Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a construction structure and method for an exterior wall insulation board waterproof and breathable membrane. Background Technology

[0002] When installing rock wool insulation for exterior walls, two methods are used: adhesive bonding and anchoring. After installation, a waterproof and breathable membrane needs to be laid on the surface. The conventional method involves covering the rock wool with a waterproof membrane after installation and then anchoring it with rock wool nails. This method can damage the waterproofing around the rock wool nails, posing a risk of leakage. Furthermore, because the waterproof and breathable membrane is made of plastic, conventional wall surfaces are difficult to fix to it using methods such as plastering mortar or concrete. Therefore, how to properly fix the waterproof and breathable membrane to the exterior wall surface without damaging it remains a challenge.

[0003] Currently, a common method for fixing exterior walls is to use a curtain wall structure. In the existing technology, such as the invention patent with patent number 202010633672.1, an aluminum panel curtain wall with a waterproof and heat-insulating structure at the sealing point and its manufacturing process are disclosed. The waterproof and heat-insulating structure includes a waterproof layer and a heat-insulating layer. The waterproof layer and the heat-insulating layer are bonded together with a waterproof adhesive emulsion. The vertical keel is fixed to the wall by screws passing through the waterproof and heat-insulating structure, and the connection between the screw and the waterproof and heat-insulating structure is sealed with a sealing glue seat.

[0004] In the aforementioned existing technologies, anchoring the curtain wall frame with screws still cannot avoid damaging the waterproof and breathable membrane, creating a risk of leakage. Moreover, screw anchoring can also damage the insulation layer. Due to inconsistent heat transfer efficiency at the screw points, thermal bridging occurs, affecting the wall's insulation capacity. More seriously, moisture in the air can condense into water at these points, causing frost and condensation. Long-term frost and condensation can lead to structural damage, such as steel corrosion, concrete cracking, and insulation layer rot. It also promotes the growth of mold and bacteria, affecting indoor air quality and health. Furthermore, the damaged waterproof and insulation layer has protective loopholes and is unable to resist the erosion of frost and condensation. In addition, the numerous anchoring points of the curtain wall structure exacerbate the adverse effects of thermal bridging, and the resulting damage cannot be ignored.

[0005] Therefore, it is necessary to study a construction structure and method for waterproof and breathable membranes for external wall insulation boards. Summary of the Invention

[0006] Therefore, the purpose of this invention is to provide a construction structure and method for a waterproof and breathable membrane for exterior wall insulation boards, which can effectively solve the problem that fixing the waterproof and breathable membrane and the surface layer in traditional exterior wall waterproof and insulation systems will damage the waterproof and insulation layers, resulting in water leakage and thermal bridging.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0008] An external wall insulation board waterproof and breathable membrane construction structure includes a wall, insulation board, waterproof and breathable membrane, pressure plate, window support frame, curtain wall frame and surface layer;

[0009] The wall has windows, and an insulation board is fixed on the outer surface of the wall to form an insulation layer. The insulation layer has multiple pressure grooves.

[0010] The waterproof and breathable membrane is adhered to the insulation layer, and the edges of the waterproof and breathable membrane are folded into the edges of the insulation layer, the window edges, and the groove to form a waterproof layer.

[0011] The curtain wall frame includes a fixed frame, a cantilever frame, and a surface layer frame. The fixed frame is fixed to the wall. The cantilever frame is fixed to the fixed frame at intervals and extends outward from the wall. The end of the cantilever frame is fixed to the surface layer frame, and the surface layer is fixed to the outer end face of the surface layer frame.

[0012] The pressure plate includes a heat insulation block and a pressure strip. The heat insulation block is adapted to and nested in the pressure groove. The pressure strip is fixed to the outer end face of the heat insulation block and extends outwards. A support column is fixed to the outer end face of the pressure strip. The outer end face of the support column is fixedly connected to the inner end face of the surface layer frame.

[0013] The window support frame includes a decorative panel and a support base. The decorative panel is fixed to the inner wall of the window and extends outward from the inner side of the wall to the surface layer. The support base is fixed to the decorative panel, and the outer end face of the support base is fixedly connected to the inner end face of the surface layer frame.

[0014] Furthermore, the surface frame has a mesh structure, including vertical keels and horizontal keels. The vertical keels are fixed to the ends of the cantilever frame and are parallel to the wall. The horizontal keels are fixed between adjacent vertical keels, so that the outer end faces of the horizontal keels and the vertical keels are on the same plane.

[0015] Furthermore, the insulation board has a window edge groove at the outer edge of the window, and a window edge strip is provided in the window edge groove. The window edge strip is L-shaped and includes a horizontal plate and a vertical plate arranged perpendicularly to each other. When the support is fixed on the decorative board, the support and the waterproof layer form a clamping area, so that the upper end face of the horizontal plate abuts against the support and the lower end face of the horizontal plate abuts against the waterproof layer, and the vertical plate is adapted to be nested in the window edge groove.

[0016] Furthermore, the support base has a U-shaped structure, including an inner side plate, an outer side plate, and a web plate. The inner side plate forms a clamping area with the waterproof layer, the outer side plate is fixedly connected to the surface layer frame, and the web plate is fixedly connected to the decorative panel.

[0017] Furthermore, the insulation boards are arranged at intervals to form grooves, and the direction of the grooves is either horizontal or vertical.

[0018] Furthermore, the pressure plate is provided with anchors, which pass through the pressure plate and are anchored in the wall.

[0019] Furthermore, the pressure strip, heat insulation block, and wall are all provided with corresponding anchoring holes, and heat insulation plugs are placed in the anchoring holes. The anchors anchor the pressure plate to the wall through the anchoring holes.

[0020] A construction method for an external wall insulation board waterproof and breathable membrane structure includes the following steps:

[0021] S1: Base surface treatment;

[0022] Clean the walls, removing dust, dirt, and loose material. Use grout to repair obvious cracks and damage to keep the walls clean and intact.

[0023] S2: Leveling layer;

[0024] Apply premixed mortar to the wall and use a trowel to smooth and polish the mortar to make its surface smooth and flat, thus obtaining a leveling layer;

[0025] S3: Fixed layer;

[0026] Apply bonding mortar or adhesive evenly to the leveling layer to obtain the fixing layer;

[0027] S4: Insulation layer;

[0028] Lay the insulation board on the fixed layer and use a compaction tool to fully adhere the insulation board to the fixed layer to avoid gaps or voids.

[0029] Rock wool nails are used to anchor the insulation board at the gaps. The rock wool nails are inserted into the wall to make the insulation board securely fixed and to obtain the insulation layer.

[0030] When fixing the insulation board, grooves are set on the insulation layer;

[0031] S5: Waterproof layer;

[0032] The waterproof and breathable membrane is laid flat and fixed to the insulation board with adhesive. The edges of the waterproof and breathable membrane are folded into the edges of the insulation layer, the window edges and the groove to form a complete and continuous waterproof layer.

[0033] S6: Fixed pressure plate;

[0034] Assemble the pressure plate, then embed the heat insulation block on the pressure plate into the pressure groove, tap the pressure plate to make the heat insulation block fit tightly with the pressure groove, and make the pressure strip press on the fold of the waterproof and breathable membrane.

[0035] Fix the support column to the outer end face of the pressure plate;

[0036] S7: Fixed window support frame;

[0037] Fix decorative panels to the inner walls around the window, and fix support bases to the decorative panels so that the inner end face of the support bases abuts against the waterproof layer;

[0038] S8: Fixed curtain wall frame;

[0039] The mounting bracket is wrapped around the insulation layer and fixed to the wall, with the mounting bracket pressing over the fold of the waterproof and breathable membrane;

[0040] Fix the cantilever frame to the fixed frame, and fix the surface shelf to the end of the cantilever frame;

[0041] Securely connect the shelf to the support column, and securely connect the shelf to the support base;

[0042] S9: Fixed surface layer;

[0043] Secure the surface layer to the frame and check the firmness of the surface layer to the curtain wall frame to ensure the stability of the surface layer.

[0044] Furthermore, in S6, after the pressure plate is tightened, holes are drilled into the wall on the pressure plate to obtain anchoring holes, and heat insulation plugs are placed in the anchoring holes; the anchors are installed to anchor the pressure plate to the wall, and the heat insulation plugs in the anchoring holes are crushed to form a heat insulation layer that wraps around the anchors.

[0045] Furthermore, in S7, a window edge strip is also provided. After the decorative panel is fixed, the vertical plate of the window edge strip is embedded into the window edge groove and presses down the edge of the waterproof and breathable membrane. The horizontal plate is pressed so that the lower end of the horizontal plate abuts against the waterproof layer.

[0046] Place the support base against the upper surface of the horizontal plate and fix the support base to the decorative plate, so that the support base and the waterproof layer form a clamping area and limit the window edge strip.

[0047] The beneficial effects of the above technical solution are:

[0048] (1) This invention fixes the fixing frame to the walls around the insulation board, uses a cantilevered method to erect the surface layer frame, and uses pressure plates and window support frames to set the central support points. This allows for proper fixing of the surface layer without damaging the insulation and waterproof layers, avoiding the damage to the waterproof and breathable membrane that may be caused by anchors in conventional construction. It effectively prevents water penetration, ensuring the integrity of the waterproof layer, reducing the risk of leakage, and thus protecting the stability of the building structure and internal wall materials, extending the building's service life. Furthermore, the waterproof and breathable membrane is pasted onto the insulation board and folded inwards towards the edges of the insulation board, the grooves, and the window edges, and is respectively pressed and fixed by the fixing frame, pressure plates, and window support frames, ensuring the continuity, integrity, reliability, and firmness of the waterproof layer.

[0049] (2) This invention incorporates grooves and plates on the insulation board to provide support points for the surface layer frame. To minimize the impact of the grooves and plates on the insulation layer, the embedded portion of the plates is designed as a heat-insulating block with thermal insulation properties, reducing the heat conduction efficiency at the grooves and ensuring the continuity and integrity of the insulation layer, effectively preventing the formation of thermal bridges. Furthermore, during the installation of the curtain wall frame, it is not directly anchored to the prepared insulation layer, ensuring the integrity of the insulation layer, enhancing its insulation performance, and avoiding thermal bridge effects at the anchoring points. This provides excellent insulation while preventing damage to the wall structure from thermal bridges, increasing the durability of the wall structure. Attached Figure Description

[0060] Example 1: This example aims to provide a construction structure and method for a waterproof and breathable membrane for exterior wall insulation boards. It is mainly used for setting up exterior wall insulation and waterproofing structures on the exterior walls of buildings. It addresses the problem that fixing the waterproof and breathable membrane 3 and the surface layer 7 in traditional exterior wall waterproofing and insulation systems can damage the waterproof and insulation layers, resulting in water leakage and thermal bridging.

[0061] An external wall insulation board waterproof and breathable membrane construction structure includes a wall 1, an insulation board 2, a waterproof and breathable membrane 3, a pressure plate 4, a window support frame 5, a curtain wall frame 6, and a surface layer 7.

[0062] like Figure 1 A window 101 is opened in the middle of wall 1. The left and right parts of wall 1 turn and extend in different directions. A waterproof and heat-insulating structure is required on the outer surface of the middle and left parts of wall 1; for example Figure 6 A leveling layer 11 is obtained by applying and smoothing mortar on the surface of wall 1, and then a fixing layer 12 is obtained by evenly applying polymer adhesive mortar on the leveling layer 11. Alternatively, adhesives or adhesive liquids can be used.

[0063] Insulation board 2 is fixed to the surface of wall 1 through leveling layer 11 and fixing layer 12. Insulation board 2 is rock wool board. The insulation boards 2 are arranged continuously adjacent to each other, and rock wool nails are anchored at the joints. The rock wool nails penetrate into the wall 1 to reinforce the insulation board 2 and form an insulation layer. Figure 2 Some adjacent insulation boards 2 are arranged at intervals to form grooves, so that the insulation layer has multiple horizontal or vertical rectangular grooves 201. In other embodiments, the grooves 201 can also be obtained by excavating on the insulation board 2. The grooves 201 obtained in this way are not limited to horizontal or vertical, and the cross section can also be rectangular, semi-circular, etc.

[0064] The waterproof and breathable membrane 3 is adhered to the insulation layer with epoxy-based spray adhesive. The edges of the waterproof and breathable membrane 3 are folded inward toward the edges of the insulation layer, the edges of the window 101, and the groove 201 to form a waterproof layer.

[0065] The curtain wall frame 6 includes a fixed frame 601, a cantilever frame 602, and a surface shelf 603. All three components—fixed frame 601, cantilever frame 602, and surface shelf 603—are made of aluminum. Figure 4 The fixing frame 601 is fixed to the wall 1 with expansion bolts. The cantilever frame 602 is fixed to the fixing frame 601 with spacer bolts and extends outward from the wall. The end of the cantilever frame 602 is bolted to the surface layer frame 603. The surface layer frame 603 is a mesh structure, including vertical keel 604 and horizontal keel 605. The vertical keel 604 is fixed to the end of the cantilever frame 602 and is parallel to the wall 1. The horizontal keel 605 is fixed between adjacent vertical keels 604, so that the outer end face of the horizontal keel 605 and the vertical keel 604 is on the same plane. The surface layer 7 is bolted to the outer end face of the surface layer frame 603. The surface layer 7 is an aluminum decorative curtain wall panel.

[0066] The pressure plate 4 includes a heat insulation block 401 and a pressure strip 402. The heat insulation block 401 is an aluminum thermal break heat insulation plate, such as... Figure 6 The heat insulation block 401 is adapted to and nested in the pressure groove 201. The pressure strip 402 is a rectangular aluminum plate, and the pressure strip 402 is fixed to the outer end face of the heat insulation block 401 with screws and extends outwards. Figure 3 The outer end face of the pressure strip 402 is welded and fixed with a support column 403. The support column 403 is a square column, or it can be a U-shaped channel steel or an I-beam. The support column 403 is connected to the inner surface of the surface shelf 603 with screws.

[0067] Window support frame 5 includes a decorative panel 501 and a support base 502, such as Figure 3 Decorative panel 501 is fixed to the inner wall of window 101 with expansion screws. Decorative panel 501 extends outward from the inner side of wall 1 to surface layer 7. Support base 502 is bolted to decorative panel 501. The outer end face of support base 502 is fixedly connected to the inner end face of surface layer frame 603. Support base 502 has a U-shaped structure, uses channel steel, and includes inner side plate 5021, outer side plate 5022, and web plate 5023. Inner side plate 5021 forms a clamping area with the waterproof layer. Outer side plate 5022 is screwed to surface layer frame 603. Web plate 5023 is screwed to decorative panel 501.

[0068] A construction method for an external wall insulation board 2 and a waterproof and breathable membrane 3 structure includes the following steps:

[0069] S1: Base surface treatment;

[0070] Clean wall 1, removing dust, dirt and loose material, and use grout to repair obvious cracks and damage in wall 1, so that wall 1 remains clean and intact;

[0071] S2: Leveling layer 11;

[0072] Apply premixed mortar to wall 1, and use a trowel to smooth and polish the premixed mortar to make its surface smooth and flat, thus obtaining leveling layer 11;

[0073] S3: Fixed layer 12;

[0074] Apply adhesive mortar or adhesive evenly to the leveling layer 11 to obtain the fixing layer 12;

[0075] S4: Insulation layer;

[0076] like Figure 2 Insulation board 2 is laid on the fixed layer 12, and the insulation board 2 is fully adhered to the fixed layer 12 with a compaction tool to avoid gaps or voids.

[0077] Rock wool nails are used to anchor the insulation board 2 at the gaps. The rock wool nails are inserted into the wall 1 to make the insulation board 2 securely fixed and to obtain the insulation layer.

[0078] When fixing the insulation board 2, a groove is opened or reserved on the insulation board 2 so that the insulation layer has a groove 201;

[0079] S5: Waterproof layer;

[0080] The waterproof and breathable membrane 3 is laid flat and fixed to the insulation board 2 with adhesive. The edges of the waterproof and breathable membrane 3 are folded into the edge of the insulation layer, the edge of the window 101 and the groove 201 to form a complete and continuous waterproof layer.

[0081] S6: Fixed pressure plate 4;

[0082] like Figure 3 Assemble the pressure plate 4, then embed the heat insulation block 401 on the pressure plate 4 into the pressure groove 201, and tap the pressure plate 4 to make the heat insulation block 401 fit tightly with the pressure groove 201, and make the pressure strip 402 press on the fold of the waterproof and breathable membrane 3.

[0083] Fix the support column 403 to the outer end face of the pressure plate 4;

[0084] S7: Fixed window support frame 5;

[0085] A decorative panel 501 is fixed on the inner wall around the window 101, and a support 502 is fixed on the decorative panel 501 so that the inner end face of the support 502 abuts against the waterproof layer.

[0086] S8: Fixed curtain wall frame 6;

[0087] like Figure 4The fixing bracket 601 is wrapped around the insulation layer and fixed to the wall 1, and the fixing bracket 601 is pressed onto the fold of the waterproof and breathable membrane 3;

[0088] Fix the cantilever frame 602 to the fixed frame 601, and fix the surface shelf 603 to the end of the cantilever frame 602;

[0089] The shelf 603 is fixedly connected to the support column 403, and the shelf 603 is fixedly connected to the support base 502;

[0090] S9: Fixed surface layer 7;

[0091] like Figure 1 Fix the surface layer 7 on the surface layer frame 603 and check the firmness of the surface layer 7 and the curtain wall frame 6 to ensure the stability of the surface layer 7.

[0092] Example 2 is basically the same as Example 1, except that a window edge strip 8 is added and some structures are optimized. This example further describes the structure.

[0093] To better seal the waterproof and breathable membrane 3 at the edge of window 101, such as Figure 7 A window pressing groove 202 is provided on the outer edge of the window 101 in the insulation board 2. A window pressing strip 8 is provided in the window pressing groove 202. The window pressing strip 8 is L-shaped and includes a horizontal plate 801 and a vertical plate 802 arranged perpendicularly to each other. The horizontal plate 801 and the vertical plate 802 are integrally molded by injection molding. When the support seat 502 is fixed on the decorative board 501, the support seat 502 and the waterproof layer form a clamping area, so that the upper end face of the horizontal plate 801 abuts against the support seat 502 and the lower end face of the horizontal plate 801 abuts against the waterproof layer. The vertical plate 802 is adapted to be nested in the window pressing groove 202. In step S7, after fixing the decorative panel 501, the vertical plate 802 of the window edge strip 8 is embedded into the window edge groove 202 and presses down the edge of the waterproof and breathable membrane 3. The horizontal plate 801 is pressed down so that the lower end face of the horizontal plate 801 abuts against the waterproof layer. Then the support seat 502 abuts against the upper end face of the horizontal plate 801 and is fixed to the decorative panel 501 so that the support seat 502 and the waterproof layer form a clamping area and limit the window edge strip 8.

[0094] The pressure groove 201 is obtained by excavating on the insulation board 2. The direction of the pressure groove 201 is diagonally staggered, and the direction of the pressure plate 4 is correspondingly diagonally arranged. The surface layer frame 603 is a mesh steel frame that is diagonally staggered with the pressure strip 402. The support column 403 that is fixedly connected between the surface layer frame 603 and the pressure strip 402 is arranged at intervals according to the direction of the pressure plate 4 and the surface layer frame 603, which can meet the different artistic shape requirements of the surface layer 7.

[0095] To improve the fixing firmness between the pressure plate 4 and the groove, an anchor 9 is fixed on the pressure plate 4. The anchor 9 is an expansion screw. The pressure strip 402, the heat insulation block 401 and the wall 1 are all provided with corresponding anchor holes. Heat insulation plug 13 is placed in the anchor holes. In step S6, after the pressure plate 4 is tightened, a hole is drilled in the pressure plate 4 into the wall 1 to obtain the anchor hole, and the heat insulation plug 13 is placed in the anchor hole. The anchor 9 is installed to anchor the pressure plate 4 to the wall 1, and the heat insulation plug 13 in the anchor hole is crushed to form a heat insulation layer that wraps the anchor 9, so as to avoid the formation of a thermal bridge effect at the anchor 9.
