DETAILED DESCRIPTION

(15) As shown in FIG. 1, a fabricated leveling composite radiation energy-saving concrete wall includes a concrete wall 1 and further includes an insulation roll 2 wrapped on a surface of the concrete wall 1 and a veneer 3 having a surface attached to an outer surface of the insulation roll 2, and support members are uniformly arranged between the veneer 3 and the surface of the concrete wall 1 to prevent the insulation roll 2 from being crushed. The insulation system here may be arranged on one or two sides of the concrete wall 1. The veneer 3 here also plays a protective role in separating the insulation roll 2 from the outside.

(16) The veneer 3 is connected to the surface of the concrete wall 1 through the support members, and each support member is adjustable in size in a direction perpendicular to the veneer 3 and is provided with a locking device for locking the adjusted size. This can achieve adjustment as required to avoid crushing the insulation roll 2 or forming empty drums.

(17) The support members are hollow blocks filled with an insulation material to avoid the formation of cold bridges. The insulation material filled inside the hollow blocks in this embodiment is aerogel.

(18) As shown in FIGS. 4-6, the support members include edge support members 42 used for supporting edges of the veneer 3, corner support members 43 used for supporting corners of the veneer 3, and main support members 41 used for supporting portions of the veneer 3 except the edges and corners; one edge of each edge support member 42 is flush with an edge of the veneer 3, and each corner support member 43 has a corner matching a corner of the veneer 3; and edges of the support members inside the insulation roll 2 transition smoothly to avoid the occurrence of cracks in the insulation roll 2.

(19) Three types of support members are configured here for the following reasons: due to the uniform distribution of support members, some support members are inevitably distributed on the edges or corners of the veneer 3; and in order to accelerate the construction progress, holes on the insulation roll 2 that correspond to the support members have been drilled before mounting, the positions of the holes on the edges or corners cannot be adjusted on site, and as shown in FIG. 3, complete main support members 41 cannot be mounted in the holes on the edges or corners, so the edge support members 42 and the corner support members 43 are required to support the edges and corners of the veneer 3.

(20) As shown in FIGS. 4-6, in this embodiment, the main support member 41 is a circular flat box, the edge support member 42 is a semi-circular flat box, the corner support member 43 is a quarter circular flat box, and box covers of the edge support member 42 and the corner support member 43 are opened at straight edge positions on their sides and are respectively connected to the edge support member 42 and the corner support member 43 by insertion for easy opening.

(21) As shown in FIG. 4, the main support member 41 is a circular flat box with upper and lower surfaces parallel to the veneer 3, and the box cover and box body of the circular flat box are connected by threads. In this case, the distance between the box cover and the surface of the concrete wall 1 can be changed by rotation, and the distance can be locked by stopping the rotation. Note that the lead angle and friction angle of the threads of the box cover and the circular flat box should be well controlled. The friction angle should be greater than the lead angle to better lock the distance between the box cover and the concrete wall 1 after the rotation is stopped. Thicknesses of the edge support members 42 and the corner support members 43 can also be adjusted here. The method is to make the edge support members 42 and the corner support members 43 slightly thinner than the total thickness of the insulation roll 2, and then to change the thickness of a structural adhesive 6 brushed on two sides of the edge support members 42 and the corner support members 43.

(22) The support members should be made of a material having a low thermal conductivity, such as engineering plastics, and metal should not be used, otherwise weak cold bridges will still be formed even in the presence of the insulation material. When conditions do not permit, the support members can be made of local materials, such as wooden blocks.

(23) The support members are bonded to the veneer 3 and the surface of the concrete wall 1 respectively, and reinforcement bars 5 for strengthening the bonding effect are arranged on surfaces, in contact with the veneer 3 and the surface of the concrete wall 1, of the support members respectively. The reinforcement bars 5 are similar to ribs on ribbed steel bars or chiseled marks on a joint surface of new and old concrete.

(24) As shown in FIG. 2, a metal foil 21 is wrapped on two side surfaces of the insulation roll 2 respectively, the insulation roll 2 is connected to the metal foil 21 by a flexible adhesive, and the flexible adhesive fills a gap between the insulation roll 2 and the metal foil 21. In this embodiment, the metal foil 21 is an aluminum foil. Note that the metal foil 21 here not only functions to interrupt heat radiation, but also provides protection. Therefore, the metal foil should be thicker without affecting the bending of the insulation roll 2.

(25) The insulation roll 2 is an aerogel felt or a cross-linked polyethylene insulation pad; and the insulation roll 2 is a hydrophobic material to prevent wetting or water infiltration and achieve a waterproof effect. The flexible adhesive is a waterproof adhesive to prevent failure due to water exposure.

(26) In this embodiment, the insulation roll 2 is an inorganic insulation roll 2 such as a silica insulation roll 2, which has fine fluffs on the surface and does not stick to water like lotus leaves, making it a hydrophobic material.

(27) The flexible adhesive here refers to an adhesive that remains soft after curing. The flexible adhesive is used for two effects: first, avoiding affecting the bending of the insulation roll 2; and second, forming an adhesive film covering the surface of the insulation roll 2 to constrain and protect the surface of the insulation roll 2 and prevent powder drop and cracking. The flexible adhesive should be waterproof and fireproof to prevent failure after immersion in water or burning. The flexible adhesive may be an MS adhesive.

(28) The insulation roll 2 is stacked in multiple layers on the surface of the concrete wall 1. This aims to press conduits located on the surface of the concrete wall 1 under the insulation roll 2 without protrusions, thereby avoiding the occurrence of cold bridges. In this embodiment, two layers of insulation roll 2 are arranged on one side of the concrete wall 1, and the conduits can be pressed under the insulation roll 2 without protrusions by forming an avoidance port on only one layer of insulation roll 2 attached to the concrete wall 1, not on the two layers of insulation roll 2.

(29) A method for mounting an insulation system on an energy-saving building is used for the construction of the foregoing fabricated leveling composite radiation energy-saving concrete wall, and includes the following steps:

(30) As shown in FIG. 7, step 1: wall pipelines 7 are laid on a surface of a completed concrete wall 1 according to drawings;

(31) As shown in FIG. 8, step 2: a first layer of insulation roll 2 with holes in one-to-one correspondence to support members is bonded to the surface of the concrete wall 1, and an avoidance port is formed on the first layer of insulation roll 2 to expose the wall pipelines 7 and ensure that the wall pipelines 7 are located within an outer surface of the first layer of insulation roll 2. If a wire box needs to be mounted, the wire box should be flush with an outer surface of a veneer 3. In this case, when the wire box is not used, a layer of insulation roll 2 may be bonded to avoid the formation of cold bridges;

(32) As shown in FIG. 9, step 3: main support members 41 are bonded in the holes of the insulation roll 2 with a structural adhesive 6, and thicknesses of the main support members 41 are adjusted by rotation to ensure that tops of the main support members 41 are coplanar; then edge support members 42 and corner support members 43 are bonded with the structural adhesive 6, and a thickness of the structural adhesive 6 at bottoms of the edge support members 42 and the corner support members 43 is adjusted to ensure that tops of the edge support members 42 and the corner support members 43 are coplanar with the tops of the main support members 41;

(33) As shown in FIG. 10, step 4: a second layer of insulation roll 2 with holes in one-to-one correspondence to the support members is bonded to the first layer of insulation roll 2 to ensure that a thickness of the second layer of insulation roll 2 meets climate and technical requirements, and that an outer surface of the second layer of insulation roll 2 is located within a plane where the tops of the support members are located;

(34) As shown in FIG. 11, step 5: joints on the insulation roll 2 are sealed with aluminum foil tapes 22;

(35) As shown in FIG. 12, step 6: after the wall pipelines 7 are tested, a veneer 3 is bonded to the support members with the structural adhesive 6;

(36) As shown in FIG. 13, step 7: a decorative layer 8 is constructed on the veneer 3.

(37) Note that the concrete wall 1 here refers to all walls that require insulation on buildings, including ceilings.

Various modifications and improvements made by those of ordinary skill in the art without departing from the design spirit of the present invention shall fall into the protection scope determined by the claims of the present invention.
