Description

Technical Field

[0001] The invention relates to the technical field related to exterior wall thermal insulation, and in particular to a fixed strip type exterior wall thermal insulation structure. Background Art

[0002] With the development of the global economy, the energy situation is severe, and building energy conservation has become a trend of development in the world today. External wall insulation is currently a strongly advocated insulation method.

[0003] In the existing soft-ceramic facing exterior wall insulation structure, the soft-ceramic material used as the decorative panel is only adhered to the insulation board by adhesive. However, in practice, if the quality of the adhesive is unreliable, or the adhesive is not applied according to the standard during construction, the soft-ceramic facing material will be in danger of falling off due to poor bonding. The falling soft ceramic may injure people, and the exterior wall of the building will also be affected by the falling soft ceramic.

[0004] Patent No. 2020111357484 discloses an anchored metal-covered exterior wall insulation structure with a decorative cover. Anchors are used to fix the metal decorative panels to the insulation layer. Although the anchors are used to fix the metal decorative panels to the exterior wall very firmly, the cover panels covered by the anchors are separated from each other and only serve a decorative effect. They do not have the function of fixing the decorative panels. In addition, there will be gaps and marks on the edges of the cover panels, which will affect the appearance if not handled properly. Summary of the invention

[0005] In order to overcome the defects of the prior art, a fixed strip type exterior wall external insulation structure is now provided to solve the problem that in the existing exterior wall external insulation structure, a cover sheet is used to cover the anchor nails to ensure beauty, but there will be marks on the edge of the cover sheet.

[0006] To achieve the above-mentioned purpose, a fixed-strip type exterior wall external insulation structure is provided, including a wall body, an insulation board is bonded to the outer side surface of the wall body, a decorative panel is bonded to the outer side surface of the insulation board, a fixing strip is installed on the upper part of the decorative panel, a plurality of anchor holes are opened on the fixing strip, and mounting holes corresponding to the anchor holes are provided at the portion where the fixing strip of the decorative panel is installed, an anchor nail is provided in the anchor hole, one end of the anchor nail passes through the anchor hole, the mounting hole and the insulation board in sequence and extends into the wall body, an expansion tube corresponding to the anchor nail is provided in the wall body, and the anchor nail is inserted in the expansion tube.

[0007] Furthermore, the fixing strip is in a straight line shape, and is provided with a groove matching the shape of the nail head of the anchor nail. The nail head of the anchor nail is covered with a cover plate, and sealant is filled between the nail head of the anchor nail and the cover plate, and the cover plate is fixed to the fixing strip by the sealant.

[0008] Furthermore, the decorative panel is a flat plate.

[0009] Furthermore, the decorative panel is a metal plate, and at least one of the four sides of the decorative panel is folded.

[0010] Furthermore, the insulation board and the decorative panel are bonded together to form an integrated insulation structure.

[0011] Furthermore, the nail head of the anchor nail is covered with a washer, the washer is adapted to the groove, and the depth of the groove is greater than the sum of the nail head height of the anchor nail plus the thickness of the washer plus the thickness of the cover plate.

[0012] Furthermore, the fixing strip has folded edges on both sides.

[0013] Furthermore, holes are opened at positions corresponding to the wall and the anchor nails, the expansion tube is inserted into the holes, the heads of the anchor nails are located in the grooves on the fixing strips, and the tails of the anchor nails are inserted into the expansion tube.

[0014] The beneficial effects of the present invention are:

[0015] First of all, decorative panels such as soft porcelain are not only bonded to the insulation board with adhesives, but also anchored to the exterior wall with anchors, so the decorative panels are fixed more reliably, greatly increasing the safety of exterior wall insulation structures such as soft porcelain.

[0016] Secondly, the fixing strip plays the function of fixing the decorative panel. The entire fixing strip is in contact with the decorative panel, so the contact area is large, the force effect of the decorative panel is good, and the fixing effect is also better.

[0017] Finally, the appearance of the fixing strip is basically the same as that of the existing exterior wall grouting strip, so the fixing strip can simulate the grouting strip. From a distance, the fixing strip will be seen as an ordinary grouting strip, so the anchor nails installed at the fixing strip will be very concealed and the exterior wall will be more beautiful.

[0025] The following describes the embodiments of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0026] Example 1

[0027] Reference Figures 1 to 5 As shown, the present invention provides a fixed-strip type exterior wall external insulation structure, including a wall 1, an insulation board 2 is bonded to the outer side surface of the wall 1, a decorative panel 3 is bonded to the outer side surface of the insulation board 2, a fixing strip 4 is installed on the decorative panel 3, a plurality of anchor holes are opened on the fixing strip 4, a mounting hole corresponding to the anchor hole is provided at the portion where the fixing strip 4 is installed on the decorative panel 3, an anchor nail 5 is provided in the anchor hole, one end of the anchor nail 5 passes through the anchor hole, the mounting hole and the insulation board 2 in sequence and extends into the wall 1, an expansion tube 6 corresponding to the anchor nail 5 is provided in the wall 1 and the insulation board 2, and the anchor nail 5 is inserted in the expansion tube 6.

[0028] In this embodiment, the fixing strip 4 is in a straight line shape, and a groove matching the shape of the nail head of the anchor nail 5 is provided on the fixing strip 4. The nail head of the anchor nail 5 is covered with a cover plate 7, and sealant is filled between the nail head of the anchor nail 5 and the cover plate 7, and the cover plate 7 is fixed to the fixing strip 4 by the sealant.

[0029] In this embodiment, the decorative panel 3 is a metal plate, and at least one of the four sides of the decorative panel 3 is folded, which can improve the hardness of the four sides of the decorative panel 3. The folded edge of the decorative panel 3 can be installed in the slot opened on the insulation board 2, or a U-shaped groove can be installed on the insulation board, and then the folded edge of the decorative panel 3 is installed in the U-shaped groove. If the folded edge is very small, it can be directly bonded to the insulation board. Of course, the decorative panel 3 can also be folded on one side, two sides, or three sides according to actual needs or customer requirements.

[0030] In this embodiment, the nail head of the anchor nail 5 is covered with a washer 8, the washer 8 is adapted to the groove, and the depth of the groove is greater than the sum of the nail head height of the anchor nail 5 plus the thickness of the washer 8 plus the thickness of the cover sheet 7.

[0031] As a preferred implementation, by providing a groove and a cover sheet 7, the anchor nail 5 is installed in the groove, and then the cover sheet 7 is used for covering, thereby ensuring both the fixing effect of the decorative panel 3 and the aesthetics of the decoration.

[0032] In this embodiment, the thermal insulation board 2 and the decorative panel 3 are separated.

[0033] During construction, according to the external wall insulation construction standard, the insulation board 2 is first bonded and fixed to the wall 1, and then the decorative panel 3 is bonded to the outside of the insulation board 2. Then, the decorative panel 3 is marked according to the position of the hole on the fixing strip 4, and then a hole is opened at the marked position with an electric tool, and the hole passes through the decorative panel 3, the insulation board 2 and the wall 1. Then, the expansion tube 6 is inserted into the hole, and then the fixing strip 4 is pressed on the decorative panel 3, and then the gasket 8 is placed at the hole position, and the anchor nail 5 is screwed into the expansion tube 6, and the cover sheet 7 is bonded to the groove on the fixing strip 4 at the head of the anchor nail 5 with a sealant.

[0034] The cover sheet 7 is the same color as the fixing strip 4. Since the cover sheet 7 is the same color as the fixing strip 4, the anchoring nails 5 are completely concealed, and the decorative surface is seamlessly integrated when viewed from a distance, thus achieving the aesthetic function.

[0035] The fixing strip 4 can be used in the middle of the decorative panel 3 or in the edge joint of each decorative panel 3. Of course, the edge joint of each decorative panel 3 can also be grouted, and the color of the grouting agent and the color of the fixing strip should be as consistent as possible during the grouting.

[0036] Example 2

[0037] Example 2 is basically the same as Example 1. Figure 1 and Figure 6 The present invention provides a fixed strip type exterior wall external insulation structure, including a wall 1, an insulation board 2 is bonded to the outer side of the wall 1, a decorative panel 3 is bonded to the outer side of the insulation board 2, a fixing strip 4 is installed on the decorative panel 3, a plurality of anchor holes are opened on the fixing strip 4, a mounting hole corresponding to the anchor hole is provided at the portion where the fixing strip 4 is installed on the decorative panel 3, an anchor nail 5 is provided in the anchor hole, one end of the anchor nail 5 passes through the anchor hole, the mounting hole and the insulation board 2 in sequence and extends into the wall 1, an expansion tube 6 corresponding to the anchor nail 5 is provided in the wall 1 and the insulation board 2, and the anchor nail 5 is inserted in the expansion tube 6.

[0038] In this embodiment, the decorative panel 3 can also be a flat decorative panel made of other materials such as a flat soft porcelain decorative panel or an orange peel aluminum plate.

[0039] In this embodiment, the fixing strip 4 has folded edges on both sides. In this structure, there are no openings at the folded edges, which can ensure that the fixing strip has better mechanical properties and can be produced with thin metal sheets, resulting in lower cost of the fixing strip.

[0040] In this embodiment, the insulation board 2 and the decorative panel 3 are bonded together in the factory to form an integrated insulation structure. During on-site installation, it is only necessary to install the integrated insulation structure on the wall 1, which saves one process during on-site installation and improves the construction efficiency of external wall insulation.

[0041] During construction, according to the external wall insulation construction standard, the integrated insulation board 2 and the decorative panel 3 are first bonded and fixed to the wall 1. Then, mark the decorative panel 3 according to the position of the hole on the fixing strip 4, and then use an electric tool to drill a hole at the marked position, and the hole passes through the decorative panel 3, the insulation board 2 and the wall 1. Then insert the expansion tube 6 into the hole, and then press the fixing strip 4 on the decorative panel 3, and then screw the anchor nail 5 into the expansion tube 6 at the hole position. The anchor nail 5 is selected to be the same color as the fixing strip 5. For example, the grouting is usually black, so the fixing strip 4 is black, and the anchor nail 5 is also black. In this way, even if the cover sheet 7 is not used, the anchor nail is not easy to see, and then apply black sealant to seal it.

[0042] In actual applications, the hole spacing of the holes on the decorative panel 3 and the hole spacing of the holes on the fixing strip 4 can adopt the same value for standardized production.

[0043] In practical applications, for leveling, mesh plastering is applied on the insulation board, which also belongs to the insulation board referred to in the present invention and is included in the patent of the present invention.

[0044] In actual applications, the solutions of Embodiment 1 and Embodiment 2 can be combined according to the choice of Party A.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
