Description

Technical Field

[0001] The present invention relates to the technical field of energy-saving construction, and more specifically, to a low-energy consumption exterior wall enclosure system and a construction method. Background Art

[0002] In the current construction market, there are many types of non-insulating and self-insulating blocks and wallboard materials, but each has obvious limitations and shortcomings; For example, traditional non-insulating blocks, such as autoclaved aerated concrete blocks and hollow bricks, have high strength, but their thermal insulation performance is often average and difficult to meet the high standards of energy conservation and thermal insulation in modern buildings. Therefore, in practical applications, these blocks usually require additional thermal insulation materials, which undoubtedly increases construction costs and complexity. On the other hand, although the insulation blocks have solved the problem of balancing strength and thermal insulation performance to a certain extent, during the masonry process at the construction site, due to improper node treatment, the phenomenon of cold and hot bridges frequently occurs, which seriously affects the overall thermal insulation effect of the wall. In addition, although the existing self-insulating blocks have moderate thermal conductivity, their strength is generally low, which is difficult to meet the requirements of high-rise buildings for the strength of wall materials; In terms of wall panels, ALC (autoclaved lightweight aerated concrete) boards, as a common wall panel material, have certain thermal insulation properties. However, in order to meet higher insulation requirements, it is often necessary to build a thin plastering external insulation system or add thermal insulation and decorative integrated panels on the basis of the ALC board exterior wall. These additional insulation measures not only increase the construction period, but also significantly increase the overall construction cost.

[0003] In summary, the non-insulating and self-insulating blocks and wallboard materials currently on the market have defects to varying degrees in practical applications, especially in terms of controlling the thermal insulation performance at the cold and hot bridges and reducing the overall heat transfer coefficient, which makes it difficult to meet the comprehensive requirements of modern buildings for energy saving, environmental protection and economic benefits. Therefore, a low-energy consumption exterior wall enclosure system and construction method are urgently needed. Summary of the invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a low-energy consumption exterior wall enclosure system and a construction method to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a low-energy consumption exterior wall enclosure system, comprising a concrete column beam composed of a frame column and a frame beam, wherein a mold-retaining integrated plate made of an aerogel composite thermal insulation material is arranged on the outside of the concrete column beam, and a hydrophobic coating made of a mixture of a polymer and nano-silicon dioxide particles is filled between the outside of the concrete column beam and the mold-retaining integrated plate, wherein the mold-retaining integrated plate is used as an outer template during the construction of the main structure beam column, and is fixed to the concrete structure by an anchor bolt, wherein the anchor bolt adopts a disc anchor bolt with a diameter of 80 mm and a length of 25 mm, and needs to be anchored in the concrete structure; Solid waste composite self-insulating wall panels are made of cement, fly ash, admixtures, waste glass fiber and polystyrene boards. Sawtooth-shaped slots are left on both sides of the wall panels for connecting the wall panels. The difference between the convex and concave grooves between the saw teeth is 20mm. The wall panels are connected by mutual engagement to ensure the continuity of the insulation layer. U-shaped clips are set on the upper and lower parts and joints of the wall panels for fixing. The installation spacing is 600mm. The U-shaped clips are made of galvanized steel cards with a hot-dip galvanized layer of ≥175g / ㎡; Lightweight aggregate insulation concrete is used for the casting of structural columns, frame columns, lintels, and cappings. The lightweight aggregate insulation concrete uses different particle sizes of broken coal gangue after expansion, sintering, and as coarse and fine aggregates of lightweight aggregate concrete, and hollow ceramic microspheres are added to mix. The strength and thermal insulation performance of the concrete must meet the design requirements; Among them, the joints between the mold-retaining integrated board, the solid waste composite self-insulating wall panel and the main structure, and between the wall panels are sealed by foam mortar and waterproof mortar.

[0006] Preferably, when the mold-protecting integrated board is reinforced, 40×80mm square wood is used vertically, ¢48×2.8mm steel pipe is used horizontally, and ¢14 tension bolts are used for reinforcement at a spacing of 450mm. The anchor bolts of the mold-protecting board are set according to the requirements of the external insulation specification, with no less than 6 per square meter; Before reinforcing the formwork integrated board, a layer of interface agent is evenly sprayed on the surface of the formwork integrated board. The interface agent is used to enhance the bonding force between the formwork integrated board and the subsequent mortar material to prevent delamination and falling off during use. It also has certain moisture-proof and mildew-proof functions. For the tension bolt holes of the mold-maintaining integrated board, after the tension bolts are installed, rubber plugs are used to seal them. A sealing strip is arranged inside the rubber plug, which can effectively prevent rainwater and air from penetrating into the mold-maintaining integrated board through the bolt holes while sealing the bolt holes.

[0007] Preferably, a 20 mm gap is reserved between the solid waste composite self-insulating wallboard and the frame beams and columns, and the insulation layer is densely filled with foam mortar within the thickness range, and the remaining parts are densely filled with waterproof mortar; Before installing the solid waste composite self-insulating wallboard, a layer of elastic buffer pad is laid on the wall base, wherein the elastic buffer pad is composited with rubber and polyurethane foam; When filling the 20mm gap reserved between the solid waste composite self-insulating wall panels and the frame beams and columns with foam mortar and waterproof mortar, a layered filling method is adopted. First, fill a layer of 10mm thick foam mortar, wait for it to initially solidify, and then fill it with waterproof mortar to ensure that the gap is filled more densely and avoid quality problems such as hollowing and cracks.

[0008] Preferably, polyurethane fireproof foam is applied around the door and window openings, and waterproof mortar is used to close the inside and outside, with a thickness ranging from 15mm to 20mm. A drip line is set on the upper opening as required, and the lower opening is subjected to slope treatment; After applying polyurethane fireproof foam around the door and window openings and sealing with waterproof mortar, a layer of waterproof and breathable membrane is pasted on the sealing joints.

[0009] Preferably, ¢6 steel bars are used as anchors between the protective shells on both sides of the solid waste composite self-insulating wall panels, with a longitudinal and transverse spacing of 600mm. ¢4@200 anti-cracking steel mesh is arranged inside the protective shell, and the composite self-insulating wall panels on the sides of the structural columns and frame columns are changed to groove-type.

[0010] Preferably, all the structural components of the structural columns, frame columns, top beams and lintels are made with tongues and grooves, the tongue and groove are located on the outer surface of the insulation layer, the depth is 10 mm, and the tongue and groove are sealed with sealant.

Check the flatness of the wall and seal it with alkali-resistant glass fiber mesh cloth and anti-cracking mortar or gypsum mortar.

[0012] Preferably, the mold-retaining integrated plate is cut using a professional cutting machine according to the size of the design drawing. The edges should be smooth after cutting, and any gaps after the plates are spliced ​​should be filled with a special filler.

[0013] Preferably, when installing the solid waste composite self-insulating wall panels, the panels are arranged vertically in sequence along the length direction of the wall panels, standard panels are used for large surfaces, and when the local size is smaller than the standard panels, they are cut according to the size requirements. The size after cutting must not be less than 200mm. When installing the wall panels, a 20mm gap is reserved, and the gap is filled with foam mortar on the inside and waterproof mortar on the outside.
