Device capable of increasing laying quality of external wall insulation boards and construction method

Abstract

The invention relates to a device capable of increasing the laying quality of external wall insulation boards. The device is characterized in that a cross stiffening rod is arranged on an inner wall support plate, an insulation board inner baffle is arranged on the cross stiffening rod, a connecting rod guide pipe is arranged on the insulation board inner baffle, and a connecting rod is inserted into the connecting rod guide pipe; adjusting screws are connected to both sides of the insulation board inner baffle, an insulation board outer baffle is arranged on the adjusting screws, and nuts areinstalled on the ends of the adjusting screws; the distance between the insulation board inner baffle and the insulation board outer baffle is equal to the thickness of an insulation board; the distance between the inner wall support plate and the insulation board inner baffle is equal to the thickness of a shear wall; and the lengths of the two adjusting screws which extend out of the insulationboard outer baffle are equal. A construction method comprises the steps of placing the device on a to-be-poured wall; inserting the connecting rod into the connecting rod guide pipe; installing two insulation boards; pouring concrete; removing the insulation board outer baffle and the connecting rod; repeating the steps till the pouring of a shear wall body is finished; and cutting the exposed adjusting screws. According to the device and the construction method, the problems of flatness and no damage to the abutted seam of the insulation boards can be solved, and the section size of the shear wall is guaranteed.

Description

technical field [0001] The invention relates to the field of building construction and a construction method thereof, and specifically belongs to a device and a construction method capable of improving the laying quality of external wall insulation boards. Background technique [0002] At present, the external thermal insulation construction of the cast-in-place wall is to first stick the thermal insulation board on the outer wall of the structure with adhesive mortar, then fix the thermal insulation board on the outer wall through the connector, and then apply mortar paint on the thermal insulation board. Its disadvantages are: complex process, high difficulty in construction, time-consuming, heavy on-site workload, and poor bonding stability between the outer insulation layer and the wall, which will cause potential safety hazards of falling off. Especially for the construction of high-rise buildings, it is very easy to cause serious personal injury accidents. For the lay...

Problems solved by technology

Its disadvantages are: complex process, high construction difficulty, labor and time-consuming, heavy on-site workload, and poor bonding stability between the outer insulation layer and the wall, which will cause safety hazards of falling off

Its shortcomings: the processing, transportation and storage of insulation boards with embedded parts are more difficult; cutting phenomenon is inevitable during on-site splicing, but the tongue-and-groove cannot be guaranteed after cutting; the insulation hidden inside the formwork when the insulation board is reinforced The position of the slab is not easy to ensure, which affects the section size of the shear wall and cannot be reused

Its shortcomings: the prefabrication period is long, and the on-site storage space is large; its structure is self-heavy, and it has high requirements for lifting and hoisting. It is inconvenient for manual operation during installation, and it is easy to cause damage to the decorative layer; the device has no vertical connection When the device is applied to the structural exterior wall of a high-rise building, it is difficult to meet the seismic requirements; the device has high requirements for the detailed design of the drawing, and all components of the tourmaline are processed and manufactured strictly according to the size of the demolition drawing, which is difficult to manufacture

Its shortcomings: the structure of the device, especially the conical plate, is complex, and the prefabrication process is difficult; the insulation board with the decorative surface and the positioning plate of the device is a shaped component, and its slideway and positioning groove will be destroyed during on-site processing, and the design splicing cannot be completed Solution; when the embedded parts are fixed to the wall, holes need to be precisely opened in the wall, otherwise the embedded parts cannot be anchored into the wall
