Abstract
The invention discloses an external thermal-insulation wall made of mechanically-anchored grid reinforcing rib rockwool panel and a construction process. In the invention, a leveling and binding layer on a base wall is used to bind the thermal-insulation grid reinforcing rib rockwool panel on the wall before drying and thus plays a role in connection assistance and stabilization and guarantees the evenness of the rockwool panel; and then, holes are drilled on the panel for fixing the grid reinforcing rib thermal-insulation rockwool panel on the base wall directly by using plastic expansion anchor bolts, so that all loads of an external thermal-insulation system can be withstood by the fixing anchor bolts and transmitted to the base wall. The organic combination of the anchor bolts and the reinforcing rib rockwool panel also can assist in the stabilization of load of the leveling layer of the base wall. Therefore, the external thermal-insulation wall and the construction process are particularly suitable to be used in the conventional building external wall thermal-insulation and energy-saving reconstruction projects and well solve the technical problems of low load bearing performance of the original base layer of an external wall and difficult surface treatment.
Description
Affiliated technical field
The present invention relates to a kind of external wall outer insulation body of wall and construction technology of mechanical fastening system anchored grid reinforcing rib rock cotton board, be particularly useful for the reducing energy consumption engineering of existing building exterior wall.
Background technology
Existing mechanical anchoring rock cotton board external heat insulating wall is the combined wall that is combined by basic unit's body of wall and rock cotton board.Because of the tensile strength and the rupture strength of rock cotton board lower, generally be to adopt gauze wire cloth to carry out the surface to strengthen, this structure requires when fixing rock cotton board, gauze wire cloth must and the rock cotton board surface between add pad, make to have certain distance between gauze wire cloth and the rock cotton board; With anchoring piece gauze wire cloth and rock cotton board directly are fixed on the structure wall the thick leveling layer of 20mm of putting on powder in the gauze wire cloth both sides then simultaneously.
But because the peel strength of rock cotton board is lower, the way of above-mentioned increase leveling layer will directly cause the load of heat preservation rock plate surface layer to increase, defectives such as the off normal that easily produces of gauze wire cloth site operation and out-of-flatness in addition, may give whole external heat insulating wall, stay the hidden danger of quality and security and stability.Therefore, be necessary to improve the fixing means of heat preservation rock plate.
Summary of the invention
Adopt anchoring piece and gauze wire cloth fixing means may produce the deficiency of quality and security and stability hidden danger in order to overcome existing mechanical anchoring rock cotton board external heat insulating wall, the invention provides a kind of external heat insulating wall and construction technology with mechanical device anchored grid reinforcing rib rock cotton board, this external heat insulating wall can not only solve increases the quality that the leveling layer load may cause and the problem of security and stability, and can significantly improve the tensile strength and the rupture strength of rock cotton board.In addition, construction technology is simple, quick.
The technical solution adopted for the present invention to solve the technical problems is: at basic unit's surface of wall, completely criticize polymer mortar as the levelling setting course of holding concurrently, with accompanying the rock cotton board of two-way grid reinforcing rib in the top layer, be adhesive on the wall immediately simultaneously, guarantee the planeness of rock cotton board.As required, the material of grid reinforcing rib is bidirectional glass fiber net, metallic steel silk screen or chemical fiber web.In the boring plastic expansion crab-bolt of plate face gridding strengthening rib rock wool board directly is fixed on the base layer structure body of wall then.Protect surface layer anticracking grout and roller coating facing coating elastic coating thin the smearing of external surface of gridding strengthening rib rock wool board at last.
The thickness of above-mentioned levelling setting course polymer mortar is 3～9mm, satisfies the needs of levelling and bonding thickness.The spacing of the mechanical fastening system plastic expansion crab-bolt that above-mentioned vertical, horizontal is arranged in parallel is 200～450 * 200～450mm, optimal spacing is 250～400 * 250～400mm, every square metre 〉=8 of crab-bolt quantity, effective anchorage depth 〉=25mm of crab-bolt, best anchorage depth are 35～45mm; Crab-bolt diameter 〉=8mm, single crab-bolt tension standard value of bearing capacity 〉=0.6KN, the plastic disc small opening pressing plate diameter 〉=60mm of crab-bolt outer end is to guarantee the stability of warming plate.
The external heat insulating wall of above-mentioned mechanically-anchored grid reinforcing rib rock cotton board and construction technology is characterized in that construction technology comprises following processing step:
(1) completely criticizing thickness on basic unit's metope is the polymer mortar levelling of the 3～9mm setting course of holding concurrently;
(2) be adhesive on the wall with the heat preservation rock plate that is about to accompany in the top layer two-way grid reinforcing rib, form the tight insulation layer;
(3) treat to hole at the plate face behind the adhesion strength 〉=0.06MPa of levelling setting course mortar, bore diameter should be identical with the crab-bolt diameter specifications, the plastic expansion crab-bolt of mounting end band plastic disc small opening pressing plate directly is fixed on grid reinforcing rib heat preservation rock plate on basic unit's body of wall then;
(4) approach plaster protection surface layer anticracking grout and the construction of finish coat elastic coating at last.
Beneficial effect of the present invention: adopt the fixing external heat insulating wall of anchoring piece and gauze wire cloth to compare with existing rock cotton board, basic unit's levelling and the auxiliary stickup of warming plate once can be finished, reduce working procedure and duration; Adopt mechanical fastening system anchored grid reinforcing rib rock wool heat-preservation plate, construction technology is simple, easy to operate, and construction quality is easy to control; The combination of this gridding strengthening rib rock wool board and crab-bolt has improved tensile strength, rupture strength and the stability of insulation layer greatly.The present invention is particularly useful for the reducing energy consumption of existing building external wall outer insulation; can solve effectively because of the adhesion strength defect of insufficient that flake in the part of the old basic unit of body of wall, crackle or surface contamination barrier film etc. bring; can play a reinforcement, protective effect to original basic unit, improve its stability.
