Although the structure of such filler walls is convenient for construction, it has the problem of poor heat preservation and sound insulation effect. In order to improve the heat preservation effect of the building, composite insulation strip boards are often used to replace various blocks, and the existing composite insulation strip boards often use polystyrene boards, polyurethane boards or rock wool boards bonded on one side of the aerated concrete board, which significantly improves the heat preservation and sound insulation effect of the filler wall.

[0021] The core of the utility model is to provide a sandwich composite insulation strip board, which is prefabricated in the factory and sandwiched between two layers of concrete slabs. It has high strength, good protection effect, and reduces the risk of the insulation board falling off.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Description of the drawings: In the following specific embodiments, the descriptions of up, down, left, and right are all with respect to the drawings in the specification and cannot be understood as limitations on the present invention.

[0023] Example 1

[0024] like Figure 1 As shown, a sandwich composite insulation strip comprises an autoclaved aerated concrete panel (1), an inner insulation panel (2), and an autoclaved aerated concrete panel (3), all bonded together from the inside out using an adhesive. The adhesive is specifically polyurethane foam, which exhibits excellent bonding and aging resistance. It also includes anchors (4), which pass vertically through the inner insulation panel (2) and are secured at both ends between the autoclaved aerated concrete panel (1) and the autoclaved aerated concrete panel (2). Multiple anchors (4) are regularly spaced along the panel surface, proportional to the panel width.

[0025] By using two relatively high-strength autoclaved aerated concrete boards to sandwich the inner insulation board 2, the strength of the composite insulation board can be increased and the difficulty of on-site construction can be reduced; by adding multiple tie members 4 between the two autoclaved aerated concrete boards, auxiliary adhesives are used to increase the connection strength between the boards, thereby preventing the outer board from falling off.

[0026] In a specific implementation of this embodiment, the inner insulation board 2 is specifically made of molded polystyrene board, graphite polystyrene board, extruded polystyrene board or graphite extruded board.

[0027] A better flame retardant effect can be achieved by using B1 grade boards. The reason for this is that the use of autoclaved aerated concrete boards in a sandwich arrangement reduces the risk of the inner insulation board 2 coming into contact with a fire source.

[0028] In a specific implementation of this embodiment, Figure 1As shown in the drawings, the thickness of the autoclaved aerated concrete board one 1 and the autoclaved aerated concrete board two 3 is greater than 80mm, and the total thickness of the sandwich type composite thermal insulation strip board is 200-450mm.

[0029] In a specific embodiment of the present embodiment, as shown in the drawings, Figure 1 The sandwich type composite thermal insulation strip board further comprises steel wire meshes 5, and two groups of the steel wire meshes 5 are respectively embedded in the autoclaved aerated concrete board one 1 and the autoclaved aerated concrete board two 3, the steel wire meshes 5 are arranged in parallel with the board surface, and the two ends of the tie member 4 are connected to the steel wire meshes 5.

[0030] Specifically, as shown in the drawings, Figure 1 The tie member 4 specifically adopts a plastic or steel-plastic composite heat-insulating bridge tension structure. The middle section of the bridge tie member 4 is a screw rod, which can adaptively adjust the tension interval, and the through diameter of the screw rod part is not less than 12mm. The two ends of the bridge tie member 4 adopt steel or plastic anchors, which can clamp and fix the steel wire meshes 5.

[0031] Obviously, the steel wire meshes 5 in the present application can also be replaced by steel reinforcement frameworks, and the two ends of the tie member 4 need to be connected to the steel reinforcement frameworks, and similar simple replacement methods all fall within the protection scope of the present application.

[0032] In a specific embodiment of the present embodiment, as shown in the drawings, Figure 1 The side wall of the autoclaved aerated concrete board one 1 and the autoclaved aerated concrete board two 3 is provided with a through groove 6. The autoclaved aerated concrete board one 1 and the autoclaved aerated concrete board two 3 are provided with a through protrusion 7 on the other side wall opposite to the groove 6. The cross-sectional profiles of the groove 6 and the protrusion 7 are matched, that is, when the adjacent two sandwich type composite thermal insulation strip boards are combined, the protrusion 7 can be inserted into the groove 6 to form a mortise and tenon structure.

[0033] By arranging the groove 6 and the protrusion 7 on the side walls of the autoclaved aerated concrete board one 1 and the autoclaved aerated concrete board two 3 respectively, the connection strength between the adjacent two sandwich type composite thermal insulation strip boards is improved.

[0034] Embodiment 2

[0035] An important performance of the composite thermal insulation board used as a filler wall is waterproof performance. There is a joint between adjacent composite thermal insulation boards, and if the outer mortar and decorative surface layer are damaged, rainwater can easily enter the joint, causing water seepage. Water erosion of the adhesive layer can also reduce the bonding strength, and in severe cases, can cause local shedding. Therefore, on the basis of the above-mentioned embodiment 1, the applicant improves the waterproof performance of the sandwich type composite thermal insulation strip board to form the present embodiment.

[0036] like Figure 2 As shown, the sandwich-type composite insulation strip of the present invention further includes an external waterproofing strip 8. A continuous sealing groove is provided on the outside of the protrusion 7, and the external waterproofing strip 8 fills the sealing groove. The outer wall of the external waterproofing strip 8 protrudes from the sealing groove. That is, when adjacent sandwich-type composite insulation strips are spliced ​​together, the external waterproofing strip 8 is compressed by the two side walls, forming a seal to prevent rainwater from further infiltration.

[0037] In a specific implementation of this embodiment, Figure 2 As shown, the sandwich-type composite insulation strip of the present invention also includes an inner waterproof sheet 9. A full-length sealing sheet groove is defined on the side of the inner insulation board 2 near the protrusion 7. The sealing sheet groove extends to the side walls of the autoclaved aerated concrete board 1 and the autoclaved aerated concrete board 2 3. The sealing sheet groove and the protrusion 7 do not interfere with each other. The inner waterproof sheet 9 is filled in the sealing sheet groove, and the outer wall of the inner waterproof sheet 9 protrudes from the sealing sheet groove. That is, when adjacent sandwich-type composite insulation strips are spliced ​​together, the inner waterproof sheet 9 is pressed against the two side walls, forming a secondary seal on the inside, preventing rainwater from further penetrating into the adhesive layer and affecting the adhesive strength.

[0038] By setting up the outer waterproof strip 8 and the inner waterproof board 9 and adopting a secondary double sealing method, the joints of adjacent sandwich composite insulation strips can be waterproofed, thereby avoiding the erosion of the adhesive layer by rainwater and improving the service life of the composite insulation board.

[0039] Specifically, the outer waterproof rubber strip 8 and the inner waterproof plate 9 are both made of rubber material with good weather resistance, that is, EPDM rubber or butyl rubber material.

[0040] It should be noted that the outer waterproof rubber strip 8 and the inner waterproof board 9 can be installed during the prefabrication process in the factory, or can be installed on site.

[0041] In summary, the sandwich composite insulation strip of the present invention can increase the strength of the composite insulation board and reduce the difficulty of on-site construction by using two relatively high-strength autoclaved aerated concrete boards to sandwich the inner insulation board 2. By adding multiple tie pieces 4 between the two autoclaved aerated concrete boards, the auxiliary adhesive increases the connection strength between the boards and avoids the outer board from falling off. In addition, a better flame retardant effect can be achieved by using B1 grade board materials. The reason is that the use of autoclaved aerated concrete board sandwiching method reduces the risk of the inner insulation board 2 contacting the fire source. By respectively providing grooves 6 and protrusions 7 on the side walls of autoclaved aerated concrete board 1 and autoclaved aerated concrete board 2 3, the connection strength between the two adjacent sandwich composite insulation strips is improved. By providing an external waterproof strip 8 and an internal waterproof board 9, a secondary double sealing method is adopted, which can waterproof the joints of the adjacent sandwich composite insulation strips, avoid rainwater erosion of the adhesive layer, and increase the service life of the composite insulation board.

[0042] The above-described embodiments are merely preferred modes of the present application, and are not intended to limit the scope of the present application. Various modifications and improvements to the technical solutions of the present application made by those of ordinary skill in the art without departing from the design spirit of the present application shall fall within the protection scope of the present application as defined by the claims.
