Description

Technical Field

[0001] The present application relates to the technical field of building construction, and in particular to an internal insulation structure of an exterior wall. Background Art

[0002] At present, the existing exterior wall insulation structure is mostly to embed the rock wool board directly in the keel cavity. Since the cross-sectional area of ​​the keel is large and it is not covered with rock wool board, a cold bridge phenomenon occurs at the keel, which increases the heat conduction between the inside and outside of the building, thereby increasing the air conditioning and heating load and energy consumption in the building. If the rock wool board is fixed directly with anchor bolts without using the keel, when the building is high, the loosening of the upper rock wool board will cause a certain amount of pressure on the lower rock wool board, resulting in the risk of sinking and falling off of the lower rock wool board. Utility Model Content

[0003] Based on this, it is necessary to provide an internal insulation structure of an exterior wall to solve the defects mentioned in the above background technology.

[0025] Example

[0026] This embodiment provides an exterior wall internal insulation structure, such as Figure 1 As shown, it includes a rock wool board layer 1, a bracket 2, an anchor bolt 3 and a protective layer. Compared with the traditional structure, the internal insulation structure of the exterior wall is firmly installed, does not fall or fall off, and has good thermal insulation effect.

[0027] The rock wool board layer 1 is fixed to the outside of the floor slab and the base wall by an adhesive 4. A leveling layer 5 is arranged between the adhesive 4 and the floor slab and the base wall to adjust the flatness of the fixed surface of the rock wool board layer 1, so that the overall structure is more neat and beautiful. The rock wool board layer 1 is divided into a plurality of plates from bottom to top with the floor slab of each layer as the dividing line. The bracket 2 is arranged between adjacent plates and fixed to the floor slab. Its upper and lower ends are tightly fitted with the adjacent plates to support the upper plate to prevent it from overlapping and adding to the lower plate, increasing the risk of the lower plate falling off.

[0028] In this embodiment, a single plate of each layer includes multiple rock wool boards, which are connected to the base wall through anchor bolts 3. Adjacent rock wool boards of the same plate are tightly fitted to avoid large gaps that reduce the thermal insulation effect.

[0029] In this embodiment, after the rock wool board is firmly bonded, the anchor bolts 3 should be installed within 8 to 24 hours, and the anchor bolts 3 should enter the concrete wall by no less than 25 mm and the masonry wall by no less than 50 mm. The number of anchor bolts 3 should be placed as required (centered horizontally and evenly spaced vertically). Any area larger than 0.1m 2 The single board must be fixed with no less than 10 pieces per square meter. The external corners, the edges of holes and the surroundings of windows must be tightened within 2m in the horizontal and vertical directions, with a spacing of no more than 250mm and 60mm from the edge of the base.

[0030] In this embodiment, the bracket 2 is a galvanized angle steel, and one side limb plate is provided with a through hole. It is fixed to the inner base wall of the outer wall at the elevation of the main structure floor by means of expansion bolts passing through the through holes. The galvanized angle steel is arranged along the horizontal length of the floor. When the first-floor bracket 2 encounters an opening, if there is no concrete cantilever support on the upper part of the opening, a bracket 2 is arranged. The above measures are taken for support and layered unloading, which is convenient for the pasting construction of the first row of rock wool boards, and effectively prevents the overall vertical deformation and excessive displacement of the rock wool boards, which may cause quality risks such as cracking of the plastering mortar.

[0031] After the bracket 2 is connected to the floor slab, a leveling layer 5 is constructed. The leveling layer 5 is arranged on the upper and lower sides of the bracket 2, and is flush with the outer side of the limb plate on the side where the bracket 2 is connected to the floor slab, so as to keep the surface of the rock wool board layer 1 flush. The adhesive 4 is fully applied to the inner side of the rock wool board 4 to make it firmly connected with the bracket 2 and the leveling layer 5.

[0032] In this embodiment, the fixed pressure connector 9 is T-shaped, and the adjacent rock wool boards are tightly attached. One end of the fixed pressure connector 9 is connected to the base wall through the gap between the adjacent rock wool boards, and inserts are provided on both sides of the other end. The inserts are respectively inserted into the adjacent rock wool boards to fix the rock wool boards.

[0033] The protective layer is arranged on the outside of the rock wool board layer 1, and includes a first plastering mortar and alkali-resistant mesh cloth layer 6, a second plastering mortar and mesh cloth layer 7 and a third plastering mortar layer 8 which are arranged in sequence from the indoor side to the outside.

[0034] In this embodiment, it also includes a foamed polyethylene strip, which is arranged in the gap between the rock wool board layer 1 and the ceiling. The intersections between the rock wool board layer 1, the ceiling and the foamed polyethylene strip need to be filled with building sealant twice, and the filling thickness is 50% to 70% of the gap width.

[0035] The utility model divides the rock wool board layer 1 into multiple plates from bottom to top with the floor as the dividing line, and each plate is independently supported by a bracket 2 connected to the floor, thereby reducing the pressure on the lower rock wool board, reducing the risk of sinking and falling of the rock wool board and the quality risk of cracking of the plastering mortar. At the same time, large keels are eliminated, cold bridges are reduced, and heat conduction inside and outside the building is reduced, thereby reducing the indoor air conditioning, heating load and energy consumption of the building.

[0036] The utility model arranges a fixed pressure connector 9 between adjacent rock wool boards in the same plate. When the anchor bolt 3 of a rock wool board fails, the fixed pressure connector 9 can fix the rock wool board. The dual fixing structure of the anchor bolt 3 and the fixed pressure connector 9 greatly improves the reliability of the fixation of the rock wool boards in the same plate.

[0037] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
