Decoration and heat insulation external building block structural system

Abstract

The invention discloses a decoration and heat insulation external building block structural system, which is characterized by consisting of eight block types of decoration and heat insulation external building blocks, namely a main block, a half block, an external corner block, an internal corner long main block, an internal corner long half block, an internal corner main block, an internal corner half block and a cornice external block, wherein except the cornice external block, each of the other seven block types is formed by compositing a heat insulation board 1, a concrete protection layer 2 and a decoration surface layer 3; a plurality of vertical dovetail grooves 5 and one horizontal dovetail groove 4 are formed on one large face of the heat insulation board 1, and a sign-shaped groove 6 is formed on the other large face; each edge of the heat insulation board 1 is protruded from the concrete protection layer 2 about 5 millimeters in the horizontal direction and 10 millimeters in the vertical direction; a plurality of concrete protection layers 2 form a dust gap of which the width is about 10 millimeters; anti-cracking mortar is filled in the dust gap; and a plurality of heat insulation boards 1 are connected mutually so as to stop a cold bridge of the building blocks. The decoration and heat insulation external building block structural system has the characteristics that: a decoration effect and a heat insulation effect are integrated, and the heat insulation material and the building have the same service life.

Description

technical field [0001] The invention relates to a new type of building exterior wall thermal insulation structure system, in particular to a decorative thermal insulation externally pasted block construction system pasted and anchored on the external surface of the building's outer retaining wall. Background technique [0002] In order to save energy and realize the strategic policy of sustainable development, the Chinese government enforces energy-saving buildings, and the energy-saving standard is raised from the original 50% energy-saving to 65% energy-saving. At present, the main ways of building energy conservation in my country are: external wall insulation, which are mainly "rubber powder polystyrene particle external wall external insulation system" and "polystyrene board thin plaster external wall external insulation system", due to the climate in the north and south The difference is very large, and there are quite a lot of problems exposed. The main manifestations...

AI Technical Summary

Problems solved by technology

[0003] The present invention is trying to solve the problems existing in the current external thermal insulation system of external walls such as cracking and falling off of the thermal insulation layer, easy fires during construction, poor durability, thermal insulation materials that cannot last the same life as the building, and secondary decoration.
