Description

Technical Field

[0001] The present invention relates to the field of building construction, and in particular to an integrated construction method for thermal insulation and decoration of building exterior walls. Background Art

[0002] At present, the walls of traditional structures are mostly brick-concrete or commercial concrete structures. Due to the nature of the materials, the freedom of space layout is limited. If the bay is too large, the slabs will be thick, the beams will be high, and the columns will be large, resulting in the phenomenon of "fat beams and fat columns". This not only affects the appearance, but also increases the deadweight and the cost. When buyers re-decorate, they often change the position of the walls on their own, which increases hidden dangers. Moreover, when using brick-concrete or commercial concrete structures as walls, the amount of on-site work is large, and the harm caused to the surrounding environment is also relatively large. Therefore, how to solve the above problems has become a long-standing technical problem that is difficult to solve. As a technological innovation, integrated exterior wall insulation decorative panels are gradually replacing the original exterior wall decoration.

[0003] In the prior art, exterior wall thermal insulation decorative integrated panels are mainly fixed to the exterior wall by a combination of bonding and anchoring, that is, while being bonded and fixed with an adhesive, anchors are also used for fixing. Specifically, the anchors are used to clamp the decorative panels of the thermal insulation decorative finished panels and fix the thermal insulation decorative finished panels to the wall. Under the condition of long-term wind, sun and corrosion, the bonding strength will be reduced, and the thermal insulation decorative panels are at risk of falling off. The use of anchors will punch holes in the original wall, thereby damaging the original wall. When the thermal insulation decorative finished panels are damaged and need to be replaced, the anchor points are disassembled and then the new finished panels are installed in the original position. If the new finished panels are fixed using the original anchor positions, the original opening positions will be looser than before due to the previous disassembly. Even if other materials are filled in the holes to increase friction, since the filling materials are made of different materials from the wall and are relatively independent of the wall and have no adhesion, the firmness of the newly installed finished panels is still not as good as before, and there is a risk of loosening and falling. Re-drilling holes will cause damage to the wall again. There is a need for a technology that can reduce damage to the wall when the integrated decorative panels are replaced later. Summary of the Invention

[0004] The present invention provides an integrated construction method for thermal insulation and decoration of building exterior walls, which can reduce damage to the wall when the integrated decorative panels are replaced at a later stage.

[0005] In order to solve the above technical problems, this application provides the following technical solutions:

[0006] A method for integrated construction of thermal insulation and decoration of building exterior walls, comprising the following steps:

[0007] S1: Casting a concrete outer wall; a plurality of first bolts for positioning are fixed at intervals on the concrete outer wall;

[0008] S2: Fabricate the thermal insulation and decoration integrated board according to the design requirements; the thermal insulation and decoration integrated board at least includes a thermal insulation layer and a decoration layer; installation wing plates are fixed on the peripheral side edges of the thermal insulation and decoration integrated board.

[0009] S3: Conduct basic treatment on the exterior wall, removing floating dust, dirt, protrusions, etc. on the exterior wall.

[0010] S4: The thermal insulation and decoration integrated board is installed and fixed on the exterior wall through the first bolts.

[0011] S5: Conduct caulking treatment on the gaps between two adjacent thermal insulation and decoration integrated boards.

[0012] The basic principle and beneficial effects of this solution: The first bolts are arranged at intervals on the concrete exterior wall with a constant interval distance, which is convenient for the later installation of the thermal insulation and decoration integrated board. After the concrete exterior wall is poured, the floating dust, dirt, and protrusions on the exterior wall are cleaned to ensure the flatness of the installation plane, making it easy to install the thermal insulation and decoration integrated board and preventing dislocation. After installing the thermal insulation and decoration integrated board, caulking treatment is carried out for the gaps, making the exterior wall of the building more beautiful and improving the visual effect.

[0013] This solution fixes the first bolts on the exterior wall as the anchor points for the later installation of the thermal insulation and decoration integrated board. Compared with the traditional method of drilling holes in the wall and then fixing with screws, it avoids the problems of the wall holes being reused or repeatedly drilled during replacement, resulting in insecure installation and wall damage. The later caulking treatment fills the gaps between adjacent thermal insulation and decoration integrated boards, reducing the probability of rainwater and dew invading and corroding the thermal insulation and decoration integrated board, and ensuring the service life of the thermal insulation and decoration integrated board.

[0014] Further, the construction steps of the concrete exterior wall in step S1 are as follows:

[0015] a: Drill bolt positioning holes at intervals according to the design dimensions on the concrete exterior wall formwork.

[0016] b: Build the steel bar framework of the concrete exterior wall.

[0017] c: Fix the concrete exterior wall formwork on both sides of the steel bar framework. After the rod body of the first bolt passes through the bolt positioning hole, it is fixed on the concrete exterior wall formwork with a nut; the bolt head of the first bolt and the steel bar framework are on the same side of the concrete exterior wall formwork; an embedded part is fixed on the bolt head.

[0018] d: Pour concrete in the area enclosed by the concrete exterior wall formwork.

[0019] e: After the concrete hardens and forms, remove the nut and the concrete exterior wall formwork in sequence, making the first bolt exposed.

[0020] Beneficial effects: When pouring concrete, through the erection of the concrete exterior wall formwork, the first bolt is embedded in the concrete through the embedded part, so that the first bolt forms an integral body with the concrete exterior wall, ensuring the bearing capacity of the first bolt. The exterior wall formwork plays a role in shaping the concrete and also restricts the position of the first bolt. After the concrete solidifies, the formwork is removed, and the first bolts are arranged evenly at intervals on the exterior wall for the subsequent installation of the integrated thermal insulation and decoration board.

[0021] Furthermore, it also includes an adjustment block. The adjustment block is fixedly connected to the first bolt. A number of corresponding mounting holes are provided on the adjustment block and the mounting wing plate. It also includes a second bolt, and the second bolt is used to fixedly connect the adjustment plate and the integrated thermal insulation and decoration board.

[0022] Beneficial effects: The first bolt may have a small displacement during the pouring process, resulting in difficulties in later installation. Through the setting of the adjustment block, the first bolt plays a supporting role. The adjustment block is directly fixed to the integrated thermal insulation and decoration board through the second bolt, solving the problem of difficult installation in the case of small displacement of the first bolt. At the same time, it can also reduce the installation density of the first bolt, saving construction time and reducing construction difficulty.

[0023] Furthermore, for the caulking treatment in step S5, a sealant is selected, and the sealing thickness is 0.5 - 1 mm.

[0024] Beneficial effects: While caulking, it isolates the internal corrosion of the integrated thermal insulation and decoration board from the external air and water.

[0025] Furthermore, the integrated thermal insulation and decoration board also includes an inner protective layer. The position where the inner protective layer fits with the exterior wall uses a flexible material. When installing the integrated thermal insulation and decoration board, mortar is applied on the exterior wall, and the mortar is used to bond the exterior wall and the integrated thermal insulation and decoration board.

[0026] Beneficial effects: The bonding and bolt fixation are carried out simultaneously, making the installation of the integrated thermal insulation and decoration board on the exterior wall more firm.

[0027] Furthermore, the integrated thermal insulation and decoration board is one of the glazed foamed ceramic thermal insulation board, metal integrated board, water-in-water integrated board, water-in-sand integrated board, real stone integrated board, thin porcelain board integrated board, and texture paint integrated board.

[0028] Beneficial effects: The glazed foamed ceramic thermal insulation board is one of the products of the exterior wall thermal insulation and decoration integrated system. It is a lightweight plate-shaped ceramic product with thermal insulation performance sintered and expanded at one time at 1200 °C. The decorative layer and the thermal insulation layer of this board are sintered at high temperature at one time, with rich decorative effects. It has the characteristics of low thermal conductivity, good decorative effect, simple construction and installation, high product cost performance, wide application fields, and the same lifespan as the building. The other integrated boards are all common integrated thermal insulation and decoration boards and are easy to obtain. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] An integrated construction method for building exterior wall thermal insulation and decoration includes the following steps:

[0046] S1: Pour the concrete exterior wall 2; A number of first bolts 1 for positioning are fixedly arranged at intervals on the surface of the concrete exterior wall 2; Among them, the construction steps of the concrete exterior wall 2 are: as shown in the appendix Figure 2 as follows

[0047] a: Drill bolt positioning holes at intervals on the concrete exterior wall 2 formwork according to the design dimensions;

[0049] c: As shown in the appendix Figures 3 - 7 Fix the concrete exterior wall 2 formwork on both sides of the steel bar framework. After the rod body of the first bolt 1 passes through the bolt positioning hole, it is fixed on the concrete exterior wall 2 formwork with a nut; The bolt head of the first bolt 1 and the steel bar framework are on the same side of the concrete exterior wall 2 formwork; A pre-embedded part 11 is fixed on the bolt head; An anchor bar 12 is connected to the pre-embedded part 11 and fixed on the pre-embedded part 11. After the concrete is poured, it is used to increase the contact area with the concrete, so that the pre-embedded part 11 is more firmly fixed in the concrete, thus ensuring the stability of the pre-embedded part 11 and the first bolt 1 is fixed on the concrete surface according to the design requirements, preparing for the later installation of the integrated thermal insulation and decoration board 5.

[0050] d: Pour concrete in the area surrounded by the concrete exterior wall 2 formwork;

[0051] e: After the concrete hardens and forms, remove the nut and the concrete exterior wall 2 formwork in sequence, so that the first bolt 1 is exposed.

[0052] S2: Manufacture the integrated thermal insulation and decoration board 5 according to the design requirements; The integrated thermal insulation and decoration board 5 is a glazed foamed ceramic thermal insulation board. The integrated thermal insulation and decoration board 5 at least includes a thermal insulation layer and a decoration layer; Installation wing plates 6 are fixedly arranged on the peripheral side edges of the integrated thermal insulation and decoration board 5; The integrated thermal insulation and decoration board 5 further includes an inner protective layer, and a flexible material is used at the position where the inner protective layer is attached to the outer wall surface. When installing the integrated thermal insulation and decoration board 5, mortar is smeared on the outer wall, and the mortar is used to bond the outer wall and the integrated thermal insulation and decoration board 5.

[0053] S3: Conduct basic treatment on the outer wall surface, removing floating dust, dirt, protrusions, etc. on the outer wall surface;

[0054] S4: As shown in the appendix Figures 8 - 9As shown, the integrated thermal insulation and decoration board 5 is fixedly installed on the exterior wall through the first bolt 1; an adjusting block 4 is further included, the adjusting block 4 is fixedly connected to the first bolt 1, a number of corresponding mounting holes are formed in the adjusting block 4 and the mounting wing plate 6, and a second bolt 7 is further included, the second bolt 7 is used to fixedly connect the adjusting plate and the integrated thermal insulation and decoration board 5. The opening in the middle of the adjusting block 4 is used for the first bolt 1 to pass through and the adjusting block 4 is fixed on the exterior wall through a nut. The second bolt 7 passes through the mounting holes reserved in the adjusting block 4 and the mounting wing plate 6 to complete the fixed installation of the integrated thermal insulation and decoration board 5.

[0055] S5: Caulking treatment is carried out on the gap between two adjacent integrated thermal insulation and decoration boards 5. The caulking treatment uses sealant, and the sealing thickness is 1 mm.

[0056] Embodiment 2

[0057] The difference between Embodiment 2 and Embodiment 1 is that: the thermal insulation layer is a liquid thermal insulation layer 61, a sealed cavity is formed inside the integrated thermal insulation and decoration board 5, and a liquid thermal insulation material is provided in the sealed cavity. In this solution, the liquid thermal insulation material is water. As shown in the appendix Figures 10 - 13 As shown, the mounting wing plate 6 is divided into two layers, namely a base (not marked with a serial number in the figure) and an upper cover 68. The base is fixedly connected to the integrated thermal insulation and decoration board 5, the upper cover 68 is slidably connected to the base, and the upper cover 68 and the base are provided with coaxially arranged mounting holes for the installation of the second bolt 7. A second spring 67 is fixedly arranged between the upper cover 68 and the base. The upper end and the lower end of the second spring 67 are respectively fixedly connected to the upper cover 68 and the base. As shown in the appendix Figure 12As shown in the figure, a channel communicating with the inner cavity of the mounting wing plate 6 is provided at a position of the integrated thermal insulation and decoration board 5 close to the mounting wing plate 6. The channel at one end close to the liquid thermal insulation layer 61 communicates with the liquid thermal insulation layer 61. The liquid pushing block 63 is slidably connected to the channel at one end close to the liquid thermal insulation layer 61. The liquid pushing block 63 is used to make the liquid thermal insulation layer 61 airtight relative to the channel. The channel is stepped. The cross-sectional area of the channel at one end close to the liquid thermal insulation layer 61 is larger than the cross-sectional area of the channel at the position close to the mounting wing plate 6. It also includes a first spring 64. The upper end of the first spring 64 is fixed to the liquid pushing block 63, and the lower end is fixed to the platform formed by the step of the channel. A steel cable 65 is provided between the upper cover 68 and the liquid pushing block 63. One end of the steel cable 65 is fixedly connected to the liquid pushing block 63, and the other end is fixedly connected to the upper cover 68. The steel cable 65 is coaxial with the first spring 64. A fixed pulley 66 is fixedly provided at the turning position of the steel cable 65. The fixed pulley 66 abuts against the steel cable 65. It also includes a caulking block 62. The caulking block 62 is slidably connected to the space forming the liquid thermal insulation layer 61. It also includes a third spring 69. One end of the third spring 69 is fixedly connected to one end of the caulking block 62 close to the liquid thermal insulation layer 61, and the other end is fixedly connected to the body of the integrated thermal insulation and decoration board 5. In this solution, two convex blocks are fixedly protruded in the liquid thermal insulation layer 61 (which is equivalent to protruding from the body of the integrated thermal insulation and decoration board 5). One end of the third spring 69 is fixed to the convex block, and the convex block is provided with holes for the liquid thermal insulation material to pass through. The caulking block 62 is of the same length as the side of the integrated thermal insulation and decoration board 5 with the mounting wing plate 6. The plane where the caulking block 62 is located is parallel to the plane where the mounting wing plate 6 is located. The second bolt 7 is sprayed with a fluorescent material after installation.

[0058] The specific implementation method is as follows. After the second bolt 7 passes through the mounting holes of the upper cover 68 and the lower cover and is fixed with a nut, after the fixing is completed, a fluorescent material is sprayed on the nut and the second bolt 7. During the process of tightening the nut, the upper cover 68 slides inside the base, the second spring 67 is compressed, the steel cable 65 displaces along the channel, the fixed pulley 66 changes the movement direction of the steel cable 65 to make it move upward, pushes the liquid pushing block 63 to move upward, the first spring 64 is in a stretched state at this time, the space of the liquid thermal insulation layer 61 above the liquid pushing block 63 decreases, the pressure applied to the caulking block 62 increases, and the caulking block 62 is pushed to move outward, as Figure 13As shown, the third spring 69 between the caulking block 62 and the bump is in a stretched state. When the nut locks the second bolt 7, the upper cover 68 just slides to the limit position relative to the base, and the caulking block 62 also just extends to the limit position. At this time, the liquid insulation layer 61 is still in a sealed state, the first spring 64 and the third spring 69 are in a stretched state, and the second spring 67 is in a compressed state. When the nut becomes loose, the second spring 67 will release the pressure and push the upper cover 68 outwards. When the nut is displaced, the cable 65 moves together with the locked upper cover 68, thereby driving the liquid pushing block 63 to return to its original position, and the caulking block 62 will also slide inwards. When the displacement of the nut is large enough, the nut and the second bolt 7 will be exposed to view. In the dark, when fluorescence is detected from the outside, it can be known that the nut has become loose, and repairs or replacements can be carried out in a timely manner. The caulking block 62 is made of a fixed plate, such as a PVC board.

[0059] This solution replaces the existing caulking process with the caulking block 62. While the insulation layer plays its own heat preservation role, it also has the function of promoting caulking, reducing the number of process steps and facilitating construction.
