[0037] The connecting member 3 includes a sleeve rod 31 inserted into the insulation board 1, and the outer surface of the sleeve rod 31 is slidably connected to two sleeves 32 and two No. 1 clips 33, one end of the sleeve 32 is fixedly connected to the No. 2 clip 34, the outer surface of the sleeve rod 31 is threadedly connected to two locking nuts 35, and both ends of the sleeve rod 31 are threadedly connected to external screws 36.

[0038] Furthermore, the outer surface of the insulation board 1 is provided with a plurality of equally spaced perforations, into which sleeve rods 31 are inserted, and the first clip 33 and the second clip 34 are closely attached to the steel mesh 2. The advantage is that by arranging a steel mesh 2 at the front and back of an insulation board 1, and then aligning the sleeve 32 with the perforations on the insulation board 1, and then passing the sleeve rod 31 through the first clip 33, the second clip 34, the sleeve 32 and the perforations of the insulation board 1 in sequence, and then connecting the sleeve rod 31 with a locking nut, the insulation board 1 and the steel mesh 2 can be connected, and the steel mesh 2 and the insulation board 1 can be kept at a certain gap due to the arrangement of the first clip 33 and the second clip 34 in cooperation with the sleeve 32.

[0039] Furthermore, the steel mesh 2 is composed of a plurality of horizontally and vertically intersecting steel wires arranged at equal intervals, the diameter of the steel wire is 5-10 mm, and the mesh size of the steel mesh 2 is 20×20 cm. The advantage is that the steel mesh 2 is welded with high-strength steel wires, and by arranging a steel mesh 2 on each side of the insulation board 1, after the entire insulation wall is formed, the steel mesh 2 is inside the insulation wall, which can increase the structural strength of the insulation wall.

[0040] Furthermore, the spacing between the connectors 3 is 50 cm, and the outer surface of the outer wall panel 5 is penetrated with a plurality of circular holes arranged at equal intervals, and the external screws 36 are inserted into the circular holes. The advantage is that when the insulation board 1 and the wire mesh 2 are connected, the circular holes on the outer wall panel 5 are aligned with the sleeve rod 31, and then the external screws 36 are passed through the circular holes of the outer wall panel 5 and threadedly connected with the sleeve rod 31, so that the insulation board 1, the wire mesh 2 and the outer wall panel 5 can be connected to form a complete set of insulation wall panels, and by setting a plurality of connectors 3 for reinforcing and connecting the insulation wall panels, they can be connected as a whole after pouring concrete inside, which increases the structural strength, and before pouring concrete, the weight of the entire insulation wall panel is light, which is convenient for transportation, and the entire insulation wall panel can be lifted by hooking the two sleeves 32 at the top by the hook of the lifting equipment.

[0041] Furthermore, the outer surface of the thickness-fixing pad 4 is provided with four through grooves 41 around its axial direction, and the outer surface of the thickness-fixing pad 4 is integrally formed with four triangular reinforcing plates 42 around its axial direction, one end of the thickness-fixing pad 4 contacts the thermal insulation wallboard 1, and the other end of the thickness-fixing pad 4 contacts the exterior wallboard 5. The advantage is that before connecting the exterior wallboard 5, a number of thickness-fixing pads 4 need to be inserted into the steel mesh 2, and the four through grooves 41 are used to pass the intersecting steel wires, so that the thickness-fixing pad 4 is set so that one end contacts the thermal insulation board 1 and the other end contacts the exterior wallboard 5, so that the distance between the thermal insulation board 1 and the exterior wallboard 5 can be limited, and the height of the thickness-fixing pad 4 can be customized according to the requirements of the project for the wall thickness.

[0042] Furthermore, the top of the steel mesh 2 extends 50 cm beyond the top of the insulation board 1, and the two steel meshes 2, the two exterior wall panels 5 and the insulation board 1 are horizontally offset by 50 cm. The advantage is that when the insulation wall panel is hoisted to the construction site by a crane, after the two insulation wall panels are horizontally connected, there will be parts that intersect each other at the connection, so that after pouring concrete between the insulation board 1 and the exterior wall panel 5, the exterior wall panel 5 does not need to be removed after the concrete is dried, which saves time and effort while the two insulation wall panels can be firmly connected by the concrete interlayer, which is more conducive to the integration of the building wall.

[0043] Furthermore, a groove 101 is provided on one side of the insulation board 1, and a protrusion 102 is integrally connected to the other side of the insulation board 1. The advantage is that when two insulation boards 1 are butt-jointed, the groove of one insulation board 1 can be embedded in the protrusion 102 of the other insulation board 1, which is conducive to connecting the two connected insulation boards 1 into a whole without generating a linear gap.

[0044] The present invention also provides an assembly method of an assembled building insulation wall, which is carried out according to the following steps:

[0045] Step 1: Select high-quality polystyrene particles and graphite powder as raw materials, mix the polystyrene particles and graphite powder in a ratio of 2:1 and then put them into a board making machine, and form an insulation board 1 after high temperature and high pressure treatment;

[0046] Step 2: Take 30-40 parts of cement, 25-30 parts of water, 15-20 parts of foam particles and 0.15-0.2 parts of modified water reducing agent by weight, put them into a mixing device and stir them evenly, lay a layer of glass fiber cloth on the bottom of the mold of the exterior wall panel 5, pour the mixed raw materials, and then cover the surface with a layer of glass fiber cloth, and demould after natural drying to form the exterior wall panel 5;

[0047] Step 3: clamp the thickness-setting pads 4 on the outer surface of the wire mesh 2 and arrange multiple pads at intervals of 1 m;

[0048] Step 4: Place a steel mesh 2 on the front and back of an insulation board 1, with the insulation board 1 and the steel mesh 2 horizontally offset by 50 cm. Then align the sleeve 32 with the perforation of the insulation board 1, and fit the No. 1 clip 33 and the No. 2 clip 34 to the front and back of the steel mesh 2 respectively. Pass the No. 1 sleeve rod 31 through the No. 1 clip 33, the No. 2 clip 34, the sleeve 32 and the perforation of the insulation board 1 in sequence, and then use the locking nut 35 to tighten, so as to complete the connection between the insulation board 1 and the steel mesh 2.

[0049] Step 5: align the multiple circular holes on the outer surface of the exterior wall panel 5 with the multiple sleeve rods 31, and then use the external screws 36 to connect the sleeve rods 31 to form a prefabricated thermal insulation wall panel;

[0050] Step 6: hoist the prefabricated insulation wall panels at the construction site, pour concrete into the gap between the exterior wall panel 5 and the insulation panel 1, and form an insulation wall after drying.

[0051] Furthermore, step one also includes spraying a high-density sound insulation coating on the outer surface of the insulation board 1 after the insulation board 1 is cooled and formed. The advantage is that the insulation board 1 made by mixing polystyrene particles and graphite powder not only has a good insulation effect, but also the addition of graphite powder improves the fire resistance of the insulation board. The exterior wall board 5 made by mixing cement, water, foam particles and modified water reducer, combined with the use of glass fiber cloth, not only makes the exterior wall board 5 have a certain strength but also has good fire resistance. A layer of high-density sound insulation coating is added to the outer surface of the insulation board 1, which further enhances the sound insulation performance of the wall and improves the living comfort.

[0052] Furthermore, the formula of the modified water-reducing agent is calculated as follows in percentage: 10% high-efficiency water-reducing agent, 5% ethylene glycol, 3% propylene glycol, 2% polyacrylate, 0.5% surfactant, and 79.5% water. The advantage is that the addition of ethylene glycol and propylene glycol to the modified water-reducing agent can reduce the freezing point concentration in cement, thereby improving the frost resistance of the exterior wallboard 5, which can effectively prevent cracking and peeling caused by freeze-thaw cycles. At the same time, ethylene glycol and propylene glycol, as non-ionic surfactants, can form a more stable adsorption layer with cement particles, thereby enhancing its dispersibility, which makes the cement particles more evenly distributed during the molding process of the exterior wallboard 5, thereby improving the strength of the exterior wallboard 5.
