External thermal-insulation wall of mechanical anchoring gridding reinforcing rib inorganic modified foam thermal-insulation board

Abstract

The invention discloses an external thermal-insulation wall of a mechanical anchoring gridding reinforcing rib inorganic modified foam thermal-insulation board. The external thermal-insulation wall is sequentially composed of a base layer wall body 4, a leveling and binding layer 5, a gridding reinforcing rib inorganic modified foam thermal-insulation board 6, plastic expansion anchor bolts 7, a thin troweling protective surface layer 8 and a surface detective layer 9 on the base wall body from inside to outside. The external thermal-insulation wall is characterized in that the leveling and binding layer 5 is adopted to bond the base layer leveling and the gridding reinforcing rib inorganic modified foam thermal-insulation board 6 in an auxiliary mode in one step, the bonding is only used for ensuring planeness during installation of an external thermal-insulation system, then the plastic expansion anchor bolts 7 are used for anchoring the gridding reinforcing rib inorganic modified foam thermal-insulation board 6, and all loads of the external thermal-insulation system are enabled to completely borne by the plastic expansion anchor bolts 7 and are directly transferred to the base layer wall body 4. Through combination of the gridding reinforcing rib inorganic modified foam thermal-insulation board 6 and the plastic expansion anchor bolts 7, tensile strength, anti-bending strength and stability of a thermal-insulation layer are largely improved.

Description

Technical field [0001] The invention relates to an external thermal insulation wall body of an external wall with a mechanical fixing device anchoring a grid reinforcement inorganic modified foam thermal insulation board, and is especially suitable for an energy-saving renovation project of an existing building external wall. Background technique [0002] The existing inorganic modified foam insulation board external insulation wall is a composite wall composed of the building exterior wall as the base wall and the inorganic modified foam insulation board. The inorganic modified foam insulation board is used as the insulation layer with an adhesive Fixed on the base wall. This structure requires the adhesive to bear all the loads of the external thermal insulation system, and at the same time transfer all the loads to the base wall through the wall leveling layer. However, due to the unevenness of the base layer of the building wall or the insulation board, the thermal insu...

Problems solved by technology

[0004] In order to overcome the disadvantages that the existing inorganic modified foam insulation board of the external thermal insulation wall may produce virtual sticking and hollowing by the method of bonding and fixing, and at the same time overcome the stability of the existing inorganic modified foam insulation board when the mechanical fixing device is anchored. Poor defect, the present invention provides a kind of external thermal insulation wall body that adopts plastic expansion anchor bolt of mechanical fixation device to anchor grid reinforcement inorganic modified foam insulation board, and its grid reinforcement inorganic modification foam insulation board is made of inorganic modified foam The thermal insulation board is composed of two-way grid reinforcing ribs sandwiched in its surface layer. It is characterized in that: the outer surface of the two-way grid reinforcing ribs is attached with a protective layer of inorganic modified foam thermal insulation board, which can improve the performance of inorganic modified foam thermal insulation board. The tensile strength, bending strength and flexural strength of the inorganic modified foam insulation board can enhance the mechanical properties and overall stability of the external insulation system of the inorganic modified foam insulation board; the inorganic modified foam insulation board is an inorganic modified polystyrene organic foam insulation board, inorganic Modified polyurethane organic foam insulation board, inorganic modified polyurethane-polyisocyanurate organic foam insulation board or inorganic modified phenolic organic foam insulation board

The mechanical anchoring of the external thermal insulation wall can not only solve the problem of difficult inspection and maintenance of the bonded virtual glue, but also stabilize and reinforce the original decorative structure layer of the old base of the existing building; in addition, The construction process is simple and fast
