Description

TECHNICAL FIELD

[0001] The present application relates to a thermal insulation external wall panel and a building. BACKGROUND

[0002] At present, with the large-scale construction of fabricated buildings, thermal insulation external wall panels have also been widely used. Thermal insulation external wall panels generally include a concrete panel body and a thermal insulation panel built into the concrete panel body or a thermal insulation system attached to the outer surface of the concrete panel body. The former currently has two forms, one of which is to directly cast the thermal insulation panel into the concrete panel body when the thermal insulation external wall panel is made, and the latter is to form a cavity in the concrete panel body when the thermal insulation external wall panel is made, and the concrete panel body has a corresponding injection hole, and then a thermal insulation body is formed in the cavity by, for example, polyurethane foaming.

[0003] For the thermal insulation system attached to the outer surface of the concrete panel body, it mainly includes an interface treatment layer, an adhesive layer, a thermal insulation layer, a protective layer and a crack-resistant layer. The adhesion between the thermal insulation system and the concrete panel body is mainly achieved by the adhesion of the adhesive layer, and the interface treatment layer is mainly used to improve the affinity between the thermal insulation panel and the cement-based adhesive layer. In order to improve the bonding strength between the thermal insulation system and the concrete panel body, a number of anchor bolts are often installed to connect the thermal insulation layer and the concrete panel body. However, due to the influence of gravity, wind load and other factors, the problem of the thermal insulation system falling off the concrete panel body cannot be avoided. It should be noted that this kind of thermal insulation external wall panel is essentially derived from the traditional pasted composite external wall thermal insulation system, and the pasted composite external wall thermal insulation system has been prohibited from use, because the bonding capacity between the pasted composite external wall thermal insulation system and the wall is relatively poor, and it is easy to fall off. News about the peeling of external wall thermal insulation systems frequently appears in newspapers. The thermal insulation system attached to the outer surface of the concrete panel body derived from the pasted composite external wall thermal insulation system has the same structure as the pasted composite external wall thermal insulation system, and its popularization and application are gradually restricted.

[0004] It should be noted that the greater the thickness of the thermal insulation panel in the thermal insulation system, the more likely it is to fall off the concrete panel body. With the further improvement of building thermal insulation requirements, when the same type of thermal insulation panel is used, a greater thickness is often needed to meet the current regulatory thermal insulation requirements, and the relatively greater thickness inevitably makes it more difficult to popularize and apply the thermal insulation system attached to the concrete wall panel.

[0005] Further, a scheme of embedding the thermal insulation board into the concrete wallboard is proposed and is currently applied in a certain range. It should be known that for the fabricated building, a connecting piece is often used to mount the thermal insulation outer wallboard on, for example, a steel structure, and therefore, the weight requirement of the thermal insulation outer wallboard itself is relatively high. In view of this, the current thermal insulation outer wallboard is mainly autoclaved aerated concrete thermal insulation outer wallboard, among which, the ALC (Autoclaved Lightweight Concrete, autoclaved lightweight aerated concrete) outer wallboard is used in the widest range, and the specific gravity of the ALC is less than one fourth of the ordinary concrete, which greatly reduces the self-weight of the thermal insulation outer wallboard. However, for example, the ALC outer wallboard needs to be autoclaved during the manufacturing process, and the autoclaving temperature is usually not less than 170℃, and some can reach 205℃ (the autoclaving temperature of different types of steam pressure concrete is different), and the melting temperature of most thermal insulation boards is lower than the autoclaving temperature of the ALC, and the material selection range is limited. In addition, during the manufacturing process, the thermal insulation board needs to be pre-positioned on the corresponding tooling or cage, and the manufacturing itself is relatively difficult.

[0006] In some implementations, the characteristics of the partial thermal insulation board melting under the autoclaving condition are utilized, so that a cavity is formed in the ALC outer wallboard after the autoclaving is completed, and then the thermal insulation layer is generated in the cavity by, for example, the polyurethane foaming method, but the overall manufacturing process is complex, for example, an injection port for polyurethane foaming needs to be left.

[0007] In addition, the outer wall thermal insulation board in the cavity, for example, the polyurethane foaming, has a large number of return situations, and the main problem is that the heat insulation coefficient does not meet the standard. It is found through inspection that when the thermal insulation layer is made by foaming in a small space, a large number of voids are prone to occur, that is, the cavity filling effect is very poor, and the porosity of some is even more than 60%. SUMMARY

[0008] The purpose of the present application is to provide a thermal insulation outer wallboard with relatively low manufacturing difficulty under the condition of ensuring that the thermal insulation board is not easy to fall off, and the present application also provides a building mainly using the thermal insulation outer wallboard to construct the outer wall.

[0009] According to a first aspect of the embodiment of the present application, a thermal insulation outer wallboard is provided, comprising: a board body, which is a reinforced concrete strip board, and one board surface is provided with a rectangular accommodating groove; a thermal insulation board, which is a rectangular thermal insulation board and is embedded in the rectangular accommodating groove; the rectangular accommodating groove is a fully-enclosed accommodating groove or a semi-enclosed accommodating groove with one groove wall or two groove walls missing.

[0011] Optionally, the distance is 35mm~65mm.

[0012] Optionally, the rectangular accommodating grooves are one or two columns, and the number of each column is 1~6; wherein, the column direction is the length direction of the plate body; The distance between adjacent rectangular accommodating grooves is not less than 20mm.

[0013] Optionally, the outer surface of the insulation board accommodated in the rectangular accommodating groove is coplanar with the plate surface having the rectangular accommodating groove or is 1~3mm lower than the plate surface.

[0014] Optionally, the reinforcing rib of the plate body has 1~3 meshes; The reinforcing rib used by the mesh is a straight rib, or the reinforcing rib used by the mesh located at the side of the rectangular accommodating groove has a bending head at the end or constitutes a groove type mesh plate, wherein the bending direction of the bending head is towards the plate surface of the rectangular accommodating groove, and the vertical wall of the groove type mesh plate extends into the groove wall of the rectangular accommodating groove.

[0015] Optionally, the bending head is located in the concrete outside the rectangular accommodating groove; If the reinforcing rib used by the mesh is a straight rib, the application further comprises a surrounding mesh around the rectangular accommodating groove.

[0016] Optionally, the mesh with the bending head has a longitudinal rib bending head and a transverse rib bending head; Corresponding to the end of the plate body, an end reinforcing rib or an additional mesh for interconnecting the longitudinal rib bending heads at the same end is arranged; Corresponding to the two sides of the plate body, a side reinforcing rib or an additional mesh for interconnecting the transverse rib bending heads at the same side is arranged.

[0017] Optionally, the end reinforcing rib and the side reinforcing rib are interconnected to form a ring rib.

[0023] In embodiments of the present invention, when constructing the insulation layer structure, the provided insulated exterior wall panel first processes rectangular receiving grooves into the reinforced concrete strip, and then embeds the corresponding rectangular insulation board into them, forming a molded interlocking structure, which can be referred to as an inlaid structure. Accordingly, since the insulated exterior wall panel is installed on the building with the panel surface having the rectangular receiving groove as the vertical surface, and the groove wall of the rectangular receiving groove is used to support the insulation board, a reliable connection is achieved by means of this type of surface fit, ensuring that the insulation board is not easily detached from the panel. During manufacturing, for example, a core mold can be used to form the rectangular receiving groove. After the panel is cured or steam-cured, the cut insulation board is embedded into the rectangular receiving groove. The manufacturing process is relatively simple and less affected by the panel manufacturing process. Attached Figure Description

DETAILED DESCRIPTION

[0043] It should be understood that the basic shape of the thermal insulation exterior wall panel is strip-shaped, and the length-width ratio is usually greater than 3, thus having a certain length and width. The length of the thermal insulation exterior wall panel is consistent with the height of the wall in the installed state, and the length direction is also called the longitudinal direction. The width direction is also called the left-right direction, the lateral direction, or the transverse direction.

[0044] The plane determined by the length and the width is the basic plane, and the panel surface of the thermal insulation exterior wall panel is parallel to the basic plane. The distance between the two panel surfaces is the panel thickness of the thermal insulation exterior wall panel.

[0045] It should be noted that in the embodiments of the present application, up, down, left, right, in, out, and the like, as well as similar descriptions, are for the purpose of explanation and interpretation, and do not have specific limitations.

[0046] Likewise, the expressions, for example, vertical, horizontal, or the like, are also used for the purpose of illustration or explanation.

[0047] In addition, spatially relative terms, such as "under", "below", "lower", "over", "upper" and the like, can be used herein for ease of description to describe one element or portion's relationship to another element(s) or portion(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use and / or operation in addition to the orientations depicted in the figures.

[0048] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0049] In addition, as a special note, the technical features involved in the different embodiments of the application described below can be combined with each other as long as there is no conflict.

[0050] It should be understood that in the mechanical field, the normative geometric terms are usually used to describe the approximate mechanical structure, and do not mean that the mechanical mechanism has the geometric features corresponding to the geometric terms in the strict sense. For example, the rectangular plate in the general sense is actually a cuboid plate, and the edges of the plate body are not necessarily neat, for example, with Figure 1 The tenon 1 and the mortise 6 shown in the figure.

[0051] Figure 1 And Figure 2 An example of a thermal insulation external wall panel has a general structure of current thermal insulation external wall panels, which generally includes a plate body 2 and a thermal insulation panel 10 installed on the plate body 2. The thermal insulation external wall panel as a whole is a prefabricated panel. For the traditional application of making a thermal insulation system on the outer surface of the plate body 2, the side with the thermal insulation system is relatively fragile and is easy to be damaged during storage and transportation. However, this does not occur in the implementation of the built-in thermal insulation panel 10. In some embodiments of the application, one side of the thermal insulation panel 10 is exposed, and in some embodiments, such as Figure 16 The example plate body 2 exposes one panel surface and one side surface of the thermal insulation panel 10, and in Figure 17 In the example structure, one panel surface and two side surfaces of the thermal insulation panel 10 are exposed. It should be understood that for the storage and transportation of the thermal insulation external wall panel, the plate bodies 2 are generally stacked for storage and transportation, and the thermal insulation panel 10 is relatively small in pressure bearing, and there is no other relatively fragile functional layer such as a decorative layer, which is also not easy to be damaged.

[0052] The plate body 2 adopts reinforced concrete strip plate, wherein the added reinforcement is generally referred to as strip plate internal force reinforcement. Currently, there are mainly two kinds of strip plate internal force reinforcement, one is steel reinforcement, and the other is FRP (Fiber Reinforced Polymer) reinforcement. The FRP reinforcement is a hard and brittle material without plasticity, and the mesh made of the FRP reinforcement is generally Figure 9 The illustrated mesh formed by longitudinal straight reinforcement and transverse straight reinforcement. The steel reinforcement has relatively good plasticity, and it is relatively easy to make a bend at the end of the transverse reinforcement or the longitudinal reinforcement.

[0053] The FRP reinforcement mainly includes CFRP (Carbon Fibre-reinforced Polymer) reinforcement and AFRP (Aramid Fibre-reinforced Polymer) reinforcement, which are collectively referred to as FRP reinforcement. The typical characteristics of the FRP reinforcement are that the tensile strength is not weaker than that of the building steel reinforcement, and there is no need for corrosion protection, the thermal conductivity is weaker than that of the steel reinforcement, and the market price is relatively low, so the FRP reinforcement has its unique advantages in the field of building.

[0054] In addition, for example, the group standard T / SDCEAS 30009-2023 "Fabricated lightweight concrete composite insulation external wall panel (VPR) system construction" (hereinafter referred to as 30009 standard) directly adopts the FRP reinforcement, and further provides a fiber reinforced reinforcement cage (FRPC, Fiber Reinforced Polymer Cage). The fiber reinforced reinforcement cage is the form of the FRP reinforcement in the concrete external wall panel. Currently, the FRP reinforcement has been widely used in the building industry.

[0055] The reinforced concrete plate has higher strength than the unreinforced concrete plate, and as described above, the insulation external wall panel is a prefabricated plate, which not only has relatively high requirements for its strength under use conditions, but also has strength requirements for its storage, transportation, hoisting and the like. Therefore, the current insulation external wall panel generally adopts a reinforced external wall panel.

[0056] The number of meshes used in insulation external wall panels of different thicknesses varies, but at least one piece, but generally not more than three pieces. The mesh limited by the number here is the same mesh as the traditional insulation external wall panel, that is, the mesh that simply emphasizes the number.

[0057] Due to the slightly poor shear resistance of the FRP reinforcement, a larger number of meshes or auxiliary meshes can also be used in some embodiments. For example, it is relatively difficult to make a bend in the FRP reinforcement, so for the purpose of strengthening the bending resistance of the FRP reinforcement, a larger number of meshes or auxiliary meshes can also be used in some embodiments. Figure 5The mesh in the middle of the groove wall of the mounting groove 11 can be a mesh perpendicular to the plate surface, and is arranged around the mounting groove 11, i.e. is accommodated in the groove wall of the mounting groove 11. The plate surface in which the mounting groove 11 is opened is the outer surface of the thermal insulation external wall panel when it is installed in a building, i.e. the thermal insulation panel is outwardly offset.

[0058] It should be understood that in the art, there are specific technical requirements for the anchoring depth, but in the embodiments of the present application, the main part of the plate body 2, which does not include the mounting groove 11, for example, meets the anchoring depth requirements of the specification. The peripheral edge of the mounting groove 11 is mainly used for positioning and installing the thermal insulation panel 10, and the contribution of the thermal insulation external wall panel strength can be ignored, so a relatively small anchoring depth, for example, not more than 25 mm, can be selected. The main part and the positioning and installing part for positioning and installing the thermal insulation panel 10 are two parts determined in the thickness direction of the thermal insulation external wall panel, the former is referred to as the main part, and the latter is referred to as the positioning and installing part.

[0059] In some embodiments, the reinforcing steel bars for reinforcing the positioning and installing part can be selected to be relatively small in diameter to meet the specification requirements of the anchoring depth. For example, the reinforcing steel bars for reinforcing the main part are selected to be 6 mm in diameter, and the reinforcing steel bars for reinforcing the positioning and installing part are selected to be 1 mm in diameter, which meets the requirement of the anchoring depth of 10D~15D (D is the diameter of the anchoring steel bar). Figure 5 The thickness of the groove wall of the mounting groove 11 is 35 mm, and when the anchoring steel bar is located in the middle of the thickness direction of the groove wall, the requirement of the anchoring depth can still be met.

[0060] In other embodiments, the mesh for reinforcing the positioning and installing part is a steel mesh, for example, a steel mesh with a specification of a hole of 12.7x12.7 mm and a wire diameter of 0.4-0.9 mm. The steel mesh is welded on the mesh for reinforcing the main part in a welding manner, and the steel mesh is perpendicular to the mesh and parallel to the corresponding groove wall of the mounting groove 11.

[0061] Just now, when the steel mesh is used, a bending manner can be used to form a groove type structure as shown in Figure 18 The vertical wall 37 shown in the figure extends into the groove wall of the mounting groove 11, and the bottom wall 38 constitutes a mesh for reinforcing the plate body 2. Although the steel wire used in the steel mesh is relatively thin, the reinforcement of the plate body 2 still meets the requirements due to the relatively high density.

[0062] Similarly, if a perforated plate is used, a structure as shown in Figure 18 can also be made.

[0063] The thermal insulation panel 10 provided by the factory is generally a rectangular panel, and the size of the thermal insulation panel 10 can be customized according to customer requirements, so that the mounting groove 11 can be arranged in the middle of the thermal insulation panel 10 as shown in Figure 5The size of the installation groove 11 is determined, and the corresponding insulation board manufacturer can customize the relevant insulation board 10. For the installation groove 11, the basic shape is rectangular, and it is denoted as a rectangular receiving groove.

[0064] The rectangular receiving groove and the corresponding insulation board 10 are geometrically similar structures, and the sizes of the two can be completely the same. When the geometrically similar structure is used, the space for the adhesive mortar layer between the insulation board 10 and the groove wall is left, so that the insulation board 10 and the rectangular receiving groove can further provide chemical bonding by, for example, adhesive mortar, in addition to the form locking. When the design size of the rectangular receiving groove and the corresponding insulation board 10 is completely the same, the combination between the two can be an interference fit, and the insulation board 10 is pressed in during assembly.

[0065] The adhesive mortar can also be replaced by other adhesives, which is a general understanding in the art for the connection between the insulation board 10 and the board body 2, and will not be described here.

[0066] If the insulation board 10 and the rectangular receiving groove are geometrically similar, the space between the insulation board 10 and the groove wall (including the groove bottom) of the rectangular receiving groove is not less than 2mm and not more than 6.5mm on one side.

[0067] When the insulation board 10 is installed in, for example, the installation groove 11, the interface agent can be sprayed on the five faces or all six faces of the insulation board 10 first, then the adhesive mortar is applied, and then the insulation board 10 is pressed into the installation groove 11. The spraying of the interface agent on all six faces of the insulation board 10 is because the wall construction is completed, and the construction of the leveling layer and the installation of the finish layer are still needed, and the firmness of the combination between the insulation board 10 and the functional layer on its outer side still needs to be considered. Correspondingly, when the insulation board 10 is currently installed into the installation groove 11, only the five faces of the insulation board 10 are sprayed with the interface agent, and the remaining one face is the outer surface of the insulation board 10 in the installed state in the installation groove 11.

[0068] Regarding the bonding strength between the insulation board 10 and the board body 2, due to the use of the inlaid structure, the bonding strength between the insulation board 10 and the board body 2 is relatively high, and even without connecting pieces, the probability of the insulation board 10 falling off can be effectively reduced.

[0069] In a more preferred embodiment, connecting pieces, such as anchor bolts, can be provided between the insulation board 10 and the board body 2. The connection mode of the anchor bolts can be the same as that in the conventional installation mode of the adhesive insulation board 10, and will not be described here. However, based on the above description, it can be known that due to the use of the inlaid structure, the number of anchor bolts can be less than that under the adhesive condition. Figure 15In the illustrated structure, the individual thermal insulation board 10 used is relatively small, and each thermal insulation board can be provided with only one anchor bolt. Accordingly, if the size of the thermal insulation board is relatively large, a larger number of anchor bolts can be fitted to each thermal insulation board.

[0070] In some embodiments, the thermal insulation board 10 can also be prevented from being pulled out of the mounting groove 11 by limiting the position of the thermal insulation board 10, mainly by using a limiting pin. Accordingly, as shown in Figure 11 a hole can be formed in the groove wall, and after the thermal insulation board 10 is installed in place, the pin is driven through the hole to form a limit.

[0071] The use of limiting pins and anchor bolts to strengthen the connection between the thermal insulation board 10 and the board body 2 can also be adopted simultaneously.

[0072] Regarding the number of rectangular receiving grooves, the size of the board body 2 is mainly considered. It is known that in the field, the length of the board body 2 is from 2.5m to 6m, and whether there will be larger or smaller size board body 2 in the future is still possible, for example, the first floor of some specific buildings has a floor height of more than 5m, and with the improvement of living standards, non-standard specific floor height is also increasing. The length of the commercially available thermal insulation board 10 is generally not more than 1200mm, and generally not less than 300mm. If the size of the board body 2 is relatively small, the Figure 5 way with a single mounting groove 11 can be used. If the size of the board body 2 is relatively large, for example Figure 3 In the illustrated case, a pair of mounting grooves 11 is used. If the size of the board body 2 is larger, more mounting grooves 11 are adapted to accommodate commercially available thermal insulation boards 10.

[0073] In addition, as mentioned earlier, in the embodiments of the present application, the focus is on ordering design size thermal insulation boards 10 from thermal insulation board manufacturers, but considering the strength of the thermal insulation board 10 itself, the size of a single thermal insulation board 10 should not be too large, therefore, regarding the number of said rectangular receiving grooves, these factors need to be considered, a plurality of, for example, two columns and multiple rows, can be provided on a board body 2, forming a matrix arrangement, each column has 1-6. Among them, the column direction is the length direction of the board body 2.

[0074] At present, the most commonly used thermal insulation exterior wall board has a length of about 3m, for example, the standard 3m of ordinary residential buildings, at this time the number of mounting grooves 11 can be adapted to be 3, excluding the size of the mounting groove wall, the length of each thermal insulation board 10 can be 900mm.

[0075] Although the length of the board body 2 varies greatly, the width varies little. Under this condition, if there are multiple mounting grooves 11, the main arrangement is single column and multiple rows, and the number of rows is the number of mounting grooves 11. The column direction here is the length direction of the thermal insulation exterior wall board.

[0076] As to the groove depth of the installation groove 11, it is selected according to the standard insulation requirement, for example, the thermal conductivity of the insulation exterior wall panel is required to be not less than a certain value, and a certain type of insulation panel with a predetermined thickness is selected. Currently, the thermal conductivity of the building exterior wall has higher requirements.

[0077] However, the performance of the insulation panel 10 varies relatively greatly. For some insulation panels 10, even a thickness of 20 mm can meet the current insulation requirements, but for other insulation panels 10, a panel thickness of more than 100 mm or even thicker is required to meet the current insulation requirements. Therefore, the size of the groove depth depends on the insulation performance of the insulation panel 10 itself, and under the predetermined insulation requirement, the groove depth is negatively related to the insulation performance of the insulation panel.

[0078] Further, it should be known that with the development of technology, some insulation panels 10 have better insulation performance, and it is foreseeable that relatively thinner insulation panels 10 can be used. Furthermore, the groove depth of the installation groove 11 should not be too large, and under the condition of meeting the standard insulation requirement, the groove depth should not be greater than 120 mm, and the smaller the groove depth, the better. Therefore, it is a better choice to select an insulation panel 10 with better insulation performance, so that the groove depth can be relatively small.

[0079] In some embodiments, under the condition of determining the base groove depth, the processing error and the assembly error need to be considered, and a margin is left to ensure that the outer surface of the insulation panel 10 does not protrude above the installation groove 11. Therefore, under the condition of assembling the insulation panel 10, there is a height difference between the outer surface of the insulation panel 10 and the panel surface of the panel 2 having the installation groove 11, and the height difference is less than 1 mm, and when the error is exceeded, it should not be greater than 3 mm.

[0080] In other embodiments, under the condition that the strength of the aforementioned main part alone meets the strength requirement of the insulation exterior wall panel, the thickness of the positioning and installation part is mainly used to meet the installation of the insulation panel 10, and at this time, the installation groove 11 should be sufficient to contain the corresponding insulation panel 10. At this time, the height difference between the outer surface of the insulation panel 10 and the panel surface having the installation groove 11 can be greater than 1.5 mm, but should not be greater than 5 mm, otherwise it will lead to the overall thickness of the insulation exterior wall panel being too large. In these embodiments, after the insulation panel 10 is installed in the installation groove 11, the installation groove 11 is not completely filled, and the part of the wall formed by the insulation exterior wall panel is called the base wall, and a leveling layer is usually needed outside the base wall, and then a finish layer is made, and the slurry during the making of the leveling layer will further fill into the installation groove 11 to form a connecting body, which is beneficial to the reliable combination of the leveling layer and the finish layer on the base wall.

[0081] The height difference between the outer surface of the insulation board 10 and the surface of the board with the mounting groove 11 is not greater than 10 mm, because the size of the slurry changes after curing, and the size change of the leveling layer with different thicknesses is different, which will affect the production of the finishing layer after the wall surface is leveled.

[0082] The distance between the rectangular receiving groove and the corresponding board edge is not less than 20 mm as a factor considered in terms of strength. Considering the requirement for thermal insulation, the distance can be as small as possible under the condition of meeting the strength requirement, and in a more preferred embodiment, the distance is not greater than 120 mm. For the convenience of description, the part of the board body 2 determined by the distance is referred to as a surrounding wall, and the distance is referred to as the thickness.

[0083] Further, considering the condition of planting a steel bar in the surrounding wall, the surrounding wall needs to have a certain thickness to meet the aforementioned requirement for the depth of the steel bar. At the same time, based on the foregoing description, it can be known that the main part is the main provider of the strength of the thermal insulation external wall board, and therefore there is no high requirement for the depth of the steel bar in the surrounding wall, and therefore, in the preferred embodiment, the steel bar still needs to be planted in the surrounding wall to improve the strength of the surrounding wall under the condition that the depth of the steel bar cannot meet the requirement due to the relatively thin surrounding wall.

[0084] In addition, as described previously, in order to meet the requirement for the steel bar, the steel bar located in the surrounding wall can be selected to be a relatively thinner steel bar or steel wire relative to the diameter of the steel bar used in the main part.

[0085] Correspondingly, if there are multiple rectangular receiving grooves, two adjacent rectangular receiving grooves share a surrounding wall, and the thickness of the surrounding wall is preferably not less than 20 mm as described previously. Similarly, the thickness of the surrounding wall should not be greater than 120 mm.

[0086] According to the thermal insulation external wall board of the embodiment of the present application, as described previously, it includes two or three meshes, and some thermal insulation external wall boards with relatively small thickness specifications only need to be provided with one mesh. The mesh here is consistent with the mesh in the conventional thermal insulation external wall board in the concept of strengthening the board body 2, and in some embodiments, the meshes can all be straight mesh 13. As shown in the mesh, it includes a second longitudinal bar 19 and a second transverse bar 20, and as described previously, the mesh of this form is relatively easy to manufacture whether it is made of a steel bar or an FRP bar, and it is a conventional mesh, which will not be described here. Figure 9 In some embodiments of the thermal insulation external wall board, the mesh used can all be the straight mesh 13 as shown in the figure, and the surrounding wall described previously can be individually strengthened or not strengthened.

[0087] Figure 9

[0088] ​​For ease of explanation, the ribs or mesh that provide individual reinforcement to the enclosure will be referred to as additional mesh in the following text. In some embodiments, the additional mesh may be made into a rectangular circle, while the whole may be referred to as the enclosure mesh.

[0089] Figure 6 The illustrated structure is a double-mesh structure, meaning that an insulated exterior wall panel has two mesh panels: one is a straight-ribbed mesh panel 13, and the other is a bent mesh panel 12. Based on the positional relationship determined by the inner and outer surfaces of the insulated exterior wall panel during installation on a building, the straight-ribbed mesh panel 13 is the inner mesh panel, and the bent mesh panel 12 is the outer mesh panel. The ends of the ribs used in the bent mesh panel 12 have bends, and the bending direction of the bends is towards the outer surface of the panel 2. The bends are located within the enclosure wall. Here, "located within the enclosure wall" indicates that the enclosure wall is reinforced, but does not mean that the entire bend is located within the enclosure wall.

[0090] Considering the rebar installation in the enclosure, a thickness of not less than 35mm is preferred to ensure that the rebar installation depth meets the requirements.

[0091] In some embodiments, the body of the bend is perpendicular to the surface of the insulated exterior wall panel. In other embodiments, the body of the bend is not required to be perpendicular to the surface of the insulated exterior wall panel. Here, the body of the bend refers to, for example, the end of a reinforcing bar excluding the natural curvature produced by the bend.

[0092] When all the mesh panels of an insulated exterior wall panel are made of straight rib mesh 13, in some embodiments, an independent enclosure mesh can be configured for the rectangular receiving groove. The enclosure mesh can be pre-integrated with the outer mesh panel by means of welding, for example, to facilitate the overall positioning and fixing of the mesh cage when the panel 2 is poured.

[0093] When the outer mesh is a bent mesh 12, the bend can be used as the mounting base, and the additional mesh is welded to the bend.

[0094] exist Figure 7 and Figure 8 In the illustrated structure, one embodiment of the elbow mesh 12 is shown, wherein in Figure 8 It can be clearly seen that the end of the first longitudinal rib 15 has a first upper bend 17, and the four first upper bends at the same end are also connected to a first end reinforcing rib 14, which can also be replaced by the additional mesh. Figure 7 In the illustrated structure, the first horizontal rib 16 is a straight rib. It should be noted that even if... Figure 7 In the structure shown, if only the first longitudinal bar 15 is a bent bar, the first upper bend 17 of the first longitudinal bar 15 can also be used as the installation base to set up the mesh panel. Relatively speaking, due to the fewer connection points, the installation shape of the mesh panel is not easy to maintain.

[0095] Thus in a more preferred embodiment, the cross ribs also adopt elbow ribs. Specifically, in Figure 10 and Figure 11 In the exemplified structure, both the third longitudinal rib 22 and the third cross rib 23 adopt elbow ribs, wherein Figure 11 The structure form can be more clearly shown.

[0096] As an optional example, the overall production difficulty of the net cage is relatively large, but it can still be taken as an example.

[0097] In a more preferred embodiment, in order to reduce the overall production difficulty, the reinforcing rib is arranged on the same side or the same end elbow, and the diameter of the reinforcing rib is completely the same as the diameter of the rib used in the net, which is convenient for overall preparation. And from Figure 9 As can be seen from the exemplified structure, the density of the rib used in the net of the thermal insulation external wall panel is not large, and the end or side reinforcing rib can only be arranged at each end or each side. Thus Figure 11 In the exemplified state, there is only one third end reinforcing rib 21 at the corresponding end, and the position of the third end reinforcing rib 21 is in the middle of the mounting groove 11 in the direction of the groove depth of the mounting groove 11. If there is a bias, it is also biased outwardly in the middle of the mounting groove 11, and the bias amount is not greater than one fifth of the mounting groove depth.

[0098] In Figure 12 and Figure 13 In the exemplified structure, there are both end reinforcing ribs and side reinforcing ribs, wherein the end is in the longitudinal direction of the thermal insulation external wall panel, and the side is in the width direction of the thermal insulation external wall panel.

[0099] In Figure 13 In the exemplified structure, the fourth end reinforcing rib 30 and the fourth side reinforcing rib 27 are connected as a whole, thereby forming a ring rib on the whole, so that the integrity of the net is better.

[0100] The above is an exemplified description combined with the drawings of the specification, and is not a limitation on the present application. Under the concept of the present application, the above embodiments or different embodiments can be combined without mutual conflict. Although the present application has been described in detail in the foregoing embodiments, those skilled in the art should understand that the foregoing embodiments can still be modified, or some technical features therein can be replaced by equivalents. These modifications or replacements do not make the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.

[0101] The above is an exemplified description of the thermal insulation external wall panel of the present application, and mainly describes the improved part thereof. For the remaining structure of the thermal insulation external wall panel, the related structure configuration of the existing thermal insulation external wall panel can be referred to or used, such as the structural relationship of the tenon 1 and the mortise 6, the configuration of the fastening member such as the bolt 4, and the like, which will not be described herein.
