Summary of the invention
The object of the present invention is to provide a kind of have generally apply meaning; Assemble the external thermal insulation system that forms by small-sized insulation precast plate; Replace existing paste heat-preserving plate thinly plastered external insulation system of outer wall, thereby solve the various technical problems that existing paste heat-preserving plate thinly plastered external insulation system of outer wall exists.
For realizing the foregoing invention purpose, the technical scheme that the present invention takes is following:
A kind of external thermal insulation system that is formed by small-sized insulation precast plate assembling is characterized in that:
1, small-sized insulation precast plate is made up of fine concrete panel and warming plate two parts, is furnished with gauze wire cloth in the said fine concrete panel, around the upper and lower, left and right greater than the fine concrete panel around the upper and lower, left and right of gauze wire cloth;
Said fine concrete panel medial surface is provided with the fine concrete tenon of vertical protrusion by suitable spacing, and fine concrete tenon and fine concrete panel are solidified as a whole; The cross sectional shape of fine concrete tenon is square or circular; The termination of fine concrete tenon is fixed with the insulation cushion block; Be provided with the holdfast hole perpendicular with the fine concrete panel in the fine concrete tenon, formation holdfast head of a nail counterbore is strengthened at the appropriate depth scope internal orifice dimension of fine concrete panels outside face one end in the holdfast hole; The thickness sum of the height of projection of fine concrete tenon and insulation cushion block equals the thickness of warming plate;
The length and width size of said warming plate is greater than the length and width size of fine concrete panel; Warming plate has mortise at the correspondence position with the fine concrete tenon; The method that warming plate adopts the fine concrete tenon to insert in the mortise is fastened on fine concrete panel inboard; Around the upper and lower, left and right greater than warming plate around the upper and lower, left and right of gauze wire cloth, around the upper and lower, left and right greater than the fine concrete panel around the upper and lower, left and right of warming plate;
2, small-sized insulation precast plate adopts holdfast to pass the mode that the holdfast hole anchors in basic unit's body of wall and is connected and fixed on basic unit's body of wall outer wall, and the holdfast head of a nail and head of a nail pad sink in the holdfast head of a nail counterbore, and head of a nail pad employing steel plate washer or steel plate washer add rubber sheet gasket;
3, small-sized insulation precast plate adopts opposite joint to arrange (being horizontal joint and hard vertical masonry joint all align) or fissure of displacement arrangement in the arrangement of basic unit's body of wall outer wall; Adjacent warming plate is close to each other, and the gauze wire cloth of adjacent fine concrete panel overlaps each other;
4, the gauze wire cloth overlapping the slot of small-sized insulation precast plate assembling arrangement formation is tamped floating with dedicated mortar;
5, when basic unit's body of wall outer wall adopts the gross area plaster leveling, the construction technology step that small-sized insulation precast plate assembling forms external thermal insulation system is:
1) basic unit's body of wall outer wall plaster leveling;
2) specification and the arrangement mode according to warming plate ejects row's plate frame bar at basic unit's body of wall outer wall, and emits holdfast anchor point bore position line (than boring aperture big slightly circle or round dot) in each lattice piece:
3) hole on basic unit's body of wall according to holdfast anchor point bore position line, and in the hole, fill in the plastics crab-bolt;
4) according to row's plate frame bar in certain sequence, block-by-block is mounted on basic unit's body of wall outer wall with holdfast with small-sized insulation precast plate;
5) will assemble the gauze wire cloth overlapping the slot that forms with dedicated mortar tamps floating;
6, when adopting the point-like levelling of a levelling anchor point local location, basic unit's body of wall outer wall (promptly only smears the suitable levelling ash cake of size in the anchor point position; Plaster leveling is not made at other positions) time, the construction technology step that small-sized insulation precast plate assembling forms external thermal insulation system is:
1) eject row's plate frame bar according to the specification of warming plate and arrangement mode at basic unit's body of wall outer wall, and to emit in each lattice piece with the holdfast anchor point is the levelling ash cake position line at center;
2) according to the holdfast anchor point levelling ash cake position line, the cake of on basic unit's body of wall, plastering is done the point-like levelling;
3) on each levelling ash cake, emit holdfast anchor point bore position line;
4) hole on basic unit's body of wall according to holdfast anchor point bore position line, and in the hole, fill in the plastics crab-bolt;
6) according to row's plate frame bar in certain sequence, block-by-block is mounted on basic unit's body of wall outer wall with holdfast with small-sized insulation precast plate;
6) will assemble the gauze wire cloth overlapping the slot that forms with dedicated mortar tamps floating.
The present invention can be widely used in the various new buildings of China various places and the exterior-wall heat insulation of existing building, can solve the various technical problems that existing paste heat-preserving plate thinly plastered external insulation system of outer wall exists, and concrete beneficial effect analysis is following:
1, this is a kind of assembled integral external thermal insulation system that is formed by small-sized insulation precast plate assembling.The gauze wire cloth of fine concrete panel overlaps each other, integrant steel-wire-net reinforced concrete shell; Because insulation precast plate specification less (small-sized); The fine concrete tenon distributes closeer; Every square of holdfast supporting-point that is bearing on basic unit's body of wall is more; Thereby whole steel-wire-net reinforced concrete shell and fine concrete tenon (the comprising holdfast) supporting-point of distribution comparatively dense just constitute a support frame of stablizing solid outer insulation insulation layer, insulation layer is not stressed and exempts from the influence of extraneous adverse factor.
2, above-mentioned support frame and reinforced concrete structure are similar, have good intensity, rigidity and durability, can increase substantially the application life and the metope impact resistance of external wall outer insulation.
3, above-mentioned support frame only needs on the steel-wire-net reinforced concrete shell, to be provided with the anticracking partitioning slot of suitable spacing, just has good anticracking and water resistance, thereby has solved the anticracking and the waterproof problem of external wall outer insulation technically.
4, when warming plate adopts inorganic rock wool (or mineral wool) material; Can adopt low-cost low-density sheet material; And can reduce the outer heat insulating work cost of rock wool significantly and simplify the outer heat insulating work construction of rock wool, this for the inorganic rock wool heat insulating material that promotes good endurance and fireproof performance excellence outside exterior wall in the heat insulating work extensive use have great significance.
5, when warming plate adopts organic insulation material, because the steel-wire-net reinforced concrete shell is thicker relatively, thereby the fireproof performance ratio is pasted with organizational security temperature plate thin plastering outer heat preservation system and is significantly increased.
6, because above-mentioned support frame has good strength and stiffness, be the good basic unit of decorating surface brick, therefore this outer heat preservation system both can adopt coating ornamental surface, can adopt decorating surface brick again.
7, owing to adopt prefabrication, site-assembled technology mode can significantly reduce on-the-spot manual wet trade, greatly accelerating construction progress and reduction construction cost.
