Thus, the following detailed description of the embodiments of the present invention, presented in the accompanying drawings, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically limited otherwise.
Referring to fig. 1-3, an external wall insulation structure comprises bonding mortar 2, an XPS gypsum board 3 and a fixing anchor bolt 4, wherein the XPS gypsum board 3 is bonded on a concrete external wall 1 through the bonding mortar 2, drill holes are formed in corresponding positions of the XPS gypsum board 3 and the concrete external wall 1, the fixing anchor bolt 4 is fixed on the concrete external wall 1 through the drill holes, a glue injection hole 41 is formed in the fixing anchor bolt 4 along the axial direction of the fixing anchor bolt, a plurality of glue outlet holes 42 are uniformly formed in the side wall of the lower end of the fixing anchor bolt 4, the glue outlet holes 42 are communicated with the glue injection hole 41, and the glue outlet holes 42 are obliquely and upwards arranged; when in use, the bonding glue solution is injected into the glue injection hole 41, wherein the bonding glue solution can be bonding mortar with good fluidity; the bonding glue solution extends to the interior of the drilled hole of the concrete outer wall 1 through the glue outlet hole 42 and is dried and solidified to form a plurality of inclined strut branches, cracks at the hole positions on the wall body can be filled and repaired by the bonding glue solution, the contact area between the fixing anchor bolt 4 and the wall body is increased, the connection strength between the fixing anchor bolt 4 and the concrete outer wall 1 is increased, the fixing anchor bolt 4 is further prevented from falling off, and the installation firmness of the outer wall heat insulation structure is improved.
Further, the bonding mortar 2 is uniformly and circularly uniformly coated on the outer wall of the concrete outer wall 1, the diameter of the bonding mortar 2 is not less than 50mm, and the distance between every two adjacent bonding mortar 2 is not more than 400 mm; this kind of setting has ensured XPS gypsum board 3 and concrete outer wall 1's bonding strength, prevents dropping of XPS gypsum board 3.
Furthermore, the upper end of the XPS gypsum board 3 is tightly propped against a floor slab at the top of the concrete outer wall 1, a small base plate is arranged below the XPS gypsum board 3 to separate the XPS gypsum board from the ground, and the distance between the XPS gypsum board 3 and the ground is approximately 10-15 mm; the XPS gypsum board is prevented from being too close to the ground, and ground moisture enters the concrete outer wall 1 and the XPS gypsum board 3, so that the bonded bonding mortar 2 is loosened.
Furthermore, the distance between the fixing anchor bolt 4 and the plate edge is at least 2 times of the plate thickness and is not smaller than 100 mm; this kind of setting can avoid fixed crab-bolt 4 to strike into the time, and fixed crab-bolt 4 leads to 3 flange cracks of XPS gypsum board near too from the flange.
Further, the depth of the fixing anchor 4 driven into the wall body is not less than 40mm, so as to ensure that the fixing anchor 4 is firmly connected into the wall body.
Further, the surface of the fixing anchor bolt 4 is provided with an antirust coating; so as to prevent the fixing anchor bolt 4 from being corroded and rusted to cause damage and falling off.
Further, the joint between the adjacent XPS gypsum boards 3 is repaired and leveled with the anti-crack mortar 5 through a hanging net; wherein the net hanging and the anti-crack mortar 5 can not only shield the gap between the XPS gypsum board 3 from external water such as rainwater, but also prevent the crack of the anti-crack mortar 5 in the process of expansion with heat and contraction with cold of the XPS gypsum board 3 by coating the anti-crack mortar 5 on the net hanging.
When there is a temperature difference between the indoor and outdoor, the indoor temperature is easily transferred to the outdoor through the thermal bridge (concrete wall), so that it is difficult to maintain a comfortable temperature in the indoor. After the XPS gypsum board is installed, the heat transfer performance of the XPS gypsum board is low, the XPS gypsum board can greatly obstruct the indoor and outdoor temperature transfer, so that the indoor temperature can be kept comfortable for a long time, and a good heat preservation effect is achieved. And the surface gypsum board has better appearance and higher strength, does not influence secondary decoration, and can be directly handed over to owners.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art.
