Description
Technical field
The present invention relates to building field, specifically a kind of building heat preservation construction technology.
Background technology
Along with society is constantly progressive, sustained economic growth and builing industry flourish, the present situation of inadequate resource is more outstanding, energy-conserving and environment-protective consciousness more and more causes the concern of society and government." building energy conservation engineering construction standards of acceptance " policy such as (GB50411-2007) also shown the attention of governments at all levels to building energy conservation work to the relevant requirements of energy conservation.Wall thermal insulating is to realize an energy-conservation important way, the prior art wall insulation system can not satisfy requirements of saving energy fully, long construction period, economic benefit is not remarkable, main is the wall insulation system of prior art, exists cold bridge phenomenon, can't guarantee energy-saving effect, and take indoor usable floor area, influence the interests of resident family.Also there is the minority construction unit to implement external wall outer insulation technology at present, but all is rearmounted method operation, be i.e. just can carry out the enforcement of heat preservation method after the main body completion, so the time-consuming input of taking a lot of work of this kind technology is many.
Summary of the invention
For solving the problem that prior art exists, the invention provides the external wall outer insulation construction technology that a kind of duration is short, cost is low.
The present invention is achieved in that
A kind of external wall outer insulation construction technology comprises the steps:
Extruded polystyrene board is processed into required size, and the extruded polystyrene board medial surface is split into the dovetail groove of horizontal direction, in dovetail groove inner surface spray interfacial agents;
The body of wall reinforcing bar binding is installed the reinforcement cover cushion block;
Extruded polystyrene board is good according to the wall size spelling, seam is obturaged with adhesive tape, to have the plate face of horizontal dovetail groove towards the shear force wall reinforcing steel bar rack, in place according to the flooring unwrapping wire, with wire extruded polystyrene board and shear force wall reinforcing steel bar frame are connected together again, inboard large form is installed, and the exterior wall hole to be provided is kept somewhere the back inboard large form is installed;
Adjust and reinforce, seal side plate;
Check and accept, after the acceptance(check), with concrete pouring in mould;
After the concrete setting template is dismantled, the dirt on cleaning extruded polystyrene board surface also carries out local equating;
On extruded polystyrene board, brush interfacial agents;
On extruded polystyrene board, smear the bottom antimitotic agent, then plastering mortar, paving alkali resistant glass fibre open weave cloth;
Then float coat antimitotic agent and facing sand slurry, putty at the bottom of the brushing elasticity, scrape the fine and smooth son of flexible waterproof;
Adopt coatings decoration at last.
As a preferred embodiment of the present invention, described dovetail groove groove depth can be 8～12mm, the wide 45～55mm that can be of groove collar extension, the wide 65～75mm that can be of groove internal orifice.
As another kind of preferred version of the present invention, before big mould outside plate is installed, at shear force wall reinforcing steel bar rack upper and lower side several circular orientation cards are set in advance.
As the present invention further optimization scheme, described circular orientation card can adopt plastics to make.
As another preferred version of the present invention, can adopt the electrical heating metal bar to aim at manned inboard large form bolt hole extruded polystyrene board is bored a hole, then split bolt is penetrated in the hole, extruded polystyrene board is fixedlyed connected with the medial and lateral large form.
The present invention's extruded polystyrene board is provided with horizontal dovetail groove, has improved the snap-in force of cast-in-situ concrete and insulation extruded polystyrene board, has increased extruded polystyrene board and concrete bond area, has overcome construct bonding space bigger shortcoming of rearmounted method; Extruded polystyrene board presets have been realized constructing synchronously with major project, has shortened the follow-up duration, thereby has avoided rearmounted method to adopt the bracketplant construction to cause the problem of security incident easily simultaneously; The brushing interfacial agents has realized the effectively bonding of extruded polystyrene board and concrete or antimitotic agent etc., has saved adhesivess such as a large amount of dry powder; No steel wire net rack system has effectively been eliminated consequent heat bridge, greatly reduces the cost between construction and operating period.
Before the big institute in outside template is installed, set up some plastic annular locator cards at shear force wall reinforcing steel bar rack upper and lower side in advance more, fully closely connected to guarantee extruded sheet and big mould outside plate, so just, guaranteed the verticality and the planeness of extruded sheet, can prevent that the mix material from sealing between extruded sheet and the big mould outside plate.
Adopt electrical heating metal bar (diameter is identical with the bolt aperture) to aim at manned large form bolt hole extruded polystyrene board is bored a hole, can prevent to damage extruded polystyrene board, thereby guarantee that extruded polystyrene board upper bolt hole size to fit position is accurate.
The present invention has easy construction, safety, and heat insulation effect is good, and social and economic benefits and good has reached effect in energy saving and environmental protection.
