Abstract

The purpose of this utility model is to provide an energy-saving building external protection structure composite thermal insulation wall, which is suitable for the external wall insulation layer and thermal insulation wall structure of small-scale buildings, including the base wall, and the outer side of the base wall is an outer partition Thermal insulation material, the outer surface of the external thermal insulation material is paint or brick or stone; the inner thermal insulation material is used in the base wall, and the inner protective layer of the inner thermal insulation material is a mortar cover. The utility model adds internal thermal insulation on the basis of external thermal insulation of the external wall to form a composite thermal insulation wall with double-sided thermal insulation. This structure can avoid the same shape coefficient, window-to-wall ratio, and a small building unit that only adopts external thermal insulation and cannot meet energy saving requirements. Questions about design requirements. For small-scale buildings, it can reduce the problems of construction difficulty and uneconomical cost caused by excessive thickness of insulation materials for external wall insulation. Among them, solving the problem of construction difficulty is particularly prominent.

Description

Energy-saving architecture external enclosing and protective structure composite heat preservation wall

Technical field:

The utility model relates to a kind of thermal insulation structure of building external, especially a kind of energy-saving architecture external enclosing and protective structure composite heat preservation wall.

Background technology:

The external wall insulating layer of at present extensive use mainly is comprised of base course wall and external insulation material, but this structure spininess is larger to the scale of construction, the big-and-middle-sized public building that Shape Coefficient is less, civilian construction etc.This type of building is because the ratio of external surface area and volume is less, and the area and the own vol that namely contact with outdoor air are smaller, so energy saving calculation is easier to satisfy the current specifications requirement.

But just present construction market, singly be that big-and-middle-sized building monomer can not the satisfying the market requirement, the building of small volume is villa for example, and the ratio that has also occupied the construction market considerable part take auxiliary function as main small volume building, this type of small volume building also is badly in need of a kind of exterior wall insulated structure that is fit to this architectural mode and characteristics.

Summary of the invention:

The purpose of this utility model is to provide a kind of insulating layer of external wall and heat-insulating wall structure that is applicable to the small volume building.

A kind of energy-saving architecture external enclosing and protective structure composite heat preservation wall comprises base course wall 4, is outer heat insulation materials 5 in base course wall 4 outsides, and outer heat insulation material 5 outer cover are coating or face brick or stone material; Be inner heat insulation material 3 in the base course wall 4, the inboard topping of inner heat insulation material is the mortar cover.

Described base course wall 4 is the mixed load-carrying members base course wall of brick or frame wall filled with masonry structure base course wall.

The mineral wool board, rock cotton board, hard polyurethane foam plate etc. of described inside and outside heat-insulating heat-preserving material 3,5 for having high thermal property and fireproof performance.

The direction that described inside and outside heat-insulating heat-preserving material 3,5 is away from base course wall 4 separately also can arrange inboard topping 2 and outside topping 6; this topping is built by laying bricks or stones by clinker brick or building block and mortar; wherein with adhesive powder-polystyrene granule thermal insulation mortar as leveling layer, to be embedded with polymers anti-cracking mortar that alkali resistant glass fibre open weave cloth strengthens as overcoat.

The utility model is incubated in thermal insulation foundation increases outside exterior wall, form the composite thermal-insulating wall of double side insulation, this structure can avoid that small volume building monomer only adopts outer insulation can not satisfy the problem that energy-saving design requires under same Shape Coefficient, the window-wall ratio.For small volume building, can reduce the problems such as difficulty of construction that external wall outer insulation only causes because heat insulating material is blocked up and cost be uneconomical, wherein, the problem that solves difficulty of construction is particularly outstanding.Following table is that the pluses and minuses to the various indexs of inside and outside insulation and outer insulation compare:

Fig. 1 is the structural representation of a kind of embodiment of the utility model.

Wherein, the 1st, indoor facing layer, the 2nd, inboard topping, the 3rd, inner heat insulation material, the 4th, base course wall, the 5th, outer heat insulation material, the 6th, outside topping, the 7th, outdoor finish coat.

The specific embodiment:

The Specific construction flow process is as follows:

1. after base course wall is finished construction, should process smooth solidly, projection can not be arranged, metope can not influential bonding pollutant, accomplishes that the metope cleaning is clean;

2. after body of wall cleans out, should at first finish the installation of heat insulating material for external, the bonding adhesive, the installation crab-bolt that are used for heat insulating material for external should satisfy various technical requirementss, and be crucial for bearing the load in each layer of exterior wall structure;

3. when heat insulating material was laid, it was temporary fixed in place with plate of material to use anchoring piece, and take the rock cotton board of modal 1200x600mm specification as example, every bulk flitch should have 2 anchor points at least, and the plate seam answers jam-packed not interspace; The fillet width that is embedded into usefulness must not and have an anchor point at least less than 150mm, along 3 anchor points in the every at least limit of door and window hole;

4. when plate of material instead is intended to improve the surfacing of surface strength, waterproof and adhesive property, all should be after plate of material and gauze wire cloth install and fix, to plate face spraying sand interfacial agents;

5. plate of material is smeared heat preservation slurry and is mainly played the levelling effect;

6. before anticracking grout was wiped one's face, at the additional alkali resistant glass fibre open weave cloth of hole four corners position paving, the construction of this overcoat should be carried out after the heat preservation slurry leveling layer fully solidifies, and according to facade and material requirements partitioning slot is set;

7. can carry out interior heat preservation construction after construction of exterior insulation system is finished, in addition, interior insulation must delivery receiving acceptance be complete respectively in roof waterproof layer and Structural Engineering, and erection of doors and windows is complete, water power and decorate and pre-buriedly can construct after complete;

8. interior heat preservation construction is sequentially installed warming plate → smear door and window mouth corner protector → stickup grid cloth → Puttying → facing for metope cleaning → snap the line → smear floating screed point → stickup.
