of insulation and waterproof construction greatly.
The present invention is described in detail below in conjunction with accompanying drawing.
