Description

Technical Field

[0001] The utility model relates to a positioning tool for an insulation board in the production process of the insulation board. The utility model further relates to an insulation wall board produced based on the insulation board positioning method, and a building using the insulation wall board. Background Art

[0002] Chinese patent document CN117260963A is a patent document on self-insulating wall panels proposed by Shandong Chunguangli New Materials Technology Co., Ltd. In view of the relatively detailed description of the self-insulating wall panels in this patent document, the full text is quoted here and will not be repeated here.

[0003] Self-insulating wall panels can be understood as wall panels with embedded insulation boards or with insulation layers formed inside. The utility model belongs to the application of embedded insulation boards. Specifically, in the process of preparing insulation wall panels, prefabricated insulation boards are used as insulation materials, and the insulation boards are positioned on predetermined tooling together with mesh cages (also known as rib cages), and then lowered into a given casting mold for casting, and then subsequent processing is performed to form insulation wall panels. One of the key points in this process is the positioning of the insulation boards.

[0004] Since the insulation wallboard was proposed relatively late, the positioning of the insulation board and the corresponding positioning method have been put into use, but the effect still needs to be verified for a long time. The inventor believes that the positioning of the insulation board needs to consider multiple factors, namely the specifications of the insulation board, the position relationship between the mesh cage and the insulation board, the influence of the existence of the insulation board on the strengthening effect of the mesh cage, and the mutual influence between the positioning of the mesh cage and the positioning of the insulation board.

[0005] Relatively speaking, reinforced wall panels (mainly reinforced exterior wall panels) appeared earlier, so the positioning technology for reinforced wall panels, such as steel mesh cages, has been very mature. In the current insulation wall panel manufacturing process, the positioning of the insulation board usually relies on the tooling such as steel mesh cages (another common mesh cage is FRPC, which is the abbreviation of Fiber Reinforced Polymer Cage) or the steel mesh cage itself after being positioned. In some implementations, since the steel mesh cage usually includes at least two steel mesh sheets, the insulation board is clamped between the two steel mesh sheets. Obviously, the spacing of the steel mesh sheets is often fixed. In other words, the size specifications of the insulation board will be limited by this, and the flexibility in selecting the size specifications of the insulation board is not enough. At the same time, when the insulation board is close to the steel mesh, the cement cannot cover the steel bars, and the depth of the steel bars embedded in the cement in the wall panel (also known as the depth of the embedded steel bars) has standard requirements, such as the depth of the embedded steel bars is 8 to 15 times the diameter of the steel bars. If the embedded steel bars are relatively shallow or directly exposed, it will seriously affect the strength of the wall panel. It can be seen that directly using steel mesh to position the insulation board not only affects the selection of the insulation board size specifications, but also affects the overall strength of the insulation wall panel.

[0006] In some implementations, for example, a steel mesh is still used as the installation base, but in order to avoid the problem of the insulation board being too close to the steel mesh, which results in a relatively shallow depth of the embedded steel bars, an oblique insert is used to fix the position of the insulation board, and two pairs of X-shaped or V-shaped steel wires can be supported on the steel mesh. Although oblique inserts are a relatively common technology in the field of wall panel technology and are very mature, the positioning accuracy of the oblique inserts is not high, and the mold cavity used in the current production of self-insulating wall panels is relatively large, and the impact of cement slurry during feeding is relatively large, which can easily cause the insulation board to shift.

[0007] Since the mesh cage is often positioned using a special tool, the special tool includes a vertically arranged drill rod, a connector generally made of plastic material is mounted on the drill rod, and the connector has a seat configured with the drill rod. The connector also includes a pair of arms extending radially from the seat, and the two arms are generally axially symmetrically configured, and the end of the arm has a hook to hook and pull the steel mesh. It can be seen that the drill rod is located between a pair of adjacent steel meshes, so in some implementations, the insulation board can be directly strung on the drill rod. However, since the number of connectors has standard requirements, in other words, the spacing of the connectors is also determined, the connector and the insulation board are both mounted on the drill rod as a base, so that the set position on the drill rod will have a mutual influence. At the same time, if the insulation board is inserted into the drill rod, it is necessary to pre-open a hole on the insulation board, which will inevitably increase the process difficulty. If the insulation board is directly inserted without pre-opening, since the drill rod is relatively thick, and the collimation during the insertion process is not well controlled, it is easy to wear off or the insulation board is easy to burst.

[0030] According to a second aspect of an embodiment of the utility model, there is provided a thermal insulation wall panel, which is prepared using the thermal insulation panel positioning tooling described in the first aspect of the embodiment of the utility model, and is characterized in that the thermal insulation wall panel comprises:

[0031] Autoclaved aerated concrete matrix;

[0039] It should be known that the current tooling for autoclaved aerated concrete wall panels is only provided with a steel bar for positioning and fixing the mesh cage. In the embodiment of the utility model, the steel bar is equivalent to the main bar.

Under this condition, due to the intervention of the auxiliary bar, the positioning of the insulation board does not rely on or does not completely rely on the main bar to realize the positioning, so that the position relationship with the mesh cage will become more flexible. Under this condition, the distance between the insulation board and the mesh of the mesh cage can be effectively controlled, so that the depth of the embedded reinforcement of the mesh is weakened by the position of the insulation board, and the mutual influence between the positioning of the insulation board and the positioning of the mesh cage is small. At the same time, since it does not need to rely on or not completely rely on the main bar, and does not rely on the mesh cage, under this condition, the insulation board can be directly clamped between the auxiliary bars or between the auxiliary bars and the main bars, which can greatly improve the installation efficiency of the insulation board on the insulation board positioning tooling. In addition, due to the provision of the auxiliary soldering iron, under this condition, the size of the insulation board can be relatively large, and the overall installation efficiency is also higher than that of the insulation board with relatively small size.

[0057] It should be known that, as far as thermal insulation wall panels are concerned, they have the typical lath characteristics like conventional wall panels, that is, the board condition with a relatively large length-to-width ratio, and their length is generally not less than 2.5m, and there are currently wall panels as long as 6m. Their width is usually not less than 30cm, but it is extremely rare to have a thickness greater than or equal to 120cm. The thickness of the wall panels rarely exceeds 38cm, but is generally greater than or equal to 25cm. It can be seen that the length: width: thickness of wall panels, including thermal insulation wall panels, is relatively large, and they have typical lath characteristics.

[0058] The same is true for the insulation board 8. Although the aspect ratio of the insulation board 8 is close to 1:1 in some implementations, its long side is generally greater than its wide side, and its length to thickness ratio is often greater than 10.

[0059] In principle, the width corresponds to the horizontal direction, but for the insulation board positioning tooling, it is often set up in a frame-upper manner, and it is not a single piece of molded insulation wallboard, but a large blank is formed each time, and the blank is cut after solidification to form a single insulation wallboard. In the blank, the length direction of the insulation wallboard is often parallel to the horizontal plane. However, it should also be known that for the wallboard, the layout direction of the main braze 4 can be completely consistent with the length direction of the wallboard. At this time, if Figure 1 There is almost no positional interference between the supporting connecting member 2 and the auxiliary brazing member 5 shown in FIG. Figure 1 In the illustrated structure, the extension direction of the main dowel 4 is perpendicular to the length direction of the thermal insulation wallboard, and at this time, the auxiliary dowel 5 needs to avoid the position of the supporting connector 2.

[0060] The positioning and installation method of the mesh cage attached to the main drill 4 is common knowledge in the art and will not be described in detail in the embodiments of the present utility model.

[0061] Relatively speaking, if a relatively large insulation board 8 is used, Figure 4 The supporting connector 2 shown in the figure and located between the two side panels of the insulation board 8 can be omitted, and the supporting connector 2 is mainly connected by the supporting connector 2 arranged around the insulation board 8.

[0062] It should be noted that the support connectors 2 currently used are generally hot-melt plastic parts, which are not used to strengthen the structure of the insulation wall panels in principle. Although in some implementations, the support connectors 2 are made of metal parts (in this case, the support connectors 2 can be used as ribs to strengthen the insulation wall panels), the commonly used support connectors 2 are still mostly plastic parts whose hot-melt temperatures are lower than the steaming temperature of the insulation wall panels.

[0063] Furthermore, it can be seen that the supporting connector 2 can be used as a component for positioning the thermal insulation board 8 or as a constraint for clamping the thermal insulation board 8 .

[0064] It should be known that the mesh cage actually exists only in an assembled state, although prefabricated mesh cages exist in some implementations. However, most mesh cages often include two or three mesh sheets 3, and multiple mesh sheets 3 are assembled with each other using supporting connectors 2 in a positioning tool.

[0065] Some of the supporting connectors 2 are generally installed on the main drill 4 in a set manner. In some implementations, the set is achieved with the help of an interference fit (also called interference connection) between the supporting connector 2 and the main drill 4. In more implementations, in addition to the interference fit, in order to ensure the state stability of the mesh cage, the supporting connector 2 mounted on the main drill 4 can also use other components for auxiliary positioning, such as a casing, to position the supporting connector 2 in the rod direction of the main drill 4.

[0066] In the embodiment of the utility model, the known mesh cage positioning and installation method is firstly adopted, but the position of the mesh cage can also be adjusted according to, for example, the position of the auxiliary braze 5 or the design position of the insulation board 8. Considering the depth of the embedded reinforcement, the mesh cage tries to adopt traditional position design parameters.

[0067] It should be noted that, no matter it is pasted or cast-in-place, the thickness of the insulation board 8 is not large relative to the thickness of the wall. The thickness of the insulation board 8 ranges from 30mm to 120mm, but the different thicknesses of the insulation board 8 are mainly used for exterior wall leveling. In other words, for some new insulation boards with relatively good insulation effects, such as GPES and GPIR insulation boards, a thickness of 30mm can basically meet the current requirements for exterior wall insulation. Therefore, in the insulation wall panel, the insulation board 8 may have only one layer, and in some embodiments, the insulation board 8 may have two layers in the insulation wall panel.

[0068] The spacing between the mesh sheets 3 in the mesh cage is usually greater than 10 cm, and in more applications it is greater than 15 cm. Although the presence of the insulation board 8 will make the embedded depth of the mesh sheets 3 in the mesh cage relative to the insulation board 8 relatively small, the distance between the mesh sheets 3 and the position of the insulation board 8 in the currently known insulation wall panels is less than or equal to 20 mm. Based on the insulation wall panels of the embodiments of the utility model, the position of the insulation board 8 can be flexibly adjusted within the space where the two mesh sheets 3 are located, so that the distance between the mesh sheets 3 and the insulation board can be as large as possible while satisfying the condition that the insulation board 8 is built-in. At this time, the mesh sheets 3 have a relatively large embedded depth of reinforcement relative to the insulation board 8, thereby ensuring that the insulation wall panels have relatively greater structural strength.

[0069] It can be seen that the insulation board positioning tooling based on the embodiment of the utility model is used for positioning the mesh cage on the one hand, and for positioning the insulation board 8 on the other hand. The positioning of the mesh cage can be completely based on the known mesh cage positioning method, mainly using the main braze 4 as the positioning base, and generally using part or all of the supporting connectors 2 to achieve the positioning of the mesh cage. In more applications, two or three parallel mesh sheets 3 are actually connected by the supporting connector 2, and the middle part of part or all of the supporting connectors 2 is set or fixed on the main braze 4 in other ways. At this time, the main braze 4 is located in the middle position of the mesh cage, or the middle position of the two parallel mesh sheets 3 in the direction perpendicular to the mesh sheets 3. At this time, the insulation board can also be set in the center, or one side of the arrangement of the main braze 4 based on the arrangement of the main braze 4 can be offset.

[0070] Both the main drill 4 and the auxiliary drill 5 can be fixed in the traditional way of fixing the main drill 4. Generally speaking, as mentioned above, the main drill 4 is usually fixed on the frame in a downward hanging manner. The frame can be a plate structure or a longitudinal and transverse beam structure. It only needs to meet the requirements of, for example, the hanging installation of the main drill 4, and it is not required to be a plate or frame structure.

[0071] For one thermal insulation wallboard, at least two main pins 4 are configured, and then the two main pins 4 can be used to position the mesh cages used by multiple thermal insulation wallboards vertically, but it does not affect the fact that one thermal insulation wallboard needs at least two main pins 4 to position the mesh cages used by it. As mentioned above, one blank often needs to be cut into several thermal insulation wallboards. Under this condition, the main pins 4 are often arranged according to the predetermined blank design.

[0072] Correspondingly, the upper end of the main drill 4 is fixed on the frame and cantilevered downward, and the supporting connector 2 can be inserted into the main drill 4 from the lower end of the main drill 4. In some examples of supporting connectors 2 with side inlets on the seat, they can be clamped on the main drill 4 from the side.

[0073] The known main drill 4 is mainly used as the positioning matrix of the mesh cage, and for example Figure 1 The anchoring assembly 1 shown in the figure can be connected to the mesh 3 of the cage, and can also be directly or indirectly connected to the main drill 4 in other ways; in addition, the tie assembly 7 shown in the figure is generally directly connected to the anchoring assembly 1.

[0074] Since the anchoring assembly 1 is not a necessary configuration for the wallboard, the tie assembly 7 does not necessarily need to be integrated with the wallboard when the wallboard is manufactured, but can be provided after the wallboard is manufactured. Figure 1 The anchor assembly 1 and the tie assembly 7 in the positioning tool illustrated in the figure are not necessarily required to be configured. At the same time, it can also be seen from this that even if the tie assembly 7 is present, the anchor assembly 1 is not necessarily required to be configured. In some applications, after the wallboard is solidified or steamed, a tie hole can be directly opened at a predetermined position, and the bolt rod in the tie assembly 7 can be inserted into the tie hole without presetting the anchor assembly 1 in advance. The contents of the anchor assembly 1 and the tie assembly 7 are common knowledge in the art and will not be repeated here.

[0075] The fixing method of the auxiliary rod 5 can be the same as that of the main rod 4 or different, and the main rod 4 has a higher load-bearing capacity than the auxiliary rod 5. In addition, due to the various sizes and specifications of the insulation wallboard, the main rod 4 itself can be fixed in a non-detachable manner, while the auxiliary rod 5 is preferably fixed to the frame in a detachable connection manner to facilitate the replacement and adjustment of the auxiliary rod 5.

[0076] The number of auxiliary soldering bars 5 can be more or less than the number of main soldering bars 4 , and the design basis is the size specification of the insulation board 8 and the reliability of positioning and clamping.

[0077] It should be noted that, although the positioning of the insulation board 8 is achieved by relying on the auxiliary soldering iron 5 and, in some embodiments, the main soldering iron 4, and when necessary, the positioning of the insulation board 8 can be assisted by the support connector 2, but positioning and clamping are a pair of concepts, and in some cases the two can exist at the same time, that is, clamping is achieved while positioning is achieved, but in more applications, positioning is positioning, and clamping is clamping. Therefore, in some embodiments, in addition to the main soldering iron 4 and the auxiliary soldering iron 5, some accessories can be added to improve the positioning reliability of the insulation board 8 and the realization of clamping.

[0078] As mentioned above, the main solder joint 4 can be parallel or perpendicular to the length direction of the insulation wallboard. Different arrangements will lead to different arrangements of the auxiliary solder joints 5, mainly because they need to avoid interference with the position of the supporting connector 2.

[0079] If the main solder joint 4 is parallel to the length direction of the insulation wall panel, then the arrangement direction of the mesh 3 and the main solder joint 4 is parallel, the supporting connector can have two arms and cantilever on both sides, and the supporting connector 2 can also be Y-shaped and X-shaped. When the supporting connector 2 adopts the latter two structures, the auxiliary solder joint 5 can be arranged in parallel with the main solder joint 4.

[0080] Next, let's look at the arrangement of the auxiliary brazing rods 5 and how to achieve the positioning of the insulation board 8. The first way is that the positioning of the insulation board 8 is completely achieved by the auxiliary brazing rods 5. Therefore, each insulation board 8 requires at least two pairs of auxiliary brazing rods 5 to clamp it. Although three auxiliary brazing rods 5 based on a triangular arrangement can also clamp the insulation board 8, it is easy to cause the insulation board to deform. However, in some implementations, the rod body 51 of the auxiliary brazing rod 5 can be a sheet-like body to facilitate the fit with the board surface of the insulation board 8, thereby achieving a larger bonding area and having better positioning performance. In this case, three auxiliary brazing rods 5 can be used to position the insulation board 8.

[0081] When the auxiliary soldering iron 5 is used alone to position the heat-insulating plate 8, the position of the main soldering iron 4 is less affected, so that the position setting of the heat-insulating plate 8 can be more flexible.

[0082] In some embodiments, the insulation board 8 can be clamped between the main drill 4 and the auxiliary drill 5. At this time, the position of the insulation board 8 will inevitably be affected by the position of the main drill 4, but the total number of drill rods used can be saved.

[0083] Considering that the number of main soldering irons 4 may be relatively small, under the condition that the main soldering irons 4 are used to position the insulation boards 8, some insulation boards 8 can also be positioned using the auxiliary soldering irons 5 alone.

[0084] The positioning method implemented above is mainly clamping positioning, but in some embodiments, the auxiliary drill 5 can be made of a thinner drill rod than the main drill 4, because it is mainly used for positioning the relatively light insulation board 8, and the rigidity requirement of the auxiliary drill 5 itself is relatively low. Under this condition, the auxiliary drill 5 can be relatively thin, and the insulation board 8 can be inserted and positioned, which is not easy to cause the insulation board 8 to expand and crack. Relatively speaking, the reliability of insertion positioning is better, and clamping is achieved at the same time.

[0085] In addition, the insertion and matching clamps can make full use of the relatively large rigidity of the main drill 4, that is, the main drill 4 is used to realize the positioning of a board surface of the insulation board 8. The positioned board surface is guided by the main drill 4, so that the insulation board 8 slides on the main drill 4, and then the auxiliary drill 5 penetrates the insulation board 8, and finally the insulation board 8 is positioned with the help of the connection of the main drill 4 and the insertion of the auxiliary drill 5.

[0086] Similarly, if the insulation board 8 is not positioned by the main soldering iron 4, part of the auxiliary soldering iron 5 can provide contact positioning, that is, the part of the auxiliary soldering iron 5 provides the aforementioned engagement positioning similar to the main soldering iron 4 for the insulation board 8, and the remaining auxiliary soldering iron 5 provides interlacing positioning.

[0087] The insulation wall panel may have one insulation layer or two insulation layers. Having more than two insulation layers is a disadvantageous option and is not recommended. In principle, the insulation boards 8 in each insulation layer are located on the same distribution plane, and the outer surfaces of the insulation boards 8 in the same insulation layer are ensured to be coplanar as much as possible.

[0088] The same insulation layer in the same insulation wallboard can be composed of only one insulation board 8, or can be composed of multiple insulation boards 8 arranged in the length direction of the insulation wallboard, and there can be intervals between them, which form a connection between the cement boards on both sides of the insulation board layer after the slurry is filled and cured. However, this method will also lose some insulation effect.

[0089] The insulation boards 8 of the same insulation layer included in the same insulation wallboard all need to be reliably positioned. Therefore, corresponding to one insulation board 8, the auxiliary brazing rod 5 is located on one side or both sides of the main brazing rod 4; Figure 2 As shown, Figure 2 In the figure, the auxiliary drill 5 is located on the right side of the main drill 4. At this time, the main drill 4 and the auxiliary drill 5 work together to realize the positioning of the insulation board 8. At this time, there is only one insulation layer, and the insulation layer is biased to the right, and the distance with the mesh 3 on the left is larger, and the distance with the mesh 3 on the right is smaller. Under this condition, the embedded depth of the mesh 3 on the left relative to the insulation board 8 is easy to ensure, and the embedded depth of the mesh 3 on the right relative to the insulation board 8 is relatively small.

[0090] Therefore, in some embodiments, the positioning of the inner and outer surfaces of the insulation board 8 does not rely on the main brazing rod 4 for positioning, but uses two sets of auxiliary brazing rods 5 for positioning. Figure 2 It can be seen that the main dowels 4 are arranged in the center of the thickness direction of the insulation wall panel. When two groups of auxiliary dowels 5 are used to position the insulation board 8, the two groups of auxiliary dowels 5 can be arranged with the mid-section of the thickness of the insulation wall panel as the symmetry plane. At this time, the two meshes 3 are at basically the same distance from the insulation board 8. Under the condition that the thickness of the insulation board 8 is determined, the embedding depth of the mesh 3 relative to the insulation board 8 is easier to ensure.

[0091] Figure 3 It shows the arrangement of the auxiliary soldering rods 5 in another embodiment. At this time, the spacing between the two groups of auxiliary soldering rods 5 is relatively large. Therefore, the positioning of the insulation board 8 is achieved by cooperating between the two groups of auxiliary soldering rods 5 and the main soldering rod 4. At this time, there are two corresponding insulation layers. Compared with the example with a single insulation layer, under the condition that the total thickness of the insulation layer is equivalent, the thickness of each insulation layer can be relatively small, thereby reducing the impact on the embedding depth of the mesh 3 relative to the insulation board 8.

[0092] Based on the above description, it can be known that the auxiliary solder 5 adopts the interlacing positioning and the clamping positioning between the auxiliary solder 5 and the main solder 4 or other auxiliary solder 5 to the insulation board 8. Both methods have their own advantages and disadvantages. The interlacing positioning can also achieve clamping, and the clamping can also achieve clamping to some extent, but the effect is not as good as the interlacing. Relatively speaking, the positioning efficiency achieved by the clamping is higher.

[0093] Furthermore, if the auxiliary drill 5 is located on one side of the main drill 4, Figure 2 In the illustrated case, the space between the auxiliary braze 5 and the main braze 4 can be directly used to clamp the insulation board 8, and the clamp positioning is realized. As an alternative, the main braze 4 provides joint support for the insulation board 8, and the insulation board 8 is guided by the main braze 4, that is, the upper end face of the insulation board 8 is aligned with the auxiliary braze 5, and the board surface of the insulation board 8 supports and guides the main braze 4, and then slides along the main braze 4 to gradually insert the auxiliary braze 5 into the insulation board 8 until it is in place, and the insulation board 8 is inserted on the auxiliary braze 5, at which time the joint support of the main braze 4 for the insulation board 8 and the insertion positioning of the insulation board 8 provided by the auxiliary braze 5 are formed. The two methods prepare an insulation wall panel with a single insulation layer.

[0094] Figure 3The example of the insulation board positioning tool shown has been mentioned in the previous text. As can be seen in the figure, the auxiliary drill 5 is located on both sides of the main drill 4. The space between the two groups of auxiliary drills 5 can be used to position the insulation board 8. In some embodiments, the space between each group of auxiliary drills 5 and the main drill 4 can also be used to position the insulation board 8. The main drill 4 only provides contact positioning due to its relatively large diameter, and the expression form is the same as above, that is, the main drill 4 is equivalent to providing guidance and contact support. The auxiliary drill 5 can provide the same positioning method as the main drill 4, and can also provide interlaced positioning, which will produce a variety of positioning methods. Specifically, the space between the two groups of auxiliary drills 5 is used for clamping and positioning of the insulation board, and the positioning method is the same as the main drill 4. This is the first positioning method. One group of auxiliary drills 5 provides joint support for the insulation board 8, and the other group of auxiliary drills 4 provides interlaced positioning for the insulation board 8. In the example where there are two groups of auxiliary drills 5 and the main drill 4 is not used, the corresponding example is still used to prepare a wallboard with a single insulation layer, corresponding to the second positioning method.

[0095] When there are two groups of auxiliary brazing rods 5, the auxiliary brazing rods 5 and the main brazing rods 4 are used to clamp the insulation board 8, that is, the clamping positioning method is also adopted, and each group of auxiliary brazing rods 5 and the main brazing rod 4 respectively clamp the insulation board 8 to form two insulation layers. As an alternative, the main brazing rod 4 provides joint support for the insulation board 8, and the auxiliary brazing rod 5 provides interlaced positioning for the insulation board 8. This method is also used to prepare a wallboard with two insulation layers, which is the third positioning method.

[0096] These three positioning methods have been repeatedly explained in the previous article, and their positioning principles and basic structures will not be repeated here.

[0097] Regarding the insulation board 8, since it is used in the preparation of autoclaved aerated concrete wall panels, the insulation board 8 needs to undergo a steaming step. Therefore, the insulation board 8 should use an insulation board 8 with a melting temperature higher than the steaming process temperature of the corresponding insulation wall panels.

[0098] The insulation board 8 needs to be an inorganic insulation board or an organic insulation board with a melting temperature higher than the process temperature of the autoclave aerated concrete wallboard to which the insulation board is applied. After the autoclave curing is completed, the insulation board 8 is at least positioned by the solidified concrete matrix.

[0099] Regarding the selection of organic insulation boards or other insulation boards with relatively low melting points, for example, the selection method includes a method in which the melting point is higher than the steaming process temperature by a temperature difference, and the temperature difference ranges from 5 to 20°C.

[0100] The process temperature of the autoclave will be different according to the different aerated concrete wall panels being cured. The process temperature of the autoclave in the production process of aerated concrete is generally between 170°C and 210°C, and the optimal temperature is 185°C to 205°C. It can be seen that different insulation boards can be selected according to the different autoclaved aerated concrete. Relatively speaking, for autoclaved aerated concrete with a relatively low autoclaved process temperature, the selection range of the insulation board 8 will be wider. On the contrary, the selection range of the insulation board 8 will be relatively narrow.

[0101] Among organic thermal insulation boards, the thermal insulation boards 8 with a melting temperature higher than, for example, 200° C. are mainly vacuum insulation boards and phenolic boards. With the development of technology, there may be other types of organic thermal insulation boards with a melting temperature higher than, for example, 200° C.

[0102] Especially as people pay more attention to building fire safety, more completely non-combustible insulation materials are coming out. Although these insulation materials are mainly inorganic insulation materials or composite insulation materials, some organic insulation materials also appear.

[0103] In addition, there are currently two main options for the bars in the reinforcement cage, one is the traditional steel bar, and the other is the FRP bar that has been gradually promoted and applied in recent years. There are also two common FRP bars, namely CFRP (Carbon Fibre-reinforced Polymer, carbon fiber reinforced composite material) bars and AFRP (Aramid Fibre-reinforced Polymer) bars, collectively referred to as FRP bars. The typical characteristics of FRP bars are that the tensile strength is not weaker than that of steel bars for construction, and no anti-corrosion is required. The thermal conductivity is weaker than steel bars, and the market price is relatively low, so it has its unique advantages in the construction field.

[0104] With the promotion and application of FRP bars, more and more construction projects are using FRP bars to replace steel bars. For this purpose, some standards have also emerged. For example, the group standard T / SDCEAS 30009-2023 "System Structure of Prefabricated Lightweight Concrete Composite Insulation Exterior Wall Panels (VPR)" (hereinafter referred to as the 30009 standard) directly adopts FRP bars and further stipulates fiber-reinforced reinforcement cages FRPC, which is the form of FRP bars in concrete exterior wall panels.

[0105] Figure 2 and Figure 3 In the illustrated structure, the insulation board 8 has one or two layers in the concrete matrix; however, it should be ensured that the total thickness of the concrete at the location where the insulation board 8 is provided should not be less than 100 mm.

[0106] If, with the development of technology, higher strength concrete can be obtained, it is still within the foreseeable space of the embodiments of the present utility model, and the total thickness of the concrete is allowed to be less than 100 mm.

[0107] As mentioned above, each insulation wall panel may have one or two insulation layers, and each insulation layer may be formed by a plurality of insulation boards 8 arranged at intervals. Under this condition, long-distance interruption of the concrete matrix can be avoided.

[0108] After the concrete is solidified, adjacent groups of insulation boards 8 are separated by partitions formed by concrete, and thus have relatively high strength.

[0109] Taking the overall strength into consideration, in order to improve the bonding ability and make the insulation wall panel more integrated, the insulation board 8 is grooved and / or provided with protrusions on the board surface and / or side, so as to increase the bonding area between the insulation board 8 and the concrete matrix. At the same time, since there are multiple protrusions on the corresponding bonding surface, it plays an auxiliary connection role.

[0110] It is easy to understand that for the concrete matrix, it is formed in the mold, and when pouring, the concrete slurry will intervene in e.g. Fig.10 The trapezoidal groove 82 shown in FIG. 1 becomes a concrete matrix after the concrete slurry solidifies, and the part inserted into the trapezoidal groove 82 forms a structure similar to a reinforcing rib. In other words, by means of, for example Fig.10 The structure of the thermal insulation board 8 shown in the figure can alleviate the weakening of the strength of the concrete matrix.

[0111] The slot may be Fig.12 The rectangular groove 84, dovetail groove, V-shaped groove, trapezoidal groove 82 or Fig.11 The specific structure of the corrugated groove 83 shown can be seen in the corresponding drawings and will not be described here one by one.

[0112] As for the protrusions, columnar protrusions, ridge-like protrusions, and lath-like protrusions can be selected.

[0113] In addition, regarding the distribution of the grooves on the insulation board 8, Fig.10 and Fig.12 The groove in the groove is a transverse groove, and in some embodiments, a longitudinal groove can be used. In addition, an oblique groove can also be adopted.

[0114] In some embodiments, longitudinal grooves, transverse grooves and oblique grooves may be used together to form crisscross grooves.

[0115] Furthermore, in some embodiments, Figure 7The illustrated insulation board 8 is provided with a plurality of rib holes 81. After the concrete matrix solidifies, the concrete inserted into the rib holes 81 forms connecting ribs, thereby forming an additional connection between the concrete boards on both sides of the insulation board 8. At this time, the rib holes 81 are through holes.

[0116] also, Figure 7 The rib hole 81 may also be a blind hole, and the concrete inserted into the blind hole forms a bulge after solidification.

[0117] Taking many factors into consideration, the thickness of the insulation board 8 positioned by the insulation board positioning tool is 30~120mm, and the preferred range of the insulation board 8 is 40mm~80mm.

[0118] In view of the different requirements for the arrangement of the mesh cages in the insulation wall panels of different specifications, similarly, the requirements for the position of the insulation board 8 will also change. In order to improve the adaptability to the specifications of the insulation wall panels and the insulation board 8 of different specifications, the fixed beams and / or fixed plates used for fixing the main drill 4 and the auxiliary drill 5 and included in the frame are distributed with fixing holes, so that the positions of the main drill 4 and / or the auxiliary drill 5 can be adjusted according to the insulation wall panels and / or the insulation boards 8 of different specifications.

[0119] Relatively speaking, the position of the main drill 4 may be less adjustable or may not need to be adjusted, so the main drill 4 may be fixed to, for example, the crossbeam 6 or the upper frame plate by welding. However, it should be noted that many wallboard manufacturers have limited processing equipment, and in order to adapt to different specifications of insulation wallboards and insulation boards 8, the position of the main drill 4 on the frame is preferably adjustable.

[0120] For the auxiliary drill 5, its adjustability requirement is higher than that of the main drill 4. Therefore, Figure 8 As shown, at least the upper end of the auxiliary drill 5 has a stud 53, and the stud 53 passes through the fixing hole and is locked by a nut.

[0121] Considering that the auxiliary drill 5 needs to have a certain ability to resist lateral forces, the fixing hole should have a certain depth, which is preferably not less than 20 mm, but usually not more than 200 mm. The fixing hole forms a good radial restriction by cooperating with the axial hole between the auxiliary drill 5, and the auxiliary drill 5 can be effectively locked by cooperating with the nut.

[0122] Figure 8 The figure shows an exemplary structure of the auxiliary drill 5, which is also applicable to the main drill 4. It should be noted that the figure schematically shows a structure of the auxiliary drill 5. The diameter of the positioning ring 52 shown in the figure is obviously larger than the diameter of the fixing hole, and the rod body 51 is the main body for positioning. The stud 53 may not be a full thread, but may include a bare rod section that matches the fixing hole.

[0123] Figure 5 and Figure 6 The structure of a crossbeam 6 is shown, and three rows of holes are opened on the crossbeam 6 for the optional installation of the auxiliary dowels 5. In addition, the same crossbeam 6 can also have more rows of holes, which are suitable for the optional installation of the main dowels 4 and the auxiliary dowels 5. And when the main dowels 4 and the auxiliary dowels 5 used for positioning the same set of thermal insulation wall panels are located on the same crossbeam 6, the matching accuracy between the two can be better ensured.

[0124] exist Figure 5 and Figure 6 In the illustrated structure, one row of holes is formed of elongated holes 62 , which are used, for example, as fixing holes for the auxiliary drill 5 , so as to facilitate fine adjustment of the installation position of the auxiliary drill 5 in the extending direction of the elongated holes 62 .

[0125] The extending direction of the long hole 62 is the row arrangement direction. Figure 6 The extending direction of the elongated hole 62 is shown as an example. In some embodiments, the elongated hole 62 can also be perpendicular to the arrangement direction of the fixing holes. In some other embodiments, the extending direction of the elongated hole 62 forms an angle of 30° to 60° with the arrangement direction of the fixing holes.

[0126] In addition, regarding the fixation of the drill rods including the auxiliary drill rod 5 and the main drill rod 4, the nut used in conjunction with the stud 53 is preferably a handwheel nut 9, so as to facilitate the operator to quickly fix the corresponding drill rod.

[0127] Obviously, the corresponding nut may also be a hexagonal head nut, for example.

[0128] As mentioned above, since the positioning requirements of the auxiliary drill 5 are relatively low, its rigidity can be relatively low, and a drill rod with a smaller diameter can be selected relative to the main drill 4. Under this condition, the auxiliary drill 5 can be considered to be used as an insert drill, that is, a drill rod that can be directly inserted into the insulation board 8. Under this requirement, the diameter of the auxiliary drill 5 is preferably not greater than half the diameter of the main drill 4.

[0129] If the same positioning method as the main dowel 4 is used for the insulation board 8, the auxiliary dowel 5 can be slightly thicker, but in order to save costs and facilitate doweling, the diameter of the auxiliary dowel 5 should not be greater than 0.75 times the diameter of the main dowel.

[0130] Even if used as a plunger, the diameter of the auxiliary drill 5 should not be too small, otherwise it is easy to bend under the extrusion state, so the diameter of the auxiliary drill 5 should not be less than 0.15 times the diameter of the main drill 4. Relatively speaking, a thinner auxiliary drill 5 is more suitable for plunger use.

[0131] The end of the auxiliary drill 5 used as a drill can be a pointed tip to facilitate piercing the insulation board 8.

[0132] In addition, for the auxiliary brazing rod 5, Figure 8In the illustrated structure, the rod body 51 is cylindrical, while in some embodiments, the rod body 51 may be a sheet-shaped body, and the sheet surface of the sheet-shaped body is perpendicular to the direction of clamping the thermal insulation board 8 .

[0133] As mentioned above, for the main solder, the main solder 4 and / or the auxiliary solder 5 used for clamping the insulation board 8 are connected by a hot-melt connector outside the rod section used to clamp or insert the insulation board 8; it should be known that the "clamping" or "insertion" here is subject to the limitations of the "clamping" or "insertion" subject in the previous embodiments and is definite.

[0134] It should be known that before being sent to the curing kettle, the concrete has already solidified, and even if the connector is damaged, it will not cause the position of the insulation board 8 to change. However, after curing, if the connector still exists, it will affect the extraction of the main and auxiliary rivets 4 and 5. Therefore, in the preferred embodiment, the purpose of using the connector is to provide auxiliary positioning, but it should not affect the extraction of the rivets as much as possible. In view of this, the connector is made of hot-melt material, and it is obvious that the hot-melt temperature of the hot-melt is not higher than the curing temperature of the corresponding wallboard.

[0135] At this time, the connector can be made of the same material as the conventional supporting connector 2 .

[0136] As mentioned above, since the distance between the supporting connector 2 and the insulation board 8 does not affect the embedding depth of the mesh 3, the supporting connector 2 can provide additional positioning for the insulation board 8, especially supporting positioning.

[0137] exist Figure 2 In the illustrated structure, a group of supporting connectors 2 located on the upper side and a group of supporting connectors 2 located on the lower side can be used to clamp the insulation board 8.

[0138] In addition, as two-end constraints, Figure 2 Four supporting connectors 2 are used on one side, and the insulation board cannot pass through, but as the edge supporting connector 2, the end of the insulation board 8 can be positioned. At this time, the end positioning method is the end corresponding to the two ends of the insulation board 8.

[0139] The method of positioning the insulation board has been described very clearly in the previous description of the insulation board positioning tooling, and will not be repeated here.
