Description

Technical Field

[0001] The present application relates to the field of building construction, and in particular to a construction process for exterior wall thermal insulation and decoration. Background Art

[0002] Currently, many technical measures are being adopted on the exterior walls of buildings to achieve thermal insulation and energy conservation. Among them, thermal insulation decorative panels are particularly widely used. They not only achieve the purpose of thermal insulation, but also eliminate the need for additional exterior decoration after the thermal insulation decorative panels are assembled with the exterior wall, greatly simplifying the installation process.

[0003] Related art discloses a process for exterior wall insulation and decoration. When installing the insulation decorative panels, adhesive mortar is first applied to the back of the panels. The panels are then manually pressed against the wall and kneaded to maintain a flat surface. Anchors are then installed on the side walls of the panels, securing them to the exterior wall using adhesive anchors. The joints are then filled with caulking strips and then tacked with weatherproof sealant.

[0004] Regarding the above-mentioned related technologies, the inventor believes that since the position of the thermal insulation decorative panels on the wall is installed and aligned with the assistance of the construction workers' experience, there is a problem of the thermal insulation decorative panels tilting on the wall, which can easily lead to the spacing between adjacent thermal insulation decorative panels increasing or decreasing, and it is subsequently difficult to install the caulking strips in the gaps between adjacent thermal insulation decorative panels. Summary of the Invention

[0005] In order to facilitate the installation of caulking strips in the gaps between adjacent thermal insulation decorative panels, the present application provides an exterior wall thermal insulation decorative finishing construction process.

[0006] The present application provides an exterior wall insulation and decoration construction process that adopts the following technical solutions:

[0007] A construction process for exterior wall thermal insulation and decoration, comprising the following steps:

[0008] The thermal insulation decorative panels are attached by applying bonding mortar on the back side of the thermal insulation decorative panels, and then using an auxiliary installation device to attach the thermal insulation decorative panels to the exterior wall surface; the auxiliary installation device includes a first positioning bar and a second positioning bar connected to the first positioning bar; the first positioning bar and the second positioning bar are arranged perpendicular to each other; a rotating rod is rotatably connected to the surface of the first positioning bar or the second positioning bar away from the exterior wall, and a leveling block is provided on the side wall of the rotating rod; the thermal insulation decorative panels abut against the leveling block;

[0009] Install anchors on the side walls of the insulation decorative panels according to the construction drawings, fasten the anchors to the exterior wall with bolts, and then remove the auxiliary installation device from the gap between adjacent insulation decorative panels;

[0010] The board seams are sealed by embedding the caulking strips into the gaps between adjacent insulation decorative panels, and then using weather-resistant sealant to fill the seams.

[0011] By adopting the above technical solution, when affixing the thermal insulation decorative panels to the exterior wall, the construction worker first adheres the first thermal insulation decorative panel to the exterior wall and determines the horizontal and vertical alignment of the thermal insulation decorative panel. The worker then uses the auxiliary installation device to place the corners of the first thermal insulation decorative panel against the side walls of the first and second positioning strips, and determines the horizontal and vertical alignment of the auxiliary installation device on the exterior wall. The corners of the subsequently installed thermal insulation decorative panels are then placed against the side walls of the first and second positioning strips, ensuring that adjacent thermal insulation decorative panels are symmetrical about the first or second positioning strip. This allows multiple thermal insulation decorative panels to be installed successively on the exterior wall. Taking the first insulation decorative panel installed on the exterior wall as the benchmark, the subsequently installed insulation decorative panels do not need to determine the horizontal and vertical positions, thereby improving the installation efficiency of multiple insulation decorative panels installed on the exterior wall. At the same time, after multiple insulation decorative panels are installed on the exterior wall, rotate the leveling block. If the leveling block encounters an obstacle during the rotation process, it means that there is a height difference between adjacent insulation decorative panels on the exterior wall. Use a rubber hammer to hammer the insulation decorative panels to flatten the bonding mortar on the back of the insulation decorative panels, so that the adjacent insulation decorative blocks are coplanar, and the position of the adjacent insulation decorative panels on the exterior wall can be determined. By introducing the first positioning strip and the second positioning strip, the problem of unequal spacing between adjacent insulation decorative panels is improved. At the same time, the practice of removing the auxiliary installation device after the anchor is installed makes it easier for construction workers to observe the inclination of the insulation decorative panels when installing the anchor, so as to adjust the horizontal and vertical directions of the insulation decorative panels in time, reduce the risk of tilting after multiple insulation decorative panels are fixed to the wall, and reduce the risk of unequal spacing between multiple insulation decorative panels, thereby facilitating the installation of caulking strips in the gaps between adjacent insulation decorative panels.

[0012] Optionally, it also includes determining the installation position of the auxiliary installation device, using an ink fountain to draw grid lines on the wall of the exterior wall, and aligning the edges of the first positioning strip and the second positioning strip with the grid lines of the exterior wall to determine the horizontal and vertical position of the auxiliary installation device.

[0013] By adopting the above technical solution and introducing grid lines, construction workers can quickly find the location where the auxiliary installation device is installed on the wall, and can timely observe the tilt state of the auxiliary installation device during the installation of the insulation panel on the wall, so that the tilt state of the clothing installation device can be corrected in time, and the problem of unequal spacing between adjacent insulation decorative panels after multiple insulation decorative panels are installed on the wall can be improved.

[0014] Optionally, the first positioning strip or the second positioning strip is bolted to the wall surface of the exterior wall.

[0015] By adopting the above technical solution, after the first insulation decorative panel is installed on the wall, and the side walls of the first and second positioning strips are both against the corners of the insulation decorative panel, the construction worker can bolt the first or second positioning strip to the wall of the exterior wall to fix the auxiliary installation device in place on the wall. This makes it easier for the construction worker to rotate the leveling block, freeing up the construction worker's hands to support the auxiliary installation device. At the same time, when the auxiliary installation device is removed from the exterior wall, a threaded hole will be left on the exterior wall. When the weather-resistant sealant is subsequently used to point the joints, some of the weather-resistant sealant will flow into the threaded hole, and some of the weather-resistant sealant will solidify in the threaded hole, thereby reducing the risk of the weather-resistant sealant falling off after a period of use.

[0016] Optionally, a telescopic rod is provided on the side wall of the rotating rod; the axes of the rotating rod and the telescopic rod are arranged perpendicular to each other; and there are multiple leveling blocks, which are arranged on the circumferential side of the telescopic rod along the axial direction of the telescopic rod.

[0017] By adopting the above technical solution and introducing the telescopic rod, the contact position between the leveling block and the thermal insulation decorative panel can be adjusted, so that the leveling block can adapt to thermal insulation decorative blocks of different sizes. At the same time, when the leveling block is rotated, the rotating area of the leveling block covers most of the surface of the thermal insulation decorative panel, achieving the effect of squeezing the thermal insulation decorative panel to make the panel surface level, thereby reducing the steps of hammering the thermal insulation decorative panel with a rubber hammer.

[0018] Optionally, a sliding hole is provided on the circumferential side of the rotating rod for the end of the telescopic rod to extend into; the sliding hole is extended along the axial direction of the rotating rod; the end of the rotating rod away from the first positioning bar is threadedly connected to an adjusting rod; the end of the adjusting rod extending into the sliding hole is rotatably connected to the side wall of the telescopic rod.

[0019] By adopting the above technical solution, the adjusting rod is rotated so that the end of the telescopic rod extending into the sliding hole slides along the axial direction of the rotating rod, thereby achieving an adjustable distance between the telescopic rod and the exterior wall surface, thereby achieving an effect that the leveling block can adapt to insulation decorative blocks of different thicknesses.

[0020] Optionally, the leveling block is elastic; and a surface of the leveling block facing the thermal insulation decorative panel is provided with an arc transition.

[0021] By adopting the above technical solution, when the telescopic rod drives the leveling block to make a circular motion, the arc transition of the leveling block guides it, thereby reducing the risk of adjacent insulation decorative panels with height differences hindering the circular motion of the leveling block. At the same time, the elasticity of the leveling block forces the insulation decorative panel to be squeezed toward the exterior wall, thereby achieving the effect of squeezing the insulation decorative panel to make the panel surface level, and reducing the step of hammering the insulation decorative panel with a rubber hammer.

[0022] Optionally, a limiting member is provided on the circumference of the telescopic rod; the limiting member is used to fix the telescopic length of the telescopic rod.

[0023] By adopting the above technical solution, the labor intensity of construction workers who need to fix the length of the telescopic rod by hand is reduced, thereby reducing the labor intensity of construction workers who need to install multiple thermal insulation decorative panels on the exterior wall.

[0024] Optionally, the side walls of the first positioning strip and the second positioning strip are rotatably connected to rollers; the circumference of the rollers is for the side walls of the thermal insulation decorative panel to abut.

[0025] By adopting the above technical solution, after the anchor fixes the thermal insulation decorative panel to the wall surface of the exterior wall, the construction workers will remove the auxiliary installation device from the wall surface of the exterior wall. The rotation of the roller facilitates the construction workers to remove the auxiliary installation device located between adjacent thermal insulation decorative panels, thereby reducing the labor intensity of the construction workers in removing the auxiliary installation device.

[0026] Optionally, the side walls of the first positioning strip and the second positioning strip are both provided with rotation grooves; the two ends of the rotating roller are respectively rotatably connected to the opposite inner walls of the rotation grooves; the bottom of the rotation groove is provided with an arc surface that fits the peripheral wall of the rotating roller.

[0027] By adopting the above technical solution, when squeezing the thermal insulation decorative block located on the exterior wall, part of the bonding mortar on the back of the thermal insulation decorative block will flow to the periphery of the roller. Through the setting of the arc surface at the bottom of the groove, during the rotation of the roller, the bonding mortar adhered to the periphery of the roller will scrape against the edge of the groove, so that the bonding mortar on the periphery of the roller will be retained on the surface of the first positioning strip and the second positioning strip, thereby achieving the self-cleaning effect of the roller.

[0028] Optionally, leveling bubbles are provided on the surfaces of the first positioning strip and the second positioning strip.

[0029] By adopting the above technical solution, construction workers can visually observe the horizontality and verticality of the auxiliary installation device, and promptly correct the horizontality and verticality of the insulation decorative panels on the exterior wall when multiple insulation decorative panels are installed on the exterior wall.

[0030] In summary, this application includes at least one of the following beneficial technical effects:

[0031] The introduction of the first positioning strip and the second positioning strip allows the spacing between adjacent insulation decorative panels to be fixed. At the same time, the practice of removing the auxiliary installation device after the anchor is installed makes it easier for construction workers to observe the inclination of the insulation decorative panels when installing the anchor, so as to adjust the horizontal and vertical positions of the insulation decorative panels in a timely manner, thereby reducing the risk of multiple insulation decorative panels tilting after being fixed to the wall and the risk of unequal spacing between multiple insulation decorative panels. This facilitates the installation of caulking strips in the gaps between adjacent insulation decorative panels, reduces the waste of trimming the caulking strips, and promotes green construction.

[0032] The auxiliary installation device is fixed to the wall by bolts, which makes it easier for construction workers to rotate the leveling block and frees their hands to support the auxiliary installation device. At the same time, when the auxiliary installation device is removed from the exterior wall, threaded holes will be left on the exterior wall. When weather-resistant sealant is used to point the joints, part of the weather-resistant sealant will flow into the threaded holes, and part of the weather-resistant sealant will solidify in the threaded holes, thereby reducing the risk of the weather-resistant sealant falling off after a period of use, extending the service life of the weather-resistant sealant, reducing the amount of weather-resistant sealant used, and being clean and environmentally friendly.

[0033] By rotating the adjusting rod, the end of the telescopic rod extending into the sliding hole slides along the axial direction of the rotating rod, thereby achieving an adjustable distance between the telescopic rod and the exterior wall surface, thereby achieving an effect in which the leveling block adapts to thermal insulation decorative blocks of different thicknesses.

[0039] The following is combined with Figure 1-4 This application is described in further detail.

[0040] An embodiment of the present application discloses an auxiliary installation device for assisting the installation of multiple thermal insulation decorative panels on an exterior wall, thereby improving the problem of unequal spacing between adjacent thermal insulation decorative panels after the multiple thermal insulation decorative panels are installed on the exterior wall.

[0041] Reference Figure 1 and Figure 2 An auxiliary installation device includes a first positioning bar 1 and a second positioning bar 2 connected to the first positioning bar 1 by mortise and tenon joints. The first positioning bar 1 and the second positioning bar 2 are arranged perpendicular to each other, and the surfaces of the first positioning bar 1 and the second positioning bar 2 are coplanar. The side walls of the first positioning bar 1 and the second positioning bar 2 that are away from each other are rotatably connected to rollers 3, and the circumference of the rollers 3 is provided for the side walls of the thermal insulation decorative panel to abut. The side walls of the first positioning bar 1 that are away from each other are provided with rotation grooves 4, and the side walls of the second positioning bar 2 that are away from each other are also provided with rotation grooves 4. The two ends of the roller 3 are rotatably connected to the opposite inner walls of the rotation groove 4, and the bottom of the rotation groove 4 is provided with an arc surface 41 that fits with the roller 3.

[0042] Reference Figure 1 One side of the first positioning strip 1 is used for abutting against the surface of the exterior wall, and the other side is provided with a rotating rod 5 and a leveling bubble 6. Similarly, one side of the second positioning strip 2 is also used for abutting against the surface of the exterior wall, and the other side is bonded and fixed with a leveling bubble 6. The significance of designing the leveling bubble 6 is that, since the first positioning strip 1 and the second positioning strip 2 are arranged perpendicular to each other, the leveling bubble 6 makes it easy for construction workers to observe the horizontal and vertical state of the auxiliary installation device after it is installed on the wall. After the intersecting side walls of the thermal insulation decorative panel abut against the rotating rollers 3 of the side walls of the first positioning strip 1 and the second positioning strip 2 respectively, the construction workers can intuitively know the horizontal and vertical state of the thermal insulation decorative panel on the wall.

[0043] Reference Figure 1 , the rotating rod 5 is rotatably connected to the intersection of the first positioning bar 1 and the second positioning bar 2. A telescopic rod 7 is provided on the side wall of the rotating rod 5, and the axes of the rotating rod 5 and the telescopic rod 7 are arranged perpendicular to each other. It should be noted that the telescopic rod 7 can be a two-section telescopic rod or a three-section telescopic rod. A sliding hole 51 is provided on the circumference of the rotating rod 5 for the end of the telescopic rod 7 to extend into, and the sliding hole 51 is extended along the axial direction of the rotating rod 5. The end of the rotating rod 5 away from the first positioning bar 1 is threadedly connected to the adjusting rod 8, and the end of the adjusting rod 8 extending into the sliding hole 51 is rotatably connected to the side wall of the telescopic rod 7. A limiting member 9 is provided on the circumference of the telescopic rod 7, and the limiting member 9 is used to fix the telescopic length of the telescopic rod 7. The limiting member 9 can be a bolt threadedly connected to the side of the telescopic rod 7, which can be turned forward and reversed to lock and unlock the telescopic rod 7. It can also be a rod inserted into the side of the telescopic rod 7. The side of the telescopic rod 7 is provided with multiple holes along its own length direction. The rods are inserted into different holes to achieve the effect of fixing the telescopic length of the telescopic rod 7. It can also be other limiting structures as long as it can fix the telescopic length of the telescopic rod 7.

[0044] Reference Figure 2 The telescopic rod 7 is bolted to a plurality of leveling blocks 10 on its circumferential side. The leveling blocks 10 are made of rubber and are arranged along the axial direction of the telescopic rod 7. As the telescopic rod 7 is extended or retracted, the spacing between the leveling blocks 10 also changes. The surface of the leveling block 10 away from the telescopic rod 7 is provided with an arc transition 101, which is provided for the thermal insulation decorative panel to abut against. When the leveling block 10 is rotated, the risk of adjacent thermal insulation decorative panels with height differences obstructing the circular motion of the leveling block 10 is reduced through the guidance of the arc transition 101 of the leveling block 10. At the same time, the elasticity of the leveling block 10 forces the thermal insulation decorative panel to be squeezed toward the exterior wall, thereby achieving the effect of squeezing the thermal insulation decorative panel to make the panel surface level, and reducing the step of hammering the thermal insulation decorative panel with a rubber hammer.

[0045] The embodiment of the present application also discloses an exterior wall insulation and decoration construction process implemented using the above-mentioned auxiliary installation device.

[0046] Reference Figures 1 to 4 , a construction process for exterior wall thermal insulation and decoration, comprising the following steps:

[0047] S1. Determine the installation position of the auxiliary installation device: a. Use an ink fountain to draw grid lines on the wall surface of the exterior wall.

[0048] b. Use an impact drill or electric hammer to drill holes in the base wall according to the layout of the grid lines.

[0049] c. Pre-install the adjustable bracket with anchors so that the adjustable bracket is on the horizontal reference line of the grid line.

[0050] d. Align the edges of the first positioning strip 1 and the second positioning strip 2 with the horizontal reference line and the vertical reference line of the grid line respectively, observe the position of the bubbles in the level bubble 6, and then use bolts to fix the first positioning strip 1 and the second positioning strip 2 to the exterior wall.

[0051] S2. Prepare the special bonding mortar: Prepare the mortar according to the specified ratio. Stir in a mortar mixer or in a portable plastic bucket with an electric stirrer for 3-5 minutes. Use the mixed special bonding mortar within 2 hours.

[0052] S3, pasting thermal insulation decorative panels: a. Use the point-sticking method to apply bonding mortar on the back of the thermal insulation decorative panels. The ratio of the area of the bonding mortar to the area of the thermal insulation decorative panels should meet the relevant regulations.

[0053] b. The thermal insulation decorative panels should be laid horizontally from bottom to top according to the predetermined layout position. The adjustable brackets should support more than 1 / 3 of the thickness of the thermal insulation decorative panels.

[0054] c. Place the corners of the insulation decorative panel against the rollers 3 on the side walls of the first and second positioning strips 1 and 2, then rotate the telescopic rod 7. The leveling block 10 squeezes the front of the insulation decorative panel, flattening the dotted adhesive mortar on the back of the panel. Next, push another insulation decorative panel with adhesive mortar applied to the back against the exterior wall, so that the intersecting side walls of the insulation decorative panel rest against the side walls of the rollers 3. Adjacent insulation decorative panels are symmetrical about the first positioning strip 1 or the second positioning strip 2. Using the first insulation decorative panel installed on the exterior wall as a reference, subsequent insulation decorative panels do not need to be leveled. Rotate the telescopic rod 7 to force the leveling block 10 to squeeze the surface of the insulation decorative panel, reducing the height difference between adjacent insulation decorative panels and improving the installation efficiency of multiple insulation decorative panels on the exterior wall.

[0055] S4. Install anchors. a. Install anchors on the side walls of the insulation decorative panels according to the construction drawings, and use bolts to lock the anchors to the exterior wall.

[0056] b. Use an electric screwdriver to loosen the bolts that secure the first positioning strip 1 and the second positioning strip 2 to the wall, and then remove the auxiliary installation device from the gap between adjacent insulation decorative panels.

[0057] S5, board seam sealing treatment, a. The board seam treatment of the thermal insulation decorative board should be carried out 24 hours after installation. Before gluing, the protective film of the thermal insulation decorative board at the glue seam should be torn off.

[0058] b. According to the construction requirements of the drawings, use qualified insulation caulking strips to fill the joints, and the caulking should be tight.

[0059] c. Stick paper tape on the front of the insulation decorative board to reduce the contamination of the front of the insulation decorative board by glue.

[0060] d. Use a glue gun to squeeze weather-resistant sealant into the gaps between adjacent insulation decorative panels and fill the joints with weather-resistant sealant. The color of the sealant should be as required by the special plan, and the filling should be full, dense, continuous, uniform, and free of bubbles.

[0061] S6, cleaning and removing protective film: After all processes are completed, tear off the protective film on the front of the thermal insulation decorative board. If sealant is accidentally left on the front of the thermal insulation decorative board, it should be promptly removed with a cloth dipped in a special detergent, and then cleaned again with a cloth with clean water.

[0062] The implementation principle of an exterior wall insulation and decoration construction process according to an embodiment of the present application is as follows: When attaching and fixing an insulation decorative panel to an exterior wall surface, a construction worker, using an auxiliary installation device, pushes the insulation decorative panel, coated with bonding mortar, onto the exterior wall surface, so that the intersecting sidewalls of the insulation decorative panel abut against the sides of rollers 3 on the sidewalls of first and second positioning strips 1 and 2, respectively, to determine the horizontal and vertical alignment of the insulation decorative panel. The worker then rotates a leveling block 10 to reduce the height difference between adjacent insulation decorative panels, flattening the bonding mortar on the back of the insulation decorative panel and aligning the adjacent insulation decorative panels. This completes the positioning of adjacent insulation decorative panels on the exterior wall surface. The auxiliary installation device is then removed from the exterior wall surface, leaving threaded holes in the exterior wall surface. When weather-resistant sealant is subsequently used for grouting, some of the weather-resistant sealant will flow into the threaded holes, while some will solidify within the holes, reducing the risk of the weather-resistant sealant detaching from the wall surface after a period of use.

[0063] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
