Description

Technical Field

[0001] The utility model relates to the technical field of external wall thermal insulation, in particular to a metal surface sandwich panel point hanging external wall system. Background Art

[0002] Traditional exterior wall insulation often uses an integrated insulation and decoration panel system and a thin plaster system that fixes the exterior wall insulation panel by bonding and anchoring. There is also a dry-hanging curtain wall method in which a keel is installed on the wall, the finishing layer is installed on the keel, and the insulation layer is glued behind the finishing layer or on the wall. The existing installation system of the metal-faced sandwich panel also requires a keel anchored on the base wall to be preset between the base wall and the metal-faced sandwich panel.

[0003] For example, in the patent document with patent authorization announcement number CN106592790B, an external wall insulation system is disclosed, which mainly relies on bonding to fix the insulation board during installation. At the same time, it is also necessary to bond the back of the insulation integrated board or the thin plaster insulation board with no less than 50%-60% bonding mortar, and auxiliary anchoring components; in addition, during the curtain wall installation construction and metal-faced sandwich panel installation construction, it is also necessary to install corresponding metal keels on the wall.

[0004] From the above, it can be seen that when constructing this connection method in the prior art, it is not only necessary to install it through multi-point anchoring of steel supports and the base wall, but also to install horizontal and vertical keels, which leads to high overall construction costs and greater construction difficulty.

[0005] To this end, the utility model optimizes and improves the problems existing in the connection and installation construction of thermal insulation decorative integrated panels, curtain walls, and metal-surface sandwich panels with exterior walls in the prior art, and hereby proposes a metal-surface sandwich panel point-hanging exterior wall system to better reduce installation costs, improve construction efficiency, and better solve the problems existing in the prior art.

[0039] The following is a detailed description of the embodiments of the technical solution of the utility model in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the scope of protection of the utility model. Figure 1-Figure 11 as shown in .

[0040] Embodiment 1: A metal-faced sandwich panel point-hanging exterior wall system comprises a plurality of metal-faced sandwich panels 2 arranged on a base wall 1, each of the metal-faced sandwich panels 2 being fixed to the base wall 1 by a corresponding anchor, a sealing strip 4 being arranged between the plate seam position of each metal-faced sandwich panel 2 and the base wall 1, the sealing strip 4 enclosing the gap cavity between the inner side of the corresponding metal-faced sandwich panel 2 and the base wall 1 into a sealed cavity 5.

[0046] In any of the above schemes, it is preferred that the lengths of the steel supports 9 are different; and the steel supports 9 are in a "Z" shape, a "J" shape, a "C" shape or a "I" shape.

[0047] Embodiment 2: A metal-faced sandwich panel point-hanging exterior wall system comprises a plurality of metal-faced sandwich panels 2 arranged on a base wall 1, each of the metal-faced sandwich panels 2 being fixed to the base wall 1 by a corresponding anchor, the inner surface of each of the metal-faced sandwich panels 2 being abutted against the surface of the base wall 1 or the leveling layer of the surface of the base wall 1, each of the anchors being installed in a corresponding groove of the base wall 1 or a corresponding groove 12 of the leveling layer 11, and the outer end thereof extending into the corresponding interior of the metal-faced sandwich panel 2 to achieve anchoring.

[0048] The anchor (steel support 9) is hidden in the groove, and then the metal surface sandwich panel 2 is installed close to the base wall 1 or the leveling layer without a gap cavity. This can be applied to the situation where the base wall 1 is relatively flat and no other leveling measures are required.

[0049] In any of the above solutions, it is preferred that rock wool strips are installed at the tongue and groove 7 of each of the metal-faced sandwich panels 2 to achieve a combination of structural sealing and material sealing at the tongue and groove 7 .

[0050] In any of the above schemes, it is preferred that the flat opening 6 of each of the metal-faced sandwich panels 2 is filled with rock wool strips and the metal cover plate 8 is buckled outside with sealing tape to achieve panel sealing.

[0051] This structure can ensure the continuity of the insulation material at the board seams.

[0052] In any of the above schemes, it is preferred that the anchor member includes a steel support member 9, and the inner end through hole of the steel support member 9 is fixed to the base wall 1 by an installed expansion bolt 10, and the outer end of the steel support member 9 is fixed to the metal sandwich panel 2 on 9 by an installed self-tapping screw 3, and the outer end of the steel support member 9 is pressed against the metal surface sandwich panel 2 at the current position.

[0053] In any of the above schemes, it is preferred that the lengths of the steel supports 9 are different; and the steel supports 9 are in a "Z" shape, a "J" shape, a "C" shape or a "I" shape.

[0054] In any of the above schemes, it is preferred that the width of the sealing strip 4 is greater than the width of the plate seam at the current position, the thickness of the sealing strip 4 is the same as the thickness of the corresponding steel support 9, and the sealing strip 4 is pressed against the base wall 1 through the steel support 9.

[0055] The structural design of the sealing strip 4 in conjunction with the steel support 9 is applicable to the situation where the base wall 1 is uneven, and the steel support 9 and the sealing strip 4 can be used to partially level the base wall 1.

[0056] In any of the above solutions, it is preferred that the sealing strip 4 is made of rock wool strip or glass wool strip, or other materials with heat insulation and moisture-proof functions in the prior art.

[0057] This solution is different from the installation methods of traditional integrated panels and curtain walls. The curtain wall uses a keel and an anchoring component to fix the panel to the base wall 1, and the thermal insulation decorative integrated panel uses a combination of adhesive and anchoring to fix the integrated panel to the base wall 1. In this system, steel support members 9 are used to fix the metal-faced sandwich panel 2 to the base wall 1. There is no need to install a keel or use bonding to fix it. Only steel support members 9 are used to fix the metal-faced sandwich panel 2 to the base wall 1 through expansion bolts 10 and self-tapping bolts to form a closed gap cavity structure. Compared with the curtain wall system, the cost of the keel is saved, and compared with the thermal insulation decorative integrated panel, the bonding process and cost of the bonding mortar are eliminated.

[0058] In addition, during the specific construction process, the construction plan is selected according to the actual situation of the current base wall 1: for walls with good flatness, the steel support 9 is installed by local grooving; for walls with certain difficulties in leveling, one end of the steel support 9 is fixed to the base wall 1 with an expansion bolt 10, and the other end is used to press the sealing strip 4 onto the base wall 1.

[0059] Then, the metal face sandwich panel 2 is fixed to the steel support 9 by self-tapping bolts; the vertical seam (tongue and groove 7) is waterproofly sealed by using the tongue and groove 7 structure, and the transverse seam (flat seam 6) is sealed by using the metal cover plate 8 plus sealant.

[0060] From the inside to the outside, the system is composed of a base wall 1, a wall surface layer 11 (this surface layer may be absent depending on the wall), anchors 9, sealing strips 4, and metal-faced sandwich panels 2. During installation, holes are first punched on the base wall 1 according to the designed position to install the anchor components 9, and then the sealing strips 4 are pasted on the board seams after installation. The metal-faced sandwich panels 2 are installed. The horizontal seams are sealed with sealant, and the vertical seams are sealed with a tongue-and-groove 7 structure without sealing, and waterproofing is performed through the structure.

[0061] By fixing the metal-faced sandwich panel 2 on the base wall 1 through the above implementation scheme, the safety requirements are met while saving the material cost and labor cost of the installation.

[0062] In any of the above schemes, it is preferred that the plate structure adopted by the metal-faced sandwich panel includes but is not limited to a double-sided tongue-and-groove metal-faced sandwich panel, a four-sided tongue-and-groove metal-faced sandwich panel, a first box-shaped metal-faced sandwich panel, and a second box-shaped metal-faced sandwich panel.

[0064] In any of the above schemes, it is preferred that Figure 6 , Figure 7 As shown in the plate type and connection interface node structure of the four-sided tongue and groove metal face sandwich panel, the four-sided tongue and groove metal face sandwich panel is a metal face sandwich panel with tongue and groove on all four sides, and a core material 15 is arranged between the inner metal plate 14 and the outer metal plate 13 of the metal face sandwich panel.

[0065] In any of the above schemes, it is preferred that Figure 8 , Fig. 9As shown in the figure, the first box-shaped metal surface sandwich panel has a rectangular cross-sectional profile, a core material 15 is arranged between the inner metal plate 14 and the outer metal plate 13 of the metal surface sandwich panel, and the outer metal plate 14 is flush with both sides of the inner metal plate 13.

[0066] In any of the above schemes, it is preferred that Fig.10 , Fig.11 As shown in the plate type and connection interface node structure of the second box-shaped metal surface sandwich panel, the second box-shaped metal surface sandwich panel has a rectangular cross-sectional profile, a core material 15 is arranged between the inner metal plate 14 and the outer metal plate 13 of the metal surface sandwich panel, and the metal surface sandwich panel is protruding outward on both sides of the inner metal plate 14.

[0067] The above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above embodiments, or replace some or all of the technical features therein with equivalents.
