Description

Technical Field

[0001] The invention relates to the technical field of window construction, and in particular to a construction method for a heavy-weight window based on a thermal insulation integrated window sill. Background Art

[0002] At present, the quality of residential projects is constantly upgraded, the indoor lighting effect continues to expand, and the types and weights of windows are also increasing accordingly. At present, thermal insulation integration is also an advanced practice promoted by construction owners. For installing heavy windows on the thermal insulation integrated window sills of the exterior wall AAC boards, the middle part of the structural method of the thermal insulation integrated window sills of the AAC boards is thermal insulation material, which lacks bearing capacity. The bearing capacity of the window sill cannot meet the requirements or the window sill cracks, etc., and there is a risk of leakage, thereby reducing the user experience. The present invention takes effective measures to increase the bearing capacity of the window sill, and at the same time uses the sealing method of the junction of different materials to reduce leakage. Summary of the invention

[0003] The purpose of the present invention is to provide a construction method for heavy-weight windows based on thermal insulation integrated window sills, so as to solve the problem proposed in the above background technology that the current practice is only to add a concrete slab on the AAC thermal insulation integrated window sill, and to improve the bearing capacity of the window sill by the concrete itself. In this case, a cold bridge phenomenon will occur at the position of the concrete slab due to the lack of thermal insulation material, thereby reducing the user experience.

[0004] To achieve the above object, the present invention provides the following technical scheme: a construction method for heavy-weight windows based on thermal insulation integrated window sills, comprising an interior surface layer, an AAC board, anchoring steel bars, a 5 mm thick waterproof mortar leveling, an 8 mm thick steel plate, a silicone weather-resistant sealing board, polyurethane foam filling, dry hard waterproof mortar caulking, 30 thick thermal insulation mortar, 1.5 thick acrylic waterproof coating, 6 thick waterproof mortar leveling, a two-component waterproof sealant, a sandwich insulation layer, and an exterior surface layer; comprising the following steps: Step 1: Install AAC thermal insulation integrated window sill; Step 2: Drill holes and install embedded parts; Step 3: Install the fixed bearing member; Step 4: Install the attached frame; Step 5: Waterproofing and closing of exterior windows; Step 6: Install the main frame glass; Step 7: Glue treatment.

[0005] Preferably, the precise position and size of the windowsill are determined by marking the size and position of the protruding part of the exterior wall, a special adhesive is evenly applied behind the deepened AAC board, the position of the anchor is marked on the insulation board, and holes are drilled to install the anchor to ensure firmness. After installation, the gaps between the boards are filled with a special adhesive and compacted with force.

[0006] Preferably, according to the design requirements and the actual window sill position, the drilling position is accurately marked, the measurement and marking should be precise, and an electric drill is used to drill holes at the marked positions. The hole diameter and depth should be determined according to the size requirements of the embedded reinforcement. The speed and force should be controlled when drilling to prevent the plate from cracking. After drilling, the dust and debris in the hole should be removed to ensure that the hole is dry and clean. Then the embedded reinforcement is inserted into the hole to ensure that there is enough friction between the reinforcement and the hole wall. If necessary, a special adhesive can be used to fix the embedded reinforcement to increase its stability. Slowly pour the prepared cement slurry into the holes around the embedded reinforcement. Be careful not to generate bubbles. The grouting should be uniform to ensure that the slurry can fully fill the holes and surround the embedded reinforcement. After grouting, necessary maintenance is required to ensure the normal curing of the slurry.

[0007] Preferably, carefully check the flatness and strength of the base surface to ensure that there are no loose objects and pollutants, use waterproof mortar to level the base, ensure that the ground is flat and has good waterproof performance, calculate the corresponding steel plate bearing capacity according to the weight of the window, use steel plate bearing parts that meet the bearing capacity requirements, place the pre-prepared steel plate on the leveled base, ensure that the position and direction of the steel plate meet the requirements, and perform welding operations to firmly connect the embedded reinforcement and the steel plate through welding. The weld should be uniform and free of slag inclusions and cracks.

[0008] Preferably, a suitable fixing method is selected according to the wall material. For example, expansion screws may be used on concrete walls, while special plugs and cement nails may be required for brick walls. The auxiliary frame is aligned according to the pre-marked position, and holes are drilled at the marked points with an electric drill. The auxiliary frame is then fixed to the wall with screws or nails to ensure that each fixing point is firm and stable without any looseness. The part where the auxiliary frame contacts the wall is sealed with dry and hard waterproof mortar to seal the secret room. The auxiliary frame and the steel plate bearing member are sealed with waterproof sealant to ensure that the sealing performance of the entire auxiliary frame is good.

[0009] Preferably, before waterproofing construction, the outer window area is leveled with waterproof mortar to make the steel plate bearing part, the attached frame and the base layer solid and flat. During the waterproofing painting process, acrylic waterproof coating is evenly applied with a brush or roller. The coating thickness should be controlled at 1.5 mm to ensure that the coating covers every area that needs waterproofing, including the sides and upper mouth of the window. After the first coat of paint is dry, a second coat is cross-coated, which helps to close tiny pores and enhance the waterproofing effect. For window treatment, a trowel is used to evenly apply the thermal insulation mortar around the window that has been painted with waterproof coating to ensure that the mortar layer is smooth and has no hollows. This layer not only enhances the waterproofing effect, but also has a thermal insulation effect.

[0010] Preferably, place the main frame at the location of the window, use a screwdriver and hammer to fix it to the wall, make sure the main frame is level and vertical, carefully place the glass into the main frame, make sure the glass is fully inserted into the main frame, and then use rubber pads or other materials to fix it in place.

[0011] Preferably, the windows and gaps should be thoroughly cleaned before applying glue to remove dust and impurities to ensure that the sealant can adhere well. Use detergent and rag to clean the windows, and ensure that the gaps are dry and free of water marks. Use a glue gun to evenly apply the sealant to ensure that the glue layer is continuous without breakpoints. When fixing the window frame to the wall, fix the upper frame first and then the frame to improve the sealing effect. After applying the glue, use a scraper to level the sealant to ensure that its surface is smooth and beautiful, without bubbles and protrusions.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: compared with the traditional process, the present invention adopts embedded parts and pressure plates to replace the traditional window sill pressing process, and transmits the upper pressure to the thermal insulation integrated window sill in the form of bearing parts and anchoring parts, thereby improving the integrity of the window sill and avoiding problems such as window sinking and wall cracking due to insufficient bearing capacity of the thermal insulation part. In addition, the present invention also increases the thermal insulation performance of the window part in terms of energy saving and thermal insulation, reduces the occurrence of cold bridges in the window part by adopting thin thermal insulation mortar plastering, and greatly increases the indoor thermal insulation performance. The present invention adopts acrylic waterproof coating to strengthen the anti-leakage treatment of the window frame part, thereby reducing the leakage risk of the window part.
