Technical Field

The invention relates to the field of building construction and a construction method thereof, and particularly belongs to a device and a construction method capable of improving the laying quality of an external wall insulation board.

Background

At present, the external thermal insulation construction of a cast-in-place wall body is that a thermal insulation board is firstly adhered to the outer wall surface of a structure by using adhesive mortar, then the thermal insulation board is fixed on the outer wall body by a connecting piece, and then mortar paint and the like are coated on the thermal insulation board. The defects of the method are as follows: the process is complex, the construction difficulty is high, the labor and the time are wasted, the workload of field operation is large, the firmness and the stability of the bonding between the outer heat-insulating layer and the wall body are poor, and the falling potential safety hazard can be generated. Especially for the construction of high-rise buildings, serious personal injury accidents are easy to cause. For the internally laid insulation board, only single-room construction can be adopted, the construction time is long, more importantly, the indoor space can be reduced, and the use efficiency of the house is directly influenced.

In order to solve the above-mentioned defects, the person skilled in the art develops and innovates the integrated non-demolition external wall insulation system. When the non-dismantling heat insulation plate is constructed, a plurality of reinforcing methods are provided, and the most common method is to open holes on the non-dismantling template by an external template and to penetrate split bolts for fixing. The method has the defect that the flatness of the joint of the heat-insulation board is difficult to ensure in the process of reinforcing the split bolt. Concrete spreader bar in ordinary construction because it is little with heated board foundation area, can lead to bursting the phenomenon of heated board during the construction, therefore the condition that makes outer heat preservation excursions, the cross-sectional dimension that leads to the shear force wall like this diminishes, and concrete placement accomplishes the back, and this kind of cross-section diminishes and hardly detects out, and the change of outer wall cross-section is great to the shock resistance performance and the whole atress influence of structure.
