Description

Technical Field

[0001] This invention relates to a zero-carbon building roof, and more particularly to a high-efficiency installation method for a zero-carbon prefabricated insulated wall panel. Background Technology

[0002] A modular zero-carbon building composite exterior wall cladding component, patent document number CN218346475U, includes a keel frame and a wall structure layer embedded within the keel frame. The inner and outer surfaces of the wall structure layer are flush with the keel frame. The keel frame is a hollow cuboid frame with connection ports on all four end faces. The wall structure layer includes lightweight concrete layers symmetrically arranged on both inner and outer sides, and an insulation layer between the lightweight concrete layers. Tie bars and connectors are pre-embedded within the wall layer, and the connectors extend to the outside of the keel frame through the connection ports. Structural panels are connected to the inner and outer surfaces of the wall structure layer and the keel frame. The wall structure layer also includes an architectural metal mesh, which is disposed on the outer surface of one or both lightweight concrete layers. The structural panels are any one of calcium carbonate boards, concrete boards, or foamed ceramic boards. The integrated wall structure is prepared by first welding a layer of lightweight steel mesh to one side of the keel frame, then horizontally pouring a 5cm thick layer of lightweight concrete on the mesh. Before pouring, the connecting steel bars are pre-embedded through the connection points. Next, the insulation layer is placed horizontally on the bottom lightweight concrete layer, and then lightweight concrete is poured again. The wall layer formed by the inner and outer lightweight concrete layers and the inner insulation layer has the same thickness as the keel frame. The keel frame is a hollow square frame made of lightweight steel keel, welded together from various sections of lightweight steel keel.

[0003] Research has revealed that although the insulated wall adopts an overall prefabricated structure, which is convenient for on-site installation, there are still shortcomings in high-quality and efficient prefabricated installation, especially the defect of low overall strength of the fireproof and insulated main wall. Summary of the Invention

[0004] The purpose of this invention is to overcome the above-mentioned defects of the prior art, and to provide a high-quality and efficient installation method for prefabricated thermal insulation wall panels in zero-carbon buildings, and to overcome the defect of low overall strength of fireproof and thermal insulation main walls.

[0005] To achieve the above objectives, this invention provides a high-efficiency installation method for zero-carbon prefabricated insulated walls. Its key feature is the embedded fire-resistant and heat-insulating main panel within the wall frame. High-strength fire-resistant and heat-insulating secondary panels, crack-resistant leveling mortar layers, and decorative layers are respectively installed outwards on both sides of the main panel. The embedded fire-resistant and heat-insulating main panel forms the fire-resistant and heat-insulating main wall, while the high-strength fire-resistant and heat-insulating secondary panels on both sides form the fire-resistant and heat-insulating secondary wall surface, significantly enhancing the heat insulation and fire resistance performance. The crack-resistant leveling mortar layer and decorative layer provide stable protection for the fire-resistant and heat-insulating secondary wall surface.

[0006] The high-strength fireproof insulation sub-board and crack-resistant leveling mortar layer are installed as follows: First, non-metallic thermal break connectors are horizontally installed through the main fireproof insulation board and the two high-strength fireproof insulation sub-boards. The two screw ends of the non-metallic thermal break connectors are screwed onto the inner limiting fastening plates. Then, a wire mesh is hung. Before or after hanging the wire mesh, at least one limiting pad is embedded on the inner side of the wire mesh between the inner limiting fastening plates to limit the distance to the high-strength fireproof insulation sub-board. The two screw ends of the non-metallic thermal break connectors are screwed onto the outer limiting fastening plates of the wire mesh, which are opposite to the inner limiting fastening plates, and then smoothed with crack-resistant leveling mortar. This significantly enhances the structural strength of the wall and ensures the overall stability of the wall. The entire wire mesh tightening process only requires tightening the limiting fastening plates, which is highly conducive to high-efficiency prefabricated installation. The mutually aligned limiting and fastening discs and limiting pads are densely spaced and equipped with limiting and fastening steel wires. Then, the anti-crack leveling mortar is solidified, which can significantly enhance the overall strength of the wall surface and overcome the defect of low overall strength of the fireproof and heat-insulating main wall.

[0007] This high-strength fireproof insulation sub-board, tightly connected to the main fireproof insulation board, better ensures and enhances insulation and fire resistance. The transversely penetrating non-metallic thermal break connectors, their end-mounted limiting fasteners, and the fixed wire mesh significantly improve the overall strength of the fireproof insulation and facilitate rapid prefabricated construction. Furthermore, the crack-resistant leveling mortar firmly fixes the fireproof insulation sub-board and wire mesh together, and the solidified limiting fasteners and shims of the crack-resistant leveling mortar layer will not loosen, greatly improving resistance to deformation and making the decorative layer more durable, significantly extending the service life of the entire wall. It overcomes the deficiency of low overall strength in the fireproof insulation main wall, offering advantages such as stable overall wall strength and insulation performance, good weather resistance and fire resistance, long service life, and high-efficiency prefabricated installation.

[0008] Preferred method: Before smoothing with crack-resistant leveling mortar, first apply a layer of cement 107 adhesive mixed with water droplets to the surface of the high-strength fireproof insulation sub-board, and then smooth with crack-resistant leveling mortar. The cement 107 adhesive mixed with water droplets should be applied in a sparse manner. Ideally, after spraying the water droplets, spaced water droplets should form on the surface of the high-strength fireproof insulation sub-board. This promotes rapid and stable bonding between the high-strength fireproof insulation sub-board surface and the leveling cement mortar. The applied cement mortar leveling layer not only ensures rapid stabilization and the proper smoothing performance of the crack-resistant leveling mortar, but also provides greater stability and durability.

[0009] As an optimization, adjacent fireproof insulation main boards and adjacent high-strength fireproof insulation sub-boards are bonded with fireproof adhesive, which helps ensure overall compressive fire resistance and durability. Adjacent wire meshes are clamped together using inner and outer limiting fastening discs, which helps strengthen the overall structural strength. The fireproof insulation main boards are B1-grade fireproof insulation boards, and the high-strength fireproof insulation sub-boards are high-strength A-grade fireproof insulation boards. This significantly improves fire resistance. The fireproof adhesive bonding uses fireproof expanding foam, which is beneficial for both fire protection and heat insulation.

[0010] As an optimization, overlapping wires of adjacent wire meshes are anchored to further enhance the overall strength of the wall; fireproof and thermal insulation main boards are bonded and embedded within the wall frame to make the main wall more stable; the edges of the wire mesh are fixed to the wall frame, significantly enhancing the overall strength of the wall. The bonding is done with a fireproof adhesive.

[0011] As an optimization, the high-strength fireproof insulation sub-board and the fireproof insulation main board are bonded together with fireproof adhesive, which improves the structural strength and fire resistance of the wall. The use of fireproof expanding foam for bonding further ensures the fireproof and insulation performance. Before or after hanging the wire mesh, a limiting pad is embedded on the inner side of the wire mesh between the inner limiting fastening plates to limit the distance to the high-strength fireproof insulation sub-board. The one-to-one spacing between the inner and outer limiting fastening plates and the limiting pad ensures the wire mesh is locked and secured, guaranteeing the stability of the entire wall.

[0012] As an optimization, the limiting and fastening disc has at least three concentrically spaced bottom rings with at least three circumferentially evenly distributed radial end face teeth facing the wire mesh. The outer circumference of the internally threaded circular tube extending from the inner circumferential end face of the inner ring is connected to the inner end of the radial end face teeth, which can significantly improve the support, limiting and fastening capacity; or at least three circumferentially evenly distributed sloping radial arms facing the wire mesh with a lower outer slope and a higher inner slope are provided between the inner circumference of the outer bottom ring and the outer circumference of the internally threaded center circular tube, which is easy to tighten.

[0013] As an optimization, both the radial end face toothed arms and the inclined radial arms are five in number, evenly distributed circumferentially. This ensures both sufficient solidification space for the crack-resistant leveling mortar and adequate contact and limiting support between the radial end face toothed arms and the inclined radial arms and the wire mesh.

[0014] As an optimization, the radial end face toothed arms are radial end face toothed arms that face and clamp the wire mesh wires, significantly improving the clamping performance of the wire mesh; all the wavy radial arms are wavy curved wavy radial arms that are simultaneously zigzag-bent and extruded into the wire mesh wires, making it easier to tighten and limit the crack-resistant leveling mortar at the fastening disc. All the wavy curved wavy radial arms consist of an inner base section extending radially along the outer circumference of the internally threaded central circular tube, a middle arc bend section that curves clockwise from the outer end of the inner base section, and an outer arc bend section that curves counterclockwise from the outer end of the middle arc bend section or an outer tail section extending radially from the outer end of the middle arc bend section. This makes it very convenient to screw in under the resistance of the wires, which is more conducive to quick installation.

[0015] As an optimization, the limiting fastening disc is equipped with at least three evenly distributed ring-shaped wrenches, the number of which is the same as the number of radial end face toothed arms or ramp radial arms of the limiting fastening disc, and is used to insert into the space of adjacent radial end face toothed arms or ramp radial arms. This allows for faster tightening of the limiting fastening disc and increased tightening force.

[0016] As an optimization, the limiting pad is a central support extending upward from the center of a circular base to support the wire mesh. On either side of the central support, a pair of U-shaped arms with inward-facing openings and at the same height as the central support, also support the wire mesh. The two sides of each U-shaped arm extend upward to embed the wire mesh into two limiting arms. This design provides good limiting and support performance, and better stability after the crack-resistant leveling mortar has solidified.

[0017] As an optimization, the circular base is further equipped with another pair of U-shaped supports on both sides of the central support, with openings facing inwards and at the same height as the central support. The two sides of this second pair of U-shaped supports extend upwards and are fitted with wire mesh and steel wire for limiting. This provides better limiting and support performance, and the stability is better after the crack-resistant leveling mortar has solidified.

[0018] After adopting the above technical solution, the high-quality and efficient installation method of the zero-carbon building prefabricated thermal insulation wall of the present invention overcomes the defect of low overall strength of the fireproof and thermal insulation main wall, and has the advantages of good overall strength stability and thermal insulation performance, good weather resistance and fire resistance, long service life, and high-quality and efficient prefabricated installation.

Detailed Implementation

[0020] Example 1, as Figure 1-6 As shown, the high-efficiency installation method of the zero-carbon building prefabricated thermal insulation wall of this invention involves embedding a fireproof thermal insulation main board 1 within the wall frame. High-strength fireproof thermal insulation secondary boards 2, crack-resistant leveling mortar layers 3, and decorative layers 4 are respectively installed outwards on both sides of the fireproof thermal insulation main board 1. The fireproof thermal insulation main board embedded within the wall frame forms the fireproof thermal insulation main wall, and the high-strength fireproof thermal insulation secondary boards on both sides form the fireproof thermal insulation secondary wall surface, significantly enhancing thermal insulation and fire resistance. The crack-resistant leveling mortar layer and decorative layer protect the fireproof thermal insulation secondary wall surface. Interlocking limiting fastening discs and limiting pads are densely arranged with limiting fastening steel wires, and then solidified with crack-resistant leveling mortar, which significantly strengthens the overall strength of the wall surface and overcomes the defect of low overall strength of the fireproof thermal insulation main wall.

[0021] The high-strength fireproof insulation sub-board 2 and crack-resistant leveling mortar layer 4 are installed as follows: First, non-metallic thermal break connectors 5 are horizontally installed through the fireproof insulation main board 1 and the two high-strength fireproof insulation sub-boards 2. The two screw ends of the non-metallic thermal break connector 5 are screwed and tightened with inner limiting fastening plates 61. Then, a wire mesh 7 is hung. Before or after hanging the wire mesh 7, a limiting pad 8 is embedded inside the wire mesh 7 between the non-metallic thermal break connectors 5 to limit the distance to the high-strength fireproof insulation sub-board 2. The two screw ends of the non-metallic thermal break connector 5 are screwed and tightened with outer limiting fastening plates 62, which are opposite to the inner limiting fastening plates 61. Finally, crack-resistant leveling mortar is used to smooth the surface. This significantly enhances the structural strength of the wall and ensures its stability. The entire wire mesh tightening process only requires tightening the limiting fastening plates, which is very beneficial for prefabricated construction.

[0022] This high-strength fireproof insulation sub-board, tightly connected to the main fireproof insulation board, better ensures and enhances insulation and fire resistance. The transversely penetrating non-metallic thermal break connectors, their end-mounted limiting fasteners, and the fixed wire mesh significantly improve the overall strength of the fireproof insulation and facilitate rapid prefabricated construction. Furthermore, the crack-resistant leveling mortar firmly fixes the fireproof insulation sub-board and wire mesh together, and the solidified limiting fasteners and shims of the crack-resistant leveling mortar layer will not loosen, greatly improving resistance to deformation and making the decorative layer more durable, significantly extending the service life of the entire wall. It overcomes the deficiency of low overall strength in the fireproof insulation main wall, offering advantages such as stable overall wall strength and insulation performance, good weather resistance and fire resistance, long service life, and high-efficiency prefabricated installation.

[0023] Specifically, adjacent fireproof and heat-insulating main boards 1 and adjacent high-strength fireproof and heat-insulating secondary boards 2 are bonded with fireproof adhesive, and adjacent wire mesh 7 are clamped together by inner and outer limiting fastening plates 61 and 62; the fireproof and heat-insulating main board 1 is a B1-grade fireproof insulation board, and the high-strength fireproof and heat-insulating secondary board 2 is a high-strength A-grade fireproof insulation board. The fireproof adhesive bonding uses fireproof foam adhesive, which is beneficial for fire prevention and heat insulation.

[0024] Specifically, the overlapping wires of adjacent wire mesh 7 are anchored together, and the fireproof and thermal insulation main board 1 is bonded and embedded inside the wall frame, with the edges of the wire mesh 7 fixed to the wall frame. The high-strength fireproof and thermal insulation sub-board 2 is bonded to the fireproof and thermal insulation main board 1 with a fireproof adhesive. Preferably, before smoothing with crack-resistant leveling mortar, a layer of cement 107 adhesive mixed with water slurry is applied to the surface of the high-strength fireproof and thermal insulation sub-board, and then smoothed with crack-resistant leveling mortar. The cement 107 adhesive mixed with water slurry layer is sprayed sparsely. Ideally, after spraying the water slurry, spaced water slurry droplets form on the surface of the high-strength fireproof and thermal insulation sub-board, which promotes rapid and stable bonding between the surface of the high-strength fireproof and thermal insulation sub-board and the leveling cement mortar. The cement mortar leveling layer not only allows for rapid stabilization and normal performance of the crack-resistant leveling mortar, but also provides greater stability and durability.

[0025] Specifically, the limiting and fastening discs 61 and 62 consist of three concentrically spaced bottom rings with five circumferentially evenly distributed radial end face teeth facing the wire mesh 7. An internally threaded circular tube extending from the inner circumferential end face of the inner ring connects to the inner end of each radial end face tooth. Each radial end face tooth faces and clamps the wires of the wire mesh 7. The limiting and fastening discs 61 and 62 are equipped with five evenly distributed ring-shaped handles, the number of which is the same as the number of radial end face teeth or ramp radial arms on the limiting and fastening discs, and are used to insert into the space of adjacent radial end face teeth or ramp radial arms.

[0026] Specifically, the limiting pad 8 is a central support extending upward from the center of a circular base to support the wire mesh 7. A pair of U-shaped support arms with inward-facing openings and the same height as the central support are provided on both sides of the circular base to support the wire mesh 7. The two sides of the U-shaped support arms extend upward to embed the two limiting arms of the wire mesh 7.

[0027] like Figure 7 As shown, in the high-efficiency installation method of the zero-carbon building prefabricated thermal insulation wall of the present invention, the second type of limiting fastening discs 61 and 62 are five circumferentially evenly distributed, sloping radial arms facing the wire mesh 7, with the outer edge lower than the inner edge, set between the inner circumference of the outer circular bottom ring and the outer circumference of the inner threaded central circular tube. All sloping radial arms are wavy, simultaneously needle-bent, wavy curved sloping radial arms of the extruded wire mesh 7. All wavy curved sloping radial arms are composed of an inner base section extending radially from the outer circumference of the inner threaded central circular tube, a middle arc bend section that curves clockwise from the outer end of the inner base section, and an outer arc bend section that curves counterclockwise from the outer end of the middle arc bend section or an outer tail section extending radially from the outer end of the middle arc bend section.

[0028] like Figure 8 As shown, the difference between the second type of limiting pad and the limiting pad 8 in the first embodiment of the high-efficiency installation method of zero-carbon building prefabricated thermal insulation wall in this invention is that the circular base is provided with another pair of U-shaped support arms on both sides of the central support column, which are perpendicular to the aforementioned pair of U-shaped support arms and have inward openings, and are at the same height as the central support column. The two sides of the other pair of U-shaped support arms extend upward and are respectively fitted with steel wire mesh 7 steel wire limiting arms.

[0029] In summary, the high-efficiency installation method for zero-carbon prefabricated insulated walls of this invention overcomes the defects of low overall strength of the fireproof and insulated main wall, and has the advantages of good overall strength stability and thermal insulation performance, good weather resistance and fire resistance, long service life, and high-efficiency prefabricated installation.
