Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building thermal insulation, and in particular to a thermal insulation structure integrated external hanging plate for building external walls and a mounting method. BACKGROUND

[0002] Building external wall thermal insulation is a technology for reducing energy loss by attaching an external hanging plate with a thermal insulation structure to the building main structure floor. The external hanging plate sets the thermal insulation layer between the inner leaf and the outer leaf, and is directly pasted or fixed on the wall surface. With the widespread application of green construction technology in the construction industry, the existing external hanging plate is generally prefabricated in the factory, then a plurality of external wall thermal insulation plates are transported to the construction site by loading and unloading vehicles, and then they are hoisted to the outside of the building main structure floor by hoisting devices for assembly.

[0003] The existing external hanging plate has an inner leaf, a thermal insulation layer and an outer leaf, and the inner leaf, the thermal insulation layer and the outer leaf are bonded by glue, that is, the existing glue layer needs to be set between the inner leaf and the thermal insulation layer, and between the thermal insulation layer and the outer leaf. Setting two layers of glue layers increases the thickness of the external hanging plate. Therefore, the existing prefabricated external hanging plate further adds a process of pressing the inner leaf, the glue layer, the thermal insulation layer, the glue layer and the outer leaf, that is, the production cost of the external hanging plate is increased. In addition, due to the limitation of the pressing process, the setting of the double-layer glue layer also greatly increases the thickness of the external hanging plate. Therefore, there are certain requirements for the setting of the thermal insulation layer, that is, if the thermal insulation layer is too thick, the bonding effect will be poor and the subsequent product maintenance efficiency will be low, but if the thermal insulation layer is too thin, the overall thermal insulation effect will be affected. Therefore, the thickness and material of the inner and outer leaves must be increased to further cooperate with the thermal insulation layer to achieve the thermal insulation effect of the external thermal insulation wall, which in turn leads to an excessively heavy overall external hanging plate and a complex and laborious installation process. SUMMARY

[0004] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present application provides a thermal insulation structure integrated external hanging plate for building external walls and a mounting method, which solves the technical problems that the existing prefabricated external hanging plate further adds a process of pressing the inner leaf, the glue layer, the thermal insulation layer, the glue layer and the outer leaf, that is, the production cost of the external hanging plate is increased, and the thickness of the inner and outer leaves is too large, which in turn leads to an excessively heavy overall external hanging plate and a complex and laborious installation process.

[0020] Referring to Figure 1 the drawings, the present application provides a thermal insulation structure integrated external hanging plate for building outer wall, which comprises an inner leaf 1, an outer leaf 2 and a positioning structure 3. The inner leaf 1 and the outer leaf 2 are arranged at intervals, and the gap between the inner leaf 1 and the outer leaf 2 is adjustable. Specifically, the gap between the two is used to fill the polyurethane, that is, the gap is the thickness of the polyurethane, and the thickness of the polyurethane can be adjusted according to the thermal insulation design requirements. The positioning structure 3 is used to block the four around the inner leaf 1 and the outer leaf 2 to form a glue injection cavity with an open top, and the polyurethane is injected into the glue injection cavity to form a polyurethane layer 4. The polyurethane layer 4 is used to bond the inner leaf 1 and the outer leaf 2 together, so that the inner leaf 1, the polyurethane layer 4 and the outer leaf 2 form an integrated external hanging plate.

[0022] And the process of the application is completely changed, that is, the application is completed in the factory, and the gap between the inner leaf plate 1 and the outer leaf plate 2 is adjustable, that is, when the thickness of the heat preservation layer is needed, the gap between the inner and outer leaf plates is adjusted and then filled with polyurethane. Compared with the traditional process, the double-layer adhesive material and the high-pressure pressing process are saved. Due to the increase of the overall strength, the thickness and weight of the overall outer hanging plate are reduced, so that the installation is convenient, and the integrated outer hanging plate structure and process are simplified, which greatly reduces the production and installation cost of the outer hanging plate.

The second side wall 102 of the inner leaf plate 1 is provided with an inner decorative layer 5, and one side of the inner decorative layer 5 is bonded with the second side wall 102 of the inner leaf plate 1. The inner leaf plate 1 and the inner decorative plate form an inner leaf plate assembly.

[0027] Further, the inner leaf plate 1 is a reinforced inorganic material plate, such as concrete or aerated sand plate.

[0028] Further, the vertical height of the outer leaf plate 2 and the polyurethane layer 4 is equal, and the vertical height of the polyurethane layer 4 is greater than the vertical height of the inner leaf plate assembly. The purpose of the height difference is to form a gap, thereby better matching the building main floor 100 for installation.

[0029] Further, the glue injection cavity is provided with a reinforcing pipe 7. The built-in reinforcing pipe 7 can be used as a cable pipe.

[0030] Further, the inner page plate 1 is provided with a steel mesh 8. Further, the inner page plate 1 is provided with multiple reinforcing bars, which is safer.
