According to the invention, the wall insulation board 20 is arranged on the main structure steel bars by adopting the plurality of anchoring pieces 10, and the polymer anti-crack mortar and the glass fiber mesh cloth are sequentially laid on the wall insulation board 20, so that the plastering layer 30 is formed, and the glass fiber mesh cloth has the characteristics of stable structure, alkali resistance, crack resistance and the like, so that the crack resistance of the wall insulation structure 100 is greatly enhanced; flexible waterproof putty is laid on the plastering layer 30, and waterproof paint is coated on the plastering layer, so that the waterproof performance of the wall heat-insulating structure 100 can be ensured, and meanwhile, the effect of attractive appearance is achieved; concrete is poured to form the wall body, so that the wall body heat insulation plate 20 and the wall body form a firm effective connection relationship through the anchoring parts 10, the problem that the existing wall body heat insulation system is not firm enough in connection is effectively solved, and the structural stability of the wall body heat insulation system is enhanced.
In an embodiment, the step S10 may specifically include:
s101, a plurality of anchoring pieces 10 penetrate through a wall insulation board 20, and the anchoring pieces 10 are bound on reinforcing steel bars;
and S102, connecting and fixing the anchoring parts 10 on the two adjacent wall insulation boards 20 through binding wires.
In this embodiment, a plurality of anchoring members 10 are arranged on the wall insulation board 20 in a plum blossom shape, the installation position on the wall insulation board 20 is punched at first, then the anchoring members 10 are plugged into the holes, the anchoring members 10 are fixed by using a card or a nut, and finally, the claw nuts are screwed on the anchoring members 10. After the anchoring member 10 is installed, the wall insulation board 20 is installed in such a manner that the internal and external corners are installed first and then the wall insulation board is installed sequentially from one side to the other side. The anchor 10 that is located wall insulation board 20 inboard ligatures on the reinforcing bar with the iron wire to prevent that the template is crooked, anchor 10 in the wall insulation board 20 outside respectively with the anchor 10 ligature connection on the adjacent wall insulation board 20, thereby make a plurality of wall insulation boards 20 interconnect and become a whole, strengthened wall insulation system's connection stability, prevent the condition that local wall insulation board 20 fracture or drop.
The typesetting of the wall insulation board 20 needs to be paid attention to reduce the splicing, and under the ordinary condition, the height of the wall insulation board 20 is required to be the height of a floor, so that the vertical splicing is avoided, and the horizontal splicing can be carried out. When the bottom of the wall insulation board 20 is installed, mortar is paved or joint pointing is carried out by the mortar after the installation; sponge strips or adhesive sealing tapes are filled and pressed in horizontal joints of the splicing joints of the wall insulation boards 20 during splicing; in order to avoid the phenomenon of slab staggering at the splicing part, the supporting vertical battens are placed at the splicing part of the vertical seams, and the battens are ensured to be straight.

In a preferred embodiment, the inner formwork and the outer formwork are respectively supported at two sides of a wall body steel bar structure, the inner formwork and the outer formwork are temporarily supported by a steel pipe after being subjected to verticality deviation correction, through holes are drilled outwards in the inner formwork by a pistol drill after adjustment is finished, PVC plastic sleeves are filled in the through holes, split bolts penetrate through the through holes, nuts are screwed at two ends of the split bolts respectively to fix the inner formwork and the outer formwork, cleaning ports are formed in the bottoms of the inner formwork and the outer formwork, fragments in the formwork are cleaned by the water pipe after the split bolts are installed, and finally the cleaning ports are blocked. The inner formwork and the outer formwork are fixed through the split bolts, so that the space between the inner formwork and the outer formwork can meet the design requirements while the side pressure and other loads of concrete are borne, and a certain supporting effect is achieved.
Furthermore, a plurality of secondary ridges arranged along the vertical direction are respectively arranged on one sides of the inner template and the outer template far away from the wall insulation board 20, the distance between every two adjacent secondary ridges is preferably 120mm, and the position where each secondary ridge is placed is preferably that the anchoring piece 10 is pressed; a plurality of main ridges are arranged at intervals along the horizontal direction, the main ridges are arranged in pairs and supported on the anchoring piece 10, and a supporting structure formed by the main ridges and the secondary ridges is fixed. Wherein main stupefied for the steel pipe of following the horizontal direction installation, inferior stupefied for the square timber strip of following the vertical direction installation, the straightness that hangs down of main stupefied and inferior stupefied is adjusted simultaneously to further consolidate inner formword and exterior sheathing, go on smoothly in order to guarantee follow-up pouring operation.
In order to facilitate construction and improve the construction progress, the shear wall parts of the same structures of different floors of the same building can adopt the secondary corrugated frameworks which are repeatedly used for many times so as to integrally reinforce the external part of the wall heat-insulation board 20. The size and the shape of the framework are determined according to the applicable wall. The waste bamboo plywood with the reasonable strength and flatness is transversely connected on the vertical secondary edges at the upper and lower intervals of 300-400 mm and the width of 300mm to manufacture and form.

In the vibration process, the vibrating rod is prohibited to directly vibrate the wall insulation board 20, so that the wall insulation board 20 is prevented from being damaged and the bonding force is not influenced. The surface of the wall insulation board 20 is wrapped by polymer anti-crack mortar and glass fiber mesh cloth, the outer surface can bear 10J impact force, the inner surface is thinner, the impact resistance force is about 3J, but the vibration force of the concrete vibrating rod can reach 4000N when being the highest, and therefore, the wall insulation board 20 is forbidden to be directly vibrated when concrete is poured. The vibrating distance of the vibrating rod is about 40cm, and the vibrating rod should vibrate at least 10cm away from the wall heat-insulating board 20 to ensure the degree of compactness of vibration. When pouring vibration, the wall insulation board 20 is observed, and reinforcement treatment is carried out in time when the leakage of the slurry from the die is found.
