[0001] The present application relates to the technical field of thermal insulation wall construction, in particular to a thermal insulation board and a construction method thereof. BACKGROUND

[0002] Whether a house is warm depends largely on the thermal insulation of the thermal insulation wall. At present, the construction of the thermal insulation wall adopts prefabricated thermal insulation units, which are connected with each other to form a thermal insulation board. Concrete is poured between the structural wall and the thermal insulation board to form a thermal insulation wall. In the above process, the pouring pressure and the impact force of the vibration may cause the thermal insulation units of part of the thermal insulation board to be unstable and dislocated, so that the concrete leaks from the dislocation part, the thermal insulation continuity is damaged, and the thermal insulation performance is reduced.

[0003] In the related art, a support body is constructed on both sides of the thermal insulation board. The two support bodies are connected to the two sides of the thermal insulation board through anchor pieces. Then, concrete is poured between the thermal insulation board and the support body to improve the stability of the whole thermal insulation board. However, such a design may cause the thermal insulation wall to be too thick, occupy more space, and affect the appearance. In addition, the installation of a large number of anchor pieces makes the construction complicated. SUMMARY

[0028] By adopting the technical scheme, the stability of the assembly of the thermal insulation units is improved by the reinforcing ribs to constrain the disengagement of the clamping part of the thermal insulation unit from the clamping groove of the adjacent thermal insulation unit, and the lateral pressure borne by the single thermal insulation unit can be shared when pouring concrete, so that it is not necessary to connect each thermal insulation unit with the structure wall through the anchor, thereby reducing the quantity of the anchor and simplifying the construction process. In addition, the end of the anchor away from the target wall is simultaneously pressed and connected with the adjacent two thermal insulation units, so that the stable connection of the thermal insulation board and the structure wall is ensured, and the quantity of the anchor is further reduced.

[0062] Embodiments of the present application are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as a limitation of the present application.

[0063] The following refers to Figures 1-8 A thermal insulation board and a construction method of a thermal insulation board according to embodiments of the present application are described below.

[0064] AsFigures 1-7 As shown, the thermal insulation board comprises a plurality of thermal insulation units 100, a plurality of thermal insulation layers 200 and a plurality of reinforcing ribs 300.

[0065] The thermal insulation unit 100 is a panel unit of the minimum composition of the thermal insulation board. The thermal insulation unit 100 can be selected as a long strip block structure. The thermal insulation unit 100 should have thermal insulation capacity. The thermal insulation unit 100 can be selected as a graphite polystyrene thermal insulation board.

[0066] As shown in Figure 1 and Figure 2 Each thermal insulation unit 100 has at least one side with a clamping portion 110. A clamping groove 120 is formed between the clamping portion 110 and the thermal insulation unit 100. The clamping portion 110 of the thermal insulation unit 100 cooperates with the clamping groove 120 of the adjacent other thermal insulation unit 100.

[0067] In this embodiment, at least one side of any thermal insulation unit 100 has a clamping portion 110. The clamping portion 110 of the thermal insulation unit 100 can have one, two, three or four.

[0068] For example, the thermal insulation unit 100 can have two clamping portions 110. The two clamping portions 110 can be on opposite sides of the thermal insulation unit 100. The orientations of the clamping grooves 120 between the two clamping portions 110 and the thermal insulation unit 100 can be the same or opposite.

[0069] In this embodiment, the clamping portion 110 of the thermal insulation unit 100 is spliced with the clamping groove 120 of the adjacent other thermal insulation unit 100 to the left and right, so as to lengthen the length of the single thermal insulation unit 100.

[0070] According to actual needs, it is also allowed to splice the thermal insulation unit 100 with one clamping portion 110 and the thermal insulation unit 100 with two clamping portions 110.

[0071] For another example, the thermal insulation unit 100 can have two clamping portions 110. The two clamping portions 110 can be on adjacent sides of the thermal insulation unit 100. The orientations of the clamping grooves 120 between the two clamping portions 110 and the thermal insulation unit 100 can be the same or opposite (not shown).

[0072] In this embodiment, four thermal insulation units 100 can be selected. The clamping portion 110 of any thermal insulation unit 100 is spliced with the clamping groove 120 of the adjacent other thermal insulation unit 100, so as to lengthen the length and width of the single thermal insulation unit 100.

[0073] Based on the same inventive concept, the heat preservation unit 100 with three clamping portions 110 or the heat preservation unit 100 with four clamping portions 110 is selected, and when the heat preservation units 100 are spliced with each other, the length and the width of the single heat preservation unit 100 can be simultaneously extended (not shown).

[0074] As shown in Figure 1 , the heat insulation layer 200 is arranged in the heat preservation unit 100, and in actual implementation, the side surface of the heat preservation unit 100 can be first provided with a containing groove, the heat insulation layer 200 is then inserted into the containing groove, and finally, the foamed polyurethane is filled between the containing groove and the heat insulation layer 200. The above process can be performed in construction and can flexibly adjust the required types of the heat insulation layer 200.

[0075] For example, the heat insulation layer 200 can adopt a vacuum heat insulation plate with low thermal conductivity and good heat preservation performance, so as to reduce the thickness of the heat preservation unit 100 while having good heat preservation performance, and also make the heat preservation unit 100 have good fireproof performance.

[0076] When the heat insulation layer 200 is a vacuum heat insulation plate, the vacuum heat insulation plate is in the wrapping of the heat preservation unit 100, so as to avoid damage to the vacuum heat insulation plate in construction, thereby reducing the damage rate of the vacuum heat insulation plate.

[0077] As shown in Figure 1 and Figure 2 , the reinforcing rib 300 is arranged in the heat preservation unit 100, so as to constrain the clamping portion 110 of the heat preservation unit 100 from being separated from the clamping groove 120 of the adjacent another heat preservation unit 100.

[0078] In the embodiment, the reinforcing rib 300 constrains the clamping portion 110 of the heat preservation unit 100 from being separated from the clamping groove 120 of the adjacent another heat preservation unit 100, which can improve the stability of the overall splicing of the heat preservation plate and also improve the strength and rigidity of the overall heat preservation plate.

[0079] The reinforcing rib 300 can be at least one of the following structural forms:

[0080] As shown in Figure 1 and Figure 2 , the clamping portion 110 of each heat preservation unit 100 is provided with a clamping port 111, and the reinforcing rib 300 has a first positioning portion 310 protruding from the bottom wall of the clamping groove 120 and being clamped with the clamping groove 120 of the adjacent another heat preservation unit 100.

[0081] In the embodiment, as shown in Figure 2 , the first positioning portion 310 can enter the clamping port 111 in the second direction and be clamped with the clamping port 111, as shown in Figure 5As shown, the first positioning portion 310 can enter the clamping interface 111 along the first direction and be clamped with the clamping interface 111.

[0082] In this way, on the one hand, the first positioning portion 310 of the reinforcing rib 300 of one thermal insulation unit 100 can generate a constraint force on the clamping interface 111 of the adjacent other thermal insulation unit 100 moving in the second direction opposite direction, thereby improving the stability of the overall splicing of the thermal insulation board. On the other hand, the reinforcing rib 300 can also improve the strength and rigidity of the overall thermal insulation board.

[0083] Secondly, the side wall of one thermal insulation unit 100 is provided with a limiting slot, the arrangement direction of the limiting slot is parallel to the arrangement direction of the clamping slot 120, and the reinforcing rib 300 is arranged on the side wall of the adjacent other thermal insulation unit 100 on the other opposite side and is used for clamping insertion with the limiting slot (not shown).

[0084] In this embodiment, since the reinforcing rib 300 is arranged on the side wall of the thermal insulation unit 100, the reinforcing rib 300 has limited improvement on the strength and rigidity of the thermal insulation unit 100.

[0085] According to the thermal insulation board provided in the embodiments of the present application, by splicing the clamping portion 110 of the thermal insulation unit 100 with the clamping slot 120 of the adjacent other thermal insulation unit 100, the length or width of the single thermal insulation unit 100 can be increased, the heat insulation layer 200 is arranged in the thermal insulation unit 100, so that the thickness of the thermal insulation unit 100 can be reduced while the thermal insulation performance is good, and the clamping portion 110 of the thermal insulation unit 100 is constrained by the reinforcing rib 300 from being separated from the clamping slot 120 of the adjacent other thermal insulation unit 100, which can improve the stability of the overall splicing of the thermal insulation board 100 and also improve the strength and rigidity of the overall thermal insulation board 100.

[0086] In some embodiments, as shown in FIG. 1, Figure 2 As shown, the caliber of the clamping interface 111 decreases in the direction close to the reinforcing rib 300, and the clamping interface 111 penetrates through the opposite two sides of the thermal insulation unit 100.

[0087] In this embodiment, the constraint force of the first positioning portion 310 on the clamping interface 111 moving in the second direction opposite direction can be further improved, and the stability of the overall splicing of the thermal insulation board can be improved.

[0088] In actual implementation, the caliber of the clamping interface 111 can be uniformly reduced in the direction close to the reinforcing rib 300, or the caliber part of the clamping interface 111 can be reduced in the direction close to the reinforcing rib 300, and the present embodiment is not limited.

[0089] In some embodiments, as shown in FIG. 1, Figure 3As shown, the reinforcing rib 300 also has a plurality of second positioning portions 320, the first positioning portions 310 and the plurality of second positioning portions 320 are evenly spaced around the periphery of the reinforcing rib 300.

[0090] In the embodiment, by arranging the plurality of second positioning portions 320 around the side wall of the reinforcing rib 300, on the one hand, the overall strength and rigidity of the insulation board can be further improved, and on the other hand, the reinforcing rib 300 can be easily inserted into the insulation unit 100 and ensured to be stable.

[0091] In actual implementation, the number of the second positioning portions 320 can be three or other numbers, and the structure, size and shape of the second positioning portions 320 are not limited in the embodiment.

[0092] In some embodiments, as shown, Figures 4-6 As shown, at least one side of the insulation unit 100 includes opposite two sides of the insulation unit 100, and the reinforcing rib 300 penetrates at least two adjacent insulation units 100 along the first direction, and the first direction is perpendicular to the other opposite two sides of the insulation unit 100.

[0093] In the embodiment, by penetrating the reinforcing rib 300 through at least two adjacent insulation units 100, the first positioning portion 310 of the reinforcing rib 300 simultaneously generates a constraint force on the clamping port 111 of the insulation unit 100 along the first direction, and the constraint force prevents the insulation unit 100 from moving in the opposite direction along the second direction.

[0094] It can be understood that by limiting at least one side of the insulation unit 100 to the opposite two sides of the insulation unit 100, the cost of a single insulation unit 100 can be saved, and the splicing of multiple insulation units 100 is also facilitated.

[0095] For example, a plurality of insulation units 100 of a first part can be transversely spliced, and a plurality of insulation units 100 of a second part can be transversely spliced, and the plurality of insulation units 100 of the two parts generate a constraint force in the transverse direction through the cooperation of the clamping portion 110 and the clamping groove 120; then, the plurality of insulation units 100 of the two parts are stacked longitudinally, and the reinforcing rib 300 penetrates the insulation units 100 in the longitudinal direction, and generates a constraint force in the longitudinal direction, so that the cost of arranging the clamping portion 110 in the longitudinal direction of the insulation unit 100 is saved.

[0096] It should be noted that the longitudinal direction is perpendicular to the transverse direction, and the longitudinal direction is the same as or opposite to the first direction.

[0097] In actual implementation, the two ends of the reinforcing rib 300 can penetrate a plurality of insulation units 100 along the first direction, and the two ends of the reinforcing rib 300 can be threadedly connected to nuts, and the plurality of insulation units 100 are fastened by the nuts (not shown).

[0098] In some embodiments, as shown, Figure 7As shown, each thermal insulation unit 100 has a through hole a for the anchoring member 400 to pass through, which is used to connect with the structural wall.

[0099] In this embodiment, when the thermal insulation board is used in wall construction, the anchoring member 400 can be used to selectively connect the single thermal insulation unit 100 with the structural wall.

[0100] In some examples, the through hole a is arranged at the joint of the two adjacent thermal insulation units 100, and is used to press the end of the anchoring member 400 away from the structural wall to the two adjacent thermal insulation units 100, respectively.

[0101] In this example, by limiting the position of the through hole a to the joint of the two thermal insulation units 100, the end of the anchoring member 400 away from the structural wall can press the two adjacent thermal insulation units 100 at the same time, thereby ensuring the stable connection of the thermal insulation board with the structural wall while reducing the amount of anchoring member 400.

[0102] As shown in Figure 8 and Figure 9 The present application also provides a construction method of the thermal insulation board.

[0103] The construction method of the thermal insulation board comprises steps 710, 720, 730, 740 and 750.

[0104] Step 710, a plurality of prefabricated thermal insulation units 100 are spliced to form a thermal insulation board.

[0105] In this step, a plurality of suitable thermal insulation units 100 can be selected, and a first part of the plurality of thermal insulation units 100 is spliced horizontally, and then a second part of the plurality of thermal insulation units 100 is spliced horizontally, and then the two parts of the plurality of thermal insulation units 100 are stacked longitudinally, and the first positioning part 310 of the reinforcing rib 300 is clamped with the clamping interface 111 of the longitudinally arranged thermal insulation unit 100 to splice and form a thermal insulation board.

[0106] Step 720, a steel frame is bound on the side of the target wall 500.

[0107] In this step, the target wall 500 is selected, and the base steel bars are pre-buried at the position of the target wall 500, the vertical steel bars are vertically fixed on the base steel bars, the horizontal steel bars are fixed in the horizontal direction at different positions of the vertical steel bars, and the steel frame is bound.

[0108] Step 730, the thermal insulation board is placed on the side of the steel frame away from the target wall 500, and a pouring area is formed between the thermal insulation board and the target wall 500.

[0109] Step 740, the anchor 400 is selectively passed through the through hole a of any thermal insulation unit 100, and the end of the anchor 400 away from the target wall 500 is crimped to the adjacent two thermal insulation units 100, and the plurality of anchors 400 are connected to the steel reinforcement frame near the end of the target wall 500.

[0110] In this step, by crimping the end of the anchor 400 away from the target wall 500 to the adjacent two thermal insulation units 100, the stability of the thermal insulation plate and the structure wall is ensured, and the amount of anchor 400 is reduced.

[0111] The anchor 400 can be an anchor rod, and the end of the anchor 400 away from the thermal insulation unit 100 can be tied with the steel reinforcement frame, and the number of anchors 400 per square meter can be greater than or equal to 6.

[0112] Step 750, pouring concrete in the pouring area to form a structure wall.

[0113] In this step, when pouring concrete in the pouring area, a vibrating rod can also be used to vibrate the concrete to make it dense.

[0114] The effective length of the end of the anchor 400 away from the thermal insulation unit 100 into the structure wall is not less than 100mm.

[0115] In the related art, a large number of anchors 400 are used to connect each thermal insulation unit 100 on the side of the thermal insulation plate close to the target wall 500, and then concrete is poured between the thermal insulation plate and the target wall 500 to ensure the stability of each thermal insulation unit 100 and avoid the thermal insulation unit 100 being unstable and misaligned during concrete pouring, resulting in the destruction of thermal insulation continuity, the reduction of thermal insulation performance, and the simplification of pre-embedded anchor 400 installation construction.

[0116] In the above embodiments of the present application, by making the first positioning part 310 of the reinforcing rib 300 and the clamping interface 111 of the longitudinally arranged thermal insulation unit 100 clamped, the stability of the thermal insulation unit 100 splicing can be improved, and the lateral pressure borne by the single thermal insulation unit 100 can be shared during concrete pouring, so that each thermal insulation unit 100 does not need to be connected to the structure wall by the anchor 400, thereby reducing the amount of anchor 400 and simplifying the construction process.

[0117] In addition, the end of the anchor 400 away from the target wall 500 is crimped to the adjacent two thermal insulation units 100, thereby ensuring the stability of the thermal insulation plate and the structure wall, and further reducing the amount of anchor 400.

[0118] According to the construction method of the insulation board provided in the embodiment, the clamping part 110 of the insulation unit 100 is constrained by the reinforcing rib 300 to prevent the clamping part 110 from being separated from the clamping groove 120 of the adjacent insulation unit 100, so that the stability of the overall splicing of the insulation board is improved. The end of the anchoring piece 400 away from the target wall 500 is pressed against the adjacent two insulation units 100, so that the stability of the connection between the insulation board and the structural wall is ensured, the use amount of the anchoring piece 400 is reduced, and the construction process is simplified.

[0119] In some embodiments, step 710 comprises:

[0120] Step 711, prefabricating the insulation unit 100.

[0121] In this step, the expandable graphite polystyrene particles prepared through the pre-expansion, curing, molding, drying and cutting granulation processes are uniformly mixed with the inorganic flame-retardant gel material according to the proportion, pure water is added and stirred uniformly, and then poured into a mold for molding and hardening to prepare the insulation unit 100.

[0122] Step 712, reserving a containing groove in the middle of the insulation unit 100 for the heat insulation layer 200.

[0123] In this step, the heat insulation layer 200 can be inserted into the containing groove from top to bottom after the transverse splicing of the transverse row of insulation units 100.

[0124] In this step, the adhesive can be polyurethane foam adhesive to ensure that the gap between the containing groove and the heat insulation layer 200 is completely filled, so as to increase the adhesion and integrity of the heat insulation layer 200 and the insulation unit 100.

[0125] Step 715, laying the glass fiber mesh on the side of the insulation unit 100 away from the target wall 500, and laying the mortar 600 on one side of the glass fiber mesh.

[0126] It should be noted that the reinforcing rib 300 can be inserted after the longitudinal stacking of a plurality of insulation units 100, and the plurality of insulation units 100 can be determined according to the height of the target wall 500, for example, the plurality of insulation units 100 can be inserted by the reinforcing rib 300 at the height of a floor.

[0127] As shown in Figure 7 and Figure 8 In some embodiments, step 710 comprises:

[0128] Step 711, prefabricating the insulation unit 100.
