External wall thermal insulation dual-purpose board core

Abstract

The invention relates to the technical field of external wall thermal insulation dual-purpose board cores, in particular to an external wall thermal insulation dual-purpose board core. The external wall thermal insulation dual-purpose board core comprises a thermal insulation board core body, wherein a plurality of parallel dovetail grooves and a plurality of inner through holes are evenly formed in the thermal insulation board core body at intervals. Due to the fact that the parallel dovetail grooves and the inner through holes are evenly formed in the thermal insulation board core body at intervals, the dovetail grooves can be utilized for enabling mortar and the thermal insulation board core body to be solidified integrally. Due to the fact that the dovetail grooves are wide in interior and narrow in exterior, the contact area of the mortar and the thermal insulation board core body is large, so that the thermal insulation board core body does not easily swell or deform or fall off and is not easily layered. Due to the fact that the inner through holes are formed, when electric wires are installed in the floor, the electric wires are threaded into the holes, a wire channel does not need to be additionally formed, and with the inner through holes, usage of raw materials can be reduced, and production cost is reduced. Compared with a solid core board, due to the fact that the inner through holes are formed, the energy-saving effect of a building is correspondingly increased.

Description

technical field [0001] The invention relates to the technical field of board cores for thermal insulation of external walls, in particular to a dual-purpose board core for thermal insulation of external walls with dovetail grooves and internal through holes. Background technique [0002] Existing buildings that fail to meet the energy-saving standards shall undergo energy-saving renovations, and a layer of insulation boards shall be pasted on the outside, and external insulation layers shall be installed on the outer walls of buildings under construction if the energy-saving standards do not meet the energy-saving standards. "Steel wire frame molded polystyrene board for external wall insulation system" is the national standard GB26540-2011 of the People's Republic of China. The diameter and performance of steel wire for external wall insulation system have been listed as mandatory standards. The external insulation performance is fully supported by molded polystyrene panels...

AI Technical Summary

Problems solved by technology

[0003] The object of the present invention is to provide a dual-purpose panel core for external wall insulation with dovetail grooves and internal through holes in order to overcome the shortcomings of the prior art, aiming to solve the problem that the existing polystyrene insulation panel core is solid. There is no internal through hole, there is no technical problem that can maximize the energy-saving effect of the polystyrene board and open another line when installing the wire, which is labor-intensive, time-consuming and material-intensive.
