Description

Polystyrene Composite Insulation Wall Panel Double Leaf Exterior Wall

technical field

The utility model relates to a new type of building wall material - a double-leaf outer wall of a polystyrene composite thermal insulation wallboard.

Background technique

In order to develop energy-saving buildings in my country's current residential construction, the outer wall of the building must have multiple functions such as thermal insulation, heat insulation, and sound insulation. In recent years, in energy-saving buildings, it is generally used to paste polystyrene boards or polystyrene particles on the outer surface of the building's outer walls to achieve thermal insulation effects. From the practice of external wall insulation for several years, these two There are many technical defects and quality problems in the insulation methods, the most prominent are the cracking of the insulation layer, poor impact resistance, and poor durability. On the basis of the original energy saving of 50%, the government has proposed to implement an index of 65% energy saving. The current two external insulation methods have encountered some insurmountable difficulties. In order to adapt to the development of frame structure and steel structure, polystyrene composite insulation wallboard double-leaf exterior wall is proposed, which can effectively solve the problems of cracking and poor durability of the external insulation layer of the exterior wall, and can meet higher standards of energy-saving requirements.

Utility model content

The purpose of the utility model is to overcome the problems of cracking and poor durability of the outer insulation layer of the outer wall of the existing building, and provide a double-leaf outer wall of polyphenylene composite insulation wallboard with high thermal insulation performance. The technical scheme of the utility model is realized in the following way: a double-leaf outer wall of polyphenylene composite thermal insulation wallboard, comprising an inner leaf wall 1, an air interlayer 2 and an outer leaf wall 3, wherein the outer leaf wall 3 is made of a protective panel 4 It is composed of thermal insulation wall panels compounded with thermal insulation board 5; on the two large surfaces of thermal insulation board 5, grooves in the shape of a "well" grid are evenly processed, so that thermal insulation board 5 and protective panel 4 are organically firm. Bonding, at the same time, several small-diameter through holes are evenly processed on the two large surfaces perpendicular to the insulation board 5, so as to form cement mortar tie bars 6, and the protective panel 4 and the insulation board 5 are tightly and firmly connected into a whole, Increase the rigidity of the outer leaf wall 3; the protective panel 4 of the outer leaf wall 3 is prepared with concrete, in which two layers of alkali-resistant high-strength glass fiber mesh cloth are laid to enhance the impact resistance; the two layers of the insulation board 5 in the outer leaf wall 3 There is a rectangular groove on each long and small surface, and the polystyrene composite thermal insulation wall panels are connected by high-density thermal insulation beading with a cross-section of "ten"; the joints between the protective panels 4 are grooved with anti-crack mortar to prevent external The leaf wall is cracked to improve durability; the air interlayer 2 plays the role of sound insulation, fire prevention and thermal insulation; the inner leaf wall 1 can be masonry made of perforated bricks, hollow blocks, and strip plates; the outer leaf wall is installed first 3. Post-build the inner leaf wall 1.
